# Phase 04 Plan 01: BaseProcessor and ParseProcessor Summary
|
|
|
|
**Unified BaseProcessor abstract class and ParseProcessor implementation establishing the foundation for pipeline architecture**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 5 min
|
|
- **Started:** 2026-03-13T15:09:46Z
|
|
- **Completed:** 2026-03-13T15:14:40Z
|
|
- **Tasks:** 3
|
|
- **Files modified:** 6
|
|
|
|
## Accomplishments
|
|
- BaseProcessor abstract class defining unified interface for all processors
|
|
- ParseProcessor correctly wrapping LinkParser for Bilibili/Zhihu URL parsing
|
|
- ParseInput/ParseOutput schemas with proper validation
|
|
- All processors exportable from kb_pipeline.processors module
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Define BaseProcessor abstract class** - `3ad2576` (test/feat)
|
|
2. **Task 2: Add ParseInput and ParseOutput schemas** - `efddef9` (feat)
|
|
3. **Task 3: Implement ParseProcessor with __init__.py export** - `06d36fc` (feat)
|
|
|
|
**Plan metadata:** pending (docs: complete plan)
|
|
|
|
_Note: TDD tasks may have multiple commits (test -> feat -> refactor)_
|
|
|
|
## Files Created/Modified
|
|
- `kb_pipeline/processors/base.py` - Abstract base class with STEP_NAME and process() method
|
|
- `kb_pipeline/processors/parse.py` - ParseProcessor wrapping LinkParser
|
|
- `kb_pipeline/processors/__init__.py` - Module exports (BaseProcessor, ParseProcessor, ASRProcessor)
|
|
- `kb_pipeline/schemas.py` - Added ParseInput and ParseOutput schemas
|
|
- `tests/test_processors/test_base.py` - Tests for BaseProcessor abstract behavior
|
|
- `tests/test_processors/test_parse.py` - Tests for ParseProcessor URL parsing
|
|
|
|
## Decisions Made
|
|
- BaseProcessor uses ABC with @abstractmethod to enforce process() implementation
|
|
- STEP_NAME as class attribute (matches existing ASRProcessor pattern)
|
|
- ParseInput content_id/platform default to empty (populated after parsing)
|
|
- No retry logic in BaseProcessor (belongs in concrete implementations)
|
|
- State recording optional (only when state_manager provided)
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
- Test mock path needed adjustment: mock `kb_pipeline.processors.base.get_settings` instead of `kb_pipeline.processors.parse.get_settings` because BaseProcessor.__init__ calls get_settings()
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Processor interface established, ready for additional processor implementations
|
|
- ParseProcessor provides URL parsing for downstream download/ASR steps
|
|
- State management integration tested and working
|
