Continuwuity

A community-driven Matrix homeserver in Rust

Why does this exist?

The original conduwuit project has been archived and is no longer maintained. Rather than letting this Rust-based Matrix homeserver disappear, a group of community contributors have forked the project to continue its development, fix outstanding issues, and add new features.

We aim to provide a stable, well-maintained alternative for current conduwuit users and welcome newcomers seeking a lightweight, efficient Matrix homeserver.

Who are we?

We are a group of Matrix enthusiasts, developers and system administrators who have used conduwuit and believe in its potential. Our team includes both previous contributors to the original project and new developers who want to help maintain and improve this important piece of Matrix infrastructure.

We operate as an open community project, welcoming contributions from anyone interested in improving continuwuity.

What is Matrix?

Matrix is an open, federated, and extensible network for decentralized communication. Users from any Matrix homeserver can chat with users from all other homeservers over federation. Matrix is designed to be extensible and built on top of. You can even use bridges such as Matrix Appservices to communicate with users outside of Matrix, like a community on Discord.

What are the project's goals?

Continuwuity aims to:

• Maintain a stable, reliable Matrix homeserver implementation in Rust
• Improve compatibility and specification compliance with the Matrix protocol
• Fix bugs and performance issues from the original conduwuit
• Add missing features needed by homeserver administrators
• Provide comprehensive documentation and easy deployment options
• Create a sustainable development model for long-term maintenance
• Keep a lightweight, efficient codebase that can run on modest hardware

Can I try it out?

Check out the documentation for installation instructions.

There are currently no open registration Continuwuity instances available.

What are we working on?

We're working our way through all of the issues in the Forgejo project.

• Packaging & availability in more places
• Appservices bugs & features
• Improving compatibility and spec compliance
• Automated testing
• Admin API
• Policy-list controlled moderation

Can I migrate my data from x?

• Conduwuit: Yes
• Conduit: No, database is now incompatible
• Grapevine: No, database is now incompatible
• Dendrite: No
• Synapse: No

We haven't written up a guide on migrating from incompatible homeservers yet. Reach out to us if you need to do this!

How can I deploy my own?

• Deployment options

If you want to connect an appservice to Continuwuity, take a look at the appservices documentation.

Configuration

This chapter describes various ways to configure Continuwuity.

Basics

Continuwuity uses a config file for the majority of the settings, but also supports setting individual config options via commandline.

Please refer to the example config file for all of those settings.

The config file to use can be specified on the commandline when running Continuwuity by specifying the -c, --config flag. Alternatively, you can use the environment variable CONDUWUIT_CONFIG to specify the config file to used. Conduit's environment variables are supported for backwards compatibility.

Option commandline flag

Continuwuity supports setting individual config options in TOML format from the -O / --option flag. For example, you can set your server name via -O server_name=\"example.com\".

Note that the config is parsed as TOML, and shells like bash will remove quotes. So unfortunately it is required to escape quotes if the config option takes a string. This does not apply to options that take booleans or numbers:

• --option allow_registration=true works ✅
• -O max_request_size=99999999 works ✅
• -O server_name=example.com does not work ❌
• --option log=\"debug\" works ✅
• --option server_name='"example.com'" works ✅

Execute commandline flag

Continuwuity supports running admin commands on startup using the commandline argument --execute. The most notable use for this is to create an admin user on first startup.

The syntax of this is a standard admin command without the prefix such as ./conduwuit --execute "users create_user june"

An example output of a success is:

INFO conduwuit_service::admin::startup: Startup command #0 completed:
Created user with user_id: @june:girlboss.ceo and password: `<redacted>`

This commandline argument can be paired with the --option flag.

Environment variables

All of the settings that are found in the config file can be specified by using environment variables. The environment variable names should be all caps and prefixed with CONDUWUIT_.

For example, if the setting you are changing is max_request_size, then the environment variable to set is CONDUWUIT_MAX_REQUEST_SIZE.

To modify config options not in the [global] context such as [global.well_known], use the __ suffix split: CONDUWUIT_WELL_KNOWN__SERVER

Conduit's environment variables are supported for backwards compatibility (e.g. CONDUIT_SERVER_NAME).

#
# If you are using Docker or a container NAT networking setup, this must

#
# For reverse proxying, see:

#
#port = 8008

# The UNIX socket continuwuity will listen on.
#
# continuwuity cannot listen on both an IP address and a UNIX socket. If
# listening on a UNIX socket, you MUST remove/comment the `address` key.
#
# Remember to make sure that your reverse proxy has access to this socket
# file, either by adding your reverse proxy to the appropriate user group

# Enable database pool affinity support. On supporting systems, block

#
#db_pool_affinity = true

# Sets the number of worker threads in the frontend-pool of the database.

# When db_pool_affinity is enabled and detected, the size of any worker
# group will not exceed the determined value. This is necessary when

# degrade performance.
#
# The value is multiplied by the number of cores which share a device

#
#db_pool_workers_limit = 64

# Determines the size of the queues feeding the database's frontend-pool.
# The size of the queue is determined by multiplying this value with the
# number of pool workers. When this queue is full, tokio tasks conducting
# requests will yield until space is available; this is good for
# flow-control by avoiding buffer-bloat, but can inhibit throughput if
# too low.
#
#db_pool_queue_mult = 4

# Sets the initial value for the concurrency of streams. This value simply
# allows overriding the default in the code. The default is 32, which is
# the same as the default in the code. Note this value is itself
# overridden by the computed stream_width_scale, unless that is disabled;
# this value can serve as a fixed-width instead.
#
#stream_width_default = 32

# Scales the stream width starting from a base value detected for the
# specific system. The base value is the database pool worker count
# determined from the hardware queue size (e.g. 32 for SSD or 64 or 128+
# for NVMe). This float allows scaling the width up or down by multiplying
# it (e.g. 1.5, 2.0, etc). The maximum result can be the size of the pool
# queue (see: db_pool_queue_mult) as any larger value will stall the tokio
# task. The value can also be scaled down (e.g. 0.5)  to improve
# responsiveness for many users at the cost of throughput for each.
#
# Setting this value to 0.0 causes the stream width to be fixed at the
# value of stream_width_default. The default scale is 1.0 to match the
# capabilities detected for the system.
#
#stream_width_scale = 1.0

# Sets the initial amplification factor. This controls batch sizes of
# requests made by each pool worker, multiplying the throughput of each
# stream. This value is somewhat abstract from specific hardware
# characteristics and can be significantly larger than any thread count or
# queue size. This is because each database query may require several
# index lookups, thus many database queries in a batch may make progress
# independently while also sharing index and data blocks which may or may
# not be cached. It is worthwhile to submit huge batches to reduce
# complexity. The maximum value is 32768, though sufficient hardware is
# still advised for that.
#
#stream_amplification = 1024

# Number of sender task workers; determines sender parallelism. Default is

Deploying

This chapter describes various ways to deploy Continuwuity.

Generic deployment documentation

Getting help

If you run into any problems while setting up Continuwuity, ask us in #continuwuity:continuwuity.org or open an issue on Forgejo.

Installing Continuwuity

Static prebuilt binary

You may simply download the binary that fits your machine architecture (x86_64 or aarch64). Run uname -m to see what you need.

Prebuilt fully static musl binaries can be downloaded from the latest tagged release here or main CI branch workflow artifact output. These also include Debian/Ubuntu packages.

These can be curl'd directly from. ci-bins are CI workflow binaries by commit hash/revision, and releases are tagged releases. Sort by descending last modified for the latest.

These binaries have jemalloc and io_uring statically linked and included with them, so no additional dynamic dependencies need to be installed.

