test: reproduce downstream H1 whole-header lifetime gap - #71
Conversation
📝 WalkthroughWalkthroughUnix 전용 통합 테스트가 새 연결과 keep-alive 연결에서 HTTP/1 불완전 헤더의 전체 수명을 검증합니다. 테스트는 slow-drip 요청의 종료, upstream 전달 차단, 게이트웨이 상태 유지, 공격자 제어 헤더의 로그 미기록을 확인합니다. ChangesHTTP/1 요청 헤더 수명 검증
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~45 minutes Severity of issue fixed: Medium Merge Risk: 🟡 Moderate · up to Production behavior is unchanged, but the new integration tests can hang CI indefinitely when trace output fills the stderr pipe. Drain stderr concurrently before merging. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Full details: Linked Issues checkExplanation PR은 실시간 downstream HTTP/1 소켓, 불완전 헤더의 slow-drip, 새 연결 및 keep-alive 재사용 경로를 대상으로 RED 테스트를 추가합니다. 그러나 재사용 연결이 실제로 유지되었음을 확인하기 전에 EOF를 성공적인 enforcement로 허용할 수 있다는 인과성 문제가 남아 있습니다. 또한 PR은 monotonic whole-header deadline 구현을 포함하지 않습니다.

High — The reused-connection case can pass after a pre-existing downstream close. In that case, the fixture does not exercise acquisition of an incomplete header on a sequentially reused keep-alive connection. It accepts closure of the first-request connection as a pass. Before starting the second-header timer, require an active persistent downstream connection. At minimum, reject The source review confirms that the composition root does not enable H1 pipelining. The origin monitor also fails closed when its sender disconnects. I did not run the test because this inspection environment does not permit repository execution. ✅ Action performedReview finished.

- Around line 374-383: Start draining the gateway stderr immediately after
process creation in both affected tests, including
reused_keepalive_slow_drip_is_terminated_by_whole_header_budget, by moving the
captured pipe into a background thread that continuously reads and returns the
logs. After terminate_gateway completes, join the drain thread and use its
collected output instead of reading stderr afterward.

Exact-current owner technical review on 21e5ef1be81f7f873122ad36ceca5ddf6939a343: I re-read the one-path delta after the valid stderr-pipe finding was repaired. The new drain_gateway_stderr starts immediately after each child spawn, continuously consumes the captured trace stream, and joins only after SIGTERM/reap, so the prior pipe-capacity deadlock surface is removed without changing the H1 traffic/timing oracle or attacker-marker exclusion. The reused-origin monitor remains fail-closed on channel disconnect and this composition root still makes no pipelined-prefix claim because H1 pipelining is not enabled. Current exact CI independently reconfirms the intended supplier RED only: both fresh and sequential-reuse slow-drip paths survive ~2.546s beyond the 1.5s whole-header budget while formatting/compilation and preceding targets pass; load/OCI and bounded-origin capacity are GREEN. No additional actionable writer-safe source/test/DDD finding found in the current diff. This COMMENT is technical evidence only, not approval or release credit; Supply Chain remains independently nonterminal at this review timestamp.

The compiled generic gateway is exercised through real loopback TCP. The test keeps the incomplete request far below parser byte/count ceilings and sends progress every 100 ms, distinguishing whole-header lifetime from #43 parser admission and ordinary per-read inactivity. It declares a 1.5 s whole-header acceptance budget with 0.5 s enforcement grace and a 2.5 s evidence bound; these are test values, not a runtime/config field.
A fresh connection and a sequentially reused HTTP/1.1 keep-alive connection must both terminate an incomplete second header despite continued sub-timeout progress, without origin admission. The reused case first completes
/firstthrough the real origin and consumes exact HTTP 200/body before starting the second header. This composition root does not enable Pingora H1 pipelining; pipelined-prefix lifetime remains a separate future contract.Current exact execution

mainremains exact702f69015e53f7244d6ad2e743de571d859a70a4; lightweightrefs/tags/0.9.0points directly to the same commit. GitHub Release Pingora 0.9.0 was published at2026-09-09T23:34:48Z(2026-09-10 08:34:48 KST), is not a prerelease, has no attached assets, and is reported asimmutable:false.Fresh released-source inspection still shows H1 request acquisition governed by per-read relative timeout semantics: successful partial reads can return to the outer request-parse loop, and no supported monotonic whole-request-header deadline is exposed. Therefore publication changes release-state evidence but does not change this RED.
cloudflare/pingora#447remains the canonical supplier owner path.GREEN for #45 requires a maintainer-integrated monotonic whole-header capability in a later release-qualified supplier identity, followed by an explicit positive versioned gateway Admin Config transition only if CWL exposes the operator control, such that these unchanged fresh+reused paths terminate despite continued progress while readiness, log privacy and recovery remain healthy. HTTP/2/H3 and parser byte/count admission remain separate contracts.
Keep Draft. No protected merge, release, canary/cutover, rollback or legacy-removal credit is claimed.
