# AGENTS.md - AI Agent Integration Guide for Architect Mode
|
||||
|
||||
**Project-Specific Information for AI Agents Working with C-Relay in Architect Mode**
|
||||
|
||||
## Critical Architecture Understanding
|
||||
|
||||
### System Architecture Overview
|
||||
C-Relay implements a **unique event-based configuration architecture** that fundamentally differs from traditional Nostr relays:
|
||||
|
||||
```
|
||||
┌─────────────────┐ ┌──────────────────┐ ┌─────────────────┐
|
||||
│ WebSocket │ │ Configuration │ │ Database │
|
||||
│ + HTTP │◄──►│ Event System │◄──►│ (SQLite) │
|
||||
│ (Port 8888) │ │ (Kind 33334) │ │ Schema v4 │
|
||||
└─────────────────┘ └──────────────────┘ └─────────────────┘
|
||||
│ │ │
|
||||
▼ ▼ ▼
|
||||
┌─────────────────┐ ┌──────────────────┐ ┌─────────────────┐
|
||||
│ nostr_core_lib │ │ Admin Key │ │ Event Storage │
|
||||
│ (Crypto/Sigs) │ │ Management │ │ + Subscriptions │
|
||||
└─────────────────┘ └──────────────────┘ └─────────────────┘
|
||||
```
|
||||
|
||||
### Core Architectural Principles
|
||||
|
||||
#### 1. Event-Driven Configuration
|
||||
**Design Philosophy**: Configuration as cryptographically signed events rather than files
|
||||
- **Benefits**: Auditability, remote management, tamper-evidence
|
||||
- **Trade-offs**: Complexity in configuration changes, admin key management burden
|
||||
- **Implementation**: Kind 33334 events stored in same database as relay events
|
||||
|
||||
#### 2. Identity-Based Database Naming
|
||||
**Design Philosophy**: Database file named by relay's generated public key
|
||||
- **Benefits**: Prevents database conflicts, enables multi-relay deployments
|
||||
- **Trade-offs**: Cannot predict database filename, complicates backup strategies
|
||||
- **Implementation**: `<relay_pubkey>.db` created in build/ directory
|
||||
|
||||
#### 3. Single-Binary Deployment
|
||||
**Design Philosophy**: All functionality embedded in one executable
|
||||
- **Benefits**: Simple deployment, no external dependencies to manage
|
||||
- **Trade-offs**: Larger binary size, harder to modularize
|
||||
- **Implementation**: SQL schema embedded as header file, nostr_core_lib as submodule
|
||||
|
||||
#### 4. Dual-Protocol Support
|
||||
**Design Philosophy**: WebSocket (Nostr) and HTTP (NIP-11) on same port
|
||||
- **Benefits**: Simplified port management, reduced infrastructure complexity
|
||||
- **Trade-offs**: Protocol detection overhead, libwebsockets dependency
|
||||
- **Implementation**: Request routing based on HTTP headers and upgrade requests
|
||||
|
||||
## Architectural Decision Analysis
|
||||
|
||||
### Configuration System Design
|
||||
**Traditional Approach vs C-Relay:**
|
||||
```
|
||||
Traditional: C-Relay:
|
||||
config.json → kind 33334 events
|
||||
ENV variables → cryptographically signed tags
|
||||
File watching → database polling/restart
|
||||
```
|
||||
|
||||
**Implications for Extensions:**
|
||||
- Configuration changes require event signing capabilities
|
||||
- No hot-reloading without architectural changes
|
||||
- Admin key loss = complete database reset required
|
||||
|
||||
### Database Architecture Decisions
|
||||
**Schema Design Philosophy:**
|
||||
- **Event Tags as JSON**: Separate table with JSON column instead of normalized relations
|
||||
- **Application-Level Filtering**: NIP-40 expiration handled in C, not SQL
|
||||
- **Embedded Schema**: Version 4 schema compiled into binary
|
||||
|
||||
**Scaling Considerations:**
|
||||
- SQLite suitable for small-to-medium relays (< 10k concurrent connections)
|
||||
- Single-writer limitation of SQLite affects write-heavy workloads
|
||||
- JSON tag storage optimizes for read performance over write normalization
|
||||
|
||||
### Memory Management Architecture
|
||||
**Thread Safety Model:**
|
