Resignation from Stefan Krah
by Antoine Pitrou Oct. 22, 2020

Oct. 22, 2020

Hello, Apparently, Stefan Krah (core developer and author of the C _decimal module) was silently banned or moderated from posting to python.org mailing-lists. He asked me to forward the following message: ================================================================================== Hello, Today I have left the Python organization. It wasn't an easy decision, after all there are so many amazing people here. My vision of how development should be handled differs from many people who are currently active. Other projects are more aligned with my preferences, so I prefer to focus my energies elsewhere. Having a shared understanding of what constitutes politeness is important and eliminates all sources of friction that sometimes result in losing one's patience. All the best, Stefan Krah ==================================================================================== Best regards Antoine.

Ah, cool, got it - thanks! My reading of this is that a good few of the benchmarks are coming out firmly in PyPy's favour, but a number of them are still in CPython's favour (including "telco" where PyPy is staggeringly worse for some reason). But a number of the "PyPy is worse" benchmarks are ones that seem less significant - for instance, SQLAlchemy seems to be slower, but if you're using SQLAlchemy, you're probably more concerned about database performance than the CPU cost inside Python. > For some reason the "permalink" feature does not let me share that > configuration. Yeah, there seem to be some issues with that page. The first time I loaded it, the chart was entirely broken - I was looking for the "show chart" button, but it was just that it had errored out for some reason. Still, at least the data's there. > I guess we could switch to emphasizing python3 on the front page, help > in updating and reconfiguring Codespeed [1] would be awesome. If only I had infinite time in the day, I'd love to dive in and help out... It definitely would be worth at least having a quick summary and link somewhere. ChrisA

