58c63b7888 Add support for directly decoding/encoding DNS PTR Records
Motivation:

The current implementation will provide a DnsRawRecord, which, while
containing the host name it resolves to, would require the user to
decode the name using the decode method currently private to
DefaultDnsRecordDecoder, which in fact means copying it.

Modifications:

Introduce DnsPtrRecord, which is a specialization of DnsRecord which
provides a decoded host name.

Result:

PTR Records are much easier to work with, as the name is decoded already.

45d291bb15 Add asserts so users will see errors when try to use methods from outside the EventLoop.
Motivation:

We should guard users from using Unsafe methods from outside the EventLoop if not designed to do so.

Modifications:

Add asserts

Result:

Easier for users to detect miss-use.

d0f7f98d22 e2f5012 unit test cleanup
Motivation:
e2f5012 added unit tests which did not verify the buffer was released as it was intended to.

Modification:
- Unit tests must verify release is called

Result:
Unit tests enforce that ByteBufs are released.

e2f5012f3b DefaultChannelHandlerInvoker write leak
Motivation:
DefaultChannelHandlerInvoker.invokeWrite calls a utility method validatePromise which may throw if the arguments are not valid. If this method throws then the message will not be released.

Modifications:
- If an exception is thrown the message should be released

Result:
No more leak in DefaultChannelHandlerInvoker.invokeWrite

ef8dcae9af Fix potential infinite loop when resolving CNAME records
Related: #4771

Motivation:

A malicious or misconfigured DNS server can send the CNAME records that
resolve into each other, causing an unexpected infinite loop in
DnsNameResolverContext.onResponseCNAME().

Modifications:

- Remove the dereferenced CNAME from the alias map so that infinite loop
  is impossible.
- Fix inspection warnings and typos in DnsNameResolverTest

Result:

Fixes #4771

d8658989e1 Use smaller connect timeout to speed up tests.
Motivation:

For on tests we expected a ConnectTimeoutException but used the default timeout of 10 seconds. This slows down testing.

Modifications:

Use connect timeout of 1 second in unit test.

Result:

Faster execution of unit test.

900353af52 HTTP/2 Reduce Log Level
Motivation:
83c4aa6ad8 changed the log level to warn, but should have changed to debug.

Modifications:
- Change the log level to debug in Http2ConnectionHandler if the GO_AWAY fails to send. The write failure could be the result of the channel already being closed.

Result:
Fixes https://github.com/netty/netty/issues/4930.

68bbd4e966 Handle only those http requests that equal to adjusted websocket path
Motivation:

It will be easier to support websockets in server application by using WebSocketServerProtocolHandshakeHandler class and not reinvent its functionality. But currently it handles all http requests as if they were websocket handshake requests.

Modifications:

Check if http request path is equals to adjusted websocket path.
Fixed example of websocket server implementation.

Result:

WebSocketServerProtocolHandshakeHandler handles only websocket handshake requests.

4b5b230802 HTTP/2 DefaultHttp2HeadersDecoder weighted average error
Motiviation:
cfcee5798d introduced code to resize the headers based upon a weighted average. The weight used for new entries was initialized using integer arithmetic when it should have been floating point arithmetic and so new values contribute 0 weight.

Modifications:
- Cast to float when initializing

Result:
Weighted average does not give 0 weight to new headers in DefaultHttp2HeadersDecoder.

9aac6dac2e [#4386] ByteToMessage.decodeLast(...) should not call decode(...) if buffer is empty.
Motivation:

If the input buffer is empty we should not have decodeLast(...) call decode(...) as the user may not expect this.

Modifications:

- Not call decode(...) in decodeLast(...) if the input buffer is empty.
- Add testcases.

Result:

decodeLast(...) will not call decode(...) if input buffer is empty.

c4fbc0642d HTTP/2 stream removed from map before onStreamClosed called
Motivation:
The interface contract of Http2Connection.Listener.onStreamClosed says that the stream will be removed from the active stream map, and not necessarily the stream map. If the channel becomes inactive we may remove from the stream map before calling onStreamClosed.

