The Next Mesa Version Is Turning Into A Monstrous Release
With the main Mesa drivers (Intel, RadeonSI, NVC0) jumping ahead to OpenGL 4.3 and mostly done with OpenGL 4.4/4.5, plus Intel adding their Vulkan driver, and many other improvements over the past three months, the next stable release of Mesa is going to be massive.
This next version of Mesa is still referred to as Mesa 11.3-dev in Git, with no patches yet proposed for bumping it to Mesa 12.0 considering the new OGL milestones. Anyhow, with the crazy amount of new features I was interested in running some statistics on the code-base to see how its size and evolution compares to earlier Mesa releases. This article provides those numbers.
All numbers are with Mesa Git master as of this morning. When looking at the changes from Mesa 11.2 to the current Git, there's been 1725 files changed, 196686 insertions(+), 44708 deletions(-). In other words, more than 150,000 lines of new code in three months! (151,978 new lines of code for Mesa 11.3 as of this morning.)
For reference, going from Mesa 11.1 to 11.2 was 2269 files changed, 215657 insertions(+), 135942 deletions(-). So for that previous three month cycle, just 79,715 lines of new code, or about half of the amount for this current development cycle. In Mesa 11.0 to 11.1 was 1356 files changed, 111405 insertions(+), 47824 deletions(-) or 63,581 lines of new code.
Pretty much whatever way you want to dice it, Mesa 11.3 is going to be a massive release with around twice as many lines of new code as in the previous few releases. Here's the CLOC output of the current Mesa Git tree, for those curious.
