Prior to this commit, connections from 'sync_db_pools' assumed that they
were being dropped in an async context. This is overwhelmingly the
common case as connections are typically dropped immediately after
request processing. Nothing requires this, however, so holding a
connection beyond the scope of the async context was possible (i.e. by
storing a connection in managed state). Given the connection's `Drop`
impl calls `spawn_blocking`, this resulted in a panic on drop.
This commit resolves the issue by modifying `Drop` so that it calls
`spawn_blocking` only when it is executing inside an async context. If
not, the connection is dropped normally, without `spawn_blocking`.
Also modifies the `databases` example so that it makes use of the new
ability to run migrations in diesel-async v0.5. To accomplish this,
`diesel_async::async_connection_wrapper::AsyncConnectionWrapper` is
exported from `rocket_db_pools::diesel` and used in the `diesel_mysql`
portion of the `databases` example. The URL for the MySQL version of the
database example is now `/mysql` instead of `/diesel-async`.
This commit complete the migration to 'tracing' for all logging. Below
is a summary of all relevant commits, including this one:
Log improvements:
- All log (trace) messages are structured which means they contain fields
that can formatted by any subscriber.
- Logging can be disabled entirely by disabling the default `trace` feature.
- Routes and catchers now contain location (file/line) information.
- Two log format kinds: pretty and compact via ROCKET_LOG_FORMAT
- Coloring is not disabled globally. Thus applications can color even if
Rocket is configured not to.
- Rocket is more conservative about 'warn' and 'error' messages, reserving
those log levels for messages useful in production.
- Errors from guards logged by codegen now use the 'Display' implementation of
those errors when one exists.
- Secrets are never logged, even when directly asked for.
New features:
- Many Rocket types know how to trace themselves via a new `Trace` trait.
- `Either` types can now be used in `uri!()` calls.
- A `RequestIdLayer` tags all requests with a unique ID.
Breaking changes to configuration:
- `Config::log_level` is of type `Option<Level>`. `None` disables tracing.
- `log_level` now uses the traditional log level names: "off", "error",
"warn", "info", "debug", "trace", or 0-5. This replace the Rocket-specific
"normal", "debug", "critical".
- A new option, `log_format`, which is either `compact` or `pretty`,
determines how Rocket's tracing subscriber log trace messages.
Breaking changes:
- Hidden `rocket::Either` is now publicly available at `rocket::either::Either`.
- `rocket::Error` no longer panics when dropped.
- `main` generated by `#[launch]` returns an `ExitCode`.
- `FromParam` `Err` now always returns the actual error as opposed to the
string that failed to parse. To recover the original string, use `Either<T,
&str>`, where `T: FromParam`, as a parameter guard.
- Many types that implemented `Display` now instead implement `Trace`.
- `Error::pretty_print()` was removed. Use `Error::trace()` via `Trace` impl.
Internal improvements:
- Made more space in CI machines for tasks.
- Cleaned up testbench code using `inventory`.
Resolves#21.
This commit:
- Removes painting outside trace subscriber in core.
- Removes all non-subscriber uses of yansi.
- Removes all uses of old log macros.
- Fix trace exports.
This commit introduces the ability to dynamically select a TLS
configuration based on the client's TLS hello via the new `Resolver`
trait. In support of this, it also makes the following changes:
* Added `Authority::set_port()`.
* `UdsListener` is now `UnixListener`.
* `Bindable` removed in favor of new `Bind`.
* All built-in listeners now implement `Bind<&Rocket>`.
* `Connection` requires `AsyncRead + AsyncWrite`.
* The `Debug` impl for `Endpoint` displays the underlying address.
* `Listener` must be `Sized`.
* The TLS listener was moved to `tls::TlsListener`.
* The preview `quic` listener no longer implements `Listener`.
* Added `TlsConfig::server_config()`.
* Added `race` future helpers.
* Added `Rocket::launch_with()`, `Rocket::bind_launch()`.
* Added a default `client.pem` to the TLS example.
* Various unnecessary listener `Config` structures removed.
In addition, the testbench was revamped to support more scenarios. This
resulted in the following issues being found and fixed:
* Fix an issue where the logger would ignore color requests.
* Clarified docs for `mtls::Certificate` guard.
* Improved error messages on listener misconfiguration.

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.
This commit makes passing compile UI tests optional, allowing the CI to
succeed even when UI tests fail. This change was made because UI tests
are highly susceptible to false negatives due to benign rustc compiler
output changes. A failure resulting from such a benign change inhibits
progress in the main branch due to failing PR testing which would have
otherwise passed.
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.
