About ProtoProps (stackTraceLimit and prepareStackTrace) of NativeError

[SuperMonster003]

Is there documentation about how to use stackTraceLimit and prepareStackTrace for a NativeError instance?

I tried the following code but nothing printed in console:

Error.prepareStackTrace = function () {
    console.log(arguments);
    return "test";
};
try {
    (0).toFixed(-1);
} catch (e) {
    // Ignored.
}

Also, code like Error.stackTraceLimit = 5; seems invalid.

BTW, i found some code may have some relations.

rhino/src/org/mozilla/javascript/NativeError.java

Line 81 in 4eeea69

associateValue(ProtoProps.KEY, protoProps);

rhino/src/org/mozilla/javascript/NativeError.java

Lines 182 to 183 in 4eeea69

	NativeError cons = (NativeError) getPrototype();
	ProtoProps pp = (ProtoProps) cons.getAssociatedValue(ProtoProps.KEY);

What makes me confused is that L183 always got a null result (for variable "pp").

There's no specific Rhino documentation, as it should function the same as in v8/node.

You could have a look at our testcases for these option: https://github.com/mozilla/rhino/blob/1b7e8ab9f18011756e0298812497b16c41006ff7/testsrc/jstests/extensions/stack-traces-v8.js
