[issue37387] test_compileall fails randomly on Windows when tests are run in parallel

Eryk Sun added the comment: > I don't know enough about when and why CPython decides to > replace .pyc files It's straight-forward in the case of py_compile.compile(): >>> pyc = py_compile.compile('test.py') >>> f = open(pyc) >>> try: py_compile.compile('test.py') ... except

[issue43969] "bad magic number" when Python 2's pyc file exists without py file

Mitchell Hentges added the comment: Looking closer into this, it appears that Python 3 will still try to load non-__pycache__ `.pyc` files. Perhaps I'm missing context, but aren't those only supposed by to written and read by Python 2? Location where `pyc` loader is registered: https://gith

[issue43980] netrc module looks for .netrc even on Windows where the convention is _netrc

New submission from Jerry Heiselman : The netrc library defaults to looking for the .netrc file in the user's home directory. On Windows, this file is conventionally named _netrc. While one could pass the correct path to the library, the conventionally correct path should be used on all suppo

Steve Dower added the comment: Any reason this couldn't be in sitecustomize.py? Either by poking values into sysconfig directly (for back-compat) or we train sysconfig to look inside sitecustomize for a well-known name. -- nosy: +steve.dower ___ P

[issue42904] get_type_hints does not provide localns for classes

Larry Hastings added the comment: Thank you for your in-depth and thoughtful reply! I think that APIs should behave in a predictable way. So, for my use case, I tell the user that I'm passing "globals" and "locals" into eval()--and I think I'd have to have a *very* compelling reason to swap

Steven D'Aprano added the comment: This is a behaviour change not a simple bug fix. 3.6 through 3.9 are all in feature-freeze, and we're days away from the same for 3.10. Not that I don't believe you about the _netrc convention on Windows, but do you have a link to a reliable source document
