The new benchmarks use routes from real-world project. This is much more
realistic than the previous benchmarks.
The new benchmarks use `criterion` and exist in their own Cargo project.
This surfaced a dormant concurrency related issue. Prior to this commit,
the router used `routed_segments()` to retrieve the path segments of the
request. This was okay as there was no route in the request, and matched
segments were retrieved eagerly.
This commit makes segment matching lazy, so no matching occurs if
unnecessary. Between two matches, a `route` is atomically set of
`Request`. This is now visible in `routed_segments()`, which should not
have considered the current route in the first place. This was fixed.
While offering some utility, the lifetime did not carry its weight, and
in practice offered no further ability to borrow. This greatly
simplifies request guard implementations.
Previously, an `rx` lock was held for the entirety of the check period,
effectively making request handling serial. The implementation also held
a `write` lock to templating context while an expensive user-callback
was called, limiting template-related concurrency during that period.
This was changed so no lock is held during that period and a write-lock
is held only for the duration of the context field write.
This prevents printing a secret key warning if a secret key was
generated, as is done by Rocket itself. This does not change any
behaviors in non-debug profiles.
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.
