[jboss-jira] [JBoss JIRA] Commented: (JBREM-1189) Graceful connection close

[David Lloyd (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBREM-1189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12517341#action_12517341 ] 

David Lloyd commented on JBREM-1189:
------------------------------------

In order to ensure smooth operation of the test suite, I've added an "awaitClosed()/awaitClosedUninterruptibly()" method pair to coordinate clean shutdown.  Maybe all that's needed is one more method - requestClose(), something like that - on Connection which does the graceful shutdown?

Or maybe close() should be graceful by default with an additional closeImmediate() method.

I think the first might be better though.  Then the pattern would look something like this:

connection = do connect;
try {
    ... do work ...
    connection.requestClose();
    connection.awaitClosed();
} finally {
    // make sure it is shut down either way...
    safeClose(connection);
    // this might be needed as well:
    connection.awaitClosedUninterruptibly();
}

> Design a mechanism for graceful connection shutdown.  This could work in one of a few ways:
> 1. Refuse new clients, immediately close all clients, allow outstanding requests to finish
> 2. Refuse new clients, keep connection up until all clients are closed and all outstanding requests to finish
> #1 might be better - since requests have a finite lifespan but clients can hang around indifinitely.
