3ee44a3dbb Update Netty to latest netty-tcnative
Motivation:

The latest netty-tcnative fixes a bug in determining the version of the runtime openssl lib.  It also publishes an artificact with the classifier linux-<arch>-fedora for fedora-based systems.

Modifications:

Modified the build files to use the "-fedora" classifier when appropriate for tcnative. Care is taken, however, to not change the classifier for the native epoll transport.

Result:

Netty is updated the the new shiny netty-tcnative.

6e3acfeb06 Correctly throw SSLPeerUnverifiedException if peers identity has not been verified
Motivation:

As stated in the SSLSession javadocs getPeer* methods need to throw a SSLPeerUnverifiedException if peers identity has not be verified.

Modifications:

- Correctly throw SSLPeerUnverifiedException
- Add test for it.

Result:

Correctly behave like descripted in javadocs.

58dc7f7902 Do not bother closing SSL enging inbound if the outbound has already been closed.
Motivation:

Invoking the javax.net.ssl.SSLEngine.closeInbound() method will send a
fatal alert and invalidate the SSL session if a close_notify alert has
not been received.
From the javadoc:
If the application initiated the closing process by calling
closeOutbound(), under some circumstances it is not required that the
initiator wait for the peer's corresponding close message. (See section
7.2.1 of the TLS specification (RFC 2246) for more information on
waiting for closure alerts.) In such cases, this method need not be
called.
Always invoking the closeInbound() method without regard to whether or
not the closeOutbound() method has been invoked could lead to
invalidating perfectly valid SSL sessions.

Modifications:

Added an instance variable to track whether the
SSLEngine.closeOutbound() method has been invoked. When the instance
variable is true, the SSLEngine.closeInbound() method doesn't need to be
invoked.

Result:

SSL sessions will not be invalidated if the outbound side has been
closed but a close_notify alert hasn't been received.

b6a4f5de9d Refactor of HttpUtil and HttpHeaderUtil
Motivation:
There currently exists http.HttpUtil, http2.HttpUtil, and http.HttpHeaderUtil. Having 2 HttpUtil methods can be confusing and the utilty methods in the http package could be consolidated.

Modifications:
- Rename http2.HttpUtil to http2.HttpConversionUtil
- Move http.HttpHeaderUtil methods into http.HttpUtil

Result:
Consolidated utilities whose names don't overlap.

5ac84760c4 Allow to create SslContext from existing PrivateKey / X509Certificate
Motivation:

Sometimes the user already has a PrivateKey / X509Certificate which should be used to create a new SslContext. At the moment we only allow to construct it via Files.

Modifications:

- Add new methods to the SslContextBuilder to allow creating a SslContext from PrivateKey / X509Certificate
- Mark all public constructors of *SslContext as @Deprecated, the user should use SslContextBuilder
- Update tests to us SslContextBuilder.

Result:

Creating of SslContext is possible with PrivateKay/X509Certificate

abaaa75ddc Reduce the memory requirement of heap dump compression
Motivation:

The current heap dump compression preset (9) requires way too much
memory (768 MiB at maximum for dictionary), resulting in OOME in many

6c025b2044 Add support for SCTP 'unordered' flag.
Motivation:

Some SCTP applications require the SCTP unordered flag.
This flag was not exposed by Netty so applications were unable
to use it.

Modifications:

- Add unordered flag to SctpMessage.
- {Nio,Oio}SctpChannel pass unordered flag to MessageInfo on write.
- SctpOutboundByteStreamHandler may optionally request unordered
  delivery for all outbound messages.
- Added test case to SctpEchoTest using unordered flag.

Result:

Fixes #3698. New constructors and methods added to SctpMessage and
SctpOutboundByteStreamHandler, but changes are backward compatible.

Motiviation:

Our tests for non-auto-read did actually not test this correctly as auto-read was never disabled on the Bootstrap and ServerBootstrap.

Modifications:

- Correctly disable auto-read on Bootstrap and ServerBootstrap
- Fix tests to call ChannelHandlerContext.read() once a Channel becomes active.

