Assertion in HQ Fatal: HQFrame.cc:295: failed assertion sizeof(buf) > len

I guess this is just because our HQ(H3) impl is not updated. |
|
See I use traffic_quic to download a large file(128MB). |
|
I think The current server implementation should detect HTTP version (0.9 or HQ) for interop and all requests from traffic_quic should go into the logic for 0.9 (any HQFrame should not be created). So I guess it failed to detect HTTP version and the frame parser is reading HTTP/0.9 request as HQ frames. You can fix it if you want, but I'm not going to make the detection perfect because it will be removed in a few months. |
|
Hmm. Let's keep this issue until the detection has been removed. |
|
Now, the detection is not used for HTTP/3. HTTP/0.9 still has the detection, but the data will be ignored when the detection failed. |
