Detailed Description

This serves as the entry point to the MediaWiki session handling system.

Most methods here are for internal use by session handling code. Other callers should only use getGlobalSession and the methods of SessionManagerInterface; the rest of the functionality is exposed via MediaWiki\Session\Session methods.

To provide custom session handling, implement a MediaWiki\Session\SessionProvider.

Since: 1.27

◆ getGlobalSession()

static MediaWiki\Session\SessionManager::getGlobalSession ( )

If PHP's session_id() has been set, returns that session.

Otherwise returns the session for RequestContext::getMain()->getRequest().

Returns: Session

◆ getProvider()

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 456 of file SessionManager.php.

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

◆ getProviders()

MediaWiki\Session\SessionManager::getProviders ( )

protected

Get the available SessionProviders.

Returns: SessionProvider[]

◆ getSessionById()

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

Fetch a session by ID.

Parameters

string	$id
bool	$create	If 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	$request	Corresponding request. Any existing session associated with this WebRequest object will be overwritten.

Returns: Session|null

Implements MediaWiki\Session\SessionManagerInterface.

Definition at line 224 of file SessionManager.php.

References MediaWiki\Session\SessionManager\getEmptySessionInternal(), MediaWiki\Session\SessionManager\getSessionFromInfo(), MediaWiki\Session\SessionManager\loadSessionInfoFromStore(), and MediaWiki\Session\SessionInfo\MIN_PRIORITY.

◆ getSessionForRequest()

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

Fetch the session for a request (or a new empty session if none is attached to it)

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 $request Any existing associated session will be reset to the session corresponding to the data in the request itself.

Returns: Session

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

◆ getVaryHeaders()

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 );
}

Note that the $options argument to OutputPage::addVaryHeader() has been deprecated and should always be null.

Returns: array

◆ invalidateSessionsForUser()

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

Implements MediaWiki\Session\SessionManagerInterface.

Definition at line 336 of file SessionManager.php.

References MediaWiki\Session\SessionManager\getProviders(), User\saveSettings(), and User\setToken().

◆ isUserSessionPrevented()

Definition at line 418 of file SessionManager.php.

◆ loadSessionInfoFromStore()

MediaWiki\Session\SessionManager::loadSessionInfoFromStore	(	SessionInfo &	$info,
		WebRequest	$request
	)

private

Load and verify the session info against the store.

Parameters

SessionInfo	&$info	Will likely be replaced with an updated SessionInfo instance
WebRequest	$request

Returns: bool Whether the session info matches the stored data (if any)

Definition at line 550 of file SessionManager.php.

Referenced by MediaWiki\Session\SessionManager\getSessionById(), and MediaWiki\Session\SessionManager\getSessionInfoForRequest().

◆ logPotentialSessionLeakage()

MediaWiki\Session\SessionManager::logPotentialSessionLeakage ( Session $session = null )

If the same session is suddenly used from a different IP, that's potentially due to a session leak, so log it.

In the vast majority of cases it is a false positive due to a user switching connections, but we are interested in an audit track where we can look up a specific username, so a noisy log is fine. Also log changes to the mwuser cookie, an analytics cookie set by mediawiki.user.js which should be a little less noisy.

Access:\n private For use in Setup.php only

Parameters

Session | null $session For testing only

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