[ovirt-devel] [VDSM] VdsmClientTests.test_event_handler - flaky test?

Seen this unrelated failure today on: https://gerrit.ovirt.org/#/c/107206/ Build: https://jenkins.ovirt.org/job/vdsm_standard-check-patch/18831//artifact/c... This smells like the known issue with handling connections. I think the test was disabled in the past, and it started to fail since we enabled the stomp tests recently. If you see the same failures, lets mark this test as xfail until we have time to debug this. See failure bellow. =================================== FAILURES =================================== ______________________ VdsmClientTests.test_event_handler ______________________ self = <stomprpcclient_test.VdsmClientTests testMethod=test_event_handler> def test_event_handler(self): with self._create_client() as client: event_queue = queue.Queue() sub_id = client.subscribe(EVENT_TOPIC, event_queue) lib/yajsonrpc/stomprpcclient_test.py:215: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ self = <stomprpcclient_test._MockedClient object at 0x7f87ab72d160> namespace = 'Test', method_name = 'sendEvent', kwargs = {} method = 'Test.sendEvent', timeout = 3 req = {'jsonrpc': '2.0', 'method': 'Test.sendEvent', 'params': {}, 'id': 'aa4919ae-558f-4403-aab8-f64f0d7cd2ff'} responses = None def _call(self, namespace, method_name, **kwargs): """ Client call method, executes a given command Args: namespace (string): namespace name method_name (string): method name **kwargs: Arbitrary keyword arguments Returns: method result Raises: ClientError: in case of an error in the protocol.
