5dacc5f3da Resolve the pid field in PeerCredentials of KQueueDomainSocketChannels. (#9219)
Motivation:

This resolves a TODO from the initial transport-native-kqueue implementation, supplying the user with the pid of the local peer client/server process.

Modification:

Inside netty_kqueue_bsdsocket_getPeerCredentials, Call getsockopt with LOCAL_PEERPID and pass it to PeerCredentials constructor.
Add a test case in KQueueSocketTest.

Result:

PeerCredentials now have pid field set. Fixes https://github.com/netty/netty/issues/9213

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)
Motivation:

OOME is occurred by increasing suppressedExceptions because other libraries call Throwable#addSuppressed. As we have no control over what other libraries do we need to ensure this can not lead to OOME.

Modifications:

Only use static instances of the Exceptions if we can either dissable addSuppressed or we run on java6.

Result:

Not possible to OOME because of addSuppressed. Fixes https://github.com/netty/netty/issues/9151.

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

Less code.

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:

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.

106bd0c091 DefaultFileRegion.transferTo with invalid count may cause busy-spin (#8885)
Motivation:

`DefaultFileRegion.transferTo` will return 0 all the time when we request more data then the actual file size. This may result in a busy spin while processing the fileregion during writes.

Modifications:

- If we wrote 0 bytes check if the underlying file size is smaller then the requested count and if so throw an IOException
- Add DefaultFileRegionTest
- Add a test to the testsuite

Result:

b817de97e0 Don't deregister Channel as part of closing it when using native kqueue transport (#8881)
Motivation:

In https://github.com/netty/netty/pull/8665 we changed how we handle the registration of Channels to KQueue but missed to removed some code which would deregister the Channel before it actual closed the underlying socket. This could lead to have events triggered still while not have a mapping to the Channel anymore.

Modifications:

Remove deregister call during socket closure.

Result:

Fixes https://github.com/netty/netty/issues/8849.

b9d277dbcb Support using an Executor to offload blocking / long-running tasks wh… (#8847)
Motivation:

The SSLEngine does provide a way to signal to the caller that it may need to execute a blocking / long-running task which then can be offloaded to an Executor to ensure the I/O thread is not blocked. Currently how we handle this in SslHandler is not really optimal as while we offload to the Executor we still block the I/O Thread.

Modifications:

- Correctly support offloading the task to the Executor while suspending processing of SSL in the I/O Thread
- Add new methods to SslContext to specify the Executor when creating a SslHandler
- Remove @deprecated annotations from SslHandler constructor that takes an Executor
- Adjust tests to also run with the Executor to ensure all works as expected.

Result:

Be able to offload long running tasks to an Executor when using SslHandler. Partly fixes https://github.com/netty/netty/issues/7862 and https://github.com/netty/netty/issues/7020.

99face616a Reduce GC produced by native DatagramChannel implementations when in connected mode. (#8806)
Motivation:

In the native code EpollDatagramChannel / KQueueDatagramChannel creates a DatagramSocketAddress object for each received UDP datagram even when in connected mode as it uses the recvfrom(...) / recvmsg(...)  method. Creating these is quite heavy in terms of allocations as internally, char[], String, Inet4Address, InetAddressHolder, InetSocketAddressHolder, InetAddress[], byte[] objects are getting generated when constructing the object. When in connected mode we can just use regular read(...) calls which do not need to allocate all of these.

Modifications:

- When in connected mode use read(...) and NOT recvfrom(..) / readmsg(...) to reduce allocations when possible.
- Adjust tests to ensure read works as expected when in connected mode.

Result:

Less allocations and GC when using native datagram channels in connected mode. Fixes https://github.com/netty/netty/issues/8770.

Decouple EventLoop details from the IO handling for each transport to… (#8680)
* Decouble EventLoop details from the IO handling for each transport to allow easy re-use of code and customization

Motiviation:

As today extending EventLoop implementations to add custom logic / metrics / instrumentations is only possible in a very limited way if at all. This is due the fact that most implementations are final or even package-private. That said even if these would be public there are the ability to do something useful with these is very limited as the IO processing and task processing are very tightly coupled. All of the mentioned things are a big pain point in netty 4.x and need improvement.

