Re: [sr-dev] possible bug on kemi dlg_ontimeout

Hello, indeed keeping route block index in unsigned it can create problems. I pushed a patch for it: - https://github.com/kamailio/kamailio/commit/6c557efc1b9cb8c880a05235c94780b… Can you try and see if now works ok? If yes, it will be backported.

If i used KSR.dialog.var_sets to set $dlg_ctx(timeout_route), I saw that on a dialog timeout, the dlg_ontimeout event route was not triggered, and only the dialog callback was executed with evname dialog:end. (only executing event_route -1 on state 5) So i'm guessing that the kemi dialog var_sets is for $dlg_var only (¿?) Anycase, If i used KSR.pv.sets, i saw the kamailio was crashing ..... 16(5579) DEBUG: dialog [dlg_hash.c:1013]: dlg_ref_helper(): ref dlg 0x7f9a961f5f90 with 1 -> 3 16(5579) DEBUG: dialog [dlg_handlers.c:1589]: dlg_ontimeout(): executing route -1 on timeout 22(5645) CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 8 22(5645) DEBUG: <core> [core/tcp_main.c:3762]: handle_ser_child(): dead child 16, pid 5579 (shutting down?) .... Adding some debug, i could see that the call was not attempting the kemi function of line 1598 of dlg_handlers.c, and was trying the code i think was for native on line 1593. We think the issue is that the toroute is defined as unsigned dlg_hash.h: unsigned int toroute; /*!< index of route that is executed on timeout */ but after that when setting $dlg_ctx(timeout_route) with pv module, it tries to compare an integer being unsigned, so it's always true and never uses kemi with this change we made it work + if ((int)(dlg->toroute) > 0) { + /*if(dlg->toroute>0) {*/ but i don't know maybe there is a better way to do it. best regards david _______________________________________________ Kamailio (SER) - Development Mailing Listsr-dev@lists.kamailio.orghttps://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-dev -- Daniel-Constantin Mierla -- www.asipto.comwww.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - March 9-11, 2020, Berlin - www.asipto.com Kamailio World Conference - April 27-29, 2020, in Berlin -- www.kamailioworld.com
