REDHAWK Release Notes - 2.2.6

The effort in REDHAWK 2.2.6 focused on:

• Resolving an exception that occurred when calling theAllocationManager’s listAllocations method with no arguments.
• Adding developer documentation to explain how to enable JacORB for Java components.
• Fixing typos in component sample code comments.
• Implementing fixes to properly initialize the persona device logger.
• Changing _bindir to _libdir in the generated .spec file for generated C++ components.
• Adding a return code to cleanomni to indicate when one of the steps failed. In the event of an error, cleanomni still attempts each step of the cleanup process before exiting with a non-zero status.
• Modifying Device Manager behavior to no longer hang on shutdown when non-DCD devices/services remain registered.
• Resolving an issue with the DeviceManager exiting during device and service registrations due to unhandled exceptions.
• Updating the behavior of the GPP’s memory threshold monitoring to more accurately reflect real world usage. The available memory is calculated using MemAvailable, which provides the best estimate per the Linux kernel and does not include swap memory. The default value for the free memory threshold is now the lesser of 20% of total memory, or 6GB.
• Resolving a dead lock issue that occurred during the omniEvents check point operation.
• Preventing the file system from crashing when files are removed while list() is invoked.
• Resolving handling of process lifecycle by the GPP when process identifiers are reused on a busy system. Adding safeguard against the GPP terminating processes when the process identifier and process group identifier are not the same.
