From 94cc355287a7efc3eda76af6ae31f503a1ac098b Mon Sep 17 00:00:00 2001 From: Alex Riesen Date: Sun, 26 Oct 2008 23:07:24 +0100 Subject: [PATCH] Fix mkpath abuse in dwim_ref and dwim_log of sha1_name.c Otherwise the function sometimes fail to resolve obviously correct refnames, because the string data pointed to by "str" argument were reused. The change in dwim_log does not fix anything, just optimizes away strcpy code as the path can be created directly in the available buffer.
