8b123a5546 Fix AbstractChannelTest errors caused by incorrect mocking
Motivation:

In AbstractChannelTest we not correctly mocked some methods which could lead to test errors. That said it only showed up here when running from the IDE and not from the cmdLine.

Modifications:

Mock methods that are needed for the test

Result:

Test pass in the IDE as well.

3c5abaa39a Correctly handle non handshake commands when using SniHandler
Motivation:

As we can only handle handshake commands to parse SNI we should try to skip alert and change cipher spec commands a few times before we fallback to use a default SslContext.

Modifications:

- Use default SslContext if no application data command was received
- Use default SslContext if after 4 commands we not received a handshake command
- Simplify code
- Eliminate multiple volatile fields
- Rename SslConstants to SslUtils
- Share code between SslHandler and SniHandler by moving stuff to SslUtils

Result:

Correct handling of non handshake commands and cleaner code.

4d854cc149 Allow to change if EmbeddedChannel should handle close() and disconnect() different.
Motivation:

At the moment EmbeddedChannel always handle close() and disconnect() the same way which also means that ChannelOutboundHandler.disconnect(...) will never called. We should allow to specify if these are handle different or not to make the use of EmbeddedChannel more flexible.

Modifications:

Add 2 other constructors which allow to specify if disconnect / close are handled the same way or differently.

Result:

More flexible usage of EmbeddedChannel possible.

45674baf3e Correctly report *LE operations when advanced leak detection is used.
Motivation:

We missed reporting *LE operations when AdvancedLeakAwareByteBuf was used. This could lead to incomplete access reports.

Modifications:

Correctly record access for *LE operations.

Result:

Correct leak reports.

f41aa306e9 Remove multiple calls to recordLeakNonRefCountingOperation() in AdvancedLeakAwareByteBuf.forEachByteDesc
Motivation:

AdvancedLeakAwareByteBuf.forEachByteDesc(...) called recordLeakNonRefCountingOperation() two times which resulted in incorrect leak detection reports.

Modifications:

Remove duplicated call to recordLeakNonRefCountingOperation()

Result:

Correct leak detection results

da01b1daec Decryption failed or bad mac record in Android 5.0
Motivation:

Android 5.0 (API version 21) has a bug which not correctly set the bytesConsumed of SSLEngineResult when HandshakeStatus is FINISHED.  Because of this we need to special handle the status and so workaround the Android bug.

Modifications:

- Break the unwrap for (;;) loop when HandshakeStatus is FINISHED and bytesConsumed == 0 && bytesProduced == 0.

Result:

SslHandler works with all known version of Android.

9ae155d257 Fix InternalAttribute.equals
Motivation:

InternalAttribute doesn't extend Attribute, but its equals only returns true when it compares with an Attribute. So it will return false when comparing with itself.

Modifications:

Make sure InternalAttribute return false for non InternalAttribute objects.

Result:

InternalAttribute's equals works correctly.

b4be040f30 Introduce DnsCache API + DnsResolver extensibility
Motivation:
Caching is currently nested in DnsResolver.
It should also be possible to extend DnsResolver to ba able to pass a different cache on each resolution attemp.

Modifications:

* Introduce DnsCache, NoopDnsCache and DefaultDnsCache. The latter contains all the current caching logic that was extracted.
* Introduce protected versions of doResolve and doResolveAll that can be used as extension points to build resolvers that bypass the main cache and use a different one on each resolution.

Result:

Isolated caching logic. Better extensibility.

07d0bcab8c Fix deprecated Maven expressions usage
Motivation:

Parent pom.xml uses deprecated maven expressions, such as `${groupId}`
which should be ${project.groupId}.
This causes tons of warnings on every module in the build.

Modifications:

Use up to date syntax.

Result:

No more maven warnings.

0c733e1425 [#2363] Correctly null out SelectionKey[] when selectAgain
Motivation:

The prefix fix of #2363 did not correctly handle the case when selectAgain is true and so missed to null out entries.

Modifications:

Move the i++ from end of loop to beginning of loop

Result:

Entries in the array will be null out so allow to have these GC'ed once the Channel close

1bee71fb1c Fix PlatformDependent.newAtomic*FieldUpdater type safety
Motivation:

* newAtomicIntegerFieldUpdater and newAtomicLongFieldUpdater take a
class<?> so they're too lax
* newAtomicReferenceFieldUpdater takes a Class<U> so it's too strict
and can only be passe a rawtype parameter when dealing w/ generic
classes

Modifications:

Take a Class<? super T> parameter instead.

Result:

Better type safety and generics support.

e578134b57 Unpooled and Wrapped Buffer Leak
Motivation:
There are a few buffer leaks related to how Unpooled.wrapped and Base64.encode is used.

Modifications:
- Fix usages of Bas64.encode to correct leaks
- Clarify interface of Unpooled.wrapped* to ensure reference count ownership is clearly defined.

Result:
Reference count code is more clearly defined and less leaks are possible.

e7af3ee970 [#4658] Fix encoding of pom.xml file
Motivation:

transport-native-epoll has its pom.xml encoding attribute set to ISO-8859-15. Because
of this gradle, and other dependency management systems, can't correctly resolve this
library from wherever it happens to be published.

