injection txt This is an overview of how MediaWiki makes use of dependency injection The design described here grew from the discussion of RFC T384 The term dependency this means that anything an object needs to operate should be injected from the the object itself should only know narrow no concrete implementation of the logic it relies on The requirement to inject everything typically results in an architecture that based on two main types of and essentially stateless service objects that use other service objects to operate on the value objects As of the beginning MediaWiki is only starting to use the DI approach Much of the code still relies on global state or direct resulting in a highly cyclical dependency which acts as the top level factory for services in MediaWiki which can be used to gain access to default instances of various services MediaWikiServices however also allows new services to be defined and default services to be redefined Services are defined or redefined by providing a callback the instantiator that will return a new instance of the service When it will create an instance of MediaWikiServices and populate it with the services defined in the files listed by thereby bootstrapping the DI framework Per $wgServiceWiringFiles lists includes ServiceWiring php

linkcache txt The LinkCache class maintains a list of article titles and the information about whether or not the article exists in the database This is used to mark up links when displaying a page If the same link appears more than once on any page then it only has to be looked up once In most cases link lookups are done in batches with the LinkBatch class or the equivalent in so the link cache is mostly useful for short snippets of parsed and for links in the navigation areas of the skin The link cache was formerly used to track links used in a document for the purposes of updating the link tables This application is now deprecated To create a you can use the following $titles
