[IDAScript] Label Databases

[kynox]

Some more IDA script from me!

In this installment of label-that-feature, we focus on databases to easily identify when functions are accessing database information.

Example of productivity enhancement:

signed int __cdecl lua_GetItemIcon(int a1)
{
  int v1; // esi@1
  int v2; // eax@2
  char *v3; // eax@4
  DWORD v4; // esi@8
  char *v5; // ebx@9
  char v6; // zf@9
  signed int result; // eax@11
  int v8; // eax@11
  char icon[260]; // [sp+8h] [bp-108h]@11
  char *v10; // [sp+10Ch] [bp-4h]@9

  v1 = 0;
  if ( lua_isnumber(a1) )
  {
    v2 = lua_tointeger(a1, 1);
LABEL_5:
    v1 = v2;
    goto LABEL_6;
  }
  if ( lua_isstring(a1, 1) )
  {
    v3 = lua_tostring(a1, 1, 0);
    v2 = GetItemIDByName(v3);
    goto LABEL_5;
  }
LABEL_6:
  if ( v1 >= g_ItemDB.minIndex && v1 <= g_ItemDB.maxIndex && (v4 = g_ItemDB.Rows[v1 - g_ItemDB.minIndex]) != 0 )
  {
    v5 = ClientDBStringLookup(3);
    v6 = *v5 == 0;
    v10 = "\\";
    if ( v6 )
      v10 = nullString;
    v8 = CGItem_C__GetInventoryArt(*(_DWORD *)(v4 + 20));
    SStrPrintf(icon, 260u, "%s%s%s", v5, v10, v8);
    lua_pushstring(a1, icon);
    result = 1;
  }
  else
  {
    result = 0;
  }
  return result;
}

Note: This was written around IDA 5.5, if you have an inferior version; manually insert the struct as follows:

#pragma pack(push, 1)
struct WoWClientDB
{
  void *funcTable;
  int isLoaded;
  int numRows;
  int maxIndex;
  int minIndex;
  int stringTable;
  void *funcTable2;
  DWORD FirstRow;
  DWORD *Rows;
};
#pragma pack(pop)

<3 you.
Thats just awesome.

Works fine with IDA 5.2 with small modifications. Thank you.
