Hello Everyone, With the recent update in 'coverage' constraints to 6.4[1], openstacksdk-functional-devstack is broken in stable/ussuri branch. openstacksdk-functional-devstack running on stable branches use the master SDK and master constraints and in stable/ussuri this job runs on bionic/py3.6 and now fail for 'coverage' 6.4 version conflict. - https://zuul.opendev.org/t/openstack/build/3d3c21d804ec498e957c1c64470c991b/log/job-output.txt#43332 - https://storyboard.openstack.org/#!/story/2010057 As we know requirements generate constraints for py3.8|9 so if we want this job to run with master constraints then it needs to run on compatible python and distro. This is why I am proposing to run this job on focal - https://review.opendev.org/c/openstack/openstacksdk/+/843968 But clark made a good point in IRC that we should test this job with all python versions supported by the stable branch which we can do by testing this job with stable branch constraints and see if still, master SDK runs on those python versions and stable constraints. This is something we can improve if SDK team agrees or have the bandwidth. Anyways please do not recheck on stable/ussuri until this job is fixed (843968 is merged).
