6af56ffe76 HPACK Encoder headerFields improvements
Motivation:
HPACK Encoder has a data structure which is similar to a previous version of DefaultHeaders. Some of the same improvements can be made.

Motivation:
- Enforce the restriction that the Encoder's headerFields length must be a power of two so we can use masking instead of modulo
- Use AsciiString.hashCode which already has optimizations instead of having yet another hash code algorithm in Encoder

Result:
Fixes https://github.com/netty/netty/issues/5357

a7f7d9c8e0 Remove unsafe char[] access in PlatformDependent
Motivation:
PlatformDependent attempts to use reflection to get the underlying char[] (or byte[]) from String objects. This is fragile as if the String implementation does not utilize the full array, and instead uses a subset of the array, this optimization is invalid. OpenJDK6 and some earlier versions of OpenJDK7 String have the capability to use a subsection of the underlying char[].

Modifications:
- PlatformDependent should not attempt to use the underlying array from String (or other data types) via reflection

Result:
PlatformDependent hash code generation for CharSequence does not depend upon specific JDK implementation details.

f0a5ee068f Update dependencies and plugins to latest possible versions.
Motivation:
It is good to have used dependencies and plugins up-to-date to fix any undiscovered bug fixed by the authors.

Modification:
Scanned dependencies and plugins and carefully updated one by one.

Result:
Dependencies and plugins are up-to-date.

c3abb9146e Use shaded dependency on JCTools instead of copy and paste
Motivation:
JCTools supports both non-unsafe, unsafe versions of queues and JDK6 which allows us to shade the library in netty-common allowing it to stay "zero dependency".

Modifications:
- Remove copy paste JCTools code and shade the library (dependencies that are shaded should be removed from the <dependencies> section of the generated POM).
- Remove usage of OneTimeTask and remove it all together.

Result:
Less code to maintain and easier to update JCTools and less GC pressure as the queue implementation nt creates so much garbage

dc816e9807 Ensure we null out cumulation buffer before fire through the pipeline in handlerRemoved(...)
Motivation:

We should ensure we null out the cumulation buffer before we fire it through the pipleine in handlerRemoved(...) as in theory it could be possible that another method is triggered as result of the fireChannelRead(...) or fireChannelReadComplete() that will try to access the cumulation.

Modifications:

Null out cumulation buffer early in handlerRemoved(...)

Result:

No possible to access the cumulation buffer that was already handed over.

af7b0a04a0 Fix DefaultHeaders.toString() for keys with multiple values.
Motivation:

For example,

DefaultHttp2Headers headers = new DefaultHttp2Headers();
headers.add("key1", "value1");
headers.add("key1", "value2");
headers.add("key1", "value3");
headers.add("key2", "value4");

produces:

DefaultHttp2Headers[key1: value1key1: value2key1: value3, key2: value4]

while correctly it should be

DefaultHttp2Headers[key1: value1, key1: value2, key1: value3, key2: value4]

Modifications:

Change the toString() method to produce the beforementioned output.

Result:

toString() format is correct also for keys with multiple values.

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.

65b3470456 [#4793] Correctly add newlines when encode base64
Motivation:

We not correctly added newlines if the src data needed to be padded. This regression was introduced by '63426fc3ed083513c07a58b45381f5c10dd47061'

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.
