Database Naming Convention + +Database files are named using the relay's public key: +``` +build/.db +``` + +Example: `build/a1b2c3d4e5f6...789.db` + +This ensures: +- Unique database per relay instance +- Easy identification of relay identity +- No conflicts when running multiple relays + +### 3. Port Binding Strategy + +The relay uses a sophisticated port binding strategy: + +1. **Configuration Priority**: + - CLI `--port` override (highest priority) + - Database config `relay_port` value + - Default `DEFAULT_PORT` (8888) + +2. **Fallback Behavior**: + - In normal mode: tries next 10 ports if unavailable + - In strict mode (`--strict-port`): fails immediately + +3. **Pre-checking**: + - Uses `check_port_available()` before libwebsockets binding + - Sets `SO_REUSEADDR` to match libwebsockets behavior + - Prevents false unavailability from TIME_WAIT states + +### 4. Configuration Cache Timeout + +Default cache timeout: **5 minutes (300 seconds)** + +Can be customized via: +- Environment variable: `GINX_CACHE_TIMEOUT=` +- Database config: `cache_timeout` key +- Disable caching: `GINX_NO_CACHE=1` + +### 5. WAL Mode for SQLite + +The relay uses Write-Ahead Logging (WAL) mode for better concurrency: + +```sql +PRAGMA journal_mode=WAL; +``` + +Benefits: +- Readers don't block writers +- Writers don't block readers +- Better performance for concurrent access + +Considerations: +- Creates `-wal` and `-shm` files alongside database +- Requires periodic checkpointing +- Not suitable for network filesystems + +### 6. Schema Versioning + +Current schema version: **6** + +Schema migrations are handled automatically during `init_database()`: +```c +// Check current schema version +SELECT version FROM schema_version ORDER BY version DESC LIMIT 1; + +// Apply migrations if needed +if (current_version < LATEST_VERSION) { + apply_schema_migrations(current_version, LATEST_VERSION); +} +``` + +--- + +## Troubleshooting Startup Issues + +### Common Issues and Solutions + +#### 1. Port Already in Use + +**Symptom**: `Failed to bind to port 8888` + +**Solutions**: +- Use `--port ` to specify different port +- Kill existing process: `pkill -f c_relay_` +- Force kill port: `fuser -k 8888/tcp` +- Use `--strict-port` to fail fast instead of trying fallback ports + +#### 2. Database Lock + +**Symptom**: `database is locked` + +**Solutions**: +- Kill existing relay processes +- Remove WAL files: `rm build/*.db-wal build/*.db-shm` +- Check for stale processes: `ps aux | grep c_relay_` + +#### 3. Missing Admin Private Key + +**Symptom**: Cannot send admin commands + +**Solutions**: +- If lost, must delete database and restart +- Use `--admin-pubkey` on first startup to use existing key +- Save admin private key immediately on first startup + +#### 4. Configuration Not Loading + +**Symptom**: Relay uses default values instead of configured values + +**Solutions**: +- Check cache timeout: `GINX_CACHE_TIMEOUT` environment variable +- Force cache refresh: restart relay +- Verify config table: `SELECT * FROM config;` +- Check cache validity: `g_unified_cache.cache_valid` + +#### 5.
