* Rename filter base class from filter_base to moodle_text_filter
* Remove unnecessary explicit constructors in moodle_text_filter
subclasses
* New filter_manager class, rather than static methods in filter_base
* Move some logic out of weblib, and into filter_manager
* Count filtering ops when $CFG->perfdebug on, via
performance_measuring_filter_manager
* Kill unused filter_string function. Petr said it should have been
private to weblib
If Google can do something like http://translate.google.com/, surely we
can do something just as good in Moodle. Here is a first attempt. It is
a bit rough around the edges, and only a couple of target lananguages
have been implemented so far. (More and better attempts welcome!)
In order to ensure that this gets adequate testing, I have made sure that
it gets turn on by default. However, if you really don't like it, you can
turn it off under Administration > Development -> Experimental settings.
This is part 1 that does the back-end:
1. New table role_allow_switch.
2. Upgrade that copies all the allows from role_allow_assign, and then drops the old CFG->allowuserswitchrolestheycantassign.
3. Old function get_assignable_roles_for_switchrole renamed to get_switchable_roles and changed to use the new table. Fixes MDL-18604 in HEAD.
4. Switch callers to use the new function name.
5. Unit tests for this new function.
6. To make those unit tests work, new switch_global_user_id and revert_global_user_id methods in UnitTestCaseUsingDatabase for toggling $USER->id.
I still need to do the editing interface under Administration ► Users ► Permissions ► Define roles. That will be done as a second commit.
Thanks to Daniel Neis for the patch.
I checked the standard theme, and I don't see any rules there that would erroneously apply to these class names in paging bars.
Bugs: MDL-17479, MDL-16426, MDL-16063, MDL-16013, MDL-15658, MDL-15556, MDL-15161, MDL-14925, MDL-13742, MDL-11557.
* Simplify category editing permissions to just moodle/category:manage and moodle/category:seehiddencategories.
* Enforce those correctly. (Note MDL 17502 is still outstanding.)
* Don't screw up category sort order when you just edit name or description.
* Niceties like where redirects go when you cancel or submit forms.
* Make sure a global course creator can see the site admin block.
* Don't allow a category to be made the child of one of its children!
* General code cleanup to bring key files more in line with best pracitice.
Apologies for the fact it is one big patch, rather than a series of smaller patches. However, categoryedit.php, category.php and index.php where in pretty bad shape and needed significant cleaning up. categoryedit.php, in particular, was almost completely rewritten.
Merged from MOODLE_19_STABLE.
