908464f161 make the http2 codec void promise ready.
Motivation:

Void promises need special treatment, as they don't behave like normal promises. One
cannot add a listener to a void promise for example.

Modifications:

Inspected the code for addListener() calls, and added extra logic for void promises
where necessary. Essentially, when writing a frame with a void promise, any errors
are reported via the channel pipeline's exceptionCaught event.

Result:

The HTTP/2 codec has better support for void promises.

e3462a79c7 MessageAggregator Potential Leak
Motivation:
MessageAggregator has a potential to leak if a new message is received before the existing message has completed, and if a HttpContent is received but maxContentLength has been exceeded, or the content length is too long.

Modifications:

- Make the HttpObjectAggregator more robust to leaks
- Reduce dependance on handlingOversizedMessage but instead rely on the more general check of a null currentMessage

Result:
More robust MessageAggregator with less chance of leaks

eb7f751ba5 Log less confusing message when try to load native library
Motivation:

At the moment we log very confusing messages when trying to load a native library which kind of suggest that the whole loading process failed even if just one mechanism failed and the library could be loaded at the end.

Modifications:

Make the mesage less confusing and also log a successful load of the native library.

Result:

Less confusing logs.

4a18a143d2 Only set lastReadTime if an read actually happened before in IdleStateHandler.
Motivation:

IdleStateHandler and ReadTimeoutHandler could mistakely not fire an event even if no channelRead(...) call happened.

Modifications:

Only set lastReadTime if a read happened before.

Result:

More correct IdleStateHandler / ReadTimeoutHandler.

f375772ff0 Remove OSGi import of JCTools since it is shaded.
Motivation:

Since netty shaded JCTools the OSGi manifest no longer is correct. It claims to
have an optional import "org.jctools.queues;resolution:=optional,org.jctools.qu
eues.atomic;resolution:=optional,org.jctools.util;resolution:=optional"
However since it is shaded, this is no longer true.
This was noticed when making JCTools a real bundle and netty resolved it as
optional import.

Modifications:

Modify the generated manifest by no longer analyzing org.jctools for imports.
A manual setting of sun.misc as optional was required.

Result:

Netty OSGi bundle will no longer interfere with a JCTools bundle.

4beb075dd3 Ensure we only call debugData.release() if we called debugData.retain()
Motivation:

We need to ensure we only call debugData.release() if we called debugData.retain(), otherwise we my see an IllegalReferenceCountException.

Modifications:

Only call release() if we called retain().

Result:

No more IllegalReferenceCountException possible.

51629245d0 Call debugData.retain() before we forward the frame to the pipeline
Motivation:

We need to call debugData.retain() before we forward the frame to the pipeline as ByteToMessageDecoder will call release() on the buffer.

Modifications:

Correctly retain debugData and fix the unit test to test for it.

Result:

No more IllegalReferenceCountException when using the Http2FrameCodec.

245fb52c90 Provide extra info together with handshake complete event.
Motivation:

As described in #5734

Before this change, if the server had to do some sort of setup after a
handshake was completed based on handshake's information, the only way
available was to wait (in a separate thread) for the handshaker to be
added as an attribute to the channel. Too much hassle.

Modifications:

Handshake completed event need to be stateful now, so I've added a tiny
class holding just the HTTP upgrade request and the selected subprotocol
which is fired as an event after the handshake has finished.
I've also deprecated the old enum used as stateless event and I left the
code that fires it for backward compatibility. It should be removed in
the next mayor release.

Result:

It should be much simpler now to do initialization stuff based on
subprotocol or request headers on handshake completion. No asynchronous
waiting needed anymore.

d2389a9339 [#5762] HTTP/2: SETTINGS_HEADER_TABLE_SIZE should be an unsigned int
Motivation:

he HTTP/2 spec demands that the max value for SETTINGS_HEADER_TABLE_SIZE should be an unsigned 32-bit integer.

Modifications:

Change the limit to unsigned 32-bit integer and add tests.

Result:

67d3a78123 Reduce bytecode size of PlatformDependent0.equals.
Motivation:

PP0.equals has a bytecode size of 476. This is above the default inlining threshold of OpenJDK.

