The current 10 GiB cache size is too large to fit into tmpfs for VMs and
other machines with smaller RAM sizes. Most non-Debian distros mount
/tmp on tmpfs.
Documentation was already clear on this only stripping GPS tags.
But there are more potentially sensitive metadata tags (e.g. author
and possibly description) and the name alone suggests a broader effect.
Thus change the filter to strip all metadata except for colourspace info
and orientation (technically it strips everything and then readds
selected tags).
Explicitly stripping CommonIFD0 is needed since -all does not modify
IFD0 due to TIFF storing some actual image data there. CommonIFD0 then
strips a bunch of commonly used actual metadata tags from IFD0, to my
understanding leaving TIFF image data and custom metadata tags intact.
As of exiftool 12.57 both formats are supported, but EXIF data is
optional for JXL and if exiftool doesn’t find a preexisting metadata
chunk it will create one and treat it as a minor error resulting in
a non-zero exit code.
Setting -ignoreMinorErrors avoids failing on such uploads.
Due to JSON-LD compaction the full address of public scope
may also occur in shorter forms and the spec requires us to treat them
all equivalently. To save us the pain of repeatedly checking for all
variants internally, normalise inbound data to just one form.
See note at: https://www.w3.org/TR/activitypub/#public-addressing
This needs to happen very early, even before the other addressing fixes
else an earlier validator will reject the object. This in turn required
to move the list-tpye normalisation earlier as well, but since I was
unsure about putting empty lists into the data when no such field
existed before, I excluded this case and thus the later fixing had to be
kept as well.

Alongside moving to certbot's nginx plugin, also use conf.d instead of
recreating the sites-{available,enabled} setup that Debian/Ubuntu uses.
Furthermore, also request a certificate for the media domain at the same
time since that's now required.
The API parameter is not a timestamp but an offset.
If a sufficient amount of time passes between the tests
expires_at calculation and the internal calculation during processing
of the request the strict equality assertion fails. (Either a direct
assertion or indirect via job lookup).
To avoid this lower comparison granularity.
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

: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.
This brings it in line with its documentation and akkoma-fe’s
expectations. For backwards compatibility URL parameters are still
accept with lower priority. Unfortunately this means duplicating
parameters and descriptions in the API spec.
Usually Plug already pre-merges parameters from different sources into
the plain 'params' parameter which then gets forwarded by Phoenix.
However, OpenApiSpex 3.x prevents this; 4.x is set to change this

Per the XRD specification:
> 2.4. Element <Alias>
>
> The <Alias> element contains a URI value that is an additional
> identifier for the resource described by the XRD. This value
> MUST be an absolute URI. The <Alias> element does not identify

(http://docs.oasis-open.org/xri/xrd/v1.0/os/xrd-1.0-os.html#element.alias, emphasis mine)
In other words, the alias list is expected to link to things which are
not just semantically the same, but exactly the same. Old user accounts
don't do that
This change should not pose a compatibility issue: Mastodon does not
list old accounts here (See e1fcb02867/app/serializers/webfinger_serializer.rb (L12))
The use of as:alsoKnownAs is also not quite semantically right here
(see https://www.w3.org/TR/did-core/#dfn-alsoknownas, which defines
it to be used to refer to identifiers which are interchangable) but
that's what DID get for reusing a property definition that Mastodon
already squatted long before they got to it
The newest git HEAD of MIME already knows about APNG, but this

