Contributions summary:Tharanga contributed significantly to the implementation of TLS (Transport Layer Security) support for the memcached server, including the necessary code modifications and integration with OpenSSL. They focused on adding new functions for reading from and writing to sockets within the TLS context and updating the core server logic. Furthermore, the user implemented client connection logging features which can monitor fetch and mutations, which is critical for debugging and performance evaluation. The user made several optimizations, specifically improving the performance of `incr`/`decr` operations and added functionality to add server addresses to the stats output.
