Summary

  • Launch an installed Windows tray through its owned wscript.exe launcher with hidden stdio and a bounded timeout.
  • Preserve OCX_TRAY_ENTRY_B64 in the legacy detached-host fallback instead of dropping it through UseShellExecute = true.
  • Drain a stale stop event only after acquiring singleton ownership, enable visual styles, and contain timer-tick I/O failures so the tray loop remains alive.

Closes #2804

Verification

  • RED: bun test tests/windows-tray.test.ts failed because the installed-launch contract did not exist.
  • Mutation RED: changing the launch timeout from 15000ms to 1000ms failed the exact options assertion.
  • GREEN: bun test tests/windows-tray.test.ts — 21 pass, 0 fail, 138 assertions.
  • bun x tsc --noEmit — exit 0.
  • bun run privacy:scan — passed.
  • Real Windows tray execution was not available on this macOS host. The cross-platform tests verify the exact executable, argv, process options, fallback environment contract, stop-event reset placement, and guarded timer shape; they do not claim a Windows 11 visual smoke test.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed. No documentation change is needed for this restoration of documented tray behavior.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. The action log records only the exception type, not paths or payloads.

Summary by CodeRabbit

  • Bug Fixes
    • Improved Windows tray startup reliability by preventing stale stop signals from closing newly launched instances.
    • Added error handling to keep tray updates running when timer operations encounter problems.
    • Reduced visible windows and console interruptions during tray launch.
    • Improved tray rendering consistency on Windows.
    • Improved compatibility when launching the installed Windows tray application.

Launch the owned VBS host with hidden, bounded process options and preserve
the environment in the legacy detached-host fallback. Drain stale stop state
only after singleton ownership and keep timer I/O failures inside the tray UI.

📝 Walkthrough

Walkthrough

The Windows tray now launches the installed VBS launcher through hidden wscript.exe, preserves detached-host environment data, resets stale stop signals, enables WinForms visual styles, and logs timer tick failures. Tests cover the launcher arguments and PowerShell source changes.

Changes

Windows tray fixes

Layer / File(s) Summary
Installed launcher execution
src/tray/windows.ts, tests/windows-tray.test.ts
spawnTray launches the installed VBS launcher through wscript.exe when the launcher exists. The helper uses //B, //NoLogo, hidden execution, ignored stdio, and a 15-second timeout. Tests verify the executable path, arguments, and options.
Detached host process configuration
src/tray/windows.ts
The detached PowerShell host disables shell execution, creates no window, and forwards OCX_TRAY_ENTRY_B64 to the child process.
PowerShell tray lifecycle handling
src/tray/windows-tray.ps1, tests/windows-tray.test.ts
The script enables WinForms visual styles, resets the stop event after singleton acquisition, and logs timer tick failures. Source assertions verify these changes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to f5341

The startup sequence can erase a concurrent stop request, causing the tray to ignore that stop command. This is a bounded but concrete lifecycle correctness risk, so merge should wait for the race to be fixed or explicitly accepted by the owner.

이 PR은 Windows에서 ocx tray install 직후 트레이가 바로 죽어 버리는 버그(#2804)를 고칩니다. 지금 dev(HEAD 577bce695)의 src/tray/windows.ts를 보면 spawnTray가 항상 launchWindowsTrayHost만 탑니다. 그 안의 DETACHED_TRAY_HOST_LAUNCHER$startInfo.UseShellExecute = $true라서 .NET이 ShellExecuteEx로 자식 프로세스를 띄울 때 환경 변수를 버립니다. 그래서 부모가 넣어 준 OCX_TRAY_ENTRY_B64가 호스트에 안 넘어가고, __tray-hostMissing tray host entry로 바로 끝납니다. 그게 이슈에 적힌 “설치했다고 나오는데 3초 만에 안 떠 있음 / 유령 아이콘”의 첫 번째 원인입니다.

두 번째 원인은 src/tray/windows-tray.ps1의 정지 이벤트입니다. signalTrayStop()Local\OpenCodexTrayStop-<hash>를 Set 해 두면, 새 Run 모드 인스턴스가 그 신호를 비우지 않은 채 시작합니다. 3초 타이머 첫 틱에서 WaitOne(0)이 남은 신호를 먹고 Application::Exit()를 호출하니, 방금 켠 트레이가 스스로 종료합니다. 이 PR은 뮤텍스로 싱글톤 소유권을 잡은 뒤에야 $stopEvent.Reset()을 호출합니다. 중복 인스턴스면 그냥 나가므로, 소유자가 아닌 프로세스가 남의 정지 신호를 지우는 일은 없습니다. 이슈 본문이 Mode Stop 분기 직후에 Reset 하자고 한 것보다 위치가 더 안전합니다.

세 번째로 WinForms 쪽을 보강합니다. EnableVisualStyles()를 켜서 컨텍스트 메뉴 그리기를 맞추고, 타이머 틱 안의 Update-TrayState I/O를 try/catch로 감쌉니다. $ErrorActionPreference = "Stop"인 상태에서 heartbeat 파일 잠금 같은 잠깐의 실패가 UI 스레드를 죽여 버리던 경로를 막으려는 것입니다. 액션 로그에는 예외 타입 이름만 남기고 경로·페이로드는 안 씁니다.

