Buildslave gets intermittent errors in the svn step
I'm getting occasional odd errors in the subversion step on my buildslave (http://www.python.org/dev/buildbot/buildslaves/moore-windows): Traceback (most recent call last): File "/data/buildbot/lib/python/buildbot/process/buildstep.py", line 690, in startStep d.addCallback(self._startStep_2) File "/usr/lib/python2.5/site-packages/twisted/internet/defer.py", line 195, in addCallback callbackKeywords=kw) File "/usr/lib/python2.5/site-packages/twisted/internet/defer.py", line 186, in addCallbacks self._runCallbacks() File "/usr/lib/python2.5/site-packages/twisted/internet/defer.py", line 328, in _runCallbacks self.result = callback(self.result, *args, **kw) --- <exception caught here> --- File "/data/buildbot/lib/python/buildbot/process/buildstep.py", line 721, in _startStep_2 skip = self.start() File "/data/buildbot/lib/python/buildbot/steps/source.py", line 184, in start self.startVC(branch, revision, patch) File "/data/buildbot/lib/python/buildbot/steps/source.py", line 445, in startVC raise BuildSlaveTooOldError(m) buildbot.interfaces.BuildSlaveTooOldError: This buildslave (moore-windows) does not know about multiple branches, and using mode=update would probably build the wrong tree. Refusing to build. Please upgrade the buildslave to buildbot-0.7.0 or newer. This is very odd, as (a) a simple rerun fixes the issue, and (b) I'm already on buildbot 0.7.0 or newer (can't recall the exact version). It's a Windows XP system, if that helps. Does anyone have any suggestions? Thanks, Paul.

In my experience this error just means that someone tried to manually trigger a build but put the wrong branch information (or left it blank) on the submission form. -- David

Hmm, wasn't me :-) The reason field on the build is blank, so this looks like it's an automatic build. I'm getting odd failures with some of the tests as well, at the moment - test_smtplib and others failing but when "Re-running failed tests in verbose mode" there were no failures. I wonder if it could be a flaky network connection...? Thanks for the pointer. Paul. PS Is there a better list for this type of question? I'm not sure how interesting it is to general python-dev readers.

test_smtplib is notoriously flaky.

IMHO it's ok for python-dev. It's a pity buildbot issues don't generate more interest though. Regards Antoine.

If it's got an SVN tag indicated, and you can checkout that tag on your slave, then it's probably not the scenario that I was thinking of. In my case, it's almost always me trying to initiate a test build, and forgetting the right branch tag or what its relative to (historically forgetting to put "branches/" in it).

I suppose. Certainly, for this specific error, it's pretty clear that it's not that precise, and various SVN checkout problems can probably be trapped by the error, so it's pretty unlikely it's actually a buildbot version error. What you might try is locating the buildbot log entries (twistd.log) on your slave that correspond to the failed build. It'll show the exact svn command being issued, and you can try it manually in a test tree. If it succeeds then you'll know it was some sort of transient issue - if it fails, it ought to provide useful data as well.

I don't think there's anywhere separate, and generally (recent history being a bit different) buildbot related stuff has been very low volume. So this list is probably appropriate (given what the buildbots are being used for). I expect if it gets too noisy we'll hear about it :-) -- David

I guess that's a buildbot bug. At 2009-11-23 22:14:23, your buildslave disconnected. The master recognized it it as offline. For some reason, it then still decided to start a build, at 22:14:24. With the slave disconnected, all master-side information gets discarded, and it wasn't possible anymore to find out what version of the svn command the slave implements, hence the exception.
