[openstack-dev] Further closing the holes that let gate breakage happen

I was looking at the most recent gate breakage in Neutron , fixed
by . This gate breakage was held off for some time by the
upper-constraints.txt file. This is great progress and I applaud it.
I'll continue to cheer on this effort.
Now to the next problem. If my assessment of this gate failure is
correct, the update to the upper-constraints file  was merged
without running all of the tests across all of the projects that would
be broken by bringing in this new constraint. So, we still get
breakage and it is still (IMO) too often.
As I see it, there are a couple of options.
1) We run all tests under the upper-constraints control on all updates
to the upper constraints file like . This would probably mean each
update has a very long list of tests and we would require that they
all be fixed before the upper constraint update can be merged. This
seems like a difficult thing to coordinate all at once.
2) We handle upper-constraints much like we do the global requirements
updates. We have the master and a bot that proposes updates to it out
to the individual projects. This would create a situation where
projects are out of sync with the master but I think if we froze the
master early enough, we could have time to reconcile before release.
3) We continue to allow changes in the upper constraints to break
Are there options that I missed? What is your opinion? In my
opinion, gate breakage happens a bit too often and the effect on the
community is widespread. I'd like to contain it even a little bit
