Netty 3.2.0.ALPHA1 released: New Journey to the Next Level

2009-11-16T05:39:55Z

Hi folks,

Netty 3.2.0.ALPHA1, the first milestone in the 3.2 branch, has been released.

The Netty project is an effort to provide an asynchronous,
event-driven network application framework and tools for rapid
development of maintainable, high-performance, high-scalability
protocol servers and clients.

In other words, Netty is a NIO client server framework that enables
quick and easy development of network applications such as protocol
servers and clients. It simplifies and streamlines network programming
such as TCP and UDP socket servers

Please visit our web site to download it. Your feed back is more than
appreciated - please visit the discussion forum and leave some
comments and questions:

* http://www.jboss.org/netty/

Compression Handlers
====================
The ability to compress and decompress a connection transparently was
one of the early feature requests in Netty development. The
compression handlers introduced in this release add complete support
for both GZIP and ZLIB compression encoding, which is not found in any
other NIO application frameworks. For more information, please look
at the org.jboss.netty.handler.codec.compression package.

On top of the new compression handlers, HTTP content compression /
decompression support has been added, too. Please take a look at the
HTTP snoop client / server example for more information.

New Testimonial
===============
Dave Siracusa from Perfware LLC sent a nice testimonial for Netty
recently. You will find it very interesting; he succeeded to write an
HTTP server which is capable of processing 15,000 messages per second
on top of Netty. Check his recommendation and other testimonials
here: http://www.jboss.org/netty/testimonials.html

Upcoming Releases
=================
Although we did not add many new features in this first alpha, we have
bunch of new features planned, and they are all public in our issue
tracker and mailing list. Please feel free to join the discussion and
keep us updated with any ideas for new features, bugs, design issues,
API usability feed back, and questions - your idea is the future of
Netty!

Netty 3.1.0.CR1 released: Large Data Streaming, HTTP Performance, and Javadoc

2009-06-22T19:20:39Z

Hi community,

Netty 3.1.0.CR1, the first release candidate of 3.1 branch, has been
released.

The Netty project is an effort to provide an asynchronous, event-driven
network application framework and tools for rapid development of
maintainable, high-performance, high-scalability protocol servers and
clients.

In other words, Netty is a NIO client server framework that enables
quick and easy development of network applications such as protocol
servers and clients. It simplifies and streamlines network programming
such as TCP and UDP socket servers.

Success Story - 100,000 Concurrent HTTP Connections
===================================================
Amir Aslihefendic was able to write a Comet server in just 1 day with
Netty, after evaluating many alternatives. His server is now serving
100,000 concurrent HTTP connections at Plurk.com. For more stories,
read his post: http://tinyurl.com/kpnjne

Do you have a story to share with us about Netty? Then please do not
hesitate to contact us - such a story will make my day!

Complete Javadoc
================
As promised, this release includes full Javadoc for all public and
protected methods. Any new features added in 3.1 should be easier to
use now. I believe the documentation can be even better with your
ongoing feed back. Please feel free to contact us if the documentation
does not tell you what you want to know about Netty or if it could be
better organized.

Large Data Streaming
====================
Writing a large file or stream in a non-blocking asynchronous framework
requires somewhat complex state management because asynchronous writes
can lead to buffer overrun and OutOfMemoryError. Therefore, data
streaming was a highly demanded feature by the community. This release
introduces ChunkedWriteHandler which makes large media streaming easier
than ever. HTTP static file server has been added as an example:
http://tinyurl.com/n95or2

HTTP Performance Improvements
=============================
The performance of HTTP decoder has been improved even further. It is
expected for most HTTP applications to experience about 10% performance
boost, although your mileage may vary.

Proxy Server Example
====================
One of the most frequently asked questions is 'how do I write a proxy
server with Netty?' Because proxy server mixes the server-side and
client-side terms for explanation, there is higher chance of confusion
during the conversation. So, I wrote a working proxy example. Enjoy:
http://tinyurl.com/qq7ghu

Upcoming Releases
=================
The next release will be 3.1.0.GA with higher stability. Please keep us
updated with any bugs, design issues, API usability feed back, and
questions.

