Detailed Description

This class handles the logic for the actor table migration and should always be used in lieu of directly accessing database tables.

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.

UserIdentity	$user	User to set in the update

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

UserIdentity	$user	User to set in the update

Returns

array with two values:

◆ getJoin()

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

References $t, checkDeprecation(), getFieldNames(), and SCHEMA_COMPAT_READ_OLD.

◆ getNewActorId()

ActorMigration::getNewActorId	(	IDatabase	$dbw,
		UserIdentity	$user
	)

Attempt to assign an actor ID to the given user.

If it is already assigned, return the existing ID.

Since: 1.35.0

Deprecated:: since 1.36. Use ActorStore::acquireActorId instead.

Parameters

IDatabase	$dbw
UserIdentity	$user

Returns: int The new actor ID

Definition at line 283 of file ActorMigration.php.

References Wikimedia\Rdbms\IDatabase\getDomainID(), and wfDeprecated().

◆ getWhere()

ActorMigration::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 three keys:

tables: (string[]) to include in the $table to IDatabase->select()
conds: (string) to include in the $cond to IDatabase->select()
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() All tables and joins are aliased, so + is safe to use.
