gerritexec: continuous integration one-liner

gerritexec is a command line tool listening to gerrit on a designated project. On each new patchset, it will:

  • git clone the project
  • git pull the patchset
  • cd in the git tree and run a script
  • positively review the patchset ( +1 ) if the program exit(0)
  • negatively review the patchset ( -1 ) otherwise

For instance It can be used to run the integration tests found in the git tree of the stackforge/puppet-ceph project:

GEM_HOME=~/.gems gerritexec --hostname review.openstack.org \
           --username puppetceph \
           --script ' ( bundle install ; bundle exec rake spec:system ) > /tmp/out 2>&1 ; r=$? ; pastebinit /tmp/out ; exit $r #' \
           --project stackforge/puppet-ceph

Larger projects should consider using zuul or a gerrit jenkins plugin.

gerrit with jenkins : installation and configuration

The review and project management for Git based projects is installed on a virgin Debian GNU/Linux wheezy. Developers of l2mesh must submit patchs to the git repository to gerrit:

$ git review
remote: Resolving deltas: 100% (1/1)
remote: Processing changes: new: 1, done
To ssh://loic@gerrit.the.re:29418/l2mesh
 * [new branch]      HEAD -> refs/publish/master/master

Gerrit is bound to jenkins : it will run tests on the patch to be reviewed and let gerrit know if it succeeds. If a developer reviews the patch positively, it can be merged into the repository.
