getUserIdentityByName (string $name, int $queryFlags=IDBAccessObject::READ_NORMAL)

Returns: UserIdentity|null

Find an identity of a user by $userId.

Parameters

int	$userId
int	$queryFlags	one of IDBAccessObject constants

Returns: UserIdentity|null

newActorFromRow (stdClass $row)

Instantiate a new UserIdentity object based on a $row from the actor table.

newActorFromRowFields ( $userId, $name, $actorId)

Instantiate a new UserIdentity object based on field values from a DB row.

newSelectQueryBuilder ( $dbOrQueryFlags=IDBAccessObject::READ_NORMAL)

Returns a specialized SelectQueryBuilder for querying the UserIdentity objects.

Parameters

IReadableDatabase | int $dbOrQueryFlags The database connection to perform the query on, or one of the IDBAccessObject::READ_* constants.

Member Function Documentation

◆ acquireActorId()

MediaWiki\User\ActorStore::acquireActorId	(	UserIdentity	$user,
		IDatabase	$dbw )

Attempt to assign an actor ID to the given $user.

If it is already assigned, return the existing ID.

Note: If called within a transaction, the returned ID might become invalid if the transaction is rolled back, so it should not be passed outside of the transaction context.

Parameters

UserIdentity	$user
IDatabase	$dbw	The database connection to acquire the ID from. The database must correspond to ActorStore's wiki ID.

Returns: int actor ID greater then 0

Exceptions

CannotCreateActorException if no actor ID has been assigned to this $user

Implements MediaWiki\User\ActorNormalization.

Definition at line 405 of file ActorStore.php.

◆ acquireSystemActorId()

MediaWiki\User\ActorStore::acquireSystemActorId	(	UserIdentity	$user,
		IDatabase	$dbw )

Attempt to assign an ID to an actor for a system user.

If an actor ID already exists, return it.

Note: For reserved user names this method will overwrite the user ID of the existing anon actor.; If called within a transaction, the returned ID might become invalid if the transaction is rolled back, so it should not be passed outside of the transaction context.

Parameters

UserIdentity	$user
IDatabase	$dbw

Returns: int actor ID greater then zero

Exceptions

CannotCreateActorException if the existing actor is associated with registered user.

Access: internal: for use in user account creation only.

Definition at line 498 of file ActorStore.php.

◆ createNewActor()

MediaWiki\User\ActorStore::createNewActor	(	UserIdentity	$user,
		IDatabase	$dbw )

Create a new actor for the given $user.

If an actor with this name already exists, this method throws.

Note: If called within a transaction, the returned ID might become invalid if the transaction is rolled back, so it should not be passed outside of the transaction context.

Parameters

UserIdentity	$user
IDatabase	$dbw

Returns: int actor ID greater then 0

Exceptions

CannotCreateActorException if an actor with this name already exist.

Access: internal: for use in user account creation only.

Parameters

UserIdentity	$actor
IDatabase	$dbw

Returns: bool true on success, false if nothing was deleted.

Returns: UserIdentity|null

Implements MediaWiki\User\UserIdentityLookup.

Definition at line 230 of file ActorStore.php.

◆ newActorFromRow()

MediaWiki\User\ActorStore::newActorFromRow ( stdClass $row )

Instantiate a new UserIdentity object based on a $row from the actor table.

Use this method when an actor row was already fetched from the DB via a join. This method just constructs a new instance and does not try fetching missing values from the DB again, use UserIdentityLookup for that.

Parameters

stdClass

$row

with the following fields:

int actor_id
string actor_name
int|null actor_user

Returns: UserIdentity

Exceptions

InvalidArgumentException

Implements MediaWiki\User\ActorNormalization.

Definition at line 107 of file ActorStore.php.

◆ newActorFromRowFields()

MediaWiki\User\ActorStore::newActorFromRowFields	(	$userId,
		$name,
		$actorId )

Instantiate a new UserIdentity object based on field values from a DB row.

Until ActorMigration is completed, the actor table joins alias actor field names to legacy field names. This method is convenience to construct the UserIdentity based on legacy field names. It's more relaxed with typing then ::newFromRow to better support legacy code, so always prefer ::newFromRow in new code. Eventually, once ActorMigration is completed and all queries use explicit join with actor table, this method will be deprecated and removed.

Exceptions

InvalidArgumentException

Parameters

int \| null	$userId
string \| null	$name
int \| null	$actorId

Returns: UserIdentity

Implements MediaWiki\User\ActorNormalization.

Definition at line 150 of file ActorStore.php.

◆ newSelectQueryBuilder()

MediaWiki\User\ActorStore::newSelectQueryBuilder ( $dbOrQueryFlags = IDBAccessObject::READ_NORMAL )

Returns a specialized SelectQueryBuilder for querying the UserIdentity objects.

Parameters

IReadableDatabase | int $dbOrQueryFlags The database connection to perform the query on, or one of the IDBAccessObject::READ_* constants.

Returns: UserSelectQueryBuilder

Implements MediaWiki\User\UserIdentityLookup.

Definition at line 702 of file ActorStore.php.

◆ normalizeUserName()

MediaWiki\User\ActorStore::normalizeUserName ( string $name )

Returns a canonical form of user name suitable for storage.
