Oneric 0ec62acb9d Always insert Dedupe upload filter 
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.

akkoma

a smallish microblogging platform, aka the cooler pleroma

English OK 日本語OK

About

This is a fork of Pleroma, which is a microblogging server software that can federate (= exchange messages with) other servers that support ActivityPub. What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Akkoma will federate with all servers that implement ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.

Akkoma is written in Elixir and uses PostgreSQL for data storage.

For clients it supports the Mastodon client API with Pleroma extensions (see the API section on https://docs.akkoma.dev/stable/).

Differences with Pleroma

Akkoma is a faster-paced fork, it has a varied and potentially experimental feature set tailored specifically to the corner of the fediverse inhabited by the project creator and contributors.

This should not be considered a one-for-one match with pleroma; it is more opinionated in many ways, and has a smaller community (which is good or bad depending on your view)

For example, Akkoma has:

  • Custom Emoji reactions (compatible with misskey)
  • Misskey-flavoured markdown support
  • Elasticsearch and Meilisearch support for search
  • Mastodon frontend (Glitch-Soc and Fedibird flavours) support
  • Automatic post translation via DeepL or LibreTranslate
  • A multitude of heavy modifications to the Pleroma Frontend (Pleroma-FE)
  • The "bubble" concept, in which instance administrators can choose closely-related instances to make a "community of communities", so to say

And takes a more opinionated stance on issues like Domain blocks, which are enforced far more on Akkoma.

Take a look at the Changelog if you want a full list of recent changes, everything since 3.0 has been Akkoma.

Installation

OTP releases (Recommended)

If you are running Linux (glibc or musl) on x86, the recommended way to install Akkoma is by using OTP releases. OTP releases are as close as you can get to binary releases with Erlang/Elixir. The release is self-contained, and provides everything needed to boot it. The installation instructions are available here.

From Source

If your platform is not supported, or you just want to be able to edit the source code easily, you may install Akkoma from source.

Docker

Docker installation is supported via this setup

Packages

Akkoma is packaged for YunoHost and can be found and installed from the YunoHost app catalogue.

Compilation Troubleshooting

If you ever encounter compilation issues during the updating of Akkoma, you can try these commands and see if they fix things:

  • mix deps.clean --all
  • mix local.rebar
  • mix local.hex
  • rm -r _build
