Upgrade helper functions This file is used for special upgrade functions - for example groups and gradebook. These functions must use SQL and database related functions only- no other Moodle API, because it might depend on db structures that are not yet present during upgrade. (Do not use functions from accesslib.php, grades classes or group functions at all!)

| upgrade_mysql_get_supported_tables() X-Ref |
| Returns all non-view and non-temp tables with sane names. Prints list of non-supported tables using $OUTPUT->notification() return: array |
| upgrade_group_members_only($groupingid, $availability) X-Ref |
| Using data for a single course-module that has groupmembersonly enabled, returns the new availability value that incorporates the correct groupmembersonly option. Included as a function so that it can be shared between upgrade and restore, and unit-tested. param: int $groupingid Grouping id for the course-module (0 if none) param: string $availability Availability JSON data for the module (null if none) return: string New value for availability for the module |
| upgrade_mimetypes($filetypes) X-Ref |
| Updates the mime-types for files that exist in the database, based on their file extension. param: array $filetypes Array with file extension as the key, and mimetype as the value |
| upgrade_extra_credit_weightoverride($onlycourseid = 0) X-Ref |
| Marks all courses with changes in extra credit weight calculation Used during upgrade and in course restore process This upgrade script is needed because we changed the algorithm for calculating the automatic weights of extra credit items and want to prevent changes in the existing student grades. param: int $onlycourseid |
| upgrade_calculated_grade_items($courseid = null) X-Ref |
| Marks all courses that require calculated grade items be updated. Used during upgrade and in course restore process. This upgrade script is needed because the calculated grade items were stuck with a maximum of 100 and could be changed. This flags the courses that are affected and the grade book is frozen to retain grade integrity. param: int $courseid Specify a course ID to run this script on just one course. |
| upgrade_course_tags() X-Ref |
| This upgrade script merges all tag instances pointing to the same course tag User id is no longer used for those tag instances |
| make_default_scale() X-Ref |
| This function creates a default separated/connected scale so there's something in the database. The locations of strings and files is a bit odd, but this is because we need to maintain backward compatibility with many different existing language translations and older sites. return: void |
| make_competence_scale() X-Ref |
| Create another default scale. param: int $oldversion return: bool always true |
| upgrade_course_letter_boundary($courseid = null) X-Ref |
| Marks all courses that require rounded grade items be updated. Used during upgrade and in course restore process. This upgrade script is needed because it has been decided that if a grade is rounded up, and it will changed a letter grade or satisfy a course completion grade criteria, then it should be set as so, and the letter will be awarded and or the course completion grade will be awarded. param: int $courseid Specify a course ID to run this script on just one course. |
| upgrade_letter_boundary_needs_freeze($context) X-Ref |
| Checks the letter boundary of the provided context to see if it needs freezing. Each letter boundary is tested to see if receiving that boundary number will result in achieving the cosponsoring letter. param: object $context Context object return: bool if the letter boundary for this context should be frozen. |
| upgrade_standardise_score($rawgrade, $sourcemin, $sourcemax, $targetmin, $targetmax) X-Ref |
| Given a float value situated between a source minimum and a source maximum, converts it to the corresponding value situated between a target minimum and a target maximum. Thanks to Darlene for the formula :-) param: float $rawgrade param: float $sourcemin param: float $sourcemax param: float $targetmin param: float $targetmax return: float Converted value |
