Hi,
I am trying to find every *undefined* property lookup in my codebase for
code analysis. I thought it would be most straightforward to add a few
lines in the get object property part in Node.js(v8). After a day of hard
work, I finally make a progress: I added the following code to the
`Runtime::GetObjectProperty` function in
`./deps/v8/src/runtime/runtime-object.cc`.
```cpp
if(result.ToHandleChecked()->IsUndefined(isolate)){
printf("[!] Found undefined property: ");
lookup_key.GetName()->NameShortPrint();
printf("\n");
}
```
However, it doesn't print the stuff I want. When I try it with a simple
case, it outputs something shown below:
```js
a = {
"nohello": 1
}
console.log(a.hello);
```
Output by the revised Node.js
```console
[!] Found undefined property: <kHandle>
[!] Found undefined property: <kHandle>
[!] Found undefined property: <kHandle>
[!] Found undefined property: /home/x/tmp/test.js
[!] Found undefined property: MODULE
[!] Found undefined property: /home/x/tmp/test.js
undefined
[!] Found undefined property: beforeExit
```
Expected output
```console
[!] Found undefined property: <a:hello>
```
Is there anyone who can help me to achieve this feature?
Happy Thanksgiving:>
