Mediawiki

Mediawiki is the wiki software powering wikipedia. It can fairly easily be made to work with Raven. The Computing Service has been using a Raven-enabled copy of Mediawiki internally for some time. CARET have a Raven-enabled copy of Mediawiki that is available to the university - see http://wiki.caret.cam.ac.uk/

Software hacks, 1.5.2

These hacks all assume that the Mediawiki application is first protected by something that sets the REMOTE_USER apache server variable, such as the Raven Apache authentication module.

User.php

Line 60, newFromName, replace:

$t = Title::newFromText( $name ); 

with:

$t = Title::newFromText( $name , NS_USER ); 

To explicitly specify the namespace. This will be used to check in the hack in Title.php, below.

Line 153, idFromName:

$s = $dbr->selectRow( 'user', array( 'user_id' ), array( 'user_name' => $name ), $fname );

... and in the function loadFromSession():

if ( isset( $_SERVER["REMOTE_USER"] ) ) {
  $sName = $_SERVER["REMOTE_USER"];
  $sId = User::idFromName($sName);
  $user = new User();
  if ( $sId == 0 ) {
    /* User doesn't exist here yet.  */
    $user->setName($sName);
    $user->addToDatabase();
  } else {
    $user->mId = $sId;
    $user->loadFromDatabase();
  }
  return $user;
}            

Title.php

Stop the first letter of userpages being capitalised, so we can stick with CRSIDs being all lowercase everywhere. To do this, in the (private) function function secureAndSplit(), replace:

if( $wgCapitalLinks && $this->mInterwiki == '' ) {          
  $t = $wgContLang->ucfirst( $r );
} else {
  $t = $r;                 
}             

With:

if( $wgCapitalLinks && $this->mInterwiki == '' && NS_USER != $this->mNamespace ) {          
  $t = $wgContLang->ucfirst( $r );
} else {
  $t = $r;                 
}
