Hello release team,

blazar-nova is a package including a nova scheduler filter, which must be installed together with nova to be used.

The blazar-nova deliverable for Yoga was tagged with 2.4.0 at the time of the final release for non-client libraries. A few days ago, stable/yoga patches were automatically proposed. This is when I discovered that the lower-constraints job was broken because nova bumped some requirements / lower-constraints after we released [1] [2]. Because blazar-nova and nova are installed together, we keep our requirements in sync for testing purposes.

Now, I believe it is just the lower-constraints testing that is broken, since nova requirements are still compatible with what blazar-nova requires: nova just requires more recent versions of some packages. I can run "pip install blazar-nova git+https://opendev.org/openstack/nova.git@master#egg=nova" fine.

I fixed the issue on the blazar-nova master branch [3] and proposed a backport to stable/yoga [4], but realised this was probably breaking release policy.
Should we leave stable/yoga as released and just drop the lower-constraints job?

As an aside, would it be possible to requalify blazar-nova as a cycle-with-rc deliverable for the next release? It is typed as a library but nothing depends on it: if anything, it depends on nova itself.

Thanks,
Pierre Riteau (priteau)
