Adds a new 'Gradual reindex' link to the search areas page for each
area. When clicked, this takes you to a confirm prompt, and then
adds each context from that search area to the indexing queue.
The search areas page now displays the 'Additional indexing queue'
(if it is non-empty). The table shows the first 10 items in the
queue, and it also indicates the total number in case there are
more. (I don't think people really need to see the entire
contents of it, so I didn't implement paging.)
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.
This new API returns a list of contexts for each search area. This
allows the areas to be reindexed in a sensible order (roughly
speaking, newest first) and also allows this to be controlled by
each area.
An implementation in the forum module means that forums are ordered
by the date of the most recent discussion, so that active forums
will be reindexed early even if they were created a long time ago.
The patch increases the maximum supported precision (total number of
digits) for numeric (decimal) fields to 38 digits (current limit on
Oracle and MSSQL).
Additionally, we add our own limit for the whole number part of numeric
fields so they are no longer than integer fields (20 digits). This is to
make it easier to eventually convert from one field type to another.
Note that PHP floats commonly support precision of roughly 15 digits
anyway.
We are going to unify the maximum supported precision of all numeric
fields to 38 digits (which are the current Oracle and MSSQL limits). Get
rid of hard-coded exceptions for longer fields.
* We need to have unique feature names for our Behat tests.
* I also removed the custom Behat tag @role_visibility as we only allow
Behat tags with the component name in Frankenstyle format.
The upgrade step was creating a column with no default, which is different to the structure
for a new install. This was picked up by the magical cibot.
