- Replace db_sync_stub.c with real src/db_sync.c in libutun
- Remove message sync protocol from chat_sync (INIT_SYNC/INIT_RESP/SEND_DATA/PUSH/ACK_PUSH/SYNC_DONE)
- Keep chat_sync auxiliary: join protocol, peer management, auto-connect
- Remove chat_core_insert_record, cursor_*, mark_sent/ttl_delete stubs
- chat_core on_db_sync_insert now only does SQLite INSERT + GUI notify
- Move db_sync_init() from instance_init_common to utun_instance_init for config override timing
- Force db_sync_enabled=1 in utun_node.cpp
- db_sync handles all P2P message sync via service 0x20
- chat_core_connect_auto: direct ETCP connect from SQLite (no BGP)
- auto_connect: parallel connect to peers with 3s timeout, retry 10s
- RTT saved to node_addresses on disconnect
- vertical status bar + circle badge with online count per channel
- ChannelListView prevents deselection
Remove secondary level filtering in debug_output(). Now the only filter
is debug_should_output() (per-category + global fallback). Output goes
to file (if file_output set) or console (if console_enabled), with no
additional level check.
Removed:
- debug_set_console_level(), debug_set_file_level()
- console_level, file_level fields from debug_config_t
- debug_set_level() no longer sets console_level
New category (id=25) replaces DEBUG_CATEGORY_DEBUG in chat_sync and
chat_core. This allows enabling only protocol-level logs (SEND/RECV,
timeouts, handshake) without the noise from DEBUG category.
Changes:
- debug_config.h: add CONNECTIVITY=25, COUNT→26
- debug_config.c: add 'connectivity' to g_debug_categories
- chat_sync.c: DEBUG→CONNECTIVITY in all protocol logs
- chat_core.c: DEBUG→CONNECTIVITY in connection/create logs
- utun_node.cpp: remove hardcoded DEBUG=TRACE (now config-driven)
- chatgui.cfg: connectivity=info in debug_categories
- debug_ui.h: remove NDEBUG guard so GUI_ERROR works in Release builds
- invite_link.h/cpp: add error field to InviteData with specific failure reason
- joindialog: show exact decode error in QLabel instead of generic message
- chat_sync: implement invite connect flow (CHANNEL_INFO_REQ/RESP, JOIN, WELCOME)
- topo_node_sqlite: node/address table init and lookup
- utun_node: getInviteAddresses fallback from ETCP sockets
- minor fixes in mainwindow, chat_core, gui_bridge
- Add CreateGroupDialog with group name input
- Generate X25519+Ed25519 keypairs, random uint64 channel_id,
Ed25519 signature, write to DB via uasync thread
- chat_core_create_channel(): create msg table, topo_node_sqlite_channel_put()
- GUI_EVT_CHANNEL_UPDATED notification to reload channel list
- Per-category debug config: debug_level= + debug_categories= in [gui]
- Unified logging via debug_config: all threads write to same file/console
- debug_enable_console(1) to mirror file output to stderr
- DEBUG_LEVEL_DISABLED=-1: truly disable category, NONE=0 fallback to global
- Fix uasync_post under epoll: process_posted_tasks was never called
- Fix MainWindow constructor parameter ordering (dbPath vs debugFile)
- debug_ui.h: append mode ('a' instead of 'w')
- UtunNode runs uTun instance in a dedicated std::thread
- no TUN, no msg_transport — direct etcp_route_send/recv calls
- Thread-safe cross-thread communication via Qt signals
- C callback (etcp_recv_fn) stores UtunNode* via thread_local
- etcp_router_bind on service ID 0x11 for chat messages
- uasync_poll(100ms) loop runs until stop() called
