evgeny f28d3e91f7 media: рефакторинг загрузки блоков — конечный автомат, фейловер, watchdog простоя 
- media_download: состояние блока (IDLE/CONN/REQ/RECV/WAIT/DONE/FAILED),
  кандидаты-держатели (MD_MAX_HOLDERS_PER_BLOCK), фейловер + ретраи (MEDIA_DL_MAX_ATTEMPTS),
  watchdog простоя (MEDIA_DL_STALL_TIMEOUT_TB) вместо фейкового времени
- media_delivery: настраиваемые dl_stall_timeout_tb / dl_max_attempts
- chat_msg: пометка ошибки скачивания в local_attrs ("st":"er") для UI
- tests: новый test_media_download_timeout (watchdog/фейловер), рефакторинг
  test_media_delivery_download/full
- chatgui-android: состояние 'error' у вложений/видео (иконка + tap to retry)

evgeny 2d04bf941b etcp_router: вынести подпись/шифрование в route_crypto, одна функция отправки с флагами 
- route_crypto_encode/decode: автономный пред/пост-обработчик пакета
  (encrypt-then-sign, стандартный Ed25519 вместо sc_stream_sign)
- одна функция отправки etcp_route_send/etcp_router_conn_send с bitmask mode
- формат доставки: [svc_id][src][dst][rx_flags][payload] (статус подписи/шифрования)
- ROUTER_INFLIGHT хранит финальный wire-пакет (чинит потерю подписи при ретрансмите)
- дедуп инициализации: router_conn_reset/free_queues
- учёт inflight через inflight_q count (seq присваивается на enqueue)

evgeny 326dfd7e2c media_delivery: маршрутизация всегда через CHAT-группу 
media_download/медиа-ответы и суперузловая репликация теперь берут группу
из контекста (dl->group_id, group_id из пакета, peer->group_id) вместо
хардкода TOPO_GROUP_UTUN. node_props_changed получает channel_id.
SUPER_HELLO несёт group_id.

evgeny 5c2501b4f3 chat: BGP-driven address sync, member identity verify, join_sig fix 
- Адреса узлов вынесены из wire-протокола member_sync/merkle/join/welcome
  в BGP/topo_group: node_addresses теперь пишет только topo_node_sqlite_addrs_put
  (источник истины ni->v4/v6_addrs), классификация config_type/nat_type в sockmeta
- Жёсткая анти-подделка: node_id=derive(x25519), ed25519 сверяется с доверенной
  таблицей nodes, NODEINFO node_id/pubkey mismatch отклоняется как forgery
- Единые member_sync_build_join_msg (112Б) и member_sync_build_update_msg:
  устранён баг _verify_join_sig (join_ts по смещению 80 вместо 104, длина 104→112),
  который рушил приём мемберов; все 7 мест подписи/проверки join_sig через хелпер
- Единое обновление своего мембера chat_core_update_my_member (вместо sync_my_addresses)
- Android standby: пауза таймеров (broadcast/db_sync/merkle_sync/chat_sync) через standby_wait
- name[16] → name[MAX_CONN_NAME_LEN] с truncation-warning в парсере
- conn_mgr: etcp_connect_cancel_by_node (use-after-free при отмене invite),
  промоушен conn в ncd после успешного invite
- Android GUI: foreground-gating опросов, сохранение портов интерфейсов, фикс udp-log flush
- chatgui: персистентный db_path; мелкие DEBUG-логи epoll/pool

evgeny 4bb9f9e9c2 crypto: EVP_PKEY_generate → EVP_PKEY_keygen + OPENSSL_API_COMPAT для BSD/LibreSSL 2026-08-09 13:59:38 +03:00
evgeny 38c9f229bc stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test 
- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll
- stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close
- utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP),
  add deferred drain in both Phase J and L
- stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39,
  exchange ed25519_pubkey in both handshake directions
- etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in
  etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb
- chat_sync.c: fix lk->conn NULL dereference for TCP links
- test_stcp.c: update stcp_server_create/stcp_client_connect callsites
- tools/chat_tcp_test: change transport udp→tcp
 2026-08-07 00:48:27 +03:00
evgeny d773f1724a refactor: STCP connections as ETCP links (is_tcp) 
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
  etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

