7b25402e80 Add CompositeByteBuf.addComponent(boolean ...) method to simplify usage
Motivation:

At the moment the user is responsible to increase the writer index of the composite buffer when a new component is added. We should add some methods that handle this for the user as this is the most popular usage of the composite buffer.

Modifications:

Add new methods that autoamtically increase the writerIndex when buffers are added.

Result:

Easier usage of CompositeByteBuf.

e59d0e9efb Introduce CodecOutputList to reduce overhead of encoder/decoder
Motivation:

99dfc9ea79 introduced some code that will more frequently try to forward messages out of the list of decoded messages to reduce latency and memory footprint. Unfortunally this has the side-effect that RecycleableArrayList.clear() will be called more often and so introduce some overhead as ArrayList will null out the array on each call.

Modifications:

- Introduce a CodecOutputList which allows to not null out the array until we recycle it and also allows to access internal array with extra range checks.
- Add benchmark that add elements to different List implementations and clear them

Result:

Less overhead when decode / encode messages.

3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

9f5eb7d698 Add CharSequence operations to ByteBuf
Motivation:

Often users either need to read or write CharSequences to a ByteBuf. We should add methods for this to ByteBuf as we can do some optimizations for this depending on the implementation.

Modifications:

Add setCharSequence, writeCharSequence, getCharSequence and readCharSequence

Result:

Easier reading / writing of CharSequence with ByteBuf.

ce1ae0eb8b Handle the backslash with double quote in JsonObjectDecoder
Motivation:

The double quote may be escaped in a JSON string, but JsonObjectDecoder doesn't handle it. Resolves #5157.

Modifications:

Don't end a JSON string when processing an escaped double quote.

Result:

JsonObjectDecoder can handle backslash and double quote in a JSON string correctly.

d698746609 Add ByteBuf.asReadOnly()
Motivation:

We lately added ByteBuf.isReadOnly() which allows to detect if a buffer is read-only or not. We should add ByteBuf.asReadOnly() to allow easily access a read-only version of a buffer.

Modifications:

- Add ByteBuf.asReadOnly()
- Deprecate Unpooled.unmodifiableBuffer(Bytebuf)

Result:

More consistent api.

6108b7297b Correctly handle ChannelInputShutdownEvent in ReplayingDecoder
Motivation:

b112673554 added ChannelInputShutdownEvent support to ByteToMessageDecoder but missed updating the code for ReplayingDecoder. This has the effect:

- If a ChannelInputShutdownEvent is fired ByteToMessageDecoder (the super-class of ReplayingDecoder) will call the channelInputClosed(...) method which will pass the incorrect buffer to the decode method of ReplayingDecoder.

Modifications:

Share more code between ByteToMessageDEcoder and ReplayingDecoder and so also support ChannelInputShutdownEvent correctly in ReplayingDecoder

Result:

ChannelInputShutdownEvent is corrrectly handle in ReplayingDecoder as well.

1861461db2 [#4635] Stop decoding if decoder was removed in ReplayingDecoder
We need to check if this handler was removed before continuing with decoding.
If it was removed, it is not safe to continue to operate on the buffer. This was already fixed for ByteToMessageDecoder in 4cdbe39284  but missed for ReplayingDecoder.

Modifications:

Check if decoder was removed after fire messages through the pipeline.

Result:

No illegal buffer access when decoder was removed.

d081851156 Remove ByteBuf.readBytes(int) calls when possible
Motivation:

We use ByteBuf.readBytes(int) in various places where we could either remove it completely or use readSlice(int).retain().

Modifications:

- Remove ByteBuf.readBytes(int) when possible or replace by readSlice(int).retain().

Result:

Faster code.

9aac6dac2e [#4386] ByteToMessage.decodeLast(...) should not call decode(...) if buffer is empty.
Motivation:

If the input buffer is empty we should not have decodeLast(...) call decode(...) as the user may not expect this.

Modifications:

- Not call decode(...) in decodeLast(...) if the input buffer is empty.
- Add testcases.

Result:

decodeLast(...) will not call decode(...) if input buffer is empty.

a2e113b987 Use ByteProcessor.FIND_LF to find end of line
Motivation:

Each call of ByteBuf.getByte(int) method does boundary checking. This can be eliminated by using ByteBuf.forEachByte(ByteProcessor) method and ByteProcessor.FIND_LF processor.

Modifications:

Find end of line with ByteProcessor.FIND_LF

Result:

A little better performance of LineBasedFrameDecoder.

