Integrate native Rime and stabilize input, output, and rendering

Browse Source 
- Add optional modifier-only Super binding whose tap is cancelled by
  other input, focus changes, grabs, locks, and session teardown.
- Ship the native ferese-rime user service, Rime defaults, installer
  inventory, package dependencies, session environment, and docs.
- Vendor Smithay 8a27023 with the SHM texture-cache format fix and add
  GPU regressions for format changes and resize snapshots.
- Release reused CRTC owners before staging output modes, then restore
  changed outputs before former owners when a transaction fails.
- Wait for resize-capture GPU completion, expand filtered surface
  damage, and preserve IME popup origin under fractional scaling.
- Mark weekends like holidays in both calendar layouts.

# Smithay Changelog
## Unreleased
### Breaking changes
`wayland::virtual_keyboard` no longer sends key events to focused clients on its
own. A virtual keyboard is now an regular input device:
`VirtualKeyboardManagerState::new` requires the state to implement the new
`VirtualKeyboardHandler`, which receives `InputEvent<VirtualKeyboardBackend>`s
for the compositor to handle like real devices (so special keys, compositor
bindings, idle handling and focus works properly). The compositor has to
activate the device's keymap (`VirtualKeyboardDevice::keymap`) before processing
its key events. Modifiers set with the `modifiers` request are not reset when
the device is destroyed (the masks are absolute, so that would also clear state
not set by the device, like locks set by other devices on a shared keymap). The
compositor is responsible for reconciling the modifier state on `DeviceRemoved`
(e.g., by tracking the bits set by it). `VirtualKeyboardUserData` is no longer
generic over the state type.
`crate::wayland::selection::data_device::start_dnd` was removed in favor of exposing the
underlying `DnDGrab` and associated types to make it possible to write external Drag&Drop sources
and targets (e.g. for other shell implementations). See the `Additions`-section for more info.
This also means the `ServerDndGrabHandler` was removed. The `ClientDndGrabHandler` was split into
a generic `DndGrabHandler` and a specific `WaylandDndGrabHandler`. `WaylandDndGrabHandler::started` needs to
be implemented and explicitly start a `DnDGrab` for wayland DnD-operations to work.
`X11WM::start_wm` now needs a `DisplayHandle`-reference and adds requirements for the State type to
implement `DndGrabHandler` and the `SeatHandler`s `PointerFocus` and `TouchFocus`-types to implement
the new `DndFocus` trait.
`GbmFramebufferExporter::new` now accepts a `NodeFilter` as import node, which
enables accepting dmabufs originating from any node.
```diff
-GbmFramebufferExporter::new(gbm, node);
+GbmFramebufferExporter::new(gbm, node.into());
-GbmFramebufferExporter::new(gbm, None);
+GbmFramebufferExporter::new(gbm, NodeFilter::None);
-GbmFramebufferExporter::new(gbm, Some(node));
+GbmFramebufferExporter::new(gbm, node.into());
+GbmFramebufferExporter::new(gbm, NodeFilter::All);
```
`DrmOutputManager` does now provide an explicit `lock`-method returning a [`LockedDrmOutputManager`].
All other methods have moved to this new type, allowing compositors to take the same lock across multiple
operations.
xdg_shell, layer_shell, and session_lock surfaces now track `last_acked` state for each commit.
You can find it in the `last_acked` field of the corresponding `...CachedState` structs.
The "current state" and "current serial" attribute fields were removed; use `last_acked` from the new `with_committed_state()` accessors instead (and verify that you didn't actually want `with_pending_state()` instead where you used the "current state").
```diff
-ToplevelSurface::current_state();
+ToplevelSurface::with_committed_state(|state| {
+ // ...
+});
-PopupSurface::current_state();
+PopupSurface::with_committed_state(|state| {
+ // ...
+});
-LayerSurface::current_state();
+LayerSurface::with_committed_state(|state| {
+ // ...
+});
-LockSurface::current_state();
+LockSurface::with_committed_state(|state| {
+ // ...
+});
struct XdgToplevelSurfaceRoleAttributes {
- configured: bool,
- configure_serial: Option<Serial>,
- current: ToplevelState,
- current_serial: Option<Serial>,
- last_acked: Option<ToplevelState>,
+ last_acked: Option<ToplevelConfigure>,
// ...
