Add documentation for the new performance-optimised Docker images with
"-maxperf" suffix. These use the release-max-perf build profile with LTO

This fixes a vulnerability where an attacker with a malicious remote
server and a user on the local server can trick the local server into
signing arbitrary events. The attacker issue a remote leave as the local
user to a room on the malicious server. Without any validation of the
make_leave response, the local server would sign the attacker-controlled
event and pass it back to the malicious server with send_leave.
The join and knock endpoints are also fixed in this commit, but are less
useful for exploitation because the local server replaces the "content"
field returned by the remote server. Remote invites are unaffected
because we already check that the event returned from /invite has the
same event ID as the event passed to it.

Add support for the m.replace and m.reference bundled
aggregations.
This should fix plenty of subtle client issues.
Threads are not included in the new code as they have
historically been written to the database. Replacing the
old system would result in issues when switching away from
continuwuity, so saved for later.
Some TODOs have been left re event visibility and ignored users.
These should be OK for now, though.
Also fixes:
- Transaction IDs leaking in event route
- Age not being set for event relations or threads
- Both of the above for search results
Notes down concern with relations table
Paths given via --config at startup are now stored inside the config
struct at runtime, to make it possible to reload config without setting
an env var for the config file location.
This commit refactors the test a bit to run the basic test script with
different configs. Currently we have two configs we test:
- the bare minimum to make it run (base)
- base + default_room_version set to "12"
What's missing? Being able to use separate rooms & lists for typing
indicators.
At the moment, we use the same ones as we use for the timeline, as
todo_rooms is quite intertwined. We need to disentangle this to get that
functionality, although I'm not sure if clients use it.
- Remove most usages of `update_membership` in favor
of directly calling the `mark_as_*` functions
- Store the leave membership event as the value in the
`userroomid_leftstate` table
- Use the `userroomid_leftstate` table to synchronize the
timeline and state for left rooms if possible
We no longer need the tracing patches, so I've removed those and
unpinned them in renovate.
otel's jaeger propagator is deprecated too, so it's replaced with the
builtin W3C TraceContext propagator
- serde-yml has an un-addressed [security issue][sec-issue]
- [saphyr][saphyr] is a pretty recent and active crate that deals with YAML parsing
- based on that, someone recently created [serde-saphyr][serde-saphyr]
---
The change was pretty straightforward and mostly "just a search and replace". The new crate has it's `Error` type split
into serialization and derserialization errors. Hence I created one Continuwuity-Error variant for each instead of just
having a single `Yaml` variant. This was already done previously with the `Toml` errors so I thought this would be
rather acceptable.

- Use systemd's credential system to supply our config file
- Remove `ConfigurationDirectory` to prevent conflicts with package managers
- Set `config_reload_signal` to true using an envvar
Adds two new toggles to the configuration, the first of which allows disabling the policy server checks entirely, and the second of which allows disabling checking events created locally. They're both enabled by default for maximum PS efficacy but allowing them to be disabled allows people who frequently cannot contact policy servers, for example those in censored countries, to be able to still use rooms with pace, allows single-user/trusted-only homeservers to disable the preliminary check on their own events, and also gives an escape hatch in case an issue like #1060 happens again, especially with MSCs not in FCP being moving targets.
In future, I think we should gate all MSC implementations behind config flags, even if they default to on.

I'm not convinced this isn't a rust bug itself,
but CI was complaining about lifetimes
and those complaints couldn't be reproduced locally,
so this should probably fix it maybe?
Build and publish RPM packages for Fedora using rpkg and official
rust-packaging macros. Packages are automatically signed by Forgejo's
built-in package registry (introduced in v9.0).
Publishes packages to organised groups:
- continuwuity (binary): base group (stable/dev/branch-name)
- continuwuity-debuginfo: GROUP-debug
- continuwuity (source RPM): GROUP-src
Workflow triggers on pushes to relevant paths and version tags (v*).
Tagged releases use clean version numbers (v1.2.3 becomes 1.2.3-1)
while branch builds use sanitised branch name versioning.
Uses dnf builddep to install build dependencies directly from the
generated SRPM, ensuring consistency between CI and spec file without
duplication. This also prevents hiding packaging issues that could
occur with --nodeps fallbacks.
Replace single large build cache with separate dependencies and incremental
caches. Dependencies cache survives source code changes and uses tiered
restore keys. Removes build directory from caching to improve CI performance
while maintaining effective compilation caching with sccache.
Replace hashFiles('**/package-lock.json') with node_version since wrangler
is installed via npm without a lockfile to hash. Removes trailing dash from
cache keys and ensures npm dependencies are regenerated when Node.js version
changes.
Replace local detect-runner-os action with external detect-versions@v1 to
reduce custom action maintenance. Add architecture detection for future
cross-platform support and namespace all cache keys with "continuwuity-"
prefix to prevent collisions with other projects on shared runners.
Updates cache mount IDs in Dockerfiles to match the new namespacing
convention, ensuring consistent cache isolation across CI and Docker builds.
This workflow is intended to be ran as dispatch whenever the rocksdb fork changes!
Other than that, it'll run on any toolchain changes (rust-toolchain.toml, Cargo.lock, Cargo.toml) and update the relevant hash accordingly.
**Does not yet work!** Currently, state resolution does not correctly resolve conflicting states. Everything else appears to work as expected, so stateres will be fixed soon, then we should be clear for takeoff.
Also: a lot of things currently accept a nullable room ID that really just don't need to. This will need tidying up before merge. Some authentication checks have also been disabled temporarily but nothing important.
A lot of things are tagged with `TODO(hydra)`, those need resolving before merge. External contributors should PR to the `hydra/public` branch, *not* ` main`.

Runner images have migrated from /usr/share/rust/.cargo/bin to standard
~/.cargo/bin location. Action now checks old location first and migrates
binaries if found, maintaining compatibility with both paths.
Bump cache key to v3 to ensure fresh binary cache after path changes.
Matrix jobs stopped starting after upgrading from runner v9 to v11 due to
changes in job dependency resolution. Remove redundant define-variables job
that computed static image paths and replace with IMAGE_PATH environment
variable.