Fixes: akkoma#657
This protects us from falling for obvious spoofs as from the current
upload exploit (unfortunately we can’t reasonably do anything about
spoofs with exact matches as was possible via emoji and proxy).
Such objects being invalid is supported by the spec, sepcifically
sections 3.1 and 3.2: https://www.w3.org/TR/activitypub/#obj-id
Anonymous objects are not relevant here (they can only exists within
parent objects iiuc) and neither is client-to-server or transient objects
(as those cannot be fetched in the first place).
This leaves us with the requirement for `id` to (a) exist and
(b) be a publicly dereferencable URI from the originating server.
This alone does not yet demand strict equivalence, but the spec then
further explains objects ought to be fetchable _via their ID_.
Meaning an object not retrievable via its ID, is invalid.
This reading is supported by the fact, e.g. GoToSocial (recently) and
Mastodon (for 6+ years) do already implement such strict ID checks,
additionally proving this doesn’t cause federation issues in practice.
However, apart from canonical IDs there can also be additional display
URLs. *omas first redirect those to their canonical location, but *keys
and Mastodon directly serve the AP representation without redirects.
Mastodon and GTS deal with this in two different ways,
but both constitute an effective countermeasure:
- Mastodon:
Unless it already is a known AP id, two fetches occur.
The first fetch just reads the `id` property and then refetches from
the id. The last fetch requires the returned id to exactly match the
URL the content was fetched from. (This can be optimised by skipping
the second fetch if it already matches)
05eda8d193/app/helpers/jsonld_helper.rb (L168)63f0979799
- GTS:
Only does a single fetch and then checks if _either_ the id
_or_ url property (which can be an object) match the original fetch
URL. This relies on implementations always including their display URL
as "url" if differing from the id. For actors this is true for all
investigated implementations, for posts only Mastodon includes an
"url", but it is also the only one with a differing display URL.
2bafd7daf5 (diff-943bbb02c8ac74ac5dc5d20807e561dcdfaebdc3b62b10730f643a20ac23c24fR222)
Albeit Mastodon’s refetch offers higher compatibility with theoretical
implmentations using either multiple different display URL or not
denoting any of them as "url" at all, for now we chose to adopt a
GTS-like refetch-free approach to avoid additional implementation
concerns wrt to whether redirects should be allowed when fetching a
canonical AP id and potential for accidentally loosening some checks
(e.g. cross-domain refetches) for one of the fetches.
This may be reconsidered in the future.
Since we always followed redirects (and until recently allowed fuzzy id
matches), the ap_id of the received object might differ from the iniital
fetch url. This lead to us mistakenly trying to insert a new user with
the same nickname, ap_id, etc as an existing user (which will fail due
to uniqueness constraints) instead of updating the existing one.
Since we reject cross-domain redirects, this doesn’t yet
make a difference, but it’s requried for stricter checking
subsequent commits will introduce.
To make sure (and in case we ever decide to reallow
cross-domain redirects) also use the final location
for containment and reachability checks.
In order to properly process incoming notes we need
to be able to map the key id back to an actor.
Also, check collections actually belong to the same server.
Key ids of Hubzilla and Bridgy samples were updated to what
modern versions of those output. If anything still uses the
old format, we would not be able to verify their posts anyway.
If it’s not already in the database,
it must be counterfeit (or just not exists at all)
Changed test URLs were only ever used from "local: false" users anyway.
This brings it in line with its name and closes an,
in practice harmless, verification hole.
This was/is the only user of contain_origin making it
safe to change the behaviour on actor-less objects.
Until now refetched objects did not ensure the new actor matches the
domain of the object. We refetch polls occasionally to retrieve
up-to-date vote counts. A malicious AP server could have switched out
the poll after initial posting with a completely different post
attribute to an actor from another server.
While we indeed fell for this spoof before the commit,
it fortunately seems to have had no ill effect in practice,
since the asociated Create activity is not changed. When exposing the
actor via our REST API, we read this info from the activity not the
object.
This at first thought still keeps one avenue for exploit open though:
the updated actor can be from our own domain and a third server be
instructed to fetch the object from us. However this is foiled by an
id mismatch. By necessity of being fetchable and our longstanding
same-domain check, the id must still be from the attacker’s server.
Even the most barebone authenticity check is able to sus this out.
Such redirects on AP queries seem most likely to be a spoofing attempt.
If the object is legit, the id should match the final domain anyway and
users can directly use the canonical URL.
The lack of such a check (and use of the initially queried domain’s
authority instead of the final domain) was enabling the current exploit
to even affect instances which already migrated away from a same-domain
upload/proxy setup in the past, but retained a redirect to not break old
attachments.
(In theory this redirect could, with some effort, have been limited to
only old files, but common guides employed a catch-all redirect, which
allows even future uploads to be reachable via an initial query to the
main domain)
Same-domain redirects are valid and also used by ourselves,
e.g. for redirecting /notice/XXX to /objects/YYY.
Turns out we already had a test for activities spoofed via upload due
to an exploit several years. Back then *oma did not verify content-type
at all and doing so was the only adopted countermeasure.
Even the added test sample though suffered from a mismatching id, yet
nobody seems to have thought it a good idea to tighten id checks, huh
Since we will add stricter id checks later, make id and URL match
and also add a testcase for no content type at all. The new section
will be expanded in subsequent commits.
No new path traversal attacks are known. But given the many entrypoints
and code flow complexity inside pack.ex, it unfortunately seems
possible a future refactor or addition might reintroduce one.
Furthermore, some old packs might still contain traversing path entries
which could trigger undesireable actions on rename or delete.
To ensure this can never happen, assert safety during path construction.
Path.safe_relative was introduced in Elixir 1.14, but
fortunately, we already require at least 1.14 anyway.
To save on bandwith and avoid OOMs with large files.
Ofc, this relies on the remote server
(a) sending a content-length header and
(b) being honest about the size.
Common fedi servers seem to provide the header and (b) at least raises
the required privilege of an malicious actor to a server infrastructure
admin of an explicitly allowed host.
A more complete defense which still works when faced with
a malicious server requires changes in upstream Finch;
see https://github.com/sneako/finch/issues/224
Certain attacks rely on predictable paths for their payloads.
If we weren’t so overly lax in our (id, URL) check, the current
counterfeit activity exploit would be one of those.
It seems plausible for future attacks to hinge on
or being made easier by predictable paths too.
In general, letting remote actors place arbitrary data at
a path within our domain of their choosing (sans prefix)
just doesn’t seem like a good idea.
Using fully random filenames would have worked as well, but this
is less friendly for admins checking emoji dirs.
The generated suffix should still be more than enough;
an attacker needs on average 140 trillion attempts to
correctly guess the final path.
This will decouple filenames from shortcodes and
allow more image formats to work instead of only
those included in the auto-load glob. (Albeit we
still saved other formats to disk, wasting space)
Furthermore, this will allow us to make
final URL paths infeasible to predict.
Since 3 commits ago we restrict shortcodes to a subset of
the POSIX Portable Filename Character Set, therefore
this can never have a directory component.
E.g. *key’s emoji URLs typically don’t have file extensions, but
until now we just slapped ".png" at its end hoping for the best.
Furthermore, this gives us a chance to actually reject non-images,
which before was not feasible exatly due to those extension-less URLs
As suggested in b387f4a1c1, only steal
emoji with alphanumerc, dash, or underscore characters.
Also consolidate all validation logic into a single function.
===
Taken from akkoma#703 with cosmetic tweaks
This matches our existing validation logic from Pleroma.Emoji,
and apart from excluding the dot also POSIX’s Portable Filename
Character Set making it always safe for use in filenames.
Mastodon is even stricter also disallowing U+002D HYPEN-MINUS
and requiring at least two characters.
Given both we and Mastodon reject shortcodes excluded
by this anyway, this doesn’t seem like a loss.
Even more than with user uploads, a same-domain proxy setup bears
significant security risks due to serving untrusted content under
the main domain space.
A risky setup like that should never be the default.
Just as with uploads and emoji before, this can otherwise be used
to place counterfeit AP objects or other malicious payloads.
In this case, even if we never assign a priviliged type to content,
the remote server can and until now we just mimcked whatever it told us.
Preview URLs already handle only specific, safe content types
and redirect to the external host for all else; thus no additional
sanitisiation is needed for them.
Non-previews are all delegated to the modified ReverseProxy module.
It already has consolidated logic for building response headers
making it easy to slip in sanitisation.
Although proxy urls are prefixed by a MAC built from a server secret,
attackers can still achieve a perfect id match when they are able to
change the contents of the pointed to URL. After sending an posts
containing an attachment at a controlled destination, the proxy URL can
be read back and inserted into the payload. After injection of
counterfeits in the target server the content can again be changed
to something innocuous lessening chance of detection.
By mapping all extensions related to our custom privileged types
back to innocuous text/plain, our custom types will never automatically
be inserted which was one of the factors making impersonation possible.
Note, this does not invalidate the upload and emoji Content-Type
restrictions from previous commits. Apart from counterfeit AP objects
there are other payloads with standard types this protects against,
e.g. *.js Javascript payloads as used in prior frontend injections.
Else malicious emoji packs or our EmojiStealer MRF can
put payloads into the same domain as the instance itself.
Sanitising the content type should prevent proper clients
from acting on any potential payload.
Note, this does not affect the default emoji shipped with Akkoma
as they are handled by another plug. However, those are fully trusted
and thus not in needed of sanitisation.
This actually was already intended before to eradict all future
path-traversal-style exploits and to fix issues with some
characters like akkoma#610 in 0b2ec0ccee. However, Dedupe and
AnonymizeFilename got mixed up. The latter only anonymises the name
in Content-Disposition headers GET parameters (with link_name),
_not_ the upload path.
Even without Dedupe, the upload path is prefixed by an UUID,
so it _should_ already be hard to guess for attackers. But now
we actually can be sure no path shenanigangs occur, uploads
reliably work and save some disk space.
While this makes the final path predictable, this prediction is
not exploitable. Insertion of a back-reference to the upload
itself requires pulling off a successfull preimage attack against
SHA-256, which is deemed infeasible for the foreseeable futures.
Dedupe was already included in the default list in config.exs
since 28cfb2c37a, but this will get overridde by whatever the
config generated by the "pleroma.instance gen" task chose.
Upload+delete tests running in parallel using Dedupe might be flaky, but
this was already true before and needs its own commit to fix eventually.
The lack thereof enables spoofing ActivityPub objects.
A malicious user could upload fake activities as attachments
and (if having access to remote search) trick local and remote
fedi instances into fetching and processing it as a valid object.
If uploads are hosted on the same domain as the instance itself,
it is possible for anyone with upload access to impersonate(!)
other users of the same instance.
If uploads are exclusively hosted on a different domain, even the most
basic check of domain of the object id and fetch url matching should
prevent impersonation. However, it may still be possible to trick
servers into accepting bogus users on the upload (sub)domain and bogus
notes attributed to such users.
Instances which later migrated to a different domain and have a
permissive redirect rule in place can still be vulnerable.
If — like Akkoma — the fetching server is overly permissive with
redirects, impersonation still works.
This was possible because Plug.Static also uses our custom
MIME type mappings used for actually authentic AP objects.
Provided external storage providers don’t somehow return ActivityStream
Content-Types on their own, instances using those are also safe against
their users being spoofed via uploads.
Akkoma instances using the OnlyMedia upload filter
cannot be exploited as a vector in this way — IF the
fetching server validates the Content-Type of
fetched objects (Akkoma itself does this already).
However, restricting uploads to only multimedia files may be a bit too
heavy-handed. Instead this commit will restrict the returned
Content-Type headers for user uploaded files to a safe subset, falling
back to generic 'application/octet-stream' for anything else.
This will also protect against non-AP payloads as e.g. used in
past frontend code injection attacks.
It’s a slight regression in user comfort, if say PDFs are uploaded,
but this trade-off seems fairly acceptable.
(Note, just excluding our own custom types would offer no protection
against non-AP payloads and bear a (perhaps small) risk of a silent
regression should MIME ever decide to add a canonical extension for
ActivityPub objects)
Now, one might expect there to be other defence mechanisms
besides Content-Type preventing counterfeits from being accepted,
like e.g. validation of the queried URL and AP ID matching.
Inserting a self-reference into our uploads is hard, but unfortunately
*oma does not verify the id in such a way and happily accepts _anything_
from the same domain (without even considering redirects).
E.g. Sharkey (and possibly other *keys) seem to attempt to guard
against this by immediately refetching the object from its ID, but
this is easily circumvented by just uploading two payloads with the
ID of one linking to the other.
Unfortunately *oma is thus _both_ a vector for spoofing and
vulnerable to those spoof payloads, resulting in an easy way
to impersonate our users.
Similar flaws exists for emoji and media proxy.
Subsequent commits will fix this by rigorously sanitising
content types in more areas, hardening our checks, improving
the default config and discouraging insecure config options.
The default refresh interval of 1 day is woefully inadequate here;
users expect to be able to add the alias to their new account and
press the move button on their old account and have it work.
This allows callers to specify a maximum age before a refetch is
triggered. We set that to 5s for the move code, as a nice compromise
between Making Things Work and ensuring that this can't be used
to hammer a remote server

