Summary of Changes
Hello @wazir-ahmed, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request enhances ProxySQL's query handling capabilities by enabling it to directly respond to SHOW STATUS LIKE 'Ssl_version' queries. This change eliminates the need for ProxySQL to forward these specific queries to a backend server, improving efficiency and reducing unnecessary network traffic. The update also includes a new dedicated test case to ensure the correct behavior and refactors common test utility functions for better code organization.
Highlights
- Direct Handling of SSL Version Queries: ProxySQL now directly intercepts and handles
SHOW STATUS LIKE 'Ssl_version'queries, providing the SSL version information without needing to forward the query to a backend MySQL server. - Accurate SSL Version Reporting: The implementation ensures that if the client connection is encrypted, the actual SSL version (e.g., TLSv1.2) is returned; otherwise, an empty string is provided for the 'Ssl_version' value.
- New Test Coverage for SSL Queries: A comprehensive new TAP test (
mysql-show_ssl_version-t.cpp) has been added to validate this new functionality, covering various query casings and ensuring no backend interaction occurs. - Test Utility Refactoring: Common utility functions like
init_mysql_connandrun_qhave been centralized intest/tap/tap/utils.cppandutils.h, leading to their removal from multiple individual test files and improving overall test infrastructure maintainability.
