1. Fixing the Issue of Conflict Relationship Errors in DAG Structure Parsing During Block Generation and Synchronization

A comprehensive review of the parsing logic for the DAG structure was conducted to identify the root causes of the conflict relationships. A new parsing algorithm was implemented to ensure that concurrent operations are handled correctly during the generation and synchronization phases. Additionally, unit tests and integration tests were added to ensure that the functionality works properly across various scenarios after the fix.

2. Fixing Data Race Issues in the Virtual Machine Instruction Functions of the Needle Language During Concurrent Execution

A code review of the relevant instruction functions was performed to pinpoint the specific locations of data races. Lock mechanisms and other synchronization methods were introduced to ensure data consistency and safety during concurrent execution. The documentation was updated to provide best practices for concurrent programming, helping developers avoid similar issues in the future.
