Python port of the firmware's WITH_MQTT_NEIGHBORS feature (MeshCore PR #35 plus
the aba571ed pacing rework). Each cycle refreshes the zero-hop neighbour table
with a node-discovery broadcast, asks every neighbour for its region scopes, and
publishes the assembled table to the MQTT neighbors topic.
- NeighborScopeHelper: client side of the anon-regions request (the server side
already existed in openhop_core). Queries are strictly serialized -- firing
them as a burst makes the responses collide, which is what the firmware fix
addressed. router.inject_packet resolves at the firmware's logTx/logTxFail
boundary, so the response deadline is armed only once the request is on air
and the firmware's QUEUED/PENDING state machine collapses into an await.
The response window is sized from radio parameters, mirroring
neighborDiscoverQueryTimeoutMs().
- NeighborsPublisher: owns the schedule, the immutable per-cycle snapshot, and
the payload. The snapshot merges live discovery responses over the stored
table because get_neighbors() serves a 60s cache that store_advert() does not
invalidate.
- packet_router: offer PAYLOAD_TYPE_RESPONSE to the scope helper before the
companion fan-out; it consumes only on an authenticated tag match.
- Per-broker `neighbors: true` opt-in (default off) plus a
mqtt_brokers.neighbors.enabled master switch; interval is 12-336h as in
firmware, rejected rather than clamped.
- `discover.scopes` mesh CLI command triggers one cycle immediately.
The whole zero-hop table is published including neighbours that did not answer
(timeout / send_failed), matching the firmware payload. No 10 KB cap: that
existed for a fixed PSRAM buffer.
- Added security settings in config.yaml.example for managing authenticated clients.
- Introduced ACL class for handling access control and client authentication in acl.py.
- Created LoginHelper class for processing login requests and managing authentication in login.py.
- Added IdentityManager class for managing multiple identities in identity_manager.py.
- Updated main.py to initialize IdentityManager and LoginHelper, and register identities.
- Added packet_router to process ANON_REQ login packets through the LoginHelper.
- Updated dependency for pymc_core to use the feat/valid-packets-checks branch.
- Removed neighbor tracking logic from RepeaterHandler and moved it to AdvertHelper.
- Introduced PacketPipeline for centralized packet processing, ensuring all packets flow through repeater logic.
- Created handler helpers: TraceHelper, DiscoveryHelper, and AdvertHelper for better modularity.
- Implemented asynchronous processing of advertisement packets and discovery requests.
- Enhanced logging for better traceability and debugging.
- Cleaned up unused code and improved overall structure for maintainability.