Modifications:
- Don't remove from the stream map during iteration until after onStreamClosed is called

Result:
Expectations of onStreamClosed interface are not violated

94f27be59b ByteBufUtil writeUtf8 and writeAscii helper methods
Motivation:
Utility methods in ByteBufUtil to writeUtf8 and writeAscii expect a buffer to already be allocated. If the user does not have a buffer allocated they have to know details of the encoding in order to know the size of the buffer to allocate.

Modifications:
- Add writeUtf8 and writeAscii which take a ByteBufAllocator and allocate a ByteBuf of the correct size for the user

Result:
ByteBufUtil methods which are easier to use if the user doesn't already have a ByteBuf.

a2e113b987 Use ByteProcessor.FIND_LF to find end of line
Motivation:

Each call of ByteBuf.getByte(int) method does boundary checking. This can be eliminated by using ByteBuf.forEachByte(ByteProcessor) method and ByteProcessor.FIND_LF processor.

Modifications:

Find end of line with ByteProcessor.FIND_LF

Result:

A little better performance of LineBasedFrameDecoder.

b426566617 DnsNameResolver: makes possible to define additional records in DNS query
Motivation:

Current DnsNameResolver api don't allow to define additional records in DNS query.
It can be useful in many cases. For example when we want to query dns server with
real client address (EDNS-CLIENT-SUBNET extension:
http://tools.ietf.org/html/draft-vandergaast-edns-client-subnet-02 )

Modifications:

This change add new query methods with list of additional DnsRecord-s for query.

Result:

It is possible to create dns query with EDNS-CLIENT-SUBNET extension for example.

050ac709ba PromiseNotifier does not propagate cancel events
Motivation:
If the Future that the PromiseNotifier is listening to is cancelled, it does not propagate the cancel to all the promises it is expected to notify.

Modifications:
- If the future is cancelled then all the promises should be cancelled
- Add a UnaryPromiseNotifier if a collection of promises is not necessary

Result:
PromiseNotifier propagates cancel events to all promises

6e9d2bf13c Correctly set the alert type depending of the CertificateException
Motivation:

Depending on the actual CertificateException we should set the correct alert type so it will be sent back to the remote peer and so make it easier for them to fix it.

Modification:

Correctly set the alert and not always just use a general alert.

Result:

It's easier for the remote peer to fix the problems.

83c4aa6ad8 HTTP/2 Writes GO_AWAY on channelInactive
Motivation:
Http2ConnectionHandler inherits from ByteToMessageDecoder. ByteToMessageDecoder.channelInactive will attempt to decode any remaining data by calling the abstract decode method. If the Http2ConnectionHandler is in server mode, and no data has been exchanged yet, it will try to treat this data as an invalid connection preface and write a GO_AWAY. This is noisy in the logs and creates an illusion that there is a protocol violation when there has not been.

Modifications:
- If the channel is inactive the connection preface decode should not be executed.

Result:
Log files don't include misleading error messages related to connection preface errors.

41d0a81691 Use ByteBufAllocator to allocate ByteBuf for FullHttpMessage Motivation: When converting SPDY or HTTP/2 frames to HTTP/1.x, netty always used an unpooled heap ByteBuf.
Modifications:
When constructing the FullHttpMessage pass in the ByteBuf to use via the ByteBufAllocator assigned via the context.

Result:
The ByteBuf assigned to the FullHttpMessage can now be configured as a pooled/unpooled, direct/heap based ByteBuf via the ByteBufAllocator used.

839e2ca508 Revert JDK GCM direct buffer crash workaround
Motivation:
Commit 108dc23cab introduced a workaround due to a JDK crash when GCM cipher was used during an unwrap operation. Attempting to reproduce this issue with the latest JDK (1.8.0_72-b15) demonstrate that this issue no longer exists while it can be reliably reproduced on earlier JDKs (1.8.0_25-b17 and earlier)

Modifications:
- Remove the copy-to-heap-buffer workaround for JDK engine

0b1c82b254 Ensure read components can be discarded when COMPOSITE_CUMULATOR is used.
Motivation:

ByteToMessageDecoder must ensure that read components of the CompositeByteBuf can be discard by default when discardSomeReadBytes() is called. This may not be the case before as because of the default maxNumComponents that will cause consolidation.

Modifications:

Ensure we not do any consolidation to actually be abel to discard read components

Result:

Less memory usage and allocations.