For the best performance; if using an x86_64 CPU made in the last ~15 years, we recommend using the -haswell- optimised binaries. This sets -march=haswell which is the most compatible and highest performance with optimised binaries. The database backend, RocksDB, most benefits from this as it will then use hardware accelerated CRC32 hashing/checksumming which is critical for performance.

Compiling

Alternatively, you may compile the binary yourself. We recommend using Nix (or Lix) to build Continuwuity as this has the most guaranteed reproducibiltiy and easiest to get a build environment and output going. This also allows easy cross-compilation.

You can run the nix build -L .#static-x86_64-linux-musl-all-features or nix build -L .#static-aarch64-linux-musl-all-features commands based on architecture to cross-compile the necessary static binary located at result/bin/conduwuit. This is reproducible with the static binaries produced in our CI.

If wanting to build using standard Rust toolchains, make sure you install:

• liburing-dev on the compiling machine, and liburing on the target host
• LLVM and libclang for RocksDB

You can build Continuwuity using cargo build --release --all-features

Adding a Continuwuity user

While Continuwuity can run as any user it is better to use dedicated users for different services. This also allows you to make sure that the file permissions are correctly set up.

In Debian, you can use this command to create a Continuwuity user:

sudo adduser --system continuwuity --group --disabled-login --no-create-home

For distros without adduser (or where it's a symlink to useradd):

sudo useradd -r --shell /usr/bin/nologin --no-create-home continuwuity

Forwarding ports in the firewall or the router

Matrix's default federation port is port 8448, and clients must be using port 443. If you would like to use only port 443, or a different port, you will need to setup delegation. Continuwuity has config options for doing delegation, or you can configure your reverse proxy to manually serve the necessary JSON files to do delegation (see the [global.well_known] config section).

If Continuwuity runs behind a router or in a container and has a different public IP address than the host system these public ports need to be forwarded directly or indirectly to the port mentioned in the config.

Note for NAT users; if you have trouble connecting to your server from the inside of your network, you need to research your router and see if it supports "NAT hairpinning" or "NAT loopback".

If your router does not support this feature, you need to research doing local DNS overrides and force your Matrix DNS records to use your local IP internally. This can be done at the host level using /etc/hosts. If you need this to be on the network level, consider something like NextDNS or Pi-Hole.

Setting up a systemd service

Two example systemd units for Continuwuity can be found on the configuration page. You may need to change the ExecStart= path to where you placed the Continuwuity binary if it is not /usr/bin/conduwuit.

On systems where rsyslog is used alongside journald (i.e. Red Hat-based distros and OpenSUSE), put $EscapeControlCharactersOnReceive off inside /etc/rsyslog.conf to allow color in logs.

If you are using a different database_path other than the systemd unit configured default /var/lib/conduwuit, you need to add your path to the systemd unit's ReadWritePaths=. This can be done by either directly editing conduwuit.service and reloading systemd, or running systemctl edit conduwuit.service and entering the following:

[Service]
ReadWritePaths=/path/to/custom/database/path

Creating the Continuwuity configuration file

Now we need to create the Continuwuity's config file in /etc/continuwuity/continuwuity.toml. The example config can be found at conduwuit-example.toml.

Please take a moment to read the config. You need to change at least the server name.

RocksDB is the only supported database backend.

Setting the correct file permissions

If you are using a dedicated user for Continuwuity, you will need to allow it to read the config. To do that you can run this:

sudo chown -R root:root /etc/conduwuit
sudo chmod -R 755 /etc/conduwuit

If you use the default database path you also need to run this:

sudo mkdir -p /var/lib/conduwuit/
sudo chown -R continuwuity:continuwuity /var/lib/conduwuit/
sudo chmod 700 /var/lib/conduwuit/

Setting up the Reverse Proxy

We recommend Caddy as a reverse proxy, as it is trivial to use, handling TLS certificates, reverse proxy headers, etc transparently with proper defaults. For other software, please refer to their respective documentation or online guides.

Caddy

After installing Caddy via your preferred method, create /etc/caddy/conf.d/conduwuit_caddyfile and enter this (substitute for your server name).

your.server.name, your.server.name:8448 {
    # TCP reverse_proxy
    reverse_proxy 127.0.0.1:6167
    # UNIX socket
    #reverse_proxy unix//run/conduwuit/conduwuit.sock
}

That's it! Just start and enable the service and you're set.

sudo systemctl enable --now caddy

Other Reverse Proxies

As we would prefer our users to use Caddy, we will not provide configuration files for other proxys.

You will need to reverse proxy everything under following routes:

• /_matrix/ - core Matrix C-S and S-S APIs
• /_conduwuit/ - ad-hoc Continuwuity routes such as /local_user_count and /server_version

You can optionally reverse proxy the following individual routes:

• /.well-known/matrix/client and /.well-known/matrix/server if using Continuwuity to perform delegation (see the [global.well_known] config section)
• /.well-known/matrix/support if using Continuwuity to send the homeserver admin contact and support page (formerly known as MSC1929)
• / if you would like to see hewwo from conduwuit woof! at the root

See the following spec pages for more details on these files:

• /.well-known/matrix/server
• /.well-known/matrix/client
• /.well-known/matrix/support

Examples of delegation:

• https://puppygock.gay/.well-known/matrix/server
• https://puppygock.gay/.well-known/matrix/client

For Apache and Nginx there are many examples available online.

Lighttpd is not supported as it seems to mess with the X-Matrix Authorization header, making federation non-functional. If a workaround is found, feel free to share to get it added to the documentation here.

If using Apache, you need to use nocanon in your ProxyPass directive to prevent httpd from messing with the X-Matrix header (note that Apache isn't very good as a general reverse proxy and we discourage the usage of it if you can).

If using Nginx, you need to give Continuwuity the request URI using $request_uri, or like so:

• proxy_pass http://127.0.0.1:6167$request_uri;
• proxy_pass http://127.0.0.1:6167;

Nginx users need to increase client_max_body_size (default is 1M) to match max_request_size defined in conduwuit.toml.

You're done

Now you can start Continuwuity with:

sudo systemctl start conduwuit

Set it to start automatically when your system boots with:

sudo systemctl enable conduwuit

How do I know it works?

You can open a Matrix client, enter your homeserver and try to register.

You can also use these commands as a quick health check (replace your.server.name).

curl https://your.server.name/_conduwuit/server_version

# If using port 8448
curl https://your.server.name:8448/_conduwuit/server_version

# If federation is enabled
curl https://your.server.name:8448/_matrix/federation/v1/version

• To check if your server can talk with other homeservers, you can use the Matrix Federation Tester. If you can register but cannot join federated rooms check your config again and also check if the port 8448 is open and forwarded correctly.

What's next?

Audio/Video calls

For Audio/Video call functionality see the TURN Guide.

Appservices

If you want to set up an appservice, take a look at the Appservice Guide.

Continuwuity for NixOS

Continuwuity can be acquired by Nix (or Lix) from various places:

• The flake.nix at the root of the repo
• The default.nix at the root of the repo
• From Continuwuity's binary cache

NixOS module

The flake.nix and default.nix do not currently provide a NixOS module (contributions welcome!), so services.matrix-conduit from Nixpkgs can be used to configure Continuwuity.

Conduit NixOS Config Module and SQLite

Beware! The services.matrix-conduit module defaults to SQLite as a database backend. Continuwuity dropped SQLite support in favor of exclusively supporting the much faster RocksDB. Make sure that you are using the RocksDB backend before migrating!

There is a tool to migrate a Conduit SQLite database to RocksDB.

If you want to run the latest code, you should get Continuwuity from the flake.nix or default.nix and set services.matrix-conduit.package appropriately to use Continuwuity instead of Conduit.

