Failing pytest tests under Python 3.13

[mrbean-bremen]

Found this after adding more pytest tests to the UI in connection with #1096. The pytest-specific tests for testing the module fixture (fs_module) fail with a lot of internal errors under macOS and Python 3.13:

For now, I've excluded the tests for this combination, but they have to be fixed.

[jcfp]

I'm seeing a very similar failure in the same test in the Debian package, reported in the distribution's bug tracker as bug #1090285.

With the CI running on Debian's Gitlab instance, for reasons unknown the testsuite completes without error during both the regular package build and the autopkgtest, but reliably fails the package build done as part of the reproducibility test (reprotest) with both 5.7.1 and 5.7.3 (test names in the pipeline overview link to the full logs).

Debian is in the process of moving from Python 3.12 to 3.13, so all packages currently build for and run tests with both; the error is only ever triggered with 3.13.

Log excerpt from 5.7.3

Thanks @jcfp - I will see what I can find out. Looks like this is not only a macOS problem...

[mrbean-bremen]

@jcfp - can you please check if it works for you with the main branch? The tests failing in the CI for macOS are passing now, but I don't know if the fix also helps in your environment.

LGTM 👍🏻
