fs: special input `-1` on `chown`, `lchown` and `fchown` by himself65 · Pull Request #58836 · nodejs/node

himself65 · 2025-06-25T17:35:29Z

Fixes: #58826

-1 is a special input for chown, means won't change anything according to the spec.

+    } else {
+      CHECK(value->IsNumber());
+    }
    return static_cast<T>(value.As<v8::Uint32>()->Value());


Pretty sure that at least according to the V8 API contract, IsUint32() is a prerequisite for this case to be valid in the first place – overall, I'd say it's better to handle these values in the *Chown functions rather than in the generic helpers here
