[Bug 2034700] Re: Add and delete port test fails in the Debian package due to error logged from vif-plug-representor

[Steve Langasek]

Hello Frode, or anyone else affected,

Accepted ovn into lunar-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/ovn/23.03.1-1ubuntu0.23.04.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
lunar to verification-done-lunar. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-lunar. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: ovn (Ubuntu Lunar)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-lunar

Title:
  Add and delete port test fails in the Debian package due to error
  logged from vif-plug-representor

Status in ovn package in Ubuntu:
  New
Status in ovn source package in Lunar:
  Fix Committed

Bug description:
  OVN commit 264c825f0a0e ("ovn-controller: remove un-necessary "trying
  to release" warnings") added a test that fails if any warning or error
  is logged from the ovn-controller.

  This revealed the fact that the OVN-VIF representor plugin logs an error while running the test:
  ./ovn.at:35873: check_logs "" hv1

  942. ovn.at:35873: 942. Add and delete port -- ovn-northd -- parallelization=yes -- ovn_monitor_all=no (ovn.at:35873): FAILED (ovn.at:35873)

  From cursory view, I do not see this logged on an actual production
  setup with ovn-controller running directly on a host. I do see it when
  running this test in a container though.

  We should probably make the failure graceful at the initialization
  stage, and rather log warnings if this state is found while doing a
  lookup, or just lower the severity to INFO/DBG.