This will crop them to a square matching behaviour of Husky and *key
and allowing us to never worry about consistent alignment.
Note, akkoma-fe instead displays the full image with inserted spacing.
Mastodon at the very least seems to prevent the creation of emoji with
dots in their name (and refuses to accept them in federation). It feels
like being cautious in what we accept is reasonable here.
Colons are the emoji separator and so obviously should be blocked.
Perhaps instead of filtering out things like this we should just
do a regex match on `[a-zA-Z0-9_-]`? But that's plausibly a decision
for another day
Perhaps we should also have a centralised "is this a valid emoji shortcode?"

This partly reverts 1d884fd914
while fixing both the issue it addressed and the issue it caused.
The above commit successfully fixed OpenGraph metadata tags
which until then always showed the user bio instead of post content
by handing the activities AP ID as url to the Metadata builder
_instead_ of passing the internal ID as activity_id.
However, in doing so the commit instead inflicted this very problem
onto Twitter metadata tags which ironically are used by akkoma-fe.
This is because while the OpenGraph builder wants an URL as url,
the Twitter builder needs the internal ID to build the URL to the
embedded player for videos and has no URL property.
Thanks to twpol for tracking down this root cause in #644.
Now, once identified the problem is simple, but this simplicity
invites multiple possible solutions to bikeshed about.
1. Just pass both properties to the builder and let them pick
2. Drop the url parameter from the OpenGraph builder and instead
a) build static-fe URL of the post from the ID (like Twitter)
b) use the passed-in object’s AP ID as an URL
Approach 2a has the disadvantage of hardcoding the expected URL outside
the router, which will be problematic should it ever change.
Approach 2b is conceptually similar to how the builder works atm.
However, the og:url is supposed to be a _permanent_ ID, by changing it
we might, afaiui, technically violate OpenGraph specs(?). (Though its
real-world consequence may very well be near non-existent.)
This leaves just approach 1, which this commit implements.
Albeit it too is not without nits to pick, as it leaves the metadata
builders with an inconsistent interface.
Additionally, this will resolve the subotpimal Discord previews for
content-less image posts reported in #664.
Discord already prefers OpenGraph metadata, so it’s mostly unaffected.
However, it appears when encountering an explicitly empty OpenGraph
description and a non-empty Twitter description, it replaces just the
empty field with its Twitter counterpart, resulting in the user’s bio
slipping into the preview.
Secondly, regardless of any OpenGraph tags, Discord uses twitter:card to
decide how prominently images should be, but due to the bug the card
type was stuck as "summary", forcing images to always remain small.

