This affects the case when a badge is setup with the criteria "manual issue by role".
The non-editing teacher can see all participants of the course, when awarding a badge, even with SEPARATE GROUPS mode enabled.
With this change, when the non-editing teacher chooses a group, and searches for a user, the results are filtered for that group.
The same happens for "Existing badge recipients by group" when revoking a badge.
dirname() is a slow function compared with __DIR__ and using
'/../'. Moodle has a large number of legacy files that are included
each time a page loads and is not able to use an autoloader as it is
functional code. This allows those required includes to perform as
best as possible in this situation.
The badges feature allows to integrate Mozilla "Open Badges" to issue, assign,
manage and display digital badges in Moodle. This feature supports:
-- badge creation and issuing based on criteria
-- badge baking and verification service
-- direct pushing of internal badges to external backpack
-- interanl and external badge display in Moodle
-- Moodle block to display latest badges
