Hi! I use python-qpid and I have faced with a few bugs in it: * If you open a few connections, and one of them breaks (for example, due to a network error), another connections can be locked for time, which is equal to network timeout of the broken connection. This happens due to working with sockets in blocking mode and due to using one Selector for all connections. * All connections could become locked forever due to races between Driver and Selector objects. Driver object removes itself from the Selector non-atomically and a situation when Driver is alredy closed, but the Selector refers to it could happen. In this case select() call in the Selector raise an exeption due to self._transport.fileno() call on Driver where self._transport is None. The selector doesn't handle errors on select(), so the selector's thread will be stopped due to unhandled Exception. * There is no checks on EINTR error on os.* calls.
As a temporary solution for me, I've written a patch, which fixes the errors: https://github.com/KonishchevDmitry/qpid/commit/9090f7f32f5746d00de6fc378ac4b2f4fa75b856 It would be good if you'd include this patch to a new version of Qpid. -- Dmitry Konishchev mailto:konishc...@gmail.com --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org
