             Summary: process::Connection does not invoke the disconnected callback when remote process exits
                 Key: MESOS-4153
                 URL: https://issues.apache.org/jira/browse/MESOS-4153
             Project: Mesos
          Issue Type: Bug
          Components: libprocess
            Reporter: Anand Mazumdar


The {{disconnected}} callback is never invoked when a local/remote libprocess {{process}} terminates. Here is a sample test that shows that the returned future from {{disconnect()}} is never fulfilled.

{code}
TEST(HTTPConnectionTest, Disconnected)
{
  Option<http::Connection> connection;
  Future<Nothing> disconnected;

  {
    Http http;

    http::URL url = http::URL(
      "http",
      http.process->self().address.ip,
      http.process->self().address.port,
      http.process->self().id + "/get");

    Future<http::Connection> connect = http::connect(url);

    AWAIT_READY(connect);

    connection = connect.get();

    disconnected = connection->disconnected();
  }

  AWAIT_READY(disconnected);
}
{code}

The {{Http}} class refers to the one used in the tests:
