Only try to use reflection to access default nameservers when using Java8 and lower (#9157)
Motivation:

We should only try to use  reflection to access default nameservers when using Java8 and lower as otherwise we will produce an Illegal reflective access warning like:

WARNING: Illegal reflective access by io.netty.resolver.dns.DefaultDnsServerAddressStreamProvider

Modifications:

Add Java version check before try to use reflective access.

Result:

No more warning when Java9+ is used.

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.

Do not manually reset HttpObjectDecoder in HttpObjectAggregator.handleOversizedMessage(...) (#9017) (#9156)
Motivation:

We did manually call HttpObjectDecoder.reset() in HttpObjectAggregator.handleOversizedMessage(...) which is incorrect and will prevent correct parsing of the next message.

Modifications:

- Remove call to HttpObjectDecoder.reset()
- Add unit test

Result:

Verify that we can correctly parse the next request after we rejected a request.

Add support for TCP fallback when we receive a truncated DnsResponse (#9139)
Motivation:

Sometimes DNS responses can be very large which mean they will not fit in a UDP packet. When this is happening the DNS server will set the TC flag (truncated flag) to tell the resolver that the response was truncated. When a truncated response was received we should allow to retry via TCP and use the received response (if possible) as a replacement for the truncated one.

See https://tools.ietf.org/html/rfc7766.

Modifications:

- Add support for TCP fallback by allow to specify a socketChannelFactory / socketChannelType on the DnsNameResolverBuilder. If this is set to something different then null we will try to fallback to TCP.
- Add decoder / encoder for TCP
- Add unit tests

Result:

Support for TCP fallback as defined by https://tools.ietf.org/html/rfc7766 when using DnsNameResolver.

Add missing assume checks to skip tests if KeyManagerFactory can not be used (#9148)
Motivation:

Depending on what OpenSSL library version we use / system property that is set we need to skip tests that use KeyManagerFactory.

Modifications:

Add missing assume checks for tests that use KeyManagerFactory.

Result:

All tests pass even if KeyManagerFactory is not supported

3221bf6854 Remove the Handler only after it has initialized the channel (#9132)
Motivation:

Previously, any 'relative' pipeline operations, such as
ctx.pipeline().replace(), .addBefore(), addAfter(), etc
would fail as the handler was not present in the pipeline.

Modification:

Used the pattern from ChannelInitializer when invoking configurePipeline().

Result:

Fixes #9131

cb85e03d72 AsciiString.lastIndexOf(...) is implemented incorrectly (#9103)
Motivation

@xiaoheng1 reported incorrect behaviour of AsciiString.lastIndexOf in
#9099. Upon closer inspection it appears that it was never implemented
correctly and searches between the provided index and the end of the
string similar to indexOf(...), rather than between the provided index
and the beginning of the string as the javadoc states (and in line with
java.lang.String).

Modifications

Fix AsciiString.lastIndexOf implementation and corresponding unit tests
to behave the same as the equivalent String methods.

Result

Fixes #9099

60de092e36 Fix incorrect behavior of ReadOnlyByteBufferBuf.getBytes(int,ByteBuffer) (#9125)
* Fix incorrect behavior of ReadOnlyByteBufferBuf.getBytes(int,ByteBuffer)

Motivation

It currently will succeed when the destination is larger than the source
range, but the ByteBuf javadoc states this should be a failure, as is
the case with all the other implementations.

Modifications

- Fix logic to fail the bounds check in this case
- Remove explicit null check which isn't done in any equivalent method
- Add unit test

Result

More correct/consistent behaviour

DnsNameResolver.resolveAll(DnsQuestion) should not try to filter duplicates (#9141)
Motivation:

https://github.com/netty/netty/pull/9021 did apply some changes to filter out duplicates InetAddress when calling resolveAll(...) to mimic JDK behaviour. Unfortunally this also introduced a regression as we should not filter duplicates when the user explicit calls resolveAll(DnsQuestion).

Modifications:

- Only filter duplicates if resolveAll(String) is used
- Add unit test

Result:

Fixes regressions introduces by https://github.com/netty/netty/pull/9021

5a27f2f78b Allow to specify KeyStore type in SslContext (#9003)
Motivation:

As brought up in https://github.com/netty/netty/issues/8998, JKS can be substantially faster than pkcs12, JDK's new default. Without an option to set the KeyStore type you must change the configuration of the entire JVM which is impractical.

Modification:

- Allow to specify KeyStore type
- Add test case

Result:

Fixes https://github.com/netty/netty/issues/8998.

Allow to have DnsNameResolver.resolveAll(...) notify as soon as the preferred records were resolved (#9136)
Motivation:

075cf8c02e introduced a change to allow resolve(...) to notify as soon as the preferred record was resolved. This works great but we should also allow the user to configure that we want to do the same for resolveAll(...), which means we should be able to notify as soon as all records for a preferred record were resolved.

Modifications:

- Add a new DnsNameResolverBuilder method to allow configure this (use false as default to not change default behaviour)
- Add unit test

Result:

Be able to speed up resolving.

a74fead216 Fixed HttpHelloWorldServerHandler for handling HTTP 1.0/1.1 (#9124)
Motivation:

Modification:

Correctly set header

Result:

526f2da912 Add equality check to contentEquals instance methods. (#9130)
Motivation:

An instance is always equal to itself. It makes sense to skip processing for this case, which isn't uncommon since `AsciiString` is often memoized within an application when used as HTTP header names.

Modification:

`contentEquals` methods first check for instance equality before doing processing.

Result:

`contentEquals` will be faster when comparing an instance with itself.

I couldn't find any unit tests for these methods, only the static version. Let me know if I should add something to `AsciiStringCharacterTest`.

Came up here:

909a3d942e KQueueEventLoop won't unregister active channels reusing a file descriptor (#9114)
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.

Modifications:

Change the logic of KQueueEventLoop#remove(AbstractKQueueChannel) channels so it will check channels equality prior removal.

Result:

KQueueEventLoop won't remove anymore active channels reusing a file descriptor.

Always include classes from all native transports no matter on which platfrom netty-all is build (#9111)
Motivation:

While building netty-all we should always include all classes for native transports no matter if the native part can be build or not. This was it is easier to test locally with a installed snapshot of netty-all when the code that uses it does enable a specific native transport depending on if the native bits can be loaded or not.

Modifications:

Always include classes of native transports no matter on which platfrom we build. When a release is done we ensure we include the native bits by using the uber-staging profile.

Result:

Easier testing with netty-all snapshots.

Introduce DynamicAddressConnectHandler which can be used to dynamically change remoteAddress / localAddress when a connect is issued (#8982)
Motivation:

Bootstrap allows you to set a localAddress for outbound TCP connections, either via the Bootstrap.localAddress(localAddress) or Bootstrap.connect(remoteAddress, localAddress) methods. This works well if you want to bind to just one IP address on an interface. Sometimes you want to bind to a specific address based on the resolved remote address which should be possible.

Modifications:

Add DynamicAddressConnectHandler and tests

Result:

Fixes https://github.com/netty/netty/issues/8940.

c8ff76ba91 [openssl] fix refcount bug in OpenSslPrivateKeyMaterial ctor
Motivation:

Subclasses of `OpenSslKeyMaterial` implement `ReferenceCounted`. This means that a new object should have an initial refcount of 1. An `OpenSslPrivateKey.OpenSslPrivateKeyMaterial` object shares its refcount with the enclosing `OpenSslPrivateKey` object. This means the enclosing object's refcount must be incremented by 1 when an instance of `OpenSslPrivateKey.OpenSslPrivateKeyMaterial` is created. Otherwise, when the key material object is `release()`-ed, the refcount on the enclosing object will drop to 0 while it is still in use.

Modification:

- Increment the refcount in the constructor of `OpenSslPrivateKey.OpenSslPrivateKeyMaterial`
- Ensure we also always release the native certificates as well.

Result:

Refcount is now correct.

b9c4e17291 Invoke channelAcquired callback on first time channel acquire (#9093)
Motivation:

SimpleChannelPool provides ability to provide custom callbacks/handlers
on major events such as "channel acquired", "channel created" and
"channel released". In the current implementation, when a request to
acquire a channel is made for the first time, the internal channel pool
creates the channel lazily. This triggers the "channel created" callback
but does not invoke the "channel acquired" callback. This is contrary to
caller expectations who assumes that "channel acquired" will be invoked
at the end of every successful acquire call. It also leads to an
inconsistent API experience where the acquired callback is sometimes
invoked and sometimes it isn't depending on wheather the internal
mechanism is creating a new channel or re-using an existing one.

