Hello,
what is the kamailio version you are running? At some point there was an
issue with path to the python script due to changes done to it by some C
functions. Should be fixed in latest 3.1 and 3.2 branches anyhow, but
let's see what you use so we don't hunt solved cases.
Cheers,
Daniel

Hi Timo,
Yes, I have investigated it a bit more. The problem is not that warning it is
an error which stops the Kamailio to start..
The error is
"0(25062) DEBUG:<core> [sr_module.c:885]: DEBUG: init_mod: app_python
0(25062) ERROR: app_python [python_mod.c:158]: cannot import handler
0(25062) ERROR:<core> [sr_module.c:889]: init_mod(): Error while
initializing module app_python (/usr/local/lib64/kamailio/modules/app_python.so)
ERROR: error while initializing modules"
I have tried to investigate a bit more, and the problem is that it is not able
to find the handler.py file..
The error is occurring in init_mod() function which is trying to call a function called
"PyImport_ImportModule(bname)" function.. The file tries to set the absolute path in the
start .. The absolute path was setup with reference to "sip-router" folder which is old..
So, I changed the path to Kamailio folder.. But, the module can't be loaded...
To investigate this loading problem, I have seen the functions being called. PyImport_ImportModule takes the
name of module to load.. if "." is used that specifies the sub modules..so, this function is being
passed just the word "handler".. The absolute path in the start is setup for a file called
"handler.py".. This file is trying to push the directory path in the path as well, but I think
maybe there is some problem lying.. I tried to load by passing full path name to PyImport_ImportModule() as
well but, in vain..
Hope this clarifies things more..
Regards,
Nasir

I am trying to enable the app_python module in Kamailio to run a
simple python script externally parallel with Kamailio proxy,
While I try to load the module "app_python.so" in configuration file,
the Kamailio server fails to start.. I can't see what is the problem ..
The steps, I am following are that:
- Script written in python saved in home directory.
- Loadmodule "app_python.so" statement in configuration file.
- Modparam("app_python", "script_name", "location of script")
- Python_exec("function", "parameters list") ..
I have also tried to check the Kamailio configuration option, It gives
following warning,
0(2942) WARNING:<core> [sr_module.c:584]:
/usr/local/lib64/kamailio/modules/app_python.so: exports dlflags
interface is deprecated and it will not be supported in newer
versions; consider using mod_register() instead
Is there no other error message? What you provided is just a WARNING which
shouldn't be a show stopper.
