Summary

  • Accept both Windows service-wrapper launch shapes that OpenCodex generates.
  • Require source installs that declare OCX_CLI to keep using the Bun + CLI launch form.
  • Accept standalone installs whose executable handles start directly.
  • Preserve fail-closed behavior for inconsistent or malformed wrappers.
  • Add regression coverage using the production standalone-wrapper generator.
  • Document the two valid Windows wrapper forms in the service ownership contract.

Closes #6237

Verification

  • bun test tests/codex-integration/codex-service-manager-probe.test.ts tests/service/standalone-service.test.ts

    • 65 passed, 1 platform-specific skip, 0 failed.
  • bun run typecheck

    • Passed.
  • bun run structure:check

    • Passed.
  • bun run privacy:scan

    • Passed.
  • git diff --check

    • Passed.
  • bun run test:changed

    • Selected 1326 of 1858 test files and reached the repository's 900-second suite limit (exit 124).
    • The reported failures were outside the changed service-probe path, including proxy/DNS-sensitive provider tests and Responses compaction tests.
    • The focused service-manager and standalone-wrapper regression suites completed successfully as listed above.
  • Review follow-up (14f88eb3b)

    • Strengthened the production standalone-wrapper regression to require exactly one ownership claim with the scheduler backend.
    • Documented that the generated OCX_CLI set line, rather than Bun runtime provenance, selects the expected launch shape.
    • Re-ran the focused service-manager and standalone-wrapper suites: 65 passed, 1 platform-specific skip, 0 failed.
    • Re-ran bun run typecheck, bun run structure:check, and bun run privacy:scan; all passed.

Review follow-up (6ecb2475b)

  • Tightened source-wrapper matching to the exact generated launch command, including the generated log redirection, so appended shell commands are rejected.
  • Required unique, quoted, non-empty OCX_BUN and OCX_CLI assignments before accepting the source launch shape.
  • Updated the standalone mixed-launch regression to provide matching scheduler state, isolating launch-shape rejection.
  • Updated hand-written source fixtures to match the production generator.

Verification for this follow-up:

  • bun test tests/codex-integration/codex-service-manager-probe.test.ts tests/service/standalone-service.test.ts
    • 79 passed, 1 platform-specific skip, 0 failed.
  • bun run typecheck
    • Passed.
  • bun run structure:check
    • Passed.
  • bun run privacy:scan
    • Passed.
  • bun test tests/ci-workflows/file-size-ratchet.test.ts
    • 9 passed, 0 failed.
  • git diff --check
    • Passed.
  • bun run test:changed was not rerun: the previously documented run selected 1326 of 1858 files and reached the repository's 900-second limit; this follow-up is limited to the reviewed wrapper-matching cases and their focused fixtures.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • Required local validation passed; commands, results, and any full-suite exception are documented.

  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

  • Bug Fixes
    • Windows service-manager detection recognizes package-installed wrappers that launch the source CLI and standalone wrappers that start the executable directly.
    • Standalone wrappers are recognized only when their launch configuration matches the expected format and agrees with valid scheduler install state. Detection also checks that the scheduled task’s action matches the expected launcher. Missing, malformed, or inconsistent information leaves the service status unknown.
  • Documentation
    • Clarified that detection cannot verify whether an executable has been replaced or a junction retargeted after its path was recorded.

📝 Walkthrough

Walkthrough

The Windows ownership probe now recognizes generated source and standalone wrappers. Standalone wrappers must match the expected launch structure and valid scheduler state. The probe returns unknown when the wrapper, registered task action, or install evidence is missing, invalid, unreadable, or inconsistent.

Changes

Windows wrapper ownership probe

Layer / File(s) Summary
Wrapper launch validation
src/service-manager-probe.ts
The probe validates wrapper assignments, launch commands, generated markers, and runtime paths. It accepts source launches with a valid CLI assignment and port, and validates standalone launch structure.
Task action and scheduler evidence
src/service/windows-taskxml.ts, src/service-manager-probe.ts
Registered task actions must match the generated launcher action. Standalone launches require an absolute .exe path that matches valid version-2 scheduler state with a null CLI path. Optional statePaths pass through the Windows probe. Invalid, unreadable, or mismatched evidence returns unknown.
Validation coverage and evidence limits
tests/codex-integration/codex-service-manager-probe*.test.ts, structure/ops/service-and-sidecars.md
Integration tests use production-generated wrappers and task XML to cover valid source and standalone launches, and malformed or inconsistent wrapper, task, and state evidence. The documentation states that lexical-path agreement does not establish file identity.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 0401a

The Windows ownership probe can report a service as present despite an executable-path mismatch or a registered launcher that differs from the staged launcher. Correct both checks before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 0401a

The new ownership path has substantial consistency checks, and no introduced attack path was established. Its security still depends on who can change the Windows service files, install state, and registered task; those permissions were not established by the available evidence.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed decision can affect whether a Windows installation is treated as owned by the native preflight. The inspected path compares against the current service homes; evidence does not establish access by another user or tenant.

