Timothy Bish commented on AMQNET-154:
-------------------------------------
This looks to be a simple bug in the Dispatcher used by consumers, the close
method looks as follows:
{noformat}
public void Close()
{
lock (semaphore)
{
m_bClosed = true;
queue.Clear();
if(m_bAsyncDelivery)
{
messageReceivedEventHandle.Set();
}
}
}
{noformat}
I think the if statement there should be:
{noformat}
if(!m_bAsyncDelivery)
{
messageReceivedEventHandle.Set();
}
{noformat}
Since the async delivery case only needs to trigger an event when a message
arrives whereas the sync delivery case needs to trigger a wakeup on close for
any waiting consumers.
