[issue17437] Difference between open and codecs.open
by Giampaolo Rodola' 16 Nov '20

16 Nov '20

New submission from Giampaolo Rodola': In Python 2 the distinction between open() and codes.open() was clear because 'encoding' and 'errors' args were provided by codecs.open only. This is no longer the case in Python 3 since both args are provided also by open(). I'm probably missing something but regardless I think codecs.open doc [1] should be more clear as to when and why (say) codecs.open(file, encoding='utf8', errors='ignore') should be preferred over open(file, encoding='utf8', errors='ignore').

[issue27119] `compile` doesn't compile into an AST object as specified
by Franklin? Lee 15 Nov '20

15 Nov '20

New submission from Franklin? Lee: >From `compile`'s doc: "Compile the source into a code or AST object." The docs don't say how to compile into an AST object with `compile`, though. As it says later: "If you want to parse Python code into its AST representation, see ast.parse()." I checked 3.4-3.2, 3.0, 2.7, and 2.6. Versions before 3.4, and version 2.6, are missing the `ast.parse` line, but still have the first line. ---------- assignee: docs@python components: Documentation messages: 266311 nosy: docs@python, leewz priority: normal severity: normal status: open title: `compile` doesn't compile into an AST object as specified type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue27119> _______________________________________

[issue25006] List pybind11 binding generator
by Wenzel Jakob 09 Nov '20

09 Nov '20

New submission from Wenzel Jakob: Hi, over the last few months, I've been developing a library ("pybind11") for creating Python bindings of C++ code. It is similar in spirit to Boost.Python but uses a very different minimalist approach. It would be fantastic to get this library listed here: https://docs.python.org/3/faq/extending.html The purpose of this ticket is that somebody with permissions might add it to this page. pybind11 is here: https://github.com/wjakob/pybind11 Please let me know if you need any additional information. Thank you, Wenzel ---------- assignee: docs@python components: Documentation messages: 249865 nosy: docs@python, wenzel priority: normal severity: normal status: open title: List pybind11 binding generator type: enhancement versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue25006> _______________________________________

[issue14003] __self__ on built-in functions is not as documented
by Роман Донченко 08 Nov '20

New submission from Роман Донченко <DXDragon(a)yandex.ru>: The language reference says this in section 3.2: ~ Built-in functions A built-in function object is a wrapper around a C function. Examples of built-in functions are len() and math.sin() <...> Special read-only attributes: <...> __self__ is set to None (but see the next item) <...>. ~ That is not the case: ActivePython 3.2.2.3 (ActiveState Software Inc.) based on Python 3.2.2 (default, Sep 8 2011, 10:55:13) [MSC v.1500 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> len.__self__ <module 'builtins' (built-in)> >>> open.__self__ <module 'io' (built-in)> >>> import math >>> math.sin.__self__ <module 'math' (built-in)> ---------- assignee: docs@python components: Documentation messages: 153287 nosy: SpecLad, docs@python priority: normal severity: normal status: open title: __self__ on built-in functions is not as documented type: behavior versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue14003> _______________________________________

[issue25821] Documentation for threading.enumerate / threading.Thread.is_alive is contradictory.
by Anthony Green 08 Nov '20

08 Nov '20

New submission from Anthony Green: The documentation at https://docs.python.org/3/library/threading.html#threading.Thread.is_alive relates: > The module function enumerate() returns a list of all alive threads. The documentation at https://docs.python.org/3/library/threading.html#threading.enumerate relates: > Return a list of all Thread objects currently alive. The list includes daemonic threads, dummy thread objects created by current_thread(), and the main thread. This is a contradiction, since if the main thread has stopped, is_alive(main_thread) will return False, but it will still be included in the list returned by threading.enumerate. Note that this is not a TOCTTOU issue. The issue is that enumerate actually includes "all alive threads, plus one [or more? I can't tell from the code] other[s]." ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue25821> _______________________________________

[issue15693] expose glossary link on hover
by Chris Jerdonek 07 Nov '20

07 Nov '20

New submission from Chris Jerdonek: It would be nice if hovering over the right side of the header to a glossary entry would expose a link in the same way that it does for function definitions, etc. http://docs.python.org/dev/glossary.html#glossary Otherwise, there doesn't seem to be a convenient way to get a direct link to a glossary entry. I'm not sure if this issue should also be filed with Sphinx. ---------- assignee: docs@python components: Documentation messages: 168388 nosy: cjerdonek, docs@python priority: normal severity: normal status: open title: expose glossary link on hover type: enhancement versions: Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15693> _______________________________________

[issue16834] ioctl mutate_flag behavior in regard to the buffer size limit
by Yuval Weinbaum 07 Nov '20

07 Nov '20

New submission from Yuval Weinbaum: In fcntl module, the documentation states the following regarding the mutate_flag in ioctl method: *** If it is false, the buffer’s mutability is ignored and behaviour is as for a read-only buffer, except that the 1024 byte limit mentioned above is avoided – so long as the buffer you pass is as least as long as what the operating system wants to put there, things should work. *** However, looking at the code (fcntlmodule.c) it seems that the 1024 bytes limitation is avoided when the mutate_flag is set to True (the opposite of what is stated in the doc). ---------- assignee: docs@python components: Documentation messages: 178732 nosy: Yuval.Weinbaum, docs@python priority: normal severity: normal status: open title: ioctl mutate_flag behavior in regard to the buffer size limit versions: Python 2.6 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue16834> _______________________________________
