It should always be the case that a question category and its parent
category belong to the same context. However, over the years, we have
observed that this becomes violated by some data in some Moodle sites.
(The suspicion is that this is a backup/restor bug of some sort which
has never been tracked down.)
Since this happens, we should make the code robust to it, which is what
this change does. It ensure that when loading child categories, we only
consider ones in the same context.
The Binary datafilter was returning a single value where all parts of
the API expect an array of values. This was working in most places by
fluke as this value was a single-character string, so doing $value[0]
returned the value. However, it was not working when deciding which
option to mark as selected when re-displaying the filter.
This change makes the filter return an array containing a single integer
value to match the rest of the API, then internally selects that single
value for comparison when deciding if an option should be selected.
Previously, quiz statistics processing happened on a scheduled task.
This task looked for all quizzes with completed attempts, then
determined if those quizzes had a statistics calculation that's newer
than the most recent attempt, then ran the statistics calculation if
needed. It was hard coded to stop processing after 1 hour.
The queries involved in determining which quizzes needed processing
weren't terribly efficient, and combined with the 1 hour limit this made
the statistics unusable on large sites, where they are the most useful.
This converts the scheduled task to an ad-hoc task, and uses an event
observer for mod_quiz\event\attempt_submitted to queue a task when
it is needed. This removes the need for a query to work out what needs
processing, and allows the task processing to be scaled up as needed.
This replaces the "Show question text in the question list?" filter, which was
never really a filter, with a new widget displayed alongside other question bank
controls like "Create a new question" and "Reset columns".
It also refactors the logic of displaying the question text field or not, so that
it is all handled within the qbank_viewquestiontext plugin rather than relying on
code in the view.
It turns out that there are plugins which don't (currently)
clean up their question attempts when a context is deleted.
Therefore, we need to make Moodle core robust to that.
Previously, when a user viewed the question bank, if the quiz statistics
had not already been calculated, we would try to compute them there an then.
This could be very, very slow, leading to session lock problems.
Now, we never try to compute the statistics on the fly. Instead, we rely
on the existing \quiz_statistics\task\recalculate scheduled task to do it.
There is a new method on the column class, for the column to declare any
statistics it requires. The question then efficiently loads all those
statistics in one go, and makes them available as the columns are
rendererd, or do any subsequent processing.
* The object returned by update_question is alwasy a new clone
and the $question passed in will not be modified.
* The returned object has the fields like questionbankentryid and
the ones related to versionning, so it is more like the data
returned by question_bank::load_question_data.
This adds "core_question > updated question" as an entity for `the
following "X" exist` and calls the existing update_question() generator
which will create a new question version with the supplied data.
In PHP 8.2 and later, setting a value to an undeclared class property is
deprecated and emits a deprecation notice.
So we need to add missing class properties that still need to be declared.

By using that assertion the arrays will be sorted before comparison
preventing any Oracle sorting related failures.

Applied the following changes to various testcase classes:
- Namespaced with component[\level2-API]
- Moved to level2-API subdirectory when required.
- Fixed incorrect use statements with leading backslash.
- Remove file phpdoc block
- Remove MOODLE_INTERNAL if not needed.
- Changed code to point to global scope when needed.
- Fix some relative paths and comments here and there.
- All them passing individually.
- Complete runs passing too.
This is the expected naming for a Behat file for a core component.
Note, there are no acutal references to the deprecated class name
in core, but there might be in plugins, so we added a
backwards compatibility class with the old name. Thanks to
Andrew Lyons for hints about how to do that.
