1354577 - use new service worker mime type restrictions

Status: RESOLVED FIXED

(Core :: DOM: Service Workers, enhancement, P2)

Description

[Ben Kelly [:bkelly, not reviewing]]

Spec change:

https://github.com/w3c/ServiceWorker/pull/1106

WPT change:

https://github.com/w3c/web-platform-tests/pull/5376

This widens the definition of what valid javascript mime types are.  Also, it tests that importScripts() mime types are enforced, which is something we don't currently do.

Attachment: Bug 1354577 - require ServiceWorkerGlobalScope.importScripts() to only accept JavaScript MIME types r?edenchuang

- Make ServiceWorkerGlobalScope.importScripts() throw a NetworkError when receiving a
bad (i.e. non-JavaScript) MIME type
- Correct registration-tests-mime-types.js to expect TypeError when registering
a service worker that calls importScripts() with a bad MIME type, per spec
- Add WPT import-scripts-mime-types.https.html to test importScripts success/failure,
depending on MIME type

Depends on D6416

I've documented this:

Made sure this restriction is mentioned on both relevant ref pages:
https://developer.mozilla.org/en-US/docs/Web/API/ServiceWorkerContainer/register
https://developer.mozilla.org/en-US/docs/Web/API/WorkerGlobalScope/importScripts

Added a note about it to the Fx65 rel notes:
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/65#APIs

Let me know if you think this needs anything else. Thanks!
