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

  $id = null 
)

◆ getGlobalSession()

static MediaWiki\Session\SessionManager::getGlobalSession ( )
static

Get the "global" session.

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 454 of file SessionManager.php.

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

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$id
bool$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 199 of file SessionManager.php.

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

◆ 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 $this->getEmptySession().
Parameters
WebRequest$requestAny existing associated session will be reset to the session corresponding to the data in the request itself.
Returns
Session
Exceptions

\OverflowException 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::getSessionFromInfo ( SessionInfo  $info,
WebRequest  $request

$outputPage->addVaryHeader( $header, $options );
