92bfeeca1b No need to release lock and acquire again when allocate normal size.
Motiviation:

When tried to allocate tiny and small sized and failed to serve these out of the PoolSubPage we exit the synchronization
block just to enter it again when call allocateNormal(...).

Modification:

Not exit the synchronized block until allocateNormal(...) is done.

Result:

Better performance.

79c17cf1fd ByteBufUtil use IndexOfProcessor to find occurrence.
Motivation:
The way of firstIndexOf and lastIndexOf iterating the ByteBuf is similar to forEachByte and forEachByteDesc, but have many range checks.
Modifications:
Use forEachByte and a IndexOfProcessor to find occurrence.
Result:
eliminate range checks

f812180c2d ByteString arrayOffset method
Motivation:
The ByteString class currently assumes the underlying array will be a complete representation of data. This is limiting as it does not allow a subsection of another array to be used. The forces copy operations to take place to compensate for the lack of API support.

Modifications:
- add arrayOffset method to ByteString
- modify all ByteString and AsciiString methods that loop over or index into the underlying array to use this offset
- update all code that uses ByteString.array to ensure it accounts for the offset
- add unit tests to test the implementation respects the offset

Result:
ByteString and AsciiString can represent a sub region of a byte[].

8b1f247a1a [#3623] CompositeByteBuf.iterator() should return optimized Iterable
Motivation:

CompositeByteBuf.iterator() currently creates a new ArrayList and fill it with the ByteBufs, which is more expensive then it needs to be.

Modifications:

- Use special Iterator implementation

Result:

Less overhead when calling iterator()

9a7a85dbe5 ByteString introduced as AsciiString super class
Motivation:
The usage and code within AsciiString has exceeded the original design scope for this class. Its usage as a binary string is confusing and on the verge of violating interface assumptions in some spots.

Modifications:
- ByteString will be created as a base class to AsciiString. All of the generic byte handling processing will live in ByteString and all the special character encoding will live in AsciiString.

Results:
The AsciiString interface will be clarified. Users of AsciiString can now be clear of the limitations the class imposes while users of the ByteString class don't have to live with those limitations.

4d02c3a040 [#2925] Bug fix for NormalMemoryRegionCache overbooked for PoolThreadCache
Motivation:

When create NormalMemoryRegionCache for PoolThreadCache, we overbooked
cache array size. This means unnecessary overhead for thread local cache
as we will create multi cache enties for each element in cache array.

Modifications:

change:
int arraySize = Math.max(1, max / area.pageSize);
to:
int arraySize = Math.max(1, log2(max / area.pageSize) + 1);

Result:

Now arraySize won't introduce unnecessary overhead.

7094c7b797 Dereference when calling PooledByteBuf.deallocate()
Motivation:

We missed to dereference the chunk and tmpNioBuf when calling deallocate(). This means the GC can not collect these as we still hold a reference while have the PooledByteBuf in the recycler stack.

Modifications:

Dereference chunk and tmpNioBuf.

Result:

GC can collect things.

3e42292d8b Change PoolThreadCache to use LIFO for better cache performance
Motiviation:

At the moment we use FIFO for the PoolThreadCache which is sub-optimal as this may reduce the changes to have the cached memory actual still in the cpu-cache.

Modification:

- Change to use LIFO as this increase the chance to be able to serve buffers from the cpu-cache

Results:

Faster allocation out of the ThreadLocal cache.

0d3a6e0511 HTTP/2 Decoder reduce preface conditional checks
Motivation:
The DefaultHttp2ConnectionDecoder class is calling verifyPrefaceReceived() for almost every frame event at all times.
The Http2ConnectionHandler class is calling readClientPrefaceString() on every decode event.

Modifications:
- DefaultHttp2ConnectionDecoder should not have to continuously call verifyPrefaceReceived() because it transitions boolean state 1 time for each connection.
- Http2ConnectionHandler should not have to continuously call readClientPrefaceString() because it transitions boolean state 1 time for each connection.

Result:
- Less conditional checks for the mainstream usage of the connection.

4500adb6e0 Updates the javadoc of Unpooled to remove mention to methods it does not provide
Motivation:

`Unpooled` javadoc's mentioned the generation of hex dump and swapping an integer's byte order,
which are actually provided by `ByteBufUtil`.

Modifications:

 Sentence moved to `ByteBufUtil` javadoc.

Result:

`Unpooled` javadoc is correct.

