Hi everyone,
As you probably know we are now in a mode in which we develop our next zstream version on the master branch as opposed to how we worked before where the master version was dedicated for the next major version. This makes the rapid changes in master to be delivered to customers in a much higher cadence thus affecting stability.
Due to that we think it's best that from now on merges in the master branch will be done only by stable branch maintainers after inspecting those closely.

What you need to do in order to get your patch merged:
- Have it pass Jenkins
- Have it get code review +2
- Have it mark verified +1
- It's always encourage to have it tested by OST, for bigger changes it's a must

Once you have all those covered, please add me as a reviewer and I'll examine it and merge if everything seems right, if I haven't done it in a timely manner feel free to ping me.

Is the above still the current policy?

Hi Didi,
well, yes it is. what’s the concern?

No "concern", other than I noticed a few times that people other than
Tal merged patches, and yesterday I did the same [1] after getting +1

that’s master branch, not stable branch. 

from Sandro and consulting him, seeing that I have permissions. IIRC I
didn't have permissions until recently, so I wondered if anything

If the re-granting of permissions was a mistake, let's revert. If it's
on purpose, perhaps clarify the situation.

we did a major cleanup of stale people and the convoluted system of groups that accumulated in the past
we now just use a simple “regular” and stable maintainers list. +2 are for respective areas, we do not have a per-area granularity in ovirt-engine project, it’s really just an agreement that you shouldn’t merge patches in areas that are not yours.

oh, no w I get it, you really talk about submitting, not +2:) ok, yes, so that has changed. we’ve concluded that we can go back to previous mode of not distinguishing between +2 and merge rights.
everything else above applies about the patch quality criteria, it’s just that indeed anyone in this list[1] can click the submit button.

I’d love to get to a point when we can automatically gate patches based on OST, but it’s going slow…so for now it’s still manual.

Not sure that's enough, but it would be a step in the right direction.
Sometimes patches won't break OST but are still harmful.

sure, it’s never 100%, still better than today, especially since we started to pay more attention to OST results it’s not only that it brings in a regression, it’s also all that wasted time by people trying to fix OST after such patch.

Did we ever consider going fully to Test-Driven-Development? Not
certain if there are studies/methods to calculate/approximate the
expected extra work this will require. Assuming you want eventually
all developers to also know well-enough OST (in addition to their
specific expertise) and be comfortable patching it, it might make

I think anything more involved would be complicated by the slowness. It’s better than before, but still ~35 minutes at best for basic suite. And it’s fragile so not really that simple to add a test without either breaking it or making it too isolated - too slow for practical use. There are always unit tests of course, that’s a separate matter...
