test(#349): external / tick / negative の待ちを pollUntil / tickUntil / Collector / 番兵に移行する - #352
Conversation
step 3–4 の共有 primitive。pollUntil は読むしかない状態(subprocess が書くファイル、 kill(pid, 0)、OS の reap)専用の期限付き poll で、Bool を返し呼び出し側が assert する。 tickUntil はテスト自身が tick して進める subject を tick 回数で有界に待つ(壁時計なし、 @mainactor)。false は否定検査(n tick 回して起きない)の形にもなる。両者とも cancellation で即 false を返す (.timeLimit がテストを cancel したとき自分の上限まで空回りしない)。 TestSupportTests に両者の契約(即時 / 成立で返る / 期限・budget 切れを報告 / cancellation で終わる) を追加。 Part of #349
…ollector / 番兵に移行する #349 の残り 3 クラス(external 43 / tick 駆動 13 / negative 13)を、待ちの根拠が名前と形から分かる形に置き換える。 - external: DispatchSource / FSEvents の callback(ConfigWatchTests, FileWatchGatewayTests)は テストが持つ spy なので Counter / FiredBox を Collector<Void> に置換して待つ。rename 後の quiescence(イベント数が不定)だけ pollUntil に残す。subprocess の状態(DarwinGatewayTests)は 読むしかないので、同期 helper(waitUntilRunning / waitForLockFile / waitForFile)と usleep ループを `try #require(await pollUntil(timeout: .seconds(30)) { … })` に集約する。 - tick 駆動: SpectrumPresenterTests / SpectrumViewRenderingTests の private tickUntil / tickUntilBars と Lyrics の updateActiveLineTick ループを共有 tickUntil に寄せ、frames-to-clear の計測を wall clock ではなく tick 予算で有界にする。否定窓は `tickUntil(100, …) == false`。 - negative: stop() 後の不変は handleEvents(receiveCancel:) → Collector<Void> で購読解除そのものを待つ (AppPresenter / ConfigStatus / Header / Lyrics)。重複 update の非再トリガーは同一 pipeline に番兵を 流して settle し、その間の遷移記録に再トリガーが無いことを assert する(Header / Lyrics duplicate)。 WallpaperPresenterTests の 1 item ループは AVPlayer.rate の KVO を Collector に記録して loopCurrent() の play() を待つ。 - Tests/PresentersTests/TestSupport/WaitUntil.swift を削除。 全体実行で見つかった hang も同じ規則で直す: テストを async 化したことで `await pollUntil` の後に 別の協調スレッドで再開し、`Process.waitUntilExit()`(呼び出しスレッドの run loop を回す)が 起動スレッド側に配られる終了通知を受け取れず永久待機していた(reacquireAfterCleanup、子は回収済み、 time limit も届かない)。DarwinGatewayTests/LaunchedProcess.swift で terminationHandler を Collector に 記録し `waitForExit()` で待つ。pollUntil / tickUntil 自体も cancellation で即 false を返すようにし、 契約テストを足す。 docs/ARCHITECTURE.md に step 3–4 の Key Design Decision を追加、CLAUDE.md / AGENTS.md の Testing Guidelines を同期。

- Line 57: Update the testing guidance in .claude/CLAUDE.md:57 and AGENTS.md:208
to distinguish cancellation from tick-budget exhaustion when interpreting
tickUntil(_:tick:until:) returning false. Require callers to verify the task was
not cancelled before treating false as proof that no event occurred, or revise
the helper contract/documentation to make that negative assertion unambiguous;
apply the same wording and behavior in both duplicated rules.
In `@Tests/ConfigDataSourceTests/ConfigWatchTests.swift`:
- Line 470: Update the rename-handling test around pollUntil and the settled
callback count so it waits for an explicit post-rename edit observation or
re-arm state, rather than stopping at the first callback after afterRename;
ensure the final assertion proves the in-place edit on the new inode was
received.
In `@Tests/DarwinGatewayTests/ProcessLockTests.swift`:
- Line 146: In ProcessLockTests, add a process-group cleanup defer immediately
after assigning pid from holder.processIdentifier, so cleanup runs even when
either following `#require` throws. Ensure the defer terminates the holder’s child
process group on every exit path while preserving the existing normal cleanup
behavior.
In `@Tests/TestSupport/PollUntil.swift`:
- Line 23: Update pollUntil so it checks task cancellation before evaluating
condition(), ensuring a pre-cancelled call returns false even when the condition
is already true; add a test covering that pre-cancelled, already-true case.

