* 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
* in_null for decimals defaults checks
* store letter settings only in database - no cfg settings
* separate configuration page for letters only - pluginselector+admin tree
* new capability to manage grade letters - similar to scales and outcomes
* added grade_letters db index
* grade letters related minor bugfixing
Issue:
Teachers can edit grader report preferences (including switches for quickgrading and
quickfeedback), but do not have access to the "Turn editing on/off" button, so they
can't do quickgrading.
Solutions:
1.Decouple the quickgrading and quickfeedback modes from the editing mode,
and turn them on/off through the preferences page. New capability: moodle/grade:edit
* preferences: don't show quickgrading if no capability grade:edit
* If quickgrading is switched off as a preference and user doesn't have manage cap, show edit icons around grades when in editing mode
The number of submissions in the Group average and Course average calculations
should be shown in brackets. (submissions) should be added after the Group average
and Course average labels.
Solution:
new grader report preference (Display number of grades in average cells).