Desktop (Qt/C++):
- messagedelegate.h: MsgFileDownloadStateRole, MsgChannelIdRole
- messagelist.cpp: parse localAttrs for file download state
- messagedelegate.cpp: FileBubble with download icon/text + click handler via chat_core_attachment_download_trampoline
- gui_bridge.h: GUI_EVT_ATTACHMENT_DOWNLOADED (14) + callback typedef
- gui_bridge_impl.cpp: event dispatch + setter
- mainwindow.cpp: callback registration -> refresh message list

evgeny b8920cf483 chat_settings: [chat] config section + live sync + fix test segfault 
- New chat_setting.c/h: unified chat settings API (int/str getters)
- Config parser supports [chat] section, calls chat_setting_set per key
- chat_core exposes chat_core_set_setting / trampoline for GUI bridge
- chatgui: AudioDevice + Storage pages persist to [chat] config + live apply
- chatgui-android: ConfigProvider, NativeLib, headless handle chat settings
- MessageList: 200 msg limit, fixed saveChannelState via trampoline
- test_media_delivery_full: fix segfault at shutdown (mon() timer vs freed conns)
 2026-07-29 21:18:49 +03:00
evgeny efbb495016 media_delivery: fix SUPER_REPL spam + streaming verification 
Bugs fixed:
- md_super_peer_add: timeout_tb = 0 → MEDIA_REPL_TIMEOUT_TB (timer fired every poll)
- md_repl_retrans_cb: md from peer->connect_timer (garbage) → peer->md
- md_repl_retrans_cb: removed inflight_count=0 reset (don't resend acked entries)
- stream_ctx: removed unused block_data field (was NULL, caused crash in BLOCK_DONE)

Test improvements:
- stream_completed flag for reliable streaming verification
- File created in <db_dir>/media/ (matches media_index path logic)
- 9/9 full test, 33/33 total
 2026-07-29 20:42:47 +03:00
evgeny b4824de3b8 media_delivery: fix streaming crash, correct file path via media dir 
- Fix NULL block_data deref in stream_send_chunk_cb
- Test B1: create file in <db_dir>/media/, commit to media_files
- Store media_base in ui_state for streaming handler path resolution
- 8/9 tests pass (streaming works but timing issue with SUPER_REPL flood)
 2026-07-29 20:16:47 +03:00
evgeny a6321e15b3 media_delivery: streaming, fallback, admission control, 8/9 tests 
- md_handle_block_req: real chunk streaming via etcp_router_on_send_ready
- stream_ctx state machine: backpressure waiter → send chunk → repeat
- content_hash + block_sig on stream completion
- Fallback to author when supernode has no block info
- media_download: author_node_id for peer fallback
- test_media_delivery_full: 8/9 pass (SUPER_HELLO, HAVE_BLOCK, replication, admission, file create)
- Known issue: streaming test hung (BGP route for n1→n2 not established in time)
 2026-07-29 19:52:13 +03:00
evgeny 57e6ffed16 media_delivery: admission control + OVERLOADED + full integration test 
- MEDIA_BLOCK_OVERLOADED (0x0F) subcommand + packed struct
- Admission control: track active_streams, reject > 3 with OVERLOADED
- media_delivery_stream_done() to decrement counter after stream finish
- Auto-download trigger in chat_msg.c (parse media metadata, check settings)
- test_media_delivery_full.c: 9/9 tests on 4 instances
  (SUPER_HELLO, HAVE_BLOCK, replication, admission control, OVERLOADED)
- All 33 existing tests still pass (15+5+4+9)
