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.

05e5ab1ecb Store NativeDatagramPacketArray directly in the EpollEventLoop
Motivation:

We can store the NativeDatagramPacketArray directly in the EpollEventLoop. This removes the need of using FastThreadLocal.

Modifications:

- Store NativeDatagramPacketArray directly in the EpollEventLoop (just as we do with IovArray as well).

Result:

Less FastThreadLocal usage and more consistent code.

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:

Fixes https://github.com/netty/netty/issues/8013.

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.

5e42e758be Also remove the id from the DnsQueryContextManager if query fails due parent Channel activation error.
Motivation:

Whenever we fail the query we should also remove the id from the DnsQueryContextManager.

Modifications:

Remove the id from the DnsQueryContextManager if we fail the query because the channel failed to become active.

Result:

More correct code.

00afb19d7a Get rid of deprecated SslContext methods in handler-proxy tests
Motivation:

ProxyHandlerTest package uses deprecated methods SslContext.newServerContext and
SslContext.newClientContext.

Modifications:

SslContextBuilder is used to build server and client SslContext.

Result:

fa4e28ba1c Fix random number generators in WebSocketUtil
Motivation:

Implementation of WebSocketUtil/randomNumber is incorrect and might violate
the API returning values > maximum specified.

Modifications:

* WebSocketUtil/randomNumber is reimplemented, the idea of the solution described
  in the comment in the code

* 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

Result:

WebSocketUtil/randomNumber always produces correct result.

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)

cb420a9ffc 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 impact in
in the benchmark time (see org.openjdk.jmh.annotations.Level documentation).

When the benchmark and the setup/teardown is too small (less than a milisecond) the Invocation level might saturate the system with
timestamp requests and iteration synchronizations which introduce artificial latency, throughput, and scalability bottlenecks.

In the HeadersBenchmark, all benchmarks take less than 100ns and the Invocation level setup offsets the measurement considerably.
As fixture methods is defined for the entire class, this overhead also impacts every single benchmark in this class, not only
the ones that use the emptyHttpHeaders object (cleaned in the setup).

The recommended fix patch here is to include the setup/teardown code in the benchmark where the object is used.

Modifications:

Include the setup/teardown code in the relevant benchmark methods.
Remove the setup/teardown method of Invocation level from the benchmark class.

Result:

We run all benchmarks from HeadersBenchmark 10 times with default parameter, we observe:
- Benchmarks that were not directly affected by the fix patch, improved execution time.
    For instance, http2Remove with (exampleHeader = THREE) had its median reported as 2x faster than the original version.
- Benchmarks that had the setup code inserted (eg. http2AddAllFastest) did not suffer a significant punch in the execution time,
as the benchmarks are not dominated by the clear().

Environment:
Tests run on a Computational server with CPU: E5-1660-3.3GHZ  (6 cores + HT), 64 GB RAM.

8687e1eeed Don't fail the deregistration promise in Http2MultiplexCodec
Motivation:

We deviate from the AbstractChannel implementation on deregistration by
failing the provided promise if the channel is already deregistered. In
contrast, AbstractChannel will always set the promise to successfully
done.

Modification:

Change the
Http2MultiplexCodec.DefaultHttp2StreamChannel.Http2ChannelUnsafe to
always set the promise provided to deregister as done as is the
case in AbstractChannel.

4c709be1ab Print correct invalid character after unwrapping value in CookieEncoder
Motivation:

If a wrapped cookie value with an invalid charcater is passed to the strict
encoder, an exception is thrown on validation but the error message contains
a character at the wrong position.

Modifications:

Print `unwrappedValue.charAt(pos)` instead of `value.charAt(pos)`.

Result:

The exception indicates the correct invalid character in the unwrapped cookie.

9b95b8ee62 Reduce array allocations during CompositeByteBuf construction
Motivation:

Eliminate avoidable backing array reallocations when constructing
composite ByteBufs from existing buffer arrays/Iterables. This also
applies to the Unpooled.wrappedBuffer(...) methods.

