In Moodle 2.1, there was a major DB upgrade relating to questions, and
it was possible to delay some of that upgrade. Now, those DB tables are
changing again, and the time has come to insist that all the updata has
been upgraded (or deleted).
Added XML import/export
Different randomsamatch questions in the same quiz can now pick the same
shortanswer question.
Images are not preserved if shortanswer question is deleted after being
used in a randomsamatch attempt.
If the validation failed, so the manual grading page was re-displayed
with a validation error, then any comment that had just been typed in
was getting lost. This fixes that.
Whether the comments on manually graded questions were visible to
students should have been controlled by the 'Specific feedback' Review
option in the quiz settings. However, the quiz was not setting
$displayoptions->manualcomment, so it did not work.
This was breaking with oracle master/master replication. Fortunately all
the places that needed to be changed were private to datalib.php. There
is still some ordering by id there, but only places where we want a
consitent, rather than meaningful, order, so that is OK.
The queries changed by this patch all have subqueries in aggregate
queries that pull out the latest step for a question_attempt. Those
queries used to look for MAX(id) but now they look for
MAX(sequencenumber). This is equivalent (for databases where ids always
increase with time, except for auto-saved steps. In the past, an
auto-saved step might have been considered latest. Now the latest step
will always be one that has been properly processed. You can aruge that
this change is an improvement. Anyway, it is a moot point. All these
queries are only used in reports which are run on completed attempts,
where there will not be any autosaved data.
Before this, autosave was only working to save data when a student went
back in to continue an attempt. If the student, having crashed out,
never went back in and continued the attempt, their auto-saved responses
were not used when the attempt was automatically finished. That was a
rather bad oversight, which should now be fixed.
In general aiming for compatibility with multiple browsers,
firefox, chrome and phantomjs to be more specific.
* Removing hardcoded waits
* Adding @_alert, @_switch_window and @_switch_frame tags,
to label actions that different drivers have problems with.
* Adding missing @_files_upload and @_only_local tags to features that
uploads files.
* Fixing a few wait for page ready what specified miliseconds.
* New methods to ensure elements (usual selectors), sections and editors
are ready to interact with
* Changing the select an option implementation to deal with the different
drivers implementations when listening to JS events.
When you followed the link to the question bank, the checkbox for the
"Show question text in the question list" option correctly reflected the
user's preference, but what was actually shown in the question bank did
not.
Teachers were typing patterns like
********************************<em>****************************</em>
which translates into a pattern like .*.*.*.*, which is very inefficient
to try to match, althought it is equivalent ot a single .*. At a certain
point preg was just giving up.
Since people actually do this, we should simplify the regex by treating
runs of * like a single *.
