This removes the cookie crate, since it has an optional dependency on
openssl, which can cause massive breakage if toggled on. Instead, the
`Cookie` and `SetCookie` headers now just use a `String`. Anyone can
create any typed header, so it is easy to plug in different
implementations.
BREAKING CHANGE: The `Cookie` and `SetCookie` headers no longer use the
cookie crate. New headers can be written for any header, or the ones
provided in hyper can be accessed as strings.
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.
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
Make hyper dependant on rust-language-tags providing complete parsing
and formatting of language tags. Remove builtin solution for simple
tags.
BREAKING CHANGE: AcceptLanguage and ContentLanguage use LanguageTag now,
Language removed from Hyper.
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.
The HTML root URL is not supposed to point at the index resource, but
represent the path that can be used to construct the full URL of the
crate's components.
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.
The old names followed the old style of including the module name and
"Error" in each variant. The new style is to refer to an error from its
owning module, and variants are now scoped to their enum, so there's no
need to include the enum name in the variant name.
BREAKING CHANGE: The terms `Http` and `Error` have been removed from the Error
type and its variants. `HttpError` should now be accessed as `hyper::Error`,
and variants like `HttpIoError` should be accessed as `Error::Io`.
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 includes a custom BufReader, since the one in libstd doesn't allow
reading additional data into the buffer without consuming it. This is
required because some connections may send shorter packets, and so we
need to perform multiple reads. After each read, the contents of the
buffer are passed to httparse to see if have a valid message. If so, the
proper amount of bytes are consumed. The additional bytes are left in
the buffer since they are the beginning of the body.
The buffer in this BufReader also grows in size, compared to the libstd
which is sized once. This is because we start with a smaller buffer,
since the majority of messages will be able to include their head in a
packet or 2. Therefore, it's a wasteful performance hit to allocate the
maximum size for every message. However, some headers can be quite big,
and to allow for many of them to be set, we include a maximum size. Once
we've hit the maximum buffer size, and still haven't determined the end
of the headers, a HttpTooLargeError will be returned.
Closes#389
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.
BREAKING CHANGE: added requirement that all HeaderFormat implementations
must also be fmt::Debug. This likely as easy as slapping
#[derive(Debug)] on to any custom headers.
