Add specs to test if issue #655 is present: the handler of an interval
cannot successfully clear the same interval that generated it's
invocation.
The most direct test consist in setting an interval with a handler that
calls clearInterval over that same interval and make the clock tick for
double of it's period. If the issue is present the interval's handler
will be called twice. If the issue is not present, the first invocation
of the handler will avoid a second one (because of the clearInterval).
Another test is included in order to check if recurring scheduled
functions are rescheduled before being called. Doing this in the reverse
order is the exact cause of the issue.
All timeouts and intervals set during a tick were being scheduled to run
at delay + end-of-tick, instead of delay + time-of-outer-timeout.
Scheduled run-at times were shifted because currentTime was being
incremented before executing scheduled functions.
Additionally, the execute loop was iterating over a functions-to-run
array, created from scheduledFunctions before starting. Any changes to
scheduledFunctions were being ignored during the tick, and the next tick
would ignore any functions which should have been executed in the past.
The commit is a rewrite of DelayedFunctionScheduler, preserving the
public interface. Execution of scheduled functions updates currentTime
on each iteration, and each time takes the functions with the lowest
runAtMillis from the schedule, if they aren't higher than endTime.
- Will replace rake core_specs.
- Remove obsolete dependencies & files -- most of these were for build tasks we
are no longer using. Notably, rspec and spec_helper were deleted.
Jasmine spies now have a 'and' property which allows the user to
change the spy's execution strategy-- such as '.and.callReturn(4)'
and a 'calls' property which allows inspection of the calls a spy
has received.
* This is a breaking change *
There is a CallTracker that keeps track of all calls and arguments
and a SpyStrategy which determines what the spy should do when it
is called.
