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.

Git 2.39 on macOS contains a buggy `grep` implementation which, among
other things, fails to interpret the metasequence `\s` in extended regex
mode as space characters and instead interprets it as the literal `s`
character. To avoid this issue, this commit now uses `-P` instead of
`-E` when calling `git grep`, forcing use of PCRE instead.
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.
This is the async analog of 'rocket_sync_db_pools', rewritten to be
cleaner, leaner, easier to maintain and extend, and better documented.
Resolves#1117.
Resolves#1187.
Previously, we ran each doctest in core many times, once for each
individually enabled feature. This took a long time and consumed an
inordinate amount of resources for no gain: we already run each test
when we enable all features. Instead, emulate a 'cargo check' for
doctests by passing '--no-run' to rustdoc via an environment variable.
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.
This has the following nice benefits:
* The 'Uuid' wrapper type is gone.
* 'Uuid' implements 'UriDisplay', 'FromUriParam'.
* The 'serialization' example merges in 'uuid'.
Resolves#1299.
The 'SpaceHelmet' fairing is now called 'Shield'. It features the
following changes and improvements:
* Headers which are now ignored by browsers are removed.
* 'XssFilter' is no longer an on-by-default policy.
* A new 'Permission' policy is introduced.
* 'Shield' is attached to all 'Rocket' instances by default.
* Default headers never allocate on 'Clone'.
* Policy headers are rendered once and cached at start-up.
* Improved use of typed URIs in policy types.
This has the following nice benefits:
* The 'JsonValue' wrapper type is gone.
* 'Local{Request, Response}' natively support JSON/MessagePack.
* The 'json' and 'msgpack' limits are officially recognized.
* Soon, Rocket application will not require an explicit 'serde' dep.
This marks the beginning of the end of 'rocket_contrib'.
This allows us to test all of the "core" crates (and the guide) by
testing the root workspace, and all of the examples by testing in the
examples workspace.
Prior to this commit, it was not possible to test Rocket crates in
production mode without setting a global secret key or bypassing secret
key checking - the testing script did the latter. The consequence is
that it became impossible to test secret key related failures because
the tests passed regardless.
This commit undoes this. As a consequence, all tests are now aware of
the difference between debug and release configurations, the latter of
which validates 'secret_key' by default. New 'Client::debug()' and
'Client::debug_with()' simplify creating an instance of 'Client' with
configuration in debug mode to avoid undesired test failures.
The summary of changes in this commit are:
* Config 'secret_key' success and failure are now tested.
* 'secret_key' validation was moved to pre-launch from 'Config:from()'.
* 'Config::from()' only extracts the config.
* Added 'Config::try_from()' for non-panicking extraction.
* 'Config' now knows the profile it was extracted from.
* The 'Config' provider sets a profile of 'Config.profile'.
* 'Rocket', 'Client', 'Fairings', implement 'Debug'.
* 'fairing::Info' implements 'Copy', 'Clone'.
* 'Fairings' keeps track of, logs attach fairings.
* 'Rocket::reconfigure()' was added to allow modifying a config.
Internally, the testing script was refactored to properly test the
codebase with the new changes. In particular, it no longer sets a rustc
'cfg' to avoid secret-key checking.

Fixes#1564.
This commit completely overhauls Rocket's configuration systems, basing
it on the new Figment library. It includes many breaking changes
pertaining to configuration. They are:
* "Environments" are replaced by "profiles".
* 'ROCKET_PROFILE' takes the place of 'ROCKET_ENV'.
* Profile names are now arbitrary, but 'debug' and 'release' are given
special treatment as default profiles for the debug and release
compilation profiles.
* A 'default' profile now sits along-side the meta 'global' profile.
* The concept of "extras" is no longer present; users can extract any
values they want from the configured 'Figment'.
* The 'Poolable' trait takes an '&Config'.
* The 'secrets' feature is disabled by default.
* It is a hard error if 'secrets' is enabled under the 'release'
profile and no 'secret_key' is configured.
* 'ConfigBuilder' no longer exists: all fields of 'Config' are public
with public constructors for each type.
* 'keep_alive' is disabled with '0', not 'false' or 'off'.
* Inlined error variants into the 'Error' structure.
* 'LoggingLevel' is now 'LogLevel'.
* Limits can now be specified in SI units: "1 MiB".
The summary of other changes are:
* The default config file can be configured with 'ROCKET_CONFIG'.
* HTTP/1 and HTTP/2 keep-alive configuration is restored.
* 'ctrlc' is now a recognized config option.
* 'serde' is now a core dependency.
* TLS misconfiguration errors are improved.
* Several example use '_' as the return type of '#[launch]' fns.
* 'AdHoc::config()' was added for simple config extraction.
* Added more documentation for using 'Limits'.
* Launch information is no longer treated specially.
* The configuration guide was rewritten.

The user-facing changes effected by this commit are:
* The 'http::Cookies<'_>' guard is now '&http::CookieJar<'_>'.
* The "one-at-a-time" jar restriction is no longer imposed.
* 'CookieJar' retrieval methods return 'http::CookieCrumb'.
* The 'private-cookies' feature is now called 'secrets'.
* Docs flag private cookie methods with feature cfg.
* Local, async request dispatching is never serialized.
* 'Client::cookies()' returns the tracked 'CookieJar'.
* 'LocalResponse::cookies()' returns a 'CookieJar'.
* 'Response::cookies()' returns an 'impl Iterator'.
* A path of '/' is set by default on all cookies.
* 'SameSite=strict' is set by default on all cookies.
* 'LocalRequest::cookies()' accepts any 'Cookie' iterator.
* The 'Debug' impl for 'Request' prints the cookie jar.
Resolves#1332.
* body_string_wait and body_bytes_wait are removed; use `.await` instead
* `dispatch()` is now an async fn and must be .await-ed
* Add `#[rocket::async_test]` macro, similar in purpose to `tokio::test`
* Tests now use either `rocket::async_test(async { })` or
`#[rocket::async_test]` in order to `.await` the futures returned
from `dispatch()` and `body_{string,bytes}()`
* Update 'test.sh' to reflect the tests that should be passing.
Broken:
* Cloned dispatch and mut_dispatch() with a live previous response now both fail, due to a (partial) check for mutable aliasing in LocalRequest.
* Some tests are still failing and need example-specific changes.