}
struct XdgPopupSurfaceRoleAttributes {
- configured: bool,
- configure_serial: Option<Serial>,
- current: PopupState,
- current_serial: Option<Serial>,
- committed: bool,
- last_acked: Option<PopupState>,
+ last_acked: Option<PopupConfigure>,
// ...
}
struct LayerSurfaceAttributes {
- configured: bool,
- configure_serial: Option<Serial>,
- current: LayerSurfaceState,
- last_acked: Option<LayerSurfaceState>,
+ last_acked: Option<LayerSurfaceConfigure>,
// ...
}
-impl Copy for LayerSurfaceCachedState;
```
The following methods are no longer needed as Smithay does them automatically now:
```diff
-ToplevelSurface::reset_initial_configure_sent();
-PopupSurface::reset_initial_configure_sent();
```
You also no longer need to manually set `LayerSurfaceAttributes::initial_configure_sent`, Smithay handles it automatically.
The `delegate_*!` macros have been replaced with a single `delegate_dispatch2!` macro, which implements dispatch in terms
of new `Dipsatch2` and `GlobalDispatch2` traits. These will replace `Dispatch` and `GlobalDispatch` in a future version of
`wayland_server`.
The `SpaceElement::geometry` impl for `X11Surface` is no longer equivalent to its bbox. For clients that set
`_GTK_FRAME_EXTENTS`, the shadow extents are subtracted from the bbox to give the geometry.
`X11Surface::geometry` has been renamed to `X11Surface::last_configure`. `X11Surface::geometry` now returns the bounding
box minus the surface's frame extents.
`SessionLockHandler::unlock` will no longer be called if the `ext_session_lock_v1` instance that sent the
`unlock_and_destroy` request is not the same instance as the one that successfully locked the session.
`SessionLockHandler::new_surface` can be called for multiple `SessionLocker` instances that could be in-flight at the same
time. `LockSurface::ext_session_lock` has been added to allow the compositor to disambiguate, and associate lock surfaces
with the correct lock instance.
`backend::input` and `input` now use `backend::input::InputTime` for timestamps instead of `u32` or `u64`. `InputTime::now()`
is used for timestamps for synthesized events.
`TextInputActivation` must be implemented. It allows for hooks to be run when a text input is `activated` and `deactivated`.
`KeyboardHandle::input_intercept()` now has a `source` argument and early-returns `None` when the key was already pressed/released, matching the behavior of `KeyboardHandle::input()`.
```diff
-let (res, mods_changed) = keyboard.input_intercept(data, keycode, state, filter);
+let Some((res, mods_changed)) = keyboard.input_intercept(
+ KeyboardSource::MAIN,
+ data,
+ keycode,
+ state,
+ filter,
+) else {
+ return;
+};
```
### Additions
- Add `WmWindowProperty::Other` to forward unrecognized X11 property changes to the compositor.
- The wlr virtual pointer protocol is now available in `smithay::wayland::virtual_pointer`.
- `Xkb::keymap_as_string` returns the active keymap as `XKB_KEYMAP_FORMAT_TEXT_V1`.
- `XkbContext::set_modifier_mask` applies raw xkb modifier masks to a keyboard
for clients that report modifier state directly instead of through key presses
(e.g., `zwp_virtual_keyboard_v1.modifiers`).
- `KeyboardHandle::input_forward_bypassing_grab` sends a key skipping the active
grab, which can be used by compositors to prevent infinite loops when a client
with a grab forwards a key through its own virtual keyboard, which can be
tracked with `InputMethodHandle::keyboard_grab_client` and
`VirtualKeyboardDevice::client`.
- `VirtualKeyboardDevice::source` gives each virtual keyboard its own
`KeyboardSource` so keys pressed on multiple devices are released when the
last one is released.
- ExtBackgroundEffect protocol is now available in `smithay::wayland::background_effect` module.
`crate::input::dnd` was introduced to enable implementation of Drag&Drop operations on custom types.
Internally the same types and traits are used to implement `wayland::data_device` dnd-operations and XDND
operations (see below).
`DnDGrab` is the new entry-point for DnD operations. It requires `SeatHandler::PointerFocus` or
`SeatHandler::TouchFocus` respectively to implement `DndFocus`, which is used to send events to
types, which can be targets of DnD operations. `Source` is a new trait for types that represent
sources of data for DnD operations.
`Source::accepted` is called when a target accepts a mime-type, or rejects the offer with `None`.
Sources that proxy an upstream offer need it: a nested compositor forwarding a drag to its own
clients only receives `drop` from the host compositor once it has itself accepted on the upstream
offer, and previously had no way to know when a nested client had done so. It has a default no-op
implementation, so sources that originate their own data are unaffected.
