Adds weft-compositor/src/appd_ipc.rs: WeftAppdIpc state, setup() registers a calloop
UnixListener source. Accepted connections are registered as edge-triggered read sources.
Incoming AppdToCompositor frames are decoded and dispatched; AppSurfaceCreated records
pid->session mapping in pending_pids for later wl_surface association. Wires into both
the DRM and Winit backends. Socket path: /weft/compositor.sock or
WEFT_COMPOSITOR_SOCKET override.
Add the WEFT compositor-shell Wayland protocol and wire it into the
compositor state.
Protocol definition:
- protocol/weft-shell-unstable-v1.xml: defines zweft_shell_manager_v1
(global, bound once by servo-shell) and zweft_shell_window_v1
(per-window slot). Requests: destroy, create_window,
update_metadata, set_geometry. Events: configure, focus_changed,
window_closed, presentation_feedback.
Generated code + bindings:
- crates/weft-compositor/src/protocols/mod.rs: uses wayland-scanner
generate_interfaces! inside a __interfaces sub-module and
generate_server_code! at the server module level, following the
wayland-protocols-wlr crate structure. Exports WeftShellState
(holds the GlobalId) and WeftShellWindowData (per-window user data).
Server-side dispatch (state.rs):
- GlobalDispatch<ZweftShellManagerV1, ()>: binds the global, inits
each bound resource with unit user data.
- Dispatch<ZweftShellManagerV1, ()>: handles create_window by
initialising a ZweftShellWindowV1 and sending an initial configure.
- Dispatch<ZweftShellWindowV1, WeftShellWindowData>: handles
update_metadata (stores advisory data) and set_geometry (echoes
compositor-adjusted configure back to client).
WeftCompositorState.weft_shell_state initialised in new() alongside
all other protocol globals.
New direct deps in weft-compositor: wayland-scanner, wayland-server,
wayland-backend, bitflags (all version-matched to Smithay 0.7).
