Python 3.12 compatibility

[Zethson]

Hi,

my CI job with Python 3.12 fails because of:

Caused by: Failed to fetch wheel: blosc==1.11.1
Caused by: Failed to build: blosc==1.11.1
Caused by: Build backend failed to build wheel through build_wheel() with exit status: 1

This seems to be an issue with the sdist. I can compile from a git-checkout on the 1.11.1 tag, but get this failure building from the sdist (both pulling from pypi and if I make the sdist locally).

pip install git+https://github.com/blosc/[email protected]

also works for me.

[tacaswell]

The issues seems to be with the bundeled version of blosc, setting USE_SYSTEM_BLOSC=1 gets the sdist to build for me as well with py312.

[FrancescAlted]

Ok. It looks like a new release is needed soon. Thanks for the hint.

[Zethson]

@FrancescAlted apologies for pinging you here, but would you be able to make a release soon? Currently, all packages that depend on python-blosc are broken on Python 3.12.

Thank you very much!

[FrancescAlted]

Yes, this is long overdue. We have a lot of work in our plates lately, and not too much funding for everything. Anyway, if you are benefiting from Blosc ecosystem, Blosc developers will always be happier when people contribute to our continued efforts. Thank you!

[tacaswell]

I also think this is another symptom of the issues described in https://pypackaging-native.github.io and the sustainability issues of the pip/wheel distribution model.

There are packages for python-blosc on conda-forge (and as noted above it can be made to compile with py312, just not from the sdist without an extra env).
