E.g. Flag activities have an array of objects
We prune the activity when NONE of the objects can be found
Note that the cost of finding and deleting these is ~4x higher than finding and deleting the non-array ones
Only string:
Delete on activities (cost=506573.48..506580.38 rows=0 width=0)
Only Array:
Delete on activities (cost=3570359.68..4276365.34 rows=0 width=0)
(They are still executed separately, so the total cost is the sum of the two)
We add an option to also prune remote activities who don't have existing objects any more they reference.
Rn, we only check for activities who only reference one object, not an array or embeded object.
This adds an option to the prune_objects mix task.
The original way deleted all non-local public posts older than a certain time frame.
Here we add a different query which you can call using the option --keep-threads.
We query from the activities table all context id's where
1. the newest activity with this context is still old
2. none of the activities with this context is is local
3. none of the activities with this context is bookmarked
and delete all objects with these contexts.
The idea is that posts with local activities (posts, replies, likes, repeats...) may be interesting to keep.
Besides that, a post lives in a certain context (the thread), so we keep the whole thread as well.
Caveats:
* ~~Quotes have a different context. Therefore, when someone quotes a post, it's possible the quoted post will still be deleted.~~ fixed in #379
* Although undocumented (in docs/docs/administration/CLI_tasks/database.md/#prune-old-remote-posts-from-the-database), the 'normal' delete action still kept old remote non-public posts. I added an option to keep this behaviour, but this also means that you now have to explicitly provide that option. **This could be considered a breaking change!**
* ~~Note that this removes from the objects table, but not from the activities.~~ See #427 for that.
Some statistics from explain analyse:
(cost=1402845.92..1933782.00 rows=3810907 width=62) (actual time=2562455.486..2562455.495 rows=0 loops=1)

**TODO**
1. [x] **Question:** Is it OK to keep it like this in regard to quote posts? If not (ie post quoted by local users should also be kept), should we give quotes the same context as the post they are quoting? (If we don't want to give them the same context, I'll have to see how/if I can do it without being too costly)
* See #379
2. [x] **Question:** the "original" query only deletes public posts (this is undocumented, but you can check the code). This new one doesn't care for scope. From the docs I get that the idea is that posts can be refetched when needed. But I have from a trusted source that Pleroma can't refetch non-public posts. I assume that's the reason why they are kept here. I see different options to deal with this
1. ~~We keep it as currently implemented and just don't care about scope with this option~~
2. ~~We add logic to not delete non-public posts either (I'll have to see how costly that becomes)~~
3. We add an extra --keep-non-public parameter. This is technically speaking breakage (you didn't have to provide a param before for this, now you do), but I'm inclined to not care much because it wasn't documented nor tested in the first place.
3. [x] See if we can do the query using Elixir
4. [x] Test on a bigger DB to see that we don't run into a timeout
5. [x] Add docs

Some users post posts with spoofed timestamp, and some clients will have issues with certain dates. Tusky for example crashes if the date is any sooner than 1 BCE (“year zero” in the representation).
I limited the range of what is considered a valid date to be somewhere between the years 1583 and 9999 (inclusive).
The numbers have been chosen because:
- ISO 8601 only allows years before 1583 with “mutual agreement”
- Years after 9999 could cause issues with certain clients as well

When making quotes through Mast-API, they will now have the same context as the quoted post. This also results in them being showed when fetching the thread. I checked Misskey to see how it's there, and they show the quotes there as well, see e.g. <https://mk.toast.cafe/notes/98u1g0tulg>.

Argos Translate is a Python module for translation and can be used as a command line tool.
This is also the engine for LibreTranslate, for which we already have a module.
Here we can use the engine directly from our server without doing requests to a third party or having to install our own LibreTranslate webservice (obviously you do have to install Argos Translate).
One thing that's currently still missing from Argos Translate is auto-detection of languages (see <https://github.com/argosopentech/argos-translate/issues/9>). For now, when no source language is provided, we just return the text unchanged, supposedly translated from the target language. That way you get a near immediate response in pleroma-fe when clicking Translate, after which you can select the source language from a dropdown.
Argos Translate also doesn't seem to handle html very well. Therefore we give admins the option to strip the html before translating. I made this an option because I'm unsure if/how this will change in the future.

this didn't actually _do_ anything in the past,
the users would be prevented from accessing the resource,
but they shouldn't be able to even create them
Until now it was returning a 500 because the upload plug were going
through the changeset and ending in the JSON encoder, which raised
because struct has to @derive the encoder.
Objects who got updated would just pass through several of the MRF policies, undoing moderation in some situations.
In the relevant cases we now check not only for Create activities, but also Update activities.
I checked which ones checked explicitly on type Create using `grep '"type" => "Create"' lib/pleroma/web/activity_pub/mrf/*`.
The following from that list have not been changed:
* lib/pleroma/web/activity_pub/mrf/follow_bot_policy.ex
* Not relevant for moderation
* lib/pleroma/web/activity_pub/mrf/keyword_policy.ex
* Already had a test for Update
* lib/pleroma/web/activity_pub/mrf/object_age_policy.ex
* In practice only relevant when fetching old objects (e.g. through Like or Announce). These are always wrapped in a Create.
* lib/pleroma/web/activity_pub/mrf/reject_non_public.ex
* We don't allow changing scope with Update, so not relevant here
Objects who got updated would just pass the TagPolicy, undoing the moderation that was set in place for the Actor.
Now we check not only for Create activities, but also Update activities.

