Templates with the pre-defined code hull for the reader_wrapper,
writer_wrapper, and key_holder were created.
A "cookbook" of how to expand this TEMPLATES to create type specific IDL
conversions was also added.
The "code generation" is kept general to allow a code generator to
automatically produce this wrappers in the future.
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.
Until now the ACKNACK Response of the RTPS Builtin Endpoint had an empty
Bitmap, effectively ACKing SNs, but never NACKing any (i.e. not
requesting any).
Similar to the RTPS Endpoints we request the next 32 SNs on every
ACKNACK Response.
The ParticipantMessageData SN Handling was also implemented.
Backport Memory Controller and Memory FSM from RTPS/DDS Endpoints to
RTPS Builtin Endpoint.
The Memory is now using a single linked list and the FSM uses Frame Field
Flags.
The main FSM uses check_time to initiate stale checks, and the stale
checks are done in the main FSM.
Testbench was modified to accomodate the changes (Previous L0 Test4 was
removed and integrated in L0 Test 1).
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 the DDS READ, TAKE, READ_NEXT_SAMPLE, TAKE_NEXT_SAMPLE,
READ_INSTANCE, TAKE_INSTANCE, READ_NEXT_INSTANCE, TAKE_NEXT_INSTANCE
Operations.
Backport fixes to previous testbenches.
Change handling of DISPOSE Samples of unknown Instances.
Test RTPS GET_MIN_SN, GET_MAX_SN, GET_CACHE_CHANGE, REMOVE_CACHE_CHANGE,
ACK_CACHE_CHANGE, and NACK_CACHE_CHANGE Operations.
Test DDS Register, Unregister, Write, Dispose, and Lookup Instance
Operations.
The instantiation of the KEY related entities is moved outside the DDS
Endpoints (Currently only changed in DDS Writer). Define new KEY_HOLDER
entity that is responsible for all Key related type-specific code.
Fix syntax of DDS Writer, and misc code refactoring.
Tests are added for different Generics Settings (Durability,
Reliability, Keyed Topic).
Test 2 of RTPS Reader (User Tarffic Handling) is extended with a few
extra test cases.
Since the payload can only be padded until the next 4-byte aligned
address, we needed a way to read out only the actual payload in case the
payload was not aligned in the last payload slot (did not go until the
end of the payload slot). This is now handled by an additional bit flag
in the Sample Status Info which denotes if the payload is aligned. In
the case the payload is unaligned, the last address of the last payload
slot contains the offset of the actual payload end.
This commit also adds MEMORY RESET states for the Sample, payload, and
instance Memory.
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.
It was decided to connect the DDS Endpoint directly to the RTPS
Endpoint. The history_cache Entity will be converted to a generic
History Cache acording to the RTPS Specification.
Because of consistency requirements the implementation was changed to a
single process/single port RAM design.
This should fully (blindly) implement the RTPS Reader side of the DDS
Entity.
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).
While previously we sent the EntityID before the GUID Prefix (for some
reason), we changed swaped the order to allow easier decoding (by having
uniform format for all inputs)
