- Extracted some handler methods from ChannelInboundHandler into
ChannelStateHandler
- Extracted some handler methods from ChannelOutboundHandler into
ChannelOperationHandler
- Moved exceptionCaught and userEventTriggered are now in
ChannelHandler
- Channel(Inbound|Outbound)HandlerContext is merged into
ChannelHandlerContext
- ChannelHandlerContext adds direct access methods for inboud and
outbound buffers
- The use of ChannelBufferHolder is minimal now.
- Before: inbound().byteBuffer()
- After: inboundByteBuffer()
- Simpler and better performance
- Bypass buffer types were removed because it just does not work at all
with the thread model.
- All handlers that uses a bypass buffer are broken. Will fix soon.
- CombinedHandlerAdapter does not make sense anymore either because
there are four handler interfaces to consider and often the two
handlers will implement the same handler interface such as
ChannelStateHandler. Thinking of better ways to provide this feature
- The handler you specify with initializer() is actually simply added
to the pipeline and that's all. It's ChannelInitializer which does
additional work. For example, a user can specify just a single
handler with initializer() and it will still work. This is especially
common for Bootstrap, so I renamed initializer to handler, which makes
more sense.
- Removed ones are: IP filer and HTTP multipart codec
- Needs closer code review and polishing
- Sorry. I'll add them back in the next alpha releases
- SSL handler and ChunkedWriteHandler also need more work, but
I really want to make them part of the first alpha because they
are used pretty often by users.
- 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
- 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
- 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()
- Replaced pipeline factories with initializers
- Ported essential parts related with HTTP to the new API
- Replaced ChannelHandlerAdapter.combine() with CombinedChannelHandler
- Fixed a bug where ReplayingDecoder does not notify the next handler
- Fixed a bug where ReplayingDecoder calls wrong callDecode() method
- Added a destination buffer as an argument to AbstractChannel.doRead()
for easier implementation
- Fixed a bug where NioSocketChannel did not try to increase the inbound
buffer size (moved the logic to AbstractChannel)
- Replaced FrameDecoder and OneToOne(Encoder|Decoder) with:
- (Stream|Message)To(String|Message)(Encoder|Decoder)
- Moved the classes in 'codec.frame' up to 'codec'
- Fixed some bugs found while running unit tests
- It does not build a new Channel but just helps bootstrapping it.
- Added shutdown() method for simpler deinitialization
- ServerChannelBootstrap has shorter method names for the parent channel
- Added ChannelInitializer which is supposed to be used with the
builders
- Echo examples use ChannelBuilder and ServerChannelBuilder now
- Replace ChannelFuture.rethrowIfFailed() with sync*()
- Bug fixes
- Added ChannelBufferHolders.(inbound|outbound)BypassBuffer()
- The holder returned by these methods returns the next handler's
buffer. When a handler's new(Inbound|Outbound)Buffer returns
a bypass holder, your inboundBufferUpdated() and flush()
implementation should check if the buffer is a bypass and should not
modify the content of the buffer.
- Channel(Inbound|Outbound)?HandlerAdapter is now abstract.
- A user has to specify the exact inbound/outbound buffer type
- It's because there's no way to determine the best buffer type
- Implemented LoggingHandler using the new API.
- It doesn't dump received or sent messages yet.
- Fixed a bug where DefaultUnsafe.close() does not trigger deregister()
- Fixed a bug where NioSocketChannel.isActive() does not return false
when closed
- Made sure unnecessary interestOps are not OR'd
- Fixed a bug where DefaultChannelFuture.rethrowIfFailed() returns
silently if the future is not done yet - there's no ways to tell
the differences between failure and incompleteness.
- Optimized AbstractChannelBuffer.discardReadBytes()
- Split ChannelHandlerInvoker into ChannelInboundInvoker and
ChannelOutboundInvoker
- Channel implements ChannelOutboundInvoker
- ChannelOutboundInvoker.nextOut() is now out()
- ChannelOutboundHandlerContext.out() is now prevOut()
- Added the outbound operations without future
parameter to ChannelOutboundInvoker for user convenience
- All async operations which requires a ChannelFuture as a parameter
now returns ChannelFuture for user convenience
- Added ChannelFutureFactory.newVoidFuture() to allow a user specify
a dummy future that is of no use
- I'm unsure if it is actually a good idea to introduce it. It might
go away later.
- Made the contract of AbstractChannel.doXXX() much simpler and moved
all common code up to AbstractChannel.DefaultUnsafe
- Added Channel.isOpen()
- Fixed a bug where MultithreadEventLoop always shut down its child
event loops on construction
- Maybe more changes I don't remember :-)
- Channel now creates a ChannelPipeline by itself
I find no reason to allow a user to use one's own pipeline
implementation since I saw nobody does except for the cases where a
user wants to add a user attribute to a channel, which is now covered
by AttributeMap.
- Removed ChannelEvent and its subtypes because they are replaced by
direct method invocation.
- Replaced ChannelSink with Channel.unsafe()
- Various getter renaming (e.g. Channel.getId() -> Channel.id())
- Added ChannelHandlerInvoker interface
- Implemented AbstractChannel and AbstractServerChannel
- Some other changes I don't remember
