- Remove is_dm column from channels table (dm detection by member count)
- Rename member name column to userinfo — extensible json_flat format
- Add json_flat.c/h library for compact JSON serialization
- Fix join_sig message format: use ch_x25519+ch_ed25519 instead of channel_id string
- Remove name from join_msg body (now in userinfo via json_flat)
- Update chat_core, chat_sync, member_sync, db_manager to new format
- Add topo_strategy.txt — архитектурные заметки по топологии
Remove secondary level filtering in debug_output(). Now the only filter
is debug_should_output() (per-category + global fallback). Output goes
to file (if file_output set) or console (if console_enabled), with no
additional level check.
Removed:
- debug_set_console_level(), debug_set_file_level()
- console_level, file_level fields from debug_config_t
- debug_set_level() no longer sets console_level
New category (id=25) replaces DEBUG_CATEGORY_DEBUG in chat_sync and
chat_core. This allows enabling only protocol-level logs (SEND/RECV,
timeouts, handshake) without the noise from DEBUG category.
Changes:
- debug_config.h: add CONNECTIVITY=25, COUNT→26
- debug_config.c: add 'connectivity' to g_debug_categories
- chat_sync.c: DEBUG→CONNECTIVITY in all protocol logs
- chat_core.c: DEBUG→CONNECTIVITY in connection/create logs
- utun_node.cpp: remove hardcoded DEBUG=TRACE (now config-driven)
- chatgui.cfg: connectivity=info in debug_categories
- Add CreateGroupDialog with group name input
- Generate X25519+Ed25519 keypairs, random uint64 channel_id,
Ed25519 signature, write to DB via uasync thread
- chat_core_create_channel(): create msg table, topo_node_sqlite_channel_put()
- GUI_EVT_CHANNEL_UPDATED notification to reload channel list
- Per-category debug config: debug_level= + debug_categories= in [gui]
- Unified logging via debug_config: all threads write to same file/console
- debug_enable_console(1) to mirror file output to stderr
- DEBUG_LEVEL_DISABLED=-1: truly disable category, NONE=0 fallback to global
- Fix uasync_post under epoll: process_posted_tasks was never called
- Fix MainWindow constructor parameter ordering (dbPath vs debugFile)
- debug_ui.h: append mode ('a' instead of 'w')
Added #ifdef __cplusplus / extern "C" { ... } / #endif to ~65 headers
in src/ and lib/, enabling the C library to be linked into C++ code (chatgui).
Fixed packet_dump.h (added missing header guard) and etcp_bbr.h
(#pragma once guard).
В одном epoll_wait batch три события для fd: EPOLLERR (освобождает tc),
EPOLLIN (read_cb), EPOLLOUT (write_cb). read_cb/write_cb guard проверяет
tc->sock==SOCKET_INVALID, но sock обнулялся ПОСЛЕ on_error.
Перенос sock=SOCKET_INVALID до on_error защищает от use-after-free.
Доказано: без фикса segfault на tcp_io.c:374 (write_cb → tc->connected).
С фиксом тест работает без крашей.
tcp_conn_handle_error гвардил uasync_remove_socket_t по tc->socket_id,
пропуская повторный вызов. В одном epoll_wait batch два события
(EPOLLERR + EPOLLOUT) на один fd: первое делает remove (socket_id=NULL),
второе проходит guard и dispatch'ит write_cb на освобождённом tc.
Фикс: всегда вызывать uasync_remove_socket_t + epoll_ctl(DEL),
независимо от socket_id.
- pkt_normalizer: save recvpart->len before queue_data_put (may free synchronously)
- ll_queue: save uasync_call_soon handle in queue_waiter_handle, cancel on free
- uasync: generation counter in epoll data.u64 to skip stale events after fd reuse
- uasync: keep fd_to_index mapping after socket_array_remove for inactive nodes
- test: test_uasync_socket_race — 4 children × 200 iterations, currently flaky
- Add ed25519_public_key[32] to NODEINFO struct for pubkey distribution
- Add ed25519_public_key[32] to ROUTE_BGP (derived from X25519 privkey at init)
- Add ROUTER_FLAG_SIGNED (0x08) to SVC_ROUTE_HDR flags byte
- router_send_one_flags: when is_signed, sign [hdr][payload] and append 64-byte sig
- etcp_router_recv_cb: verify Ed25519 signature when ROUTER_FLAG_SIGNED set
- New API: etcp_router_conn_send_signed()
- Drop signed packets if sender node not in routing table or no Ed25519 key
- 5 unit tests in test_etcp_router_unit.c covering OK/tampered/unknown/no-key/short
- debug_get_category_name(): replace switch/case with table lookup in g_debug_categories[]
- etcpmon_gui: remove hardcoded cat_names[], create labels/radios dynamically from server CSV
- Add acked_bytes/acked_packets to struct ETCP_LINK (init, reset, increment per ACK)
- Add DEBUG_CATEGORY_BBR (23) for BBR-specific debug output
- Add BBR input/output DEBUG_DEBUG around bbr_main call in etcp_ack_recv
- Add "bbr" category name to debug_config and etcpmon GUI
- Вынесена общая логика обработки фатальных ошибок сокета
- Обработчик: close сокета, обнуление коллбэков, аварийный drain, вызов on_error
- Устранён use-after-free: пулы освобождаются до вызова on_error
- flush_write_buf возвращает int (0=ok, 1=error/tc destroyed)
- Все ошибки аллокации write_buf ведут к вызову on_error (ENOMEM)
- Обновлён header: документация в актуальное состояние
- etcp_link_update_inflight_lim: self-contained method with clamping,
send_blocked_inflight check, loadbalancer_link_ready on cwnd increase
- etcp_conn_on_inflight_lim_changed: recalc optimal_inflight + resume input
- etcp_ack_recv: use etcp_link_update_inflight_lim instead of manual set
- etcp_request_pkt: fix line 928 check old link (inf_pkt->last_link) not new
- etcp_link_close: recalc optimal_inflight on link removal (both branches)
- etcp_socket_remove: fix dangling pointer loop (nullify after close)
- uasync_print_resources: show timer names, remain time, deleted entries
- diagnostics in utun_instance_destroy and test_etcp_reconnect
memory_pool: memory_pool_is_freed(pool,obj) — поиск obj в free-списке
tw_pcbs (3 места): !ctx→halt и is_freed→halt в начале итерации
— ловит висячий PCB до re-alloc и после re-alloc
etcp: is_freed→halt перед etcp_conn_input (caller + callee)
— ловит pkt освобождённый до входа
tcp_alloc: убран старый скан tw_pcbs (заменён на is_freed)
все dangling проверки — halt (while(1)) вместо break/return
memory_pool: +2 байта за объектом — canary 0xAA для детекции buffer overflow,
counter для детекции double-free. При free проверяется canary и counter==0,
при alloc выставляется новый counter.
lwip_tcp: убраны TCP_TW_MAX и счётчики tw_iter (толку нет, краш на 2й итерации).
Оставлены: !pcb->ctx (dangling pointer), self-loop checks, next_owner диагностика.
Добавлена проверка в tcp_alloc: если новый PCB найден в tw_pcbs → halt.
tcp_conn_destroy: set read/write queue callbacks to NULL before
queue_free to stop deferred autofetch (drain_cb on freed rc).
write_on_get_cb: throttle consumer_ack to every 8th write_queue
dequeue instead of every single one (was 30+ ACK/sec).
ack_batch field in tcp_proxy_server_conn.
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.