The Xwayland WM can now handle XDND operations and bridge them over to the new generic DnD interface
allowing DnD operations between X11 and Wayland clients (both directions).
`X11Surface` now has a new `surface_under`-method, which is also internally used by `SpaceElement::is_in_input_region` and `crate::desktop::Window::surface_under`. Any direct usage of `under_from_surface_tree` on the underlying `wl_surface` of an `X11Surface` should be replaced with this method for XDND to work correctly.
`X11Surface` now parses and exposes the Motif WM hints via `motif_hints()`.
`X11Wm` allows you to remove and clear XSETTINGS settings.
xdg_shell and layer_shell now enforce the client acking a configure before committing a buffer, as required by the protocols.
```rs
struct ToplevelCachedState {
/// Configure last acknowledged by the client at the time of the commit.
last_acked: Option<ToplevelConfigure>,
}
/// Provides access to the current committed cached state.
fn ToplevelSurface::with_cached_state<T>(&self, f: impl FnOnce(&ToplevelCachedState) -> T) -> T;
/// Provides access to the current committed state.
fn ToplevelSurface::with_committed_state<T>(&self, f: impl FnOnce(Option<&ToplevelState>) -> T) -> T;
struct PopupCachedState {
/// Configure last acknowledged by the client at the time of the commit.
last_acked: Option<ToplevelConfigure>,
}
/// Provides access to the current committed cached state.
fn PopupSurface::with_cached_state<T>(&self, f: impl FnOnce(&PopupCachedState) -> T) -> T;
/// Provides access to the current committed state.
fn PopupSurface::with_committed_state<T>(&self, f: impl FnOnce(Option<&PopupState>) -> T) -> T;
struct LayerSurfaceCachedState {
/// Configure last acknowledged by the client at the time of the commit.
last_acked: Option<LayerSurfaceConfigure>,
// ...
}
/// Provides access to the current committed cached state.
fn LayerSurface::with_cached_state<T>(&self, f: impl FnOnce(&LayerSurfaceCachedState) -> T) -> T;
/// Provides access to the current committed state.
fn LayerSurface::with_committed_state<T>(&self, f: impl FnOnce(Option<&LayerSurfaceState>) -> T) -> T;
struct LockSurfaceCachedState {
/// Configure last acknowledged by the client at the time of the commit.
last_acked: Option<LockSurfaceConfigure>,
}
/// Provides access to the current committed cached state.
fn LockSurface::with_cached_state<T>(&self, f: impl FnOnce(&LockSurfaceCachedState) -> T) -> T;
/// Provides access to the current committed state.
fn LockSurface::with_committed_state<T>(&self, f: impl FnOnce(Option<&LockSurfaceState>) -> T) -> T;
struct LockSurfaceAttributes {
server_pending: Option<LockSurfaceState>,
pending_configures: Vec<LockSurfaceConfigure>,
last_acked: Option<LockSurfaceConfigure>,
}
type LockSurfaceData = Mutex<LockSurfaceAttributes>;
struct LockSurfaceConfigure {
state: LockSurfaceState,
serial: Serial,
}
```
Added `Element::is_framebuffer_effect` and `RenderElement::capture_framebuffer` to better support render elements,
that take the current framebuffers contents and modify them, e.g. blurring the backgrounds of windows.
See the documentation for these functions for how to make use of them, but note, that they provide
default implementations, which result in skipping the new functionality. As such any custom `RenderElements` wrappers
(not using `crate::render_elements!`) need to be updated.
`Space` has new functionality that allows for more fine-grained control over window stacking:
- `map_element_above()`: maps a new element directly above an existing one.
- `raise_element_above()`: same as above, but moves an already-mapped element.
- `lower_element()`: lowers an element to the bottom of the stack, respecting its z-index group.
- `relocate_element()`: moves an element to a new location in the space without changing the stacking order.
`Output` now has `owns_xdg_output()` which allows you to match an XDG output protocol object with an `Output`.
Added `Renderer::invalidate_caches`, which unconditionally drops all renderer-internal caches,
including entries `Renderer::cleanup_texture_cache` retains while their source buffers are still
alive.
Added `GpuManager::cleanup_texture_cache` and `GpuManager::invalidate_caches`, which apply the
corresponding `Renderer` method to every enumerated device. `GpuManager::invalidate_caches`
additionally drops the buffers cached for copying between a render and a target node, which no
`Renderer` owns.
