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.

7aca99f986 DefaultHttpHeader.names().toArray(...) may throw ArrayStoreException
Motivation:

DefaultHttpHeader.names() exposes HTTP header names as a Set<String>. Converting the resulting set to an array using toArray(String[]) throws an exception: java.lang.ArrayStoreException: io.netty.util.AsciiString.

Modifications:

- Remove our custom implementation of toArray(...) (and others) by just extending AbstractCollection.
- Add unit test

Result:

Fixes [#7428].

e420f857fa Optimize DefaultHeaders#toString and implement HttpHeaders#toString
Motivation:

For debugging/logging purpose, it would be convenient to have
HttpHeaders#toString implemented.

DefaultHeaders does implement toString be the implementation is suboptimal and allocates a Set for the names and Lists for values.

Modification:

* Introduce HeadersUtil#toString that provides a convenient optimized helper to implement toString for various headers implementations
* Have DefaultHeaders#toString and HttpHeaders#toString delegate their toString implementation to HeadersUtil

Result:

Convenient HttpHeaders#toString. Optimized DefaultHeaders#toString.

93130b172a HttpObjectEncoder and MessageAggregator EMPTY_BUFFER usage
Motivation:
HttpObjectEncoder and MessageAggregator treat buffers that are not readable special. If a buffer is not readable, then an EMPTY_BUFFER is written and the actual buffer is ignored. If the buffer has already been released then this will not be correct as the promise will be completed, but in reality the original content shouldn't have resulted in any write because it was invalid.

Modifications:
- HttpObjectEncoder should retain/write the original buffer instead of using EMPTY_BUFFER
- MessageAggregator should retain/write the original ByteBufHolder instead of using EMPTY_BUFFER

Result:
Invalid write operations which happen to not be readable correctly reflect failed status in the promise, and do not result in any writes to the channel.

50a067a8f7 Make methods 'static' where it possible
Motivation:

Even if it's a super micro-optimization (most JVM could optimize such
 cases in runtime), in theory (and according to some perf tests) it
 may help a bit. It also makes a code more clear and allows you to
 access such methods in the test scope directly, without instance of
 the class.

Modifications:

Add 'static' modifier for all methods, where it possible. Mostly in
test scope.

Result:

Cleaner code with proper 'static' modifiers.

558097449c Add missed 'serialVersionUID' field for Serializable classes
Motivation:

Without a 'serialVersionUID' field, any change to a class will make
previously serialized versions unreadable.

Modifications:

Add missed 'serialVersionUID' field for all Serializable
classes.

Result:

Proper deserialization of previously serialized objects.

3fe1f71511 Do not treat errors as decoder exception (redux)
Motivation: Today when Netty encounters a general error while decoding
it treats this as a decoder exception. However, for fatal causes this
should not be treated as such, instead the fatal error should be carried
up the stack without the callee having to unwind causes. This was
probably done for byte to byte message decoder but is now done for all
decoders.

Modifications: Instead of translating any error to a decoder exception,
we let those unwind out the stack (note that finally blocks still
execute) except in places where an event needs to fire where we fire
with the error instead of wrapping in a decoder exception.

Result: Fatal errors will not be treated as innocent decoder exceptions.

80b8a91b70 Use offset finding eol avoid repeated scaning.
Motivation:

A large frame will be componsed by many packages. Every time the package
arrived, findEndOfLine will be called from the start of the buffer. It
will cause the complexity of reading frame equal to  O(n^2). This can be
eliminated by using a offset to mark the last scan position, when new
package arrived, just find the delimter from the mark. The complexity
will be O(n).

Modification:

Add a offset to mark the last scan position.

Result:

Better performance for read large frame.

44bb3b6f3a DefaultHeaders value iterator
Motivation:
The Headers interface supports an interface to get all the headers values corresponding to a particular name. This API returns a List which requires intermediate storage and increases GC pressure.

Modifications:
- Add a method which returns an iterator over all the values for a specific name

Result:
Ability to iterator over values for a specific name with no intermediate collection.

6780183a89 Makes LengthFieldBasedFrameDecoder::decode inlineable
Motivation:

The decode method is too large to be inlined with default compiler settings, hence the uncommon paths need to be packed and moved away form the common one.

