PROFILE
Shubham Sinha
Worked on the percona/percona-server repository, focusing on reliability and security improvements through targeted bug fixes. Addressed issues in C and SQL code, such as correcting quote handling in mysqldump to prevent data corruption and injection vulnerabilities, and enhanced init-file parsing by implementing robust multi-statement processing to reduce syntax errors during startup. Improved diagnostics reliability by resolving access privilege errors in sys.diagnostics() for various configurations, adding automated tests to ensure ongoing stability. Demonstrated strong skills in C++, SQL development, and database administration, consistently applying regression testing and cross-branch coverage to maintain data integrity and operational robustness across environments.

Apr 1, 2025Month: 2025-04. Focused on improving reliability and stability of init-file parsing in percona/percona-server. Implemented a robust multi-statement init file parser, ensuring each statement is parsed independently and properly executed by appending a null character to correctly parse statements, preventing syntax errors and assertion failures. The work reduces deployment risks and improves startup robustness.

Feb 1, 2025In February 2025, focused on correctness and security in the mysqldump data-export path for the percona-server repository. The team fixed incorrect quote handling by ensuring fprintf_string passes the actual quote character to mysql_real_escape_string_quote, added regression tests, and ensured cross-branch coverage for trunk and MySQL 5.7. These changes reduce data corruption risk and injection vulnerabilities, and improve overall reliability of logical dumps.
