Response End events were only triggered after polling the trailers of
a response, but when the Response is given to a hyper h1 server, it
doesn't know about trailers, so they were never polled!
The fix is that the `BodyStream` glue will now poll the wrapped body for
trailers after it sees the end of the data, before telling hyper the
stream is over. This ensures a ResponseEnd event is emitted.
Includes a proxy telemetry test over h1 connections.
The proxy will now try to detect what protocol new connections are
using, and route them accordingly. Specifically:
- HTTP/2 stays the same.
- HTTP/1 is now accepted, and will try to send an HTTP/1 request
to the target.
- If neither HTTP/1 nor 2, assume a TCP stream and simply forward
between the source and destination.

* proxy: implement Async{Read,Write} extra methods for Connection
Closes#130Closes#131
* Proxy: Use production config parsing in tests
Previosuly the testing code for the proxy was sensitive to the values
of environment variables unintentionally, because `Config` looked at
the environment variables. Also, the tests were largely avoiding
testing the production configuration parsing code since they were
doing their own parsing.
Now the tests avoid looking at environment variables other than
`ENV_LOG`, which makes them more resilient. Also the tests now parse
the settings using the same code as production use uses.
I validated this manually.
We’ve built Conduit from the ground up to be the fastest, lightest,
simplest, and most secure service mesh in the world. It features an
incredibly fast and safe data plane written in Rust, a simple yet
powerful control plane written in Go, and a design that’s focused on
performance, security, and usability. Most importantly, Conduit
incorporates the many lessons we’ve learned from over 18 months of
production service mesh experience with Linkerd.
This repository contains a few tightly-related components:
- `proxy` -- an HTTP/2 proxy written in Rust;
- `controller` -- a control plane written in Go with gRPC;
- `web` -- a UI written in React, served by Go.