Netty 3.1.0.BETA3 released: Performance and Little Endian

2009-05-25T22:38:29Z

Hi folks,

Netty 3.1.0.BETA3, the third beta release of 3.1 branch, has been released.

The Netty project is an effort to provide an asynchronous, event-driven network application framework and tools for rapid development of maintainable, high-performance, high-scalability protocol servers and clients.

In other words, Netty is a NIO client server framework that enables quick and easy development of network applications such as protocol servers and clients. It simplifies and streamlines network programming such as TCP and UDP socket servers.

Alternatively, please follow us at Twitter and send a message:

Improved Performance
====================
Thanks to Wade Poziombka's help, the NIO socket transport became even faster than ever. Thanks Wade!

ConnectionlessBootstrap
=======================
Datagram support has been added in 3.1.0.BETA1, but it didn't have a proper Bootstrap implementation. This release adds the ConnectionlessBootstrap which extends Bootstrap to support Old IO based UDP transport and other planned connectionless transports. The 'Quote of the Moment' example has been updated following this change.

Little Endian Support
=====================
Although most binary protocol uses big endian, some proprietary protocols which were developed on x86 or x64 architecture use little endian. Preliminary support for little endian was added in 3.1.0.ALPHA3, but it didn't work very well for a certain case. This release fixes that particular case. Now it seems to work flawlessly.

In case you wonder what endianness is, please refer to the Wikipedia:

* http://en.wikipedia.org/wiki/Endianness

Building on Windows
===================
maven-jdocbook-plugin was misconfigured to lead 'connection timed out' during docbook generation, hence the full build fails. I recently had a chance to run a build on Windows by myself and was able to fix the build failure.

Upcoming Releases
=================
The next release will be 3.1.0.CR1 (Candidate Release) with complete Javadoc. Please keep us updated with any bugs, design issues, API usability feed back, and questions.

Netty 3.1.0.BETA2 released - A New Chapter in the User Guide and Dead Lock Auto-detection

2009-04-18T09:05:02Z

Hi folks,

Netty 3.1.0.BETA2, the second beta release of 3.1 branch, has been released.

The Netty project is an effort to provide an asynchronous,
event-driven network application framework and tools for rapid
development of maintainable, high-performance, high-scalability
protocol servers and clients.

A New Chapter in the User Guide
===============================
If you were following us at Twitter ( http://twitter.com/netty_project
), you might already have noticed that we updated the user guide to
reflect the feed back from the community. Please check it out; it
worths a read! - http://tinyurl.com/b2snx4

Dead Lock Auto-detection
========================
It is a common mistake for a Netty beginner to call
ChannelFuture.await*() method when a ChannelHandler is running in an
I/O worker thread. The ChannelFuture implementation now throws an
IllegalStateException if a user called ChannelFuture.await*() from an
I/O worker thread. Just in case you didn't know about this, please
read the updated Javadoc of ChannelFuture: http://tinyurl.com/dyooey

SSL Bug Fixes
=============
A couple issues related with SslHandler were found by community
members, and they were all fixed thanks to the detailed bug report
from them. I'd like to say thank you again to Virat Gohil, Bryan
Wagner, and Huican Ping, in no particular order.

Upcoming Releases
=================
If there's no noticeable bugs and I have done enough documentation and
testing, the next release will be 3.1.0.CR1 (Candidate Release).
Otherwise, it will be 3.1.0.BETA3. Please keep us updated with any
bugs, design issues, API usability feed back, and questions.

Re: Netty 3.1.0.BETA1 released - HTTP Improvements & UDP transport

2009-03-16T02:27:30Z

Forgot to mention another major feature:

Per-ChannelHandler Attachment
=============================
ChannelHandlerContext.get/setAttachment() method has been added. Now
that every ChannelHandler in a pipeline has its own storage per
Channel, it is much easier to write a handler whose
ChannelPipelineCoverage is 'all', which needs to maintain both
per-channel and global states.

Thanks!

