a79b69adf5 ChannelFlushPromiseNotifier should allow long value for pendingDataSize
Motivation:
At the moment ChannelFlushPromiseNotifier.add(....) takes an int value for pendingDataSize, which may be too small as a user may need to use a long. This can for example be useful when a user writes a FileRegion etc. Beside this the notify* method names are kind of missleading as these should not contain *Future* because it is about ChannelPromises.

Modification:
Add a new add(...) method that takes a long for pendingDataSize and @deprecated the old method. Beside this also @deprecated all *Future* methods and add methods that have *Promise* in the method name to better reflect usage.

Result:
ChannelFlushPromiseNotifier can be used with bigger data.

c1d6ba0598 OkResponseHandler should return a FullHttpResponse.
Motivation:
Currently OkResponseHandler returns a DefaultHttpResponse which is not
correct and it should be returning complete http response.

Modifications:
Updated OkResponseHandler to return an instance of
DefaultFullHttpResponse.

Result:
It is not possible to add compression to the example without getting any
errors.

eb27cd279c [#2494] Fix data curruption by ChannelTrafficShapingHandler
Motivation:
ChannelTrafficShapingHandler may corrupt inbound data stream by
scheduling the fireChannelRead event.

Modification:
Always call fireChannelRead(...) and only suspend reads after it

Result:
No more data corruption

13c0cfde59 Add awaitInactivity() to GlobalEventExecutor and ThreadDeathWatcher
Motivation:

When running Netty on a container environment, the container will often
complain about the lingering threads such as the worker threads of
ThreadDeathWatcher and GlobalEventExecutor.  We should provide an
operation that allows a use to wait until such threads are terminated.

Modifications:

- Add awaitInactivity()
- (misc) Fix typo in GlobalEventExecutorTest
- (misc) Port ThreadDeathWatch's CAS-based thread life cycle management
  to GlobalEventExecutor

Result:

- Fixes #2084
- Less overhead on task submission of GlobalEventExecutor

e79ca269b8 Introduce ThreadDeathWatcher
Motivation:

PooledByteBufAllocator's thread local cache and
ReferenceCountUtil.releaseLater() are in need of a way to run an
arbitrary logic when a certain thread is terminated.

Modifications:

- Add ThreadDeathWatcher, which spawns a low-priority daemon thread
  that watches a list of threads periodically (every second) and
  invokes the specified tasks when the associated threads are not alive
  anymore
  - Start-stop logic based on CAS operation proposed by @tea-dragon
- Add debug-level log messages to see if ThreadDeathWatcher works

Result:

- Fixes #2519 because we don't use GlobalEventExecutor anymore
- Cleaner code

b0ddfb9b65 [#2525] Use VoidChannelPromise in MessageToMessageEncoder when possible
Motivation:
At the moment MessageToMessageEncoder uses ctx.write(msg) when have more then one message was produced. This may produce more GC pressure then necessary as when the original ChannelPromise is a VoidChannelPromise we can safely also use one when write messages.

Modifications:
Use VoidChannelPromise when the original ChannelPromise was of this type

Result:
Less object creation and GC pressure

d0f3bfd4cc [#2523] Fix infinite-loop when remove attribute and create the same attribute again
Motivation:
The current DefaultAttributeMap cause an infinite-loop when the user removes an attribute and create the same attribute again. This regression was introduced by c3bd7a8ff1.

Modification:
Correctly break out loop

Result:
No infinite-loop anymore.

c255f38647 Correction on StringBuilder default init size
Motivation:
The default StringBuilder size is too small (data.length + 4) while it will be 2*data.length (byte to Hex) + 5 "-" char (since 5 peaces appended).

Modification:
Changing initial size to the correct one

Result:
Allocation of the correct final size from the beginning for this StringBuilder.

ea3dac0753 Do not use a pseudo random for tree traversal
Motivation:

If we make allocateRun/SubpageSimple() always try the left node first and make allocateRun/Subpage() always tries the right node first,  it is more likely that allocateRun/Subpage() will find a node with ST_UNUSED sooner.

Modifications:

- Make allocateRunSimple() and allocateSubpageSimple() always try the left node first.
- Make allocateRun() and allocateSubpage() always try the right node first.
- Remove randome

Result:

We get the same performance without using random numbers.

e5ed69241b Optimize PooledByteBufAllocator
Motivation:

We still have a room for improvement in PoolChunk.allocateRun() and
Subpage.allocate().

