Pull Request Review:

Title:

The title of the pull request is clear and concise, indicating that the purpose of the changes is to fix synchronization issues related to locking tables between cn (coordinator node) and dn (data node).

Body:

The body of the pull request includes information about the type of PR, the specific issue it addresses (#2925), and the reason for the changes, which is to fix the synchronization of lock tables between cn and dn. It would be beneficial to provide more context or details about the issue being fixed for better understanding.

Changes:

1. In service_remote.go:

   • The changes made in this file involve modifying the getLocalLockTable function to handle cases where the lock table is not found. The addition of l, err = s.getLockTableWithCreate(req.LockTable.Table, true) and the subsequent check for errors and changes in the lock table is a good improvement. However, the error handling could be enhanced by providing more specific error messages or logging to aid in debugging.

2. In service_test.go:

   • The addition of the TestReLockSuccWithKeepBindTimeout test function is aimed at testing the behavior of locking tables under certain conditions. While the test scenario seems valid, it's important to ensure that the test is comprehensive and covers edge cases to guarantee the reliability of the locking mechanism.

Suggestions for Improvement:

1. Error Handling Improvement:

   • Enhance error handling by providing detailed error messages or logging information to facilitate troubleshooting and debugging in case of failures.

2. Test Coverage:

   • Ensure that the newly added test TestReLockSuccWithKeepBindTimeout covers a wide range of scenarios, including edge cases, to validate the locking mechanism thoroughly.

3. Code Optimization:

   • Consider refactoring the code to improve readability and maintainability. This could involve breaking down complex logic into smaller, more manageable functions or adding comments to clarify the purpose of specific code blocks.

4. Security Consideration:

   • Ensure that the synchronization of lock tables does not introduce any security vulnerabilities, such as race conditions or unauthorized access to locked resources. Perform thorough security testing to identify and mitigate any potential risks.

By addressing these suggestions, the pull request can be further improved in terms of code quality, reliability, and security.
