url: URLPattern rejects values requiring WebIDL USVString conversion for input and baseURL

Inizia con i punti di ingresso del costruttore node:url URLPattern, di test() e di exec(), quindi esegui la riproduzione sull’ultimo branch main. Confronta la gestione degli argomenti con le regole citate di risoluzione degli overload WebIDL e di USVString. Il lavoro è completato quando gli input numerici e i valori object baseURL producono i risultati attesi invece di ERR_INVALID_ARG_TYPE, con copertura di regressione per i casi mostrati.

What steps will reproduce the bug?

  const { URL, URLPattern } = require('node:url');

  const base = 'https://example.com/';
  const numberPattern =
    new URLPattern('https://example.com/123');
  const fooPattern =
    new URLPattern('https://example.com/foo');

  const baseObject = {
    toString() {
      return base;
    },
  };

  const baseURLObject = new URL(base);

  function observe(label, callback) {
    try {
      console.log(label, callback());
    } catch (error) {
      console.log(label, error.code, error.name);
    }
  }

  // URLPatternInput conversion.
  observe(
    'constructor input:',
    () => new URLPattern(123, base).pathname,
  );

  observe(
    'test input:',
    () => numberPattern.test(123, base),
  );

  observe(
    'exec input:',
    () => numberPattern.exec(123, base) !== null,
  );

  // baseURL conversion. The three-argument constructor is intentional:
  // it unambiguously selects the baseURL overload.
  observe(
    'constructor baseURL:',
    () => new URLPattern('foo', baseObject, {}).pathname,
  );

  observe(
    'test baseURL:',
    () => fooPattern.test('foo', baseURLObject),
  );

  observe(
    'exec baseURL:',
    () => fooPattern.exec('foo', baseURLObject) !== null,
  );

How often does it reproduce? Is there a required condition?

Every

What is the expected behavior? Why is that the expected behavior?

  constructor input: /123
  test input: true
  exec input: true
  constructor baseURL: /foo
  test baseURL: true
  exec baseURL: true

What do you see instead?

Each case throws a TypeError with code === 'ERR_INVALID_ARG_TYPE'.

Additional information

The URL Pattern IDL (https://urlpattern.spec.whatwg.org/#urlpattern) defines:

typedef (USVString or URLPatternInit) URLPatternInput;

constructor(
URLPatternInput input,
USVString baseURL,
optional URLPatternOptions options = {}
);

constructor(
optional URLPatternInput input = {},
optional URLPatternOptions options = {}
);

boolean test(
optional URLPatternInput input = {},
optional USVString baseURL
);

URLPatternResult? exec(
optional URLPatternInput input = {},
optional USVString baseURL
);

WebIDL requires JavaScript values assigned to USVString to undergo USVString conversion
(https://webidl.spec.whatwg.org/#es-USVString), rather than already being JavaScript String values.

The constructor must first perform WebIDL overload resolution (https://webidl.spec.whatwg.org/#dfn-overload-resolution-algorithm).
