While the upgrades feature enabled HTTP upgrades in both and the server and client, and the goal was for `CONNECT` requests to work as well, only the server could use them for `CONNECT`. The `Client` had some specific code rejecting `CONNECT` requests, and this removes it and prepares the `Client` to handle them correctly.
If executing an internal task fails, a new variant of `hyper::Error` is
returned to the user, with improved messaging.
If a non-critical task fails to spawn, it no longer panics, instead just
logging a warning.
Closes#1566
- Adds `Body::on_upgrade()` that returns an `OnUpgrade` future.
- Adds `hyper::upgrade` module containing types for dealing with
upgrades.
- Adds `server::conn::Connection::with_upgrades()` method to enable
these upgrades when using lower-level API (because of a missing
`Send` bound on the transport generic).
- Client connections are automatically enabled.
- Optimizes request parsing, to make up for extra work to look for
upgrade requests.
- Returns a smaller `DecodedLength` type instead of the fatter
`Decoder`, which should also allow a couple fewer branches.
- Removes the `Decode::Ignore` wrapper enum, and instead ignoring
1xx responses is handled directly in the response parsing code.
Ref #1563Closes#1395
- The `cause2` method adds a `'static` bound, allowing to downcast the error type.
- The `into_cause` method converts an `Error` into its optional cause.
Closes#1542
This allows a client or server to indicate that the body should be cut off
in an abnormal fashion so the server doesn't simply get a "valid" but
truncated body.
If an HTTP/1 connection has a parse error, but it starts with the HTTP2 preface, converts the connection automatically into an HTTP2 server connection.
Closes#1486
A Cargo feature `runtime` is added, which is enabled by default, that
includes the following:
- The `client::HttpConnector`, which uses `tokio::net::TcpStream`.
- The `server::AddrStream`, which uses `tokio::net::TcpListener`.
- The `hyper::rt` module, which includes useful utilities to work with
the runtime without needing to import `futures` or `tokio` explicity.
Disabling the feature removes many of these niceties, but allows people
to use hyper in environments that have an alternative runtime, without
needing to download an unused one.
This introduces the `hyper::service` module, which replaces
`tokio-service`.
Since the trait is specific to hyper, its associated
types have been adjusted. It didn't make sense to need to define
`Service<Request=http::Request>`, since we already know the context is
HTTP. Instead, the request and response bodies are associated types now,
and slightly stricter bounds have been placed on `Error`.
The helpers `service_fn` and `service_fn_ok` should be sufficient for
now to ease creating `Service`s.
The `NewService` trait now allows service creation to also be
asynchronous.
These traits are similar to `tower` in nature, and possibly will be
replaced completely by it in the future. For now, hyper defining its own
allows the traits to have better context, and prevents breaking changes
in `tower` from affecting hyper.
Closes#1461
BREAKING CHANGE: The `Service` trait has changed: it has some changed
associated types, and `call` is now bound to `&mut self`.
The `NewService` trait has changed: it has some changed associated
types, and `new_service` now returns a `Future`.
`Client` no longer implements `Service` for now.
`hyper::server::conn::Serve` now returns `Connecting` instead of
`Connection`s, since `new_service` can now return a `Future`. The
`Connecting` is a future wrapping the new service future, returning
a `Connection` afterwards. In many cases, `Future::flatten` can be
used.
The `hyper::Server` is now a proper higher-level API for running HTTP
servers. There is a related `hyper::server::Builder` type, to construct
a `Server`. All other types (`Http`, `Serve`, etc) were moved into the
"lower-level" `hyper::server::conn` module.
The `Server` is a `Future` representing a listening HTTP server. Options
needed to build one are set on the `Builder`.
As `Server` is just a `Future`, it no longer owns a thread-blocking
executor, and can thus be run next to other servers, clients, or
what-have-you.
Closes#1322Closes#1263
BREAKING CHANGE: The `Server` is no longer created from `Http::bind`,
nor is it `run`. It is a `Future` that must be polled by an
`Executor`.
The `hyper::server::Http` type has move to
`hyper::server::conn::Http`.
**The `Error` is now an opaque struct**, which allows for more variants to
be added freely, and the internal representation to change without being
breaking changes.
For inspecting an `Error`, there are several `is_*` methods to check for
certain classes of errors, such as `Error::is_parse()`. The `cause` can
also be inspected, like before. This likely seems like a downgrade, but
more inspection can be added as needed!
The `Error` now knows about more states, which gives much more context
around when a certain error occurs. This is also expressed in the
description and `fmt` messages.
**Most places where a user would provide an error to hyper can now pass
any error type** (`E: Into<Box<std::error::Error>>`). This error is passed
back in relevant places, and can be useful for logging. This should make
it much clearer about what error a user should provide to hyper: any it
feels is relevant!
Closes#1128Closes#1130Closes#1431Closes#1338
BREAKING CHANGE: `Error` is no longer an enum to pattern match over, or
to construct. Code will need to be updated accordingly.
For body streams or `Service`s, inference might be unable to determine
what error type you mean to return. Starting in Rust 1.26, you could
just label that as `!` if you never return an error.
BREAKING CHANGE: `Method`, `Request`, `Response`, `StatusCode`,
`Version`, and `Uri` have been replaced with types from the `http`
crate. The `hyper::header` module is gone for now.
Removed `Client::get`, since it needed to construct a `Request<B>`
with an empty body. Just use `Client::request` instead.
Removed `compat` cargo feature, and `compat` related API.
Currently, if the remote closes the connection at the same time that the
pool selects it to use for a new request, the connection may actually
hang. This fix will now more allow the keep-alive read to check the
socket even when the `Conn` think it's busy.
If the connection was closed before the request write happened, returns
back an `Error::Cancel`, letting the user know they could safely retry
it.
Closes#1439
BREAKING CHANGE: The `Url` type is no longer used. Any instance in the
`Client` API has had it replaced with `hyper::Uri`.
This also means `Error::Uri` has changed types to
`hyper::error::UriError`.
The type `hyper::header::parsing::HTTP_VALUE` has been made private,
as an implementation detail. The function `http_percent_encoding`
should be used instead.
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.
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.
Access-Control-Allow-Origin origins are URLs but they do not need to
be valid, they should just be compared as strings. So to support
invalid URLs hyper should use a string instead.
closes#526
BREAKING CHANGE: Access-Control-Allow-Origin does no longer use Url
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.
Header::parse_header() returns now a hyper Result instead of an option
this will enable more precise Error messages in the future, currently
most failures are reported as ::Error::Header.
BREAKING CHANGE: parse_header returns Result instead of Option, related
code did also change
Automatic conversion from the `solicit::http::HttpError` is also
provided.
BREAKING CHANGE: A new variant `Http2` added to a public enum
`hyper::Error`.
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`.
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.
