Re: Branch Tag Deleted, Can it be Re-created?

Yes, the 'cvs admin -n' command will work.  I tried it on a couple files.
This is the only branch that is unattached.  Any ideas on how to find the branch revisions not currently attached to a branch tag and reattach them?
Also, what version of CVS will give you warnings when trying to delete a branch?  Would this version have to be on the server or client?

It can be done with some shell scripting and judicious application of
`cvs admin -n', especially if you have a workspace sitting around that
was checked out from the branch that was deleted. If you don't have a
workspace checked out from the branch, the math can be quite painful and
there's not necessarily an automated way to determine exactly which
revisions the branch tag was removed from, unless maybe this is the only
branch you've ever deleted and you can use a script to search for any
branch revisions not currently attached to a branch tag and reattach it.

If you have a backup of the repository from some time in the past, you
might also be able to use that along with `cvs admin -n' to reattach the
tags to the branches.

In general, restoring branches is a very hard problem. It's much easier
to not delete them in the first place, hence all the warnings a recent
version of CVS will give you when you try.
