Absorbs 106 upstream commits. Seven files conflicted; the substantive one
was upstream's new JSON ConfigSerializer (PR #2982), which replaces the
binary /com_prefs layout with /prefs.json and makes NodePrefs a
ConfigSerializer subclass.
Prefs migration
- Adopt upstream's ConfigSerializer. writeCommonPrefsImage() and its
documented offsets (0-294) are deleted, along with the now-unreachable
saveCommonPrefsImageAtomically()/CommonPrefsFileStore atomic rename path.
- Load order is /prefs.json, then /com_prefs, then /node_prefs. Upstream
dropped the /node_prefs fallback; it is restored here so devices that
never advanced past that filename keep their config.
- Legacy files are never removed, so migration cannot destroy its own
source and a deferred or failed save simply retries next boot.
- /com_prefs is treated as a format migration only, not an "upgrade", so
it does not trip the bridge.source tx->rx flip on existing nodes.
- The MQTTPrefsAtomicStore legacy gate is retained: the observer tail
recovered from an old-format file still commits to /mqtt_prefs before
/prefs.json is written.
- MQTTPrefs and /mqtt_prefs are untouched; savePrefs keeps its save_mqtt
parameter and now returns upstream's bool.
Fixes to upstream code
- RadioPrefs::structure() bound both "rxgain" and "fem_rxgain" to
rx_boosted_gain, so radio_fem_rxgain was never persisted. Bound to the
correct field.
- discovery_mod_timestamp was dropped from structure(); it gates
'since'-filtered DISCOVER replies and is set on every config change, so
losing it would silently stop discovery responses after a reboot. Added
as "disc_mod".
Merge artifacts repaired
- Restored bblanchon/ArduinoJson to the native test env; a clean but wrong
auto-merge at the lib_deps block boundary dropped it and broke all 19
host test suites.
- Migrated the fork's WebConfig UITask screens off the removed
DisplayDriver::Color enum to upstream's UIColor element types.
- Removed duplicate getCADEnabled() definitions in companion MyMesh.cpp
and simple_sensor SensorMesh.cpp that both sides had added.
- Dropped memset(&_prefs, 0, ...) in the four example meshes; NodePrefs now
has a vtable. guard gains an initializer that memset used to provide.
Other resolutions
- simple_room_server keeps both the fork's discover.* commands and
upstream's new room.post.
- docs/payloads.md taken from upstream, undoing content earlier merges had
reverted (Control data section, split login tables).
Verified: 273/273 host tests pass across native and native_kiss_modem;
Heltec v3 repeater, repeater_observer_mqtt, room_server_observer_mqtt,
sensor, and companion_radio_ble all build clean.
A merge conflict resolution collapsed the `// node name` comment and its
`_display->setCursor(0, 0)` call onto a single line, which commented out
the cursor reset. The node name then rendered at whatever cursor position
was left over from the previous frame (the end of the IP: line), so it
trailed the IP address and wrapped onto the next line instead of appearing
at the top of the home screen.
Split the comment and setCursor back onto separate lines so the name is
drawn at (0, 0) again.
First upstream merge since the 2026-06-06 base (191 upstream commits). 14 files
conflicted; resolutions below.
Fleet-critical check (Constraint 1): upstream reordered NodePrefs members
(rx_boosted_gain / path_hash_mode moved to the struct tail) but did NOT change
/com_prefs. Persistence is written field-by-field at explicit offsets, so member
order is in-memory only. Verified the fork's writeCommonPrefsImage() is
byte-identical to upstream's inline writer at every offset (79 pad, 121, 122,
290-294). No migration needed.
Resolutions:
- CommonCLI.h: kept the fork's NodePrefs (superset) and adopted upstream's
setRxBoostedGain(bool)->bool signature change, which CommonCLI.cpp now uses to
report unsupported. Corrected a stale comment claiming rx_boosted_gain lives at
offset 79 (it is a pad; the field is at 290).
- CommonCLI.cpp: kept the fork's legacy /com_prefs migration and the extracted
writeCommonPrefsImage() call.
- UITask.cpp: three-way merge - upstream's drawTextCentered + powering-off
screen, plus the fork's WITH_WEBCONFIG portal/reboot screens.
- ESP32Board.cpp, MeshCore.h, platformio.ini: kept both sides (fork OTA additions
alongside upstream powerOff/enterDeepSleep and Packet.cpp).
- MicroNMEALocationProvider.h: took upstream's claim/release and added the
_claims member they depend on.
- MyMesh.cpp/.h (repeater + room server): kept the fork's superset defaults.
- Removed duplicate declarations auto-merge produced: RadioLibWrapper::_cad_enabled
and MyMesh::getCADEnabled().
Verification: native suite 15/15 (incl. upstream's new test_mesh_tables), both
MQTT smoke builds green, ArduinoJson pin check passes. Hardware validation next.
- Added getTextWidth method to DisplayDriver interface
- Implemented getTextWidth in all display classes
- Updated examples to use getTextWidth directly
