Support for Python 3.13 on Windows

[davidbrochart]

I'm trying to publish wheeld for pycrdt on Windows for Python 3.13 and I get an error suggesting that Python 3.13 is not found

🐍 Found CPython 3.8 at C:\hostedtoolcache\windows\Python\3.8.10\x64\python.exe, CPython 3.9 at C:\hostedtoolcache\windows\Python\3.9.13\x64\python.exe, CPython 3.10 at C:\hostedtoolcache\windows\Python\3.10.11\x64\python.exe, CPython 3.11 at C:\hostedtoolcache\windows\Python\3.11.9\x64\python.exe, CPython 3.12 at C:\hostedtoolcache\windows\Python\3.12.6\x64\python.exe, CPython 3.13
...
  = note: LINK : fatal error LNK1181: cannot open input file 'python313.lib'

I'm not sure I should report here, or if I'm doing something wrong on my side?

Python 3.13 isn't installed by default in Actions runner yet: https://github.com/actions/runner-images/blob/main/images/windows/Windows2022-Readme.md#python

You can install it before building using setup-python action manually for the moment.

@messense Perhaps I'm doing something wrong, but even after setup-python explicitly adds python 3.13 for all my platforms, maturin doesn't seem to find it and stops at python 3.12. Some links for reference:

Thanks for your time!

@JacobCallahan See PyO3/maturin#2248

for now you can pass the list of python versions manually via -i, for example https://github.com/jupyter-server/pycrdt/actions/runs/11251137381/workflow#L27

@messense very nice! Do you know how soon that will be available in the action, if soon, then I might just hold off instead of doing a temporary workaround.

@messense i tried using maturin-action:main for a run to see if the change you linked would help, but it still doesn't look to have detected py3.13

fyi adding setup-python doesn't fix failing CI on win i686 for 3.13:

fwiw, we got python 3.13 to work on windows: oconnor663/blake3-py#46
