Public bug reported: oslo.service fails with python3.9 due to Semaphore() not implementing _at_fork_reinit
when testing oslo.service, it fails with AttributeErrors in python3.9, leading me to believe that oslo.concurrency is not compatible with python3.9 and i'm not sure how to fix it. https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-hirsute/hirsute/amd64/p/python- oslo.service/20201116_120433_0b2e5@/log.gz {0} oslo_service.tests.test_periodic.PeriodicTasksTestCase.test_called_correct [0.008885s] ... ok ERROR [oslo_service.periodic_task] Error during AService.crashit Traceback (most recent call last): File "/tmp/autopkgtest.yxXbpd/build.9dR/src/oslo_service/periodic_task.py", line 216, in run_periodic_tasks task(self, context) File "/tmp/autopkgtest.yxXbpd/build.9dR/src/oslo_service/tests/test_periodic.py", line 54, in crashit raise AnException('urg') oslo_service.tests.test_periodic.AnException: urg ERROR [oslo_service.periodic_task] Error during AService.crashit Traceback (most recent call last): File "/tmp/autopkgtest.yxXbpd/build.9dR/src/oslo_service/periodic_task.py", line 216, in run_periodic_tasks task(self, context) File "/tmp/autopkgtest.yxXbpd/build.9dR/src/oslo_service/tests/test_periodic.py", line 54, in crashit raise AnException('urg') oslo_service.tests.test_periodic.AnException: urg {0} oslo_service.tests.test_periodic.PeriodicTasksTestCase.test_called_thrice [0.005251s] ... ok {0} oslo_service.tests.test_periodic.PeriodicTasksTestCase.test_name [0.002083s] ... ok {0} oslo_service.tests.test_periodic.PeriodicTasksTestCase.test_raises [0.002519s] ... ok Exception ignored in: <function _after_fork at 0x7f4da9878790> Traceback (most recent call last): File "/usr/lib/python3.9/threading.py", line 1486, in _after_fork thread._reset_internal_locks(True) File "/usr/lib/python3.9/threading.py", line 827, in _reset_internal_locks self._started._at_fork_reinit() File "/usr/lib/python3.9/threading.py", line 527, in _at_fork_reinit self._cond._at_fork_reinit() File "/usr/lib/python3.9/threading.py", line 253, in _at_fork_reinit self._lock._at_fork_reinit() AttributeError: 'Semaphore' object has no attribute '_at_fork_reinit' Exception ignored in: <function _after_at_fork_child_reinit_locks at 0x7f4da93150d0> Traceback (most recent call last): File "/usr/lib/python3.9/logging/__init__.py", line 251, in _after_at_fork_child_reinit_locks handler._at_fork_reinit() File "/usr/lib/python3.9/logging/__init__.py", line 890, in _at_fork_reinit self.lock._at_fork_reinit() File "/usr/lib/python3.9/threading.py", line 126, in _at_fork_reinit self._block._at_fork_reinit() AttributeError: 'Semaphore' object has no attribute '_at_fork_reinit' Exception ignored in: <function _after_fork at 0x7f4da8a203a0> Traceback (most recent call last): File "/usr/lib/python3.9/threading.py", line 1492, in _after_fork thread._reset_internal_locks(False) File "/usr/lib/python3.9/threading.py", line 827, in _reset_internal_locks self._started._at_fork_reinit() File "/usr/lib/python3.9/threading.py", line 527, in _at_fork_reinit self._cond._at_fork_reinit() File "/usr/lib/python3.9/threading.py", line 253, in _at_fork_reinit self._lock._at_fork_reinit() ** Affects: oslo.concurrency Importance: Undecided Status: New ** Affects: python-oslo.concurrency (Ubuntu) Importance: Undecided Status: New ** Affects: python-oslo.service (Ubuntu) Importance: Undecided Status: New ** Tags: hirsute python3.9 update-excuse update-excuses ** Also affects: python-oslo.concurrency (Ubuntu) Importance: Undecided Status: New ** Also affects: python-oslo.service (Ubuntu) Importance: Undecided Status: New ** Tags added: python3.9 update-excuse update-excuses ** Tags added: hirsute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904424 Title: oslo.service fails with python3.9 due to Semaphore() not implementing _at_fork_reinit To manage notifications about this bug go to: https://bugs.launchpad.net/oslo.concurrency/+bug/1904424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
