Smithay Changelog

Unreleased

Breaking Changes

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.

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 WinitEvents.
• 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.

Additions

Clients & Protocols

• xdg_activation_v1 support
• wlr-layer-shell-unstable-v1 support
• Added public api constants for the roles of wl_shell_surface, zxdg_toplevel and xdg_toplevel. See the shell::legacy and shell::xdg modules for these constants.
• Whether a surface is toplevel equivalent can be determined with the new function shell::is_toplevel_equivalent.
• 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 the option to initialize the dmabuf global with a client filter

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.

Bugfixes

Clients & Protocols

• Multicache::has() now correctly does what is expected of it
• xdg_shell had an issue where it was possible that configured state gets overwritten before it was acked/committed.
• wl_keyboard rewind the keymap file before passing it to the client

Backends

• EGLBufferReader now checks if buffers are alive before using them.
• LibSeat no longer panics on seat disable event.

Anvil

• Anvil now implements the x11 backend in smithay. Run by passing --x11 into the arguments when launching.
• Passing ANVIL_MUTEX_LOG in environment variables now uses the slower Mutex logging drain.

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 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