Modifications:

- Unroll the recursion in PoolChunk.allocateRun()
- Subpage.allocate() makes use of the 'nextAvail' value set by previous
  free().

Result:

- PoolChunk.allocateRun() optimization yields 10%+ improvements in
  allocation throughput for non-subpage allocations.
- Subpage.allocate() optimization makes the subpage allocations for
  tiny buffers as fast as non-tiny buffers even when the pageSize is
  huge (e.g. 1048576) because it doesn't need to perform a linear search
  in most cases.

0cc264b76b More realistic ByteBuf allocation benchmark
Motivation:

Allocating a single buffer and releasing it repetitively for a benchmark will not involve the realistic execution path of the allocators.

Modifications:

Keep the last 8192 allocations and release them randomly.

Result:

We are now getting the result close to what we got with caliper.

8df9dd7dda Work around the system configuration issue that causes NioSocketChannelTest to fail
Motivation:

On some ill-configured systems, InetAddress.getLocalHost() fails.  NioSocketChannelTest calls java.net.Socket.connect() and it internally invoked InetAddress.getLocalHost(), which causes the test failures in NioSocketChannelTes on such an ill-configured system.

Modifications:

Use NetUtil.LOCALHOST explicitly.

Result:

NioSocketChannelTest should not fail anymore.

9961cae7cf Use a forked exec-maven-plugin instead of maven-antrun-plugin
Motivation:

maven-antrun-plugin does not redirect stdin, and thus it's impossible to
run interactive examples such as securechat-client and telnet-client.
org.codehaus.mojo:exec-maven-plugin redirects stdin, but it buffers
stdout and stderr, and thus an application output is not flushed timely.

Modifications:

Deploy a forked version of exec-maven-plugin which flushes output
buffers in a timely manner.

Result:

Interactive examples work.  Launches faster than maven-antrun-plugin.

223efc5f99 Clean up the examples
Motivation:

The examples have not been updated since long time ago, showing various
issues fixed in this commit.

Modifications:

- Overall simplification to reduce LoC
  - Use system properties to get options instead of parsing args.
  - Minimize option validation
  - Just use System.out/err instead of Logger
  - Do not pass config as parameters - just access it directly
  - Move the main logic to main(String[]) instead of creating a new
    instance meaninglessly
    - Update netty-build-21 to make checkstyle not complain
  - Remove 'throws Exception' clause if possible
- Line wrap at 120 (previously at 80)
- Add an option to enable SSL for most examples
- Use ChannelFuture.sync() instead of await()
- Use System.out for the actual result. Use System.err otherwise.
- Delete examples that are not very useful:
  - applet
  - websocket/html5
  - websocketx/sslserver
  - localecho/multithreaded
- Add run-example.sh which simplifies launching an example from command
  line
- Rewrite FileServer example

Result:

Shorter and simpler examples.  A user can focus more on what it actually
does than miscellaneous stuff.  A user can launch an example very
easily.

c7825f63c0 Fix a bug in DefaultPromise.notifyLateListener() where the listener is not notified
Motivation:

When (listeners == null && lateListeners == null) and (stackDepth >= MAX_LISTENER_STACK_DEPTH), the listener is not notified at all. The discard client does not work.

Modification:

Make sure to submit the notification task.

Result:

The discard client works again and all listeners are notified.

60a83fc6ac Fix packagine issues in all-in-one JAR
Motivation:

- dependencyVersionsDir property is not resolved during the build
  process. The build doesn't fail because of this, but it creates an
  ugly directory.
- All-in-one JAR contains libnetty-tcnative.so, which is not part of the
  all-in-one JAR.

Modifications:

- Fix an incorrect property name
  (dependencyVersionDir -> dependencyVersionsDir)
- Exclude libnetty-tcnative.so
- Remove unnecessary includes in source expanding configuration

Result:

- Cleaner pom.xml
- We do not ship libnetty-tcnative.so in all-in-one JAR anymore, which
  is correct, because strictly speaking the native library belongs to
  org.apache.tomcat.jni package.

