> Key: MESOS-2279
> URL: https://issues.apache.org/jira/browse/MESOS-2279
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.21.0, 0.21.1
> Reporter: Jie Yu
> Assignee: Vinod Kone
>
> For example, when a future has transitioned into READY state, all onDiscard
> callbacks should be cleared to avoid potential cyclic dependency and memory
> leak. For instance:
> {noformat}
> Promise<Nothing> promise;
> Future<Nothing> f = promise.future();
> f.onDiscard(lambda::bind(&SomeFunc, f));
> promise.set(Nothing());
> {noformat}
> The above code has a cyclic dependency because f.data has a reference to the
> future inside an std::function which has a reference to f.data.