Modifications:

Slightly change the method to reduce the bytecode size by > 50% to 212 bytes.

Result:

The bytecode size is dramatically reduced, making the method a candidate for inlining.
The relevant code in our application (gRPC) that relies heavily on equals comparisons,
runs some ~10% faster. The Netty JMH benchmark shows no performance regression.

Current 4.1:

PlatformDependentBenchmark.unsafeBytesEqual      10  avgt   20     7.836 ±   0.113  ns/op
PlatformDependentBenchmark.unsafeBytesEqual      50  avgt   20    16.889 ±   4.284  ns/op
PlatformDependentBenchmark.unsafeBytesEqual     100  avgt   20    15.601 ±   0.296  ns/op
PlatformDependentBenchmark.unsafeBytesEqual    1000  avgt   20    95.885 ±   1.992  ns/op
PlatformDependentBenchmark.unsafeBytesEqual   10000  avgt   20   824.429 ±  12.792  ns/op
PlatformDependentBenchmark.unsafeBytesEqual  100000  avgt   20  8907.035 ± 177.844  ns/op

With this change:

PlatformDependentBenchmark.unsafeBytesEqual      10  avgt   20      5.616 ±   0.102  ns/op
PlatformDependentBenchmark.unsafeBytesEqual      50  avgt   20     17.896 ±   0.373  ns/op
PlatformDependentBenchmark.unsafeBytesEqual     100  avgt   20     14.952 ±   0.210  ns/op
PlatformDependentBenchmark.unsafeBytesEqual    1000  avgt   20     94.799 ±   1.604  ns/op
PlatformDependentBenchmark.unsafeBytesEqual   10000  avgt   20    834.996 ±  17.484  ns/op
PlatformDependentBenchmark.unsafeBytesEqual  100000  avgt   20   8757.421 ± 187.555  ns/op

6bbf32134a Log more details if notification of promise fails in PromiseNotifier and AbstractChannelHandlerContext
Motivation:

To make it easier to debug why notification of a promise failed we should log extra info and make it consistent.

Modifications:

- Create a new PromiseNotificationUtil that has static methods that can be used to try notify a promise and log.
- Reuse this in AbstractChannelHandlerContext, ChannelOutboundBuffer and PromiseNotifier

Result:

Easier to debug why a promise could not be notified.

8566fd1019 Add startTls parameter to SslContextBuilder
Motivation:

There is an incoherence in terms of API when one wants to use
startTls: without startTls one can use the SslContextBuilder's
method newHandler, but with startTls, the developper is forced
to call directly the SslHandler constructor.

Modifications:

Introduce startTls as a SslContextBuilder parameter as well as a
member in SslContext (and thus Jdk and OpenSsl implementations!).
Always use this information to call the SslHandler constructor.
Use false by default, in particular in deprecated constructors of
the SSL implementations.
The client Context use false by default

Results:

Fixes #5170 and more generally homogenise the API so that
everything can be done via SslContextBuilder.

b604a22395 Expose the ChannelHandlerContext from SniHandler's select() step to the user.
Motivation

I'm looking to harden our SSL impl. a little bit and add some guards agaist certain types of abuse. One can think of invalid hostname strings in the SNI extenstion or invalid SNI handshakes altogether. This will require measuring, velocity tracking and other things.

Modifications

Adding a protected `lookup(ctx, hostname)` method that is called from SniHandler's `select(...)` method which users can override and implement custom behaviour. The default implementation will simply call the AsyncMapper.

Result

It's possible to get a hold onto the ChannelHandlerContext. Users can override that method and do something with it right there or they can delegate it to something else. SniHandler is happy as long as a `Future<SslContext>` is being returned.

e3aca1f3d6 CorsHandler to respect http connection (keep-alive) header.
Motivation:

The CorsHandler currently closes the channel when it responds to a preflight (OPTIONS)
request or in the event of a short circuit due to failed validation.

Especially in an environment where there's a proxy in front of the service this causes
unnecessary connection churn.

Modifications:

CorsHandler now uses HttpUtil to determine if the connection should be closed
after responding and to set the Connection header on the response.