### Bugfixes
`input_method_v2`: a second input method binding a seat that already has one is now the object told
it is `unavailable`, per the protocol, leaving the existing instance in place. Previously the event
went to the existing instance and the newcomer was dropped untracked. Destroying such an inert
newcomer no longer clears the active instance, and its requests no longer drive the seat.
`DrmSurface::use_vrr(false)` now succeeds as a no-op when using legacy DRM. Attempts to enable VRR
on legacy DRM still return `UnknownProperty`.
The `xdg_toplevel` request handler now posts an `invalid_size` error when a client performs a `set_max_size` or `set_min_size` request with a negative width or height.
`DrmDeviceFd::new` no longer tries to become DRM master on a render node, which the kernel always
refuses, so it no longer warns about it.
`SimpleCrtcMapper` (in `smithay-drm-extras`) now releases the CRTC reservation of any connector that
is no longer connected, including connectors that have disappeared from the resource list entirely
rather than being reported as disconnected. Previously such connectors (for example DP-MST sink
connectors when a dock is unplugged, or across suspend/resume) leaked their CRTC reservation
indefinitely, which could accumulate until a newly connected output could no longer be assigned a
CRTC.
XWayland now honors WM_HINTS request to map the window in IconicState(minimized). Compositors should
check X11Surface::is_hidden() at mapping time and minimize the window appropriately.
Space::refresh() now clears stale outputs before emitting any enter events so no wl_surface.enter events
are emitted with a stale wl_output anymore.
The XWayland WM implementation previously incorrectly prefixed large transfers from X11 windows with
the four INCR bytes.
`MultiRenderer::cleanup_texture_cache` now also cleans up the devices other than the render and
target device. Buffers that cannot be imported on the render node directly are imported on their
source device, so those devices accumulate cached imports that previously were never released.
Cleanup is now also attempted on every device even if it fails on one of them, with every failure
logged and the first error returned.
`send_frames_surface_tree` (and `Window::send_frame`, `LayerSurface::send_frame`) no longer sends frame
callbacks to surfaces whose renderer state has no buffer, or to their subsurfaces.
`GlesRenderer::cleanup_texture_cache` and `GlesRenderer::invalidate_caches` now only make their EGL
context current when resources are queued for destruction. This avoids waking idle GPUs and
blocking the compositor while they resume.
`ext_image_copy_capture_session_v1` now raises the `duplicate_frame` protocol error when a client
calls `create_frame` while the session still has an active frame, as the protocol requires. Previously
the request was accepted and the extra frame was silently added to the session.
## 0.7.0
### Breaking changes
`DrmSyncobjHandler::drm_syncobj_state` is now Optional.
Whenever state is None `ImportTimeline` request will result in `InvalidTimeline` protocol error.
This allows one to destroy DrmSyncobjState by calling `DrmSyncobjState::into_global()`
```diff
-fn DrmSyncobjHandler::drm_syncobj_state(&mut self) -> &mut DrmSyncobjState
+fn DrmSyncobjHandler::drm_syncobj_state(&mut self) -> Option<&mut DrmSyncobjState>
```
`DrmTimeline` constructor now accepts OwnedFd:
```diff
-fn DrmTimeline::new(device: &DrmDeviceFd, fd: BorrowedFd<'_>) -> io::Result<Self>
+fn DrmTimeline::new(device: &DrmDeviceFd, fd: OwnedFd) -> io::Result<Self>
```
`DrmSyncPoint::eventfd` now returns `Arc<OwnedFd>`:
```diff
-fn DrmSyncPoint::eventfd(&self) -> io::Result<OwnedFd>
+fn DrmSyncPoint::eventfd(&self) -> io::Result<Arc<OwnedFd>>
```
`GbmFramebufferExporter` constructor now accepts `import_node`,
it will be used to filter DMA-BUFs to only those originating from a specific device before considering them for direct scanout.
If `import_node` is `None` direct-scanout of client-buffers won't be used.
