- The get_conversation_messages has been added to the API and the WS
with the conversation identifier (convid) instead of the userto,
to let get conversation messages and the members involved.
- The cache has been also reviewed, to use the convid instead of the
[userfrom, userto] keys.
- The get_most_recent_conversation_messages has been added to the API
to update the cache when needed.
Add new messaging profile preferences to allow users to choose who
can message them:
- By default, users can select between 'My contacts only' and 'My
contacts and anyone in my courses'
- When $CFG->messagingallusers is enabled, a new option is displayed
also: 'Anyone on the site'. For users who have selected this option,
if $CFG->messagingallusers is disabled, the behaviour will be changed
to 'My contacts and anyone in my courses'
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.
- No longer use the Fibonacci sequence for delaying the timeout.
It is too aggressive.
- The backoff_timer AMD module now expects the callback AND the
backoff function to be passed to the constructor.
- Added ability to specify polling frequency in config.php.
- Added helper function to return the cache key.
- Reworded the parameters for clarity.
