Happens commonly for e.g. replies to follower-only posts
if no one one your instance follows the replied-to account
or replies/quotes of deleted posts.
Before this change Masto API response would treat those
replies as root posts, making it hard to automatically or
mentally filter them out.
With this change replies already show up sensibly as
recognisable replies in akkoma-fe.
Quotes of unavailable posts however still show up as if they
weren’t quotes at all, but this can only be improved client-side.

It required a bunch of and even call-specific boilerplate
and is not necessary since we can just capture the real logger
as laready done in other tests.
While its data was included in healthcheck responses,
it was not used to determine the healthy status
and for informational purposes Prometheus metrics,
ObanWeb dashboard or the Phoenix live dashboard are all better fits.
In particular, the data shown in healtcheck responses had no temporal
information, but there’s quite a difference between X failures scattered
across many days of uptime and X failures within a couple minutes.
If the id of another activity type was used
it would show the post referenced by the activity
but wrongly attributing it to the activity actor
instead of the actual author.
E.g. ids of like activities can be obtained from
pagiantion info of the favourites endpoint.
For all other activity types the id would need to be guessed
which is considered practically infeasible for Flake UUIDs.
This should’ve been mostly harmless in practice, since:
- since the activity has the same context as the original post,
both the original and misattributed duplicate will show up in the
same thread
- only posts liked by a user can be misattributed to them,
presumably making it hard/impossible to associate someone with
content they disagree with
- by default only the liking user themself can view their like history
and therefore obtain IDs for their like activities.
Notably though, there is a user seting to allow anyone to browse
ones like history and therefore obtain like IDs. However, since
akkoma-fe has no support for actually displaying those, there might
be no actual users of this features.
This is more intuitive for users.
On the flip side, this makes the API more confusing
since now min_id/max_id no longer correspond to ids returned in the
response and only link headers can be used to traverse all response
pages. However, Mastodon already does this according to its
documentation, so clients should already handle this well.
The only other usage of get_follow_requests_query is only interested
in the total count of requests (from active users), thus changing its
select part is safe.
Also gets rid of (outside tests unused) User.get_follow_requests.

The old approach required adding a special virtual field
to any table potentially needing such foreign-id pagination and
also still required manually sorting according to pagiantion settings
since the pagination helper does not know whether
this virtual field was set or not.
Using lists with each entry containing the pagination id and the actual
entry insterad allows any table to use this mechanism unchanged and
does not require manually sorting.
Since it was unused, this also drops the pagination mode paramter from
fetch_favourited_with_fav_id.
Furthermore, as a side effect of this change a bug in the favourite
benchmark is fixed. It used to incorrectly attempt to use IDs of
the liked objects for pagination instead of the like IDs as advertised
in Link headers.
It’s only used in one place and there not even all of
its functionality is needed. It’s not only simpler and shorter,
but easier to understand if Tesla’s keyword list is just inlined.
The only useful bit which is now migrated to Pleroma.HTTP is
addition of the user-agent header (except, sometimes, in tests)
The Signature module now handles interaction with the HTTPSignature library
and the plug everything related to HTTP itself. It now also no longer needs to be public.
To achieve this signatures are now generated by a custom
Tesla Middleware placed after the FollowRedirects Middleware.
Any requests which should be signed needs
to pass the signing key via opts.
This also unifies the associated header logic between fetching and
publishing, notably resolving a divergence wrt the "host" header.
Relevant spec demands the host header shall include a port
identification if not using the protocols standard port.

The remote part is included in federated emoji names by e.g.
Iceshrimp.NET ever since remote emoji support was added in
4d21aa1670
and as of writing it still continues to do so.
It adds no value for us though; we add the remote part automatically
based on the URL and it makes it more difficult to correctly coalesce
the original reaction (from a user for whom the moji was local)
and the subsequent reactions with the identical emoji from users of
other instances. Additionally the remote part can cause issues when
later used with our REST API.
For non-reactions this is unproblematic and thus
there’s no need to change anything there.
Use a migration to fix up existing activities.
This will cause some (further) desync from the inlined reactions
array, but will be fixable with the resync mix task and avoids
issues when running the resync without first fixing existing activities.
ActivityPub spec demands each actor has at least an inbox and outbox.
Furthermore, the current representation wouldn’t even be accepted by
ourselves, since our processing requires objects to be flagged with a
sensible type else we don't know what to do with it.
Including the nickname is just a peemptive measure.
There were no reports of this causing problems in real-world deployments
and at least for federation with other Akkoma instances we should have
never run into this, since we _always_ expose the full representation of
the instance actor and atm also always use the latter for fetching
remote content (which prevents us from fetching followers-only content).
Nonetheless, serving something which violates spec and we wouldn’t even
accept ourselves seems obviously bad, so fix it and add tests to prevent
this from reoccuring.