UNIX sockets

Due to the lack of a Continuwuity NixOS module, when using the services.matrix-conduit module a workaround like the one below is necessary to use UNIX sockets. This is because the UNIX socket option does not exist in Conduit, and the module forcibly sets the address and port config options.

options.services.matrix-conduit.settings = lib.mkOption {
  apply = old: old // (
    if (old.global ? "unix_socket_path")
    then { global = builtins.removeAttrs old.global [ "address" "port" ]; }
    else {  }
  );
};

Additionally, the matrix-conduit systemd unit in the module does not allow the AF_UNIX socket address family in their systemd unit's RestrictAddressFamilies= which disallows the namespace from accessing or creating UNIX sockets and has to be enabled like so:

systemd.services.conduit.serviceConfig.RestrictAddressFamilies = [ "AF_UNIX" ];

Even though those workarounds are feasible a Continuwuity NixOS configuration module, developed and published by the community, would be appreciated.

jemalloc and hardened profile

Continuwuity uses jemalloc by default. This may interfere with the hardened.nix profile due to them using scudo by default. You must either disable/hide scudo from Continuwuity, or disable jemalloc like so:

let
    conduwuit = pkgs.unstable.conduwuit.override {
      enableJemalloc = false;
    };
in

Continuwuity for Docker

Docker

To run Continuwuity with Docker you can either build the image yourself or pull it from a registry.

Use a registry

OCI images for Continuwuity are available in the registries listed below.

Use

docker image pull $LINK

to pull it to your machine.

Run

When you have the image you can simply run it with

docker run -d -p 8448:6167 \
    -v db:/var/lib/continuwuity/ \
    -e CONTINUWUITY_SERVER_NAME="your.server.name" \
    -e CONTINUWUITY_ALLOW_REGISTRATION=false \
    --name continuwuity $LINK

or you can use docker compose.

The -d flag lets the container run in detached mode. You may supply an optional continuwuity.toml config file, the example config can be found here. You can pass in different env vars to change config values on the fly. You can even configure Continuwuity completely by using env vars. For an overview of possible values, please take a look at the docker-compose.yml file.

If you just want to test Continuwuity for a short time, you can use the --rm flag, which will clean up everything related to your container after you stop it.

Docker-compose

If the docker run command is not for you or your setup, you can also use one of the provided docker-compose files.

Depending on your proxy setup, you can use one of the following files;

• If you already have a traefik instance set up, use docker-compose.for-traefik.yml
• If you don't have a traefik instance set up and would like to use it, use docker-compose.with-traefik.yml
• If you want a setup that works out of the box with caddy-docker-proxy, use docker-compose.with-caddy.yml and replace all example.com placeholders with your own domain
• For any other reverse proxy, use docker-compose.yml

When picking the traefik-related compose file, rename it so it matches docker-compose.yml, and rename the override file to docker-compose.override.yml. Edit the latter with the values you want for your server.

When picking the caddy-docker-proxy compose file, it's important to first create the caddy network before spinning up the containers:

docker network create caddy

After that, you can rename it so it matches docker-compose.yml and spin up the containers!

Additional info about deploying Continuwuity can be found here.

Build

Official Continuwuity images are built using Docker Buildx and the Dockerfile found at docker/Dockerfile. This approach uses common Docker tooling and enables multi-platform builds efficiently.

The resulting images are broadly compatible with Docker and other container runtimes like Podman or containerd.

The images do not contain a shell. They contain only the Continuwuity binary, required libraries, TLS certificates and metadata. Please refer to the docker/Dockerfile for the specific details of the image composition.

To build an image locally using Docker Buildx, you can typically run a command like:

# Build for the current platform and load into the local Docker daemon
docker buildx build --load --tag continuwuity:latest -f docker/Dockerfile .

# Example: Build for specific platforms and push to a registry.
# docker buildx build --platform linux/amd64,linux/arm64 --tag registry.io/org/continuwuity:latest -f docker/Dockerfile . --push

# Example: Build binary optimized for the current CPU
# docker buildx build --load --tag continuwuity:latest --build-arg TARGET_CPU=native -f docker/Dockerfile .

Refer to the Docker Buildx documentation for more advanced build options.

Run

If you already have built the image or want to use one from the registries, you can just start the container and everything else in the compose file in detached mode with:

docker compose up -d

Note: Don't forget to modify and adjust the compose file to your needs.

Use Traefik as Proxy

As a container user, you probably know about Traefik. It is a easy to use reverse proxy for making containerized app and services available through the web. With the two provided files, docker-compose.for-traefik.yml (or docker-compose.with-traefik.yml) and docker-compose.override.yml, it is equally easy to deploy and use Continuwuity, with a little caveat. If you already took a look at the files, then you should have seen the well-known service, and that is the little caveat. Traefik is simply a proxy and loadbalancer and is not able to serve any kind of content, but for Continuwuity to federate, we need to either expose ports 443 and 8448 or serve two endpoints .well-known/matrix/client and .well-known/matrix/server.

With the service well-known we use a single nginx container that will serve those two files.

Voice communication

See the TURN page.

Continuwuity for Kubernetes

Continuwuity doesn't support horizontal scalability or distributed loading natively, however a community maintained Helm Chart is available here to run conduwuit on Kubernetes: https://gitlab.cronce.io/charts/conduwuit

This should be compatible with continuwuity, but you will need to change the image reference.

Should changes need to be made, please reach out to the maintainer as this is not maintained/controlled by the Continuwuity maintainers.

Continuwuity for Arch Linux

Continuwuity is available on the archlinuxcn repository and AUR, with the same package name continuwuity, which includes latest taggged version. The development version is available on AUR as continuwuity-git

Simply install the continuwuity package. Configure the service in /etc/conduwuit/conduwuit.toml, then enable/start the continuwuity.service.

Continuwuity for Debian

Information about downloading and deploying the Debian package. This may also be referenced for other apt-based distros such as Ubuntu.

Installation

It is recommended to see the generic deployment guide for further information if needed as usage of the Debian package is generally related.

No apt repository is currently offered yet, it is in the works/development.

Configuration

When installed, the example config is placed at /etc/conduwuit/conduwuit.toml as the default config. The config mentions things required to be changed before starting.

You can tweak more detailed settings by uncommenting and setting the config options in /etc/conduwuit/conduwuit.toml.

Running

The package uses the conduwuit.service systemd unit file to start and stop Continuwuity. The binary is installed at /usr/sbin/conduwuit.

This package assumes by default that conduwuit will be placed behind a reverse proxy. The default config options apply (listening on localhost and TCP port 6167). Matrix federation requires a valid domain name and TLS, so you will need to set up TLS certificates and renewal for it to work properly if you intend to federate.

Consult various online documentation and guides on setting up a reverse proxy and TLS. Caddy is documented at the generic deployment guide as it's the easiest and most user friendly.

Continuwuity for FreeBSD

Continuwuity at the moment does not provide FreeBSD builds or have FreeBSD packaging, however Continuwuity does build and work on FreeBSD using the system-provided RocksDB.

Contributions for getting Continuwuity packaged are welcome.

Setting up TURN/STURN

In order to make or receive calls, a TURN server is required. Continuwuity suggests using Coturn for this purpose, which is also available as a Docker image.

Configuration

Create a configuration file called coturn.conf containing:

use-auth-secret
static-auth-secret=<a secret key>
realm=<your server domain>

A common way to generate a suitable alphanumeric secret key is by using pwgen -s 64 1.

These same values need to be set in Continuwuity. See the example config in the TURN section for configuring these and restart Continuwuity after.

turn_secret or a path to turn_secret_file must have a value of your coturn static-auth-secret, or use turn_username and turn_password if using legacy username:password TURN authentication (not preferred).

turn_uris must be the list of TURN URIs you would like to send to the client. Typically you will just replace the example domain example.turn.uri with the realm you set from the example config.

