This combines the following changes:
* Event for group member added
* Event for group member removed
* Event for group created
* Event for grouping created
* Event for group updated
* Event for grouping updated
* Event for group deleted
* Event for grouping deleted
* Adding tests for deleting functions
* Bulk remove of members uses low-level API
The reason for this is that a bulk event has no value from a logging
perspective as it is not granular. So now, the API is a bit slower,
but the information the events contain makes sense, beside this is
not (and should not be) used very often.
The reason why the events_trigger_legacy() is kept is because we
cannot create a new event for this, as we don't encourage developers
to created bulk events, for the reasons mentioned above.
I removed the call that gets the user record from the function
groups_remove_member() as it was not required and only appeared
to check if the user existed. It appears to be safe not to do
this check as nothing would fail down the line.
* Bulk unassign of groupings uses low-level API
As the previous commit, we keep the legacy event for now as it would
be wrong to create a new event to replace it.
Also, the code has been changed to call the low-level API to unassign
groups from groupins, even though at the moment there are no
events for that function.
* Bulk deletion of groups uses low-level API
Again, we keep the legacy event because replacing it would force
us to create a new event that does not make sense. See MDL-41312.
* Bulk deleting of groupings uses low-level API
* Asserting legacy event name in unit tests
* Minor SQL query and code improvements
List of fixes:
* Add a simulated drag start event to fix problems with block drag and drop that
were expecting it.
* Add an access-hidden title for the General section in a course format. This
is used to provide the text for the drop region (better than the first activity in the section)
* Changed the text in the list to 'Move to "General"' instead of 'Move after General'. This
makes more sense for activities when you have a list of activities and sections together.
* Added more PHP Documentation
* Localised strings for get_name()
* get_legacy_eventname() is now static
* get_legacy_eventdata() is now protected
* Testing legacy event data
* Added missing defined('MOODLE_INTERNAL') checks
* Added missing call to add_record_snapshot()
Includes:
* no more hacky reloads, everything is written only once and kept until cache reset
* lang menu list is now cached in MUC
* both string and lang menu caches are compatible with local caches on cluster nodes
* config-dist.php cleanup
