My push to branches 9.3 and up seems to have broken the buildfarm

Your configuration specifies to merge with the ref 'master'
from the remote, but no such ref was fetched.

I don't see any problems on my machine

Since I posted the above some animals have built successfully, so
it seems to be only affecting some animals.

I think this isn't anything related to your commit. Both racoon and
macaque have failed for a while. They just happened to run quickly after
your commit, giving the impression that two animals failed
consecutively.

I don't think it has anything to do with your push. A number of members
have built with your latest and look fine at this point, and I'm not
seeing any issues here either.

I do see that macque is having issues, but it's been busted for the past
3 days it looks like.

We have backups from prior to your commit, just in case, but I don't
think there's anything wrong.

Thanks!

Yeah. Several of the critters have been having git issues for weeks
to months. I wonder whether we couldn't teach the buildfarm script
to recover from this automatically ...

Could get very messy, especially when the error is in the mirror, as is
apparently the case here. As I mentioned the other day on the buildfarm
list, I'm playing with a mode that would largely obviate the need for a
mirror. Failure cases are what's worrying me, though.

In this particular case, the owner should probably remove the mirror and
each of the branch pgsql directories.

cheers
