[SR-Users] KEMI routing script Python exceptions with empty traceback

[Michael Loughrey]

Thanks for the tip Anthony. I do indeed have a couple of ksr_ routines
returning no value.

>From kamailio.cfg

####### Routing Logic ########

modparam("xhttp", "event_callback", "ksr_xhttp_event")
modparam("htable", "event_callback_mode", 1)
modparam("htable", "event_callback", "ksr_htable_event")
modparam("dialog", "event_callback", "ksr_dialog_event")
modparam("app_python", "load", "/usr/local/etc/kamailio/routing.py")
cfgengine "python"

In routing.py


   ksr_dialog_event(self,msg,evname)

   ksr_htable_event(self,msg,evname)


are not returning values. I will correct these to always return 1.
Hopefully that resolves the issue. Could you confirm that a return
value of 0 from routes such as those set in


KSR.tm.t_on_failure

is the equivalent to exit & drop.


Cheers

Mike


ksr_dialog_event