Netty 3.1.0.BETA1 released - HTTP Improvements & UDP transport

2009-03-16T02:00:55Z

Hi folks,

Netty 3.1.0.BETA1, the first beta release of 3.1 branch, has been
released. The Netty project is an effort to provide an asynchronous,
event-driven network application framework and tools for rapid
development of maintainable, high-performance, high-scalability
protocol servers and clients. In other words, Netty is a NIO client
server framework that enables quick and easy development of network
applications such as protocol servers and clients. It simplifies and

discussion forum and leave some comments and questions:

* http://www.jboss.org/netty/community.html

HTTP Improvements
=================
There were a number of improvements in the HTTP codec. The most
important change is the emulation of chunked encoding. Previously, a
large HTTP message was loaded into a large memory buffer taking up as
much space as the length of the content and headers. It will simply
fail when your HTTP server is under heavy load. To address this
issue, HttpMessageDecoder now splits a large request or response into
a multiple chunks making it looks like a chunked message.

The advantage of this change is that you have much more control over
OutOfMemoryError when you write a media / file server on top of Netty.
The disadvantage is that your handler needs to understand HttpChunk
message type, too. To learn how to deal with HttpChunks, please take
a look at the revised HTTP client / server example:

* http://tinyurl.com/5w3fpb - see HttpRequestHandler and HttpResponseHandler

Alternatively, you can append HttpChunkAggregator to the pipeline to
let Netty merge HttpChunks just like the previous releases. This
handler is useful when you prefer simplicity over memory efficiency.
For more information, please check this forum thread:
http://tinyurl.com/cqb7hy

Besides the chunk emulation, you can now limit the length of headers
to avoid unnecessary memory consumption due to malicious or malformed
HTTP message. HTTP cookie encoder and decoder have been improved
vastly, too; cookie version 0, 1, and 2 are all supported.

UDP Transport
=============
UDP transport, the very long-awaited feature, has been implemented.
It's not NIO based but old I/O based. It should perform fine because
most UDP applications don't open many sockets because one socket is
supposed to serve datagrams from different remote addresses. Plus, it
does support multicast. I wrote the 'Quote of the Moment' (QOTM)
example that shows the basic usage of the UDP transport. As a bonus,
you will enjoy some inspiring quotes from Gandhi. :)

CompatibleObjectDecoder Deprecated
==================================
I had to deprecate CompatibleObjectDecoder due to a known yet
incurable critical issue. If you were using it, please switch to
ObjectEncoder, ObjectDecoder, ObjectEncoderOutputStream, and
ObjectDecoderInputStream. For more information, please check the
related JIRA issue: https://jira.jboss.org/jira/browse/NETTY-136

If you have a good idea to make it work correctly, please let me know.
Then we might be able to un-deprecate it.

Upcoming Releases
=================
If there's no noticeable bugs and I have done enough documentation and
testing, the next release will be 3.1.0.CR1 (Candidate Release).
Otherwise, it will be 3.1.0.BETA2. Please keep us updated with any
bugs, design issues, API usability feed back, and questions.

Netty 3.1.0.ALPHA4 released - Chunked encoding, Idle state detection, New transports, and more.

2009-03-02T04:07:38Z

Hi folks,

Netty 3.1.0.ALPHA4, the last alpha release of 3.1 branch, has been
released. Please visit our web site to download it:

* http://www.jboss.org/netty/

As always, your feed back is more than appreciated. Please visit the
discussion forum and leave some comments and questions:

* http://www.jboss.org/netty/community.html

IdleStateHandler and Read/WriteTimeoutHandler
=============================================
We often need to take some action when a remote peer doesn't send any
data for a while or when we don't have anything to send for a while.
For example, the action taken could be either sending a 'ping' message
or closing a connection. To implement such a behavior in Netty,
previously you had to rely on java.util.Timer or
java.util.concurrent.ScheduledThreadPoolExecutor. As of this release,
the org.jboss.netty.handler.timeout package provides a one-stop
solution for this particular use case.

