CHANGE HISTORY

18 November 2017. 3.2.2

• Added an experimental script /question/type/coderunner/downloadquizattempts.php to dump the database info on all student quiz activity to a spreadsheet. The data includes the submitted answers to both prechecks and checks, with timestamps. The export format is experimental and may change in the future. A Python module quizattempts.py is included too and is the recommended way to deal with the quiz attempt download spreadsheet.

• Bug fix: a submitted answer of '0' (an edge case that might be possible when student answer is not code) was being rejected as an empty response, due to the use of PHP's empty function. Thanks to David Bowes for the fixes here.

• Added SQL prototype and 2 simple samples (experimental).

• Bug fix: testsplitterre and allowmultiplestdin fields of author form were not being correctly initialised when a new combinator question type was downloaded with AJAX.

22 August 2017. 3.2.1

• Bug fix: result table cells not being sanitised since commit of 19/5/17
• Bug fix: combinator template grader result tables were not hiding hidden rows from students but merely colouring them darker.

6 August 2017. Version 3.2.0

• Add allowmultiplestdins option for advanced use of combinator templates. This option disables the usual behaviour of running combinator templates once for each test when any tests have standard input defined. When enabled, the combinator is given all testcases (as when standard input is not present) and must itself manage the switching of standard inputs between tests.
• Bug fix: All-or-nothing checkbox was not labelled when using Clean theme
• Bug fix: All-or-nothing grading was not working with per-test-case template graders - students were getting partial marks.
• Generate a validate-on-save error message when using a combinator template grader that has a test-results table.
• Change Runtime Error message to just Error since it's not always clear what is runtime versus compile time.
• Change DB type of templateparams to text (was char(255)) to allow for more elaborate template parameters.
• Use text area for template params rather than a one-line entry field in order to cater for longer multi-line template parameters
• Update the uocprototypes.xml file in the samples directory to the latest version.
• Incorporate style changes from Open University (thanks Mahmoud Kassaei) for improved accessibility of the Ace editor.
• Fix bug in display of "For example" table when question has customised columns/headers.
• Improve various tests, e.g. fork bomb.
• Some documentation updates.

23 May 2017. Version 3.1.5

• Major bug fix: when grading of questions when precheck enabled, if a student's last submission to a question prior to closing the quiz was a precheck that passed, the question would be marked correct.
• Bug fix: sample answer and answer preload fields of author form were not using the correct Ace language when the question type was first set.
• Bug fix: validate on save not working with support files on the first save of the question.
• Bug fix: Show Differences button was not working in Edge browser.
• Bug fix: questions with precheck=selected were not being correctly saved in course backup.
• Various documentation and error message tweaks + code tidying.

19 March 2017. Version 3.1.4.

• Fix broken code in some of the sample files, update others.

2 March 2017. Version 3.1.3

• Fix occasional mishandling of whitespace by Show Differences button.
• Fix bug (introduced in 3.1) in display of hidden test cases to students (rather than being suppressed, the hidden test cases were being displayed as repeated versions of the preceding visible test).
• Refine handling of Jobe sandbox errors: improve error messages and ensure no penalty is applied.
• Replace term "Pre-check" with "Precheck" throughout.

1 February 2017. Version 3.1.2+.

• A couple more tweaks to improve appearance with Boost theme
• Add administrator script to analyse prototype usages in a course (run script /question/type/coderunner/prototypeusagesindex.php)
• Fix crash if user attempts to validate a new prototype question.

26 January 2017. Version 3.1.2.

Minor updates and bug fixes including:

• Fix broken layout of question authoring form with Boost theme (V3.1.1)
• Fix bugs in PHP and NodeJS question types
• Add Twig STUDENT variable (thanks David Bowes)
• Fix ACE editor gutter showing through Moodle help popups (thanks Tim Hunt)
• Various documentation updates.

