I think I'll try to produce a old blocking IO based UDP server For see how it performs and if the inner code of MINA can easily accept blocking transports. We have to deliver a BioUdpServer and a BioTcpServer anyway. (and the client too). That would be a great addition to a first milestone, but if it's not ready, we can add it for M2.

The type of clients and servers are defined in the BenchmarkFactory class. You have to add a Netty4_udp and Netty4_tcp. Then the BenchmarkClientFactory and BenchmarkServerFactory class have to be augmented to handle the Netty4 clients and server for TCP and UDP. Those are pretty straghtforward modifications. Then you have to write the real flesh : in the nio/tcp and nio/udp packages, you have to add the classes to create the Netty4 client and server for UDP and TCP. This is where the initialization is done. Last, not least, the tests themselves are in some new classes names [Netty4|Netty3|Mina3]ClientVs[Netty4|Netty3|Mina3]Server[Tcp|Udp]BenchmarkBinaryTest. Those new classes just have to reference the correct type defined in the BenchmarkFactory. Thanks a lot of the help ! -- Regards, Cordialement, Emmanuel Lécharny www.iktek.com

[jira] Created: (DIRMINA-780) Writing null objects to the Session should raise an Exception
Writing null objects to the Session should raise an Exception - Key: DIRMINA-780 URL: https://issues.apache.org/jira/browse/DIRMINA-780 Project: MINA Issue Type: Improvement Components: Core Reporter: Norman Maurer When using MINA in JAMES we saw malformated packets when processing POP3. This was a cause of a bug in our code which wrote a null object to the session. Unfortunally MINA don't throw an exception in this case and just write garbage to the session. We only found the bug because we have a netty implementation too which throws a NullPointerException in this case. I think MINA should do something similar.. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

2010/4/9 Ashish paliwalash...@gmail.com:
Did some more investigation. Here is one of the strange observations
Most of the hanging DefaultWriteRequest have this message 451 Unable
to process smtp request..
Can't analyze all of them, but saw content of close to 100 objects.
All of them had the same content
This error is coming from org.apache.james.smtpserver.mina.SMTPIoHandler
Line:94
if (session.isConnected()) {
session.write(new SMTPResponse(SMTPRetCode.LOCAL_ERROR, Unable to
process smtp request));
}
Also, from the heapdump, all the WriteRequests are for a session
(id=13609), and they are hanging there :(
so seems like we have a hanging session.
Any thoughts?
Will try to reproduce this problem at my end. Some logs might be of help.
thanks

Re: Spring Integration
Hi Andreas, I'm not a mina dev but I'm sure they love patches which make the code more usable ;) Bye, Norman 2010/4/7 Andreas Sahlbach andreas.sahlb...@gmail.com: Hi guys! I am a new user of your framework (great stuff!) and I have a short question regarding the spring framework. I am using mina 2.x and noticed that you removed a lot of special spring stuff in favor of a more general support for injection frameworks. Still there are a number of classes in the framework that are pretty spring-unfriendly and cannot be used from within spring without user modifications (like extending them or wrapping them). So my question is: What is your midterm plans regarding spring integration? Are you going to modify your classes so that they can be easily from within spring? If so, should I file a bug (with patch) for classes that don't work currently? Or are you going to implement more helper classes in the xbean package? I am referring for example to DemuxingProtocolCodecFactory or DemuxingIoHandler, which can't be initialized easily from within spring. Best regards, Andreas -- Andreas Sahlbach

JAMES OOM, maybe the cause of MINA ?
Hi all, we at JAMES use MINA since a while now for our socket stuff. After doing some stress tests we encountered some OOM Exceptions. The same was seen by one of our users which use JAMES trunk.

I don't know what version of MINA you are refering to, nor which class (we

there are no such private method anymore.

JAMES switched to use MINA for Sockets
Just some heads-up, JAMES (james.apache.org) recently changed the whole socket-code to use MINA 2.0.0-RC1 only. MINA now replaces the old socket implementation which was cornerstone-sockets. I must say so far it really works perfect for IMAP/SMTP/POP3. Thx again for the hard work and we are looking for the final 2.0 release! Bye, Norman
Re: [MINA 3.0] Initial thoughts on FilterChain

Rename IoFilterChain as IoChannel - it gives a more clear picture and is easy to understand like imagine as a Channel with multiple stages aka IoFilters. This came while I was drawing on paper to design something. I propose IoPipe/IoPipeline, because for me a bunch of filter stacked on each other is a Pipe in the Unix meaning. 2. Have captured a couple of API's that are core to IoChannel IoSession getSession(); IoFilter getHead(); IoFilter getNextFilter(IoFilter currentFilter); ListIoFilter getAll(); void addFilter(String name, IoFilter filter); void addAfter(String baseName, String filterName, IoFilter filter); void removeFilter(String filterName); There are a lot more API's in current implementation. I am not sure if we need replace API or not. Also do we need the Generics version of these API's or its fine without them? This is just the initial list. Will checkin the files once the name change is OK with everyone.

After it start again all works again. I attached the LoggingFilter and see that MINA really stops sending data in this time. I only not understand why... I used a StreamWriteFilter to stream write the InputStream directly. I used a writeBufferSize of 4 ( I had bad results with a bigger one). Anything I miss ? Any idea why mina stops the write ? Maybe the buffer of the device is just full ? bye Norman maybe a solution : you can disable Nagle's algorithm by a call to SocketSessionConfig.*setTcpNoDelay*, e.g.: ((SocketSessionConfig) connector.getSessionConfig()).*setTcpNoDelay*(true) http://en.wikipedia.org/wiki/Nagle_algorithm Pierre-Louis On Tue, 10 Jul 2007 13:32:52 +0200, Stefano Bagnara [EMAIL PROTECTED] wrote: Hi Norman, As someone else already replied in udp you have to manually check for ordering and retransmissions. The is no raw protocol for mp3 streaming, so you should read the manual for the appliance you bought and maybe it does explain how to manage the protocol.

SocketAcceptor and Spring
Hi all, im using mina in a test project at the moment. Now after reading the docs about the ThreadModel i want to change the used SocketAcceptor like descripted in the documentation. In the docs is: IoAcceptor acceptor = new SocketAcceptor(Runtime.getRuntime().availableProcessors() + 1, Executors.newCachedThreadPool()); Now i wonder how i can do this with Spring.. Anyone can help ? bye Norman
