git:master: New global variable route_type with the type of route being executed

This value of the variable is one of the *_ROUTE values defined in route.h. … [View More]Those defines have been moved from sr_module.h, originally they were used as the flags for functions in module exports but we can use them here for the global route_type variable as well. The variable route_type is meant to be used by module functions, in some cases they need to test for the type of the route being executed to know what functions are available and whether the sip message being process is stored in shared memory or private memory. The tm module contained similar variable (which was exported through the tm module API), but it makes more sense to keep it in sip-router core, because the core can execute two route types, the request route and the onreply route, even if the tm module is not used. --- route.h | 23 +++++++++++++++++++++++ sr_module.h | 10 +--------- 2 files changed, 24 insertions(+), 9 deletions(-) diff --git a/route.h b/route.h index 732d4a9..221fb4c 100644 --- a/route.h +++ b/route.h @@ -42,6 +42,29 @@ /*#include "cfg_parser.h" */ +/* Various types of route sections, make sure that the values defined in the + * macros below occupy disjunct bits so that they can also be used as flags + */ +#define REQUEST_ROUTE (1 << 0) +#define FAILURE_ROUTE (1 << 1) +#define ONREPLY_ROUTE (1 << 2) +#define BRANCH_ROUTE (1 << 3) +#define ONSEND_ROUTE (1 << 4) +#define ERROR_ROUTE (1 << 5) +#define LOCAL_ROUTE (1 << 6) + +/* The value of this variable is one of the route types defined above and it + * determines the type of the route being executed, module functions can use + * this value to determine the type of the route they are being executed in + */ +extern int route_type; + +#define set_route_type(type) \ + do { \ + route_type = (type); \ + } while(0) + +#define is_route_type(type) (route_type == (type)) struct route_list{ struct action** rlist; diff --git a/sr_module.h b/sr_module.h index 149ca6e..0078f25 100644 --- a/sr_module.h +++ b/sr_module.h @@ -62,6 +62,7 @@ #include "version.h" #include "rpc.h" #include "route_struct.h" +#include "route.h" #include "str.h" /* kamailio compat */ @@ -146,15 +147,6 @@ typedef int (*param_func_t)( modparam_t type, void* val); #define VAR_PARAM_NO -128 /* function has variable number of parameters (see cmd_function_var for the prototype) */ -/* functions flags */ -#define REQUEST_ROUTE 1 /* Function can be used in request route blocks */ -#define FAILURE_ROUTE 2 /* Function can be used in reply route blocks */ -#define ONREPLY_ROUTE 4 /* Function can be used in on_reply */ -#define BRANCH_ROUTE 8 /* Function can be used in branch_route blocks */ -#define ONSEND_ROUTE 16 /* Function can be used in onsend_route blocks */ -#define ERROR_ROUTE 32 /* Function can be used in an error route */ -#define LOCAL_ROUTE 64 /* Function can be used in a local route */ - /* Macros - used as rank in child_init function */ #define PROC_MAIN 0 /* Main ser process */ #define PROC_TIMER -1 /* Timer attendant process */ [View Less]
