Motivation:
c22c6b845d introduced support for
UDP_SEGMENT but did restrict it to continous buffers. This is not needed
as it is also fine to use CompositeByteBuf
Modifications:
- Allow to use CompositeByteBuf as well
- Add unit test
Result:
More flexible usage of segmented datagrams possible
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 (native omitted - reserved keyword in Java)
io.netty.transport.kqueue (native omitted - reserved keyword in Java)
io.netty.transport.unix.common (native omitted - reserved keyword in Java)
io.netty.transport.rxtx
io.netty.transport.sctp
io.netty.transport.udt
Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately
in your module-info file.