Modifications:

This changeset decoubled the IO processing logic from the task processing logic for the main transport (NIO, Epoll, KQueue) by introducing the concept of an IoHandler. The IoHandler itself is responsible to wait for IO readiness and process these IO events. The execution of the IoHandler itself is done by the SingleThreadEventLoop as part of its EventLoop processing. This allows to use the same EventLoopGroup (MultiThreadEventLoupGroup) for all the mentioned transports by just specify a different IoHandlerFactory during construction.

Beside this core API change this changeset also allows to easily extend SingleThreadEventExecutor / SingleThreadEventLoop to add custom logic to it which then can be reused by all the transports. The ideas are very similar to what is provided by ScheduledThreadPoolExecutor (that is part of the JDK). This allows for example things like:

  * Adding instrumentation / metrics:
    * how many Channels are registered on an SingleThreadEventLoop
    * how many Channels were handled during the IO processing in an EventLoop run
    * how many task were handled during the last EventLoop / EventExecutor run
    * how many outstanding tasks we have
    ...
    ...
  * Implementing custom strategies for choosing the next EventExecutor / EventLoop to use based on these metrics.
  * Use different Promise / Future / ScheduledFuture implementations
  * decorate Runnable / Callables when submitted to the EventExecutor / EventLoop

As a lot of functionalities are folded into the MultiThreadEventLoopGroup and SingleThreadEventLoopGroup this changeset also removes:

  * AbstractEventLoop
  * AbstractEventLoopGroup
  * EventExecutorChooser
  * EventExecutorChooserFactory
  * DefaultEventLoopGroup
  * DefaultEventExecutor
  * DefaultEventExecutorGroup

Result:

Fixes https://github.com/netty/netty/issues/8514 .

Make it possible to use a wrapped EventLoop with a Channel (#8677)
Motiviation:

Because of how we implemented the registration / deregistration of an EventLoop it was not possible to wrap an EventLoop implementation and use it with a Channel.

Modification:

- Introduce EventLoop.Unsafe which is responsible for the actual registration.
- Move validation of EventLoop / Channel combo to the EventLoop
- Add unit test that verifies that wrapping works

Result:

Be able to wrap an EventLoop and so add some extra functionality.

Tighten contract between Channel and EventLoop by require the EventLoop on Channel construction. (#8587)
Motivation:

At the moment it’s possible to have a Channel in Netty that is not registered / assigned to an EventLoop until register(...) is called. This is suboptimal as if the Channel is not registered it is also not possible to do anything useful with a ChannelFuture that belongs to the Channel. We should think about if we should have the EventLoop as a constructor argument of a Channel and have the register / deregister method only have the effect of add a Channel to KQueue/Epoll/... It is also currently possible to deregister a Channel from one EventLoop and register it with another EventLoop. This operation defeats the threading model assumptions that are wide spread in Netty, and requires careful user level coordination to pull off without any concurrency issues. It is not a commonly used feature in practice, may be better handled by other means (e.g. client side load balancing), and therefore we propose removing this feature.

Modifications:

- Change all Channel implementations to require an EventLoop for construction ( + an EventLoopGroup for all ServerChannel implementations)
- Remove all register(...) methods from EventLoopGroup
- Add ChannelOutboundInvoker.register(...) which now basically means we want to register on the EventLoop for IO.
- Change ChannelUnsafe.register(...) to not take an EventLoop as parameter (as the EventLoop is supplied on custruction).
- Change ChannelFactory to take an EventLoop to create new Channels and introduce ServerChannelFactory which takes an EventLoop and one EventLoopGroup to create new ServerChannel instances.
- Add ServerChannel.childEventLoopGroup()
- Ensure all operations on the accepted Channel is done in the EventLoop of the Channel in ServerBootstrap
- Change unit tests for new behaviour

Result:

A Channel always has an EventLoop assigned which will never change during its life-time. This ensures we are always be able to call any operation on the Channel once constructed (unit the EventLoop is shutdown). This also simplifies the logic in DefaultChannelPipeline a lot as we can always call handlerAdded / handlerRemoved directly without the need to wait for register() to happen.

