Hi,
I have the following callback definition.
void Callback(const v8::FunctionCallbackInfo<v8::Value>& info)
{
string strLogLine = "";
v8::Isolate* pIsolate = info.GetIsolate();
for (int i = 0; i < info.Length(); i++)
{
strLogLine += " " +
string(*(v8::String::Utf8Value(info[i]->ToString(pIsolate))));
}
Log('i', strLogLine);
}
It worked fine, till today.
The callback is still called, but it crashes.
because the Utf8Value internally calls the Isolate::GetCurrent(), which
returns NULL. (check failed: isolate != NULL)
Can someone tell me in what cases the Isolate::GetCurrent() will return
NULL, and more precisely inside a callback function?
the function to execute javascript, which will trigger the callback
v8::Local<v8::Value> CScriptContext::ExecuteScript(const ustring &
strExpression, bool & bResult)
{
//Local variables
v8::Local<v8::Value> Result;
v8::Locker lock(m_pIsolate); // v8::Isolate * m_pIsolate
v8::EscapableHandleScope handle_scope(m_pIsolate);
v8::Local<v8::Context> Context = m_pContext->Get(m_pIsolate); //
v8::Persistent<v8::Context> m_pContext
v8::Context::Scope contextScope(Context);
v8::Local<v8::String> source =
v8::String::NewFromUtf8(m_pIsolate, strExpression.c_str());
v8::MaybeLocal<v8::Script> script = v8::Script::Compile(Context, source);
if (!script.IsEmpty())
{
v8::Local<v8::Script> v8LocalScript = script.ToLocalChecked();
Result = v8LocalScript->Run();
if (Result.IsEmpty()) {
VoxLog(M, 'W', F, L, "[JS][ScriptContext][ExecuteScript] result of the
executed script is empty");
bResult = false;
}
else
{
bResult = true;
}
}
else
{
bResult = false;
}
return handle_scope.Escape(Result);
}
