Your fundamental question "why" - well it is for a Python rework of the old "cvsstat" I wrote many years ago -> http://cvs.sslug.dk/cvs2html/ [3] i.e. in order to answer "why do I get if I would update?" - very relevant question IMHO. * cvs lrs -> NICE one - I will check this one out - never used it * cvs log -> I want to avoid this since I normally have quite big projects, i.e. cvs log will give a lot of output.

And commonly done poorly. eg: Eclipse 'syncronise' and Oracle JDeveloper. At least in the case or Oracle, the JDeveloper team did contact us at some point to ask suggestions of how to do it 'better'.

Typically this answer is not well liked.

I mostly work on CVSNT (forked from CVS several years ago to support additional features), and I know that in many cases cvsnt 'cvs -n' does not do what it is advertised to do. In fact we only 'support' a couple of specific cases of 'cvs -n up' since we consider it an 'outdated/deprecated' way to 'list modules'. After 7 years and about 7 million downloads we've only ever had 1 person notice - and they were a CVS developer (GUI) not a 'person using CVS'. My point? 'cvs -n' is not widely used and therefore probably not widely tested. > > Regards, > > Arthur Barrett > > -----Original Message----- > From: [email protected] [1] on behalf of Peter Toft > Sent: Thu 07/07/2011 7:45 AM > To: Info cvs > Cc: > Subject: How to detect new CVS dirs > > Hi all > > I have a small brain-teaser for the CVS-gurus.... > > Assume > that I "pto" have a CVS module checked out, and the user "donald" have > the same module checked out - > > both on HEAD version.