```diff
-fn GbmFramebufferExporter::new(gbm: Device<A>) -> Self
+fn GbmFramebufferExporter::new(gbm: Device<A>, import_node: Option<DrmNode>) -> Self
```
### Additions
#### WeakDrmDeviceFd
```rs
/// Returns a weak reference to the underlying device
fn DrmDeviceFd::downgrade(&self) -> WeakDrmDeviceFd;
/// Construct an empty Weak reference, that will never upgrade successfully
fn WeakDrmDeviceFd::new() -> Self;
/// Try to upgrade to a strong reference
fn WeakDrmDeviceFd::upgrade(&self) -> Option<DrmDeviceFd>;
```
#### KeyboardHandle::set_modifier_state
```rs
/// Set the modifiers state.
fn KeyboardHandle::set_modifier_state(&self, mods_state: ModifiersState) -> u32;
/// Serialize modifier state back to be sent to xkb.
fn ModifiersState::serialize_back(&self, state: &xkb::State) -> SerializedMods;
```
#### XWaylandKeyboardGrab
```rs
/// Get the `zwp_xwayland_keyboard_grab_v1` object that created the grab
fn XWaylandKeyboardGrab::grab(&self) -> &ZwpXwaylandKeyboardGrabV1;
/// Grab is now cloneable
impl Clone for XWaylandKeyboardGrab;
```
#### X11Surface
```rs
/// Returns the hints for the underlying X11 window
fn X11Surface::hints(&self) -> Option<x11rb::properties::WmHints>;
/// Get the client PID associated with the X11 window.
fn X11Surface::get_client_pid(&self) -> Result<u32, Box<dyn Error>>;
```
#### DrmSyncobjState
```rs
/// Destroys the state and returns the `GlobalId` for compositors to disable/destroy.
fn DrmSyncobjState::into_global(self) -> GlobalId;
/// Sets a new `import_device` to import the syncobj fds and wait on them.
fn DrmSyncobjState::update_device(&mut self, import_device: DrmDeviceFd);
```
#### xdg-toplevel-tag-v1
XdgToplevelTag protocol is now available in `smithay::wayland::xdg_toplevel_tag` module.
#### cursor-shape-v1
CursorShape is now updated to version `2`
## 0.6.0
### Breaking Changes
`RenderContext::draw` callback now accepts a mutable reference
```diff
-fn smithay::backend::renderer::element::texture::RenderContext::draw(&mut self, f: impl FnOnce(&T))
+fn smithay::backend::renderer::element::texture::RenderContext::draw(&mut self, f: impl FnOnce(&mut T))
```
Framebuffer now requires `Texture` implementation
```rs
type smithay::backend::renderer::RendererSuper::Framebuffer: smithay::backend::renderer::Texture
```
`Output::client_outputs` no longer returns a Vec
```diff
-fn smithay::output::Output::client_outputs(&self, client: &Client) -> Vec<WlOutput>;
+fn smithay::output::Output::client_outputs(&self, client: &Client) -> impl Iterator<Item = WlOutput>;
```
DamageBag/DamageSnapshot damage getters got renamed
```diff
-fn smithay::backend::renderer::utils::DamageBag::damage(&self) -> impl Iterator<Item = impl Iterator<Item = &Rectangle>>
+fn smithay::backend::renderer::utils::DamageBag::raw(&self) -> impl Iterator<Item = impl Iterator<Item = &Rectangle>>
-fn smithay::backend::renderer::utils::DamageSnapshot::damage(&self) -> impl Iterator<Item = impl Iterator<Item = &Rectangle>>
+fn smithay::backend::renderer::utils::DamageSnapshot::raw(&self) -> impl Iterator<Item = impl Iterator<Item = &Rectangle>>
```
RendererSurfaceState::damage now returns a DamageSnapshot
```diff
-fn smithay::backend::renderer::utils::RendererSurfaceState::damage(&self) -> impl core::iter::traits::iterator::Iterator<Item = impl core::iter::traits::iterator::Iterator<Item = &smithay::utils::Rectangle<i32, smithay::utils::Buffer>>>
+fn smithay::backend::renderer::utils::RendererSurfaceState::damage(&self) -> smithay::backend::renderer::utils::DamageSnapshot<i32, smithay::utils::Buffer>
```
Client scale can now be fractional
```diff
-fn smithay::wayland::compositor::CompositorClientState::client_scale(&self) -> u32
+fn smithay::wayland::compositor::CompositorClientState::client_scale(&self) -> f64
-fn smithay::wayland::compositor::CompositorClientState::set_client_scale(&self, new_scale: u32)
+fn smithay::wayland::compositor::CompositorClientState::set_client_scale(&self, new_scale: f64)
```
Raw `renderer_id` got replaced with new `smithay::backend::renderer::ContextId` newtype
```diff
-fn smithay::backend::renderer::gles::GlesFrame::id(&self) -> usize;
+fn smithay::backend::renderer::gles::GlesFrame::context_id(&self) -> ContextId;
-fn smithay::backend::renderer::gles::GlesRenderer::id(&self) -> usize;

+fn smithay::backend::renderer::utils::RendererSurfaceState::texture<R>(&self, id: &ContextId) -> Option<&TextureId>;
```
`CursorShapeDeviceUserData` now has an additional generic argument
```diff
-struct smithay::wayland::cursor_shape::CursorShapeDeviceUserData;
+struct smithay::wayland::cursor_shape::CursorShapeDeviceUserData<D: SeatHandler>;
```
The explicit frame buffers got introduced, but for the sake of my sanity those changes are not described here, you can look at: https://github.com/Smithay/smithay/commit/df08c6f29eb6ebfa2fce6fc374590483bcbaf21a
### API Additions
It is now possible to check if the OpenGL context is shared with another.