Unlike other frameworks that provide similar features, we have wrote
the internal timer implementation from scratch very carefully. The
resulting timer implementation is highly efficient and optimized for
handling the timeouts of a large number of connections. Also, this is
completely optional, so there is zero overhead unless you add the
handlers to a pipeline.

Chunked Encoding Support for HTTP
=================================
The most demanded feature since Netty introduced its HTTP layer was
the support for chunked encoding, and it is now part of this release.
The HTTP example (in org.jboss.netty.example.http) has been revised to
demonstrate how to deal with HTTP chunked encoding along with an
ordinary transfer coding. Now you can build a high capacity HTTP
streaming server more rapidly than ever on top of Netty.

HTTP Tunneling Transport
=========================
HTTP Tunneling Transport (in org.jboss.netty.channel.socket.http) is a
socket transport which allows any existing socket applications to be
proxied over HTTP. This transport is particularly useful when you
need to bypass a firewall without modifying an existing server
application. To illustrate how this works, it looks like the
following:

HttpTunnelingClientSocketChannel
|
\|/
HTTP-friendly Firewall
|
\|/
Servlet Container (e.g. Tomcat, Jetty)
|
\|/
HttpTunnelingServlet
|
\|/
Your Server Application

You might think we could also provide a standalone HTTP server which
is dedicated to this configuration. Yes, that is a good idea, and any
contribution is appreciated in advance. ;)

Local Transport
===============
The local transport, as known as in-VM transport, is another long
awaited addition to 3.1. Using the local transport, you can let your
Netty applications in the same virtual machine talk to each other
using your favorite Netty channel API without opening any actual
sockets. It should be useful for unit testing, too.

XNIO Transport
==============
JBoss XNIO is a simplified low-level I/O layer, written by David M.
Lloyd, which can be used anywhere you are using NIO today. It
supports TCP, UDP, and Multicast out of the box. Therefore, we could
safely say that Netty now supports UDP via XNIO Transport.

WriteCompletionEvent
====================
So far, there was no way to figure out how many bytes (or messages)
were successfuly written for a channel. Now, a WriteCompletionEvent
is triggered for every successful writes so that you can get the
amount of written data immediately. With this event, you can get
meaningful statistics about a channel such as when was the last time
there was outgoing traffic in a channel.

LoggingHandler
==============
By popular demand, a LoggingHandler has been added purely for a
debugging purpose. It logs all upstream and downstream events in
debug level. Myself finds it very useful when I need to track down
what is going on inside a pipeline. Also, it's a good example that
shows how to write a ChannelHandler: http://tinyurl.com/b5ogmk

Channel ID is not UUID anymore but an integer
=============================================
The return type of Channel.getId() has been changed from
java.util.UUID to java.lang.Integer. Unfortunately, it is a backward
incompatible change which might require some changes in your code,
although the changes should be trivial in most cases. The upside of
this change is that it will take much less memory and the string
representation of the channel ID will be much more concise. I hope
you like the change. Apologies!

Upcoming Releases
=================
3.1.0.ALPHA4 is the last alpha version, and we believe that we have
resolved most design issues raised since 3.0. 3.1.0.BETA1 will be
released with the fixes and minor improvements for all reported
problems from bugs to fundamental design issues. Also, documentation
will be on its way. Please let us know what you'd like to see in the
upcoming releases.

Netty 3.1.0.ALPHA3 released: integration, integration, and integration

2009-01-13T05:23:47Z

Hi folks,

It's been a long time! Netty 3.1.0.ALPHA3, the third milestone of the
another major feature release iteration, has been released. Please
visit our web site to download it:

* http://www.jboss.org/netty/

As always, your feed back is more than appreciated. Please visit the
discussion forum and leave some comments and questions:

* http://www.jboss.org/netty/community.html

Integration with Google Protocol Buffers
========================================
What are Google Protocol Buffers?