||||
- Global subscription manager with mutex protection
|
||||
- Per-client subscription limits enforced in memory
|
||||
- WebSocket connection state managed by libwebsockets
|
||||
|
||||
**Resource Management:**
|
||||
- JSON objects use reference counting (jansson library)
|
||||
- String duplication pattern for configuration values
|
||||
- Automatic cleanup on client disconnect
|
||||
|
||||
## Architectural Extension Points
|
||||
|
||||
### Adding New Configuration Options
|
||||
**Required Changes:**
|
||||
1. Update [`default_config_event.h`](src/default_config_event.h) template
|
||||
2. Add parsing logic in [`config.c`](src/config.c) `load_config_from_database()`
|
||||
3. Add global config struct field in [`config.h`](src/config.h)
|
||||
4. Update documentation in [`docs/configuration_guide.md`](docs/configuration_guide.md)
|
||||
|
||||
### Adding New NIP Support
|
||||
**Integration Pattern:**
|
||||
1. Event validation in [`request_validator.c`](src/request_validator.c)
|
||||
2. Protocol handling in [`main.c`](src/main.c) WebSocket callback
|
||||
3. Database storage considerations in schema
|
||||
4. Add test in `tests/` directory
|
||||
|
||||
### Scaling Architecture
|
||||
**Current Limitations:**
|
||||
- Single process, no horizontal scaling
|
||||
- SQLite single-writer bottleneck
|
||||
- Memory-based subscription management
|
||||
|
||||
**Potential Extensions:**
|
||||
- Redis for subscription state sharing
|
||||
- PostgreSQL for better concurrent write performance
|
||||
- Load balancer for read scaling with multiple instances
|
||||
|
||||
## Deployment Architecture Patterns
|
||||
|
||||
### Development Deployment
|
||||
```
|
||||
Developer Machine:
|
||||
├── ./make_and_restart_relay.sh
|
||||
├── build/c_relay_x86
|
||||
├── build/<relay_pubkey>.db
|
||||
└── relay.log
|
||||
```
|
||||
|
||||
### Production SystemD Deployment
|
||||
```
|
||||
/opt/c-relay/:
|
||||
├── c_relay_x86
|
||||
├── <relay_pubkey>.db
|
||||
├── systemd service (c-relay.service)
|
||||
└── c-relay user isolation
|
||||
```
|
||||
|
||||
### Container Deployment Architecture
|
||||
```
|
||||
Container:
|
||||
├── Multi-stage build (deps + binary)
|
||||
├── Volume mount for database persistence
|
||||
├── Health checks via NIP-11 endpoint
|
||||
└── Signal handling for graceful shutdown
|
||||
```
|
||||
|
||||
### Reverse Proxy Architecture
|
||||
```
|
||||
Internet → Nginx/HAProxy → C-Relay
|
||||
├── WebSocket upgrade handling
|
||||
├── SSL termination
|
||||
└── Rate limiting
|
||||
```
|
||||
|
||||
## Security Architecture Considerations
|
||||
|
||||
### Key Management Design
|
||||
**Admin Key Security Model:**
|
||||
- Generated once, displayed once, never stored
|
||||
- Required for all configuration changes
|
||||
- Loss requires complete database reset
|
||||
|
||||
**Relay Identity Model:**
|
||||
- Separate keypair for relay identity
|
||||
- Public key used for database naming
|
||||
- Private key never exposed to clients
|
||||
|
||||
### Event Validation Pipeline
|
||||
```
|
||||
WebSocket Input → JSON Parse → Schema Validate → Signature Verify → Store
|
||||
↓ ↓ ↓
|
||||
reject reject reject success
|
||||
```
|
||||
|
||||
### Attack Surface Analysis
|
||||
**Network Attack Vectors:**
|
||||
- WebSocket connection flooding (mitigated by libwebsockets limits)
|
||||
- JSON parsing attacks (handled by jansson library bounds checking)
|
||||
- SQLite injection (prevented by prepared statements)
|
||||
|
||||
**Configuration Attack Vectors:**
|
||||
- Admin key compromise (complete relay control)
|
||||
- Event signature forgery (prevented by nostr_core_lib validation)
|
||||
- Replay attacks (event timestamp validation required)
|
||||
|
||||
## Non-Obvious Architectural Considerations
|
||||