Also fix timelord action binary caching for compatibility between different
runner images that install cargo binaries in different locations.
Enable automatic merging of ghcr.io/renovatebot/renovate docker image updates
to reduce manual maintenance overhead.
Reorganise package rules by manager type (cargo, github-actions, docker) and
add missing description for cargo concurrency limit rule to improve config
maintainability.
Separate fast release builds from slow max-perf builds to optimise runner
utilisation and provide quicker feedback. Release builds complete first with
standard optimisations, followed by Haswell-optimised dragrace builds once
the safe builds pass successfully.
Extract build logic into focused composite actions for better log visibility
in Forgejo UI. Split monolithic build action into prepare-docker-build,
inline docker build step, and upload-docker-artifacts to ensure each phase
completes independently and shows logs immediately.
Creates separate manifests at each stage to avoid waiting for all builds
before publishing.
The workflow was rebuilding dependencies unnecessarily despite timelord
restoring timestamps because TARGET_CPU and RUST_PROFILE weren't passed
to Docker, creating inconsistent cache keys. Now passes both arguments
for proper cache reuse.
Adds Haswell-optimised builds alongside baseline builds using -march=haswell
for PCLMUL instruction support. Recent build improvements reducing compile
times from 15-20 minutes to ~5 minutes make this additional CPU variant
feasible. Users can pull optimised images with -haswell suffix.
Follow-on to correct #1009. The previous fix downgraded upload-artifact
to v3 but kept download-artifact@v4, creating incompatible storage
formats that prevented artifact pattern filtering from working.
Update all upload-artifact actions to v4 and adjust renovate
configuration to disable automatic updates for forgejo artifact
actions to maintain version consistency.
Resolve upload-artifact v4 GHES compatibility errors by downgrading to v3.
Switch to standard forgejo/download-artifact@v4 for pattern filtering support.
Update renovate configuration to prevent future incompatible upgrades.
Add diagnostic output to digest export step to troubleshoot zero-byte
artifact uploads preventing manifest creation. Include CI triggers for
Element workflow to test changes in pull requests.
* reporting rooms now always returns 200 OK
* reporting an event returns OK if we don't know about the reported event
* removed the score parameter (needs a followup ruwuma update)
Updates the timelord action to fall back to git-warp-time when the cache
is completely empty, enabling timestamp restoration even on fresh builds.
When git-warp-time is used, performs an unshallow fetch to get full history,
while subsequent runs use normal fetches. Simplifies the interface by making
inputs optional with sensible defaults.
Adds binary caching for timelord-cli and git-warp-time tools to avoid
repeated installations, and updates paths to use /usr/share/rust/.cargo/bin/
for the catthehacker runner image used by the dind profile (may need updating
if/when switching to standard image).
The main timelord restore now happens inside the Dockerfile itself, as Docker
intentionally wipes all file mtimes on COPY/ADD operations.
After #992, builds without registry credentials skip Docker image output
but still extract binary artifacts. However, we were still trying to
upload digests for images that weren't created. Add conditional check
to only upload digests when actually pushing to registry.
Fork PRs currently fail binary extraction with 'invalid reference format'
and 'must specify at least one container source' errors. This replaces the
registry-specific docker create/copy method with BuildKit's local output
feature for all builds.
Uses multiple outputs in single build: image export plus local binary
extraction from /sbin. Speeds up extracting binary artifacts and saves a
couple of extra workflow steps in the process.
When BUILDKIT_ENDPOINT is set, builds run on a persistent BuildKit instance,
making runner setup steps unnecessary. Skip Rust toolchain installation,
QEMU setup, caching steps, and timelord to eliminate ~7 operations per job.
Also adds output to git SHA and timestamp steps for visibility.
Cuts at least a minute off average build time through fewer installs,
cache restores, and cache saves.
Docker exporter doesn't support manifest lists (multi-platform builds).
For fork PRs without registry credentials, use 'type=image,push=false'
instead of 'type=docker' to build multi-platform images locally without pushing.
Fork PRs now fail during Docker image build with 'tag is needed when
pushing to registry' because BUILTIN_REGISTRY_ENABLED evaluates to false
without proper credentials, leaving the images list empty. This appears
to be due to recent Forgejo permission changes affecting fork access to
repository secrets.
Add fallback to official registry when credentials unavailable, skip
registry login and push operations for forks, and make merge job
conditional since no digests exist without push. This allows forks to
test Docker builds whilst avoiding authentication failures.
Skip installing Node.js entirely if v20+ is already available, otherwise
install v22. Add npm dependency caching with OS-specific cache keys using
the custom detect-runner-os action for proper cache isolation between
runners. Dependencies normally take just under 10s, so this should more
than halve the doc build time to free up runner slots.
Container failed to start when running as non-root (user 1000:1000) because
copied directories had restrictive 770 permissions, likely due to different
umask in persistent BuildKit. Non-root users couldn't access /usr/lib to
load required dynamic libraries.
Introduces prepper stage using Ubuntu to organize files into layered structure
with explicit 755 directory permissions before copying to scratch image.
Also fixes workflow syntax error and removes docker/** from paths-ignore to
ensure Docker changes trigger CI builds.
Replace mozilla-actions/sccache-action with a custom Forgejo-specific
implementation that eliminates GitHub token dependencies and rate limiting
issues for all contributors regardless of repository permissions.
The new action mirrors sccache binaries to the Forgejo package registry
and queries that instead of GitHub releases, maintaining identical functionality
including hostedtoolcache support.
Consuming this flake is pretty annoying since the rocksdb input is
fetched on every build which takes ~ 10 - 20 sec. By removing it and
replacing it with a `pkgs.fetchFromGitea`, we create an intermediate
derivation which is better for caching reasons.
Allows us to use runners with persistent BuildKit containers for improved
caching and faster build times. Falls back to standard docker-container
driver when BUILDKIT_ENDPOINT environment variable is not set.
systemd creates a dynamic user for
continuwuity and manages directories for
it automatically, so the debian postinst
script no longer needs to do that.
The Fedora RPM packaging files added in PR #950 weren't passing pre-commit
checks, causing CI failures for any branches rebased after that merge. This
applies prek linting fixes (typo correction, trailing whitespace removal,
and EOF newline) to ensure CI passes for all contributors.
