Add support for Unix domain datagram sockets when using native epoll/kqueue transport (#11476)
Motivation:

There are use cases when Unix domain datagram sockets are needed for communication.
This PR adds such support for Epoll/KQueue.

Modification:

- Expose Channel, Config and Packet interfaces/classes for Unix domain datagram sockets.
All interfaces/classes are in `transport-native-unix-common` module in order to be available
for KQueue and Epoll implementations
- Add JNI code for Unix domain datagram sockets
- Refactor `DatagramUnicastTest` so that it can be used for testing also Unix domain datagram sockets
- Add Unix domain datagram sockets implementation for KQueue transport
- Add Unix domain datagram sockets implementation for Epoll transport

Result:

Fixes #6737

Remove Void*Promise (#11348)
Motivation:

Sometime in the past we introduced the concept of Void*Promise. As it turned out this was not a good idea at all as basically each handler in the pipeline need to be very careful to correctly handle this. We should better just remove this "optimization".

Modifications:

- Remove Void*Promise and all the related APIs
- Remove tests which were related to Void*Promise

Result:

Less error-prone API

Migrate testsuite, transport-native-epoll, transport-native-kqueue, and transport-native-unix-common-tests tests to JUnit 5 (#11320)
Motivation:

JUnit 5 is more expressive, extensible, and composable in many ways, and it's better able to run tests in parallel.

Modifications:

Use JUnit5 in tests

Result:

f2127d7963 Ensure we can load the native library or fail the build (#11262)
Motivation:

We used assumeTrue(...) in some places before to detect if we could load the native library but this could lead to the sitation that we not notice if we break native loading.

Modifications:

Always fail if we cant load the native library

Result:

Ensure we not cause any regression in the native loading code in the future

b9685a63de Use PlatformDependent#normalizedOs() instead of reading os.name prop (#11239)
Motivation:

`PlatformDependent#normalizedOs()` already caches normalized variant of
the value of `os.name` system property. Instead of inconsistently
normalizing it in every case, use the utility method.

Modifications:

- `PlatformDependent`: `isWindows0()` and `isOsx0()` use `NORMALIZED_OS`;
- `PlatformDependent#normalizeOs(String)` define `darwin` as `osx`;
- `OpenSsl#loadTcNative()` does not require `equalsIgnoreCase` bcz `os`
is already normalized;
- Epoll and KQueue: `Native#loadNativeLibrary()` use `normalizedOs()`;
- Use consistent `Locale.US` for lower case conversion of `os.name`;
- `MacOSDnsServerAddressStreamProvider#loadNativeLibrary()` uses
`PlatformDependent.isOsx()`;

Result:

Consistent approach for `os.name` parsing.

968dfbb378 Preload classes before calling native OnLoad function to prevent clas… (#11215)
Motivation:

It turns out it is quite easy to cause a classloader deadlock in more recent java updates if you cause classloading while you are in native code. Because of this we should just workaround this issue by pre-load all the classes that needs to be accessed in the OnLoad function.

Modifications:

- Preload all classes that would otherwise be loaded by native OnLoad functions.

Result:

Workaround for https://github.com/netty/netty/issues/11209 and https://bugs.openjdk.java.net/browse/JDK-8266310

bb97d1699d AbstractKQueueChannel#writeFilter is invoked with the correct boolean depending on the ChannelOutboundBuffer state (#11128)
Motivation:

This is a regression caused by #11086

Modifications:

AbstractKQueueChannel#writeFilter should be invoked with `!in.isEmpty()`
- false - all messages are written
- true - there are still messages to be written

Result:

AbstractKQueueChannel#writeFilter is invoked with the correct boolean depending on the ChannelOutboundBuffer state

8d483b58b3 Use netty-jni-util 0.0.3.Final
netty-jni-util 0.0.2.Final is incompatible with static linking. Before
the netty-jni-util dependency was introduced netty-tcnative supported
static linking via NETTY_BUILD_STATIC. netty-jni-util 0.0.3.Final adds
static linking compatibility.

Modifications:

Bump netty-jni-util to version 0.0.3.Final and update to its new API
which requires the caller to manage packagePrefix.

Result:

Using latest version of netty-jni-util and restored static linking
compatibility.

163b2b659c Continue reading when the number of bytes is less then the configured… (#11089)
... number of bytes when using DatagramChannels

Motivation:

In our FixedRecvByteBufAllocator we dont continue to read if the number of bytes is less then what was configured. This is correct when using it for TCP but not when using it for UDP. When using UDP the number of bytes is the maximum of what we want to support but we often end up processing smaller datagrams in general. Because of this we should use contineReading(UncheckedBooleanSupplier) to determite if we should continue reading

Modifications:

- use contineReading(UncheckedBooleanSupplier) for DatagramChannels

Result:

Read more then once in the general case for DatagramChannels with the default config

817052d019 Allow to configure the maximum number of message to write per eventloop (#11086)
Motivation:

Allow to configure the maximum number of messages to write per eventloop run. This can be useful to ensure we read data in a timely manner and not let writes dominate the CPU time. This is especially useful in protocols like QUIC where you need to read "fast enough" as otherwise you may not read the ACKs fast enough.

Modifications:

- Add new ChannelOption / config that allows to limit the number of messages to write per eventloop run.
- Respect this setting for DatagramChannels

Result:

Reduce the risk of having WRITES block the processing of other events in a timely manner

Introduce ByteBufConvertible interface (#11036)
Motivation:
To make it possible to experiment with alternative buffer implementations, we need a way to abstract away the concrete buffers used throughout most of the Netty pipelines, while still having a common currency for doing IO in the end.

Modification:
- Introduce an ByteBufConvertible interface, that allow arbitrary objects to convert themselves into ByteBuf objects.
- Every place in the code, where we did an instanceof check for ByteBuf, we now do an instanceof check for ByteBufConvertible.
- ByteBuf itself implements ByteBufConvertible, and returns itself from the asByteBuf method.

Result:
It is now possible to use Netty with alternative buffer implementations, as long as they can be converted to ByteBuf.
This has been verified elsewhere, with an alternative buffer implementation.

a7e8a33833 Ensure native methods for unix-native-common are only registered once. (#10932)
Motiviation:

We need to ensure we only register the methods for unix-native-common once as otherwise it may have strange side-effects.

Modifications:

- Add extra method that should be called to signal that we need to register the methods. The registration will only happen once.
- Adjust code to make use of it.

Result:

No more problems due incorrect registration of these methods.

475f20aa0f Use netty-jni-util and so remove a lot of duplication (#10735)
Motivation:

We had a lot of duplication in our jni code which was mostly due macros but also related to how we support shading. By using netty-jni-util we can share all the code between netty and netty-tcnative ( and possible other jni based netty projects in the future).

Modifications:

- Use netty-jni-util and re-use its macros / functions
- Remove duplicated code
- Adjust build files

Result:

Less code duplication for JNI

436e47f12b Unregister all native methods on unload for kqueue (#10738)
Motivation:

31ffe11e47 Unregister all previous registered native methods if loading of native code fails… (#10719)
Motivation:

It's important to unload all previous registered native methods when there is a failure during loading the native lib. Failing to do so may lead to an "invalid state" and so may segfault the JVM when trying to call a native method that was previous loaded.

This was observed when two versions of netty-tcnative were on the classpath which had different requirements in terms of linking.

Something like this was reported in he hs log:

```
Instructions: (pc=0x0000000116413bf0)
0x0000000116413bd0:
[error occurred during error reporting (printing registers, top of stack, instructions near pc), id 0xb]

Register to memory mapping:

RAX=0x0000000116413bf0 is an unknown value
RBX={method} {0x000000011422e708} 'aprMajorVersion' '()I' in 'io/netty/internal/tcnative/Library'
RCX=0x000000000000000a is an unknown value
RDX=0x000000000000000a is an unknown value
```

Modifications:

- Unregister previous registered native methods on failure
- Unregister previous registered native methods on on unload of the native lib

Result:

No more segfault caused by invalid state when loading of the native lib fails in between. In this case the user will receive an error now like:

5ad80c5887 Allow EventLoops to rethrow Error (#10694)
Motivation:

Thread.stop() works by producing a ThreadDeath error in the target thread. EventLoops swallow all Throwables, which makes them effectively unkillable. This is effectively a memory leak, for our application. Beside this we should also just regrow all `Error` as there is almost no way to recover.

