In the case where either a question_attempt had not steps, or a
question_usage had not question_attempts, the load_from_records methods
could get stuck in an infinite loop.
This fix ensures that does not happen, with unit tests to verify it. At
the same time, I noticed an error in the existing tests, which this
patch fixes.
These changes move the logic to the behaviour class, which is how things
should be.
It also makes it easier to re-use the code that displays the messages
like "Marks for this submission: 1.00/1.00. Accounting for previous
tries, this gives 0.33/1.00." in other places.
To try to make it clearer what is going on, I introduced a new class
qbehaviour_adaptive_mark_details to hold and document the data that the
behaviour needs to return, and the renderer can base its display on.
As far as my testing can tell (and there are new unit tests), this
commit does not change the existing behaviour.
This commit also replaces all the string concatenation that is going on,
which should help translators. At the moment, a few of the old strings
are still in the language file, and are used in the unit tests to verify
that the behaviour has not changed.
Thanks to Oleg Sychev for making a helpful suggestion about the API.
The test data was wrong, and was triggering the work-around code that
MDL-32062 introduced. I fixed the test data.
Also, I fixed one of the tests, that had been broken.
The code to upgrade attempts from before Moodle 2.0 to 2.1 created
attempt data that was not exactly the same as a new attempt created in
2.1+. This did not matter very much - revew and the quiz reports all
worked OK - but it broke on re-grade.
These changes detect the problem data in the re-grade code, an apply a
work-around so that the re-grade gives the correct result.
- Added possibility for editor form field to specify return_types (default FILE_INTERNAL | FILE_EXTERNAL | FILE_REFERENCE)
- For assignment, workshop, quiz essay submissions and form posts do not allow FILE_REFERENCE
- Fixed mod_resource return_types, reset them to default, because filemanager does not know how to work with FILE_EXTERNAL links
- when file is uploaded in php, the tmpname does not have initial extension and mimetype recognition by extension fails
- another issue is that import form for questions fails with fatal error when it should just say that field is required
