Evgeny ed6132fcda перенос chat-логики из chatgui/transport в src/chat/
- 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

Evgeny 27906e9f91 db_sync: односторонний sync, sparse-таблица, vp в SEND_DATA, PUSH-релей 2026-07-25 15:00:21 +03:00
Evgeny e071a9e2f8 db_sync: fix test sync protocol isolation (add auto_sync flag, destroy order, test refactor)
- utun_instance: fix destroy order (topo_groups before conn_mgr to avoid UAF in topo_recovery)
- topo_recovery: add NULL guard for instance/ua in try_next
- db_sync_instance_add: add auto_sync flag (1=send INIT_SYNC, 0=quiet)
  replaces separate _quiet variant, cleaner API
- db_sync_peer_set_state, db_sync_reinitiate: test-only peer control utilities
- test_db_sync: full rewrite — stable, isolated sync protocol testing
  all 3 branches (peer_empty, hash_MATCH, divergence) tested without PUSH contamination
  Phase 6 extended: triple merge + tail PUSH + mid PUSH cascade on star topology
  runs in 1.4s, consistently passes 10/10
- db_sync_doc: updated protocol architecture description
- chatgui: update db_sync_instance_add call with auto_sync=1

Evgeny c46cb9a979 db_sync: fix si_send_data_batch column bug (author→node_id), add cascade_from to PUSH, add divergence+cascade test phases
- si_send_data_batch: неправильный SQL SELECT с несуществующей колонкой author
  вместо node_id → ломал всю передачу данных в REFINE/SEND_DATA
- Добавлена проверка si_prep и возврат int с кодом ошибки
- Все вызовы si_send_data_batch проверяют возврат, при ошибке сброс sync_state
- db_handle_push: добавлен db_cascade_from после вставки (раньше chain_hash
  не пересчитывался после PUSH)
- db_handle_refine: DEBUG_WARN при scnt==0 (fm за пределами диапазона)
- Добавлена публичная db_sync_chain_verify() для верификации цепочек
- test_db_sync: фаза 4 (divergence через разныe hashes + REFINE/SEND_DATA),
  фаза 5 (PUSH без хвоста + cascade verification)
- Убран мёртвый код db_sync_on_new_conn
- chatgui: адаптивная раскраска пузырей исходящих сообщений

Evgeny fcf3fb7f51 refactor: move transport (etcp/stcp/normalizer) to transport_layer/, routing (bgp/pings/topo*) to routing_layer/ 2026-07-21 20:25:41 +03:00
Evgeny f0bb03c2cf db_sync: datahash removed, Ed25519 signature mandatory, PK=(timestamp,author_signature), chain_hash includes signature, signed message=ts||json 2026-07-17 15:44:19 +03:00
Evgeny 05b24d36bb db_sync: fix dh_match premature sync complete — send tail when mc > tp+1
Root cause: db_handle_init_resp marked sync_state=2 when my_dh==peer_dh
without checking that all my records fit in the confirmed prefix.
If mc > tp+1 (I have records beyond the common prefix), the tail was
never sent — lost records.

Fix:
- Remove special-case 'sc==0 && my_dh==peer_dh' (redundant, same bug)
- In general dh_match: if mc > tp+1, send remaining records [tp+1,mc-1]
  using the same inline loop pattern as 'peer empty' branch

Test: 3 phases covering all dh_match paths:
- Phase 1: B empty+late instance → dh_match at tp=0 (sc=0) → tail-send 49
- Phase 2: A=80 B=50 → dh_match at tp=49 (sc>0, sparse) → tail-send 30
- Phase 3: fresh instances → peer empty → send all 30

Evgeny a7ecee01f5 etcp: replace connections linked-list with indexed ll_queue, add state/ref_count lifecycle
- Remove ETCP_CONN.next linked-list, UTUN_INSTANCE.connections list/count
- Unified connections in single ll_queue indexed by peer_node_id (0=pending)
- struct conn_queue_entry { peer_node_id, conn* } for uniform queue data
- Connection lifecycle via etcp.c: create→pending, conn_ready→indexed, close→detach+deferred free
- Close split: phase1 detach from external world, phase2 deferred via uasync_call_soon
- etcp_conn_set_peer_node_id: reindex on ID change (WARN)
- etcp_conn_ref_take/free: blocking close until refcount returns to 0
- Remove chat_connections — use unified connections queue directly
- Update all iteration/search patterns across 40 files (src + tests + chatgui)

Evgeny f617dcd68e db_sync: LMDB→SQLite, multi-instance, etcp_api, chatgui integration
- src/db_sync: LMDB replaced with SQLite (separate tables per instance: db_sync_name_id)
  TTL index (author, timestamp), WAL mode, per-instance peers/timers
  opaque DB_SYNC_INSTANCE* handle, insert callback, select API
  new fields: author_signature, delivered_peers, delivery_chain
  transport: etcp_api direct P2P (was etcp_router)

- src/db_sync.h: user-oriented API docs, multi-instance lifecycle

- lib/Makefile.am: liblmdb sources removed
- lib/sqlite3.c+h: SQLite amalgamation added

- topo_node: LMDB→SQLite (src/topo_node_sqlite.c moved from chatgui)

- chatgui: real db_sync.c replaces db_sync_stub.c
  chat_core: db_sync_insert_signed + dual-write insert callback
  utun_node: db_sync_init/destroy replaces chat_sync_init/destroy
  CMakeLists: stubs removed, real db_sync.c added

Evgeny e438e19f9e Add cross-platform utun_mkdir() wrapper for Windows compatibility 2026-07-13 06:44:18 +03:00
Evgeny 8756f561be build: extract libutun.a from src/ + add db_sync module + etcp API, BBR improvements
- Add libutun.a (noinst) containing all src/*.c except utun.c
- utun binary now links libutun.a + libuasync.a
- tests/Makefile.am simplified: all tests link libutun.a instead of
  manual .o file lists (removed ~70 lines of boilerplate)
- Add db_sync module: distributed content-addressed DB with LMDB
  backend, peer-to-peer sync via etcp_router (svc 0x20)
- etcp API: etcp_send_in_order(), etcp_clear_inflight_queues(),
  verify_packet_signature(), BBR getters
- BBR: adaptive threshold (1/4 of pipe-min instead of hardcoded)
- route_bgp/etcp_connect: STCP transport support in NODEINFO
- conn_mgr: NODEINFO_ADDRS doc for nat_type/transport/proto fields
- Cleanup: removed AUDIT_FINDINGS.txt, filelist.txt, nat.txt
