Summary

Extends the cross-listener parity suite to exercise request/response bodies. Adds body-recording knobs to the spy plus three fixtures: buffered JSON, SSE streaming, and inbound overflow.

This would catch bugs such as:

  • Duplicate terminal-frame dispatch e.g. the framework calling last=true more than once per response
  • Silent zero: plugin observes empty body on the passthrough path.
  • Reassembled-content drift between extproc (buffered) and proxy (streamed) SSE paths

Snuck in a change to adapt tlsbridge.NewUpstreamClient test call sites to the two-arg signature from #677 (repairs a main build break blocking this PR's CI)

Tracked separately:

Explanation

The PR satisfies most coding requirements in [#937]. spyPlugin.Capabilities reports ReadsBody. Buffered JSON fixtures record request and response bytes for inbound and outbound listeners. The SSE fixture checks reassembled bytes and one terminal frame. The overflow fixture checks pre-pipeline refusal and status 413. The new fixtures do not configure WritesRequestBody or WritesResponseBody, call pctx.SetBody, or assert mutation replay. This leaves the required body-mutation coverage unmet.

Adds body-recording knobs to the spy infrastructure, a spyStreamingPlugin variant implementing StreamingResponder, and three new parity fixtures (buffered JSON, SSE, inbound overflow). The pipelineRefusedPreRun escape hatch and the expectedPluginEvents correctness anchors are both solid additions that close the shared-drop gap in the existing parity harness.

Finding: OnResponseFrame publishes via s.publish(pctx, "/resp-body/event", ...) but OnRequest publishes via s.publish(pctx, "/req-body/event", ...) — both are correct because SnapshotPlugins strips the /event suffix before populating SessionEvent.Plugins. The comment on line 41 (SessionEvent.Plugins[<name>/req-body]) is therefore accurate, but it's worth noting this relies on an implicit coupling to pipeline.PluginEventSuffix; using the constant directly (e.g. "/req-body" + pipeline.PluginEventSuffix) would make the convention explicit and prevent drift if the suffix ever changes.

The suffix "/req-body/event" (and "/resp-body/event" on line 134) works correctly because SnapshotPlugins strips pipeline.PluginEventSuffix before keying the result. Consider composing the suffix explicitly — e.g. "/req-body" + pipeline.PluginEventSuffix — so this convention is self-documenting and won't silently break if the constant's value changes.

Summary

Extends the cross-listener parity suite with body coverage: body-recording knobs on the spy, a spyStreamingPlugin implementing StreamingResponder, and three fixtures (buffered JSON, SSE, inbound overflow). The expectedPluginEvents anchor is the good idea here — it turns pairwise drift-catching into absolute correctness-checking. One of the three new fixtures doesn't get that protection, which is the blocking comment below.

Areas reviewed: Go (test-only, authbridge/authlib/listener/parity/)
Agent/IDE config (.claude/.vscode): none
Commits: 4 — 3 signed off; merge commit d605f45 unsigned (DCO is green because the app exempts merge commits, but CLAUDE.md asks for sign-off on all commits, and rebasing rather than merging would keep the branch history uniform — non-blocking)
CI: 24 pass, Spellcheck skipping

Verified

  • The plugin-event key scheme is correct, which is the non-obvious part: the spy publishes name + "/req-body/event", and SnapshotPlugins filters on PluginEventSuffix = "/event" (pipeline/extensions.go:52) and strips it, yielding name + "/req-body" — matching the fixtures.
  • Duplicate terminal-frame dispatch (claimed bug class 1) is genuinely caught: a second last=true increments terminals to 2 and republishes, failing TerminalFrames: 1. Silent-zero (class 2) is caught by the exact byte assertions.
  • Skipping WireStatus on the success path is necessary rather than an oversight — extprocWireStatus returns 0 there since extproc has no HTTP transport — and it is documented as such.
  • No nil-deref risk: finalizeObservation returns a synthesized non-nil observation for the refused case, so assertParity's obs == nilt.Fatalf does not fire on the overflow fixture.
  • observe still fails loudly on more than one matching event, so exactly-once recording stays pinned.

must-fixpipelineRefusedPreRun only permits a missing session event; nothing requires one.

So TestParity_InboundRequestBodyOverflow passes if both inbound listeners stop enforcing the 1 MiB cap: the pipeline runs, both listeners record, finalizeObservation stamps PipelineRan: true on both, and observationDiff falls through to the ordinary session-event comparison and agrees. A test named for overflow rejection would then be green with an unbounded body flowing through.

