From a03ceba68830fd5112ce33db7f933e763ffdf7f2 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sat, 9 Jul 2011 19:14:54 +0200 Subject: [PATCH] Do not trust PWD blindly At least on Windows, chdir() does not update PWD. Unfortunately, stat() does not fill any ino or dev fields anymore, so get_pwd_cwd() is not able to tell. But there is a telltale: both ino and dev are 0 when they are not filled correctly, so let's be extra cautious. This happens to fix a bug in "get-receive-pack working_directory/" when the GIT_DIR would not be set correctly due to absolute_path(".") returning the wrong value.
