[Mediawiki-l] [quickhack] require a specific user to view a page

[Moritz Karbach]

Hi,

as my very private Wiki grew larger, a few people liked to use it as well. So 
I needed to protect the sites, that are really private. Since some kind of 
user rights is scheduled for version 1.5, here comes a quickhack:

Wiki Version: 1.3.5 (maybe it works on later versions as well)

Insert the following into Title.php, function  userCanRead(), right after the 
globals have been defined (for me it's line 550):

                # inserted by m:o
                global $wgRequireUser;
                $siteName = $this->getPrefixedText(); # pagename
                $requiredUser = $wgRequireUser[$name];
                $allowed = true;
                foreach(  $wgRequireUser as $siteRegExp => $requiredUser )
                {
                        $check= preg_match("/$siteRegExp/", "$siteName");
                        
                        if( $check==1 && $wgUser->getName()!=$requiredUser ) 
                        {
                                $allowed = false;
                        }
                }
                if( ! $allowed ) return false;
                # /inserted by m:o

Then insert the following in your LocalSettings.php at the end, just before 
the '?>':

#
# inserted by m:o
#
# set access rights
#
# usage:
# "regular expression that matches the site you want to protect" => "required 
user"
#
# examples:
# "^Linux"  matches all sites beginning with "Linux"
# "Linux"   matches all sites containing "Linux"
# "Linux$"  %                 ending with "Linux"
#
$wgRequireUser = array (
        "^Hauptseite:private$" => "Mo",
        "^Tbd$" => "Mo",
        "^Desy" => "Mo",
        "^Grid" => "Mo",
        "^Logbook$" => "Mo"
);


Maybe someone can comment on possible disadvantages or security holes?

Cheers,
