New submission from STINNER Victor <vstin...@python.org>:
x86 Windows7 3.x: https://buildbot.python.org/all/#/builders/58/builds/3015 If I recall correctly, this buildbot is known to be slow. It sounds like a race condition. ERROR: test_queue_feeder_donot_stop_onexc (test.test_multiprocessing_spawn.WithProcessesTestQueue) ---------------------------------------------------------------------- Traceback (most recent call last): File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows7\build\lib\test\_test_multiprocessing.py", line 1132, in test_queue_feeder_donot_stop_onexc self.assertTrue(q.get(timeout=1.0)) File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows7\build\lib\multiprocessing\queues.py", line 108, in get raise Empty _queue.Empty Extract of the test: def test_queue_feeder_donot_stop_onexc(self): # bpo-30414: verify feeder handles exceptions correctly if self.TYPE != 'processes': self.skipTest('test not appropriate for {}'.format(self.TYPE)) class NotSerializable(object): def __reduce__(self): raise AttributeError with test.support.captured_stderr(): q = self.Queue() q.put(NotSerializable()) q.put(True) # bpo-30595: use a timeout of 1 second for slow buildbots self.assertTrue(q.get(timeout=1.0)) # <===== FAIL HERE ===== close_queue(q) ... Hum, "bpo-30595: use a timeout of 1 second for slow buildbots" sounds like this test depends on time which is bad for reliable tests. Would it be possible to use a more reliable synchronization primitive? If no solution is found, the workaround is to use a timeout of 60 seconds instead of just 1 second... ---------- components: Tests messages: 352712 nosy: pablogsal, vstinner priority: normal severity: normal status: open title: test_multiprocessing_spawn: test_queue_feeder_donot_stop_onexc() failed on x86 Windows7 3.x versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38212> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
