Using gdb I've figured out that in mod_python.c:281:

...

result = PyEval_CallObjectWithKeywords(function, arg, (PyObject *) NULL);

Py_DECREF(function);

...

variable result is always null when a python script trying to use the session run the first time right after freeswitch startup.

That will make it enter the else logic in line 291 in the same file ending with a crash.

I'll still have to drill more to find out why this is happening now.

Anyone has a clue on what's going on?

This is the output after calling the script right after start:

All the following script calls work just fine.

Note: If you want to test the code snippet i've added before don't forget to add:

import freeswitch

Looking forward to hear from you.

Best Regards,

Hi guys.

I've reported this before and i can tell that it is still happening in the latest v1.4.

How reproduce:

just create a dialplan that calls a python script
dial that dialplan entry

Example code (works with anything that invokes session):

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from __future__ import absolute_import
# http://docs.python.org/whatsnew/pep-328.html

def handler(session, args):
freeswitch.consoleLog("notice", "Testing123...")
freeswitch.consoleLog("notice", "Dumping current CDR INFO")
freeswitch.consoleLog("info", str(session.getXMLCDR()))
freeswitch.consoleLog("notice", "The END!")

mod_pyhton crashes everytime the script is called right after a freeswitch start (the very first time session is invoked inside a mod_python python script).
After the first time (error), everything starts to work just fine.
This doesn't happen in e6b8b3e4f2deac73547bc9b9a2cb3e1d3147d101 from v1.2.stable

Should i open a jira on this?
