55. Release LBM 3.3.6 / UME 2.0.4 - August 2008

• Known Issue: When using Event Queues with the Java API on Mac OS X kernel 9.4, core dumps have occurred. Mac OS X kernel versions prior to 9.4 have not produced this behavior. 29West is investigating this issue.

• Added LBMMessage class source and topic string caching to improve memory utilization dynamics (.NET and Java).

• Added new extended Hot Failover send capability in order to receive sequence number information to C, .NET, and Java APIs.

• Fixed memory corruption problem related to the use of select file descriptor management when registering a large number of file descriptors at the same time.

• Simplified LBMMessage creation within the Java API layer to avoid holding a reference to a C layer message for certain message types (e.g., requests).

• Fixed Java API access violation exception that appeared when performing a send using an LBMSourceSendExInfo object without setting the client object information.

• Fixed segfault caused by using lbmsdm_msg_clear().

• Fixed lbm_fd_cancel processing of file descriptors managed by epoll to avoid fatal assertion.

• Implemented .NET string caching.

• Implemented .NET data marshalling performance enhancements.

• Added error messages to lbmrd that indicate certain configuration file errors.

• The .NET API now allows the reuse of LBMSourceSendExInfo.

• Cleaned-up the Microsoft® Windows® build to ensure that the lbm.dll has dependencies on only one Microsoft runtime DLL to avoid problems caused by attempting to use different memory heaps.

• Made the maximum datagram size configurable. See context transport_datagram_max_size.

• Fixed Gateway fatal assertion ([Source->topic->source!=NULL] at line 769 in ../../../../src/lbmgwd/lbmgwod.c) resulting from an attempt to use the outbound side before it is completely initialized.

• Prevent premature garbage collection of LBMTimer .NET objects.

• Fixed problem causing sources to advertise topics in response to a non-matching wildcard query.

• Fixed condition causing a fatal assertion ([epoll_err==0] at line 1494 in ../../../../src/lib/lbm/lbmfds.c) when a source is deleted on a non-context thread.

• Fixed Java response support for topicless request messages.

• Made the construction of SDM (Self Describing Messaging) name tree optional to allow better performance.

• Fixed SDM deserialization of nested messages.

• Fixed .NET API structure alignment problem during UME receiver registration that sometimes caused an ArgumentOutOfRangeException.

• Receiver registrations are now ignored at the store until a topic resolution advertisement has been received from the corresponding source. This avoids a window that causes the receiver to request invalid retransmissions from the store.

• Fixed receiver's incorrect handling of the retransmission request target for round-robin store failover that manifests itself when a store fails during recovery of that receiver.