The latest Rust nightly compiler (2025-08-27) introduced the
elided-named-lifetimes lint which causes Clippy CI checks to fail
when an elided lifetime ('_) resolves to a named lifetime that's
already in scope.
This commit fixes the Clippy warnings by:
- Making lifetime relationships explicit where 'a is already in scope
- Keeping elided lifetimes ('_) in functions without explicit
lifetime parameters
- Ensuring proper lifetime handling in the database pool module
Affected files (17 total):
- Database map modules: Handle, Key, and KeyVal references in get,
qry, keys, and stream operations
- Database pool module: into_recv_seek function
This change resolves the CI build failures without changing any
functionality, ensuring the codebase remains compatible with the
latest nightly Clippy checks.
Merge rust-checks.yml into prek-checks.yml for a unified workflow that
runs formatting and clippy/test checks in parallel jobs.
Add reusable composite actions:
- setup-rust: Smart Rust toolchain management with caching
* Uses cargo-binstall for pre-built binary downloads
* Integrates Mozilla sccache-action for compilation caching
* Workspace-relative paths for better cache control
* GitHub token support for improved rate limits
- setup-llvm-with-apt: LLVM installation with native dependencies
- detect-runner-os: Consistent OS detection for cache keys
Key improvements:
- Install prek via cargo-binstall --git (crates.io outdated at v0.0.1)
- Download timelord-cli from cargo-quickinstall
- Set BINSTALL_MAXIMUM_RESOLUTION_TIMEOUT=10 to avoid rate limit delays
- Default Rust version 1.87.0 with override support
- Remove redundant sccache stats (handled by Mozilla action)
Significantly reduces CI runtime through binary downloads instead of
compilation while maintaining all existing quality checks.
This is required, since now we're installing `rustfmt` from the latest
state of the fenix repo. This wasn't recent enough for the latest rust
version. The input was locked at (2025-07-02). Now it's up to date.
I verified this by running `rustfmt --version` on my system. Note that I
don't have a system-wide install of rust and only rely on dev shells, so
this can't possibly come from somewhere else.
```
$ rustfmt --version
rustfmt 1.8.0-nightly (6677875279 2025-07-02)
```
This just installs regular rustfmt, which is not needed in this project.
One could say "It doesn't hurt", but in the NixOS dev shell it actually
does since it will shadow nightly rustfmt and we don't have the
`cargo +nightly fmt` synatx on NixOS that is available on other Distros.
Also "It doesn't hurt" to delete it for non NixOS users.
The setup-uv@v6 action has deprecated Node 18 support mid-version by
using the File API, causing workflow failures. Temporarily downgrading
to v5 until we migrate to a better runner image with Node 20+ support.
This works without any further changes. Multiple people in the matrix
room (including myself) have reported that the built executable runs
fine with this. Nevertheless, there might be room for improvements (in
future commits)
- Set platform to 'forgejo' with proper API endpoint
- Use environment variables for all Renovate configuration
- Add git timeout and disable GitHub token warnings
- Move PR limit configuration to workflow
The prefligit project has been renamed to prek due to typosquatting
concerns. This updates our CI to use the new name and recommended
installation method via uv, which significantly reduces setup time
compared to cargo install and includes automatic caching.
- Replace outdated static prefligit action with direct prek invocation
- Use uv as recommended by upstream: https://github.com/j178/prek
- Update check-byte-order-marker to fix-byte-order-marker (deprecated)
- Simplify workflow by removing unused ref calculations
The same .pre-commit-config.yaml works unchanged. Developers can
install locally with 'uvx prek install' or other methods from the repo.
The hardened_malloc feature conflicts with jemalloc, preventing successful
builds with the --features full flag. Commenting out hardened_malloc allows
the full profile to build correctly while maintaining all other features.
Replace unreliable PduCount pagination tokens with ShortEventId throughout
the relations and messages endpoints. ShortEventId provides stable, unique
identifiers that persist across server restarts and database operations.
Key improvements:
- Add token parsing helpers that try ShortEventId first, fall back to
PduCount for backwards compatibility
- Include thread root event when paginating backwards to thread start
- Fix off-by-one error in get_relations that was returning the starting
event in results
- Only return next_batch/prev_batch tokens when more events are available,
preventing clients from making unnecessary requests at thread boundaries
- Ensure consistent token format between /relations, /messages, and /sync
endpoints for interoperability
This fixes duplicate events when scrolling at thread boundaries and ensures
the thread root message is visible when viewing a thread, matching expected
client behaviour.
Ensures access tokens are unique across both user and appservice tables to
prevent authentication ambiguity and potential security issues.
Changes:
- On startup, automatically logout any user devices using tokens that
conflict with appservice tokens (resolves in favour of appservices)
and log a warning with affected user/device details
- When creating new user tokens, check for conflicts with appservice tokens
and generate a new token if a collision would occur
- When registering new appservices, reject registration if the token is
already in use by a user device
- Use futures::select_ok to race token lookups concurrently for better
performance (adapted from tuwunel commit 066097a8)
This fix-forward approach resolves existing token collisions on startup
whilst preventing new ones from being created, without breaking existing
valid authentications.
The find_token optimisation is adapted from tuwunel (matrix-construct/tuwunel)
commit 066097a8: "Optimize user and appservice token queries" by Jason Volk.
Fixes#813: Application services were unable to work because their sender_localpart
user was never created in the database, preventing authentication.
This fix ensures the appservice user account is created when:
- The server starts up and loads existing appservices from the database
- A new appservice is registered via the admin command
Additionally, if an appservice user has been accidentally deactivated, it will be
automatically reactivated when the appservice starts.
The solution centralises all appservice startup logic into a single `start_appservice`
helper method, eliminating code duplication between the registration and startup paths.
Add instructions for proxying .well-known to Continuwuity in with
Traefik. Clarify and expand build instructions in generic deployment,

The first part of getting admin command docs on the website.
There's also the beginnings of manpage generation here, although it's
kinda sus and I'm not sure how it's supposed to work. I'll leave that to
anyone who wants to package it.
