Auto-tools/Projects/MozmillBuildbot

This page documents the work from https://bugzilla.mozilla.org/show_bug.cgi?id=516984 : Run Mozmill Tests with buildbot

This is an Auto-tools project and a Q2 goal

Accomplished Work

• reworked patch from bug 516984 so that it would cleanly apply: https://bugzilla.mozilla.org/attachment.cgi?id=434790 (March 24, 2010)

• added patch to disable notification: http://k0s.org/mozilla/hg/buildbotcustom/.hg/patches/rev/8ba008fdce67 ; i'm not sure if this is complete or not, but staging instances of buildbot should not email tinderbox or other live recipients

• added patch to allow copying buildbot configuration: http://k0s.org/mozilla/hg/buildbot-configs/rev/aa3ff093fa4b ; useful for making new buildmasters as it clones versus symlinks to a versioned master

• added patch to raise a more verbose exception to diagnose download error: http://k0s.org/mozilla/hg/buildbotcustom/.hg/patches/rev/71b8c045d03a

Outstanding Issues

• Mozmill build fails on download:

exceptions.IndexError: tuple index out of range

The patch at http://k0s.org/mozilla/hg/buildbotcustom/.hg/patches/rev/71b8c045d03a reveals build.source.changes is in fact an empty tuple. This is from force build

Outstanding Work

• Add corrections to https://wiki.mozilla.org/Buildbot and linked pages

Long-term Recommendations

These recommendations are hereby recorded for future use. Their need should be assessed before filed as bugs and made actionable.

• Use templates for buildbot-configs: the configurations in http://hg.mozilla.org/build/buildbot-configs are hard-coded for the setup for VMs. Instead, they could be made templates for easy deployment. Cleanup should also be done so that the configurations are more universal and adding new configurations is easy.