"Google Protocol Buffers are a flexible, efficient, automated
mechanism for serializing structured data - think XML, but smaller,
faster, and simpler. You define how you want your data to be
structured once, then you can use special generated source code to
easily write and read your structured data to and from a variety of
data streams and using a variety of languages. You can even update
your data structure without breaking deployed programs that are
compiled against the "old" format," cited from 'Google Protocol
Buffers Developer Guide' - http://tinyurl.com/68e2x4

Doesn't it sound like an ideal solution for the rapid implementation
of a highly efficient yet evolvable binary protocol? Indeed. With
the ProtobufEncoder and ProtobufDecoder (in
org.jboss.netty.handler.codec.protobuf), you can adapt the message
classes generated by Google Protocol Buffers compiler (protoc) into
Netty codec. Please take a look around the new 'LocalTime' example
that shows how easily you can create a high-performing binary protocol
client and server:

* LocalTimeProtocol.proto - http://tinyurl.com/7melgo
* LocalTimeServer - http://tinyurl.com/9y8kfj
* LocalTimeClient - http://tinyurl.com/9jvxa3

Integration with IoC/DI technologies
====================================
Creating an instance of ChannelFactory was not very easy when you want
to create them for your favorite IoC container. In many cases, you
want the ChannelFactory created and injected by the IoC container to
be destroyed properly, too. This release adds the integration with
four leading IoC/DI technologies:

* JBoss Microcontainer: http://www.jboss.org/jbossmc/
* ChannelFactories are automatically installed on deployment.
* Related resources are automatically acquired and released.
* Internal log messages are redirected to JBoss Logging SPI.

* OSGi framework: http://www.osgi.org/
* ChannelFactories are automatically registered as services on startup.
* Related resources are automatically acquired and released.
* Internal log messages are redirected to OSGi LogService.

* Google Guice: http://code.google.com/p/google-guice/
* A convenience module (NettyModule)
* Various providers
* An annotation for precise resource (Executor) injection

* Spring framework: http://www.springframework.org/
* Import classpath:/org/jboss/netty/container/spring/beans.xml
* Source: http://tinyurl.com/7okf33
* ConfigurableApplicationContext.close() will release all resources.

Please note that the name of each registered / installed /
instantiated ChannelFactory is identical with its fully qualified
class name. For example, you can look up
NioServerSocketChannelFactory with the service name
'org.netty.jboss.channel.socket.nio.NioServerSocketChannelFactory' in
OSGi. Alternatively, you can specify
'org.netty.jboss.channel.socket.ServerSocketChannelFactory' so that
Netty can choose the proper ServerSocketChannelFactory implementation
(it's NioServerSocketChannelFactory for now.)

Also, please let me know if you have some nice idea to integrate Netty
better into the container technologies mentioned above, I'd be pleased
to listen to you.

Codec improvements
==================
Various options have been added to existing codec classes. For
example, you can tell DelimiterBasedFrameDecoder to include the
delimiter in the frame now. Also, simple yet useful codec classes
were added for your convenience:

* LengthFieldBasedFrameDecoder - http://tinyurl.com/9rzasc
* decodes a frame by looking in the length field of a message

* LengthFieldPrepender - http://tinyurl.com/852d57
* prepends a binary integer header to the message

* Base64 codec - http://tinyurl.com/97aswz

These are small changes and additions but you will find combining
these constructs will help you decode a proprietary protocol fairly
easily without much coding.

org.jboss.netty.group -> org.jboss.netty.channel.group
======================================================
The classes in the org.jboss.netty.group package, which were
introduced in 3.1.0.ALPHA2 have been moved to the
org.jboss.netty.channel.group package.

Upcoming Releases
=================
All features added in this release will be reviewed continuously
following up your feed back. 3.1.0.ALPHA4 will be the last alpha
version with most noticeable design issues resolved. Please feel free
to browse the road map and let us know what you think about it:

* http://tinyurl.com/5vpxux

Please also note that we are always open to your suggestion and
contribution on any feature which is not listed in the road map yet.

