- chat_core_sync_my_addresses(): remove private IP filter (192.168, 10.x, etc.)
so LAN addresses are stored for direct connections
- topo_node_sqlite_channel_peers_all(): include peers without addresses
in WELCOME message (was skipped entirely, causing empty peer list)
- chat_core_create_channel(): pass real local addresses to member_sync_put()
instead of NULL,0
- chat_core_init(): log number of channels loaded from DB on startup
sc_derive_node_id() hashed the private key, while invite links
(joindialog.cpp) hashed the public key — giving two different
node_ids for the same keypair.
Removed sc_derive_node_id(), kept only sc_derive_node_id_from_pubkey().
All callers updated to use pubkey-based derivation.
- topo_sqlite_db moved from TOPO_GROUPS to UTUN_INSTANCE (direct access)
- topo_groups_set_sqlite_db() removed
- chatgui: chat_sync_connect_node → chat_core_connect_auto (direct ETCP, no conn_mgr)
- chatgui: chat_core_connect_from_invite saves to SQLite → auto connect (no BGP)
- chatgui: removed _on_node_updated BGP callback from member_sync
- chatgui: removed conn_mgr_get_status from status dump
- chatgui: removed all conn_mgr.h and topo_group.h includes
- chatgui: CONN_MGR_ERR_* constants → CC_* in chat_core.h
- removed unused cc_parallel_* code, conn_state_str/conn_type_str helpers
- db_sync_on_conn_up: per-instance synced/skipped counters
- db_sync_peer_check_cb: summary INFO of check results
- db_sync_instance_add: peers_found + peers_synced counts
- db_handle_init_sync/initiate_sync: enhanced with tbl name
- db_handle_init_resp: tp + my_mc in sync complete/dh match
- db_handle_send_data: range + SYNC_DONE details; stop reason when mc>pk
- db_handle_sync_done: both counts + datahashes in mismatch; dh in confirm
- db_sync_recv_cb: INFO when instance NOT FOUND (timing race)
- cs_handle_channel_info_resp: sync readiness after channel ready
- cs_handle_welcome: note about db_sync peer_check timer
- on_db_sync_insert: counter (#1-3 then every 10) with ch/n/ts/dh/ct
Priority: iterate instance->connections for links with NAT_TYPE_DIRECT
(connected and reachable). Fallback: own socket addresses.
Removed broken getOnlinePeerAddresses() which returned other nodes' addresses.
- chat_core.c: CREATE TABLE IF NOT EXISTS peers_* in ensure_channel_ready
- utun_node.cpp: GUI_ERROR redirected to debug log file via guiDebugFile()
- etcp_connections.c: reuse unindexed outbound conn (peer_node_id==0)
on cross-connect INIT to avoid 'Can not insert link to socket'
- cs_find_conn_for_node: show queue state, entry found/missing, conn flags
- cs_on_conn_up: log when skipping due to !initialized
- etcp_conn_queue_set_ready: log reindex details (old/new entry, count)
- etcp_conn_set_peer_node_id: show state+reindexed flag
- utun_instance.h: add chat_connections queue (indexed by node_id, 8 bytes)
- chat_sync.c: queue_new in init, queue_free in destroy, queue_find_data_by_index in cs_find_conn_for_node
- chat_sync.c: remove from queue in cs_on_conn_down
- chat_core.c: add to queue in connect_from_invite and connect_auto
- chat_core.c: remove from queue in cc_parallel_cleanup and ca_cleanup
- db_sync.c: replace linear conn search with queue_find_data_by_index (db_sync_send_hash)
- etcp_connections: keepalive SEND/RECV/DECRYPT_OK: DEBUG→TRACE; DECRYPT_FAIL: WARN→DEBUG
- db_sync_on_conn_up: skip sync if !conn->initialized, wait for next UP event
- db_sync peer_check_timer+instance_add: also check conn->initialized
- chat_sync cs_on_conn_up: ignore conn_up before initialized (cs_send fails otherwise)
- db_sync_on_conn_up log now includes init= and links=
- 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
Replace etcp_router_bind/etcp_route_send/etcp_router_unbind with
direct etcp_bind/etcp_send/etcp_unbind + find-conn-by-node_id helpers.
Same approach as db_sync (0x20). Service IDs unchanged (0x30, 0x31).
ca_ready_cb and cc_parallel_ready_cb called etcp_connection_close
synchronously on non-selected connections from within the ready_cbk
callback chain. This corrupts senders_list in topo_group, causing
UAF in topo_group_start_link_nat_check.
Now uses uasync_call_soon (zero-delay timer) to defer the close
to the next event loop iteration, after the callback chain completes
and callbacks_running flag is reset.
- Added struct ca_ctx** ctxs to ca_state (parallel array)
- ca_cleanup now frees all ctxs[i] and the ctxs array
- ca_ready_cb: removed u_free(ctx), added etcp_conn_remove_ready_cbk before cleanup
- ca_timeout_cb: removed u_free(ctx) — ctx lives until ca_cleanup
- All error paths set ctxs[i]=NULL for ca_cleanup safety
etcp_connection_create does NOT add conn to inst->connections list.
Without this, incoming INIT handler can't find the outbound conn
by peer_node_id and creates a new one, causing insert_link collision.
- ca_timeout_cb: removed etcp_connection_close, ETCP lives past 3s timeout
- ca_state.cancelled flag + chat_core_connect_auto_cancel() for external cancel
- chat_core_connect_auto returns ca_state* via out_state
- Rewritten auto_connect: cursor (ch,peer) instead of bulk collect
- GC every 1s: closes flights with no link_status after 3s
- ac_result_cb no longer clears ca_state (GC handles cleanup)
- stop: cancels all flights via chat_core_connect_auto_cancel
- 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
- 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.
