As describe in my original post:
The installed packages:
[root at host ~]# rpm -qa | grep kamai
kamailio-4.0.1-1.1.x86_64
kamailio-mysql-4.0.1-1.1.x86_
64
kamailio-python-4.0.1-1.1.x86_64
So, Kamailio 4.0.1-1.1
My understanding is that the default values are the following:
modparam("app_python", "script_name",
"/usr/local/etc/sip-router/handler.py")
modparam("app_python", "mod_init_function", "mod_init")
modparam("app_python", "child_init_method", "child_init")
But just to make sure, I added the following line in my kamailio.cfg, and
again:
[root at host ~]# cat /usr/local/etc/sip-router/handler.py
class Handler(object):
def child_init(self, y):
return 0
def mod_init():
return Handler()
When I start kamailio, I have the same error.
I also downloaded the sources and compiled kamailio with app_python support
and I have the exact same result
0(2158) DEBUG: <core> [sr_module.c:935]: DEBUG: init_mod: app_python
0(2158) DEBUG: <core> [sr_module.c:935]: DEBUG: init_mod: db_mysql
0(2158) ERROR: <core> [sr_module.c:939]: init_mod(): Error while
initializing module db_mysql (/usr/lib64/kamailio/modules/db_mysql.so)
0(2158) ERROR: app_python [python_support.c:132]: mod_init: Unhandled
exception in the Python code:
AttributeError: init_modules() has failed
0(2158) ERROR: <core> [sr_module.c:939]: init_mod(): Error while
initializing module app_python (/usr/lib64/kamailio/modules/app_python.so)
ERROR: error while initializing modules
Is this a bug with Kamailio ?
