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.
Solution is as follows:
* Allow unsupported subplugins to convert from Moodle1 to Moodle2
* On Moodle2 restore hide unsupported subplugins
* Graceful error message in assignment of unsupported subplugins
Non-standard means php.ini was set to something not in the default list (like 7MB),
then the config was saved to that specific value, and now the value in php.ini has been changed
again so 7MB does not appear in the list.
This change removes the "0 bytes" option from the get_max_upload_sizes list
and replaces it with "Course limit (X)" or "Site limit (X)" (whichever is smaller).
This means we can remove all custom handling in the modules that were removing and
adding these options. It only affects pages that pass valid options for sitelimit and
courselimit - so admin pages will work correctly.
It also orders the list so the course/site limit options will be first
(as it will be the largest).
AMOS START
REM [courseuploadlimit, core] has been parameterized to get [uploadlimitwithsize, core]
AMOS END
