fix(jobs,core,db): a sleep that never ends, a locale echoed into a log, and a URL that opened a pool on the wrong engine - #379
Conversation
…g, and a URL that opened a pool on the wrong engine Three correctness defects, each in a different tier, each found by a sweep rather than by a report — plus the last live CodeRabbit item from the 17.0.0 cycle. **`jobs` — `step.sleep(NaN)` is a sleep that never ends (#376).** A THIRD duration→ms conversion, unscreened, and the one every scheduling decision goes through. `wakeAt = at + toMs(duration)` is `NaN`, and `NaN` fails every `wakeAt <= now` comparison forever. Ten call sites, not the nine the issue counted: `steps.ts` converts twice for `waitForEvent`. `job.timeout` was the genuinely unguarded one — `stepTimeout` and `eventPoll` already asserted finite-and-positive, `timeout` asserted nothing, so `timeoutMs: NaN` reached `raceTimeout` and the wall-clock limit simply did not exist. Floor is `finiteOption`, decided by grep and not by instinct: `backoffDelayMs({ maxDelay: -5 }, 1) === 0` is asserted under a describe titled "invalid inputs answer core's number", and `retry: { delay: 0 }` appears in seven places across four job suites. `finiteCount` would have refused all of it. Negative, zero and fractional durations still pass; only non-finite is refused. Renamed `toMs` → `finiteDurationMs`, forced by a ratchet: `finite-bounds` detects a repair off the CALLEE'S NAME, so folding the screens inward made four sites read as unscreened. The honest repair was to name the callee for what it does — and a name that is not `toMs` also removes the trap the issue names, where three functions spelled `toMs`, `toMs` and `toDurationMs` defeat any rule spelled by name. Never exported, so nothing outside the package could bind it. **`core` — an Accept-Language value in a 400 body and the log line (#366).** Unbounded and under no key a redactor could name. Bounded to 35 code points (RFC 5646 §4.4.1, read rather than the issue's "~35"), with `meta: { locale }` carrying the whole tag under a name. `describeValue` was refused here on purpose: it renders `'en_US'` as "a 5-character string", deleting the only actionable content in a message whose job is to say which tag was refused. The eight assertions that matched on prose now read `meta.locale` — asserting on prose is why this was eight files instead of one. The log-injection half of #366 was already closed and the issue did not know it: `UltimateError`'s constructor runs `singleLine` over every cause. Deliberately did NOT add a second `singleLine` at the raise site — no mutation can turn it red, and code a test cannot distinguish is what this repo ratchets against. **`db` — a scheme-less DATABASE_URL (#367).** Worse than filed. `Bun.SQL` does not reject `db.internal:5432/app`; it parses host, port and database out of it and OPENS A POOL, so the first symptom is a connect failure at the first query. `sqlite://./dev.db` does not fail even then — it succeeds, on a different engine. Scheme set measured against the driver, not assumed: `postgresql+ssl:` is refused by `Bun.SQL` itself, `mysql:`/`sqlite:`/ `file:` are the dangerous half. The received scheme is NOT echoed back. For exactly the values this screens, `new URL(…).protocol` is not a scheme: `db.internal:5432/app` yields `'db.internal:'`, the host, and `app:hunter2@db.internal:5432/app` yields `'app:'`, the username. Naming the REQUIRED schemes is the whole executable content and carries no credential. **`time` — the refusal named a function the caller never typed.** Same review finding one tier down, surfaced by the jobs work. `toMs`/`toSeconds` take an optional subject and option so a refusal names `clock.advance`, not `toMs`. Optional, so no caller's arity changes and today's message is reproduced byte for byte — which is correct, because a direct `toMs` caller DID write `toMs`. Only callers reached through it were misled, and `fixture-clock.ts` was the only one in the tree. **CodeRabbit, last open item.** `packages/db/src/client.ts` 263 → 177 LOC. The extracted seam is the statement funnel, not ambient-client access — measured: ambient is 28 lines and leaves the file at 235, still over. The funnel closed over none of `createPostgresClient`'s state, so the move invented no signature and changed no consumer import. Zero test assertions edited. Every fix is mutation-verified: the screen deleted, the caller name dropped, the scheme check widened, the excerpt uncapped — each turns the discriminating test red and nothing else. One weak assertion was found and strengthened this way: `toContain('delay')` passes against an unrelated internal refusal naming `backoffDelay`, because it is a substring.

Provide one executable JSON-capable fix command.
This error tells the user to run x dev, but the command has no --json mode in the fix text. Invalid DATABASE_URL values fail at boot, so agents cannot apply this remediation through the required machine-readable command path. Replace the prose alternatives with a verified executable command that includes --json.
As per path instructions, error fixes must be executable commands. As per coding guidelines, every CLI command and error must support --json.

Keep the documented constraint consistent with job().
packages/jobs/src/job.ts accepts finite fractional stepTimeout and eventPoll values because it checks Number.isFinite(value) && value > 0. It does not require a whole number. Replace “positive whole number” with “finite positive number,” unless integer validation is intended.
As per path instructions, preserve meaningful fractional semantics where the API supports them.

Use testName(type, name) for this test.
packages/testing requires every test title to use testName(type, name). The literal title bypasses the naming contract that x verify uses for filtering.
As per coding guidelines, “Always name tests through testName(type, name) so x verify can filter them.”

…uld not fail CodeRabbit round on #379. Three of six findings fixed, three declined with the convention that contradicts them (full reasoning in the PR thread). **The colocated funnel test was the valuable one.** It closes a gap the implementing agent had independently flagged: `affectedBy`'s return-value contract was pinned by exactly one observer assertion, and the pooled `execute()` row count only by `client.live.test.ts`, which skips without `TEST_DATABASE_URL`. Writing it found **a test of mine that could not fail.** The first version of "an observer that throws on success is not reported as failed" asserted only that the throw escapes — which it does whether the success event sits inside or outside the `try`. Moving the event inside left it green. The discriminating assertion is the event LEDGER, not the throw: under that mutation the catch emits a second event carrying `error`, so `toHaveLength(1)` plus `error` being undefined is what actually pins the placement. Red under it now. Four mutations, each red on the right test: drop the error-path event (1 fail), `affectedBy` → 0 (3), move the success event inside the try (1), don't type the driver error (2). **`outbox.ts` — `Date.now()` out of the doc example.** A regression this PR introduced: the original said `nowMs()`, which was wrong because an app author cannot import it, and the repair reached for `Date.now()`, which `packages/core/src/clock.ts:2` forbids in as many words — "Nothing else may call `Date.now()`." Now the caller's own clock. **`duration-bounds.test.ts` — caught errors narrowed, not cast.** The helpers double-cast `unknown` through a record to `string`, which reports a FOREIGN error's missing field as `undefined` and fails the assertion on the wrong thing. `instanceof UltimateError` with a rethrow for anything else. Two ratchet blind spots found on the way, both deferred to the #365 ratchet PR rather than widened here: - `scripts/test-bare-error.ts` exempts the forbidden shape inside a STRING literal but not inside a COMMENT, so a comment quoting it in order to explain it counts as committing it. `dead-docs-host` already carries exactly this exemption. - `scripts/finite-bounds.ts` recognises a screen by whether the CALLEE'S NAME contains `Finite` — the same name-spelled trap that made a rule spelled `RenderMode` read past `PwaRenderMode`. That is what forced the `toMs` → `finiteDurationMs` rename in this PR. `packages/jobs/src/outbox.ts` is at exactly 500 lines, the hard ceiling — the two-line comment this round added is what tripped `filesize`, and the next line anyone adds trips it again. Flagged, not split: a real split is its own change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