Result:

Correctly test that non-auto-read works.

afa9e71ed3 Allow to use WebSocketClientHandshaker and WebSocketServerHandshaker with HttpResponse / HttpRequest
Motivation:

To use WebSocketClientHandshaker / WebSocketServerHandshaker it's currently a requirement of having a HttpObjectAggregator in the ChannelPipeline. This is not a big deal when a user only wants to server WebSockets but is a limitation if the server serves WebSockets and normal HTTP traffic.

Modifications:

Allow to use WebSocketClientHandshaker and WebSocketServerHandshaker without HttpObjectAggregator in the ChannelPipeline.

Result:

More flexibility

f771a97592 Add support for Unix Domain Sockets when using native epoll transport
Motivation:

Using Unix Domain Sockets can be very useful when communication should take place on the same host and has less overhead then using loopback. We should support this with the native epoll transport.

Modifications:

- Add support for Unix Domain Sockets.
- Adjust testsuite to be able to reuse tests.

Result:

Unix Domain Sockets are now support when using native epoll transport.

2681112080 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.

682df517c9 Add OpenSslClientContext to allow creating SslEngine for client side
Motivation:

We only support openssl for server side at the moment but it would be also useful for client side.

Modification:

* Upgrade to new netty-tcnative snapshot to support client side openssl support
* Add OpenSslClientContext which can be used to create SslEngine for client side usage
* Factor out common logic between OpenSslClientContext and OpenSslServerContent into new abstract base class called OpenSslContext
* Correctly detect handshake failures as soon as possible
* Guard against segfault caused by multiple calls to destroyPools(). This can happen if OpenSslContext throws an exception in the constructor and the finalize() method is called later during GC

Result:

openssl can be used for client and servers now.

563bf24424 Do not use SLF4J/Logback API directly
Motivation:

TrafficShapingHandlerTest uses Logback API directly, which is
discouraged.  Also, it overrides the global default log level, which
silences the DEBUG messages from other tests.

Modifications:

Remove the direct use of Logback API

Result:

The tests executed after TrafficShapingHandlerTest logs their DEBUG
messages correctly.

c7b407e288 Compress the heap dump after tests are finished
Motivation:

Tests sometimes time out because it took too long to compress the
generated heap dump.

Modifications:

- Move the compression logic to a new method 'compressHeapDumps()'
- Call TestUtils.compressHeapDumps() at the end of the tests, so that
  the tests do not fail because of timeout

Result:

8d4a97e05b Generate non-test JAR for netty-testsuite
Motivation:

So far, we generated and deployed test JARs to Maven repositories. The
deployed JAR had the classifier 'test-jar'.  The test JAR is consumed by
transport-native-epoll as a test dependency.

The problem is, when netty-transport-native-epoll pulls the test JAR as
a dependency, that Maven resolves its transitive dependencies at
'compile' and 'runtime' scope only, which is incorrect.

I was bitten by this problem recently while trying to add a new
dependency to netty-testsuite.  Because I added a new dependency at the
'test' scope, the new dependency was not pulled transitively by
transport-native-epoll and caused an unexpected build failure.

- d6160208c3
- bf77bb4c3a

Modifications:

- Move all classes in netty-testsuite from src/test to src/main
- Update the 'compile' scope dependencies of netty-testsuite
- Override the test directory configuration properties of the surefire
  plugin
- Do not generate the test JAR anymore
- Update the dependency of netty-transport-native-epoll

Result:

It is less error-prone to add a new dependency to netty-testsuite.

Motivation:

Modifications:

Result:

dump file is about 3 times smaller than before, although the compression
time will increase the build time when the test fails.

e72b2235fb Make sure to notify handshake success even if SSLEngine is closed
Related:

e9685ea45a

Motivation:

SslHandler.unwrap() does not evaluate the handshake status of
SSLEngine.unwrap() when the status of SSLEngine.unwrap() is CLOSED.

