I want to run it with the Ref app before changing the PR to ready for review. I'm trying to clear CI issues first. |

@timcanham why not update ComLogger to do this? e.g. if the ports are attached write data products rather than files? My concern is that with all the alternative implementations, we get feature drift. With a configurable switch we do not. |
After discussion, this component can be made much more simple because it does not take on the file I/O capabilities of ComLogger. Thus, a new component is warranted. |

[Documentation] must fix Requirement SVC-COMLOGGER-005 describes behavior the component does not implement.
ComLoggerDp.cpp never "adjusts to the smaller size": on dpGet failure or an oversized packet it drops the buffer, emits DpBufferError (declared severity warning high, not WARNING_LO) and increments m_numBuffersDropped/NumBuffersDropped; there is no DpBufferOverflow counter. Sections 3.6/3.7/3.10 and the UT table already describe the drop behavior, so the requirement row is the stale one.

[Design] suggestion Concur (design-fit view, same site): Requirement 005 describes behavior the implementation does not have: it says emit WARNING_LO, adjust to the smaller size, and bump a DpBufferOverflow counter. ComLoggerDp.cpp instead emits DpBufferError (WARNING_HI), drops the packet, and increments NumBuffersDropped; nothing resizes. Either the code should implement the shrink-and-continue design or the requirement should state the drop design actually built (below). If shrink-on-allocation-failure is the intent, that changes the container-sizing design and I'd want the owner to weigh in.

|
|
||
| The ComLoggerDp component logs `Fw::ComBuffer` buffers (e.g., framed telemetry, events, or command packets) to F Prime Data Product records. The component can be commanded to start recording data products, stop recording data product, or modify the priority of existing data products in progress. This component is meant to replace the `ComLogger` in deployments where data product management of `Fw::ComBuffers` is desired. |
There was a problem hiding this comment.
[Documentation] suggestion docs/reference/system-functional/communication.md ("Communication Logging" section and the SDD link list at the top) only lists ComLogger, which this PR positions ComLoggerDp as an alternative to. Add the new component there so the subsystem reference stays current, e.g.:
[ComLoggerDp](https://github.com/nasa/fprime/blob/devel/Svc/ComLoggerDp/docs/sdd.md) records outgoing data as data-product containers instead of files, for deployments that manage recorded telemetry through the data product catalog.(Anchored here because the reference page is not in the PR diff.)

There was a problem hiding this comment.
[Documentation] suggestion Dictionary-facing annotation is stale: UpdatePriority_cmdHandler always stores m_priority and emits PriorityUpdated, so when recording is off the new priority is applied to all future containers (as the SDD and the UpdatePriorityNotRecording UT state) - it is not a no-op.

There was a problem hiding this comment.
[Design] could fix Concur (design-fit view, same site): FPP says UpdatePriority has no effect when recording is off, but UpdatePriority_cmdHandler unconditionally stores m_priority and emits PriorityUpdated, and startRecordingInternal() then overwrites m_priority with the start command's own priority — so the stored value is dead when off. Pick one: make the handler a no-op (with a response) when !m_enabled, or fix the FPP/SDD text so the model matches the code.

[Test Quality] must fix testPriorityPreserved never asserts the priority it exists to check.
The test's stated purpose is that priority 15 (not the default 5) reaches the container, but it only asserts
ASSERT_PRODUCT_SEND_SIZE(1); it passes identically if m_priority is ignored. dpSend serializes the header
into the sent buffer, so the priority is observable from productSendHistory via Fw::DpContainer::deserializeHeader().

[Test Quality] suggestion UpdatePriority on an active container is only verified by its event, not by the container's priority.
The distinct behavior of this path is m_container.setPriority(m_priority) on the in-flight container; the

[Test Quality] suggestion Priority on the newly allocated container is claimed but not asserted.
ASSERT_PRODUCT_GET_SIZE(1) only shows a container was requested. The priority set in allocateAndSetupContainer

[Test Quality] suggestion ComDpStopped with numSent == 0 is never asserted anywhere in the suite.
Both stop tests assert ComDpStopped(0, 1) (partial container present). This is the only stop with an empty

[Test Quality] could fix The container-full retry and "packet too large" drop paths in serializePacketWithRetry are untested.
This test sends exactly FW_COM_BUFFER_MAX_SIZE bytes and asserts the nominal outcome, so the first
serializeRecord never fails. To reach the retry (partial dpSend + re-dpGet) and the
handleBufferDrop(dataSize) branch, have productGet_handler return a buffer smaller than dataSize
(e.g. a tester flag) and assert ASSERT_EVENTS_DpBufferError(0, dataSize) / NumBuffersDropped.

