Updated packages that resolve various issues are now available for Red HatEnterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 6.

Red Hat Enterprise Linux OpenStack Platform provides the facilities forbuilding a private or public infrastructure-as-a-service (IaaS) cloudrunning on commonly available physical hardware.Changes to the ceph component:* In the previous version, launching of nova instances resulted in nova-computeto crash with a segmentation fault in certain cases when using Ceph RBD backend. This was due to the incorrect clean up in librbd1 packages. This has beenfixed in this release, and nova-compute now operates correctly with Ceph RBDback end. (BZ#1182608)Changes to the python-novaclient component:* With this enhancement, a new command ‘service-delete’ has been added to thenova client to allow disabling services through the nova CLI as opposed tomanually editing the nova-services table. (BZ#1206644)Changes to the python-requests component:* In the previous version, python-requests had issues including incorrect HTTPheaders’ generation, causing errors with python-swiftclient. This was due topython-requests having an incorrect implementation of a case insensitivemapping. With this release, case insensitive dictionary (CaseInsensitiveDict)has been updated which has fixed all issues with python-swiftclient.(BZ#1176181)Changes to the python-sqlalchemy component:* Previously, an improvement to the connection pool such that new connectionscould be made concurrently, made it so that the ‘init on first connect’ routineof a SQLAlchemy dialect would not have been completed if concurrent routinesproceeded at the same time. As a result, when a SQLAlchemy engine was firstused, operations which relied on the state acquired during initial startup couldfail, as this information would not have been completed.To resolve this issue, with this update, ‘mutexing’ was added to the eventsystem which handles the initial dialect startup phase, so that connectionattempts are again serialized, but only when the engine first starts up.(BZ#1198773)* Previously, the MySQL-Python DBAPI was observed under some circumstances usingthe ProgrammingError exception class to report on the ‘command out of sync’errors, which is considered to be the case where a connection need to be thrownaway; the SQLAlchemy dialect only expected this error to be emitted within theOperationalError class. As a result, in some cases a MySQL-Python connectionthat became corrupt would not signal to the SQLAlchemy engine that the pool ofconnections should be disposed, leading the engine not being able to proceedwith new operations.With this update, the error handling scheme of the MySQL-Python dialect ismodified to expect either the OperationalError or ProgrammingError exceptionclass when testing for this particular class of error. As a result, theSQLAlchemy engine/connection pool now correctly disposes off its connectionswhen a MySQL-Python ProgrammingError delivers the ‘command out of sync’ errorcode. (BZ#1198774)
