Subject: [PATCH 38/47] Use git_config_early() instead of git_config() during repo setup
Date: Fri, 26 Nov 2010 22:32:34 +0700 [thread overview]
Message-ID: <1290785563-15339-39-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1290785563-15339-1-git-send-email-pclouds@gmail.com>
When git_config() is called, either git_dir has already been set (by
$GIT_DIR env or set_git_dir()), or it will default git_dir to ".git".
git_config_early() gives setup functions more freedom because it does
not require git_dir. Give it a config path, it will happily examine
it.
