This commit is a codebase-wide cleanup driven by clippy warnings. In
addition to fixing every reasonable warning, the following new
functionality was introduced:
* `Accept::new()` now takes any `T: Into<QMediaType>` iterator.
* `TempFile::is_empty()` was added.
* `HeaderMap` now implements `IntoIterator`.
This commit makes the following breaking changes:
* The `IntoCollection` trait is gone. Generics previously bound by the
trait are now bound by `IntoIterator`. This affects:
- `Accept::new()`
- `ContentType::with_params()`
- `Permission::{allow, allowed}()`
* `MediaType`, `QMediaType`, and `Allow` implement `IntoIterator`,
enabling most existing code to continue working without change.
* The inherent `HeaderMap::into_iter()` method was removed.
* The `Ok` variant in ErrorKind::Liftoff` is now `Box<Rocket<Orbit>>`.
This commit adds support for HTTP/3 and QUIC under a disabled-by-default
feature `http3-preview`. The current implementation depends on modified
versions of h3 and s2n-quic-h3 which will need to be upstreamed and
published before a release is possible.
During the course of development various facets of Rocket's internal
connection handling and recent listener APIs were improved. The complete
list of changes included in this PR is:
* A `shutdown` module was introduced.
* `config::Shutdown` was renamed to `ShutdownConfig` and moved to
`shutdown` while being re-exported from `config`.
* `ListenerAddr` is now called `Endpoint`. Various methods which
previously referred to "addresses" now refer to "endpoints".
* `Rocket::endpoint()` was renamed to `Rocket::endpoints()` and now
returns an iterator over the endpoints Rocket is listening on.
* `Endpoint` acquired various query utility methods.
* The `{set_}remote()` methods now take/produce `Endpoint`s.
* `TlsBindable` only accepts single-phase internal interfaces.
* Bind error messages include candidate endpoint info when possible.
* The warning message when a secret key is not configured now includes
information about its effect on private cookies.
Internal changes include:
* Config module tests were moved to `config/tests.rs`.
* The cancellable I/O implementation was significantly simplified.
* The `TripWire` implementation was simplified.
* Individual shutdown stages can now be awaited on via `Stages`.
* The `Shield` implementation was simplified.
Resolves#2723.
This commit completely rewrites Rocket's HTTP serving. In addition to
significant internal cleanup, this commit introduces the following major
features:
* Support for custom, external listeners in the `listener` module.
The new `listener` module contains new `Bindable`, `Listener`, and
`Connection` traits which enable composable, external
implementations of connection listeners. Rocket can launch on any
`Listener`, or anything that can be used to create a listener
(`Bindable`), via a new `launch_on()` method.
* Support for Unix domain socket listeners out of the box.
The default listener backwards compatibly supports listening on Unix
domain sockets. To do so, configure an `address` of
`unix:path/to/socket` and optional set `reuse` to `true` (the
default) or `false` which controls whether Rocket will handle
creating and deleting the unix domain socket.
In addition to these new features, this commit makes the following major
improvements:
* Rocket now depends on hyper 1.
* Rocket no longer depends on hyper to handle connections. This allows
us to handle more connection failure conditions which results in an
overall more robust server with fewer dependencies.
* Logic to work around hyper's inability to reference incoming request
data in the response results in a 15% performance improvement.
* `Client`s can be marked secure with `Client::{un}tracked_secure()`,
allowing Rocket to treat local connections as running under TLS.
* The `macros` feature of `tokio` is no longer used by Rocket itself.
Dependencies can take advantage of this reduction in compile-time
cost by disabling the new default feature `tokio-macros`.
* A new `TlsConfig::validate()` method allows checking a TLS config.
* New `TlsConfig::{certs,key}_reader()`,
`MtlsConfig::ca_certs_reader()` methods return `BufReader`s, which
allow reading the configured certs and key directly.
* A new `NamedFile::open_with()` constructor allows specifying
`OpenOptions`.
These improvements resulted in the following breaking changes:
* The MSRV is now 1.74.
* `hyper` is no longer exported from `rocket::http`.
* `IoHandler::io` takes `Box<Self>` instead of `Pin<Box<Self>>`.
- Use `Box::into_pin(self)` to recover the previous type.
* `Response::upgrade()` now returns an `&mut dyn IoHandler`, not
`Pin<& mut _>`.
* `Config::{address,port,tls,mtls}` methods have been removed.
- Use methods on `Rocket::endpoint()` instead.
* `TlsConfig` was moved to `tls::TlsConfig`.
