In a pretty rare case of zero variance of received assessments, the "distance"
of the evaluated assessment from the referential ("best") one was not increased
regardless it's actual value. This led to higher grades for assessments in
certain situations (see the tracker for a particular example).
The $sql used in these methods may contain multiple parts glued
together by the UNION operator. Simply appending the ORDER BY statement
to the end of the query does not work in all DBs (failure reported at
Oracle). Following the pattern already applied in MDL-30051, we wrap the
SQL into yet another SELECT statement and perform ordering there.
Credit goes to Sara Cenni for suggesting the fix.
If the user is allowed to see the published submission, she must be also
able to see images in it (both embedded into the text as well as
attached to the submission). See the logic in submission.php as a
reference.
Now we are checking for the need to execute the allocator every time the
main view.php is displayed to any user. Previously this was done by cron
only.
Now we are checking for the need to switch the phase when the main
view.php is displayed to any user (previously this was done via cron
only). To give our subplugins (such as the scheduled allocation method)
a chance to do what they need to do, the workshop_viewed event is
triggered before the phase is actually switched.
The documentation suggested that the modname field should be present on the
$workshop parameter when this is not required. It is not used in any point
in the function and the $workshop variable is never passed to another
function which may use it.
From now on, the evaluator's method get_settings_form() should return a
subclass of workshop_evaluation_settings_form. The evaluation subplugins
are expected to use the define_sub() method to add their own fields into
the base form, although they can override the main define() method, too.
The former interface workshop_evaluation has been refactored into a
superclass with abstract methods which seems to be more robust.
Oh, by the way, I'm in Perth - yay!

Teachers can now choose the actual grading evaluation method to use
during the grading evaluation phase. The workshopeval_best is still used
as the default one (this may be made configurable later, although there
is no big benefit of it).
- file_info class now has new methods get_non_empty_children and count_non_empty_children; added default implementation;
- all core classes extending file_info have their implementation of those methods;
- class repository_local_file used for caching get_children() results is removed;
- class repository_local rewritten to use new methods from file_info;
- added caching of retrieved modules in file_browser::get_file_info_context_module() - this query is slow and executed multiple times on big servers
This commit coverts everything in the codebase to use the new
users_order_by_sql function when sorting lists of users. More details in
the bug.
Note that this does not change places where users are displayed in a
sortable table, and the sort order comes from the table.
