The try repository ends up with a ton of extra heads after awhile, which slows down the pushlog and possibly other parts of the repository. We need to deal with this in some automated way, be it stripping heads periodically or automatically recloning on a regular basis - something that doesn't require intervention.

Mass move of bugs from Release Engineering:Future -> Release Engineering. See http://coop.deadsquid.com/2010/02/kiss-the-future-goodbye/ for more details.

Ok so back to dealing with this, there is now a script that IT can run either by a bug request or with a cron job, which they say they prefer not to do it that way, however by looking at the past couple of months of try usage here: https://build.mozilla.org/buildapi/reports/pushes?starttime=1283324400&endtime=1287730800 It looks like midnight on Sunday is a good time, pushes are often 0 and if we were to make it automatically close the try tinderbox page so that pushes to try were stopped with a hook while the cleanup happened then we could feasibly make this entirely automated.

Trying to consolidate this discussion into one place, there is more relevant conversation in bug 554656.
