fix(codex): recover proven zero-byte coordinator remnants#2295Ingwannu wants to merge 6 commits into
Conversation
📝 WalkthroughWalkthroughThis change adds immutable Codex coordinator diagnostics, guarded recovery for verified zero-byte remnants, stable-remnant write eligibility, CLI integration, documentation, and regression coverage. ChangesCoordinator recovery
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The recovery command can race with another process: an existing backup may be overwritten, or a live coordinator may be moved after its database handle closes. That could lose recovery evidence or disrupt active coordination, so the PR is not merge-ready until the rename and writer-exclusion sequence is made race-safe.

Inline comments:
In `@docs-site/src/content/docs/reference/cli/lifecycle.md`:
- Around line 165-182: Move the coordinator recovery paragraphs and command
example currently before the `ocx doctor` description to after the introductory
diagnostics paragraph ending around “Run read-only environment and connectivity
diagnostics,” placing them alongside the existing OAuth reliability subsection.
Preserve the coordinator text and ordering otherwise.
- Around line 165-182: Update the ocx doctor sections in the Japanese, Korean,
Russian, and Simplified Chinese lifecycle pages to document coordinator state,
the guarded ocx doctor --recover-zero-byte-coordinator --yes command followed by
ocx sync, refusal conditions, and same-directory .zero-byte-backup-* creation;
remove or correct claims that doctor never applies repairs, using the English
lifecycle text as the source or a placeholder.
Apply the same fix in `@docs-site/src/content/docs/guides/codex-integration.md`
around lines 206 - 232: Covers the missing localized Codex integration guidance
listed in the original comment.
In `@src/cli/dispatch.ts`:
- Around line 175-177: Update the doctor runner in dispatch to return
Number(process.exitCode ?? 0) after runDoctor completes, preserving recovery
refusal exit codes instead of always returning 0. Keep the existing handling for
--fix-codex-runtime and RECOVER_ZERO_BYTE_COORDINATOR_FLAG unchanged.
In `@src/codex/coordinator-doctor.ts`:
- Around line 62-66: Reuse the existing errorCode and isBusy helpers from
transition-state.ts in coordinator-doctor.ts instead of maintaining local
implementations. Export them from transition-state.ts if needed, import both
into coordinator-doctor.ts, remove the duplicate errorCode and
busy-classification logic, and preserve the existing ENOENT checks and
actionable busy-error handling.
- Around line 19-34: Add a non-empty, valid SQLite fixture for immutable URI
handling and use it through inspectCodexCoordinator(). Assert that inspection
leaves no WAL or SHM sidecar files, replacing the ineffective zero-byte fixture
while preserving the existing inspection behavior.
In `@tests/codex-coordinator-doctor.test.ts`:
- Around line 44-54: Update the afterEach teardown to remove all coordinator
zero-byte backup files matching the coordinator path’s .zero-byte-backup-*
pattern, ensuring cleanup runs even when test assertions fail; retain the
existing coordinator and temporary-home cleanup.
- Around line 150-164: Update the test around recoverZeroByteCodexCoordinator to
use a name describing an active SQLite writer and assert the busy refusal reason
containing “the coordinator is busy; stop active sync/service writers and
retry.” Add a separate test that creates the ${coordinatorPath}-journal sidecar
before calling recoverZeroByteCodexCoordinator and asserts the active SQLite
journal sidecar refusal.
In `@tests/doctor.test.ts`:
- Around line 672-684: Update captureDoctor to save process.exitCode without
converting undefined to 0, then restore that exact value in the finally block so
test execution does not leak process state.

Review follow-up is pushed at exact head 322126c. Focused coordinator, doctor, dispatch, and write-lock tests passed 72 of 72; typecheck and privacy scan passed; the docs build completed all 393 pages. The monolithic Bun 1.3.14 test process later hit a runtime epoll error and segfault after roughly 162 seconds; its only named load failure, multi-agent-keep-native-v1, passed 8 of 8 when rerun alone. All eight review threads have been answered and resolved. This remains blocked on fresh exact-head CI and independent maintainer approval; no self-approval or merge. |

Updated onto the current dev tip 69907dd (including #2312) at exact head 5e535ad. The merge was conflict-free. Exact-head verification passed: 105 focused coordinator/doctor/dispatch/write-lock tests, typecheck, privacy scan, diff check, and the 393-page docs build. Fresh CI is running. This remains pending independent maintainer approval; I will not self-approve or self-merge. |

Exact-head CI is now fully green on 5e535ad: Cross-platform CI, macOS, all Linux shards, npm-global smokes, React Doctor, hygiene, privacy/type gates, and target enforcement completed successfully. There are no unresolved review threads. @lidge-jun @Wibias, this remains ready for independent review; I will not self-approve or self-merge. |
