Removing the table "scheduled" created by the XMLDB by default (it's a
bug in XMLDB, I'm just too lazy now to fix it). Adding new fields to
hold the result of the most recent execution.
On every invocation, the workshop will give its subplugins a chance to
to something useful. For now, we know that the scheduled allocator will
use it, no need to load other plugin types yet (until there will be a
real reason for it).
The idea is to build a plugin that will internally call the random
allocator when the submissions deadline is reached. The teacher is able
to pre-define the configuration for the random allocator.
The random allocator's init() method was split into two logical
parts. The init() now handles data from the form and executes the new
execute() method to do the actual job. The execute() method will be
called by the future scheduled allocator, too.
The patch introduces two new classes for rendering assessments of
example submission - both the training one and the reference one.
Together with the cooking functions for obtaining instances of these
classes.
QuickForms do not distinguish non-checked radio from the checked radio
with the value "0". So we map the database grade value "0" to a value
"-1" when displaying the form and vice versa when saving the form. This
allowed us to have none radios checked by default and force the grader
to actually answer the form themselves, using the 'required' rule.
This patch introduces a new hidden field with the value "-1". The grade
selectors are compared with this values and must be greater than it.
This should fit well for numerical grades with the range 0..x and scale
items with the range 1..x.
New PARAM_COMPONENT, PARAM_AREA and PARAM_PLUGIN + fixing of hopefully all current incorrect parameter types. This should help with diagnosing of incorrectly named 3rd party plugins too.
The Workshop module using the "Number of errors" grading strategy did
not save all items in the grade mapping table. If some assessment form
fields have weight > 1, the number of possible errors is greater that
the number of the assessment form fields. The previous code deleted all
mappings where the number of errors was greater than the number of
fields.
In this patch, the maximum number of possible errors is calculated as a
sum of weights of all fields. Only mappings over this maximum are
deleted now.
For modules that still used the 'old' generic object return from _get_coursemodule_info instead of returning a cached_cm_info object, I changed them to use the new format as part of this. This made a few areas of code regarding onclick links slightly nicer.