fixed up some grammer / wording. removed a setence and made wording more in line with what I could find in Admin-FE (especially wording of "rejecting" vs. dropping)
This vastly reduces idle CPU usage, which should generally be beneficial
for most small-to-medium sized instances.
Additionally update the documentation to specify how to override the vm.args
file for OTP installs
This fixes an oversight in e99e2407f3
which added background_removal as a possible SimplePolicy setting.
However, it did _not_ add a default value to the base config and
as it turns out instance_list doesn’t handle unset options well.
In effect this caused federating instances with SimplePolicy enabled
but background_removal not explicitly configured to always trip up for
outgoing account updates in check_background_removal (and incoming
updates from Sharkey).
For added ""fun"" this error was able to block account updates made
e.g. via /api/v1/accounts/update_credentials.
Tests were unaffected since they explicitly override
all relevant config options.
Set a default to avoid all this
(note to self: don’t forget next time, baka!)
Currently our own frontend doesn’t show backgrounds of other users, this
property is already publicly readable via REST API and likely was always
intended to be shown and federated.
Recently Sharkey added support for profile backgrounds and
immediately made them federate and be displayed to others.
We use the same AP field as Sharkey here which should make
it interoperable both ways out-of-the-box.
Ref.: 4e64397635
Fixes misspelling and omission of and example in commit
0cfd5b4e89 which added the
status_ttl_property. This was the only place this commit
referred to the property as note_ttl_days.
Partially fixes the omitted schema update of the instance metadata addition
from commit b7e8ce2350. A proper full schema
for nodeinfo is still missing.
OTP’s default SSL/TLS settings are rather restricitive
and in particular do not use system CA certs.
In our case using system CA certs is virtually always desired
and the lack of it leads to non-obvious errors. Manually configuring
system CA certs from in-database config also isn’t straightforward.
Furthermore, gen_smtp uses a different set of connection options
for direct SSL/TLS and a later TLS upgrade providing additional
confusion and complexity in how to configure this.
Thus provide some suitable defaults for sending SMTP emails.
Everything can still be overriden by admins if necessary.
Note: defaults are not appended when validating the config
in hopes of improving the error message (as the required relay key
is already accessed to generate defaults for optional fields)
Fixes: #660
With kilobyte the resulting numbers got too large and were cut off
in the charts, making them useless. However, even an idle Akkoma
server’s memory usage is in the lower hundreths of megabytes, so
we don’t need this much precision to begin with for the dashboard.
Other metric users might prefer base units and can handle scaling in a
smarter way, so keep this configurable.
The spec was copied from another endpoint, including the operation id,
leading to scrubbing the valid parameters from the request and simply
not working.
the previous code passed a state parameter to ueberauth with info
about where to go after the user logged in, etc.
since ueberauth 0.7, this parameter is ignored and oauth state is used
for actual CSRF reasons.
we now set a cookie with the state we need to keep track of, and read
it once the callback happens.
Implements the preferences endpoint in the Mastodon API, but returns
default values for most of the preferences right now. The only supported
preference we can access is default post visibility, and a relevant test
is added as well.
Currently, Akkoma sorts by published date first before everything else.
This however makes search results pretty bad since Meilisearch uses a
bucket sort algorithm in order of the ranking rules specified:
https://www.meilisearch.com/docs/learn/core_concepts/relevancy#behavior
Since the `published` attribute is a unix timestamp, the resulting
buckets are pretty small so the other rules essentially have little to
no effect on the rankings of search results.
This fixes that issue by moving the `published:desc` rule further down
so it still sorts by date, but only after considering everything else.
AFAIK attribute and sort doesn't really affect results for Akkoma since
the only attribute considered is the `content` attribute and the `sort`
parameter isn't used in Akkoma searches. Everything else is made to
match more closely to Meilisearch's defaults.
The docker-compose.yml file is likely to be edited quite extensively by
admins when setting up an instance. This would likely cause problems
when dealing with updating Akkoma as merge conflicts would likely occur.
Docker-compose already has the ability to use override files in addition
to the main `docker-compose.yml` file. Admins can instead put any
overrides (additional volumes, container for elasticsearch, etc.) into a
file that won't be tracked by git and thus won't run into merge
conflicts in the future. In particular, the
`docker-compose.override.yml` will be checked by docker compose in
addition to the main file if it exists and override definitions from the
latter with the former.

We also had one case of someone who got errors because the SHELL variable wasn't set. This is the case for Alpine.
Here I added a line to fill it in when not set.

Commit 11ec9daa5b (released with 3.2.0)
added the fedibird frontend and tweaked and extended Mastodon API for
compatibility with it. Document these changes.
Set it to `inline` because the vast majority of what's sent is multimedia
content while `attachment` would have the side-effect of triggering a
download dialog.
Closes: https://git.pleroma.social/pleroma/pleroma/-/issues/3114
TwitterCard meta tags are supposed to use the attributes "name" and "content".
OpenGraph tags use the attributes "property" and "content".
Twitter itself is smart enough to detect broken meta tags and discover the TwitterCard
using "property" and "content", but other platforms that only implement parsing of TwitterCards
and not OpenGraph may fail to correctly detect the tags as they're under the wrong attributes.
> "Open Graph protocol also specifies the use of property and content attributes for markup while
> Twitter cards use name and content. Twitter’s parser will fall back to using property and content,
> so there is no need to modify existing Open Graph protocol markup if it already exists." [0]

`context` fields for objects and activities can now be generated based
on the object/activity `inReplyTo` field or its ActivityPub ID, as a
fallback method in cases where `context` fields are missing for incoming

A recent group of vulnerabilities have been found in Pleroma (and
inherited by Akkoma) that involve media files either uploaded by local
users or proxied from remote instances (if media proxy is enabled).
It is recommended that media files are served on a separate subdomain
in order to mitigate this class of vulnerabilities.

