Ah, it would be *very* useful to have nightly jobs too, including l10n repacks.

JB b2g builds are also missing, as well as b2g tests.

They are prioritized as the lowest of the low, just like everything else on twigs, though, aren't they? I noticed that the utterly pointless ones on Cedar, which does things like run four nightlies that nobody looks at on a single push, were pending for almost two hours today before they finally ran.

That's true, but they still block jobs that came in after the slave picked up a repack from starting. If we could reduce the # of locales we do it wouldn't be so bad. Might be able to do that by changing the all-locales file (like https://github.com/mozilla/build-buildbot-configs/blob/master/mozilla/l10n/all-locales.mozilla-central) come to think of it. We might have other bumps in doing l10n on twigs - I don't think we've done it before.

I think this addresses every concern in this bug... l10n is nightly-only, which should reduce the load. :glandium, could you trim http://hg.mozilla.org/projects/birch/file/7e40af5a70ee/browser/locales/all-locales and http://hg.mozilla.org/projects/birch/file/7e40af5a70ee/mobile/android/locales/all-locales to a subset you care about, to further reduce load? I think Android chunks into 5 so we may need at least 5 locales, not sure.

Comment on attachment 8333863 [details] [diff] [review] birch.diff Review of attachment 8333863 [details] [diff] [review]: ----------------------------------------------------------------- I really think it's a bad idea to run l10n nightlies on twigs. Not only does it waste a ton of machine time, it can create confusion for localizers. If we must do this can we use a custom all-locales file that only repacks x-testing?

I think it's necessary, especially since :glandium et al are making build system changes that regularly break l10n.

(Ben asked me to change reviewers in IRC.)

How about not running them periodically, but having them triggerable from self-serve?

(In reply to Mike Hommey [:glandium] from comment #11) > How about not running them periodically, but having them triggerable from > self-serve? Possibly? This is the fastest fix though, since the patch is here+reviewed. We can back parts of this patch out when bug 793989 lands. (Are you talking about all nightlies/pgo, or just the l10n with this statement?)

(In reply to Aki Sasaki [:aki] from comment #13) > (In reply to Mike Hommey [:glandium] from comment #11) > (Are you talking about all nightlies/pgo, or just the l10n with this > statement?) All of the above.

Ok. Yeah, bug 793989.

Can we add Nightlies and l10n builds for Android to this list, if it's not already there? This could close Bug 941290.

something[s] here made it to production

I'm going to be optimistic and call this done, but not optimistic enough to resolve the bug til we see it.

I see PGO on birch: https://tbpl.mozilla.org/?tree=Birch&showall=1&jobname=pgo I see nightlies on birch: https://tbpl.mozilla.org/?tree=Birch&showall=1&jobname=nightly
