Http2FrameLogger should not extend ChannelHandlerAdapter (#9002)
Motivation:

For what-ever reason Http2FrameLogger did extend ChannelHandlerAdapter but not override any of its methods. We should not extend it at all as it is not a ChannelHandler.

Modifications:

Remove extends

Result:

Less confusing / more correct / clear code.

6b8a0ed374 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.

1eabb752c0 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.

Change default of io.netty.allocator.useCacheForAllThreads to false (#8991)
Motivation:

We currently use a thread local cache for all threads which often is suprising to users as it may result in a lot of memory usage if they allocate buffers from outside the EventLoop in different threads. We should better not do this by default to keep suprises to a minimum. Users that need the performance and know what they are doing can still change this.

Modifications:

Change io.netty.allocator.useCacheForAllThreads to false by default

Result:

Related to https://github.com/netty/netty/issues/8536.

07244a194f 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.

Move ChannelHandler.Skip to ChannelHandlerMask.Skip and make it packa… (#8987)
Motivation:

8fdf373557 introduced the @Skip annotation which allows to optimize the way we invoke ChannelHandlers when traversing the pipeline. Now that we moved all the "default" code to the ChannelHandler interface we can make the annotation package-private to guard the user to make any mistakes which will lead to hard to debug issues.

Modifications:

Move ChannelHandler.Skip to ChannelHandlerMask.Skip and make it package-private

Result:

Guard users from introduce hard to debug issues.

Merge ChannelInboundHandler and ChannelOutboundHandler into ChannelHa… (#8957)
Motivation:

In 42742e233f we already added default methods to Channel*Handler and deprecated the Adapter classes to simplify the class hierarchy. With this change we go even further and merge everything into just ChannelHandler. This simplifies things even more in terms of class-hierarchy.

Modifications:

- Merge ChannelInboundHandler | ChannelOutboundHandler into ChannelHandler
- Adjust code to just use ChannelHandler
- Deprecate old interfaces.

Result:

Cleaner and simpler code in terms of class-hierarchy.

231eb145f1 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.

1736b0e6a8 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.

a817e30d41 Add SSLEngineTest to ensure Signature Algorithms are present during KeyManager calls. (#8965)
Motivation:

We had a bug which could case ExtendedSSLSession.getPeerSupportedSignatureAlgorithms() return an empty array when using BoringSSL. This testcase verifies we correctly return algorithms after the fix in https://github.com/netty/netty-tcnative/pull/449.

Modifications:

Add testcase to verify behaviour.

Result:

Ensure we correctly retuen the algorithms.

d3535d31be Correctly detect exeception cause when using BoringSSL in SslErrorTest
Motivation:

e9ce5048df added a testcase to ensure we correctly send the alert in all cases but did use a too strict message matching which did not work for BoringSSL as it not uses whitespaces but underscores.

Modifications:

Make the message matching less strict.

Result:

Test pass also when using BoringSSL.

