There are multiple issues with Moodle files containing empty or blank lines
(lines consisting of white spaces or tabs only) and/or white space before or
after the PHP open and close tags, notably with config.php and theme files.
* improved handling of dirty contexts in general - caching, switching in cron, marking, loading, etc.
* role_assing() and role_unassign() now marks dirty contexts because we use has_capability() in this function - we can not do it later outside to speedup bulk operations
* fixed some inline docs
* fixed notice from rs closing
* removed cached $CONTEXT from has_capability() - $context is now required parameter; this was hiding serious bugs when context did not exist or ppl passed false as parameter
* removed some ===, we can not use these on function parameters - we must support ints, strings, '', nulls, etc. - this could be a source of really dangerous bugs in future
* some other improvements and fixes - documented inline
* Display the grouping a course module belongs to on the course page - for course managers only.
* When adding users to groups, display the groups a user already belongs to.
* Added an overview report that shows groupings, groups and members for a course.
* Added a dialogue to automatically create groups and assign members based on either the number of desired groups or the number of desired users per group.
Very last caller to rebuild_context_rel() and any XX_context_rel()
function. move_category() already takes care of calling
context_moved(), which does the required context.path maintenance.
Addresses MDL-11219
Fix a thinko in a variable assignment that prevented us from grabbing
the correct roles as managers. Addresses Yu's report at
MDL-11182 admin shows up as teacher.
get_my_courses() now defaults to a much leaner dataset, but accepts an
array of "additional" fields we want. So ask nicely for the summary,
so that we can print_course() later with it.
New categories need a context immediately, and for top-level
categories, they also need to taint the "root" context to trigger
a reload of $USER->access.
This fixes problems with creation of initial courses(MDL-11178),
duplicate misc categories, etc.
- The code uses the system context a lot. Declare
$sysctx at the top and use it.
- If the category has a context property, use it
(saves 1 DB query per category displayed)
The DB costs of this page in editing mode are
- ~100 DB queries for fix_course_sortorder()
- ~50 DB queries for the categories listing
If we rewrite both to lose the recursion, we could resolve the
page in perhaps 5 DBq.
