What to do about invalid escape sequences
by raymond.hettinger＠gmail.com 15 Aug '19

15 Aug '19

We should revisit what we want to do (if anything) about invalid escape sequences. For Python 3.8, the DeprecationWarning was converted to a SyntaxWarning which is visible by default. The intention is to make it a SyntaxError in Python 3.9. This once seemed like a reasonable and innocuous idea to me; however, I've been using the 3.8 beta heavily for a month and no longer think it is a good idea. The warning crops up frequently, often due to third-party packages (such as docutils and bottle) that users can't easily do anything about. And during live demos and student workshops, it is especially distracting. I now think our cure is worse than the disease. If code currently has a non-raw string with '\latex', do we really need Python to yelp about it (for 3.8) or reject it entirely (for 3.9)? If someone can't remember exactly which special characters need to be escaped, do we really need to stop them in their tracks during a data analysis session? Do we really need to reject ASCII art in docstrings: ` \-------> special case'? IIRC, the original problem to be solved was false positives rather than false negatives: filename = '..\training\new_memo.doc'. The warnings and errors don't do (and likely can't do) anything about this. If Python 3.8 goes out as-is, we may be punching our users in the nose and getting almost no gain from it. ISTM this is a job best left for linters. For a very long time, Python has been accepting the likes of 'more \latex markup' and has been silently converting it to 'more \\latex markup'. I now think it should remain that way. This issue in the 3.8 beta releases has been an almost daily annoyance for me and my customers. Depending on how you use Python, this may not affect you or it may arise multiple times per day. Raymond P.S. Before responding, it would be a useful exercise to think for a moment about whether you remember exactly which characters must be escaped or whether you habitually put in an extra backslash when you aren't sure.

It all works - wheels for AIX - up to a point
by Michael 15 Aug '19

15 Aug '19

Spent some hours - experimenting... So - short story - it works. There remains a big chance for failure though as the current tag ignores differences in TL level, build_date, etc.. Also, a source for failure, is no recognition for 32-bit or 64-bit. However, focusing on the good news - the wheels install - without a compiler being called. Looking Forward!! AIX has a long history of letting binaries from the past be reused: See: https://www.ibm.com/support/knowledgecenter/ssw_aix_72/install/binary_compa… ++++++ The gritty details, for the curious/interested After having used devpi (client) to upload to a test devpi-server I pointed my pip at the devpi-server to download the packages. Note: using default pipy "source" I would get two .gz files. The initial upload is from an AIX 6.1 server, the download here is to an AIX 7.1 server.

Snapshot formats in tracemalloc vs profiler
by Yonatan Zunger 14 Aug '19

14 Aug '19

Hi everyone, Something occurred to me while trying to analyze code today: profiler and cProfiler emit their data in pstats format, which various tools and libraries consume. tracemalloc, on the other hand, uses a completely separate format which nonetheless contains similar data. In fact, in many non-Python applications I've worked in, heap and CPU profiles were always emitted in identical formats, which allowed things like visual representations of stack traces where memory is allocated, and these have proven quite useful in practice and allowed lots of sharing of tools across many applications. Is there a particular design reason why these formats are different in Python right now? Would it make sense to consider allowing them to match, e.g. having a tracemalloc.dump_pstats() method?

Raw string literals and trailing backslash
by Serhiy Storchaka 13 Aug '19

13 Aug '19

Currently a raw literal cannot end in a single backslash (e.g. in r"C:\User\"). Although there are reasons for this. It is an old gotcha, and there are many closed issues about it. This question is even included in FAQ. The most common workarounds are: r"C:\User" "\\" and r"C:\User\ "[:-1] I tried to experiment. It was easy to make the parser allowing a trailing backslash character. It was more difficult to change the Python implementation in the tokenizer module. But this change breaks existing code in more sites than I expected. 14 Python files in the stdlib (not counting tokenizer.py) will need to be fixed. In all cases it is a regular expression. Few examples: 1. r"([\"\\])" If only one type of quotes is used in a string, we can just use different kind of quotes for creating a string literal and remove escaping. r'(["\\])' 2. r'(\'[^\']*\'|"[^"]*"|...' If different types o quotes are used in different parts of a string, we can use implicit concatenation of string literals created with different quotes (in any case a regular expression is long and should be split on several lines on semantic boundaries). r"('[^']*'|" r'"[^"]*"|' r'...' 3. r"([^.'\"\\#]\b|^)" You can also use triple quotes if the string contain both type of quotes together. r"""([^.'"\\#]\b|^)""" 4. In rare cases a multiline raw string literals can contain both `'''` and `"""`. In this case you can use implicit concatenation of string literals created with different triple quotes. See https://github.com/python/cpython/pull/15217 . I do not think we are ready for such breaking change. It will break more code than forbidding unrecognized escape sequences, and the required fixes are less trivial.

