[issue15629] Run doctests in Doc/*.rst as part of regrtest
by Chris Jerdonek 24 Jun '19

24 Jun '19

New submission from Chris Jerdonek: This issue is to start running (at least some of) the doctests in the Doc/ folder's *.rst files as part of regrtest. We will need a whitelist mechanism to tell regrtest which files to process since currently many doctests are not runnable (e.g. some kind of "doctest-safe" marker that can go in a file as suggested by Nick).

[issue13286] PEP 3151 breaks backward compatibility: it should be documented
by STINNER Victor 13 May '19

13 May '19

New submission from STINNER Victor <victor.stinner(a)haypocalc.com>: The following example works on Python 2.7 and 3.2, but fails on Python 3.3: ----------- import errno import os try: os.rmdir("testdir") except: pass os.mkdir("testdir") try: try: os.mkdir("testdir") except IOError as exc: # If can't get proper access, then just forget about writing # the data. if exc.errno == errno.EACCES: pass else: raise except OSError as exc: # Probably another Python process already created the dir. if exc.errno == errno.EEXIST: pass else: raise except Exception: print("PEP 3151 broke backward compatibility on such pattern!") ----------- I noticed the problem while reading the changeset e4d44c2e8e81. ---------- assignee: docs@python components: Documentation messages: 146562 nosy: docs@python, flox, haypo, pitrou priority: normal severity: normal status: open title: PEP 3151 breaks backward compatibility: it should be documented versions: Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue13286> _______________________________________

[issue10536] Enhancements to gettext docs
by Éric Araujo 09 May '19

09 May '19

New submission from Éric Araujo <merwok(a)netwok.org>: A patch made for #2504 revealed a bug in gettext.rst, and I’ve found a number of other things to change in the file. This is the first patch of a series of two or three. Barry, as the original author of the module and doc, I’d like your opinion on points 3, a, and b particularly. Patch is also uploaded to Rietveld for greater convenience: http://codereview.appspot.com/3333042/ (upload.py rocks) Summary: 1) Markup: Use modern class/method directives combo (yay DRY). Mark up variable parts in :file: constructs (e.g. :file:`{domain}.mo` will cause the HTML output to use var to indicate replaceable text). Also change some ``gettext`` to :program:`gettext` for consistency. 2) Fix a typo in lngettext doc (originally included in patch by Franz Glasner for #2504). 3) I had started to remove information about private attributes (_info, _charset), advertising public getter methods instead. Then I read the description of NullTranslations and realized the information was needed for subclasses. I’ve reverted my removals, but I still think the private attributes should be listed in a specific section for people writing subclasses and not in the rest of the text. If you’re okay, I’ll make a second patch. 4) Assorted wording changes, missing periods and hyphens, and other very small touch-ups: Turned a broken bare link into a working link with nice text; used the with statement in an example (we all love the with statement!); used two spaces after periods throughout (hello Fred Drake). Final note: lines have not been rewrapped, for diff clarity. When I commit part or all of this patch, I’ll make another commit to rewrap. Not addressed: a) The current docs is currently POSIX-specific. b) The docs take great care to explain that Unicode strings will be returned in different places, but this should not be so accented in 3.x docs IMO. I would just put a note somewhere near the top that all strings are str and remove the redundant sentences. Following that line of thought, I could group all l*gettext variants at the end of the list of methods, explaining that regular usage should just be happy with str objects and that l*gettext are available if people really want bytes. c) The file uses “built-in namespace” and “builtins namespace”, sometimes in neighbor paragraphs. :mod:`builtins` is not used, even in explanations of the install function/method. I don’t know if I should change that. d) Some capitalization patterns look strange to me: I have seen “I18N” and “L10N” in upper case nowhere else. Similarly, lower-case “id” looks stranger than “ID”. The latter is used for example in official GNU gettext docs. Am I going into foolish consistency territory or not? Thanks in advance for reviews and opinions. ---------- assignee: eric.araujo components: Documentation files: gettext-docs-1.diff keywords: needs review, patch messages: 122420 nosy: barry, docs@python, eric.araujo priority: normal severity: normal stage: patch review status: open title: Enhancements to gettext docs versions: Python 2.7, Python 3.1, Python 3.2 Added file: http://bugs.python.org/file19819/gettext-docs-1.diff _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10536> _______________________________________

[issue12188] PEP 7, C style: add ++ policy and explanation
by Terry J. Reedy 09 May '19

