Order of response frames

[ioquatix]

Hello, thanks for your help.

Async::HTTP::Protocol::HTTP2::Server new write_frame: class=HTTP::Protocol::HTTP2::SettingsFrame flags=0 length=24
Async::HTTP::Protocol::HTTP2::Server new read_frame: class=HTTP::Protocol::HTTP2::SettingsFrame flags=0 length=6
6 > 16383
Async::HTTP::Protocol::HTTP2::Server new write_frame: class=HTTP::Protocol::HTTP2::SettingsFrame flags=1 length=0
Async::HTTP::Protocol::HTTP2::Server new read_frame: class=HTTP::Protocol::HTTP2::SettingsFrame flags=1 length=0
0 > 16383
Async::HTTP::Protocol::HTTP2::Server open read_frame: class=HTTP::Protocol::HTTP2::HeadersFrame flags=4 length=15
15 > 1048576
Async::HTTP::Protocol::HTTP2::Server open write_frame: class=HTTP::Protocol::HTTP2::HeadersFrame flags=4 length=37
Async::HTTP::Protocol::HTTP2::Server open write_frame: class=HTTP::Protocol::HTTP2::DataFrame flags=0 length=11
Async::HTTP::Protocol::HTTP2::Server open write_frame: class=HTTP::Protocol::HTTP2::DataFrame flags=1 length=0
Async::HTTP::Protocol::HTTP2::Server open read_frame: class=HTTP::Protocol::HTTP2::DataFrame flags=1 length=1048577
1048577 > 1048576
Async::HTTP::Protocol::HTTP2::Server open write_frame: class=HTTP::Protocol::HTTP2::GoawayFrame flags=0 length=48

I am running

x_x > ./h2spec --host localhost --port 9292 --tls http2/4.2/2
Hypertext Transfer Protocol Version 2 (HTTP/2)
  4. HTTP Frames
    4.2. Frame Size
      × 2: Sends a large size DATA frame that exceeds the SETTINGS_MAX_FRAME_SIZE
        -> The endpoint MUST send an error code of FRAME_SIZE_ERROR.
           Expected: GOAWAY Frame (Error Code: FRAME_SIZE_ERROR)
                     RST_STREAM Frame (Error Code: FRAME_SIZE_ERROR)
                     Connection closed
             Actual: DATA Frame (length:0, flags:0x01, stream_id:1)

This happens because I send a response before reading the request data, because that response does not require request body.

It seems like h2spec should be capable of consuming valid frames until finally GOAWAY, RST_STREAM, etc is received. WDYT?