0b1c82b254 Ensure read components can be discarded when COMPOSITE_CUMULATOR is used.
Motivation:

ByteToMessageDecoder must ensure that read components of the CompositeByteBuf can be discard by default when discardSomeReadBytes() is called. This may not be the case before as because of the default maxNumComponents that will cause consolidation.

Modifications:

Ensure we not do any consolidation to actually be abel to discard read components

Result:

Less memory usage and allocations.

b112673554 ByteToMessageDecoder ChannelInputShutdownEvent support
Motivation:
b714297a44 introduced ChannelInputShutdownEvent support for HttpObjectDecoder. However this should have been added to the super class ByteToMessageDecoder, and ByteToMessageDecoder should not propegate a channelInactive event through the pipeline in this case.

Modifications:
- Move the ChannelInputShutdownEvent handling from HttpObjectDecoder to ByteToMessageDecoder
- ByteToMessageDecoder doesn't call ctx.fireChannelInactive() on ChannelInputShutdownEvent

Result:
Half closed events are treated more generically, and don't get translated into a channelInactive pipeline event.

Modifications:

- Correctly handling newlines
- Add unit test that proves the fix.

Result:

No more invalid base64 encoded data.

a0758e7e60 [#4794] Support window size flag by default if ZlibCodecFactory supports it.
Motivation:

If the ZlibCodecFactory can support using a custom window size we should support it by default in the websocket extensions as well.

Modifications:

Detect if a custom window size can be handled by the ZlibCodecFactory and if so enable it by default for PerMessageDeflate*ExtensionHandshaker.

Result:

Support window size flag by default in most installations.

d1ef33b8f4 Change 64 to 63 in Snappy.decodeLiteral
Motivation:

According to https://github.com/google/snappy/blob/master/format_description.txt#L55 , Snappy.decodeLiteral should handle the cases of 60, 61, 62 and 63. However right now it processes 64 instead of 63. I believe it's a typo since `tag >> 2 & 0x3F` must be less than 64.

Modifications:

Use the correct value 63.

Result:

Snappy.decodeLiteral handles the correct case.

3785ca9311 added support for Protobuf codec nano runtime
Motivation:

Netty was missing support for Protobuf nano runtime targeted at
weaker systems such as Android devices.

Modifications:

Added ProtobufDecoderNano and ProtobufDecoderNano
in order to provide support for Nano runtime.

modified ProtobufVarint32FrameDecoder and
ProtobufLengthFieldPrepender in order to remove any
on either Nano or Lite runtime by copying the code
for handling Protobuf varint32 in from Protobuf
library.

modified Licenses and NOTICE in order to reflect the
changes i made.

added Protobuf Nano runtime as optional dependency

Result:

Netty now supports Protobuf Nano runtime.

f7c83c8565 Don't enforce JZlibDecoder on JDK7+, close #4707
Motivation:

`JdkZlibDecoder` is available since Netty 4.0.8 and works with JDK7+.
However, `io.netty.noJdkZlibDecoder` System prop evaluation always defaults to
true, causing Netty to always use JZLib when decompressing on the
client side when the property insn't explictly set to `false`.

Modifications:

Default to `false` instead of `true` when JDK7+.

Result:

JZLib optional as expected on JDK7+.

Motivation:

We should not use Unpooled to allocate buffers for performance reasons.

Modifications:

Allow to pass in ByteBufAllocate which is used to allocate buffers or use the allocate of the src buffer.

Result:

Better performance if the PooledByteBufAllocator is used.

63426fc3ed Prevent adding newline if Base64 buffer encoded ends directly on MAX_LINE_LENGTH
Motivation:

We need to ensure we not add a newline if the Base64 encoded buffer ends directly on the MAX_LINE_LENGTH. If we miss to do so this produce invalid data.
Because of this bug OpenSslServerContext and OpenSslClientContext may fail to load a cert.

Modifications:

- Only add NEW_LINE if we not are on the end of the dst buffer.
- Add unit test

Result:

Correct result in all cases

cfcee5798d Adjustable size of DefaultHeaders array
Motivation:
DefaultHeaders creates an array of size 16 for all headers. This may waste a good deal of memory if applications only have a small number of headers. This memory may be critical when the number of connections grows large.

Modifications:
- Make the size of the array for DefaultHeaders configurable

Result:
Applications can control the size of the DefaultHeaders array and save memory.
