27ff15319c Reduce memory allocations in StompSubframeDecoder.readHeaders
Motivation:
When decoding stomp frames a lot of unnecessary character arrays are created when parsing headers.
For every header, an array is created to read the line into and then more when splitting the line at the colon.

Modifications:
Parse key and value of a header while reading the line instead of afterwards.
Reuse a single AppendableCharSequence.
Reduce initial size of AppendableCharSequence when reading the command as it is expected to be short.

Result:
Allocations when parsing stomp frames have dropped significantly.

e8540c2b7a Adding stable JDK9 module names that follow reverse-DNS style
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html

When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.

Modification:

The POM-s are configured to put the correct module names to the manifest.

Result:

Fixes #7218.

4875a2aad4 Immediate caching the strings wrapped to AsciiString
Motivation:
The `AsciiString#toString` method calculate string value and cache it into field. If an `AsciiString` created from the `String` value, we can avoid rebuilding strings if we cache them immediately when creating `AsciiString`. It would be useful for constants strings, which already stored in the JVMs string table, or in cases where an unavoidable `#toString `method call is assumed.

Modifications:
- Add new static method `AsciiString#cache(String)` which save string value into cache field.
- Apply a "benign" data race in the `#hashCode` and `#toString` methods.

Result:
Less memory usage in some `AsciiString` use cases.

ba3616da3e Apply appropriate methods for writing CharSequence into ByteBuf
Motivation:

1. `ByteBuf` contains methods to writing `CharSequence` which optimized for UTF-8 and ASCII encodings. We can also apply optimization for ISO-8859-1.
2. In many places appropriate methods are not used.

Modifications:

1. Apply optimization for ISO-8859-1 encoding in the `ByteBuf#setCharSequence` realizations.
2. Apply appropriate methods for writing `CharSequences` into buffers.

Result:

Reduce overhead from string-to-bytes conversion.

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

19658e9cd8 HTTP/2 Headers Type Updates
Motivation:
The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-8.1.2) indicates that header names consist of ASCII characters. We currently use ByteString to represent HTTP/2 header names. The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-10.3) also eludes to header values inheriting the same validity characteristics as HTTP/1.x. Using AsciiString for the value type of HTTP/2 headers would allow for re-use of predefined HTTP/1.x values, and make comparisons more intuitive. The Headers<T> interface could also be expanded to allow for easier use of header types which do not have the same Key and Value type.

Motivation:
- Change Headers<T> to Headers<K, V>
- Change Http2Headers<ByteString> to Http2Headers<CharSequence, CharSequence>
- Remove ByteString. Having AsciiString extend ByteString complicates equality comparisons when the hash code algorithm is no longer shared.

Result:
Http2Header types are more representative of the HTTP/2 RFC, and relationship between HTTP/2 header name/values more directly relates to HTTP/1.x header names/values.

2adf6e5358 Better parsing for STOMP body with no length.
Motivation:

The STOMP decoder used to fail when parsing a frame with no content-length
and a body split across multiple packets.

Modifications:

Support contentLength of -1 (indicating indeterminate length) and added a
check to getContentLength.  Moved the NUL byte searching from the
readHeaders() method out to the main decoder loop.

Result:

A STOMP frame can be properly parsed even if it's missing the
content-length header and the NUL byte is in a later packet.

7adc1f9eb4 STOMP Headers Name Comparator
Motivation:
The HashingStrategy for DefaultStompHeaders was using the java .equals() method which would fail to compare String, AsciiString, and other CharSequence objects as equal.

Modification:
- Use AsciiString.CASE_SENSITIVE_HASHER for DefaultStompHeaders

Result:
DefaultStompHeaders work with all CharSequence objects.

a7135e8677 HttpObjectAggregator doesn't check content-length header
Motivation:
The HttpObjectAggregator always responds with a 100-continue response. It should check the Content-Length header to see if the content length is OK, and if not responds with a 417.

Modifications:
- HttpObjectAggregator checks the Content-Length header in the case of a 100-continue.

Result:
HttpObjectAggregator responds with 417 if content is known to be too big.

ba6ce5449e Headers Performance Boost and Interface Simplification
Motivation:
A degradation in performance has been observed from the 4.0 branch as documented in https://github.com/netty/netty/issues/3962.

Modifications:
- Simplify Headers class hierarchy.
- Restore the DefaultHeaders to be based upon DefaultHttpHeaders from 4.0.
- Make various other modifications that are causing hot spots.

Result:
Performance is now on par with 4.0.

6fd0a0c55f Faster and more memory efficient headers for HTTP, HTTP/2, STOMP and SPYD. Fixes #3600
Motivation:

We noticed that the headers implementation in Netty for HTTP/2 uses quite a lot of memory
and that also at least the performance of randomly accessing a header is quite poor. The main
concern however was memory usage, as profiling has shown that a DefaultHttp2Headers
not only use a lot of memory it also wastes a lot due to the underlying hashmaps having
to be resized potentially several times as new headers are being inserted.

