Member Function Documentation

static MediaWiki\Session\SessionManager::autoCreateUser ( User  $user)
static

Auto-create the given user, if necessary.

Access:
private Don't call this yourself. Let Setup.php do it for you at the right time.
Deprecated:
since 1.27, use MediaWiki\Auth\AuthManager::autoCreateUser instead
Parameters
User$userUser to auto-create
Returns
bool Success

Definition at line 379 of file SessionManager.php.

References wfDeprecated().

MediaWiki\Session\SessionManager::changeBackendId ( SessionBackend  $backend)

Change a SessionBackend's ID.

Access:
private For use from \MediaWiki\Session\SessionBackend only
Parameters
SessionBackend$backend

Definition at line 903 of file SessionManager.php.

References MediaWiki\Session\SessionManager\generateSessionId(), MediaWiki\Session\SessionBackend\getSessionId(), and string.

MediaWiki\Session\SessionManager::deregisterSessionBackend ( SessionBackend  $backend)

Deregister a SessionBackend.

Access:
private For use from \MediaWiki\Session\SessionBackend only
Parameters
SessionBackend$backend

Definition at line 885 of file SessionManager.php.

References MediaWiki\Session\SessionBackend\getId(), and MediaWiki\Session\SessionBackend\getSessionId().

MediaWiki\Session\SessionManager::generateSessionId ( )

Generate a new random session ID.

Returns
string

Definition at line 925 of file SessionManager.php.

References $key, MWCryptRand\generateHex(), store, wfBaseConvert(), and wfMemcKey().

MediaWiki\Session\SessionManager::getEmptySession ( WebRequest  $request = null)

Fetch a new, empty session.

The first provider configured that is able to provide an empty session will be used.

Parameters
WebRequest | null$requestCorresponding request. Any existing session associated with this WebRequest object will be overwritten.
Returns
Session

Implements MediaWiki\Session\SessionManagerInterface.

Definition at line 234 of file SessionManager.php.

References $request, and MediaWiki\Session\SessionManager\getEmptySessionInternal().

MediaWiki\Session\SessionManager::getEmptySessionInternal ( WebRequest  $request = null,
  $id = null 
)
private
MediaWiki\Session\SessionManager::getProvider (   $name)

Get a session provider by name.

Generally, this will only be used by internal implementation of some special session-providing mechanism. General purpose code, if it needs to access a SessionProvider at all, will use Session::getProvider().

Parameters
string$name
Returns
SessionProvider|null

Definition at line 447 of file SessionManager.php.

References $name, and MediaWiki\Session\SessionManager\getProviders().

Referenced by MediaWiki\Session\SessionManager\loadSessionInfoFromStore().

MediaWiki\Session\SessionManager::getSessionById (   $id,
  $create = false,
WebRequest  $request = null 
)

Fetch a session by ID.

Parameters
string$id
bool$createIf no session exists for $id, try to create a new one. May still return null if a session for $id exists but cannot be loaded.
WebRequest | null$requestCorresponding request. Any existing session associated with this WebRequest object will be overwritten.
Returns
Session|null

Implements MediaWiki\Session\SessionManagerInterface.

Definition at line 192 of file SessionManager.php.

References $key, $request, MediaWiki\Session\SessionManager\getEmptySessionInternal(), MediaWiki\Session\SessionManager\getSessionFromInfo(), MediaWiki\Session\SessionManager\loadSessionInfoFromStore(), MediaWiki\Session\SessionInfo\MIN_PRIORITY, store, and wfMemcKey().

MediaWiki\Session\SessionManager::getSessionForRequest ( WebRequest  $request)

Fetch the session for a request.

Note
You probably want to use $request->getSession() instead. It's more efficient and doesn't break FauxRequests or sessions that were changed by $this->getSessionById() or $this->getEmptySession().
Parameters
WebRequest$requestAny existing associated session will be reset to the session corresponding to the data in the request itself.
Returns
Session
Exceptions
if there are multiple sessions tied for top priority in the request. Exception has a property "sessionInfos" holding the SessionInfo objects for the sessions involved.

MediaWiki\Session\SessionManager::getVaryCookies ( )

Return the list of cookies that need varying on.

Returns
string[]

Implements MediaWiki\Session\SessionManagerInterface.

Definition at line 341 of file SessionManager.php.

References MediaWiki\Session\SessionManager\$varyCookies, as, MediaWiki\Session\SessionManager\getProviders(), and MW_NO_SESSION.

MediaWiki\Session\SessionManager::getVaryHeaders ( )

Return the HTTP headers that need varying on.

The return value is such that someone could theoretically do this:

foreach ( $provider->getVaryHeaders() as $header => $options ) {
$outputPage->addVaryHeader( $header, $options );
}
Returns
array

Implements MediaWiki\Session\SessionManagerInterface.

MediaWiki\Session\SessionManager::invalidateSessionsForUser ( User  $user)

Invalidate sessions for a user.

After calling this, existing sessions should be invalid. For mutable session providers, this generally means the user has to log in again; for immutable providers, it generally means the loss of session data.

Parameters
User$user

MediaWiki\Session\SessionManager::isUserSessionPrevented (   $username)

Test if a user is prevented.

Access:
private For use from SessionBackend only
Parameters
string$username
Returns
bool

Definition at line 412 of file SessionManager.php.

References $username.

MediaWiki\Session\SessionManager::preventSessionsForUser (   $username)

Prevent future sessions for the user.

The intention is that the named account will never again be usable for normal login (i.e. there is no way to undo the prevention of access).

Access:
private For use from \User::newSystemUser only
Parameters
string$username
