From 7ebac8cb94f3a06d3fbdde469414a1443ca45510 Mon Sep 17 00:00:00 2001 From: Adam Roben Date: Tue, 5 Jun 2012 10:24:11 -0400 Subject: [PATCH] Fix launching of externals from Unicode paths If Git were installed in a path containing non-ASCII characters, commands such as git-am and git-submodule, which are implemented as externals, would fail to launch with the following error: > fatal: 'am' appears to be a git command, but we were not > able to execute it. Maybe git-am is broken? This was due to lookup_prog not being Unicode-aware. It was somehow missed in 2ee5a1a14ad17ff35f0ad52390a27fbbc41258f3. Note that the only problem in this function was calling GetFileAttributes instead of GetFileAttributesW. The calls to access() were fine because access() is a macro which resolves to mingw_access, which already handles Unicode correctly. But I changed lookup_prog to use _waccess directly so that we only convert the path to UTF-16 once.
