Public Member Functions

__construct ( $stage, ActorStoreFactory $actorStoreFactory)

getInsertValues (IDatabase $dbw, $key, UserIdentity $user)

Get UPDATE fields for the actor.

Parameters

IDatabase	$dbw	Database to use for creating an actor ID, if necessary
string	$key	A key such as "rev_user" identifying the actor field being fetched.
UserIdentity	$user	User to set in the update

Returns: array to merge into $values to IDatabase->update() or $a to IDatabase->insert()

getInsertValuesWithTempTable (IDatabase $dbw, $key, UserIdentity $user)

Get UPDATE fields for the actor.

Parameters

IDatabase	$dbw	Database to use for creating an actor ID, if necessary
string	$key	A key such as "rev_user" identifying the actor field being fetched.
UserIdentity	$user	User to set in the update

Returns

array with two values:

array to merge into $values to IDatabase->update() or $a to IDatabase->insert()
callback to call with the primary key for the main table insert and extra fields needed for the temp table.

getJoin ( $key)

Get SELECT fields and joins for the actor key.

Parameters

string $key A key such as "rev_user" identifying the actor field being fetched.

Returns

array[] With three keys:

tables: (string[]) to include in the $table to IDatabase->select() or SelectQueryBuilder::tables
fields: (string[]) to include in the $vars to IDatabase->select() or SelectQueryBuilder::fields
joins: (array) to include in the $join_conds to IDatabase->select() or SelectQueryBuilder::joinConds All tables, fields, and joins are aliased, so + is safe to use.

getWhere (IDatabase $db, $key, $users, $useId=true)

Get WHERE condition for the actor.

Parameters

IDatabase	$db	Database to use for quoting and list-making
string	$key	A key such as "rev_user" identifying the actor field being fetched.
UserIdentity \| UserIdentity[] \| null \| false	$users	Users to test for. Passing null, false, or the empty array will return 'conds' that never match, and an empty array for 'orconds'.
bool	$useId	If false, don't try to query by the user ID. Intended for use with rc_user since it has an index on (rc_user_text,rc_timestamp) but not (rc_user,rc_timestamp).

Returns

array With four keys:

tables: (string[]) to include in the $table to IDatabase->select() or SelectQueryBuilder::tables
conds: (string) to include in the $cond to IDatabase->select() or SelectQueryBuilder::conds
orconds: (array[]) array of alternatives in case a union of multiple queries would be more efficient than a query with OR. May have keys 'actor', 'userid', 'username'. Since 1.32, this is guaranteed to contain just one alternative if $users contains a single user.
joins: (array) to include in the $join_conds to IDatabase->select() or SelectQueryBuilder::joinConds All tables and joins are aliased, so + is safe to use.

Detailed Description

This is not intended to be a long-term part of MediaWiki; it will be deprecated and removed once actor migration is complete.

Since: 1.31; 1.34 Use with 'ar_user', 'img_user', 'oi_user', 'fa_user', 'rc_user', 'log_user', and 'ipb_by' is deprecated. Callers should reference the corresponding actor fields directly.

Deprecated: since 1.39

Member Function Documentation

◆ getInsertValues()

ActorMigration::getInsertValues	(	IDatabase	$dbw,
			$key,
		UserIdentity	$user )

Get UPDATE fields for the actor.

Parameters

IDatabase	$dbw	Database to use for creating an actor ID, if necessary
string	$key	A key such as "rev_user" identifying the actor field being fetched.
UserIdentity	$user	User to set in the update

Returns: array to merge into $values to IDatabase->update() or $a to IDatabase->insert()

Deprecated: since 1.39 Use ‘[ ’{table_prefix}_actor' => MediaWikiServices::getInstance() ->getActorNormalization()->acquireActorId( $user, $dbw ) ] E.g. for key=log_user, use[ 'log_actor' => ... ]`

◆ getWhere()

ActorMigration::getWhere	(	IDatabase	$db,
			$key,
			$users,
			$useId = true )

Get WHERE condition for the actor.

string	$key	A key such as "rev_user" identifying the actor field being fetched.
UserIdentity \| UserIdentity[] \| null \| false	$users	Users to test for. Passing null, false, or the empty array will return 'conds' that never match, and an empty array for 'orconds'.

Deprecated: since 1.39 Use {table_prefix}_actor IN ({list of actor IDs}). E.g. for key=rev_user, use rev_actor IN ({list of actor IDs}). Use MediaWikiServices::getInstance()->getActorNormalization() ->findActorId( $user, $db ) to get the actor ID for a given user.
