release wheel for 3.10

[ianhi]

Minimal, reproducible code sample, a copy-pastable example if possible

mamba create -n test python=3.10
pip install numcodecs

Problem description

Above code spends some time building the wheel. Which may fail on some systems and also slows down install times. It would be great to bump CI python versions and release the new wheels.

Version and installation information

Please provide the following:

• Value of numcodecs.__version__ 0.9.1
• Version of Python interpreter 3.10
• Operating system (Linux/Windows/Mac) linux
• How NumCodecs was installed (e.g., "using pip into virtual environment", or "using conda"): pip

I think conda-forge has built for 3.10 already, if that will do.

I think conda-forge has built for 3.10 already, if that will do.

That's a good workaround - but I expect that there will be people who use pip primarily who will also run into this. e.g. i ran into this when doing pip install of different pacakge and it caught me off gaurd. No rush from me to fix, just wanted to bring it up

[martindurant]

Sure, we need to update the release too.

We build wheels with cibuildwheel in this GH Action. AFAICT cibuildwheel already supports Python 3.10. So that should just work. Just need to update the version here.

Currently CI doesn't cover Python 3.10. So adding that would be good to do.

If someone would like to do a PR to add Python 3.10, that would be a good first step towards addressing this. Not expecting any major issues there, but if they come happy to discuss. @ianhi would you be interested in giving this a try? 🙂

cibuildwheel already supports Python 3.10

Yes, only if it is up to date

[jakirkham]

Good point. Added to the comment above

This is one of the remaining not-on-3.10 yet wheels pyodide pyodide/pyodide#978. Do you still support Python 2? If so, then bumping to cibuildwheel 2.3.1 will drop 2.7 & 3.5 wheels - which is probably a good idea, since the only supported way to make them today is to use manylinux1, which is past EOL and hanging on by a thread. But you can split the job in two and use old cibuildwheel for old Python versions if that's the case. Otherwise, it should be a pretty simple bump.

Excellent, no Python <3.6 support, so should be a simple version bump. If you use our Action, you can even have GitHub Dependabot update this regularly for you.

Minor request, could you please remove the <4 from your Python requires? It causes issues for locking packages managers, and is discouraged. See https://iscinumpy.dev/post/bound-version-constraints/, https://discuss.python.org/t/requires-python-upper-limits, and cjolowicz/cookiecutter-hypermodern-python#1154 for some context / issues related to this.

What would need to be done to set this up?

On a side note, would be curious to learn more about how Pyodide & Zarr are being used together. Opened issue ( zarr-developers/community#43 ) for discussion on this 🙂

We've now added Python 3.10 testing and enabled Python 3.10 wheel builds. All of this thanks to Henry's PR ( #309 ) 😀

Packages are not published yet, but think we are ready to do that next (assuming no other blockers)

[jakirkham]

Wheels are now available for testing under 0.10.0a2. Thanks @joshmoore for producing those 😄

Thanks @jakirkham - worked for me
