-----------------------------
Assignee: Yan Xu
> Create a convention for a special "no sender" PID.
> --------------------------------------------------
>
> Key: MESOS-7786
> URL: https://issues.apache.org/jira/browse/MESOS-7786
> Project: Mesos
> Issue Type: Bug
> Components: libprocess
> Reporter: Yan Xu
> Assignee: Yan Xu
>
> In libprocess we have this "fire and forget" messaging semantics, (e.g.,
> MESOS-7753 and a few places in tests).
> Right now these kind of messages use an empty sender PID, i.e.,
> {{@0.0.0.0:0}} which is could fail some checks like MESOS-7401.
> At a high level I think
> - It's OK if libprocess messages don't have a sender actor, akin to the
> [no-sender|http://doc.akka.io/japi/akka/current/akka/actor/ActorRef.html#noSender--]
> concept in Akka.
> - However all remote messages should have a valid source address i.e., ip and
> port in its {{Libprocess-From}}.
> So we can create a special *no-sender* ID and just make sure real actors
> can't use this ID. The ID could {{\_\_no\_sender\_\_}} or simply {{\_}}? The
> UPID would then look like {{[email protected]:5050}}.