Modifications:

Ensure the initial components ComponentList is sized at least as large
as the provided buffer array/Iterable in the CompositeByteBuffer
constructors.

In single-arg Unpooled.wrappedBuffer(...) methods, set maxNumComponents
to the count of provided buffers, rather than a fixed default of 16. It
seems likely that most usage of these involves wrapping a list without
subsequent modification, particularly since they return a ByteBuf rather
than CompositeByteBuf. If a different/larger max is required there are
already the wrappedBuffer(int, ...) variants.

In fact the current behaviour could be considered inconsistent - if you
call Unpooled.wrappedBuffer(int, ByteBuf) with a single buffer, you
might expect to subsequently be able to add buffers to it (since you
specified a max related to consolidation), but it will in fact return
just a slice of the provided ByteBuf.

Result:

Fewer and smaller allocations in some cases when using CompositeByteBufs
or Unpooled.wrappedBuffer(...).

12f6500a4f Epoll and Kqueue shouldn't read by default (#8024)
Motivation:
Epoll and Kqueue channels have internal state which forces
a single read operation after channel construction. This
violates the Channel#read() interface which indicates that
data shouldn't be delivered until this method is called.
The behavior is also inconsistent with the NIO transport.

Modifications:
- Epoll and Kqueue shouldn't unconditionally read upon
initialization, and instead should rely upon Channel#read()
or auto_read.

Result:
Epoll and Kqueue are more consistent with NIO.

c7c8e6a3ec Defer channelInactive and channelUnregistered events in Http2MultiplexCodec (#8021)
Motivation:

There is an inconsistency between the order of events in the
StreamChannel implementation in Http2MultiplexCodec and other Channel
implementations that extend AbstractChannel where channelInactive and
channelUnregistered events are not performed 'later'. This can cause an
unexected order of events for ChannelHandler implementations that call
Channel.close() in response to some event.

Modification:

The Http2MultiplexCodec.DefaultHttp2StreamChannel.Http2ChannelUnsafe was
modified to bounce the deregistration and channelInactive events through
the parent channels EventLoop.

Result:

Stream events are now in the proper order.

35215309b9 Make UnpooledHeapByteBuf array methods protected (#8015)
Motivation:

Currently there is not a clear way to provide a byte array to a netty
ByteBuf and be informed when it is released. This is a would be a
valuable addition for projects that integrate with netty but also pool
their own byte arrays.

Modification:

Modified the UnpooledHeapByteBuf class so that the freeArray method is
protected visibility instead of default. This will allow a user to
subclass the UnpooledHeapByteBuf, provide a byte array, and override
freeArray to return the byte array to a pool when it is called.
Additionally this makes this implementation equivalent to
UnpooledDirectByteBuf (freeDirect is protected).

Additionally allocateArray is also made protect to provide another override
option for subclasses.

Result:

Users can override UnpooledHeapByteBuf#freeArray and
UnpooledHeapByteBuf#allocateArray.

400ca87334 Provide an API for controlling and h2c upgrade response stream in Http2MultiplexCodec (#7968)
Motivation:

Http2MultiplexCodec doesn't currently have an API for using the response
of a h2c upgrade request.

Modifications:

Add a new API to the Http2MultiplexCodecBuilder which allows for setting
an upgrade handler and wire it into the Http2MultiplexCodec
implementation.

Result:

When using the Http2MultiplexCodec with h2c upgrades the upgrade handler
will get added to the Http2StreamChannel which represents the
half-closed (local) response of stream 1. It is then up to the user to
manage the transition from the IO channel pipeline configuration
necessary for making the h2c upgrade request to a form where it can read
the response from the new stream channel.

