[OpenSIPS-Devel] [opensips] cachedb_memcached cache_fetch returns -2 even for empty value (#522)

[apsaras]

The problem found is that the cache_fetch function returns -2 in case MemCached does not respond and in case where MemCached returns an empty value. In such case, we are not able to distinct between ERROR and Empty value so the following script is not working

 $var(mc_first)=cache_fetch("memcached:first","$avp(num)",$avp(net));
 
if($var(mc_first)==-2)
{
    $var(mc_second)=cache_fetch("memcached:second","$avp(num)",$avp(net));
     
    if($var(mc_second)==-2)
    {
          avp_db_query("$avp(num)","$avp(net)","1");
     }
 }
