From 95eb88d8ee588d89b4f06d2753ed4d16ab13b39f Mon Sep 17 00:00:00 2001 From: Ramkumar Ramachandra Date: Thu, 4 Aug 2011 16:09:12 +0530 Subject: [PATCH] reset: Make reset remove the sequencer state 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.
