Re: Can the -D option be used on a branch?

If you specify both a specific revision and a specific date, I don't see how you would know *what* to expect. Mixing -D with -r tag is an intersection operation. If -r tag -D date specifies a specific version and specific date, then you should expect the intersection of the specific revision and the specific date. That is, any file in the module for which the commit time of the specific version tag matches the specified date should be checked out. This is probably not very useful unless you specify the time down to the second... This is the same kind of intersection operation you expect when you ask for a specific time on a specific branch. That is, what was the last committed version that was visible on the branch at the specified time? If a given branch does not happen to have any revisions on the branch before the specified time, no version of that particular file is visible (as when adding new files to a branch after the branch was originally created). If the branch contains a version with the dead state as the last commit before the specific time, then the file is also not to be checked out. For the purpose of an intersection operation, a specific version is just as if a branch happened to have a commit happen exactly one second after the first commit to the branch. So, the specific version may be considered as a degenerate case of a branch. There are likely to be very few instances where this particular intersection would be useful: A) given that all commits during a single cvs commit operation have the same commit time, it would be possible to determine all of the commits that were atomic across the given repository at that specific time which were also tagged with a particular version tag and checkout just those files. B) given a 'cvs import -d' that preserved date and time, it might be possible to examine all of the files that were modified in the original sources at a particular time by intersection of the import tag with the specific time indication.

Sometimes it means a branch, and sometimes it means an exact revision. I.e.: -r branch_tag -D date is useful, whereas: -r revison_tag -D date is nonsense. -Russ ___ Info-cvs mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/info-cvs

you can use -D with -r tag, but sometimes it is confusing. if tag is a simple tag, and not a branch tag, you might not get what you expect. -Russ At 10:56 PM -0700 4/11/01, David L.

It would be nice for tag/rtag to accept both options as well. (But one could always tag following checkout with both options and achieve essentially the same result).

I'd like to be able to checkout from a branch but take revisions that are older than a specified date. Since the -D and -r are both sticky, they apparently cannot be used in combination. Does anyone know of a workaround or combination of commands to do this? Also, does the -D option only apply to trunk revisions?
