Hello, after a lot of trouble with misterious errors "HTTP Error 500: Internal Server Error" and "HTTP Error 502: Bad Gateway", I've uploaded my repository.
https://bitbucket.org/schlegea/mozilla-central-js-tproxy-fork The name of the repository is bad choosen, it's not a fork, only a copy for experimental research. My work for the moment: * Implement a new trap "isTransparent" for distinguish between transparent and opaque Proxies (transparent proxies in comparisms are compared by it's targets) * Implement a method which gives either the target (case is a transparent proxy) or the given object back * Use the method for compare Objects in LooselyEqual and StrictlyEqual of Interpreter.cpp * Manipulate WeakMap with new hash structure: o if Key is a transparent proxy + first inserted object builds the key element (behaviour like implemented) + target of transparent proxy is hashed + if a new transparent proxy for the target is inserted only the value is updated not the key o if key is an opaque proxy + no changes for the behaviour * Manipulate Map/Set hash structure: o if Key is a transparent proxy + last inserted object builds the key element (behaviour like implemented) + target of transparent proxy is hashed + if a new transparent proxy for the target is inserted the complete element is updated o if key is an opaque proxy + no changes for the behaviour The tests for JSTest are in "js/src/tests/ecma_6/Proxy". The tests for the JIT are "js/src/jit-test/tests/basic/testComparisons.js" and "js/src/jit-test/tests/basic/testComparisons_loop.js". ---------- I'm working at the moment at the problem, that if I have a global with a transparent proxy, this proxy needs also the implementation of the CrossCompartmentWrapper. But I have problems to get the implementation to work. I've tried to implement the same trap like the trap for the ScrptedProxyHandler for the DirektProxyHandler and use Wrapper::isTransparent() in the isTransparent()-method of the CrossCompartmentWrapper: bool CrossCompartmentWrapper::isTransparent(JSContext *cx, HandleObject wrapper, bool *bp) { return Wrapper::isTransparent(cx, wrapper, bp); } I use the following function GetDirectProxyHandlerObject to get the Handler Object like in the ScriptedProxyHandler, but in this case I get an assertion in the function "toObjectOrNull()": Assertion failure: isObjectOrNull(), at ../dist/include/js/Value.h:1157 static JSObject * GetDirectProxyHandlerObject(JSObject *proxy) { return proxy->as<ProxyObject>().extra(0).toObjectOrNull(); } bool DirectProxyHandler::isTransparent(JSContext *cx, HandleObject proxy, bool *bp) { // step 1 RootedObject handler(cx, GetDirectProxyHandlerObject(proxy)); // step 2 JSString* propStr = JS_InternString(cx, "isTransparent"); JSAtom& atom = propStr->asAtom(); RootedValue trap(cx); if (!JSObject::getProperty(cx, handler, handler, atom.asPropertyName(), &trap)) return false; // step 3 if (trap.isUndefined()) { *bp = false; return true; } // step 4 Value argv[] = { // ObjectOrNullValue(target), // value }; RootedValue trapResult(cx); if (!Invoke(cx, ObjectValue(*handler), trap, 0, argv, &trapResult)) return false; // step 5 bool success = ToBoolean(trapResult); // step 6 *bp = success; return true; } How can I retrieve the proxy handler to get the data from the trap?