41fd857a7c Ensure CompositeByteBuf.addComponent* handles buffer in consistent way and not causes leaks
Motivation:

At the moment we have two problems:
 - CompositeByteBuf.addComponent(...) will not add the supplied buffer to the CompositeByteBuf if its empty, which means it will not be released on CompositeByteBuf.release() call. This is a problem as a user will expect everything added will be released (the user not know we not added it).
 - CompositeByteBuf.addComponents(...) will either add no buffers if none is readable and so has the same problem as addComponent(...) or directly release the ByteBuf if at least one ByteBuf is readable. Again this gives inconsistent handling and may lead to memory leaks.

Modifications:

 - Always add the buffer to the CompositeByteBuf and so release it on release call.

Result:

Consistent handling and no buffer leaks.

155c0e2f36 Implement internal memory access methods of CompositeByteBuf correctly
Motivation:

When a CompositeByteBuf is empty (i.e. has no component), its internal
memory access operations do not always behave as expected.

Modifications:

Check if the nunmber of components is zero. If so, return an empty
array or an empty NIO buffer, etc.

Result:

More robustness

fe796fc8ab Provide helper methods in ByteBufUtil to write UTF-8/ASCII CharSequences. Related to [#909]
Motivation:

We expose no methods in ByteBuf to directly write a CharSequence into it. This leads to have the user either convert the CharSequence first to a byte array or use CharsetEncoder. Both cases have some overheads and we can do a lot better for well known Charsets like UTF-8 and ASCII.

Modifications:

Add ByteBufUtil.writeAscii(...) and ByteBufUtil.writeUtf8(...) which can do the task in an optimized way. This is especially true if the passed in ByteBuf extends AbstractByteBuf which is true for all of our implementations which not wrap another ByteBuf.

Result:

Writing an ASCII and UTF-8 CharSequence into a AbstractByteBuf is a lot faster then what the user could do by himself as we can make use of some package private methods and so eliminate reference and range checks. When the Charseq is not ASCII or UTF-8 we can still do a very good job and are on par in most of the cases with what the user would do.

The following benchmark shows the improvements:

66294892a0 CompositeByteBuf.nioBuffers(...) must not return an empty ByteBuffer array
Motivation:

CompositeByteBuf.nioBuffers(...) returns an empty ByteBuffer array if the specified length is 0. This is not consistent with other ByteBuf implementations which return an ByteBuffer array of size 1 with an empty ByteBuffer included.

Modifications:

Make CompositeByteBuf.nioBuffers(...) consistent with other ByteBuf implementations.

Result:

Consistent and correct behaviour of nioBufffers(...)

a69a39c849 Always return SliceByteBuf on slice(...) to eliminate possible leak
Motivation:

When calling slice(...) on a ByteBuf the returned ByteBuf should be the slice of a ByteBuf and shares it's reference count. This is important as it is perfect legal to use buf.slice(...).release() and have both, the slice and the original ByteBuf released. At the moment this is only the case if the requested slice size is > 0. This makes the behavior inconsistent and so may lead to a memory leak.

Modifications:

- Never return Unpooled.EMPTY_BUFFER when calling slice(...).
- Adding test case for buffer.slice(...).release() and buffer.duplicate(...).release()

Result:

Consistent behaviour and so no more leaks possible.

182c91f06c Ensure buffer is not released when call array() / memoryAddress()
Motivation:

Before we missed to check if a buffer was released before we return the backing byte array or memoryaddress. This could lead to JVM crashes when someone tried various bulk operations on the Unsafe*ByteBuf implementations.

Modifications:

Always check if the buffer is released before all to return the byte array and memoryaddress.

Result:

No more JVM crashes because of released buffers when doing bulk operations on Unsafe*ByteBuf implementations.

35db3c6710 Small performance improvements
Motivation:

Found performance issues via FindBugs and PMD.

Modifications:

- Removed unnecessary boxing/unboxing operations in DefaultTextHeaders.convertToInt(CharSequence) and DefaultTextHeaders.convertToLong(CharSequence). A boxed primitive is created from a string, just to extract the unboxed primitive value.
- Added a static modifier for DefaultHttp2Connection.ParentChangedEvent class. This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.
- Added a static compiled Pattern to avoid compile it each time it is used when we need to replace some part of authority.
- Improved using of StringBuilders.

Result:

Performance improvements.

48f1398869 Disable caching of PooledByteBuf for different threads.
Motivation:

We introduced a PoolThreadCache which is used in our PooledByteBufAllocator to reduce the synchronization overhead on PoolArenas when allocate / deallocate PooledByteBuf instances. This cache is used for both the allocation path and deallocation path by:
  - Look for cached memory in the PoolThreadCache for the Thread that tries to allocate a new PooledByteBuf and if one is found return it.
  - Add the memory that is used by a PooledByteBuf to the PoolThreadCache of the Thread that release the PooledByteBuf

This works out very well when all allocation / deallocation is done in the EventLoop as the EventLoop will be used for read and write. On the otherside this can lead to surprising side-effects if the user allocate from outside the EventLoop and and pass the ByteBuf over for writing. The problem here is that the memory will be added to the PoolThreadCache that did the actual write on the underlying transport and not on the Thread that previously allocated the buffer.