```
It is now possible to check that there are no other references to the underlying GL texture.
```rs
fn smithay::backend::renderer::gles::GlesTexture::is_unique_reference();
```
There is a new gles capability for support of fencing and exporting to EGL
```rs
smithay::backend::renderer::gles::Capability::ExportFence;
```
There is a new BlitFrame trait for frames that support blitting contents from/to the current framebuffer to/from another.
```rs
trait smithay::backend::renderer::BlitFrame;
impl BlitFrame for smithay::backend::renderer::gles::GlesFrame;
impl BlitFrame for smithay::backend::renderer::glow::GlowFrame;
impl BlitFrame for smithay::backend::renderer::multigpu::MultiFrame;
```
It is now possible to iterate over all known tokens and their associated data
```rs
fn smithay::wayland::xdg_activation::XdgActivationState::tokens() -> impl Iterator<Item = (&XdgActivationToken, &XdgActivationTokenData)>;
```
There are new errors for missing DRM crtc/connector/plane mapping
```rs
smithay::backend::drm::DrmError::{UnknownConnector, UnknownCrtc, UnknownPlane};
```
Texture has a few new implementations
```rs
impl Texture for smithay::backend::renderer::gles::GlesTarget;
impl Texture for smithay::backend::renderer::multigpu:MultiFramebuffer;
impl Texture for smithay::backend::renderer::pixman::PixmanTarget;

```
It is now possible to access WlKeyboard/WlPointer instances
```rs
fn smithay::input::keyboard::KeyboardHandle::client_keyboards(&self, client: &Client) -> impl Iterator<Item = WlKeyboard>;
fn smithay::input::pointer::PointerHandle::client_pointers(&self, client: &:Client) -> impl Iterator<Item = WlPointer>;
```
New APIs for X11 randr output management
```rs
enum smithay::xwayland::xwm::PrimaryOutputError { OutputUnknown, X11Error(x11rb::errors::ReplyError) };
impl From<x11rb::errors::ConnectionError> for smithay::xwayland::xwm::PrimaryOutputError;
fn smithay::xwayland::xwm::PrimaryOutputError::from(value: x11rb::errors::ConnectionError) -> Self;
fn smithay::xwayland::xwm::X11Wm::get_randr_primary_output(&self) -> Result<Option<String>, x11rb::errors::ReplyError>;
fn smithay::xwayland::xwm::X11Wm::set_randr_primary_output(&mut self, output: Option<&smithay::output::Output>) -> Result<(), smithay::xwayland::xwm::PrimaryOutputError>;
fn smithay::xwayland::xwm::XwmHandler::randr_primary_output_change(&mut self, xwm: smithay::xwayland::xwm::XwmId, output_name: Option<String>);
```
It is now possible to get the DrmNode of the device the buffer was allocated on
```rs
fn smithay::backend::allocator::gbm::GbmBuffer::device_node(&self) -> Option<drm::node::DrmNode>;
```
It is now possible to create a `GbmBuffer` from an existing `BufferObject` explicitly defining the device node
```rs
fn smithay::backend::allocator::gbm::GbmBuffer::from_bo_with_node(bo: gbm::buffer_object::BufferObject<()>, implicit: bool, drm_node: core::option::Option<drm::node::DrmNode>) -> Self;
```
It is now possible to access the `Allocator` of this output manager
```rs
fn smithay::backend::drm::output::DrmOutputManager::allocator(&self) -> &Allocator;
```
Is is now possible to check if EGLDevice is backed by actual device node or is it a software device.
