From 0b35deb378ee471f64e1b376d722e0bdd97d5e36 Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Thu, 11 Aug 2011 23:19:45 -0600 Subject: [PATCH] t6036: criss-cross + rename/rename(1to2)/add-source + modify/modify This is another challenging testcase trying to exercise the virtual merge base creation in the rename/rename(1to2) code. A testcase is added that we should be able to merge cleanly, but which requires a virtual merge base to be created that is aware of rename/rename(1to2)/add-source conflicts and can handle those.