Trust Boundaries and Controls

  • observed — Standalone ownership requires corroborating wrapper and scheduler-state values; a registered task with staged XML must also pass the single-action command check. Invalid or unreadable standalone state returns unknown.

Resilience and Maintainability Implications

  • observed — Unreadable or malformed state, conflicting state homes, and a manager backend that disagrees with recorded state prevent a positive native-ownership decision.

Hardening Proposals

  • proposed — If ownership recognition must resist another local principal, establish and test the effective Windows permissions on state, wrapper, launcher, and task registration; consider file-identity checks where retargeted paths are in scope. The available evidence does not show that such a principal can alter these artifacts.

리뷰 · 우선순위 74 / 80

이 PR은 Windows 단독 실행 파일로 깐 OpenCodex가 서비스를 설치한 뒤, ocx sync가 “래퍼가 우리가 만든 게 아니다”며 설정을 안 바꾸던 버그를 고칩니다. 만들어 주는 쪽과 검사하는 쪽이 서로 다른 문장을 보고 있었습니다. 단독 설치는 CLI 소스 파일이 없어서 "%OCX_BUN%" start ...만 쓰는데, 소유권 검사는 "%OCX_BUN%" "%OCX_CLI%" start ...만 인정했습니다. 그래서 OpenCodex가 직접 만든 opencodex-service.cmd도 unknown이 됐고, 동기화가 거절됐습니다. 지금은 OCX_CLI 줄이 없으면 단독 형태를, 있으면 소스 형태를 보고, 둘 다 아니면 예전처럼 막습니다. 테스트는 실제 buildWindowsServiceScript로 만든 단독 래퍼가 present가 되는지, 소스 래퍼에서 CLI 인자만 뺀 것은 unknown인지 확인합니다. 운영 계약 문서에도 두 형태를 적어 두었습니다. base는 dev이고 #6237을 닫습니다. types/config 분할·프리뷰 배포와는 무관합니다.

라인 - tests/codex-integration/codex-service-manager-probe.test.ts a production-generated standalone wrapper is accepted: kind === "present"만 봅니다. 홈 경로가 비었는지, 클레임이 하나인지, 스케줄러 백엔드인지는 안 봅니다. 같은 파일의 소스 체인 테스트는 홈까지 맞춰 보는데, 단독 쪽만 얇습니다. 단독 설치에서 sync가 막히던 이유가 “래퍼 거절”이라 present만으로도 회귀는 잡히지만, 홈 추출까지 깨지면 이 테스트는 통과한 채로 남을 수 있습니다.

라인 - src/service-manager-probe.ts wrapperLooksGenerated: 갈림표가 bunRuntimeSource가 아니라 OCX_CLI set 줄의 유무입니다. 생성기는 둘을 같이 맞추지만, 사람이 set "OCX_CLI=..."만 넣고 실행 줄은 "%OCX_BUN%" start로 두면 unknown이 됩니다. 반대로 빈 set "OCX_CLI="는 batchSetValue가 ""를 돌려서 소스 형태로 보내고, 실행 줄이 단독이면 또 unknown입니다. 닫힘 방향은 맞는데, “런타임 출처”가 아니라 “CLI 환경 변수 줄”이 기준이라는 점은 나중에 읽는 사람이 헷갈릴 수 있습니다.

라인 - 검증 기록의 bun run test:changed: 900초 한도에 걸려 exit 124입니다. 바뀐 서비스 프로브·단독 래퍼 쪽 집중 테스트와 typecheck/structure/privacy는 초록이라고 적혀 있습니다. CI에 올라온 hygiene·enforce-target 등은 통과 상태입니다.

메인테이너의 판단이 필요한 지점

집중 테스트 + typecheck로 머지할지, test:changed 한도 초과를 다시 돌려 볼지는 선택입니다. 작성자가 실패한 항목은 프록시/DNS·Responses 쪽이라 이번 diff와 무관하다고 적었습니다. OCX_CLI 유무로 갈라 타는 기준을 주석 한 줄로 고정할지도 선택입니다. 같은 주제의 열린 중복 PR은 보이지 않습니다. 닫을 무효·중복 PR은 없습니다.