37931306d5 Use maven-antrun-plugin instead of exec-maven-plugin
Motivation:

output from the examples invisible to users

Modification:

Result:

A user sees the output from the examples immediately.

5ce410c69e Future compatibility with TLS ALPN
Motivation:

According to TLS ALPN draft-05, a client sends the list of the supported
protocols and a server responds with the selected protocol, which is
different from NPN.  Therefore, ApplicationProtocolSelector won't work
with ALPN

Modifications:

- Use Iterable<String> to list the supported protocols on the client
  side, rather than using ApplicationProtocolSelector
- Remove ApplicationProtocolSelector

Result:

Future compatibility with TLS ALPN

861ed1e7ad Add unified NextProtoNego extension support to SslContext
Motivation:

- OpenSslEngine and JDK SSLEngine (+ Jetty NPN) have different APIs to
  support NextProtoNego extension.
  - It is impossible to configure NPN with SslContext when the provider
    type is JDK.

Modification:

- Implement NextProtoNego extension by overriding the behavior of
  SSLSession.getProtocol() for both OpenSSLEngine and JDK SSLEngine.
  - SSLEngine.getProtocol() returns a string delimited by a colon (':')
    where the first component is the transport protosol (e.g. TLSv1.2)
    and the second component is the name of the application protocol
- Remove the direct reference of Jetty NPN classes from the examples
- Add SslContext.newApplicationProtocolSelector

Result:

- A user can now use both JDK SSLEngine and OpenSslEngine for NPN-based
  protocols such as HTTP2 and SPDY

4436870b28 Clean up the execution mechanism of examples
Motivation:

- There's no way to pass an argument to an example.
- Assigning a Maven profile for each example is an overkill.
  It makes the pom.xml crowded.

Modifications:

- Remove example profiles from example/pom.xml
- Keep the list of examples in run-example.sh
- run-example.sh passes all options to exec-maven-plugin.
  For example, we can now do this:

    ./run-example.sh -Dssl -Dport=443 http-server

Result:

- It's much easier to add a new example and provide an easy way to
  launch it.
- We can still pass an arbitrary argument to the example being launched.
  (I'll update all examples to make them get their options from system
  properties rather than from args[].

c77375cf54 Clean up example execution
Motivation:

- example/pom.xml has quite a bit of duplication.
- We expect that we depend on npn-boot in more than one module in the
  near future. (e.g. handler, codec-http, and codec-http2)

Modification:

- Deduplicate the profiles in example/pom.xml
- Move the build configuration related with npn-boot to the parent pom.
- Add run-example.sh that helps a user launch an example easily

Result:

- Cleaner build files
- Easier to add a new example
- Easier to launch an example
- Easier to run the tests that relies on npn-boot in the future

4882377c27 Work around the JVM crash that occurs when cipher suite uses GCM
Motivation:

For an unknown reason, JVM of JDK8 crashes intermittently when
SslHandler feeds a direct buffer to SSLEngine.unwrap() *and* the current
cipher suite has GCM (Galois/Counter Mode) enabled.

Modifications:

cipher suite is using GCM.

ae61b12b9e Reduce memory usage of SslHandler when OpenSslEngine is in use
Motivation:

JDK's SSLEngine.wrap() requires the output buffer to be always as large as MAX_ENCRYPTED_PACKET_LENGTH even if the input buffer contains small number of bytes.  Our OpenSslEngine implementation does not have such wasteful behaviot.

Modifications:

If the current SSLEngine is OpenSslEngine, allocate as much as only needed.

Result:

Less peak memory usage.

9125060752 Optimize SslHandler in an OpenSslEngine-friendly way
Motivation:

Previous fix for the OpenSslEngine compatibility issue (#2216 and
18b0e95659) was to feed SSL records one by
one to OpenSslEngine.unwrap().  It is not optimal because it will result
in more JNI calls.

Modifications:

- Do not feed SSL records one by one.
- Feed as many records as possible up to MAX_ENCRYPTED_PACKET_LENGTH
- Deduplicate MAX_ENCRYPTED_PACKET_LENGTH definitions

Result:

- No allocation of intemediary arrays
- Reduced number of calls to SSLEngine and thus its underlying JNI calls
- A tad bit increase in throughput, probably reverting the tiny drop
  caused by 18b0e95659
