Bug 94533 – [JSC] expose object inner properties to debugger

• Status: NEW
• Component: JavaScriptCore

[Peter Rybin]

In JavaScript several objects have hidden properties, namely: Boolean, Number and String have "[[PrimitiveValue]]" and bound function has "[[BoundThis]]", "[[TargetFunction]]" and "[[BoundArgs]]". While the language doesn't provide any explicit access to this properties, debugger should expose it as it might be a valuable piece of data.
In debug API there should be a way to access this inner context.

[Peter Rybin]

Date object also has primitive value, but its type is unspecified and that's why this bug doesn't require it.

Wrong, this is the [JSC] version of that bug. Note the FIXME in the patch attached to the bug you linked:

JSValue JSInjectedScriptHost::getInternalProperties(ExecState*) 
{ 
    // FIXME: implement this. https://bugs.webkit.org/show_bug.cgi?id=94533 
    return jsUndefined(); 
}

Thanks a lot Timothy. I completely overlooked [JSC] marker and I took it for the real obsolete bug I used to have about it.
