Sergio Benitez 9d20c57d91 Allow named field generics in 'UriDisplay' derive. 2021-07-01 06:02:40 -07:00
Sergio Benitez 2727d7bb7b Automatically discover 'Responder' generic bounds.
This commit presents and applies a new technique for bounding type
generics in derives. In short, for a generic `T` used in a field type of
`Field<T>`, where an eventual bound of `Responder` required, the derive
generates a bound of `Field<T>: Responder`. This removes the need for
any manually provided bounds while simultaneously allowing more
structures to typecheck. For example, generics in header components are
now fully supported.

Sergio Benitez 63e6845386 Revamp 'Response', 'Body' types.
This is a breaking change for many consumers of the 'Response' and all
consumers of the 'Body' API. The summary of breaking changes is:

  * 'Response::body()', 'Response::body_mut()' are infallible.
  * A 'Body' can represent an empty body in more cases.
  * 'ResponseBuilder' is now simply 'Builder'.
  * Direct body read methods on 'Response' were removed in favor of
    chaining through 'body_mut()': 'r.body_mut().to_string()'.
  * Notion of a 'chunked_body' was removed as it was inaccurate.
  * Maximum chunk size can be set on any body.
  * 'Response' no longer implements 'Responder'.

A few bugs were fixed in the process. Specifically, 'Body' will emit an
accurate size even for bodies that are partially read, and the size of
seek-determined bodies is emitted on HEAD request where it wasn't
before. Specifics on transport were clarified, and 'Body' docs greatly
improved as a result.

Sergio Benitez 4e06ee64aa Test 'secret_key' validation, now on pre-launch.
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.

Sergio Benitez 5d9035ddc1 Keep an op-log for sync 'CookieJar'.
In brief, this commit:

  * Updates to the latest upstream 'cookie', fixing a memory leak.
  * Make changes to 'CookieJar' observable only through 'pending()'.
  * Deprecates 'Client::new()' in favor of 'Client::tracked()'.
  * Makes 'dispatch()' on tracked 'Client's synchronize on cookies.
  * Makes 'Client::untracked()' actually untracked.

This commit updates to the latest 'cookie' which removes support for
'Sync' cookie jars. Instead of relying on 'cookie', this commit
implements an op-log based 'CookieJar' which internally keeps track of
changes. The API is such that changes are only observable through
specialized '_pending()' methods.

Sergio Benitez 03127f4dae Add blocking variant of 'local'.
This commit adds the 'local::blocking' module and moves the existing
asynchronous testing to 'local::asynchronous'. It also includes several
changes to improve the local API, bringing it to parity (and beyond)
with master. These changes are:

  * 'LocalRequest' implements 'Clone'.
  * 'LocalResponse' doesn't implement 'DerefMut<Target=Response>'.
    Instead, direct methods on the type, such as 'into_string()', can
    be used to read the 'Response'.
  * 'Response::body()' returns an '&ResponseBody' as opposed to '&mut
    ResponseBody', which is returned by a new 'Response::body_mut()'.
  * '&ResponseBody' implements 'known_size()` to retrieve a body's size,
    if it is known.

Sergio Benitez 2465e2f136 Make 'Responder' trait sync; fix its lifetimes.
In summary, this commit modifies 'Responder' so that:

  * ..it is no longer 'async'. To accommodate, the 'sized_body' methods
    in 'Response' and 'ResponseBuilder' are no longer 'async' and accept
    an optional size directly. If none is supplied, Rocket will attempt
    to compute the size, by seeking, before writing out the response.
    The 'Body' type was also changed to differentiate between its sized
    'Seek' and chunked body variants.

  * ..'&Request' gains a lifetime: 'r, and the returned 'Response' is
    parameterized by a new 'o: 'r. This allows responders to return
    references from the request or those that live longer.

Jeb Rosen b0238e5110 Make 'Fairing::on_attach()' async.
This transitively requires that 'Rocket::inspect()', 'Client::new()',
and 'Client::untracked()' also become async.

Sergio Benitez c0c6c79a7f Use 'async_trait' for 'Responder'.
Also:

  * Remove 'response::ResultFuture'.
  * Re-export 'tokio' and 'futures' from the crate root.
  * Make 'ResponseBuilder::sized_body()' and 'async fn'.
  * Remove the 'Future' implementation for 'ResponseBuilder'.
  * Add 'ResponseBuilder::finalize()' for finalizing the builder.

Jeb Rosen 560f0977d3 Revamp testing system for async.
* 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.
