Skip execution of Channel*Handler method if annotated with @Skip and … (#8988)
Motivation:

Invoking ChannelHandlers is not free and can result in some overhead when the ChannelPipeline becomes very long. This is especially true if most handlers will just forward the call to the next handler in the pipeline. When the user extends Channel*HandlerAdapter we can easily detect if can just skip the handler and invoke the next handler in the pipeline directly. This reduce the overhead of dispatch but also reduce the call-stack in many cases.

This backports https://github.com/netty/netty/pull/8723 and https://github.com/netty/netty/pull/8987 to 4.1

Modifications:

Detect if we can skip the handler when walking the pipeline.

Result:

Reduce overhead for long pipelines.

c3c05e8570 Fix NPE in OpenSslPrivateKeyMethodTest.destroy() when BoringSSL is not used
Motivation:

4079189f6b introduced OpenSslPrivateKeyMethodTest which will only be run when BoringSSL is used. As the assumeTrue(...) also guards the init of the static fields we need to ensure we only try to destroy these if BoringSSL is used as otherwise it will produce a NPE.

Modifications:

Check if BoringSSL is used before trying to destroy the resources.

Result:

No more NPE when BoringSSL is not used.

Correctly discard messages after oversized message is detected. (#9015)
Motivation:

32563bfcc1 introduced a regression in which we did now not longer discard the messages after we handled an oversized message.

Modifications:

- Do not set aggregating to false after handleOversizedMessage is called
- Adjust unit tests to verify the behaviour is correct again.

Result:

Fixes https://github.com/netty/netty/issues/9007.

9f2221ebd4 CompositeByteBuf optimizations and new addFlattenedComponents method (#8939)
Motivation:

The CompositeByteBuf discardReadBytes / discardReadComponents methods are currently quite inefficient, including when there are no read components to discard. We would like to call the latter more frequently in ByteToMessageDecoder#COMPOSITE_CUMULATOR.

In the same context it would be beneficial to perform a "shallow copy" of a composite buffer (for example when it has a refcount > 1) to avoid having to allocate and copy the contained bytes just to obtain an "independent" cumulation.

Modifications:

- Optimize discardReadBytes() and discardReadComponents() implementations (start at first comp rather than performing a binary search for the readerIndex).
- New addFlattenedComponents(boolean,ByteBuf) method which performs a shallow copy if the provided buffer is also composite and avoids adding any empty buffers, plus unit test.
- Other minor optimizations to avoid unnecessary checks.

Results:

discardReadXX methods are faster, composite buffers can be easily appended without deepening the buffer "tree" or retaining unused components.

Allow to offload / customize key signing operations when using BoringSSL. (#8943)
Motivation:

BoringSSL allows to customize the way how key signing is done an even offload it from the IO thread. We should provide a way to plugin an own implementation when BoringSSL is used.

Modifications:

- Introduce OpenSslPrivateKeyMethod that can be used by the user to implement custom signing by using ReferenceCountedOpenSslContext.setPrivateKeyMethod(...)
- Introduce static methods to OpenSslKeyManagerFactory which allows to create a KeyManagerFactory which supports to do keyless operations by let the use handle everything in OpenSslPrivateKeyMethod.
- Add testcase which verifies that everything works as expected

Result:

A user is able to customize the way how keys are signed.

a3e8c86741 Added UDP multicast (with caveats: no ipv6, getInterface, getNetworkI… (#9006)
…nterface, block or loopback-mode-disabled operations).


Motivation:

Provide epoll/native multicast to support high load multicast users (we are using it for a high load telecomm app at my day job).

Modification:

Added support for (ipv4 only) source specific and any source multicast for epoll transport. Some caveats (beyond no ipv6 support initially - there’s a bit of work to add in join and leave group specifically around SSM, as ipv6 uses different data structures for this): no support for disabling loop back mode, retrieval of interface and block operation, all of which tend to be less frequently used.

Result:

Provides epoll transport multicast for IPv4 for common use cases. Understand if you’d prefer to hold off until ipv6 is included but not sure when I’ll be able to get to that.

4373a1fba2 Increase default bits for SelfSignedCertificate (#9019)
Motivation:
During OpenSsl.java initialization, a SelfSignedCertificate is created
during the static initialization block to determine if OpenSsl
can be used.

The default key strength for SelfSignedCertificate was too low if FIPS
mode is used and BouncyCastle-FIPS is the only available provider
(necessary for compliance). A simple fix is to just augment the key
strength to the minimum required about by FIPS.

