Just FYI,
Our experience with git on the NAMD side has not been without issues.
In fact, we have had as much or more difficulity training people to use
Gerrit than we ever had with having people send us diffs via email.
The fact is that working on large scientific software is hard work,
and one is either prepared to do that work, or not. Whether the code
is in git, mercurial, svn, cvs, or whatever, hardly makes any practical
difference. I've used them all and most of the issues come down to the
quality of the code contributions if/when they occur, and the diligence
of the contributor in testing their code. I would say that something like
99% of my time is spent on the latter issue. If someone can't deal with
diffs, then they may not be willing to properly test their code either.
The revision control system in use is probably the least important aspect
of software development at this level. Our experience with NAMD and Gerritt
is causing things to move in a new direction there, and when we have
come to what we think is a better solution on the NAMD side, we'll see about
moving VMD to match. So far the git/Gerrit attempt over the past year+
has not been a panacea. Several of the key NAMD contributors were completely
blown away by the complexity of working with the code review system, and this
ended up creating more problems for us than it has solved thus far. Until
things are working well with git on the NAMD side, I don't expect to change
anything on the VMD side, it would be wasted effort until we feel that
there's a net positive outcome.
Best,
John
