Extension:DeletePagePermanently

This extension can delete pages in every namespace configured (also images) without leaving any trace in the database.

I improved the original Version of Ludovic MOUTON. The original Version can be found at Extension:DeletePagePermanently/1.0

The extension DeletePagePermanently adds a new tab that allows you to delete a page permanently from the database. '''Although version 2.0 is safer than version 1.0 it can still harm your wiki, especially when used wrong. I advise you to test the extension carefully and backup your database as the extension is still in beta status.'''

Installation
The extension was designed for MediaWiki 1.13 but it should be compatible with later version as long as the database layout is the same as MediaWiki 1.13.0 for the tables.

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

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

User rights
The extension introduces a new user rights deleteperm. You can configure the rights in LocalSettings.php:

Defaults from DeletePagePermanently.php:

Namespaces
New in version 2.0 is the possibility to configure the namespaces in which pages can be deleted. To configure this, add some lines to your LocalSettings.php:
