While strictly we don't nedd to provide an upgrade path for master,
any dev/integration site already using some of the 3.7 new tagets
in models will break (class rename/move) if we don't perform the
update of all them.
This commit takes rid of the previous upgrade step, only performing
the update of a couple of targets and now supports all the (5) targets:
- course_dropout
- course_competencies
- course_completion
- course_gradetopass
- no_teaching
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.
This patch adds asynchronous backup and restore functionality
to Moodle. This is an optional feature and is not enabled by
default. It can be enabled by site administrators.
Asynchronous backup and restores are actioned by the Moodle
adhoc task API. The progress of backup and restores is
displayedin the Moodle UI. Users can also be sent a message
when a backup or restore operation completes via the
Moodle messaging API.
Due to the bug, the no_teaching model might have been marked as
not-trained in the database. Static predictions models (i.e. those using
a target based on assumptions, not facts) are always considered as
trained. If they were marked as not-trained, the prediction scheduled
task would skip them and they would produce no predictions.
Ideally, such a fix should be done for all static models. But there is
no easy way to do it during the upgrade where accessing the analytics
API is not possible. I don't think there are many models out there that
would be affected by this so this seems to be good enough solution for
now (and the future ability to reset models will cover the rest).
