Subject: Adding some serious checks to make Moodle break when there is any
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=937b63ee52b1daf90bb3ddf23bd2ae1ff224eda3;p=moodle.git

Adding some serious checks to make Moodle break when there is any
select, insert or update on user_students, user_teachers, user_coursecreators,
or user_admins (once roles is installed), because they should not be used
at all and we will drop them soon.
