Dendrite is a second-generation Matrix homeserver written in Go. It is not recommended to use Dendrite as
2020-08-25 07:11:41 +00:00
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
2020-08-12 09:50:52 +00:00
updates with CI. As of August 2020 we're at around 52% CS API coverage and 65% Federation coverage, though check
2020-07-14 11:58:00 +00:00
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
2020-08-12 09:50:52 +00:00
- E2E keys and device lists

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.
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.
If you're new to the project, see [CONTRIBUTING.md ](docs/CONTRIBUTING.md ) to get up to speed then
look for [Good First Issues ](https://github.com/matrix-org/dendrite/labels/good%20first%20issue ). If you're
familiar with the project, look for [Help Wanted ](https://github.com/matrix-org/dendrite/labels/help-wanted )
