revamped task handler unit tests
found bug when a False persistent kwarg is passed to the add method. Resolved it.
All evennia unit tests pass. Default run level and run level 2.
Added method remove_all to task handler. (intended for unit testing)
Created a method to mimic a server restart for the purpose of task handler.
test_delay unit test passes.
Task handler will automatically remove uncalled but canceled from task handler. By default this will not occur until a canceled task has been uncalled for 60 second after the time it should have been called. To adjust this time use TASK_HANDLER.stale_timeout. If stale_timeout is 0 stale tasks will not be automatically removed.
This is not done on a timer. I is done as new tasks are added or the load method is called.
Added unit tests to test automatic removal. Including when it should not automatically removed. Both when it is too soon, or when the stale_timeout attribute is set to 0.
Created an object to represent a task.
This allows for the return of TASK_HANDLER.add or utils.delay to be an object that has callable methods. It has been created to mock the most common methods and attributes of a twisted deferred object.
Changed test_utils.test_delay for new usage.
Returned previously changed modules slow_exit, tutorial_world.objects and portal.telnet to their previous states. As the return of utils.delay can be used as if it were a deferred.
All evennia unit tests pass
TaskHandler.do_task is now state aware and can be called manually.
It can now return the callbacks returns.
added unit tests to verify early callback is functional. Both persistent and non-persistent tasks.
All evennia unit tests pass.
Created task handler methods to cancel a task and check if a task exists.
Modified unit tests to use these and test methods.
unit test test_delay passes.
TaskHandler.remove method now functions. Previous it would have removed the task from the TaskHandler.tasks dictionary, but never canceled the task. Making the "remove a persistent task without executing it" incorrect. Previous there was no method to get a persistent tasks's deferral instance, which was likely why TaskHandler.remove was not used within the module.
Added unit tests to test TaskHandler.remove
