- chat_core.c: dump node_addresses total, per-node counts, nodes lookup before addr query
- topo_group.c: log db path, rc, and db pointer after sqlite3_open
- topo_group.c: open {db_path}/chats.db instead of {db_path} — was opening a directory
- chat_core.c: remove inst->topo_sqlite_db = g_cc.db — keep topo_sqlite_db as separate
uTun-only connection without FULLMUTEX, avoiding contention with GUI reads
- chat_core.c: add DEBUG_INFO before each synchronous cb(FAIL) — pinpoints exact failure reason
- chat_sync.c: add log in ac_fill when ca_state=NULL after chat_core_connect_auto call
- Add etcp_add_conn_status_cbk/remove/set — unified callback for all connections
- 4 statuses: NEW, UP, DOWN, DELETE — one subscription covers all connections
- Fire points in etcp.c: create→NEW, on_up→UP, on_down→DOWN, close→DELETE
- chat_sync.c: replace cs_on_new_conn+per-conn subs with cs_on_conn_status
- db_sync.c: same migration to instance-level callback
- cs_is_peer_online: use conn->links_up instead of link->link_status (was 0 during INIT handshake)
- db_sync: rename column author→node_id, open chats.db instead of sync file,
db_sync_instance_add takes table_name directly
- chat_core: remove CREATE TABLE msg_ch_*, remove on_db_sync_insert (74 lines),
remove fallback INSERT in submit_message, add minimal on_msg_inserted
for GUI notification only
- db_manager: update getMessages for new schema (parse JSON from data column),
fix ORDER BY to use author_signature instead of datahash,
update syncCursorNext to parse JSON
- si_register simplified: db_count from same table, no more msg vs sync gap
- chat_core_has_conn: search all connections (pending+ready) by peer_node_id
- chat_core_connect_from_invite: skip chat_core_connect_auto if already connected
- ca_timeout_cb: close timed-out connection to free socket link slot
+ cancel remaining timers + ca_cleanup on all-failed
- cs_handle_welcome(): add self to local peers_<ch_id> so
joiner sees own account in channel member list
- cs_on_conn_up(): post CHANNEL_PEERS_ONLINE after reconnect
so GUI shows connected status (was only posted on conn_down)
- etcp_loadbalancer: DEBUG_WARN -> DEBUG_DEBUG for no suitable
link: tmr:wait — normal shaper behavior, not a warning
- 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).
