RHBA-2011:1671 - Bug Fix Advisory

Topic

Updated qpid-qmf packages that fix a bug and add various enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The qpid-qmf package provides an extensible management framework layered on Qpid
messaging.

• The qpid-qmf package has been upgraded to upstream version 0.12, which

provides a number of enhancements over the previous version. (BZ#706990)

This update fixes the following bug:

• Prior to this update, when "RequestContext._complete" was invoked, it would

clear the Agent's context, but not the Agent's sequence manager. Consequently
qmf console objects caused memory leaks. With this update the code has been
corrected and the memory leak of object instances in the Python console no
longer occurs. (BZ#743657)

This update adds the following enhancement:

• The qmfv2 utility did not provide a way to determine via a pollable file

descriptor if a new event was available. Consequently more processor intensive
methods were used. With this update a new, optional, feature has been added,
"qmf_fd". It is a file descriptor that is readable if, and only if, there is at
least one qmf event to be processed. (BZ#699499)

Users are advised to upgrade to these updated qpid-qmf packages, which fix this
bug and adds this enhancement.