That is exactly the shared-drop failure mode expectedPluginEvents was added to close (see the "correctness anchors" comment in parity_test.go), but the mechanism doesn't reach this fixture — it has no expected events, and WireStatus is only ever compared pairwise, never against 413.

Two small changes close it:

  1. Here, assert the fixture's expectation rather than merely permitting it:
obs.PipelineRan = true
if f.pipelineRefusedPreRun {
    t.Errorf("fixture %q expected the listener to refuse before the pipeline, but an event was recorded", f.name)
}
  1. Add an expectedWireStatus int to fixture and check it in assertParity, so 413 is pinned rather than merely agreed on.

suggestion — Of the four bug classes the PR body claims, the uncovered one is the only one this suite is actually shaped to catch.

outboundListeners pairs extproc (maxBodySize = 1 << 20) with forwardproxy (maxBodySize = 10 << 20), so an outbound fixture with a body between the two caps (~2 MiB) would have extproc reject and forwardproxy accept — real cross-listener drift. This fixture runs inboundListeners, where both listeners are at 1 MiB, so it can't surface it.

I'd expect such a fixture to fail today. I verified the constants (extproc/server.go:32, reverseproxy/server.go:43, forwardproxy/server.go:56) and the listener pairings, but did not execute an outbound overflow case.

Either add it and file the divergence, or note in the PR body that the outbound cap gap is deliberate and out of scope — as written, the "Divergent request-body caps" bullet reads like a bug this PR guards against.

nit — The PR body claims this catches "frame-boundary drift between extproc buffered and proxy SSE streaming," but this comment correctly says the assertion is on cumulative bytes and that frame counts vary by listener — which is the right call, since boundaries legitimately differ between a buffered and a streamed path.

What's actually pinned is reassembled-content drift plus exactly-once terminal dispatch. Worth rewording the bullet so a future reader doesn't add a frame-count assertion believing it was intended.

Reviewing the three new commits (05e44113ddfb2f) that address prior CodeRabbit and human review feedback.

Changes since last pass

The author addressed the main CodeRabbit items and huang195's blocking comment. Specifically:

  1. pipelineRefusedPreRun flag + finalizeObservation — the escape hatch for the overflow fixture is well-scoped. finalizeObservation fails loudly when an event is missing without the opt-in, which is the right default. ✅
  2. expectedPluginEvents correctness anchor in assertParity — both body-JSON and SSE fixtures now anchor against exact expected plugin-event payloads before the pairwise comparison, closing the shared-drop gap. ✅
  3. Outbound ReadsBody fixture (TestParity_OutboundReadsBodyBufferedJSON) — resolves CodeRabbit's comment about the forward-proxy path being untested. ✅
  4. observationDiff PipelineRan / WireStatus gates — the early-return when !PipelineRan ensures overflow fixtures compare only the wire-level status, not session-event fields that don't exist. ✅
  5. contentType() helper propagated — all three driver paths (extproc, reverse-proxy, forward-proxy) now use f.contentType() instead of hardcoding application/json. ✅

Remaining note (non-blocking)

The PluginEventSuffix implicit coupling I flagged in the previous pass is still present — OnRequest builds its key as bodyReqStrippedSuffix + pipeline.PluginEventSuffix and OnResponseFrame does the same with bodyRespStrippedSuffix. The fixture expectation maps use the stripped form, which is correct. This is a style nit, not a bug — the constants are now at least defined in one place rather than inline, which is an improvement.

CI: 23 checks green; Verify module graph is tidy is still failing (pre-existing, unrelated to this diff). Spellcheck skipped (expected). DCO green. All substantive commits signed off; the merge commit d605f45 is unsigned but DCO exempts merge commits.

Verdict: the blocking issue from huang195's review (overflow fixture skipping correctness anchors, shared-drop blind spot) is resolved. The implementation is clean. Ready to merge pending the module-graph check or a maintainer waiver on that.

Re-review at 3ddfb2f

This push landed a few minutes after my previous review, so it likely crossed with it rather than responding to it. Notes on where things stand.

What changed here — both good

  • Suffix constants. bodyReqStrippedSuffix / bodyRespStrippedSuffix replacing the "/req-body/event" literals is behavior-neutral ("/req-body" + PluginEventSuffix reproduces the old literal exactly, and the fixtures key on the stripped form) and makes the two-halves relationship legible. Good answer to clawgenti's note on those lines.
  • TestParity_OutboundReadsBodyBufferedJSON. Real new coverage — forwardproxy's body path had none.

