Subject: [PATCH 03/10] ll_merge(): add ancestor label parameter for diff3-style output
Date: Mon, 15 Mar 2010 02:52:37 -0500 [thread overview]
Message-ID: <20100315075237.GC8824@progeny.tock> (raw)
In-Reply-To: <20100315074748.GA28827@progeny.tock>
Various commands using the ll_merge() function present conflict hunks
in output something like what ‘diff3 -m’ produces if the
merge.conflictstyle configuration option is set to diff3.
Unfortunately, the format is not fully compatible yet. ‘diff3’
includes the name of the merge base on the ||||||| line of the output,
and some tools are reported to misparse the conflict hunks without it.
Add a new ancestor_label parameter to ll_merge() to give callers the
power to rectify this situation. Let all callers pass NULL as that
parameter for now to avoid distracting changes in behavior when
testing this interface change.
