This morning I was using GitStats on Mesa. It's been a few years since looking at the top contributors to Mesa so I found it time to look again to see how the development pace and contributor list has changed. As well, I was looking through the commit list of Mesa and other key projects to find any other active independent contributors that have been off my radar but good possible recruits for working at Valve Software on Linux. We're also now more than half-way through 2012, so it's interesting to look at how Mesa's been developing for the first half of the year.
The reporting period for these results begin on 14 February 1998, spanning 5,242 days with commits happening on 3,803 of those days. As of today there are 4,278 files in the Mesa repository that amount to 474,973 lines of code. There have been a total of 51,158 commits from 471 developers.
One of the somewhat surprising graphs was in terms of Mesa's commits per year.
The raw number of commits though isn't too revealing but still has some weight. 2010 being a high point for Mesa development isn't entirely surprising since that's when the Radeon and Nouveau Gallium3D drivers were really starting to come together, various Gallium3D state trackers emerging, Intel making much progress with their driver, etc.
As another possible sign of development slowing a bit (or at least not drawing in much blood) when it comes to Git statistics is the number of developers contributing. So far this year there's been 103 different people that have committed to the Mesa Git code-base. This is in comparison to 166 different individuals in 2011, 161 different people in 2010, or even 119 in 2009. We'll see if this number of developers changes vastly by year's end.
