[ros-dev] Microsoft switched to Git

[Zachary Gorden]

I've used both git and svn in work environments. If all you do is git pull
and git push, you end up with lots of noise in the commit log with git
tracking every single merge because you don't rebase. Combined with the
fact that git has an upper limit on how much history it can track and the
solution literally being to purge history, I'm not exactly sure why all of
you are so enthused about it. Unless the team wants to adopt having a
single person being responsible for all commits going into the canonical
master repo to avoid all of the problems with how git tracks history, the
commit log is going to be next to useless for actual tracking of history.
If you don't care about the commit history, then sure, go ahead, but I
personally would like to be able to easily track changes back cleanly. We
get that basically for free with svn right now. With git, the usage
patterns that those of you pushing for git are promoting actively works
against keeping a clean history.
