OrcaSonar's /mqtt WebSocket proxy writes each ~8 KiB TCP read as its own
WebSocket binary message, so an MQTT packet larger than one read (e.g. a
files.list reply) spans several messages, and several packets can arrive in
one. OrcaMqttConnection assumed exactly one packet per message, so packets
that spanned messages were dropped and the request timed out ("Load failed").
Keep a per-connection byte buffer and extract complete packets by their
remaining-length header, dispatching each. A malformed header (or a declared
size past a 16 MiB cap) drops the connection so the worker reconnects rather
than buffering forever.
Follow-up to the feature/OrcaSonar review. Scopes the new behavior to the
OrcaSonar agent, fixes several AMS-sync and lifecycle bugs, and makes the
MQTT tests run in CI. Non-OrcaSonar agents keep their existing behavior.
## Changes
Discovery
- Gate the background SSDP scan to a configured OrcaSonar machine instead of
running for every non-BBL profile; drive discovery on demand from the
machine-select popup and back off idle rounds from 5s to 60s.
- Add NSLocalNetworkUsageDescription and NSBonjourServices to both macOS
Info.plist templates.
AMS sync
- Resolve id-less printer-set trays by material type in get_ams_cobox_infos
and the sidebar badge loop, matching sync_ams_list, so combo arrays and
badges stay aligned.
- Keep a printer-set tray that resolved by type out of the "unknown or
incompatible filaments" dialog.
AMS device UI
- Gate the "Empty" tray classification, and the editable temperature fields,
to the OrcaSonar agent; Bambu keeps "?" and read-only presets.
- Validate AMS material temps on confirm: reject out-of-range values and
min > max before the command is sent.
Storage tab
- Bind the show/hide handler on the panel's ancestors (StoragePanel and
MonitorPanel) and unbind on destruction, so the Bambu file system stops
when the tab is left.
Transport
- Load /etc/ssl/cert.pem on macOS in add_platform_root_certificates, after
set_default_verify_paths.
- Release lifecycle_mutex before start()'s connect wait so stop() can cancel
the attempt and signal completion instead of stalling the UI thread.
Localization
- Add OrcaFilesPanel.cpp to list.txt and regenerate the catalogs.
## Tests
- Un-hide the loopback MockBroker integration tests (ephemeral port, no
network) so ctest registers and runs them.
- Mock broker tracks SUBSCRIBE/UNSUBSCRIBE and delivers push_report only to a
subscribed topic; the reconnect test asserts the re-SUBSCRIBE.
- Add bbl empty-tray cases, an AMS combo-alignment case, and unknowns
assertions to the AMS sync tests.
