[issue43549] Outdated descriptions for configuring valgrind.
by Xinmeng Xia April 2, 2021

April 2, 2021

New submission from Xinmeng Xia <xiaxm(a)smail.nju.edu.cn>: At line 12-20, cpython/Misc/README.valgrind, the descriptions are out of date. File "Objects/obmalloc.c" does not contain Py_USING_MEMORY_DEBUGGER any more since Python 3.6. The descriptions should be modified for Python 3.6-3.10 Attached line 12-20, cpython/Misc/README.valgrind: ================================================= If you don't want to read about the details of using Valgrind, there are still two things you must do to suppress the warnings. First, you must use a suppressions file. One is supplied in Misc/valgrind-python.supp. Second, you must do one of the following: * Uncomment Py_USING_MEMORY_DEBUGGER in Objects/obmalloc.c, then rebuild Python * Uncomment the lines in Misc/valgrind-python.supp that suppress the warnings for PyObject_Free and PyObject_Realloc ================================================= ---------- assignee: docs@python components: Documentation messages: 389052 nosy: docs@python, xxm priority: normal severity: normal status: open title: Outdated descriptions for configuring valgrind. type: behavior versions: Python 3.10, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue43549> _______________________________________

[issue43697] Importlib documentation does not cover how meta path finders should handle namespace packages
by Brett Cannon April 1, 2021

April 1, 2021

Brett Cannon <brett(a)python.org> added the comment: > What I've never really got clear in my mind is how dotted names get handled. Essentially: 1. Check if parent is imported; if not then import (working your way all the way back to the top if necessary) 2. Ask the sys.meta_path finders if they can handle the module 3. Use the loader from the spec 4. Add the imported module as an attribute on the parent If you start from https://github.com/python/cpython/blob/master/Lib/importlib/__init__.py#L108 you can see how it all works. The Python code is actually not that complicated, especially if you ignore all the old PEP 302 compatibility code 😉. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue43697> _______________________________________

[issue43697] Importlib documentation does not cover how meta path finders should handle namespace packages
by Paul Moore April 1, 2021

April 1, 2021

Paul Moore <p.f.moore(a)gmail.com> added the comment: > if they return a spec they can, if they don't then they can't What I've never really got clear in my mind is how dotted names get handled. But that's probably just a matter of needing to experiment a bit (I don't think it's particularly complicated, I just need to get a better feel for it). > https://docs.python.org/3/reference/import.html#namespace-packages Ouch. I'd completely missed how much there is in there. Sorry about that, I should have done my research. Thanks for the help. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue43697> _______________________________________

[issue43698] Use syntactically correct examples on abc package page
by Vladimir Ryabtsev April 1, 2021

April 1, 2021

New submission from Vladimir Ryabtsev <greatvovan(a)gmail.com>: There are code snippets on the package's page (https://docs.python.org/3.10/library/abc.html) like this: class C(ABC): @classmethod @abstractmethod def my_abstract_classmethod(cls, ...): ... Here, the author probably wanted to demonstrate that the method may have _any other arguments_ in addition to `cls`, but it makes the code not compilable: def my_abstract_classmethod(cls, ...): ^ SyntaxError: invalid syntax Additionally it uses the same Ellipsis as in the method's body (that is supposed to indicate a stub), which is confusing. I think that all code samples must be syntactically correct, so that if a reader copypastes them into their code editor they would work right away. I suggest to remove ellipsis in the argument lists everywhere on the page and replace them with one of the following: - sample parameters such as `a, b, c` or `my_arg1, my_arg2`, - `*args, **kwargs`, - nothing. ---------- assignee: docs@python components: Documentation messages: 390004 nosy: Vladimir Ryabtsev, docs@python priority: normal severity: normal status: open title: Use syntactically correct examples on abc package page type: compile error versions: Python 3.10, Python 3.8, Python 3.9 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue43698> _______________________________________