Modifications:

Invoke acquired callback consistenly even when creating a new channel
and modify the tests to support this behaviour

Result:

Consistent experience for the caller of acquire API. Every time they
call the API, the acquired callback will be invoked.

Http2MultiplexCodec.DefaultHttp2StreamChannel should handle ChannelConfig.isAutoClose() in a consistent way as AbstractChannel (#9108)
Motivation:

Http2MultiplexCodec.DefaultHttp2StreamChannel currently only act on ClosedChannelException exceptions when checking for isAutoClose(). We should widen the scope here to IOException to be more consistent with AbstractChannel.

Modifications:

Replace instanceof ClosedChannelException with instanceof IOException

Result:

More consistent handling of isAutoClose()

Adjust pom.xml to be able to build with graalvm (#9107)
Motivation:

When trying to use graalvm and build netty we currently fail because our build configuration is not compatible with it.

Modification:

- Skip plugins that are not supported when graal is used
- Correctly configure surefire plugin for graal so it not produces a NPE

Result:

We can build and test with graalvm.

f1495e1945 Add SVM metadata and minimal substitutions to build graalvm native image applications. (#8963)
Motivation:

GraalVM native images are a new way to deliver java applications. Netty is one of the most popular libraries however there are a few limitations that make it impossible to use with native images out of the box. Adding a few metadata (in specific modules will allow the compilation to success and produce working binaries)

Modification:

Added properties files in `META-INF` and substitutions classes (under `internal.svm`) will solve the compilation issues. The substitutions classes are not visible and do not have a public constructor so they are not visible to end users.

Result:

Fixes #8959 

This fix is very conservative as it applies the minimum config required to build:

* pure netty servers
* vert.x applications
* grpc applications

The build is having trouble due to checkstyle which does not seem to be able to find the copyright notice on property files.

Http2ConnectionHandler to allow decoupling close(..) from GOAWAY graceful close (#9094)
Motivation:
Http2ConnectionHandler#close(..) always runs the GOAWAY and graceful close
logic. This coupling means that a user would have to override
Http2ConnectionHandler#close(..) to modify the behavior, and the
Http2FrameCodec and Http2MultiplexCodec are not extendable so you cannot
override at this layer. Ideally we can totally decouple the close(..) of the
transport and the GOAWAY graceful closure process completely, but to preserve
backwards compatibility we can add an opt-out option to decouple where the
application is responsible for sending a GOAWAY with error code equal to
NO_ERROR as described in https://tools.ietf.org/html/rfc7540#section-6.8 in
order to initiate graceful close.

Modifications:
- Http2ConnectionHandler supports an additional boolean constructor argument to
opt out of close(..) going through the graceful close path.
- Http2FrameCodecBuilder and Http2MultiplexCodec expose
 gracefulShutdownTimeoutMillis but do not hook them up properly. Since these
are already exposed we should hook them up and make sure the timeout is applied
properly.
- Http2ConnectionHandler's goAway(..) method from Http2LifecycleManager should
initiate the graceful closure process after writing a GOAWAY frame if the error
code is NO_ERROR. This means that writing a Http2GoAwayFrame from
Http2FrameCodec will initiate graceful close.

Result:
Http2ConnectionHandler#close(..) can now be decoupled from the graceful close
process, and immediately close the underlying transport if desired.

00a9a25f29 Ensure channel handler close() is not skipped in !hasDisconnect case (#9098)
Motivation

The optimization in #8988 didn't correctly handle the specific case
where the channel hasDisconnect == false, and a
ChannelOutboundHandlerAdapter subclass overrides only the close(ctx,
promise) method without also overriding the disconnect(ctx, promise)
method.

Modifications

Adjust AbstractChannelHandler.disconnect(...) method to divert to
close(...) in !hasDisconnect case before computing target context for
the event.

