  22  * This file is loaded by MediaWiki\MediaWikiServices::getInstance() during the
  23  * bootstrapping of the dependency injection framework.
  24  *
  25  * This file returns an array that associates service name with instantiator functions
  26  * that create the default instances for the services used by MediaWiki core.
  27  * For every service that MediaWiki core requires, an instantiator must be defined in
  28  * this file.
  29  *
  30  * @note As of version 1.27, MediaWiki is only beginning to use dependency injection.
  31  * The services defined here do not yet fully represent all services used by core,
  32  * much of the code still relies on global state for this accessing services.
  33  *
  34  * @since 1.27
  35  *
  36  * @see docs/injection.txt for an overview of using dependency injection in the
  37  *      MediaWiki code base.
