560920 - Remove no-multiple-heads hg hook from build/buildbot-configs, build/buildbotcustom

Status: RESOLVED FIXED

(mozilla.org Graveyard :: Server Operations, task)

Description

[Chris AtLee [:catlee]]

Please remove the hg hook that prevents multiple heads from landing on our build/buildbot-configs and build/buildbotcustom repositories.

Is there a hook that enforces a single head per named branch?  If so, we'd like that!

We can't land anything on default currently because of this.
If this is blocked on something, I can back out catlee's branch, but I'm hoping this is quick?

You currently have this hook for that repo.

[hooks]
pretxnchangegroup.a_singlehead = /repo/hg/scripts/hg_require_single_head

I changed it to this.
[hooks]
pretxnchangegroup.a_singlehead = python:mozhghooks.single_head_per_branch.hook

Oh sorry, I had only enabled it for buildbotcustom, I have now enabled it for buildbot-configs as well.

Yay!
Was able to push to buildbot-configs with push -f.
Thanks Aravind!
