This changes the cache purge code to select IDs for deletion
first, rather than using a subquery in a DELETE, since this
risks causing a deadlock in MySQL.
Moves the data-filtercondition property to an element that always
exists regardless of whether the selected category from the filter
has questions or not. This will effectively solve the exception
that is being thrown due to the non-existing element and also
enable creation of random questions in a category that does not
have any questions yet. Also, the data-filtercondition attribute
is no longer used when creating a random question in a new category
as this value is not relevant in this case. Instead, a default
filter condition is generated in the webservice for the random
question based on the newly created category.
Chrome ignores min-width on table headers with table-layout:fixed,
meaning that question bank headers could be resized so that the controls
were overlapping, and could be too narrow by default.
This removes min-width: min-content in the headers and instead uses
Javascript to calculate a constrain a min width based on the content of
the headers.
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.
This modifies the question_data fragment used by the filter code to make its
parameters closer to the URL parameters of the question/edit.php page. This
Allows us to progressively enhance the add, remove and reset actions on the
question bank page, using this same fragment to reload the question table after
each change. This re-uses the same actions.js module used for enhancing these
actions on the qbank_columnsortorder admin screen.
This also resolves MDL-78829.
Some question bank plugins use a separate class for each plugin they
define. However, qbank_customfields (and potentially others in the
future) uses a single class to define multiple fields. Using the class
name as an ID for the column doesn't give us a way of reliable
instantiating an object for the column. Previously, qbank_customfields
appended the field name as though it was a namespaced class, but this
had to be manually constructed and deconstructed by detecting this
particular column class.
This change introduces a standard way of constructing a unique ID for
each question bank column, in the form
pluginname\columnclass-columnname. This ensures that the ID will be
unique for each column, and the ID can be used to instatiate the
column's object.
This changes the root element used by the fragment when
applying filters, so that the whole of display_question_list()
is reloaded.
This ensures that the returnurl will be updated correctly on the
question actions and bulk actions without manipulating then
further in Javascript.
If a quiz had a long job to calculate statstics running, this would
cause pages that may also attempt a recalculation (the statistics report
page or question bank) to load very slowly, and possibly result in a
database deadlock.
This change will firstly prevent the question bank page performing
analysis calculations at all, since these are not required for this
page, which will speed up loading and prevent deadlocks on this page.
Secondly, this adds a lock to the recalcuation process so that it cannot
run twice concurrently. This will present the user with a message to
indicate that it is waiting for a running calculation until it is
complete, and eventually it will timeout with a message and debugging.
We were experiencing problems caused by old stats analysis in our
database, computed when there was a bug, causing fatal errors
when they were displayed. Therefore, this code needs to be robust to that.
Since PHP 8.2, all properties on a class must be defined as the PHP
Dynamic Property feature has been deprecated.
This commit goes one step further and switches this class to using
constructor property promotion. This language feature has been available
since PHP 8.0 and allows for simplified creation of class properties
which are initially defined in the constructor.
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.
This commit will implement question bank actions as a feature.
Previously, it used to implement columns and actions together in one
feature.
With this change it will have actions a different feature which will
allow
developers to implement actions in an easier way.
The existing "action column" API will be deprecated in a separate
commit.

Previously, a set of calculated quiz statistics would only 'last' for
15 minutes. Then they would be considered invalid and not used.
Now, computed statistics are kept indefinitely. Instead, when a new
batch of values are computed for a particular set of settings, older numbers
for the same settings are deleted first. Therefore,
question_stats_cleanup_task is no more.
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.
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.

PHP before version 8.1 automatically converted to int if the function
parameter (or array key) is expected to be int. PHP 8.1 shows notice in
this case