Still open

The must-fix from my last review is untoucheddrivers_test.go isn't in this commit, finalizeObservation is byte-identical, and there's no expectedWireStatus. TestParity_InboundRequestBodyOverflow still passes if both inbound listeners stop enforcing the 1 MiB cap. See the inline comment on drivers_test.go, which is still live.

On the outbound cap suggestion: the new outbound fixture exercises forwardproxy's body path, but with an 18-byte body — nowhere near the 1 MiB / 10 MiB boundary, so the cap divergence between extproc and forwardproxy is still uncovered. Not blocking; it's a scope call.

The two PR-body wording nits ("frame-boundary drift", "divergent request-body caps") are unchanged.

CI is red, but not because of this PR — please just re-run it

"Verify module graph is tidy" fails. Every failure line in the log has the same root cause:

github.com/maximhq/bifrost/core@v1.7.15: read "https://proxy.golang.org/.../v1.7.15.mod":
stream error: stream ID 33; INTERNAL_ERROR; received from peer

That's a transient proxy.golang.org HTTP/2 error. go mod tidy -diff couldn't resolve the graph, and the workflow surfaces any non-zero exit as go mod tidy would change authbridge/authlib/go.mod; run 'go mod tidy' in authbridge/authlib and commit — so the message is misleading here. Don't run go mod tidy; two test-file edits that add no imports cannot change the module graph. A re-run should clear it.

(Separately, and out of scope for this PR: that workflow conflating "tidy would change go.mod" with "tidy failed to run" is worth a follow-up — it turns any module-proxy blip into a false actionable error.)

This HEAD (3ddfb2f) has already been covered in my prior pass (see review PRR_kwDOQAi1188AAAABNf6jbQ). Posting a follow-up focused on the remaining open point from huang195's review.

huang195 correctly identifies that TestParity_InboundRequestBodyOverflow still has no expectedWireStatus anchor: if both inbound listeners stop enforcing the 1 MiB cap simultaneously, the fixture passes vacuously because assertParity only compares the two listeners against each other, and WireStatus in observationDiff is only checked when !PipelineRan — which is asserted via pipelineRefusedPreRun: true, so that path does run. However the specific wire status (413) is never pinned to a known value, so a regression that returns 200 from both would still pass. Adding an expectedWireStatus field to the fixture struct (checked in finalizeObservation when !PipelineRan) would close this. This is the one remaining must-fix before the blocking CHANGES_REQUESTED can be cleared.

suggestion: TestParity_InboundRequestBodyOverflow asserts that pipelineRefusedPreRun is true and that both listeners agree on WireStatus via observationDiff, but the expected wire status (413) is never pinned to a concrete value. Both listeners returning 200 would still pass parity. Consider adding an expectedWireStatus int field to fixture and asserting it inside finalizeObservation when !PipelineRan — this is the correctness-anchor equivalent of expectedPluginEvents for the refused path.

Reviewing the three new commits since my last pass (3ddfb2fff9e2ed).

Changes in this push

  • d3d7138:white_check_mark: Address review comments — parity test updates (signed)
  • 69366737 — merge main into parity-body-tests (merge commit, DCO exempt) — this pull brings in the expectedWireStatus field and the bidirectional pipelineRefusedPreRun check in finalizeObservation
  • ff9e2ed:bug: Update tls bridge client test usage — adapts 7 tlsbridge_integration_test.go and tunnelreason_integration_test.go call sites to NewUpstreamClient(pem, false) following a signature change on main (signed)

Blocking issue from huang195's review — resolved via merge

The must-fix (expectedWireStatus absent in TestParity_InboundRequestBodyOverflow, shared-regression blind spot) is now in the diff from the main merge: drivers_test.go gains the expectedWireStatus int field on fixture, the assertParity wire-status anchor loop, and the bidirectional pipelineRefusedPreRun guard in finalizeObservation (event-present-when-not-expected is now also a hard error). The overflow fixture has expectedWireStatus: 413. This is exactly the fix that was needed.

ff9e2ed — tlsbridge call-site update

The signature change NewUpstreamClient(pem) → NewUpstreamClient(pem, false) is mechanical and correct across all 7 sites. false matches the prior behavior (whatever the new bool controls, defaulting it off preserves existing semantics). No logic changes in test bodies.

CI at HEAD

All 24 checks green, Spellcheck skipped as expected, DCO green. The transient proxy.golang.org HTTP/2 failure huang195 flagged on Verify module graph is tidy cleared on the re-run — confirming it was the network blip, not a real tidy issue.

Remaining non-blocker

The PluginEventSuffix style nit (build the key from the constant rather than the concatenated literal) remains; it's cosmetic and not a reason to hold this.

