Always return null when get data from tokyo tyrant about memcached-java-client

[newroot]

which version are you using? 2.5.1 or 2.0.1?
I will try to reproduce this issue with the version 2.5.1 together with latest tykyo tyrant as soon as possible.

Hi yheart:
I have reproduced the problem with 2.5.1 as well. However, during the debug, I have found the flag number returned by ttserver always is 0 which not implemented as same as Memcached server. you can find more about the memcached protocol here: http://code.sixapart.com/svn/memcached/trunk/server/doc/protocol.txt
Therefore, base on the return flag number, our client is not able to retrieve the value. That is what we found so far and we will try to figure out a way to get around with it in the future.

Thanks a lot for letting us know about the problem.

Hello yheart:
During the research, I have found since our memcached client distinguishes different object type and set different different flag value to improve the performance, SpyMemcached stores all values as object only which will reduce the performance. In source code, if you change the code in class AscIIClient.java line 373, int flag = 0, using our client to set value and get value, it will works very well. However, the performance will be lower than b4.

Because tykyo tyrant doesn't support flag as stock memcached, we will close this issue.
