[Bug 2081871] [NEW] Fullstack neutron.tests.fullstack.test_l3_agent.TestHAL3Agent.test_ha_router failed with "eventlet.timeout.Timeout: 90 seconds" while waiting on self._is_ha_router_active_on_one_agent

 

Public bug reported:

This failed here:
https://zuul.opendev.org/t/openstack/build/1a8c094b185d40a4b0df78f4afe25d2e

Traceback:

```

      File "/home/zuul/src/opendev.org/openstack/neutron/neutron/common/utils.py", line 740, in wait_until_true
    eventlet.sleep(sleep)

      File "/home/zuul/src/opendev.org/openstack/neutron/.tox/dsvm-fullstack-gate/lib/python3.10/site-packages/eventlet/greenthread.py", line 38, in sleep

    return self.greenlet.switch()

    eventlet.timeout.Timeout: 90 seconds

    
During handling of the above exception, another exception occurred:


    Traceback (most recent call last):

      File "/home/zuul/src/opendev.org/openstack/neutron/neutron/tests/base.py", line 178, in func
    return f(self, *args, **kwargs)

      File "/home/zuul/src/opendev.org/openstack/neutron/neutron/tests/fullstack/test_l3_agent.py", line 420, in test_ha_router
    common_utils.wait_until_true(

      File "/home/zuul/src/opendev.org/openstack/neutron/neutron/common/utils.py", line 745, in wait_until_true
    raise WaitTimeout(_("Timed out after %d seconds") % timeout)

    neutron.common.utils.WaitTimeout: Timed out after 90 seconds
```

The output of the failure is not very helpful. One idea here to improve
the log message could be to make wait_until_true and/or the passed
predicate function to report additional information on timeout. Then the
next time it hits, we may have more information.