When doing prune_objects, it's possible that bookmarked objects are deleted.

This make the behavior consistent between when UserNote doesn't exist and when comment is null.
The current behavior may return null in APIs, which misleads some clients doing feature detection into thinking the server does not support comments.

When no image description is filled in, Pleroma allowed fallbacks.
Those were (based on a setting) either the filename, or a fixed description.
Neither are good options for image descriptions imo, so here we remove this.
Note that there's two tests removed who supposedly tested something else.
But examining closer, they didn't seem to test what they claimed to test,
so I removed them rather than try to "fix" them.

Expose quote posting in the api as a feature.
Copies what the quote post PR for pleroma does to allow external clients to enable and disable features based on the feature-set of the instance.
As far as I am aware, akkoma doesn't allow you to disable quote posting, so this doesn't need anything fancy and it's just a hard on switch.
I tried to get one for the bubble tl to work also, but I'm not quite sure how to do it so that it switches off the feature when the bubble tl is disabled. I would argue that it could and ideally should be done as well though.
I also discovered a pretty tame bug in the testing of it, that deleting the DB entry for the bubble tl does not stop the bubble TL from actually working and it will continue to display the panel on the about page, I'll just leave it as a note here.

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.
By default Postgresql first restores the data and then the indexes when dumping and restoring the database.
Restoring index activities_visibility_index took a very long time.
users_ap_id_COALESCE_follower_address_index was later added because having this could speed up the restoration tremendously.
The problem now is that restoration apparently happens in alphabetical order, so this new index wasn't created yet
by the time activities_visibility_index needed it.
There were several work-arounds which included more complex steps during backup/restore.
By renaming this index, it should be restored first and thus activities_visibility_index can make use of it.
This speeds up restoration significantly without requiring more complex or unexpected steps from people.

I added info about installing front ends from the development branch
I also rearanged the list of exceptions (what's different than "normal" installation)
so the order is closer to how you'd encounter things in the installation docs + small fixes
This should help mitigate negative impacts related to block-retaliation
and block-circumvention when blocks become visible to the blocked party.
Instances interested in broadcasting blocks can turn this on if they
wish. This should have always been the default.

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)

Execution Time: 3287933.902 ms
***
**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

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.

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.
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

