add osx-arm64 variant config file

[wolfv]

I didn't have a chance to test this yet -- any idea on how to test this easily?

[mxschmitt]

I think no way to test it easily, but we release a new Playwright version shortly, so we can then see if it works!

[mxschmitt]

We have build workflows configured, you. could try to add it there as well:

playwright-python/.github/workflows/ci.yml

Can you actually publish Apple Silicon from an amd mac?

[wolfv]

Does the pip setup.py download any binaries from the internet? We might have to tell it to grab the appropriate ones for osx-arm64 as otherwise it migth think that it's still on osx-64.

All the osx-arm64 packages on conda-forge are built by cross-compiling so it should work fine from the "conda-side".

[wolfv]

Just FYI cross compiling with conda-build works by putting the dependencies for the build platforms (osx-64) that need to run during build in the build section of the recipe, and the ones that are linked against in the host section (that section will use packages from the osx-arm64 architecture.

Yes it does.

By default it builds wheels containing the driver for the current platform/architecture. See here. You can pass --all and then it builds all the wheels. I think as of today the issue is that it builds only the current platform/arch by default, so we require conda to run on this specific arch to be able to get the corresponding wheel while publishing the conda package.

We might have to tell it to grab the appropriate ones for osx-arm64 as otherwise it might think that it's still on osx-64.

Yes I think thats what we need to do. And then tell conda to invoke setup.py per platform.

Closing as per above. If anyone wants to revisit this in the future, feel free to create a new PR, thanks!

[mxschmitt]

Actually let me re-open, things have changed, GitHub now has M1 runners, do you mind adding this to the matrix? Then it should work I believe: https://github.blog/2023-10-02-introducing-the-new-apple-silicon-powered-m1-macos-larger-runner-for-github-actions/

Landed in #1745.

[mxschmitt]

This should be fixed as part of v1.43.0

[wolfv]

Thanks!