It is not correct because the status does not reflect the state of the
handshake currently in progress, accoding to the API documentation of
SSLEngineResult.Status.

Also, sslCloseFuture can be notified earlier than handshake notification
because we call sslCloseFuture.trySuccess() before evaluating handshake
status.

Modifications:

- Notify sslCloseFuture after the unwrap loop is finished
- Add more assertions to SocketSslEchoTest

Result:

Potentially fix the regression caused by:

Related: #3125

Motivation:

We did not expose a way to initiate TLS renegotiation and to get

Modifications:

- Add SslHandler.renegotiate() so that a user can initiate TLS
  renegotiation and get the future that's notified on completion
- Make SslHandler.handshakeFuture() return the future for the most
  recent handshake so that a user can get the future of the last
  renegotiation
- Add the test for renegotiation to SocketSslEchoTest

Result:

Both client-initiated and server-initiated renegotiations are now

4ce994dd4f Fix backward compatibility from the previous backport
Motivation:

The commit 50e06442c3 changed the type of
the constants in HttpHeaders.Names and HttpHeaders.Values, making 4.1
backward-incompatible with 4.0.

It also introduces newer utility classes such as HttpHeaderUtil, which
deprecates most static methods in HttpHeaders.  To ease the migration
between 4.1 and 5.0, we should deprecate all static methods that are
non-existent in 5.0, and provide proper counterpart.

Modification:

- Revert the changes in HttpHeaders.Names and Values
- Deprecate all static methods in HttpHeaders in favor of:
  - HttpHeaderUtil
  - the member methods of HttpHeaders
  - AsciiString
- Add integer and date access methods to HttpHeaders for easier future
  migration to 5.0
- Add HttpHeaderNames and HttpHeaderValues which provide standard HTTP
  constants in AsciiString
  - Deprecate HttpHeaders.Names and Values
  - Make HttpHeaderValues.WEBSOCKET lowercased because it's actually
    lowercased in all WebSocket versions but the oldest one
- Add RtspHeaderNames and RtspHeaderValues which provide standard RTSP
  constants in AsciiString
  - Deprecate RtspHeaders.*
- Do not use AsciiString.equalsIgnoreCase(CharSeq, CharSeq) if one of
  the parameters are AsciiString
- Avoid using AsciiString.toString() repetitively
  - Change the parameter type of some methods from String to
    CharSequence

Result:

Backward compatibility is recovered.  New classes and methods will make
the migration to 5.0 easier, once (Http|Rtsp)Header(Names|Values) are
ported to master.

e848066cab Name resolver API and DNS-based name resolver
Motivation:

So far, we relied on the domain name resolution mechanism provided by
JDK.  It served its purpose very well, but had the following
shortcomings:

- Domain name resolution is performed in a blocking manner.
  This becomes a problem when a user has to connect to thousands of
  different hosts. e.g. web crawlers
- It is impossible to employ an alternative cache/retry policy.
  e.g. lower/upper bound in TTL, round-robin
- It is impossible to employ an alternative name resolution mechanism.
  e.g. Zookeeper-based name resolver

Modification:

- Add the resolver API in the new module: netty-resolver
- Implement the DNS-based resolver: netty-resolver-dns
  .. which uses netty-codec-dns
- Make ChannelFactory reusable because it's now used by
  io.netty.bootstrap, io.netty.resolver.dns, and potentially by other
  modules in the future
  - Move ChannelFactory from io.netty.bootstrap to io.netty.channel
  - Deprecate the old ChannelFactory
  - Add ReflectiveChannelFactory

Result:

It is trivial to resolve a large number of domain names asynchronously.

9428d51e2f Add support for sendmmsg(...) and so allow to write multiple DatagramPackets with one syscall. Related to [#2719]
Motivation:

On linux with glibc >= 2.14 it is possible to send multiple DatagramPackets with one syscall. This can be a huge performance win and so we should support it in our native transport.

