feat(patterns): implement PatternLoader with JSON-based pattern management (STAGE 2)
Integrate PatternLoader into analyzer.py to enable JSON-based error pattern
management with hot-reload capability, while preserving fallback to hardcoded
patterns for reliability.
Features:
- JSON-based pattern definitions with schema validation
- Hot-reload capability without restart
- Priority-based pattern matching (higher priority checked first)
- Multi-directory support (builtin, community, custom)
- Backward compatible with fallback to hardcoded PATTERNS
Implementation:
- pattern_loader.py: Core PatternLoader class (309 lines)
- load(): Load patterns from JSON files with schema validation
- match(): Match error against patterns (priority-sorted)
- reload_if_changed(): Hot-reload on file modification
- get_stats(): Pattern statistics and categorization
- patterns/schema.json: JSON schema definition
- Required fields: id, regex, error_key, priority, category
- Optional fields: has_groups, tags, notes
- Validation: unique IDs, valid priority range (0-100), valid categories
- patterns/builtin/core.json: Migrated 21 existing patterns
- Priority distribution: 9 high (80-100), 12 medium (50-79)
- Category distribution: 7 data_type, 3 memory, 3 workflow, 2 model_loading, etc.
- tests/test_pattern_loader.py: Comprehensive test suite (9 tests)
- All tests passed ✅
Integration with analyzer.py:
- Updated ErrorAnalyzer.analyze():
- Try PatternLoader first (JSON patterns)
- Fallback to hardcoded PATTERNS on any error
- Ensures error analysis always works
- Added ErrorAnalyzer.reload_patterns():
- Public API for hot-reload
- Returns True if patterns reloaded
Test Results:
✅ All 9 unit tests passed
✅ Manual integration test passed
✅ 21 patterns loaded from core.json
✅ Error detection working correctly (CUDA OOM, validation errors)
✅ Hot-reload functionality verified
✅ Zero performance regression (<1ms pattern matching)
Architecture:
- Preserves fallback mechanism (learned from STAGE 1)
- Priority-based sorting prevents false positives
- Schema validation catches errors early
- Graceful error handling (never crashes)
Next Steps:
- STAGE 3: F12 Pattern Expansion (35+ community patterns)
- After STAGE 1+2 stable for 3+ days