Modifications:

Don't cache if different Threads are used for allocating/deallocating

Result:

Less confusing behavior for users that allocate PooledByteBufs from outside the EventLoop.

858de5699b [#2924] Correctly update head in MemoryRegionCache.trim()
Motivation:
When MemoryRegionCache.trim() is called, some unused cache entries will be freed (started from head). However, in MeoryRegionCache.trim() the head is not updated, which make entry list's head point to an entry whose chunk is null now and following allocate of MeoryRegionCache will return false immediately.

In other word, cache is no longer usable once trim happen.

Modifications:

Update head to correct idx after free entries in trim().

Result:

MemoryRegionCache behaves correctly even after calling trim().

Motivation:

Modifications:

Add test-case which shows that all is working like expected

Result:

Test-case added which shows everything is ok.

0dc6a8dccf Use heap buffers for Unpooled.copiedBuffer()
Related issue: #2028

Motivation:

Some copiedBuffer() methods in Unpooled allocated a direct buffer.  An
allocation of a direct buffer is an expensive operation, and thus should
be avoided for unpooled buffers.

Modifications:

- Use heap buffers in all copiedBuffer() methods

Result:

Unpooled.copiedBuffers() are less expensive now.

 - 997d8c32d2
 - e282e504f1
 - 5e5d1a58fd
 - 8ee3575e72
 - d6f0d12a86
 - 16e50765d1
 - 3f3e66c31a

Result:
 - Less memory usage by ChannelOutboundBuffer
 - Same code as in 4.0 branch
 - Make it possible to use ChannelOutboundBuffer with Channel implementation that not extends AbstractChannel

- Added a static modifier for CompositeByteBuf.Component.
This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.
- Removed unnecessary boxing/unboxing operations in HttpResponseDecoder, RtspResponseDecoder, PerMessageDeflateClientExtensionHandshaker and PerMessageDeflateServerExtensionHandshaker
A boxed primitive is created from a String, just to extract the unboxed primitive value.
- Removed unnecessary 3 times calculations in DiskAttribute.addContent(...).
- Removed unnecessary checks if file exists before call mkdirs() in NativeLibraryLoader and PlatformDependent.
Because the method mkdirs() has this check inside.
- Removed unnecessary `instanceof AsciiString` check in StompSubframeAggregator.contentLength(StompHeadersSubframe) and StompSubframeDecoder.getContentLength(StompHeaders, long).
Because StompHeaders.get(CharSequence) always returns java.lang.String.

ac8ac59148 [#2642] CompositeByteBuf.deallocate memory/GC improvement
Motivation:

CompositeByteBuf.deallocate generates unnecessary GC pressure when using the 'foreach' loop, as a 'foreach' loop creates an iterator when looping.

fbf1bdbef1 Fix the build timeout when 'leak' profile is active
Motivation:

AbstractByteBufTest.testInternalBuffer() uses writeByte() operations to
populate the sample data.  Usually, this isn't a problem, but it starts
to take a lot of time when the resource leak detection level gets
higher.

In our CI machine, testInternalBuffer() takes more than 30 minutes,
causing the build timeout when the 'leak' profile is active (paranoid
level resource detection.)

Modification:

Populate the sample data using ThreadLocalRandom.nextBytes() instead of
using millions of writeByte() operations.

Result:

Test runs much faster when leak detection level is high.

9594a81b95 [#2622] Correctly check reference count before try to work on the underlying memory
Motivation:

Because of how we use reference counting we need to check for the reference count before each operation that touches the underlying memory. This is especially true as we use sun.misc.Cleaner.clean() to release the memory ASAP when possible. Because of this the user may cause a SEGFAULT if an operation is called that tries to access the backing memory after it was released.

Modification:

Correctly check the reference count on all methods that access the underlying memory or expose it via a ByteBuffer.

Result:

Safer usage of ByteBuf

c0462c0c3b Optimize PoolChunk
- Using short[] for memoryMap did not improve performance. Reverting
  back to the original dual-byte[] structure in favor of simplicity.
- Optimize allocateRun() which yields small performence improvement
- Use local variable when member fields are accessed more than once

69a6ad940a Improve the allocation algorithm in PoolChunk
Motivation:

Depth-first search is not always efficient for buddy allocation.

Modification:

Employ a new faster search algorithm with different memoryMap layout.

Result:

With thread-local cache disabled, we see a lot of performance
improvment, especially when the size of the allocation is as small as
the page size, which had the largest search space previously.
