Hi,
I am using WebKit JSAPI to create my own JS object, looks like there is memory
leak when calling JSObjectMake()/JSValueUnprotect().
My calling sequence like follow:
{
myJSClass = JSClassCreate(&my_jsclass_def);
myJSObj = JSObjectMake(context, myJSClass, NULL);
JSClassRelease(myJSClass);
...
JSValueUnprotect(context, myJSObj);
}
I looked into WebKit, after JSValueUnprotect was called, while garbage
collector try to delete the object, ref-count of jsClass was not 0 at the time,
so it was not deleted. If I have a big list of property or functions in myJSObj
and frequently create/release the object, it will cause big memory problem.
I traced the reference counter of the object, there are two places to increase
it:
1. creating JSCallbackObjectData
2. creating OpaqueJSClassContextData
While garbage collector deletes the object, the first one got deref but second
one did not.
After I force to deref it, I saw ~OpaqueJSClass() was called. however still
have problem to remove OpaqueJSClassStaticValuesTable
Can any one help to check if I missed some thing from my calling function or if
it is memory leak in the API, any comment how to fit it?
Thanks,
Victor
