Anomaly type: response_stream
How each client answered
| Client | Version | Verdict | What happened |
|---|---|---|---|
| curl | libcurl/8.23.0 ngtcp2/1.25.0 | Fail | Objected at the QUIC layer (rejected at the QUIC layer with INTERNAL_ERROR) instead of signalling the HTTP/3 error. The violation was detected and rejected, which is the right instinct; §8.1 requires an HTTP/3 connection error to be carried in an application close, and this test names 0x200. A transport close carries no HTTP/3 code at all, so a peer has no way to learn what was wrong. |
| quinn | noq fork (189b0ed) | Pass | Rejected with the required error code 0x200. |
| aioquic | 1.3.0 (PyPI wheel) | Pass | Rejected with the required error code 0x200. |
| chromium | build 1248 | Pass | Rejected with the required error code 0x200. |
| quic-go | quic-go v0.61.0 (h1:9So2anK4Tp22) | Fail | rejected the field section with QPACK_DECOMPRESSION_FAILED, but as a stream error: it stopped the request stream and kept the connection open. The code is right and the scope is not -- RFC 9204 makes every decompression failure a connection error. |
| quiche | 0.30.0 (1c8e976) | Pass | Rejected with the required error code 0x200. |
| neqo | 0.31.1 (cac2b74) | Pass | Rejected with the required error code 0x200. |
| picoquic | 8162550 | Fail | Rejected, but with error 0x106 where the specification requires 0x200. The violation was detected; the code reported is wrong. |
| ngtcp2 | 3c23148 | Pass | Rejected with the required error code 0x200. |
| lsquic | 4.9.4 (2b30189) | Pass | Rejected with the required error code 0x200. |
| xquic | 2060a44 | Fail | Rejected, but with error 0x106 where the specification requires 0x200. The violation was detected; the code reported is wrong. |
| msquic | 2.7.0 (7e6525d) | Fail | Rejected, but with error 0x101 where the specification requires 0x200. The violation was detected; the code reported is wrong. |
| quico | 0.7.0 (npm) | Pass | Rejected with the required error code 0x200. |
What the clause requires
Close the connection with QPACK_DECOMPRESSION_FAILED (0x200). The static table has 99 entries, so index 200 refers to nothing, and §3.1 is explicit: "When the decoder encounters an invalid static table index in a field line representation, it MUST treat this as a connection error of type QPACK_DECOMPRESSION_FAILED." The static table needs no permission and never changes size, so unlike the dynamic-table tests this one applies to every client.
