Subject svn commit: r674107 - in /incubator/qpid/trunk/qpid/cpp/src: ./ qpid/ qpid/amqp_0_10/ qpid/broker/ qpid/cluster/ qpid/framing/ qpid/log/ qpid/sys/ qpid/sys/posix/ tests/
Date Fri, 04 Jul 2008 19:07:34 GMT
Author: aconway
Date: Fri Jul  4 12:07:33 2008
New Revision: 674107

URL: http://svn.apache.org/viewvc?rev=674107&view=rev
Log:
Cluster prototype: handles client-initiated commands (not dequeues)

Details
 - Cluster.cpp: serializes all frames thru cluster (see below)
 - broker/ConnectionManager: Added handler chain in front of Connection::received.
 - sys::Fork and ForkWithMessage - abstractions for forking with posix impl.
 - tests/ForkedBroker.h: test utility to fork a broker process. 
 - broker/SignalHandler: Encapsulated signal handling from qpidd.cpp
 - Various minor logging & error message improvements to aid debugging.

NB: current impl will not scale. It is functional working starting point so we
can start testing & profiling to find the right optimizations.