ab7accb2de 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. Could not load [java.util.WeakHashMap]. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.

```

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:

No IllegalStateException anymoe when a webapp is reloaded in Tomcat that uses netty and uses the PooledByteBufAllocator.

a71e33ae35 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.

9681842d54 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.

238018e4ea 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,
3. Created EpollDomainSocketShutdownOutputByPeerTest and KQueueDomainSocketShutdownOutputByPeerTest to verify the change.

Result:

ALLOW_HALF_CLOSURE channel option can be set with DomainSocketChannel, and no more warning of Unknown channel option 'ALLOW_HALF_CLOSURE'.

07514467e3 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.

a44c33136f 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"

Deprecate ChannelInboundHandlerAdapter and ChannelOutboundHandlerAdapter (#8929)
Motivation:

As we now us java8 as minimum java version we can deprecate ChannelInboundHandlerAdapter / ChannelOutboundHandlerAdapter and just move the default implementations into the interfaces. This makes things a bit more flexible for the end-user and also simplifies the class-hierarchy.

Modifications:

- Mark ChannelInboundHandlerAdapter and ChannelOutboundHandlerAdapter as deprecated
- Add default implementations to ChannelInboundHandler / ChannelOutboundHandler
- Refactor our code to not use ChannelInboundHandlerAdapter / ChannelOutboundHandlerAdapter anymore

7e76d02fe7 ReferenceCountedOpenSslEngines SSLSession must provide local certific… (#8918)
Motivation:

The SSLSession that is returned by SSLEngine.getHandshakeSession() must be able to provide the local certificates when the TrustManager is invoked on the server-side.

Modifications:

- Correctly return the local certificates
- Add unit test

Result:

Be able to obtain local certificates from handshake SSLSession during verification on the server side.

10f06a04e6 HttpContentDecoder must continue read when it did not produce any mes… (#8922)
Motivation:

When HttpContentDecoder (and so HttpContentDecompressor) does not produce any message we need to make sure it calls ctx.read() if auto read is false to not stale.

Modifications:

- Keep track if we need to call ctx.read() or not
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/8915.

2689f28cb7 Do not use GetPrimitiveArrayCritical(...) due multiple not-fixed bugs… (#8921)
* Do not use GetPrimitiveArrayCritical(...) due multiple not-fixed bugs related to GCLocker

Motivation:

GetPrimitiveArrayCritical(...) may cause multiple not-fixed bugs related to the GCLocker while there is little gain for our use-case. We should just use GetByteArrayRegion(...) and copy into a small on-stack buffer.

See also:

- https://bugs.openjdk.java.net/browse/JDK-8048556

- https://bugs.openjdk.java.net/browse/JDK-8057586

Special thanks to @jayv @shipilev @apangin for the pointers.

Modifications:

Replace GetPrimitiveArrayCritical(...) with GetByteArrayRegion(...)

Result:

Less risks hitting GCLocker related bugs.

22128a85fe Add interopt tests between Conscrypt and OpenSSL SSLEngine implementations. (#8919)
Motivation:

In the past we found a lot of SSL related bugs because of the interopt tests we have in place between different SSLEngine implementations. We should have as many of these interopt tests as possible for this reason.

Modifications:

- Add interopt tests between Conscrypt and OpenSSL SSLEngine implementations

Result:

More tests for SSL.

902cdaae56 Carefully manage Keep-Alive connections in HttpStaticFileServer (#8914)
Motivation:

Simple rules:

* close the connection when sending any error
* specify "Connection: close" header when closing the connection
* successful responses should keep the connection intact when otherwise is not requested by the client

Modifications:

* "send response and cleanup the connection" logic moved to a helper
* for all successful responses set "Content-Lenght" header
* do not specify "Connection: Keep-Alive" header as far it's a default for HTTP/1.1
* set "Connection: close" header when necessary

Result:

Keep-Alive connections management is inlined with RFCs.

b2dc54c8c6 Support delegating task when using ReferenceCountedOpenSslEngine. (#8859)
Motivation:

SSLEngine API has a notion of tasks that may be expensive and offload these to another thread. We did not support this when using our native implementation but can now for various operations during the handshake.

Modifications:

- Support offloading tasks during the handshake when using our native SSLEngine implementation
- Correctly handle the case when NEED_TASK is returned and nothing was consumed / produced yet

Result:

Be able to offload long running tasks from the EventLoop when using SslHandler with our native SSLEngine.

6c4d6ae332 Correctly monkey-patch id also in whe os / arch is used within library name. (#8913)
Motivation:

2bb9f64e16 introduced a change which made it possible to use different shaded versions of netty-tcnative on the classpath. This only partly worked as we did not correctly handled the case when os / arch is part of the library name (which is the case when netty-tcnative-boringssl-static is used with the uber jar).

Modifications:

- If patching the ID failed we retry again with the os / arch stripped
- Add unit tests to verify that patching ID now works with and without os / arch as suffix.

Result:

Using multiple shaded version of netty-tcnative-boringssl-static on MacOS works.

c6b372f517 Use maven plugin to prevent API/ABI breakage as part of build process (#8904)
Motivation:

Netty is very widely used which can lead to a lot of pain when we break API / ABI. We should make use japicmp-maven-plugin during the build to verify we do not introduce breakage by mistake.

Modifications:

- Add japicmp-maven-plugin to the build process
- Fix a method signature change in HttpProxyHandler that was flagged as a possible problem.

Result:

Ensure no API/ABI breakage accour between releases.

71d8d057e6 Only remove ReferenceCountedOpenSslEngine from OpenSslEngineMap when engine is destroyed (#8905)
Motivation:

We must only remove ReferenceCountedOpenSslEngine from OpenSslEngineMap when engine is destroyed as the verifier / certificate callback may be called multiple times when the remote peer did initiate a renegotiation.
If we fail to do so we will cause an NPE like this:

While the exception is kind of harmless (as we will reject the renegotiation at the end anyway) it produces some noise in the logs.

Modifications:

Don't remove engine from map after handshake is complete but wait for it to be removed until the engine is destroyed.

Result:

No more NPE and less noise in the logs.

795f9600ba Adjust tests to be able to build / test when using IBM J9 / OpenJ9 (#8900)
Motivation:

We should run a CI job using J9 to ensure netty also works when using different JVMs.

Modifications:

- Adjust PooledByteBufAllocatorTest to be able to complete faster when using a JVM which takes longer when joining Threads (this seems to be the case with J9).

Result:

Be able to run CI against J9.

94ffd28973 Close consumed inputs in ChunkedWriteHandler (#8876)
Motivation:

ChunkedWriteHandler needs to close both successful and failed
ChunkInputs. It used to never close successful ones.

Modifications:

* ChunkedWriteHandler always closes ChunkInput before completing
the write promise.
* Ensure only ChunkInput#close() is invoked
on a failed input.
* Ensure no methods are invoked on a closed input.

Result:

Fixes https://github.com/netty/netty/issues/8875.
