Contributions summary:Javier focused on improving the `Query_Cache` component of the ProxySQL project, which is a high-performance MySQL proxy. Their work primarily involved fixing bugs related to packet handling and data conversion between EOF and OK packets, especially in scenarios involving clients using or not using `CLIENT_DEPRECATE_EOF`. They also added tests to validate the correct handling of warnings and status flags during these packet conversions and implemented new functionality such as the soft TTL for query cache entries. These changes enhanced the stability and functionality of the query caching mechanism.