PEP 640: Unused variable syntax.
by Thomas Wouters Oct. 21, 2020

Oct. 21, 2020

One of the problems I have with the Pattern Matching proposal (PEP 622 originally, now PEPs 634, 635, 636) is the special-casing of '_' to not actually assign to the name, which is a subtle but meaningful divergence from the rest of Python. In discussions with the authors I proposed using '?' instead *and* extending that to existing unpacking syntax. The PEP authors were understandably a little hesitant to tack that onto their already quite extensive proposal, so I suggested making it a separate proposal. That proposal is at https://www.python.org/dev/peps/pep-0640 (unless that hasn't updated yet, in which case it's at https://github.com/python/peps/blob/master/pep-0640.rst), and also included below. This proposal doesn't necessarily require pattern matching to be accepted -- the new syntax stands well enough on its own -- but I'm recommending this *not* be accepted if pattern matching using the same syntax is not also accepted. The benefit without pattern matching is real but small, and in my opinion it's not worth the added complexity. The PEP: PEP: 640 Title: Unused variable syntax Author: Thomas Wouters <thomas(a)python.org> Status: Draft Type: Standards Track Content-Type: text/x-rst Created: 04-Oct-2020 Python-Version: 3.10 Post-History: Abstract ======== This PEP proposes new syntax for *unused variables*, providing a pseudo-name that can be assigned to but not otherwise used. The assignment doesn't actually happen, and the value is discarded instead. Motivation ========== In Python it is somewhat common to need to do an assignment without actually needing the result. Conventionally, people use either ``"_"`` or a name such as ``"unused"`` (or with ``"unused"`` as a prefix) for this. It's most common in *unpacking assignments*:: x, unused, z = range(3) x, *unused, z = range(10) It's also used in ``for`` loops and comprehensions:: for unused in range(10): ... [ SpamObject() for unused in range(10) ] The use of ``"_"`` in these cases is probably the most common, but it potentially conflicts with the use of ``"_"`` in internationalization, where a call like gettext.gettext() is bound to ``"_"`` and used to mark strings for translation. In the proposal to add Pattern Matching to Python (originally PEP 622, now split into PEP 634, PEP 635 and PEP 636), ``"_"`` has an *additional* special meaning. It is a wildcard pattern, used in places where variables could be assigned to, to indicate anything should be matched but not assigned to anything. The choice of ``"_"`` there matches the use of ``"_"`` in other languages, but the semantic difference with ``"_"`` elsewhere in Python is significant. This PEP proposes to allow a special token, ``?``, to be used instead. This has most of the benefits of ``"_"`` without affecting other uses of that otherwise regular variable. Allowing the use of the same wildcard pattern would make pattern matching and unpacking assignment more consistent with each other. Rationale ========= Marking certain variables as unused is a useful tool, as it helps clarity of purpose of the code. It makes it obvious to readers of the code as well as automated linters, that a particular variable is *intentionally* unused. However, despite the convention, ``"_"`` is not a special variable. The value is still assigned to, the object it refers to is still kept alive until the end of the scope, and it can still be used. Nor is the use of ``"_"`` for unused variables entirely ubiquitous, since it conflicts with conventional internationalization, it isn't obvious that it is a regular variable, and it isn't as obviously unused like a variable named ``"unused"``. In the Pattern Matching proposal, the use of ``"_"`` for wildcard patterns side-steps the problems of ``"_"`` for unused variables by virtue of it being in a separate scope. The only conflict it has with internationalization is one of potential confusion, it will not actually interact with uses of a global variable called ``"_"``. However, the special-casing of ``"_"`` for this wildcard pattern purpose is still problematic: the different semantics *and meaning* of ``"_"`` inside pattern matching and outside of it means a break in consistency in Python. Introducing ``?`` as special syntax for unused variables *both inside and outside pattern matching* allows us to retain that consistency. It avoids the conflict with internationalization *or any other uses of _ as a variable*. It makes unpacking assignment align more closely with pattern matching, making it easier to explain pattern matching as an extension of unpacking assignment. In terms of code readability, using a special token makes it easier to find out what it means (``"what does question mark in Python do"`` versus ``"why is my _ variable not getting assigned to"``), and makes it more obvious that the actual intent is for the value to be unused -- since it is entirely impossible to use it. Specification ============= A new token is introduced, ``"?"``, or ``token.QMARK``. The grammar is modified to allow ``"?"`` in assignment contexts (``star_atom`` and ``t_atom`` in the current grammar), creating a ``Name`` AST node with identifier set to NULL. The AST is modified to allow the ``Name`` expression's identifier to be optional (it is currently required). The identifier being empty would only be allowed in a ``STORE`` context. In CPython, the bytecode compiler is modified to emit ``POP_TOP`` instead of ``STORE_NAME`` for ``Name`` nodes with no identifier. Other uses of the ``Name`` node are updated to handle the identifier being empty, as appropriate. The uses of the modified grammar nodes encompass at least the following forms of assignment:: ? = ... x, ?, z = ... x, *?, z = ... for ? in range(3): ... # including comprehension forms for x, ?, z in matrix: ... # including comprehension forms with open(f) as ?: ... with func() as (x, ?, z): ... The use of a single ``"?"``, not in an unpacking context, is allowed in normal assignment and the ``with`` statement. It doesn't really make sense on its own, and it is possible to disallow those specific cases. However, ``for ? in range(3)`` clearly has its uses, so for consistency reasons if nothing else it seems more sensible to allow the use of the single ``"?"`` in other cases. Using ``"?"`` in augmented assignment (``? *= 2``) is not allowed, since ``"?"`` can only be used for assignment. Backwards Compatibility ======================= Introducing a new token means there are no backward compatibility concerns. No valid syntax changes meaning. "?" is not considered an identifier, so str.isidentifier() does not change. The AST does change in an incompatible way, as the identifier of a Name token can now be empty. Code using the AST will have to be adjusted accordingly. How to Teach This ================= ``?`` can be introduced along with unpacking assignment, explaining it is special syntax for 'unused' and mentioning that it can also be used in other places. Alternatively, it could be introduced as part of an explanation on assignment in ``for`` loops, showing an example where the loop variable is unused. PEP 636 discusses how to teach ``"_"``, and can simply replace ``"_"`` with ``?``, perhaps noting that ``?`` is similarly usable in other contexts. Reference Implementation ======================== A prototype implementation exists at <https://github.com/Yhg1s/cpython/tree/nonassign>. Rejected Ideas ============== Open Issues =========== Should ``"?"`` be allowed in the following contexts:: # imports done for side-effect only. import os as ? from os import path as ? # Function defined for side-effects only (e.g. decorators) @register_my_func def ?(...): ... # Class defined for side-effects only (e.g. decorators, __init_subclass__) class ?(...): ... # Parameters defined for unused positional-only arguments: def f(a, ?, ?): ... lambda a, ?, ?: ... # Unused variables with type annotations: ?: int = f() # Exception handling: try: ... except Exception as ?: ... # With blocks: with open(f) as ?: ... Some of these may seem to make sense from a consistency point of view, but practical uses are limited and dubious. Type annotations on ``"?"`` and using it with ``except`` and ``with`` do not seem to make any sense. In the reference implementation, ``except`` is not supported (the existing syntax only allows a name) but ``with`` is (by virtue of the existing syntax supporting unpacking assignment). Should this PEP be accepted even if pattern matching is rejected?

Pickle for C extension?
by Marco Sulla Oct. 20, 2020

Oct. 20, 2020

TL;DR Is it possible to use C code to implement the (un)pickling of an type written in a C extension, as it was written in _pickle.c? Long explaining: I'm trying to create a C extension for frozendict. For simplicity, first I wrote it in CPython, then I started to move it in a C extension. It seems to work, but I have to move the code I wrote in _pickle.c and pickle.py in the C extension. Is it possible, or I have to create a slower `__reduce_ex__` method that simply converts it to dict? This is, for example, the C code for pickling frozendict in _pickle.c: https://github.com/Marco-Sulla/cpython/blob/41a640a947c36007e56bbc28f362c26…

