ExecuteToComplete and excpetion RRS feed

  • Question

  • Hi,

    I use the CCR as async library for my UI. When I have a long running operation (which eventually will do I/O) I have method with this signature:

    private IEnumerator<ITask> Operation(P1 p1, P2 p2)


    When the user click a button (or any other trigger) I use this code to initiate the operation:

    p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas} p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas; min-height: 11.0px} span.s1 {color: #1b39f5} span.s2 {color: #10a3ba}


    var donePort = new ccr.Port<ccr.EmptyValue>();

    Arbiter.ExecuteToCompletion(new IterativeTask(iteratorHandler), donePort);


            TaskQueue.Enqueue(ccr.PortExtensions.Receive(donePort, x =>


                  [handle run complete code]





    The problem is that if the operation method throw an exception donePort is never post a EmptyValue.

    I handle it today using Causality and handle post to the ExceptionPort on that Causality but I still like to know if it is by design that the donePort never get posted?


    Thank you,

  • Hi Ido, the donePort should be posted whether the handler completes cleanly or not. Is it possible you could post more detail on what the faulting code actually does?
