[sr-dev] redis module support for array responses.

Hello,

I am studying the use case when a redis command returns an array (REDIS_REPLY_ARRAY type in hiredis.h from https://github.com/antirez/hiredis )

Function pv_get_redisc in kamailio/modules/ndb_redis/ndb_redis_mod.c : 365 returns a pv_value_t structure and currently only deals with REDIS_REPLY_STRING and REDIS_REPLY_INTEGER cases.

It seems looking at pvar.h that pv_value_t structure does not deal with arrays. Is that correct? So returning an array is not an option...

Then a better aproach could be changing pv_parse_redisc_name function:

right now from README in ndb_redis: after executing redis_cmd("srvN", "SET foo bar", "r"); I could get $redis(r->type) and $redis(r->value)

it could be a good idea to add options like: $redis(r->size) and $redis(r->value[Number]) when changing pv_parse_redisk_name function.

Do you think of that as a good approach?

Thanks in advance! Vicente.
