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.

- Placed all cases of "unexpected bytes" errors into the
`UnexpectedMessage` variant.
- Placed all cases of "unexpected EOF" errors into the
`IncompleteMessage` variant. Description is now generic about
"connection closed before message completed", instead of mentioning
"request" or "response.
- Added `Error::is_incomplete_message()` accessor to help checking for
unexpected closures.
- Renamed some variants to be clearer when viewing the `Debug` format.
- Collected all "user" errors into an internal `User` enum, to prevent
forgetting to update the `is_user()` method.
The `Error::source()` is searched for an `h2::Error` to allow sending
different error codes in the GOAWAY. If none is found, it defaults to
`INTERNAL_ERROR`.
This option determines whether a read EOF should close the connection
automatically. The behavior was to always allow read EOF while waiting
to respond, so this option has a default of `true`.
Setting this option to `false` will allow Service futures to be canceled
as soon as disconnect is noticed.
Closes#1716
If the Response was received and the body finished while the Request
body was still streaming, the connection could get into a state where it
was never polled again, thus never re-inserting into the connection pool
or being dropped.
Closes#1717
- Adds `Connected::negotiated_h2()` method to signal the connection must
use HTTP2. `Connect` implementations should set this if using ALPN.
If a connection to a host is detected to have been upgraded via ALPN,
any other oustanding connect futures will be canceled, and the waiting
requests will make use of the single HTTP2 connection.
The `http2_only` builder configuration still works the same, not
requiring ALPN at all, and always using only a single connection.
This introduces a `Resolve` trait to describe asynchronous DNS
resolution. The `HttpConnector` can be configured with a resolver,
allowing a user to still use all the functionality of the
`HttpConnector`, while customizing the DNS resolution.
To prevent a breaking change, the `HttpConnector` has its `Resolve`
generic set by default to `GaiResolver`. This is same as the existing
resolver, which uses `getaddrinfo` inside a thread pool.
Closes#1517
- Adds `client::connect::Connected::extra()`, which allows connectors to
specify arbitrary custom information about a connected transport.
If a connector provides this extra value, it will be set in the
`Response` extensions.
Closes#1402
Change behaviour of connection or server response when the request is
version 1.0 and the Connection: keep-alive header is not present.
1. If the response is also version 1.0, then connection is closed if the
server keep-alive header is not present.
2. If the response is version 1.1, then the keep-alive header is added
when downgrading to version 1.0.
Closes#1614
