evgeny	f47ad7d87f	tcp_proxy: fix throughput (tx_queue backpressure) + connect timeout + integration test - Router: unified service delivery format [svc_id][src][dst][payload] (end-to-end src/dst from SVC_ROUTE header) - tcp_proxy_client: replace single tx_buf drop-on-backpressure with bounded tx_queue + send_q waiter + retry timer (no data loss, bulk window reopen — removes 62.5ms delayed-ACK stall) - tcp_io: configurable connect timeout (tcp_conn_set_connect_timeout) - tcp_proxy_server: connect_timeout config option (ms, default 2000, 0=off) - check.sh: run tcp_proxy_full integration test with sudo (skip if passwordless sudo unavailable) - test_tcp_io: connect timeout unit test; docs (lwip_nuances.md)	4 weeks ago
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	2 months ago
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)	2 months ago
evgeny	be0e76c9a6	debug: реорганизация категорий — SYS(1), ETCP(4) расширен, CONNECTION(3) очищен; fix stcp_client.c sock_err до connect() Категории: - DEBUG_CATEGORY_SYS=1: u_async + ll_queue + memory + timing (было 4) - DEBUG_CATEGORY_ETCP=4: ETCP + normalizer + BBR (было 3) - DEBUG_CATEGORY_CONNECTION=3: только события статуса линка/подключения (INFO) - DEBUG_CATEGORY_KEEPALIVE=21: только периодический мониторинг (DEBUG) - Удалены: NORMALIZER, BBR, CONNECTIVITY - Устаревшие DB_SYNC → CHAT_SYNC + MEMBER_SYNC (предыдущий коммит) CONNECTION+INFO — только: Connection UP/DOWN, Link UP/down, Link initialized/added, NAT address init/changed, init server/client. CONNECTION+DEBUG — retry, collision, reinit, socket register. KEEPALIVE — init_timer SUPPRESSED, timer started, keepalive skipped. REINIT — ETCP+INFO. Connection status changed — GENERAL (пользовательский callback). Dedup link_status: if(old_link_status) перед Link down. Убран дублирующий Conn:%s из Link down, добавлен link_id в client added link. Молчаливые ошибки: +DEBUG_ERROR в 15 местах (merkle_sync, member_sync, db_sync). Fix: stcp_client.c — socket_get_error() вызывался ДО connect(), проверяя застарелое errno вместо ошибки connect(). Неблокирующий connect() возвращает -1+EINPROGRESS (норма), но сравнивался с мусором → ложный FAIL. Все 4 STCP-теста исправлены (68/68 pass).	2 months ago
jeka	7139969acd	fix: Windows/MSYS2 build compatibility - proxy/icmp_proxy.c: define struct icmp/ip + ICMP constants for _WIN32 - lwip_tcp_priv.h: use #include <winsock2.h> instead of #define htonl/htons - lwip_tcp.h/c: rename poll field to pollfn (avoid WSAPoll macro conflict) - tests: guard Unix-only headers with #ifndef _WIN32, skip fork/socketpair tests	3 months ago
Evgeny	0dd942be63	fix: стабилизация тестов test_tcp_io и test_bbr_integration - test_bbr_integration: bbr_max_cwnd=100KB (16×BDP) — устранён overshoot очереди - test_tcp_io: адаптирован под EPOLLHUP на socketpair (send до poll, error_cb вместо fin) - tcp_io: расширенная диагностика error_cb с состоянием сокета	4 months ago

Evgeny	b953a6daf0	tcp_io: FIN/close через write_queue, отладка всех этапов закрытия - tcp_io.h/c: push_fin/push_close через очередь отправки Кодирование: dgram=NULL→close, len=0+dgram!=NULL→FIN (sentinel) FIN: shutdown(SHUT_WR), стоп чтения, on_fin_sent CLOSE: close сокета, on_closed read_cb: отбрасывание входящих после fin_sent guard wq_fetch: error\|\|closed (не fin) - tcp_proxy_server: адаптация handle_fin→push_fin, handle_close→push_close read_queue_drain_cb: discard при fin_sent DEBUG_INFO на всех точках закрытия - tcp_proxy_client: send_fin, handle_fin — DEBUG_INFO - test_tcp_io: +6 тестов (push_fin, push_close, ordering, double-push, fin+close)	4 months ago
Evgeny	04f6b3e040	refactor: remove tcp_conn_push_write, use direct queue put with chunking External code pushes to write_queue directly (entry_pool + data_pool). Added queue_set_threshold(write_queue, 32, 0) for write backpressure. Tests split data into write_chunk_size chunks before queue put.	4 months ago
Evgeny	63f019530b	feat: tcp_io library + uasync socket toggle + ll_queue empty_callback lib/u_async: uasync_set_socket_read/write — O(1) EPOLL_CTL_MOD toggle per socket lib/ll_queue: queue_set_empty_callback — one-shot deferred callback on queue drain lib/tcp_io: TCP connection management via uasync + ll_queue with pool alloc - read: direct recv into pool buffer, high/low water flow control - write: autofetch via ll_queue callback, partial send via write_buf - on_fin/on_error/on_flushed callbacks, FIN deferred until read_queue drained - getpeername for pre-connected socket detection tcp_proxy_server: migrated to tcp_io (22→13 fields, 437→270 lines, -7 functions) tests: test_tcp_io (5 tests), test_tcp_proxy_server rewritten for tcp_conn	4 months ago
