# Dendrite [](https://buildkite.com/matrix-dot-org/dendrite) [](https://matrix.to/#/#dendrite-dev:matrix.org) [](https://matrix.to/#/#dendrite:matrix.org)
|
|
|
|
Dendrite is a second-generation Matrix homeserver written in Go. It is not recommended to use Dendrite as
|
|
a production homeserver at this time as there is no stable release.
|
|
|
|
Dendrite will start to receive versioned releases stable enough to run [once we enter beta](https://github.com/matrix-org/dendrite/milestone/8).
|
|
|
|
# Quick start
|
|
|
|
Requires Go 1.13+ and SQLite3 (Postgres is also supported):
|
|
|
|
```bash
|
|
$ git clone https://github.com/matrix-org/dendrite
|
|
$ cd dendrite
|
|
|
|
# generate self-signed certificate and an event signing key for federation
|
|
$ go build ./cmd/generate-keys
|
|
$ ./generate-keys --private-key matrix_key.pem --tls-cert server.crt --tls-key server.key
|
|
|
|
# Copy and modify the config file:
|
|
# you'll need to set a server name and paths to the keys at the very least, along with setting
|
|
# up the database filenames
|
|
$ cp dendrite-config.yaml dendrite.yaml
|
|
|
|
# build and run the server
|
|
$ go build ./cmd/dendrite-monolith-server
|
|
$ ./dendrite-monolith-server --tls-cert server.crt --tls-key server.key --config dendrite.yaml
|
|
```
|
|
|
|
Then point your favourite Matrix client at `http://localhost:8008`. For full installation information, see
|
|
[INSTALL.md](docs/INSTALL.md). For running in Docker, see [build/docker](build/docker).
|
|
|
|
# Progress
|
|
|
|
We use a script called Are We Synapse Yet which checks Sytest compliance rates. Sytest is a black-box homeserver
|
|
test rig with around 900 tests. The script works out how many of these tests are passing on Dendrite and it
|
|
updates with CI. As of August 2020 we're at around 52% CS API coverage and 65% Federation coverage, though check
|
|
CI for the latest numbers. In practice, this means you can communicate locally and via federation with Synapse
|
|
servers such as matrix.org reasonably well. There's a long list of features that are not implemented, notably:
|
|
- Receipts
|
|
- Push
|
|
- Search and Context
|
|
- User Directory
|
|
- Presence
|
|
- Guests
|
|
|
|
We are prioritising features that will benefit single-user homeservers first (e.g Receipts, E2E) rather
|
|
than features that massive deployments may be interested in (User Directory, OpenID, Guests, Admin APIs, AS API).
|
|
This means Dendrite supports amongst others:
|
|
- Core room functionality (creating rooms, invites, auth rules)
|
|
- Federation in rooms v1-v6
|
|
- Backfilling locally and via federation
|
|
- Accounts, Profiles and Devices
|
|
- Published room lists
|
|
- Typing
|
|
- Media APIs
|
|
- Redaction
|
|
- Tagging
|
|
- E2E keys and device lists
|
|

# Contributing
|
|
|
|
We would be grateful for any help on issues marked as
|
|
[Are We Synapse Yet](https://github.com/matrix-org/dendrite/labels/are-we-synapse-yet). These issues
|
|
all have related Sytests which need to pass in order for the issue to be closed. Once you've written your
|
|
code, you can quickly run Sytest to ensure that the test names are now passing.
|
|
|
|
For example, if the test `Local device key changes get to remote servers` was marked as failing, find the
|
|
test file (e.g via `grep` or via the
|
|
[CI log output](https://buildkite.com/matrix-dot-org/dendrite/builds/2826#39cff5de-e032-4ad0-ad26-f819e6919c42)
|
|
it's `tests/50federation/40devicelists.pl` ) then to run Sytest:
|
|
```
|
|
docker run --rm --name sytest
|
|
-v "/Users/kegan/github/sytest:/sytest"
|
|
-v "/Users/kegan/github/dendrite:/src"
|
|
-v "/Users/kegan/logs:/logs"
|
|
-v "/Users/kegan/go/:/gopath"
|
|
-e "POSTGRES=1" -e "DENDRITE_TRACE_HTTP=1"
|
|
matrixdotorg/sytest-dendrite:latest tests/50federation/40devicelists.pl
|
|
```
|
|
See [sytest.md](docs/sytest.md) for the full description of these flags.
|
|
|
|
You can try running sytest outside of docker for faster runs, but the dependencies can be temperamental
|
|
and we recommend using docker where possible.
|
|
```
|
|
cd sytest
|
|
export PERL5LIB=$HOME/lib/perl5
|
|
export PERL_MB_OPT=--install_base=$HOME
|
|
export PERL_MM_OPT=INSTALL_BASE=$HOME
|
|
./install-deps.pl
|
|
|
|
./run-tests.pl -I Dendrite::Monolith -d $PATH_TO_DENDRITE_BINARIES
|
|
```
|
|
|
|
Sometimes Sytest is testing the wrong thing or is flakey, so it will need to be patched.
|
|
Ask on `#dendrite-dev:matrix.org` if you think this is the case for you and we'll be happy to help.

|
|
look for [Good First Issues](https://github.com/matrix-org/dendrite/labels/good%20first%20issue). If you're

# Hardware requirements
|
|
|
|
Dendrite in Monolith + SQLite works in a range of environments including iOS and in-browser via WASM.
|
|
|
|
For small homeserver installations joined on ~10s rooms on matrix.org with ~100s of users in those rooms, including some
|
|
encrypted rooms:
|
|
- Memory: uses around 100MB of RAM, with peaks at around 200MB.
|
|
- Disk space: After a few months of usage, the database grew to around 2GB (in Monolith mode).
|
|
- CPU: Brief spikes when processing events, typically idles at 1% CPU.
|
|
|
|
This means Dendrite should comfortably work on things like Raspberry Pis.

# Discussion
|
|
|
|
For questions about Dendrite we have a dedicated room on Matrix
|
|
[#dendrite:matrix.org](https://matrix.to/#/#dendrite:matrix.org). Development
|
|
discussion should happen in
|
|
[#dendrite-dev:matrix.org](https://matrix.to/#/#dendrite-dev:matrix.org).
