when adding an existing key memcached server failed

[GoogleCodeExporter]

What steps will reproduce the problem?

From php connect to memcachedb via Memcache() class 

1. add a key with a value
2. try to add again the same key 

What is the expected output? What do you see instead?
-normaly this should return false

Result: PHP Notice:  add(): marked server 'localhost:21211' as failed in ... 

What version of the product are you using? On what operating system?

Berkeley DB 4.6.18
libevent 1.4.0-beta
memcachedb-0.1.0
Linux

in memcachedb.h

#define END_LEN 5001
#define END_LEN_STR "5000"

-ps aux

php test:
<?php

$memcache = new Memcache;
$memcache->addServer('localhost', 21211);

$memcache->add('keya','vala');

This might be relevant to the issue above,

Telneting into memcachedb 0.1.0:

root@x:~# telnet localhost 21211
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
add a1 0 0 5
aaaaa
STORED
add a1 0 0 6
bbbbbb
NOT STORED

Telneting into memcached 1.2.2

root@x:~# telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
add a1 0 0 5
aaaaa
STORED
add a1 0 0 6
bbbbbb
NOT_STORED

There's a notable difference between the response from the servers on the 
second add:
memcached replies with "NOT_STORED"
memcachedb replies with "NOT STORED" (notice the missing underscore)
this probably confuses the client since it's not the standard memcached 
response:

This is bug, and we now have a new bugfix release.

Hi. I *think* that this code fix still needs to be checked in.

I was using 1.2.1-beta and found this bug myself. I then checked out the code 
this
morning from http://memcachedb.googlecode.com/svn/trunk/ and found that line 
663 of
memcachedb.c still has NOT_STORED.

Is there a step between the releases that cocorultimid got and subversion that 
has
been missed?