Modifications:

The uncommon paths of the decode call (eg failures with thrown exceptions) are packed and moved in private methods in order to reduce the size of the common one
and let it being inlined.

Result:

The decode method is being inlined if the stack depth allows it.

03d89c2222 Use Constructor for reflective class instantiation.
Motivation:
Calling `newInstance()` on a Class object can bypass compile time
checked Exception propagation.  This is noted in Java Puzzlers,
as well as in ErrorProne:
http://errorprone.info/bugpattern/ClassNewInstance

Modifications:
Use the niladic constructor to create a new instance.

Result:
Compile time safety for checked exceptions

db4781282f Handle partially decoded elements while streaming Json array
Motivation:

'insideString' and 'openBraces' need a proper handling when streaming
Json array over multiple writes and an element decoding was started but
not completed.
Related to #6969

Modifications:

If the idx is reset:
- 'insideString' has to be reset to 'false' in order to indicate that
  array element will be decoded from the beginning
- 'openBraces' has to be reset to '1' to indicate that Json array
  decoding is in progress.

Result:
Json array is properly decoded when in streaming mode

d63bb4811e Only call ctx.fireChannelReadComplete() if ByteToMessageDecoder decoded at least one message.
Motivation:

Its wasteful and also confusing that channelReadComplete() is called even if there was no message forwarded to the next handler.

Modifications:

- Only call ctx.fireChannelReadComplete() if at least one message was decoded
- Add unit test

Result:

Less confusing behavior. Fixes [#4312].

6ab9c177ac Fix hash function and hash table size in Snappy
Motivation:

1. Hash function in the Snappy encoding is wrong probably: used '+' instead of '*'. See the reference implementation [1].
2. Size of the hash table is calculated, but not applied.

Modifications:

1. Fix hash function: replace addition by multiplication.
2. Allocate hash table with calculated size.
3. Use an `Integer.numberOfLeadingZeros` trick for calculate log2.
4. Release buffers in tests.

Result:

1. Better compression. In the test `encodeAndDecodeLongTextUsesCopy` now compressed size is 175 instead of 180 before this change.
2. No redundant allocations for hash table.
3. A bit faster the calc of shift (less an expensive math operations).

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.

14ea69cdc1 NullPointerException in Lz4FrameEncoder
Motivation:
Lz4FrameEncoder maintains internal state, but the life cycle of the buffer is not consistently managed. The buffer is allocated in handlerAdded but freed in close, but the buffer can still be used until handlerRemoved is called.

Modifications:
- Move the cleanup of the buffer from close to handlerRemoved
- Explicitly throw an EncoderException from Lz4FrameEncoder if the encode operation has finished and there isn't enough space to write data

Result:
No more NPE in Lz4FrameEncoder on the buffer.

e06cb82c4c JdkZlibDecoder and JZlibDecoder consistency
Motivation:
JdkZlibDecoder will allocate a new buffer when the previous buffer is filled with inflated data, but JZlibDecoder will attempt to use the same buffer by resizing. This leads to inconsistent results when these two decoders that are intended to be functionality equivalent.

Modifications:
- JdkZlibDecoder should attempt to resize and reuse the existing buffer instead of creating multiple buffers

Result:

ce2ce9d7a4 ByteToMessageDecoder#handlerRemoved may release cumulation buffer prematurely
Motivation:
ByteToMessageDecoder#handlerRemoved will immediately release the cumulation buffer, but it is possible that a child class may still be using this buffer, and therefore use a dereferenced buffer.

Modifications:
- ByteToMessageDecoder#handlerRemoved and ByteToMessageDecoder#decode should coordinate to avoid the case where a child class is using the cumulation buffer but ByteToMessageDecoder releases that buffer.

Result:
Child classes of ByteToMessageDecoder are less likely to reference a released buffer.

38b054c65c Correctly handle read-only ByteBuf in ByteToMessageDecoder
Motivation:

If a read-only ByteBuf is passed to the ByteToMessageDecoder.channelRead(...) method we need to make a copy of it once we try to merge buffers for cumulation. This usually is not the case but can for example happen if the local transport is used. This was the cause of the leak report we sometimes saw during the codec-http2 tests, as we are using the local transport and write a read-only buffer. This buffer will then be passed to the peer channel and fired through the pipeline and so end up as the cumulation buffer in the ByteToMessageDecoder. Once the next fragement is received we tried to merge these and failed with a ReadOnlyBufferException which then produced a leak.

