Change Log

Unreleased

0.13.0 -- 2024-02-25

Breaking changes

• Bump nix to v0.28. As nix is exposed in the public API, this is a breaking change. (#176)

Bugfixes

• Fix a panic that would occur when a task is scheduled in an event callback. (#172)

0.12.4 -- 2024-01-15

Additions

• calloop is now supported for Windows. (#168)
• Add the signals feature to docs.rs. (#166)

Bugfixes

• Fix a borrow error that can occur while using the executor. (#165)

0.12.3 -- 2023-10-10

Additions

• Token and RegistrationToken are now invalidated when the event source they represent is removed from the event loop.
• Implement AsRawFd and AsFd for EventLoop<'l, Data>

Bugfixes

• Fix an issue, where id-reuse could execute a PostAction on a newly registered event source

0.12.2 -- 2023-09-25

Bugfixes

• Fix an issue where the Generic event source would try to unregister its contents from the event loop after a failed registration.
• Fix an issue where the EventLoop would panic when processing a PostAction::Remove from an event source with subsources.

0.12.1 -- 2023-09-19

Bugfixes

• Fix EventSource::before_handle_events() being erroneously give an iterator over synthetic events instead of real events

0.12.0 -- 2023-09-11

Breaking changes

• Bump MSRV to 1.63
• Make signals an optional feature under the signals features.
• Replace the nix crate with standard library I/O errors and the rustix crate.
• pre_run and post_run on EventSource have been replaced with before_sleep and before_handle_events, respectively. These are now opt-in through the NEEDS_EXTRA_LIFECYCLE_EVENTS associated constant, and occur at slightly different times to the methods they are replacing. This allows greater compatibility with Wayland based event sources.

0.11.0 -- 2023-06-05

Bugfixes

• Fixed a crash due to double borrow when handling pre/post run hooks
• Fixes a panic that can occur when large Durations are passed to Timer::from_duration.
• Replace the sys module with the polling crate.

Additions

• With the block_on feature enabled, the EventLoop method now has a block_on method that runs a future to completion on the event loop.

Breaking changes

• Bump MSRV to 1.56
• Breaking: The TransientSource is now an opaque type. It provides API methods for removing or replacing the wrapped source. This mitigates a potential leak of registration data if the TransientSource is replaced by direct assignment in a parent source.
• Breaking: Timer::current_deadline returns Option<Instant>, so that it can return None in the event of an overflow.
• Breaking: Use AsFd instead of AsRawFd/RawFd.

0.10.2 -- 2022-11-08

Bugfixes

• The return value of LoopHandle::insert_idle no longer borrows the LoopHandle.

0.10.1 -- 2022-06-20

Additions

• The Channel now has proxy methods for Receiver::recv and Receiver::try_recv
• Enable support for target_os = "android"

0.10.0 -- 2022-05-06

• Breaking: Calloop's internal storage is now backed by a slotmap. As a result the RegistrationToken is now Copy+Clone, and the low-level registration API of Poll is altered in a breaking way. MSRV is bumped to 1.49.
• Breaking: generic::Fd adapter is removed, as since that rust version RawFd implements AsRawFd, allowing it to be used directly in Generic.
• Breaking: The EventSource trait has a new associated type Error. This determines the type of the error variant returned by EventSource::process_events(). It must be convertible into Box<dyn std::error::Error + Sync + Send>.
• Breaking: All library-provided event sources now have their own error types for the associated Error type on the EventSource trait.
• Breaking: Many API functions now use Calloop's own error type (calloop::Error) instead of std::io::Error as the error variants of their returned results.
• Breaking: The Timer event source has been completely reworked and is now directly driven by calloop polling mechanism instead of a background thread. Timer multiplexing is now handled by creating multiple Timers, and self-repeating timers is handled by the return value of the associated event callback.
• Breaking: The minimum supported Rust version is now 1.53.0
• Introduce EventLoop::try_new_high_precision() for sub-millisecond accuracy in the event loop
• The PingSource event source now uses an eventfd instead of a pipe on Linux.

0.9.2 -- 2021-12-27

Additions

• Introduce the methods pre_run() and post_run() to EventSource, allowing event sources to do preparations before entering a run/dispatch session, and cleanup afterwards. They have default implementations doing nothing.

0.9.1 -- 2021-08-10

• Update nix dependency to 0.22

0.9.0 -- 2021-06-29

Breaking changes

• MSRV is now 1.41
• The futures module now has a proper error type for Scheduler::schedule()
• The return type of EventSource::process_events() is now io::Result<PostAction> allowing the sources to directly request the event loop to reregister/disable/destroy them.
• The Token creation mechanism is now driven by a TokenFactory, that dynamically generates new unique token for sub-sources. Following for this if you create a new event source that is not built by composing the ones provided by calloop, you need to check if the Token provided to process_events is the same as the one you created when (re)registering your source. If you delegate process_events to a sub-source, you no longer need to check the sub_id before, instead the source you are delegating to is responsible to to this check.

Bugfixes

• Cancelling a timeout no longer prevents later timeouts from firing.

0.8.0 -- 2021-05-30

Breaking changes

• The Dispatcher type no longer has the closure type within its type parameters, but instead now has an explicit lifetime parameter, as well as the source type S and the event loop Data type. This allows the type to be explicitly named and stored into an other struct.

Additions

• Token now has a method with_sub_id() that returns a copy of the token but with the given sub_id.

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 callbacks 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

0.5.2 -- 2020-04-14

0.5.0 -- 2020-02-07

• Update to 2018 edition
