I am using WebKit based browser with JSC, and would like to add a new event
like onStateChanged using DEFINE_ATTRIBUTE_EVENT_LISTENER() macro.
Sometimes an event was dispatched correctly and it reached to JS
but sometimes not dispatched caused by JSEventListener::jsFunction()
returns 0 (at JSEventListener::handleEvent()).
The verification failed in JSEventListener::jsFunction().
At that, there is a comment as :
// Verify that we have a valid wrapper protecting our function from
// garbage collection.
Then I have a few questions as below.
1. How to block garbage collection to free m_wrapper ?
GCController seems to just collect heap without any conditions.
2. Is it possible to recover/recreate m_wrapper as like as
Please help me.
