Hi Daniel, well, i think its not needed but wouldn't we all benefit from it ? binding the internal structure to the result instead of connection?

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Andrew Pogrebennyk (marduk) Attached to Project - sip-router Summary - our Record-Route is doubled on subsequent branches Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - All Severity - Low Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - I think I need some help understanding how the record_route() works.

To me it seems like more a bug in kamailio, because if RR is kept on private memory it should be discarded after failure route, but if the RR persists it should not be added 2nd time. 2) Is there an easy way to check if the RR header has been already added?

dispatcher module changes
by Luis Azedo 08 Sep '14

08 Sep '14

Hi Daniel, your changes to dispatcher module are great but consider these changes that i attached. 4.6. ds_is_from_list([groupid [, mode [, uri] ] ]) take 0,1,2 or 3 params for me, it does make sense to move the mode prior to uri and allow to call it separately like if( ds_is_from_list(2, 3) ) { ..... } Best

RTPengine iptables chain case sensitive?
by Peter Villeneuve 08 Sep '14

08 Sep '14

Hi, I compiled and installed deb packages as per the sipwise guide here https://github.com/sipwise/rtpengine. After running modprobe xt_MEDIAPROXY and iptables -I INPUT -p udp -j MEDIAPROXY --id 0 the new chain created is mediaproxy (lower case). Isn't iptables case sensitive? I'm not sure that it is working properly since it seems the mediaproxy chain (lowercase) sends all UDP packets through the MEDIAPROXY (uppercase) chain, which apparently didn't get created. How can I check to make sure that indeed RTPengine is relaying the streams properly? Thanks Here's what my iptables looks like after running modprobe xt_MEDIAPROXY and iptables -I INPUT -p udp -j MEDIAPROXY --id 0 *ncoming packets (INPUT) - Only applies to packets addressed to this host* Select all. <https://securvoice.eu:9998/firewall/index.cgi?table=0#> | Invert selection. <https://securvoice.eu:9998/firewall/index.cgi?table=0#> * <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Action <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Condition <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Move <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Add <https://securvoice.eu:9998/firewall/index.cgi?table=0#>*Jump to chain MEDIAPROXY <https://securvoice.eu:9998/firewall/edit_rule.cgi?table=0&idx=0>If protocol is *UDP* <https://securvoice.eu:9998/firewall/edit_rule.cgi?table=0&chain=INPUT&new=1…> <https://securvoice.eu:9998/firewall/edit_rule.cgi?table=0&chain=INPUT&new=1…>Select all. <https://securvoice.eu:9998/firewall/index.cgi?table=0#> | Invert selection. <https://securvoice.eu:9998/firewall/index.cgi?table=0#> Accept Drop Userspace Exit chain ------------------------------ *Forwarded packets (FORWARD) - Only applies to packets passed through this host* *There are no rules defined for this chain.* Accept Drop Userspace Exit chain ------------------------------ *Outgoing packets (OUTPUT) - Only applies to packets originated by this host* *There are no rules defined for this chain.* Accept Drop Userspace Exit chain ------------------------------ *Chain mediaproxy* Select all. <https://securvoice.eu:9998/firewall/index.cgi?table=0#> | Invert selection. <https://securvoice.eu:9998/firewall/index.cgi?table=0#> * <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Action <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Condition <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Move <https://securvoice.eu:9998/firewall/index.cgi?table=0#>**Add <https://securvoice.eu:9998/firewall/index.cgi?table=0#>*Jump to chain MEDIAPROXY <https://securvoice.eu:9998/firewall/edit_rule.cgi?table=0&idx=1>If protocol is *UDP*

Re: [sr-dev] accessing database from a child forked proces
by Luis Azedo 08 Sep '14

Hi Jason, thanks for the reply. the last 2 statements in presence module mod_init close the connection and set pa_db to NULL. when my module main process forks the extra processes the pa_db in presence is NULL, so when it calls pres_refresh_watchers it fails because pa_db is NULL. i commented these last statements in presence mod_init and i got it to work. // pa_dbf.close(pa_db); // pa_db = NULL; does this have any implications on how the module works ? is it ok to merge this change ?

pres_refresh_watchers
by Luis Azedo 08 Sep '14

08 Sep '14

Hi Daniel, the issue that i'm having with calling pres_refresh_watchers (invalid connection when it calls get_p_notify_body) from a forked process from my module disappears if i comment the lines 411 e 412 in presence.c 411 // pa_dbf.close(pa_db); 412 // pa_db = NULL; i can achieve the desired result if i leave these lines intact and add these lines to pres_refresh_watchers if(pa_db == NULL && library_mode == 0) { pa_db = pa_dbf.init(&db_url); } the first change is more global and will keep me from adding the same lines in (2) to other functions like update_watchers_status. i would like to see either of these changes merged in master and ready for 4.2. with these changes and the db_text that i submitted earlier, i can then ask to merge the main module db_kazoo into master.

Hi, in presence module subscribe.c send_fast_notify is not always honored. by changing this line i got it working. does this make sense ? thanks diff --git a/modules/presence/subscribe.c b/modules/presence/subscribe.c index 3074ca9..f5dd6aa 100644 --- a/modules/presence/subscribe.c +++ b/modules/presence/subscribe.c @@ -682,7 +682,7 @@ } else { - if(notify(subs, NULL, NULL, 0)< 0) + if(send_fast_notify && (notify(subs, NULL, NULL, 0 )< 0)) { LM_ERR("Could not send notify\n"); goto error;
