Previously, groups with GROUP_VISIBILITY_NONE could be selected for an
availability condition, but as the group API did not return a user's own
groups with this visibility, the condition's is_available check always
failed.
This change uses the new $includehidden parameter to get all of a user's
groups from groups_get_user_groups when evaluating the condition, so
these groups work as expected. Due to the enforced hiding of conditions
containing these groups, they will never be seen by the user.
The availability condition get_description method is called while
gathering data for the modinfo object. As such it is not safe to
call other functions which might rely on modinfo, such as format_string
(if using filters which access modinfo).
This change provides a mechanism to call format_string later, and also
a general callback to do other stuff later as well if needed. It uses
the same approach already taken to make activity names work correctly
in the availability_condition class.
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.
Previously there was no way in PHP to create the JSON values used for
availability, except by manually hard-coding them (the main code to
do this normally is in JavaScript).
This makes unit tests hard to read, so I have implemented static
functions tree::get_root_json and tree::get_nested_json which allow
for easier-to-read unit tests.
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.
