What steps will reproduce the bug?
related: #39759
According to the specification, the structuredClone
options do not take a list of transfers as an array. This is different from postMessage
.
https://html.spec.whatwg.org/multipage/structured-data.html#structured-cloning
https://html.spec.whatwg.org/multipage/web-messaging.html#message-ports
const value = new Uint8Array(4);
// valid
port.postMessage(value, [value.buffer]);
// valid
port.postMessage(value, { transfer: [value.buffer] });
// invalid (No transfer)
structuredClone(value, [value.buffer]);
// valid
structuredClone(value, { transfer: [value.buffer] });
minimum test code:
import assert from "assert";
const value = new Uint8Array(4);
structuredClone(value, [value.buffer]);
assert( value.length !== 0 );
How often does it reproduce? Is there a required condition?
