This change addresses necessary adjustments to how OBV2.0 badges are
sent to backpacks, specifically to ensure compatibility and correct
functionality following recent updates to Canvas Credentials' conditions.
It ensures our badge integration continues to operate smoothly despite
these external changes.
The only backpack implementing OBv1.0 was Mozilla Backpack. It closed
in 2019 and their badges were moved to https://backpack.openbadges.org/
by Badgr.
However, as Badgr is supporting OBv2.0 too, it makes no sense keep OBv1.0
implementation in Moodle: it has caused some issues and over-complicates
current code.
The token information was not being properly cleared from the $SESSION.
As a result, certain errors were occurring when users attempted to
reconnect within the same session.
Use the "expand" parameter so the backpack returns nested public
information about each badge in a public collection. This saves 2 requests per badge and
fixes the problem where we don't have permission to see some public badge details.
This commit combines several changes:
* Show authentication errors.
* Show more detailed authentication errors
* When the site backpack is different to the user backpack, show a warning
* Do not duplicate the apiversion and backpackurls in each user backpack.
* Do not support different issuer information for each badge with Open Badges v2.
* Add obversion to assertion url
* Combine separate badges upgrade steps and bump the version number.
* Don't show private collections.
* Push the larger image size to backpacks (512x512).
* BADGE_BACKPACKURL is deprecated
* Don't use property alignments, only alignment
Upgrade the support for Open Badges 2 to support a real open badges 2 backpack.
Moodle can only talk to one backpack at a time, so after switching backpacks, users
will have to manually disconnect and then reconnect their backpack to the new one.
This commit combines several changes:
* Split classes into badges namespace
* Publish expiry data with a badge
* Publish badge alignments in badges exported to the backpack.
* Export the criteria for a badge to the backpack.
