# Phase 1 Plan 01: WorkflowStateManager Summary
|
||||
|
||||
**WorkflowStateManager 实现原子写入、备份轮转和崩溃恢复的状态管理**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 5 min
|
||||
- **Started:** 2026-03-13T09:12:34Z
|
||||
- **Completed:** 2026-03-13T09:17:28Z
|
||||
- **Tasks:** 3
|
||||
- **Files modified:** 3
|
||||
|
||||
## Accomplishments
|
||||
- WorkflowStateManager with atomic write pattern (tempfile + os.replace)
|
||||
- Backup rotation for crash recovery (workflow_state.json -> .bak)
|
||||
- Fallback loading when main file is corrupted
|
||||
- get_or_create for idempotent state creation
|
||||
- 90% test coverage (20 tests)
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 1: Write failing tests** - `246e403` (test)
|
||||
2. **Task 2: Implement WorkflowStateManager** - `624cd76` (feat)
|
||||
3. **Task 3: Export from package** - `0dbb0c4` (refactor)
|
||||
|
||||
**Plan metadata:** (pending final commit)
|
||||
|
||||
_Note: TDD tasks had test -> feat -> refactor commits_
|
||||
|
||||
## Files Created/Modified
|
||||
- `kb_pipeline/state.py` - WorkflowStateManager with atomic write, backup rotation, and fallback loading
|
||||
- `kb_pipeline/__init__.py` - Added WorkflowStateManager to package exports
|
||||
- `tests/test_pipeline/test_state.py` - 20 test cases covering all functionality
|
||||
|
||||
## Decisions Made
|
||||
- Followed gsd-openclaw reference implementation for atomic write pattern
|
||||
- Return None instead of raising exception when no state file exists (simpler API)
|
||||
- Silently fallback to backup on JSON parse errors (robustness over strictness)
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 1 - Bug] Fixed test case for backup fallback**
|
||||
- **Found during:** Task 2 (GREEN phase)
|
||||
- **Issue:** Test `test_load_falls_back_to_backup_on_corruption` expected backup to exist after single save, but backup is only created on second save
|
||||
- **Fix:** Modified test to save twice before corrupting main file, ensuring backup exists
|
||||
- **Files modified:** tests/test_pipeline/test_state.py
|
||||
- **Verification:** All 20 tests pass
|
||||
- **Committed in:** 624cd76 (Task 2 commit)
|
||||
|
||||
---
|
||||
|
||||
**Total deviations:** 1 auto-fixed (1 bug)
|
||||
**Impact on plan:** Minor test fix, no scope creep
|
||||
|
||||
## Issues Encountered
|
||||
- pytest not found in system PATH - used project's .venv/bin/pytest instead
|
||||
|
||||
## User Setup Required
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- State management foundation complete
|
||||
- Ready for pipeline executor implementation
|
||||
- Can now track step completion status with crash recovery
|
||||
|
||||
