Thanks @anntzer for reporting this.

The GitHub action succeeds if it's able to upload any wheels, it doesn't fail if some of the wheels fail to build. I have to not rely on the green check mark, but manually check that all the files are there.

It looks like GitHub runners don't have Python 13 on their Windows runners: actions/runner-images#11330
I don't know how to solve for this issue right now.

The two wheels missing for Linux are because some packages don't come pre-installed for Python >=12 (though this wasn't a problem for the previous release, where there is a Python 12 wheel?). I'm building those two wheels now, I expect this to complete successfully: https://github.com/DIPlib/diplib/actions/runs/13014880046/job/36301450318

Edit: second try: https://github.com/DIPlib/diplib/actions/runs/13015110153

Edit: a new version of wheel metadata is causing a lot of trouble. I find lots of bug reports online because of this, but no solutions that work for me. I'm using the latest packages to make the wheels, and the latest twine, but it keeps complaining about "Invalid distribution metadata: unrecognized or malformed field 'license-file'".

[anntzer]

Regarding twine: does force-upgrading packaging help? (python -m pip install -U packaging just before or after

diplib/.github/workflows/deploy.yml

Line 14 in 93481a1

run: python3 -m pip install twine

(and likewise for the other OSes) as suggested in pypa/twine#1216)

I tried that, didn’t change anything.

We’re on the latest version of twine, packaging, setuptools and wheel. Maybe there’s some other package that needs to be updated?

Even when setting license_files=['LICENSE.txt], I get a line License-File: LICENSE.txt in the METADATA file in the wheel. License-File is obsolete, we're supposed to use License-Files (plural). I don't know why setuptools is doing this. When I set it to an empty array, there's no License-File entry:

diplib/pydip/setup/setup.py.in

Line 43 in bb8cd0c

license_files=[], # Leaving this empty makes it so that there's no license-file entry in the METADATA file, which causes twine to balk.

Hopefully the wheels upload this time.

... of course now there's no LICENSE.TXT file in the wheel, but I at this point I don't care about that any more.

[crisluengo]

Yes, that worked! The Linux wheels are now all available on PyPI.

Still missing is the wheel for Windows and Python 3.13. Maybe there's a way to install this version of Python?

[anntzer]

Normally you can use the setup-python action (https://github.com/actions/setup-python); see https://github.com/matplotlib/mplcairo/blob/main/.github/workflows/build.yml for a personal example.

[crisluengo]

Thank you, that worked.

I have not modified the deploy script in the master branch for this last Windows issue, in the hope that GitHub will have Python 3.13 installed by default by the next time we roll a release. We'll have to double-check that this is indeed the case.