[Test Quality] could fix StartComDp while already recording with a partial container (flush-then-reconfigure) is untested.
startRecordingInternal sends the partial container and resets m_currentPacketCount when re-started; no test
starts, logs one packet, then starts again and asserts ASSERT_PRODUCT_SEND_SIZE(1) plus the new
ComDpStarted payload. The configure(true, ...) entry shares this helper and is likewise unexercised.

[Test Quality] could fix The U8 testData[...]; Fw::ComBuffer comBuf; comBuf.serializeFrom(...) block is repeated in 12 tests.
Factoring it into a helper (e.g. Fw::ComBuffer makeComBuffer(const U8* data, FwSizeType size) or
void sendComBuffers(U32 count, ...) that also does the invoke_to_comIn + doDispatch() loop) shrinks each
test to its assertions and keeps a future format change to one place.

[Maintainability] suggestion maint-misleading-comment: record buffer hard-codes sizeof(U32) while serializePacketWithRetry claims to "support user changing the constant type".
ComLoggerDp.cpp:195-197 sizes the record as sizeof(ComLoggerDpSentry) + dataSize, but this array is sized with a literal U32 and a "4 bytes" comment. A project that widens ComLoggerDpSentry (the stated supported case) gets an ExternalSerializeBuffer overflow → FW_ASSERT at runtime, with nothing at the declaration hinting at the coupling. Derive the size from the constant so both places move together.

SIZE_OF_ComBufferRecord_RECORD(FW_COM_BUFFER_MAX_SIZE + <sentry size>) appears here and again in allocateAndSetupContainer() (ComLoggerDp.cpp:176-177). If the record layout changes (e.g. a sequence field is added next to the sentry), a fix to one copy silently leaves the public sizing helper and the runtime dpGet request disagreeing. Name it once and use it from both sites.

[Maintainability] could fix maint-unclear-parameters: leading boolean flag makes configure call sites unreadable.
The UT already shows the shape: configure(false, 0, 0) — the reader cannot tell what false controls, and when it is false the other two arguments are silently ignored (ComLoggerDp.cpp:30-33). Two functions (enableRecording(packetsPerContainer, priority) / disableRecording()), or an enum in place of the bool, would make the topology initialization code self-describing and remove the ignored-argument trap.
| //! \param packetsPerContainer: Number of packets per container | ||

[Maintainability] could fix maint-inexplicit-return: bare bool for validation success; the configure() call site drops it silently.
configure() (ComLoggerDp.cpp:29) calls this and ignores the result, so a reader of configure cannot see that a zero packetsPerContainer leaves the component disabled with no event. Returning Fw::Success (the framework status enum used by dpGet in this same file) makes the discarded status visible at every call site and removes the true/false polarity guess.

[Maintainability] could fix maint-code-duplication: "send partial container, reset count" is hand-inlined at three sites alongside finalizeFullContainer().
The same dpSend(m_container) + m_currentPacketCount = 0 pair appears here, in startRecordingInternal() (L126-133) and in serializePacketWithRetry() (L218-222), while finalizeFullContainer() (L241-248) wraps the same two statements for the full case. Any future bookkeeping on container send (a containers-sent counter, a size telemetry write) must be added in four places; generalizing finalizeFullContainer() into a sendContainerIfNonEmpty() helper called from all four leaves one place to edit.

[Maintainability] suggestion maint-dead-code: developer-tooling flag left in the framework's root CMakeLists.txt.
CMAKE_EXPORT_COMPILE_COMMANDS is an IDE/clangd convenience unrelated to ComLoggerDp; committing it here turns it on for every framework build and every downstream project that configures through this file, and nothing in the PR explains why. Drop it (developers can pass -DCMAKE_EXPORT_COMPILE_COMMANDS=ON locally or via settings.ini).

[Maintainability] could fix maint-oversized-function: main() is ~460 lines mixing six responsibilities.
Argument parsing, mode validation, input-file discovery, dictionary auto-detection, the whole collection-mode pipeline (decode + sort + write two logs) and the batch/single processing loop are all inline, nested up to five levels inside one try. A fix to, say, the dictionary lookup cannot be tested without running the CLI, and the sys.exit(0) in the middle of the try (collection mode) is easy to miss when editing the loop below. Extract parse_args(), validate_mode(args), find_input_files(), load_dictionaries(), run_collection_mode(), run_decode_mode().

