In the following test, the explicit check // inside the callback yields different results than deferring the // check until after the callback. The check is deferred if the // callback does not intercept, i.e., if args.GetReturnValue().Set() is // not called. // Check that the GetterCallback explicitly calls GetRealNamedProperty() // on the global proxy if the property is not found on the sandbox. // // foo is not defined on the sandbox until we call CopyProperties(). // In the GetterCallback, we do not find the property on the sandbox and // get the property from the global proxy. Since the return value is // the sandbox, we replace it by // the global_proxy to keep the correct identities. // // This test case is partially inspired by // https://github.com/nodejs/node/issues/855 const sandbox = { console }; sandbox.document = { defaultView: sandbox }; vm.createContext(sandbox); const code = `Object.defineProperty( this, 'foo', { get: function() {return document.defaultView} } ); var result = foo === this;`; vm.runInContext(code, sandbox); assert.strictEqual(sandbox.result, true);
