From 52aaf649cb70134090c3e3a762bed730d5451c17 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 9 Jul 2007 14:47:24 +0100 Subject: [PATCH] rerere: record resolution even if file is not in merge base MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Two-file merges were rare enough that they were dropped outside of the radar. This fix is a trivial change to builtin-rerere.c::find_conflict(). It is still sane to insist that we do not do rerere for symlinks, and require to have stages #2 and #3, but we can drop the requirement to have stage #1. rerere does not use information from there anyway. This fix is from Junio, together with two tests to verify that it works as expected.
