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	fcf3fb7f51	refactor: move transport (etcp/stcp/normalizer) to transport_layer/, routing (bgp/pings/topo*) to routing_layer/	2 months ago
Evgeny	93871c592b	db_sync: timeout for stuck sync_state=1, handle ERROR properly - Add sync_start_tb to SI_PEER, set in db_sync_initiate_sync - peer_check_cb: after 15s timeout reset sync_state=0 with WARN - db_handle_error: accept si, reset sync_state=0, DEBUG_ERROR with details - DB_SYNC_SYNC_TIMEOUT=15 added to db_sync.h	3 months ago
Evgeny	3d04c37f56	stcp: add on_close callback to stcp_server_create/stcp_client_connect; member_sync: add join_ts/update_sig/update_ts fields, verify update_sig in apply; topo_node_sqlite: add join_ts/update_sig/update_ts to member_put, add member_get_join, add node_update_verified; chat_sync: include join_ts in join_msg, add update_sig/update_ts to CHANNEL_INFO_RESP; WELCOME verify join_sig; tests: use generated node_ids, reduce max ticks	3 months ago
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)	3 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	ba14e31e09	fix: remove retry_timer, use waiter-based round-robin on send_q for fairness - tcp_proxy_server: drain_cb uses etcp_router_on_send_ready instead of retry_timer - socks_proxy: on_read_cb + tx_waiter_cb use etcp_router_on_send_ready instead of waiter_register - Result: FIFO round-robin via ll_queue waiters on send_q, all streams get fair share - No timers — wakeup is event-driven via queue_data_get → check_waiters - TCP backpressure: read_queue callback_suspended prevents over-reading	3 months ago
Evgeny	5b850ea5da	test: add profiling (MB/s per file per worker) to socks_http_proxy	3 months ago
Evgeny	2fba5c31c4	fix: backpressure data loss in socks/http proxy + comprehensive test socks_proxy (client side): - tx_buf buffering on send_data failure in RELAY path, retry in tx_waiter_cb - process_http_request: version_str null-term fix (memcpy(vlen)+explicit \0) - process_http_request: assemble hdr+body+extra into heap pkt, atomic send - socks_proxy_handle_etcp: alloc failure logs write_queue state + byte counters tcp_proxy_server (exit node): - read_queue_drain_cb: tx_buf buffering on backpressure, retry_timer (500ms, force=1) - on_fin_cb: defer FIN when read_queue+tx_buf has pending data (dst_fin_deferred) - handle_data + drain_cb: per-stream byte counters (sent/recv/relayed/drain_count) - on_fin_cb/on_error_cb: detailed state logging (counters, queues, buffers) test_socks_http_proxy: - 4 workers: socks_ipv4, socks_domain (DNS resolution via SOCKS), http_proxy, https_connect - 4 file sizes: 1KB, 100KB, 1MB, 10MB — deterministic content, byte-by-byte cmp -s - HTTPS server with self-signed cert, POST/echo, HEAD, OPTIONS - 51/51 tests PASS	3 months ago
Evgeny	2cb85cbc3d	socks_proxy: поддержка HTTP-прокси (GET/POST/HEAD/OPTIONS/...) — не только CONNECT process_http_request() теперь обрабатывает любые HTTP-методы: - CONNECT — туннель как раньше, без изменений - GET/POST/PUT/HEAD/OPTIONS/... — парсинг абсолютного URL, DNS, send_connect + пересборка строки с относительным путём + тело DATA test_socks_http_proxy: +3-й worker (http_proxy через -x без --proxytunnel), +проверки POST (echo), HEAD (200 OK), OPTIONS (Allow). Все 78 проверок — PASS.	3 months ago
Evgeny	de8cce521a	all 51 tests pass: fd=0 protection + clean socks_http_proxy test - socket_compat: never close fd=0 - socks_http_proxy: rewritten cleanly, 2 workers, 25 reqs each, up to 100KB - uasync_socket_race: dup2-based fd=0 reservation - u_async: removed DIAG spam - tcp_io: removed debug fprintf Result: 51/51 tests pass.	3 months ago
Evgeny	a01e2f0899	tun_enabled config + socks/http stress test (50 reqs, 2 workers) - config_parser: tun_enabled в [global] (по умолчанию yes), не дефолтить tun_ifname если TUN не нужен - utun_instance: уважать tun_enabled, чистые дефолты tcp_proxy TUN - socks_proxy: фикс дэдлока — reply сразу после CONNECT, без ожидания DATA - utun.conf.sample: документирован tun_enabled, tun_ifname - test_socks_http_proxy: 50 запросов (SOCKS+HTTP), 2 воркера параллельно, файлы 1k..100k, сверка через cmp, python http.server + curl	3 months ago