Modification:

Edit the EventLoops that swallow Throwables to instead rethrow Error.

Result:

`EventLoop` can crash if `Error` is thrown

b8ae2a2af4 Enable nohttp check during the build (#10708)
Motivation:

HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.

Modifications:

- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
  that don't support HTTPS or that are not reachable

Result:

- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
  the code.

Add a build profile for JDK 16 (#10675)
Motivation:
Java 16 will come around eventually anyway, and this makes it easier for people to experiment with Early Access builds.

Modification:
- Added Maven profiles for JDK 16 to relevant pom files.
- Removed the `--add-exports java.base/sun.security.x509=ALL-UNNAMED` argument when running tests; we've not needed it since the Java11-as-baseline PR landed.

Result:
Netty now builds on JDK 16 pre-releases (provided they've not broken compatibility in some way).

223422cea3 Fix #10434 OutOfDirectMemoryError causes cpu load too high and socket is full (#10457)
Motivation:

When we were using the netty http protocol, OOM occurred, this problem has been in 4.1.51.Final Fix [# 10424](https://github.com/netty/netty/issues/10424), even if OOM is up, the service will still receive new connection events, will occur again OOM and eventually cause the connection not to be released.

code `byteBuf = allocHandle.allocate(allocator);`

Modification:

I fail to create buffer when I try to receive new data, i determine if it is OOM then the close read event releases the connection.
```java
        if (close || cause instanceof OutOfMemoryError || cause instanceof IOException) {
            closeOnRead(pipeline);
        }

Fix event loop shutdown timing fragility (#9639)
Motivation

The current event loop shutdown logic is quite fragile and in the
epoll/NIO cases relies on the default 1 second wait/select timeout that
applies when there are no scheduled tasks. Without this default timeout
the shutdown would hang indefinitely.

The timeout only takes effect in this case because queued scheduled
tasks are first cancelled in
SingleThreadEventExecutor#confirmShutdown(), but I _think_ even this
isn't robust, since the main task queue is subsequently serviced which
could result in some new scheduled task being queued with much later
deadline.

It also means shutdowns are unnecessarily delayed by up to 1 second.

Modifications

- Add/extend unit tests to expose the issue
- Adjust SingleThreadEventExecutor shutdown and confirmShutdown methods
to explicitly add no-op tasks to the taskQueue so that the subsequent
event loop iteration doesn't enter blocking wait (as looks like was
originally intended)

Results

Faster and more robust shutdown of event loops, allows removal of the default wait timeout.
This is a port of https://github.com/netty/netty/pull/9616

15eef2425a Cleanup JNI code to always correctly free memory when loading fails and also correctly respect out of memory in all cases (#9596)
Motivation:

At the moment we not consistently (and also not correctly) free allocated native memory in all cases during loading the JNI library. This can lead to native memory leaks in the unlikely case of failure while trying to load the library.

Beside this we also not always correctly handle the case when a new java object can not be created in native code because of out of memory.

Modification:

- Copy some macros from netty-tcnative to be able to handle errors in a more easy fashion
- Correctly account for New* functions to return NULL
- Share code

Result:

More robust and clean JNI code

bf52f39e59 Allow domain sockets to configure SO_SNDBUF and SO_RCVBUF (#9584)
Motivation:

Running tests with a `KQueueDomainSocketChannel` showed worse performance than an `NioSocketChannel`. It turns out that the default send buffer size for Nio sockets is 64k while for KQueue sockets it's 8k. I verified that manually setting the socket's send buffer size improved perf to expected levels.

Modification:

Plumb the `SO_SNDBUF` and `SO_RCVBUF` options into the `*DomainSocketChannelConfig`.

Result:

Can now configure send and receive buffer sizes for domain sockets.

Motivation:

We should correctly reset the cached local and remote address when a Channel.disconnect() is called and the channel has a notion of disconnect vs close (for example DatagramChannel implementations).

Modifications:

- Correctly reset cached kicak abd remote address
- Update testcase to cover it and so ensure all transports work in a consistent way

19a12fba4c Correctly handle IPV6-mapped-IPV4 addresses in native code when receiving datagrams (#9560)
