Finishes quest/m1/mock-clock-tests/js-net.md, a child of the mocked-clock epic.

Summary

js/net tests no longer show that nothing happened by waiting on the host clock, sleep to let things settle, or assert on elapsed real time. Each one now runs on a Manual clock or awaits the event it is testing. Every bare hostTime(); opt-out in js/net is gone, so the bun test guard now covers these tests. The only opt-out left is connect.test.ts's hostTime(); // a real HTTP server, which does real I/O.

  • Shared helpers in src/mock.ts:
    • manual() installs a Manual clock until the test's scope ends.
    • settlesWithin(work, clock, window) replaces each real-time negative-proof window with mocked time of the same length.
    • driveUntil(clock, work) moves the clock forward 1 ms at a time, with a host turn before each step.
  • Helpers that resolved undefined on a timeout now await the event: nextUni/nextStream (ietf/publisher, ietf/subscriber, ietf/join) and servedGroup (lite/publisher). The if (!x) throw guards after their callers are removed. closeCode (ietf/malformed) now advances its 50 ms window on the mocked clock instead of racing Bun.sleep(50).
  • Waits on a production timer are now driven, not slept through. This covers the 1 s datagram end grace (ietf/datagram, lite/datagram-tracks), SETUP's close grace (connect), reload backoff (reload), and the PUBLISH_NAMESPACE retry (ietf/goaway).
  • Elapsed-time assertions now measure mocked time (tail, ietf/tail). I checked that a Stream Count mismatch fails the ietf/tail assertion right away (Received: 1000), where before it would have waited out the real grace.

The js/net suite (127 files) took 43.6 s on the parent commit and now takes 6.0 s. Some files:

File Before After
lite/datagram-tracks 10.2 s 0.27 s
ietf/datagram 10.2 s 0.12 s
lite/publisher 6.1 s 0.23 s
integration 3.3 s 0.88 s
ietf/goaway 1.06 s 0.06 s
ietf/malformed 0.54 s 0.09 s

Choices made without asking

  • driveUntil instead of Manual.drive where work waits on a host task the clock can't see. drive drains once and then fires the earliest deadline. In connect.test.ts, the client needs a second host turn to read the server's SETUP, so drive fired the 30 s connect timeout first. The IETF handshake's dynamic import() does the same in reload. driveUntil gives the host a turn before each 1 ms step. Its cap is 10 mocked seconds, so it can drive past the 1 s grace. Where drive was safe (ietf/datagram, lite/tail, ietf/goaway, lite/publisher, integration), I kept it, since it stops exactly at the deadline.
  • The track.test.ts livelock test delivers its next group in yieldNow() instead of a 10 ms sleep. A host task still can't run if the reader livelocks on microtasks, and no timer is armed.
  • Watchdog races in positive helpers became plain awaits. A regression now fails at bun's per-test timeout. The epic allows progress-only waits.
  • Left alone:
    • bandwidth.test.ts's and migrate.test.ts's waitUntil. They poll for progress without arming a timer.
    • connect.test.ts's until, which polls a real socket.
    • The files that already install a Manual by hand with try/finally.
    • Sibling tests in other languages. The quest lists only js/net, and the Rust relay's are rs-relay.md.

moq-dev/moq#8157 also edits lite/datagram-tracks.test.ts, adding a test and imports. Whichever PR lands second will likely hit a small conflict in the import block.

Public API: none. Wire: none. src/mock.ts is test support and not exported from the package. Its additions are new exports only, so the js/crypto tests that import it still pass.

Validation

  • bun test in js/net: 3128 pass, 0 fail (8.2 s) after merging origin/main (9920a3f550). The only conflict was the lite/publisher.test.ts import block, where main added staleHole. Main's new tests add no hostTime(); opt-outs or real sleeps.
  • Under load: three parallel bun test --rerun-each 5 runs over the 18 changed files other than connect.test.ts gave 6025 pass and 0 fail each. Five connect.test.ts runs alongside them passed.
  • git grep -n "hostTime();$" -- js/net finds nothing.
  • bun biome check --error-on-warnings js/net passes, and so does bun run check in js/net (tsc for the package, examples, and bench).
  • The js/crypto tests that import mock.ts pass.
  • quest check --base origin/main passes.

mechanical fix by quest land watch: merged main at 893e676c64d725eb84144afbaa7fc17141d97370 with the quest merge driver (head 7165360)

Codex (gpt-6.1-sol, medium effort) reviewed head 378a003b6052e0b8f0553f90456a4621cfa0508f against origin/main (9920a3f550) with quest review (round 2, after the merge with main). It reported no findings.

Follow-ups

  • Pre-existing flake: integration: lite-07 reports a relative start over a frameless newest group failed once in a baseline run (start() was 0n, expected 5n). No open quest or PR covers it.
  • The connect.test.ts WebSocket-preference tests fail under bun test --rerun-each, on main too. The module-level preference cache carries over between reruns. A plain run passes.
  • Manual.drive can fire a far deadline while its work waits on a host task the clock doesn't count. Examples are a host stream read or a dynamic import(). driveUntil works around this in tests. A fix in the clock would let those tests use drive and stop exactly at the deadline.