Netty 3.1.0.ALPHA2 released - More bells and whistles

2008-12-03T17:25:07Z

Hi folks,

Netty 3.1.0.ALPHA2, the second milestone of the another major feature
release iteration has been released. Please visit our web site to
download it:

* http://www.jboss.org/netty/

As always, your feed back is more than appreciated. Please visit the
discussion forum and leave some comments and questions:

* http://www.jboss.org/netty/community.html

Reliable and Configurable Write Buffer Overflow Prevention
==========================================================
Netty now ships with high and low water mark based write buffer
overflow prevention mechanism, which is much more robust, high-
performing, and configurable. You can configure the high and low
water mark of the write buffer size via NioSocketChannelConfig.

In other words, you have much lower chance of getting OutOfMemoryError
than before!

If the byte unit size of the write buffer exceeds high water mark,
Channel.isWritable() will return false until the byte unit size of
the write buffer goes down under the low water mark. Also,
'channelInterestChanged' event will be fired to notify the status of the
write buffer.

See here for more information: https://jira.jboss.org/jira/browse/NETTY-71

CodecEmbedder
=============
CodecEmbedder (org.jboss.netty.handler.codec.embedder) has been added
to greatly simplify:

* testing Netty encoders and decoders, and
* calling Netty encoders and decoders without setting up mock objects
by yourself, so that they can be used within other codec to build a
multi-layered protocol or even be used to integrate with a non-Netty
application that needs to interoperate with a Netty application.

For the detailed description and examples, please see the following
page: https://jira.jboss.org/jira/browse/NETTY-87

ChannelGroup
============
ChannelGroup (org.jboss.netty.group) allows you to create a set of
Channels and perform a bulk operations on it.

For example, you could add all open Channels to a ChannelGroup and
close all of them before shutting down the service. This will greatly
simplify the service shut down in combination with the
ChannelFactory.releaseExternalResources(), which has been added in
the previous release.

Also, you can broadcast a message to many sessions in just one call, and
can wait for each write request to be done via ChannelGroupFuture.
ChannelGroupFuture also lets you add ChannelGroupFutureListeners just
like you can add ChannelFutureListener to ChannelFuture, and allows you
to determine if the request was completely successful, partially
successful, completely failed. or partially failed.

ChannelLocal
============
I found some users still miss the attribute map of MINA IoSession, and
ChannelLocal is the alternative solution to meet their needs. Using
ChannelLocal, you can add an attribute to Channels more efficiently from
both performance and memory consumption perspective.

The usage of ChannelLocal is very similar to that of ThreadLocal, which
ChannelLocal was named after:

final ChannelLocal<String> myAttr = new ChannelLocal<String>();
...
String a = myAttr.get(channel);
myAttr.set(channel, "newValue");
myAttr.remove(channel);

Please note that Channel always should be specified unlike ThreadLocal,
because there's no elegent way to figure out what the 'current' Channel
is. (In contrast, ThreadLocal uses Thread.currentThread().) Any idea
to improve the usability of ChannelLocal is appreciated.

Upcoming Releases
=================
All features added in this release will be reviewed continuously
following up your feed back. A couple more alpha versions will be
released with more new features and improvements. Please feel free to
browse the road map and let us know what you think about it:

* http://tinyurl.com/5vpxux

Netty 3.1.0.ALPHA1 released - HTTP and convenient service shutdown

2008-11-26T11:38:35Z

Hi community,

Netty 3.1.0.ALPHA1, the beginning of the another major feature release
iteration has been released. Please visit our web site to download it:

* http://www.jboss.org/netty/

As always, your feed back is more than appreciated. Please visit the
discussion forum and leave some comments and questions:

* http://www.jboss.org/netty/community.html

HTTP Codec
==========
Thanks to Andy Taylor's contribution, this first alpha release ships
with a preliminary implementation of HTTP codec. It's a low level codec
that enables the development of highly customized HTTP clients and
servers. Please take a look at the HTTP client/server example:

* http://tinyurl.com/5w3fpb

You will find a great degree of freedom and little restriction, which
means it's completely up to you to conform to the standard or not. If
there's enough demand, Netty could provide more high-level standard
compliant HTTP component which is similar to what Apache HttpComponents
provides.

