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.
