Hi all,

I’d like to introduce a new initiative around stable branches for neutron 
official projects (neutron, neutron-*aas, python-neutronclient) that is 
intended to straighten our backporting process and make us more proactive in 
fixing bugs in stable branches. ‘Proactive' meaning: don’t wait until a known 
bug hits a user that consumes stable branches, but backport fixes in advance 
quickly after they hit master.

The idea is simple: every Fri I walk thru the new commits merged into master 
since last check; produce lists of bugs that are mentioned in 
Related-Bug/Closes-Bug; paste them into:

https://etherpad.openstack.org/p/stable-bug-candidates-from-master

Then I click thru the bug report links to determine whether it’s worth a 
backport and briefly classify them. If I have cycles, I also request backports 
where it’s easy (== a mere 'Cherry-Pick to' button click).

After that, those interested in maintaining neutron stable branches can take 
those bugs one by one and handle them, which means: checking where it really 
applies for backport; creating backport reviews (solving conflicts, making 
tests pass). After it’s up for review for all branches affected and applicable, 
the bug is removed from the list.

I started on that path two weeks ago, doing initial swipe thru all commits 
starting from stable/liberty spin off. If enough participants join the process, 
we may think of going back into git history to backport interesting fixes from 
stable/liberty into stable/kilo.

Don’t hesitate to ask about details of the process, and happy backporting,

Ihar
