Hi,
Tried to create multiple instance of v8 in my process using isolate.
In Thread A i have the following code. (this is a worker thread and the
following code is called only when there is update in the javascript)
v8::Isolate* isolate2 = v8::Isolate::New();
{
v8::V8::Initialize();
v8::Locker l(isolate2);
v8::Isolate::Scope isolate_scope(isolate2);
v8::HandleScope handle_scope;
....
// script is compiled here
}
In thread B
{
if(v8::Locker::IsActive())
{
std:: cout << "Active" << std::endl;
}
v8::HandleScope handle_scope;
//Context scope
//Run the script
}
I get following error
Fatal error in HandleScope::HandleScope
# Entering the V8 API without proper locking in place
The check for IsActive is true. Since these are two instance of v8. One
with isolate2 and other with default isolate why is the lock active after
the thread A is executed?
