- Always make sure the elements in cache are sorted so we need to remove only elements in the beginning of array
- Remove expired elements from session store to free memory
- Minor bug fixes
To constrain memory we only cache a single question's answers.
A quiz must display this many answers, so it will not result
in undue memory pressure.
We now match on the full answer text rather than the first 255
characters. This removes the risk of matching questions with the
same start.
This issue makes several fixes for the session loader and the session store.
* maxsize argument now works for session caches.
* fixed performance hole when interation occurs frequently.
* fixed cache purge bug occuring when multiple caches are defined before being used.
* improved lastaccess handling.
When doing Each attempt builds on last, we need to copy any response
files into a draft file area, and then re-save them.
While writing the unit test for this, I had to deal with a todo in the
question engine so that questions with files in the response could be
unit-tested.
I also found an fixed a bug with qtype_essay_question::is_same_response
and fixed some notices in the existing essay/manual graded unit tests.
List of fixes:
* Add a simulated drag start event to fix problems with block drag and drop that
were expecting it.
* Add an access-hidden title for the General section in a course format. This
is used to provide the text for the drop region (better than the first activity in the section)
* Changed the text in the list to 'Move to "General"' instead of 'Move after General'. This
makes more sense for activities when you have a list of activities and sections together.
Fixes display issues with the filepicker dialogs that were
converted to M.core.dialogue.
Note: These dialogue use table based layouts and the table width is not
counted in the form that it sits in. I have changed the dialogues to have
a wider width but for really small screens this causes horizontal scrolling.
The only solution for that is to rewrite all the filepicker/filemanager dialogs
to use css for layout.