We introduce the beginings of the xtask pattern here - we do a lot of
file generation, I thought it would be best to avoid doing that on every
compilation. It also helps avoid lots of runtime deps.
We'll need to document generating this stuff & probably add pre-commit
hooks for it, though.
Adds suggestion to suspend_on_register doc that admins
should add a room that contains information to their
auto_join_rooms as to not confuse new users who may be
lost at the fact they can't join any rooms or send any
messages.
Also moves rustup installation to a seperate workflow and
enables caching.
The sccache action required a github.com api token, so we set
all that up too.
You seem to have replaced `disable_rocksdb_compaction` with `rocksdb_compaction`, since the help is blackmailing me never to set it to `true`, except **true is the default**.
I have tried to make it say what you possibly meant.
This moves all checks related to `forbidden_remote_server_names`,
`forbidden_remote_room_directory_server_names` and
`prevent_media_downloads_from` to a new `moderation` module.
This is useful for implementing more complicated logic globally.
Mostly the changes from #673, but is also relevant for #750
In the previous commit, app services would all appear to be the same
device when accessing the same user. This sets the device ID to be the
appservice ID when available to avoid possible clobbering.
The device ID is not always present when the appservice is the client.
This was causing 500 errors for some users, as appservices can lazy
load from `/messages`.
Fixes#738

When the console is launched, it now prints this message:
conduwuit VERSION admin console
"help" for help, ^D to exit the console, ^\ to stop the server
Although the configuration file was mostly wrapped to a line-width of
80, some lines were wrapped slightly shorter. I fixed this.
In general, all sentences were changed to start with a capital letter
and end with a period or other punctuation mark.
Many of the documentation commets read as, "config option to do XYZ". I
shortened these to simply "do XYZ".
This commit contains two separate fixes:
1) use lowercased github username/repository for the docker
repository name.
This is because image registries only accept
lowercase in image repository names, but github stores the
repository and username in a case-sensitive manner. This broke
image uploads for me, as my username has uppercase chars.
2) change run conditions for some steps.
It will no longer attempt to set up SSH web publishing if the SSH
private key is not set.
It will also run the image registry upload steps if registry
usernames are missing, instead skipping individual uploads where
the token for that registry is missing.
Finally, it simplifies the sccache run conditions to use the
`SCCACHE_GHA_ENABLED` env variable, rather than duplicating that
logic.

- Added support for issuing additional registration tokens, stored in the database, which supplement the existing registration token hardcoded in the config file. These tokens may optionally expire after a certain number of uses or after a certain amount of time has passed. Additionally, the `registration_token_file` configuration option is superseded by this feature and **has been removed**. Use the new `!admin token` command family to manage registration tokens. Contributed by @ginger (#783).
- Implemented a configuration defined admin list independent of the admin room. Contributed by @Terryiscool160. (#1253)
- Added support for invite and join anti-spam via Draupnir and Meowlnir, similar to that of synapse-http-antispam. Contributed by @nex. (#1263)
- Implemented account locking functionality, to complement user suspension. Contributed by @nex. (#1266)
- Added admin command to forcefully log out all of a user's existing sessions. Contributed by @nex. (#1271)
- Implemented toggling the ability for an account to log in without mutating any of its data. Contributed by @nex. (#1272)
- Add support for custom room create event timestamps, to allow generating custom prefixes in hashed room IDs. Contributed by @nex. (#1277)
- Certain potentially dangerous admin commands are now restricted to only be usable in the admin room and server console. Contributed by @ginger.
## Bugfixes
- Fixed unreliable room summary fetching and improved error messages. Contributed by @nex. (#1257)
- Client requested timeout parameter is now applied to e2ee key lookups and claims. Related federation requests are now also concurrent. Contributed by @nex. (#1261)
- Fixed the whoami endpoint returning HTTP 404 instead of HTTP 403, which confused some appservices. Contributed by @nex. (#1276)
## Misc
- The `console` feature is now enabled by default, allowing the server console to be used for running admin commands directly. To automatically open the console on startup, set the `admin_console_automatic` config option to `true`. Contributed by @ginger.
- We now (finally) document our container image mirrors. Contributed by @Jade

and comment on it.
### Linting and Formatting
### Code Style
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.
Please review and follow the [code style guide](/development/code_style.mdx) for formatting, linting, naming conventions, and other code standards.
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
### Running CI tests locally
Continuwuity uses pre-commit hooks to enforce various coding standards and catch common issues before they're committed. These checks include:
conduwuit's CI for tests, linting, formatting, audit, etc use [`engage`][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.
- 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
To test, format, lint, etc that CI would do, install engage, allow the `.envrc` file using `direnv allow`, and run `engage`.
You can run these checks locally by installing [prefligit](https://github.com/j178/prefligit):
All of the tasks are defined at the [engage.toml][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`:
If you would like to run a specific engage task in a specific group, use `just <GROUP> [TASK]`: `engage just lints cargo-fmt`
# Install git hooks to run checks automatically
prefligit install
The following binaries are used in [`engage.toml`][engage.toml]:
# Run all checks
prefligit --all-files
```
- [`engage`][engage]
- `nix`
- [`direnv`][direnv]
- `rustc`
- `cargo`
- `cargo-fmt`
- `rustdoc`
- `cargo-clippy`
- [`cargo-audit`][cargo-audit]
- [`cargo-deb`][cargo-deb]
- [`lychee`][lychee]
- [`markdownlint-cli`][markdownlint-cli]
Alternatively, you can use [pre-commit](https://pre-commit.com/):
```bash
# Requires python
# 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. These must pass before the PR is merged.
### Running tests locally
Tests, compilation, and linting can be run with standard Cargo commands:
```bash
# Run tests
cargo test
# Check compilation
cargo check --workspace --features full
# Run lints
cargo clippy --workspace --features full
# Auto-fix: cargo clippy --workspace --features full --fix --allow-staged;
# Format code (must use nightly)
cargo +nightly fmt
```
### Matrix tests
CI runs [Complement][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.
Continuwuity uses [Complement][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 you'd like to run Complement locally using Nix, see the [testing](docs/development/testing.md) page.
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][sytest] support will come soon.
[Sytest][sytest] is currently unsupported.
### Writing documentation
conduwuit's website uses [`mdbook`][mdbook] and deployed via CI using GitHub Pages in the [`documentation.yml`][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.
Continuwuity's website uses [`mdbook`][mdbook] and is deployed via CI using Cloudflare Pages
in the [`documentation.yml`][documentation.yml] workflow file. All documentation is in the `docs/`
directory at the top level.
To build the documentation using Nix, run: `bin/nix-build-and-cache just .#book`
To build the documentation locally:
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.
1. Install mdbook if you don't have it already:
```bash
cargo install mdbook # or cargo binstall, or another method
```
### Inclusivity and Diversity
2. Build the documentation:
```bash
mdbook build
```
All **MUST** code and write with inclusivity and diversity in mind. See the [following page by Google on writing inclusive code and documentation](https://developers.google.com/style/inclusive-documentation).
The output of the mdbook generation is in `public/`. You can open the HTML files directly in your browser without needing a web server.
This **EXPLICITLY** forbids usage of terms like "blacklist"/"whitelist" and "master"/"slave", [forbids gender-specific words and phrases](https://developers.google.com/style/pronouns#gender-neutral-pronouns), 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](https://developers.google.com/style/inclusive-documentation#write-around).
### Commit Messages
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. 🏳️⚧️
Continuwuity follows the [Conventional Commits](https://www.conventionalcommits.org/) specification for commit messages. This provides a standardized format that makes the commit history more readable and enables automated tools to generate changelogs.
### Variable, comment, function, etc standards
The basic structure is:
Rust's default style and standards with regards to [function names, variable names, comments](https://rust-lang.github.io/api-guidelines/naming.html), etc applies here.
```
<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 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.

# continuwuity
<!-- ANCHOR: catchphrase -->
### a very cool, featureful fork of [Conduit](https://conduit.rs/)
## A community-driven [Matrix](https://matrix.org/) homeserver in Rust
[](https://matrix.to/#/#continuwuity:continuwuity.org?via=continuwuity.org&via=ellis.link&via=explodie.org&via=matrix.org) [](https://matrix.to/#/#space:continuwuity.org?via=continuwuity.org&via=ellis.link&via=explodie.org&via=matrix.org)
<!-- ANCHOR_END: catchphrase -->
Visit the [Conduwuit documentation](https://conduwuit.puppyirl.gay/) for more information.
[continuwuity] is a Matrix homeserver written in Rust.
It's the official community continuation of the [conduwuit](https://github.com/girlbossceo/conduwuit) homeserver.
<!-- ANCHOR: body -->
#### What is Matrix?
[Matrix](https://matrix.org) 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.
An official conduwuit server ran by me is available at transfem.dev ([element.transfem.dev](https://element.transfem.dev) / [cinny.transfem.dev](https://cinny.transfem.dev))
### Why does this exist?
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](https://transfem.dev/homeserver_rules.txt)
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.
transfem.dev is also listed at [servers.joinmatrix.org](https://servers.joinmatrix.org/)
We aim to provide a stable, well-maintained alternative for current conduwuit users and welcome newcomers seeking a lightweight, efficient Matrix homeserver.
#### What is the current status?
### Who are we?
conduwuit is a hard fork of Conduit which is in beta, meaning you can join and participate in most
Matrix rooms, but not all features are supported and you might run into bugs
from time to time.
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](https://matrix.org) 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](https://continuwuity.org) 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](https://forgejo.ellis.link/continuwuation/continuwuity/issues).
- [Packaging & availability in more places](https://forgejo.ellis.link/continuwuation/continuwuity/issues/747)
We haven't written up a guide on migrating from incompatible homeservers yet. Reach out to us if you need to do this!
<!-- ANCHOR_END: body -->
## Contribution
### Development flow
- Features / changes must developed in a separate branch
- For each change, create a descriptive PR
- Your code will be reviewed by one or more of the continuwuity developers
- The branch will be deployed live on multiple tester's matrix servers to shake out bugs
- Once all testers and reviewers have agreed, the PR will be merged to the main branch
- The main branch will have nightly builds deployed to users on the cutting edge
- Every week or two, a new release is cut.
The main branch is always green!
### Policy on pulling from other forks
We welcome contributions from other forks of conduwuit, subject to our review process.
When incorporating code from other forks:
- All external contributions must go through our standard PR process
- Code must meet our quality standards and pass tests
- Code changes will require testing on multiple test servers before merging
- Attribution will be given to original authors and forks
- We prioritize stability and compatibility when evaluating external contributions
- Features that align with our project goals will be given priority consideration

This document outlines the security policy for Continuwuity. Our goal is to maintain a secure platform for all users, and we take security matters seriously.
## Supported Versions
We provide security updates for the following versions of Continuwuity:
| Version | Supported |
| -------------- |:----------------:|
| Latest release | ✅ |
| Main branch | ✅ |
| Older releases | ❌ |
We may backport fixes to the previous release at our discretion, but we don't guarantee this.
## Reporting a Vulnerability
### Responsible Disclosure
We appreciate the efforts of security researchers and the community in identifying and reporting vulnerabilities. To ensure that potential vulnerabilities are addressed properly, please follow these guidelines:
1. **Contact members of the team directly** over E2EE private message.
2. **Email the security team** at [security@continuwuity.org](mailto:security@continuwuity.org). This is not E2EE, so don't include sensitive details.
3. **Do not disclose the vulnerability publicly** until it has been addressed
4. **Provide detailed information** about the vulnerability, including:
- A clear description of the issue
- Steps to reproduce
- Potential impact
- Any possible mitigations
- Version(s) affected, including specific commits if possible
If you have any doubts about a potential security vulnerability, contact us via private channels first! We'd prefer that you bother us, instead of having a vulnerability disclosed without a fix.
### What to Expect
When you report a security vulnerability:
1. **Acknowledgment**: We will acknowledge receipt of your report.
