Author: pd <[email protected]> Committer: pd <[email protected]> Date: Thu Dec 8 22:01:06 2011 +0000 modules_k/presence, modules_k/pua, modules_k/rls: Changed rls_update_subs() to not send unnecessary back-end re-SUBSCRIBEs. - The initial implementation sent a re-SUBSCRIBE for each existing back-end dialog and create new back-end dialogs as required (depending on the contents of the updated resource-list) documents. - This was very wasteful, so this version only sends the new SUBSCRIBEs --- modules_k/presence/subscribe.h | 4 ++++ modules_k/pua/send_subscribe.c | 14 ++++++++++++++ modules_k/pua/send_subscribe.h | 1 + modules_k/rls/subscribe.c | 4 ++++ 4 files changed, 23 insertions(+), 0 deletions(-) diff --git a/modules_k/presence/subscribe.h b/modules_k/presence/subscribe.h index 3e318a1..b216fff 100644 --- a/modules_k/presence/subscribe.h +++ b/modules_k/presence/subscribe.h @@ -47,6 +47,9 @@ struct pres_ev; #define TERMINATED_STATUS 3 #define WAITING_STATUS 4 +#define INTERNAL_UPDATE_FALSE 0 +#define INTERNAL_UPDATE_TRUE 1 + struct subscription { str pres_uri; @@ -72,6 +75,7 @@ struct subscription int send_on_cback; int db_flag; str* auth_rules_doc; + int internal_update_flag; struct subscription* next; }; diff --git a/modules_k/pua/send_subscribe.c b/modules_k/pua/send_subscribe.c index 1116896..1406ee4 100644 --- a/modules_k/pua/send_subscribe.c +++ b/modules_k/pua/send_subscribe.c @@ -47,6 +47,7 @@ #include "pua_callback.h" #include "event_list.h" #include "pua_db.h" +#include "../presence/subscribe.h" void print_subs(subs_info_t* subs) @@ -1116,6 +1117,19 @@ insert: */ dlg_t* td= NULL; + + if (subs->internal_update_flag == INTERNAL_UPDATE_TRUE) + { + LM_INFO("attempting to re-SUBSCRIBE on internal (rls_update_subs()) update - skipping\n"); + goto done; + } + + if (presentity->to_tag.len == 0) + { + LM_WARN("attempting to re-SUBSCRIBE to temporary (non-established) dialog - skipping\n"); + goto done; + } + td= pua_build_dlg_t(presentity); if(td== NULL) { diff --git a/modules_k/pua/send_subscribe.h b/modules_k/pua/send_subscribe.h index a6ff737..cddb33a 100644 --- a/modules_k/pua/send_subscribe.h +++ b/modules_k/pua/send_subscribe.h @@ -49,6 +49,7 @@ typedef struct subs_info for the received reply; it must be allocated in share memory; a reference to it will be found in the cb_param filed of the ua_pres_structure receied as a parameter for the registered function*/ + int internal_update_flag; }subs_info_t; diff --git a/modules_k/rls/subscribe.c b/modules_k/rls/subscribe.c index cab70ff..5238804 100644 --- a/modules_k/rls/subscribe.c +++ b/modules_k/rls/subscribe.c @@ -902,6 +902,8 @@ int resource_subscriptions(subs_t* subs, xmlNodePtr xmlnode) extra_headers.len = strlen(extra_headers.s); s.extra_headers = &extra_headers; + + s.internal_update_flag = subs->internal_update_flag; if(process_list_and_exec(xmlnode, subs->from_user, subs->from_domain, send_resource_subs, (void*)(&s))<0) @@ -964,6 +966,8 @@ void update_a_sub(subs_t *subs_copy ) goto done; } + subs_copy->internal_update_flag = INTERNAL_UPDATE_TRUE; + if(resource_subscriptions(subs_copy, service_node)< 0) { LM_ERR("failed sending subscribe requests to resources in list\n"); _______________________________________________ sr-dev mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
