Jie Yu commented on MESOS-807:
------------------------------
Found another bug that is related to this issue:
{code}
Future<bool> future;
Future<bool> func(int value) { return future; }
{code}
{code:title=Case 1}
void main() {
Future<int> f1;
Future<bool> f2 = f1.then(lambda::bind(&func, lambda::_1));
f2.discard();
}
{code}
{code:title=Case 2}
void main() {
Future<int> f1 = 10;
Future<bool> f2 = f1.then(lambda::bind(&func, lambda::_1));
f2.discard();
}
{code}
One would expect that
> Discard is not propagated in process::dispatch.

> Affects Versions: 0.15.0
> Reporter: Jie Yu
> Assignee: Jie Yu
>
> We would expect these two operations to behave the same:
> Future<T> f = p->foo();
> f.discard(); // Discards the future returned by foo().
> Future<T> f = dispatch(p, P::foo);
> f.discard(); // Currently, this will not discard the future returned by
> // foo(), only discards the dispatch promise's future.
