New issue 4125 by [email protected]: Array.prototype.sort doesn't call
ToObject on receiver
https://code.google.com/p/v8/issues/detail?id=4125
ES6 specifies that ToObject is called on the receiver before the sort
procedure is run
https://people.mozilla.org/~jorendorff/es6-draft.html#sec-array.prototype.sort .
However, look at the difference here:
d8> Number.prototype[0] = 5;
5
d8> Number.prototype[1] = 4;
4
d8> Number.prototype.length = 2;
2
d8> x = new Number(0);
0
d8> Array.prototype.sort.call(x)
0
d8> x[0]
4
d8> x[1]
5
d8> Object.getOwnPropertyNames(x)
["0", "1"]
That was all good. However:
d8> Array.prototype.sort.call(0)
(d8):1: illegal access
Array.prototype.sort.call(0)
This would be really easy to fix. Just put a call to TO_OBJECT in the
beginning of the ArraySort implementation the way all the other functions
in src/arrays.js have.