Wait for the sentinel update rather than the existing phase
When subject.send(sentinelUpdate) is queued through HeaderPresenter's .receive(on: DispatchQueue.main), both phase properties are already .revealed, so these settle calls can return from their initial values before the sentinel is processed. The following display and transition assertions can therefore run against the previous track and fail intermittently; await the sentinel-specific display value or the collectors reaching the expected transition count instead.

Avoid timing the immediate-return contract with wall time
On a heavily loaded CI runner, the test task can be descheduled between the two ContinuousClock.now reads for more than one second even though pollUntil evaluates the true condition and returns without sleeping, producing the kind of load-dependent failure these helpers are intended to eliminate. This bound also would not detect an erroneous short sleep; pass a deliberately long interval and verify that the call completes, or test sleep behavior with a controllable clock instead.

Await the rename callback through the collector
When the atomic-save callback is delayed beyond pollUntil's three-second deadline, this discarded false result lets the test append to the new inode before the watcher has re-armed; the late rename callback can then increment onChange and satisfy the final collector wait, falsely attributing that callback to the in-place edit. Since onChange is an in-process DispatchSource callback already recorded by Collector, await its count predicate directly rather than polling it, and do not discard a bounded wait result.

Codex / CodeRabbit の指摘 7 件に対応: - HeaderPresenterDuplicateTests: 番兵送信後の settle が既に .revealed の phase で即時に返り、 前のトラックに対して assert し得た → displayTitle / displayArtist の番兵値で待ってから phase の .revealed を待つ(番兵の text は phase が .revealing になった後にしか書かれない) - ConfigWatchTests: rename 後の pollUntil(結果を捨てていた)を Collector 待ちに。atomic save の churn はラベル無しで最大 3 callback なので、新 inode への in-place 追記を 4 回 await して churn だけでは届かない回数で証明する - pollUntil / tickUntil: cancellation を condition より先に見る(pre-cancelled で true を返さない)。 契約テストを追加し、tickUntil の cancel テストは ticks == 0 を assert - PollAndTickTests: 即時返却の契約を壁時計で測らず、suite の time limit より長い interval で検証 - ProcessLockTests.childDoesNotInheritLock: process group の kill を #require の前に defer - CLAUDE.md / AGENTS.md / TickUntil.swift: cancellation 由来の false が偽陽性にならない理由 (time limit が既に失敗を記録している)を明記 - docs/ARCHITECTURE.md: rename テストの記述と mutation の数値を更新 (poll+tick 556 中 23、4 primitive 551 中 87、全体 1449 tests)

