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

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 also

docs/injection.txt for an overview of using dependency injection in the MediaWiki code base.
