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
Marco Allegretti	c7ad2116a0	feat(appd): add weft-appd skeleton crate and service unit ... New crate implementing the application daemon entry point: - crates/weft-appd/Cargo.toml: tokio (current-thread runtime), anyhow, sd-notify, tracing dependencies - crates/weft-appd/src/main.rs: async run() resolves IPC socket path from WEFT_APPD_SOCKET or XDG_RUNTIME_DIR/weft/appd.sock; stubs for AppRegistry, IpcServer, CompositorClient, RuntimeSupervisor, CapabilityBroker, ResourceController per WEFT-OS-APPD-DESIGN.md; sd_notify(READY=1) to be sent after IpcServer bind + CompositorClient connect - infra/systemd/weft-appd.service: Type=notify, Requires+After weft-compositor.service, After servo-shell.service Also fix two winit backend issues that were present in the working tree: - remove spurious mut on display binding (never mutated after init) - wrap std::env::set_var in unsafe block (required since Rust 1.80)	2026-03-11 01:13:18 +01:00
