[issue25509] PyImport_ImportModule inaccurately described

by Memeplex

New submission from Memeplex: The documentation (for 3.5) states that "[PyImport_ImportModule] is a simplified interface to PyImport_ImportModuleEx()" but the current implementation calls PyImport_Import instead, which is a higher level interface that takes into account import hooks. Older versions of PyImport_ImportModule (say 2.0) did call PyImport_ImportModuleEx, but that's no longer the case. The PyImport_Import* naming convention got a bit messy with the years and maybe I'm not understanding the intention quite well, but it seems to me that the documentation is outdated and that there is a change in semantics for PyImport_ImportModule. ---------- assignee: docs@python components: Documentation messages: 253674 nosy: docs@python, memeplex priority: normal severity: normal status: open title: PyImport_ImportModule inaccurately described versions: Python 3.5 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue25509> _______________________________________

[issue9499] Python C/API Execution namespace undocumented. (patch included)

by Campbell Barton

New submission from Campbell Barton <ideasman42(a)gmail.com>: Some parts of the python api expect __main__ module dictionary to be the namespace when executing a script, this is true when running a python script from the python binary but NOT true when running a compiled script from the C/API which can lead to bugs which are not easy to solve unless the C/API author knows this. ---------- assignee: docs@python components: Documentation files: doc_py3_main_mod.diff keywords: patch messages: 112706 nosy: docs@python, ideasman42 priority: normal severity: normal status: open title: Python C/API Execution namespace undocumented.

[issue12174] Multiprocessing logging levels unclear

by JJeffries

New submission from JJeffries <jamesjeffries1(a)gmail.com>: It is unclear without reference to the logging module where the multiprocessing logging levels fit in the normal logging provided by the logging module, even though it says above the table "The table below illustrates where theses fit in the normal level hierarchy. +----------------+----------------+ | Level | Numeric value | +================+================+ | ``SUBWARNING`` | 25 | +----------------+----------------+ | ``SUBDEBUG`` | 5 | +----------------+----------------+" I propose adding further values from the logging module for clarification. ---------- assignee: docs@python components: Documentation messages: 136839 nosy: JJeffries, docs@python priority: normal severity: normal status: open title: Multiprocessing logging levels unclear versions: Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12174> _______________________________________

[issue13047] imp.find_module("") and imp.find_module(".")

by Arfrever Frehtes Taifersar Arahesis

New submission from Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA(a)GMail.Com>: It's undocumented that imp.find_module("") and imp.find_module(".") try to find __init__.py. There is also a small difference in behavior between them. sys.path by default contains "" as the first element, which is sufficient for imp.find_module("."), but not for imp.find_module(""): $ mkdir /tmp/imp_tests $ cd /tmp/imp_tests $ touch __init__.py $ python3.3 -c 'import imp, sys; print(repr(sys.path[0])); print(imp.find_module("."))' '' (None, '.', ('', '', 5)) $ python3.3 -c 'import imp, sys; print(repr(sys.path[0])); print(imp.find_module(""))' '' Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named '' If sys.path contains path (e.g. "." or absolute path) to directory with __init__.py file, then imp.find_module("") will succeed: $ PYTHONPATH="." python3.3 -c 'import imp, sys; print(repr(sys.path[0:2])); print(imp.find_module("."))' ['', '/tmp/imp_tests'] (None, '.', ('', '', 5)) $ PYTHONPATH="." python3.3 -c 'import imp, sys; print(repr(sys.path[0:2])); print(imp.find_module(""))' ['', '/tmp/imp_tests'] (None, '/tmp/imp_tests/', ('', '', 5)) $ python3.3 -c 'import imp, sys; sys.path.insert(1, "."); print(repr(sys.path[0:2])); print(imp.find_module("."))' ['', '.'] (None, '.', ('', '', 5)) $ python3.3 -c 'import imp, sys; sys.path.insert(1, "."); print(repr(sys.path[0:2])); print(imp.find_module(""))' ['', '.'] (None, './', ('', '', 5)) I think that imp.find_module(".") and imp.find_module("") should have the same behavior, and this behavior should be documented. ---------- assignee: docs@python components: Documentation, Interpreter Core messages: 144531 nosy: Arfrever, docs@python priority: normal severity: normal status: open title: imp.find_module("") and imp.find_module(".") versions: Python 2.7, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue13047> _______________________________________

