Recently, PHPUnit (all versions) did some changes about how the
comparators worked and this has caused some float comparisons
to stop working.
We need to move them to assertEqualsWithDelta(), allowing a small
tolerance to workaround the floats comparison problem.
0.00001 has been decided. And applied to all the similar assertions
within the unittest function, so if more cases are added to them
better be copied with the agreed tolerance.
This issue greatly improves the performance of displaying statistics in
the question bank.
1. The required quiz statistics are now pre-computed by a scheduled task.
2. Cached statistics in the database are now never cleaned up, so the
pre-computed stats are always available.
3. The way the cached statistics are loaded for each question
that is being displayed is now a bit more efficient.
4. Related to that, there is a new callback which activities can implement,
if they want their question statistics to be included in the ones shown
in the question bank.
Note, there is still further improvement possible to load the statistics
for all questions being displayed in bulk. However, that must wait for a
future issue, MDL-75576. The other improvements in this issue are
significant and we did not want to delay releasing them.

The uniqueidentifier argument is only needed by the version selector and
can be set within the output fragment function using it. There's no need
for it to be a parameter when calling the output fragment function.

This just deletes all the upgrade steps previous to 3.9.0. Some
small adjustments, like tweaking globals can also be applied
when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2020061500 (v3.9.0) as anti-cheating measure.
The next commits will proceed to deprecate / remove functions
that were exclusively (usually belonging to upgradelib) being
used by those, now removed, upgrade steps. This is the list
of code to remove and document in upgrade.txt files:
- upgrade_analytics_fix_contextids_defaults()
- upgrade_convert_hub_config_site_param_names()
- upgrade_rename_prediction_actions_useful_incorrectly_flagged()
- \mod_forum\task\refresh_forum_post_counts adhoc task.
And these is the code that has NOT been removed
because it may be needed later (no matter there aren't uses now):
- \core_search\manager::clean_up_non_existing_area(), used by
- \core\task\clean_up_deleted_search_area_task adhoc task
The implements the new regrade-related hooks, and also has
tests for the changes to the core system, now that we have a question
type we can use for them.
This commit implements the necessary core hooks to ensure we only
allow a regrade of a quetion attempt to take place if the new and old
versions of the question are sufficiently similar.
It will be followed by commits to each question type where the
new method needs to be implemented.
Automated tests will be included in the first of those (mulitple choice)
becuse we need a question type that implements the hooks to test
the core changes.