The old code was unnecessarily complicated, full of unused and/or
duplicated functions making it hard to understand what will actually
happen and for whom at runtime.
Since we only support a single HTTP backend this can be greatly simplified.
Now everything gets default options from a single place and only
functions to modify parts actually difffering across calls are exposed.
the :do_not_federate checks were omitted from the undo pipeline,
which could lead to them federating.
this commit enforces :outgoing_blocks on undos as well - and
any existing value of :do_not_federate is preserved, if one exists

Resolves interop issue with a (reverted but possibly returning) bridgy change
as was reported in the comments of
https://akkoma.dev/AkkomaGang/akkoma/issues/831.
This won't change anything for the problem originally reported there.
Notably we now always fetch the full collection (up to the configured
item count limit) instead of only using the first page if its link was
inlined.
- This adds extra tests to be sure that scrubbing still happens.
- When doing this I notices that the htmlMfm key wasn't stored in the database when comming through the federator. This has been now been fixed too.
- We also test that values true, false or no attribute all work for incomming messages.
Previously all such requests led to '401 Unauthorized'
whih might have triggered retries.
Now, to not leak any MRF info, we just indicate an
accept for POST requests without actually processing the object
and indiscriminately return "not found" for GET requests.
Notably this change also now causes all signed fetch requests from
blocked domains to be rejected even if authorized_fetch isn’t enabled.

A pool timeout shorter than the receive timeout
makes race conditions leading to active connections
being killed more likely and laso just doesn’t make
much sense in general.

Until now only a limited number of self-replies were inlined as an
anonymous, unordered ActivityPub collection. Notably the advertised
replies might be private posts.
However, providing all (non-private) replies allows for better thread
consistency across instances if the remote server cooperates.
The collection existing as a stndalone object has two advantages
for this. For one, if it was still anonymous, _all_ replies would need
to be inlined, which might be too bloated in pathological cases.
Secondly, it allows remote servers to update the thread by traversing
the reply collection independent of the original post. (If the remote
part knows about chronological ordering, it can in theory
even efficiently resume from where it previously stopped)
This requirement was originally added together with splicing the
inbox owner into the non b* addressing fields to make bcc transports
work in https://git.pleroma.social/pleroma/pleroma/-/merge_requests/390.
Later on this was relaxed to always allow deliveries devoid of any
addressing at all in f6cb963df2
and always allow deliveries from actors the owner is following in
750b369d04 to fix interop issues with
Mastodon and Honk respectively.
The justification for both the filtering and splicing comes from
one sentence in AP spec’s inbox section:
> In general, the owner of an inbox is likely
> to be able to access all of their inbox contents.
While this may provide plausible justification for splicing the owner
into cc, it is less clear how this requires or justifies the set of
filtering rules employed here.
Surveying a few other implementations no similar
filtering or splicing appears to be employed.
Furthermore, spec-compliant servers will strip bto/bcc _before_
delivery to remote servers, meaning any compliant bcc transport
out there will NOT contain any explicit addressing of the inbox owner.
Thus the addressing requirement directly opposes
the goal of the original patch.
Currently the requirement for the owner to be addressed once again
is causing interop issues. It turns out to be the root cause of
a long-standing (2+ years) bug preventing meaningful federation.
Bridgy sends e.g. Follow activities and Accepts for Follows directly
to the affected user’s personal inbox while solely addressing
the public scope in the to field. Notably follow relations never
getting established prevented the "accept if followed" allow rule
to ever come into effect.
To make matters worse non-addressed messages simply lead to a
vague "internal server error" response being sent back
which likely slowed down locating the issue.
Furthermore additional issues wrt to signatures cropped up after
the 500-response issues wa first reported, but they seem to have
already been fixed in the meantime, possibly with the signature
handling overhaul in Akkoma.
Given it repeatedly caused issues, does not appear to align with common
practice in the wider fedi ecosystem and apparently contradicts its
original intention, simply remove the requirement.
This is confirmed to fix bridgy interop.
The addressing splicing actually should also add the inbox owner to bto
or bcc instead of cc, but for now this is not changed and in practice
bto/bcc delivery appears to be basically unused anyway.
Most headers are automatically checked by the library after this
upgrade. But since digest is only required for requests with a body
and body processing is handled outside the lib atm, we need to
explicity pass the presence or absence along or not get feedback
about creating broken signatures.
This makes bugs in our signatures more apparent
allowing faster discovery and fixing
This property was introduced as a way to gauge whether and
how much enabling authfetch might break passive federation in
https://akkoma.dev/AkkomaGang/akkoma/pulls/312.
However, with the db field defaulting to false, there’s no distinction
between instances without valid signatures and those which just never
attempted to fetch anything from the local instance.
Furthermore, this was never exposed anywhere and required manually
checking the database or cachex state via a remote shell.
Given the above it appears this doesn't actually
provide anything useful, thus drop it.
Only scrubbing "content" leads to differences between
"content" and "contentMap" eventhough the latter should
ideally match the former exactly for the primary language’s entry.
While ideally, for locally generated posts there should be no difference
between applying the scrubber or not, as it turns out automatically
generated attachment links didn't match the form expected by our default
scrubber.
Currently Akkoma never uses nor exposes the value of contentMap entries,
thus this oversight was harmless wrt to safety and at most pertubed
the language detection for our posts perfomed by remote servers.

