Features

• Permission management through simple edition of a page
  • MediaWiki:Registry/HNP
• Sysop has always all rights regardless of state of registry page
  • Enables easier 'human error' management
• Prefix based namespace access with wildcards
  • E.g. 'sysop group has access to all namespaces'
• Namespace dependant & Namespace Independant rights management
• No additional database tables nor changes to schema
• No mandatory patches
  • Namespace dependant rights management: no patches necessary
  • Namespace independant rights management: if wanted, requires a patch:
    • 'includes/User.php'
• Post-installation information always available through Special:Version page.
• Magic Words:
  • ' #username# ' magic word can be used to substitute the current user's name in the title field
    • Useful for implementing functionality akin to 'KeepYourHandsToYourself' whereas only the owner of a userpage can edit his own

Usage

Please see example configuration page Example.

ISSUES/BUGS

If you receive the "unexpected T_PAAMAYIM_NEKUDOTAYIM, expecting T_NS_SEPARATOR" error in line 423 of extensions/HNP/HNP.body.php, change the "Namespace::" reference to "MWNamespace::". The error will disappear - or at least it did for me. salindley 9 March 2010

User.php patch

Original file

        function isAllowed($action='') {
                if ( $action === '' )
                        // In the spirit of DWIM
                        return true;
 
                return in_array( $action, $this->getRights() );
        }

Patched file

        function isAllowed($action='', $ns = null /* addition */, $title = null /* addition */ ) 
        {
                if ( $action === '' )
                        // In the spirit of DWIM
                        return true;
 
                //  PATCH begin{{
                $result = null;
                wfRunHooks('UserIsAllowed', array( &$this, $ns, $title, &$action, &$result ) );
                if ( $result !== null )
                        return $result;
                // PATCH end }}
 
                return in_array( $action, $this->getRights() );
        }

MEDIAWIKI NOTES

1) Only the forward slash is interpreted (when enabled) as an indicator of "sub-page". Thus, only the forward slash and ~ are considered here to be part of the hierarchical functionality.

2) The allowed characters in a title are defined in "DefaultSettings.php".

  $wgLegalTitleChars = " %!\"$&'()*,\\-.\\/0-9:;=?@A-Z\\\\^_`a-z~\\x80-\\xFF+";
  NOTE that #{}[]| are not part of this list.
 

3) Special command characters for preg_match do not include the following:

  #`'~,@
  Those were tested with preg_quote

4) Be careful not to choose namespace name identifiers too long as the standard limit in Mediawiki is 16characters long.
