As of November 1st, when you push a change to mozilla-central, the following builds and tests get triggered:
That's 111 distinct build and test jobs that get spread out across our build and tests pools. A total of 40 machine hours per checkin in our main build, test and talos pools is used, plus an additional 25 machine hours on the mobile devices!!!
In addition, we also do certain types of jobs on a periodic basis:
- Nightly builds
- XULRunner builds
- Shark builds
- Code coverage runs
- L10n repacks for 72 locales and 7 platforms (Windows, Mac OSX, Linux, Windows Fennec, Mac OSX Fennec, Linux Fennec, Maemo); that's 504 individual repacks!
In the course of collecting the data for this post, I've been constantly amazed at the amount of stuff that we're doing, and the scale of the infrastructure! The list above is just for our mozilla-central branch, and I've most likely missed something. We do similar amounts of work for our other branches as well: Try, mozilla-1.9.2, mozilla-1.9.1, TraceMonkey, Electrolysis, and Places. Things have certainly changed a lot in the past year.