```rs
fn smithay::backend::egl::EGLDevice::is_software(&self) -> bool
```
This adds a way to query next deadline of a commit timing barrier.
Allows a compositor to schedule re-evaluating commit timers without
busy looping.
```rs
fn smithay::wayland::commit_timing::CommitTimerBarrierState::next_deadline(&self) -> Option<smithay::wayland::commit_timing::Timestamp>;
```
Support for casting `Timestamp` back to `Time`
This might be useful to compare the next deadline with a monotonic time
from the presentation clock
```rs
impl From<smithay::wayland::commit_timing::Timestamp> for smithay::utils::Time;
```
Support for creating a weak reference to a `Seat`
```rs
fn smithay::input::Seat::downgrade(&self) -> smithay::input::WeakSeat;
fn smithay::input::WeakSeat::is_alive(&self) -> bool;
pub fn smithay::input::WeakSeat::upgrade(&self) -> Option<smithay::input::Seat>;
```

## 0.4.0
### Breaking Changes
**`wayland-server` was updated to 0.30:**
- Most of the wayland frontend API is changed to follow the new request dispatching mechanism built around the `Dispatch` trait from `wayland-server`
- Modules that provide handlers for Wayland globals now provide `DelegateDispatch` implementations, as well as macros to simplify the dispatching from your main state
#### Clients & Protocols
- Remove `xdg-shell-unstable-v6` backwards compatibility
- `XdgPositionerState` moved to `XdgPopupState` and added to `XdgRequest::NewPopup`
- `PopupSurface::send_configure` now checks the protocol version and returns an `Result`
- `KeyboardHandle::input` filter closure now receives a `KeysymHandle` instead of a `Keysym` and returns a `FilterResult`.
- `PointerButtonEvent::button` now returns an `Option<MouseButton>`.
- `MouseButton` is now non-exhaustive.
- Remove `Other` and add `Forward` and `Back` variants to `MouseButton`. Use the new `PointerButtonEvent::button_code` in place of `Other`.
- `GrabStartData` has been renamed to `PointerGrabStartData`
- The `slot` method on touch events no longer returns an `Option` and multi-touch capability is thus opaque to the compositor
- `wayland::output::Output` now is created separately from it's `Global` as reflected by [`Output::new`] and the new [`Output::create_global] method.
- `PointerHandle` no longer sends an implicit motion event when a grab is set, `time` has been replaced by an explicit `focus` parameter in [`PointerHandle::set_grab`]
- `ToplevelSurface::send_configure`/`PopupSurface::send_configure`/`LayerSurface::send_configure` now always send a configure event regardless of changes and return
the serial of the configure event. `send_pending_configure` can be used to only send a configure event on pending changes.
#### Backends
- Rename `WinitInputBacked` to `WinitEventLoop`.
- Rename `WinitInputError` to `WinitError`;
- `WinitInputBackend` no longer implements `InputBackend`. Input events are now received from the `WinitEvent::Input` variant.
- All winit backend internal event types now use `WinitInput` as the backend type.
- `WinitEventLoop::dispatch_new_events` is now used to receive some `WinitEvent`s.
- Added `TabletToolType::Unknown` as an option for tablet events
- `render_texture` was removed from `Frame`, use `render_texture_at` or `render_texture_from_to` instead or use `Gles2Renderer::render_texture` as a direct replacement.
- Remove `InputBackend::dispatch_new_events`, turning `InputBackend` into a definition of backend event types. Future input backends should be a `calloop::EventSource`.
- Remove `InputBackend::EventError` associated type as it is unneeded since `dispatch_new_events` was removed.
- `Swapchain` does not have a generic Userdata-parameter anymore, but utilizes `UserDataMap` instead
- `GbmBufferedSurface::next_buffer` now additionally returns the age of the buffer
- `Present` was merged into the `X11Surface`
- `X11Surface::buffer` now additionally returns the age of the buffer
- `X11Surface` now has an explicit `submit` function
- `X11Surface` is now multi-window capable.
- `Renderer::clear` now expects a second argument to optionally only clear parts of the buffer/surface
- `Transform::transform_size` now takes a `Size` instead of two `u32`
- `Gles2Renderer` now automatically flips the `render` result to account for OpenGLs coordinate system
- `Frame::clear`, `Frame::render_texture_at` and `Frame::render_texture_from_to` now have an additional damage argument
- `EGLNativeSurface` implementations overriding `swap_buffers` now receive and additional `damage` attribute to be used with `eglSwapBuffersWithDamageEXT` if desired
- `EGLSurface::swap_buffers` now accepts an optional `damage` parameter
- `WinitGraphicsBackend` does no longer provide a `render`-method and exposes its `Renderer` directly instead including new functions `bind` and `submit` to handle swapping buffers.
