[kamailio/kamailio] Presentity tabla, faster update when drop TCP/TLS connection (#915)

by jresende

Hello, I'm testing kamailio with a SIP client with presence support, when I get a connection drop from a client (i.e when the client lost the access to the Internet connection) I do not receive the change in the status to offline immediately, I just received when the timeout from the presentity database finishes. I know that I'm able to change the expiry parameter from the presentity table, but that increases my battery consumption and the data exchange, the same happens if I reduce the publish interval on the client side. The connection with the server are connected with the TLS or TCP. @miconda Suggested that a solution could be: "For TCP/TLS, what can work, it's to use tcpops module which can execute an event route when a tcp/tls connection is dropped. If you track the association of connection id with the call-id of the presence publish, then you may be able to do some tricks and lower the expires of the published presence state. I haven't had the time to see what's possible there, but could worth investing. An alternative would be to enhance presence module to behave as registrar/usrloc (which can delete contact records on connection drop) to expire documents when tcp/tls connection is closed (not sure if anyone already added it)." -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] support valgrind when *_MALLOC is used (#949)

by Victor Seva

As explain at https://www.kamailio.org/wiki/tutorials/troubleshooting/memory#pkg_with_sys… valgrind can be used to check memory leaks if kamailio is compiled without ``*_MALLOC``. I would like to support valgrind even if kamailio is compiled to use its own memory managers. In order to archive this, valgrind has to be informed of how those managers control the memory as described at http://valgrind.org/docs/manual/mc-manual.html#mc-manual.mempools -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Allow function set_advertised_address to receive variable as parameter (#2137)

by pwakano

### Description Currently the functions set_advertised_address and set_advertised_port only accept strings as parameters. Trying to use it with variable causes an error. Having the function using a hard coded value is not a good practice and in order to add flexibility to the script in different installations it would be nice to have this function accepting variables. Also, the 'advertise' option on the 'listen' parameter is not always desired because it apply for all messages sent via the socket, and there are situations where different advertised IP for the same interface are necessary. ### Expected behavior set_advertised_address should receive a variable as parameter and use its value to change the SIP headers. ### Actual observed behavior Kamailio won't start if set_advertised_address is used with a variable due to script parse error or it will set the SIP message with the literal string "$var(test)" for example, instead of using the value of $var(test). ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` # kamailio -v version: kamailio 5.2.2 (x86_64/linux) 67f967 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 67f967 compiled on 11:40:41 Mar 11 2019 with gcc 4.8.5 ``` * **Operating System**:  ``` # uname -a Linux voice-conn-kamailio-1 3.10.0-514.21.2.el7.x86_64 #1 SMP Tue Jun 20 12:24:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] app_ruby: print backtrace when ruby exception occurs (#1766)

by Fatih Orhan

### Description Hello, When there is an error in my ruby script, app_ruby prints exception message without a stack trace, like this: ``` Dec 14 16:25:17 servername /usr/sbin/kamailio[24313]: ERROR: app_ruby [app_ruby_api.c:105]: app_ruby_print_last_exception(): exception: wrong number of arguments (1 for 2..3) Dec 14 16:25:17 servername /usr/sbin/kamailio[24313]: ERROR: app_ruby [app_ruby_api.c:1078]: app_ruby_run_ex(): ruby exception (6) on callback for: ksr_request_route (res type: 17) ``` Altough this message tells what is the error, it doesn't tell **where** the error happened, so it's hard to find the source of the problem. In ruby, exceptions have _backtrace()_ method returning stack trace as an array of strings. It would be really helpful if app_ruby also call this method and append its result to error message. ### Reproduction in kamailio.cfg ``` loadmodule "app_ruby.so" modparam("app_ruby", "load", "/etc/kamailio/ruby/routes.rb") cfgengine "ruby" ``` in /etc/kamailio/ruby/routes.rb ``` def some_method(param1, param2) end def ksr_request_route some_method(1) end ``` ### Expected behavior ``` Dec 14 16:46:24 servername /usr/sbin/kamailio[24314]: ERROR: <core> [core/kemi.c:87]: sr_kemi_core_err(): wrong number of arguments (1 for 2): /etc/kamailio/ruby/routes.rb:1:in `some_method' /etc/kamailio/ruby/routes.rb:4:in `ksr_request_route' ``` #### Actual observed behavior ``` Dec 14 16:45:42 servername /usr/sbin/kamailio[24311]: ERROR: app_ruby [app_ruby_api.c:105]: app_ruby_print_last_exception(): exception: wrong number of arguments (1 for 2) ``` ### Possible Solutions Relevant code seem to be here: https://github.com/kamailio/kamailio/blob/master/src/modules/app_ruby/app_r… I found example C code to print stack trace here but couldn't figure out how to integrate to app_ruby: http://zoo-project.org/svn/trunk/zoo-project/zoo-kernel/service_internal_ru… Equivalent ruby code would be (this code is not idiomatic, my aim is to provide C-like ruby code): ``` def some_error_generating_method method_taking_two_params(1) rescue => exception message = exception.to_s() + "\n" stack_trace = exception.backtrace() for line in stack_trace message = message + line + "\n" end print(message) end ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.2.0 (x86_64/linux) 535e13 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 535e13 compiled on 10:26:34 Nov 28 2018 with gcc 4.8.5 ``` * **Operating System**: Centos 7.2 64bit ``` Linux servername 3.10.0-327.28.2.el7.x86_64 #1 SMP Wed Aug 3 11:11:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