If you are using TURN over TLS, you can replace turn: with turns: in the turn_uris config option to instruct clients to attempt to connect to TURN over TLS. This is highly recommended.

If you need unauthenticated access to the TURN URIs, or some clients may be having trouble, you can enable turn_guest_access in Continuwuity which disables authentication for the TURN URI endpoint /_matrix/client/v3/voip/turnServer

Run

Run the Coturn image using

docker run -d --network=host -v
$(pwd)/coturn.conf:/etc/coturn/turnserver.conf coturn/coturn

or docker-compose. For the latter, paste the following section into a file called docker-compose.yml and run docker compose up -d in the same directory.

version: 3
services:
    turn:
      container_name: coturn-server
      image: docker.io/coturn/coturn
      restart: unless-stopped
      network_mode: "host"
      volumes:
        - ./coturn.conf:/etc/coturn/turnserver.conf

To understand why the host networking mode is used and explore alternative configuration options, please visit Coturn's Docker documentation.

For security recommendations see Synapse's Coturn documentation.

Setting up Appservices

Getting help

If you run into any problems while setting up an Appservice: ask us in #continuwuity:continuwuity.org or open an issue on Forgejo.

Set up the appservice - general instructions

Follow whatever instructions are given by the appservice. This usually includes downloading, changing its config (setting domain, homeserver url, port etc.) and later starting it.

At some point the appservice guide should ask you to add a registration yaml file to the homeserver. In Synapse you would do this by adding the path to the homeserver.yaml, but in Continuwuity you can do this from within Matrix:

First, go into the #admins room of your homeserver. The first person that registered on the homeserver automatically joins it. Then send a message into the room like this:

!admin appservices register
```
paste
the
contents
of
the
yaml
registration
here
```

You can confirm it worked by sending a message like this: !admin appservices list

The server bot should answer with Appservices (1): your-bridge

Then you are done. Continuwuity will send messages to the appservices and the appservice can send requests to the homeserver. You don't need to restart Continuwuity, but if it doesn't work, restarting while the appservice is running could help.

Appservice-specific instructions

Remove an appservice

To remove an appservice go to your admin room and execute

!admin appservices unregister <name>

where <name> one of the output of appservices list.

Maintaining your Continuwuity setup

Moderation

Continuwuity has moderation through admin room commands. "binary commands" (medium priority) and an admin API (low priority) is planned. Some moderation-related config options are available in the example config such as "global ACLs" and blocking media requests to certain servers. See the example config for the moderation config options under the "Moderation / Privacy / Security" section.

Continuwuity has moderation admin commands for:

• managing room aliases (!admin rooms alias)
• managing room directory (!admin rooms directory)
• managing room banning/blocking and user removal (!admin rooms moderation)
• managing user accounts (!admin users)
• fetching /.well-known/matrix/support from servers (!admin federation)
• blocking incoming federation for certain rooms (not the same as room banning) (!admin federation)
• deleting media (see the media section)

Any commands with -list in them will require a codeblock in the message with each object being newline delimited. An example of doing this is:

!admin rooms moderation ban-list-of-rooms
```
!roomid1:server.name
#badroomalias1:server.name
!roomid2:server.name
!roomid3:server.name
#badroomalias2:server.name
```

Database (RocksDB)

Generally there is very little you need to do. Compaction is ran automatically based on various defined thresholds tuned for Continuwuity to be high performance with the least I/O amplifcation or overhead. Manually running compaction is not recommended, or compaction via a timer, due to creating unnecessary I/O amplification. RocksDB is built with io_uring support via liburing for improved read performance.

RocksDB troubleshooting can be found in the RocksDB section of troubleshooting.

Compression

Some RocksDB settings can be adjusted such as the compression method chosen. See the RocksDB section in the example config.

btrfs users have reported that database compression does not need to be disabled on Continuwuity as the filesystem already does not attempt to compress. This can be validated by using filefrag -v on a .SST file in your database, and ensure the physical_offset matches (no filesystem compression). It is very important to ensure no additional filesystem compression takes place as this can render unbuffered Direct IO inoperable, significantly slowing down read and write performance. See https://btrfs.readthedocs.io/en/latest/Compression.html#compatibility

Compression is done using the COW mechanism so it’s incompatible with nodatacow. Direct IO read works on compressed files but will fall back to buffered writes and leads to no compression even if force compression is set. Currently nodatasum and compression don’t work together.

Files in database

Do not touch any of the files in the database directory. This must be said due to users being mislead by the .log files in the RocksDB directory, thinking they're server logs or database logs, however they are critical RocksDB files related to WAL tracking.

The only safe files that can be deleted are the LOG files (all caps). These are the real RocksDB telemetry/log files, however Continuwuity has already configured to only store up to 3 RocksDB LOG files due to generally being useless for average users unless troubleshooting something low-level. If you would like to store nearly none at all, see the rocksdb_max_log_files config option.

Backups

Currently only RocksDB supports online backups. If you'd like to backup your database online without any downtime, see the !admin server command for the backup commands and the database_backup_path config options in the example config. Please note that the format of the database backup is not the exact same. This is unfortunately a bad design choice by Facebook as we are using the database backup engine API from RocksDB, however the data is still there and can still be joined together.

To restore a backup from an online RocksDB backup:

• shutdown Continuwuity
• create a new directory for merging together the data
• in the online backup created, copy all .sst files in $DATABASE_BACKUP_PATH/shared_checksum to your new directory
• trim all the strings so instead of ######_sxxxxxxxxx.sst, it reads ######.sst. A way of doing this with sed and bash is for file in *.sst; do mv "$file" "$(echo "$file" | sed 's/_s.*/.sst/')"; done
• copy all the files in $DATABASE_BACKUP_PATH/1 (or the latest backup number if you have multiple) to your new directory
• set your database_path config option to your new directory, or replace your old one with the new one you crafted
• start up Continuwuity again and it should open as normal

If you'd like to do an offline backup, shutdown Continuwuity and copy your database_path directory elsewhere. This can be restored with no modifications needed.

Backing up media is also just copying the media/ directory from your database directory.

Media

Media still needs various work, however Continuwuity implements media deletion via:

• MXC URI or Event ID (unencrypted and attempts to find the MXC URI in the event)
• Delete list of MXC URIs
• Delete remote media in the past N seconds/minutes via filesystem metadata on the file created time (btime) or file modified time (mtime)

See the !admin media command for further information. All media in Continuwuity is stored at $DATABASE_DIR/media. This will be configurable soon.

If you are finding yourself needing extensive granular control over media, we recommend looking into Matrix Media Repo. Continuwuity intends to implement various utilities for media, but MMR is dedicated to extensive media management.

Built-in S3 support is also planned, but for now using a "S3 filesystem" on media/ works. Continuwuity also sends a Cache-Control header of 1 year and immutable for all media requests (download and thumbnail) to reduce unnecessary media requests from browsers, reduce bandwidth usage, and reduce load.

Troubleshooting Continuwuity

Docker users ⚠️

Docker can be difficult to use and debug. It's common for Docker misconfigurations to cause issues, particularly with networking and permissions. Please check that your issues are not due to problems with your Docker setup.

Continuwuity and Matrix issues

Lost access to admin room

You can reinvite yourself to the admin room through the following methods:

• Use the --execute "users make_user_admin <username>" Continuwuity binary argument once to invite yourslf to the admin room on startup
• Use the Continuwuity console/CLI to run the users make_user_admin command
• Or specify the emergency_password config option to allow you to temporarily log into the server account (@conduit) from a web client

General potential issues

Potential DNS issues when using Docker

Docker's DNS setup for containers in a non-default network intercepts queries to enable resolving of container hostnames to IP addresses. However, due to performance issues with Docker's built-in resolver, this can cause DNS queries to take a long time to resolve, resulting in federation issues.

