* timer: restructure feature flags
* update timer tests
* Add `async-traits` to CI
This also disables a buggy `threadpool` test. This test should be fixed in the future.
Refs #1225
## Motivation
The `tokio-trace` and `tokio-trace-core` crates have been renamed to
`tracing` and `tracing-core`, and moved to their own repository
(`tokio-rs/tracing`).
## Solution
This branch removes `tokio-trace` and `tokio-trace-core` from the
`tokio` repository. In addition, I've added a "Related Projects" section
to the root README, which lists `tracing` (as well as `mio`, and
`bytes`) as other libraries maintained by the Tokio project. I thought
that this would help folks looking for `tokio-trace` here find it in its
new home.
In addition, it changes `tokio` to depend on `tracing-core` rather than
`tokio-trace-core`.
Closes#1159

A first pass at updating Tokio to use `std::future`.
Implementations of `Future` from the futures crate are updated to implement
`Future` from std. Implementations of `Stream` are moved to a feature flag.
This commits disables a number of crates that have not yet been updated.
This updates tests to track a fix applied in Mio. Previously, Mio
incorrectly fired HUP events. This was due to Mio mapping `RDHUP` to
HUP. The test is updated to correctly generate a HUP event.
Additionally, HUP events will be removed from all platforms except for
Linux. This is caused by the inability to reliably map kqueue events to
the epoll HUP behavior.
#993 introduces changes in a sub crate that other Tokio crates depend
on. To make CI pass, a `[patch]` statement and `path` dependencies are
used.
When releasing, these must be removed. However, the commit that
removes them and prepares the crates for release will not be able to
pass CI.
This commit adds a conditional on a special `[ci-release]` snippet in
the commit message. If this exists, CI is only run with the full "patched"
dependencies.
Adds a `TypedExecutor` trait that describes how to spawn futures of a specific
type. This is useful for implementing functions that are generic over an executor
and wish to support both `Send` and `!Send` cases.
This patch adds a `blocking` to `tokio-threadpool`. This function serves
as a way to annotate sections of code that will perform blocking
operations. This informs the thread pool that an additional thread needs
to be spawned to replace the current thread, which will no longer be
able to process the work queue.
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.
