This is part 1 that does the back-end:
1. New table role_allow_switch.
2. Upgrade that copies all the allows from role_allow_assign, and then drops the old CFG->allowuserswitchrolestheycantassign.
3. Old function get_assignable_roles_for_switchrole renamed to get_switchable_roles and changed to use the new table. Fixes MDL-18604 in HEAD.
4. Switch callers to use the new function name.
5. Unit tests for this new function.
6. To make those unit tests work, new switch_global_user_id and revert_global_user_id methods in UnitTestCaseUsingDatabase for toggling $USER->id.
I still need to do the editing interface under Administration ► Users ► Permissions ► Define roles. That will be done as a second commit.
I did not fix all the DB problems in search, there are too many there for me to be prepared to clean up other people's mess.
(For once, it was not me making this mistake ;-))
This is not as ambitious as the abortive FakeDBUnitTests scheme, but this one works for simple cases.
There is a new test case class UnitTestCaseUsingDatabase to inherit from. I hope it is sufficiently well documented in its PHPdocs.
* It users $CFG->unittestprefix.
* You can access that database using $this->testdb.
* That database is empty by default, you have to call create_test_table to create the ones you want, and drop_test_table to clean them up in the end. The table definitions are read from the XMLDB file.
* When you are ready to call real Moodle code that users $DB, call switch_to_test_db and then revert_to_real_db when you are done.
* If you forget to call drop_test_table or switch_to_test_db, the class will attempt to clean up after you, but will also print rude developer debug messages telling you not to be stupid.
* There is also a load_test_data method for populating a table from an array.
The is an example of its use in lib/simpletest/testunittestusingdb.php.
Instead we have a new $ACCESSLIB_PRIVATE for all caching. Regrettably, the only way to make this work in PHP (other than rewriting everything to be methods of a class rather than functions) is to make this a global variable. However $ACCESSLIB_PRIVATE should not be thought of a global, it is a private implementation detail of accesslib.php. (And there is a comment saying that.)
There is a new function accesslib_clear_all_caches_for_unit_testing(). In a unit test, you need to call this at the start of your test method, before you set up any test data, and again at the end, after you have discarded all your test data.
This new $ACCESSLIB_PRIVATE subsumes the old $ACCESS, $RDEFS and $DITRYCONTEXTS globals.
Also, I took the opportunity to refactor the (inconsistently) duplicated code for adding a context to the caches code into a cache_context function.
I don't know why the quiz only logged every 10 minutes. No other part of Moodle worked like that. However, it has always been like that and I did not have a good reason to change it until now.
What was a problem becuase it made it harder to catch people doing a primitive DOS attack against the server by hitting Reload repeatedly.
The block incorrectly links to site profile in the current pageid.
This doens't make sense in a number of different scenarios, but
most notably if the user who messaged isn't enrolled in the current
course. Instead link to the profile at site context like the messaging
popup does.
Fixes: MDL-18279 MDL-6890 MDL-5887
merged from MOODLE_19_STABLE
This is a minimal fix for MDL-18554, I have just added a cancel button and made it work.
The more substantial part of this is MDL-17454, trying to make the quiz editing screen behave appropriately when shuffle questions is on. I am sure Olli will have opinions about this and want to change it further. Rought summary:
* When shufflequestions is off, never restrict manual paging, even if questionsperpage is set.
* When shuffle questions is on:
** Always display the quiz with the defined number of questions per page.
** Remove controls to add things except at the end of the quiz.
** Disable most of the order and paging tab, but still allow the question list to be reordered, in case that helps teachers track which questions they have added.
** Still allow questions to be reordered on the edit tab, but when moving the top question on a page up, reorder with the previous question, rather than moving to the previous page.
* Change the status bar, so that the yellow highlight is reserved for alert information. The more informative stuff is now plain, and moved to under the title. To my mind that associates it more closely with the quiz name. Also it moves Total of grades and Maximum grade closer together.
* JavaScript cleaned up. I learn more about YUI every day.
* Some PHP code clean ups that I forgot to commit separately before making substantive changes.
* change the wording of the settings.
* add a repaginate now checkbox (disabled if shuffle is on).
* JavaScript to automatically check the checkbox when qpp changes.
* (remove some irrelevant return value checks now we use exceptions.)
