From mboxrd@z Thu Jan 1 00:00:00 1970 From: valentin.haenel at gmx.de (Valentin Haenel) Date: Tue, 16 Oct 2012 11:15:25 +0200 Subject: [PATCH 2/3] Add ability to authorize viewing a repository In-Reply-To: <1350378927-10834-1-git-send-email-valentin.haenel@gmx.de> References: <1350378927-10834-1-git-send-email-valentin.haenel@gmx.de> Message-ID: <1350378927-10834-3-git-send-email-valentin.haenel@gmx.de> This provides a mechanism for cgit to query an external program for repository authorisation, e.g. gitolite. An additional config variable 'authorization' contains the path and name of the executable to use.
