This fixes a regression caused by MDL-74752. If you regraded
a subsequent quiz attempt in a quiz using the 'Each attempt
builds on last' option, then the student's response could get lost.
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.
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 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.
This got lost in the 4.0 question bank work.
We are trying to phase out qtype_random, that is where the old
code and lang strings for describing random questions is, so
OK to add back a call to it. When we get better qbank filtering
we can replace this again.
Note, the asserts in the Behat were copied from my 3.11, checkout,
to really verify we are restoring the previous behaviour.
This fixes lots of stuff like outdated or incomplete PHPdoc comments
or test heler functions where the arguments don't have their types
declared.
A few more significant fixes, like places were a silly method
was used to get a context which was readily available.
Various tests have been added to cover the points fixed in the previous
commit, using a localised decimal separator (#). Using the same
numbering, here there are the details:
A. grade/report/singleview/tests/behat/singleview.feature
grade/tests/behat/grade_category_validation.feature
B. grade/tests/behat/grade_override_letter.feature
C. (done within various scenarios)
D. grade/report/singleview/tests/behat/singleview.feature
E. admin/tool/behat/tests/behat_form_text_test.php
F. grade/tests/behat/grade_to_pass.feature
mod/lesson/tests/behat/lesson_informations_at_end.feature
G. quiz/tests/behat/preview.feature
H. mod/quiz/tests/behat/info_page.feature
I. question/type/ddimageortext/tests/behat/edit.feature
It has been detected, thanks to php80 specially, that there are
various places in core where support for localised floats is
missing. Before php80, some locale-dependent conversions were
performed by PHP, allowing things to work. But with php80 all
those comparisons are now locale-independent. See:
https://wiki.php.net/rfc/locale_independent_float_to_string
That implies that we now need to, always, unformat floats to
be internally the correct (decimal point as separator) in
order to compare it.
While this was visited in the php80 epic (MDL-70745), nothing
was found, all automated tests were passing ok. Problem is that
we run behat tests with en-AU laguage that has the decimal point
separator.
So, in this issue we are fixing all the problems detected by
running those Behat tests using localised (comma) decimal
separator.
Note that there may be other places still causing problems, but
it's really hard to find them programmatically, so we'll have to
wait for real use reports / issues and go fixing them while they
happen.
Back to this commit, this is the list of changes performed (note that
in the next commit, we'll be adding scenarios explicitly using
a localised decimal separator to ensure that they work ok).
A. Changes to various grade forms to ensure that, on their validation
floats are unformatted properly. Also, changed the corresponding
form element from current text/PARAM_RAW to proper float ones that
take care of the conversion in a number of places (but when disabled,
that's the reason we still have to unformat in validation.
This includes the following forms:
- edit_category_form
- edit_item_form
(this is the original problem reported that cause all the research
to be performed against full behat runs)
B. Changes to edit_letter_form, so it uses a proper PARAM_LOCALISEDFLOAT
(note this is the type of change that surely should be used for all
the rest of /grade/edit/tree form, including those in the previous
point).
C. Changes to the grade_item behat generator, so it's able to work with
localised floats, un-formatting them when needed.
At lib/behat/classes/behat_core_generator.php
D. Fix problem passing localised floats to scales, not displaying
properly. At grade/report/singleview/classes/local/ui/finalgrade.php
E. Change the behat text matcher in order to allow comparison of
localised floats when they are the current ones. Before this change
the matches was using soft/lazy comparison, so '50' and '50.0000'
match. Now, when the comma (for example) is used (and only then),
'50' and '50,000' will also match. This comparison is in use in a
bunch of tests and makes sense to make it localisation-aware.
At grade/report/singleview/classes/local/ui/finalgrade.php
F. Fix a couple of number_format() uses in lesson, because they are
not localised-aware. Switched to format_float(). At mod/lesson/locallib.php
G. Change the quiz_contains_the_following_questions() step to accept
localised maxmark expectations. At mod/quiz/tests/behat/behat_mod_quiz.php
H. Change the quiz generator so it accepts localised gradepass.
At mod/quiz/tests/generator/lib.php
I. Change the edit question form to show proper localised penalties,
previously it was always showing point-decimal ones. Of course,
leaving the values of the select element unmodified (internal floats).
Related, also change a couple of tests to, instead of try to match the
value (always internal floats), match the description (now localised),
so we can test them with different separators. At:
- question/type/ddimageortext/tests/behat/backup_and_restore.feature
- question/type/ddmarker/tests/behat/backup_and_restore.feature
- question/type/edit_question_form.php
To all the walkthrough, questiontype, question, upgradelibnewqe,
behaviourtype_test and edit_form 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.
Special mention to:
- When belonging to other component and being valid api:
- form related tests have been moved to tests/form subdir.
When questions are deleted, we now check if the parent is in use before deletion.
Prior to this, it would be possible for multianswer questions to reference
questions that have been deleted. This results in fatal errors when the quiz
is viewed.
This patch uses a dummy 'subquestion_replacement' to handle this case and
display some information to the end user about what has happened so that
they may take action to repair the corrupted question.
As a result of the bug described above, the sequence column of
mdl_question_multianswer can contiain references to questions that no
longer exist, and these IDs can make their way in to backups.
When this happens, the backups cannot be restored. To avoid this,
this patch skips trying to restore those questions that reference
question IDs that no longer exist (as there is no way to recover them).