* `MutualTls` was renamed and moved to `mtls::MtlsConfig`.
* `ErrorKind::TlsBind` was removed.
* The second field of `ErrorKind::Shutdown` was removed.
* `{Local}Request::{set_}remote()` methods take/return an `Endpoint`.
* `Client::new()` was removed; it was previously deprecated.
Internally, the following major changes were made:
* A new `async_bound` attribute macro was introduced to allow setting
bounds on futures returned by `async fn`s in traits while
maintaining good docs.
* All utility functionality was moved to a new `util` module.

Resolves#1070.
Tokio's `File::write_all()` method has an unexpected quirk: it doesn't
actually write all the requested content to the file when the returned
future resolves. Instead, the write is attempted and queued. This means
that the `persist()` method can resolve without the data being persisted
to the file system. Subsequent reads of the ostensibly written-to file
can thus fail to contain the expected data.
An call to `flush()` following `write_all()` would circumvent the issue.
Alternatively, calling `fs::write()` actually writes to the file system
before returning and requires fewer lines of code. This commit thus
swaps the call to `write_all()` with `fs::write()`.
In the process, the following improvements were also made:
* Error messages related to TLS were improved.
* 'Redirector' in 'tls' example was improved.
Previously, the `NotFound` status code was used to signal many kinds of
recoverable, forwarding errors. This included validation errors, incorrect
Content-Type errors, and more.
This commit modifies the status code used to forward in these instances to more
precisely indicate the forwarding condition. In particular:
* Parameter `FromParam` errors now forward as 422 (`UnprocessableEntity`).
* Query paramater errors now forward as 422 (`UnprocessableEntity`).
* Use of incorrect form content-type forwards as 413 (`UnsupportedMediaType`).
* `WebSocket` guard now forwards as 400 (`BadRequest`).
* `&Host`, `&Accept`, `&ContentType`, `IpAddr`, and `SocketAddr` all forward
with a 500 (`InternalServerError`).
Additionally, the `IntoOutcome` trait was overhauled to support functionality
previously offered by methods on `Outcome`. The `Outcome::forward()` method now
requires a status code to use for the forwarding outcome.
Finally, logging of `Outcome`s now includes the relevant status code.
Resolves#2626.
The primary motivation is to deconflate the leading `F`s in `Failure` and
`Forward`. In particular, when using a generics, we used `F` for forward, which
could easily be confused for `F` for `Failure`. This resolves the conflation.
Previously, `async_main` would extract a full `Config`. This mean that values
like `address` were read and parsed even when they were unused. Should they
exist and be malformed, a configuration error would needlessly arise.
This commit fixes this by only extract values that are subsequently used.
The compatibility normalizer previously missed or was overly egregious
in several cases. This commit resolves those issue. In particular:
* Only request URIs that would not match any route are normalized.
* Synthetic routes are added to the igniting `Rocket` so that requests
with URIs of the form `/foo` match routes with URIs of the form
`/foo/<b..>`, as they did prior to the trailing slash overhaul.
Tests are added for all of these cases.
Prior to this commit, a route with a URI of `/` could not be mounted in
such a way that the resulting effective URI contained a trailing slash.
This commit changes the semantics of mounting so that mounting such a
route to a mount point with a trailing slash yields an effective URI
with a trailing slash. When mounted to points without a trailing slash,
the effective URI does not have a trailing slash.
This commit also introduces the `Route::rebase()` and
`Catcher::rebase()` methods for easier rebasing of existing routes and
catchers.
Finally, this commit improves logging such that mount points of `/`
are underlined in the logs.
Tests and docs were added and modified as necessary.
Resolves#2533.
Prior to this commit, all forward outcomes resulted in a 404. This
commit changes request and data guards so that they are able to provide
a `Status` on `Forward` outcomes. The router uses this status, if the
final outcome is to forward, to identify the catcher to invoke.
The net effect is that guards can now customize the status code of a
forward and thus the error catcher invoked if the final outcome of a
request is to forward.
Resolves#1560.
This commit exposes four new methods:
* `Route::collides_with(&Route)`
* `Route::matches(&Request)`
* `Catcher::collides_with(&Catcher)`
* `Catcher::matches(Status, &Request)`
Each method checks the corresponding condition: whether two routes
collide, whether a route matches a request, whether two catchers
collide, and whether a catcher matches an error arising from a request.
This functionality is used internally by Rocket to make routing
decisions. By exposing these methods, external libraries can use
guaranteed consistent logic to check the same routing conditions.
Resolves#1561.
