- ChannelInboundHandler and ChannelOutboundHandler does not have a type
parameter anymore.
- User should implement ChannelInboundMessageHandler or
ChannelOutboundMessageHandler.
- 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)
- SslHandler always begins handshake unless startTls is true
- Removed issueHandshake property
- If a user wants to start handshake later, he/she has to add
SslHandler later.
- Removed enableRenegotiation property
- JDK upgrade fixes the security vulnerability - no need to complicate
our code
- Some property name changes
- getSSLEngineInboundCloseFuture() -> sslCloseFuture()
- Updated securechat example
- Added timeout for handshake and close_notify for better security
- However, it's currently hard-coded. Will make it a property later.
- Some tests like SpdySessionHandlerTest accesses outbound buffer
even before the outbound buffer is initialized by
AbstractEmbeddedChannel's subclasses, leading to NPE at <init>.
To fix this problem, subclasses now pass the outbound buffer as
a constructor parameter to AbstractEmbeddedChannel.
- Added EventExecutor.inEventLoop(Thread) and replaced executor identity
comparison in DefaultChannelPipeline with it - more elegant IMO
- Removed the test classes that needs rewrite or is of no use
- LoggingHandler now only logs state and operations
- StreamLoggingHandler and MessageLoggingHandler log the buffer content
- Added ChannelOperationHandlerAdapter
- Used by WriteTimeoutHandler
- 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
