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.
- Removed redundant query to analytics_predict_samples
- Analysers API now uses recordsets to iterate through the analysable
elements. They take the last analysed time into account.
- New method for targets so there is no need to always update the last
analysis time. Useful for lightweight targets.
This had a relatively simply check for course profile visibility, which
meant that users in separate groups could see one another's profile.
This has been replaced with the more correct check in
user_can_view_profile().
Significant string changes:
* importgroups_help,core_group - Correcting optional fieldnames
(removing picture, hidepicture and adding groupidnumber, groupingname
and enablemessaging)
* penaltyforeachincorrecttry_help,core_question - additional paragraph
about scoring logic
* resultdownloadready,tool_dataprivacy - wording corrected (no need to
go to a download page)
* auth_dbfielduser,auth_db - varchar data type requirement
Purge cache just for the current user to avoid redirection when 2
simultaneous users try to sign up at the same time and some policy
has to be agreed.
The 'createduser' invalidation event has been removed also because
is not used any more.
Thanks John Azinheira for spotting it!
* External authentication mechanisms (e.g. via oauth2, etc.) don't store
password in the user table, so we shouldn't be requiring password in
such case when creating users via the core_user_create_users WS
function.
Default setting value for new instances is 0
Default setting value for existing instances is 1
to get same search results than before this setting exists
Setting messagingallusers = 1 for behat tests to simulate old versions functionality
