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.
This should fix some busy looping when using OpenSSL. For example, if
the transport was blocked on a read, it wasn't surfaced to the
`http::Conn` and so the wrong interest was registered with the event
loop. Registering for the wrong interest triggered calls to
`http::Conn::ready()` which were unable to make progress.
SSL libraries other than OpenSSL don't necessarily have the ability to
easily create server and client side connections at the same time. This
is backwards compatible due to blanket impls.
Closes#756
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
This allows HttpStream and HttpListener to be created from raw
sockets similar to their Tcp counterparts. It also fixes up the
signature from i32 to RawFd for the AsRawFd method.
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.
Connector::connect already used &self, and so would require
synchronization to be handled per connector anyway. Adding Sync to the
Client allows users to setup config for a Client once, such as using a
single connection Pool, and then making requests across multiple
threads.
Closes#254
BREAKING CHANGE: Connectors and Protocols passed to the `Client` must
now also have a `Sync` bounds, but this shouldn't break default usage.
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.
On OSX, calling shutdown a second time will return a NotConnected error.
This commit will just ignore it, since we can agree that if a stream is
"not connected", it is in fact "closed".
Closes#508
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.
Closes#363Closes#41
Closes#379
BREAKING CHANGE: For people using the default HttpConnector and Client,
everything should continue to just work. If the Client has been
used with a generic parameter, it should be removed.
However, there were some breaking changes to the internals of
NetworkConnectors. Specifically, they no longer return a
NetworkStream, but instead a Into<Box<NetworkStream + Send>>. All
implementations of NetworkStream should continue to just work,
however.
Possible breakages could come from the stricter usage of Send
throughout the Client API.
This commit fixes `cargo build` and `cargo test`.
Method lookup on traits seems to have changed to force
`impl TraitName` expressions to be more specific. That means that
`method` will not be found anymore on an object of type `&Trait+Send`,
unless you provide an `impl Trait+Send`.
Now `NetworkStream` and `HeaderFormat` trait implementations
are done against `* + Send`, which helps the compiler to find the
respective `downcast*` method implementations once again.
httparse is a http1 stateless push parser. This not only speeds up
parsing right now with sync io, but will also be useful for when we get
async io, since it's push based instead of pull.
BREAKING CHANGE: Several public functions and types in the `http` module
have been removed. They have been replaced with 2 methods that handle
all of the http1 parsing.
