FileNotFoundError with v2.21.0

[cbrnr]

Description

When running one of my tests with cibuildwheel v2.21.0, I get a FileNotFoundError for one of my package files (I'm using setuptools-scm, and this file is a data file):

https://github.com/cbrnr/sleepecg/actions/runs/10880385421/job/30187081612#step:3:498

The previous v2.20.0 worked with the same configuration:

It may be related to an updated method of coping files to the container.
#2004
So maybe #2007 will also solve this.

[cbrnr]

Yeah, I saw this issue, but I didn't have any file permission messages in the log. However, it might still be related and I'm happy to test whenever that fix lands.

I remember File not found error when I do not have permissions to access the file. But I may be wrong.

I had a look and I'm doubtful that it's a permission problem, because the file that's not found in the backtrace is in the test venv, which should have been installed by pip running in the container.

It might simply be that your test dependencies have updated since you last tried a build. Did you check that it still works on cibuildwheel==2.20.0 ?

[cbrnr]

Yes, I've tried the exact same configuration with v2.20.0, it's linked in the first post.

[joerick]

Thanks. I don't understand the issue! but I've confirmed that #2007 fixes it by doing

uvx --from https://github.com/mayeut/cibuildwheel/archive/refs/heads/use-tar.zip cibuildwheel --platform linux .

So I guess it is a permissions issue. Maybe @Czaki knows more!

[Czaki]

@cbrnr could you check the latest release?

[cbrnr]

Yes, v2.21.1 fixes the issue (cbrnr/sleepecg#236)! Thanks for the quick fix everyone! 🎉
