The MockRebuild step rebuilds a SourceRPM package:

Mock (http://fedoraproject.org/wiki/Projects/Mock) creates chroots and builds packages in them. It populates the changeroot with a basic system and the packages listed as build requirement. The type of chroot to build is specified with the root parameter. To use mock your Buildbot user must be added to the mock group.

from buildbot.plugins import steps

f.addStep(steps.MockRebuild(root='default', srpm='mypkg-1.0-1.src.rpm'))

The step takes the following parameters


Uses chroot configuration defined in /etc/mock/<root>.cfg.


The directory where the logfiles and the SourceRPM are written to.


The path to the SourceRPM to rebuild.


It is necessary to pass the resultdir parameter to let the master watch for (and display) changes to build.log, root.log, and state.log.