概要
Issue #349 の棚卸しで残っていた 3 クラス —
external43 / tick 駆動 13 /negative13 — は publisher を await できない待ちで、それぞれに別の答えが要る。Tests/TestSupportに有界の待ちを 2 つ足し(どちらもBoolを返し、呼び出し側が assert する)、「起きないこと」は その不在を保証する機構 を待つ形にした。本番コード(Sources/)は触っていない。pollUntil(timeout:interval:_:)kill(pid, 0)、OS の reap。in-process に書き手も callback も無いtry #require(await pollUntil(timeout: .seconds(30)) { … })。期限は失敗側の安全弁で、成功側の遅延ではないtickUntil(_:tick:until:)tick()/updateActiveLineTick()を呼ぶ#expect(await tickUntil(tick: presenter.tick) { … })。上限は tick 予算で壁時計ではない。tickUntil(100, …) == falseが「n tick 何も起きない」の証明LaunchedProcess(DarwinGatewayTests)terminationHandlerをCollector<Void>に記録しawait waitForExit()。terminate()は signal のみどちらも cancellation で即
falseを返す(.timeLimitがテストを cancel したとき、自分の上限まで空回りしない)。契約はTestSupportTests/PollAndTickTestsの 8 テストで固定(cancellation は条件より先に見る)。分類ごとの置き換え
external— 待つ対象で再分類DispatchSource/ FSEvents(ConfigWatchTests、FileWatchGatewayTests): 棚卸しでは「原因が OS」なので external に数えていたが、signal は gateway の callback — テストが持つ spy — なのでCounter/FiredBoxをCollector<Void>に置換しwaitForCount(1)/settle { $0.count > n }で待つ。rename 後の待ちも poll ではなく Collector 待ち: atomic save は最大 3 回のラベル無し callback(directory watch の temp 作成 + rename、旧 inode の rename)を出すので、新 inode への in-place 追記を 4 回 await して churn だけでは届かない回数を積む(レビュー対応)。DarwinGatewayProcessTests、DarwinGatewayRunProcessTests、ProcessLockTests): external そのもの。同期 helper(waitUntilRunning/waitForLockFile/waitForFile)とusleepループを 13 箇所のtry #require(await pollUntil(timeout: .seconds(30)) { … })に集約。自分の cancel を観測するまでのTask.yield()スピンは、cancel で抜ける 30 秒Task.sleepに。tick 駆動
SpectrumPresenterTests/SpectrumViewRenderingTestsの file-privatetickUntil/tickUntilBarsと、Lyrics のupdateActiveLineTick()ループを共有tickUntilに寄せた(26 箇所)。frames-to-clear の計測は壁時計の期限ではなく tick 予算で有界に。一時停止中にactiveLineIndexが動かない等の否定窓はtickUntil(100, …) == false。negative— 不在を保証する機構を待つstop()後は届かない: presenter が購読する publisher にhandleEvents(receiveCancel:)を挟みCollector<Void>に記録、stop()後にwaitForCount(1)で 購読解除そのもの を待つ。以後のsendは誰にも届かないので素の#expectで足りる(AppPresenterTests、ConfigStatusPresenterTests、HeaderPresenterTests、LyricsPresenterTests)。settle、その間の記録に再トリガーが無いことを assert する。同一 pipeline の順序保証が番兵を証明にする(HeaderPresenterDuplicateTests、LyricsPresenterDuplicateTests)。WallpaperPresenterTests3 箇所): ループ分岐は presenter の状態を変えないので、AVPlayer.rateの KVO をCollectorに記録してloopCurrent()のplay()が再発火するのを待ってからwallpaperURL不変を assert。advance してしまう回帰は旧 player の rate が動かず time limit で落ちる — 空虚に通らない。Tests/PresentersTests/TestSupport/WaitUntil.swiftは削除。in-process の状態に対する期限ポーリングはツリーに残っていない。全体実行で見つかった hang
初回の
swift test(全体)が 13 分、CPU 0% で止まった(time limit の報告も無し)。sampleでProcessLockTests.reacquireAfterCleanupがProcess.waitUntilExit()→CFRunLoopRunに留まっているのを確認 — 子 perl は既に回収済み。原因: テストを
async化したことでawait pollUntilの後に 別の協調スレッドで再開 する。waitUntilExit()は呼び出しスレッドの run loop を回すが、Foundation は終了通知を 起動したスレッド に配るため join が戻らない。cancel は run loop の中には届かないので.timeLimitも効かない。6 ターゲットの filter 実行では継続がたまたま起動スレッドに戻っていたので通っていた。修正は本ステップの規則そのもの:
terminationHandlerはテストが持つ callback なのでrun()前にCollector<Void>へ記録し、waitForExit()で待つ(DarwinGatewayTests/LaunchedProcess.swift)。DarwinGatewayProcessTestsの同型 2 箇所も同じく。CLAUDE.md/AGENTS.mdに「awaitの後にwaitUntilExit()を呼ばない」を追記。検証
