If the user can write to the repository, they can change any tags.
The simplest thing is probably just to tell your users: "don't change
release tags after they're made."

You could have a separate repository, writable only by release
managers, that contains the definitive tags.

You could do a patch to bzr that runs a hook before tag changes are
attempted, and then use that to enforce a policy about who can change
them. We can help you add the hook if you want to try this.

Hi Martin,

This hook method sounds good, could you please guide me to write a hook for this.

Thanks & Regards,
Vijay

could you help us in setting up hooks for protecting tag deletion.

You would probably want to add the hook in bzrlib/tag.py in the bzr source code, and tests to see that those hooks actually get run in bzrlib/tests/test_tag.py. There are several good examples of hooks in bzrlib/branch.py.

Could you please more specific..
1. copy the script tag.py from ../bzrlib/tag.py to source code repository ?

Repository contains, .bzr/branch
                                        .bzr/branch-lock
                                        .bzr/repository
Where to copy that script and how to test it?

Do I need to modify that tag.py to protect tag deletion?

No, there's no need need to copy anything.

You will need to edit the bzrlib/tag.py file from the bzr source
distribution to add support for hooks (it doesn't exist yet). This will
involve python programming.
