It stopped working after default became a keyword (switch()). - fix: allow negative number in selects (e.g. @eval.pop[-1]) - fix: allow negative number in function parameters - fix setavpflag, resetavpflag, isavpflag and "simple" avp names --- cfg.y | 49 ++++++++++++++++++++++++++++++++++++++----------- 1 files changed, 38 insertions(+), 11 deletions(-) diff --git a/cfg.y b/cfg.y index 49608a2..a0b13d6 100644 --- a/cfg.y +++ b/cfg.y @@ -561,6 +561,7 @@ static int case_check_default(struct case_stms* stms); %type <strval> route_name; %type <intval> avpflag_oper %type <intval> rve_un_op +%type <strval> cfg_var_id /* %type <intval> rve_op */ /*%type <route_el> rules; @@ -1361,29 +1362,37 @@ assign_stm: | cfg_var | error EQUAL { yyerror("unknown config variable"); } ; + +cfg_var_id: ID + | DEFAULT { $$="default" ; } /*needed to allow default as cfg var. name*/ + ; + cfg_var: - ID DOT ID EQUAL NUMBER { + cfg_var_id DOT cfg_var_id EQUAL NUMBER { if (cfg_declare_int($1, $3, $5, 0, 0, NULL)) { yyerror("variable cannot be declared"); } } - | ID DOT ID EQUAL STRING { + | cfg_var_id DOT cfg_var_id EQUAL STRING { if (cfg_declare_str($1, $3, $5, NULL)) { yyerror("variable cannot be declared"); } } - | ID DOT ID EQUAL NUMBER CFG_DESCRIPTION STRING { + | cfg_var_id DOT cfg_var_id EQUAL NUMBER CFG_DESCRIPTION STRING { if (cfg_declare_int($1, $3, $5, 0, 0, $7)) { yyerror("variable cannot be declared"); } } - | ID DOT ID EQUAL STRING CFG_DESCRIPTION STRING { + | cfg_var_id DOT cfg_var_id EQUAL STRING CFG_DESCRIPTION STRING { if (cfg_declare_str($1, $3, $5, $7)) { yyerror("variable cannot be declared"); } } - | ID DOT ID EQUAL error { yyerror("number or string expected"); } + | cfg_var_id DOT cfg_var_id EQUAL error { + yyerror("number or string expected"); + } ; + module_stm: LOADMODULE STRING { DBG("loading module %s\n", $2); @@ -2010,7 +2019,7 @@ select_param: sel.params[sel.n].v.s.len = strlen($1); sel.n++; } - | ID LBRACK NUMBER RBRACK { + | ID LBRACK intno RBRACK { if (sel.n >= MAX_SELECT_PARAMS-2) { yyerror("Select identifier too long\n"); } @@ -2071,8 +2080,8 @@ attr_spec: attr_mark: ATTR_MARK { s_attr = (struct avp_spec*)pkg_malloc(sizeof(struct avp_spec)); - if (!s_attr) { yyerror("No memory left"); } - s_attr->type = 0; + if (!s_attr) { yyerror("No memory left"); YYABORT; } + else s_attr->type = 0; } ; attr_id: @@ -2108,6 +2117,17 @@ attr_id_any: ; attr_id_any_str: attr_id + | avp_pvar { + if ($1->type==LV_AVP){ + s_attr = pkg_malloc(sizeof(struct avp_spec)); + if (!s_attr) { yyerror("No memory left"); YYABORT; } + else{ + *s_attr=$1->lv.avps; + } + }else + $$=0; /* not an avp, a pvar */ + pkg_free($1); + } | STRING { avp_spec_t *avp_spec; str s; @@ -2266,8 +2286,8 @@ rve_op: PLUS { $$=RVE_PLUS_OP; } rval_expr: rval { $$=$1; if ($$==0){ - yyerror("out of memory\n"); - YYABORT; + /*yyerror("out of memory\n");*/ + YYERROR; } } | rve_un_op %prec NOT rval_expr {$$=mk_rve1($1, $2); } @@ -2589,6 +2609,13 @@ cmd: if (i_tmp==0) yyerror("avpflag not declared"); $$=mk_action(AVPFLAG_OPER_T, 3, AVP_ST, $3, NUMBER_ST, (void*)(long)i_tmp, NUMBER_ST, (void*)$1); } + | avpflag_oper LPAREN attr_id_any_str COMMA error RPAREN { + $$=0; yyerror("error parsing flag name"); + } + | avpflag_oper LPAREN error COMMA flag_name RPAREN { + $$=0; yyerror("error parsing first parameter (avp or string)"); + } + | avpflag_oper LPAREN error RPAREN { $$=0; yyerror("bad parameters"); } | avpflag_oper error { $$=0; yyerror("missing '(' or ')'?"); } | ERROR LPAREN STRING COMMA STRING RPAREN {$$=mk_action(ERROR_T, 2, STRING_ST, $3, STRING_ST, $5); } | ERROR error { $$=0; yyerror("missing '(' or ')' ?"); } @@ -2765,7 +2792,7 @@ func_params: | func_params error { yyerror("call params error\n"); } ; func_param: - NUMBER { + intno { if (mod_func_action->val[1].u.number < MAX_ACTIONS-2) { mod_func_action->val[mod_func_action->val[1].u.number+2].type = NUMBER_ST;
