HTTP/2 child channel read cycle doesn't respect RecvByteBufAllocator and (#8147)
Motivation:
Http2MultiplexCodec queues data internally if data is delivered from the
parent channel but the child channel did not request data. If the parent
channel notifies of a stream closure it is possible data in the queue
will be discarded before closing the channel.
Http2MultiplexCodec interacts with RecvByteBufAllocator to control the
child channel's demand for read. However it currently only ever reads a
maximum of one time per loop. This can thrash the read loop and bloat
the call stack if auto read is on, because channelReadComplete will
re-enter the read loop synchronously, and also neglect to deliver data
during the parent's read loop (if it is active). This also meant the
readPendingQueue was not utilized as originally intended (to extend the
child channel's read loop during the parent channel's read loop if
demand for data still existed).

Modifications:
- Modify the child channel's read loop to respect the
RecvByteBufAllocator, and append to the parents readPendingQueue if
appropriate.
- Stream closure notification behaves like EPOLL and KQUEUE transports
and reads all queued data, because the data is already queued in memory
and it is known there will be no more data. This will also replenish the
connection flow control window which may otherwise be constrained by a
closed stream.

Result:
More correct read loop and less risk of dropping data.

Allow to validate sni hostname with underscore (#8150)
Motivation:

We should allow to also validate sni hostname which contains for example underscore when using our native SSL impl. The JDK implementation does this as well.

Modifications:

- Construct the SNIHostName via byte[] and not String.
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/8144.

Leak detection combined with composite buffers results in incorrectly handled writerIndex when calling ByteBufUtil.writeAscii/writeUtf8 (#8153)
Motivation:

We need to add special handling for WrappedCompositeByteBuf as these also extend AbstractByteBuf, otherwise we will not correctly adjust / read the writerIndex during processing.

Modifications:

- Add instanceof checks for WrappedCompositeByteBuf as well.
- Add testcases

Result:

Fixes https://github.com/netty/netty/issues/8152.

DefaultPromise.getNow() does not correctly handle DefaultPromise.setUncancellable() (#8154)
Motivation:

We do not correctly check for previous calles of setUncancellable() in getNow() which may result in ClassCastException as we incorrectly return the internally UNCANCELLABLE object and not null if setUncancellable() we as called before.

Modifications:

Correctly check for UNCANCELLABLE and add unit test.

Result:

Fixes https://github.com/netty/netty/issues/8135.

Support the usage of SocketOption when nio is used and the java versi… (#8085)
* Support the usage of SocketOption when nio is used and the java version >= 7.

Motivation:

The JDK uses SocketOption since java7 to support configuration options on the underyling Channel. We should allow to create a ChannelOption from a given SocketOption if nio is used. This also allows us to expose the same featureset in terms of configuration as the java nio implementation does without any extra effort.

Modifications:

- Add NioChannelOption which allows to wrap an existing SocketOption which then can be applied to the nio transport.
- Add test-cases

Result:

Support the same configuration options as the JDK. Also fixes https://github.com/netty/netty/issues/8072.

Add integration test for shading native libraries. (#8123)
Motivation:

It's easy to break the support for shading native libs as shown in https://github.com/netty/netty/issues/8090. We should have some testing to ensure all works as expected.

Modification:

Add new testsuite which verifies that shading our native transports work as expected.

Result:

Include test to verify shading of native code.

Fix possible NPE introduced by a137291ad1 when using SslProvider.OPENSSL and init via files or OpenSslX509KeyManagerFactory (#8126)
Motivation:

a137291ad1 introduced a way to get the most speed out of OpenSSL by not only caching keymaterial but pre-compute these. The problem was we missed to check for null before doing an instanceof check and then a cast which could lead to a NPE as we tried to cast null to Exception and throw it.

Modifications:

Add null check and unit test.

Result:

No more NPE when keymaterial was not found for requested alias.

Fix length calculation in AsciiString.indexOf(...) and so eliminate ArrayIndexOutOfBoundsException. (#8116)
Motivation:

We incorrectly calculated the length that was used for our for loop in AsciiString.indexOf(...). This lead to a possible ArrayIndexOutOfBoundsException.

- Not include the start in the length calculation
- Add unit test.

Fix incorrect code in javadocs of ChannelHandler. (#8115)
Motivation:

Some code that was shown as part of the ChannelHandler javadoc was not 100 % correct and used some constructs that we used in netty 3. Also we never called flush() in the code which is a bad example for users.

