What steps will reproduce the bug?
const vm = require("vm");
let impl = { status: "" };
let ctx = vm.createContext();
Object.defineProperty(ctx, "status", {
configurable: true,
enumerable: true,
get() {
return impl.status;
},
set(v) {
impl.status = `${v}`;
}
});
// https://github.com/web-platform-tests/wpt/blob/master/xhr/status-async.htm
vm.runInContext(`
function statusRequest(...args) {
console.log(args.map(JSON.stringify).join("\t"));
}
function status(code, text, content, type) {
statusRequest("GET", code, text, content, type);
statusRequest("HEAD", code, text, content, type);
statusRequest("CHICKEN", code, text, content, type);
}
status(204, "UNICORNSWIN", "", "")
status(401, "OH HELLO", "Not today.", "")
status(402, "FIVE BUCKS", "<x>402<\/x>", "text/xml")
status(402, "FREE", "Nice!", "text/doesnotmatter")
status(402, "402 TEH AWESOME", "", "")
status(502, "YO", "", "")
status(502, "lowercase", "SWEET POTATO", "text/plain")
status(503, "HOUSTON WE HAVE A", "503", "text/plain")
status(699, "WAY OUTTA RANGE", "699", "text/plain")
`, ctx);How often does it reproduce? Is there a required condition?
Always.
What is the expected behavior?
The functions get defined using [[DefineOwnProperty]] as specified in ECMA‑262 § 8.1.1.4.18 CreateGlobalFunctionBinding.
