Inspect commands can't handle Symbol attributes (e.g. @@toStringTag and @@unscopable), resulting in <non-string> properties.
For example, the following code uses the @@toStringTag symbol:
class Bar {
constructor() {
this[Symbol.toStringTag] = "Bar";
}
}
let bar = new Bar();If we use llnode to find out the properties for bar, it will give the following output:
(lldb) v8 findjsinstances -v Bar
0x0000015078184729:<Object: Bar properties {
.constructor=0x00000150781846e1:<function: Bar at index.js:17:14>}>
0x0000015078184949:<Object: Bar properties {
.<non-string>=0x00002d2064acb1e1:<String: "Bar">}>
As you can see, there's a <non-string> property instead of our symbol.
I was looking at llnode and V8 code to try to find a solution, but I'm not sure how to implement it. Did anyone try this before?
