Hello all!
I have a medium cvs experience, i know how to delete a tag(cvs rtag -d), but
when i delete a
branch(cvs rtag -d my_branch my_module), i receive following message:
[...skip...]
W /home/cvs/nausite/my_module/file1.tmp,v : my_branch is branch tag : NOT
DELETING
W /home/cvs/nausite/my_module/file2.tmp,v : my_branch is branch tag : NOT

What am i doing wrong? and Is deleting a branch a safe operation for
repository?
From rtag help:
------------------------
Usage: cvs rtag [-abdFflnR] [-r rev|-D date] tag modules...
-d Delete the given tag.
-F Move tag if it already exists.
!! -B Allow move/delete of branch tag (not recommended). !!
------------------------
Use with caution.
And only when you really need it.
If you delete a branch while it is still active (i.e. 'cvs update -r
branch' followed by 'cvs tag -Bd branch') you may get strange behaviour.
Make sure nobody has the files checked out on the branch before removing
its tag.
> I think it is dangerous because it perminantly
removes all revisions on the branch (physically deletes them from the
repository). So be sure you want to remove them. The difference is
that a regular tag just points to or references a version (MY_TAG=1.3
for myfile.txt) so deleting a regular tag just removes the reference.
Whereas a branch tag creates a new branch on the tree where revisions
live. Removing the branch removes the home for the revisions and they
are lost in the ether floating aimlessly...
How dramatic! And fortunately, how incorrect ;=)
The only thing that is lost is the convenient way to reference the
branch. All the revisions are still there, with complete history:
