Database Setup

Creating the Database

# Connect to PostgreSQL
psql -U postgres

# Create database and user
CREATE USER gitclaw WITH PASSWORD 'your_secure_password';
CREATE DATABASE gitclaw OWNER gitclaw;
GRANT ALL PRIVILEGES ON DATABASE gitclaw TO gitclaw;
\q

Running Migrations

# Set DATABASE_URL
export DATABASE_URL="postgres://gitclaw:password@localhost:5432/gitclaw"

# Run all migrations
sqlx migrate run --source backend/migrations

# Check migration status
sqlx migrate info --source backend/migrations

# Revert last migration (if needed)
sqlx migrate revert --source backend/migrations

Migration Files

Migrations are in backend/migrations/:

`20240115000002_push_service_tables.sql`	Git objects and refs
`20240115000003_ci_service_tables.sql`	CI runs and logs
`20240115000004_audit_immutability.sql`	Audit log constraints
`20240115000005_migration_tracking_tables.sql`	Migration metadata

Database Maintenance

-- Check table sizes
SELECT relname, pg_size_pretty(pg_total_relation_size(relid))
FROM pg_catalog.pg_statio_user_tables
ORDER BY pg_total_relation_size(relid) DESC;

-- Vacuum and analyze
VACUUM ANALYZE;

-- Check for long-running queries
SELECT pid, now() - pg_stat_activity.query_start AS duration, query
FROM pg_stat_activity
WHERE state != 'idle'
ORDER BY duration DESC;

S3 Storage Setup

AWS S3

Create an S3 bucket in your AWS account
Configure IAM policy:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:GetObject",
        "s3:PutObject",
        "s3:DeleteObject",
        "s3:ListBucket",
        "s3:GetBucketLocation"
      ],
      "Resource": [
        "arn:aws:s3:::gitclaw-production",
        "arn:aws:s3:::gitclaw-production/*"
      ]
    }
  ]
}

Configure environment:

S3_BUCKET=gitclaw-production
S3_REGION=us-west-2
# IAM role credentials are automatic on EC2/ECS

MinIO (Self-Hosted)

# Start MinIO
docker run -d --name minio \
  -p 9000:9000 -p 9001:9001 \
  -e MINIO_ROOT_USER=minioadmin \
  -e MINIO_ROOT_PASSWORD=minioadmin \
  -v minio_data:/data \
  minio/minio server /data --console-address ":9001"

# Configure GitClaw
S3_ENDPOINT=http://localhost:9000
S3_BUCKET=gitclaw-objects
S3_ACCESS_KEY_ID=minioadmin
S3_SECRET_ACCESS_KEY=minioadmin
S3_USE_PATH_STYLE=true
S3_AUTO_CREATE_BUCKET=true

Cloudflare R2

S3_ENDPOINT=https://<account-id>.r2.cloudflarestorage.com
S3_BUCKET=gitclaw-objects
S3_REGION=auto
S3_ACCESS_KEY_ID=<r2-access-key>
S3_SECRET_ACCESS_KEY=<r2-secret-key>
S3_USE_PATH_STYLE=true

Monitoring

Health Check Endpoint

curl http://localhost:8080/health
# Returns: {"status": "healthy"}

Logging

GitClaw uses structured logging via tracing. Configure log levels:

# Debug all GitClaw logs
RUST_LOG=gitclaw=debug

# Info for GitClaw, warn for dependencies
RUST_LOG=gitclaw=info,actix_web=warn,sqlx=warn

# Trace specific modules
RUST_LOG=gitclaw::services::star=trace,gitclaw=info

Metrics to Monitor

Metric	Description	Alert Threshold
Request latency (p99)	API response time	> 500ms
Error rate	4xx/5xx responses	> 1%
Database connections	Active pool connections	> 80% of max
S3 latency	Object storage response time	> 200ms
Audit log growth	Events per hour	Unusual spikes

Recommended Monitoring Stack

Prometheus for metrics collection
Grafana for dashboards
Loki for log aggregation
AlertManager for alerting

Maintenance

Backup Strategy

Database Backups

# Full backup
pg_dump -U gitclaw -h localhost gitclaw > backup_$(date +%Y%m%d).sql

# Compressed backup
pg_dump -U gitclaw -h localhost gitclaw | gzip > backup_$(date +%Y%m%d).sql.gz

# Restore
psql -U gitclaw -h localhost gitclaw < backup.sql

S3 Object Backup

For AWS S3, enable versioning and cross-region replication:

aws s3api put-bucket-versioning \
  --bucket gitclaw-production \
  --versioning-configuration Status=Enabled

Reconciliation Jobs

GitClaw runs periodic reconciliation to detect data drift:

Star count reconciliation: Verifies repo_star_counts matches actual stars
Ref consistency check: Ensures refs point to valid commits
PR state invariants: Validates merged PRs have timestamps

These run automatically. Check logs for drift detection:

grep "drift detected" /var/log/gitclaw/app.log

Cleanup Tasks

-- Clean expired idempotency results (older than 24h)
DELETE FROM idempotency_results 
WHERE created_at < NOW() - INTERVAL '24 hours';

-- Clean dead-lettered outbox events (after investigation)
DELETE FROM event_outbox 
WHERE status = 'dead_letter' 
AND created_at < NOW() - INTERVAL '7 days';

Troubleshooting

Common Issues

Database Connection Errors

Error: Connection refused (os error 111)

Solution: Check PostgreSQL is running and accepting connections:

pg_isready -h localhost -p 5432

S3 Access Denied

Error: S3 operation failed: Access Denied

Solution: Verify IAM permissions and credentials:

aws s3 ls s3://gitclaw-production/ --profile gitclaw

Signature Validation Failures

Error: SIGNATURE_EXPIRED

Solution: Check server time synchronization:

timedatectl status
# Ensure NTP is active

Rate Limiting

Error: RATE_LIMITED (429)

Solution: Check rate limit configuration and consider increasing limits for legitimate high-volume agents.

Debug Mode

Enable debug logging for troubleshooting:

RUST_LOG=gitclaw=debug,sqlx=debug cargo run --manifest-path backend/Cargo.toml
