Iterating over tp_dict

[Manuel Torrinha]

Hi,

I am trying to implement a function that iterates over the tp_dict structure inside tinypy.

I have implemented similar functions of other object types, including lists without trouble.

However with dicts I often get SEG FAULT while printing a value (not key) element of the dictionary.

I am using the alloc member of the structure as the number of elements present in the items array.

What could I be doing wrong?

Heres my code:

void print_tp_obj(tp_obj v){
  int type = v.type;

  switch(type){
    case TP_DICT:
      print_tp_dict(v);
      break;
  }
}

void print_tp_item(tp_item i){
  /*key*/
  if(strcmp(i.key.string.val, "") == 0)
    return;
  fprintf(stderr,"\"");
  print_tp_string(i.key);
  fflush(stderr);
  fprintf(stderr,"\" : ");
  /*value*/
  fprintf(stderr,"\"");
  print_tp_obj(i.val);
  fflush(stderr);
  fprintf(stderr,"\"");
}

void print_tp_dict(tp_obj v){
  tp_item *items = v.dict.val->items;
  int items_n = v.dict.val->alloc;
  register int i;

  fprintf(stderr,"{\n");
  for(i=0; i < items_n; i++){

    if(items[i].used != 1) {
      continue;
    }

    print_tp_item(items[i]);

    if(i != items_n-1)
      fprintf(stderr,",\n");

  }
  fprintf(stderr,"}\n");
}

Thanks in advance!
