Vajrasky Kok added the comment: Okay, here is the problem. In Windows, you get DeprecationWarning if you pass bytes object to method such as os.lstat.
foo.py ====== import os os.lstat(b"C:\\Users\\vajrasky\\Code\\cpython\\python.bat") C:\Users\vajrasky\Code\cpython>python.bat -Wdefault foo.py foo.py:2: DeprecationWarning: The Windows bytes API has been deprecated, use Unicode filenames instead os.lstat(b"C:\\Users\\vajrasky\\Code\\cpython\\python.bat") The test that throws this error is this one: def test_rmtree_works_on_bytes(self): tmp = self.mkdtemp() victim = os.path.join(tmp, 'killme') os.mkdir(victim) write_file(os.path.join(victim, 'somefile'), 'foo') victim = os.fsencode(victim) self.assertIsInstance(victim, bytes) shutil.rmtree(victim) => This one calls os.lstat So I am not sure how to fix this problem. Disable the test for Windows? If we convert the path to Unicode then the test losses the meaning. ---------- versions: +Python 3.5 -Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20056> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
