465a190c3f [#4805] Respect isAutoRead() once re-register Channel
Motivation:

When a channel was registered before and is re-registered we need to respect ChannelConfig.isAutoRead() and so start reading one the registration task completes. This was done "by luck" before 15162202fb.

Modifications:

Explicit start reading once a Channel was re-registered if isAutoRead() is true.

Result:

Correctly receive data after re-registration completes.

08a7ca3747 Correctly pass ChannelPromise on to the next ChannelOutboundHandler when use CombinedChannelDuplexHandler.
Motivation:

Due a regression introduced by e969b6917c we missed to pass the original ChannelPromise to the next ChannelOutboundHandler and so
may never notify the origin ChannelPromise. This is related to #4805.

Modifications:

- Correctly pass the ChannelPromise
- Add unit test.

Result:

Correctly pass the ChannelPromise on deregister(...)

7ef6db3ffd [#4754] Correctly detect websocket upgrade
Motivation:

If the Connection header contains multiple values (which is valid) we fail to detect a websocket upgrade

Modification:

- Add new method which allows to check if a header field contains a specific value (and also respect multiple header values)
- Use this method to detect handshake

Result:

Correct detect handshake if Connection header contains multiple values (seperated by ',').

a0758e7e60 [#4794] Support window size flag by default if ZlibCodecFactory supports it.
Motivation:

If the ZlibCodecFactory can support using a custom window size we should support it by default in the websocket extensions as well.

Modifications:

Detect if a custom window size can be handled by the ZlibCodecFactory and if so enable it by default for PerMessageDeflate*ExtensionHandshaker.

Result:

Support window size flag by default in most installations.

7a562943ad [#4533] Ensure replacement of decoder is delayed after finishHandshake() is called
Motivation:

If the user calls handshake.finishHandshake() we need to ensure that the user has the chance to setup the pipeline before any WebSocketFrames are read. Because of this we need
to delay the removal of the HttpRequestDecoder.

Modifications:

- Remove the HttpRequestDecoder via the EventLoop and so delay it which gives the user a chance to setup the pipeline after finishHandshake() completes
- Add unit test for this.

Result:

Less surpising and correct behaviour even if the http response and websocket frame are received in one read operation.

ef0e053202 Preserve the host name of address when parsing /etc/hosts file
Motivation:

When an InetNameResolver resolves a name, it is expected to reserve the
requested host name in the resolved InetAddress.

DefaultHostsFileEntriesResolver does not preserve the host name. For
example, resolving 'localhost' will return an InetAddress whose address
is '127.0.0.1', but its getHostString() will not return 'localhost' but
just '127.0.0.1'.

Modifications:

Fix the construction of parsed InetAddresses in HostsFileParser

Result:

Host name is preserved in the resolved InetAddress

075a54af3e Native EPOLL Library Allows Shading
Motivation:
If Netty's class files are renamed and the type references are updated (shaded) the native libraries will not function. The native epoll module uses implicit JNI bindings which requires the fully qualified java type names to match the method signatures of the native methods. This means EPOLL cannot be used with a shaded Netty.

Modifications:
- Make the JNI method registration dynamic
- support a system property io.netty.packagePrefix which must be prepended to the name of the native library (to ensure the correct library is loaded) and all class names (to allow classes to be correctly referenced)
- remove system property io.netty.native.epoll.nettyPackagePrefix which was recently added and the code to support it was incomplete

Result:
transport-native-epoll can be used when Netty has been shaded.

eb1d9da76c Enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext
Motivation:

We need to enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext as the memory address of the buffer that is passed to OpenSslEngine.wrap(...) may change during calls and retries. This is the case as
if the buffer is a heap-buffer we will need to copy it to a direct buffer to hand it over to the JNI layer. When not enable this mode we may see errors like: 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry'.
Related to https://github.com/netty/netty-tcnative/issues/100.

Modifications:

Explitict set mode to SSL.SSL_MODE_RELEASE_BUFFERS | SSL.SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER . (SSL.SSL_MODE_RELEASE_BUFFERS was used before implicitly).

Result:

No more 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry' possible when writing heap buffers.

Motivation:

fix the issue netty#2944

Modifications:

use - instead of =>, use ! instead of :> due to the connection is bidirectional. What's more, toString() method don't know the direction or there is no need to know the direction when only log channel information.
add L: before local address and R: before remote address.

Result:

after the fix, log won't confuse the user

6312c2f00b CompositeByteBuf.addComponent always assume reference count ownership
Motivation:
The current interface for CompositeByteBuf.addComponent is not clear under what conditions ownership is transferred when addComponent is called. There should be a well defined behavior so that users can ensure that no leaks occur.

Modifications:
- CompositeByteBuf.addComponent should always assume reference count ownership

Result:
Users that call CompositeByteBuf.addComponent do not have to independently check if the buffer's ownership has been transferred and if not independently release the buffer.

7a7160f176 HTTP/2 Buffer Leak if UTF8 Conversion Fails
Motivation:
Http2CodecUtil uses ByteBufUtil.writeUtf8 but does not account for it
throwing an exception. If an exception is thrown because the format is
not valid UTF16 encoded UTF8 then the buffer will leak.

