Current test works ok every day of the year but the day of
DST begin changes (last Sunday of March currently).
That day, 01:00 Europe/London simply doesn't exist, because
the time is moved forward by 60 minutes.
Hence the expectation for the next cron execution is not 1 "normal"
day (24h) but 1 less hour.
Note this only happens for the current test on DST begins, the
opposite change (DST ends), happening the last Sunday of October
is not affected, because, at all effects, 01:00 is a perfectly normal
and existing hour.
The machinery to fix orphaned calendar events that were broken by MDL-67494.
The solution consists of:
1) Upgrade step that checks if this site has executed the problematic upgrade steps and
if positive, it will schedule a new run for calendar_fix_orphaned_events adhoc task.
2) Adhoc task that will self-spawn calling the recovery machinery, running until
all the orphaned calendar events are fixed. It also sets the maximum runtime of
60 seconds. It is also possible to override that number by specifing the desired
number setting the ->calendareventsmaxseconds in your config.php
3) CLI script that will look for all the calendar events which userids
where broken by a wrong upgrade step, affecting to Moodle 3.9.5
and up.
It performs checks to both:
a) Detect if the site was affected (ran the wrong upgrade step).
b) Look for orphaned calendar events, categorising them as:
- standard: site / category / course / group / user events
- subscription: events created via subscriptions.
- action: normal action events, created to show common important dates.
- override: user and group override events, particular, that some activities support.
- custom: other events, not being any of the above, common or particular.
By specifying it (--fix) try to recover as many broken events (missing userid) as
possible. Standard, subscription, action, override events in core are fully supported but
override or custom events should be fixed by each plugin as far as there isn't any standard
API (plugin-wise) to launch a rebuild of the calendar events.
4) Unit tests and helper functions to generate calendar events. We have decided to
keep the tests simple, testing only true and false and not using data generators because
the code is purely to recover the calendar events and won't turn into an API or something
and also due to the urgency of this issue.
The helpers have been created in calendar/tests/helpers.php since there are no data generators
for calendar.
Before this change a teacher would be able to see users listed if:
* They have an active enrolment and can submit
* They have an an inactive enrolment for a role that can submit
After this change they will additonally be able to see users listed:
* That have an active enrolment and have submitted
* That have an inactive enrolment and have submitted
This means that if an assignment has it's context frozen all users
that have made some form of submission will still be listed.
It will also apply if the submission capability is removed from a
user.
If a user's enrolment is deleted they will not be listed.
The submission and grading counts have also been updated so
they will reflect the new rules.
Before this change if a student visited an assignment that is
frozen they would only see the title and description even if
they had made a submission to it.
After the change they will be able to see the status of their
submission and any feedback and grades they have recived.
It will also make the Moodle app recognise that submission
should not happen because the assignment is frozen.
Tests based on ones created by Andrew Nicols
In PHP8.0 using `ksort` was producing incorrect results by sorting
keys differing only in case in the wrong order. This change makes
sorting consistent between PHP versions.

Some recent tests do set a date time element
to ##now## or tomorrow and, immediately after that
the look if, effectively, ##now## and #tomorrow#
have been set (with minutes resolution).
Problem is that, between the field is set and the field
is verified, it can happen that the time advances to
next minute (from H:M:59 to H:M+1:00) and then the
assertion fails.
To avoid this, we could have lowered the resolution to be
hours... but that doesn't solve the problem just makes it
to happen less often.
So, instead of that... we are setting the 2 now and tomorrow
cases to be "today noon" and "tomorrow noon" (12:00:00) so
we ensure they won't be ever in the risk of jumping of minute.
Even if a prediction is hidden from the report once is flagged,
it can be flagged several times if the user visits detailed view via URL.
We remove the checkbox to select a prediction and flag it
once it has already been flagged.
