Motivation:
While working on #6087 some buffer leaks showed up.
Modifications:
Correctly release buffers.
Result:
No more buffer leaks in memcache and stomp codec tests.
Motivation:
the build doesnt seem to enforce this, so they piled up
Modifications:
removed unused import lines
Result:
less unused imports

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
Motivation:
Some codecs should be considered unstable as these are relative new. For this purpose we should introduce an annotation which these codecs should us to be marked as unstable in terms of API.
Modifications:
- Add UnstableApi annotation and use it on codecs that are not stable
- Move http2.hpack to http2.internal.hpack as it is internal.
Result:
Better document unstable APIs.
Motivation:
It's better to have some tests for FullMemcacheMessageRequest and FullMemcacheMessageResponse to avoid regression like #5197.
Modifications:
Add tests for FullMemcacheMessageRequest and FullMemcacheMessageResponse.
Result:
There are some basic tests for FullMemcacheMessageRequest and FullMemcacheMessageResponse.
Motivation:
This reverts commit 3405aee2ab. This commit introduces a bug and the encoder no longer encodes FullMemcacheMessage objects correctly.
Modifications:
- Revert commit
Result:
Fixes https://github.com/netty/netty/issues/5197
Motivation:
People need to set all length fields manually when creating a memcache message and it's error prone. See #2736 for more dicussion.
Modifications:
This patch adds the logic to update the keyLength, extrasLength and totalBodyLength when key, extras or content is set.
Result:
The length fields of memcache messages will be updated automatically.
Motivation:
The key can be ByteBuf to avoid converting between ByteBuf and String. See #3689.
Modifications:
Replace the type of key with ByteBuf.
Result:
The type of key becomes ByteBuf.
Motivation:
Some duplicated methods in message types of codec-memcache can be cleaned using AbstractReferenceCounted.
Modifications:
Use AbstractReferenceCounted to avoid duplicated methods.
Result:
Duplicated methods are cleaned.
Motivation:
BinaryMemcacheObjectAggregator doesn't retain ByteBuf `extras`. So `io.netty.util.IllegalReferenceCountException: refCnt: 0, decrement: 1` will be thrown when aggregating a message containing `extras`. See the unit test for an example.
Modifications:
`ratain` extras to fix IllegalReferenceCountException.
Result:
`extras` is retained.
