# Change Log
## Unreleased
## 0.7.2 -- 2021-02-09
#### Changes
- `EventLoop::run()` now accepts `Into<Option<Duration>>`, like `EventLoop::dispatch()`
#### Bugfixes
- The `Ping` event source now automatically disables itself when its sending end is
dropped, preventing to always be considered readable (which caused a busy-loop).
This also fixes a similar behavior of `Executor` and `Channel`, which use `Ping`
internally.
## 0.7.0 -- 2020-10-13
#### Breaking Changes
- The return type for `LoopHandle::insert_source` was renamed as
`RegistrationToken` and can be used in `{enable,disable,update,remove,kill}`
just like before.
- Allow non-`'static` event sources and callbacks, so they can hold references
to other values.
- `LoopHandle::with_source` was removed. To achieve the same behaviour, use a
`Dispatcher` and register it via the `LoopHandle::register_dispatcher`. The
`EventSource` will be available using `Dispatcher::as_source_{ref,mut}`.
- `LoopHandle::remove` doesn't return the event source any more. To achieve
the same behaviour, use a `Dispatcher` and register it via the
`LoopHandle::register_dispatcher`. After removing the `EventSource` with
`LoopHandle::remove`, you will be able to call
`Dispatcher::into_source_inner` to get ownership of the `EventSource`.
- `LoopHandle::register_dispatcher` can be used in place of
`LoopHandle::insert_source` when the source needs to be accessed after
its insertion in the loop.
- `Interest` is changed into a struct to allow empty interest queries
#### Additions
- Introduce a futures executor as a new event source, behind the `executor` cargo
feature.
- Introduce the `LoopHandle::adapt_io` method for creating `Async<F>` adapters to
adapt IO objects for async use, powered by the event loop.
## 0.6.5 -- 2020-10-07
#### Fixes
- Channel now signals readinnes after the event has actually been sent, fixing a race
condition where the event loop would try to read the message before it has been
written.
## 0.6.4 -- 2020-08-30
#### Fixes
- Fix double borrow during dispatch when some event source is getting removed
## 0.6.3 -- 2020-08-27
#### Aditions
- Add support for `openbsd`, `netbsd`, and `dragonfly`.
- `InsertError<E>` now implements `std::error::Error`.
#### Changes
- Allow non-`'static` dispatch `Data`. `Data` is passed as an argument to the
`callback`s while dispatching. This change allows defining `Data` types which
can hold references to other values.
- `dispatch` now will retry on `EINTR`.
## 0.6.2 -- 2020-04-23
- Update the README and keywords for crates.io
## 0.6.1 -- 2020-04-22
- Introduce `LoopHandle::kill` to allow dropping a source from within its callback
## 0.6.0 -- 2020-04-22
- Drop the `mio` dependency
- **Breaking Change**: Significantly rework the `calloop` API, notably:
- Event sources are now owned by the `EventLoop`
- Users can now again set the polling mode (Level/Edge/OneShot)
- Introduce the `Ping` event source
## 0.5.2 -- 2020-04-14
- `channel::Channel` is now `Send`, allowing you to create a channel in one thread and sending
its receiving end to an other thread for event loop insertion.
## 0.5.1 -- 2020-03-14
- Update `mio` to `0.7`
## 0.5.0 -- 2020-02-07
- Update to 2018 edition
- Update `nix` dependency to `0.17`
- **Breaking** Update `mio` dependency to `0.7.0-alpha.1`. The API of `calloop` for custom
event sources significantly changed, and the channel and timer event sources are now
implemented in `calloop` rather than pulled from `mio-extras`.
## 0.4.4 -- 2019-06-13
- Update `nix` dependency to `0.14`
## 0.4.3 -- 2019-02-17
- Update `mio` dependency
- Update `nix` dependency
## 0.4.2 -- 2018-11-15
- Implement `Debug` for `InsertError`.
## 0.4.1 -- 2018-11-14
- Disable the `sources::signal` module on FreeBSD so that the library can be built on this
platform.
## 0.4.0 -- 2018-11-04
- **Breaking** Use `mio-extras` instead of `mio-more` which is not maintained.
- **Breaking** Reexport `mio` rather than selectively re-exporting some of its types.
- Add methods to `Generic` to retrive the inner `Rc` and construct it from an `Rc`
- **Breaking** `LoopHandle::insert_source` now allows to retrieve the source on error.
## 0.3.2 -- 2018-09-25
- Fix the contents of `EventedRawFd` which was erroneously not public.
## 0.3.1 -- 2018-09-25
- introduce `EventedRawFd` as a special case for the `Generic` event source, for when
you really have to manipulate raw fds
- Don't panic when the removal of an event source trigger the removal of an other one
## 0.3.0 -- 2018-09-10
- Fixed a bug where inserting an event source from within a callback caused a panic.
- **[breaking]** Erase the `Data` type parameter from `Source` and `Idle`, for
improved ergonomics.
## 0.2.2 -- 2018-09-10
- Introduce an `EventLoop::run` method, as well as the `LoopSignal` handle allowing to
wakeup or stop the event loop from anywhere.
## 0.2.1 -- 2018-09-01
- Use `FnOnce` for insertion in idle callbacks.
## 0.2.0 -- 2018-08-30
- **[breaking]** Add a `&mut shared_data` argument to `EventLoop::dispatch(..)` to share data
between callbacks.
## 0.1.1 -- 2018-08-29
- `Generic` event source for wrapping arbitrary `Evented` types
- timer event sources
- UNIX signal event sources
- channel event sources
## 0.1.0 -- 2018-08-24
Initial release
