Per the other thread-- https://mail.python.org/pipermail/python-dev/2018-July/154762.html this seems like a wrong statement of the problem as tests are properly cleaning up after themselves. The leading hypothesis is that unrelated Windows processes are delaying the deletion (e.g. virus scanners). --Chris > > This change converts the tests to use tempfile.mkstemp which gives a > different file every time from the system's temp area > > files: > M Lib/test/test_bz2.py > > diff --git a/Lib/test/test_bz2.py b/Lib/test/test_bz2.py > index 003497f28b16..e62729a5a2f8 100644 > --- a/Lib/test/test_bz2.py > +++ b/Lib/test/test_bz2.py > @@ -6,6 +6,7 @@ > import os > import pickle > import glob > +import tempfile > import pathlib > import random > import shutil > @@ -76,11 +77,14 @@ class BaseTest(unittest.TestCase): > BIG_DATA = bz2.compress(BIG_TEXT, compresslevel=1) > > def setUp(self): > - self.filename = support.TESTFN > + fd, self.filename = tempfile.mkstemp() > + os.close(fd) > > def tearDown(self): > - if os.path.isfile(self.filename): > + try: > os.unlink(self.filename) > + except FileNotFoundError: > + pass > > > class BZ2FileTest(BaseTest): > > _______________________________________________ > Python-checkins mailing list > [email protected] > https://mail.python.org/mailman/listinfo/python-checkins _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
