As a CM (Configuration Management) weenie, I loathe CVS because of how
slow the branching and labeling is. At my last company, it took close
to an hour to branch/label the code, which made effective CM
impractical. With subversion I can branch and label in under a second
for a tree containing thousands of files.
Subversion also has directory versioning, which means you can now record
and *undo* file renames or moves. Atomic commits are very nice. It can
also handle empty directories. Subversion treats every file as binary,
so none of that -kb nonsense. There are no standard procedures that
involve hacking the back end repository. CVS is becoming more and more
out-dated and needs to go away.
The biggest difficulty with Subversion is the paradigm shift. Coming
from 7 years of ClearCase, the One Revision Number thing took a lot of
getting used to. That and the lack of a "proper" version tree.
Generally speaking, as a CM weenie, and after a bit of time, I find
Subversion's tree based paradigm to be a great improvement over the
file-centric paradigm started with RCS. It just takes a bit of getting
The biggest flaw with Subversion right now is the lack of proper merge