Modifications:

- Remove netty 3 code references
- Replace channel.write(...) with ctx.writeAndFlush(...)

Result:

More correct code in the javadocs.

* Add OpenSslX509KeyManagerFactory which makes it even easier for people to get the maximum performance when using OpenSSL / LibreSSL / BoringSSL  with netty.

Motivation:

To make it even easier for people to get the maximum performance when using native SSL we should provide our own KeyManagerFactory implementation that people can just use to configure their key material.

Modifications:

- Add OpenSslX509KeyManagerFactory which users can use for maximum performance with native SSL
- Refactor some internal code to re-use logic and not duplicate it.

Result:

Easier to get the max performance out of native SSL implementation.

Guard against calling PoolThreadCache.free() multiple times. (#8108)
Motivation:

5b1fe611a6 introduced the usage of a finalizer as last resort for PoolThreadCache. As we may call free() from the FastThreadLocal.onRemoval(...) and finalize() we need to guard against multiple calls as otherwise we will corrupt internal state (that is used for metrics).

Modifications:

Use AtomicBoolean to guard against multiple calls of PoolThreadCache.free().

Result:

No more corruption of internal state caused by calling PoolThreadCache.free() multuple times.

0920738932 Do not log explicit no unsafe, fixes helper method. (#8111)
Motivation:

Users should not see a scary log message when Netty is initialized if
Netty configuration explicitly disables unsafe. The log message that
produces this warning was previously guarded but by recent refactoring
a bug was introduced inside the guard helper method.

Modifications:

This commit brings back the guard against the scary log message if
unsafe is explicitly disabled.

Result:

No log message is produced when unsafe is unavailable because Netty was
told to not look for it.

fef462c043 Deprecate Unpooled.unmodifiableBuffer(ByteBuf...) (#8096)
Motivation:

Recent PR https://github.com/netty/netty/pull/8040 introduced
Unpooled.wrappedUnmodifiableBuffer(ByteBuf...) which has the same
behaviour but wraps the provided array directly. This is preferred for
most uses (including varargs-based use) and if there are any unusual
cases of an explicit array which is re-used before the ByteBuf is
finished with, it can just be copied first.

Modifications:

Added @Deprecated annotation and javadoc to
Unpooled.unmodifiableBuffer(ByteBuf...).

Result:

Unpooled.unmodifiableBuffer(ByteBuf...) will be deprecated.

7f95506132 Don't send a RST on close of the stream may not have existed (#8086)
Motivation:

When a Http2MultiplexCodec stream channel fails to write the first
HEADERS it will forcibly close, and that will trigger sending a
RST_STREAM, which is commonly a connection level protocol error. This is
because it has what looks like a valid stream id, but didn't check with
the connection as to whether the stream may have actually existed.

Modifications:

Instead of checking if the stream was just a valid looking id ( > 0) we
check with the connection as to whether it may have existed at all.

Result:

We no longer send a RST_STREAM frame from Http2MultiplexCodec for idle
streams.

fa8f967852 netty_unix_socket free nettyClassName after using it
Motivation:
netty_unix_socket attempts to use nettyClassName in an error message, but previously freed the memory. We should wait to free the memory until after we use it.

Modifications:
- Free nettyClassName after using it in snprintf

Result:
More useful error message.

HTTP/2 goaway connection state update sequencing (#8080)
Motivation:
The Http2Connection state is updated by the DefaultHttp2ConnectionDecoder after the frame listener is notified of the goaway frame. If the listener sends a frame synchronously this means the connection state will not know about the goaway it just received and we may send frames that are not allowed on the connection. This may also mean a stream object is created but it may never get taken out of the stream map unless some other event occurs (e.g. timeout).

Modifications:
- The Http2Connection state should be updated before the listener is notified of the goaway
- The Http2Connection state modification and validation should be self contained when processing a goaway instead of partially in the decoder.

Result:
No more creating streams and sending frames after a goaway has been sent or received.

Fix support for shading native libraries which was broken in b818852cdb. (#8091)
Motivation:

b818852cdb broke support for shading the native libraries in netty as it missed to respect the package prefix that is used when shading.

Modifications:

Correctly respect package prefix for constructor argument and include the used classname when logging that we could not find the constructor.

Result:

Be able to shade native libraries of netty again.

253522fc91 Create SimpleUserEventChannelHandler convenience class (#7991)
Motivation:

Currently, the vast majority of userEventTriggered() implementations
require the user to supply the boilerplate behavior of performing an
instanceof check, handling if appropriate, and calling
fireUserEventTriggered() otherwise.

