What happens is that adding random questions used to set the timestamps
of these questions to the same value. This is fine in normal operation,
but it stuffs up the backup of that course, overwriting the question.
When the course is restored, the missing questions cause quizzes to
have lots of red notices like "Question not found".
Anyhow, this patch should safely fix older installations that may have
these duplicate questions lying around.
THANKS ELOY!
The code for reviewing an existing attempt is now separate
in review.php and now has a log entry of it's own.
The overview and regrade reports are now in separate subdirectories
under the "report" directory. Each has a primary "report.php" file
which implements the report as a class.
These existing reports are very simple, but now more complex ones
can easily be written. (I am about to do one).
created. Works OK after limited testing.
I've also renamed some strings to do with "Random Match", so that this
question type is now called "Random Short-Answer Match".
Later there will be a new 'Random Match' which randomly selects one of the
existing "Match" questions.
... this grade is used as the default grade when adding questions
to a quiz.
At the moment it's just so that some imported questions can have
different defaults, but a field should be added to all question
editing pages.
Moodle tables.
ie user -> userid in many tables, plus in user_students
start -> starttime and end -> endtime
I've just done all this as carefully as I could ... I don't think
I missed anything but it's pretty intensive work and I'd be fooling myself
if I didn't think I'd missed a couple.
Note that this version should pretty much be able to bootstrap itself
using PostgreSQL now ... but this is untested
