This addresses a current shortcoming of the V8 SetNamedPropertyHandler function. It does not provide a way to intercept Object.defineProperty(..) calls. As a result, these properties are not copied onto the contextified sandbox when a new global property is added via either a function declaration or a Object.defineProperty(global, ...) call. Note that any function declarations or Object.defineProperty() globals that are created asynchronously (in a setTimeout, callback, etc.) will happen AFTER the call to copy properties, and thus not be caught. The way to properly fix this is to add some sort of a Object::SetNamedDefinePropertyHandler() function that takes a callback, which receives the property name and property descriptor as arguments. Luckily, such situations are rare, and asynchronously-added globals weren't supported by Node's VM module until 0.12 anyway. But, this should be fixed properly in V8, and this copy function should be removed once there is a better way. Fix #6416 |
