Format entire codebase with ruff and add type hints across all modules:
- Apply ruff formatting to all Python files (121 files, 17K insertions)
- Add type hints to function signatures throughout lightrag core and API
- Update test suite with improved type annotations and docstrings
- Add pyrightconfig.json for static type checking configuration
- Create prompt_optimized.py and test_extraction_prompt_ab.py test files
- Update ruff.toml and .gitignore for improved linting configuration
- Standardize code style across examples, reproduce scripts, and utilities
• Replace truthy checks with `is not None`
• Handle empty dict edge case properly
• Prevent data reload failures
• Add comprehensive test coverage
• Fix JsonKVStorage and DocStatusStorage
• Reload cleaned data after sanitization
• Update shared memory with clean data
• Add specific surrogate char tests
• Test migration sanitization flow
• Prevent dirty data in memory
- Fast path for clean data (no sanitization)
- Slow path sanitizes during encoding
- Reload shared memory after sanitization
- Custom encoder avoids deep copies
- Comprehensive test coverage
- Add entity_chunks & relation_chunks storage
- Implement KEEP/FIFO limit strategies
- Update env.example with new settings
- Add migration for chunk tracking data
- Support all KV storage
- Add StorageNotInitializedError and PipelineNotInitializedError exceptions
- Update JsonDocStatusStorage to raise clear errors when not initialized
- Update JsonKVStorage to raise clear errors when not initialized
- Error messages now include complete initialization instructions
- Helps users understand and fix initialization issues quickly
Addresses feedback from issue #1933 about improving error clarity
Refactored the LLM cache to a flat Key-Value (KV) structure, replacing the previous nested format. The old structure used the 'mode' as a key and stored specific cache content as JSON nested under it. This change significantly enhances cache recall efficiency.
- Enhance delete implementation in JsonKVStorage by removing immediate persistence in delete operation
- Update documentation for drop method to clarify persistence behavior
- Add abstract delete method to BaseKVStorage
In single-process mode, data updates and persistence were not working properly because the update flags were not being correctly handled between different objects.
