Bug#659350: git reflog should track branch deletions/re-creations

[Hugues Hiegel]

Package: git
Version: 1:1.7.8.3-1
Severity: normal

Hello all,

When deleting a ref, the whole reflog for this ref is also deleted,
disallowing users to track for a branch deletion/re-creation.
(Very useful on a shared repository, for example)

Instead, I suggest that reflogs are never removed, but simply updated
with a **deleted** message.
Alongside, git reflog should get a prune subcommand which will allow
the user to remove stale logs after ref deletions.

Best regards,
Hugues Hiegel

While there are subtleties, I agree with the general premise.

See [1] and the surrounding thread (especially [3]!) for some
pointers, and feel free to raise this on the g...@vger.kernel.org list,
cc-ing me, if you have time to work on it.  (No subscription required,
since the convention is to always reply-to-all there.)

One way to move forward might be to test Clemens's patch on top of a
more current git and report on what details feel awkward or seem to
remain to be done before it is ready for mass consumption, so
interested others can help to move it forward.

Thanks very much for this, and good luck.

Sincerely,
Jonathan
