This Moodle question behaviour was created by Richard Lobb, University of Canterbury, New Zealand.

This question behaviour was created solely for use with CodeRunner: https://github.com/trampgeek/moodle-qtype_coderunner/. It provides the caching of question test results needed to prevent re-testing a student's code every time the result page is viewed.

To install, either [download the zip file](https://github.com/trampgeek/moodle-qbehaviour_adaptive_adapted_for_coderunner/archive/master.zip, unzip it, and place it in the directory moodle/question/behaviour/adaptive_adapted_for_coderunner. Alternatively, get the code using git by running the following command in the top level folder of your Moodle install:

git clone https://github.com/trampgeek/moodle-qbehaviour_adaptive_adapted_for_coderunner.git question/behaviour/adaptive_adapted_for_coderunner

For full install instructions, see the CodeRunner install instructions.

18/04/24. V1.4.3. Bug fix: regrading of quizzes run with adaptive-no-penalties would apply penalties. Also some code-tidying. 13/04/22: V1.4.2. Bug fix: a regrade while the sandbox was down, or after a question author had set the time limit to more than the sandbox would accept, caused submissions to be lost when a Check immediately followed a Precheck. 23/11/21: V1.4.1. Add support for "Give up" button (Time Hunt). Add 'graderstate' functionality for use by combinator template graders.

24/02/21: V1.3.9. Add quizbehaviour to step info. 31/01/21: V1.3.8. Add step info (numchecks, numprechecks and fraction) to response array so that question author can alter feedback accordingly. 11/02/20: V1.3.7. Set css class for correct styling of Precheck button. 25/01/19: V1.3.6. Fix bug in privacy provider (not working with pre-version7 PHP). 03/8/18: V1.3.5 Implement Moodle Privacy API (null provider).

28/4/18: V1.3.4 Change state string to "Precheck" after a precheck. [Thanks to Tim Hunt.]

2/03/17: Prevent penalties being applied when grading fails due to a sandbox error

6/01/17: Fix wrong penalty calculation when using penalty-regime on question with all-or-nothing grading turned off.

4/01/17: Fix bug - previous answers were not being correctly loaded into the answer boxes when "Each attempt builds on the last" was used.

9/11/16: Provide Precheck capabilities (an extra button that students can click to get a penalty-free run that provides limited checking of their code).
