Hi there, i run a buildbot for the [http://linuxcnc.org LinuxCNC] project.
Buildbot has been great for us, so first of all thanks!
I recently upgraded my buildmaster from Buildbot 0.7.12 running on Ubuntu
Lucid to Buildbot 0.8.5 running on Ubuntu Precise, and now i have a
strange new problem.
First of all, my buildmaster config and a couple of relevant logs are
here: http://highlab.com/~seb/buildbot-2122/
As you can see, my master config has a scheduler watching our git repo,
and a post-update hook in our repo kicks off the 'checkin' builder.
'checkin' triggers a build-and-test scheduler, and if that passes it next
triggers a couple of packaging and docs-building schedulers. This setup
used to work great with 0.7.12, but since the upgrade to 0.8.5 i get
occasional hangs. The first Trigger does its thing and returns to the
checkin builder, which then runs the second Triggers (which triggers
several schedulers). The second round of schedulers all run and do their
thing, but the 'checkin' builds' second Trigger buildstep never returns!
The waterfall shows all triggered builds completed, but the triggering
build is still yellow and waiting for something. If i stop and restart
the buildbot, it picks right up and begins the next pending build.
Here's a recent run where this happened:
http://buildbot.linuxcnc.org/buildbot/builders/checkin/builds/88
I spoke with tomprince on #buildbot about this issue (and about issue
#2122) recently, and he was able to reproduce the hang:
{{{
<tomprince> seb_kuzminsky: I can reproduce it locally:
https://github.com/tomprince/buildbot-configs/tree/test
<tomprince> It took about 292 builds, while refreshing the webstatus page.
:)
}}}
I'll be happy to do whatever debugging or testing i can to help resolve
this issue.