I'd like appreciate Andy's effort again to make this possible sooner
than I originally expected. Please let us know if anything is missing
or any improvement in the API is required.

More Convenient Service Shutdown
================================
Many users have been asking how to shut down a service correctly so that
there's no remaining threads. There was an explicitly documented
procedure to shut down a service, but it was somewhat complicated than
it is supposed to be.

In this release, ChannelFactoryResource interface has been added to
simplify the service shut down procedure. All client examples have been
updated to demonstrate this feature. For instance, the FactorialClient
example is much more elegant than before - no more System.exit()!

* http://tinyurl.com/5d7xoa

It still requires you to close all open channels managed by the
ChannelFactory, but it will be dealt with in the next release.

Channel.getCloseFuture()
========================
It is now possible to wait until a channel is closed more conveniently.
You will always be notified with a channelClosed event whan a channel is
closed as Netty does in 3.0, but Channel.getCloseFuture() will give you
more choice on it. It's especially useful when you write a client
application and want to wait until a channel is closed in background:

Channel c = ...;
c.getCloseFuture().awaitUninterruptibly();

Upcoming Releases
=================
All features added in this release will be reviewed continuously
following up your feed back. A couple more alpha versions will be
released with more new features and improvements. Please feel free to
browse the road map and let us know what you think about it:

* http://tinyurl.com/5vpxux

Netty 3.0.0.CR5 released - Performance that rocks!

2008-10-06T21:40:44Z

Hi folks,

Netty 3.0.0.CR5, the fifth release candidate of Netty 3.0.0 has been
released. Please visit our web site to download it:

* http://www.jboss.org/netty/

As always, your feed back is more than appreciated. Please visit the
discussion forum and leave some comments:

* http://www.jboss.org/netty/community.html

The Best Performance Ever
=========================

I have published the performance test report which compares the
performance of 5 open source NIO frameworks including Netty. According to
the test result, Netty 3.0.0.CR5 seems to have achieved a breakthrough in
NIO framework performance. Read here:

* http://www.jboss.org/netty/performance.html

SimpleChannelHandler Just Got More Convenient
=============================================

SimpleChannelHandler now implements ChannelDownstreamHandler along with
ChannelUpstreamHandler. It simplifies the implementation of a downstream
event handler significantly. The user guide has been updated and
simplified thanks to this change.

Bug Fixes
=========

Various bugs were found and fixed during the performance test. Most of
them were race conditions under heavy load.

On the other hand, a bug in object serialization codec was fixed thanks to
the detailed bug report by Frederic. Thanks, Frederic!

Upcoming Releases
=================

Unless a major issue is reported within the next iteration, Netty
3.0.0.CR5 will become a GA release.

Netty 3.0.0.CR4 released - now with a Getting Started Guide!

2008-09-22T06:08:59Z

Hi folks,

Netty 3.0.0.CR4, the fourth release candidate of Netty 3.0.0 has been
released. Please visit our web site to download it:

* http://www.jboss.org/netty/

As always, your feed back is more than appreciated. Please visit the
discussion forum and leave some comments:

* http://www.jboss.org/netty/community.html

The User Guide
==============

The biggest and sole addition in this release is the user guide, which is
distributed in various formats such as HTML and PDF. Although many
chapters in the document is not written yet, it should be enough for a
beginner to write a network application on top of Netty right away.
Please feel free to comment. I know it needs a lot more work and there
are many missing pieces yet. Please check it out now!

* http://tinyurl.com/4375n7

Performance Improvements
========================

Overall startup and shutdown time has been decreased significantly. If
you were starting and stopping a server or a client frequently, you will
experience a lot of speedup.

Also, a slowdown has been fixed, which happens when a user tries to write
a message when the channel is closed already. This issue was reported by
Matt R. Thanks Matt!

Bug Fixes
=========

A critical bug where the last byte is lost when a connection is closed.
This issue was reported by Mike Heath. Thanks Mike!

