By knowing if the incoming Request was a HEAD, or checking for 204 or
304 status codes, the server will do a better job of either adding
or removing `Content-Length` and `Transfer-Encoding` headers.
Closes#1257
- Checks for that the `Transfer-Encoding` header has `chunked` as its
last encoding
- Makes `Transfer-Encoding` take priority over `Content-Length`
- Rejects requests that contain a `Content-Length` header, but is
invalid (or contains multiple with different values).
This is a temporary function until the `TryFrom` trait stabilizes.
BREAKING CHANGE: Removes the undocumented `from_u16` function. Use
`StatusCode::try_from` instead.
Also makes the `status` module private. All imports of
`hyper::status::StatusCode` should be `hyper::StatusCode`.
This is actually one of the biggest impacts to benchmark performances at
this point. Caching the rendering of the Date header improves "hello
world" benchmarks by around 10%.
This removes the need for someone to use the `time` crate to create a
date compatible with HTTP headers. It now works with the `SystemTime`
type from the standard library.
BREAKING CHANGE: `HttpDate` no longer has public fields. Convert between
`HttpDate` and `SystemTime` as needed.
BREAKING CHANGE: The `Url` type is no longer used. Any instance in the
`Client` API has had it replaced with `hyper::Uri`.
This also means `Error::Uri` has changed types to
`hyper::error::UriError`.
The type `hyper::header::parsing::HTTP_VALUE` has been made private,
as an implementation detail. The function `http_percent_encoding`
should be used instead.
This commit updates to the most recent versions (released today) of the various
Tokio libraries in use. Namely the `tokio_core::io` module has now been
deprecated in favor of an external `tokio-io` crate. This commit pulls in that
crate and uses the `AsyncRead + AsyncWrite` abstraction instead of `Io` from
tokio-core.
BREAKING CHANGE: Any external types that were using that had implemented `Io` will need to
implement `AsyncRead + AsyncWrite` from tokio_io.
BREAKING CHANGE: The `Preference` header had a typo in a variant and it's string representation,
change `Preference::HandlingLeniant` to `Preference::HandlingLenient`.
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.