Negative proofs, settle sleeps, and elapsed-time assertions across js/net
now run on a Manual clock or await the event they mean, and every bare
hostTime() opt-out is gone, so the bun test guard covers them.

- mock.ts gains manual(), settlesWithin(), and driveUntil(), shared by
  every converted file; the helpers that resolved undefined on a timeout
  (nextUni, nextStream, closeCode) now await the event or advance the
  mocked clock past their window.
- Tests that wait out a production timer (the 1s datagram grace, SETUP's
  close grace, reload backoff, PUBLISH_NAMESPACE retry) drive the clock
  instead of sleeping on the host.

Walkthrough

The JS network test suite replaces host-time sleeps and polling with manual-clock control and event-based waits. Shared helpers install clocks, check promise settlement, and advance time until a condition is met. Test stream helpers in IETF and Lite cases now wait for streams or session termination rather than using timeout-based optional results. The mocked-clock test plan and its README entry are removed.

Merge Risk: Low · up to 785f8

The clock migration has a small remaining coverage gap: the announcement shutdown test can pass when drain rejects. Merge risk is low; awaiting the drain promise would restore the success check.

Automated review by review (OpenAI)

Reviewed head 441fbec.

No actionable findings in the test-clock conversion. Moving negative assertions to explicit simulated windows, awaiting positive events directly, and retaining host turns for stream/handshake progress is a sound direction. The elapsed-time assertions still distinguish immediate completion from grace expiry, and the scoped manual clock restores the prior clock on exit.

Verification: GitHub-only static review of the changed tests/helpers and Manual clock/drain implementation. I did not run Bun, type checking, load tests, or reproduce the reported speedup; runtime scheduling and flake claims remain unverified.

  • Shared clock helpers in mock.ts: manual() installs a Manual clock until disposed, settlesWithin(work, clock, duration) advances a mocked window and reports whether the work settled, and driveUntil(clock, until) steps 1 ms at a time with a host turn between steps for work the clock cannot see.
  • Negative proofs moved to mocked windows: auth, ietf/datagram, ietf/goaway, ietf/request_stream, ietf/subscriber, lite/connection, lite/publisher, lite/tail, lite/track_stream, and integration replace sleep/Promise.race windows with settlesWithin on the manual clock.
  • Positive helpers await the event: nextUni/nextStream (ietf/publisher, ietf/subscriber, ietf/join) and servedGroup (lite/publisher) no longer resolve undefined on a timeout; absence is asserted with opens/noStream/opensGroup.
  • Production timers are driven: the datagram end grace, SETUP close grace, reload backoff, PUBLISH_NAMESPACE retry, and probe interval are advanced with clock.drive/driveUntil instead of real sleeps.
  • Elapsed-time assertions measure mocked time: tail and ietf/tail compare clock.now() deltas.
  • Quest cleanup: quest/m1/mock-clock-tests/js-net.md is deleted and its ## Required line removed from the epic README.

I checked the remaining hostTime() opt-out (connect.test.ts:231, a real HTTP server), the reload.test.ts waitUntil that still polls the host clock without arming a timer, the connect.test.ts until helper that is only reached by the hostTime() test, and the quest deletion for leftover references. All are consistent with the PR's claims.

Check completion without advancing mocked time.

A 990 ms delay can pass the current assertion. Await the read with the clock paused to check that meeting the stream count completes without a timer.

quest land watch: armed auto-merge on this pull request at 46ff145, so it joins the back of the merge queue once its required checks pass, with the land fixer's fix (codex, gpt-6.1-sol, medium effort): Merged base and removed the stale prerequisite link to the completed js-net quest; ran bash sh/quest.sh check, just ci base, and git diff --check..

3216-3216: Trivial · Maintainability & Code Quality · Low value

Assert that the drain fulfills.

If drain() rejects independently after withdrawal starts, settlesWithin returns true and running can still succeed. Await the drain promise after checking its timing.

Suggested fix

-	expect(await settlesWithin(publisher.drain(), clock)).toBe(true);
+	const drained = publisher.drain();
+	expect(await settlesWithin(drained, clock)).toBe(true);
+	await drained;

js/net/src/lite/datagram-tracks.test.ts: 1

64-67: Trivial · Functional Correctness · Low value

Test late datagram delivery during legacy tail grace.

The lite-05/06 datagram-only case has an uncovered tail, but it receives its only datagram before finish. driveUntil also accepts an early end. Add a test that delays a datagram until SUBSCRIBE_FINISH arrives and checks its payload before advancing through the grace.

Review comment at @js/net/src/lite/datagram-tracks.test.ts around lines 64 - 67:
The datagram-only test does not cover delivery during the legacy tail grace.
Update the lite-05/06 test using `driveUntil` so it waits for
`SUBSCRIBE_FINISH`, then delivers a delayed datagram and asserts its payload
before advancing the clock through the grace; do not treat an early end as
sufficient.

quest land watch: the merge queue removed this pull request at 46ff145 because it conflicts with main (merge_conflict).

The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.
