Motivation: This fixes a bug that would result in an `io.netty.channel.unix.Errors$NativeIoException: connectx(..) failed: Address family not supported by protocol family` error. This happens when the connecting socket is configured to use IPv6 but the address being connected to is IPv4. This can occur because, for instance, Netty and `InetAddress.getLoopbackAddress()` have different preferences for IPv6 vs. IPv4. Modification: Pass the correct ipv6 or ipv4 flags to connectx, depending on whether the socket was created for AF_INET or AF_INET6, rather than relying on the IP version of the destination address. Result: No more issue with TCP FastOpen on MacOS when using addresses of the "wrong" IP version. |

Netty Project
Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

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 OpenJDK 8
- 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+ / 4.1+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>
. For example, the development of 3.9 and 4.1 resides in the branch '3.9' and the branch '4.1' respectively.
Usage with JDK 9+
Netty can be used in modular JDK9+ applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:
io.netty.all
io.netty.buffer
io.netty.codec
io.netty.codec.dns
io.netty.codec.haproxy
io.netty.codec.http
io.netty.codec.http2
io.netty.codec.memcache
io.netty.codec.mqtt
io.netty.codec.redis
io.netty.codec.smtp
io.netty.codec.socks
io.netty.codec.stomp
io.netty.codec.xml
io.netty.common
io.netty.handler
io.netty.handler.proxy
io.netty.resolver
io.netty.resolver.dns
io.netty.transport
io.netty.transport.epoll

Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately
in your module-info
file.
