chenta lee updated QPID-1766:
-----------------------------
Attachment: selector.patch
Thank you Gordan, I fixed the locking bug.
And Carl mention me that I still use popAnddequeue in Queue::consumNextMessage.
I also fixed this.
I found out that the field "Message& msg" in Queue::seek function is
unnecessary. Because I already pass an iterator into it. So I did some
modification.
However, I am curious about why do we need another message variable in
popAndDequeue. Can't we just dequeue it first and then pop the message?
Because I am not sure if store->dequeue will modify the queue so I did the same
way in earseAndDequeue.
