791c38befe [#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

2fa79b2d5d [#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

844362a947 User-definable thread model via ChannelHandlerInvoker
Motivation:

While the default thread model provided by Netty is reasonable enough for most applications, some users might have a special requirement for the thread model.  Here are a few examples:

- A user might want to invoke handlers from the caller thread directly, assuming that his or her application is completely asynchronous and does not make any invocation from non-I/O thread.  In this case, the default invoker implementation will only add the overhead of checking if the current thread is an I/O thread or not.
- A user might want to invoke handlers from different threads depending on the type of events flexibly.

Modifications:

- Backport 132af3a485 which is a fix for #1912
  - Add a new interface called 'ChannelHandlerInvoker' that performs the invocation of event handler methods.
  - Add pipeline manipulation methods that accept ChannelHandlerInvoker
- The differences from the original commit:
  - Separated the irrelevant changes out
  - Channel.eventLoop is null until the registration is complete in this branch, so Channel.Unsafe.invoker() doesn't work before registration.
  - Deregistration is not gone in this branch, so the methods related with deregistration were added to ChannelHandlerInvoker

32ccdcdb18 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.

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.

1a72bd09d5 Fix 'incompatible event loop' regression
Motivation:

Previous commit (2de65e25e9) introduced a regression that makes the epoll testsuite fail with an 'incompatible event loop' error.

Modifications:

Use the correct event loop type.

Result:

Build doesn't fail anymore.

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.

218bb8b034 Replace usage of UnknownHostException with UnresolveableAddressException. Part of [#2262]
Motivation:
We better use UnresolveableAddressException as NIO does the same.

Modifications:
Replace usage of UnknownHostException with UnresolveableAddressException

Result:
epoll transport and nio transport behave the same way

4f5f4cdc9d [#2262] Fix NPE triggered by unresolveable InetSocketAddress in epoll transport
Motivation:
At the moment when an unresolvable InetSocketAddress is passed into the epoll transport a NPE is thrown

Modifications:
Add check in place which will throw an UnknownHostException if an InetSocketAddress could not been resolved.

Result:
Proper handling of unresolvable InetSocketAddresses

47fab2bfe8 Directly use memory addresses for gathering writes to reduce gc pressure. Part of [#2239]
This also does factor out some logic of ChannelOutboundBuffer. Mainly we not need nioBuffers() for many
transports and also not need to copy from heap to direct buffer. So this functionality was moved to
NioSocketChannelOutboundBuffer. Also introduce a EpollChannelOutboundBuffer which makes use of
memory addresses for all the writes to reduce GC pressure

9330172f80 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
