* Fix races.
This mostly pulls in changes from rust-lang-nursery/futures-rs#881, but
also updates Registration to be a bit more obvious as to what is going
on.
* Reduce spurious wakeups caused by Reactor
This patch adds an ABA guard on token values before registering them
with Mio. This allows catching token reuse and avoid the notification.
This is needed for OS X as the notification is used to determine that a
TCP connect has completed. A spurious notification can potentially cause
write failures.
Currently, if a thread pool instance is dropped without being shutdown,
the workers will run indefinitely. This is not ideal as it leaks the
threadpool.
This patch forces the thread pool to shutdown on drop.
Closes#151
This patch is an intial implementation of the Tokio runtime. The Tokio
runtime provides an out of the box configuration for running I/O heavy
asynchronous applications.
As of now, the Tokio runtime is a combination of a work-stealing thread
pool as well as a background reactor to drive I/O resources.
This patch also includes tokio-executor, a hopefully short lived crate
that is based on the futures 0.2 executor RFC.
* Implement `Park` for `Reactor`
This enables the reactor to be used as the thread parker for executors.
This also adds an `Error` component to `Park`. With this change, a
`Reactor` and a `CurrentThread` can be combined to achieve the
capabilities of tokio-core.
