This project aims to rebuild the Wikimedia continuous integration legacy server (currently hosted on a virtual machine) on a dedicated server in eqiad, our new data center. Chad Horohoe started to consolidate the platform to run automated tests systematically at post-commit time, to check that the SVN trunk is in an (almost) constantly deployable state. This project also relates to the will to have more frequent code deployments, as continuous integration will give us more confidence in new code if it already passed the automated tests. The new server will be combined with TestSwarm, a distributed continuous integration tool for JavaScript, currently hosted on the Toolserver. Timo Tijhof reached out to the TestSwarm team, who were enthusiastic about incorporating our improvements, notably on performance.

Chad Horohoe continued to set up the virtual machine environment, while the Operations team set up the physical hardware in the Virginia data center. The final server will use Jenkins instead of CruiseControl.

Chad Horohoe worked with Daniel Zahn to set up the dedicated server in our Virginia data center. Its configuration was automated with Puppet. TestSwarm remains to be pupettized. The server is expected to be put in production in early October.

Chad Horohoe worked with the operations team to finalize the setup of the testing server, now online at http://integration.mediawiki.org. It is currently running Jenkins (PHPUnit), and TestSwarm should be added soon. Antoine Musso will be leading this project going forward.

Antoine Musso has been making many improvements and additions to the system. Chad Horohoe has the beginnings of a TestSwarm .deb package, which he will soon check in and hand off to Antoine (see bug 32433).

Chad Horohoe and Antoine Musso created a Debian package for TestSwarm, so it can be installed in our common infrastructure with Jenkins. Antoine and Timo Tijhof wrote a script to fetch individual revisions of MediaWiki's code, in order to run tests against each one of them. PostgreSQL testing in Jenkins is planned for implementation in the coming weeks.

Testswarm (used to test our javascripts) was packaged and now runs from Labs. A first step toward production deployment;
