Continuous Integration System for a Python Codebase

We run Buildbot - Trac at work. I haven't used it too much since my codebase isn't part of the release cycle yet. But we run the tests on different environments (OSX/Linux/Win) and it sends emails — and it's written in Python.

One possibility is Hudson. It's written in Java, but there's integration with Python projects:

Hudson embraces Python

I've never tried it myself, however.

(Update, Sept. 2011: After a trademark dispute Hudson has been renamed to Jenkins.)

Second the Buildbot - Trac integration. You can find more information about the integration on the Buildbot website. At my previous job, we wrote and used the plugin they mention (tracbb).What the plugin does is rewriting all of the Buildbot urls so you can use Buildbot from within Trac. (http://example.com/tracbb).

The really nice thing about Buildbot is that the configuration is written in Python. You can integrate your own Python code directly to the configuration. It's also very easy to write your own BuildSteps to execute specific tasks.

We used BuildSteps to get the source from SVN, pull the dependencies, publish test results to WebDAV, etcetera.

I wrote an X10 interface so we could send signals with build results. When the build failed, we switched on a red lava lamp. When the build succeeded, a green lava lamp switched on. Good times :-)
