We seem to have an issue in the CI, starting this week.
All tests pass, but creating coverage report fail:
+ generate_combined_coverage_report
+ pushd tests
~/tests ~
+ pwd
/home/jenkins/workspace/vdsm_standard-check-patch/vdsm/tests
+ ls .coverage-gluster .coverage-lib .coverage-network .coverage-nose
.coverage-storage .coverage-virt
.coverage-gluster
.coverage-lib
.coverage-network
.coverage-nose
.coverage-storage
.coverage-virt
+ python3 -m coverage combine .coverage-gluster .coverage-lib
.coverage-network .coverage-nose .coverage-storage .coverage-virt
No usable data files

This looks like a bug in coverage, or maybe we use the wrong version
of this tool?
+ teardown
+ res=1
+ '[' 1 -ne 0 ']'
+ echo '*** err: 1'
*** err: 1
Additionally, we have this very strange error:
+ teardown_storage
+ python3 tests/storage/userstorage.py teardown
python3: can't open file 'tests/storage/userstorage.py': [Errno 2] No
such file or directory
This error is impossible, since tests/storage/userstorage.py is part
of the source.
Is it possible that some other code has deleted the source while a
build was running?
+ echo 'WARNING: Ingoring error while tearing down user storage'
WARNING: Ingoring error while tearing down user storage
We were careful not to fail the build because this issue, but it failed because
coverage report could not be created.
There are multiple instance of this issue:
-
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/26107//artifact/c...
-
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/26103//artifact/c...
-
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/26102//artifact/c...
I think Eyal reported another instance, but I cannot find it now.
2 weeks ago we updated pytest and pytest-cov to latest version, but we did
not see this issue in the CI when we tested the change:
https://gerrit.ovirt.org/c/vdsm/+/112604
And CI was fine since then, so this may not be related, unless this is
a regression
in latest coverage or pytest-cov.