Modification:

- Add support for sendmmsg by reuse IovArray
- Factor out ThreadLocal support of IovArray to IovArrayThreadLocal for better separation as we use IovArray also without ThreadLocal in NativeDatagramPacketArray now
- Introduce NativeDatagramPacketArray which is used for sendmmsg(...)
- Implement sendmmsg(...) via jni
- Expand DatagramUnicastTest to test also sendmmsg(...)

Result:

Netty now automatically use sendmmsg(...) if it is supported and we have more then 1 DatagramPacket in the ChannelOutboundBuffer and flush() is called.

88c273364d Fix for issue #2765 relative to unstable trafficshaping test procedure
Motivation:

The test procedure is unstable due to not enough precise timestamping
during the check.

Modifications:

Reducing the test cases and cibling "stable" test ("timestamp-able")
bring more stability to the tests.

Result:

Tests for TrafficShapingHandler seem more stable (whatever using JVM 6,
7 or 8).

dcfdad9e9e [#2769] Fix regression when writing different message types
Motivation:

Due a regression NioSocketChannel.doWrite(...) will throw a ClassCastException if you do something like:

channel.write(bytebuf);
channel.write(fileregion);
channel.flush();

Modifications:

Correctly handle writing of different message types by using the correct message count while loop over them.

Result:

No more ClassCastException

061d5bc261 Fix data corruption in FileRegion transfer with epoll transport
Related issue: #2764

Motivation:

EpollSocketChannel.writeFileRegion() does not handle the case where the
position of a FileRegion is non-zero properly.

Modifications:

- Improve SocketFileRegionTest so that it tests the cases where the file
  transfer begins from the middle of the file
- Add another jlong parameter named 'base_off' so that we can take the
  position of a FileRegion into account

Result:

Improved test passes. Corruption is gone.

bc1379d19d [#2721] Improve Traffic Shaping handler
Motivation:
Currently Traffic Shaping is using 1 timer only and could lead to
"partial" wrong bandwidth computation when "short" time occurs between
adding used bytes and when the TrafficCounter updates itself and finally
when the traffic is computed.
Indeed, the TrafficCounter is updated every x delay and it is at the
same time saved into "lastXxxxBytes" and set to 0. Therefore, when one
request the counter, it first updates the TrafficCounter with the added
used bytes. If this value is set just before the TrafficCounter is
updated, then the bandwidth computation will use the TrafficCounter with
a "0" value (this value being reset once the delay occurs). Therefore,
the traffic shaping computation is wrong in rare cases.

Secondly the traffic shapping should avoid if possible the "Timeout"
effect by not stopping reading or writing more than a maxTime, this
maxTime being less than the TimeOut limit.

Thirdly the traffic shapping in read had an issue since the readOp
was not set but should, turning in no read blocking from socket
point of view.

Modifications:
The TrafficCounter has 2 new methods that compute the time to wait
according to read or write) using in priority the currentXxxxBytes (as
before), but could used (if current is at 0) the lastXxxxxBytes, and
therefore having more chance to take into account the real traffic.

Moreover the Handler could change the default "max time to wait", which
is by default set to half of "standard" Time Out (30s:2 = 15s).

Finally we add the setAutoRead(boolean) accordingly to the situation,
as proposed in #2696 (this pull request is in error for unknown reason).

Result:
The Traffic Shaping is better take into account (no 0 value when it
shouldn't) and it tries to not block traffic more than Time Out event.

Moreover the read is really stopped from socket point of view.

This version is similar to #2388 and #2450.
This version is for V4.1, and includes the #2696 pull request
to ease the merge process.
It is compatible with master too.

Including also #2748

The test minimizes time check by reducing to 66ms steps (55s).

fb22d34925 [#2647] Respect IOV_MAX when call writev in native transport
Motivation:

epoll transport fails on gathering write of more then 1024 buffers. As linux supports max. 1024 iov entries when calling writev(...) the epoll transport throws an exception.

Thanks again to @blucas to provide me with a reproducer and so helped me to understand what the issue is.

