   1 Prior to version 1.16, maintenance scripts were a hodgepodge of code that
   2 had no cohesion or formal method of action. Beginning in 1.16, maintenance
   3 scripts have been cleaned up to use a unified class.

   9 1. DIRECTORY STRUCTURE
  10   The /maintenance directory of a MediaWiki installation contains several
  11 subdirectories, all of which have unique purposes.
  12
  13 2. HOW TO RUN A SCRIPT
  14   Ridiculously simple, just call 'php someScript.php' that's in the top-
  15 level /maintenance directory.
  16
  17 Example:
  18   php clearCacheStats.php
  19
  20 The following parameters are available to all maintenance scripts
  21 --help   : Print a help message
  22 --quiet  : Quiet non-error output
  23 --dbuser : The database user to use for the script (if needed)
  24 --dbpass : Same as above (if needed)
  25 --conf   : Location of LocalSettings.php, if not default
  26 --wiki   : For specifying the wiki ID
  27 --batch-size : If the script supports batch operations, do this many per batch
  28
  29 3. HOW TO WRITE YOUR OWN
  30 Make a file in the maintenance directory called myScript.php or something.
  31 In it, write the following:
  32
  33 ==BEGIN==
  34
  35 <?php
  36
  37 require_once 'Maintenance.php';
  38
  39 class DemoMaint extends Maintenance {
  40
  41   public function __construct() {
  42     parent::__construct();
  43   }
  44
  45   public function execute() {
  46   }
  47 }
  48
  49 $maintClass = "DemoMaint";
  50 require_once RUN_MAINTENANCE_IF_MAIN;
  51
  52 ==END==
  53
  54 That's it. In the execute() method, you have access to all of the normal
  55 MediaWiki functions, so you can get a DB connection, use the cache, etc.
