Hi!

I'm trying to use perlvdb module but seems that it's not working. Seems that needed functions are not exported correctly:

kamailio[11525]: ERROR:<core>  [db.c:79]: module db_perlvdb does not export db_use_table function

Looking at perlvdb.c one can see that module exports it's functions as "perlvdb", not "db_perlvdb". But changing "perlvdb" to "db_perlvdb" results in segfault when running:

kamailio[31336]: segfault at 1 ip b7365e3a sp bfa82fb0 error 4 in perlvdb.so[b7362000+6000]

Do I misunderstand something completely or there is a bug? Anyone actually tried using this module or it just sits there forgotten?

out of curiosity, why are you using it? The module pretty much sits there, apart of the original developer that did it for diploma thesis I haven't seen much activity around the module.

I'm using it because I need to tie auth to custom storage (actually json-rpc requests to billing system). Probably I can use lua but not sure and perlvdb concept is pretty nice. Any other ideas how to do this?

How to you set the db_url parameters for this module? You know that you have to code in perl the DB API commands in perl for particular modules before using it, right?

yes, for now I just use examples provided db_url is set like this: modparam("auth_db", "db_url", "perlvdb:OpenSER::VDB::Adapter::Auth")

When you get the segfault, do you get a core dump? If yes, send the backtrace. I will try to help if it proves to go easy, otherwise you have to dig yourself in the sources of the module, the original developer changed job and is no longer in VoIP business :-) ...

coredump? easy :) you can pick core file itself here (it's pretty heavy to send to the list): http://83.99.159.113/core.kamailio.20110418-1331

What do you mean by backtrace? log output or strace output?
