Vitaly d7d1ed65a5 MDL-56653 enrol_meta: a single DB query in edit_instance_validation
The 'edit_instance_validation()' method checks for existing meta enrolment instances.
The fix replaces DB queries in a loop for each course with a single query for all courses.
Also, a new testing method 'test_edit_instance_validation_with_existing_courses()'
was added to /enrol/meta/tests/plugin_test.php to test if the new implementation
returns an error in case of trying to save the already linked courses in the 'customint1' field.
