Mastoduck

If it looks like a mastodon, swims like a mastodon and toots like a mastodon, then it probably is a mastodon.

Mastoduck is a reimplementation of Mastodon's streaming server in vibe.d. This module is a part of Nuage, a soft fork of Mastodon.

Installation

A working D compiler is required to compile the project. DMD is assumed to be installed in this section. If you are building using other compilers, expect to tweak a handful of settings.

First, you need to add the ddb submodule as a local dependency. Note this may interfere with other projects that depend on the official version of ddb. In case any other D project went wrong, try removing this local dependency first.

dub add-local ddb

Then compile with the appropriate flags. If something does not work, run the debug build to view detailed logs.

dub build -b debug # build the debug version
dub -b unittest # run the unit tests
DFLAGS=-check=bounds=on dub build -b release # build the release version, with bounds checking enabled to mitigate safety issues

Mastoduck does not support PostgreSQL's Unix domain sockets and SCRAM-SHA1 authentication method. You may need to enable MD5 authentication, reset the database users and change DB_HOST to 127.0.0.1 before running Mastoduck.

The compiled executable can be run from anywhere as long as the appropriate .env or .env.production file is present. It reads the RAILS_ENV environment variable and configures correspondingly. Ideally, this should work given you followed the official guide when installing Mastodon.

# Be sure to stop the Node.js streaming server first!
cd /home/mastodon/live
RAILS_ENV=development mastoduck/mastoduck

To run it in an production environment, simply set RAILS_ENV to production. Alternatively, you can manually specify the environment variables:

env RAILS_ENV=development PORT=4000 BIND=0.0.0.0 DB_HOST=127.0.0.1 DB_PORT=5432 DB_USER=mastodon DB_PASS=123456 ./mastoduck
