  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 that, ideally, all information used to instantiate service objects should come
  31  * from configuration. Information derived from the current request is acceptable, but
  32  * only where there is no feasible alternative. It is preferred that such information
  33  * (like the client IP, the acting user's identity, requested title, etc) be passed to
  34  * the service object's methods as parameters. This makes the flow of information more
  35  * obvious, and makes it easier to understand the behavior of services.
  36  *
  37  * @note As of version 1.27, MediaWiki is only beginning to use dependency injection.
  38  * The services defined here do not yet fully represent all services used by core,
  39  * much of the code still relies on global state for this accessing services.
  40  *
  41  * @since 1.27
  42  *
  43  * @see docs/injection.txt for an overview of using dependency injection in the
  44  *      MediaWiki code base.
