How to set up a timeout for TLS hasdshake

[josecelano]

Relates to:

• TLS handshake timeout (Fix #37) #39
• Give more control on connection tasks #29 (comment)_

I'm using axum-server ina couple of projects and I would like to add a timeout for the TLS handshake.

I've seen that that feature was added here: #39. However, It seems the AddrIncomingConfig was removed. I don't see any example or documentation to set the tcp_keepalive duration in the latest version. Was that feature removed @programatik29?

It seems it was removed on the migration to Hyper 1.0..

I'm trying to determine how to set the timeout with the new version. It seems Hyper 1.0 supports adding the timeout.

I have been able to make at least Hyper panic with;

let mut server = axum_server::from_tcp(socket);
server.http_builder().http1().header_read_timeout(Duration::from_secs(5));
server.http_builder().http2().keep_alive_timeout(Duration::from_secs(5));

server
    .handle(handle)
    .serve(router.into_make_service_with_connect_info::<std::net::SocketAddr>())
    .await
    .expect("Axum server crashed.")

The panic message:

thread 'tokio-runtime-worker' panicked at /home/josecelano/.cargo/registry/src/index.crates.io-6f17d22bba15001f/hyper-1.2.0/src/common/time.rs:73:32:
timeout `header_read_timeout` set, but no timer set
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I guess there is still something missing. I would appreciate an example of how you can set it up. In the meantime, I would keep trying. If I find the solution, I will open a PR with a new example.

I've managed to remove the panic with the following:

let mut server = axum_server::from_tcp(socket);

server.http_builder().http1().timer(TokioTimer::new());
server.http_builder().http1().header_read_timeout(Duration::from_secs(5));
server.http_builder().http2().keep_alive_timeout(Duration::from_secs(5));

server
    .handle(handle)
    .serve(router.into_make_service_with_connect_info::<std::net::SocketAddr>())
    .await
    .expect("Axum server crashed.")

But it's not working.

I have created an example here:

https://github.com/josecelano/axum-server-timeout

I've only been able to set a timeout for sending the headers with header_read_timeout. But I want the server to close the connection if the client does not send any requests.

I've updated the example with the @programatik29's patch. It works partially because it closes the connection, but it does not return a 408 Request Timeout like ActixWeb.
