Author: Andrei Pelinescu-Onciul <[email protected]> Committer: Andrei Pelinescu-Onciul <[email protected]> Date: Fri Jun 18 22:22:59 2010 +0200 core: fix selects in optimized rvalue expressions - do not attempt to resolve_select() twice the same select. This happened when a rve containing only a select was optimized, the select moved out of the rve and fix_expr() tried to "fix" the already resolved select later. - changed BUG() messages for failed resolve_select() into ERR(). --- route.c | 20 ++++++++++++++------ route_struct.h | 5 +++-- rvalue.c | 2 +- 3 files changed, 18 insertions(+), 9 deletions(-) diff --git a/route.c b/route.c index 9a8f649..0e07556 100644 --- a/route.c +++ b/route.c @@ -588,7 +588,9 @@ int fix_expr(struct expr* exp) exp->r.re=re; exp->r_type=RE_ST; }else if (exp->r_type!=RE_ST && exp->r_type != AVP_ST - && exp->r_type != SELECT_ST && exp->r_type!= RVE_ST + && exp->r_type != SELECT_ST && + exp->r_type != SELECT_UNFIXED_ST && + exp->r_type!= RVE_ST && exp->r_type != PVAR_ST){ LOG(L_CRIT, "BUG: fix_expr : invalid type for match\n"); return E_BUG; @@ -601,19 +603,21 @@ int fix_expr(struct expr* exp) return ret; } } - if (exp->l_type==SELECT_O) { + if (exp->l_type==SELECT_UNFIXED_O) { if ((ret=resolve_select(exp->l.select)) < 0) { - BUG("Unable to resolve select\n"); + ERR("Unable to resolve select\n"); print_select(exp->l.select); return ret; } + exp->l_type=SELECT_O; } - if ((exp->r_type==SELECT_O)||(exp->r_type==SELECT_ST)) { + if (exp->r_type==SELECT_UNFIXED_ST) { if ((ret=resolve_select(exp->r.select)) < 0) { - BUG("Unable to resolve select\n"); - print_select(exp->l.select); + ERR("Unable to resolve select\n"); + print_select(exp->r.select); return ret; } + exp->r_type=SELECT_ST; } /* PVAR don't need fixing */ ret=0; @@ -1895,6 +1899,10 @@ inline static int eval_elem(struct run_act_ctx* h, struct expr* e, case PVAR_O: ret=comp_pvar(e->op, e->l.param, e->r_type, &e->r, msg, h); break; + + case SELECT_UNFIXED_O: + BUG("unexpected unfixed select operand %d\n", e->l_type); + break; /* default: LOG(L_CRIT, "BUG: eval_elem: invalid operand %d\n", diff --git a/route_struct.h b/route_struct.h index 4894bd5..3f7e854 100644 --- a/route_struct.h +++ b/route_struct.h @@ -76,7 +76,7 @@ enum _expr_l_type{ METHOD_O=51, URI_O, FROM_URI_O, TO_URI_O, SRCIP_O, SRCPORT_O, DSTIP_O, DSTPORT_O, PROTO_O, AF_O, MSGLEN_O, ACTION_O, NUMBER_O, AVP_O, SNDIP_O, SNDPORT_O, TOIP_O, TOPORT_O, SNDPROTO_O, - SNDAF_O, RETCODE_O, SELECT_O, PVAR_O, RVEXP_O}; + SNDAF_O, RETCODE_O, SELECT_O, PVAR_O, RVEXP_O, SELECT_UNFIXED_O}; /* action types */ enum action_type{ FORWARD_T=1, SEND_T, DROP_T, LOG_T, ERROR_T, ROUTE_T, EXEC_T, @@ -121,7 +121,8 @@ enum _operand_subtype{ SELECT_ST, PVAR_ST, LVAL_ST, RVE_ST, RETCODE_ST, CASE_ST, - BLOCK_ST, JUMPTABLE_ST, CONDTABLE_ST, MATCH_CONDTABLE_ST + BLOCK_ST, JUMPTABLE_ST, CONDTABLE_ST, MATCH_CONDTABLE_ST, + SELECT_UNFIXED_ST }; typedef enum _expr_l_type expr_l_type; diff --git a/rvalue.c b/rvalue.c index 38a0eb7..9b3faca 100644 --- a/rvalue.c +++ b/rvalue.c @@ -2768,7 +2768,7 @@ static int fix_rval(struct rvalue* rv) return fix_actions(rv->v.action); case RV_SEL: if (resolve_select(&rv->v.sel)<0){ - BUG("Unable to resolve select\n"); + ERR("Unable to resolve select\n"); print_select(&rv->v.sel); } return 0; _______________________________________________ sr-dev mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