2. **Assessment**: We will assess the vulnerability and determine its impact on our users
3. **Updates**: We will provide updates on our progress in addressing the vulnerability, and may request you help test mitigations
4. **Resolution**: Once resolved, we will notify you and discuss coordinated disclosure
5. **Credit**: We will recognize your contribution (unless you prefer to remain anonymous)
## Security Update Process
When security vulnerabilities are identified:
1. We will develop and test fixes in a private fork
2. Security updates will be released as soon as possible
3. Release notes will include information about the vulnerabilities, avoiding details that could facilitate exploitation where possible
4. Critical security updates may be backported to the previous stable release

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](../deploying/generic.md) for further information if needed as usage of the Debian package is generally related.
### Configuration
When installed, the example config is placed at `/etc/conduwuit/conduwuit.toml` as the default config. At the minimum, you will need to change your `server_name` here.
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`](../configuration/examples.md#example-systemd-unit-file) 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](../deploying/generic.md#setting-up-the-reverse-proxy) as it's the easiest and most user friendly.
If you run into any problems while setting up an Appservice: ask us in [#conduwuit:puppygock.gay](https://matrix.to/#/#conduwuit:puppygock.gay) or [open an issue on GitHub](https://github.com/girlbossceo/conduwuit/issues/new).

[open an issue on Forgejo](https://forgejo.ellis.link/continuwuation/continuwuity/issues/new).
## 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.

[Continuwuity Matrix Space](https://matrix.to/#/#space:continuwuity.org?via=continuwuity.org&via=ellis.link&via=explodie.org&via=matrix.org) and its rooms, including:
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.
Continuwuity is available in the `archlinuxcn` repository and AUR with the same package name `continuwuity`, which includes the latest tagged 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 and start the continuwuity.service.

When you have the image you can simply run it with
```bash
docker run -d -p 8448:6167 \
-v db:/var/lib/conduwuit/ \
-e CONDUWUIT_SERVER_NAME="your.server.name" \
-e CONDUWUIT_DATABASE_BACKEND="rocksdb" \
-e CONDUWUIT_ALLOW_REGISTRATION=false \
--name conduit <link>
```
or you can use [docker compose](#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](../configuration/examples.md).
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`](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`](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`](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`](docker-compose.with-caddy.yml) and replace all `example.com` placeholders with your own domain
- For any other reverse proxy, use [`docker-compose.yml`](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:
```bash
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](generic.md).
### Build
To build the conduwuit image with docker-compose, you first need to open and modify the `docker-compose.yml` file. There you need to comment the `image:` option and uncomment the `build:` option. Then call docker compose with:
```bash
docker compose up
```
This will also start the container right afterwards, so if want it to run in detached mode, you also should use the `-d` flag.
### 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:
```bash
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,
Replace all `example.com` placeholders with your own domain.
```yaml file="./docker-compose.with-caddy.yml"
```
</details>
### For other reverse proxies
<details>
<summary>docker-compose.yml</summary>
```yaml file="./docker-compose.yml"
```
</details>
### Override file
<details>
<summary>docker-compose.override.yml</summary>
```yaml file="./docker-compose.override.yml"
```
</details>
When picking the Traefik-related compose file, rename it to
`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:
```bash
docker network create caddy
```
After that, you can rename it to `docker-compose.yml` and spin up the
containers!
Additional info about deploying Continuwuity can be found [here](generic.mdx).
### Build
Official Continuwuity images are built using **Docker Buildx** and the Dockerfile found at [`docker/Dockerfile`][dockerfile-path]. This approach uses common Docker tooling and enables efficient multi-platform builds.
The resulting images are widely 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.

```dockerfile file="../../docker/Dockerfile"
```
</details>
To build an image locally using Docker Buildx, you can typically run a command like:
```bash
# Build for the current platform and load into the local Docker daemon
If you have already built the image or want to use one from the registries, you
can start the container and everything else in the compose file in detached
mode with:
```bash
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 an easy-to-use
reverse proxy for making containerized apps and services available through the
web. With the Traefik-related docker-compose files provided above, it is equally easy
to deploy and use Continuwuity, with a small caveat. If you have already looked at
the files, you should have seen the `well-known` service, which is the
small caveat. Traefik is simply a proxy and load balancer and cannot
serve any kind of content. 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 serves
those two files.
Alternatively, you can use Continuwuity's built-in delegation file capability. Set up the delegation files in the configuration file, and then proxy paths under `/.well-known/matrix` to continuwuity. For example, the label ``traefik.http.routers.continuwuity.rule=(Host(`matrix.ellis.link`) || (Host(`ellis.link`) && PathPrefix(`/.well-known/matrix`)))`` does this for the domain `ellis.link`.
Continuwuity currently does not provide FreeBSD builds or FreeBSD packaging. However, Continuwuity does build and work on FreeBSD using the system-provided RocksDB.
Contributions to get Continuwuity packaged for FreeBSD are welcome.
> If you run into any problems while setting up conduwuit, ask us
> in `#conduwuit:puppygock.gay` or [open an issue on GitHub](https://github.com/girlbossceo/conduwuit/issues/new).
## Installing conduwuit
You may simply download the binary that fits your machine. Run `uname -m` to see what you need.
Prebuilt binaries can be downloaded from the latest tagged release [here](https://github.com/girlbossceo/conduwuit/releases/latest).
The latest tagged release also includes the Debian packages.
Alternatively, you may compile the binary yourself. We recommend using [Lix](https://lix.systems) to build conduwuit as this has the most guaranteed
reproducibiltiy and easiest to get a build environment and output going.
Otherwise, follow standard Rust project build guides (installing git and cloning the repo, getting the Rust toolchain via rustup, installing LLVM toolchain + libclang, installing liburing for io_uring and RocksDB, etc).
## 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 or Fedora/RHEL, you can use this command to create a conduwuit user:
conduwuit uses the ports 443 and 8448 both of which need to be open in the firewall.
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.
## Setting up a systemd service
The systemd unit for conduwuit can be found [here](../configuration/examples.md#example-systemd-unit-file). You may need to change the `ExecStart=` path to where you placed the conduwuit binary.
## 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](../configuration/examples.md).**Please take a moment to read it. 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:
```bash
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:
Refer to the documentation or various guides online of your chosen reverse proxy software. A [Caddy](https://caddyserver.com/) 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 using Apache, you need to use `nocanon` to prevent this.
