d79e4ffe07 [#3112] Add supprt for TCP_INFO when using EpollSocketChannel
Motivation:

On Linux, you can gather various metrics using getsockopt(..., TCP_INFO,
...).

Modifications:

Add EpollSocketChannel.tcpInfo() which returns EpollTcpInfo that exposes
all metrics exposed via getsockopt(..., TCP_INFO, ...)

Result:

TCP_INFO support implemented

ded37d8893 Zlib decoder calls reduction and index fix
Motivation:
The JdkZlibDecoder and JZlibDecoder call isReadable and readableBytes in the same method. There is an opportunity to reduce the number of methods calls to just use readableBytes.  JdkZlibDecoder reads from a ByteBuf with an absolute index instead of using readerIndex()

Modifications:
- Use readableBytes where isReadable was used
- Correct absolute ByteBuf index to be relative to readerIndex()

Result:
Less method calls duplicating work and preventing an index out of bounds exception.

0d58d07bbf Fix NPE when remote address can not be obtained
Motivation:

In the native transport we use getpeername to obtain the remote address from the file descriptor. This may fail for various reasons in which case NULL is returned.

Modifications:

- Check for null when try to obtain remote / local address

Result:

No more NPE

375b9e1307 Ensure ctx.fireChannelReadComplete() is only called when something was produced
Motivation:

ctx.fireChannelReadComplete() should only be called if something is produced during a channelRead(...) operation. Also we must ensure that it will be called
if channelRead(...) produced something at some point as channelRead(...) maybe called multiple times by the transport before channelReadComplete(...) is called.

Modifications:

- Ensure channelReadComplete(...) only triggers ctx.fireChannelReadComplete() when a previous channelRead(...) call produced a message
- Ensure read() is called of more data is needed

Result:

Correct semantic with channelReadComplete(...) events and also ensure no stales

c910dc61e3 Fixed several issues with HttpContentDecoder
Motivation:

HttpContentDecoder had the following issues:
- For chunked content, the decoder set invalid "Content-Length" header
	with length of the first decoded chunk.
- Decoding of FullHttpRequests put both the original conent and decoded
	content into output. As result, using HttpObjectAggregator before the
	decoder lead to errors.
- Requests with "Expect: 100-continue" header were not acknowleged:
	the decoder didn't pass the header message down the handler's chain
	until content is received. If client expected "100 Continue" response,
	deadlock happened.

Modification:

- Invalid "Content-Length" header is removed; handlers down the chain can either
	rely on LastHttpContent message or ask HttpObjectAggregator to add the header.
- FullHttpRequest is split into HttpRequest and HttpContent (decoded) parts.
- Header (HttpRequest) part of request is sent down the chain as soon as it's received.

Result:

The issues are fixed, unittest is added.

fb0c78885f Fix IndexOutOfBoundsException from SslHandler on JDK 8
Motivation:

When SslHandler.unwrap() copies SSL records into a heap buffer, it does
not update the start offset, causing IndexOutOfBoundsException.

Modifications:

- Copy to a heap buffer before calling unwrap() for simplicity
- Do not copy an empty buffer to a heap buffer.
  - unwrap(... EMPTY_BUFFER ...) never involves copying now.
- Use better parameter names for unwrap()
- Clean-up log messages

Result:

- Bugs fixed
- Cleaner code

f46a3d74d0 Reduce memory copies when using OpenSslEngine with SslHandler
Motivation:

When using OpenSslEngine with the SslHandler it is possible to reduce memory copies by unwrap(...) multiple ByteBuffers at the same time. This way we can eliminate a memory copy that is needed otherwise to cumulate partial received data.

Modifications:

- Add OpenSslEngine.unwrap(ByteBuffer[],...) method that can be used to unwrap multiple src ByteBuffer a the same time
- Use a CompositeByteBuffer in SslHandler for inbound data so we not need to memory copy
- Add OpenSslEngine.unwrap(ByteBuffer[],...) in SslHandler if OpenSslEngine is used and the inbound ByteBuf is backed by more then one ByteBuffer
- Reduce object allocation

Result:

SslHandler is faster when using OpenSslEngine and produce less GC

017a5ef4e4 SPDY: fix support for pushed resources in SpdyHttpEncoder
Motivation:

The SpdyHttpDecoder was modified to support pushed resources that are
divided into multiple frames. The decoder accepts a pushed
SpdySynStreamFrame containing the request headers, followed by a
SpdyHeadersFrame containing the response headers.

