6e5fd9311f EmptyHeaders get with default value returns null
Motivation:
EmptyHeaders#get with a default value argument returns null. It should never return null, and instead it should return the default value.

Modifications:
- EmptyHeaders#get with a default value should return that default value

Result:
More correct implementation of the Headers API.

f40ecc3f10 Fix Snappy decoding of large 2-byte literal lengths and copy offsets
Motivation:

The Snappy decoder was failing on valid inputs containing literals
with 2-byte lengths > 0x8000 or copies with 2-byte offsets >= 0x8000.

The decoder was also enforcing an artificially low offset limit of
0x7FFF, something the Snappy format description advises against,
and which prevents decoding valid inputs generated by other encoders.

Modifications:

Interpret 2-byte literal lengths and 2-byte copy offsets as unsigned
shorts, in accordance with the format description and reference
implementation.

Allow any positive offset value. Throw an appropriate exception
for negative values (which can theoretically occur due to arithmetic
overflow on 4-byte offsets, but are unlikely to occur in the wild).

Result:

The Snappy decoder can handle valid inputs that previously caused
it to throw exceptions.

1e5fafe446 Simplify CharSequenceValueConverter#convertToBoolean
Motivation:
CharSequenceValueConverter#convertToBoolean has a few manual conditionals which can be removed if we use AsciiString.contentEqualsIgnoreCase. Also by comparing an AsciiString to a String we will incur conversions to char that can be avoided if we compare against AsciiString.

Modifications:
- Use AsciiString.contentEqualsIgnoreCase
- Compare against a AsciiString

Result:
Simplified CharSequenceValueConverter#convertToBoolean which favors AsciiString comparison.

756854e99a Correctly implement CharSequenceValueConvert.convertTimeMillis
Motivation:

If you pass the output of CharSequenceValueConvert.convertToTimeMillis to convertTimeMillis it will throw a ParseException.

Modifications:

- Correctly implement CharSequenceValueConverter.convertTimeMillis
- Add unit-tests for CharSequenceValueConverter

Result:

Correctly convert timemillis.

c1d0d88f0a Implement DefaultHeaders.HeaderEntry.equals()
Motivation:

HeaderEntry.equals() inherets Object.equals() which simply check if two objects are the same.
So it returns false even when two HeaderEntry objects have the same name and value.

Modifications:

Implement HeaderEntry.equals() that follows the specification of Map.Entry.equals().
https://docs.oracle.com/javase/9/docs/api/java/util/Map.Entry.html#equals-java.lang.Object-

Result:

HeaderEntry.equals() returns true if two HeaderEntry objects have the same name and value.

ad6af3250c DefaultHeaders / CharSequenceValueConverter should treat boolean consistently.
Motivation:

HttpHeaders.getBoolean should return the same truth value for the same string value, regardless of the underlying type.

Modifications:

- Only treat values of true as Boolean.TRUE
- Add unit tests.

Result:

Consistent converting of values for all CharSequence implementations.

02b7507a62 Correctly handle the case when converting of value fails and return null or default value.
Motivation:

Headers.get* methods should not throw an exception but return null or the default value if converting of the value fails.

Modifications:

- Correctly handle the case when ValueConverter throws an Exception.
- Add testcase.

Result:

Fixes [#7710].

4c1e0f596a Use FastThreadLocal for CodecOutputList
Motivation:

We used Recycler for the CodecOutputList which is not optimized for the use-case of access only from the same Thread all the time.

Modifications:

- Use FastThreadLocal for CodecOutputList
- Add benchmark

Result:

Less overhead in our codecs.

e6c9ac968d Cleanup: replaced deprecated ctx.attr() and ctx.hasAttr() methods usage with ch.attr() and ch.hasAttr().
Motivation:

Will allow easy removal of deprecated methods in future.

Modification:

Replaced ctx.attr(), ctx.hasAttr() with ctx.channel().attr(), ctx.channel().hasAttr().

Result:

No deprecated ctx.attr(), ctx.hasAttr() methods usage.

6ff48dcbe3 Fixes #7566 by handling concatenated GZIP streams.
Motivation:
According to RFC 1952, concatenation of valid gzip streams is also a valid gzip stream. JdkZlibDecoder only processed the first and discarded the rest.

Modifications:
- Introduced a constructor argument decompressConcatenated that if true, JdkZlibDecoder would continue to process the stream.

Result:
- If 'decompressConcatenated = true', concatenated streams would be processed in
compliance to RFC 1952.
- If 'decompressConcatenated = false' (default), existing behavior would remain.

c9668ce40f The constants calculation in compile-time
Motivation:
Allow pre-computing calculation of the constants for compiler where it could be.
Similar fix in OpenJDK: [1].

Modifications:
- Use parentheses.
- Simplify static initialization of `BYTE2HEX_*` arrays in `StringUtil`.

Result:
Less bytecode, possible faster calculations at runtime.

942b993f2b Only enable validation of headers if original headers were validating as well.
Motiviation:

In our replace(...) methods we always used validation for the newly created headers while the original headers may not use validation at all.

Modifications:

- Only use validation if the original headers used validation as well.
- Ensure we create a copy of the headers in replace(...).

Result:

Fixes [#5226]

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).
