[jira] Resolved: (DIRMINA-261) ioSession.close().join() when
SO_LINGERING set
[ https://issues.apache.org/jira/browse/DIRMINA-261?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Trustin Lee resolved DIRMINA-261.
---------------------------------
Resolution: Won't Fix
Marking as 'won't fix' because there was no objection. I added JavaDoc comment to warn users enough though.

> Key: DIRMINA-261
> URL: https://issues.apache.org/jira/browse/DIRMINA-261
> Project: MINA
> Issue Type: Bug
> Affects Versions: 0.9.4, 0.9.5, 1.0.0
> Environment: FC5 + Sun JDK 1.5.0_07 (also with _08 and JDK 6 b2)
> CentOS 3.7 + Sun JDK 1.5.0_07
> SUSE 9.1 + Sun JDK 1.5.0_07
> Windows XP SP2 + Sun JDK 1.5.0_08
> Reporter: Frederic Soulier
> Assigned To: Trustin Lee
> Fix For: 1.0.2

>
> ioSession.close().join() with SO_LINGERING set behaves completely differently on Windows and Linux.
> On a linux machine (acting as the server) when a disconnection occurs (say you pull the plug on the client machine) and depending on the value set for the SO_LINGERING the whole server will block for as long as the value specified in the SO_LINGERING.
> As far as I can tell it gets stuck in the lock.wait() of the IoFuture because it's not ready.
> /**
> * Wait for the asynchronous operation to end.
> */
> public void join()
> {
> synchronized( lock )
> {
> while( !ready )
> {
> try
> {
> lock.wait();
> }
> catch( InterruptedException e )
> {
> }
> }
> }
> }
> Running the same server code on a Windows machine, it doesn't block.
