[sr-dev] Reseting a pseudo-variable for each new request/response

Hi, in a module I'm writting I export a script function which gives value to a new pseudo-variable. This pv is stored in a global variable into each worker process. I don't know how to solve this issue: - A request is handled by worker-1. - The script calls to the module function so the pv is filled (it's value is stored in a global str within the process). - Later in the script I can access to $new_pv (it reads the global str in the pv_get_new_pv() function). - The request processing ends (i.e: t_relay). - After some time the same worker-1 receives a new request. - If the script reads $new_pv (without calling the module function before) it will get the value generated during the previous SIP request. Of course the script configuration shouldn't try to read $new_pv without calling first to the exported function, but anyhow this could happen (due to a bad script file). Is there an ellegant way to avoid this? This is, I would like that when a process receives a request (or a response) $new_pv gets automatically reseted (to NULL), prior to executing the script logic. In this way accessing to $new_pv without calling the module function would return an empty value. Is it possible? how do other modules handle this case? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>
