Hello. I've noticed once again that job "gate-tempest-dsvm-neutron-src-oslo.concurrency-liberty" is always failing. After looking at the failure I found that the core issue is ContextualVersionConflict [0]. It seems that we have conflicting requirements for oslo.utils here, and we do: in Liberty upper-constraints set oslo.utils to 3.2.0 version [1] while in master oslo.concurrency requires at least 3.4.0 which is stated in global-requirements [2]. Other projects have similar issues too: - oslo.utils fails [3] because of debtcollertor 1.1.0 [4] while it requires at least 1.2.0 in master [5]; - oslo.messaging fails the same way because of debtcollector [6]; - etc. Looks like a lot of wasted cycles to me. It seems we need to either bump stable/liberty upper-constraints to match current requirements of modern oslo libraries or somehow adapt backward compatibility jobs to ignore upper-constraints for these libraries. Of course we could also stop running these jobs altogether for projects that have conflicting dependencies, but I think the reason we have them in the first place is that we want to see that we can use new oslo libraris with older OpenStack releases.
