Jeb Rosen 85761c08e3 Fix deprecation warning: 'tokio::runtime::Builder::num_threads' -> 'core_threads'. 2020-07-11 09:24:29 -07:00
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'.

 2020-07-11 09:24:29 -07:00
Jeb Rosen ea06878581 Update 'hyper', 'futures-*-preview', and 'tokio-*' dependencies. 
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.

 2020-07-11 09:24:28 -07:00
Jeb Rosen af36f299c6 Fix ordering of messages in a UI test. 2020-07-11 09:24:28 -07:00
Jeb Rosen 523c6099fb Replace use of 'hyper::AddrIncoming' with a Listener API and implement TLS. 
Types can now implement the new 'Listener' trait, which means they can
report the address they are listening on and asynchronously accept
connections. 'Connection's are read/write streams that can additionally
report the remote address.

Listener is implemented for 'tokio_net::tcp::TcpListener' and for
the new 'rocket_http::tls::TlsListener' based on 'tokio-rustls'.

The new private function 'Rocket::listen_on()' now does the main setup
for launch and is generic over a Listener. In the future, a more refined
version of the API can be exposed so that applications can implement
their own listeners.

 2020-07-11 09:24:28 -07:00
Jeb Rosen 047b1620f9 Update pinned hyper and tokio versions. 2020-07-11 09:24:28 -07:00
Jacob Pratt 05426881b0 Use 'File' from 'async_std' instead of from 'tokio'. 
Additionally pin tokio to '=0.2.0-alpha.2'; before this change cargo
selects '0.2.0-alpha.3' which hyper does not compile against.
 2020-07-11 09:24:28 -07:00
Jeb Rosen 1f0577bfc5 Update remaining examples for async. 2020-07-11 09:24:28 -07:00
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.

Jacob Pratt a87e1577aa Add 'Rocket::spawn_on' to spawn a server on a user-provided (tokio) runtime. 2020-07-11 09:24:28 -07:00
Jacob Pratt e44c5896b8 Remove stabilized 'async_await' feature gate and update the minimum nightly version. 2020-07-11 09:24:28 -07:00
Jeb Rosen af95129590 Use futures 0.3-compatible hyper and tokio and the tokio runtime instead 
of futures-rs executor.

Despite this change, using body_bytes_wait on (for example) a File will
still fail due to tokio-rs/tokio#1356.
