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.

Sergio Benitez 12308b403f Add '#[rocket::launch]' attribute.
The attribute is applied everywhere it can be across the codebase and is
the newly preferred method for launching an application. This commit
also makes '#[rocket::main]` stricter by warning when it is applied to
functions other than 'main'.

Jeb Rosen bc1b90cbdb Add '#[rocket::main]' attribute and make 'launch()' an 'async fn'.
'#[rocket::main]' works like '#[rocket::async_test]', but it uses
tokio's multithreaded scheduler.

Jeb Rosen e72058de81 Add 'config()' and 'state()' functions directly to 'Rocket' for convenience. 2020-07-11 09:24:29 -07:00
Jeb Rosen b0238e5110 Make 'Fairing::on_attach()' async.
This transitively requires that 'Rocket::inspect()', 'Client::new()',
and 'Client::untracked()' also become async.

Jeb Rosen dea940c7a8 Defer execution of operations on 'Rocket' until their effects will be
observed.

This is a prerequisite for async on_attach fairings. 'Rocket' is now a
builder wrapper around the 'Manifest' type, with operations being
applied when needed by 'launch()', 'Client::new()', or 'inspect()'.
'inspect()' returns an '&Manifest', which now provides the methods that
could be called on an '&Rocket'.

Sergio Benitez 48c333721c Use 'async_trait' for 'Fairing' trait.
Also re-exports the 'async_trait' attribute from 'rocket'.

Michael Howell c9d0af09d6 Use 'AsyncSeek' for sized bodies in 'Response's.
In order to avoid making 'ResponseBuilder::sized_body' an asynchronous
function, the seeking is deferred until finalization. 'finalize()' is
replaced with '.await', and 'ResponseBuilder::ok()' is an 'async fn'.

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.

Sergio Benitez 61f107f550 Reimplement route attribute as a proc-macro.
This commits also implement the query reform from #608. It also consists
of many, many breaking changes. Among them are:

  * Query parts in route paths use new query reform syntax.
  * Routing for queries is now lenient.
    - Default ranking has changed to reflect query reform.
  * Format routing matching has been fixed.
    - Routes with formats matching "accept" will always collide.
    - Routes with formats matching "content-type" require requests to
      have an equivalent content-type header to match.
    - Requests with imprecise content-types are treated as not having a
      content-type.
  * Generated routes and catchers respect visibility modifiers.
  * Raw getter methods from request were renamed and retooled.
    - In particular, the index parameter is based on segments in the
      route path, not dynamic parameters.
  * The method-based attributes no longer accept a keyed 'path'.
  * The 'rocket_codegen' crate is gone and will no longer be public.
  * The 'FormItems' iterator emits values of type 'FormItem'.
    - The internal form items' string can no longer be retrieved.
  * In general, routes are more strictly validated.
  * Logging from codegen now funnels through logging infrastructure.
  * Routing has been optimized by caching routing metadata.

Sergio Benitez f171dc9d09 Reorganize repository.
The directory structure has changed to better isolate crates serving
core and contrib. The new directory structure is:

  contrib/
    lib/ - the contrib library
  core/
    lib/ - the core Rocket library
    codegen/ - the "compile extension" codegen library
    codegen_next/ - the new proc-macro library
  examples/ - unchanged
  scripts/ - unchanged
  site/ - unchanged

This commit also removes the following files:

  appveyor.yml - AppVeyor (Rust on Windows) is far too spotty for use
  rustfmt.toml - rustfmt is, unfortunately, not mature enough for use

Finally, all example Cargo crates were marked with 'publish = false'.

Sergio Benitez 084481a84e Initial implementation of typed URIs.
This is a breaking change. All Rocket applications using code
generation must now additionally declare usage of the 'decl_macro'
feature.

Sergio Benitez 8183f63630 Remove lints and associated code from 'rocket_codegen'.
Rust's linting API is incredibly unstable, resulting in unnecessary
breakage to `rocket_codegen`. Rocket's lints are also not as
conservative as would be desired, resulting in spurious warnings. For
these reasons, this commit removes linting from `rocket_codegen`.

