Something prompted me to look at the size of our codebase here in RelEng, and how much it changes over time. This is the code that drives all the build, test and release automation for Firefox, project branches, and Try, as well as configuration management for the various build and test machines that we have.
Here are some simple stats:
2,193 changesets across 5 repositories...that's about 6 changes a day on average.
We grew from 43,294 lines of code last year to 73,549 lines of code as of today. That's 70% more code today than we had last year.
We added 88,154 lines to our code base, and removed 51,957. I'm not sure what this means, but it seems like a pretty high rate of change!