Modifications:

Ensure we copy the buffer if its read-only.

Result:

No more exceptions and so leak when a read-only buffer is passed to ByteToMessageDecoder.channelRead(...)

476d2aea76 Adding method to assert XML decoder framing works
Motivation:

In an effort to better understand how the XmlFrameDecoder works, I consulted the tests to find a method that would reframe the inputs as per the Javadocs for that class. I couldn't find any methods that seemed to be doing it, so I wanted to add one to reinforce my understanding.

Modification:

Add a new test method to XmlFrameDecoder to assert that the reframing works as described.

Result:

New test method is added to XmlFrameDecoder

77e65fe6bb Base64 reduce byte manipulation operations
Motivation:
Base64#decode4to3 generally calculates an int value where the contents of the decodabet straddle bytes, and then uses a byte shifting or a full byte swapping operation to get the resulting contents. We can directly calculate the contents and avoid any intermediate int values and full byte swap operations. This will reduce the number of operations required during the decode operation.

Modifications:
- remove the intermediate int in the Base64#decond4to3 method.
- manually do the byte shifting since we are already doing bit/byte manipulations here anyways.

Result:
Base64#decode4to3 requires less operations to compute the end result.

7feb92959e Improve performance of Base64.decode and encode methods.
Motivation:

The decode and encode method uses getByte(...) and setByte(...) in loops which can be very expensive because of bounds / reference-count checking. Beside this it also slows-down a lot when paranoid leak-detection is enabled as it will track each access.

Modifications:

- Pack bytes into int / short and so reduce operations on the ByteBuf
- Use ByteProcessor to reduce getByte calls.

Result:

Better performance in general. Also when you run the build with -Pleak the handler module will build in 1/4 of the time it took before.

3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
Motivation:

Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.

This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.

Modifications:

I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.

Result:

A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.

3ea807e375 Flush LZ4FrameEncoder buffer when channel flush() is received.
Motivation:

LZ4FrameEncoder maintains an internal buffer of incoming data compress, and only writes out compressed data when a size threshold is reached. LZ4FrameEncoder does not override the flush() method, and thus the only way to flush data down the pipeline is via more data or close the channel.

Modifications:

Override the flush() function to flush on demand. Also overrode the allocateBuffer() function so we can more accurately size the output buffer (instead of needing to potatntially realloc via buffer.ensureWritable()).

Result:

Implementation works as described.

ba95c401a7 Misc clean up
Motivation:
IntelliJ issues several warnings.

Modifications:

* `ClientCookieDecoder` and `ServerCookieDecoder`:
  * `nameEnd`, `valueBegin` and `valueEnd` don't need to be initialized
  * `keyValLoop` loop doesn't been to be labelled, as it's the most inner one (same thing for labelled breaks)
  * Remove `if (i != headerLen)` as condition is always true
* `ClientCookieEncoder` javadoc still mention old logic
* `DefaultCookie`, `ServerCookieEncoder` and `DefaultHttpHeaders` use ternary ops that can be turned into simple boolean ones
* `DefaultHeaders` uses a for(int) loop over an array. It can be turned into a foreach one as javac doesn't allocate an iterator to iterate over arrays
* `DefaultHttp2Headers` and `AbstractByteBuf` `equal` can be turned into a single boolean statement
Result:

Cleaner code

f755e58463 Clean up following #6016
Motivation:

* DefaultHeaders from netty-codec has some duplicated logic for header date parsing
* Several classes keep on using deprecated HttpHeaderDateFormat

Modifications:

* Move HttpHeaderDateFormatter to netty-codec and rename it into HeaderDateFormatter
* Make DefaultHeaders use HeaderDateFormatter
* Replace HttpHeaderDateFormat usage with HeaderDateFormatter

Result:

Faster and more consistent code

0bc30a123e Eliminate usage of releaseLater(...) to reduce memory usage during tests
Motiviation:

We used ReferenceCountUtil.releaseLater(...) in our tests which simplifies a bit the releasing of ReferenceCounted objects. The problem with this is that while it simplifies stuff it increase memory usage a lot as memory may not be freed up in a timely manner.