Modifications:

Make sure we break down the writes if to many buffers are uses for gathering writes.

Result:

Gathering writes work with any number of buffers

8b0a0f9a8f Introduce MessageAggregator and DecoderResultProvider
Motivation:

We have different message aggregator implementations for different
protocols, but they are very similar with each other.  They all stems
from HttpObjectAggregator.  If we provide an abstract class that provide
generic message aggregation functionality, we will remove their code
duplication.

Modifications:

- Add MessageAggregator which provides generic message aggregation
- Reimplement all existing aggregators using MessageAggregator
- Add DecoderResultProvider interface and extend it wherever possible so
  that MessageAggregator respects the state of the decoded message

Result:

Less code duplication

b6c0c0c95f Add an OpenSslEngine and the universal API for enabling SSL
Motivation:

Some users already use an SSLEngine implementation in finagle-native. It
wraps OpenSSL to get higher SSL performance.  However, to take advantage
of it, finagle-native must be compiled manually, and it means we cannot
pull it in as a dependency and thus we cannot test our SslHandler
against the OpenSSL-based SSLEngine.  For an instance, we had #2216.

Because the construction procedures of JDK SSLEngine and OpenSslEngine
are very different from each other, we also need to provide a universal
way to enable SSL in a Netty application.

Modifications:

- Pull netty-tcnative in as an optional dependency.
  http://netty.io/wiki/forked-tomcat-native.html
- Backport NativeLibraryLoader from 4.0
- Move OpenSSL-based SSLEngine implementation into our code base.
  - Copied from finagle-native; originally written by @jpinner et al.
  - Overall cleanup by @trustin.
- Run all SslHandler tests with both default SSLEngine and OpenSslEngine
- Add a unified API for creating an SSL context
  - SslContext allows you to create a new SSLEngine or a new SslHandler
    with your PKCS#8 key and X.509 certificate chain.
  - Add JdkSslContext and its subclasses
  - Add OpenSslServerContext
- Add ApplicationProtocolSelector to ensure the future support for NPN
  (NextProtoNego) and ALPN (Application Layer Protocol Negotiation) on
  the client-side.
- Add SimpleTrustManagerFactory to help a user write a
  TrustManagerFactory easily, which should be useful for those who need
  to write an alternative verification mechanism. For example, we can
  use it to implement an unsafe TrustManagerFactory that accepts
  self-signed certificates for testing purposes.
- Add InsecureTrustManagerFactory and FingerprintTrustManager for quick
  and dirty testing
- Add SelfSignedCertificate class which generates a self-signed X.509
  certificate very easily.
- Update all our examples to use SslContext.newClient/ServerContext()
- SslHandler now logs the chosen cipher suite when handshake is
  finished.

Result:

- Cleaner unified API for configuring an SSL client and an SSL server
  regardless of its internal implementation.
- When native libraries are available, OpenSSL-based SSLEngine
  implementation is selected automatically to take advantage of its
  performance benefit.
- Examples take advantage of this modification and thus are cleaner.

20ef4690e7 [#2375] [#2404] Fix bug in respecting ChannelConfig.setAutoRead(false) and also fix Channel.read() for OIO
Motivation:
At the moment ChanneConfig.setAutoRead(false) only is guaranteer to not have an extra channelRead(...) triggered when used from within the channelRead(...) or channelReadComplete(...) method. This is not the correct behaviour as it should also work from other methods that are triggered from within the EventLoop. For example a valid use case is to have it called from within a ChannelFutureListener, which currently not work as expected.

Beside this there is another bug which is kind of related. Currently Channel.read() will not work as expected for OIO as we will stop try to read even if nothing could be read there after one read operation on the socket (when the SO_TIMEOUT kicks in).

Modifications:
Implement the logic the right way for the NIO/OIO/SCTP and native transport, specific to the transport implementation. Also correctly handle Channel.read() for OIO transport by trigger a new read if SO_TIMEOUT was catched.

