From 72ec8ba6dddbe2c53500d35d7ed343c153874fc6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 14 Feb 2010 22:44:44 +0700 Subject: Support working directory located at root MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Git should work regardless where the working directory is located, even at root. This patch fixes two places where it assumes working directory always have parent directory. In setup_git_directory_gently(), when Git goes up to root and finds .git there, it happily sets worktree to "" instead of "/". In prefix_path(), loosen the outside repo check a little bit. Usually when a path XXX is inside worktree /foo, it must be either "/foo", or "/foo/...". When worktree is simply "/", we can safely ignore the check: we have a slash at the beginning already. Not related to worktree, but also set gitdir correctly if a bare repo is placed (insanely?) at root. Thanks João Carlos Mendes Luís for pointing out this problem.
