conduwuit

a very cool, featureful fork of Conduit

What is Matrix?

Matrix is an open network for secure and decentralized communication. Users from every Matrix homeserver can chat with users from all other Matrix servers. You can even use bridges (also called Matrix Appservices) to communicate with users outside of Matrix, like a community on Discord.

What is the goal?

A high-performance and efficient Matrix homeserver that's easy to set up and just works. You can install it on a mini-computer like the Raspberry Pi to host Matrix for your family, friends or company.

Can I try it out?

An official conduwuit server ran by me is available at transfem.dev (element.transfem.dev / cinny.transfem.dev)

transfem.dev is a public homeserver that can be used, it is not a "test only homeserver". This means there are rules, so please read the rules: https://transfem.dev/homeserver_rules.txt

transfem.dev is also listed at servers.joinmatrix.org

What is the current status?

conduwuit is technically a hard fork of Conduit, which is in Beta. The Beta status initially was inherited from Conduit, however overtime this Beta status is rapidly becoming less and less relevant as our codebase significantly diverges more and more.

conduwuit is quite stable and very usable as a daily driver and for a low-medium sized homeserver. There is still a lot of more work to be done, but it is in a far better place than the project was in early 2024.

How is conduwuit funded? Is conduwuit sustainable?

conduwuit has no external funding. This is made possible purely in my freetime with contributors, also in their free time, and only by user-curated donations.

conduwuit has existed since around November 2023, but only became more publicly known in March/April 2024 and we have no plans in stopping or slowing down any time soon!

Can I migrate or switch from Conduit?

conduwuit is a complete drop-in replacement for Conduit. As long as you are using RocksDB, the only "migration" you need to do is replace the binary or container image. There is no harm or additional steps required for using conduwuit. See the Migrating from Conduit section on the generic deploying guide.

Note that as of conduwuit version 0.5.0, backwards compatibility with Conduit is no longer supported. We only support migrating from Conduit, not back to Conduit like before. If you are truly finding yourself wanting to migrate back to Conduit, we would appreciate all your feedback and if we can assist with any issues or concerns.

What's different about your fork than upstream Conduit?

list of features, bug fixes, etc that conduwuit does that Conduit does not

Outgoing typing indicators, outgoing read receipts, and outgoing presence!

Performance

• Concurrency support for individual homeserver key fetching for faster remote room joins and room joins that will error less frequently
• Send Cache-Control response header with immutable and 1 year cache length for all media requests (download and thumbnail) to instruct clients to cache media, and reduce server load from media requests that could be otherwise cached
• Add feature flags and config options to enable/build with zstd, brotli, and/or gzip HTTP body compression (response and request)
• Eliminate all usage of the thread-blocking getaddrinfo(3) call upon DNS queries, significantly improving federation latency/ping and cache DNS results (NXDOMAINs, successful queries, etc) using hickory-dns / hickory-resolver
• Enable HTTP/2 support on all requests
• Vastly improve RocksDB default settings to use new features that help with performance significantly, uses settings tailored to SSDs, various ways to tweak RocksDB, and a conduwuit setting to tell RocksDB to use settings that are tailored to HDDs or slow spinning rust storage or buggy filesystems.
• Implement database flush and cleanup conduwuit operations when using RocksDB
• Implement RocksDB write buffer corking and coalescing in database write-heavy areas
• Perform connection pooling and keepalives where necessary to significantly improve federation performance and latency
• Various config options to tweak connection pooling, request timeouts, connection timeouts, DNS timeouts and settings, etc with good defaults which also help huge with performance via reusing connections and retrying where needed
• Properly get and use the amount of parallelism / tokio workers
• Implement building conduwuit with jemalloc (which extends to the RocksDB jemalloc feature for maximum gains) or hardened_malloc light variant, and io_uring support, and produce CI builds with jemalloc and io_uring by default for performance (Nix doesn't seem to build hardened_malloc-rs properly)
• Add support for caching DNS results with hickory-dns / hickory-resolver in conduwuit (not a replacement for a proper resolver cache, but still far better than nothing), also properly falls back on TCP for UDP errors or if a SRV response is too large
• Add config option for using DNS over TCP, and config option for controlling A/AAAA record lookup strategy (e.g. don't query AAAA records if you don't have IPv6 connectivity)
• Overall significant database, Client-Server, and federation performance and latency improvements (check out the ping room leaderboards if you don't believe me :>)
• Add config options for RocksDB compression and bottommost compression, including choosing the algorithm and compression level
• Use loole MPSC channels instead of tokio MPSC channels for huge performance boosts in sending channels (mainly relevant for federation) and presence channels
• Use tracing/log's release_max_level_info feature to improve performance, build speeds, binary size, and CPU usage in release builds by avoid compiling debug/trace log level macros that users will generally never use (can be disabled with a build-time feature flag)
• Remove some unnecessary checks on EDU handling for incoming transactions, effectively speeding them up
• Simplify, dedupe, etc huge chunks of the codebase, including some that were unnecessary overhead, binary bloats, or preventing compiler/linker optimisations
• Implement zero-copy RocksDB database accessors, substantially improving performance caused by unnecessary memory allocations

General Fixes/Features

• Add legacy Element client hack fixing password changes and deactivations on legacy Element Android/iOS due to usage of an unspecced user field for UIAA
• Raise and improve all the various request timeouts making some things like room joins and client bugs error less or none at all than they should, and make them all user configurable
• Add missing reason field to user ban events (/ban)
• Safer and cleaner shutdowns across incoming/outgoing requests (graceful shutdown) and the database
• Stop sending make_join requests on room joins if 15 servers respond with M_UNSUPPORTED_ROOM_VERSION or M_INVALID_ROOM_VERSION
• Stop sending make_join requests if 50 servers cannot provide make_join for us
• Respect most client parameters for /media/ requests (allow_redirect still needs work)
• Return joined member count of rooms for push rules/conditions instead of a hardcoded value of 10
• Make CONDUIT_CONFIG optional, relevant for container users that configure only by environment variables and no longer need to set CONDUIT_CONFIG to an empty string.
• Allow HEAD and PATCH (MSC4138) HTTP requests in CORS for clients (despite not being explicity mentioned in Matrix spec, HTTP spec says all HEAD requests need to behave the same as GET requests, Synapse supports HEAD requests)
• Fix using conduwuit with flake-compat on NixOS
• Resolve and remove some "features" from upstream that result in concurrency hazards, exponential backoff issues, or arbitrary performance limiters
• Find more servers for outbound federation /hierarchy requests instead of just the room ID server name
• Support for suggesting servers to join through at /_matrix/client/v3/directory/room/{roomAlias}
• Support for suggesting servers to join through us at /_matrix/federation/v1/query/directory
• Misc edge-case search fixes (e.g. potentially missing some events)
• Misc /sync fixes (e.g. returning unnecessary data or incorrect/invalid responses)
• Add replaces_state and prev_sender in unsigned for state event changes which primarily makes Element's "See history" button on a state event functional
• Fix Conduit not allowing incoming federation requests for various world readable rooms
• Fix Conduit not respecting the client-requested file name on media requests
• Prevent sending junk / non-membership events to /send_join and /send_leave endpoints
• Only allow the requested membership type on /send_join and /send_leave endpoints (e.g. don't allow leave memberships on join endpoints)
• Prevent state key impersonation on /send_join and /send_leave endpoints
• Validate X-Matrix origin and request body "origin" field on incoming transactions
• Add GET /_matrix/client/v1/register/m.login.registration_token/validity endpoint
• Explicitly define support for sliding sync at /_matrix/client/versions (org.matrix.msc3575)
• Fix seeing empty status messages on user presences

Moderation

• (Also see Admin Room for all the admin commands pertaining to moderation, there's a lot!)
• Add support for room banning/blocking by ID using admin command
• Add support for serving support well-known from [global.well_known] (MSC1929) (/.well-known/matrix/support)
• Config option to forbid publishing rooms to the room directory (lockdown_public_room_directory) except for admins
• Admin commands to delete room aliases and unpublish rooms from our room directory
• For all /report requests: check if the reported event ID belongs to the reported room ID, raise report reasoning character limit to 750, fix broken formatting, make a small delayed random response per spec suggestion on privacy, and check if the sender user is in the reported room.
• Support blocking servers from downloading remote media from, returning a 404
• Don't allow m.call.invite events to be sent in public rooms (prevents calling the entire room)
• On new public room creations, only allow moderators to send m.call.invite, org.matrix.msc3401.call, and org.matrix.msc3401.call.member events to prevent unprivileged users from calling the entire room
• Add support for a "global ACLs" feature (forbidden_remote_server_names) that blocks inbound remote room invites, room joins by room ID on server name, room joins by room alias on server name, incoming federated joins, and incoming federated room directory requests. This is very helpful for blocking servers that are purely toxic/bad and serve no value in allowing our users to suffer from things like room invite spam or such. Please note that this is not a substitute for room ACLs.
• Add support for a config option to forbid our local users from sending federated room directory requests for (forbidden_remote_room_directory_server_names). Similar to above, useful for blocking servers that help prevent our users from wandering into bad areas of Matrix via room directories of those malicious servers.
• Add config option for auto remediating/deactivating local non-admin users who attempt to join bad/forbidden rooms (auto_deactivate_banned_room_attempts)
• Deactivating users will remove their profile picture, blurhash, display name, and leave all rooms by default just like Synapse and for additional privacy
• Reject some EDUs from ACL'd users such as read receipts and typing indicators

Privacy/Security

• Add config option for device name federation with a privacy-friendly default (disabled)

• Generate passwords with 25 characters instead of 15
• Config option ip_range_denylist to support refusing to send requests (typically federation) to specific IP ranges, typically RFC 1918, non-routable, testnet, etc addresses like Synapse for security (note: this is not a guaranteed protection, and you should be using a firewall with zones if you want guaranteed protection as doing this on the application level is prone to bypasses).
• Config option to block non-admin users from sending room invites or receiving remote room invites. Admin users are still allowed.
• Config option to disable incoming and/or outgoing remote read receipts
• Config option to disable incoming and/or outgoing remote typing indicators
• Config option to disable incoming, outgoing, and/or local presence and for timing out remote users
• Sanitise file names for the Content-Disposition header for all media requests (thumbnails, downloads, uploads)
• Media repository on handling Content-Disposition and Content-Type is fully spec compliant and secured
• Send secure default HTTP headers such as a strong restrictive CSP (see MSC4149), deny iframes, disable X-XSS-Protection, disable interest cohort in Permission-Policy, etc to mitigate any potential attack surface such as from untrusted media

Administration/Logging

• Commandline argument to specify the path to a config file instead of relying on CONDUIT_CONFIG
• Revamped admin room infrastructure and commands
• Substantially clean up, improve, and fix logging (less noisy dead server logging, registration attempts, more useful troubleshooting logging, proper error propagation, etc)
• Configurable RocksDB logging (LOG files) with proper defaults (rotate, max size, verbosity, etc) to stop LOG files from accumulating so much
• Explicit startup error if your configuration allows open registration without a token or such like Synapse with a way to bypass it if needed
• Replace the lightning bolt emoji option with support for setting any arbitrary text (e.g. another emoji) to suffix to all new user registrations, with a conduwuit default of "🏳️‍⚧️"
• Implement config option to auto join rooms upon registration
• Warn on unknown config options specified
• Add /_conduwuit/server_version route to return the version of conduwuit without relying on the federation API /_matrix/federation/v1/version
• Add /_conduwuit/local_user_count route to return the amount of registered active local users on your homeserver if federation is enabled
• Add configurable RocksDB recovery modes to aid in recovering corrupted RocksDB databases
• Support config options via CONDUWUIT_ prefix and accessing non-global struct config options with the __ split (e.g. CONDUWUIT_WELL_KNOWN__SERVER)
• Add support for listening on multiple TCP ports and multiple addresses
• Opt-in Sentry.io telemetry and metrics, mainly used for crash reporting
• Log the client IP on various requests such as registrations, banned room join attempts, logins, deactivations, federation transactions, etc
• Fix Conduit dropping some remote server federation response errors

Maintenance/Stability

• Add static and dynamic linking smoke tests in CI to prevent any potential linking regressions for Complement, static binaries, Nix devshells, etc
• Add timestamp by commit date when building OCI images for keeping image build reproducibility and still have a meaningful "last modified date" for OCI image
• Add timestamp by commit date via SOURCE_DATE_EPOCH for Debian packages
• Startup check if conduwuit running in a container and is listening on 127.0.0.1 (generally containers are using NAT networking and 0.0.0.0 is the intended listening address)
• Add a panic catcher layer to return panic messages in HTTP responses if a panic occurs
• Add full compatibility support for SHA256 media file names instead of base64 file names to overcome filesystem file name length limitations (OS error file name too long) while still retaining upstream database compatibility
• Remove SQLite support due to being very poor performance, difficult to maintain against RocksDB, and is a blocker to significantly improved database code

Admin Room

• Add admin command to return a room's full/complete state
• Admin debug command to fetch a PDU from a remote server and inserts it into our database/timeline as backfill
• Add admin command to delete media via a specific MXC. This deletes the MXC from our database, and the file locally.

Configuration

This chapter describes various ways to configure conduwuit.

Basics

conduwuit 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 conduwuit 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

conduwuit 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

conduwuit 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).

# The server_name is the pretty name of this server. It is used as a
# suffix for user and room IDs/aliases.
#
# See the docs for reverse proxying and delegation: https://conduwuit.puppyirl.gay/deploying/generic.html#setting-up-the-reverse-proxy
# Also see the `[global.well_known]` config section at the very bottom.

#
# example: "conduwuit.woof"
#
#server_name =

# default address (IPv4 or IPv6) conduwuit will listen on.
#
# If you are using Docker or a container NAT networking setup, this must
# be "0.0.0.0".
#
# To listen on multiple addresses, specify a vector e.g. ["127.0.0.1",
# "::1"]
#
#address = ["127.0.0.1", "::1"]

# The port(s) conduwuit will be running on.
#
# See https://conduwuit.puppyirl.gay/deploying/generic.html#setting-up-the-reverse-proxy for reverse proxying.
#
# Docker users: Don't change this, you'll need to map an external port to
# this.
#
# To listen on multiple ports, specify a vector e.g. [8080, 8448]
#
#port = 8008

# Uncomment unix_socket_path to listen on a UNIX socket at the specified
# path. If listening on a UNIX socket, you MUST remove/comment the
# 'address' key if definedm AND add your reverse proxy to the 'conduwuit'
# group, unless world RW permissions are specified with unix_socket_perms
# (666 minimum).
#
# example: "/run/conduwuit/conduwuit.sock"
#
#unix_socket_path =

# The default permissions (in octal) to create the UNIX socket with.
#
#unix_socket_perms = 660

# This is the only directory where conduwuit will save its data, including

#
# YOU NEED TO EDIT THIS.
#
# example: "/var/lib/conduwuit"
#
#database_path =

# conduwuit supports online database backups using RocksDB's Backup engine
# API. To use this, set a database backup path that conduwuit can write
# to.
#
# See https://conduwuit.puppyirl.gay/maintenance.html#backups for more information.
#
# example: "/opt/conduwuit-db-backups"
#
#database_backup_path =

# The amount of online RocksDB database backups to keep/retain, if using
# "database_backup_path", before deleting the oldest one.
#
#database_backups_to_keep = 1

# Set this to any float value in megabytes for conduwuit to tell the
# database engine that this much memory is available for database-related
# caches.
#
# May be useful if you have significant memory to spare to increase
# performance.
#
# Similar to the individual LRU caches, this is scaled up with your CPU
# core count.
#
# This defaults to 128.0 + (64.0 * CPU core count)
#
#db_cache_capacity_mb = varies by system

# Option to control adding arbitrary text to the end of the user's
# displayname upon registration with a space before the text. This was the
# lightning bolt emoji option, just replaced with support for adding your
# own custom text or emojis. To disable, set this to "" (an empty string).
#
# The default is the trans pride flag.
#
# example: "🏳️‍⚧️"
#
#new_user_displayname_suffix = "🏳️‍⚧️"

# If enabled, conduwuit will send a simple GET request periodically to
# `https://pupbrain.dev/check-for-updates/stable` for any new
# announcements made. Despite the name, this is not an update check
# endpoint, it is simply an announcement check endpoint.
#
# This is disabled by default as this is rarely used except for security
# updates or major updates.
#
#allow_check_for_updates = false

# Set this to any float value to multiply conduwuit's in-memory LRU caches

Deploying

This chapter describes various ways to deploy conduwuit.

Generic deployment documentation

Getting help

If you run into any problems while setting up conduwuit, ask us in #conduwuit:puppygock.gay or open an issue on GitHub.

Installing conduwuit

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.

Binaries are also available on my website directly at: https://pup.systems/~strawberry/conduwuit/

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 conduwuit 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 conduwuit using cargo build --release --all-features

Migrating from Conduit

As mentioned in the README, there is little to no steps needed to migrate from Conduit. As long as you are using the RocksDB database backend, just replace the binary / container image / etc.

WARNING: As of conduwuit 0.5.0, all database and backwards compatibility with Conduit is no longer supported. We only support migrating from Conduit, not back to Conduit like before. If you are truly finding yourself wanting to migrate back to Conduit, we would appreciate all your feedback and if we can assist with any issues or concerns.

Note: If you are relying on Conduit's "automatic delegation" feature, this will NOT work on conduwuit and you must configure delegation manually. This is not a mistake and no support for this feature will be added.

If you are using SQLite, you MUST migrate to RocksDB. You can use this tool to migrate from SQLite to RocksDB: https://github.com/ShadowJonathan/conduit_toolbox/

See the [global.well_known] config section, or configure your web server appropriately to send the delegation responses.

Adding a conduwuit user

While conduwuit 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 conduwuit user:

sudo adduser --system conduwuit --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 conduwuit

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. conduwuit 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 conduwuit 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 conduwuit can be found on the configuration page. You may need to change the ExecStart= path to where you placed the conduwuit 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 conduwuit configuration file

Now we need to create the conduwuit's config file in /etc/conduwuit/conduwuit.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 conduwuit, 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 conduwuit:conduwuit /var/lib/conduwuit/
sudo chmod 700 /var/lib/conduwuit/

Setting up the Reverse Proxy

Refer to the documentation or various guides online of your chosen reverse proxy software. There are many examples of basic Apache/Nginx reverse proxy setups out there.

A Caddy example will be provided as this is the recommended reverse proxy for new users and is very trivial to use (handles TLS, reverse proxy headers, etc transparently with proper defaults).