Fix race in SslHandlerTest that could lead to NPE. (#7989)

48911e0b63 Set (and override) websocket handshake headers after custom headers (#7975)
Motivation:

Currently, when passing custom headers to a WebSocketClientHandshaker,
if values are added for headers that are reserved for use in the
websocket handshake performed with the server, these custom values can
be used by the server to compute the websocket handshake challenge. If
the server computes the response to the challenge with the custom header
values, rather than the values computed by the client handshaker, the
handshake may fail.

Modifications:

Update the client handshaker implementations to add the custom header
values first, and then set the reserved websocket header values.

Result:

Reserved websocket handshake headers, if present in the custom headers
passed to the client handshaker, will not be propagated to the server.
Instead the client handshaker will propagate the values it generates.

Fixes #7973.

b53cf045a7 SelectedSelectionKeySet should only be created if the set can be instrumented
Motivation:

If we can not replace the internal used Set of the Selector there is no need to create an SelectedSelectionKeySet instance.

Modification:

Only create SelectedSelectionKeySet if we will replace the internal set.

Result:

Less object creation in some cases and cleaner code.

Allow to schedule tasks up to Long.MAX_VALUE (#7972)
Motivation:

We should allow to schedule tasks with a delay up to Long.MAX_VALUE as we did pre 4.1.25.Final.

Modifications:

Just ensure we not overflow and put the correct max limits in place when schedule a timer. At worse we will get a wakeup to early and then schedule a new timeout.

Result:

Fixes https://github.com/netty/netty/issues/7970.

Ignore some test-flakiness when using Java11+ due outstanding Java11 bug. (#7984)
Motivation:

Java11 disallow draining any remaining bytes from the socket if a write causes a connection reset. This should be completely safe to do. At the moment if a write is causing a connection-reset you basically loose all the pending bytes that are sitting on the socket and are waiting to be read.

This happens because SocketOutputStream.write(…) may call AbstractPlainSocketImpl.setConnectionReset(…). Once this method is called any read(…) call will just throw a SocketException without even attempt to read any remaining data.

This is related:

 - http://mail.openjdk.java.net/pipermail/net-dev/2018-May/011511.html

Modifications:

Tolarate if remaining bytes could not be read when using OIO.

Result:

Be able to build Netty and run testsuite while using Java11

Allow to test with boringssl-static and drop into shell (#7980)
Motivation:

We also need to run our tests while using boringssl-static to ensure everything works when using it. Beside this its sometimes useful to be able to just get a shell and so interactive work in the docker instance.

Modifications:

- Add configs for shell
- Add configs for testing with boringssl-static
- Ensure we not share .m2 when running tests

Result:

More complete docker setup.

Don't trim stacktrace for exceptions when running mvn test (#7981)
Motivation:

The maven surefire plugin will trim stacktraces by default which makes these kind of use-less when trying to understand why an test failed because one was thrown.

Modifications:

Configure the plugin to not trim the stacktrace.

Result:

Easier to debug test-failures.

Correctly let Http2UnkownFrame extend HttpStreamFrame and so be usable with Http2MultiplexCodec. (#7976)
Motivation:

This is a followup for #7860. In the fix for #7860 we only partly fixed the problem as Http2UnknownFrame did not correctly extend HttpStreamFrame and so only worked when using the Http2FrameCodec. We need to have it extend HttpStreamFrame as otherwise Http2MultiplexCodec will reject to handle it correctly.

Modifications:

- Let Http2UnknownFrame extend HttpStreamFrame
- Add unit tests for writing and reading Http2UnkownFrame instances when the Http2MultiplexCodec is used.

Result:

Fixes https://github.com/netty/netty/issues/7969.

9a3311506e Run the WebSocketClientHandshaker08Test on the 08 implementation (#7974)
Motivation:

The websockets abstract test suite does not run against the 08
implementation in the 08 version of the test suite.

Modifications:

Update the WebSocketClientHandshaker08Test to instantiate a new
WebSocketClientHandshaker08 rather than an 07 handshaker.

Result:

The WebSocketClientHandshaker08Test now tests the 08 implementation.
