Andreas, Andreas' point about storing diffs in SCM archives is correct. There are several SCM tools that do not store revisions as diffs but store entire files. Dimensions being one. On demand diffing between revisions and merging are orthogonal to how revisions are natively stored in the SCM repository. scott -----Original Message----- From: cvsnt-bounces at cvsnt.org [mailto:cvsnt-bounces at cvsnt.org] On Behalf Of Tony Hoyle Sent: Wednesday, June 07, 2006 8:14 AM To: cvsnt at cvsnt.org cvsnt downloads at march-hare.com @CVSNT on Twitter CVSNT on Facebook Subject: Re: [cvsnt] Re: Branch merging - this seems wrong...

Merging works by taking the difference between the common revision (branchpoint or mergepoint) and the latest revision on the branch. That diff is then applied to the target branch. Only 1 diff and 1 revision are used in that process. Normally diff3 is not used, unless the client copy has changed, in which case it's used to more intelligently handle the conflict cases. If you get the wrong common revision as you want to do you *lose* all the changes made before that revision as they are not already in the target branch.
