From a05ab36bb54baa8b17a2bc91cb1e790e62f242fe Mon Sep 17 00:00:00 2001 From: Alan Conway Date: Fri, 31 Jul 2009 18:40:26 +0000 Subject: Fix race condition in cluster error handling. If different errors occured almost simultaneously on two different nodes in a cluster, there was a race condition that could cause the cluster to hang. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk@799687 13f79535-47bb-0310-9956-ffa450edef68 --- qpid/cpp/src/tests/PartialFailure.cpp | 27 ++++++++++++++++++++++++--- 1 file changed, 24 insertions(+), 3 deletions(-) (limited to 'qpid/cpp/src/tests/PartialFailure.cpp') diff --git a/qpid/cpp/src/tests/PartialFailure.cpp b/qpid/cpp/src/tests/PartialFailure.cpp index 7169e53a16..f77a1401f8 100644 --- a/qpid/cpp/src/tests/PartialFailure.cpp +++ b/qpid/cpp/src/tests/PartialFailure.cpp @@ -82,10 +82,31 @@ void queueAndSub(Client& c) { c.subs.subscribe(c.lq, c.name); } +// Handle near-simultaneous errors +QPID_AUTO_TEST_CASE(testCoincidentErrors) { + ClusterFixture cluster(2, updateArgs, -1); + Client c0(cluster[0], "c0"); + Client c1(cluster[1], "c1"); + + c0.session.queueDeclare("q", durable=true); + { + ScopedSuppressLogging allQuiet; + async(c0.session).messageTransfer(content=pMessage("TEST_STORE_DO: s0[exception]", "q")); + async(c1.session).messageTransfer(content=pMessage("TEST_STORE_DO: s1[exception]", "q")); + + int alive=0; + try { Client c00(cluster[0], "c00"); ++alive; } catch (...) {} + try { Client c11(cluster[1], "c11"); ++alive; } catch (...) {} + + BOOST_CHECK_EQUAL(alive, 1); + } +} + +#if 0 // FIXME aconway 2009-07-30: // Verify normal cluster-wide errors.
