fork process in kamailio
by Stefano Poli 04 Oct '10

04 Oct '10

Hi, I have to modify kamailio to add QoS to presence module. I have to fork a new process that is allowed to access presentity table into database but with the classik fork() function i cannot access to it. Have I to do something in particular? Thanks! -- Stefano Poli

t_newtrans() more user friendly
by Iñaki Baz Castillo 04 Oct '10

04 Oct '10

Hi, I want to create a transaction prior to performing some DB queries or any other type of communication with external processes. I want to create the transaction manually (t_newtrans) before invoking t_relay, so if something blocks the request processing for a while, a retransmission would not trigger all the DB queries again. The problem is that changes to the transaction done after invoking t_newtrans() are not saved within the transaction (this is: adding headers, setting flags, AVP's....) which makes t_newtrans() function really ugly and anti-user-friendly. So my question is: couldn't t_relay() update transaction information in case there are changes after calling t_newtrans()? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>
