I cvsup at least twice. If I get no changes the second time, I'm
reasonably certain that what I have is not a mid-commit snapshot.
Of course, I don't do this every night, or even every week--that
might be a bit abusive to the mirror.
When Subversion comes out (authored by many of the same fine folks
who brought you CVS, in an effort to do away with the myriad hacks
that comprise CVS), it will support atomic commits, which will neatly
do away with the "I checked out my sources in the middle of someone
else's commit" problem. I don't know if the FreeBSD Project will
switch (I've heard rumblings about Perforce), but I personally (as RE
at my company) will be taking a very long look at Subversion, in the
hopes that it will solve many of the gripes that people have with CVS
(it'll also save me from doing a lot of scripting hacks to add
quasi-transactional behavior on top of CVS).
A big thank-you to Keith Bostic as well: Subversion is built atop
Berkeley DB.
