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.
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.
Generates a new method on attributed types, `pool()`, which returns an
opaque reference to a type that can be used to get pooled connections.
Also adds a code-generated example to the crate docs which includes
real, proper function signatures and fully checked examples.
Resolves#1884.
Closes#1972.
This follows the completed graduation of stable contrib features into
core, removing 'rocket_contrib' in its entirety in favor of two new
crates. These crates are versioned independently of Rocket's core
libraries, allowing upgrades to dependencies without consideration for
versions in core libraries.
'rocket_dyn_templates' replaces the contrib 'templates' features. While
largely a 1-to-1 copy, it makes the following changes:
* the 'tera_templates' feature is now 'tera'
* the 'handlebars_templates' feature is now 'handlebars'
* fails to compile if neither 'tera' nor 'handlebars' is enabled
'rocket_sync_db_pools' replaces the contrib 'database' features. It
makes no changes to the replaced features except that the `database`
attribute is properly documented at the crate root.