Result:
It is now also possible to use ChannelConfig.setAutoRead(false) from other methods that are called from within the EventLoop and have direct effect.

7808b9926d SPDY: refactor frame codec implementation
Motivation:

Currently, the SPDY frame encoding and decoding code is based upon
the ChannelHandler abstraction. This requires maintaining multiple
versions for 3.x and 4.x (and possibly 5.x moving forward).

Modifications:

The SPDY frame encoding and decoding code is separated from the
ChannelHandler and SpdyFrame abstractions. Also test coverage is
improved.

Result:

SpdyFrameCodec now implements the ChannelHandler abstraction and is
responsible for creating and handling SpdyFrame objects.

c87db9b17a Reduce SO_TIMEOUT of testsuite so it finishes sooner
Motivation:

Testing the OIO transport takes longer time than other transports because it has to wait for SO_TIMEOUT if there is nothing to read.  In production, it's not a good idea to decrease this value (1000ms) because it will result in so many SocketTimeoutExceptions internally, but doing so in the testsuite should be fine.

Modifications:

Reduce the default SO_TIMEOUT of OIO channels to 10 ms.

Result:

Our testsuite finishes sooner.

bd9ad4b532 Perform cross-tests between NIO and epoll transport
Motivation:

The epoll testsuite tests the epoll transport only against itself (i.e. epoll x epoll only).  We should test the epoll transport also against the well-tested NIO transport, too.

Modifications:

- Make SocketTestPermutation extensible and reusable so that the epoll testsuite can take advantage of it.
- Rename EpollTestUtils to EpollSocketTestPermutation and make it extend SocketTestPermutation.
- Overall clean-up of SocketTestPermutation
  - Use Arrays.asList() for simplicity
  - Add combo() method to remove code duplication

Result:

The epoll transport is now also tested against the NIO transport.  SocketTestPermutation got cleaner.

2de65e25e9 Set timeout for SocketSslEchoTest
Motivation:

We are seeing EpollSocketSslEchoTest does not finish itself while its I/O thread is busy.  Jenkins should have terminated them when the global build timeout reaches, but Jenkins seems to fail to do so.  What's more interesting is that Jenkins will start another job before the EpollSocketSslEchoTest is terminated, and Linux starts to oom-kill them, impacting the uptime of the CI service.

Modifications:

- Set timeout for all test cases in SocketSslEchoTest so that all SSL tests terminate themselves when they take too long.
- Fix a bug where the epoll testsuite uses non-daemon threads which can potentially prevent JVM from quitting.
- (Cleanup) Separate boss group and worker group just like we do for NIO/OIO transport testsuite.

Result:

Potentially more stable CI machine.

b57d9f307f Allow per-write promises and disallow promises on flush()
- write() now accepts a ChannelPromise and returns ChannelFuture as most
  users expected.  It makes the user's life much easier because it is
  now much easier to get notified when a specific message has been
  written.
- flush() does not create a ChannelPromise nor returns ChannelFuture.
  It is now similar to what read() looks like.

We renamed messageReceivedLast to channelReadComplete because it

cbd8817905 Remove MessageList from public API and change ChannelInbound/OutboundHandler accordingly
I must admit MesageList was pain in the ass.  Instead of forcing a
handler always loop over the list of messages, this commit splits
messageReceived(ctx, list) into two event handlers:

- messageReceived(ctx, msg)
- mmessageReceivedLast(ctx)

When Netty reads one or more messages, messageReceived(ctx, msg) event
is triggered for each message.  Once the current read operation is
finished, messageReceivedLast() is triggered to tell the handler that
the last messageReceived() was the last message in the current batch.

Similarly, for outbound, write(ctx, list) has been split into two:

- write(ctx, msg)
- flush(ctx, promise)

Instead of writing a list of message with a promise, a user is now
supposed to call write(msg) multiple times and then call flush() to
actually flush the buffered messages.

Please note that write() doesn't have a promise with it.  You must call
flush() to get notified on completion. (or you can use writeAndFlush())

Other changes:

- Because MessageList is completely hidden, codec framework uses
  List<Object> instead of MessageList as an output parameter.

