[LLVMdev] "surprising" empirical numbers about git vs. svn
I just ran some real, hard numbers about git and svn usage. These are just numbers, I don't want people to jump to conclusions. I basically just wrote a little script that iterates over every message in llvm-commits (for as long as I have been subscribed, which is about since Feb 2012) and if there are patches attached it tallies up the counts of what kind of patch it looks like. It uses extremely simple (but apparently effective) heuristics to determine whether a patch is from svn or git. The script is attached if you want to take a peek. The results are as follows: sean:~/pg/llvm/patchcount % ./patchcount.py error 2 git 1082 svn 1057 unknown 23 vanilla 28 So basically, git and svn are roughly the same for patches that are received on llvm-commits. Obviously, this ignores a number of things that are relevant to determining the prevalence of svn vs git for *general development*. These numbers indicate exactly what it says on the wrapper: number of patches sent to llvm-commits that are generated by each program. -- Sean Silva -------------- next part -------------- A non-text attachment was scrubbed...
