If a request sees an error on a pooled connection before ever writing
any bytes, it will now retry with a new connection.
This can be configured with `Config::retry_canceled_requests(bool)`.
On some OSes, `Instant` would start counting 0 from the boot time. That
would mean that any `Instant::now() - dur` soon after boot had a higher
risk of overflowing. Now, the expiration is determined by calling
`idle.elapsed()`, and comparing durations.
Closes#1215
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.
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.
Methods added to `Client` and `Server` to control read and write
timeouts of the underlying socket.
Keep-Alive is re-enabled by default on the server, with a default
timeout of 5 seconds.
BREAKING CHANGE: This adds 2 required methods to the `NetworkStream`
trait, `set_read_timeout` and `set_write_timeout`. Any local
implementations will need to add them.
When an Http11Message knows that the previous response should not
have included a body per RFC7230, and fails to parse the following
response, the bytes are shuffled along, checking for the start of the
next response.
Closes#640
While these methods are marked unstable in libstd, this is behind a
feature flag, `timeouts`. The Client and Server both have
`set_read_timeout` and `set_write_timeout` methods, that will affect all
connections with that entity.
BREAKING CHANGE: Any custom implementation of NetworkStream must now
implement `set_read_timeout` and `set_write_timeout`, so those will
break. Most users who only use the provided streams should work with
no changes needed.
Closes#315
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.
BREAKING CHANGE: Any custom Connectors will need to change to &self in
the connect method. Any Connectors that needed the mutablity need to
figure out a synchronization strategy.
Request::with_connector() takes a &NetworkConnector instead of &mut.
Any uses of with_connector will need to change to passing &C.
The commit includes an implementation of the new trait method for all
existing trait impls.
BREAKING CHANGE: Adding a new required method to a public trait is a
breaking change.
The errors from openssl were previously boxed into a
Box<std::error::Error>, which lost some specifics and made it difficult
to match against. To solve this, an `Ssl` variant is added to the
`Error` enum of hyper, and is returned when openssl returns specific
errors.
Closes#483
BREAKING CHANGE: Adds a variant to `hyper::Error`, which may break any
exhaustive matches.
This adds a connection pool to the Client that is used by default. It
accepts any other NetworkConnector, and simply acts as a
NetworkConnector itself. Other Pools can exist by simply providing a
custom NetworkConnector. This Pool is only used by default if you also
use the default connector, which is `HttpConnector`. If you wish to use
the Pool with a custom connector, you'll need to create the Pool with
your custom connector, and then pass that pool to the
Client::with_connector.
This also adds a method to `NetworkStream`, `close`, which can be used
to know when the Stream should be put down, because a server requested
that the connection close instead of be kept alive.