09 May '19

New submission from Terry J. Reedy <tjreedy(a)udel.edu>: In response to a discussion of a patch removing 'useless' post-increments, (which issue has apparently come up before) Guido posted "> Sorry to butt in here, but I agree with Eric that it was better > before. There is a common idiom, *pointer++ =<something>, and > whenever you see that you know that you are appending something to an > output buffer. Perhaps the most important idea here is that this > maintains the *invariant* "pointer points just after the last thing in > the buffer". Always maintaining the invariant is better than trying to > micro-optimize things so as to avoid updating dead values. The > compiler is better at that." A condensed version of the above added to PEP 7 would help new developers see the usage as local idiom rather than style bug. ---------- assignee: docs@python components: Documentation messages: 136991 nosy: docs@python, terry.reedy priority: normal severity: normal status: open title: PEP 7, C style: add ++ policy and explanation _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12188> _______________________________________

[issue10789] Lock.acquire documentation is misleading
by Jyrki Pulliainen 26 Apr '19

26 Apr '19

New submission from Jyrki Pulliainen <jyrki(a)dywypi.org>: In threading module, the Lock.acquire documentation is misleading. The signature suggests that the blocking can be given as a keyword argument but that would lead to an TypeError, as thread.lock.acquire does not accept keyword arguments. The signature in documentation should be formatted as in thread.lock.acquire. ---------- assignee: docs@python components: Documentation messages: 124861 nosy: Jyrki.Pulliainen, docs@python priority: normal severity: normal status: open title: Lock.acquire documentation is misleading versions: Python 2.7, Python 3.1 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10789> _______________________________________

[issue10048] urllib.request documentation confusing
by Antoine Pitrou 26 Apr '19

26 Apr '19

New submission from Antoine Pitrou <pitrou(a)free.fr>: The urllib.request documentation intermingles old 2.x urllib (FancyURLopener, etc.) with urllib2-inherited (*Handler, build_opener, etc.) primitives without making any distinction. This makes it rather confusing for the reader to figure out which ones to use. Ideally, the use of the old primitives should also be discouraged. ---------- assignee: docs@python components: Documentation messages: 118179 nosy: docs@python, orsenthil, pitrou priority: normal severity: normal stage: needs patch status: open title: urllib.request documentation confusing versions: Python 3.1, Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10048> _______________________________________

[issue16242] Pickle and __getattr__
by Joseph Fall 26 Apr '19

26 Apr '19

New submission from Joseph Fall: This report is to re-raise an old issue from 2009: http://bugs.python.org/issue5370 Although that issue is marked as "fixed", I disagree that it was ever "fixed", and spent an evil day tracking it down. Use Case: - take two 3rd party packages: django and django-crispy-forms - django, deep in its inner-workings, uses Pickle - django-cripsy-forms implements the _getattr__ method in one of it's classes - when you put the two together such that django pickles a form, the python interpreter goes into a tailspin in very sinister and hard-to-track-down ways (different behaviour in 2.5, 2.6, 2.7, as noted in issue5370, which includes a simple test case) The "resolution" for issue5370 was to add some documentation to Pickle. But I would argue this is insufficient - the implementer of django-crispy-forms would have no reason to ever look at the Pickle docs, and so is very likely to implement this bug (which s/he did). Perhaps, if this issue cannot be resolved in code, as suggested by gagenellina back in 2009, at least some documentation could be added to __getattr__ (and others) warning that these methods could potentially be called before __init__ (similar to the documentation added to Pickle)? I'd be happy to draft a small bit of documentation for this, although if someone can think of a way to simply resolve this in Pickle so it does not cause the issue in the first place, that seems to me ideal. A test case is included with issue5370 ---------- assignee: docs@python components: Documentation, Library (Lib) messages: 172993 nosy: docs@python, powderflask priority: normal severity: normal status: open title: Pickle and __getattr__ type: behavior versions: Python 2.6, Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue16242> _______________________________________

[issue12957] mmap.resize changes memory address of mmap'd region
by Michael Schurter 26 Apr '19

26 Apr '19

New submission from Michael Schurter <m(a)schmichael.com>: Since mmap.resize uses MREMAP_MAYMOVE on Linux, it would be nice to warn users that pointers into their memory mapped regions will be invalid after resizes. Linux's manpage offers the following explanation: "If the mapping is relocated, then absolute pointers into the old mapping location become invalid (offsets relative to the starting address of the mapping should be employed)." Since the only way I know of to use pointers into mmaps from pure Python is to use ctypes.<type>.from_buffer(<mmap>), perhaps clarification would be better in the ctypes docs. ---------- assignee: docs@python components: Documentation files: killctypes.py messages: 143845 nosy: docs@python, schmichael priority: normal severity: normal status: open title: mmap.resize changes memory address of mmap'd region type: feature request versions: Python 2.7 Added file: http://bugs.python.org/file23126/killctypes.py _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12957> _______________________________________
