This module handles signing and validating HTTP signatures, which is a core
part of interfacing with ActivityPub enabled servers.

https://linear.app/tryghost/issue/ENG-902/add-an-optional-timeout-in-the-redis-cache-adapter-in-case-redis
- Added an optional timeout parameter to AdapterCacheRedis, so that the
`get(key)` method will return `null` after the timeout if it hasn't
received a response from Redis
- When load testing the `LinkRedirectRepository` with the Redis cache
enabled on staging, we noticed that for some reason Redis stopped
responding to commands for ~30 seconds.
- The `LinkRedirectRepository` was waiting for the Redis cache to
respond and resulted in a drastic increase in response times for link
redirects
- This change will allow us to set a timeout on the `get(key)` method,
so that if Redis doesn't respond within the timeout, the method will
return `null` as if it were a cache miss.
- Then the `LinkRedirectRepository` will fall back to the database and
return the link redirect from the database instead of waiting
indefinitely for Redis to respond
fix https://linear.app/tryghost/issue/SLO-93/undefined-path-error-with-bad-image-upload
- in the event we receive a request to upload an image, that doesn't
contain an image, we still try and unlink the files
- this is a dangling promise, so it doesn't cause an explicit HTTP
error, but it does show up as a console error
- fixed it by checking for the path, and early returning if it doesn't
exist
- also added a test that would fail without this
ref https://linear.app/tryghost/issue/SLO-78
- the `POST /members/api/member` endpoint is solely used by the alpha
feature `membersSpamPrevention` and should not be available otherwise
fix https://linear.app/tryghost/issue/SLO-88/typeerror-cannot-read-properties-of-null-reading-relations
- in the event that we make it through the version mismatch code, but
without a key, which is possible if you send a request like POST
/ghost/api/v2/content/posts/`, then the version mismatch code will try
and look up the API key attached to a null key, which won't work
- we should handle this case and soft return, to avoid trying to read
`.relations` from `null`
- I'm not entirely convinced by how this code works in general, it seems
quite confusing to reason about, but this commit should solve the HTTP
500 we've been seeing from this
- perhaps in the future we can return earlier in the flow if we receive
a `null` key
ref https://linear.app/tryghost/issue/ENG-881/stripe-tax-checkout-instantiation-fails-for-free-members-when-choosing
- For existing customers to be able to upgrade their account with automatic tax enabled, we need to pass in `customer_update[address]:auto` as per Stripe documentation.
- Automatic tax calculation in Checkout requires a valid address on the Customer. Add a valid address to the Customer or set either 'customer_update[address]' to 'auto' or 'customer_update[shipping]' to 'auto' to save the address entered in Checkout to the Customer.
- We update the existing customer details by passing in address `auto` when they upgrade their accounts.
- Stripe captures the billing address information by default when new accounts are created and then that is used to calculate the tax rate.
ref https://linear.app/tryghost/issue/ENG-842/gluster-file-name-length-limit
- when uploading a theme, Admin did not always render errors properly, zip extraction errors for example
- with this change, we do not change the API responses but rather update Admin to handle both types of error responses
fix https://linear.app/tryghost/issue/SLO-82/query-error-unexpected-character-in-filter-at-char-1
- previously, we weren't handling a parsing error, and just bubbling it
back up the chain
- this would result in an InternalServerError somewhere, which caused
500s
- we can handle this, because it's just a bad filter
- this adds handling so we return a 422 upon receiving an invalid filter
fix https://linear.app/tryghost/issue/SLO-79/incorrectusageerror-the-url-httpsblogkongregatecompercentc0-couldnt-be
- we added this Sentry captureException whilst fixing a bug where
decodeUrl could fail, and throw a 500 exception
- we added handling for that case and returned an empty string, but we
also added Sentry error capturing
- at this point, I don't think we need to be capturing errors in Sentry,
because the issue is already handled, and it only usually happens with
malicious/incorrect URLs
- this is our #2 cause of Sentry alerts, so it's good to clean it up
ref https://linear.app/tryghost/issue/ENG-881/stripe-tax-checkout-instantiation-fails-for-free-members-when-choosing
- For existing customers to be able to upgrade their account with automatic tax enabled, we need to pass in `customer_update[address]:auto` as per Stripe documentation.
- Automatic tax calculation in Checkout requires a valid address on the Customer. Add a valid address to the Customer or set either 'customer_update[address]' to 'auto' or 'customer_update[shipping]' to 'auto' to save the address entered in Checkout to the Customer.
- We update the existing customer details by passing in address `auto` when they upgrade their accounts.
- Stripe captures the billing address information by default when new accounts are created and then that is used to calculate the tax rate.
- we don't need to deep require into the library as it exports what we
need on the surface
- this should unblock https://github.com/TryGhost/Ghost/pull/19002, as
it's randomly failing with this require

[ENG-827](https://linear.app/tryghost/issue/ENG-827/🐛-crash-on-resizing-animated-gif)
Added a timeout to the image resizing middleware to prevent crashes when
an image is taking too long to resize. When the timeout is reached and
the image has not been resized, the middleware will return the original
image
closes https://linear.app/tryghost/issue/MOM-60
- when the dropdown opens near the end of the document, clicking the links sometimes did nothing and showed an error in the console
- we have a mousedown event handler on an element that surrounds the main editing element that re-focuses the editor when clicked in order to make the "focus editor" click target larger and more natural-feeling but it was inadvertently re-focusing when the mousedown event fired for an element in the dropdown list when the list was positioned outside of the main editor element. This lead to timing issues with the bookmark node being removed on blur because it was empty followed by an error from the node's component's async event handlers which were trying to set values on the now-removed node
- by switching from `event.target.closest()` to looping over `event.composedPath()` when checking to see if we should skip re-focusing we're more resilient to DOM manipulations occurring between event triggers and function calls because we'll always be given the list of elements that existed at the time the event fired

- used the default TabView component on Offers list for better consistency
- added new property to TabView component which makes it possible to have extra content on the top right
- updated copy of the empty states

https://linear.app/tryghost/issue/ENG-851/implement-a-minimal-but-complete-version-of-redirect-caching-to
ref https://app.incident.io/ghost/incidents/55
Often immediately after sending an email, sites receive a large volume
of requests to LinkRedirect endpoints from members clicking on the links in
the email.
We currently don't cache any of these requests in our CDN, because we
also record click events, update the member's `last_seen_at` timestamp,
and send webhooks in response to these clicks, so Ghost needs to handle
each of these requests itself. This means that each of these LinkRedirect requests
hits Ghost, and currently all these requests hit the database to lookup
where to redirect the member to.
Each one of these requests can make up to 11 database queries, which can
quickly exhaust Ghost's database connection pool. Even though the
LinkRedirect lookup query is fairly cheap and quick, these queries aren't
prioritized over the "record" queries Ghost needs to handle, so they can
get stuck behind other queries in the queue and eventually timeout.
The result is that members are unable to actually reach the destination
of the link they clicked on, instead receiving a 500 error in Ghost, or
it can take a long time (60s+) for the redirect to happen.
This PR uses our existing `adapterManager` to cache the redirect lookups
either in-memory or in Redis (if configured — by default there is no caching). This only removes 1 out of
11 queries per redirect request, so it won't reduce the load on the DB
drastically, but it at least decouples the serving of the LinkRedirect from
the DB so the member can be redirected even if the DB is under heavy
load.
Local load testing results have shown a decrease in response times from
60 seconds to ~50ms for the redirect requests when handling 500 requests
per second, and reduced the 500 error rate to 0.
