Musllinux wheels

CI request: build PEP 656-compliant "musllinux" wheels. This will allow easy installation in Alpine Docker images

Probably just me - you start out by saying 'CI request', and then end up talking about installation. Are you asking for us to setup a CI job for musllinux, or distribute wheels?

I read it as a request to add support for whatever-it-is to https://github.com/python-pillow/pillow-wheels/issues

Ok. The easiest way to do that would be to wait for multi-build/multibuild#430

I'm going to use the magic "Transfer issue" link on the right to move this issue over to pillow-wheels!

It's the future!!

My suggestion is to use CI to generate a musllinux wheel, then include it in the file-set during a Pillow release. I didn't realise there is a separate repository for building wheels for Pillow

Note: musllinux is a specification for an environment (specifically a set of expected C shared libraries, using the musl libc), not a Linux distribution. You can build and test a Pillow installation on Alpine or OpenWRT, but wheels generated on these distributions won't be musllinux-compliant without adding in non-expected shared libraries.

@EpicWink Sounds reasonable though I'm not sure how much traction this will get unless there is some massive need for these wheels … and if that is not the case, then I think we'd be open to accepting a PR to implement this for you.

There have been a few requests in the past, see e.g. python-pillow/Pillow#5292 (comment) for the most recent one.

These wheels have now been released as part of Pillow 9.1.0.