Modifications:
- Make sure the buffer is released if an exception is thrown
- Ensure call sites of the Http2CodecUtil.toByteBuf can tolerate and
  exception being thrown

Result:
No leak if exception data can not be converted to UTF8.

a75dcb2756 Made it easier to use custom ChannelId instances with Channel implementations that rely on the AbstractChannel(Channel parent) constructor.
Motivation:

The AbstractChannel(Channel parent) constructor was previously hard-coded to always
call DefaultChannelId.newInstance(), and this made it difficult to use a custom
ChannelId implementation with some commonly used Channel implementations.

Modifications:

Introduced newId() method in AbstractChannel, which by default returns
DefaultChannelId.newInstance() but can be overridden by subclasses. Added
ensureDefaultChannelId() test to AbstractChannelTest, to ensure the prior
behavior of calling DefaultChannelId.newInstance() still holds with the
AbstractChannel(Channel parent) constructor.

Result:

AbstractChannel now has the protected newId() method, but there is no functional
difference.

d97f17060f Support non chunked HTTP request bodies larger than Integer.MAX_VALUE.
Motivation:

Request bodies can easily be larger than Integer.MAX_VALUE in practice.
There's no reason, or intention, for Netty to impose this artificial constraint.

Worse, it currently does not fail if the body is larger than this value;
it just silently only reads the first Integer.MAX_VALUE bytes and discards the rest.

This restriction doesn't effect chunked transfers, with no Content-Length header.

Modifications:

Force the use of `long HttpUtil.getContentLength(HttpMessage, long)` instead of
`long HttpUtil.getContentLength(HttpMessage, long)`.

Result:

Netty will support HTTP request bodies of up to Long.MAX_VALUE length.

f990f9983d HTTP/2 Don't Flow Control Iniital Headers
Motivation:
Currently the initial headers for every stream is queued in the flow controller. Since the initial header frame may create streams the peer must receive these frames in the order in which they were created, or else this will be a protocol error and the connection will be closed. Tolerating the initial headers being queued would increase the complexity of the WeightedFairQueueByteDistributor and there is benefit of doing so is not clear.

Modifications:
- The initial headers will no longer be queued in the flow controllers

Result:

5fb18e3415 InboundHttp2ToHttpAdapter leak and logic improvements
Motivation:
In HttpConversionUtil's toHttpRequest and toHttpResponse methods can
allocate FullHttpMessage objects, and if an exeception is thrown during
the header conversion then this object will not be released. If a
FullHttpMessage is not fired up the pipeline, and the stream is closed
then we remove from the map, but do not release the object. This leads
to a ByteBuf leak. Some of the logic related to stream lifetime management
and FullHttpMessage also predates the RFC being finalized and is not correct.

Modifications:
- Fix leaks in HttpConversionUtil
- Ensure the objects are released when they are removed from the map.
- Correct logic and unit tests where they are found to be incorrect.

Result:

4d6ab1d30d Fix missing trailing data on HTTP client upgrade
Motivation:

When HttpClientUpgradeHandler upgrades from HTTP/1 to another protocol,
it performs a two-step opertion:

1. Remove the SourceCodec (HttpClientCodec)
2. Add the UpgradeCodec

When HttpClientCodec is removed from the pipeline, the decoder being
removed triggers channelRead() event with the data left in its
cumulation buffer. However, this is not received by the UpgradeCodec
becuase it's not added yet. e.g. HTTP/2 SETTINGS frame sent by the
server can be missed out.

To fix the problem, we need to reverse the steps:

1. Add the UpgradeCodec
2. Remove the SourceCodec

However, this does not work as expected either, because UpgradeCodec can
send a greeting message such as HTTP/2 Preface. Such a greeting message
will be handled by the SourceCodec and will trigger an 'unsupported
message type' exception.

To fix the problem really, we need to make the upgrade process 3-step:

1. Remove/disable the encoder of SourceCodec
2. Add the UpgradeCodec
3. Remove the SourceCodec

Modifications:

- Add SourceCodec.prepareUpgradeFrom() so that SourceCodec can remove or
  disable its encoder
- Implement HttpClientCodec.prepareUpgradeFrom() properly
- Miscellaneous:
  - Log the related channel as well When logging the failure to send a
    GOAWAY

Result:

Cleartext HTTP/1-to-HTTP/2 upgrade works again.

11bcb8790c Http2Connection stream id generation to support queueing
Motivation:
StreamBufferingEncoder provides queueing so that MAX_CONCURRENT_STREAMS is not violated. However the stream id generation provided by Http2Connection.nextStreamId() only returns the next stream id that is expected on the connection and does not account for queueing. The codec should provide a way to generate the next stream id for a given endpoint that functions with or without queueing.

Modifications:
- Change Http2Connection.nextStreamId to Http2Connection.incrementAndGetNextStreamId

Result:
Http2Connection can generate the next stream id in queued and non-queued scenarios.

