42 * SUMMARY: Truncating arrays that have decimal property names.
43 * From correspondence with Igor Bukanov <igor@icesoft.no>:
45 //-----------------------------------------------------------------------------
47 var BUGNUMBER = '(none)';
48 var summary = 'Truncating arrays that have decimal property names';
49 var BIG_INDEX = 4294967290;
53 var actualvalues = [];
55 var expectedvalues = [];
58 var arr = Array(BIG_INDEX);
59 arr[BIG_INDEX - 1] = 'a';
60 arr[BIG_INDEX - 10000] = 'b';
61 arr[BIG_INDEX - 0.5] = 'c'; // not an array index - but a valid property name
62 // Truncate the array -
63 arr.length = BIG_INDEX - 5000;
66 // Enumerate its properties with for..in
75 * We expect s == 'cb' or 'bc' (EcmaScript does not fix the order).
76 * Note 'c' is included: for..in includes ALL enumerable properties,
77 * not just array-index properties. The bug was: Rhino gave s == ''.
