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.
The most common permanent receiver error arises for likes/boosts
when we don’t yet know the rlevant object and can't fetch it
due to the remote being overwhelmed or otherwise down.
Before this changes all retries were rather rapid
thus not giving the remote enough time to recover
and usually all failing. Now the remote has about 20
minutes to recover before we give up.
Transient errors from race conditions and (presumably)
weird database-cache interactions also occur regularly.
However, they resolve within the first one or two retries
and those intial retries still happen relatively quickly.
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.

Added in Mastodon 2.9.2 (June 2019) this is plain-text-only and supposed
to be shorter compared to the older description field.
Some clients were reported to require this field to properly function.

jobs getting scheduled each week but never processed
forever lingering in 'available' state.

And use the project’s preferred spelling when

Spelling of RedHat packages was left as is

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.
Statmenets for keeping and breaking threads vastly differ
and the whole if block doesn't even fit on one screen.
Thus move each version out into its own function to
improve readability
Since bcfbfbcff5 (part of
<https://akkoma.dev/AkkomaGang/akkoma/pulls/789>), the overhead for
cleaning up orphaned attachments has been drattically reduced.
Most admins are unaware of this option even existing, but may notice an
increase in the size of the uploads directory (or S3 bucket size if used
instead) even if auto-expiring posts are used. This should hopefully
make this problem more manageable.
For those that still encounter performance issues, the setting can still
be disabled if needed.
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.
