From 9459aa77a032621a29d53605542844641cca843a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Wed, 5 Dec 2007 20:33:32 +0700 Subject: [PATCH] Do check_repository_format() early (re-fix) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This pushes check_repository_format() (actually _gently() version) to setup_git_directory_gently() in order to prevent from using unsupported repositories. New setup_git_directory_gently()'s behaviour is stop searching for a valid gitdir and return as if there is no gitdir if a unsupported repository is found. Warning will be thrown in these cases.