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 this (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 conduwuit 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 will need to reverse proxy everything under following routes:

• /_matrix/ - core Matrix C-S and S-S APIs
• /_conduwuit/ - ad-hoc conduwuit 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 conduwuit to perform delegation (see the [global.well_known] config section)
• /.well-known/matrix/support if using conduwuit 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

Caddy

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
    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

You're done

Now you can start conduwuit 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.

conduwuit for NixOS

conduwuit 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 conduwuit's binary cache

A community maintained NixOS package is available at conduwuit

Binary cache

A binary cache for conduwuit that the CI/CD publishes to is available at the following places (both are the same just different names):

https://attic.kennel.juneis.dog/conduit
conduit:eEKoUwlQGDdYmAI/Q/0slVlegqh/QmAvQd7HBSm21Wk=

https://attic.kennel.juneis.dog/conduwuit
conduwuit:BbycGUgTISsltcmH0qNjFR9dbrQNYgdIAcmViSGoVTE=

The binary caches were recreated some months ago due to attic issues. The old public keys were:

conduit:Isq8FGyEC6FOXH6nD+BOeAA+bKp6X6UIbupSlGEPuOg=
conduwuit:lYPVh7o1hLu1idH4Xt2QHaRa49WRGSAqzcfFd94aOTw=

If needed, we have a binary cache on Cachix but it is only limited to 5GB:

https://conduwuit.cachix.org
conduwuit.cachix.org-1:MFRm6jcnfTf0jSAbmvLfhO3KBMt4px+1xaereWXp8Xg=

If specifying a Git remote URL in your flake, you can use any remotes that are specified on the README (the mirrors), such as the GitHub: github:girlbossceo/conduwuit

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 conduwuit.

Conduit NixOS Config Module and SQLite

Beware! The services.matrix-conduit module defaults to SQLite as a database backend. Conduwuit 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 conduwuit from the flake.nix or default.nix and set services.matrix-conduit.package appropriately to use conduwuit instead of Conduit.

UNIX sockets

Due to the lack of a conduwuit 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 conduwuit NixOS configuration module, developed and published by the community, would be appreciated.

jemalloc and hardened profile

conduwuit 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 conduwuit, or disable jemalloc like so:

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

conduwuit for Docker

Docker

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

Use a registry

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

Registry	Image	Size	Notes
GitHub Registry	ghcr.io/girlbossceo/conduwuit:latest		Stable latest tagged image.
GitLab Registry	registry.gitlab.com/conduwuit/conduwuit:latest		Stable latest tagged image.
Docker Hub	docker.io/girlbossceo/conduwuit:latest		Stable latest tagged image.
GitHub Registry	ghcr.io/girlbossceo/conduwuit:main		Stable main branch.
GitLab Registry	registry.gitlab.com/conduwuit/conduwuit:main		Stable main branch.
Docker Hub	docker.io/girlbossceo/conduwuit:main		Stable main branch.

OCI image .tar.gz files are also hosted directly at when uploaded by CI with a commit hash/revision or a tagged release: https://pup.systems/~strawberry/conduwuit/

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/conduwuit/ \
    -e CONDUWUIT_SERVER_NAME="your.server.name" \
    -e CONDUWUIT_ALLOW_REGISTRATION=false \
    --name conduwuit $LINK

or you can use docker compose.

The -d flag lets the container run in detached mode. You may supply an optional conduwuit.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 conduwuit 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 conduwuit 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 conduwuit can be found here.

Build

Official conduwuit images are built using Nix's buildLayeredImage. This ensures all OCI images are repeatable and reproducible by anyone, keeps the images lightweight, and can be built offline.

This also ensures portability of our images because buildLayeredImage builds OCI images, not Docker images, and works with other container software.

The OCI images are OS-less with only a very minimal environment of the tini init system, CA certificates, and the conduwuit binary. This does mean there is not a shell, but in theory you can get a shell by adding the necessary layers to the layered image. However it's very unlikely you will need a shell for any real troubleshooting.

The flake file for the OCI image definition is at nix/pkgs/oci-image/default.nix.

