Re: [sr-dev] [kamailio/kamailio] cfgt: crash trying to get $T_rpl() value using pv_get_spec_value() (#2479)

by Daniel-Constantin Mierla

Seeing it happens when an ACK was received by trying to dump $T_rpl(...), the docs specify it has to be used in failure route blocks, not being the case in this crash situation: * https://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#t_rpl_pv I added safety checks in the code to catch such cases and return $null. -- You are receiving this because you are subscribed to this thread.

Re: [sr-dev] [kamailio/kamailio] cfgt: crash trying to get $T_rpl() value using pv_get_spec_value() (#2479)

by Daniel-Constantin Mierla

Not familiar with the cfgt module, when is it executed in this case? I can see in the trace that it relies on some debugger api, maybe you can present more details about execution context to understand what happens behind the module. -- You are receiving this because you are subscribed to this thread.