691 changed files with 138417 additions and 14337 deletions
@ -4,6 +4,239 @@ All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
## Unreleased
## Added
- Support for [FEP-fffd](https://codeberg.org/fediverse/fep/src/branch/main/fep/fffd/fep-fffd.md) (proxy objects)
- Verified support for elixir 1.16
- Uploadfilter `Pleroma.Upload.Filter.Exiftool.ReadDescription` returns description values to the FE so they can pre fill the image description field
NOTE: this filter MUST be placed before `Exiftool.StripMetadata` to work
## Changed
- Inbound pipeline error handing was modified somewhat, which should lead to less incomprehensible log spam. Hopefully.
- Uploadfilter `Pleroma.Upload.Filter.Exiftool` was replaced by `Pleroma.Upload.Filter.Exiftool.StripMetadata`;
the latter strips all non-essential metadata by default but can be configured.
To regain the old behaviour of only stripping GPS data set `purge: ["gps:all"]`.
- Uploadfilter `Pleroma.Upload.Filter.Exiftool` has been renamed to `Pleroma.Upload.Filter.Exiftool.StripMetadata`
- MRF.InlineQuotePolicy now prefers to insert display URLs instead of ActivityPub IDs
- Old accounts are no longer listed in WebFinger as aliases; this was breaking spec
## Fixed
- Issue preventing fetching anything from IPv6-only instances
- Issue allowing post content to leak via opengraph tags despite :estrict\_unauthenticated being set
- Move activities no longer operate on stale user data
- Missing definitions in our JSON-LD context
- Issue mangling newlines in code blocks for RSS/Atom feeds
- static\_fe squeezing non-square avatars and emoji
- Issue leading to properly JSON-LD compacted emoji reactions being rejected
- We now use a standard-compliant Accept header when fetching ActivityPub objects
- /api/pleroma/notification\_settings was rejecting body parameters;
this also broke changing this setting via akkoma-fe
- Issue leading to Mastodon bot accounts being rejected
- Scope misdetection of remote posts resulting from not recognising
JSON-LD-compacted forms of public scope; affected e.g. federation with bovine
## Removed
- ActivityPub Client-To-Server write API endpoints have been disabled;
read endpoints are planned to be removed next release unless a clear need is demonstrated
## 2024.03
## Added
- CLI tasks best-effort checking for past abuse of the recent spoofing exploit
- new `:mrf_steal_emoji, :download_unknown_size` option; defaults to `false`
## Changed
- `Pleroma.Upload, :base_url` now MUST be configured explicitly if used;
use of the same domain as the instance is **strongly** discouraged
- `:media_proxy, :base_url` now MUST be configured explicitly if used;
use of the same domain as the instance is **strongly** discouraged
- StealEmoji:
- now uses the pack.json format;
existing users must migrate with an out-of-band script (check release notes)
- only steals shortcodes recognised as valid
- URLs of stolen emoji is no longer predictable
- The `Dedupe` upload filter is now always active;
`AnonymizeFilenames` is again opt-in
- received AP data is sanity checked before we attempt to parse it as a user
- Uploads, emoji and media proxy now restrict Content-Type headers to a safe subset
- Akkoma will no longer fetch and parse objects hosted on the same domain
## Fixed
- Critical security issue allowing Akkoma to be used as a vector for
(depending on configuration) impersonation of other users or creation
of bogus users and posts on the upload domain
- Critical security issue letting Akkoma fall for the above impersonation
payloads due to lack of strict id checking
- Critical security issue allowing domains redirect to to pose as the initial domain
(e.g. with media proxy's fallback redirects)
- refetched objects can no longer attribute themselves to third-party actors
(this had no externally visible effect since actor info is read from the Create activity)
- our litepub JSON-LD schema is now served with the correct content type
- remote APNG attachments are now recognised as images
## Upgrade Notes
- As mentioned in "Changed", `Pleroma.Upload, :base_url`**MUST** be configured. Uploads will fail without it.
- Akkoma will refuse to start if this is not set.
- Same with media proxy.
## 2024.02
## Added
- Full compatibility with Erlang OTP26
- handling of GET /api/v1/preferences
- Akkoma API is now documented
- ability to auto-approve follow requests from users you are already following
- The SimplePolicy MRF can now strip user backgrounds from selected remote hosts
## Changed
- OTP builds are now built on erlang OTP26
- The base Phoenix framework is now updated to 1.7
- An `outbox` field has been added to actor profiles to comply with AP spec
- User profile backgrounds do now federate with other Akkoma instances and Sharkey
## Fixed
- Documentation issue in which a non-existing nginx file was referenced
- Issue where a bad inbox URL could break federation
- Issue where hashtag rel values would be scrubbed
- Issue where short domains listed in `transparency_obfuscate_domains` were not actually obfuscated
## 2023.08
## Added
- Added a new configuration option to the MediaProxy feature that allows the blocking of specific domains from using the media proxy or being explicitly allowed by the Content-Security-Policy.
- Please make sure instances you wanted to block media from are not in the MediaProxy `whitelist`, and instead use `blocklist`.
- `OnlyMedia` Upload Filter to simplify restricting uploads to audio, image, and video types
- ARM64 OTP builds
- Ubuntu22 builds are available for develop and stable
- other distributions are stable only
- Support for Elixir 1.15
- 1.14 is still supported
- OTP26 is currently "unsupported". It will probably work, but due to the way
it handles map ordering, the test suite will not pass for it as yet.
## Changed
- Alpine OTP builds are now from alpine 3.18, which is OpenSSLv3 compatible.
If you use alpine OTP builds you will have to update your local system.
- Debian OTP builds are now from a base of bookworm, which is OpenSSLv3 compatible.
If you use debian OTP builds you will have to update your local system to
bookworm (currently: stable).
- Ubuntu and debian builds are compatible again! (for now...)
- Blocks/Mutes now return from max ID to min ID, in line with mastodon.
- The AnonymizeFilename filter is now enabled by default.
## Fixed
- Deactivated users can no longer show up in the emoji reaction list
- Embedded posts can no longer bypass `:restrict\_unauthenticated`
- GET/HEAD requests will now work when requesting AWS-based instances.
## Security
- Add `no_new_privs` hardening to OpenRC and systemd service files
- XML parsers cannot load any entities (thanks @Mae@is.badat.dev!)
- Reduced permissions of config files and directories, distros requiring greater permissions like group-read need to pre-create the directories
## Removed
- Builds for debian oldstable (bullseye)
- If you are on oldstable you should NOT attempt to update OTP builds without
first updating your machine.
## 2023.05
## Added
- Custom options for users to accept/reject private messages
- options: everybody, nobody, people\_i\_follow
- MRF to reject notes from accounts newer than a given age
- this will have the side-effect of rejecting legitimate messages if your
post gets boosted outside of your local bubble and people your instance
does not know about reply to it.
## Fixed
- Support for `streams` public key URIs
- Bookmarks are cleaned up on DB prune now
## Security
- Fixed mediaproxy being a bit of a silly billy
## 2023.04
## Added
- Nodeinfo keys for unauthenticated timeline visibility
- Option to disable federated timeline
- Option to make the bubble timeline publicly accessible
- Ability to swap between installed standard frontends
- *mastodon frontends are still not counted as standard frontends due to the complexity in serving them correctly*.
### Upgrade Notes
- Elixir 1.14 is now required. If your distribution does not package this, you can
use [asdf](https://asdf-vm.com/). At time of writing, elixir 1.14.3 / erlang 25.3
is confirmed to work.
## 2023.03
## Fixed
- Allowed contentMap to be updated on edit
- Filter creation now accepts expires\_at
### Changed
- Restoring the database from a dump now goes much faster without need for work-arounds
- Misskey reaction matching uses `content` parameter now
### Added
- Extend the mix task `prune_objects` with option `--prune-orphaned-activities` to also prune orphaned activities, allowing to reclaim even more database space
### Removed
- Possibility of using the `style` parameter on `span` elements. This will break certain MFM parameters.
- Option for "default" image description.
## 2023.02
### Added
- Prometheus metrics exporting from `/api/v1/akkoma/metrics`
- Ability to alter http pool size
- Translation of statuses via ArgosTranslate
- Argon2 password hashing
- Ability to "verify" links in profile fields via rel=me
- Mix tasks to dump/load config to/from json for bulk editing
- Followed hashtag list at /api/v1/followed\_tags, API parity with mastodon
- Ability to set posting language in the post form, API parity with mastodon
- Ability to match domains in MRF by a trailing wildcard

