* New table role_context_levels
* Populate table with defaults on install
* Populate table on upgrade with the same defaults, plus any additional ones needed to ensure all the role assignments already in the database are allowed.
* Change get_assignable_roles to respect these settings.
* UI for these settings on the add/edit role form.
* Save these settings when a role definition is saved.
* If in a context, there are no roles you can assign, display a polite message.
* Back up these settings.
* Restore these settings. When resotring a <=1.9.x backup file, any newly imported roles are set to be assignable at all contextlevels.
Restore not tested because it is broken in HEAD.
This is an initial implementation that is now at a working state, but with a few things left to do. It seemed like a good idea to commit it before leaving work on Friday night.
This new messaging system replaces all the various email_to_user() calls.
They are now replaced by events triggers, and the messages are then
processed centrally according to user preferences and sent to one or more
processors (email, popup, jabber etc...)
This code is not finished yet, a lot of work still has to be done on the
interface. However, the basic structure is there and should be working.
Luis and I will be reviewing and polishing this heavily in the next few weeks.
active by default at this time. Related help files are not included in this
commit, as they are being revised (see issue 15385) and will be sent in soon.
* renamed Preferences to "My report preferences"
* renamed Site defaults to "Report defaults"
* rename Change site defaults to "Change report defaults"
* reintroduced Inherit option to Grader preferences - Nicolas was right, it is not possible to implement preference overrides without it with our current get_pref inplementation
* new separate option in plugin selector "Course settings"
* moved displaytype, decimals and aggregation position to "Course settings"
* created new table grade_settings + related functions grade_get/set_preference()
* user report now uses grade_seq class instead of grade_item::fetch_all(); added preloading of grade items into grade_grade instances
* other minor bugfixing/cleanup/improvements
Please note that the Grader report preferences and its defaults must be resaved again - sorry.
MDL-11527 fixed warning from $CFG->defaultuserroleid when installing and upgrading
+ removed reusing of previous contexts in has_capability() and get_context_instance() because it was hiding critical errors when context was false, not specified, etc.
+ tweaked roles defaults - faster and defaults are applied when roles exist
+ SYSCONTEXTID may be specified in config.php to eliminate 1 db query
+ static context cache is now reset after rebuilding of context paths
+ path field in context table is now nullable - pg compatibility requirement
+ other minor fixes
