a74c6b4692 Generate the default JAR to make oss.sonatype.org happy
Motivation:

oss.sonatype.org refuses to promote an artifact if it doesn't have the
default JAR (the JAR without classifier.)

Modifications:

- Generate both the default JAR and the native JAR to make
  oss.sonatype.org happy
- Rename the profile 'release' to 'restricted-release' which reflects
  what it really does better
- Remove the redundant <quickbuild>true</quickbuild> in all/pom.xml
  We specify the profile 'full' that triggers that property already
  in maven-release-plugin configuration.

Result:

oss.sonatype.org is happy.  Simpler pom.xml

568295d6c0 Simplify native library resolution using os-maven-plugin
Motivation:

So far, we used a very simple platform string such as linux64 and
linux32.  However, this is far from perfection because it does not
include anything about the CPU architecture.

Also, the current build tries to put multiple versions of .so files into
a single JAR.  This doesn't work very well when we have to ship for many
different platforms.  Think about shipping .so/.dynlib files for both
Linux and Mac OS X.

Modification:

- Use os-maven-plugin as an extension to determine the current OS and
  CPU architecture reliable at build time
- Use Maven classifier instead of trying to put all shared libraries
  into a single JAR
- NativeLibraryLoader does not guess the OS and bit mode anymore and it
  always looks for the same location regardless of platform, because the
  Maven classifier does the job instead.

Result:

Better scalable native library deployment and retrieval

ee55d34cfe [#2414] Fix IllegalStateException when try to configure AbstractEpollChannel once it is deregistered
Motivation:
AbstractEpollChannel.clearEpollIn() throws an IllegalStateException if a user tries to change the autoRead configuration for the Channel and the Channel is not registered on an EventLoop yet. This makes it for example impossible to set AUTO_READ to false via the ServerBootstrap as the configuration is modifed before the Channel is registered.

Modification:
Check if the Channel is registered and if not just modify the flags directly so they are respected once the Channel is registered

Result:
It is possible now to configure AUTO_READ via the ServerBootstrap

12ac35cd57 [#2414] Fix RuntimeException during modify events via EpollEventLoop
Motivation:
We are currently try to modify the events via EpollEventLoop even when the channel was closed before and so the fd was set to -1. This fails with a RuntimeException in this case.

Modification:
Always check if the Channel is still open before try to modify the events.

Result:
No more RuntimeException because of a not open channel

302d116728 Use correct generics for TCP_KEEPIDLE, TCP_KEEPINTVL and TCP_KEEPCNT in EpollChannelOption. Part of [#2396]
Motivation:
Currently the generics used for TCP_KEEPIDLE, TCP_KEEPINTVL and TCP_KEEPCNT are incorrect.

Modifications:
Use Integer as type

Result:
User can use TCP_KEEPIDLE, TCP_KEEPINTVL and TCP_KEEPCNT as expected

886829d7e0 Fix buffer leak in EpollDatagramChannel
Motivation:
EpollDatagramChannel produced buffer leaks when tried to read from the channel and nothing was ready to be read.

Modifications:
Correctly release buffer if nothing was read

Motivation:
Allow to set TCP_KEEPIDLE, TCP_KEEPINTVL and TCP_KEEPCNT in native transport to offer the user with more flexibility.

Modifications:
Expose methods to set these options and write the JNI implementation.

Result:
User can now use TCP_KEEPIDLE, TCP_KEEPINTVL and TCP_KEEPCNT.

f5d4e6b10e [#2405] Add support for SO_REUSEPORT to EpollDatagramChannel
Motivation:
With SO_REUSEPORT it is possible to bind multiple sockets to the same port and so handle the processing of packets via multiple threads. This allows to handle DatagramPackets with more then one thread on the same port and so gives better performance.

Modifications:
Expose EpollDatagramChannelConfig.setReusePort(..) and isReusePort()

Result:
Allow to bind multiple times to the same local address and so archive better performance.

c2dc993c42 [#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.

72a077b6c7 [#2377] Implement epoll based DatagramChannel
Motivation:
There is currently no epoll based DatagramChannel. We should add one to make the set of provided channels complete and also to be able to offer better performance compared to the NioDatagramChannel once SO_REUSEPORT is implemented.

Modifications:
Add implementation of DatagramChannel which uses epoll. This implementation does currently not support multicast yet which will me implemented later on. As most users will not use multicast anyway I think it is fair to just add the EpollDatagramChannel without the support for now. We shipped NioDatagramChannel without support earlier too ...

Result:
Be able to use EpollDatagramChannel for max. performance on linux

02c3e71012 [#2376] Add support for SO_REUSEPORT in native transport
Motivation:
In linux kernel 3.9 a new featured named SO_REUSEPORT was introduced which allows to have multiple sockets bind to the same port and so handle the accept() of new connections with multiple threads. This can greatly improve the performance when you not to accept a lot of connections.

Modifications:
Implement SO_REUSEPORT via JNI

Result:
Be able to use the SO_REUSEPORT feature when using the EpollServerSocketChannel

9cf92b3999 [#2371] Fix data corruption caused by EpollSocketChannel when writing
Motivation:
We sometimes see data corruption when writing to the EpollSocketChannel.

Modifications:
The problem was caused as we mixed writing via memory address and via ByteBuffer. This not works out pretty well because of how the position of the buffer is updated etc. To fix the problem we only write via ByteBuffer (this is true for normal and gathering writes). Before normal writes may write via the memory address and gathering writes always used the ByteBuffer.

Result:
Fix data-corruption which could happen on partial writes

012166803a [#2353] Use a privileged block to get ClassLoader and System property if needed
Motivation:
When using System.getProperty(...) and various methods to get a ClassLoader it will fail when a SecurityManager is in place.

Modifications:
Use a priveled block if needed. This work is based in the PR #2353 done by @anilsaldhana .

Result:

a4c80211ea [#2359] EpollSocketChannel.remoteAddress0() is always null on accepted EpollSocketChannels
Motivation:
EpollSocketChannel.remoteAddress0() is always null on accepted EpollSocketChannels as we not set it excplicit.

Modifications:
Correctly retrieve the local and remote address when accept new channel and store it

Result:
EpollSocketchannel.remoteAddress0() and EpollSocketChannel.localAddress0() return correct addresses

9d695e03db [#2361] Native.epollCreate(...) fails on systems using a kernel < 2.6.27 / glibc < 2.9
Motivation:
Native.epollCreate(...) fails on systems using a kernel < 2.6.27 / glibc < 2.9 because it uses epoll_create1(...) without checking if it is present

Modifications:
Check if epoll_create1(...) exists abd if not fall back to use epoll_create(...)

Result:
Works even on systems with kernel < 2.6.27 / glibc < 2.9

76d091a884 Make sure the local / remote InetSocketAddres can be obtained. Part of [#2262]
Motivation:
Make sure the remote/local InetSocketAddress can be obtained correctly

Modifications:
Set the remote/local InetSocketAddress after a bind/connect operation was performed

Result:
It is possible to still access the informations even after the fd became invalid. This mirror the behaviour of NIO.

5acb8759e4 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.

eda702b6ab 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.

1edca5f8d9 Introduce a native transport for linux using epoll ET
This transport use JNI (C) to directly make use of epoll in Edge-Triggered mode for maximal performance on Linux. Beside this it also support using TCP_CORK and produce less GC then the NIO transport using JDK NIO.
It only builds on linux and skip the build if linux is not used. The transport produce a jar which contains all needed .so files for 32bit and 64 bit. The user only need to include the jar as dependency as usually
to make use of it and use the correct classes.

This includes also some cleanup of @trustin
