There was a problem hiding this comment.
No bugs found, and my earlier nit (stale no-validate-leaksan.txt entry) is addressed. Deferring to a human for final sign-off because this bundles a few judgment calls beyond mechanical pruning: deleting six vendored Node tests outright (vs. leaving them quarantined for a future internal/js_stream_socket / libuv-_handle compat effort), un-quarantining two FLAKY entries on the strength of three green builds, and loosening the ASAN leak-fixture threshold 400→500 MB.
What was reviewed:
- Confirmed every deleted test file has no remaining reference in any
test/*.txtsuppression list. - Checked the
describe.skipIf(isASAN)scope ininspect.test.ts— only the websocket suite is gated; http-metadata / unix-socket / error.stack still run. - Verified the non-ASAN leak threshold in
esm-fixture-leak-small.mjsis unchanged at 100 MB.
Extended reasoning...
Overview
Test-infrastructure-only PR that empirically re-derives test/expectations.txt by removing all 29 entries, running the full CI matrix (build 87834 + confirmation builds 87845/87860), and keeping only the 6 that still fail on their named lane. Six vendored Node tests that can never pass as written (missing internal/js_stream_socket, libuv-seconds _handle.setKeepAlive, un-vendored spawned helper) are deleted rather than re-quarantined. Six ASAN quarantines are downgraded to no-validate-exceptions.txt so the test bodies now run with validateExceptionChecks off. inspect.test.ts gets a suite-scoped describe.skipIf(isASAN) in place of a whole-file quarantine. The ASAN branch of esm-fixture-leak-small.mjs moves 400→500 MB after build 87834 measured 407 MB.
Security risks
None. No production code is touched — only test files, quarantine lists, and a leak-fixture threshold.
Level of scrutiny
Medium. The blast radius is CI stability, not shipped behavior: if any un-quarantined test is still flaky it turns lanes red and is trivially reverted. What warrants a human eye is the policy content: (1) deleting vendored Node tests forecloses them being rediscovered when/if the underlying compat gap is closed — REVIEW.md does say "delete dead code" and each has a stated reason, but a maintainer should confirm these six are genuinely never-going-to-pass rather than tracking a planned feature; (2) test-tls-connect-memleak.js and fetch-abort-slow-connect.test.ts were quarantined as FLAKY with detailed timing-race explanations, and three green builds is thin evidence that the underlying race is gone rather than dormant; (3) the 400→500 MB ASAN bump is justified by a single 407 MB observation — the non-ASAN 100 MB bound (the real signal) is untouched, so this is low-risk, but it is still weakening a safety net per REVIEW.md.
Other factors
The methodology is sound and well-documented with per-entry build evidence. Jarred already engaged (requested the spawn.test.ts ASAN un-skip after #36783 landed, which was done). Both prior review comments (CodeRabbit's whole-file inspect quarantine, my stale leaksan entry) were addressed and resolved. The net effect on coverage is strictly positive — more tests run on more lanes than before. I'm deferring only because "delete these six tests permanently" and "un-flake based on N=3" are maintainer calls, not because anything looks wrong.
There was a problem hiding this comment.
My earlier note about the stale no-validate-leaksan.txt entry was addressed in 7e9eedf, and I didn't find anything new in the two commits since. Deferring to a human for the final call on permanently deleting the 6 vendored Node tests and un-quarantining the 10 previously-flaky/failing entries — those are maintainer-level judgment calls, and the confirmation build (#87868) on the latest commit is still the source of truth for whether the un-quarantined tests hold up across the full matrix.
What was reviewed:
- Verified all 6 deleted test files have no remaining references in
test/*.txtsuppression lists. - Checked the
describe.skipIf(isASAN)ininspect.test.tsscopes only the websocket suite; http-metadata / unix-socket / error.stack tests still run on ASAN. - Confirmed the
esm-fixture-leak-small.mjsbump (400→500 MB) is ASAN-only; the load-bearing non-ASAN 100 MB threshold is unchanged.
Extended reasoning...
