[SR-Users] memcached module trimming the leading 8 char with innodb module

[Ethan Brooks]

This is very simple Kamailio config and when i access Memcached directly
everything seem to be fine but, when accessed via Kamailio he leading 8
char is omitted.

I have included everything needed to test.

kamailio

mpath="/usr/lib/x86_64-linux-gnu/kamailio/modules/"
debug=0
fork=yes

loadmodule "tm.so"
loadmodule "sl.so"
loadmodule "pv.so"
loadmodule "xhttp.so"
loadmodule "memcached.so"
modparam("memcached", "servers", "localhost:11211")

port=80
tcp_accept_no_cl=yes
event_route[xhttp:request] {
$var(number)  = $hu;
$var(number) = $(var(number){s.substr,2,0});
xhttp_reply("200", "OK", "text/html",
        "value: $mct(@@lnp.$var(number))");
}


mysql:
source /usr/share/mysql/innodb_memcached_config.sql
 install plugin daemon_memcached soname "libmemcached.so";
CREATE SCHEMA lnp;
CREATE TABLE `lnp`.`lnp` (   `number` bigint(20) NOT NULL,   `ported`

insert into lnp.lnp   (number,ported) values   (8055551212,8053214321);

insert into innodb_memcache.containers

expire_time_column,unique_idx_name_on_key) values
('lnp','lnp','lnp','number','ported',   0,0,0,'PRIMARY');