[Security] must fix packetsPerContainer is unbounded; large values reach a ground-reachable FW_ASSERT via U32 truncation in DpManager.
allocateAndSetupContainer requests N * SIZE_OF_ComBufferRecord_RECORD(1028) (~1034·N bytes). DpManager::getBuffer does static_cast<U32>(size) before calling BufferManager, so an operator-chosen N whose packet size wraps mod 2^32 to a value < DpContainer::MIN_PACKET_SIZE gets a valid tiny buffer, and DpContainer::setBuffer asserts (bufferSize >= MIN_PACKET_SIZE). Values that wrap to a size ≥ MIN_PACKET_SIZE but < one record instead take the retry path below and leak one BufferManager buffer per packet. Bound N so the container size always fits a U32 (needs #include <limits>); the StartRecordingFailed format string should say so too.

[Correctness] Concur — also in scope for functional correctness (correctness-arithmetic): the U32 * FwSizeType product is unbounded, and handleBufferDrop(static_cast<U32>(containerSize)) truncates the reported size in DpBufferError for the same large-N inputs.
There was a problem hiding this comment.
[Operational] Concur — also in scope for operational consequences: StartComDp returns OK for any N, then merely-large N (e.g. 10 000 → ~5.2 MB per dpGet) fails every allocation, so 100 % of com traffic is dropped while only the first DpBufferError is visible (throttle 1; DpManager's BufferAllocationFailed throttles at 10) and recovery needs a re-command; bound N against the largest BufferManager bin in the SDD as well.

[Security] must fix StartComDp(0) while a partial container is open leaks that container's buffer.
The validation-failure branch clears m_enabled without sending m_container. Once m_enabled is false, neither stopRecordingInternal nor a later successful start flushes it (both gate on m_enabled), and the next comIn allocates a fresh container over it, so the buffer is never returned to BufferManager. Repeating start(N) → 1 packet → start(0) from the ground exhausts the pool (ground-driven DDoS). configure(false) has the same gap at init time.

[Correctness] Concur — also in scope for functional correctness (correctness-resource-leak): with m_enabled cleared and m_currentPacketCount > 0 left set, stopRecordingInternal skips the send and the next successful start zeroes the count, so the held container is neither sent nor freed and the packets already recorded in it are lost.
There was a problem hiding this comment.
[Operational] Concur — also in scope for operational consequences: each start(N)→packet→start(0) cycle permanently removes one ComLoggerDpBuffSize(N) buffer from the shared BufferManager bin, so a bin of B buffers is exhausted after B cycles and every other data-product producer on that bin starts failing.

[Security] could fix general-vulnerability/resource-leak: an empty container that rejects the record is abandoned, not recycled.
When serializeRecord_ComBufferRecord fails with m_currentPacketCount == 0, the just-allocated container is dropped on the floor and allocateAndSetupContainer overwrites m_container, so its buffer is never returned to BufferManager. Today this is reachable only through the undersized-container case flagged above, but the retry path should never orphan a buffer it holds; sending the (empty) container recycles it. (best-effort fix; verify before applying)
| // Serialization failed - container is likely full | |
| // Send the current partial container if it has any packets | |

[Design] could fix Concur (design-fit view, same site): When the first record of a fresh container fails to serialize (m_currentPacketCount == 0), the container's buffer is neither sent nor returned before allocateAndSetupContainer() overwrites m_container, so that buffer leaks from the BufferManager pool. With current sizing this is only reachable if the manager hands back a valid buffer smaller than requested, but the retry design should still release or send the old container on every path.
There was a problem hiding this comment.
[Correctness] Concur — also in scope for functional correctness (correctness-resource-leak): both the empty container overwritten by the retry dpGet and the empty container left behind when the retry fails (next comIn re-allocates at m_currentPacketCount == 0) are never returned; unreachable with correct sizing today, but the path is dead-wrong if ever taken.
There was a problem hiding this comment.
[Operational] Concur — also in scope for operational consequences: in the undersized-container case both the first and the retry container are orphaned, i.e. 2 BufferManager buffers per com packet, exhausting a bin of B buffers after B/2 packets — seconds at typical event/telemetry rates.