typing: how to use names in result-tuples?
by Christian Tismer 12 Aug '19

12 Aug '19

Hi friends, I am meanwhile the PySide maintainer at The Qt Company, and we are trying to make the mapping from Qt functions to Python functions as comparable as possible. One problem are primitive pointer variables: In Qt, it is natural to use "sometype *varname" to make a mutable variable. In Python, you have to turn such a thing into a result-tuple. Example: void QPrinter::getPageMargins(qreal *left, qreal *top, \ qreal *right, qreal *bottom, QPrinter::Unit unit) const (meanwhile deprecated, but a good example) is mapped to the Python signature def getPageMargins(self, \ unit: PySide2.QtPrintSupport.QPrinter.Unit) \ -> typing.Tuple[float, float, float, float]: ... NOW my question: ---------------- I would like to retain the variable names in Python! The first idea is to use typing.NamedTuple, but I get the impression that this would be too much, because I would not only need to create an extra named tuple definition for every set of names, but also invent a name for that named tuple. What I would like to have is something that looks like def getPageMargins(self, \ unit: PySide2.QtPrintSupport.QPrinter.Unit) \ -> typing.NamedTuple[left: float, top: float, \ right:float, bottom:float]: ... but that is obviously not a named tuple. Possible would be to derive a name from the function, so maybe a definition could be used like class PageMargingResult(NamedTuple): left: float top: float right: float bottom: float but then I would have some opaque PageMargingResult type. This would work, but as said, this is a bit too much, since I only wanted something like a tuple with names. What do you suggest to do here? Something what I am missing?

PEP 572 TargetScopeError
by Barry Warsaw 09 Aug '19

09 Aug '19

bpo-37757: https://bugs.python.org/issue37757 This issue describes some corner cases in PEP 572 (assignment expressions) syntax that haven’t been implemented yet. The PEP currently says: "The two invalid cases listed above raise TargetScopeError, a new subclass of SyntaxError (with the same signature).” The PEP doesn’t really go into the rationale for why a new exception is being defined, and in the issue I’ve argued that we should just raise SyntaxError in those cases. To me, “TargetScopeError” is pretty obscure and doesn’t give users an obvious clue as to what’s going wrong, without searching the interwebs. Nick argues (apologies if I’m misrepresenting you!): "I believe our main motivation for separating it out was the fact that even though TargetScopeError is a compile-time error, the affected code is syntactically fine - there are just issues with unambiguously inferring the intended read/write location for the affected target names. (Subclassing SyntaxError is then a pragmatic concession to the fact that "SyntaxError" also de facto means "CompilationError”)” Serhiy points out that we have IndentationError and TabError subclasses of SyntaxError, but those feel different to me because the exception names themselves are clear and descriptive, and lead to obvious actionable remedies. Guido then suggests we take the discussion here, thus this email. It would be a very minor update to the PEP, but I think it’s useful to resolve before the last push for PEP 572 implementation gets completed. Rather than just a vote, if you have a rationale for one over the other, I’d love to hear it. Feel free to weigh in here or on the issue. Cheers, -Barry

What is a public API?
by Serhiy Storchaka 09 Aug '19

09 Aug '19

I thought that the name in a module is in the public interface if: * It doesn't start with an underscore and the module does not have __all__. * It is included in the module's __all__ list. * It is explicitly documented as a part of the public interface. help() uses more complex rules, but it believes __all__ if it defined. But seems there are different views on this. * Raymond suggested to add an underscore the two dozens of names in the calendar module not included in __all__. https://bugs.python.org/issue28292#msg347758 I do not like this idea, because it looks like a code churn and makes the code less readable. * Gregory suggests to document codecs.escape_decode() despite it is not included in __all__. https://bugs.python.org/issue30588 I do not like this idea, because this function always was internal, its only purpose was implementing the "string-escape" codec which was removed in Python 3 (for reasons). In Python 3 it is only used for supporting the old pickle protocol 0. Could we strictly define what is considered a public module interface in Python?

Core review is needed by bpo-34788
by Sasha Pavlyuk 09 Aug '19

Hello 2019-06-03 I have created PR https://github.com/python/cpython/pull/13772 , which adds IPv6 scoped addresses support to ipaddress module. It is very critical to everyone, who is dealing with IPv6 networking. For example, in salt project they use patched module. So, it would be very nice to have my changes merged and avoid such a workarounds. Pull request passed review, but stopped at core review stage. I wrote reminder comment at bugtracker without any result, also I can not reach pmoody (a maintainer of ipaddress module). Here is link to the bug - https://bugs.python.org/issue34788. Please, pay attention to this issue. KR Oleksandr Pavliuk

Can someone please finish merging GH-13482?
by Tim Peters 08 Aug '19

https://github.com/python/cpython/pull/13482 is a simple doc change for difflib, which I approved some months ago. But I don't know the current workflow well enough to finish it myself. Like: - Does something special need to be done for doc changes? - Since this is a 1st-time contributor, does it need a change to the ACKS file? - Anything else? I'm sure this is all obvious after you've done it once, but I haven't. So I'll watch and do it myself next time ;-)