Modification:
Set default key bit length to 2048 but also allow it to be dynamically set via a system property for future proofing to more stricter security compliance.

Result:
Fixes #9018

We should fail fast if the given PrivateKey or X509Certificate chain is not supported by the used SslProvider. (#9009)
Motivation:

Some SslProvider do support different types of keys and chains. We should fail fast if we can not support the type.

Related to https://github.com/netty/netty-tcnative/issues/455.

Modifications:

- Try to parse key / chain first and if if this fails throw and SslException
- Add tests.

Result:

Fail fast.

Modifications:

Include initial handshake exception

Result:

Include all erros when throwing the SslHandshakeException.

Modifications:

- Add @SupressWarnings("deprecated")
- Clarify docs.

Result:

Less warnings and more clear deprecated docs.

Remove call to SSL.setHostNameValidation(...) as it is done in the TrustManager (#8981)
Motivation:

We do not need to call SSL.setHostNameValidation(...) as it should be done as part of the TrustManager implementation. This is consistent with the JDK implementation of SSLEngine.

Modifications:

Remove call to SSL.setHostNameValidation(...)

Result:

More consistent behaviour between our SSLEngine implementation and the one that comes with the JDK.

Fix NPE that was encounter by debugger (will never happen in real code). (#8992)
Motivation:

We synchronize on the chunk.arena when produce the String returned by PoolSubpage.toString() which may raise a NPE when chunk == null. Chunk == null for the head of the linked-list and so a NPE may raised by a debugger. This NPE can never happen in real code tho as we never access toString() of the head.

Modifications:

Add null checks and so fix the possible NPE

Result:

No NPE when using a debugger and inspect the PooledByteBufAllocator.

Use SSL.setKeyMaterial(...) to test if the KeyManagerFactory is supported (#8985)
Motivation:

We use SSL.setKeyMaterial(...) in our implementation when using the KeyManagerFactory so we should also use it to detect if we can support KeyManagerFactory.

Modifications:

Use SSL.setKeyMaterial(...) as replacement for SSL.setCertificateBio(...)

Result:

Use the same method call to detect if KeyManagerFactory can be supported as we use in the real implementation.

Consolidate creation of SslHandshakeException when caused by a callback that is used in the native SSL implementation. (#8979)
Motivation:

We have multiple places where we store the exception that was produced by a callback in ReferenceCountedOpenSslEngine, and so have a lot of code-duplication.

Modifications:

- Consolidate code into a package-private method that is called from the callbacks if needed

Result:

Less code-duplication and cleaner code.

Allow to offload certificate validation when using BoringSSL (#8974)
Motivation:

BoringSSL supports offloading certificate validation to a different thread. This is useful as it may need to do blocking operations and so may block the EventLoop.

Modification:

- Adjust ReferenceCountedOpenSslEngine to correctly handle offloaded certificate validation (just as we already have code for certificate selection).

Result:

Be able to offload certificate validation when using BoringSSL.

Don't try to put back MemoryRegionCache.Entry objects into the Recycler when recycled because of a finalizer. (#8955)
Motivation:

In MemoryRegionCache.Entry we use the Recycler to reduce GC pressure and churn. The problem is that these will also be recycled when the PoolThreadCache is collected and finalize() is called. This then can have the effect that we try to load class but the WebApp is already stoped.

This will produce an stacktrace like this on Tomcat:

```
19-Mar-2019 15:53:21.351 INFO [Finalizer] org.apache.catalina.loader.WebappClassLoaderBase.checkStateForResourceLoading Illegal access: this web application instance has been stopped already.

```

Beside this we also need to ensure we not try to lazy load SizeClass when the finalizer is used as it may not be present anymore if the ClassLoader is already destroyed.

