----------------------------------
Shepherd: Vinod Kone
Sprint: Mesosphere Sprint 47
> IOSwitchboard doesn't properly flush data on ATTACH_CONTAINER_OUTPUT
> --------------------------------------------------------------------
>
> Key: MESOS-6746
> URL: https://issues.apache.org/jira/browse/MESOS-6746
> Project: Mesos
> Issue Type: Bug
> Reporter: Kevin Klues
> Assignee: Anand Mazumdar
> Labels: debugging, mesosphere
> Fix For: 1.2.0
>
>
> Currently we are doing a close on the write end of all connection pipes when
> we exit the switchboard, but we don't wait until the read is flushed before
> exiting. This can cause some data to get dropped since the process may exit
> before the reader is flushed. The current code is:
> {noformat}
> void IOSwitchboardServerProcess::finalize()
> {
> foreach (HttpConnection& connection, outputConnections) {
> connection.close();
> }
>
> if (failure.isSome()) {
> promise.fail(failure->message);
> } else {
> promise.set(Nothing());
> }
> }
> {noformat}
> We should change it to:
> {noformat}
> void IOSwitchboardServerProcess::finalize()
> {
> foreach (HttpConnection& connection, outputConnections) {
> connection.close();
> connection.closed().await();
> }
>
> if (failure.isSome()) {
> promise.fail(failure->message);
> } else {
> promise.set(Nothing());
> }
> }
> {noformat}