Modifications:

- Upgrade to netty-tcnative-1.1.33.Fork13
- Skip renegotiate tests if boringssl is used.

Result:

Use newest version of netty-tcnative and be able to build if boringssl is used.

333f55e9ce Add unescapeCsvFields to parse a CSV line and implement CombinedHttpHeaders.getAll
Motivation:

See #4855

Modifications:

Unfortunately, unescapeCsv cannot be used here because the input could be a CSV line like `"a,b",c`. Hence this patch adds unescapeCsvFields to parse a CSV line and split it into multiple fields and unescaped them. The unit tests should define the behavior of unescapeCsvFields.

Then this patch just uses unescapeCsvFields to implement `CombinedHttpHeaders.getAll`.

Result:

`CombinedHttpHeaders.getAll` will return the unescaped values of a header.

b112673554 ByteToMessageDecoder ChannelInputShutdownEvent support
Motivation:
b714297a44 introduced ChannelInputShutdownEvent support for HttpObjectDecoder. However this should have been added to the super class ByteToMessageDecoder, and ByteToMessageDecoder should not propegate a channelInactive event through the pipeline in this case.

Modifications:
- Move the ChannelInputShutdownEvent handling from HttpObjectDecoder to ByteToMessageDecoder
- ByteToMessageDecoder doesn't call ctx.fireChannelInactive() on ChannelInputShutdownEvent

Result:
Half closed events are treated more generically, and don't get translated into a channelInactive pipeline event.

06e29e0d1b HTTP/2 codec may not always call Http2Connection.onStreamRemoved
Motivation:
Http2Connection.onStreamRemoved is not always called if Http2Connection.onStreamAdded is called. This is problematic as users may rely on the onStreamRemoved method to be called to release ByteBuf objects and do other cleanup.

Modifications:
- Http2Connection.close will remove all streams existing streams and prevent new ones from being created
- Http2ConnectionHandler will call the new close method in channelInactive

Result:
Http2Connection.onStreamRemoved is always called when Http2Connection.onStreamRemoved is called to preserve the Http2Connection guarantees.

c6a3729e4c Ensure handlerAdded(...) and handlerRemoved(...) is always called from the right thread
Motiviation:

We should ensure that handlerAdded(...) and handlerRemoved(...) is always called from the EventExecutor that also invokes the other methods of the ChannelHandler. Also we need to ensure we always call handlerAdded(...) before any other method can be calld to ensure correct ordering.

Motifications:

- Ensure that the right thread is used to call the methods
- Ensure correct ordering
- Add tests

Result:

Respect the thread-model for handlerAdded(...) and handlerRemoved(...) and preserve correct ordering in all cases.

fdc6a5e87f Leak Detector disclosing when records dropped
Motivation:
ResourceLeakDetector enforces a limit as to how large the queue is allowed to grow for stack traces in order to keep memory from growing too large. However it is not always clear when records are dropped, or how many have been dropped. This can make interpreting leak reports more difficult if you assume all information is present when it may not be. Also we should increase the limit (currently 4) when running tests on the CI servers.

Modifications:
- Increase leak detector record limit on CI servers from 4 to 32.
- Track how many records have been discarded and disclose this in the leak report.

Result:
Leak reports clarify how many records were dropped, and how to increase the limit.

691bc1690e ByteBufUtil.writeUtf8 not consistent with String.getBytes(Charset)
Motivation:
f750d6e36c added support for surrogates in the writeUtf8 conversion. However exceptions are thrown if invalid input is detected, but the JDK (and slow path of writeUtf8) uses a replacement character and does not throw. We should behave the same way.

Modificiations:
- Don't throw in ByteBufUtil.writeUtf8, and instead use a replacement character consistent with the JDK

Result:
ByteBufUtil.writeUtf8 behavior is consistent with the JDK UTF_8 conversion.

a15ff32608 HttpObjectDecoder configurable initial buffer size
Motivation:
The initial buffer size used to decode HTTP objects is currently fixed at 128. This may be too small for some use cases and create a high amount of overhead associated with resizing/copying. The user should be able to configure the initial size as they please.

Modifications:
- Make HttpObjectDecoder's AppendableCharSequence initial size configurable

Result:
Users can more finely tune initial buffer size for increased performance or to save memory.
