I haven't seen pp3 used anywhere by pypy. Do you know where it is used?

pp3 is the generic PyPy 3 tag, it isn't used in many places. I can't remember any example where it's used from the top of my mind.
But actually, we probably want the tag with minor version here (eg. pp310). I just noticed that given the code doesn't handle it right now, it doesn't think pp310-none-any is a compatible tag on 3.10 PyPy.

That comes specifically from PyPy and @mattip , so I would not want to change that logic without his approval.

pp3-none-any is a valid complete tag for PyPy, see #466. This is used in projects like vmprof that have a PyPy-specific pure python implementation for PyPy but need a c-extension implementation for CPython [1].
It is unclear what the correct value should be for an "interpreter_tag" function. Is the intention
- a "minimal" PEP 425 python tag for a pure-python package compatible with any version of python3? Then for CPython this should return
py3, and for pypy it could return eitherpy3orpp3(if the pure-python code should only be used on PyPy) - a "versioned" PEP 425 python tag for a pure-python package that cannot be used on lower versions of python? Then for both CPython 3.9 and PyPy 3.9 this should return
py39 - a "versioned" PEP 425 python tag for a non-pure-python package? Then for CPython 3.9 this should return
cp39and for PyPypp39.
Without a docstring or any context where this should be used, it is difficult to figure out the author's intention. The name interpreter_tag also does not help. I think it should be closer to python_tag since that is the language of PEP 425.
[1] Note that the project has not released such a tagged wheel, since the project has not had a release since pip/wheel with #466 was merged and released.

As there are still open questions on the issue and there's a merge conflict I'm going to remove myself as a reviewer until those two things can be addressed to help keep my review queue clean. |
Closes #612
