Bug 131186 – Web Inspector: JSContext inspection provide a way to opt-out of including Native Call Stacks in Exception traces reported to Web Inspector

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

By default JSContext Inspection includes the native call stack above the JSC API boundary when there is a JavaScript exception in the context.

For example:

    @implementation Foo
    - (void)bar {
        JSContext *context = [[JSContext alloc] init];
        [context evaluateScript:@"var a=;"]; // Throws an exception.
    }
    @end

A JSContext inspector will see the JS exception stack "(anonymous function)" and the "-[JSContext evaluateScript], -[Foo bar], ..." call frames.

Some clients, may not want that. Provide SPI to turn off this behavior, so that only the JS exception stack will be visible.

I think the preferred terminology when it comes to verbs is the infinitive: "setIncludes" instead of "setInclude".
