Peter Inglesby added the comment: I can reproduce it reliably.
I ran ./configure with --with-pydebug. I'm not using NFS, and I'm not aware of anything else unusual about my filesystem. The fact that a timestamp overflows in the failing test is a red herring -- the following also fails, with os.stat raising FileNotFoundError: def test_without_timestamp_overflow(self): sys.path.insert(0, os.curdir) try: source = TESTFN + ".py" compiled = importlib.util.cache_from_source(source) with open(source, 'w') as f: pass __import__(TESTFN) os.stat(compiled) finally: del sys.path[0] remove_files(TESTFN) I've verified that TESTFN does get imported by writing 'print("hello")' to the source file. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26583> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