Upcoming Releases
=================

Unless a major issue is reported within the next iteration, Netty
3.0.0.CR4 will become a GA release. Please don't worry too much even if
the documentation is far from perfection. The documentation will always
be up-to-date online even after the GA is released with incomplete
documentation, and the subsequent releases will contain the latest user
guide and API reference as usual.

Netty 3.0.0.CR3 released - Test coverage!

2008-08-28T18:08:12Z

Hi folks,

Netty 3.0.0.CR3, the third release candidate of Netty 3.0.0 has been
released. In this release, I wrote a lot of test cases to achieve more
than 75% test coverage, and it's 78% now. You could now safely assume any
noticeable bugs have gone away. Thanks to the test cases, various bugs
were found and fixed. Please visit our web site to download it:

GA is coming!
=============

There were some subtle improvements here and there, but they are not as
important to be highlighted in this announcement. Shorter announcement
indicates we are very close to the GA release. From now on, I will focus
on documentation. Please stay tuned!

Project registered in Ohloh
===========================

I have added the Netty project to Ohloh.net, which provides various stats
for an open source project. If you are using Netty, you could click 'I
use this' button on the right side of the page:

* http://www.ohloh.net/projects/netty

You can also see my personal stats here - I wouldn't mind if you are going
to give me some kudo for a good reason ;)

Netty 3.0.0.CR2 released

2008-08-21T00:44:26Z

Hi folks,

Netty 3.0.0.CR2, the second release candidate of Netty 3.0.0 has been
released. This release fixes various bugs including the performance
degradation in the NIO transport. It also features reduced application
exception stack trace, which will be explained in this release note.

ChannelBuffer.EMPTY_BUFFER moves to ChannelBuffers
==================================================

This is a backward incompatible change which had to be introduced in this
release unfortunately. The change is as simple as replacing
'ChannelBuffer.EMPTY_BUFFER' with 'ChannelBuffers.EMPTY_BUFFER' though. I
hope this is the last backward incompatible change in 3.0.

Performance improvements
========================

The NIO transport suffered with a performance dropdown when a user writes
a message from a user-thread, which is not an I/O thread. 3.0.0.CR2
minimized resolved this problem by reducing the number of unnecessary NIO
calls. Also, tiny optimizations were done here and there to squeeze out
even more throughput while maintaining very low latency.

Exception stack trace simplification
====================================

The stack trace of an exception which is created inside a ChannelHandler
has been unnecessarilly long, making an application debugging difficult.
This is a typical problem of event-driven frameworks which implement the
chain of responsibility pattern. 3.0.0.CR2 shortened the stack trace of
an application exception dramatically while not losing an important stack
trace element.

Micellaneous

Besides the notable improvements mentioned above, a number of bugs were
fixed in this release. For the detailed changelog, please visit here:

Netty 3.0.0.CR1 released - the first release candidate!

2008-08-13T20:39:37Z

Hi folks,

I'm so excited to announce Netty 3.0.0.CR1, the first release candidate of
Netty 3.0.0. There were a number of improvements include a couple bug
fixes in this release. Netty 3.0.0.CR1 is also the first release since
Netty moved its nest from GoogleCode and Google Groups to JBoss.org.
Please vitie the new web site to download it:

Changes in package names
========================

The package name has been changed from net.gleamynode.netty to
org.jboss.netty. Also, Maven groupId has been changed to
org.jboss.netty. There was no change in package structure itself, so
fixing compilation errors should be as easy as reorganizing imports in
your IDE.

More convenient ChannelBuffer
=============================

A number of convenience methods were added to ChannelBuffer. The
noteworthy additions are the access methods for unsigned integers and
Strings. These methods should help a user to access more complicated
message structure conveniently.

Pluggable Logging
=================

A user can decide what logging framework Netty should use now. Please
refer to the JavaDoc of org.jboss.netty.logging.InternalLoggerFactory for
more information with an example.

Bug fixes
=========

The following two bugs were reported by the community and fixed.

* The race condition in SslHandleer has been fixed, thanks to
hawkins.steven
* A bug where DelimiterFrameDecoder fails to find a delimiter has been
fixed, thanks to noteric
