Motivation: So far, we relied on the domain name resolution mechanism provided by JDK. It served its purpose very well, but had the following shortcomings: - Domain name resolution is performed in a blocking manner. This becomes a problem when a user has to connect to thousands of different hosts. e.g. web crawlers - It is impossible to employ an alternative cache/retry policy. e.g. lower/upper bound in TTL, round-robin - It is impossible to employ an alternative name resolution mechanism. e.g. Zookeeper-based name resolver Modification: - Add the resolver API in the new module: netty-resolver - Implement the DNS-based resolver: netty-resolver-dns .. which uses netty-codec-dns - Make ChannelFactory reusable because it's now used by io.netty.bootstrap, io.netty.resolver.dns, and potentially by other modules in the future - Move ChannelFactory from io.netty.bootstrap to io.netty.channel - Deprecate the old ChannelFactory - Add ReflectiveChannelFactory Result: It is trivial to resolve a large number of domain names asynchronously. |

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
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
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.
