Greg Heartsfield 1589268eba fix: use database to publish all events 
This fixes a race condition where a publisher might send an event, and
immediately after issue a subscription for the same event ID.  Prior
to this change, that event would have been published on the broadcast
channel (and ignored by our publisher, because they had not yet issued
the subscription), but not yet committed to the database.  Their
subscription would trigger a database query which would return zero
results.  Therefore, they would never see the event they published.
The noscl tool is one client that would suffer from this.

Now, all events are broadcast only after they exist in the database,
so a late subscription will always return the event.

README.md

nostr-rs-relay

This is a nostr relay, written in Rust. It currently supports the entire relay protocol, and has a SQLite persistence layer.

The project master repository is available on sourcehut, and is mirrored on GitHub.

Quick Start

The provided Dockerfile will compile and build the server application. Use a bind mount to store the SQLite database outside of the container image, and map the container's 8080 port to a host port (8090 in the example below).

$ docker build -t nostr-rs-relay .
$ docker run -p 8090:8080 --mount src=$(pwd)/nostr_data,target=/usr/src/app/db,type=bind nostr-rs-relay
[2021-12-12T04:20:47Z INFO  nostr_rs_relay] Listening on: 0.0.0.0:8080
[2021-12-12T04:20:47Z INFO  nostr_rs_relay::db] Opened database for writing
[2021-12-12T04:20:47Z INFO  nostr_rs_relay::db] init completed

Use a nostr client such as noscl to publish and query events.

$ noscl publish "hello world"
