- Enable MSC4242 complement tests - Fix an issue which caused cascade rejections to not be applied to events in the /send_join response becau se we didn't remember in-memory which events were rejected. - Accept rejected events in the /send_join response, it gives us a bit of robustness at no safety cost. - Recalculate room state if backfilled events caused the state DAG fwd extrems to change. - Don't filter out already seen events from event_map, so the statement "the event_map is the complete stat e DAG" still holds. - Add validation to length of prev_state_events - Don't validate auth_events length for state DAG events as it is done too early, before we've had time to calculate the auth events (and validation is moot anyway given it isn't attacker controlled anymore) - Let backfilled events update state dag fwd extrems - Add test for edge case with backfilled state events
Unified Complement image for Synapse
This is an image for testing Synapse with the Complement integration test suite. It contains some insecure defaults that are only suitable for testing purposes, so please don't use this image for a production server.
This multi-purpose image is built on top of Dockerfile-workers in the parent directory
and can be switched using environment variables between the following configurations:
- Monolithic Synapse with SQLite (default, or
SYNAPSE_COMPLEMENT_DATABASE=sqlite) - Monolithic Synapse with Postgres (
SYNAPSE_COMPLEMENT_DATABASE=postgres) - Workerised Synapse with Postgres (
SYNAPSE_COMPLEMENT_DATABASE=postgresandSYNAPSE_COMPLEMENT_USE_WORKERS=true)
The image is self-contained; it contains an integrated Postgres, Redis and Nginx.
How to get Complement to pass the environment variables through
To pass these environment variables, use Complement's COMPLEMENT_SHARE_ENV_PREFIX
variable to configure an environment prefix to pass through, then prefix the above options
with that prefix.
Example:
COMPLEMENT_SHARE_ENV_PREFIX=PASS_ PASS_SYNAPSE_COMPLEMENT_DATABASE=postgres
Consult scripts-dev/complement.sh in the repository root for a real example.
How to modify homeserver.yaml for Complement tests
It's common for MSCs to be gated behind a feature flag like this:
experimental_features:
faster_joins: true
To modify this for the Complement image, modify ./conf/workers-shared-extra.yaml.j2. Despite the name,
this will affect non-worker mode as well. Remember to rebuild the image (so don't use -e if using
complement.sh).
