1009199 - Proxy [[Get]] is completely mistreated for prototypically inherited proxies

Status: RESOLVED DUPLICATE of bug 914314

(Core :: JavaScript: Standard Library, defect)

Description

[Eric Faust [:efaust]]

The spec specifies that the [[Get]] operation looks like this:

When we need to do a get on O

Invoke [[GetOwnPropertyDescriptor]] on O
if that's undefined:
    Invoke [[GetPrototypeOf]] on O
    if that's not null:
        Invoke [[Get]] on the prototype

So, for an inherited proxy, we should only see the [[Get]] trap called. No [[HasProperty]] or [[GetOwnProperty]] or anything like that.

Sadly, this is not the case. [[HasProperty]] is called, and *NOT* [[Get]].

This is analgous to the failure mode in bug 979671

I just missed the existence of 914314 when I filed this. It's the same.
