Route $hfl negative index strange behaviour:

by Xenofon Karamanos

Hello, I am working on extending $hfl and $hflc supporting some more headers. During some experimentation, i stumbled in some weird behavior regarding $(hfl(Route)[-1]) and negative indexing of $hfl pseudo-variable. Here is a breakdown of what's happening: in kamailio.cfg: request_route { xlog("L_INFO", "Route headers hdr: $hdr(Route)\n"); xlog("L_INFO", "Route headers hfl: $hfl(Route)\n"); xlog("L_INFO", "Route headers count: $hflc(Route)\n"); xlog("L_INFO", "Route headers 0: $(hfl(Route)[0])\n"); xlog("L_INFO", "Route headers 1: $(hfl(Route)[1])\n"); xlog("L_INFO", "Route headers 4: $(hfl(Route)[4])\n"); xlog("L_INFO", "Route headers -1: $(hfl(Route)[-1])\n"); xlog("L_INFO", "Route headers -2: $(hfl(Route)[-2])\n"); xlog("L_INFO", "Route headers -3: $(hfl(Route)[-3])\n"); ... } Now when sending a SIP message containing multiple headers that have comma separated values ie: OPTIONS_MSG_2CONTACTS="OPTIONS sip:example.com SIP/2.0 Via: SIP/2.0/UDP 192.168.1.100:5060;branch=z9hG4bK123456789 Max-Forwards: 70 From: <sip:bob@example.com>;tag=123456789 To: <sip:alice@example.com> Call-ID: 987654321(a)192.168.1.100 CSeq: 1 OPTIONS Contact: <sip:bob@example.com>;expires=3600,<sip:bob2@example.com>;expires=3600,<sip:bob3@example.com>;expires=3600 Route: <sip:server1.example.com;lr;ftag=1234>, <sip:server2.example.com;lr;ftag=5678>, <sip:server3.example.com;lr;ftag=9012> Route: <sip:server4.example.com;lr;ftag=1234>, <sip:server5.example.com;lr;ftag=5678> Content-Length: 0 " the logs show the weird behavior: Negative -1 should print the last header found and so on (as stated by https://www.kamailio.org/wikidocs/cookbooks/devel/pseudovariables/#hflname-… $hdr $hfl doc). Currently, -1 prints null and -2 prints the last one, -3 second to last and so on. This is probably a bug and not the expected behavior, or am i missing something?
