761780 - Please remove older heads on Try repo

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[John O'Duinn [:joduinn] (please use "needinfo?" flag)]

...as its getting slow again. :bz reports 3m52s to push.

(bug#734225 has details of work to do this merging automatically, but kicking this off manually today, just to make TryServer life better today)

ftr - a clone not updated since 2012-06-04 15:00 PT had 22 heads. current try clone has 2727 heads. That's a lot for 24 hours

IGNORE comment #2 - because of where I got my first clone (a try builder) the first value (22 heads) may be seriously under counted.

Update: this process is taking longer than first estimated. Started with 2727 heads at 1500PT (approx), now at 1950 heads at 2130PT. Script prunes to 200 heads, so still a ways to go.

Hmm.  So I just tried timing a try push today (for the first time since this bug was fixed), and it took 4m45s wall-clock...  :(  Not sure whether we have lots of heads again or whether something else is up.

Thanks for the update - I cited it in bug 734225 comment 17. Since bug 734225 is the long term solution, please add further updates there.
