Subject: [PATCH 10/17] sequencer: Announce sequencer state location
Date: Mon, 11 Jul 2011 14:54:01 +0000 [thread overview]
Message-ID: <1310396048-24925-11-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1310396048-24925-1-git-send-email-artagnon@gmail.com>
The plan to build a generic sequencer involves fist writing the
functionality into builtin/revert.c (for cherry-pick and revert), and
then factoring it out into sequencer.c and exposing it through
sequencer.h as a nice API. As a prelude to this, announce the
location of the sequencer state in sequencer.h and write a function to
remove it. Later in the series, two indepenent Git programs, namely
cherry-pick/ revert and reset, will use this to save and clear
sequencer state in a uniform manner.
