Motivation: Each of DefaultChannelPipeline instance creates an head and tail that wraps a handler. These are used to chain together other DefaultChannelHandlerContext that are created once a new ChannelHandler is added. There are a few things here that can be improved in terms of memory usage and initialization time. Modification: - Only generate the name for the tail and head one time as it will never change anyway - Rename DefaultChannelHandlerContext to AbstractChannelHandlerContext and make it abstract - Create a new DefaultChannelHandlerContext that is used when a ChannelHandler is added to the DefaultChannelPipeline - Rename TailHandler to TailContext and HeadHandler to HeadContext and let them extend AbstractChannelHandlerContext. This way we can save 2 object creations per DefaultChannelPipeline Result: - Less memory usage because we have 2 less objects per DefaultChannelPipeline - Faster creation of DefaultChannelPipeline as we not need to generate the name for the head and tail |

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
The 'master' branch is where the development of the latest major version lives on. The development of all other versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
