wayland-client

Backport from master.

Additions

• Updated Wayland core protocol to 1.26

• Updated Wayland core protocol to 1.25

Additions

• Add GlobalList::destroy to destroy registry with wl_fixes

Additions

• Add system and dlopen features, enabling wayland-backend features
• Add Connection::set_max_buffer_size

• Updated Wayland core protocol to 1.24

• Updated Wayland core protocol to 1.23

Additions

• Implement Eq for Connection

Bugfixes

• Fix a possible deadlock in EventQueue::blocking_dispatch()

Additions

• Implement AsFd for Connection and EventQueue so they can easily be used in a calloop source.

Breaking changes

• Bump bitflags to 2.0
• Updated wayland-backend to 0.3
• Calloop integration is now removed, to avoid tying wayland-client to it you can use the calloop-wayland-source crate instead
• Use BorrowedFd<'_> arguments instead of RawFd

Additions

• Introduce WaylandSource, an adapter to insert an EventQueue into a calloop EventLoop, hidden under the new calloop cargo feature

Bugfixes

• Weak::upgrade now checks if the object has been destroyed

Additions

• Support absolute paths in WAYLAND_DISPLAY
• Introduce Weak, a helper type to store proxies without risking reference cycles
• Introduce Proxy::is_alive() method checking if the protocol object referenced by a proxy is still alive in the protocol state.

Bugfixes

• Fix EventQueue::blocking_dispatch() not flushing the connection as it should
• Ensure that XDG_RUNTIME_DIR is an absolute path before trying to use it

Breaking changes

• Requests that create new objects now produce inert proxies when called on objects with invalid IDs instead of failing with InvalidId. This matches the behavior of non-object-creating requests (which also ignore the error).

• Connection::blocking_dispatch has been removed; use EventQueue::blocking_dispatch.

Additions

• QueueFreezeGuard for avoiding race conditions while constructing objects.

Breaking changes

• Connection::null_id() has been removed, instead use ObjectId::null().
• EventQueue::sync_roundtrip() has been renamed to EventQueue::roundtrip().
• Module globals has been removed as the abstractions it provide are not deemed useful.
• The trait DelegateDispatch as been removed, its functionnality being fused into a more generic version of the Dispatch trait.

Additions

• Introduce the log cargo feature to control logging behavior

• Introduce EventQueue::poll_dispatch_pending for running dispatch using an async runtime.

Breaking changes

• Large rework of the API as a consequence of the rework of the backend.

Breaking changes

• The DelegateDispatch mechanism is changed around an explicit trait-base extraction of module state from the main app state.

• Introduce conversion methods between wayland_backend::Handle and ConnectionHandle

Full rework of the crate, which is now organized around a trait-based Dispatch metchanism.

This can effectively be considered a new crate altogether.
