Here is v3. It is also available on GitHub [1]. Thanks to Junio and Brad for their comments about v2. I think I have addressed all of your comments (except for Junio's regrets that the series didn't include a transactional receive-pack). See the mailing list threads about v1 [2] and v2 [3] and the longer-term goals of this campaign [4]. Changes since v2: * Rebased to current master (there were no conflicts) * Don't allow ref_transation_create() with new_sha1 set to zeros. * Don't allow ref_transation_delete() with old_sha1 set to zeros. * Fixed subject lines to use lower-case after the colon. * Expanded a few commit messages, fixed a comment, and removed some "squash" detritus in a commit message.
