Pull Request Review:

Title:

The title "Fix halloween" is not descriptive enough. It should provide more context about the specific bug or issue being addressed to help other team members understand the purpose of the pull request at a glance.

Body:

1. The PR type checkbox list is provided, but it seems incomplete as only the "BUG" checkbox is checked. It would be beneficial to ensure all relevant types are considered and checked if applicable.
2. The reference to issue [Tech Request]: Many issues with transaction workspace #14552 is good for tracking purposes.
3. The explanation of "fix bug for halloween" is vague and does not provide detailed information on the bug or how it is fixed. More specific details would be helpful for reviewers and future reference.

Changes:

1. In the txn.go file:

   • The function getInsertedObjectListForTable has been refactored into collectUnCommittedObjects in the txnTable struct. This change seems appropriate for better structuring and encapsulation.
   • However, the refactored function seems to have a logical issue. The stats variable is being reused without reinitialization, which can lead to incorrect data being appended to unCommittedObjects. Each iteration should create a new stats object to avoid this.
   • The continue statements in the if conditions should be replaced with return to exit the loop early and improve readability.
   • The statsList return variable is removed, but it is unclear if this change is intentional. If the function should return a list of stats, this logic needs to be revised.
   • The forEachTableWrites method is not shown in the diff, so it's unclear how it interacts with the changes made.

2. In the txn_table.go file:

   • The call to getInsertedObjectListForTable is replaced with collectUnCommittedObjects, which is a good change for consistency and readability.
   • The error handling for getInsertedObjectListForTable is removed, but error handling for collectUnCommittedObjects is missing. Error handling should be added if necessary to maintain code reliability.

Suggestions for Improvement:

1. Title and Body:

   • Provide a more descriptive title that summarizes the specific bug or issue being fixed.
   • Expand the body to include details about the bug, the impact it had, and how the fix addresses it.

2. Code Changes:

   • Ensure that the logic in the refactored function collectUnCommittedObjects is correct and that each iteration creates a new stats object.
   • Replace continue statements with return for better control flow.
   • Clarify the intention behind removing statsList and ensure the function returns the expected data.
   • Add error handling in collectUnCommittedObjects if required to handle potential errors.
   • Consider adding comments to explain the purpose of the refactored code for better code maintenance and understanding.

3. Testing:

   • Verify that the changes do not introduce any new bugs and that the functionality works as expected.
   • Consider adding unit tests to cover the refactored code to ensure its correctness and prevent regressions.

By addressing the mentioned points and ensuring clarity, correctness, and robustness in the code changes, the pull request can be improved both in terms of quality and maintainability.