You don't need to build and test the docs as long as you make sure the syntax is correct. But in case you do want to build the docs, feel free to do so.
You'll need to install mkdocs for which you can check the [mkdocs installation guide](https://www.mkdocs.org/#installation). Generally it's best to install it using `pip`. You'll also need to install the correct dependencies.
```sh
# Make sure you're in the same directory as this README
# From the root of the Akkoma repo, you'll need to do
cd docs
### Example using a Debian based distro
# Optionally use a virtual environment
python3 -m venv venv
source venv/bin/activate
#### 1. Install pipenv and dependencies
# Install dependencies
pip install -r requirements.txt
```shell
pip install pipenv
pipenv sync
# Run an http server who rebuilds when files change
# Accessable on http://127.0.0.1:8000
mkdocs serve
# Build the docs
# The static html pages will have been created in the folder "site"
# You can serve them from a server by pointing your server software (nginx, apache...) to this location
mkdocs build
# To get out of the virtual environment, you do
deactivate
```
#### 2. (Optional) Activate the virtual environment
Since dependencies are installed in a virtual environment, you can't use them directly. To use them you should either prefix the command with `pipenv run`, or activate the virtual environment for current shell by executing `pipenv shell` once.
#### 3. Build the docs using the script
```shell
[pipenv run] make all
```
#### 4. Serve the files
A folder `site` containing the static html pages will have been created. You can serve them from a server by pointing your server software (nginx, apache...) to this location. During development, you can run locally with
```shell
[pipenv run] mkdocs serve
```
This handles setting up an http server and rebuilding when files change. You can then access the docs on <http://127.0.0.1:8000>

!!! note
The disk space will only be reclaimed after a proper vacuum. By default Postgresql does this for you on a regular basis, but if your instance has been running for a long time and there are many rows deleted, it may be advantageous to use `VACUUM FULL` (e.g. by using the `--vacuum` option).

The disk space will only be reclaimed after `VACUUM FULL`. You may run out of disk space during the execution of the task or vacuuming if you don't have about 1/3rds of the database size free.

### Options
- `--vacuum` - run `VACUUM FULL` after the objects are pruned
- `--keep-threads` - Don't prune posts when they are part of a thread where at least one post has seen local interaction (e.g. one of the posts is a local post, or is favourited by a local user, or has been repeated by a local user...). It also wont delete posts when at least one of the posts in that thread is kept (e.g. because one of the posts has seen recent activity).
- `--keep-non-public` - Keep non-public posts like DM's and followers-only, even if they are remote.

## Vacuum the database
!!! note
By default Postgresql has an autovacuum deamon running. While the tasks described here can help in some cases, they shouldn't be needed on a regular basis. See [the Postgresql docs on vacuuming](https://www.postgresql.org/docs/current/sql-vacuum.html) for more information on this.
### Analyze
Running an `analyze` vacuum job can improve performance by updating statistics used by the query planner. **It is safe to cancel this.**
This will download the latest build for the pre-configured `ref` and install it. It can then be configured as the one of the served frontends in the config file (see `primary` or `admin`).

You can override any of the details. To install an Akkoma-FE build from a different URL, you could do this:
6. Restore the database schema and akkoma role using either of the following options
* You can use the original `setup_db.psql` if you have it[²]: `sudo -Hu postgres psql -f config/setup_db.psql`.
* Or recreate the database and user yourself (replace the password with the one you find in the config file) `sudo -Hu postgres psql -c "CREATE USER akkoma WITH ENCRYPTED PASSWORD '<database-password-wich-you-can-find-in-your-config-file>'; CREATE DATABASE akkoma OWNER akkoma;"`.
7. Now restore the Akkoma instance's data into the empty database schema[¹][³]: `sudo -Hu postgres pg_restore -d akkoma -v -1 </path/to/backup_location/akkoma.pgdump>`
8. If you installed a newer Akkoma version, you should run `MIX_ENV=prod mix ecto.migrate`[⁴]. This task performs database migrations, if there were any.
7. Now restore the Akkoma instance's data into the empty database schema[¹]: `sudo -Hu postgres pg_restore -d akkoma -v -1 </path/to/backup_location/akkoma.pgdump>`
8. If you installed a newer Akkoma version, you should run `MIX_ENV=prod mix ecto.migrate`[³]. This task performs database migrations, if there were any.
9. Restart the Akkoma service.
10. Run `sudo -Hu postgres vacuumdb --all --analyze-in-stages`. This will quickly generate the statistics so that postgres can properly plan queries.
11. If setting up on a new server configure Nginx by using the `installation/akkoma.nginx` config sample or reference the Akkoma installation guide for your OS which contains the Nginx configuration instructions.
[¹]: We assume the database name and user are both "akkoma". If not, you can find the correct name in your config files.
[²]: You can recreate the `config/setup_db.psql` by running the `mix pleroma.instance gen` task again. You can ignore most of the questions, but make the database user, name, and password the same as found in your backed up config file. This will also create a new `config/generated_config.exs` file which you may delete as it is not needed.
[³]: `pg_restore` will add data before adding indexes. The indexes are added in alphabetical order. There's one index, `activities_visibility_index` which may take a long time because it can't make use of an index that's only added later. You can significantly speed up restoration by skipping this index and add it afterwards. For that, you can do the following (we assume the akkoma.pgdump is in the directory you're running the commands):
```sh
pg_restore -l akkoma.pgdump > db.list
# Comment out the step for creating activities_visibility_index by adding a semi colon at the start of the line
sed -i -E 's/(.*activities_visibility_index.*)/;\1/' db.list
# We restore the database using the db.list list-file
8. Remove the dependencies that you don't need anymore (see installation guide). Make sure you don't remove packages that are still needed for other software that you have running!
[¹]: We assume the database name and user are both "akkoma". If not, you can find the correct name in your config files.
## Docker installations
If running behind Docker, it is required to run the above commands inside of a running database container.
### Example
Running `docker compose run --rm db pg_dump <...>` will fail and return:
```
pg_dump: error: connection to server on socket "/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?"
```
However, first starting just the database container with `docker compose up db -d`, and then running `docker compose exec db pg_dump -d akkoma --format=custom -f </your/backup/dir/akkoma.pgdump>` will successfully generate a database dump.
Then to make the file accessible on the host system you can run `docker compose cp db:</your/backup/dir/akkoma.pgdump> </your/target/location>` to copy if from the container.
You should **always check the [release notes/changelog](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/CHANGELOG.md)** in case there are config deprecations, special update steps, etc.
You should **always check the [release notes/changelog](https://akkoma.dev/AkkomaGang/akkoma/src/branch/stable/CHANGELOG.md)** in case there are config deprecations, special update steps, etc.
Besides that, doing the following is generally enough:
## Switch to the akkoma user
```sh
# Using sudo
sudo -su akkoma
# Using doas
doas -su akkoma
# Using su
su -s "$SHELL" akkoma
```
## For OTP installations
```sh
# Download the new release
su akkoma -s $SHELL -lc "./bin/pleroma_ctl update"
# Download latest stable release
./bin/pleroma_ctl update --branch stable
# Migrate the database, you are advised to stop the instance before doing that
su akkoma -s $SHELL -lc "./bin/pleroma_ctl migrate"
# Stop akkoma
./bin/pleroma stop # or using the system service manager (e.g. systemctl stop akkoma)
# Run database migrations
./bin/pleroma_ctl migrate
# Start akkoma
./bin/pleroma daemon # or using the system service manager (e.g. systemctl start akkoma)
# Update frontend(s). See Frontend Configuration doc for more information.
[^1]: Depending on which install guide you followed (for example on Debian/Ubuntu), you want to run `git` and `mix` tasks as `akkoma` user by adding `sudo -Hu akkoma` before the command.
[^2]: Prefix with `MIX_ENV=prod` to run it using the production config file.

## Stealing emoji
Managing your emoji can be hard work, and you just want to have the cool emoji your friends use? As usual, crime comes to the rescue!
You can use the `Pleroma.Web.ActivityPub.MRF.StealEmojiPolicy` [Message Rewrite Facility](../configuration/cheatsheet.md#mrf) to automatically add to your instance emoji that messages from specific servers contain. Note that this happens on message processing, so the emoji will be added only after your instance receives some interaction containing emoji _after_ configuring this.
To activate this you have to [configure](../configuration/cheatsheet.md#mrf_steal_emoji) it in your configuration file. For example if you wanted to steal any emoji that is not related to cinnamon and not larger than about 10K from `coolemoji.space` and `spiceenthusiasts.biz`, you would add the following:
```elixir
config :pleroma, :mrf,

