BREAKING CHANGE: `hyper::client::request::Response` is no longer generic
over `NetworkStream` types. It no longer requires a generic type
parameter at all.
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 client no longer drops the old `Connector` instance, along with its
entire context (such as the settings and pooled connections in the case
of a `Pool` connector); rather, it passes the SSL verifier on to the
`Connector` so that it uses it for any future connections that it needs
to establish.
A regression test is included.
Closes#495
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.
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`.
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
BREAKING CHANGE: This removes the trait `IntoBody`, and instead using
`Into<Body>`, as it's more idiomatic. This will only have broken code
that had custom implementations of `IntoBody`, and can be fixed by
changing them to `Into<Body>`.
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.
All instances of `old_io` and `old_path` were switched to use the new
shiny `std::io`, `std::net`, and `std::path` modules. This means that
`Request` and `Response` implement `Read` and `Write` now.
Because of the changes to `TcpListener`, this also takes the opportunity
to correct the method usage of `Server`. As with other
languages/frameworks, the server is first created with a handler, and
then a host/port is passed to a `listen` method. This reverses what
`Server` used to do.
Closes#347
BREAKING CHANGE: Check the docs. Everything was touched.
Currently headers are exported at many places. For example you can access
`Transfer-Encoding` header at `header`, `header::common` and
`header::common::transfer_encoding`. Per discussion on IRC with
@seanmonstar and @reem, all contents of headers will be exposed at `header`
directly. Parsing utilities will be exposed at `header::parsing`. Header
macros can now be used from other crates.
This breaks much code using headers. It should use everything it needs
directly from `header::`, encodings are exposed at `header::Encoding::`,
connection options are exposed at `header::ConnectionOption`.
