Module: kamailio Branch: master Commit: 0def328282cb8551823554978d7e32afa7ca4110 URL: https://github.com/kamailio/kamailio/commit/0def328282cb8551823554978d7e32a… Author: Stefan Mititelu &lt;stefan.mititelu(a)1and1.ro&gt; Committer: Stefan Mititelu &lt;stefan.mititelu(a)1and1.ro&gt; Date: 2015-12-10T14:28:59+02:00 rtpengine: Check set uniqueness for rtpp node If node already found in set, update details like weight, recheck_ticks, disabled status. Else, create new node for the specific set. This is especially useful when reloading the nodes from database via 'kamctl fifo nh_rtpp_reload'; just to update the nodes,no shm_free and realloc needed. Also applicable for the config file nodes. This per set uniqueness of the nodes is plausible given the possibility to set the weight of the rtpp nodes. --- Modified: modules/rtpengine/rtpengine.c Modified: modules/rtpengine/rtpengine.h --- Diff: https://github.com/kamailio/kamailio/commit/0def328282cb8551823554978d7e32a… Patch: https://github.com/kamailio/kamailio/commit/0def328282cb8551823554978d7e32a… --- diff --git a/modules/rtpengine/rtpengine.c b/modules/rtpengine/rtpengine.c index 36b09a8..501763b 100644 --- a/modules/rtpengine/rtpengine.c +++ b/modules/rtpengine/rtpengine.c @@ -204,7 +204,7 @@ static char *send_rtpp_command(struct rtpp_node *, bencode_item_t *, int *); static int get_extra_id(struct sip_msg* msg, str *id_str); static int rtpengine_set_store(modparam_t type, void * val); -static int rtpengine_add_rtpengine_set( char * rtp_proxies); +static int rtpengine_add_rtpengine_set(char * rtp_proxies, int disabled, unsigned int ticks); static int mod_init(void); static int child_init(int); @@ -521,6 +521,9 @@ static int bind_force_send_ip(int sock_idx) return 0; } +static inline int str_cmp(const str *a , const str *b) { + return !