너의 추천

생성기·검사기 맞춤과 fail-closed 갈림은 유지하세요. 단독 present 테스트에 홈(또는 claims 길이·backend) 단언을 한두 줄 더 넣으면 더 안전합니다. 가능하면 wrapperLooksGenerated 옆에 “OCX_CLI set 줄이 기준이고 bunRuntimeSource가 아니다”를 짧게 적어 두세요. 그 정도만 보강한 뒤 머지해도 됩니다. base dev 유지는 맞습니다.

Addressed the review follow-up in 14f88eb3b.

  • Strengthened the production-generated standalone-wrapper regression to assert exactly one ownership claim and the scheduler backend.
  • Documented next to wrapperLooksGenerated that the generated OCX_CLI set line—not Bun runtime provenance—is the discriminator for the expected launch shape.
  • Re-ran the focused service-manager and standalone-wrapper tests: 65 passed, 1 platform-specific skip, 0 failed.
  • Re-ran bun run typecheck, bun run structure:check, and bun run privacy:scan; all passed.

I did not rerun test:changed: the earlier run selected 1326/1858 files and reached the repository's 900-second limit, while this follow-up only strengthens assertions and documentation.

Require one direct Bun launch in a generated wrapper. Cover source and standalone wrappers that contain both launch forms.
@lidge-jun

Copy link
Copy Markdown
Owner

Maintainer follow-up for the RT6 release train (2.73.0): an independent review found that the new direct-launch branch could accept a lookalike wrapper (no OCX_BUN assignment, or an unquoted/mixed OCX_CLI) and, with a leftover scheduler state, treat it as owned. Two commits on top of your head close that: 5dbf827 rejects mixed launch shapes, and ba5d182 requires the generator's standalone wrapper markers and binds the executable to the recorded scheduler install state. Your production-generator test is kept; new negative cases cover the lookalikes. Your original change is unchanged underneath.

Addressed all three CodeRabbit findings in 6ecb2475b.

  • Source wrappers now match the production-generated launch command exactly, including --port, log redirection, and a valid port, so appended shell commands are rejected.
  • Source wrappers now require unique, quoted, non-empty OCX_BUN and OCX_CLI assignments.
  • The standalone mixed-launch regression now supplies matching scheduler state, so it specifically proves launch-shape rejection.
  • Hand-written source fixtures now match the production generator.

Verification:

  • bun test tests/codex-integration/codex-service-manager-probe.test.ts tests/service/standalone-service.test.ts — 79 passed, 1 platform-specific skip, 0 failed.
  • bun run typecheck — passed.
  • bun run structure:check — passed.
  • bun run privacy:scan — passed.
  • bun test tests/ci-workflows/file-size-ratchet.test.ts — 9 passed, 0 failed.
  • git diff --check — passed.

I did not rerun test:changed: the previously documented run selected 1326/1858 files and hit the repository's 900-second limit. This follow-up is limited to the reviewed wrapper-matching cases and their focused fixtures.

Thanks for 6ecb247. A second independent review found that inserted control-flow lines (goto, exit, call, labels) could still make a lookalike wrapper pass, so a9d76ea (on top of your commit) checks the standalone wrapper's control-flow lines in generator order, with negative tests for each. A production-generated source wrapper is still accepted. Remaining documented limit: install state records a path, not a file identity, so a retargeted junction at that path cannot be told apart.

Reject whitespace that changes the standalone executable path.

If the wrapper contains set "OCX_BUN= C:\OpenCodex\ocx.exe", generatedBatchSetValue trims the leading space. The probe can then match C:\OpenCodex\ocx.exe against the runtime assignment and scheduler state, although the batch variable contains a different executable path. Reject leading or trailing whitespace in OCX_BUN and the compared runtime path before normalizing them. Add a regression case with otherwise valid scheduler state.

Compare the registered action with the staged launcher.

If the staged task names launcher A and the registered task names launcher B, both chains can pass walkWindowsChain and name the same homes. Line 898 then accepts B because it compares the registered action with a path extracted from that same registered XML. The probe reports the staged claim as present, although Task Scheduler launches B.

Extract the launcher from the staged XML and require the registered action to name that launcher. Keep the separate registered-chain validation to check the files behind the action. Add a regression test with two valid launchers under the configuration directory that name the same homes.

Carries #6238 by @lcBreathe (fixes #6237): the Windows standalone service wrapper is accepted by the ownership probe, and only a wrapper and registered task that match the standalone generator (quoted OCX_BUN assignment, generator markers and control flow, executable bound to the recorded install state, single wscript.exe Exec action with the exact launcher arguments) can claim ownership.