We can simplify this very common use case by creating a class that only
matches user events of a given type, similar to the existing
SimpleChannelInboundHandler class.

Modifications:

Create a new SimpleUserEventChannelHandler class
Create accompanying SimpleUserEventChannelHandlerTest class

Result:

Users will be able to handle most events in a less verbose manner.

Replace toArray(new T[size]) with toArray(new T[0]) to eliminate zero-out and allow the VM to optimize. (#8075)
Motivation:

Using toArray(new T[0]) is usually the faster aproach these days. We should use it.

See also https://shipilev.net/blog/2016/arrays-wisdom-ancients/#_conclusion.

Modifications:

Replace toArray(new T[size]) with toArray(new T[0]).

HTTP/2 outbound event after receiving go_away forces sending a go_away (#8069)
Motivation:
If the local endpoint receives a GO_AWAY frame and then tries to write a stream with a streamId higher than the last know stream ID we will throw a connection error. This results in the local peer sending a GO_AWAY frame to the remote peer, but this is not necessary as the error can be isolated to the local endpoint and communicated via the ChannelFuture return value.

Modifications:
- Instead of throwing a connection error, throw a stream error that simulates the peer receiving the stream and replying with a RST

Result:
Connections are not closed abruptly when trying to create a stream on the local endpoint after a GO_AWAY frame is received.

Only try to call SSL.setHostnameValidation(...) if needed. (#8074)
Motivation:

As the used OpenSSL version may not support hostname validation we should only really call SSL.setHostNameValidation(...) if we detect that its needed.

Modifications:

Only call SSL.setHostNameValidation if it was disabled before and now it needs to be enabled or if it was enabled before and it should be disabled now.

Result:

Less risk of an exception when using an OpenSSL version that does not support hostname validation.

Update to netty-tcnative 2.0.12.Final (#8073)
Motivation:

A new version of tcnative was released that allows to use features depending on the runtime version of openssl, which makes it possible to use KeyManagerFactory and hostname verification on newer versions of centos/fedora/rhel and debian/ubuntu without the need to compile again.

Modifications:

Update to 2.0.12.Final

Result:

Use latest version of netty-tcnative to support more features.

Remove usage of ObjectCleaner (#8064)
Motivation:

ObjectCleaner does start a Thread to handle the cleaning of resources which leaks into the users application. We should not use it in netty itself to make things more predictable.

Modifications:

- Remove usage of ObjectCleaner and use finalize as a replacement when possible.
- Clarify javadocs for FastThreadLocal.onRemoval(...) to ensure its clear that remove() is not guaranteed to be called when the Thread completees and so this method is not enough to guarantee cleanup for this case.

Result:

Fixes https://github.com/netty/netty/issues/8017.

OpenSSL (and so netty-tcnative) should allow to use custom engine. (#8050)
Motivation:

OpenSSL allows to use a custom engine for its cryptographic operations. We should allow the user to make use of it if needed.

See also: https://www.openssl.org/docs/man1.0.2/crypto/engine.html.

Modifications:

Add new system property which can be used to specify the engine to use (null is the default and will use the build in default impl).

Result:

More flexible way of using OpenSSL.

34b25dc94c Expose channel count for FixedChannelPool (#8059)
Motivation:

We use FixedChannelPool in production, and we believe we have a leak that doesn't return sockets to the pool (but they should be closed), thus blocking us from creating new connections when we need them. I haven't confirmed this yet, but right now I have to resort to reflection to access this field which makes me sad.

Modification:

Expose the acquiredChannelCount field through a getter method.

Result:

Allows introspection of the pool size in FixedChannelPool.

d5d1b898d5 Reorder channel state changes in Http2MultiplexCodec child channel
Motivation:

If a write fails for a Http2MultiplexChannel stream channel, the channel
may be forcibly closed, but only after the promise has been failed. That
means continuations attached to the promise may see the channel in an
inconsistent state of still being open and active.

Modifications:

Move the satisfaction of the promise to after the channel cleanup logic
runs.

Result:

Listeners attached to the future that resulted in a Failed write will
see the stream channel in the correct state.

Motivation:

a214f2eb96 Remove id from DnsQueryContextManager whenever the promise is fullfilled.
Motivation:

We did not handle the case when the query was cancelled which could lead to an exhausted id space. Beside this we did not not cancel the timeout on failed promises.

Modifications:

- Do the removal of the id from the manager in a FutureListener so its handled in all cases.
- Cancel the timeout whenever the original promise was full-filled.

