Module: kamailio Branch: master Commit: f69c13a587df53fb93999d81cd02dc99ab223187 URL: https://github.com/kamailio/kamailio/commit/f69c13a587df53fb93999d81cd02dc9… Author: Daniel-Constantin Mierla <miconda(a)gmail.com> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: 2022-08-30T10:53:15+02:00 tm: added t_unset() intermodule API function - reset global t and branch without releasing the transaction - useful for cases when global t needs to be set in callbacks and then reset before config execution is finished --- Modified: src/modules/tm/t_lookup.c Modified: src/modules/tm/t_lookup.h Modified: src/modules/tm/tm_load.c Modified: src/modules/tm/tm_load.h --- Diff: https://github.com/kamailio/kamailio/commit/f69c13a587df53fb93999d81cd02dc9… Patch: https://github.com/kamailio/kamailio/commit/f69c13a587df53fb93999d81cd02dc9… --- diff --git a/src/modules/tm/t_lookup.c b/src/modules/tm/t_lookup.c index ad41f0de93..dd2ed6f0ae 100644 --- a/src/modules/tm/t_lookup.c +++ b/src/modules/tm/t_lookup.c @@ -167,6 +167,19 @@ struct cell* t_find(struct sip_msg *msg, int *branch, int *vref) return T; } +/** + * unref and reset T globals + */ +void t_unset(void) +{ + if(T == NULL || T == T_UNDEFINED) { + return; + } + + UNREF( T ); + set_t(T_UNDEFINED, T_BR_UNDEFINED); +} + static inline int parse_dlg( struct sip_msg *msg ) { if (parse_headers(msg, HDR_FROM_F | HDR_CSEQ_F | HDR_TO_F, 0)==-1) { diff --git a/src/modules/tm/t_lookup.h b/src/modules/tm/t_lookup.h index de65be8365..c4b5404cf8 100644 --- a/src/modules/tm/t_lookup.h +++ b/src/modules/tm/t_lookup.h @@ -71,6 +71,9 @@ struct cell *get_t(void); typedef struct cell* (*tfind_f)(struct sip_msg*, int*, int*); struct cell* t_find(struct sip_msg *msg, int *branch, int *vref); +typedef void (*tunset_f)(void); +void t_unset(void); + typedef int (*tgett_branch_f)(void); int get_t_branch(void); diff --git a/src/modules/tm/tm_load.c b/src/modules/tm/tm_load.c index c9f39b576e..d5fc6e7884 100644 --- a/src/modules/tm/tm_load.c +++ b/src/modules/tm/tm_load.c @@ -93,6 +93,7 @@ int load_tm( struct tm_binds *tmb) tmb->print_dlg = print_dlg; tmb->t_gett = get_t; tmb->t_find = t_find; + tmb->t_unset = t_unset; tmb->t_gett_branch = get_t_branch; tmb->t_sett = set_t; tmb->calculate_hooks = w_calculate_hooks; diff --git a/src/modules/tm/tm_load.h b/src/modules/tm/tm_load.h index 1f97061d1e..130d01503a 100644 --- a/src/modules/tm/tm_load.h +++ b/src/modules/tm/tm_load.h @@ -72,6 +72,7 @@ struct tm_binds { print_dlg_f print_dlg; tgett_f t_gett; tfind_f t_find; + tunset_f t_unset; tgett_branch_f t_gett_branch; tsett_f t_sett; calculate_hooks_f calculate_hooks;
