Subject: [PATCH v5 37/44] builtin-am: rerere support
Date: Tue, 7 Jul 2015 22:20:55 +0800 [thread overview]
Message-ID: <1436278862-2638-38-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1436278862-2638-1-git-send-email-pyokagan@gmail.com>
git-am.sh will call git-rerere at the following events:
* "git rerere" when a three-way merge fails to record the conflicted
automerge results. Since 8389b52 (git-rerere: reuse recorded resolve.,
2006-01-28)
* Since cb6020b (Teach --[no-]rerere-autoupdate option to merge,
revert and friends, 2009-12-04), git-am.sh supports the
--[no-]rerere-autoupdate option as well, and would pass it to
git-rerere.
* "git rerere" when --resolved, to record the hand resolution. Since
f131dd4 (rerere: record (or avoid misrecording) resolved, skipped or
aborted rebase/am, 2006-12-08)
* "git rerere clear" when --skip-ing. Since f131dd4 (rerere: record (or
avoid misrecording) resolved, skipped or aborted rebase/am,
2006-12-08)
* "git rerere clear" when --abort-ing. Since 3e5057a (git am --abort,
2008-07-16)
Re-implement the above in builtin/am.c.
