 145 ## Permission settings
 146
 147 # Note that if you are going to need the fixup root cronjob
 148 # ($chrooted and $permission_control eq 'Group'), you need to update
 149 # the settings in jobs/fixup.sh as well.
 150
 151 # Girocco needs some way to manipulate write permissions to various parts of
 152 # all repositories; this concerns three entities:
 153 # - www-data: the web interface needs to be able to rewrite few files within
 154 # the repository
 155 # - repo: a user designated for cronjobs; handles mirroring and repacking;
 156 # this one is optional if not $mirror
 157 # - others: the designated users that are supposed to be able to push
 158
 159 # There are several ways how to use Girocco based on a combination of the
 160 # following settings.
 161
 162 # (Non-chroot) UNIX user the CGI scripts run on
 163 our $cgi_user = 'www-data';
 164
 165 # (Non-chroot) UNIX user performing mirroring jobs
 166 our $mirror_user = 'repo';
 167
 168 # (Non-chroot) UNIX group owning the repositories by default; it owns whole
 169 # mirror repositories and at least web-writable metadata of push repositories.
 170 # If you undefine this, all the data will become WORLD-WRITABLE.
 171 our $owning_group = 'repo';
 172
 173 # Whether to use chroot jail for pushing; this must be always the same
 174 # as $manage_users.
 175 # TODO: Gitosis support for $manage_users and not $chrooted?
 176 our $chrooted = $manage_users;
 177
 178 # How to control permissions of push-writable data in push repositories:
 179 # * 'Group' for the traditional model: The $chroot/etc/group project database
 180 #   file is used as the UNIX group(5) file; the directories have gid appropriate
 181 #   for the particular repository and are group-writable. This works only if
 182 #   $chrooted so that users are put in the proper groups on login. This requires
 183 #   you also to set up the very crude fixup.sh cronjob for root.
 184 # * 'ACL' for a model based on POSIX ACL: The directories are coupled with ACLs
 185 #   listing the users with push permissions. This works for both chroot and
 186 #   non-chroot setups, however it requires ACL support within the filesystem.
 187 #   This option is BASICALLY UNTESTED, too. And UNIMPLEMENTED. :-)
 188 # * 'Hooks' for a relaxed model: The directories are world-writable and push
 189 #   permission control is purely hook-driven. This is INSECURE and works only
 190 #   when you trust all your users; on the other hand, the attack vectors are
 191 #   mostly just DoS or fully-traceable tinkering.
 192 our $permission_control = 'Group';
