 * This file is loaded by MediaWiki\MediaWikiServices::getInstance() during the
 * bootstrapping of the dependency injection framework.
 *
 * This file returns an array that associates service name with instantiator functions
 * that create the default instances for the services used by MediaWiki core.
 * For every service that MediaWiki core requires, an instantiator must be defined in
 * this file.
 *
 * Note that, ideally, all information used to instantiate service objects should come
 * from configuration. Information derived from the current request is acceptable, but
 * only where there is no feasible alternative. It is preferred that such information
 * (like the client IP, the acting user's identity, requested title, etc) be passed to
 * the service object's methods as parameters. This makes the flow of information more
 * obvious, and makes it easier to understand the behavior of services.
 *
 * @note As of version 1.27, MediaWiki is only beginning to use dependency injection.
 * The services defined here do not yet fully represent all services used by core,
 * much of the code still relies on global state for this accessing services.
 *
 * @since 1.27
 *
 * @see docs/Injection.md for an overview of using dependency injection in the
 *      MediaWiki code base.
