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.
This was supposed to be split into multiple commits to make it easier to understand
but I failed to do it properly. So this is the list of changes:
- New analytics_indicator_calc db table to store indicators calculations
- Reuse previous calculations during prediction/training; other models
previous calculations should also be reused as long as they belong to
the same sample (sampleid depends on sampleorigin), time range and indicator
- Allow bulk inserting of these calculations as this can hurt database performance
- Block the same analysable to be analysed for training and for prediction
- Use a new instance of the target and use it for is_valid_* functions
as using ::is_valid_sample can lead to problems if people
uses it to cache stuff
Now we only predict using the most recent range available, this means
that if someone upgrades to moodle 3.4 at three quarters of a course
we will only calculate the latest range, previous ranges were not
displayed anyway once more recent predictions were available.
This commit deletes all previous predictions :) this shouldn't be a
problem in master as we don't provide any guarantee, the alternative
(retrive sampleids from mdl_files) would have been slow and a waste of
time as well as require horrible code in an upgrade step (text fields
do not accept defaults nor we can use NOTNULL).
