Detailed Description

This is the actual workhorse for Session.

Most code does not need to use this class, you want \MediaWiki\Session\Session. The exceptions are SessionProviders and SessionMetadata hook functions, which get an instance of this class rather than Session.

The reasons for this split are:

A session can be attached to multiple requests, but we want the Session object to have some features that correspond to just one of those requests.
We want reasonable garbage collection behavior, but we also want the SessionManager to hold a reference to every active session so it can be saved when the request ends.

Since: 1.27
