Subject: [PATCH 15/16] alias: keep repository found while collecting aliases as long as possible
Date: Thu, 11 Mar 2010 20:22:33 +0700	[thread overview]
Message-ID: <1268313754-28179-16-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1268313754-28179-1-git-send-email-pclouds@gmail.com>

In order to read aliases, $GIT_CONFIG/config must be read (if found).
Currently, after alias handling is done, we chdir() back to original
cwd, pretending no repository setup is done.

Given plain chdir() is not a proper way to undo
setup_git_directory_gently(), and 80% builtin commands will need to
search for a repository, we could keep the repository found in alias
handling code. Until we are clear, there's no need for a repository,
then we can undo the setup with unset_git_directory().
