1. Fix the issue of read-write sets not being removed after transaction penalties

After conducting code reviews and debugging, we identified that the logic for transaction penalties was missing a cleanup operation for the read-write sets. We have added the cleanup logic in the relevant module and performed unit tests to ensure that the read-write sets can be correctly removed after a transaction penalty.

2. Fix the incorrect handling of time limits during parallel transaction processing

By analyzing the scheduling logic for parallel processing, we discovered a logical error in the calculation of time limits. We have corrected the method for calculating time limits and added relevant boundary tests to ensure that time limits are accurately applied during parallel processing.

3. Fix the abnormal transaction management mechanism in the transaction processing workflow

Through an in-depth analysis of the transaction management module, we found that there were race conditions in the management of transaction states. We have restructured the state machine for transaction management to ensure that transactions can be correctly committed or rolled back under high concurrency. Additionally, we have implemented monitoring and logging to facilitate the tracking and analysis of any future issues.
