Hanson Char commented on DIRMINA-224:
-------------------------------------
I can see why the Decoder needs to be created with new instances.
However, the Encoder is entirely stateless. So singleton will work just fine. What am I missing here ?

Hanson Char updated DIRMINA-224:
--------------------------------
Attachment: Mina-0.9.4-bug.jar
I ported the test harness to use Mina 0.9.4 and it seems the problem went away.
Attached is the 0.9.4 version of the same test harness.

Hanson Char updated DIRMINA-224:
--------------------------------
Attachment: Mina-0.8.2-bug.jar
You can run the test on Linux 7.2 to see the problem:
Type:
jar xf Mina-0.8.2-bug.jar
ant
(Apache Ant version 1.6.5 compiled on June 2 2005)
The junit test almost always failed on Linux 7.2., but never faile on Windows XP.
In one sample run:
1) the expected "message Testing 212" gets corrupted to become "ing 212"
2) the expected "pingpong" message sometimes gets corrupted to become "g"

[jira] Resolved: (DIRMINA-224) Data Corruption
Posted by "Trustin Lee (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/DIRMINA-224?page=all ]
Trustin Lee resolved DIRMINA-224:
---------------------------------
Resolution: Invalid
I found your Decoder implementation is invalid. Basically it shouldn't work with 0.9.4 under high load because your implementation doesn't take account into the case that a message is splitted into more than one packets. Please try to replace it with TextCodecFactory which is introduced in 0.9.x.

Trustin Lee commented on DIRMINA-224:
-------------------------------------
Plus, please try to create one encoder/decoder instance per session. You can create a singleton that can process multiple sessions at the same time, but it's quite hard to implement. Please refer to the 'reverser' example included in 0.8.2.
