I am embedding V8 and trying to capture the current javascript stacktrace
using the "v8::StackTrace::CurrentStackTrace":
Isolate* isolate = info.GetIsolate();
Local<StackTrace> stack = v8::StackTrace::CurrentStackTrace(isolate, 10, v8
::StackTrace::StackTraceOptions::kDetailed);
*for* (*int* i = 0; i < stack->GetFrameCount(); i++) {
Local<v8::StackFrame> frame = stack->GetFrame(isolate, i);
Local<v8::String> funcName = frame->GetFunctionName();
v8::String::Utf8Value str(isolate, funcName);
*const* *char** name = *str;
printf("%s (%d:%d)\n", name, frame->GetLineNumber(), frame->GetColumn
());
}
I have placed this code inside a custom function that I have registered to
the global scope.
Before calling my custom function, I tried logging the stack property of an
Error object (by using : console.log(new Error().stack)) and I obtained the
following output:
Error
at bar (file:///app/bundle.js:266:29)
at test (file:///app/bundle.js:267:15)
at Observable.onTap (file:///app/bundle.js:268:11)
at Button.notify (file:///app/vendor.js:3620:32)
at Button._emit (file:///app/vendor.js:3640:18)
at TapHandlerImpl.tap (file:///app/vendor.js:15540:19)
With the "v8::StackTrace::CurrentStackTrace" method I get:
bar (266:29)
test (267:15)
(null) (268:11)
(null) (3620:32)
(null) (3640:18)
(null) (15540:19)
I am getting empty function names from some frames, while all the other
information is present (script name, line, column numbers, ...).
Do you know what might be the reason for getting empty function names?
