Bug 204414 – Incorrect association of the URL object with the value port

• Component: DOM
• Status: RESOLVED FIXED

[Ivan Demidov]

const {hostname, port} = location;
const pathname = 'websocket';
const protocol = 'wss:'
const target = {hostname, pathname, port, protocol, search: ''};

Object.assign(new URL(location), target);

as a result of merging the above code, 0 value gets to the port

URL {
  hash: ""
  host: "bugs.webkit.org:0"
  hostname: "bugs.webkit.org"
  href: "wss://bugs.webkit.org:0/websocket"
  origin: "wss://bugs.webkit.org:0"
  password: ""
  pathname: "/websocket"
  port: "0"
  protocol: "wss:"
  search: ""
  searchParams: URLSearchParams {append: function, delete: function, get: function, getAll: function, has: function, …}
  username: ""
}

Not related to this change, but it's a bit odd we use toUInt() here, rather than toUIntStrict(), since the former allows trailing garbage. Probably worth testing, but not in this change. (I also kind of want to change the toNumber functions to return Optionals).

[Alex Christensen]

Chromium allows trailing garbage, Firefox does not, the spec is a little unclear and seems to me that it would allow url.port="123?query" to override the path and query, but no browser allows that.  I'm going to commit this as-is right now to save the toUIntStrict discussion for another day, because it doesn't seem to be causing compatibility problems in practice now.