This is particularly common with Docker Compose, as custom networks are easily created and configured.

Symptoms of this include excessively long room joins (30+ minutes) from very long DNS timeouts, log entries of "mismatching responding nameservers", and/or partial or non-functional inbound/outbound federation.

This is not a bug in continuwuity. Docker's default DNS resolver is not suitable for heavy DNS activity, which is normal for federated protocols like Matrix.

Workarounds:

• Use DNS over TCP via the config option query_over_tcp_only = true
• Bypass Docker's default DNS setup and instead allow the container to use and communicate with your host's DNS servers. Typically, this can be done by mounting the host's /etc/resolv.conf.

DNS No connections available error message

If you receive spurious amounts of error logs saying "DNS No connections available", this is due to your DNS server (servers from /etc/resolv.conf) being overloaded and unable to handle typical Matrix federation volume. Some users have reported that the upstream servers are rate-limiting them as well when they get this error (e.g. popular upstreams like Google DNS).

Matrix federation is extremely heavy and sends wild amounts of DNS requests. Unfortunately this is by design and has only gotten worse with more server/destination resolution steps. Synapse also expects a very perfect DNS setup.

There are some ways you can reduce the amount of DNS queries, but ultimately the best solution/fix is selfhosting a high quality caching DNS server like Unbound without any upstream resolvers, and without DNSSEC validation enabled.

DNSSEC validation is highly recommended to be disabled due to DNSSEC being very computationally expensive, and is extremely susceptible to denial of service, especially on Matrix. Many servers also strangely have broken DNSSEC setups and will result in non-functional federation.

Continuwuity cannot provide a "works-for-everyone" Unbound DNS setup guide, but the official Unbound tuning guide and the Unbound Arch Linux wiki page may be of interest. Disabling DNSSEC on Unbound is commenting out trust-anchors config options and removing the validator module.

Avoid using systemd-resolved as it does not perform very well under high load, and we have identified its DNS caching to not be very effective.

dnsmasq can possibly work, but it does not support TCP fallback which can be problematic when receiving large DNS responses such as from large SRV records. If you still want to use dnsmasq, make sure you disable dns_tcp_fallback in Continuwuity config.

Raising dns_cache_entries in Continuwuity config from the default can also assist in DNS caching, but a full-fledged external caching resolver is better and more reliable.

If you don't have IPv6 connectivity, changing ip_lookup_strategy to match your setup can help reduce unnecessary AAAA queries (1 - Ipv4Only (Only query for A records, no AAAA/IPv6)).

If your DNS server supports it, some users have reported enabling query_over_tcp_only to force only TCP querying by default has improved DNS reliability at a slight performance cost due to TCP overhead.

RocksDB / database issues

Database corruption

If your database is corrupted and is failing to start (e.g. checksum mismatch), it may be recoverable but careful steps must be taken, and there is no guarantee it may be recoverable.

The first thing that can be done is launching Continuwuity with the rocksdb_repair config option set to true. This will tell RocksDB to attempt to repair itself at launch. If this does not work, disable the option and continue reading.

RocksDB has the following recovery modes:

• TolerateCorruptedTailRecords
• AbsoluteConsistency
• PointInTime
• SkipAnyCorruptedRecord

By default, Continuwuity uses TolerateCorruptedTailRecords as generally these may be due to bad federation and we can re-fetch the correct data over federation. The RocksDB default is PointInTime which will attempt to restore a "snapshot" of the data when it was last known to be good. This data can be either a few seconds old, or multiple minutes prior. PointInTime may not be suitable for default usage due to clients and servers possibly not being able to handle sudden "backwards time travels", and AbsoluteConsistency may be too strict.

AbsoluteConsistency will fail to start the database if any sign of corruption is detected. SkipAnyCorruptedRecord will skip all forms of corruption unless it forbids the database from opening (e.g. too severe). Usage of SkipAnyCorruptedRecord voids any support as this may cause more damage and/or leave your database in a permanently inconsistent state, but it may do something if PointInTime does not work as a last ditch effort.

With this in mind:

• First start Continuwuity with the PointInTime recovery method. See the example config for how to do this using rocksdb_recovery_mode
• If your database successfully opens, clients are recommended to clear their client cache to account for the rollback
• Leave your Continuwuity running in PointInTime for at least 30-60 minutes so as much possible corruption is restored
• If all goes will, you should be able to restore back to using TolerateCorruptedTailRecords and you have successfully recovered your database

Debugging

Note that users should not really be debugging things. If you find yourself debugging and find the issue, please let us know and/or how we can fix it. Various debug commands can be found in !admin debug.

Debug/Trace log level

Continuwuity builds without debug or trace log levels at compile time by default for substantial performance gains in CPU usage and improved compile times. If you need to access debug/trace log levels, you will need to build without the release_max_log_level feature or use our provided static debug binaries.

Changing log level dynamically

Continuwuity supports changing the tracing log environment filter on-the-fly using the admin command !admin debug change-log-level <log env filter>. This accepts a string without quotes the same format as the log config option.

Example: !admin debug change-log-level debug

This can also accept complex filters such as: !admin debug change-log-level info,conduit_service[{dest="example.com"}]=trace,ruma_state_res=trace !admin debug change-log-level info,conduit_service[{dest="example.com"}]=trace,conduit_service[send{dest="example.org"}]=trace

And to reset the log level to the one that was set at startup / last config load, simply pass the --reset flag.

!admin debug change-log-level --reset

Pinging servers

Continuwuity can ping other servers using !admin debug ping <server>. This takes a server name and goes through the server discovery process and queries /_matrix/federation/v1/version. Errors are outputted.

While it does measure the latency of the request, it is not indicative of server performance on either side as that endpoint is completely unauthenticated and simply fetches a string on a static JSON endpoint. It is very low cost both bandwidth and computationally.

Allocator memory stats

When using jemalloc with jemallocator's stats feature (--enable-stats), you can see Continuwuity's high-level allocator stats by using !admin server memory-usage at the bottom.

If you are a developer, you can also view the raw jemalloc statistics with !admin debug memory-stats. Please note that this output is extremely large which may only be visible in the Continuwuity console CLI due to PDU size limits, and is not easy for non-developers to understand.

admin debug force-set-room-state-from-server

• Forcefully replaces the room state of our local copy of the specified room, with the copy (auth chain and room state events) the specified remote server says.

A common desire for room deletion is to simply "reset" our copy of the room. While this admin command is not a replacement for that, if you know you have split/broken room state and you know another server in the room that has the best/working room state, this command can let you use their room state. Such example is your server saying users are in a room, but other servers are saying they're not in the room in question.

This command will get the latest PDU in the room we know about, and request the room state at that point in time via /_matrix/federation/v1/state/{roomId}.

Usage: admin debug force-set-room-state-from-server <ROOM_ID> <SERVER_NAME> [EVENT_ID]

Arguments:

• <ROOM_ID> — The impacted room ID

Development

Information about developing the project. If you are only interested in using it, you can safely ignore this page. If you plan on contributing, see the contributor's guide.

Continuwuity project layout

Continuwuity uses a collection of sub-crates, packages, or workspace members that indicate what each general area of code is for. All of the workspace members are under src/. The workspace definition is at the top level / root Cargo.toml.

