Attach packet drivers to initially empty ETCP connections. Share BLE neighbor
tracking and group fallback between desktop and Android in cgathui_common.
Deliver join links through a dedicated Write/Indicate characteristic with
independent fragmentation queues, application acknowledgements, deduplication
and bounded retries. Merge LAN/BLE discovery and add a separate Bluetooth
invitation reception setting to both clients.
Validation: 230 core tests, BLE transport/BlueZ/UI tests, ASAN/UBSAN,
Linux GUI and Android builds, and Windows backend cross-compilation.
Physical Android/Linux invitation exchange passed with either GATT initiator.
The Android-initiated run also verified all 32 ETCP packets of 1500 bytes;
the desktop-initiated load run reached 7/32 within its 45-second time limit.
Integrate shared C transport with desktop and Android frontends, add radio probes and detailed Windows diagnostics, and fix GUI build dependencies and early configuration startup errors.
Add a settings button to open the current config in an external editor. Wait for core, UTUN and chat startup before reporting readiness; verify startup failures and restarts. Include Wintun DLL and license notices in Windows builds and installers.
Все ETCP_ID_*/ETCP_RT_ID_* сведены в etcp_api.h (единственное место
определения) с реестром и предупреждением про коллизии в пределах одного
пространства имён. Убраны локальные define из topo_group.h,
topo_group_invite.h, db_sync.h, chat_sync.h, chat_join.h; хардкод 0x31 в
member_sync.c заменён на ETCP_RT_ID_MEMBER_SYNC.
Коллизия: chatgui-десктоп биндил мёртвый ETCP_RT_ID_CHAT 0x11 поверх
ETCP_RT_ID_CONN_MGR 0x11 — затирался conn_mgr_router_recv_handler, из-за
чего INDIRECT-обмен conn_mgr не работал и голос звонка не устанавливался.
Удалён мёртвый код recvCallback/messageReceived/send в utun_node.{cpp,h}.
- Добавлен device_type (1 байт, CLIENT_TYPE_*) в INIT_REQUEST и INIT_RESPONSE
- Добавлен keepalive_interval (2 байта) в INIT_RESPONSE
- STCP handshake расширен с 43 до 46 байт (device_type+keepalive)
- negotiate_keepalive(): оба desktop/server → min, иначе (есть mobile) → max
- keepalive_interval вынесен в UTUN_INSTANCE для использования в handshake
- stcp_client_connect() принимает device_type и keepalive_interval
- peer_device_type/peer_keepalive_interval передаются через stcp_link в ETCP_LINK
- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll
- stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close
- utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP),
add deferred drain in both Phase J and L
- stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39,
exchange ed25519_pubkey in both handshake directions
- etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in
etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb
- chat_sync.c: fix lk->conn NULL dereference for TCP links
- test_stcp.c: update stcp_server_create/stcp_client_connect callsites
- tools/chat_tcp_test: change transport udp→tcp
- stcp_server_create: support AF_INET and AF_INET6 V6ONLY=1 (no dual-stack)
- Add listen_family to stcp_link_config
- init_sockets: return error (not partial) on any bind failure
- add chat_core_sync_my_addresses() call at chatgui startup
- collect_my_addrs: add proto byte (1=UDP, 2=TCP) to binary format
- chat_sync.c JOIN/WELCOME/PEER_UPSERT: read proto byte, write protocol column
- member_sync.c: read proto byte, dynamic protocol bind
- topo_node.c: debug logs for nodeinfo changed detection
- node_config.cpp: type=public for all servers
- Создан src/chat/ с chat_event.h/c — система нотификаций
- Перенесены chat_core, chat_msg, chat_channel, chat_profile, chat_status
- Перенесены chat_sync, member_sync, merkle_sync, db_sync
- gui_bridge_post() заменён на chat_event_post() с возможностью регистрации обработчика
- chat_event_set_handler() — chatgui регистрирует мост в gui_bridge
- Без обработчика: события логируются через DEBUG_DEBUG + log_dump
- chat интегрирован в utun_instance.c (при db_path в конфиге)
- Обновлены include-пути, Makefile.am, CMakeLists.txt
- Из chatgui удалены старые transport/ файлы, обновлён utun_node.cpp
SIGINT on Linux can be delivered to any thread (not just worker).
signal_handler uses g_currentNode->requestStop(); with thread_local,
g_currentNode was nullptr in non-worker threads — Ctrl-C did nothing.
Removing thread_local fixes signal delivery: g_currentNode is set once
before signal handler is registered, pointer read is atomic on x86/x64.
Signal handler via g_shutdown + uasync_wakeup ensures clean uasync poll exit.
updateReadPosition() now saves both lastReadMsgId and lastPosMsgId on every
scroll stop (300ms debounce), not just when read position changes.
connect(stopped, quit) triggers graceful Qt shutdown after uasync cleanup.