This would produce an error like:

```

Modifications:

- Only try to put the Entry back into the Recycler if the PoolThredCache is not destroyed because of the finalizer.
- Only try to access SizeClass if not triggered by finalizer.

Result:

b36f75044f Fix possible ByteBuf leak when CompositeByteBuf is resized (#8946)
Motivation:

The special case fixed in #8497 also requires that we keep a derived slice when trimming components in place, as done by the capacity(int) and discardReadBytes() methods.

Modifications:

Ensure that we keep a ref to trimmed components' original retained slice in capacity(int) and discardReadBytes() methods, so that it is released properly when the they are later freed. Add unit test which fails prior to the fix.

Result:

Edge case leak is eliminated.

Allow to automatically trim the PoolThreadCache in a timely interval (#8941)
Motivation:

PooledByteBufAllocator uses a PoolThreadCache per Thread that allocates / deallocates to minimize the performance overhead. This PoolThreadCache is trimmed after X allocations to free up buffers that are not allocated for a long time. This works out quite well when the app continues to allocate but fails if the app stops to allocate frequently (for whatever reason) and so a lot of memory is wasted and not given back to the arena / freed.

Modifications:

- Add a ThreadExecutorMap that offers multiple methods that wrap Runnable / ThreadFactory / Executor and allow to call ThreadExecutorMap.currentEventExecutor() to get the current executing EventExecutor for the calling Thread.
- Use these methods in the constructors of our EventExecutor implementations (which also covers the EventLoop implementations)
- Add io.netty.allocator.cacheTrimIntervalMillis system property which can be used to specify a fixed rate / interval on which we should try to trim the PoolThreadCache for a EventExecutor that allocates.
- Add PooledByteBufAllocator.trimCurrentThreadCache() to allow the user to trim the cache of the calling thread manually.
- Add testcases
- Introduce FastThreadLocal.getIfExists()

Result:

Allow to better / more frequently trim PoolThreadCache and so give back memory to the area / system.

e7b3195570 Support ALLOW_HALF_CLOSURE channel option on Unix domain socket. (#8932)
Motivation:

Since DomainSocketChannel is a DuplexChannel,  which be able to shutdown input or output individually on demands, but ALLOW_HALF_CLOSURE channel option has not been supported yet.

I thought this could be a missing feature of Unix domain socket, so here the PR for it.

Modifications:

1. Added allHalfClosure property both in  EpollDomainSocketChannelConfig and KQueueDomainSocketChannelConfig,
2. Enabled isAllowHalfClosure method of native channel to support domain channel config,

eb1d12c757 Expose the global direct memory counter. (#8945)
Motivation:
This counter is very useful in order to monitor Netty without having every ByteBufAllocator in the JVM

Modification:
Expose the value of DIRECT_MEMORY_COUNTER as we are already doing for DIRECT_MEMORY_LIMIT.
We are returning -1 in case that DIRECT_MEMORY_COUNTER is not available.

Result:

Be able to get the amount of direct memory used.

Correctly produce ssl alert when certificate validation fails on the client-side when using native SSL implementation. (#8949)
Motivation:

When the verification of the server cert fails because of the used TrustManager on the client-side we need to ensure we produce the correct alert and send it to the remote peer before closing the connection.

Modifications:

- Use the correct verification mode on the client-side by default.
- Update tests

Result:

Fixes https://github.com/netty/netty/issues/8942.

Adjust testsuite-osgi to resolve bundles from local build (#8944)
Motivation:

testsuite-osgi currently resolve its bundles from the local / remote maven repository, which means you will need to do `mvn install` before it can pick up the bundles. Beside this this also means that you may pick up old versions if you forgot to call `install` before running it.

Modifications:

Use alta-maven-plugin to be able to resolve bundles from the local build directory during the build.

Result:

No need to install jars before running the OSGI testsuite and ensure we always test with the latest jars.

c8daea3045 Fix HttpUtil.isKeepAlive to behave correctly when Connection is a comma separated list (#8924)
Motivation:

According to the specification, the "Connection" header's syntax is:

"
The Connection header field's value has the following grammar:

     Connection        = 1#connection-option
     connection-option = token

Connection options are case-insensitive.
"
https://tools.ietf.org/html/rfc7230#section-6.1

This means that Connection's value can have at least one element or
a comma separated list with elements
When calculating whether the connection can remain open,
HttpUtil.isKeepAlive(HttpMessage) should take this into account.

Modifications:

- Check for "close" and "keep-alive" in a comma separated list
- Add unit test

Result:

HttpUtil.isKeepAlive(HttpMessage) works correctly when "Connection: Upgrade, close"

Fail build when Illegal reflective access is detected (#8933)
Motivation:

We want to make the experience as smooth as possible for our users when using Java9+ and so should ensure we do not produce any 'Illegal reflective access' errors when using netty.

Modifications:

Add jvmArgs when running our tests that will deny reflective access and so will fail the build at the end due not be able to load some classes.

Result:

Ensure we do not produce any illegal refelctive access errors when using java9+
