Bug ID: 183115
Summary: Web Inspector: Object.shallowCopy(obj) should always
equal shallowEqual
Product: WebKit
Version: WebKit Nightly Build
Hardware: All
OS: All
Status: NEW
Severity: Normal
Priority: P2
Component: Web Inspector
Assignee: webkit-unassigned at lists.webkit.org
Reporter: nvasilyev at apple.com
CC: inspector-bugzilla-changes at group.apple.com
let copy = Object.shallowCopy(obj);
Object.shallowEqual(obj, copy); // true only if obj is a plain object, e.g. obj.constructor === Object
I find it's odd that a shallow copy of an object may NOT equal to the original object.
This can be fixed by:
A. Using Object.setPrototypeOf for Object.shallowCopy, which is very slow https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/setPrototypeOf
B. Reverting Bug 161852: Web Inspector: Object.shallowEqual() should return false if object prototype chains differ
I like option B.
