What are your plans for when you'll deploy wmf.19, branch wmf.20 and deploy
I ask because I have a patch lined up that I wanted to merge today right
after the wmf.20 branch cut, because I want it to spend the full week on
beta labs before it goes to production. I can merge that patch today and
have it go to beta, and have it go into wmf.20 once it gets cut, but I'd
only be willing to do that if I had a guarantee that wmf.20 would not be
cut before early next week. Because it's currently unknown when wmf.20 will
be cut, I don't know what's safe to do.
Unrelatedly, I also have a patch merged in master that fixes a regression
in wmf.19. Since wmf.19 is not deployed right now, the regression doesn't
affect production, but if wmf.19 is ever going to be deployed, then the fix
needs to be cherry-picked into it. Do you know if wmf.19 is going to be
deployed, or is it going to be skipped? Since wmf.19 is not deployed right
now, should I submit a cherry-pick to it for SWAT today so that it gets
unbroken in the event it ever gets deployed?
I understand that you are investigating and will reevaluate after, but it
would be nice to have these questions answered quickly so we have some
sense of what is and isn't going to happen, and aren't blocked by this
uncertainty for much longer,
