Comprehensive Negentropy Sync Test Suite

Tests NIP-77 negentropy synchronization between ORLY and strfry relays.

Test Scenarios

1. strfry as Client, ORLY as Server (Phases 1-6)

Uses strfry sync command to test:

• Push: strfry → orly-relay-1
• Pull: strfry ← orly-relay-1
• Bidirectional: strfry ↔ orly-relay-1

2. ORLY as Client, ORLY as Server (Phases 7-10)

Uses orly sync CLI with a temporary Badger DB as a bridge:

• relay-1 → relay-2: orly CLI pulls from relay-1, pushes to relay-2
• relay-2 → relay-1: orly CLI pushes relay-2 events to relay-1
• Three-way consistency: strfry, relay-1, relay-2 converge

                          │ orly-relay-2 │
                          │   (3335)     │
                          └──────────────┘

The orly sync CLI runs inside the test-runner container. It opens a temporary Badger database and uses NIP-77 negentropy to sync with each relay, effectively bridging events between the two ORLY instances.

Quick Start

Prerequisites

• Docker and Docker Compose

Run All Tests

cd tests/negentropy

# Build all images
docker compose build

# Start infrastructure
docker compose up -d

# Run comprehensive tests
./comprehensive-test.sh

# Or with verbose output
./comprehensive-test.sh --verbose

# Clean up
docker compose down -v

Manual Operations

# Generate events
docker compose exec -T test-runner event-generator -count 500 -relay ws://strfry:7777

# strfry sync (strfry as client, ORLY as server)
docker compose exec -T strfry /app/strfry --config=/etc/strfry.conf sync ws://orly-relay-1:3334 --dir down

# orly sync (orly CLI as client, any relay as server)
docker compose exec -T test-runner orly sync ws://orly-relay-1:3334 --data-dir /tmp/sync-db

# Manual event inspection
echo '["REQ", "test", {"limit": 10}]' | websocat ws://localhost:7777
echo '["REQ", "test", {"limit": 10}]' | websocat ws://localhost:3334
echo '["REQ", "test", {"limit": 10}]' | websocat ws://localhost:3335

Test Parameters

• Seed Events: 200 per relay
• Extra Events: 100
• Event Kinds: 0, 1, 3, 1984, 10000, 10001, 30023
• Batch Size: 50 events per batch
• Authors: 3 test keypairs (alice, bob, carol)

Event Distribution

Kind	Percentage	Description
1	60%	Short text notes
0	15%	Metadata
3	10%	Contacts
1984	5%	Reports
10000	5%	Mute lists
10001	3%	Pin lists
30023	2%	Long-form articles

Troubleshooting

Check service health

docker compose ps
docker compose logs -f strfry
docker compose logs -f orly-relay-1
docker compose logs -f orly-relay-2

Reset test data

docker compose down -v
docker compose up -d
