Hey all, Sending this to the ML to try to help others who may not have heard about it yet. I didn't know about myself until I saw the job fail on a random nova patch and I looked around to figure out why. It looks like openstack-tox-pep8 is failing 100% in nova due to a newer version of the mypy library being pulled in since a recent upper-constraints bump: https://review.opendev.org/c/openstack/requirements/+/872065 And the job isn't going to pass until the following fix merges: https://review.opendev.org/c/openstack/nova/+/878693 Finally, to help prevent a breakage for this in the future, a cross-nova-pep8 job has been approved: https://review.opendev.org/c/openstack/requirements/+/878748 and will be on its way to the gate once the aforementioned fix merges. I'll post a reply to this email when it's OK to do rechecks again. Cheers, -melwitt
