- Add nano-vectordb and networkx to pyproject.toml dependencies
- Replace dynamic imports with direct imports for 4 default storage implementations
- Improve startup performance while maintaining backward compatibility
Add "allow" to the list of recognized SSL modes in PostgreSQL connection helper. Previously, ssl_mode="allow" would fall through to "Unknown SSL mode" warning. Now it's properly handled alongside "require" and "prefer" modes.
- Fix JSON parsing errors caused by :: characters in data content
- Implement precise agtype string parsing using rfind() to separate JSON content from type identifiers
- Add robust error handling for malformed JSON in graph data
- Remove entity_type field from entities collections
- Remove weight field from relationships collections
- Update schema definitions and index creation logic
- Maintain backward compatibility with existing data via dynamic fields
- Update extract_entities function in operate.py to use 1.0 as default weight
- Fix Neo4j implementation to use 1.0 instead of 0.0 for missing edge weights
- Fix Memgraph implementation to use 1.0 instead of 0.0 for missing edge weights
- Ensures consistent non-zero default weights across all graph storage backends
- The previous implementation of the shared Redis connection pool had a critical issue where any Redis storage instance would disconnect the global shared pool upon closing. This caused `ConnectionError` exceptions for other instances still using the pool.
- This commit resolves the issue by introducing a reference counting mechanism in `RedisConnectionManager`.
- Change cleanup condition from count == 1 to count == 0 to properly
remove reused locks from cleanup list
- Fix RuntimeError: Attempting to release lock for xxxx more times than it was acquired
Refactored the `KeyedUnifiedLock` to be generic and support dynamic namespaces. This decouples the locking mechanism from a specific "GraphDB" implementation, allowing it to be reused across different components and workspaces safely.
Key changes:
- `KeyedUnifiedLock` now takes a `namespace` parameter on lock acquisition.
- Renamed `_graph_db_lock_keyed` to a more generic _storage_keyed_lock`
- Replaced `get_graph_db_lock_keyed` with get_storage_keyed_lock` to support namespaces
- Add CLEANUP_THRESHOLD constant (100) to control cleanup frequency
- Modify _release_shared_raw_mp_lock to only scan when cleanup list exceeds threshold
- Modify _release_async_lock to only scan when cleanup list exceeds threshold