Overview
This PR empirically re-derives test/expectations.txt by removing all 29 quarantine entries, running the full CI matrix (build 87834), and keeping only the 6 that still fail. It also deletes 6 vendored Node tests that can never pass (require internal/js_stream_socket, spawn a non-vendored helper, or assert libuv-internal _handle semantics), moves 6 tests from full-file quarantine to no-validate-exceptions.txt so they actually run on ASAN, replaces one whole-file ASAN quarantine with a targeted describe.skipIf(isASAN), bumps one ASAN leak-fixture threshold, and drops a stale no-validate-leaksan.txt line. Net effect is +42/-385 across 11 files, all under test/, and strictly increases the number of tests that execute.
Security risks
None. No production code is touched; the changes only affect which test files run on which CI lanes and under which sanitizer flags.
Level of scrutiny
Moderate. It's test-infrastructure only with zero user-facing blast radius, but it embeds several judgment calls: (a) deleting vendored upstream Node tests rather than leaving them quarantined as future-work markers, (b) un-quarantining two previously-FLAKY entries based on three probe builds, and (c) widening an ASAN leak threshold from 400→500 MB after a 407 MB observation. Each is individually reasonable and well-argued in the description, but collectively they're the kind of CI-policy decisions a maintainer should sign off on. Jarred has already engaged with the PR and requested one change (spawn.test.ts un-skip after #36783), which was made.
Other factors
All prior review feedback (CodeRabbit's inspect.test.ts scoping, my stale leaksan entry) is addressed and marked resolved. The deleted keepalive tests cite test/js/bun/net/socket.test.ts as replacement end-to-end coverage, satisfying REVIEW.md's "every deletion needs a stated reason or replacement." The final CI build (#87868) on commit d0fe300 is what actually validates the un-quarantines across the full matrix — I can't verify its result from here, and any of the 10 un-quarantined tests turning red there would change the picture. Given the scope and the pending full-matrix result, deferring rather than approving.

@robobun the list of expectations is stale now, rebase |

@robobun and remove that ASAN gating if you can? |
…re still needed Every entry removed. CI on this commit will show which quarantined files actually still fail, crash, leak, or time out on the lane their modifier named. Entries that come back green on every matching lane were stale and will stay deleted; entries that go red get re-added with a fresh comment naming the observed failure.
These require internal/js_stream_socket (the libuv js_stream wrap), which Bun does not implement and has no plans to. They have been quarantined since they were vendored and have never run.
… lane test-net-connect-keepalive.js and test-net-server-keepalive.js assert _handle.setKeepAlive receives seconds (libuv convention); Bun's _handle is the public Bun.Socket whose setKeepAlive is documented in milliseconds, so this can never pass. End-to-end TCP_KEEPIDLE coverage lives in test/js/bun/net/socket.test.ts. test-set-http-max-http-headers.js spawns test-http-max-http-headers.js, which is not vendored, so the spawned child exits 1 with Module not found and the two 'expecting success' subtests assert code===0.
…tests to no-validate-exceptions.txt
Of the 29 entries removed in the probe commit, build 87834 showed:
Kept (7): native-plugin.test.ts [WINDOWS], inspect.test.ts [ASAN],
test-net-pingpong.js / test-net-pipe-connect-errors.js /
test-net-client-bind-twice.js / test-net-server-reset.js [WINDOWS],
test-net-listen-shared-ports.js [LINUX]. All still fail on the named
lane with the same error mode.
Moved to no-validate-exceptions.txt (6): the four next-pages / next-auth
tests (JSOrderedHashTable getImpl -> executeBoundCall), napi.test.ts
(Process_functionDlopen), require-cache.test.ts (NapiClass
finishCreation). These now run on ASAN with validateExceptionChecks off
instead of being removed entirely.
In-file skipIf(isASAN) (2 subtests in spawn.test.ts): the two
'leaves a ... stdout fd open when stdin stream setup fails' tests hit a
heap-use-after-free on release-asan. The other 135 tests in the file now
run on ASAN; previously the whole file was removed.
esm-fixture-leak-small.mjs ASAN threshold 400 -> 500: build 87834
measured 407 MB under ASAN quarantine.
