Currently, to make 24-hour backouts a reality, we need to automate the comparing of a regression in a revision against a base (previous?) revision. This should be in perfherder itself, here is a rough method signature: > perfherder.compare(base, new, branch, platform, test) ... (possibly thclient.ph.compare(...) ? > * base: revision of the old point to compare against > * new: revision of the new point with regression/fix > * branch: needed to get signature > * platform: needed to get signature > * test: needed to get signature I am not very acquainted with perfherder, so it may be that we already have this feature (tell me if so!).

we have all alert generation and management inside of perfherder as well as simple methods for finding the base revision in a compare view. While this doesn't meet the full requirements of the bug, I would say our use case is resolved.
