Hello, Kamailio version 5.4.4. Kamailio segmentation fault after kamctl rpc dialplan.dump <dpid>, when dialplan includes variables in the replacement expression (repl_exp) field. Please see attached corefile.
Thank you, Julia.
Hello,
are you able to get a core file for the crash? If yes, then send here the output of gdb command "bt full" to see where the crash happens and try to fix it.
Cheers, Daniel

Hello,
ohhh, indeed -- I thought it was the corefile itself, which cannot be investigated on other system than the one generating it.
Cheers, Daniel

Hello,
did you change the database structure? Because the crash seems to be because attrs field is NULL, but database schema should prevent it. Or, maybe you use a database backend that cannot enforce that, which one do you use (db_myql, ...)?
Cheers, Daniel

Hello Daniel,
I use mysqldb. I have added the default value "" to column "attr" and It's working now.
Thank you so much! Julia.

Hello,
probably the module code needs also some updates, it is rather old and likely designed for db backends that enforce non-null values, like in the create statement:
* https://github.com/kamailio/kamailio/blob/master/utils/kamctl/mysql/dialplan...
So it does not do much extra checks in the code, but these days there are other db connectors that may not have strict schema implementation like db_redis or db_mongodb.
For now, I pushed a push a patch to jsonrpcs module to print 'null' value in jsonrpc response, when the value passed from other modules to it is C-NULL. This should prevent (hopefully) the crash from happening, even you revert back to have null value in database:
* https://github.com/kamailio/kamailio/commit/c48e409b741821fa470788b3bca0ead3...
I will have to check the ctl and xmlrpc modules to see what they do in similar cases, to cover also the use of kamcmd for the same situation.
Cheers, Daniel
