ie. if the new policy was introduced at the start
of the year, it would
have caused at least a two-week delay in all three SWAT windows at one
point at least, and it would have caused an ever-growing backlog of
patches
for EU mid-day.
2 week delays aren't possible as all SWATs are backports of master, so
if waiting a week it'd go out with the normal train ;)
No, majority of patches deployed in a SWAT window is in
operations/mediawiki-config and this repository do not have release
branches and/or train deploys. If I'd be the only one using certain SWAT
window and I'd need to deploy 5 patches per window, the first window I'll
deploy 4 patches and the remaining would be rescheduled, the second window
I'll have 1 patch rescheduled and 5 new patches (6 in total), 4 will be
deployed, 2 will be rescheduled, the third window I'll have 2 patches
rescheduled and 5 new patches (7 in total), 4 will be deployed, 3 will be
rescheduled, etc. etc. etc.
I'd have a constantly raising backlog of patches and will be enforced to a)
reserve a window to deploy all waiting patches b) use another SWAT.
This will cause even bigger pain after US holidays because then bigger SWAT
windows are expected.
I know that deploying 8 patches in a window is a problem (at least in EU
SWAT window, don't use the other windows that much), but 4 is the other
extreme.
But point taken and thanks for the data.
I'm comfortable with a 6 patch "limit". I put limit in scare quotes
because I assume you all know that high priority changes can go out when
they need to go out. The limit is to reduce SWAT deploy stress for what
is possible in a 1 hour window and not try to squeeze things in and
reduce the clarity when watching logs.
