Re: Move from CVSNT to SVN?

Sorry I'm late to the conversation, but here's my take:

We moved from CVS to Subversion, and we did it because I liked the features
in Subversion that were completely missing in CVS. Subversion can use Apache
as a protocol which means I can use LDAP that connects to my Windows server.
Before, we were using pserver and I had to manually give everyone an
account. Now, when a developer gets their Windows account, they have
Subversion access.

Subversion handles our end-of-line issues. In CVS, the client was suppose to
do this, but we always ended up with mixed EOL styles. In Subversion, I can
make sure shell scripts have the UNIX EOL style set. I can also use hooks to
lock branches when they aren't in use (it's much harder to do in CVS), and
developers can easily find their change set and back out their changes.

We do continuous builds, and CVS taking 30 to 40 minutes to label was
hurting our ability to build after every change. Subversion can tag a build
in less than a second. What use to take 50 minutes now can be done in 10
minutes. And, really I don't even need to create a tag if I know the
Subversion revision number.

There's little things like a developer being able to see a list of branches
and tags without having to examine every file in the repository. What use to
take 20 minutes in CVS can be done in a few seconds in Subversion.

Subversion and CVS use similar workflows, so they're fairly compatible in
that area. We didn't have to completely redo our entire build infrastructure
because we changed from CVS to Subversion. Something that you might have to
do if you moved to say ClearCase.

To me, if you're using CVS, you might as well upgrade to Subversion. CVS has
had no active development in the last decade. Subversion has replaced CVS in
that respect.
