wayland-backend

• client: Put ObjectId::display_ptr behind libwayland_client_1_23 feature
  • Breaking change to fix issue with release

Additions

• client: Added display_ptr method to ObjectId
• server: Addded Handle::global_name
  • Requires libwayland_server_1_22 feature
• client: Added set_max_buffer_size method
• server: Added set_default_max_buffer_size and set_client_max_buffer_size methods

Bugfixes

• backend/server/rs: Send protocol error if method requires newer protocol version

Changes

• backend/client/rs: Unbounded buffering, matching libwayland behavior

Additions

• backend: Added a destroy_object method
• backend/server: Remove registry from known_registries if destructor is called

Bugfixes

• Freeze when dispatching within the queue dispatch on the same thread with system lib

Bugfixes

• backend/sys: Prevent send_request being called in parallel with dispatch_pending

Additions

• backend/client_sys: ReadEventsGuard::read_without_dispatch for just reading the events without dispatch

Bugfixes

• backend/rs: Prevent a potential deadlock during client cleanup

Bugfixes

• backend/sys: Fix importing external objects with Backend::manage_object by associating the proxy with the correct event queue

Bugfixes

• backend/rs: server: Fixed potential deadlock on object destruction

Additions

• Backend::manage_object for handling foreign proxies with the sys backend

Bugfixes

• backend/rs: server: Fixed potential deadlock caused by dead clients
• backend/sys: client dispatching now always uses distinct event queue

Additions

• Add rwh_06 feature for raw-window-handle 0.6

Bugfixes

• backend/rs: WAYLAND_DEBUG now displays fixed as decimal, not integer.
  • Matches libwayland

Additions

• client: Implement Eq for Backend

Bugfixes

• backend/sys: Fix error/segfault if object argument is no longer alive
• backend/rs: Retry send/recv on EINTR
  • Matches the behavior of libwayland

Bugfixes

• server/sys: Fix an issue where the backend could deadlock in some cases when sending an event that destroys an object.

Additions

• client: Add Backend::poll_fd to return fd for polling

Breaking change

• MSRV bumped to 1.65
• io-lifetimes is no longer a (public) dependency
• The Backend::prepare_read() method now returns None if the inner queue of the backend needs to be dispatched using Backend::dispatch_inner_queue(), instead of trying to dispatch it by itself. This can only happen when using the sys backend, and allows the crate to behave properly when multiple threads try to read the socket using the libwayland API.
• server: ObjectData::destroyed function signature has changed to pass the Handle and self as Arc<Self>.

Additions

• Add flush method to server Handle.

Bugfixes

• Setting WAYLAND_DEBUG server-side now properly prints incoming requests

Breaking changes

• Update wayland-sys to 0.31

Bugfixes

• In rust backend, retry read if message is incomplete, instead of Malformed error.

Breaking changes

• Message is now also generic on the Fd type, and io_lifetimes::OwnedFd is used instead of RawFd when appropriate.

Bugfixes

• The rust backend no longer ever does a blocking flush.
• Server-side sys backend is now able to track liveness of external objects.

Breaking changes

• all backends: creating null ObjectId is now done through the ObjectId::null() method, and the null_id() methods on the backends are removed.
• Argument::Str now contains an Option, which is correctly mapped to nullable strings. This fixes segfaults that previously occurred dereferencing the null pointer in the system backend.
• server: disable_global and remove_global now require the state type parameter, like create_global. This is required for compatibility with libwayland 1.21.
• ArgumentType::Array and ArgumentType::NewId no longer take a AllowNull and are never nullable.

Additions

• client: introduce Backend::dispatch_inner_queue() meant for ensuring a system backend in guest mode can still process events event it does not control reading the socket.
• introduce the log cargo feature to control logging behavior
• A dummy implementation of ClientData is now provided through () and all trait methods are optional

Bugfixes

• backend/sys: the inner lock is no longer held when destructors are invoked
• backend/sys: sys backend does not abort process when Backend::disable_global is invoked more than once

Additions

• client: ObjectId now implements the Hash trait
• server: ObjectId, ClientId and GlobalId now implement the Hash trait

Bugfixes

• backend/sys: the inner lock is no longer held when destructors are invoked

Additions

• client/sys: introduce Backend::from_foreign_display

Bugfixes

• The server backend now correctly associates interfaces with its object arguments when parsing messages with nullable object arguments.

Bugfixes

• server-rs: the inner lock is no longer help when destructors are invoked

Bugfixes

• server-sys: Skip unmanaged globals in the global filter (caused a segfault)

Breaking changes

• server-sys: move display_ptr() from Backend to Handle.

Breaking changes

• Both client and server APIs have been profoundly reworked. The backend now has internal locking mechanism allowing handles to it to be cloned and shared accross the application.

Bugfixes

• Fix a crash when exactly filling the internal buffers.

Bugfixes

• Client-side with the rust backend, wl_display events are now properly printed with other events when WAYLAND_DEBUG=1 is set.

Changes

• Server-side, request callbacks are now allowed to omit providing an ObjectData for newly created objects if they triggered a protocol error

Bugfixes

• Fix display leaks on system server backend.
• Fix a panic when trying to send a message with a null object argument followed by a non-null object argument
• Fix various memory leaks

• Expose wl_display pointer on system server backend

Breaking changes

• Server-side ObjectData::destroyed() now has access to the &mut D server-wide data.

Additions

• Introduce WEnum::into_result as a convenience method.

Initial pre-release of the crate.
