- DefaultChannelPipeline uses this information to reject invalid buffer
access in inbound(Message|Byte)Buffer. Otherwise, a user can access
a message buffer when the channel is stream-oriented.
- Because ChannelType cannot be both STREAM and MESSAGE, catch-all
buffer has been removed to avoid confusion and unexpected behavior
(it's already causing headache.)
- As a result, codec embedder needs rework.
... just like we do with byte arrays. toByteBuffer() and
toByteBuffers() had an indeterministic behavior and thus it could not
tell when the returned NIO buffer is shared or not. nioBuffer() always
returns a view buffer of the Netty buffer. The only case where
hasNioBuffer() returns false and nioBuffer() fails is the
CompositeChannelBuffer, which is not very commonly used and *slow*.
- Add EventExecutor and make EventLoop extend it
- Add SingleThreadEventExecutor and MultithreadEventExecutor
- Add EventExecutor's default implementation
- Fixed an API design problem where there is no way to get non-bypass
buffer of desired type
- Add ChannelHandlerContext.eventLoop() for convenience
- Bootstrap and ServerBootstrap handles channel initialization failure
better
- More strict checks for missing @Sharable annotation
- A handler without @Sharable annotation cannot be added more than
once now.
- Added a new convenience method to ChannelInboundstreamHandlerAdapter
- EchoServerHandler uses the new method
- DefaultChannelPipeline calls inboundByteBuffer.discardReadBytes()
when it is sure there's no memory copy involved
- Really attempt to create a queue to determine LTQ can be initialized
in runtime, and cache the result
- Remove unnecessary Class<T> parameter in createQueue()
- Remove unused createQueue(Collection)
- LocalChannel and LocalServerChannel uses it to close themselves on
shutdown
- LocalEcho example does not call close() anymore because the channels
are closed automatically on shutdown
- Exception in this case makes a user less confusing
- To reduce the overhead of filling the stack trace,
NoSuchBufferException has a public pre-constructed instance.
- This is necessary because codec framework sometimes need to support
both type of outbound buffers.
- Fixed a bug where SpdyFrameEncoder did not handle ping messages
- Reduced memory copy in codec embedder (EmbeddedChannel)
- Renamed ChannelBootstrap to Bootstrap
- Renamed ServerChannelBootstrap to ServerBootstrap
- Moved bootstrap classes to io.netty.bootstrap as before
- Moved unfoldAndAdd() to a separate utility class
- Fixed a bug in unfoldAndAdd() where it did not handle ChannelBuffer
correctly
- Previous API did not support the pipeline which contains multiple
MessageToStreamEncoders because there was no way to find the closest
outbound byte buffer. Now you always get the correct buffer even if
the handler that provides the buffer is placed distantly.
For example:
Channel -> MsgAEncoder -> MsgBEncoder -> MsgCEncoder
Msg(A|B|C)Encoder will all have access to the channel's outbound
byte buffer. Previously, it was simply impossible.
- Improved ChannelBufferHolder.toString()
