- Replace get_time_us() with utun_gettimeofday() for PUSH message timestamps
(db_sync.c, chat_core.c) — monotonic clocks differ across Linux/Windows
- Fix merkle_sync: restart session timer in _handle_request to prevent
double-sided timeout when both nodes start member_sync simultaneously
- Fix INIT_RESP short-format: don't mark synced when my_count > peer_count
- Add db_sync_get_last_timestamp() to avoid duplicate timestamp generation
between db_sync and chat_core on_db_sync_insert
- Fix db_sync_stub to generate timestamps consistently
- build.sh: auto-rebuild chatgui via CMake after utun build
chat_sync_push: add chain_hash parameter, use it instead of zeros
(fixes chain_hash mismatch → all PUSH messages were rejected)
on_db_sync_insert: pass computed chain_h to chat_sync_push
cs_handle_channel_join: call member_sync_start for the joiner
(server now initiates member sync when client joins.
Previously merkle_sync was only started by client → timeout
because server never responded)
cs_handle_welcome: add DEBUG_INFO before member_sync_start on client side
chat_sync_push: fix PUSH format to match cs_handle_push expectations
(was missing insert_record header: ts+dh+nid before ct+dlen+data)
Add DEBUG_INFO log with peer count after send.
on_db_sync_insert: call chat_sync_push after successful local insert
→ new messages are now pushed to all connected peers
Add DEBUG_ERROR to 4 silent returns (JSON parse fail, SQL errors)
chat_core_submit_message: add DEBUG_INFO entry log (ch, ct, len)
chat_core_insert_record: add DEBUG_WARN/ERROR to 7 silent returns
(truncated record, SQL prepare fail, unknown step error)
cs_handle_push: add DEBUG_INFO for ACK send, DEBUG_ERROR for insert fail
cs_handle_send_data: DEBUG_WARN when record truncated mid-loop
cs_on_conn_up: DEBUG_INFO sync path with channel count
Full trace now shows every message: SUBMIT → insert → PUSH → RECV PUSH → ACK
cs_on_conn_down: remove invite state zeroing on disconnection.
Only timeout callbacks and explicit protocol end (CS_MSG_ERROR,
transition to JOIN phase) clear the invite state.
Connection flap now causes automatic retry:
conn_up → pending_invite_ch_id != 0 && !info_req_timer → resend
CHANNEL_INFO_REQ. No deadlock possible.
- cs_handle_init_resp: change silent reject len<37→len<5 (actual payload
sent is 6 bytes, plen=5 after stripping type byte).
Support short format (synced, peer_count+sparse_count) and long format
(divergence, with test_pos+peer_ch). Add INFO logs at each decision.
(fixes sync never starting after invite join — RECV INIT_RESP len=5
was silently rejected)
- All 12 silent return branches in handlers: add DEBUG_WARN with
handler name, peer, ch_id, and reason (makes malformed packets
visible in logs)
- Key sync flow INFO logs:
cs_handle_init_sync: peer_count, my_count
cs_handle_send_data: records sent/received count
cs_on_conn_up: invite vs sync path
chat_core_insert_record: successful insert
- on_db_sync_insert: parse JSON {"n":...,"ct":...,"d":...}, store
d→data, n→node_id, ct→content_type with proper chain_hash
(fixes JSON displayed instead of message text)
- chat_core_cursor_open: SELECT chain_hash column
- chat_core_cursor_next: include chain_hash(32) in output record
- cs_handle_send_data: parse chain_hash in received records
(fixes chain_hash mismatch → all sync records were dropped)
- cs_handle_channel_join: post GUI_EVT_MEMBERS_CHANGED
(fixes creator not seeing new member after join)
- cs_handle_welcome: trigger INIT_SYNC with inviter after join
(fixes no message sync after invite join)
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
