From 542c264b01ac551dca0697d6577ec71ad4c245ab Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 10 Mar 2008 01:26:23 -0700 Subject: [PATCH] traverse_trees_recursive(): propagate merge errors up There were few places where merge errors detected deeper in the call chain were ignored and not propagated up the callchain to the caller. Most notably, this caused switching branches with "git checkout" to ignore a path modified in a work tree are different between the HEAD version and the commit being switched to, which it internally notices but ignores it, resulting in an incorrect two-way merge and loss of the change in the work tree.
