cache.mkdir() in a session-level fixture, in combination with xdist, sometimes results in OSError: [Errno 39] Directory not empty when pytest tries to rename the cache directory.
This is a regression in 8.2.0, most likely introduced by #12168 / #12167
On 8.1.x cache.mkdir() works fine in the same case.
In conftest.py:
@pytest.fixture(scope='session')
def my_fixture(request):
return request.config.cache.mkdir('testdir')In test_tests.py:
@pytest.mark.parametrize('n', list((n,) for n in range(42)))
def test_test(my_fixture, n):
passRunning with pytest -n auto results in:
self = PosixPath('/home/runner/work/pytest-cache-race/pytest-cache-race/.tox/python/pytest-cache-files-8ulls0nm')
target = PosixPath('/home/runner/work/pytest-cache-race/pytest-cache-race/.tox/python/.pytest_cache')
def rename(self, target):