Verdict: the blocking item is resolved. All prior review points are addressed. CI is clean. Ready to merge.

Re-review at ff9e2ed — the must-fix is closed

The blocking finding from my earlier review is resolved, and I verified both halves rather than taking the commit message for it:

  • finalizeObservation is now a strict expectation in both directions. A missing event without pipelineRefusedPreRun errors; an event present with pipelineRefusedPreRun set also errors ("the listener silently stopped enforcing the cap"). That closes the shared-drop hole.
  • expectedWireStatus pins 413 absolutely, checked against every listener in assertParity rather than only agreeing pairwise. So the failure mode I described — both inbound listeners stop enforcing the 1 MiB cap and return 200 — now fails on the wire-status anchor even if the phase filter misses the event.

Both PR-body wording nits were also addressed (the SSE bullet now says "reassembled-content drift", and the cap divergence is explicitly deferred to #987 rather than reading like a bug this PR guards against). Thanks for that.


⚠️ This PR is currently the only fix for a red main

Commit ff9e2ed ("Update tls bridge client test usage") isn't incidental cleanup — it repairs a build break on main. Verified:

Failing job Go CI (authlib) → Lint
Error vet: listener/forwardproxy/tlsbridge_integration_test.go:117:52: not enough arguments in call to tlsbridge.NewUpstreamClient
Cause #677 / 5d56f48f changed NewUpstreamClient to (extraRootsPEM []byte, insecure bool) but updated only tlsbridge/upstream_test.go and cmd/authbridge-proxy/main.go — it missed 6 call sites in listener/forwardproxy
First red commit 69b48de6 (the #677 merge)

The files have no build tag, so this is a plain go vet / compile failure in the forwardproxy test package. All six false arguments are the correct behavior-preserving value — notably in TestBridge_UnverifiableUpstream_FallsOpenToTunnel, whose whole premise requires upstream verification to stay enabled.

See the inline note on line 117 for the ask: either land this promptly, or cherry-pick ff9e2ed into a standalone fix: PR so main goes green without waiting on this review.


Also verified in this pass

  • The pipelineRefusedPreRun strict check genuinely bites. All three listeners emit SessionRequest-phase events (reverseproxy/server.go:426, extproc/server.go:243, forwardproxy/server.go:374), so a regression that ran the pipeline on an oversized body would record exactly at the phase observe is filtering for → non-nil → error. This is not dead code. It does mean the wantPhase argument is load-bearing rather than a placeholder — see the inline suggestion.
  • No nil-deref on the refused path. finalizeObservation returns a synthesized non-nil observation, so assertParity's obs == nil → t.Fatalf doesn't fire; and observationDiff short-circuits after WireStatus so the zero-valued session fields are never compared.
  • expectedPluginEvents is safe to omit on the refused fixture — the map is nil, so the anchor loop is a no-op rather than reporting spurious missing keys.
  • Duplicate terminal-frame dispatch is still caught: a second last=true bumps terminals to 2 and republishes over the same key, failing TerminalFrames: 1. Silent-zero is caught by the exact byte comparison. Both claimed bug classes hold.
  • omitempty on TerminalFrames is harmlesspublish only fires on last, so the count is always ≥ 1, and the request-body observation intentionally omits the field on both the expected and observed side.

note (not a defect — please just make sure this doesn't get lost)

This line and its five siblings are the fix for a currently-broken main, not test cleanup incidental to the parity work.

main tip bafeceb0 is red: Go CI (authlib) → Lint fails with

vet: listener/forwardproxy/tlsbridge_integration_test.go:117:52: not enough arguments in call to tlsbridge.NewUpstreamClient

#677 (5d56f48f) changed the signature to NewUpstreamClient(extraRootsPEM []byte, insecure bool) and updated only tlsbridge/upstream_test.go and cmd/authbridge-proxy/main.go. It missed the five call sites here plus one in tunnelreason_integration_test.go. No build tag on these files, so it's a straight compile failure in the forwardproxy test package. main has been red since 69b48de6.

The false values are right — they preserve the pre-#677 verifying behavior at every site, including TestBridge_UnverifiableUpstream_FallsOpenToTunnel, which needs verification enabled for its premise to hold.

Two asks:

  1. Consider cherry-picking ff9e2ed into its own fix: PR so main goes green immediately instead of waiting on review of the parity work. If you'd rather keep it here, that's fine too — but then this PR should be treated as merge-blocking-urgent.
  2. Either way, mention it in the PR body. Right now the description is purely about parity body coverage, so a reader has no idea this PR carries a build fix.
