- move cron to clean up old cache records move code and
rename classes
- further review of the quiz reports statistics code
- starting to separate calculations of quiz stats, question stats and
response analysis
- introduce hashcode db field for cached stats convert
- code to use qubaids hashcode for caches
We just drop the old tables (including previous upgrade steps) and
re-create the new ones, because these tables just cache calculated
statistics. No important data is stored in them.
With qtype_ddmatch installed, the unit tests for qformat_blackboard_six
fail as they generate ddmatch questions instead of match ones. This
patch checks for ddmatch and changes the test to expect that instead if
its installed.
I think this used to work because mod/forum/lib.php used to be included
everywhere, and in turn included lib/formslib.php. We should declare the
dependencey explicitly.
This slighly changes the format for the way answers are stroed in the DB
in the case where there is some HTML content, but no files. This should
not cause any problems.
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.
At the moment, when attempt is built on the last one, "not yet answered"
message is shown, which confuses many people. This patch modifies the state to
"complete" for attempt based on previous and modifies the output string.
Many thanks to Tim Hunt for guiding me through quiz infrastructure and some code
suggestions.
Sometimes it is necssary to display parts of a question outside of an
attempt. For example for staff review. When displaying the question, we
need to handle images in the question text. In the past there was a
mechanism for this that could only cope with the question text.
This commit introduces a new method that can handle displaying any
part of the question content.
This commit intentionally does not upgrade the parts of the system that
use the mecanism. That is so that this commit can be used to demonstrate
that backwards-compatibility works. The next commit will upgrade the
callers.
- Escaping steps arguments redirected to other steps
- Adding normalized-space() in all contains() assertions
- General xpaths review
- Convering provided xpath text strings to xpath literals
to avoid problems with arguments containing both single
quotes and double quotes
