- Placed all cases of "unexpected bytes" errors into the
`UnexpectedMessage` variant.
- Placed all cases of "unexpected EOF" errors into the
`IncompleteMessage` variant. Description is now generic about
"connection closed before message completed", instead of mentioning
"request" or "response.
- Added `Error::is_incomplete_message()` accessor to help checking for
unexpected closures.
- Renamed some variants to be clearer when viewing the `Debug` format.
- Collected all "user" errors into an internal `User` enum, to prevent
forgetting to update the `is_user()` method.
The `Error::source()` is searched for an `h2::Error` to allow sending
different error codes in the GOAWAY. If none is found, it defaults to
`INTERNAL_ERROR`.
This option determines whether a read EOF should close the connection
automatically. The behavior was to always allow read EOF while waiting
to respond, so this option has a default of `true`.
Setting this option to `false` will allow Service futures to be canceled
as soon as disconnect is noticed.
Closes#1716
If the Response was received and the body finished while the Request
body was still streaming, the connection could get into a state where it
was never polled again, thus never re-inserting into the connection pool
or being dropped.
Closes#1717
- Adds `Connected::negotiated_h2()` method to signal the connection must
use HTTP2. `Connect` implementations should set this if using ALPN.
If a connection to a host is detected to have been upgraded via ALPN,
any other oustanding connect futures will be canceled, and the waiting
requests will make use of the single HTTP2 connection.
The `http2_only` builder configuration still works the same, not
requiring ALPN at all, and always using only a single connection.
This introduces a `Resolve` trait to describe asynchronous DNS
resolution. The `HttpConnector` can be configured with a resolver,
allowing a user to still use all the functionality of the
`HttpConnector`, while customizing the DNS resolution.
To prevent a breaking change, the `HttpConnector` has its `Resolve`
generic set by default to `GaiResolver`. This is same as the existing
resolver, which uses `getaddrinfo` inside a thread pool.
Closes#1517
- Adds `client::connect::Connected::extra()`, which allows connectors to
specify arbitrary custom information about a connected transport.
If a connector provides this extra value, it will be set in the
`Response` extensions.
Closes#1402
Change behaviour of connection or server response when the request is
version 1.0 and the Connection: keep-alive header is not present.
1. If the response is also version 1.0, then connection is closed if the
server keep-alive header is not present.
2. If the response is version 1.1, then the keep-alive header is added
when downgrading to version 1.0.
Closes#1614
If a user makes use of `Body::is_end_stream` to optimize so as to not
need to do make a final poll just to receive `None`, previously the
connection would not have progressed its reading state to a finished
body, and so the connection would be closed.
Now, upon reading any chunk, the connection state will check if it
can know that the body would be finished, and progresses to a body
finished state sooner.
The integration tests were amplified by adding a naive hyper proxy
as a secondary test, which happens to make use of that optimization,
and thus caught the issue.
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.
- Add `Body::Kind::H2` to contain the content length of the body.
- Update `Body::content_length` to return the content length if `Body::Kind` is `H2`, instead of returning `None`.
Reference: #1556, #1557Closes#1546
- 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
Automatically removes "connection" headers before sending over HTTP2.
These headers are illegal in HTTP2, and would otherwise cause errors.
Closes: #1551
When getting a `Body` from hyper, such as in a client response,
the method `Body::content_length()` now returns a value if the header
was present.
Closes#1545
- In the higher-level `Server` API, since connection upgrades aren't yet
supported, returning a 2xx response to a `CONNECT` request is a user
error. A 500 response is written to the client, the connection is
closed, and an error is reported back to the user.
- In the lower-level `server::Connection` API, where upgrades *are*
supported, a 2xx response correctly marks the response as the final
one, instead of trying to parse more requests afterwards.
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.
- When the `Body` is created from a buffer of bytes (such as
`Body::from("hello")`), we can skip some bookkeeping that is
normally required for streaming bodies.
- Orthogonally, optimize encoding body chunks when the strategy
is to flatten into the headers buf, by skipping the EncodedBuf
enum.
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
