The only important trait for a user is the `tower::Service` trait, which
is now available also at `hyper::service::Service`. The other "trait
aliases" are no longer publicly exported, as people thought they had to
implement them.
Also removes dependency on `tower-make`, which is trivial but otherwise
shouldn't affect anyone.
Closes#1959
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 `HttpConnector` and `AddrListener` types which make use of
`tokio::tcp` have been made their own optional feature. This allows
using them without requiring the *full* tokio runtime.
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 current `Builder` methods `http2_initial_stream_window_size` and
`http2_initial_connection_window_size` take `&mut self`, while every
other builder method takes `self`. That breaks up the chaining of
options.
This patch adds two methods that configure the same option, but take
`self` instead, and have an underscore suffix (so,
`http2_initial_stream_window_size_`).
cc #1814
- 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`.
* Add `server::conn::Connection::without_shutdown`
Returns wrapper Future instance which allows
to use `poll_without_shutdown` method
more ergonomically.
* Add `client::conn::Connection::without_shutdown`
Returns wrapper Future instance which allows
to use `poll_without_shutdown` method
more ergonomically.
* Improve `poll_without_shutdown` docs
Closes#1786
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
This adjusts the way `Service`s are created for a `hyper::Server`. The
`MakeService` trait allows receiving an argument when creating a
`Service`. The implementation for `hyper::Server` expects to pass a
reference to the accepted transport (so, `&Incoming::Item`). The user
can inspect the transport before making a `Service`.
In practice, this allows for things like getting the remote socket
address, or the TLS certification, or similar.
To prevent a breaking change, there is a blanket implementation of
`MakeService` for any `NewService`. Besides implementing `MakeService`
directly, there is also added `hyper::service::make_service_fn`.
Closes#1650