Modifications:

This commit modifies the SpdyHttpEncoder so that it encodes pushed
resources in a format that the SpdyHttpDecoder can decode. The encoder
will accept an HttpRequest object containing the request headers,
followed by an HttpResponse object containing the response headers.

Result:

The SpdyHttpEncoder will create a SpdySynStreamFrame followed by a
SpdyHeadersFrame when sending pushed resources.

feacf128ca Eliminate memory copy in ByteToMessageDecoder whenever possible
Motivation:

Currently when there are bytes left in the cumulation buffer we do a byte copy to produce the input buffer for the decode method. This can put quite some overhead on the impl.

Modification:

- Use a CompositeByteBuf to eliminate the byte copy.
- Allow to specify if a CompositeBytebug should be used or not as some handlers can only act on one ByteBuffer in an efficient way (like SslHandler :( ).

Result:

Performance improvement as shown in the following benchmark.

851ca79ea6 Fix for Issue #3308 related to slice missing retain
Motivations:
It seems that slicing a buffer and using this slice to write to CTX will
decrease the initial refCnt to 0, while the original buffer is not yet
fully used (not empty).

Modifications:
As suggested in the ticket and tested, when the currentBuffer is sliced
since it will still be used later on, the currentBuffer is retained.

Add a test case for this issue.

Result::
The currentBuffer still has its correct refCnt when reaching the last
write (not sliced) of 1 and therefore will be released correctly.
The exception does no more occur.

This fix should be applied to all branches >= 4.0.

1c30c8eced Throw exceptions outside the native code
Rebased and cleaned-up based on the work by @normanmaurer

Motivation:

Currently, IOExceptions and ClosedChannelExceptions are thrown from
inside the JNI methods. Instantiation of Java objects inside JNI code is
an expensive operation, needless to say about filling stack trace for
every instantiation of an exception.

Modifications:

Change most JNI methods to return a negative value on failure so that
the exceptions are instantiated outside the native code.

Also, pre-instantiate some commonly-thrown exceptions for better
performance.

b886c056bc Fix big transfer and Write traffic shaping issues
Motivation:

Several issues were shown by various ticket (#2900 #2956).
Also use the improvement on writability user management from #3036.
And finally add a mixte handler, both for Global and Channels, with
the advantages of being uniquely created and using less memory and
less shaping.

Issue #2900

When a huge amount of data are written, the current behavior of the
TrafficShaping handler is to limit the delay to 15s, whatever the delay
the previous write has. This is wrong, and when a huge amount of writes
are done in a short time, the traffic is not correctly shapened.

Moreover, there is a high risk of OOM if one is not using in his/her own
handler for instance ChannelFuture.addListener() to handle the write
bufferisation in the TrafficShapingHandler.

This fix use the "user-defined writability flags" from #3036 to
allow the TrafficShapingHandlers to "user-defined" managed writability
directly, as for reading, thus using the default isWritable() and
channelWritabilityChanged().
This allows for instance HttpChunkedInput to be fully compatible.

The "bandwidth" compute on write is only on "acquired" write orders, not
on "real" write orders, which is wrong from statistic point of view.

Issue #2956

When using GlobalTrafficShaping, every write (and read) are
synchronized, thus leading to a drop of performance.
ChannelTrafficShaping is not touched by this issue since synchronized is
then correct (handler is per channel, so the synchronized).

Modifications:
The current write delay computation takes into account the previous
write delay and time to check is the 15s delay (maxTime) is really
exceeded or not (using last scheduled write time). The algorithm is
simplified and in the same time more accurate.

This proposal uses the #3036 improvement on user-defined writability
flags.

When the real write occurs, the statistics are update accordingly on a
new attribute (getRealWriteThroughput()).

