The previous API included a facility to filter a list of users
to include only those who are allowed to access an activity, i.e.
only people who belong to the required groups etc.
This change adds a new API function to return SQL that obtains
this list of users, so that it can be combined with other
queries.
Remove groupmembersonly usage in the core_availability API, and change
the update code (used in backup) so that it considers groupmembersonly
when restoring old backups.
If there is invalid data in the availability condition (note: this
should not happen, but can do in unusual situations, such as
specifying a date after 2038 in 32-bit PHP), this should not
leave the course so broken that users cannot edit the activity and
update it.
Includes all the conditions that were in previous Moodle versions:
* Date
* Grade
* Completion (of another activity)
* User profile field
Also includes conditions that are used to reimplement
groupmembersonly:
* Grouping
* Group
For each condition, the component plus unit tests are included.
PLEASE NOTE: The code to actually check each condition is reused
from previous Moodle versions and has not been modified except to
pass codechecker. This is intentional, to reduce the risk of the
change and maximise the chance that behaviour is preserved. Some
of this code might not be very good and might need updating but
that can happen separately.
