Marco Allegretti	7cebac4188	feat(appd): add WebSocket UI endpoint for Servo shell integration ... Implements the weft-appd WebSocket server that allows the system-ui.html page running inside Servo to send requests and receive push notifications without requiring custom SpiderMonkey bindings. ws.rs — WebSocket connection handler: - Accepts a tokio TcpStream, performs WebSocket handshake via tokio-tungstenite accept_async. - Reads JSON Text frames, deserializes as Request (serde_json), calls dispatch(), sends Response as JSON Text. - Subscribes to a broadcast::Receiver<Response> for server-push notifications (APP_READY, etc.); forwards to client via select!. - Handles close frames, partial errors, and lagged broadcast gracefully. main.rs — server changes: - broadcast::channel(16) created at startup; WebSocket handlers subscribe for push delivery. - TcpListener bound on 127.0.0.1:7410 (default) or WEFT_APPD_WS_PORT. - ws_port() / write_ws_port(): port written to XDG_RUNTIME_DIR/weft/appd.wsport for runtime discovery. - WS accept branch added to the main select! loop alongside Unix socket. ipc.rs — Response and AppStateKind now derive Clone (required by broadcast::Sender<Response>). system-ui.html — appd WebSocket client: - appdConnect(): opens ws://127.0.0.1:<port>/appd with exponential backoff reconnect (1s → 16s max). - On open: sends QUERY_RUNNING to populate taskbar with live sessions. - handleAppdMessage(): maps LAUNCH_ACK and RUNNING_APPS to taskbar entries; APP_READY shows a timed notification; APP_STATE::stopped removes the taskbar entry. - WEFT_APPD_WS_PORT window global overrides the default port. New deps: tokio-tungstenite 0.24, futures-util 0.3 (sink+std), serde_json 1.	2026-03-11 09:01:54 +01:00
Marco Allegretti	6f7adc80c5	test(appd): add unit tests for IPC message codec and session registry ... ipc.rs tests (4 tests): - request_msgpack_roundtrip: LaunchApp serializes and deserializes with correct field values. - response_msgpack_roundtrip: LaunchAck round-trips through MessagePack. - frame_write_read_roundtrip: write_frame encodes a 4-byte LE length header + body; read_frame decodes the framed request correctly. - read_frame_eof_returns_none: empty stream returns None without error. main.rs tests (5 tests): - registry_launch_increments_id: each launch returns a strictly increasing session ID. - registry_terminate_known_session: terminate returns true and state transitions to NotFound. - registry_terminate_unknown_returns_false: terminate on missing ID returns false. - registry_running_ids_reflects_live_sessions: running_ids returns all active sessions; terminated sessions are removed. - registry_state_not_found_for_unknown: querying an unknown session ID returns AppStateKind::NotFound. Also extends scripts/wsl-test.sh to run weft-appd tests alongside weft-compositor tests.	2026-03-11 08:32:02 +01:00
Marco Allegretti	538eccd4c6	feat(appd): implement IPC server with Unix socket and MessagePack framing ... Replaces the skeleton bail with a functional IPC server. ipc.rs — transport layer: - Request enum: LaunchApp, TerminateApp, QueryRunning, QueryAppState. Serialized with serde MessagePack (rmp-serde, SCREAMING_SNAKE_CASE type tag). - Response enum: LaunchAck, AppReady, RunningApps, AppState, Error. - AppStateKind: Starting, Running, Stopping, Stopped, NotFound. - read_frame / write_frame: async 4-byte LE length-prefixed codec over any AsyncRead / AsyncWrite. main.rs — server: - SessionRegistry: in-memory HashMap<session_id, AppStateKind> with monotonic ID counter; launch / terminate / running_ids / state. - run(): creates socket parent directory, removes stale socket, binds UnixListener, sends sd_notify READY=1, then accept-loops with ctrl-c / SIGTERM shutdown. Cleans up socket on exit. - handle_connection(): splits stream into BufReader/BufWriter, reads request frames, calls dispatch, writes response frames. - dispatch(): maps Request variants to SessionRegistry operations; returns typed Response. Wasmtime spawning and compositor client deferred to later implementation. New deps: serde (derive), rmp-serde, tokio net/io-util/sync/rt-multi-thread.	2026-03-11 08:25:55 +01:00
