- YouTube has started responding to video page requests with localised content when requested from certain IPs, with that localised content not containing the required `<link rel="alternate" ...>` tag pointing to the oembed endpoint
- we were fetching video pages rather than the oembed endpoint for YouTube Live URLs because they are not recognised by the oembed extraction library we use
- by modifying the URL from a live URL to a watch URL before we perform oembed lookup/extraction we are able to bypass the (localised) page fetch and instead grab the oembed content directly
https://github.com/TryGhost/Ghost/issues/20445
- after switching to a browser-like user-agent, YouTube started responding with a "supported browsers" message rather than the actual video meaning bookmark creation failed
- when trying other user-agents it was discovered that nytimes.com (why the user-agent was originally changed) had a problem with the github.com address in the user-agent. By switching to using https://ghost.org instead the request was allowed through fixing both YouTube and NYTimes embeds
closes https://linear.app/tryghost/issue/ENG-762
- nytimes.com and other sites return 403 responses when requests do not match typical browser user-agents
- our bookmark fetching requests were using `Ghost(https://github.com/TryGhost/Ghost)` meaning bookmark creation failed for these user-agent-blocking sites
- switched to using a standard browser user-agent string to avoid such blocks
closes https://github.com/TryGhost/Ghost/issues/20028
It's fairly common practice for oembed providers to skip some of the "required" fields from the oembed spec such as `height` when it doesn't make sense for the embeddable content, this was the case with Bluesky embeds which return `height: null`
- removed validation for `height` being present in the response for it to be recognised as an embed because we don't use it anywhere and the validation is blocking otherwise valid embeds

- added request queueing middleware (express-queue) to handle high
request volume
- added new config option `optimization.requestQueue`
- added new config option `optimization.requestConcurrency`
- added logging of request queue depth - `req.queueDepth`
We've done a fair amount of investigation around improving Ghost's
resiliency to high request volume. While we believe this to be partly
due to database connection contention, it also seems Ghost gets
overwhelmed by the requests themselves. Implementing a simple queueing
system allows us a simple lever to change the volume of requests Ghost
is actually ingesting at any given time and gives us options besides
simply increasing database connection pool size.

fixes https://github.com/TryGhost/Product/issues/4237
- this fixes the fact that we return a HTTP 500 response when the oembed
library receives an error, such as a 401 or 403
- includes special handling for cases where we want to return a slightly
different error message
- also adds unit tests for @tryghost/oembed-service package
- this version is written in TS, but was published a few months ago and
needs to be bumped here
- also updates a previous deep include into the library, which was
unnecessary anyway
refs. https://linear.app/tryghost/issue/DES-122/bookmark-card-issues
This PR addresses the following content card related problems:
1. The design of the following cards are more self-contained so it makes
more sense to use `px` for their font-sizes and spacings so it looks the
same regardless of the theme. Of course themes still can override these
values.
Updated cards to use `px` for font sizing:
- audio
- bookmark
- file
- product
2. So far header and signup cards had been using `rem` for font-sizes
and some sizing. This commit updates these to use `em` instead so that
it's consistent with all other cards.
3. The favicon sometimes is not available for bookmark cards. This PR also
fixes that by providing a default favicon for these cases.

- issue reported via the forum https://forum.ghost.org/t/video-embed-break-page-on-mobile/44172
- due to historical issues we check against http/https and non-www/www URLs to match an oembed provider in case our library's provider list is out of date. However we checked http first which could match and then update the original URL to be `http` in place of `https` leading to potentially broken oembed fetch requests as was the case with http://odysee.com URLs

- Added a recheck for recommendation related webmentions after boot (to
check missed webmentions during down time)
- Increased general timeouts to 15s for all webmention related HTTP
requests. Instead, increased retries to 3.
- Increased timeout for fetching webmention metadata from 2s to 15s
- Added more logging about verification and deletion status of
webmentions
no issue
- recently added code to grab apple touch icons or SVGs before falling back to the default metascraper behaviour wrongly assumed that every size would have a `rel` and `href` attribute which is not the case

We're rolling out new rules around the node assert library, the first of which is enforcing the use of assert/strict. This means we don't need to use the strict version of methods, as the standard version will work that way by default.
This caught some gotchas in our existing usage of assert where the lack of strict mode had unexpected results:
- Url matching needs to be done on `url.href` see aa58b354a4
- Null and undefined are not the same thing, there were a few cases of this being confused
- Particularly questionable changes in [PostExporter tests](c1a468744b) tracked [here](https://github.com/TryGhost/Team/issues/3505).
- A typo see eaac9c293a
Moving forward, using assert strict should help us to catch unexpected behaviour, particularly around nulls and undefineds during implementation.
