Also deprecated the following functions -
1. message_move_userfrom_unread2read - It is not necessary
for us to mark a message as read on user deletion.
2. message_get_blocked_users - Horrible logic used to
determine if a user is blocked via reference on some
randomly chosen 'isblocked' variable.
3. message_get_contacts - The same as above. This can be
done in a much nicer way.
4. message_mark_message_read - We want two functions to do
this to avoid confusing messages and notifications.
5. message_can_delete_message - This assumed the variable
$message contained the 'useridto' property, which
was present in the old table structure. We do not want
future usages where a query is done on the new table
and is simply passed as this won't contain this property.
6. message_delete_message - Same as above.
dirname() is a slow function compared with __DIR__ and using
'/../'. Moodle has a large number of legacy files that are included
each time a page loads and is not able to use an autoloader as it is
functional code. This allows those required includes to perform as
best as possible in this situation.
I did some further work tidying up the form. I also just treat the popup like another plugin and moved all the config into the plugin.
This still needs help buttons everywhere now!
This new messaging system replaces all the various email_to_user() calls.
They are now replaced by events triggers, and the messages are then
processed centrally according to user preferences and sent to one or more
processors (email, popup, jabber etc...)
This code is not finished yet, a lot of work still has to be done on the
interface. However, the basic structure is there and should be working.
Luis and I will be reviewing and polishing this heavily in the next few weeks.