This is tracked as issue #3600.

Modifications:
We redesigned the DefaultHeaders to simply take a Map object in its constructor and
reimplemented the class using only the Map primitives. That way the implementation
is very concise and hopefully easy to understand and it allows each concrete headers
implementation to provide its own map or to even use a different headers implementation
for processing requests and writing responses i.e. incoming headers need to provide
fast random access while outgoing headers need fast insertion and fast iteration. The
new implementation can support this with hardly any code changes. It also comes
with the advantage that if the Netty project decides to add a third party collections library
as a dependency, one can simply plug in one of those very fast and memory efficient map
implementations and get faster and smaller headers for free.

For now, we are using the JDK's TreeMap for HTTP and HTTP/2 default headers.

Result:

- Significantly fewer lines of code in the implementation. While the total commit is still
  roughly 400 lines less, the actual implementation is a lot less. I just added some more
  tests and microbenchmarks.

- Overall performance is up. The current implementation should be significantly faster
  for insertion and retrieval. However, it is slower when it comes to iteration. There is simply
  no way a TreeMap can have the same iteration performance as a linked list (as used in the
  current headers implementation). That's totally fine though, because when looking at the
  benchmark results @ejona86 pointed out that the performance of the headers is completely
  dominated by insertion, that is insertion is so significantly faster in the new implementation
  that it does make up for several times the iteration speed. You can't iterate what you haven't
  inserted. I am demonstrating that in this spreadsheet [1]. (Actually, iteration performance is
  only down for HTTP, it's significantly improved for HTTP/2).

- Memory is down. The implementation with TreeMap uses on avg ~30% less memory. It also does not
  produce any garbage while being resized. In load tests for GRPC we have seen a memory reduction
  of up to 1.2KB per RPC. I summarized the memory improvements in this spreadsheet [1]. The data
  was generated by [2] using JOL.

- While it was my original intend to only improve the memory usage for HTTP/2, it should be similarly
  improved for HTTP, SPDY and STOMP as they all share a common implementation.

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.

8206cc6e14 Headers set/add/contains timeMillis methods
Motivation:
The new Headers interface contains methods to getTimeMillis but no add/set/contains variants.  These should be added for consistency.

Modifications:
- Add three new methods: addTimeMillis, setTimeMillis, containsTimeMillis to the Headers interface.
- Add a new method to the Headers.ValueConverter interface: T convertTimeMillis(long)
- Bring these new interfaces up the class hierarchy

Result:
All Headers classes have setters/getters for timeMillis.

b83df4c6b3 Fix NPE problems
Motivation:

Now Netty has a few problems with null values.

Modifications:

- Check HAProxyProxiedProtocol in HAProxyMessage constructor and throw NPE if it is null.
If HAProxyProxiedProtocol is null we will set AddressFamily as null. So we will get NPE inside checkAddress(String, AddressFamily) and it won't be easy to understand why addrFamily is null.
- Check File in DiskFileUpload.toString().
If File is null we will get NPE when calling toString() method.
- Check Result<String> in MqttDecoder.decodeConnectionPayload(...).
If !mqttConnectVariableHeader.isWillFlag() || !mqttConnectVariableHeader.hasUserName() || !mqttConnectVariableHeader.hasPassword() we will get NPE when we will try to create new instance of MqttConnectPayload.
- Check Unsafe before calling unsafe.getClass() in PlatformDependent0 static block.
- Removed unnecessary null check in WebSocket08FrameEncoder.encode(...).
Because msg.content() can not return null.
- Removed unnecessary null check in DefaultStompFrame(StompCommand) constructor.
Because we have this check in the super class.
- Removed unnecessary null checks in ConcurrentHashMapV8.removeTreeNode(TreeNode<K,V>).
- Removed unnecessary null check in OioDatagramChannel.doReadMessages(List<Object>).
Because tmpPacket.getSocketAddress() always returns new SocketAddress instance.
- Removed unnecessary null check in OioServerSocketChannel.doReadMessages(List<Object>).
Because socket.accept() always returns new Socket instance.
- Pass Unpooled.buffer(0) instead of null inside CloseWebSocketFrame(boolean, int) constructor.
If we will pass null we will get NPE in super class constructor.
- Added throw new IllegalStateException in GlobalEventExecutor.awaitInactivity(long, TimeUnit) if it will be called before GlobalEventExecutor.execute(Runnable).
Because now we will get NPE. IllegalStateException will be better in this case.
- Fixed null check in OpenSslServerContext.setTicketKeys(byte[]).
Now we throw new NPE if byte[] is not null.

Result:

Added new null checks when it is necessary, removed unnecessary null checks and fixed some NPE problems.

ad1389be9d Small performance improvements
Modifications:

- 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.
