As far as I know from previous mails, the buildbots already do a retry
when git fails. The retry period used today is obviously too short.

We know that git fails rather often and that those failures take some
time. Is there any reason why a buildbot cannot retry until it
succeeds with a much larger time limit than today?

A git retry limit of several hours or even a day would not harm.
Mails from the buildbot are only useful if some user action is
required - when git fails, you can only wait.

Developers who want a fast feedback for their latest commits
can either poll the buildbot, or the buildbot must be configured
to send individual mails with more information.

i finally took a closer look on this failed git reports. It seems like all the 
"git failed" mails are not due to a too short reply period. It is due to the 
buildslave version used on "yuzuki" is not recent enough to perform retries at 
all.

Other buildslaves which have buildbot version 0.8.2 and greater perform 
retries correctly and seem to require only one retry to finally succeed. 
"yuzuki" is running buildbot version 0.7.12 and doesn't perform any retry and 
cause nearly all "git failed" mails since we introduced git-fetch retries.

Stefan, could you update your buildslave "yuzuki"? In meanwhile I try to setup 
mine buildslave also with a new version of buildbot.


Best Regards,
Daniel

Thanks for the pointer.  I have upgraded yuzuki to buildbot 0.8.5.

Another git issue:  Fedora 16 fails because git 1.7.7 errors out on 'git
branch -M master'.  Guess that needs to be fixed in the GitPoller @
buildmaster?

I've also some python bits to send out the log tail with the mails, see
below.

cheers,
  Gerd
