- Add ChannelOption.ALLOW_HALF_CLOSURE
- If true, ChannelInputShutdownEvent is fired via userEventTriggered()
when the remote peer shuts down its output, and the connection is
not closed until a user calls close() explicitly.
- If false, the connection is closed immediately as it did before.
- Add SocketChannel.isInputShutdown()
- Add & improve test cases related with half-closed sockets
- Reimplemented the test
- Fixed various bugs related with read/accept suspension found while testing
- defaultInterestOps of NioServerSocketChannel should be OP_ACCEPT
- There's no need do deregister and re-register to suspend/resume accept()
- Occational infinite loop with 100% CPU consumption in OioEventLoop, caused by OioSocketChannel
- Even if read/accept is suspended, what's read or accepted should be notified to a user
- Add EventExecutorGroup and EventLoopGroup
- EventExecutor and EventLoop extends EventExecutorGroup and
EventLoopGroup
- They form their own group so that .next() returns itself.
- Rename Bootstrap.eventLoop() to group()
- Rename parameter names such as executor to group
- Rename *EventLoop/Executor to *EventLoop/ExecutorGroup
- Rename *ChildEventLoop/Executor to *EventLoop/Executor
- Used reflection hack to dispatch the tasks submitted by JDK
efficiently. Without hack, there's higher chance of additional
context switches.
- Server side performance improved to the expected level.
- Client side performance issue still under investigation
- Add MessageBuf which replaces java.util.Queue
- Add ChannelBuf which is common type of ByteBuf and ChannelBuf
- ChannelBuffers was renamed to ByteBufs
- Add MessageBufs
- All these changes are going to replace ChannelBufferHolder.
- ChannelBuffer gives a perception that it's a buffer of a
channel, but channel's buffer is now a byte buffer or a message
buffer. Therefore letting it be as is is going to be confusing.
- Also prohibited a user from overriding
ChannelInbound(Byte|Message)HandlerAdapter. If a user wants to do
that, he or she should extend ChannelInboundHandlerAdapter instead.
- In computing, 'stream' means both byte stream and message stream,
which is confusing.
- Also, we were already mixing stream and byte in some places and
it's better use the terms consistently.
(e.g. inboundByteBuffer & inbound stream)
