Hi

I use git since a while for my own projects (how surprise).

The company I work for still uses a CVS(nt), and this sucks, time to
changed that. We have a use case we often have problems with. If git would
solve this problem, I would really have a good arg for the managers.

The codebase managed by CVS is quite huge and therefore we have daily and
nightly builds.

So do we, where I work.

One problem we have is, that if there is a commit to cvs while the cvs
update of the build job is running (and this takes 20 minutes), then we
get some inconsistence, the build will fail.

Yes. That's how it works with CVS. We try to work around that problem
by using automatic tags ('nightly'-something) set individually on each
module, common for the whole repo, and then we 'cvs export' by tag
instead of cvs update. This works reasonably well (and is reproducible
due to the tag), but is not anywhere as fast as git would be.

So the question is, if we would use git, this inconsistence would not be
possible because the git pull will get the state of the sha1. Right?

Git commits are atomic, so you won't see that inconsistency problem
with git. So, Right.