To limit the synchronisations, all synchronized on
GlobalTrafficShapingHandler on submitWrite were removed. They are
replaced with a lock per channel (since synchronization is still needed
to prevent unordered write per channel), as in the sendAllValid method
for the very same reason.
Also all synchronized on TrafficCounter on read/writeTimeToWait() are
removed as they are unnecessary since already locked before by the
caller.
Still the creation and remove operations on lock per channel (PerChannel
object) are synchronized to prevent concurrency issue on this critical
part, but then limited.

Additionnal changes:
1) Use System.nanoTime() instead of System.currentTimeMillis() and
minimize calls
2) Remove / 10 ° 10 since no more sleep usage
3) Use nanoTime instead of currentTime such that time spend is computed,
not real time clock. Therefore the "now" relative time (nanoTime based)
is passed on all sub methods.
4) Take care of removal of the handler to force write all pending writes
and release read too
8) Review Javadoc to explicit:

- recommandations to take into account isWritable

- recommandations to provide reasonable message size according to
traffic shaping limit

- explicit "best effort" traffic shaping behavior when changing
configuration dynamically

Add a MixteGlobalChannelTrafficShapingHandler which allows to use only one
handler for mixing Global and Channel TSH. I enables to save more memory and
tries to optimize the traffic among various channels.

Result:
The traffic shaping is more stable, even with a huge number of writes in
short time by taking into consideration last scheduled write time.

The current implementation of TrafficShapingHandler using user-defined
writability flags and default isWritable() and
fireChannelWritabilityChanged works as expected.

The statistics are more valuable (asked write vs real write).

The Global TrafficShapingHandler should now have less "global"
synchronization, hoping to the minimum, but still per Channel as needed.

The GlobalChannel TrafficShapingHandler allows to have only one handler for all channels while still offering per channel in addition to global traffic shaping.

And finally maintain backward compatibility.

61a5e60513 Provide helper methods in ByteBufUtil to write UTF-8/ASCII CharSequences. Related to [#909]
Motivation:

We expose no methods in ByteBuf to directly write a CharSequence into it. This leads to have the user either convert the CharSequence first to a byte array or use CharsetEncoder. Both cases have some overheads and we can do a lot better for well known Charsets like UTF-8 and ASCII.

Modifications:

Add ByteBufUtil.writeAscii(...) and ByteBufUtil.writeUtf8(...) which can do the task in an optimized way. This is especially true if the passed in ByteBuf extends AbstractByteBuf which is true for all of our implementations which not wrap another ByteBuf.

Result:

Writing an ASCII and UTF-8 CharSequence into a AbstractByteBuf is a lot faster then what the user could do by himself as we can make use of some package private methods and so eliminate reference and range checks. When the Charseq is not ASCII or UTF-8 we can still do a very good job and are on par in most of the cases with what the user would do.

The following benchmark shows the improvements:

54a27ef07e Fix NoClassDefFoundError when netty-tcnative is unavailable
Motivation:

ProxyHandlerTest fails with NoClassDefFoundError raised by
SslContext.newClientContext().

Modifications:

Fix a missing 'return' statement that makes the switch-case block fall
through unncecessarily

Result:

- ProxyHandlerTest does not fail anymore.
- SslContext.newClientContext() does not raise NoClassDefFoundError
  anymore.

0dca08ab12 HttpObjectAggregator only set Content-Length is not already set.
Motivation:

HEAD requests will have a Content-Length set that doesn't match the
actual length. So we only want to set Content-Length header if it isn't
already set.

Modifications:

If check around setting the Content-Length.

Result:

A HEAD request will no correctly return the specified Content-Length
instead of the body length.

eeb5e2c0a9 Check for errors without object allocation
Motivation:

At the moment we use SSL.getLastError() in unwrap(...) to check for error. This is very inefficient as it creates a new String for each check and we also use a String.startsWith(...) to detect if there was an error we need to handle.

Modifications:

Use SSL.getLastErrorNumber() to detect if we need to handle an error, as this only returns a long and so no String creation happens. Also the detection is much cheaper as we can now only compare longs. Once an error is detected the lately SSL.getErrorString(long) is used to conver the error number to a String and include it in log and exception message.

Result:

Performance improvements in OpenSslEngine.unwrap(...) due less object allocation and also faster comparations.
