Several retry problems

[xmedeko]

Retry algorithm has several problems:

• Retry delay(ms) wait is not abortable by this._options.signal , see

  ky/source/core/Ky.ts

  Line 228 in 2049aff

  await delay(ms);

  • Check sindresorhus/delay 😉
• If Retry-After is 0, i.e. "retry immediately", then the request is not retried at all. (The problem is that 0 returned from _calculateRetryDelay is treaded as "stop retry").
• IMO if Retry-After is above maxRetryAfter, then it should be capped to maxRetryAfter and not that the retry is stopped. See

  ky/source/core/Ky.ts

  Line 194 in 2049aff

  if (typeof this._options.retry.maxRetryAfter !== 'undefined' && after > this._options.retry.maxRetryAfter) {
