1167004 - gecko: Per branch cache folders for builders (discussion)

Status: RESOLVED FIXED

(Taskcluster :: General, defect)

Description

[Jonas Finnemann Jensen (:jonasfj)]

Today we had issue where bugs in one branch affected another branch,
because we shared cache folders for object-dir between branches.
(This probably only relevant for object-dir caches, not source clones)

I'm not sure that is wise, or even efficient. Sure we save space, but we also
get a cache that is less likely to be hot. Assuming we don't constantly sync
branches (which we do for some).

anyways, I suggest that we do per-branch cache folders, so someone forgetting to
touch clobber doesn't poison cache folders that other branches use.

@mshal,
I might be wrong I suspect you know the build system a bit, hence, I cc'ed to
to hear if sharing object-dirs between branches is crazy, sane or somewhere
in between :)
