Following your point I stripped the part outside
redis_destroy function.
This patch frees _redisc_rpl_list at redis_destroy function.
I think I will submit the other part to tracker as an improvement when
finished, so not to be forgotten after the freeze.

The patch is not finished, only to show a possible
solution idea.
Right now, if a user performs:
redis_cmd("srvN", "GET foo", "r");
a redisc_reply_t structure is created and assigned to name "r". If
user performs again:
redis_cmd("srvN", "GET bar", "r");
then old redisk_reply_t.rplRedis is freed with freeReplyObject and
hiredis creates a new redisReply for rplRedis field.
No problem here, then when kamailio closes that last structure would
be freed.
However, if user would perform:
redis_cmd("srvN", "GET foo", "r1");
redis_cmd("srvN", "GET foo", "r2");
redis_cmd("srvN", "GET foo", "r3");
...
those structures would not be freed from memory.
In my opinion if a user creates a lot of different replies, it should
be his responsibility to free them using e.g:
redis_free("r1")
redis_free("r2")
Most users will not need this. I am planning exporting ndb_redis
functions in an API, and use them heavily in another new module.
Regards,
Vicente.
Cheers,
Daniel

creates an API for
ndb_redis module.
The patch attached now is the correct one.

looking at ndb_redis module source code I see replies are not freed
when module is destroyed.
Also a reply is only freed when another one with same name is
performed. This could cause problems if an user would ask for
a lot of different named replies.
IMHO freeing reply list when module is destroyed and creating a new
redisc_free_reply function would solve this.
I attach a patch that compiles but not tested to show the idea.
If you agree I can perform the task, I suppose redisc_free_reply
function should also be exported in cmd_export_t module structure.
This solution would be compatible with old ndb redis module
configuration.

Vicente.