The crate names are generally self-explanatory:

• admin is the admin room
• api is the HTTP API, Matrix C-S and S-S endpoints, etc
• core is core Continuwuity functionality like config loading, error definitions, global utilities, logging infrastructure, etc
• database is RocksDB methods, helpers, RocksDB config, and general database definitions, utilities, or functions
• macros are Continuwuity Rust macros like general helper macros, logging and error handling macros, and syn and procedural macros used for admin room commands and others
• main is the "primary" sub-crate. This is where the main() function lives, tokio worker and async initialisation, Sentry initialisation, clap init, and signal handling. If you are adding new Rust features, they must go here.
• router is the webserver and request handling bits, using axum, tower, tower-http, hyper, etc, and the global server state to access services.
• service is the high-level database definitions and functions for data, outbound/sending code, and other business logic such as media fetching.

It is highly unlikely you will ever need to add a new workspace member, but if you truly find yourself needing to, we recommend reaching out to us in the Matrix room for discussions about it beforehand.

The primary inspiration for this design was apart of hot reloadable development, to support "Continuwuity as a library" where specific parts can simply be swapped out. There is evidence Conduit wanted to go this route too as axum is technically an optional feature in Conduit, and can be compiled without the binary or axum library for handling inbound web requests; but it was never completed or worked.

See the Rust documentation on Workspaces for general questions and information on Cargo workspaces.

Adding compile-time features

If you'd like to add a compile-time feature, you must first define it in the main workspace crate located in src/main/Cargo.toml. The feature must enable a feature in the other workspace crate(s) you intend to use it in. Then the said workspace crate(s) must define the feature there in its Cargo.toml.

So, if this is adding a feature to the API such as woof, you define the feature in the api crate's Cargo.toml as woof = []. The feature definition in main's Cargo.toml will be woof = ["conduwuit-api/woof"].

The rationale for this is due to Rust / Cargo not supporting "workspace level features", we must make a choice of; either scattering features all over the workspace crates, making it difficult for anyone to add or remove default features; or define all the features in one central workspace crate that propagate down/up to the other workspace crates. It is a Cargo pitfall, and we'd like to see better developer UX in Rust's Workspaces.

Additionally, the definition of one single place makes "feature collection" in our Nix flake a million times easier instead of collecting and deduping them all from searching in all the workspace crates' Cargo.tomls. Though we wouldn't need to do this if Rust supported workspace-level features to begin with.

List of forked dependencies

During Continuwuity (and prior projects) development, we have had to fork some dependencies to support our use-cases. These forks exist for various reasons including features that upstream projects won't accept, faster-paced development, Continuwuity-specific usecases, or lack of time to upstream changes.

All forked dependencies are maintained under the continuwuation organization on Forgejo:

• ruwuma - Fork of ruma/ruma with various performance improvements, more features and better client/server interop
• rocksdb - Fork of facebook/rocksdb via @zaidoon1 with liburing build fixes and GCC debug build fixes
• jemallocator - Fork of tikv/jemallocator fixing musl builds, suspicious code, and adding support for redzones in Valgrind
• rustyline-async - Fork of zyansheep/rustyline-async with tab completion callback and CTRL+\ signal quit event for Continuwuity console CLI
• rust-rocksdb - Fork of rust-rocksdb/rust-rocksdb fixing musl build issues, removing unnecessary gtest include, and using our RocksDB and jemallocator forks
• tracing - Fork of tokio-rs/tracing implementing Clone for EnvFilter to support dynamically changing tracing environments

Debugging with tokio-console

tokio-console can be a useful tool for debugging and profiling. To make a tokio-console-enabled build of Continuwuity, enable the tokio_console feature, disable the default release_max_log_level feature, and set the --cfg tokio_unstable flag to enable experimental tokio APIs. A build might look like this:

RUSTFLAGS="--cfg tokio_unstable" cargo +nightly build \
    --release \
    --no-default-features \
    --features=systemd,element_hacks,gzip_compression,brotli_compression,zstd_compression,tokio_console

You will also need to enable the tokio_console config option in Continuwuity when starting it. This was due to tokio-console causing gradual memory leak/usage if left enabled.

Building Docker Images

To build a Docker image for Continuwuity, use the standard Docker build command:

docker build -f docker/Dockerfile .

The image can be cross-compiled for different architectures.

Contributing guide

This page is about contributing to Continuwuity. The development page may be of interest for you as well.

If you would like to work on an issue that is not assigned, preferably ask in the Matrix room first at #continuwuity:continuwuity.org, and comment on it.

Linting and Formatting

It is mandatory all your changes satisfy the lints (clippy, rustc, rustdoc, etc) and your code is formatted via the nightly rustfmt (cargo +nightly fmt). A lot of the rustfmt.toml features depend on nightly toolchain. It would be ideal if they weren't nightly-exclusive features, but they currently still are. CI's rustfmt uses nightly.

If you need to allow a lint, please make sure it's either obvious as to why (e.g. clippy saying redundant clone but it's actually required) or it has a comment saying why. Do not write inefficient code for the sake of satisfying lints. If a lint is wrong and provides a more inefficient solution or suggestion, allow the lint and mention that in a comment.

Pre-commit Checks

Continuwuity uses pre-commit hooks to enforce various coding standards and catch common issues before they're committed. These checks include:

• Code formatting and linting
• Typo detection (both in code and commit messages)
• Checking for large files
• Ensuring proper line endings and no trailing whitespace
• Validating YAML, JSON, and TOML files
• Checking for merge conflicts

You can run these checks locally by installing prefligit:

# Install prefligit using cargo-binstall
cargo binstall prefligit

# Install git hooks to run checks automatically
prefligit install

# Run all checks
prefligit --all-files

Alternatively, you can use pre-commit:

# Install pre-commit
pip install pre-commit

# Install the hooks
pre-commit install

# Run all checks manually
pre-commit run --all-files

These same checks are run in CI via the prefligit-checks workflow to ensure consistency.

Running tests locally

Tests, compilation, and linting can be run with standard Cargo commands:

# Run tests
cargo test

# Check compilation
cargo check --workspace

# Run lints
cargo clippy --workspace
# Auto-fix: cargo clippy --workspace --fix --allow-staged;

# Format code (must use nightly)
cargo +nightly fmt

Matrix tests

Continuwuity uses Complement for Matrix protocol compliance testing. Complement tests are run manually by developers, and documentation on how to run these tests locally is currently being developed.

If your changes are done to fix Matrix tests, please note that in your pull request. If more Complement tests start failing from your changes, please review the logs and determine if they're intended or not.

Sytest is currently unsupported.

Writing documentation

Continuwuity's website uses mdbook and is deployed via CI using Cloudflare Pages in the documentation.yml workflow file. All documentation is in the docs/ directory at the top level.

To build the documentation locally:

1. Install mdbook if you don't have it already:

   cargo install mdbook # or cargo binstall, or another method
   

2. Build the documentation:

   mdbook build
   

The output of the mdbook generation is in public/. You can open the HTML files directly in your browser without needing a web server.

Inclusivity and Diversity

All MUST code and write with inclusivity and diversity in mind. See the following page by Google on writing inclusive code and documentation.

This EXPLICITLY forbids usage of terms like "blacklist"/"whitelist" and "master"/"slave", forbids gender-specific words and phrases, forbids ableist language like "sanity-check", "cripple", or "insane", and forbids culture-specific language (e.g. US-only holidays or cultures).

No exceptions are allowed. Dependencies that may use these terms are allowed but do not replicate the name in your functions or variables.

In addition to language, write and code with the user experience in mind. This is software that intends to be used by everyone, so make it easy and comfortable for everyone to use. 🏳️‍⚧️

Variable, comment, function, etc standards

Rust's default style and standards with regards to function names, variable names, comments, etc applies here.

Commit Messages

Continuwuity follows the Conventional Commits specification for commit messages. This provides a standardized format that makes the commit history more readable and enables automated tools to generate changelogs.

