Description

Got error "connection closed before message completed" from hyper::server::server::new_svc when I make a request that's long (>60s), coming from:

https://github.com/hyperium/hyper/blob/d77c2599bc023b258b90a17f5b633c8b7b0cbd4b/src/server/server.rs#L765

I tried this code:

pub fn do_my_thing() -> impl Filter<Extract = (impl warp::Reply,), Error = warp::Rejection> + Clone {
	warp::path!("v0" / "do_my_thing")
		.and(warp::post())
		.and(warp::body::content_length_limit(1024 * 16))
		.and(warp::body::json())
		.and_then(do_my_thing_handler)
		.with(warp::log(LOG_TARGET))
		.recover(errors::handle_rejection)
}

// Then:
warp::serve(do_my_thing())

The thing is, the do_my_thing_handler can take anywhere from 2s to 90s. And when in takes too long (>60s when counting in my head), I don't get any response, and instead get the above error "connection closed before message completed".

On the client using Postman, I get Error: socket hang up. With curl, it's Empty reply from server

I expected to see this happen: [explanation]

Return the response in any case, when the handler takes 2s or 60s.

Instead, this happened: [explanation]

I get an error on my client:

• curl: 52 empty reply from server
• Postman: socket hang up

See logs (also see times).

The response is correct when my own handler does its job in less than 60s.

Other notes

I also checked hyperium/hyper#2136, but it seems like the other issue is more on the client side, e.g. using reqwest.

I have the same problem using reqwest

Encountering the same issue when using both reqwest and surf.
