Extract `tokio::executor::current_thread` to a tokio-current-thread
crate. Deprecated fns stay in the old location. The new crate only
contains thee most recent API.
This patch adds a new crate: tokio-fs. This crate provides a wrapper
around `std` functionality that can only be performed using blocking
operations. This primarily includes filesystem operations, but it also
includes standard input, output, and error access as these streams
cannot be safely switched to non-blocking mode in a portable way.
These wrappers call the `std` functions from within a `blocking`
annotation which allows the runtime to compensate for the fact that the
thread will potentially remain blocked in a system call.
Currently, the state of the futures2 integration is pretty broken. This
patch removes the feature flag, preventing users from trying to use it.
In the future, it can be brought back when the implementation is fixed.
This patch integrate the new timer implementation with the runtime by
initializing a timer per worker thread. This allows minimizing the
amount of synchronization needed for using timers.
This patch adds a new crate: tokio-timer. This crate provides an
efficient timer implemeentation designed for use in Tokio based
applications.
The timer users a hierarchical hashed timer wheel algorithm with six
levels, each having 64 slots. This allows the timer to have a resolution
of 1ms while maintaining O(1) complexity for insert, removal, and firing
of timeouts.
There already exists a tokio-timer crate. This is a complete rewrite
which solves the outstanding problems with the existing tokio-timer
library.
Closes#146.
This patch relicenses the Tokio project exclusively under the MIT
license. Before this, the project was dual licensed under MIT and Apache
2. As such, switching to only MIT is permitted.
Fixes#202
This patch updates `poll_read_ready` to take a `mask` argument, enabling
the caller to specify the desired readiness. `need_read` is renamed to
`clear_read_ready` and also takes a mask.
This enables a caller to listen for HUP events without requiring reading
from the I/O resource.
This allows libraries that require access to reactor related types to
depend on this crate without having to depend on the entirety of Tokio.
For example, libraries that implement their custom I/O resource will
need to access `Registration` or `PollEvented`.
This patch updates the documentation for a number of APIs. It also
introduces a prelude module and an io facade module, re-exporting types
from tokio-io.
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.
This should allow configuration over what reactor accepted streams go on to by
giving back a libstd-bound object that can then be used later in conjunction
with `TcpStream::from_std`.
* Make Handle `Send + Sync`.
This is an initial implementation making `Handle: Send + Sync`. It uses
a `RwLock` to coordinate access to the underlying state storage. An
implementation without the lock is left to later.
This pass also leaves a lot of dead code that can be removed in later
commits.
* Remove reactor code related to message passing
The previous commit removed the need for using message passing to
communicate with the reactor. This commit removes all the unnecessary
code.
