Read repo-info from /etc/cgitrc
This makes cgit read all repo-info from the configfile, instead of scanning for possible git-dirs below a common root path. This is primarily done to get better security (separate physical path from logical repo-name). In /etc/cgitrc each repo is registered with the following keys: repo.url repo.name repo.path repo.desc repo.owner Note: *Required keys are repo.url and repo.path, all others are optional *Each occurrence of repo.url starts a new repository registration *Default value for repo.name is taken from repo.url *The value of repo.url cannot contain characters with special meaning for urls (i.e. one of /?%&), while repo.name can contain anything. Example: repo.url=cgit-pub repo.name=cgit/public repo.path=/pub/git/cgit repo.desc=My public cgit repo repo.owner=Lars Hjemli repo.url=cgit-priv repo.name=cgit/private repo.path=/home/larsh/src/cgit/.git repo.desc=My private cgit repo repo.owner=Lars Hjemli Signed-off-by: Lars Hjemli <hjemli@gmail.com>
