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
- conn_mgr_core.c: убрана запись node_name из cm_handle_invite_info_resp

- 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')
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.
- 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
- 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
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
- uasync_set_timeout(0): use FIFO immediate_queue instead of timeout_heap
to guarantee execution AFTER all currently-expired heap timers
- uasync_cancel_timeout: search immediate_queue for timeout=0 timers
- dummynet: start initial shaper with bandwidth-based delay instead of 0
(prevents queue from never filling up when packets arrive sequentially)
- test_dummynet: rename get_time_us -> now_us (conflict with u_async.h)
- test_u_async_comprehensive: fix immediate_timeouts, add timeout_ordering test
- build.sh: added --full flag for full rebuild (autoreconf + configure + make)
- build_direct.sh: incremental compilation (skips unchanged files)
- build_full.bat: new Windows batch for full rebuild
- configure.ac: fixed Windows detection using AC_COMPILE_IFELSE
- lib/u_async.c/h: Windows wakeup socket support, uasync_post for thread-safe callbacks

- Fix Wintun adapter creation to open existing adapters first
- Add debug category for control server operations
- Update build files to include control server in compilation
- Add test_control_server to test suite
- Remove FD_SETSIZE check for Windows sockets (can have any value)
- Fix process_timeouts to handle all expired timers (continue instead of break)
- Handle case when no sockets to poll (sleep instead of calling poll)
- Disable wakeup pipe on Windows (incompatible with WSAPoll)
- Add gettimeofday and ssize_t implementations for Windows
- Add platform_compat.h with Windows implementations of:
* gettimeofday() using GetSystemTimeAsFileTime
* poll() using select()
* pipe() using _pipe()
* fcntl() using ioctlsocket for O_NONBLOCK
* pollfd structure and POLL* constants
* strcasecmp/strncasecmp macros
- Update debug_config.c and u_async.c/h to use platform_compat.h
- Remove POSIX-specific headers (arpa/inet.h, sys/time.h, etc.)
- All 22 tests pass on Linux
- Fixes build errors on Windows MSYS2
- Add socket_compat.h/c with platform abstraction for POSIX/Windows
- socket_t typedef: int on POSIX, SOCKET on Windows
- Add socket_platform_init/cleanup for WSAStartup on Windows
- Add socket operations: create_udp, sendto, recvfrom, set_nonblocking
- Add socket options: set_buffers, set_reuseaddr, set_mark (Linux), bind_to_device (Linux)
- Update u_async: add socket_t support with uasync_add_socket_t/remove_socket_t
