Support for m.login.token (#2014)
* Add GOPATH to PATH in find-lint.sh.

The user doesn't necessarily have it in PATH.

* Refactor LoginTypePassword and Type to support m.login.token and m.login.sso.

For login token:

* m.login.token will require deleting the token after completeAuth has
  generated an access token, so a cleanup function is returned by
  Type.Login.
* Allowing different login types will require parsing the /login body
  twice: first to extract the "type" and then the type-specific parsing.
  Thus, we will have to buffer the request JSON in /login, like
  UserInteractive already does.

For SSO:

* NewUserInteractive will have to also use GetAccountByLocalpart. It
  makes more sense to just pass a (narrowed-down) accountDB interface
  to it than adding more function pointers.

Code quality:

* Passing around (and down-casting) interface{} for login request types
  has drawbacks in terms of type-safety, and no inherent benefits. We
  always decode JSON anyway. Hence renaming to Type.LoginFromJSON. Code
  that directly uses LoginTypePassword with parsed data can still use
  Login.
* Removed a TODO for SSO. This is already tracked in #1297.
* httputil.UnmarshalJSON is useful because it returns a JSONResponse.

This change is intended to have no functional changes.

* Support login tokens in User API.

This adds full lifecycle functions for login tokens: create, query, delete.

* Support m.login.token in /login.

* Fixes for PR review.

* Set @matrix-org/dendrite-core as repository code owner

* Return event NID from `StoreEvent`, match PSQL vs SQLite behaviour, tweak backfill persistence (#2071)

Dendrite Build Status Dendrite Dendrite Dev

Dendrite is a second-generation Matrix homeserver written in Go. It intends to provide an efficient, reliable and scalable alternative to Synapse:

  • Efficient: A small memory footprint with better baseline performance than an out-of-the-box Synapse.
  • Reliable: Implements the Matrix specification as written, using the same test suite as Synapse as well as a brand new Go test suite.
  • Scalable: can run on multiple machines and eventually scale to massive homeserver deployments.

As of October 2020, Dendrite has now entered beta which means:

  • Dendrite is ready for early adopters. We recommend running in Monolith mode with a PostgreSQL database.
  • Dendrite has periodic semver releases. We intend to release new versions as we land significant features.
  • Dendrite supports database schema upgrades between releases. This means you should never lose your messages when upgrading Dendrite.
  • Breaking changes will not occur on minor releases. This means you can safely upgrade Dendrite without modifying your database or config file.

This does not mean:

  • Dendrite is bug-free. It has not yet been battle-tested in the real world and so will be error prone initially.
  • All of the CS/Federation APIs are implemented. We are tracking progress via a script called 'Are We Synapse Yet?'. In particular, presence and push notifications are entirely missing from Dendrite. See CHANGES.md for updates.
  • Dendrite is ready for massive homeserver deployments. You cannot shard each microservice, only run each one on a different machine.

Currently, we expect Dendrite to function well for small (10s/100s of users) homeserver deployments as well as P2P Matrix nodes in-browser or on mobile devices. In the future, we will be able to scale up to gigantic servers (equivalent to matrix.org) via polylith mode.

If you have further questions, please take a look at our FAQ or join us in:

Requirements

To build Dendrite, you will need Go 1.16 or later.

For a usable federating Dendrite deployment, you will also need:

  • A domain name (or subdomain)
  • A valid TLS certificate issued by a trusted authority for that domain
  • SRV records or a well-known file pointing to your deployment

Also recommended are:

  • A PostgreSQL database engine, which will perform better than SQLite with many users and/or larger rooms
  • A reverse proxy server, such as nginx, configured like this sample

The Federation Tester can be used to verify your deployment.

Get started

If you wish to build a fully-federating Dendrite instance, see INSTALL.md. For running in Docker, see build/docker.

The following instructions are enough to get Dendrite started as a non-federating test deployment using self-signed certificates and SQLite databases:

$ git clone https://github.com/matrix-org/dendrite
$ cd dendrite
$ ./build.sh

# Generate a Matrix signing key for federation (required)
$ ./bin/generate-keys --private-key matrix_key.pem

# Generate a self-signed certificate (optional, but a valid TLS certificate is normally
# needed for Matrix federation/clients to work properly!)
$ ./bin/generate-keys --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 connection strings.
$ cp dendrite-config.yaml dendrite.yaml

# Build and run the server:
$ ./bin/dendrite-monolith-server --tls-cert server.crt --tls-key server.key --config dendrite.yaml

Then point your favourite Matrix client at http://localhost:8008 or https://localhost:8448.

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 January 2022 we're at around 65% CS API coverage and 92% 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:

  • 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-v7
  • Backfilling locally and via federation
  • Accounts, Profiles and Devices
  • Published room lists
  • Typing
  • Media APIs
  • Redaction
  • Tagging
  • E2E keys and device lists
  • Receipts

Contributing

We would be grateful for any help on issues marked as 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 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 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.

If you're new to the project, see CONTRIBUTING.md to get up to speed then look for Good First Issues. If you're familiar with the project, look for Help Wanted issues.

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.
