On edit quiz page marks/reorder text box has zindex set, which should be considered by modal
window. Also, tab set is also using zindex for active node.
Now we show the attempt state separately, so there is no need to show
Grade: Attempt still in progress - especially since we were showing that
for abandoned and overdue attempts which is just wrong.
Includes:
* update checker refactored to \core\update\ namespace
* plugininfo classes refactored to \core\plugininfo\ namespace
* plugin_manager renamed to core_plugin_manager
* redirect back to original page after plugin uninstall
* fixed assign subplugin uninstall
* move assign subplugins under the assignment in admin tree
* fixed plugininfo for all question related plugin types
* auth uninstall support
* added missing block dependencies
* added theme uninstall
* subplugin types are following the plugin on plugin overview page
* several performance improvements in plugin manager
* new warnigns when plugininfo are outdated or missing
* multiple fixes and other improvements
We now compute the average CBM score, accuracy, CBM bonus and enhanced
accuracy, both for the entire quiz, and for just the questions answered.
Note that these calculations must work correctly in the presence of
descriptions, ungraded questions, and manually graded questions. For
example, imagine a essay added at the end of the quiz "Summarise what
you learned attempting this exercise." This might have max mark zero or
non-zero. The CBM statistics just ignores questions like that.
At the top of the quiz reivew page, there is a table that summarises
infomration about the quiz attempt as a whole. For some question
behaviours, we would like to be able to add additional information to
that summary.
This commit introduces a generic method for the behaviour to provide
summary information about an entire question usage.
It was always a bit of a hack to use static methods on the
qbehaviour_whatever classes to return metadata about the behaviour. It
is better design to have real qbehaviour_whatever_type classes to report
that metadata, particularly now that we are planning to add more such.
For example, inheritance works better with real classes. See, for
example, the improvements in
question_engine::get_behaviour_unused_display_options().
This change has been implemented in a backwards-compatbile way. Old
behaviours will continue to work. There will just be some developer debug
output to prompt people to upgrade their code properly.
as well as for first or all attempts.
This commit drops a database table and then recreates it. This is in
order to be able to have some new columns in the table be NOT NULL with
no default value, which would not be possible if I added fields to an
existing table.
The quiz_statistics table is used for caching calculated values only
and thus we can safely drop it and recreate it.
quiz_question_statistics_stats renamed to question_statistics_calculator
separate class question_statistics used to store calculated stats
and api changed, also code generally cleaned up.