8ba4b63cb6 OioServerChannel Default Max Messages Per Read Too High
Motivation:
A few implementations of OioServerChannel have a default max messages per read set to 16. We should set the default to 1 to prevent blocking on a read before setting a socket that has just been accepted.

Modifications:
- OioSctpServerChannel and OioServerSocketChannel metadata changed to use the default (1) max messages per read

Result:
Oio based servers will complete accepting a socket before potentially blocking waiting to accept other sockets.

4606890513 Retain AbstractBinaryMemcacheDecoder.currentMessage when sending it out and release it when it's not used.
Motivation:

AbstractBinaryMemcacheDecoder.currentMessage is not retained after sending it out. Hence, if a message contains `extras`, `io.netty.util.IllegalReferenceCountException` will be thrown in `channelInactive`.

Modifications:

Retain AbstractBinaryMemcacheDecoder.currentMessage After putting it to `out` and release it when it's not used.

Result:

No IllegalReferenceCountException or leak.

e1d34ef05d SslHandler should call beginHanshake once for the initial handshake
Motivation:
Not all SSLEngine implementations permit beginHandshake being called while a handshake is in progress during the initial handshake. We should ensure we only go through the initial handshake code once to prevent unexpected exceptions from being thrown.

af39cb6b12 Ensure ChannelHandler.handlerAdded(...) is always called as first method of the handler
Motivation:

If a user adds a ChannelHandler from outside the EventLoop it is possible to get into the situation that handlerAdded(...) is scheduled on the EventLoop and so called after another methods of the ChannelHandler as the EventLoop may already be executing on this point in time.

Modification:

- Ensure we always check if the handlerAdded(...) method was called already and if not add the currently needed call to the EventLoop so it will be picked up after handlerAdded(...) was called. This works as if the handler is added to the ChannelPipeline from outside the EventLoop the actual handlerAdded(...) operation is scheduled on the EventLoop.
- Some cleanup in the DefaultChannelPipeline

Result:

Correctly order of method executions of ChannelHandler.

ca305d86fb PlatformDependent String char[] optimization
Motivation:
PlatformDependent0 has an optimization which grabs the char[] from a String. Since this code was introduced http://openjdk.java.net/jeps/254 has been gaining momentum in JDK 9. This JEP changes the internal storage from char[] to byte[], and thus the existing char[] only based optimizations will not work.

Modifications:
- The ASCII encoding char[] String optimizations should also work for byte[].

Result:
ASCII encoding char[] String optimizations don't break if the underlying storage in String is byte[].

af4f70ba28 More efficiently allocate header buffer.
Motivation
----------
Currently, only the fixed 24 bytes are allocated for the header and
then all the params as well as the optional extras and key are written
into the header section.

It is very likely that the buffer needs to expand at least two times
if either the extras and/or the key take up more space.

Modifications
-------------
Since at the point of allocation we know the key and extras length,
the buffer can be preallocated with the exact size, avoiding unnecessary
resizing and even allocating too much (since it uses power of two
internally).

Result
------
Less buffer resizing needed when encoding a memcache operation.

6dbb610f5b Add ChannelHandlerContext.invoker()
Motivation:

Being able to access the invoker() is useful when adding additional
handlers that should be running in the same thread. Since an application
may be using a threading model unsupported by the default invoker, they
can specify their own. Because of that, in a handler that auto-adds
other handlers:

// This is a good pattern
ctx.pipeline().addBefore(ctx.invoker(), ctx.name(), null, newHandler);
// This will generally work, but prevents using custom invoker.
ctx.pipeline().addBefore(ctx.executor(), ctx.name(), null, newHandler);

That's why I believe in commit 110745b0, for the now-defunct 5.0 branch,
when ChannelHandlerAppender was added the invoker() method was also
necessary.

There is a side-benefit to exposing the invoker: in certain advanced
use-cases using the invoker for a particular handler is useful. Using
the invoker you are able to invoke a _particular_ handler, from possibly
a different thread yet still using standard exception processing.

ChannelHandlerContext does part of that, but is unwieldy when trying to
invoke a particular handler because it invokes the prev or next handler,
not the one the context is for. A workaround is to use the next or prev
context (respectively), but this breaks when the pipeline changes.

This came up during writing the Http2MultiplexCodec which uses a
separate child channel for each http/2 stream and wants to send messages
from the child channel directly to the Http2MultiplexCodec handler that
created it.

Modifications:

Add the invoker() method to ChannelHandlerContext. It was already being
implemented by AbstractChannelHandlerContext. The two other
implementations of ChannelHandlerContext needed minor tweaks.

Result:

Access to the invoker used for a particular handler, for either reusing
for other handlers or for advanced use-cases. Fixes #4738

PlatformDependent allows some exceptions to escape during static initialization. If an exception escapes it will be translated into a java.lang.ExceptionInInitializerError and render the application unable to run.

Modifications:
- Make sure to catch Throwable during static initialization.

Result:
PlatformDependent static initialization doesn't result in java.lang.ExceptionInInitializerError.
