Hi Sachi and all,
I was recently looking into how stable/liberty branches are set for
neutron
in terms of requirements caps, and I realized that we don’t have neither
version caps nor upper constraints applied to unit test jobs in
stable/liberty gate. We have -constraints targets defined in tox.ini, but
they are not running in gate.
I believe this situation leaves us open to breakages by any random library
releases out there. Am I right? If so, I would like to close the breakage
vector for projects I care (all neutron stadium).
I suggest we do the following:
- unless there is some specific reason for that, stop running
unconstrained
jobs in neutron/master;
Sachi King is working up a bit of data mining to confirm that the
constraints jobs are only failing when unconstrained jobs fail - then
we're going to propose the change to project-config to switch around
which vote.
For what I saw in neutron, it never fails unless there is actual constraint
not bumped.
- enable voting for constraints jobs in neutron/liberty; once proved to
work
fine, stop running unconstrained jobs in neutron/liberty;
I expect the same query can answer this as well.
- for neutron-*aas, introduce constraints targets in tox.ini, enable
jobs in
gate; make them vote there/remove old jobs;
- after that, backport constraints targets to stable/liberty; make them
vote
there/remove old jobs.
We're going to advocate widespread adoption once the neutron master
ones are voting
Does the plan make sense?
Totally :) As non-Neutron-contributors we've just been conservative in
our recommendations; if Neutron wants to move a little faster by
taking on a little risk, thats *totally cool* IMO.
I believe there is general understanding that it’s the way to go, and we
were already happy to be guinea pigs for initial data mining, so I don’t
expect problems getting the core team onboard.
My question was more about what we do with stable/liberty branches. Is it
part of the plan that we backport the constraint jobs there?
