Bug#1029959: ceilometer: flaky autopkgtest: regularly times out

[Paul Gevers]

Source: ceilometer
Version: 1:19.0.0-1.1
Severity: serious
User: debian...@lists.debian.org
Usertags: flaky

Dear maintainer(s),



Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul

I looked at the results of the autopkgtest of your package. I noticed that it regularly fails. What's worse, particularly on i386 but also on other architectures, it times out regularly. ceilometer.tests.unit.test_novaclient.TestNovaClient.test_with_flavor_and_image_unknown_image_cache ... ok ceilometer.tests.unit.test_novaclient.TestNovaClient.test_with_missing_image_instance ... ok ceilometer.tests.unit.test_polling.PollingTestCase.test_check_meters_include_exclude ... ok File "/usr/lib/python3/dist-packages/eventlet/hubs/hub.py", line 476, in fire_timers File "/usr/lib/python3/dist-packages/eventlet/hubs/timer.py", line 59, in __call__ File "/usr/lib/python3/dist-packages/eventlet/semaphore.py", line 147, in _do_acquire