The AIO transport was added in the past as we hoped it would have better latency as the NIO transport. But in reality this was never the case.
So there is no reason to use the AIO transport at all. It just put more burden on us as we need to also support it and fix bugs.
Because of this we dedicided to remove it for now. It will stay in the master_with_aio_transport branch so we can pick it up later again if it is ever needed.

14158070bf Revamp the core API to reduce memory footprint and consumption
The API changes made so far turned out to increase the memory footprint
and consumption while our intention was actually decreasing them.

Memory consumption issue:

When there are many connections which does not exchange data frequently,
the old Netty 4 API spent a lot more memory than 3 because it always
allocates per-handler buffer for each connection unless otherwise
explicitly stated by a user.  In a usual real world load, a client
doesn't always send requests without pausing, so the idea of having a
buffer whose life cycle if bound to the life cycle of a connection
didn't work as expected.

Memory footprint issue:

The old Netty 4 API decreased overall memory footprint by a great deal
in many cases.  It was mainly because the old Netty 4 API did not
allocate a new buffer and event object for each read.  Instead, it
created a new buffer for each handler in a pipeline.  This works pretty
well as long as the number of handlers in a pipeline is only a few.
However, for a highly modular application with many handlers which
handles connections which lasts for relatively short period, it actually
makes the memory footprint issue much worse.

Changes:

All in all, this is about retaining all the good changes we made in 4 so
far such as better thread model and going back to the way how we dealt
with message events in 3.

To fix the memory consumption/footprint issue mentioned above, we made a
hard decision to break the backward compatibility again with the
following changes:

- Remove MessageBuf
- Merge Buf into ByteBuf
- Merge ChannelInboundByte/MessageHandler and ChannelStateHandler into ChannelInboundHandler
  - Similar changes were made to the adapter classes
- Merge ChannelOutboundByte/MessageHandler and ChannelOperationHandler into ChannelOutboundHandler
  - Similar changes were made to the adapter classes
- Introduce MessageList which is similar to `MessageEvent` in Netty 3
- Replace inboundBufferUpdated(ctx) with messageReceived(ctx, MessageList)
- Replace flush(ctx, promise) with write(ctx, MessageList, promise)
- Remove ByteToByteEncoder/Decoder/Codec
  - Replaced by MessageToByteEncoder<ByteBuf>, ByteToMessageDecoder<ByteBuf>, and ByteMessageCodec<ByteBuf>
- Merge EmbeddedByteChannel and EmbeddedMessageChannel into EmbeddedChannel
- Add SimpleChannelInboundHandler which is sometimes more useful than
  ChannelInboundHandlerAdapter
- Bring back Channel.isWritable() from Netty 3
- Add ChannelInboundHandler.channelWritabilityChanges() event
- Add RecvByteBufAllocator configuration property
  - Similar to ReceiveBufferSizePredictor in Netty 3
  - Some existing configuration properties such as
    DatagramChannelConfig.receivePacketSize is gone now.
- Remove suspend/resumeIntermediaryDeallocation() in ByteBuf

This change would have been impossible without @normanmaurer's help. He
fixed, ported, and improved many parts of the changes.

23d0178494 Introduce EventExecutor.shutdownGracefully() that deprecates shutdown()
shutdownGracefully() provides two optional parameters that give more
control over when an executor has to be shut down.

