chromium — Push stream opened for a push nobody allowed

Fail

Rejected, but with error 0x101 where the specification requires 0x108. The violation was detected; the code reported is wrong.

The client did something the clause forbids, or failed to do what it requires.

What was measured

Client

chromium — Chromium QUICHE, build 1223

Test

Push stream opened for a push nobody allowed — h-push-stream-unpromised

Clause

RFC 9114 §6.2.2 (MUST)

Class

correctness — Rejected something invalid, with the code the RFC names.

Required behaviour

Close the connection with H3_ID_ERROR. §6.2.2 does not require the push to have been promised first — the stream alone is enough: a client "MUST treat receipt of a push stream as a connection error of type H3_ID_ERROR when no MAX_PUSH_ID frame has been sent", and no client under test sends one. Distinct from the PUSH_PROMISE test, which puts the same violation in a frame on the control stream. This one opens the push stream itself, which a client has to recognise by its stream type before any frame inside it is read.

Reproduce it

The suite is the judge, so the reproduction is to point the same client at the same test and let the server report what it saw.

SESSION=$(curl -sX POST https://conformance.pqcrypta.com/session | jq -r .id)
# then drive chromium at the test URL and read the verdict:
curl -s https://conformance.pqcrypta.com/report/$SESSION.json | jq '.results["h-push-stream-unpromised"]'