Only real change here is making MRF rejects log as debug instead of info (#234)
I don't know if it's the best way to do it, but it seems it's just MRF using this and almost always this is intended.
The rest are just minor docs changes and syncing the restricted nicknames stuff.
I compiled and ran my changes with Docker and they all work.

Close#304.
Notes:
- This patch was made on top of Pleroma develop, so I created a separate cachex worker for request signature actions, instead of Akkoma's instance cache. If that is a merge blocker, I can attempt to move logic around for that.
- Regarding the `has_request_signatures: true -> false` state transition: I think that is a higher level thing (resetting instance state on new instance actor key) which is separate from the changes relevant to this one.

- Drop Expect-CT
Expect-CT has been redundant since 2018 when Certificate Transparency became mandated and required for all CAs and browsers. This header is only implemented in Chrome and is now deprecated. HTTP header analysers do not check this anymore as this is enforced by default. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Expect-CT
- Raise HSTS to 2 years and explicitly preload
The longer age for HSTS, the better. Header analysers prefer 2 years over 1 year now as free TLS is very common using Let's Encrypt.
For HSTS to be fully effective, you need to submit your root domain (domain.tld) to https://hstspreload.org. However, a requirement for this is the "preload" directive in Strict-Transport-Security. If you do not have "preload", it will reject your domain.
- Drop X-Download-Options
This is an IE8-era header when Adobe products used to use the IE engine for making outbound web requests to embed webpages in things like Adobe Acrobat (PDFs). Modern apps are using Microsoft Edge WebView2 or Chromium Embedded Framework. No modern browser checks or header analyser check for this.
- Set base-uri to 'none'
This is to specify the domain for relative links (`<base>` HTML tag). pleroma-fe does not use this and it's an incredibly niche tag.
I use all of these myself on my instance by rewriting the headers with zero problems. No breakage observed.
I have not compiled my Elixr changes, but I don't see why they'd break.

The header name was Report-To, not Reply-To.
In any case, that's now being changed to the Reporting-Endpoints HTTP
Response Header.
https://w3c.github.io/reporting/#headerhttps://github.com/w3c/reporting/issues/177
CanIUse says the Report-To header is still supported by current Chrome
and friends.
https://caniuse.com/mdn-http_headers_report-to
It doesn't have any data for the Reporting-Endpoints HTTP header, but
this article says Chrome 96 supports it.
https://web.dev/reporting-api/
(Even though that's come out one year ago, that's not compatible with
Network Error Logging which's still using the Report-To version of the

Simple fix for LDAP user registration. I'm not sure what changed but I managed to get Akkoma running in a debug session and figured out it was missing a match for an extra value at the end. I don't know Elixir all that well so I'm not sure if this was the correct way to do it... but it works. :)

During attachment upload Pleroma returns a "description" field.
* This MR allows Pleroma to read the EXIF data during upload and return the description to the FE using this field.
* If a description is already present (e.g. because a previous module added it), it will use that
* Otherwise it will read from the EXIF data. First it will check -ImageDescription, if that's empty, it will check -iptc:Caption-Abstract
* If no description is found, it will simply return nil, which is the default value
* When people set up a new instance, they will be asked if they want to read metadata and this module will be activated if so
There was an Exiftool module, which has now been renamed to Exiftool.StripLocation
The problem was double. On the one hand, the function didn't actually return what was in the DB.
On the other hand the test was flaky because it used NaiveDateTime.utc_now() so test could fail or pass depending on a difference of microseconds.
Both are fixed now.

As this plug is called on every request, this should reduce load on the
database by not requiring to select on the users table every single
time, and to instead use the by-ID user cache whenever possible.
This fixes a race condition bug where keys could be regenerated
post-federation, causing activities and HTTP signatures from an user to
be dropped due to key differences.
Non-Create/Listen activities had their associated object field
normalized and fetched, but only to use their `id` field, which is both
slow and redundant. This also failed on Undo activities, which delete
the associated object/activity in database.
Undo activities will now render properly and database loads should
improve ever so slightly.

This field replaces the now deprecated conversation_id field, and now
exposes the ActivityPub object `context` directly via the MastoAPI
instead of relying on StatusNet-era data concepts.
This field seems to be a left-over from the StatusNet era.
If your application uses `pleroma.conversation_id`: this field is
deprecated.
It is currently stubbed instead by doing a CRC32 of the context, and
clearing the MSB to avoid overflow exceptions with signed integers on
the different clients using this field (Java/Kotlin code, mostly; see
Husky and probably other mobile clients.)
This should be removed in a future version of Pleroma. Pleroma-FE
currently depends on this field, as well.
Incoming Pleroma replies to a Misskey thread were rejected due to a
broken context fix, which caused them to not be visible until a
non-Pleroma user interacted with the replies.
This fix properly sets the post-fix object context to its parent Create
activity as well, if it was changed.
