Includes:
* each plugin has own thirdpartylibs.xml file
* added missing libraries
* fixed existing library infos
* new Site administration / Development / Third party libraries page
Too many functions, too different parameters, unnecessary DB queries.
All repositories developed for Moodle 2.3-2.5 will continue to work.
Also get rid of DB field files_reference.lifetime, it is not used by
anybody except repository itself.
Fields files.referencelastsync and files.referencelifetime just waste the space and actually duplicate the fields
files_reference.lifetime and files_reference.lastsync
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.
Fixes display issues with the filepicker dialogs that were
converted to M.core.dialogue.
Note: These dialogue use table based layouts and the table width is not
counted in the form that it sits in. I have changed the dialogues to have
a wider width but for really small screens this causes horizontal scrolling.
The only solution for that is to rewrite all the filepicker/filemanager dialogs
to use css for layout.
Items addressed
* Get rid of custom attribute srcNode
* Change extraClasses to a config only parameter.
* Change attribute fullscreen to a method.
* Restore the original window overflow value.
* Use setStyles instead of setStyle for performance.
* Tinymce end the zindex wars
* Prevent fullscreen dialogs in an iframe (tinymce managefiles plugin).
* tinymce: Cross browser fix for zindex on popups
* Use CSS for overflow changes (easier to keep track of the previous state).
* Fix Coding style for css changes
This change adds support to M.core.dialogue for showing fullscreen
dialogs on small screen sizes. There are 2 new configuration values that
can be set to control this when creating a dialog (responsive and responsiveWidth).
Setting responsive to false will disable this functionality completely (old behaviour).
Setting responsiveWidth controls the screen width that the dialog will switch to
fullscreen mode. Try not to think of the device that will be accessing the dialog,
but the width at which the content of the dialog needs to be displayed differently.
The activity chooser and the filepicker are the two dialogs that have been converted
in this patch. The filepicker first had to be converted to use M.core.dialog and not
Y.Panel.
