RHBA-2011:1670 - Bug Fix Advisory

Topic

Updated qpid-cpp packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

The qpid-cpp packages provide a message broker daemon that receives, stores, and
routes messages using the open AMQP (Advanced Message Queuing Protocol)
messaging protocol along with runtime libraries for AMQP client applications
developed using Qpid C++. Clients exchange messages with an AMQP message broker
using the AMQP protocol.

The qpid-cpp package has been upgraded to upstream version 0.12, which provides
numerous bug fixes and enhancements over the previous version. (BZ#706949)

This update fixes the following bugs:

• In the previous version of Red Hat Enterprise Linux, when an attempt to

convert a negative value of a Variant Qpid type into an unsigned short type
value was made, an exception was issued. In Red Hat Enterprise Linux 6, no
exception was issued and the value was converted, e.g. "-5" became "65531". This
bug has been fixed and the exception is now properly issued in the described
scenario. (BZ#695777)

• Previously, non-static "isManagementMessage" class member was sometimes passed

an uninitialized value. This bug has been fixed and only initialized values are
now passed in the described scenario. (BZ#735058)

• The XML-Exchange library (as part of the qpid-cpp-server-xml package) is only

available on x86, Intel 64, and AMD64 architectures. Previously, this caused
additional dependencies on the xqilla and xerces-c packages to be added to the
qpid-cpp RPM package. However, functionality of these two packages is not needed
for the Matahari agent infrastructure. This update removes the dependency on
these two packages for the PowerPC and IBM System z architectures. (BZ#740912)

This update adds the following enhancement:

• Previously, qpid-cpp was only built for x86, Intel 64, and AMD64

architectures. This update adds support, which is needed to provide the Matahari
agent infrastructure on PowerPC and IBM System z architectures. (BZ#663461)

Users of qpid-cpp are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
