Description

Hello!

I have an application which streams data using http1.1 and chunked transfer-encoding.

nginx is used as http1.1/http2 proxy. http1.1 is used to communicate with an upstream with proxy_buffering off.

When application aborts streaming the expected behavior is to get an error on client's side.

That works well with http1.1

$ curl --http1.1 -i localhost:8083
HTTP/1.1 200 OK
Server: nginx/1.25.3
Date: Wed, 14 Feb 2024 17:25:56 GMT
Content-Type: text/plain; charset=utf-8
Transfer-Encoding: chunked
Connection: keep-alive

Random Line 2: KwIrtX5B5h

Random Line 442: FDo6cv5f4h
Random Line 443:curl: (18) transfer closed with outstanding read data remaining

but works randomly with http2. It may hang, exit with zero code or with error

$ curl --http2-prior-knowledge -i localhost:8082
HTTP/2 200
server: nginx/1.25.3

curl: (92) HTTP/2 stream 0 was not closed cleanly: INTERNAL_ERROR (err 2)

Also tested with haproxy 2.9.4 which works stable

~$ curl --http2-prior-knowledge -i localhost:8081
HTTP/2 200
date: Wed, 14 Feb 2024 17:30:54 GMT

Random Line 442: 6m0PZcOe8C
curl: (92) HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8)

Earlier versions of haproxy have issues too.

Please fix if possible