Modifications:

netty/transport-native-epoll/pom.xml had its xml encoding changed to UTF-9

Result:

Gradle, and other dependency management systems, will now be able to correctly resolve this module.

a157528ec2 Ensure we only add OpenSslEngine to the OpenSslEngineMap when handshake is started
Motivation:

We need to ensure we only add the OpenSslEngine to the OpenSslEngineMap when the handshake is started as otherwise we may produce a memory leak when the OpenSslEngine is created but not actually used. This can for example happen if we encounter a connection refused from the remote peer. In this case we will never remove the OpenSslEngine from the OpenSslEngineMap and so it will never be collected (as we hold a reference). This has as affect that the finalizer will never be run as well.

Modifications:

- Lazy add the OpenSslEngine to the OpenSslEngineMap to elimate possible leak.
- Call OpenSslEngine.shutdown() when SslHandler is removed from the ChannelPipeline to free memory asap in all cases.

Result:

No more memory leak with OpenSslEngine if connection is refused.

4cdbe39284 [#4635] Stop decoding if decoder was removed
Motivation:

We need to check if this handler was removed before continuing with decoding.
If it was removed, it is not safe to continue to operate on the buffer.

Modifications:

Check if decoder was removed after fire messages through the pipeline.

Result:

No illegal buffer access when decoder was removed.

9e1e4f79c7 Fix SctpMessage.duplicate() behavior
Motivation:

SctpMessage.duplicate() copied message content that leads to additional buffer
allocation and memory copying.

Modifications:

Duplicate message content instead of copying it.

Result:

Better performace and less memory consumption.

bf2a99518c Simplify synchronized syntax
Motivation:

We often used synchronized(this) while the whole method was synchronized, which can be simplified by just mark the whole method as synchronized.

Modifications:

Replace synchronized(this) with synchronized on the method

Result:

55af6f1552 Use jetty-alpn-agent to simplify pom.xml
Motivation:

We had to add a new profile for each OpenJDK/OracleJDK release to make
Maven choose the correct alpn-boot.jar and npn-boot.jar. As a result,
our pom.xml has a large number of `<profile/>` sections.

Modifications:

- Use jetty-alpn-agent, which chooses the correct alpn-boot.jar and
  npn-boot.jar automatically to remove all the nasty profile sections
  from pom.xml
  - Visit https://github.com/trustin/jetty-alpn-agent for more info

Result:

Cleaner pom.xml

8732745264 OpenSslEngine skip ALPN tests if OpenSsl version doesn't support ALPN
Motivation:
OpenSslEngine now tests ALPN behavior. However it is possible that OpenSSL is present, but the version does not support ALPN. This will result in test failures instead of just skipping the test.

Modifications:
- Skip ALPN tests in OpenSslEngineTest if the version of OpenSSL does not support ALPN

Result:
Tests don't fail due to unsupported feature in OpenSSL.

fd5316ed6f ChunkedInput.readChunk parameter of type ByteBufAllocator
Motivation:
ChunkedInput.readChunk currently takes a ChannelHandlerContext object as a parameters. All current implementations of this interface only use this object to get the ByteBufAllocator object. Thus taking a ChannelHandlerContext as a parameter is more restrictive for users of this API than necessary.

Modifications:
- Add a new method readChunk(ByteBufAllocator)
- Deprecate readChunk(ChannelHandlerContext) and updates all implementations to call readChunk(ByteBufAllocator)

Result:
API that only requires ByteBufAllocator to use ChunkedInput.

d59bf84ef2 [#4435] Always invoke the actual deregisteration later in the EventLoop.
Motivation:

As a user may call deregister() from within any method while doing processing in the ChannelPipeline,  we need to ensure we do the actual deregister operation later. This is needed as for example,  we may be in the ByteToMessageDecoder.callDecode(...) method and so still try to do processing in the old EventLoop while the user already registered the Channel to a new EventLoop. Without delay, the deregister operation this could lead to have a handler invoked by different EventLoop and so threads.

Modifications:

Ensure the actual deregister will be done later on and not directly when invoked.

Result:

Calling deregister() within ByteToMessageDecoder.decode(..) is safe.

80f45d6ae5 Ensure closing a Socket / FileDescriptor multiple times will not throw exception
Motivation:

cfd6793bb7 Customizable estimation for messages written outside the EventLoop
Motivation:

Estimation algorithm currently used for WriteTasks is complicated and
wrong. Additionally, some code relies on outbound buffer size
incremented only on actual writes to the outbound buffer.

Modifications:

- Throw away the old estimator and replace with a simple algorithm that
  uses the client-provided estimator along with a statically configured
  WriteTask overhead (io.netty.transport.writeTaskSizeOverhead system
  property with the default value of 48 bytes)
- Add a io.netty.transport.estimateSizeOnSubmit boolean system property
  allowing the clients to disable the message estimation outside the
  event loop

Result:

Task estimation is user controllable and produces better results by
default

Motivation:
If the stream window is negative UniformStreamByteDistributor may write data. This is prohibited by the RFC https://tools.ietf.org/html/rfc7540#section-6.9.2.

Modifications:
- UniformStreamByteDistributor should use StreamState.isWriteAllowed()
