This patch includes:
* version column removed from modules table, now using standard config, this allows decimal version for modules
* version column removed from block table, now using standard config, this allows decimal version for blocks
* module version.php can safely use $plugins instead of module
* new plugin_manager bulk caching, this should help with MUC performance when logged in as admin
* all missing plugins are now in plugin overview (previously only blocks and modules)
* simplified code and improved coding style
* reworked plugin_manager unit tests - now using real plugins instead of mocks
* unit tests now fail if any plugin does not contain proper version.php file
* allow uninstall of deleted filters
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.
generate_email_supportuser was not creating user which can
be used by messaging system. core_user::get_support_user()
should be used to get support_user record.
For example, a user may create a date/time profile field and set the 'Start year'
field to '2012'. Another user, using the Hijri calendar, may edit the name of
this field. They visit the settings page and in this case the date '1/1/2012'
is converted to '7/2/1433' in Hijri. So, the year '1433' is then displayed.
The user then changes the name of this field and saves the form. This is where
the issue occurs, as the date '1/1/1433' is converted into Gregorian, which
converts to the year '26/09/2011', so the year '2011' is saved in the DB, not
'2012'.
1) Moved the calendar types location to a sub-folder in the calendar directory.
2) Removed/moved language strings.
3) Removed calendar types that should be downloaded as plugins.
4) Removed a Non-English language pack for the Gregorian calendar type that
should be downloaded separately.
5) Removed custom files responsible for checking for updates and uninstalling
calendar types, which should be done by core.
6) Removed JS from the calendar_month block as there is no non-JS alternative
provided and the JS written does not make use of the YUI library to ensure
multiple browser support.
7) Removed code from the base class responsible for creating timestamps that
are saved in the DB.
8) Added PHPDocs.
Note: In the original patch we are editing core functions responsible for saving
time in the database in the calendar base class. This is very dangerous, we do
not want to touch these functions as it could cause a complete fubar of the
database. There are places we are forcing the use of the gregorian calendar as
we are passing dates generated by the PHP date function, where as sometimes
we pass dates from usergetdate (which was being overwritten to return the
date specific to the calendar). We can not expect third party modules to
change the calendar type depending on the format they pass to these functions.
