There were existing places each doing its own checks similar to the ones
covered by the newly added core_user::awaiting_action() method. This
patch replaces those custom checks with this new API call.
This class would belong more appropriately within the 'user' API
(core_user) instead of within the 'core' API, since it is
directly related to user data.
Since the class has only just been added to Moodle, now is a good
time to move it.
In all cases changes have been kept to a minimum while not making
the code completely horrible. For example, there are many instances
where it would probably be better to rewrite a query entirely, but
I have not done that (in order to reduce the risk of changes).
Added an admin setting to show/hide the emoji picker in messaging
because some versions of MySQL don't have full unicode support so
emojis won't save in the dabase.
If we detect that the site is running an unsupported version of MySQL
then the setting can not be enabled. Instead the admin will see a
message explaining that they will need to upgrade their database
before they can enable the emoji picker.
It is possible that before this patch the user blocked a
teacher from messaging them, even though this would have
no effect. It is also possible for a user to block a user,
then that user gets 'promoted' to a teacher role and the
block becoming ineffective. In these cases we dont show the
user's status as blocked.
If blocking will have no effect (ie. you are attempting to block
the admin) the 'Block' button will not be shown and instead a
message will be shown explaining why you can not block the user.
We previously had this page when contact requests were first introduced
and unfortunately we created a bunch of notifications that reference
this URL directly which now won't work because the page has been removed.
I've added it back but set it to redirect to the message/index.php page
and load the contact requests page there.
Two modes of visibility checking are supported, depending on the value
of the 'messagingallusers' site setting (site-wide messaging):
- If site-wide messaging is enabled, a user may only be returned in
search results if the searching user can view their profile somewhere
(either the site profile or any course profile).
- If site-wide messaging is disabled, a user may only be returned in
search results if the searching user shares a course with them and can
view their course profile in the shared course.
Individual conversations with a soft-deleted user (including messages)
are now displayed in the conversation listing. This brings the behaviour
of individual conversations in line with group conversations, in that
the active user can still view messages.
