Sorry for resurrecting this post after such a long time, but I'm having the same (or very similar) problem as MikeM, in trying to add additional javascript objects (which may themselves be the global object of another context) to the prototype chain of the global object of a v8 context. It seems like this should be possible, but I can't find the one way that makes everything work. MikeM, were you able to solve your problem?
Application: my global object has a property interceptor assigned to catch all variable accesses (properties) at global scope and delegate those calls to the embedding application. However, if a variable name doesn't exist in the embedding application, I want to delegate to the prototype chain of the Global object, as usual. At the root of my application, I have a javascript object defined in a js file that I load and compile into JS; This object should be in the prototype chain of every context in the application. I have a series of v8::contexts that correspond to a data model hierarchy in my application, where the global object of a child node context should have the global object of the parent node context as its prototype. I haven't found a reason why this shouldn't be possible, but neither have I gotten it to work. I have tried: Create the ObjectTemplate, create the Context (with the template), get the global object reference (accounting for the proxy global), and SetPrototype(my_parent_object) Create the ObjectTemplate, create the Context (with the template), get the global object reference (accounting for the proxy global), continue to traverse using GetPrototype until GetPrototype returns null, then use SetPrototype(my_parent_object) on that root prototype object. Create a FunctionTemplate to treat as a constructor, write a c++ function (js constructor) that assigns the prototype to the newly-created object, and create the Context with the InstanceTemplate of the FunctionTemplate. All of these techniques (after a fair bit of fiddling) will compile and execute without segfaults, but none successfully configures the prototype chain, since I cannot access the properties of the intended parent class. Is what I am trying to accomplish possible? Is there a better approach?