Result:

f164759ea3 Support composite buffer creation without array alloc and copy
Motivation:

Unpooled.unmodifiableBuffer() is currently used to efficiently write
arrays of ByteBufs via FixedCompositeByteBuf, but involves an allocation
and content-copy of the provided ByteBuf array which in many (most?)
cases shouldn't be necessary.

Modifications:

Modify the internal FixedCompositeByteBuf class to support wrapping the
provided ByteBuf array directly. Control this behaviour with a
constructor flag and expose the "unsafe" version via a new
Unpooled.wrappedUnmodifiableBuffer(ByteBuf...) method.

Result:

Less garbage on IO paths. I would guess pretty much all existing usage
of unmodifiableBuffer() could use the copy-free version but assume it's
not safe to change its default behaviour.

06f3574e46 Don't calculate max direct memory twice in PlatformDependent
Motivation:

I'm not sure if trivial changes like this are interesting :-) But I
noticed that the PlatformDependent.maxDirectMemory0() method is called
twice unnecessarily during static initialization (on the default path at
least).

Modifications:

Use constant MAX_DIRECT_MEMORY already set to the same value instead of
calling maxDirectMemory0() again.

Result:

A surely imperceivable reduction in operations performed at startup.

8f01259833 HpackDecoder treats invalid pseudo-headers as stream level errors
Motivation:

The HTTP/2 spec dictates that invalid pseudo-headers should cause the
request/response to be treated as malformed (8.1.2.1), and the recourse
for that is to treat the situation as a stream error of type
PROTOCOL_ERROR (8.1.2.6). However, we're treating them as a connection
error with the connection being immediately torn down and the HPACK
state potentially being corrupted.

Modifications:

The HpackDecoder now throws a StreamException for validation failures
and throwing is deffered until the end of of the decode phase to ensure
that the HPACK state isn't corrupted by returning early.

Result:

Behavior more closely aligned with the HTTP/2 spec.

Fixes #8043.

* Implementation of WebSocketUtil/randomBytes changed to nextBytes method

* PlatformDependet.threadLocalRandom is used instead of Math.random to improve efficiency

* Added test cases to check random numbers generator

* To ensure corretness, we now assert that min < max when generating random number

9ffdec302e Make results of handler proxy tests reproducible
Motivation:

`ProxyHandlerTest` relies on random values to run tests: first to
shuffle collection of test items and lately to set configuration
flag for `AUTO_READ`. While the purpose of randomization is clear,
it's still impossible to reproduce the same sequence of test cases
when something went wrong. For `AUTO_READ` it's even impossible
to tell what flag was set when the particular test failed.

Modifications:

* Test runner now log seed values that was used for shuffling,
  so you can take one and put in your tests to "freeze" them
  while debugging (pretty common approach with randomized tests)

* `SuccessItemTest` is split into 2 different use cases:
  for AUTO_READ flag set to "on" and "off"

Result:

You can reproduce specific tests results now.

0337ecdcc8 Allow to cache keymaterial when using OpenSSL
Motiviation:

During profiling it showed that a lot of time during the handshake is spent by parsing the key / chain over and over again. We should cache these parsed structures if possible to reduce the overhead during handshake.

Modification:

- Use new APIs provided by https://github.com/netty/netty-tcnative/pull/360.
- Introduce OpensslStaticX509KeyManagerFactory which allows to wrap another KeyManagerFactory and caches the key material provided by it.

Result:

In benchmarks handshake times have improved by 30 %.

4a8d3a274c Including the setup code in the benchmark method to avoid JMH Invocation level hiccups.
Motivation:

The usage of Invocation level for JMH fixture methods (setup/teardown) inccurs in a significant overhead
in the benchmark time (see org.openjdk.jmh.annotations.Level documentation).

In the case of CodecInputListBenchmark, benchmarks are far too small (less than 50ns) and the Invocation
level setup offsets the measurement considerably.
On such cases, the recommended fix patch is to include the setup/teardown code in the benchmark method.

Modifications:

Include the setup/teardown code in the relevant benchmark methods.
Remove the setup/teardown methods from the benchmark class.

Result:

We run the entire benchmark 10 times with default parameters we observed:
- ArrayList benchmark affected directly by JMH overhead is now from 15-80% faster.
- CodecList benchmark is now 50% faster than original (even with the setup code being measured).
- Recyclable ArrayList is ~30% slower.
- All benchmarks have significant different means (ANOVA) and medians (Moore)

Mode: Throughput (Higher the better)