Also note that its still possible to deregister a Channel and register it again. It's just not possible anymore to move from one EventLoop to another (which was not really safe anyway).

5ecb34ee72 Fix ClassCastException and native crash when using kqueue transport. (#8665)
Motivation:

How we did the mapping from native code to AbstractKQueueChannel was not safe and could lead to heap corruption. This then sometimes produced ClassCastExceptions or could also lead to crashes. This happened sometimes when running the testsuite.

Modifications:

Use a Map for the mapping (just as we do in the native epoll transport).

Result:

No more heap corruption / crashes.

Handling AUTO_READ should not be the responsibility of DefaultChannel… (#8650)
* Handling AUTO_READ should not be the responsibility of DefaultChannelPipeline but the Channel itself.

Motivation:

At the moment we do automatically call read() in the DefaultChannelPipeline when fireChannelReadComplete() / fireChannelActive() is called and the Channel is using auto read. This is nice in terms of sharing code but imho is not the responsibility of the ChannelPipeline implementation but the responsibility of the Channel implementation.

Modifications:

Move handing of auto read from DefaultChannelPipeline to Channel implementations.

Result:

More clear responsibiliy and not depending on implemention details of the ChannelPipeline.

3a96e7373b Added option to do busy-wait on epoll (#8267)
Motivation:

Add an option (through a SelectStrategy return code) to have the Netty event loop thread to do busy-wait on the epoll.

The reason for this change is to avoid the context switch cost that comes when the event loop thread is blocked on the epoll_wait() call.

On average, the context switch has a penalty of ~13usec.

This benefits both:

The latency when reading from a socket
Scheduling tasks to be executed on the event loop thread.
The tradeoff, when enabling this feature, is that the event loop thread will be using 100% cpu, even when inactive.

Modification:

Added SelectStrategy option to return BUSY_WAIT
Epoll loop will do a epoll_wait() with no timeout
Use pause instruction to hint to processor that we're in a busy loop
Result:

When enabled, minimizes impact of context switch in the critical path

6138541033 Avoid repeating the same field and hiding it (#8335)
Motivation

The EpollChannelConfig (same for KQueues) and its subclasses repeatetly declare their own channel field which leads to a 3x repetition for each config instance. Given the fields are protected or package-private it's exposing the code code to "field hiding" bugs.

Modifications

Use the the existing protected channel field from the DefaultChannelConfig class and simply cast it when needed.

* Allow to use native transports when sun.misc.Unsafe is not present on the system

Motivation:

We should be able to use the native transports (epoll / kqueue) even when sun.misc.Unsafe is not present on the system. This is especially important as Java11 will be released soon and does not allow access to it by default.

Modifications:

- Correctly disable usage of sun.misc.Unsafe when -PnoUnsafe is used while running the build
- Correctly increment metric when UnpooledDirectByteBuf is allocated. This was uncovered once -PnoUnsafe usage was fixed.
- Implement fallbacks in all our native transport code for when sun.misc.Unsafe is not present.

Ensure multiple shaded version of the same netty artifact can be loaded as long as the shaded prefix is different (#8207)
Motivation:

We should support to load multiple shaded versions of the same netty artifact as netty is often used in multiple dependencies.

This is related to https://github.com/netty/netty/issues/7272.

Modifications:

- Use -fvisibility=hidden when compiling and use JNIEXPORT for things we really want to have exported
- Ensure fields are declared as static so these are not exported
- Adjust testsuite-shading to use install_name_tool on MacOS to change the id of the lib. Otherwise the wrong may be used.

Result:

Be able to use multiple shaded versions of the same netty artifact.
