Subject: [PATCH 15/18] reset: Make reset remove the sequencer state
Date: Tue, 19 Jul 2011 22:47:53 +0530 [thread overview]
Message-ID: <1311095876-3098-16-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1311095876-3098-1-git-send-email-artagnon@gmail.com>
Years of muscle memory have trained users to use "git reset --hard" to
remove the branch state after any sort operation. Make it also remove
the sequencer state to facilitate this established workflow:
$ git cherry-pick foo..bar
... conflict encountered ...
$ git reset --hard # Oops, I didn't mean that
$ git cherry-pick quux..bar
... cherry-pick succeeded ...
Guard against accidental removal of the sequencer state by providing
one level of "undo". In the first "reset" invocation,
".git/sequencer" is moved to ".git/sequencer-old"; it is completely
removed only in the second invocation.