- `ImportShm` was renamed to `ImportMem`
- `ImportMem` and `ImportDma` were split and do now have accompanying traits `ImportMemWl` and `ImportDmaWl` to import wayland buffers.
- Added `EGLSurface::get_size`
- `EGLDisplay::get_extensions` was renamed to `extensions` and now returns a `&[String]`.
- Added gesture input events, which are supported with the libinput backend.
### Additions
#### Clients & Protocols
- `xdg_activation_v1` support
- `wlr-layer-shell-unstable-v1` support

- Setting the parent of a toplevel surface is now possible with the `xdg::ToplevelSurface::set_parent` function.
- Add support for the zxdg-foreign-v2 protocol.
- Support for `xdg_wm_base` protocol version 3

- Added a `KeyboardGrab` similar to the existing `PointerGrab`
- `wayland::output::Output` now has a `current_scale` method to quickly retrieve its set scale.
- `wayland::shell::wlr_layer::KeyboardInteractivity` now implements `PartialEq` and `Eq`.

#### Backends
- New `x11` backend to run the compositor as an X11 client. Enabled through the `backend_x11` feature.
- `x11rb` event source integration used in anvil's XWayland implementation is now part of smithay at `utils::x11rb`. Enabled through the `x11rb_event_source` feature.
- `KeyState`, `MouseButton`, `ButtonState` and `Axis` in `backend::input` now derive `Hash`.
- New `DrmNode` type in drm backend. This is primarily for use a backend which needs to run as client inside another session.
- The button code for a `PointerButtonEvent` may now be obtained using `PointerButtonEvent::button_code`.
- `Renderer` now allows texture filtering methods to be set.
- `backend::renderer` has a new `utils`-module that can take care of client buffer management for you.
- `EGLSurface::buffer_age` can be used to query the surface buffer age.

- Added `ExportDma` trait to export framebuffers and textures into dmabufs
- Added `ExportMem` trait to copy framebuffers and textures into memory
- Added `multigpu`-module to the renderer, which makes handling multi-gpu setups easier!
- Added `backend::renderer::utils::import_surface_tree` to be able to import buffers before rendering
- Added `EGLContext::display` to allow getting the underlying display of some context.
- Make `EGLContext::dmabuf_render_formats` and `EGLContext::dmabuf_texture_formats` also accessible from `EGLDisplay`.
#### Desktop
- New `desktop` module to handle window placement, tracks popups, layer surface and various rendering helpers including automatic damage-tracking! (+so much more)
#### Utils
- `Rectangle` can now also be converted from f64 to i32 variants
- `Rectangle::contains_rect` can be used to check if a rectangle is contained within another
- `Coordinate` is now part of the public api, so it can be used for coordinate agnositic functions outside of the utils module or even out-of-tree

- Only toplevel surfaces now get implicit keyboard focus
- Fix popup drawing for fullscreen windows
## version 0.3.0 (2021-07-25)
Large parts of Smithay were changed with numerous API changes. It is thus recommended to
approach version 0.3 as if it was a new crate altogether compared to 0.2.
The most notable changes are:
- Deep refactor of the graphics backends around a workflows centered on allocating graphics buffers,
and a Gles2-based renderer abstraction is provided.
- Support for DRM atomic modesetting as well as client-provided DMABUF
- Most backends are now `calloop` event sources generating events. The recommended organization for
your smithay-based compositor is thus to centralize most of your logic on a global state struct,
and delegate event handling to it via the shared data mechanism of `calloop`. Most of the callbacks
you provide to Smithay are given mutable access to this shared data.
- The `wayland::compositor` handling logic now automatically handles state tracking and delayed commit
for wayland surfaces.
Many thanks to the new contributors to Smithay, who contributed the following:
- Support for [`libseat`](https://sr.ht/~kennylevinsen/seatd/) as a session backend, by
@PolyMeilex
- Support for graphics tablets via the `tablet` protocol extension, by @PolyMeilex
- Support for running Smithay on `aarch64` architectures, by @cmeissl
- A rework of the `xdg-shell` handlers to better fit the protocol logic and correctly track configure
events, by @cmeissl
- Basic Xwayland support, by @psychon
