Migrating to v25

Changes needed to migrate to SpiderMonkey v25 from v23

Misc Changes

Compiler update

SpiderMonkey uses static_assert in some header files. So projects that use SpiderMonkey like JS Bindings needs to update its compiler to a C++11 compiler.

API Changes

JS_Init

JS_Init() needs to be called at the very beginning.

JS_SetProperty / JS_GetProperty

JS_SetProperty and JS_GetProperty no longer work with jsval objects. Instead now receives JS::RootedValue objects.

// Old Way
jsval someJSval = OBJECT_TO_JSVAL(someObject);
JS_SetProperty(cx, object, "cp", &someJSval);
JS_GetProperty(cx, object, "cp", &someJSval);

// New Way
JS::RootedValue someJSval(_cx);
someJSval = OBJECT_TO_JSVAL(someObject);
JS_SetProperty(cx, object, "cp", someJSval);
JS_GetProperty(cx, object, "cp", &someJSval);

JS_NewGlobalObject

// Old Way
JS_NewGlobalObject(cx, &global_class, NULL);

// New Way
JS_NewGlobalObject(cx, &global_class, NULL, JS::DontFireOnNewGlobalHook /* or JS::FireOnNewGlobalHook */);

JS_SetVersion

// Old Way
JS_SetVersion(_cx, JSVERSION_LATEST);

// New Way
JS_SetVersionForCompartment(js::GetContextCompartment(_cx), JSVERSION_LATEST);
