The useridfrom would normally be a foreign key to the users table. But
it can also contain some extra negative values with special semantics
(-10 or -20 for no-reply or support user). Therefore we can't make it a
foreign key and the index must be created explicitly.
This commit is part of work on Custom fields API,
to minimize commit history in moodle core the work of a team of developers was split
into several commits with different authors but the authorship of individual
lines of code may be different from the commit author.
This chagne adds support for a new feature known as Context Locking.
This allows a context to be locked, thereby removing all write
capabilities for all users (including admin) for that context, and all
child contexts.
- Fixed reference to non-existent column 'timeread'.
- Fixed alignment issues.
- Fixed inconsistencies between upgrade.php and install.xml.
- Cleaned unit tests of unnecessary DB calls.
- Renamed 'get_does_conversation_area_enabled' to
'is_conversation_area_enabled' and moved to api.php.
- Replaced "$mform->elementExists('enablemessaging')"
check with a capability check.
- Removed the change of [] to array() in unrelated to upgrade code.
- Updated conversation 'timemodified' field when updating name.
- Bumped version based on latest master.
Allow NULL values for timecreated in both message_contacts
and message_users_blocked because there is existing data
that has no timecreated value associated with it.
The composite index over the fields contextid, commentarea and itemid
helps the comments API to load all comments for the given area
effectively.
The index over the userid field helps the privacy API to load all
comments by the given user.
If enabled $CFG->allowcohortthemes, then themes can be set at the cohort level.
This will affect all users with only one cohort or more than one but with the same theme.
The default theme order will be: course, category, session, user, cohort, site.
Adds indexpriority field to the database table which holds a queue of
indexing requests. This allows for potentially large area reindexes
to have a lower priority, so as not to halt the special indexes that
run after a course restore.
New API \core_search\manager::request_index($context, $areaid = '')
adds the given context to a list which is intended to be indexed
later by the scheduled task.