Result:

Channel will stay open when the CorsHandler responds unless the client specifies otherwise
or the protocol version is HTTP/1.0

dfa3bbbf00 Add support for Client Subnet in DNS Queries (RFC7871)
Motivation:

RFC7871 defines an extension which allows to request responses for a given subset.

Modifications:

- Add DnsOptPseudoRrRecord which can act as base class for extensions based on EDNS(0) as defined in RFC6891
- Add DnsOptEcsRecord to support the Client Subnet in DNS Queries extension
- Add tests

Result:

Client Subnet in DNS Queries extension is now supported.

- Add interopt unit tests to ensure no duplicates are send.

Result:

Modifications:

Mark method protected.

Result:

4af6855695 Remove @Deprecated for primitive WriteWaterMark getters and setters
Motivation:

For use cases that demand frequent updates of the write watermarks, an
API that requires immutable WriteWaterMark objects is not ideal, as it
implies a lot of object allocation.

For example, the HTTP/2 child channel API uses write watermarks for outbound
flow control and updates the write watermarks on every DATA frame write.

Modifications:

Remote @Deprecated tag from primitive getters and setters, however the corresponding
channel options remain deprecated.

Result:

Primitive getters and setters for write watermarks are no longer marked @Deprecated.

30fe2e868f Call finishConnect() before try to call read(...) / write(...) when using NIO
Motivation:

The JDK implementation of SocketChannel has an internal state that is tracked for its operations. Because of this we need to ensure we call finishConnect() before try to call read(...) / write(...) as otherwise it may produce a NotYetConnectedException.

Modifications:

First process OP_CONNECT flag.

Result:

No more possibility of NotYetConnectedException because OP_CONNECT is handled not early enough when processing interestedOps for a Channel.

00c0664ef8 Avoid inaccessible object exception replacing set
Motivation:

When attempting to set the selectedKeys fields on the selector
implementation, JDK 9 can throw an inaccessible object exception.

Modications:

Catch and log this exception as an possible course of action if the
sun.nio.ch package is not exported from java.base.

Result:

The selector replacement will fail gracefully as an expected course of
action if the sun.nio.ch package is not exported from java.base.

4477eb2f48 Fix native library loading in Windows
Motivation:

Windows refuses to load a .DLL file when it's opened by other process.
Recent modification in NativeLibraryLoader causes NativeLibraryLoader to
attempt to load a .DLL before closing its OutputStream. As a result,
loading a .DLL file in Windows always fails.

Modifications:

Close the OutputStream explicitly before loading a shared library.

Result:

Native library loading in Windows works again.

f6c16f4897 Attempt at improving docs in HttpObjectAggregator
Motivation:

Documentation was added in #2401 to aid developers in understanding
how HttpObjectAggregator works and that it needs an encoder before it.

In #2471 it was pointed out that the documentation added can actually
add to the confusion and that it might have a typo.

This is an attempt at clearing up that confusion.  Feedback is welcome.

Modifications:

- Adjust class level javadoc for HttpObjectAggregator
  * Remove reference to HttpRequestEncoder
  * Point out when HttpResponseEncoder is needed
  * Point out that either HttpRequestDecoder or HttpResponseDecoder is needed
  * Make clear everything must be added before HttpObjectAggregator
  * Mention HttpServerCodec

Result:

Avoid confusion about dependencies for HttpObjectAggregator on the pipeline.

f97866dbc6 Expose SniHandler's replaceHandler() so that users can implement custom behavior.
Motivation

The SniHandler is currently hiding its replaceHandler() method and everything that comes with it. The user has no easy way of getting a hold onto the SslContext for the purpose of reference counting for example. The SniHandler does have getter methods for the SslContext and hostname but they're not very practical or useful. For one the SniHandler will remove itself from the pipeline and we'd have to track a reference of it externally and as we saw in #5745 it'll possibly leave its internal "selection" object with the "EMPTY_SELECTION" value (i.e. we've just lost track of the SslContext).

Modifications

Expose replaceHandler() and allow the user to override it and get a hold onto the hostname, SslContext and SslHandler that will replace the SniHandler.