# Contributing to Akkoma
You wish to add a new feature in Akkoma, but don't know how to proceed? This guide takes you through the various steps of the development and contribution process.
If you're looking for stuff to implement or fix, check the [bug-tracker](https://akkoma.dev/AkkomaGang/akkoma/issues) or [forum](https://meta.akkoma.dev/c/requests/5).
Come say hi to us in the [#akkoma-dev chat room](./../#irc)!
## Akkoma Clients
Akkoma is the back-end. Clients have their own repositories and often separate projects. You can check what clients work with Akkoma [on the clients page](../clients/). If you maintain a working client not listed yet, feel free to make a PR [to these docs](./#docs)!
For resources on APIs and such, check the sidebar of this page.
## Docs
The docs are written in Markdown, including certain extensions, and can be found [in the docs folder of the Akkoma repo](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/docs/). The content itself is stored in the `docs` subdirectory.
## Technology
Akkoma is written in [Elixir](https://elixir-lang.org/) and uses [Postgresql](https://www.postgresql.org/) for database. We use [Git](https://git-scm.com/) for collaboration and tracking code changes. Furthermore it can typically run on [Unix and Unix-like OS'es](https://en.wikipedia.org/wiki/Unix-like). For development, you should use an OS which [can run Akkoma](../installation/debian_based_en/).
It's good to have at least some basic understanding of at least Git and Elixir. If this is completely new for you, there's some [videos explaining Git](https://git-scm.com/doc) and Codeberg has a nice article explaining the typical [pull requests Git flow](https://docs.codeberg.org/collaborating/pull-requests-and-git-flow/). For Elixir, you can follow Elixir's own [Getting Started guide](https://elixir-lang.org/getting-started/introduction.html).
## Setting up a development environment
The best way to start is getting the software to run from source so you can start poking on it. Check out the [guides for setting up an Akkoma instance for development](setting_up_akkoma_dev/#setting-up-a-akkoma-development-environment).
## General overview
### Modules
Akkoma has several modules. There are modules for [uploading](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/uploaders), [upload filters](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/upload/filter), [translators](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/akkoma/translators)... The most famous ones are without a doubt the [MRF policies](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/web/activity_pub/mrf). Modules are often self contained and a good way to start with development because you don't have to think about much more than just the module itself. We even have an example on [writing your own MRF policy](/configuration/mrf/#writing-your-own-mrf-policy)!
Another easy entry point is the [mix tasks](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/mix/tasks/pleroma). They too are often self contained and don't need you to go through much of the code.
### Activity Streams/Activity Pub
Akkoma uses Activity Streams for both federation, as well as internal representation. It may be interesting to at least go over the specifications of [Activity Pub](https://www.w3.org/TR/activitypub/), [Activity Streams 2.0](https://www.w3.org/TR/activitystreams-core/), and [Activity Streams Vocabulary](https://www.w3.org/TR/activitystreams-vocabulary/). Note that these are not enough to have a full grasp of how everything works, but should at least give you the basics to understand how messages are passed between and inside Akkoma instances.
## Don't forget
When you make changes, you're expected to create [a Pull Request](https://akkoma.dev/AkkomaGang/akkoma/pulls). You don't have to wait until you finish to create the PR, but please do prefix the title of the PR with "WIP: " for as long as you're still working on it. The sooner you create your PR, the sooner people know what you are working on and the sooner you can get feedback and, if needed, help. You can then simply keep working on it until you are finished.
When doing changes, don't forget to add it to the relevant parts of the [CHANGELOG.md](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/CHANGELOG.md).
You're expected to write [tests](https://elixirschool.com/en/lessons/testing/basics). While code is generally stored in the `lib` directory, tests are stored in the `test` directory using a similar folder structure. Feel free to peak at other tests to see how they are done. Obviously tests are expected to pass and properly test the functionality you added. If you feel really confident, you could even try to [write a test first and then write the code needed to make it pass](https://en.wikipedia.org/wiki/Test-driven_development)!
Code is formatted using the default formatter that comes with Elixir. You can format a file with e.g. `mix format /path/to/file.ex`. To check if everything is properly formatted, you can run `mix format --check-formatted`.

If you develop on a separate branch, it's possible you did migrations that aren't merged into another branch you're working on. If you have multiple things you're working on, it's probably best to set up multiple Akkoma instances each with their own database. If you finished with a branch and want to switch back to develop to start a new branch from there, you can drop the database and recreate the database (e.g. by using `config/setup_db.psql`). The commands to drop and recreate the database can be found in [the docs](../administration/backup.md).

If you are using any additional subdomains, such as for a media proxy, you can re-run the same command with the subdomain in question. When it comes time to renew later, you will not need to run multiple times for each domain, one renew will handle it.

## Migrating back to Pleroma
Akkoma is a hard fork of Pleroma. As such, migrating back is not guaranteed to always work. But if you want to migrate back to Pleroma, you can always try. Just note that you may run into unexpected issues and you're basically on your own. The following are some tips that may help, but note that these are barely tested, so proceed at your own risk.
First you will need to roll back the database migrations. The latest migration both Akkoma and Pleroma still have in common should be 20210416051708, so roll back to that. If you run from source, that should be
Then switch back to Pleroma for updates (similar to how was done to migrate to Akkoma), and remove the front-ends. The front-ends are installed in the `frontends` folder in the [static directory](../configuration/static_dir.md). Once you are back to Pleroma, you will need to run the database migrations again. See the Pleroma documentation for this.
After this use your previous backups to restore data from diverging features.
