I'm stymied by a pytest-related bug. I thought it was a bug in a
particular pytest plugin (pytest-order), but it's now shown up in
another pytest plugin as well, so I wonder if either there's a bug in
pytest 8.x or something subtle has changed that requires a
modification to the plugins. I couldn't see anything obvious on the
pytest changelog page, and the error message itself is mysterious to
me. The bug does not show with pytest 7.4.4, so it is certainly
related to the new pytest version.

I wasn't able to pinpoint the cause yet, but I noticed that the failing sessions have "rootdir: /tmp" instead of the usual /tmp/autopkgtest-lxc.*/downtmp/autopkgtest_tmp/build

Hi Timo,

Oh, that is interesting! Good spot, thank you! I wonder whether
tmpdir is creating a weird location? BTW, this problem appears when
running autopkgtest under lxc. In my other package, the tests passed
when running under sbuild but not with autopkgtest under lxc, which
suggests that there's something weird about the lxc setup.

Best wishes,

Julian

Ah, I think you've hit the nail on the head!!

https://github.com/pytest-dev/pytest/issues/11781

And then pytest looks for any __init__.py file it can find, including
in unreadable directories...

Unfortunately, changing the argument from str(tmpdir) to
f"--rootdir={tmpdir}" caused my computer to crash (CPU usage went
through the roof until the computer became unresponsive) - clearly
there's something not quite right here yet!!

Best wishes,

Julian