Removed (9, now pass on their named lane): test-repl-close.js
[WINDOWS-AARCH64], test-tls-connect-memleak.js [LINUX-X64-MUSL],
spawn-maxbuf.test.ts, tls-sql.test.ts [ASAN], pathToFileURL.test.ts
[ASAN], abort-signal-leak-read-write-file.test.ts [ASAN],
streams-leak.test.ts [ASAN], test-net-server-listen-path.js [WINDOWS],
fetch-abort-slow-connect.test.ts [DARWIN].
Deleted files (6, previous commits): test-stream-wrap*.js (3),
test-net-{connect,server}-keepalive.js, test-set-http-max-http-headers.js.
Rebased onto main which now has #36783 (sink: detach JSSink controller when assignToStream throws) fixing the heap-use-after-free, so the two 'leaves a ... stdout fd open' tests no longer need skipIf(isASAN). spawn.test.ts reverts to main's version; all 145 tests now run on ASAN.
…le quarantine
The websocket describe's first test ("bun --inspect") hangs reading
stderr for the listening URL on release-asan and exhausts the file's
270s budget. The http-metadata, unix-socket and error.stack tests pass
on ASAN (verified under bun bd: 7 pass, 23 skip, 0 fail), so skip only
the websocket describe instead of removing the whole file.
expectations.txt is now down to 6 entries.
…ttp-max-http-headers.js
The inspectee child's Runtime.evaluate path trips an unchecked getOwnNonIndexPropertyNames -> JSObjectInlines::get scope under validateExceptionChecks (build 87863), aborting the child and leaving the unix-socket tests hanging for the parent's connect. With validateExceptionChecks off the http-metadata, unix-socket and error.stack tests pass on ASAN (7 pass / 23 skip / 0 fail).
…t.test.ts without the websocket ASAN skip #36786 fixed test-net-pipe-connect-errors.js, test-net-client-bind-twice.js and test-net-server-reset.js on Windows by mapping the WSA error to the SystemErrno discriminant. test-net-pingpong.js remains (separate uv_shutdown gap). inspect.test.ts: the no-validate-exceptions.txt entry on its own may be enough on release-asan now that validateExceptionChecks is off; the earlier 270s hang on the first websocket case was with that flag set. Letting CI decide; will restore the describe.skipIf(isASAN) if it still hangs. expectations.txt is now 3 entries.

No issues found — both earlier notes (stale leaksan entry, stale inspect comment / leaksan trim) are addressed in 64f2f1b. Deferring to a human sign-off since this un-quarantines ~20 files (including two previously-FLAKY entries) and deletes 6 vendored Node tests; worth confirming build #87941 is fully green across the matrix before merge.
What was reviewed:
- Verified none of the 6 deleted test paths remain referenced in any
test/*.txtsuppression list. - Confirmed the keepalive coverage claim:
test/js/bun/net/socket.test.ts:1853-1926exercises TCP_KEEPIDLE end-to-end for both Bun.connect and node:net. skipsForLeaksannow.trim()s lines, matchingskipsForExceptionValidation— no other un-trimmed suppression parsers inrunner.node.mjs.- ASAN leak-fixture bump (400→500 MB) is against a measured 407 MB; release threshold unchanged at 100 MB.
Extended reasoning...
Overview
This PR is test-infrastructure only: it prunes test/expectations.txt from 29 entries to 3 (empirically re-derived via full-matrix probe build 87834 + confirmation builds 87845/87860/87868/87938), deletes 6 vendored Node parallel tests that can never pass as vendored (missing internal/js_stream_socket, libuv-seconds _handle.setKeepAlive convention, un-vendored spawn target), moves 7 files from full-removal to no-validate-exceptions.txt so they now run on ASAN with validateExceptionChecks off, bumps the ASAN threshold in esm-fixture-leak-small.mjs from 400→500 MB, drops one stale line and one trailing space from no-validate-leaksan.txt, and adds .map(line => line.trim()) to the leaksan suppression parser in scripts/runner.node.mjs. No runtime/native code is touched.
