literally nothing uses C2S AP, and it's another route into core
systems which requires analysis and maintenance. A second API
is just extra surface for potentially bad things so let's take
it out back and obliterate it
by default just prevent job floods with a 1-seconds
uniqueness check, but override in RemoteFetcherWorker
for 5 minute uniqueness check over all states
:infinity is an option we can go for maybe at some point,
but that would prevent any refetches so maybe not idk.
We were overzealous with matching on a raw error from the object fetch that should have never been relied on like this. If we can't fetch successfully we should assume that the collection is private.
Building a more expressive and universal error struct to match on may be something to consider.
These tests relied on the removed Fetcher.fetch_object_from_id!/2 function injecting the error tuple into a log message with the exact words "Object containment failed."
We will keep this behavior by generating a similar log message, but perhaps this should do a better job of matching on the error tuple returned by Transmogrifier.handle_incoming/1
"id" is used for the canonical link to the AS2 representation of an object.
"url" is typically used for the canonical link to the HTTP representation.
It is what we use, for example, when following the "external source" link
in the frontend. However, it's not the link we include in the post contents
for quote posts.
Using URL instead means we include a more user-friendly URL for Mastodon,
and a working (in the browser) URL for Threads
previously we would uncritically take data and format it into
tags for static-fe and the like - however, instances can be
configured to disallow unauthenticated access to these resources.
this means that OG tags as a vector for information leakage.
_technically_ this should only occur if you have both
restrict_unauthenticated *AND* you run static-fe, which makes no
sense since static-fe is for unauthenticated people in particular,
but hey ho.
