Fix authorship, license information. (#55) 
* Fix authorship, license information.

I *thought* I had done a sed pass over the Cargo defaults when doing
repository initialization, but I guess I missed it or something.
Anyways, fixed now.

Initial tower-based peer implementation. (#17) 
Add a tower-based peer implementation.  

Tower provides middleware for request-response oriented protocols, while Bitcoin/Zcash just send messages which could be interpreted either as requests or responses, depending on context.  To bridge this mismatch we define our own internal request/response protocol, and implement a per-peer event loop that scans incoming messages and interprets them either as requests from the remote peer to our node, or as responses to requests we made previously.  This is performed by the `PeerService` task, and a corresponding `PeerClient: tower::Service` can send it requests.  These tasks are themselves created by a `PeerConnector: tower::Service` which dials a remote peer and performs a handshake.

Henry de Valence c8a3d47b56 Use tracing::instrument and monitor for messages. 2019-09-23 22:17:12 -04:00
Henry de Valence 15ca12a2f5 Add a `connect` command for testing. 
With `./src/zcashd -debug=net -logips=1`:
```
2019-09-19 15:24:38 Added connection to 127.0.0.1:35932 peer=1
2019-09-19 15:24:38 connection from 127.0.0.1:35932 accepted
2019-09-19 15:24:38 socket closed
2019-09-19 15:24:38 disconnecting peer=1
```

With `RUST_LOG="trace"`, `cargo run connect`:
```

Henry de Valence df7801d623 Temporarily change hyper to git version. 
This avoids some crate selection conflicts, but makes some futures
extension traits fall out of order?  This seems to be an issue with
`pin-project` resolved in the git branch of `hyper` (but not yet
released).

Deirdre Connolly 162b37fe8d Tracing endpoint (#3) 
* Add a TracingConfig and some components

Co-authored-by: Deirdre Connolly <deirdre@zfnd.org>

* Restructure, use dependency injection, initialize tracing

* Start a placeholder loop in start command

* Add hyper alpha.1, bump tokio to alpha.4

* Hello world endpoint using async/await from hyper 0.13 alpha

Also cleaned up some linter messages.

Co-authored-by: Henry de Valence <hdevalence@hdevalence.ca>

* Update to tracing_subscriber 0.1

* fmt

* add rust-toolchain

* Remove hyper::Version import

* wip: start filter_handler impl

* Add .rustfmt.toml

* rustfmt

* Tidy up .rustfmt.toml

* Add filter reloading handling.

* bump toolchain

* Remove generated hello world acceptance tests.

These test the behaviour of the autogenerated binary and work as examples of
how to test the behaviour of abscissa binaries.  Since we don't print "Hello
World" any more, they fail, but we don't yet have replacement behaviour to add
tests for, so they're removed for now.

* Clean up config file handling with Option::and_then.