Security risks
None. All changes are to CI test-gating configuration, suppression lists, a leak-test threshold constant, and deletion of vendored upstream test fixtures. Nothing user-facing, no auth/crypto/permissions.
Level of scrutiny
Medium. The change is mechanically simple but broad in effect: removing quarantines re-enables ~20 files across the CI matrix, and deleting vendored Node tests is a policy decision. The correctness proof for the un-quarantines is "CI is green on the probe builds" — which is exactly what the PR description documents with build numbers per lane — but two of the removed entries were FLAKY (test-tls-connect-memleak.js on musl, fetch-abort-slow-connect.test.ts on darwin), and 3-4 green runs is a small sample for de-flaking. The final commit's build (#87941) was still running per the timeline; a maintainer should confirm it's fully green before merge.
Other factors
- Jarred has been actively directing this PR (requested the spawn.test.ts un-skip, the rebase, and the ASAN-gating removal), so human review is already in the loop.
- Both of my prior inline findings and both CodeRabbit findings were addressed in follow-up commits with build-number verification; all four threads are resolved.
- The 7 files moved to
no-validate-exceptions.txtare a net coverage increase on ASAN (they now run instead of being removed entirely); each entry has a specific unchecked-scope citation. - Verified the keepalive-deletion rationale:
test/js/bun/net/socket.test.tshas getsockopt-level TCP_KEEPIDLE coverage for both Bun.connect and node:net, so end-to-end behavior remains covered even though the libuv-convention_handlemock tests are removed. - The
scripts/runner.node.mjschange is a one-line.trim()that brings the leaksan parser to parity with the exceptions parser directly above it; both use identical.includes()matching, so no behavior change beyond tolerating whitespace.
There was a problem hiding this comment.
LGTM — all prior review feedback addressed; test-infra cleanup that net-increases coverage.
What was reviewed:
- Verified the 6 deleted vendored Node tests have no remaining references in any
test/*.txtsuppression list. - Confirmed

Extended reasoning...
Overview
This PR is test-infrastructure maintenance: it empirically re-derives test/expectations.txt (29 → 3 entries) against multiple full CI runs, deletes 6 vendored Node tests that require unimplemented Node internals (internal/js_stream_socket, an un-vendored helper, or libuv-seconds _handle.setKeepAlive), moves 7 tests from full ASAN quarantine to no-validate-exceptions.txt so they now run on ASAN with validateExceptionChecks off, bumps one ASAN-only leak-fixture threshold, and adds .trim() to the leaksan suppression parser. No runtime code is touched.
Security risks
None. Changes are confined to CI test-runner config, suppression lists, a leak-fixture threshold constant, and deletion of already-quarantined vendored tests. Nothing user-facing, no auth/crypto/permissions.
Level of scrutiny
Low-to-medium. The risk profile is inverted from typical: this PR removes skips, so any error surfaces immediately as CI red rather than hiding as lost coverage. The PR description cites specific BuildKite builds (87834 probe; 87845/87860/87868 confirmations; 87938 for the inspect ASAN result) for each claim, and Jarred has been actively directing the changes throughout the thread.
Other factors
All three of my earlier inline findings (stale leaksan entry for the deleted test-set-http-max-http-headers.js, trailing-space entry that never matched, stale skipIf(isASAN) comment) and both CodeRabbit findings have been addressed and marked resolved. The one net reduction in stated coverage — deleting the 6 vendored Node tests — is well-justified per REVIEW.md's "delete dead code in the same PR that makes it dead": each was permanently [ FAIL ]-quarantined and depends on Node internals Bun doesn't implement, with the equivalent end-to-end coverage (e.g. TCP_KEEPIDLE) named in the PR body. The 400→500 MB ASAN threshold bump is scoped to the ASAN branch only and cites the measured 407 MB from build 87834.
