0909878581 Read only when requested (read-on-demand)
This pull request introduces a new operation called read() that replaces the existing inbound traffic control method. EventLoop now performs socket reads only when the read() operation has been issued. Once the requested read() operation is actually performed, EventLoop triggers an inboundBufferSuspended event that tells the handlers that the requested read() operation has been performed and the inbound traffic has been suspended again. A handler can decide to continue reading or not.

Unlike other outbound operations, read() does not use ChannelFuture at all to avoid GC cost. If there's a good reason to create a new future per read at the GC cost, I'll change this.

This pull request consequently removes the readable property in ChannelHandlerContext, which means how the traffic control works changed significantly.

This pull request also adds a new configuration property ChannelOption.AUTO_READ whose default value is true. If true, Netty will call ctx.read() for you. If you need a close control over when read() is called, you can set it to false.

Another interesting fact is that non-terminal handlers do not really need to call read() at all. Only the last inbound handler will have to call it, and that's just enough. Actually, you don't even need to call it at the last handler in most cases because of the ChannelOption.AUTO_READ mentioned above.

There's no serious backward compatibility issue. If the compiler complains your handler does not implement the read() method, add the following:

public void read(ChannelHandlerContext ctx) throws Exception {
    ctx.read();
}

Note that this pull request certainly makes bounded inbound buffer support very easy, but itself does not add the bounded inbound buffer support.

e59ac8e79b Do not call inbound event methods directly
- Fixes #831

This commit ensures the following events are never triggered as a direct
invocation if they are triggered via ChannelPipeline.fire*():

- channelInactive
- channelUnregistered
- exceptionCaught

This commit also fixes the following issues surfaced by this fix:

- Embedded channel implementations run scheduled tasks too early
- SpdySessionHandlerTest tries to generate inbound data even after the
  channel is closed.
- AioSocketChannel enters into an infinite loop on I/O error.

b47fc77522 Add PooledByteBufAllocator + microbenchmark module
This pull request introduces the new default ByteBufAllocator implementation based on jemalloc, with a some differences:

* Minimum possible buffer capacity is 16 (jemalloc: 2)
* Uses binary heap with random branching (jemalloc: red-black tree)
* No thread-local cache yet (jemalloc has thread-local cache)
* Default page size is 8 KiB (jemalloc: 4 KiB)
* Default chunk size is 16 MiB (jemalloc: 2 MiB)
* Cannot allocate a buffer bigger than the chunk size (jemalloc: possible) because we don't have control over memory layout in Java. A user can work around this issue by creating a composite buffer, but it's not always a feasible option. Although 16 MiB is a pretty big default, a user's handler might need to deal with the bounded buffers when the user wants to deal with a large message.

Also, to ensure the new allocator performs good enough, I wrote a microbenchmark for it and made it a dedicated Maven module. It uses Google's Caliper framework to run and publish the test result (example)

Miscellaneous changes:

* Made some ByteBuf implementations public so that those who implements a new allocator can make use of them.
* Added ByteBufAllocator.compositeBuffer() and its variants.
* ByteBufAllocator.ioBuffer() creates a buffer with 0 capacity.