- Related issue: #1307
- Add shutdownGracefully(..) and isShuttingDown()
- Deprecate shutdown() / shutdownNow()
- Replace lastAccessTime with lastExecutionTime and update it after task
  execution for accurate quiet period check
  - runAllTasks() and runShutdownTasks() update it automatically.
  - Add updateLastExecutionTime() so that subclasses can update it
- Add a constructor parameter that tells not to add an unncessary wakeup
  task in execute() if addTask() wakes up the executor thread
  automatically.  Previously, execute() always called wakeup() after
  addTask(), which often caused an extra dummy task in the task queue.
- Use shutdownGracefully() wherever possible / Deprecation javadoc
- Reduce the running time of SingleThreadEventLoopTest from 40s to 15s
  using custom graceful shutdown parameters

- Other changes made along with this commit:
  - takeTask() does not throw InterruptedException anymore.
    - Returns null on interruption or wakeup
  - Make sure runShutdownTasks() return true even if an exception was
    raised while running the shutdown tasks

- Fixes #1308

freeInboundBuffer() and freeOutboundBuffer() were introduced in the early days of the new API when we did not have reference counting mechanism in the buffer. A user did not want Netty to free the handler buffers had to override these methods.

However, now that we have reference counting mechanism built into the buffer, a user who wants to retain the buffers beyond handler's life cycle can simply return the buffer whose reference count is greater than 1 in newInbound/OutboundBuffer().

0909878581 Read only when requested (read-on-demand)
This pull request introduces a new operation called read() that replaces the existing inbound traffic control method. EventLoop now performs socket reads only when the read() operation has been issued. Once the requested read() operation is actually performed, EventLoop triggers an inboundBufferSuspended event that tells the handlers that the requested read() operation has been performed and the inbound traffic has been suspended again. A handler can decide to continue reading or not.

Unlike other outbound operations, read() does not use ChannelFuture at all to avoid GC cost. If there's a good reason to create a new future per read at the GC cost, I'll change this.

This pull request consequently removes the readable property in ChannelHandlerContext, which means how the traffic control works changed significantly.

This pull request also adds a new configuration property ChannelOption.AUTO_READ whose default value is true. If true, Netty will call ctx.read() for you. If you need a close control over when read() is called, you can set it to false.

Another interesting fact is that non-terminal handlers do not really need to call read() at all. Only the last inbound handler will have to call it, and that's just enough. Actually, you don't even need to call it at the last handler in most cases because of the ChannelOption.AUTO_READ mentioned above.

There's no serious backward compatibility issue. If the compiler complains your handler does not implement the read() method, add the following:

public void read(ChannelHandlerContext ctx) throws Exception {
    ctx.read();

Note that this pull request certainly makes bounded inbound buffer support very easy, but itself does not add the bounded inbound buffer support.

e59ac8e79b Do not call inbound event methods directly
- Fixes #831

This commit ensures the following events are never triggered as a direct
invocation if they are triggered via ChannelPipeline.fire*():

- channelInactive
- channelUnregistered
- exceptionCaught

This commit also fixes the following issues surfaced by this fix:

- Embedded channel implementations run scheduled tasks too early
- SpdySessionHandlerTest tries to generate inbound data even after the
  channel is closed.
- AioSocketChannel enters into an infinite loop on I/O error.

b47fc77522 Add PooledByteBufAllocator + microbenchmark module
This pull request introduces the new default ByteBufAllocator implementation based on jemalloc, with a some differences:

* Minimum possible buffer capacity is 16 (jemalloc: 2)
* Uses binary heap with random branching (jemalloc: red-black tree)
* No thread-local cache yet (jemalloc has thread-local cache)
* Default page size is 8 KiB (jemalloc: 4 KiB)
* Default chunk size is 16 MiB (jemalloc: 2 MiB)
* Cannot allocate a buffer bigger than the chunk size (jemalloc: possible) because we don't have control over memory layout in Java. A user can work around this issue by creating a composite buffer, but it's not always a feasible option. Although 16 MiB is a pretty big default, a user's handler might need to deal with the bounded buffers when the user wants to deal with a large message.

Also, to ensure the new allocator performs good enough, I wrote a microbenchmark for it and made it a dedicated Maven module. It uses Google's Caliper framework to run and publish the test result (example)

Miscellaneous changes:

* Made some ByteBuf implementations public so that those who implements a new allocator can make use of them.
* Added ByteBufAllocator.compositeBuffer() and its variants.
* ByteBufAllocator.ioBuffer() creates a buffer with 0 capacity.
