pytest: garbage cannot be removed [Errno 39]

[ayushjariyal]

I am using Python 3.9.20 and pytest 8.3.5. While running pytest, after all tests pass successfully, a long list of warnings appears.

Based on the output, it seems that the rm_rf function is unable to delete some directories because they are not empty.

More context on the failure needed

At first glance this looks incorrect

[ayushjariyal]

Discription:

• After running pytest, all tests pass successfully, but a long list of warnings appears. The warnings indicate that rm_rf failed to remove some directories because they are not empty.
• At first glance, this seems incorrect since pytest should be able to clean up temporary files after test execution.

Expected Behavior:

• pytest should clean up temporary directories after the tests finish running.
• No warning should appear unless a legitimate issue prevents deletion.

Actual Behavior:

- pytest fails to remove some directories and raises warnings.

• The directories are reported as "not empty", even though pytest should handle cleanup.

Please show some sort of reproducer, nothing we can do with a screenshot and a vague description of an issue which only seems to happen on your end.

Perhaps this might help: pytest already uses shutil.rmtree, which should handle empty directories just fine. It won't work however in a few cases:

• The current user does not have permission to remove them (it might happen if a test changes permissions for example).
• A process is keeping an open handle to a file in the temporary directory.

Those are some of the top of my head that could cause this, but there might be others.
