Handle to Persistent for ClearWeak

[Andrey]

Hello, All.

Why in this code sample does not work IsWeak and ClearWeak?

void WeakCallback( v8::Persistent<v8::Value> object, void* parameter)

{

   int* obj = static_cast< int* >( parameter );

   delete obj;

   object.ClearWeak();

   object.Dispose();

}

v8::Handle<v8::Object> obj()

{

   HandleScope hs;

   v8::Local<v8::Object> obj = v8::Object::New();

   

   //I want that my object has a reference to native pointer

   v8::Local<v8::ObjectTemplate> native_tmpl = v8::ObjectTemplate::New();

   native_tmpl->SetInternalFieldCount( 1 );

   v8::Persistent<v8::Object> native = v8::Persistent<v8::Object>::New( native_tmpl->NewInstance() );

   int* ptr_i = new int( 1 );

   native->SetPointerInInternalField( 0, ptr_i );

   native.MakeWeak( ptr_i, WeakCallback );

   obj->Set( v8::String::New( "native" ), native );

   return hs.Close( obj );

}

//code

v8::Handle<v8::Value> native = obj()->Get( v8::String::New( "native" ) );

v8::Persistent<v8::Object> persistent = v8::Persistent<v8::Object>( native->ToObject() );

bool b = persistent.IsWeak();//return false

persistent.ClearWeak();//doesn't work, because WeakCallback has been called by gc

ClearWeak is necessary not to cause WeakCallback after std::move for native C++ pointer.

What am I doing wrong?