[C++ Design] suggestion CPP-26 (cpp-style-guide-violation): configuration headers are included as config/<Name>.hpp so a project's CONFIGURATION_OVERRIDES can replace them; hard-coding default/config/ bypasses that, so ComLoggerDpSentry can never actually be overridden despite the header's comment. Also add ComLoggerDpCfg.hpp to the HEADERS list in default/config/CMakeLists.txt (only the .fpp is registered) so the header is copied into the config include path.

[C++ Design] could fix CPP-30 (cpp-magic-number-replacing-constant): the buffer is sized with sizeof(U32) while serializePacketWithRetry writes sizeof(ComLoggerDpSentry); if a project overrides the sentry type the FW_ASSERT on serializeFrom fires. Size it from the constant itself.

[Correctness] Concur — also in scope for functional correctness (correctness-boundary): ComLoggerDpBuffSize() and serializePacketWithRetry both size by sizeof(ComLoggerDpSentry); only this array uses sizeof(U32), so a wider sentry makes the serializeFrom FW_ASSERT fire on a max-size ComBuffer.

[Design] Human design adjudication required. This adds a new Svc component, two new Svc port types, and a new default/config surface while the tracking issue #1986 is still labeled Consideration Item (not CCB-approved). Design questions for the owner before deeper review: (a) each record is a U8 array with a hand-rolled 0xDEADBEEF sentry, duplicating the record-id/length framing Fw::DpContainer already provides and making the product undecodable from the dictionary (hence the ~1.5k-line decoder under Svc/ComLoggerDp/scripts/ and follow-up #5845) — would a Fw.ComBuffer-typed record be the intended F Prime way? (b) should ground-side decoding live in this repo at all, or in fprime-gds?

[Design] must fix ComLoggerDpCfg.hpp is included by its default/config/ path (here and in ComLoggerDp.cpp:9) and is not listed under HEADERS in default/config/CMakeLists.txt (only the .fpp was added). That bypasses the project config-override mechanism, so the SDD claim that ComLoggerDpSentry "can be overridden in deployment-specific configuration files" is not true. Register the header and include it via the config module like every other *Cfg.hpp:

[Operational] could fix ops-failure-path: a downlink burst that overruns this queue asserts the flight computer from a logging side-path.
Scenario: comIn uses the FPP default queue-full policy, and the generated comIn_handlerBase does FW_ASSERT(qStatus == OP_OK) on a full queue. Every com packet (each event/telemetry frame) is a queue message, so an event storm from a fault — exactly when this recorder is most wanted — can exceed the instance queue depth and reset the FSW, losing the partial container and all pending ComBuffers.
Consequence: with a queue depth of D, one burst of D+1 packets between two ComLoggerDp dispatches is sufficient; the burst window is the dispatch latency of this (typically low-priority) task under the highest-priority producer.
Operational judgment call: this matches Svc::ComLogger today. Smallest remedy: SDD guidance that the instance queue must be sized to the worst-case burst of the com stream (framer/ComQueue depth + event throttles), or opt into drop if the mission prefers counted loss over a reset.

[Operational] could fix ops-doc-reality: SDD omits the reset-loss window implied by packetsPerContainer.
A partial container lives only in the BufferManager RAM buffer until N packets arrive or StopComDp; there is no time-based flush (schedIn only emits telemetry). After a reset or power cycle, up to N-1 packets are lost — for the §5.7 example (N=200) that is the last 200 com packets, i.e. the last 200 s of a 1 Hz event/telemetry stream immediately preceding the anomaly, which is the data an operator most needs. Operators pick N from this section, so the tradeoff (fewer, larger DP files vs. loss window) should be stated here.

| This starts recording with 100 Com buffers per data product container at priority 5. | |
| > **WARNING:** Packets in a partially filled container are held in RAM until `packetsPerContainer` packets arrive or `StopComDp` is commanded; there is no time-based flush. A reset loses up to `packetsPerContainer - 1` packets. Choose `packetsPerContainer` from the acceptable loss window at the expected com rate (e.g. 1 Hz × 100 packets = 100 s), not only from the desired data-product file size. |

This adds a component that is an alternative to
Svc/ComLogger.ComLoggerDp will create and write data products withFw::ComBuffer` logging instead of raw files.Rationale
This fits more neatly with a data product centric data management scheme if a project wants recorded telemetry for later downlink using data product/catalog automation.
Testing/Review Recommendations
Unit tests can be run to verify logic.
