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.
Resolves#1543.
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.
Resolves#852.
Resolves#209.
Closes#1404.
Closes#652.
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.
