Role in this project:Back-end Developer
Back-end DeveloperContributions:5 reviews, 19 commits, 14 PRs in 2 years 9 months
Contributions summary:Bennett primarily contributed to the Netty project by implementing new features and enhancing existing functionality. They created a `SimpleUserEventChannelHandler` class, improving event handling. The user also improved the logging behavior of the framework by adding a new `ByteBufFormat` option for the `LoggingHandler` to log a hex dump of all written and received ByteBufs or to just display the data as is. Additional contributions include fixing existing issues like the removing of the `Content-Length` header under some conditions and adding an option to allow for duplicate `Content-Length` headers.
