I'm working on a simple application where a few JS functions are cached
during setup and then called repeatedly on a timer. I'm getting a failed
assertion when the cached script is called, and I don't know how to debug
it.
So my C application looks something like this:
static JSContextRef cachedFunctionContext;
static JSObjectRef cachedFunction;
//this callback caches the 'tick' function defined in the setup script
JSValueRef setTickFunctionCallback(JSContextRef ctx, JSObjectRef
function, JSObjectRef thisObject, size_t argumentCount, const JSValueRef
arguments[], JSValueRef *exception){
cachedFunction = arguments[0];
cachedFunctionContext = ctx;
JSValueProtect(ctx, cachedFunction);
return JSValueMakeNull(ctx);
}
//this function runs the setup script
void setup(const char* setupScript){
//setup context and native callbacks
JSEvaluateScript(context, scriptJS, NULL, NULL, 0, NULL);
}
//this function is called on a timer
void tick(){
JSObjectCallAsFunction(cachedFunctionContext, cachedFunction,
NULL, 0, NULL, NULL);
}
And my setup script looks something like this:
var setup = function() {
setTickFunction(function(){
//do something
});
}
setup();
But during execution, I get this assertion failure I don't know how to
interpret:
*ASSERTION FAILED: callFrame->frameExtent() <= oldEnd || callFrame ==
callFrame->scopeChain()->globalObject->globalExec()*
Any insight into what I might be doing wrong would be greatly appreciated.
