Generate client-side protocol types from weft-shell-unstable-v1.xml
using wayland-scanner, following the same module structure as the
compositor server side.
- crates/weft-servo-shell/src/protocols/mod.rs: generate_interfaces!
inside __interfaces submodule, generate_client_code! at client module
level, with use wayland_client in scope. Re-exports
ZweftShellManagerV1 and ZweftShellWindowV1 for use by embed_servo
once the Wayland connection is established.
- New deps: wayland-client, wayland-backend, wayland-scanner, bitflags
(version-matched to existing workspace resolution).
The binding compiles but is not yet wired into embed_servo(); that
connection is deferred until the Servo embedder contract is ready.
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).
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)
Add full DRM/KMS backend with libseat session, GBM allocation, EGL
display initialisation, and a GpuManager-driven rendering loop.
- drm_device.rs: type aliases and per-device/per-output state structs
(WeftDrmDevice, WeftOutputSurface, WeftDrmData)
- drm.rs: replace skeleton with complete backend libseat session,
udev device enumeration, libinput event source, connector scanning
via smithay-drm-extras DrmScanner, DrmOutputManager initialisation
per CRTC, VBlank-driven render_output, sd_notify(READY=1)
- state.rs: add drm: Option<WeftDrmData> field; route dmabuf import
through GPU manager when the DRM path is active
- Cargo.toml: add renderer_multi, use_system_lib Smithay features;
add smithay-drm-extras and sd-notify Linux dependencies
render_output submits a clear-colour-only frame to establish
the VBlank pipeline. Surface compositing is wired up in a subsequent commit.
