Summary: 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
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}