To build an OCI image using Nix, the following outputs can be built:

• nix build -L .#oci-image (default features, x86_64 glibc)
• nix build -L .#oci-image-x86_64-linux-musl (default features, x86_64 musl)
• nix build -L .#oci-image-aarch64-linux-musl (default features, aarch64 musl)
• nix build -L .#oci-image-x86_64-linux-musl-all-features (all features, x86_64 musl)
• nix build -L .#oci-image-aarch64-linux-musl-all-features (all features, aarch64 musl)

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 conduwuit, 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 conduwuit 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.

conduwuit for Kubernetes

conduwuit 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

Should changes need to be made, please reach out to the maintainer in our Matrix room as this is not maintained/controlled by the conduwuit maintainers.

conduwuit for Arch Linux

Currently conduwuit is only on the Arch User Repository (AUR).

The conduwuit AUR packages are community maintained and are not maintained by conduwuit development team, but the AUR package maintainers are in the Matrix room. Please attempt to verify your AUR package's PKGBUILD file looks fine before asking for support.

• conduwuit - latest tagged conduwuit
• conduwuit-git - latest git conduwuit from main branch
• conduwuit-bin - latest tagged conduwuit static binary

conduwuit 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 conduwuit. 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.

conduwuit for FreeBSD

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

Contributions for getting conduwuit packaged are welcome.

Setting up TURN/STURN

In order to make or receive calls, a TURN server is required. conduwuit 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 conduwuit. See the example config in the TURN section for configuring these and restart conduwuit 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 conduwuit 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 #conduwuit:puppygock.gay or open an issue on GitHub.

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 conduwuit 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. conduwuit will send messages to the appservices and the appservice can send requests to the homeserver. You don't need to restart conduwuit, 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 conduwuit setup

Moderation

conduwuit 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.

conduwuit 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 conduwuit 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 conduwuit 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 conduwuit has already configured to only store up to 3 RocksDB LOG files due to generall 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 conduwuit
• 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 conduwuit again and it should open as normal

If you'd like to do an offline backup, shutdown conduwuit 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 conduwuit 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 conduwuit 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. conduwuit 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. conduwuit 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 conduwuit

Docker users ⚠️

Docker is extremely UX unfriendly. Because of this, a ton of issues or support is actually Docker support, not conduwuit support. We also cannot document the ever-growing list of Docker issues here.

If you intend on asking for support and you are using Docker, PLEASE triple validate your issues are NOT because you have a misconfiguration in your Docker setup.

If there are things like Compose file issues or Dockerhub image issues, those can still be mentioned as long as they're something we can fix.

conduwuit 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>" conduwuit binary argument once to invite yourslf to the admin room on startup
• Use the conduwuit 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 has issues with its default DNS setup that may cause DNS to not be properly functional when running conduwuit, resulting in federation issues. The symptoms of this have shown in 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 conduwuit issue, and is purely a Docker issue. It is not sustainable for heavy DNS activity which is normal for Matrix federation. The workarounds for this are:

• Use DNS over TCP via the config option query_over_tcp_only = true
• Don't use Docker's default DNS setup and instead allow the container to use and communicate with your host's DNS servers (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.

conduwuit 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 conduwuit config.

Raising dns_cache_entries in conduwuit 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 conduwuit 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, conduwuit 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 conduwuit 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 conduwuit 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

conduwuit 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

conduwuit 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

conduwuit 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 conduwuit'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 conduwuit console CLI due to PDU size limits, and is not easy for non-developers to understand.

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.

conduwuit project layout

conduwuit 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 conduwuit 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 conduwuit 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 "conduwuit 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 conduwuit development, we have had to fork some dependencies to support our use-cases in some areas. This ranges from things said upstream project won't accept for any reason, faster-paced development (unresponsive or slow upstream), conduwuit-specific usecases, or lack of time to upstream some things.

