fix(moq-net): map stream reset codes to the negotiated moq-transport draft - #3450
Conversation
…draft Every RESET_STREAM and STOP_SENDING on an IETF session went out with a moq-lite code, and came back decoded against the moq-lite table, whichever draft was negotiated. The registries overlap but do not match: draft-18 took 0x4 for GOING_AWAY from UNKNOWN_OBJECT_STATUS, TOO_FAR_BEHIND arrived in draft-17 and MALFORMED_TRACK in draft-16, and moq-lite's provisional 32-63 placeholders and 64+ application codes have no home in this registry at all. `ietf::error` is now the per-draft mapping in both directions, and the new `coding::StreamCodes` trait picks a stream's registry from the version its Reader/Writer already carries, so encoding and decoding cannot drift apart.

Raw payload writes bypassed the version-aware stream code conversion, so draft-17 STOP_SENDING 0x4 became GoingAway. Route them through the shared mapping and add a regression that fails before the fix. Clarify the separate request/reset registries and the protocol bridging rule.

- Around line 5-8: Revise the cache-miss goal in the moq-hls documentation so
the 404 requirement is conditional on the request-error decision preserving the
cache-miss classification on the wire; explicitly allow 500 when an IETF stream
reset cannot identify a cache miss, while retaining 500 for genuine failures.

Final Codex and CodeRabbit reviews completed on a35b120 without actionable findings. Keeping the HLS follow-up quest: it directly records the downstream classification problem exposed by these reset registries, as required by the repository follow-up policy. The generic docstring percentage does not identify a missing exported API doc; the mapping remains private and test helpers do not need API documentation. (written by GPT-6) |

Closes #3001.
Summary
0x4stays opaque instead of becomingGoingAwayduring a payload write.dev, clarify protocol bridging in the moq-lite draft, and record the clarification in its changelog.Missing content and reset codes
IETF request errors and stream resets have separate registries. A missing-content request should use the negotiated draft's
TRACK_DOES_NOT_EXIST/DOES_NOT_EXISTresponse. This PR does not change request responses: the existing literal404/500/400bug remains tracked by #3359 andquest/m0/ietf-error-codes.md.The stream-reset registry has no not-found or unroutable code. If such a condition reaches the reset fallback, it becomes
INTERNAL_ERROR; copying a request code into a reset would give it the wrong meaning. Other moq-lite-only provisional and application codes also fall back toINTERNAL_ERROR. moq-lite behavior is unchanged.Public API changes
None. The new mapping and trait are internal.
