# CHANGELOG: wayland-backend
## Unreleased
## 0.1.2 -- 19/04/2023
#### Bugfixes
- In the rust server backend, don't send `delete_id` messages for server-created objects.
- In the system server backend, wakeup the event loop if there are pending destructors waiting
to be precessed.
## 0.1.1 -- 16/02/2023
#### Bugfixes
- In sys backend, fix global data not being cleaned up on display drop.
## 0.1.0 -- 27/12/2022
## 0.1.0-beta.14
#### Bugfixes
- In rust backend, retry read if message is incomplete, instead of `Malformed` error.
## 0.1.0-beta.10
#### 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.
## 0.1.0-beta.8
#### 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
## 0.1.0-beta.7
#### 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
## 0.1.0-beta.6
#### 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
## 0.1.0-beta.5
#### 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.
## 0.1.0-beta.4
#### Bugfixes
- server-rs: the inner lock is no longer help when destructors are invoked
## 0.1.0-beta.3
#### Bugfixes
- server-sys: Skip unmanaged globals in the global filter (caused a segfault)
## 0.1.0-beta.2
#### Breaking changes
- server-sys: move `display_ptr()` from `Backend` to `Handle`.
## 0.1.0-beta.1
#### 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.
## 0.1.0-alpha7
#### Bugfixes
- Client-side with the rust backend, `wl_display` events are now properly printed with other events
when `WAYLAND_DEBUG=1` is set.
## 0.1.0-alpha6
#### 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
## 0.1.0-alpha5
- Expose `wl_display` pointer on system server backend
## 0.1.0-alpha4
#### Breaking changes
- Server-side `ObjectData::destroyed()` now has access to the `&mut D` server-wide data.
## 0.1.0-alpha3
#### Additions
- Introduce `WEnum::into_result` as a convenience method.
## 0.1.0-alpha2
## 0.1.0-alpha1
Initial pre-release of the crate.
