[infinispan-issues] [JBoss JIRA] Updated: (ISPN-794) Memcached server should treat unsigned numeric values as such

Galder Zamarreño updated ISPN-794:
----------------------------------

        Summary: Memcached server should treat unsigned numeric values as such  (was: Memcached server should treat flags as unsigned 32bit integers)
    Description: 
As indicated by Michal:

""flags" argument used with memcached storage commands is described as 16 or 32 bit unsigned integer. 
if I understand it correctly 16bits is recommended for clients for compatibility with older memcached implementations, but current memcached implementation should support 32bits. 

original memcached implementation allows range: 0 .. 4294967295 (actually also some negative numbers, but that's a bug I guess: http://code.google.com/p/memcached/issues/detail?id=168) 
we allow range: -2147483648 .. 2147483647"

Apart from flags (unsigned 16 bit int), also check:
- incr/decr value (unsigned 64 bit)
