In the core dml:
PostgreSQL connections now use advanced options to reduce connection overhead.
These options are not compatible with some connection poolers. The
dbhandlesoptions parameter has been added to allow the database to configure
the required defaults.
This item adds a setting to the logstore_database plugin to let you set the
same flag for your destination database - without it you won't be able to ship
logs to a postgresql database with a pgbouncer frontend.
This reverses the references used for global $USER and $SESSION,
the reason is that PHP does not allow references to references.
$USER is a reference to $GLOBALS['USER'] which means we cannot
put any references to it. Solution is to store the current user and session
objects in $GLOBALS['USER'] and $GLOBALS['SESSIOn'] are reference
them in $_SESSION.
This patch makes the session code behave the same way in CLI,
phpunit and normal web requests - this allows use to finally
unit test most aspects of the session code in Moodle.