The basic structure is:

<type>[(optional scope)]: <description>

[optional body]

[optional footer(s)]

The allowed types for commits are:

• fix: Bug fixes
• feat: New features
• docs: Documentation changes
• style: Changes that don't affect the meaning of the code (formatting, etc.)
• refactor: Code changes that neither fix bugs nor add features
• perf: Performance improvements
• test: Adding or fixing tests
• build: Changes to the build system or dependencies
• ci: Changes to CI configuration
• chore: Other changes that don't modify source or test files

Examples:

feat: add user authentication
fix(database): resolve connection pooling issue
docs: update installation instructions

The project uses the committed hook to validate commit messages in pre-commit. This ensures all commits follow the conventional format.

Creating pull requests

Please try to keep contributions to the Forgejo Instance. While the mirrors of continuwuity allow for pull/merge requests, there is no guarantee the maintainers will see them in a timely manner. Additionally, please mark WIP or unfinished or incomplete PRs as drafts. This prevents us from having to ping once in a while to double check the status of it, especially when the CI completed successfully and everything so it looks done.

Before submitting a pull request, please ensure:

1. Your code passes all CI checks (formatting, linting, typo detection, etc.)
2. Your commit messages follow the conventional commits format
3. Tests are added for new functionality
4. Documentation is updated if needed

Direct all PRs/MRs to the main branch.

By sending a pull request or patch, you are agreeing that your changes are allowed to be licenced under the Apache-2.0 licence and all of your conduct is in line with the Contributor's Covenant, and continuwuity's Code of Conduct.

Contribution by users who violate either of these code of conducts may not have their contributions accepted. This includes users who have been banned from continuwuity Matrix rooms for Code of Conduct violations.

Testing

Complement

Have a look at Complement's repository for an explanation of what it is.

To test against Complement, with Nix (or Lix and direnv installed and set up (run direnv allow after setting up the hook), you can:

• Run ./bin/complement "$COMPLEMENT_SRC" to build a Complement image, run the tests, and output the logs and results to the specified paths. This will also output the OCI image at result
• Run nix build .#complement from the root of the repository to just build a Complement OCI image outputted to result (it's a .tar.gz file)
• Or download the latest Complement OCI image from the CI workflow artifacts output from the commit/revision you want to test (e.g. from main) here

If you want to use your own prebuilt OCI image (such as from our CI) without needing Nix installed, put the image at complement_oci_image.tar.gz in the root of the repo and run the script.

If you're on macOS and need to build an image, run nix build .#linux-complement.

We have a Complement fork as some tests have needed to be fixed. This can be found at: https://forgejo.ellis.link/continuwuation/complement

Hot Reloading ("Live" Development)

Note that hot reloading has not been refactored in quite a while and is not guaranteed to work at this time.

Summary

When developing in debug-builds with the nightly toolchain, Continuwuity is modular using dynamic libraries and various parts of the application are hot-reloadable while the server is running: http api handlers, admin commands, services, database, etc. These are all split up into individual workspace crates as seen in the src/ directory. Changes to sourcecode in a crate rebuild that crate and subsequent crates depending on it. Reloading then occurs for the changed crates.

Release builds still produce static binaries which are unaffected. Rust's soundness guarantees are in full force. Thus you cannot hot-reload release binaries.

Requirements

Currently, this development setup only works on x86_64 and aarch64 Linux glibc. musl explicitly does not support hot reloadable libraries, and does not implement dlclose. macOS does not fully support our usage of RTLD_GLOBAL possibly due to some thread-local issues. This Rust issue may be of relevance, specifically this comment. It may be possible to get it working on only very modern macOS versions such as at least Sonoma, as currently loading dylibs is supported, but not unloading them in our setup, and the cited comment mentions an Apple WWDC confirming there have been TLS changes to somewhat make this possible.

As mentioned above this requires the nightly toolchain. This is due to reliance on various Cargo.toml features that are only available on nightly, most specifically RUSTFLAGS in Cargo.toml. Some of the implementation could also be simpler based on other various nightly features. We hope lots of nightly features start making it out of nightly sooner as there have been dozens of very helpful features that have been stuck in nightly ("unstable") for at least 5+ years that would make this simpler. We encourage greater community consensus to move these features into stability.

This currently only works on x86_64/aarch64 Linux with a glibc C library. musl C library, macOS, and likely other host architectures are not supported (if other architectures work, feel free to let us know and/or make a PR updating this). This should work on GNU ld and lld (rust-lld) and gcc/clang, however if you happen to have linker issues it's recommended to try using mold or gold linkers, and please let us know in the Continuwuity Matrix room the linker error and what linker solved this issue so we can figure out a solution. Ideally there should be minimal friction to using this, and in the future a build script (build.rs) may be suitable to making this easier to use if the capabilities allow us.

Usage

As of 19 May 2024, the instructions for using this are:

0. Have patience. Don't hesitate to join the Continuwuity Matrix room to receive help using this. As indicated by the various rustflags used and some of the interesting issues linked at the bottom, this is definitely not something the Rust ecosystem or toolchain is used to doing.

1. Install the nightly toolchain using rustup. You may need to use rustup override set nightly in your local Continuwuity directory, or use cargo +nightly for all actions.

2. Uncomment cargo-features at the top level / root Cargo.toml

3. Scroll down to the # Developer profile section and uncomment ALL the rustflags for each dev profile and their respective packages.

4. In each workspace crate's Cargo.toml (everything under src/* AND deps/rust-rocksdb/Cargo.toml), uncomment the dylib crate type under [lib].

5. Due to this rpath issue, you must export the LD_LIBRARY_PATH environment variable to your nightly Rust toolchain library directory. If using rustup (hopefully), use this: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/

6. Start the server. You can use cargo +nightly run for this along with the standard.

7. Make some changes where you need to.

8. In a separate terminal window in the same directory (or using a terminal multiplexer like tmux), run the build Cargo command cargo +nightly build. Cargo should only rebuild what was changed / what's necessary, so it should not be rebuilding all the crates.

9. In your Continuwuity server terminal, hit/send CTRL+C signal. This will tell Continuwuity to find which libraries need to be reloaded, and reloads them as necessary.

10. If there were no errors, it will tell you it successfully reloaded # modules, and your changes should now be visible. Repeat 7 - 9 as needed.

To shutdown Continuwuity in this setup, hit/send CTRL+\. Normal builds still shutdown with CTRL+C as usual.

Steps 1 - 5 are the initial first-time steps for using this. To remove the hot reload setup, revert/comment all the Cargo.toml changes.

As mentioned in the requirements section, if you happen to have some linker issues, try using the -fuse-ld= rustflag and specify mold or gold in all the rustflags definitions in the top level Cargo.toml, and please let us know in the Continuwuity Matrix room the problem. mold can be installed typically through your distro, and gold is provided by the binutils package.

It's possible a helper script can be made to do all of this, or most preferably a specially made build script (build.rs). cargo watch support will be implemented soon which will eliminate the need to manually run cargo build all together.

Addendum

Conduit was inherited as a single crate without modularity or reloading in its design. Reasonable partitioning and abstraction allowed a split into several crates, though many circular dependencies had to be corrected. The resulting crates now form a directed graph as depicted in figures below. The interfacing between these crates is still extremely broad which is not mitigable.

