In the scenario where a request is started on the `Client`, the client
has a full slab, and sockets for a *different* domain are idling in
keep-alive, the new request would previously cause the client to panic!.
This patch adds a `spawn_error` handler which attempts to evict an idle
connection to make space for the new request. If space cannot be made,
the error handler is run (passed `Error::Full`) and the `Handler` is
dropped.
This is a breaking change because of the new variant of `Error`.
Some inefficient use of `Vec` in the client was replaced with `VecDeque`
to support push/pop from either end.
Closes#896Closes#897
BREAKING CHANGE: `RequestUri::AbsolutePath` variant is changed to a struct variant. Consider using `req.path()` or `req.query()` to get the relevant slice.
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.
Improve the compile-time of downstream crates that use RequestBuilder,
by not forcing them to remonomorphise and recompile its non-generic
methods when they use it: with this change, they can just call the
precompiled versions in the `hyper` object file(s). The `send` method is
the major culprit here, since it is quite large and complicated.
For an extreme example,
extern crate hyper;
fn main() {
hyper::Client::new().get("x").send().unwrap();
}
takes ~4s to compile before this patch (i.e. generic RequestBuilder) and
~2s after. (The time spent interacting with LLVM goes from 2.2s to
0.3s.)
BREAKING CHANGE: `RequestBuilder<U>` should be replaced by `RequestBuilder`.
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
BREAKING CHANGE: This changes the signature of HttpWriter.end(),
returning a `EndError` that is similar to std::io::IntoInnerError,
allowing HttpMessage to retrieve the broken connections and not panic.
The breaking change isn't exposed in any usage of the `Client` API,
but for anyone using `HttpWriter` directly, since this was technically
a public method, that change is breaking.
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
This will always be the last URL that was used by the Request, which is
useful for determining what the final URL was after redirection.
BREAKING CHANGE: Technically a break, since `Response::new()` takes an
additional argument. In practice, the only place that should have been
creating Responses directly is inside the Client, so it shouldn't
break anyone. If you were creating Responses manually, you'll need to
pass a Url argument.
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: `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
