How each client answered
| Client | Version | Verdict | What happened |
|---|---|---|---|
| curl | ngtcp2/1.11.0 | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
| quinn | noq fork | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
| aioquic | 1.3.0 | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
| chromium | build 1223 | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
| quic-go | quic-go v0.61.0 | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
| quiche | 0.30.0 | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
| neqo | 0.31.1 | Inconclusive | The run did not exercise this test: the client advertised SETTINGS_QPACK_MAX_TABLE_CAPACITY of 0 and SETTINGS_QPACK_BLOCKED_STREAMS of 0, which forbid the server's encoder from using the dynamic table at all. |
What the clause requires
Hold the field section, apply the insertions when they arrive on the encoder stream, and complete the request. §2.2.1 makes a section whose Required Insert Count exceeds the decoder's Insert Count a blocked stream — something to be waited on, not an error. Only run when the client advertised both a table capacity and at least one blocked stream; §2.1.2 forbids the encoder from blocking more streams than the decoder promised to support, so a client that permits none cannot be tested on this.
Judged against RFC 9204.
