[Buildbot-devel] git 1.7.7 trouble

[Gerd Hoffmann]

  Hi folks,

Looks like a recent git change broke buildbot.  One of my build slaves,
running Fedora 16, stopped working recently.  Also git was updated from
1.7.6 to 1.7.7 on that machine recently, which I think is the root cause
of the failure.  The other build slaves running older git releases are
doing just fine.

Specifically the command '/usr/bin/git branch -M master' used by
buildbot stopped working, I have this error message in the logfile:

  fatal: Cannot force update the current branch.

Updated buildbot on the master to the latest release (0.8.5) today,
didn't help.

Suggestions anyone?

cheers,
  Gerd
