From d738d179e4c040e62438516bc0992736d00b902f Mon Sep 17 00:00:00 2001 From: Alan Conway Date: Fri, 4 Jul 2008 19:07:33 +0000 Subject: 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. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@674107 13f79535-47bb-0310-9956-ffa450edef68 --- cpp/src/qpid/broker/SignalHandler.cpp | 51 +++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 cpp/src/qpid/broker/SignalHandler.cpp (limited to 'cpp/src/qpid/broker/SignalHandler.cpp') diff --git a/cpp/src/qpid/broker/SignalHandler.cpp b/cpp/src/qpid/broker/SignalHandler.cpp new file mode 100644 index 0000000000..c6d7b10218 --- /dev/null +++ b/cpp/src/qpid/broker/SignalHandler.cpp @@ -0,0 +1,51 @@ +/* + * + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
