Author: Anca Vamanu <[email protected]> Committer: Anca Vamanu <[email protected]> Date: Wed May 2 18:42:55 2012 +0300 modules_k/presence Fixed wrong cseq and wrong expires bugs 1. Wrong cseq bug: happened in subs_db_mode!= DB_ONLY when generating Notify with expires=0 that was not triggered by a received Subscribe 2. Problem with expires raported in Notify message. There was a static buffer used twice when building the extra headers for Notify leading to expires parameter value always having last digits '70' (the value of Max-Forwards). --- modules_k/presence/notify.c | 116 ++++++++++++++-------------------------- modules_k/presence/presence.c | 4 +- modules_k/presence/subscribe.c | 2 + 3 files changed, 45 insertions(+), 77 deletions(-) diff --git a/modules_k/presence/notify.c b/modules_k/presence/notify.c index 4f8d68b..f778511 100644 --- a/modules_k/presence/notify.c +++ b/modules_k/presence/notify.c @@ -134,18 +134,17 @@ int build_str_hdr(subs_t* subs, int is_body, str* hdr) pres_ev_t* event= subs->event;