### Caddy
Create `/etc/caddy/conf.d/conduwuit_caddyfile` and enter this (substitute for your server name).
```caddy
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.
```bash
sudo systemctl enable --now caddy
```
## You're done
Now you can start conduwuit with:
```bash
sudo systemctl start conduwuit
```
Set it to start automatically when your system boots with:
```bash
sudo systemctl enable conduwuit
```
## How do I know it works?
You can open [a Matrix client](https://matrix.org/ecosystem/clients), enter your homeserver and try to register.
You can also use these commands as a quick health check (replace `your.server.name`).
and, for amd64, target the haswell CPU architecture.
### Compiling
Alternatively, you may compile the binary yourself.
### Building with the Rust toolchain
If wanting to build using standard Rust toolchains, make sure you install:
- (On linux) `liburing-dev` on the compiling machine, and `liburing` on the target host
- (On linux) `pkg-config` on the compiling machine to allow finding `liburing`
- A C++ compiler and (on linux) `libclang` for RocksDB
You can build Continuwuity using `cargo build --release`.
### Building with Nix
If you prefer, you can use Nix (or [Lix](https://lix.systems)) to build Continuwuity. This provides improved reproducibility and makes it easy to set up a build environment and generate output. This approach also allows for 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.
## Adding a Continuwuity user
While Continuwuity can run as any user, it is better to use dedicated users for
different services. This also ensures that the file permissions
are set up correctly.
In Debian, you can use this command to create a Continuwuity user:
We recommend Caddy as a reverse proxy because it is trivial to use and handles 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 the following (substitute your actual 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.
```bash
sudo systemctl enable --now caddy
```
### Other Reverse Proxies
As we prefer our users to use Caddy, we do not provide configuration files for other proxies.
You will need to reverse proxy everything under the following routes:
- `/_matrix/` - core Matrix C-S and S-S APIs
- `/_conduwuit/` and/or `/_continuwuity/` - 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:
For Apache and Nginx there are many examples available online.
Lighttpd is not supported as it appears to interfere with the `X-Matrix` Authorization
header, making federation non-functional. If you find a workaround, please share it so we can add it to this documentation.
If using Apache, you need to use `nocanon` in your `ProxyPass` directive to prevent httpd from interfering with the `X-Matrix` header (note that Apache is not ideal as a general reverse proxy, so we discourage using it if alternatives are available).
If using Nginx, you need to pass the request URI to Continuwuity using `$request_uri`, like this:
- `proxy_pass http://127.0.0.1:6167$request_uri;`
- `proxy_pass http://127.0.0.1:6167;`
Nginx users need to increase the `client_max_body_size` setting (default is 1M) to match the
`max_request_size` defined in conduwuit.toml.
## You're done
Now you can start Continuwuity with:
```bash
sudo systemctl start conduwuit
```
Set it to start automatically when your system boots with:
```bash
sudo systemctl enable conduwuit
```
## How do I know it works?
You can open [a Matrix client](https://matrix.org/ecosystem/clients), enter your
homeserver address, and try to register.
You can also use these commands as a quick health check (replace
NixOS packages Continuwuity as `matrix-continuwuity`. This package includes both the Continuwuity software and a dedicated NixOS module for configuration and deployment.
## Installation methods
You can acquire Continuwuity with Nix (or [Lix][lix]) from these sources:
* Directly from Nixpkgs using the official package (`pkgs.matrix-continuwuity`)
* The `flake.nix` at the root of the Continuwuity repo
* The `default.nix` at the root of the Continuwuity repo
## NixOS module
Continuwuity now has an official NixOS module that simplifies configuration and deployment. The module is available in Nixpkgs as `services.matrix-continuwuity` from NixOS 25.05.
Here's a basic example of how to use the module:
```nix
{ config, pkgs, ... }:
{
services.matrix-continuwuity = {
enable = true;
settings = {
global = {
server_name = "example.com";
# Listening on localhost by default
# address and port are handled automatically
allow_registration = false;
allow_encryption = true;
allow_federation = true;
trusted_servers = [ "matrix.org" ];
};
};
};
}
```
### Available options
The NixOS module provides these configuration options:
- `enable`: Enable the Continuwuity service
- `user`: The user to run Continuwuity as (defaults to "continuwuity")
- `group`: The group to run Continuwuity as (defaults to "continuwuity")
- `extraEnvironment`: Extra environment variables to pass to the Continuwuity server
- `package`: The Continuwuity package to use
- `settings`: The Continuwuity configuration (in TOML format)
Use the `settings` option to configure Continuwuity itself. See the [example configuration file](../reference/config.mdx) for all available options.
### UNIX sockets
The NixOS module natively supports UNIX sockets through the `global.unix_socket_path` option. When using UNIX sockets, set `global.address` to `null`:
```nix
services.matrix-continuwuity = {
enable = true;
settings = {
global = {
server_name = "example.com";
address = null; # Must be null when using unix_socket_path
unix_socket_perms = 660; # Default permissions for the socket
# ...
};
};
};
```
The module automatically sets the correct `RestrictAddressFamilies` in the systemd service configuration to allow access to UNIX sockets.
### RocksDB database
Continuwuity exclusively uses RocksDB as its database backend. The system configures the database path automatically to `/var/lib/continuwuity/` and you cannot change it due to the service's reliance on systemd's StateDir.
If you're migrating from Conduit with SQLite, use this [tool to migrate a Conduit SQLite database to RocksDB](https://github.com/ShadowJonathan/conduit_toolbox/).
### jemalloc and hardened profile
Continuwuity uses jemalloc by default. This may interfere with the [`hardened.nix` profile][hardened.nix] because it uses `scudo` by default. Either disable/hide `scudo` from Continuwuity or disable jemalloc like this:
```nix
services.matrix-continuwuity = {
enable = true;
package = pkgs.matrix-continuwuity.override {
enableJemalloc = false;
};
# ...
};
```
## Upgrading from Conduit
If you previously used Conduit with the `services.matrix-conduit` module:
1. Ensure your Conduit uses the RocksDB backend, or migrate from SQLite using the [migration tool](https://github.com/ShadowJonathan/conduit_toolbox/)
2. Switch to the new module by changing `services.matrix-conduit` to `services.matrix-continuwuity` in your configuration
3. Update any custom configuration to match the new module's structure
## Reverse proxy configuration
You'll need to set up a reverse proxy (like nginx or caddy) to expose Continuwuity to the internet. Configure your reverse proxy to forward requests to `/_matrix` on port 443 and 8448 to your Continuwuity instance.
