To the Rust teams, Rust's contributors, Rocket's contributors, the
entire Rust and Rocket communities, my colleagues at Stanford and
beyond, and Jeb: thank you all. Sincerely.
To the next ~4 years of Rocket!
Closes#19.
Prior to this commit, codegen used 'Span' information to generate a
unique id for a given route. This commit changes the id generation to
instead use 1) the route's name and path, 2) a an per-generation
atomically increasing ID, and 3) the ids of the process/thread the
proc-macro is running in. Together, these values should provide a unique
id for a given route, even in the face of the reused processes and
threads, while also removing the dependence on unstable Span features.
Fixes#1373.
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.

This is largely an internal change. Prior to this commit, the 'Manifest'
type, now replaced with the 'Cargo' type, robbed responsibility from the
core 'Rocket' type. This new construction restores the previous
responsibility and makes it clear that 'Cargo' is _only_ for freezing,
and representing the stability of, Rocket's internal state.
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.
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'.
Prior to this commit, codegen emitted tokens containing bare types like
'Result' and 'Box' as well as presumed imported variants such as 'None'
and 'Ok'. However, users are free to shadow these, and if they do, the
generated code will fail to compile, or worse, be incorrect. To avoid
this, this commit makes all references to these core types and imports
absolute.
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.
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'.
* Update 'tokio', 'tokio-rustls', and 'hyper'.
* Remove unused dependencies on some `futures-*` crates.
* Rework 'spawn_on', which is now 'serve'.
* Simplify Ctrl-C handling.
Use I/O traits and types from 'tokio-io' as much as possible.
A few adapters only exist in futures-io-preview and use
futures-tokio-compat as a bridge for now.
* 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.
This is required to be able to do anything useful with the body in the
outgoing response. Request fairings do not appear to need to be async
as everything on Data that returns a future moves self and on_request only
gets &Data, but the same change in this commit should work for on_request
if desired.
Every code example is now fully runnable and testable. As a result, all
examples are now tested and include imports. Relevant imports are shown
by default. Code examples can be expanded to show all imports.
Fixes#432.

This commit introduces the sealed `UriPart` marker trait as well as the
implementing `Path` and `Query` marker types, allowing for parts of a
URI to be distinguished at the type level. Consequently, `UriDisplay`
has been parameterized with `P: UriPart`, creating `UriDisplay<Path>`
and `UriDisplay<Query>`. The effect of this change is improved type
safely for URI rendering as well as the ability to omit rendering values
in query parts via `Option` and `Result`.
The `UriDisplay` derive was replaced by `UriDisplayQuery` and
`UriDisplayPath` which derive implementations for `UriDisplay<Path>`
and `UriDisplay<Query>`, respectively.
This commit also works around a rustdoc visibility issue by creating a
hidden `http::private` module.
Finally, this commit also removes the now vestigial use of the
`rustc_private` feature in codegen.
Fixes#827.
Prior to this change, Rocket emitted "white" text in much of its logging
output. On terminals with light backgrounds, the text was nearly
illegible. This PR stops using white coloring altogether, opting instead
to use the terminal's default color albeit with bold styling. On dark
terminals, this will likely be a light color, and on light terminals,
this will likely be a dark color. The end result is that Rocket's
logging output should be readable everywhere.
Resolves#639.