Despite its name this property is not supposed to be a full URI,
but just a bare domain witout protocol. Furthermore, it’s supposed
to be the WebFinger domain used in userhandles and NOT the domain used
for API and ActivityPub objects (which every caller will already know
anyway).
Not following this caused issues for Pachli and Tusky.

This allows to retain posts and boosts of remote actors with local
follows regardless of age.
With the "full" setting this can be taken further treating such
followed actors just like local users even keeping all posts they
liked or reacated to.
Pinned objects and their threads will be refetched
on user refresh which by default happens after a day
once a user is encountered again in any form including a mention.
We observed pruning pinned objects usually results in heavy load for
hours after a database prune due to a clogged up remote fetch queue as
pinned posts and their threads of many (most?) users get refetched.
Thus do not prune pinned posts by default.
Keeping closer to earlier behaviour this will still prune threads of
pinned posts regardless of --keep-threads if nothing else prevenets it.
In theory a pedantic reading of the spec indeed suggests
DMs must only be delivered to personal inboxes. However,
in practice the normative force of real-world implementations
disagrees. Mastodon, Iceshrimp.NET and GtS (the latter notably has a
config option to never use sharedInboxes) all unconditionally prefer
sharedInbox for everything without ill effect. This saves on duplicate
deliveries on the sending and processing on the receiving end.
(Typically the receiving side ends up rejecting
all but the first copy as duplicates)
Furthermore current determine_inbox logic also actually needs up
forcing personal inboxes for follower-only posts, unless they
additionally explicitly address at least one specific actor.
This is even much wasteful and directly contradicts
the explicit intent of the spec.
There’s one part where the use of sharedInbox falls apart,
namely spec-compliant bcc and bto addressing. AP spec requires
bcc/bto fields to be stripped before delivery and then implicitly
reconstructed by the receiver based on the addressed personal inbox.
In practice however, this addressing mode is almost unused. Neither of
the three implementations brought up above supports it and while *oma
does use bcc for list addressing, it does not use it in a spec-compliant
way and even copies same-host recipients into cc before delivery.
Messages with bcc addressing are handled in another function clause,
always force personal inboxes for every recipient and not affected by
this commit.
In theory it would be beneficial to use sharedInbox there too for all
but bcc recipients. But in practice list addressing has been broken for
quite some time already and is not actually exposed in any frontend,
as discussed in https://akkoma.dev/AkkomaGang/akkoma/issues/812.
Therefore any changes here have virtually no effect anyway
and all code concerning it may just be outright removed.