런치 경로도 바꿉니다. 설치가 끝난 뒤에는 HKCU Run / 부팅과 같은 opencodex-tray.vbswscript.exe //B //NoLogo로 직접 띄웁니다(launchInstalledWindowsTray). VBS는 WScript.Shell.Run ..., 0, False라서 논블로킹이고, execFileSync 15초 타임아웃·stdio: ignore·windowsHide 계약은 테스트로 고정했습니다. VBS가 없을 때만 예전 detached Bun 호스트 폴백을 쓰는데, 그때는 UseShellExecute = $false + CreateNoWindow + EnvironmentVariables['OCX_TRAY_ENTRY_B64'] 복사로 환경이 살아남게 고쳤습니다. bun test tests/windows-tray.test.ts 21통과 tsc/privacy scan은 초록이고, 실제 Windows 11 화면 스모크는 이 호스트에서 못 돌렸다고 본문에 솔직히 적혀 있습니다.

방금 끝난 bug-PR zero-remaining 캠페인(#2855) 직후라 “남아 있던 버그 PR”은 아니지만, #2804는 플랫폼 체감 버그라 dev에 독립으로 들이기 좋습니다. types/config 분할에 걸려 무효화될 종류도 아닙니다. 다만 지금 hygiene / enforce-target이 empty_catch로 막혀 있고 라벨 intake: hygiene-blocked가 붙어 있어서, 그대로는 머지 게이트를 못 넘습니다.

src/tray/windows-tray.ps1 (EnableVisualStyles) - try { ... } catch { } 빈 catch라 deterministic hygiene의 empty_catch에 걸립니다. 의도적으로 무시하는 호출이라도 로그 한 줄, 주석+rethrow 금지 사유, 또는 $null = ... 형태처럼 게이트가 통과하는 형태로 바꿔야 합니다.

src/tray/windows-tray.ps1 (timer tick 안쪽 Write-ActionLog catch) - 로그 쓰기 실패용 catch도 비어 있습니다. 바깥 try가 이미 UI를 지키므로, 여기도 빈 catch면 같은 hygiene 규칙에 또 걸릴 수 있습니다. 최소한 no-op 이유를 코드로 남기거나 조용히 삼키는 허용 패턴을 쓰세요.

src/tray/windows.ts spawnTray - 설치된 VBS가 있으면 state 인자를 무시하고 설치 시점 스크립트만 띄웁니다. 부팅 경로와 맞추려는 선택이라 맞지만, 재설치 없이 bun/cli 경로만 바뀐 상태면 옛 VBS가 우선됩니다. install/repair가 VBS를 항상 갱신한다는 전제가 문서나 주석에 있으면 이후 기여자가 덜 헷갈립니다.

tests/windows-tray.test.ts - 런처 argv·옵션·폴백 문자열·Reset 위치·타이머 try 모양은 mutation RED까지 잠가 두어 계약이 탄탄합니다. 다만 실제 트레이가 3초 뒤에도 살아 있는지, 유령 아이콘이 사라지는지는 CI/macOS에서 증명되지 않습니다. #2804 재현 환경(Windows) 한 번의 수동 확인이 남아 있습니다.

src/tray/windows.ts buildWindowsTrayRunCommand - 기존 HKCU Run 문자열은 여전히 path.join으로 wscript 경로를 만들고, 새 launchInstalledWindowsTraywin32Path.join을 씁니다. 동작 차이는 작지만 Windows 경로 조립이 두 갈래입니다. 이번 범위 밖에서 맞춰도 됩니다.

메인테이너의 판단이 필요한 지점

너의 추천
empty_catch부터 고쳐서 hygiene/enforce-target을 초록으로 만든 뒤, Windows에서 ocx tray install → 수 초 대기 → ocx tray status가 running이고 우클릭 메뉴가 살아 있는지 한 번 확인하세요. 그다음 dev로 머지하고 #2804를 닫으면 됩니다. types/config 분할과 무관하니 close-dont-rebase 대상이 아닙니다.

P2 Badge Preserve literal-percent paths when launching the tray

When an installed Bun, CLI, or home path contains a literal environment-variable token such as %TEMP%—a legal Windows path already exercised by this test fixture—this branch launches the generated VBS file, whose WScript.Shell.Run expands environment variables in its command string even inside quoted paths. PowerShell therefore receives rewritten paths and the install/start command times out waiting for a heartbeat; before this change, spawnTray used launchWindowsTrayHost with fixed argv and preserved these characters. Keep the fixed-argv launch path here, or otherwise prevent WSH environment expansion.

does not classify the visual-style and fallback-log catches as empty.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Do not discard a stop request during startup.

The -Mode Stop path does not acquire $mutex. It can set $stopEvent after mutex acquisition but before this Reset() call. Reset() then clears the new request, and the tray ignores the stop command.

Serialize the startup reset and stop-event Set() operation with a shared gate, or use a startup handshake that distinguishes stale signals from new requests. The assertion in tests/windows-tray.test.ts, Lines 329-380, checks ordering but not this interleaving.
