[edit] What can this extension do?

The extension DeletePagePermanently adds a new tab that allows you to delete a page permanently from the database. I advise you to test carefully the extension and backup your database as the extension is in beta status.

This extension does NOT delete Template pages.

[edit] Download instructions

Please cut and paste the code found below and place it in $IP/extensions/DeletePagePermanently/DeletePagePermanently.php and DeletePagePermanently.i18n.php. Note: $IP stands for the root directory of your MediaWiki installation, the same directory that holds LocalSettings.php.

[edit] Installation

The extension was designed for MediaWiki 1.13 but it should be compatible with other MediaWiki version as long as the database layout is the same as MediaWiki 13.0 for the tables page_restrictions, revision, text, revision, page and recentchanges. However the extension seems to be compatible with MediaWiki 11.0+ or 1.12+ because of the use of wfLoadExtensionMessages which seems to be introduced in 1.11 or even only 1.12alpha.

To install this extension, add the following to LocalSettings.php:

require_once("$IP/extensions/DeletePagePermanently/DeletePagePermanently.php");
#add configuration parameters here
#setup user rights here

[edit] User rights

The extension introduces a new user rights deleteperm.

Defaults from DeletePagePermanently.php:

$wgGroupPermissions['*']         ['deleteperm'] = false;
$wgGroupPermissions['user']      ['deleteperm'] = false;
$wgGroupPermissions['bureaucrat']['deleteperm'] = false;
$wgGroupPermissions['sysop']     ['deleteperm'] = true;