[issue14979] pdb: Link to source

by anatoly techtonik

New submission from anatoly techtonik <techtonik(a)gmail.com>: http://docs.python.org/library/pdb.html#pdb.Pdb Documentation for pdb says: "The debugger is extensible — it is actually defined as the class Pdb. This is currently undocumented but easily understood by reading the source." There should a link to the source. ---------- assignee: docs@python components: Documentation, Library (Lib) messages: 162074 nosy: docs@python, techtonik priority: normal severity: normal status: open title: pdb: Link to source _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue14979> _______________________________________

[issue19438] Where is NoneType in Python 3?

by mpb

New submission from mpb: types.NoneType seems to have disappeared in Python 3. This is probably intentional, but I cannot figure out how to test if a variable is of type NoneType in Python 3. Specifically, I want to write: assert type (v) in ( bytes, types.NoneType ) Yes, I could write: assert v is None or type (v) is bytes But the first assert statement is easier to read (IMO). Here are links to various Python 3 documentation about None: [1] http://docs.python.org/3/library/stdtypes.html#index-2 [2] http://docs.python.org/3/library/constants.html#None Link [2] says: "None The sole value of the type NoneType." However, NoneType is not listed in the Python 3 documentation index. (As compared with the Python 2 index, where NoneType is listed.) [3] http://docs.python.org/3/library/types.html If NoneType is gone in Python 3, mention of NoneType should probably be removed from link [2]. If NoneType is present in Python 3, the docs (presumably at least one of the above links, and hopefully also the index) should tell me how to use it. Here is another link: [4] http://docs.python.org/3/library/stdtypes.html#bltin-type-objects "The standard module types defines names for all standard built-in types." (Except <class 'NoneType'> ???) None is a built-in constant. It has a type. If None's type is not considered to be a "standard built-in type", then IMO this is surprising(!!) and should be documented somewhere (for example, at link [4], and possibly elsewhere as well.)

[issue20582] socket.getnameinfo() does not document flags

by Roy Smith

New submission from Roy Smith: http://docs.python.org/2/library/socket.html The description for getnameinfo() says, "... Depending on the settings of flags, the result can contain a fully-qualified domain name or numeric address representation in host.", but does not say what to pass for flags to get those behaviors. ---------- assignee: docs@python components: Documentation messages: 210838 nosy: docs@python, roysmith priority: normal severity: normal status: open title: socket.getnameinfo() does not document flags versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue20582> _______________________________________

[issue24757] Installing Py on Windows: Need to restart or logout for path to be added

by John Palermo

New submission from John Palermo: Something I suppose many new users could stumble over: After installing Python and trying out "pip" or "python" on the command line nothing is found. You have to re-start Windows or re-log into your account. I suggest adding this information to the documentation here https://docs.python.org/2/using/windows.html#installing-python and also adding it to the Windows installer description for the "add Python to your path" option. ---------- assignee: docs@python components: Documentation messages: 247688 nosy: John Palermo, docs@python priority: normal severity: normal status: open title: Installing Py on Windows: Need to restart or logout for path to be added type: enhancement versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue24757> _______________________________________

[issue18280] Documentation is too personalized

by Serhiy Storchaka

New submission from Serhiy Storchaka: Some documentation files contain a number of I/my/me. Looks like they grew from personal modules and personal articles. Perhaps the official documentation needs more depersonalized style. Here is full list of such files: Doc/c-api/exceptions.rst Doc/c-api/long.rst Doc/distutils/builtdist.rst Doc/extending/extending.rst Doc/extending/windows.rst Doc/howto/argparse.rst Doc/howto/curses.rst Doc/howto/functional.rst Doc/howto/regex.rst Doc/howto/sockets.rst Doc/howto/urllib2.rst Doc/install/index.rst Doc/library/audioop.rst Doc/library/ctypes.rst Doc/library/doctest.rst Doc/library/heapq.rst Doc/library/numbers.rst Doc/library/ossaudiodev.rst Doc/library/tk.rst Doc/library/unittest.mock-examples.rst Doc/library/unittest.mock.rst Doc/reference/introduction.rst Doc/tutorial/classes.rst The list doesn't include FAQs where it may be appropriate and whatsnew files. Andrew Kuchling recently has fixed Doc/howto/unicode.rst for this issue (as part of issue4153). ---------- assignee: docs@python components: Documentation messages: 191636 nosy: akuchling, docs@python, eric.araujo, ezio.melotti, georg.brandl, serhiy.storchaka priority: normal severity: normal status: open title: Documentation is too personalized versions: Python 2.7, Python 3.3, Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue18280> _______________________________________