This guide outlines the coding standards and best practices for Continuwuity development. These guidelines help avoid bugs and maintain code consistency, readability, and quality across the project.
These guidelines apply to new code on a best-effort basis. When modifying existing code, follow existing patterns in the immediate area you're changing and then gradually improve code style when making substantial changes.
## General Principles
- **Clarity over cleverness**: Write code that is easy to understand and maintain
- **Consistency**: Pragmatically follow existing patterns in the codebase, rather than adding new dependencies.
- **Safety**: Prefer safe, explicit code over unsafe code with implicit requirements
- **Performance**: Consider performance implications, but not at the expense of correctness or maintainability
## Formatting and Linting
All code must satisfy lints (clippy, rustc, rustdoc, etc) and be formatted using **nightly** rustfmt (`cargo +nightly fmt`). Many of the `rustfmt.toml` features depend on the nightly toolchain.
If you need to allow a lint, ensure it's either obvious why (e.g. clippy saying redundant clone but it's actually required) or add a comment explaining the reason. Do not write inefficient code just to satisfy lints. If a lint is wrong and provides a less efficient solution, allow the lint and mention that in a comment.
If making large formatting changes across unrelated files, create a separate commit so it can be added to the `.git-blame-ignore-revs` file.
## Rust-Specific Guidelines
### Naming Conventions
Follow standard Rust naming conventions as outlined in the [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/naming.html):
- Use `snake_case` for functions, variables, and modules
- Use `PascalCase` for types, traits, and enum variants
- Use `SCREAMING_SNAKE_CASE` for constants and statics
- Use descriptive names that clearly indicate purpose
// Retry with exponential backoff because federation can be flaky
// due to network issues or temporary server overload
let mut retry_delay = Duration::from_millis(100);
for attempt in 1..=MAX_RETRIES {
match try_send_request(destination, &request).await {
Ok(response) => return Ok(response),
Err(err) if err.is_retriable() && attempt < MAX_RETRIES => {
warn!(
destination = %destination,
attempt = attempt,
error = ?err,
retry_delay_ms = retry_delay.as_millis(),
"Federation request failed, retrying"
);
tokio::time::sleep(retry_delay).await;
retry_delay *= 2; // Exponential backoff
}
Err(err) => return Err(err),
}
}
unreachable!("Loop should have returned or failed by now")
}
```
### Async Patterns
- Use `async`/`await` appropriately
- Avoid blocking operations in async contexts
- Consider using `tokio::task::spawn_blocking` for CPU-intensive work
```rs
// Good - non-blocking async operation
pub async fn fetch_user_profile(
&self,
user_id: &UserId,
) -> Result<UserProfile, Error> {
let profile = self.db
.get_user_profile(user_id)
.await?;
Ok(profile)
}
// Good - CPU-intensive work moved to blocking thread
pub async fn generate_thumbnail(
&self,
image_data: Vec<u8>,
) -> Result<Vec<u8>, Error> {
tokio::task::spawn_blocking(move || {
image::generate_thumbnail(image_data)
})
.await
.map_err(|_| Error::TaskJoinError)?
}
```
## Inclusivity and Diversity Guidelines
All code and documentation must be written with inclusivity and diversity in mind. This ensures our software is welcoming and accessible to all users and contributors. Follow the [Google guide on writing inclusive code and documentation](https://developers.google.com/style/inclusive-documentation) for comprehensive guidance.
The following types of language are explicitly forbidden in all code, comments, documentation, and commit messages:
**Ableist language:** Avoid terms like "sanity check", "crazy", "insane", "cripple", or "blind to". Use alternatives like "validation", "unexpected", "disable", or "unaware of".
**Socially-charged technical terms:** Replace overly divisive terminology with neutral alternatives:
- "whitelist/blacklist" → "allowlist/denylist" or "permitted/blocked"
- "master/slave" → "primary/replica", "controller/worker", or "parent/child"
When working with external dependencies that use non-inclusive terminology, avoid propagating them in your own APIs and variable names.
Use diverse examples in documentation that avoid culturally-specific references, assumptions about user demographics, or unnecessarily gendered language. Design with accessibility and inclusivity in mind by providing clear error messages and considering diverse user needs.
This software is intended to be used by everyone regardless of background, identity, or ability. Write code and documentation that reflects this commitment to inclusivity.
Alternatively, you can use [pre-commit](https://pre-commit.com/):
```bash
# Requires python
# 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. These must pass before the PR is merged.
### Running tests locally
Tests, compilation, and linting can be run with standard Cargo commands:
```bash
# Run tests
cargo test
# Check compilation
cargo check --workspace --features full
# Run lints
cargo clippy --workspace --features full
# Auto-fix: cargo clippy --workspace --features full --fix --allow-staged;
# Format code (must use nightly)
cargo +nightly fmt
```
### Matrix tests
Continuwuity uses [Complement][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][sytest] is currently unsupported.
### Writing documentation
Continuwuity's website uses [`mdbook`][mdbook] and is deployed via CI using Cloudflare Pages
in the [`documentation.yml`][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:
```bash
cargo install mdbook # or cargo binstall, or another method
```
2. Build the documentation:
```bash
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.
### Commit Messages
Continuwuity follows the [Conventional Commits](https://www.conventionalcommits.org/) 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.). Run pre-commit for this.
2. Your code follows the [code style guide](./code_style)
3. Your commit messages follow the conventional commits format
4. Tests are added for new functionality
5. Documentation is updated if needed
6. You have written a [news fragment](#writing-news-fragments) for your changes
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.
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`][2]. macOS does not fully support our usage of `RTLD_GLOBAL` possibly due to some thread-local issues. [This Rust issue][3] may be of relevance, specifically [this comment][4]. 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][7] 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][7] 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][5], 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][7] 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][6] 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][8] 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][6]) 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.