Modifications:

- Deprecate releaseLater(...)
- Remove usage of releaseLater(...) in tests.

Result:

Less memory needed to build netty while running the tests.

e7631867d3 LzmaFrameEncoderTest double release
Motivation:
2c78902ebc ensured buffers were released in the general case but didn't clean up an extra release in LzmaFrameEncoderTest#testCompressionOfBatchedFlowOfData which lead to a double release.

Modifications:
LzmaFrameEncoderTest#testCompressionOfBatchedFlowOfData should not explicitly release the buffer because decompress will release the buffer

Result:
No more reference count exception and failed test.

2c78902ebc LzmaFrameEncoderTest leak due to LzmaInputStream close behavior
Motivation:
c1932a8537 made an assumption that the LzmaInputStream which wraps a ByteBufInputStream would delegate the close operation to the wrapped stream. This assumption is not true and thus we still had a leak. An issue has been logged with our LZMA dependency https://github.com/jponge/lzma-java/issues/14.

Modifications:
- Force a close on the wrapped stream

Result:
No more leak.

c1932a8537 ByteBuf Input Stream Reference Count Ownership
Motivation:
Netty provides a adaptor from ByteBuf to Java's InputStream interface. The JDK Stream interfaces have an explicit lifetime because they implement the Closable interface. This lifetime may be differnt than the ByteBuf which is wrapped, and controlled by the interface which accepts the JDK Stream. However Netty's ByteBufInputStream currently does not take reference count ownership of the underlying ByteBuf. There may be no way for existing classes which only accept the InputStream interface to communicate when they are done with the stream, other than calling close(). This means that when the stream is closed it may be appropriate to release the underlying ByteBuf, as the ownership of the underlying ByteBuf resource may be transferred to the Java Stream.

Motivation:
- ByteBufInputStream.close() supports taking reference count ownership of the underyling ByteBuf

Result:
ByteBufInputStream can assume reference count ownership so the underlying ByteBuf can be cleaned up when the stream is closed.

d479e939b0 Buffer Leaks in Compression Tests
Motivation:
The unit tests for the compression encoders/decoders may write buffers to an EmbeddedChannel but then may not release buffer or close the channel after the test. This may result in buffer leaks.

Modifications:
- Call channel.finishAndReleaseAll() after each test

Result:
Fixes https://github.com/netty/netty/issues/6007

e47da7be77 CompatibleObjectEncoder cached ObjectOutputStream backed by release buffer bug
Motivation:
ObjectOutputStream uses a Channel Attribute to cache a ObjectOutputStream which is backed by a ByteBuf that may be released after an object is encoded and the underlying buffer is written to the channel. On subsequent encode operations the cached ObjectOutputStream will be invalid and lead to a reference count exception.

Modifications:
- CompatibleObjectEncoder should not cache a ObjectOutputStream.

Result:
CompatibleObjectEncoder doesn't use a cached object backed by a released ByteBuf.

e3462a79c7 MessageAggregator Potential Leak
Motivation:
MessageAggregator has a potential to leak if a new message is received before the existing message has completed, and if a HttpContent is received but maxContentLength has been exceeded, or the content length is too long.

Modifications:

- Make the HttpObjectAggregator more robust to leaks
- Reduce dependance on handlingOversizedMessage but instead rely on the more general check of a null currentMessage

Result:
More robust MessageAggregator with less chance of leaks

7db3e01498 Ensure uncompressed ByteBuf is released when an exception happens during decoding.
Motivation:

We need to ensure the uncompressed ByteBuf is released if an exception happens while calling decode(...). If we miss to do so we leak buffers.

Modifications:

Correctly release buffer on exception.

Result:

No more memory leak.

bb3c4a43d8 Lz4FrameDecoder should reduce memory copies whenever possible
Motivation:

When the user constructs Lz4FrameDecoder with a Checksum implementation like CRC32 or Adler32 and uses Java8 we can directly use a ByteBuffer to do the checksum work. This way we can eliminate memory copies.

Modifications:

Detect if ByteBuffer can be used for checksum work and if so reduce memory copies.

Result:

Less memory copies when using JDK8
