- Modified SQL in get_data() to get the activity completion of all course modules without calling get_fast_modinfo() to reduce the DB queries.
- Building activity completion cache for the whole course in one time instead of building the cache for each course module by passing $wholecourse = true to get_data()
This adds the requirement for activities supporting custom completion to
specify the order all completion conditions should be displayed for that
activity. It also implements the sorting that takes place.
This commits adds a fallback for plugins which does not have
custom_completion implementation.
For those cases, it will search for {modulename}_get_completion_state
callback in the plugin and call get_overall_completion() method in
cm_completion_details class to get the overall completion state for
a course module and user.
