After reading the PEP I realized it is much simpler. The test is for interrupts that occur at a low-level - and not for permission issues. The test is failing because there is a permission issue, not a missed interrupt issue. Modifying the code to: (see line 510) +506 try: +507 lock_func(f, fcntl.LOCK_EX | fcntl.LOCK_NB) +508 lock_func(f, fcntl.LOCK_UN) +509 time.sleep(0.01) +510 except (BlockingIOError, PermissionError): +511 break +512 # the child locked the file just a moment ago for 'sleep_time' seconds +513 # that means that the lock below will block for 'sleep_time' minus some +514 # potential context switch delay +515 lock_func(f, fcntl.LOCK_EX) +516 dt = time.monotonic() - start_time +517 self.assertGreaterEqual(dt, self.sleep_time) +518 self.stop_alarm() fixes this. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35633> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
