This bug appears to only be on Chrome due to the service worker fetching
the video content on page load instead of on play. For some reason
though the service worker would fetch around 4x more than the size of
the video resulting in excessive data being downloaded especially for
larger videos.

By default, the workbox-expiration plugin will not expire cache entries which include a `Vary` header in the response. This means that cached entries can build up until the browser storage quota is hit.
This commit introduces the `ignoreVary: true` option, so that deletion is performed correctly. This will only apply going forward, so this commit also bumps the cache version and deletes the old caches.

Previously workbox JS was vendored into our git repository, and would be loaded from the `public/javascripts` directory with a 1 day cache lifetime. The main aim of this commit is to add 'cachebuster' to the workbox URL so that the cache lifetime can be increased.
- Remove vendored copies of workbox.
- Use ember-cli/broccoli to collect workbox files from node_modules into assets/workbox-{digest}
- Add assets to sprockets manifest so that they're collected from the ember-cli output directory (and uploaded to s3 when configured)
Some of the sprockets-related changes in this commit are not ideal, but we hope to remove sprockets in the not-too-distant future.
This is necessary so MacOS Ventura (and in 2023 iOS) can use our new
default push notifications.
We still disable caching of dynamic routes on Apple devices due to it's
always being buggy there.
Allows quick inline replies in chat push notifications. This will allow users
in compatible platforms (Windows 10+ / Chrome OS / Android N+) to reply
directly from the notification UI.
Probable follow ups include:
- inline replies for posts
- handling failure of reply
- fallback to draft creation if business logic error
- store and try again later if connectivity error
- sent inline replies lack the in_reply_to param
- i18n of inline reply action text and placeholder
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
This is a workaround a behavior change in Chromium v97.
The following text was sent to the blink-dev mailing list:
> This change broke a SingleSignOn login on the FOSS software Discourse. We have a flow like:
>
> 1. User visits forum.siteA.com, click login
> 2. Gets redirected to idp.siteB.com
> 3. Fills login details
> 4. Gets redirected to forum.siteA.com/session/sso_login?parameters
> 5. Gets redirected to forum.siteA.com/homepage
>
> On step 4, the response includes a `set-cookie` header, with proper `HttpOnly; SameSite=Lax; Secure `and set. But if there is an active service worker, the login will fail as that cookie will be rejected by Chromium due to SameSite rules now.

A user browser may rotate a user subscription endpoint/keys
anytime.
Currently, Discourse will receive a 4XX response while trying to
deliver a push notification and silently unsubscribe the device.
With this change, we will gracefully handle desativating the old
subscription and the replacement creation with the need for the user
to resubscribe manually every time it breaks.

To prevent opaque cache files, now all the CDN files will be requested in 'cors' mode if the cdn_cors_enabled global setting is enabled. Before enabling the setting, should enable the cors in the CDN server by adding the response header `access-control-allow-origin: *` or `access-control-allow-origin: https://discourse.example.com.`
And other external file requests other than CDN will not be cached if the response type is opaque.
This reverts commit e3de45359f.
We need to improve out strategy by adding a cache breaker with this change ... some assets on CDNs and clients may have incorrect CORS headers which can cause stuff to break.
Only restricting cache per age wasn't enough for instances with lots of
multimedia usage and high number of posts.
MaxEntries is also more effective on cleanup, and purgeOnQuotaError
advertise that Discourse cache can be purged if necessary.

The special offline page with fetch interception in service worker
is only strongly required on Android ad a pre-req for PWAs
This is now strongly restricted only to Android while iOS PWA support
gets better
Long term if we build offline support we can unlock it more globally
* Feature: Push notifications for Android
Notification config for desktop and mobile are merged.
Desktop notifications stay as they are for desktop views.
If mobile mode, push notifications are enabled.
Added push notification subscriptions in their own table, rather than through
custom fields.
Notification banner prompts appear for both mobile and desktop when enabled.
