BREAKING CHANGE: `Method`, `Request`, `Response`, `StatusCode`,
`Version`, and `Uri` have been replaced with types from the `http`
crate. The `hyper::header` module is gone for now.
Removed `Client::get`, since it needed to construct a `Request<B>`
with an empty body. Just use `Client::request` instead.
Removed `compat` cargo feature, and `compat` related API.
- Deprecates the `no_proto` configuration on `Server`. It is always
enabled.
- Deprecates all pieces related to tokio-proto.
- Makes the tokio-proto crate optional, and the `server-proto` feature
can be used to completely remove the dependency. It is enabled by
default.
- `const_service` creates a `NewService` that clones references to the
wrapped service.
- `service_fn` creates a `Service` from a function. Useful with closures.
For now, this adds `client::Config::no_proto`, `server::Http::no_proto`,
and `server::Server::no_proto` to skip tokio-proto implementations, and
use an internal dispatch system instead.
`Http::no_proto` is similar to `Http::bind_connection`, but returns a
`Connection` that is a `Future` to drive HTTP with the provided service.
Any errors prior to parsing a request, and after delivering a response
(but before flush the response body) will be returned from this future.
See #1342 for more.
The main changes are:
* The entry point is how `Http`, the implementation of `ServerProto`.
This type has a `new` constructor as well as builder methods to
configure it.
* A high-level entry point of `Http::bind` was added which returns a
`Server`. Binding a protocol to a port requires a socket address
(where to bind) as well as the instance of `NewService`. Internally
this creates a core and a TCP listener.
* The returned `Server` has a few methods to learn about itself, e.g.
`local_addr` and `handle`, but mainly has two methods: `run` and
`run_until`.
* The `Server::run` entry point will execute a server infinitely, never
having it exit.
* The `Server::run_until` method is intended as a graceful shutdown
mechanism. When the provided future resolves the server stops
accepting connections immediately and then waits for a fixed period of
time for all active connections to get torn down, after which the
whole server is torn down anyway.
* Finally a `Http::bind_connection` method exists as a low-level entry
point to spawning a server connection. This is used by `Server::run`
as is intended for external use in other event loops if necessary or
otherwise low-level needs.
BREAKING CHANGE: `Server` is no longer the pimary entry point. Instead,
an `Http` type is created and then either `bind` to receiver a `Server`,
or it can be passed to other Tokio things.
There are many changes involved with this, but let's just talk about
user-facing changes.
- Creating a `Client` and `Server` now needs a Tokio `Core` event loop
to attach to.
- `Request` and `Response` both no longer implement the
`std::io::{Read,Write}` traits, but instead represent their bodies as a
`futures::Stream` of items, where each item is a `Chunk`.
- The `Client.request` method now takes a `Request`, instead of being
used as a builder, and returns a `Future` that resolves to `Response`.
- The `Handler` trait for servers is no more, and instead the Tokio
`Service` trait is used. This allows interoperability with generic
middleware.
BREAKING CHANGE: A big sweeping set of breaking changes.
BREAKING CHANGE: Server::https was changed to allow any implementation
of Ssl. Server in general was also changed. HttpConnector no longer
uses SSL; using HttpsConnector instead.
httparse is a http1 stateless push parser. This not only speeds up
parsing right now with sync io, but will also be useful for when we get
async io, since it's push based instead of pull.
BREAKING CHANGE: Several public functions and types in the `http` module
have been removed. They have been replaced with 2 methods that handle
all of the http1 parsing.
All instances of `old_io` and `old_path` were switched to use the new
shiny `std::io`, `std::net`, and `std::path` modules. This means that
`Request` and `Response` implement `Read` and `Write` now.
Because of the changes to `TcpListener`, this also takes the opportunity
to correct the method usage of `Server`. As with other
languages/frameworks, the server is first created with a handler, and
then a host/port is passed to a `listen` method. This reverses what
`Server` used to do.
Closes#347
BREAKING CHANGE: Check the docs. Everything was touched.
This is a modified and specialized thread pool meant for
managing an acceptor in a multi-threaded way. A single handler
is provided which will be invoked on each stream.
Unlike the old thread pool, this returns a join guard which
will block until the acceptor closes, enabling friendly behavior
for the listening guard.
The task pool itself is also faster as it only pays for message passing
if sub-threads panic. In the optimistic case where there are few panics,
this saves using channels for any other communication.
This improves performance by around 15%, all the way to 105k req/sec
on my machine, which usually gets about 90k.
BREAKING_CHANGE: server::Listening::await is removed.
Internals have been shuffled around such that Request and Reponse are
now given only a mutable reference to the stream, instead of being
allowed to consume it. This allows the server to re-use the streams if
keep-alive is true.
A task pool is used, and the number of the threads can currently be
adjusted by using the `listen_threads()` method on Server.
[breaking-change]
A connection is returned from Incoming.next(), and can be passed to a
separate thread before any parsing happens. Call conn.open() to get a
Result<(Request, Response)>.
