> From: Tony Hoyle [mailto:tmh at nodomain.org] > > How is CVS to distinguish between the case of the file being > added/committed on Branch2 after it was deleted on branch1 or before? > 2. Repository file not at branch/merge point, file removed on branch > -> warning + leave file alone When a user does a tag or branch, CVS goes through the directory structure and adds a new symbol to the RCS file of every currently active file in the current branch. If it finds a file that was marked as deleted in the current branch it does not add the new symbol to it. So, if that new symbol is used in future, CVS cannot find a revision of that file associated with that symbol. This is fine if doing an update or check-out as it simply does not get (or it deletes) the file. However, as you have pointed out, it causes a problem when merging. If, on the other hand, when doing a tag or branch CVS were to add the new symbol to deleted files too, this would solve this problem. When doing an update or a check-out, the symbol would be associated with a deleted revision and so the file would again not be retrieved (or would be deleted). And now when doing a merge there would be a valid revision (albeit a deleted one) at the branch point. For a file that is added in Branch1 but not in Branch2, you would still get the situation that there is no revision at the branch point. However since this is now the only case were this could happen then you know that the file has been added in Branch1 rather than deleted in Branch2 and can deal with it accordingly.
