[mgorny]

setuptools version

Python version

Many tests fail when running from 61.3.0 due to a missing file, e.g.:

________________________________ ERROR collecting setuptools/tests/config/test_apply_pyprojecttoml.py _________________________________
setuptools/tests/config/test_apply_pyprojecttoml.py:21: in <module>
    EXAMPLES = (Path(__file__).parent / "setupcfg_examples.txt").read_text()
/usr/lib/python3.10/pathlib.py:1132: in read_text
    with self.open(mode='r', encoding=encoding, errors=errors) as f:
/usr/lib/python3.10/pathlib.py:1117: in open
    return self._accessor.open(self, mode, buffering, encoding, errors,
E   FileNotFoundError: [Errno 2] No such file or directory: '/tmp/setuptools-61.3.0/setuptools/tests/config/setupcfg_examples.txt'

Expected behavior

Tests passing ;-).

Thanks @mgorny for reporting this.

The classic manifest error 😅, sorry for that. I will have a look tonight.
