As a happy modem user of cvsup, I shudder at the idea of deleting the whole source tree whenever I change labels... - Mike H.

All of those files previously existed. The short answer is that it checks out new copies whenever it realizes that it can't update the file properly by applying diffs alone. The reasons for that are complicated, but the fact that you changed the tag has something to do with it. > And by setting the mtime for UPDATING to Sep 14, there's the > possibility of the above pitfall you describe.

I suspect that when CVSup gives up on applying diffs and checks out a fresh copy instead, it forgets that the file should be touched instead of receiving the timestamp of the revision. I have made a note in my to-do file to look into this. But, whenever you switch tags you should most likely delete your /usr/obj tree anyway, just as a matter of safety. John -- John Polstra John D.
