All the necessary "glue" logic to convert ROS Data to a form that the
DDS/RTPS back-end can use is implemented in packages.
The ROS Node discovery information is statically generated in packages
(similar to the RTPS Participant Data), and a special dds writer is
implemented (ros_static_discovery_writer) that has this static data as
its only payload sample.
Some definitions are moved out of rtps_config_package to prevent
circular package dependency.
The inline-QoS of PDP Packets is parsed, and Participants/Endpoints can
be unmatched by Unregister/Dispose Status Info Updates.
Test 1,2,3 was extended to test this functionality.
NOTE: PID_KEY_HASH is a requirement (at least for unmatching Endpoints),
as serialized key payloads are unsupported.
The REMOVE_WRITER DDS Operation of DDS Reader now generates Samples if
the Instance State changes.
Updated testbench.
Added checks for DATA_AVAILABLE communication status.
Test Sample Rejected Status Handling.
Test GET_SAMPLE_REJECTED_STATUS DDS Operation.
Extend Sample Rejected Status Kind by REJECTED_BY_PAYLOAD_MEMORY_LIMIT
The Memory Control Process is made more generic (with less specialised
code), to allow the main process more control. I.e. all Memory Frame
Fields are individually addressable (during GET and UPDATE).
The RAM instance is hidden behind a Memory Controller with Flow Control
Signals, allowing easy future integration to different Memory Interfaces
(e.g. AXI Lite).
Finalized DDS Reader interface. Implemented read/take,
read_next_sample/take_next_sample, read_instance/take_instance,
read_next_instance/take_next_instance operations.
Instance Get operations were made generic to allow returning 2 variants
of instance data.
Redefined Sample Memory Format. The design decision was made to handle
most (if not all) of the DDS QOS inside the History Cache, which allows
storing needed information in a more efiicient way.
A (dual port) Instance Memory was added into the HC, to support the QOS
operations.
This commit only implements the A side processes for the READER case.
RESOURCE_LIMITS_QOS, TIME_BASED_FILTER_QOS, and HISTORY_QOS are handled.
The inter-entity communication was changed to allow the HC to mark
parsed changes as rejected, and allow future re-transmission (in the
case of Reliable communication).
