Bug Report: Python C library not compatible with C++2020
by Tang Tien Wei Keith 16 Jan '20

16 Jan '20

The Python library will not compile with a C++2020 compiler because the code uses the reserved "module" keyword For example, in warnings.h, we have the following code: #ifndef Py_LIMITED_API PyAPI_FUNC(int) PyErr_WarnExplicitObject( PyObject *category, PyObject *message, PyObject *filename, int lineno, PyObject *module, PyObject *registry); In modsupport.h we have the following code: PyAPI_FUNC(int) PyModule_ExecDef(PyObject *module, PyModuleDef *def); We can fix this by using a different identifier, for example "pyModule" instead of "module" This e-mail and any attachments are only for the use of the intended recipient and may contain material that is confidential, privileged and/or protected by the Official Secrets Act.

[issue39348] wrong rst syntax in socket.rst
by Oz Tiram 16 Jan '20

16 Jan '20

New submission from Oz Tiram <nahumoz(a)gmail.com>: The code block for the isn't hightlighted: Changed in version 3.7: When SOCK_NONBLOCK or SOCK_CLOEXEC bit flags are applied to type they are cleared, and socket.type will not reflect them. They are still passed to the underlying system socket() call. Therefore:: sock = socket.socket( ... This is because the double colon is directly after the word Therefore. This fix is very simple: :attr:`socket.type` will not reflect them. They are still passed - to the underlying system `socket()` call. Therefore:: + to the underlying system `socket()` call. Therefore, + + :: sock = socket.socket( socket.AF_INET, ... I have prepared a PR for this. ---------- assignee: docs@python components: Documentation messages: 360086 nosy: Oz.Tiram, docs@python priority: normal severity: normal status: open title: wrong rst syntax in socket.rst versions: Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue39348> _______________________________________

[issue39222] unittest.mock.Mock.parent is broken or undocumented
by Florian Brucker 15 Jan '20

15 Jan '20

New submission from Florian Brucker <python-bugs(a)florianbrucker.de>: The "parent" attribute of unittest.mock.Mock is either broken or undocumented. For example, on Python 3.7.4: >>> from unittest.mock import Mock >>> m = Mock(x=1, parent=2) >>> m.x 1 >>> m.parent Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.7/unittest/mock.py", line 659, in __repr__ name = self._extract_mock_name() File "/usr/local/lib/python3.7/unittest/mock.py", line 638, in _extract_mock_name _name_list.append(_parent._mock_new_name + dot) AttributeError: 'int' object has no attribute '_mock_new_name' >>> parent = Mock() >>> child = Mock(parent=parent) >>> child.parent is parent False I stumbled upon this while trying to mock an object that has a "parent" attribute. >From the documentation I understand that mocks have built-in parents. However, the documentation never mentions the "parent" attribute specifically, so I always assumed that the built-in parent-child relationship was handled using private or name-mangled attributes. And since the "parent" attribute is not mentioned in the docs, I assumed I could set it by passing an additional kwarg to Mock. I would have expected one of the following, in order of personal preference: a) That a private or name-mangled attribute is used for the built-in parent-child relationship, so that I can mock objects which themselves have a "parent" attribute b) That the special meaning of the "parent" attribute is documented, and that trying to set it directly (via the constructor or via attribute assignment, and without going through attach_mock) triggers a warning. ---------- assignee: docs@python components: Documentation, Library (Lib) messages: 359348 nosy: docs@python, florian.brucker priority: normal severity: normal status: open title: unittest.mock.Mock.parent is broken or undocumented type: behavior versions: Python 3.6, Python 3.7 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue39222> _______________________________________

Small broken link on the docs.python.org page
by Nicholas Chen 13 Jan '20

13 Jan '20

Hey Python team! I’m noticing a broken link on the docs.python.org <http://docs.python.org/> page. The bottom of the page, regarding Sphinx, is broken: Clicking that Sphinx link leads to a 404 error. I believe the link should be updated to: https://pypi.org/project/Sphinx/ <https://pypi.org/project/Sphinx/> as referenced here: https://github.com/python/cpython/tree/master/Doc <https://github.com/python/cpython/tree/master/Doc> Thanks, Nick