Motivation:

291f80733a introduced a change to use a byte[] to construct the InetAddress when receiving datagram messages to reduce the overhead. Unfortunally it introduced a regression when handling IPv6-mapped-IPv4 addresses and so produced an IndexOutOfBoundsException when trying to fill the byte[] in native code.

Modifications:

- Correctly use the offset on the pointer of the address.
- Add testcase
- Make tests more robust and include more details when the test fails

Result:

No more IndexOutOfBoundsException

68e49af483 Fix native-build/target/lib wanted but build in native-build/target/lib64 (#9410)
Motivation:

On openSUSE (probably more), 64 bit builds use lib64, e.g. /usr/lib64, and
configure picks this up and builds the native library in
native-build/target/lib64 where maven is not looking.

Modifications:

Explicitly specify --libdir=${project.build.directory}/native-build/target/lib
during configuration.

Result:

Maven uses the correct lib directory.

f85583047e KQueueEventLoop | EpollEventLoop may incorrectly update registration when FD is reused.
Motivation:

The current KQueueEventLoop implementation does not process concurrent domain socket channel registration/unregistration in the order they actual
happen since unregistration are delated by an event loop task scheduling. When a domain socket is closed, it's file descriptor might be reused
quickly and therefore trigger a new channel registration using the same descriptor.

Consequently the KQueueEventLoop#add(AbstractKQueueChannel) method will overwrite the current inactive channels having the same descriptor
and the delayed KQueueEventLoop#remove(AbstractKQueueChannel) will remove the active channel that replaced the inactive one.

As active channels are registered, events for this file descriptor won't be processed anymore and the channels will never be closed.

The same problem can also happen in EpollEventLoop. Beside this we also may never remove the AbstractEpollChannel from the internal map
when it is unregistered which will prevent it from be GC'ed

Modifications:

- Change logic of native KQueue and Epoll implementations to ensure we correctly handle the case of FD reuse
- Only try to update kevent / epoll if the Channel is still open (as otherwise it will be handled by kqueue / epoll itself)
- Correctly remove AbstractEpollChannel from internal map in all cases
- Make implementation of closeAll() consistent for Epoll and KQueueEventLoop

Result:

KQueue and Epoll native transports correctly handle FD reuse

ed61e5f543 Only use static Exception instances when we can ensure addSuppressed … (#9152)

7f79182c82 Have (Epoll|KQueue)RecvByteAllocatorHandle extend DelegatingHandle (#9060)
Motivation

These implementations delegate most of their methods to an existing Handle and previously extended RecvByteBufAllocator.DelegatingHandle. This was reverted in #6322 with the introduction of ExtendedHandle but it's not clear to me why it needed to be - the code looks a lot cleaner.

Modifications

Have (Epoll|KQueue)RecvByteAllocatorHandle extend DelegatingHandle again, while still implementing ExtendedHandle.

Result

9ef5c0946a Add IPv6 multicast test to testsuite (#9037)
Motivation:

We currently only cover ipv4 multicast in the testsuite but we should also have tests for ipv6.

Modifications:

- Add test for ipv6
- Ensure we only try to run multicast test for ipv4 / ipv6 if the loopback interface supports it.

Result:

Better test coverage

135c33b478 Correctly handle overflow in Native.kevent(...) when EINTR is detected (#9024)
Motivation:
When kevent(...) returns with EINTR we do not correctly decrement the timespec
structure contents to account for the time duration. This may lead to negative
values for tv_nsec which will result in an EINVAL and raise an IOException to
the event loop selection loop.

Modifications:
Correctly calculate new timeoutTs when EINTR is detected

Result:
Fixes #9013.

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.

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'.

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

Result:

Cleanup class-hierarchy and make things a bit more flexible.

2720a40a20 Remove --add-opens=java.base/java.nio=ALL-UNNAMED when running tests as it is not needed anymore since a long time (#8934)
Motivation:

At some point we needed --add-opens=java.base/java.nio=ALL-UNNAMED to run our native tests but this is not true anymore.

Modifications:

Remove --add-opens=java.base/java.nio=ALL-UNNAMED when running native tests.

Result:

Remove obsolate jvm arg.
