Regexp wgWhitelistRead

Regular Expressions for wgWhitelistRead

The function userCanRead() in includes/Title.php has been changed (similar to the hack for wgWhitelistEdit) like this:

        function userCanRead() {
                global $wgUser;
                if( $wgUser->isAllowed('read') ) {
                        return true;
                } else {
                        global $wgWhitelistRead;
                        /** If anon users can create an account,
                            they need to reach the login page first! */
                        if( $wgUser->isAllowed( 'createaccount' )
                            && $this->getNamespace() == NS_SPECIAL
                            && $this->getText() == 'Userlogin' ) {
                                return true;
                        }
                        /** some pages are explicitly allowed */
                        $name = $this->getPrefixedText();
                        # The following 3 lines have been replaced ...
                        # if( in_array( $name, $wgWhitelistRead ) ) {
                        #       return true;
                        # }
                        # ... with the following code to have regular expressions in wgWhitelistRead
                        if ( is_array($wgWhitelistRead) ) {
                                for ($i=0; $i<count($wgWhitelistRead); $i++) {
                                        if (preg_match($wgWhitelistRead[$i],$name)) {
                                                return true;
                                        }
                                }
                        }
                        # Compatibility with old settings
                        if( $this->getNamespace() == NS_MAIN ) {
                                if( in_array( ':' . $name, $wgWhitelistRead ) ) {
                                        return true;
                                }
                        }
                }
                return false;
        }

Afterwards one can use regular expressions in the file LocalSettings.php for specifying private pages or namespaces, which only can be read by authentified users:

# Specify who can edit: true means only logged in users may edit pages
$wgWhitelistEdit = true;
# Pages anonymous (not-logged-in) users may see
$wgWhitelistRead = array ("/^[^:]*$/", "/^Special:(Search|Categories)$/", "/^(Help|Image|User|Category|MMVLWiki):/" );
# Specify who may create new accounts: 0 means no, 1 means yes
$wgWhitelistAccount = array ( 'user' => 0, 'sysop' => 1, 'developer' => 1 );
$wgShowIPinHeader = false; # For non-logged in users