Changing Python's string search algorithms
by Tim Peters Oct. 19, 2020

Oct. 19, 2020

Fredrik Lundh crafted our current string search algorithms, and they've served us very well. They're nearly always as fast as dumbest-possible brute force search, and sometimes much faster. This was bought with some very cheap one-pass preprocessing of the pattern (the substring to search _for_), to compute a single integer "skip", and a single 32-bit bitmask, which can sometimes be used to skip over areas where it can prove matches are doomed to fail. Unlike most "fancier than brute" algorithms, it does not build preprocessing tables of size proportional to the length of the pattern, or to the size of the alphabet. The extra space is O(1), and tiny, independent of pattern and alphabet size. A weakness is that worst-case search time is proportional to the product of the lengths of the inputs. This can be so for searches that succeed as well as for those that fail. This was recently dramatically illustrated by this bug report: https://bugs.python.org/issue41972 where a single large string search consumed well over 3 hours of CPU time before it succeeded. It "should take" a fraction of a second. While it was news to me, Dennis Sweeney was aware of that other algorithms requiring only O(1) extra space are now well known with worst-case linear time. That's really quite remarkable :-) They do require fancier (but still linear-time) preprocessing, so can't always be a pure win. So this message: string (which includes byte) search is an extremely common operation, across all kinds of applications, so changes here need as many eyeballs on them as they can get. What's typical? What's important? What doesn't matter? What about reverse searches ("rfind")? How can we quantify the acceptable region of tradeoffs? My guess is that searches for substrings less than 50 characters long in strings under ten thousand characters are most important for most apps, but I just pulled that guess out of my butt. I'm also guessing that searches for multi-million-character substrings (like in the bug report above) are rare indeed, and that any change sparing them from quadratic-time disaster would be "way more than good enough". But I don't know. If you can help, Dennis already has a preliminary PR implementing one of the newer algorithms, augmented with Fredrik's unique ideas: https://github.com/python/cpython/pull/22679 By "help" I don't necessarily mean code review - it could, e.g., be a huge help to test-drive it on your own critical string-slinging apps. Faster? Slower? A wash? Wrong answer? Crash? Due to the natures of the old and new algorithms, neither will be faster or slower in all cases, the newer one should never be dramatically slower than the old one, the new one will be spectacularly faster in some cases, and "in general" it seems impossible to guess in advance. It depends on the value the fancier preprocessing can extract from the pattern versus the higher preprocessing cost, and that in turn depends on details of exactly what the patterns and texts to be searched are.

Modified parser does not seem to work. What am I doing wrong?
by Stefano Borini Oct. 17, 2020

Oct. 17, 2020

Hello, I am trying to implement PEP-637, and I started modifying the parser and the grammar, but I don't know what I am missing. The PR is here https://github.com/python/cpython/compare/master...stefanoborini:PEP-637-im… It includes other stuff but the core is that I extended the Subscript in the asdl to accept the keyword args | Subscript(expr value, expr slice, keyword* keywords, expr_context ctx) which seems to work: >>> ast.parse('a[3]').body[0].value.keywords [] I also added a few "productions" (I believe they are called like this, my compiler theory is very approximated), one of which is now primary[expr_ty]: .... | a=primary '[' b=slices c=[',' k=kwargs {k}]']' { _Py_Subscript(a, b, c, Load, EXTRA) } I also tried with additional formats like | a=primary '[' b=slices c=kwargs ']' { _Py_Subscript(a, b, c, Load, EXTRA) } or even just | a=primary '[' c=kwargs ']' { _Py_Subscript(a, NULL, c, Load, EXTRA) } but I always get a SyntaxError: >>> ast.parse('a[k=3]').body[0].value.keywords Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/sbo/Work/Projects/stefanoborini/cpython/Lib/ast.py", line 50, in parse return compile(source, filename, mode, flags, File "<unknown>", line 1 a[k=3] ^ SyntaxError: invalid syntax Note that I always recreated ast parser and pegen.c with 'make regen-all' and recompiled with make. I tried to enable debug and print the pegen.c debug, but it's a bit heavy and I could not immediately spot the issue. I suspect I am missing something somewhere. Thanks -- Kind regards, Stefano Borini

Drop support for AIX releases without dlopen
by kadler＠us.ibm.com Oct. 16, 2020

Oct. 16, 2020

Python has supported using dynload_shlib (using dlopen) on AIX since https://github.com/python/cpython/commit/c19c5a62aef7dce0e8147655b0d2f08796… in 2003. Considering this is now 20 years later and all supported AIX versions support dlopen, I suspect nobody has used or tested this code path in quite some time. I propose removing this support under PEP 11. For reference, I opened https://bugs.python.org/issue42030 and changes were merged in https://github.com/python/cpython/pull/22717. I opened a PR to update PEP 11 in https://github.com/python/peps/issues/1653, but was told this needed discussion here. Sorry if this didn't quite follow the process correctly, I thought I had things in the right order, but I guess not.

Remove module's __version__ attributes in the stdlib
by Serhiy Storchaka Oct. 16, 2020

Oct. 16, 2020

Some module attributes in the stdlib have attribute __version__. It makes sense if the module is developed independently from Python, but after inclusion in the stdlib it no longer have separate releases which should be identified by version. New changes goes into module usually without changing the value of __version__. Different versions of the module for different Python version can have different features but the same __version__. I propose to remove __version__ in all stdlib modules. Are there any exceptions? Also, what do you think about other meta attributes like __author__, __credits__, __email__, __copyright__, __about__, __date__?
