List of changes: * New OOP API using PHP namespace \core\session\. * All handlers now update the sessions table consistently. * Experimental DB session support in Oracle. * Full support for session file handler (filesystem locking required). * New option for alternative session directory. * Official memcached session handler support. * Workaround for memcached version with non-functional gc. * Improved security - forced session id regeneration. * Improved compatibility with recent PHP releases. * Fixed borked CSS during install in debug mode. * Switched to file based sessions in new installs. * DB session setting disappears if DB does not support sessions. * DB session setting disappears if session handler specified in config.php. * Fast purging of sessions used in request only. * No legacy distinction - file, database and memcached support the same functionality. * Session handler name included in performance info. * Fixed user_loggedin and user_loggedout event triggering. * Other minor bugfixing and improvements. * Fixed database session segfault if MUC disposed before $DB. Limitations: * Session access time is now updated right after session start. * Support for $CFG->sessionlockloggedinonly was removed. * First request does not update userid in sessions table. * The timeouts may break badly if server hosting forces PHP.ini session settings. * The session GC is a lot slower, we do not rely on external session timeouts. * There cannot be any hooks triggered at the session write time. * File and memcached handlers do not support session lock acquire timeouts. * Some low level PHP session functions can not be used directly in Moodle code.

* Web cron
|
|
*
|
|
* This script looks through all the module directories for cron.php files
|
|
* and runs them. These files can contain cleanup functions, email functions
|
|
* or anything that needs to be run on a regular basis.
|
|
*
|
|
* This file is best run from cron on the host system (ie outside PHP).
|
|
* It is strongly recommended to add password protection via admin settings.
|
|
*
|
|
* eg wget -q -O /dev/null 'http: *moodle.somewhere.edu/admin/cron.php?password=SeCreT666'
|
|
*
|
|
* It is also possible to use CLI script admin/cli/cron.php instead,
|
|
* you can not call this script from command line any more.