These lints will likely be reintroduced as part of a 'rocket_lints'
crate. Factoring the lints out to a separate crate means that lint
breakage can be dealt with by uncommenting the dependency instead of
waiting for a new release or backtracking nightlies. In the same vein,
it will likely improve stability of the 'rocket_codegen' crate.

Sergio Benitez b8ba7b855f Remove Session in favor of private cookies. New testing API.
Sessions
--------

This commit removes the `Session` type in favor of methods on the
`Cookies` types that allow for adding, removing, and getting private
(signed and encrypted) cookies. These methods provide a superset of
the functionality of `Session` while also being a minimal addition to
the existing API. They can be used to implement the previous `Session`
type as well as other forms of session storage. The new methods are:

  * Cookie::add_private(&mut self, Cookie)
  * Cookie::remove_private(&mut self, Cookie)
  * Cookie::get_private(&self, &str)

Resolves #20

Testing
-------

This commit removes the `rocket::testing` module. It adds the
`rocket::local` module which provides a `Client` type for local
dispatching of requests against a `Rocket` instance. This `local`
package subsumes the previous `testing` package.

Rocket Examples
---------------

The `forms`, `optional_result`, and `hello_alt_methods` examples have
been removed. The following example have been renamed:

  * extended_validation -> form_validation
  * hello_ranks -> ranking
  * from_request -> request_guard
  * hello_tls -> tls

Other Changes
-------------

This commit also includes the following smaller changes:

  * Config::{development, staging, production} constructors have been
    added for easier creation of default `Config` structures.
  * The `Config` type is exported from the root.
  * `Request` implements `Clone` and `Debug`.
  * `Request::new` is no longer exported.
  * A `Response::body_bytes` method was added to easily retrieve a
    response's body as a `Vec<u8>`.

Sergio Benitez 9b955747e4 Remove config global state. Use Responder::respond_to.
This commit includes two major changes to core:

  1. Configuration state is no longer global. The `config::active()`
     function has been removed. The active configuration can be
     retrieved via the `config` method on a `Rocket` instance.

  2. The `Responder` trait has changed. `Responder::respond(self)` has
     been removed in favor of `Responder::respond_to(self, &Request)`.
     This allows responders to dynamically adjust their response based
     on the incoming request.

Additionally, it includes the following changes to core and codegen:

  * The `Request::guard` method was added to allow for simple
    retrivial of request guards.
  * The `Request::limits` method was added to retrieve configured
    limits.
  * The `File` `Responder` implementation now uses a fixed size body
    instead of a chunked body.
  * The `Outcome::of<R: Responder>(R)` method was removed while
    `Outcome::from<R: Responder(&Request, R)` was added.
  * The unmounted and unmanaged limits are more cautious: they will only
    emit warnings when the `Rocket` receiver is known.

This commit includes one major change to contrib:

  1. To use contrib's templating, the fairing returned by
     `Template::fairing()` must be attached to the running Rocket
     instance.

Additionally, the `Display` implementation of `Template` was removed. To
directly render a template to a `String`, the new `Template::show`
method can be used.

Sergio Benitez 28a1ef0916 Fairings, v3.
Modifying the `Rocket` structure just before launch doesn't make sense for
several reasons: 1) those affects can't influence the launch, and 2) they won't
be observed in tests. Thus, an `Attach` fairing kind was added that ameliorates
these issues.

Sergio Benitez 9c9740f966 Fairings v2. 2017-05-14 21:46:01 -07:00
Sergio Benitez 1e5a1b8940 Remove 'testing' feature. Close stream on network error.
This is a breaking change.

The `testing` feature no longer exists. Testing structures can now be
accessed without any features enabled.

Prior to this change, Rocket would panic when draining from a network
stream failed. With this change, Rocket force closes the stream on any
error.

This change also ensures that the `Fairings` launch output only prints
if at least one fairing has been attached.
