STINNER Victor added the comment: Oh cool, my bisect tool identified the bug!
haypo@selma$ ./python -m test.bisect -o bisect test_warnings test_warnings (...) Tests (1): * test.test_warnings._WarningsTests.test_showwarnmsg_missing (...) Bisection completed in 14 iterations and 0:00:14 So the bug is that test_showwarnmsg_missing() removes the warnings._showwarnmsg attribute, but don't restore it. https://github.com/python/cpython/pull/2504 fixes the issue. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30812> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
