doFunctions17()
Recreate functions to 17 schema layout.
purgeCache()
Overload: because of the DDL_MODE tablename escaping is a bit dodgy.
applyPatch( $path, $isFullPath=false, $msg=null)
Applies a SQL patch.
doFKRenameDeferr()
Uniform FK names + deferrable state.
Class for handling database updates.
doPageRestrictionsPKUKFix()
Fixed wrong PK, UK definition.
doRecentchangesFK2Cascade()
Removed forcing of invalid state on recentchanges_fk2.
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
doAutoIncrementTriggers()
Add auto-increment triggers.
Class for handling updates to Oracle databases.
doInsertPage0()
Insert page (page_id = 0) to prevent FK constraint violation.
doRemoveNotNullEmptyDefaults()
Remove DEFAULT '' NOT NULL constraints from fields as '' is internally converted to NULL in Oracle.
doSchemaUpgrade17()
Schema upgrade 16->17 there are no incremental patches prior to this.
doRemoveNotNullEmptyDefaults2()
DatabaseOracle $db
Handle to the database subclass.
getCoreUpdateList()
Get an array of updates to perform on the database.
doNamespaceDefaults()
MySQL uses datatype defaults for NULL inserted into NOT NULL fields In namespace case that results in...
doRebuildDuplicateFunction()
rebuilding of the function that duplicates tables for tests
doUpdates(array $what=[ 'core', 'extensions', 'purge', 'stats'])
Overload: after this action field info table has to be rebuilt.
the array() calling protocol came about after MediaWiki 1.4rc1.
