[kamailio/kamailio] Wishlist #234: URI transformation to pick up URI scheme (#592)

by Olle E. Johansson

I would like the URI transformations to be more generic so one can pick up the URI scheme, like HTTP: or TEL: Just an idea --- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/592

[kamailio] PID file permissions (#231)

by Arsen

ENV: Debian 8 So on most Linux systems the /var/run folder is a tmpfs and after which clears after each reboot As I try to start up kamailio after a reboot through kamctl I get the following error. "ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed" Because kamailio does not have the permission to write to the /var/run folder as the kamailio user. Would it be possible to add in the "kamctl" code a section where the SPECIFIED PID LOCATION (/var/run/kamailio) is checked and if it does not exist create it as the root user and chown it to the SPECIFIED USER (kamailio)? The way I have patched it for now is to create a init script that creates a /var/run/kamailio folder and chmods it to kamailio:kamailio Thanks everyone! --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/231

[kamailio/kamailio] Enabling DMQ cause high CPU usage (#822)

by Soapnix

Hi all! We trying to use two instances of kamailio on FreeBSD, kamailio was build from master branch. If I enables DMQ, 2 threads (pids) start utilize CPU, less than minute it's up to 100% (on a both servers). At that time kamailio successful handle calls, dmq and usrloc replication wokrs fine. While trying to understand what happens I got this debug info - something happens and K. cycles on shed_yeld() func. All additional info I put into attachments: [gdb_output.txt](https://github.com/kamailio/kamailio/files/528881/gdb_outpu… [kamailio.log.gz](https://github.com/kamailio/kamailio/files/528879/kamailio… [kamailio.txt](https://github.com/kamailio/kamailio/files/528883/kamailio.tx… [kdump.txt.gz](https://github.com/kamailio/kamailio/files/528880/kdump.txt.g… [ktrace.out.gz](https://github.com/kamailio/kamailio/files/528878/ktrace.out… [top_output.txt](https://github.com/kamailio/kamailio/files/528882/top_outpu… -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] TMX module statistics reset not working (#820)

by atilamtm

I'm currently using version 4.4.2 and am having trouble trying to reset the statistics in the TMX module. According to its documentation, all statistics except “inuse_transactions” can be reset. Checking the tmx_mod.c files for the statistics definition, I saw that the STAT_NO_RESET flag wasn't used for any statistic listed there (which seems odd because I think it should have been set for the inuse_transactions statistic): `static stat_export_t mod_stats[] = { {"UAS_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_uas_trans }, {"UAC_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_uac_trans }, {"2xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_2xx }, {"3xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_3xx }, {"4xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_4xx }, {"5xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_5xx }, {"6xx_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_6xx }, {"inuse_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_inuse }, {"active_transactions", STAT_IS_FUNC, (stat_var**)tmx_stats_trans_active}, {"rpl_received", STAT_IS_FUNC, (stat_var**)tmx_stats_rcv_rpls }, {"rpl_absorbed", STAT_IS_FUNC, (stat_var**)tmx_stats_abs_rpls }, {"rpl_generated", STAT_IS_FUNC, (stat_var**)tmx_stats_rld_loc_rpls}, {"rpl_relayed", STAT_IS_FUNC, (stat_var**)tmx_stats_rld_rcv_rpls}, {"rpl_sent", STAT_IS_FUNC, (stat_var**)tmx_stats_rld_tot_rpls}, {0, 0, 0} };` All seems ok, but when I try to reset the stats, the command simply doesn't work. The values remain unaltered. The clear command doesn't work either, it just returns the current values. -- You are receiving this because you are subscribed to this thread.

Outbound flow failure handling merged to master

by Hugh Waite

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!
