Previously, hyper returned an "Invalid chunk end CR" error on chunked
responses with trailers, as described in RFC 7230 Section 4.1.2. This
commit adds code to ignore the trailers.
Closes#2171
cc #2251
BREAKING CHANGE: This puts all HTTP/1 methods and support behind an
`http1` cargo feature, which will not be enabled by default. To use
HTTP/1, add `features = ["http1"]` to the hyper dependency in your
`Cargo.toml`.
This adds HTTP2 keep-alive support to client and server connections
based losely on GRPC keep-alive. When enabled, after no data has been
received for some configured interval, an HTTP2 PING frame is sent. If
the PING is not acknowledged with a configured timeout, the connection
is closed.
Clients have an additional option to enable keep-alive while the
connection is otherwise idle. When disabled, keep-alive PINGs are only
used while there are open request/response streams. If enabled, PINGs
are sent even when there are no active streams.
For now, since these features use `tokio::time::Delay`, the `runtime`
cargo feature is required to use them.
- Renamed `keep_alive_timeout` to `pool_idle_timeout`.
- Renamed `max_idle_per_host` to `pool_max_idle_per_host`.
- Deprecated `keep_alive(bool)` due to confusing name. To disable the
connection pool, call `pool_max_idle_per_host(0)`.
Before, if a client request included an `Expect: 100-continue` header,
the `100 Continue` response was sent immediately. However, this is
problematic if the service is going to reply with some 4xx status code
and reject the body.
This change delays the automatic sending of the `100 Continue` status
until the service has call `poll_data` on the request body once.
When the body type of a `Request` or `Response` implements `HttpBody`,
the `Request` or `Response` itself now implements `HttpBody`.
This allows writing things like `hyper::body::aggregate(req)` instead of
`hyper::body::aggregate(req.into_body())`.
Closes#2067
Adds utility functions to `hyper::body` to help asynchronously
collecting all the buffers of some `HttpBody` into one.
- `aggregate` will collect all into an `impl Buf` without copying the
contents. This is ideal if you don't need a contiguous buffer.
- `to_bytes` will copy all the data into a single contiguous `Bytes`
buffer.
Instead of returning a tuple `(impl AsyncRead + AsyncWrite, Connected)`,
this adds a new trait, `hyper::client::connect::Connection`, which
allows querying the connection type for a `Connected`.
BREAKING CHANGE: Connectors no longer return a tuple of
`(T, Connected)`, but a single `T: Connection`.
Closes#1903
BREAKING CHANGE: The `Resolve` trait is gone. All custom resolves should
implement `tower::Service` instead.
The error type of `HttpConnector` has been changed away from
`std::io::Error`.
The `Connect` trait is now essentially an alias for
`Service<Destination>`, with a blanket implementation as such, and is
sealed.
Closes#1902
BREAKING CHANGE: Any manual implementations of `Connect` must instead
implement `tower::Service<Destination>`.
Detecting a read hangup is a useful way to determine that a connection
has closed. It's also possible that a client shuts down its read half
without closing the connection, but this is rarer. Thus, by default,
hyper will now assume a read EOF means the connection has closed.
BREAKING CHANGE: The server's behavior will now by default close
connections when receiving a read EOF. To allow for clients to close
the read half, call `http1_half_close(true)` when configuring a
server.
The `Accept` trait is used by the server types to asynchronously accept
incoming connections. This replaces the previous usage of `Stream`.
BREAKING CHANGE: Passing a `Stream` to `Server::builder` or
`Http::serve_incoming` must be changed to pass an `Accept` instead. The
`stream` optional feature can be enabled, and the a stream can be
converted using `hyper::server:🉑:from_stream`.
The previous version is renamed to `try_send_data`.
BREAKING CHANGE: Usage of `send_data` should either be changed to
async/await or use `try_send_data`.
These tests were temporarily disabled during the migration to the
`std::future::Future` type that's part of the stable Rust now.
This commit updates the tests after the breaking changes and makes them
pass again.
