There is a new implementation of require_js in lib/deprecatedlib.php,
based on $PAGE->requires.
There were a few other recently introduced functions in lib/weblib.php,
namely print_js_call, print_delayed_js_call, print_js_config and
standard_js_config. These have been removed, since they were never in
a stable branch, and all the places that used them have been changed
to use the newer $PAGE->requires->... methods.
get_require_js_code is also gone, and the evil places that were calling
it, even though it is an internal function, have been fixed.
Also, I made some minor improvements to the code I committed yesterday
for MDL-16695.
All that remains is to update all the places in core code that are
still using require_js.
(This commit also fixes the problem where the admin tree would not
start with the right categories expanded.)
I have collected code that used to be in lib/adminlib.php, lib/accesslib.php and user/selector/lib.php into a new admin/roles/lib.php file.
And I added standard GPL and Moodle comments to all the files in admin/roles.
This implements the page showing the table. It is not yet integrated into the tab bar. To try this, go to an Assign roles page (one with URL .../admin/roles/assign.php?contextid=...) and change the 'assign' to 'explain'.
Also, improved the comment that explains to subclassers what they have to do, and fixed get_selected_users, so if the number of selected users is greater than the max number of users to show, it still works.
At the same time, I took the opportunity to try to work on some of the usability issues on this page. Note that I have not quite finished! So don't comment until tomorrow.
In the course of doing this, I also did: half of
MDL-11529 Show the number of assignees of each role in the change role dropdown on this page.
MDL-17067 Make it clear in the UI that admins are not allowed to unassign themselves.
