Hi, I had the time to test one of your nightly builds (namely 48869 gcc2
hybrid); what I noticed is that the issue is not related to websockets
(they work fine) but to the Arguments object.
The arguments object can be obtained in two ways, one is deprecated[1],
the other is not[2]. While I do not expect to find the deprecated form, I
expect that if it is indeed available it should also be usable.
I attach a tiny test case for the issue:
{{{
function foo() {
bar(arguments); //expects [object Arguments] prints [object Arguments]
bar(arguments[0]) ///expects 1 prints 1
bar(foo.arguments); //expects [object Arguments] prints [object
Arguments]
bar(foo.arguments[0]) //expects 1 prints undefined
}
function bar(args) {
console.log(args)
}
foo(1,2,3);
}}}
HTH
