deletion of branch seems to modify tag as well?

deletion of branch seems to modify tag as well?

[Lyons, Roy]

$ git push origin :ABRANCHNAME
remote: Firing Pre - receive hook
remote:
remote:
remote: Firing Post receive hook
remote:
remote: Branch is ABRANCHNAME -- not creating Trigger file since this is not _int branch
remote: error: Trying to write ref refs/tags/ABRANCHNAME!SN-BL-20130605_100513_04363 with nonexistent object 0000000000000000000000000000000000000000
remote: fatal: refs/tags/ABRANCHNAME!SN-BL-20130605_100513_04363: cannot update the ref
To ssh://git@ourgitserver/repositoryname.git
- [deleted] ABRANCHNAME


I would not expect this behavior.  Is git attempting to modify the tags associated to the HEAD commit on the branch in addition to the branch?   If so, I would like to consider this a bug report...



Thanks,

Roy Lyons

I do not think git is doing anything of the sort. The output you see
above comes from custom hooks on the server. We cannot say for certain
without seeing the hook's code, but it looks like the post-receive hook
is trying to create a tag to point to the tip of every push, but whoever
wrote the hook did not take into account branch deletions (and the fact
that you cannot create a tag pointing at a deletion).

Excellent response.  I had not even considered that the hook for creating
these tags would be in the mix.

I withdraw my bug report happily :)


Thanks,
