This allows using shm memory early, in modparam fixups or route block parsing functions. user and shm_force_alloc must be used _before_ any modparam or route block (using them after a modparam or a route block will now generate an error). - the user in the cfg is ignored if already set from the command line --- cfg.y | 128 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++------- 1 files changed, 115 insertions(+), 13 deletions(-) diff --git a/cfg.y b/cfg.y index 234b2d0..ac07fc1 100644 --- a/cfg.y +++ b/cfg.y @@ -96,6 +96,7 @@ * 2009-01-26 case/switch() support (andrei) * 2009-03-10 added SET_USERPHONE action (Miklos) * 2009-05-04 switched if to rval_expr (andrei) + * 2010-01-10 init shm on first mod_param or route block (andrei) */ %{ @@ -111,6 +112,9 @@ #include <errno.h> #include "route_struct.h" #include "globals.h" +#ifdef SHM_MEM +#include "shm_init.h" +#endif /* SHM_MEM */ #include "route.h" #include "switch.h" #include "dprint.h" @@ -867,8 +871,20 @@ assign_stm: | MEMSUM EQUAL error { yyerror("int value expected");
