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.
Also, added WS new return parameter candeletemessagesforallusers in get_conversation
and send_instant_message and added API support. This will be used to check
if the user can delete all messages in the conversation.
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.
Added new MESSAGE_CONVERSATION_TYPE_SELF type for self-conversations
and upgraded legacy self-conversations to the new type, removing
repeated members in the message_conversation_members table.
Besides, from now, a self-conversation will be created by default for
all the existing users.
All the self-conversations have been also starred and a default message
will be displayed always to explain how to use them.
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.
* Fix bug for newly created conversations being added to overview page
* Fixed bug with use enter to send preference not updating correctly
* Fix unit tests
* Fix race condition loading new messages while conversation resetting
* Fix ordering and rendering of messages with same timestamp
* Fix missing privacy info in get_conversation web service
* Fix linting errors
* Improve bulk message rendering
This should depend on the messagingallusers setting and, if false,
should only return those users having a profile the searcher can see.
If true, then any user can be returned. There is no requirement to
have a conversation with the user.