Initially hot_lib_reload was investigated but found appropriate for a project designed with modularity through limited interfaces, not a large and complex existing codebase. Instead a bespoke solution built directly on libloading satisfied our constraints. This required relatively minimal modifications and zero maintenance burden compared to what would be required otherwise. The technical difference lies with relocation processing: we leverage global bindings (RTLD_GLOBAL) in a very intentional way. Most libraries and off-the-shelf module systems (such as hot_lib_reload) restrict themselves to local bindings (RTLD_LOCAL). This allows them to release software to multiple platforms with much greater consistency, but at the cost of burdening applications to explicitly manage these bindings. In our case with an optional feature for developers, we shrug any such requirement to enjoy the cost/benefit on platforms where global relocations are properly cooperative.

To make use of RTLD_GLOBAL the application has to be oriented as a directed acyclic graph. The primary rule is simple and illustrated in the figure below: no crate is allowed to call a function or use a variable from a crate below it.

When a symbol is referenced between crates they become bound: crates cannot be unloaded until their calling crates are first unloaded. Thus we start the reloading process from the crate which has no callers. There is a small problem though: the first crate is called by the base executable itself! This is solved by using an RTLD_LOCAL binding for just one link between the main executable and the first crate, freeing the executable from all modules as no global binding ever occurs between them.

Proper resource management is essential for reliable reloading to occur. This is a very basic ask in RAII-idiomatic Rust and the exposure to reloading hazards is remarkably low, generally stemming from poor patterns and practices. Unfortunately static analysis doesn't enforce reload-safety programmatically (though it could one day), for now hazards can be avoided by knowing a few basic do's and dont's:

1. Understand that code is memory. Just like one is forbidden from referencing free'd memory, one must not transfer control to free'd code. Exposure to this is primarily from two things:

   • Callbacks, which this project makes very little use of.
   • Async tasks, which are addressed below.

2. Tie all resources to a scope or object lifetime with greatest possible symmetry (locality). For our purposes this applies to code resources, which means async blocks and tokio tasks.

   • Never spawn a task without receiving and storing its JoinHandle.
   • Always wait on join handles before leaving a scope or in another cleanup function called by an owning scope.

3. Know any minor specific quirks documented in code or here:

   • Don't use tokio::spawn, instead use our Handle in core/server.rs, which is reachable in most of the codebase via services() or other state. This is due to some bugs or assumptions made in tokio, as it happens in unsafe {} blocks, which are mitigated by circumventing some thread-local variables. Using runtime handles is good practice in any case.

The initial implementation PR is available here.

Continuwuity Community Guidelines

Welcome to the Continuwuity commuwunity! We're excited to have you here. Continuwuity is a continuation of the conduwuit homeserver, which in turn is a hard-fork of the Conduit homeserver, aimed at making Matrix more accessible and inclusive for everyone.

This space is dedicated to fostering a positive, supportive, and welcoming environment for everyone. These guidelines apply to all Continuwuity spaces, including our Matrix rooms and any other community channels that reference them. We've written these guidelines to help us all create an environment where everyone feels safe and respected.

For code and contribution guidelines, please refer to the Contributor's Covenant. Below are additional guidelines specific to the Continuwuity community.

Our Values and Expected Behaviors

We strive to create a community based on mutual respect, collaboration, and inclusivity. We expect all members to:

1. Be Respectful and Inclusive: Treat everyone with respect. We're committed to a community where everyone feels safe, regardless of background, identity, or experience. Discrimination, harassment, or hate speech won't be tolerated. Remember that each person experiences the world differently; share your own perspective and be open to learning about others'.

2. Be Positive and Constructive: Engage in discussions constructively and support each other. If you feel angry or frustrated, take a break before participating. Approach disagreements with the goal of understanding, not winning. Focus on the issue, not the person.

3. Communicate Clearly and Kindly: Our community includes neurodivergent individuals and those who may not appreciate sarcasm or subtlety. Communicate clearly and kindly. Avoid ambiguity and ensure your messages can be easily understood by all. Avoid placing the burden of education on marginalized groups; please make an effort to look into your questions before asking others for detailed explanations.

4. Be Open to Improving Inclusivity: Actively participate in making our community more inclusive. Report behaviour that contradicts these guidelines (see Reporting and Enforcement below) and be open to constructive feedback aimed at improving our community. Understand that discussing negative experiences can be emotionally taxing; focus on the message, not the tone.

5. Commit to Our Values: Building an inclusive community requires ongoing effort from everyone. Recognise that addressing bias and discrimination is a continuous process that needs commitment and action from all members.

Unacceptable Behaviors

To ensure everyone feels safe and welcome, the following behaviors are considered unacceptable within the Continuwuity community:

• Harassment and Discrimination: Avoid offensive comments related to background, family status, gender, gender identity or expression, marital status, sex, sexual orientation, native language, age, ability, race and/or ethnicity, caste, national origin, socioeconomic status, religion, geographic location, or any other dimension of diversity. Don't deliberately misgender someone or question the legitimacy of their gender identity.

• Violence and Threats: Do not engage in any form of violence or threats, including inciting violence towards anyone or encouraging self-harm. Posting or threatening to post someone else's personally identifying information ("doxxing") is also forbidden.

• Personal Attacks: Disagreements happen, but they should never turn into personal attacks. Don't insult, demean, or belittle others.

• Unwelcome Attention or Contact: Avoid unwelcome sexual attention, inappropriate physical contact (or simulation thereof), sexualized comments, jokes, or imagery.

• Disruption: Do not engage in sustained disruption of discussions, events, or other community activities.

• Bad Faith Actions: Do not intentionally make false reports or otherwise abuse the reporting process.

This is not an exhaustive list. Any behaviour that makes others feel unsafe or unwelcome may be subject to enforcement action.

Matrix Community

These Community Guidelines apply to the entire Continuwuity Matrix Space and its rooms, including:

#continuwuity:continuwuity.org

This room is for support and discussions about Continuwuity. Ask questions, share insights, and help each other out while adhering to these guidelines.

We ask that this room remain focused on the Continuwuity software specifically: the team are typically happy to engage in conversations about related subjects in the off-topic room.

#offtopic:continuwuity.org

For off-topic community conversations about any subject. While this room allows for a wide range of topics, the same guidelines apply. Please keep discussions respectful and inclusive, and avoid divisive or stressful subjects like specific country/world politics unless handled with exceptional care and respect for diverse viewpoints.

General topics, such as world events, are welcome as long as they follow the guidelines. If a member of the team asks for the conversation to end, please respect their decision.

#dev:continuwuity.org

This room is dedicated to discussing active development of Continuwuity, including ongoing issues or code development. Collaboration here must follow these guidelines, and please consider raising an issue on the repository to help track progress.

Reporting and Enforcement

We take these Community Guidelines seriously to protect our community members. If you witness or experience unacceptable behaviour, or have any other concerns, please report it.

How to Report:

• Alert Moderators in the Room: If you feel comfortable doing so, you can address the issue publicly in the relevant room by mentioning the moderation bot, @rock:continuwuity.org, which will immediately alert all available moderators.
• Direct Message: If you're not comfortable raising the issue publicly, please send a direct message (DM) to one of the room moderators.

Reports will be handled with discretion. We will investigate promptly and thoroughly.

Enforcement Actions:

Anyone asked to stop unacceptable behaviour is expected to comply immediately. Failure to do so, or engaging in prohibited behaviour, may result in enforcement action. Moderators may take actions they deem appropriate, including but not limited to:

1. Warning: A direct message or public warning identifying the violation and requesting corrective action.
2. Temporary Mute: Temporary restriction from participating in discussions for a specified period.
3. Kick or Ban: Removal from a room (kick) or the entire community space (ban). Egregious or repeated violations may result in an immediate ban. Bans are typically permanent and reviewed only in exceptional circumstances.

Retaliation against those who report concerns in good faith will not be tolerated and will be subject to the same enforcement actions.

Together, let's build and maintain a community where everyone feels valued, safe, and respected.

— The Continuwuity Moderation Team