6 January 2017. Version 3.1.0.

Another major refactoring with some significant new features including:

• A 'Precheck' capability, which presents students with an extra button (beside the 'Check' button) that gives a penalty-free submission with limited checking as defined by the question author.
• An answerbox preload capability, allowing the question author to define some initial text to appear in the question answer box.
• Question authors can request that the sample answer be validated whenever a question is saved.
• Simplification of the template mechanism, combining the combinator template and the pre-test template into a single template plus an 'iscombinator' boolean.
• Reworking of the Show differences button, so it's now implemented entirely in JavaScript, removing the complication of having to specify it via the column header.
• Addition of C++ 'write-a-function' and 'write-a-program' question types
• Improved accessibility for visually-impaired students (thanks to Tim Hunt). The tab key now moves focus through all fields in the question-answering form until the student types or clicks in a field. The Ace editor can be switched off with CTRL/M.
• A bulk tester allows administrators and authors to check that all question sample answers pass all tests (copied, with modifications, from the Stack question type).
• The 'Multiple tries' section of the authoring form has been removed and a penalty regime is now mandatory. This eliminates the confusion between the standard Moodle static question penalty (now hidden) and the formerly optional penalty regime. The behaviour of legacy questions is unaffected.

6 January 2017. Version 3.0.2.

• Add nodejs question type to built-ins.
• Fix bug in regular-expression grader when Expected has trailing new lines.

15 July 2016. Version 3.0.1.

Minor bug fixes, including:

• Use of Show Differences button with questions containing significant white space output resulted in premature line truncation and/or invalid html output
• Ace editor was not doing syntax highlighting for nodejs questions
• Several panels in question authoring form had monospace labels in Moodle 3.1

Also, the documentation for custom template grading has been rewritten.

8 February 2016. Version 3.0.0.

A restructured version of the code to conform to Moodle standards. The question behaviour has been deleted from this project, and is now a separate github project moodle-qbehaviouradaptiveadaptedforcoderunner. The moodle-qtype_coderunner project now contains just the question type code, which has been moved up the file hierarchy to the top level.

Discontinued features:

• The runguard sandbox and the Liu sandbox have both been dropped from this version. Only the Jobe sandbox is officially supported. The ideone sandbox remains as a proof of concept, only. It has never been officially supported.
• Support for upgrading from CodeRunner versions prior to 2.4 has been dropped.

New features:

• Built-in difference-checker to allow students to see how their output differs from the expected output (experimental feature)
• Updated documentation.

23 October 2015. Version 2.5.0.

Added a feature to display help on the selected CodeRunner question type to the question author in an unfoldable section on the question author form. The displayed help information is the question text from the prototype question that defines the question text.

Also added a feature that allows the author of a question using a template grader to abort the test process, e.g. if a pre-run check on the student's submission failed.

15 September 2015. Version 2.4.2.

Various bug fixes, most notably to fix broken export of custom question prototypes. Other minor changes and bug fixes include:

• Minor documentation tweaks, e.g. a warning on the perils of duplicating question prototypes and correction to regular expression grader help.
• Fix broken styling of result table with Moodle 2.9 (odd/even row colours weren't happening).
• Improve the error message issued if a prototype fetch fails.
• Fix bug that caused datafiles to get lost when a question was moved to from the special "Default fo quiz" category.
• Improve error message from JobeSandbox e.g. from network failures.
• Fix incompatibility with older (pre 5.4) versions of PHP
• Fix wrong error message issued on inconsistent test cases.
• Fix bug in initialisation of 'ordering' form fields with >15 test cases.
• Remove some obsolete question types.
• Add some new question types to built-ins and to U of Canterbury set.
• Add some demo questions for new users.
• Fix PostgreSQL incompatibility (thanks Arnaud Trouvé)
• Fix bug in question export when multiple prototypes with the same type name exist in different contexts.

29/1/15. Version 2.4.1.

• Added code to support use of an API-key when accessing a jobe server. Fixed bug in advanced question authoring interface - combinator template was no longer being disabled when per-test template was edited.

Dec 2014/Jan 2015. Version 2.4.0.

Refactored code to conform to Moodle style guidelines. Added functionality:

• Files can now be attached to prototypes
• An 'ordering' field associated with each test case allows easy reordering of test cases
• Use of Ace code editor for template editing
• Prompt for disabling combinator template when per-test-case template altered
• Improved ability to pass compile and run parameters to Jobe sandbox
