--------------------------------------
Summary: Provide a means for libprocess users to exit while
ensuring messages are flushed.
Key: MESOS-4111
URL: https://issues.apache.org/jira/browse/MESOS-4111
Project: Mesos
Issue Type: Bug
Components: libprocess
Reporter: Benjamin Mahler
Priority: Minor
Currently after a {{send}} there is no way to ensure that the message is
flushed on the socket before terminating. We work around this by inserting
{{os::sleep}} calls (see MESOS-243, MESOS-4106).
There are a number of approaches to this:
(1) Return a Future from send that notifies when the message is flushed from
the system.
(2) Call process::finalize before exiting. This would require that
process::finalize flushes all of the outstanding data on any active sockets,
which may block.
Regardless of the approach, there needs to be a timer if we want to guarantee
termination.
