Subject: Re: CloseFuture listener alternative to channel.waitFor()
Please open a JIRA issue at https://issues.apache.org/jira/browse/SSHD
and specify the scenario that would require such an API. Please note
that when you call Channel#close, the return value is a CloseFuture to
which one can add listeners. Also, the ClientChannel has a waitFor
method that can be used to wait for the CHANNEL_CLOSED event.
Furthermore, you can register a ChannelListener whose #channelClosed
method will be called. Given so many ways to receive asynchronous
information about a channel being closed, why expose the internal
CloseFuture ?

Subject: CloseFuture listener alternative to channel.waitFor()
I need non-blocking means to wait for client request to complete.
With sshd-core-1.1.0 and reflection I can get to gracefulFuture field
of AbstractChannel and register a listener:
...
s_closeFutureField =
AbstractChannel.class.getDeclaredField( "gracefulFuture" );
s_closeFutureField.setAccessible( true );
...
timeout = commandEndTime - System.currentTimeMillis();
DefaultCloseFuture closeFuture;
try
{
closeFuture = (DefaultCloseFuture)
s_closeFutureField.get( channel );
}
catch ( IllegalAccessException e )
{
throw new RuntimeException( e );
}
//CloseFuture closeFuture = channel.getCloseFuture();
CloseListener closeListener = new CloseListener( workItem,
sc, channel, out );
AlarmHandler alarmHandler = new AlarmHandler(
closeListener );
Alarm alarm = getContext().getAlarmFactory().getAlarm(
alarmHandler, timeout );
closeListener.setAlarm( alarm );
closeFuture.addListener( closeListener );
sc = null;
return workItem.makeSuspend( "Waiting..." );
Could getCloseFuture() method be added to AbstractChannel?
Thanks,
Mike