• ruma/ruma: https://github.com/girlbossceo/ruwuma - various performance improvements, more features, faster-paced development, better client/server interop hacks upstream won't accept, etc
• facebook/rocksdb: https://github.com/girlbossceo/rocksdb - liburing build fixes and GCC debug build fix
• tikv/jemallocator: https://github.com/girlbossceo/jemallocator - musl builds seem to be broken on upstream, fixes some broken/suspicious code in places, additional safety measures, and support redzones for Valgrind
• zyansheep/rustyline-async: https://github.com/girlbossceo/rustyline-async - tab completion callback and CTRL+\ signal quit event for conduwuit console CLI
• rust-rocksdb/rust-rocksdb: https://github.com/girlbossceo/rust-rocksdb-zaidoon1 - @zaidoon1's fork has quicker updates, more up to date dependencies, etc. Our fork fixes musl build issues, removes unnecessary gtest include, and uses our RocksDB and jemallocator forks.
• tokio-rs/tracing: https://github.com/girlbossceo/tracing - Implements Clone for EnvFilter to support dynamically changing tracing envfilter's alongside other logging/metrics things

Debugging with tokio-console

tokio-console can be a useful tool for debugging and profiling. To make a tokio-console-enabled build of conduwuit, 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 conduwuit when starting it. This was due to tokio-console causing gradual memory leak/usage if left enabled.

Contributing guide

This page is for about contributing to conduwuit. 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 #conduwuit:puppygock.gay, 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 cargo 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.

Running CI tests locally

conduwuit's CI for tests, linting, formatting, audit, etc use engage. engage can be installed from nixpkgs or cargo install engage. conduwuit's Nix flake devshell has the nixpkgs engage with direnv. Use engage --help for more usage details.

To test, format, lint, etc that CI would do, install engage, allow the .envrc file using direnv allow, and run engage.

All of the tasks are defined at the engage.toml file. You can view all of them neatly by running engage list

If you would like to run only a specific engage task group, use just:

• engage just <group>
• Example: engage just lints

If you would like to run a specific engage task in a specific group, use just <GROUP> [TASK]: engage just lints cargo-fmt

The following binaries are used in engage.toml:

• engage
• nix
• direnv
• rustc
• cargo
• cargo-fmt
• rustdoc
• cargo-clippy
• cargo-audit
• cargo-deb
• lychee
• markdownlint-cli
• dpkg

Matrix tests

CI runs Complement, but currently does not fail if results from the checked-in results differ with the new results. If your changes are done to fix Matrix tests, note that in your pull request. If more Complement tests start failing from your changes, please review the logs (they are uploaded as artifacts) and determine if they're intended or not.

If you'd like to run Complement locally using Nix, see the testing page.

Sytest support will come soon.

Writing documentation

conduwuit's website uses mdbook and deployed via CI using GitHub Pages in the documentation.yml workflow file with Nix's mdbook in the devshell. All documentation is in the docs/ directory at the top level. The compiled mdbook website is also uploaded as an artifact.

To build the documentation using Nix, run: bin/nix-build-and-cache just .#book

The output of the mdbook generation is in result/. mdbooks can be opened in your browser from the individual HTML files without any web server needed.

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.

Creating pull requests

Please try to keep contributions to the GitHub. While the mirrors of conduwuit allow for pull/merge requests, there is no guarantee I will see them in a timely manner. Additionally, please mark WIP or unfinished or incomplete PRs as drafts. This prevents me 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.

If you open a pull request on one of the mirrors, it is your responsibility to inform me about its existence. In the future I may try to solve this with more repo bots in the conduwuit Matrix room. There is no mailing list or email-patch support on the sr.ht mirror, but if you'd like to email me a git patch you can do so at strawberry@puppygock.gay.

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 conduwuit's Code of Conduct.

Contribution by users who violate either of these code of conducts will not have their contributions accepted. This includes users who have been banned from conduwuit 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, you can:

• Run ./bin/complement "$COMPLEMENT_SRC" ./path/to/logs.jsonl ./path/to/results.jsonl 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

Hot Reloading ("Live" Development)

Summary

When developing in debug-builds with the nightly toolchain, conduwuit 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 conduwuit 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 conduwuit 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 conduwuit 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 conduwuit server terminal, hit/send CTRL+C signal. This will tell conduwuit 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 conduwuit 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 conduwuit 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.