Result

DefaultHeaders#valueIterator doesn't remove from the in bucket list (#9090)
Motivation:
DefaultHeaders entries maintains two linked lists. 1 for overall insertion order
and 1 for "in bucket" order. DefaultHeaders#valueIterator removal (introduced in 1d9090aab2) only reliably
removes the entry from the overall insertion order, but may not remove from the
bucket unless the element is the first entry.

Modifications:
- DefaultHeaders$ValueIterator should track 2 elements behind the next entry so
that the single linked "in bucket" list can be patched up when removing the
previous entry.

Result:
More correct DefaultHeaders#valueIterator removal.

Http2FrameCodec to simulate GOAWAY received when stream IDs are exhausted (#9095)
Motivation:
Http2FrameCodec currently fails the write promise associated with creating a
stream with a Http2NoMoreStreamIdsException. However this means the user code
will have to listen to all write futures in order to catch this scenario which
is the same as receiving a GOAWAY frame. We can also simulate receiving a GOAWAY
frame from our remote peer and that allows users to consolidate graceful close
logic in the GOAWAY processing.

Modifications:
- Http2FrameCodec should simulate a DefaultHttp2GoAwayFrame when trying to
create a stream but the stream IDs have been exhausted.

Result:
Applications can rely upon GOAWAY for graceful close processing instead of also
processing write futures.

ec62af01c7 DefaultHttp2ConnectionEncoder async SETTINGS ACK SimpleChannelPromiseAggregator promise usage
Motivaiton:
DefaultHttp2ConnectionEncoder uses SimpleChannelPromiseAggregator to combine two
operations into a single future status. However it directly uses the
SimpleChannelPromiseAggregator object instead of using the newPromise() method
in one case. This may result in premature completion of the aggregated future.

Modifications:
- DefaultHttp2ConnectionEncoder to use
  SimpleChannelPromiseAggregator#newPromise() instead of directly using the
SimpleChannelPromiseAggregator instance when writing the settings ACK frame

Result:
More correct status for the SETTING ACK frame writing when auto settings ACK is
disabled.

HTTP/2 to support asynchronous SETTINGS ACK (#9069)
Motivation:
The HTTP/2 codec will synchronously respond to a SETTINGS frame with a SETTINGS
ACK before the application sees the SETTINGS frame. The application may need to
adjust its state depending upon what is in the SETTINGS frame before applying
the remote settings and responding with an ACK (e.g. to adjust for max
concurrent streams). In order to accomplish this the HTTP/2 codec should allow
for the application to opt-in to sending the SETTINGS ACK.

Modifications:
- DefaultHttp2ConnectionDecoder should support a mode where SETTINGS frames can
  be queued instead of immediately applying and ACKing.
- DefaultHttp2ConnectionEncoder should attempt to poll from the queue (if it
  exists) to apply the earliest received but not yet ACKed SETTINGS frame.
- AbstractHttp2ConnectionHandlerBuilder (and sub classes) should support a new
  option to enable the application to opt-in to managing SETTINGS ACK.

Result:
HTTP/2 allows for asynchronous SETTINGS ACK managed by the application.

1d9090aab2 DefaultHeaders#valueIterator to support removal (#9063)
Motivation:
While iterating values it is often desirable to be able to remove individual
entries. The existing mechanism to do this involves removal of all entries and
conditional re-insertion which is heavy weight in order to remove a single
value.

Modifications:
- DefaultHeaders$ValueIterator supports removal

Result:
It is possible to remove entries while iterating the values in DefaultHeaders.

9ed41db1d7 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

DnsNameResolver.resolve(...) should notify future as soon as one preferred record was resolved (#9050)
Motivation:

At the moment resolve(...) does just delegate to resolveAll(...) and so will only notify the future once all records were resolved. This is wasteful as we are only interested in the first record anyway. We should notify the promise as soon as one record that matches the preferred record type is resolved.

Modifications:

- Introduce DnsResolveContext.isCompleteEarly(...) to be able to detect once we should early notify the promise.
- Make use of this early detecting if resolve(...) is called
- Remove FutureListener which could lead to IllegalReferenceCountException due double releases
- add unit test

Result:

Be able to notify about resolved host more quickly.