Result

It's possible to get a hold onto the SslContext, the hostname and the SslHandler that is about to replace the SniHandler. Users can add additional behavior.

d3cb95ef00 Make NIO and EPOLL transport connect errors more consistent with the JDK
Motivation:

The NIO transport used an IllegalStateException if a user tried to issue another connect(...) while the connect was still in process. For this case the JDK specified a ConnectPendingException which we should use. The same issues exists in the EPOLL transport. Beside this the EPOLL transport also does not throw the right exceptions for ENETUNREACH and EISCONN errno codes.

Modifications:

- Replace IllegalStateException with ConnectPendingException in NIO and EPOLL transport
- throw correct exceptions for ENETUNREACH and EISCONN in EPOLL transport
- Add test case

Result:

More correct error handling for connect attempts when using NIO and EPOLL transport

3a6157e2aa Unit Test for SslHandler's handlerRemoved()
Motivation

SslHandler's handlerRemoved() is supposed to release the SSLEngine (which it does) but there is no Test for it to make sure it really happens and doesn't unexpectedly change in the future.

Modifications

Add a Unit Test that makes sure that SslHandler releases the SSLEngine when the Channel gets closed.

Result

Assurance that SslHandler will not leak (ReferenceCounted) SSLEngines.

Motivation:

Result of ByteBufUtil.compare(ByteBuf a, ByteBuf b) is dependent on ByteOrder of supplied ByteBufs which should not be the case (as stated in the javadocs).

Modifications:

Ensure we get a consistent behavior when calling ByteBufUtil.compare(ByteBuf a, ByteBuf b) and not depend on ByteOrder.

Result:

ByteBufUtil.compare(ByteBuf a, ByteBuf b) and so AbstractByteBuf.compare(...) works correctly as stated in the javadocs.

5b46cf25c1 Fulfill the write promise of empty HTTP/2 DATA frames sooner
Motivation:

DefaultHttp2ConnectionEncoder.FlowControlledData.write() does not
complete the write promise of empty HTTP/2 DATA frames until either a
non-DATA frame, a non-empty DATA frame or a DATA frame with endOfStream
set. This makes the write promise of the empty DATA frame is notified
much later than it could be.

Modifications:

- Notify the write promise of the empty DATA frames immediately is the
  queue contains empty DATA frames only

Result:

The write promise of an empty DATA frame is notified sooner.

acb40a87c3 SniHandler reference count leak if pipeline replace fails
Motivation:
The SniHandler attempts to generate a new SslHandler from the selected SslContext in a and insert that SslHandler into the pipeline. However if the underlying channel has been closed or the pipeline has been modified the pipeline.replace(..) operation may fail. Creating the SslHandler may also create a SSLEngine which is of type ReferenceCounted. The SslHandler states that if it is not inserted into a pipeline that it will not take reference count ownership of the SSLEngine. Under these conditions we will leak the SSLEngine if it is reference counted.

Modifications:
- If the pipeline.replace(..) operation fails we should release the SSLEngine object.

Result:
Fixes https://github.com/netty/netty/issues/5678

4accd300e5 Fix write watermarks comparison to use less than and greater than.
Motivation:

The API documentation in ChannelConfig states that a a channel is writable,
if the number of pending bytes is below the low watermark and a
channel is not writable, if the number of pending bytes exceeds the high
watermark.

Therefore, we should use < operators instead of <= as well as > instead of >=.

Using <= and >= is also problematic, if the low watermark is equal to the high watermark,
as then a channel could be both writable and unwritable with the same number of pending
bytes (depending on whether remove() or addMessage() is called first).

The use of <= and >= was introduced in PR https://github.com/netty/netty/pull/3036, but
I don't understand why, as there doesn't seem to have been any discussion around that.

Modifications:

Use < and > operators instead of <= and >=.

Result:

High and low watermarks are treated as stated in the API docs.

43626ac6ea Use NIO methods when using Java7+ in the NIO transport
Motivation:

We use often javachannel().socket().* in NIO as these methods exists in java6. The problem is that these will throw often very general Exceptions (Like SocketException) while it is more expected to throw the Exceptions listed in the nio interfaces. When possible we should use the new methods available in java7+ which throw the correct exceptions.

Modifications:

Check for java version and depending on it using the socket or the javachannel.

Result:

Throw expected Exceptions.
