Revamp the core API to reduce memory footprint and consumption The API changes made so far turned out to increase the memory footprint and consumption while our intention was actually decreasing them. Memory consumption issue: When there are many connections which does not exchange data frequently, the old Netty 4 API spent a lot more memory than 3 because it always allocates per-handler buffer for each connection unless otherwise explicitly stated by a user. In a usual real world load, a client doesn't always send requests without pausing, so the idea of having a buffer whose life cycle if bound to the life cycle of a connection didn't work as expected. Memory footprint issue: The old Netty 4 API decreased overall memory footprint by a great deal in many cases. It was mainly because the old Netty 4 API did not allocate a new buffer and event object for each read. Instead, it created a new buffer for each handler in a pipeline. This works pretty well as long as the number of handlers in a pipeline is only a few. However, for a highly modular application with many handlers which handles connections which lasts for relatively short period, it actually makes the memory footprint issue much worse. Changes: All in all, this is about retaining all the good changes we made in 4 so far such as better thread model and going back to the way how we dealt with message events in 3. To fix the memory consumption/footprint issue mentioned above, we made a hard decision to break the backward compatibility again with the following changes: - Remove MessageBuf - Merge Buf into ByteBuf - Merge ChannelInboundByte/MessageHandler and ChannelStateHandler into ChannelInboundHandler - Similar changes were made to the adapter classes - Merge ChannelOutboundByte/MessageHandler and ChannelOperationHandler into ChannelOutboundHandler - Similar changes were made to the adapter classes - Introduce MessageList which is similar to `MessageEvent` in Netty 3 - Replace inboundBufferUpdated(ctx) with messageReceived(ctx, MessageList) - Replace flush(ctx, promise) with write(ctx, MessageList, promise) - Remove ByteToByteEncoder/Decoder/Codec - Replaced by MessageToByteEncoder<ByteBuf>, ByteToMessageDecoder<ByteBuf>, and ByteMessageCodec<ByteBuf> - Merge EmbeddedByteChannel and EmbeddedMessageChannel into EmbeddedChannel - Add SimpleChannelInboundHandler which is sometimes more useful than ChannelInboundHandlerAdapter - Bring back Channel.isWritable() from Netty 3 - Add ChannelInboundHandler.channelWritabilityChanges() event - Add RecvByteBufAllocator configuration property - Similar to ReceiveBufferSizePredictor in Netty 3 - Some existing configuration properties such as DatagramChannelConfig.receivePacketSize is gone now. - Remove suspend/resumeIntermediaryDeallocation() in ByteBuf This change would have been impossible without @normanmaurer's help. He fixed, ported, and improved many parts of the changes.

Add an OpenSslEngine and the universal API for enabling SSL Motivation: Some users already use an SSLEngine implementation in finagle-native. It wraps OpenSSL to get higher SSL performance. However, to take advantage of it, finagle-native must be compiled manually, and it means we cannot pull it in as a dependency and thus we cannot test our SslHandler against the OpenSSL-based SSLEngine. For an instance, we had #2216. Because the construction procedures of JDK SSLEngine and OpenSslEngine are very different from each other, we also need to provide a universal way to enable SSL in a Netty application. Modifications: - Pull netty-tcnative in as an optional dependency. http://netty.io/wiki/forked-tomcat-native.html - Backport NativeLibraryLoader from 4.0 - Move OpenSSL-based SSLEngine implementation into our code base. - Copied from finagle-native; originally written by @jpinner et al. - Overall cleanup by @trustin. - Run all SslHandler tests with both default SSLEngine and OpenSslEngine - Add a unified API for creating an SSL context - SslContext allows you to create a new SSLEngine or a new SslHandler with your PKCS#8 key and X.509 certificate chain. - Add JdkSslContext and its subclasses - Add OpenSslServerContext - Add ApplicationProtocolSelector to ensure the future support for NPN (NextProtoNego) and ALPN (Application Layer Protocol Negotiation) on the client-side. - Add SimpleTrustManagerFactory to help a user write a TrustManagerFactory easily, which should be useful for those who need to write an alternative verification mechanism. For example, we can use it to implement an unsafe TrustManagerFactory that accepts self-signed certificates for testing purposes. - Add InsecureTrustManagerFactory and FingerprintTrustManager for quick and dirty testing - Add SelfSignedCertificate class which generates a self-signed X.509 certificate very easily. - Update all our examples to use SslContext.newClient/ServerContext() - SslHandler now logs the chosen cipher suite when handshake is finished. Result: - Cleaner unified API for configuring an SSL client and an SSL server regardless of its internal implementation. - When native libraries are available, OpenSSL-based SSLEngine implementation is selected automatically to take advantage of its performance benefit. - Examples take advantage of this modification and thus are cleaner.
