Hello,
the script reload mechanism relies on a counter (version number) stored
in shared memory. It is set to 0 when kamailio start and increased with
each RPC reload command.
Each worker process has a copy of the value in a local variable.
When a worker process is executing a script, it checks if the local
value matches the one from shared memory. If different, then it should
reload the script before executing it.
This is how is done for Lua, JavaScript and Squirrel. I tried to
implement the same for app_python, but I couldn't make it work properly
due to lack of (embedding) python experience.
Cheers,
Daniel

Hi list,
I am looking at the python script reload functionality exposed by the
rpc command "app_python.reload" and implemented by the function
app_python_rpc_reload.
The implementation increments a version number and calls
apy_reload_script(). But it looks like apy_reload_script() would be
run invoked in the process where the RPC server lives rather than the
children.
How is it sent to the workers for invocation?
I think I am misunderstanding how the RPC server works: how do you
differentiate between RPC functions meant to be executed by the master
vs sent to all the slaves?
Thanks
Anthony