|
||||
### Database Evolution Strategy
|
||||
**Current Limitations:**
|
||||
- Schema changes require database recreation
|
||||
- No migration system for configuration events
|
||||
- Version 4 schema embedded in binary
|
||||
|
||||
**Future Architecture Needs:**
|
||||
- Schema versioning and migration system
|
||||
- Backward compatibility for configuration events
|
||||
- Database backup/restore procedures
|
||||
|
||||
### Configuration Event Lifecycle
|
||||
**Event Flow:**
|
||||
```
|
||||
Admin Signs Event → WebSocket Submit → Validate → Store → Restart Required
|
||||
↓ ↓ ↓
|
||||
Signature Check Database Config Reload
|
||||
```
|
||||
|
||||
**Architectural Implications:**
|
||||
- No hot configuration reloading
|
||||
- Configuration changes require planned downtime
|
||||
- Event ordering matters for multiple simultaneous changes
|
||||
|
||||
### Cross-Architecture Deployment
|
||||
**Build System Architecture:**
|
||||
- Auto-detection of host architecture
|
||||
- Cross-compilation support for ARM64
|
||||
- Architecture-specific binary outputs
|
||||
|
||||
**Deployment Implications:**
|
||||
- Binary must match target architecture
|
||||
- Dependencies must be available for target architecture
|
||||
- Debug tooling architecture-specific
|
||||
|
||||
### Performance Architecture Characteristics
|
||||
**Bottlenecks:**
|
||||
1. **SQLite Write Performance**: Single writer limitation
|
||||
2. **JSON Parsing**: Per-event parsing overhead
|
||||
3. **Signature Validation**: Cryptographic operations per event
|
||||
4. **Memory Management**: JSON object lifecycle management
|
||||
|
||||
**Optimization Points:**
|
||||
- Prepared statement reuse
|
||||
- Connection pooling for concurrent reads
|
||||
- Event batching for bulk operations
|
||||
- Subscription indexing strategies
|
||||
|
||||
### Integration Architecture Patterns
|
||||
**Monitoring Integration:**
|
||||
- NIP-11 endpoint for health checks
|
||||
- Log file monitoring for operational metrics
|
||||
- Database query monitoring for performance
|
||||
- Process monitoring for resource usage
|
||||
|
||||
**Backup Architecture:**
|
||||
- Database file backup (SQLite file copy)
|
||||
- Configuration event export/import
|
||||
- Admin key secure storage (external to relay)
|
||||
|
||||
### Future Extension Architectures
|
||||
**Multi-Relay Coordination:**
|
||||
- Database sharding by event kind
|
||||
- Cross-relay event synchronization
|
||||
- Distributed configuration management
|
||||
|
||||
**Plugin Architecture Possibilities:**
|
||||
- Event processing pipeline hooks
|
||||
- Custom validation plugins
|
||||
- External authentication providers
|
||||
|
||||
**Scaling Architecture Options:**
|
||||
- Read replicas with PostgreSQL migration
|
||||
- Event stream processing with message queues
|
||||
- Microservice decomposition (auth, storage, validation)
|
||||
|
||||
## Architectural Anti-Patterns to Avoid
|
||||
|
||||
1. **Configuration File Addition**: Breaks event-based config paradigm
|
||||
2. **Direct Database Modification**: Bypasses signature validation
|
||||
3. **Hard-Coded Ports**: Conflicts with auto-fallback system
|
||||
4. **Schema Modifications**: Requires database recreation
|
||||
5. **Admin Key Storage**: Violates security model
|
||||
6. **Blocking Operations**: Interferes with WebSocket event loop
|
||||
7. **Memory Leaks**: JSON objects must be properly reference counted
|
||||
8. **Thread Unsafe Operations**: Global state requires proper synchronization
|
||||
|
||||
## Architecture Decision Records (Implicit)
|
||||
|
||||
### Decision: Event-Based Configuration
|
||||
**Context**: Traditional config files vs. cryptographic auditability
|
||||
**Decision**: Store configuration as signed Nostr events
|
||||
**Consequences**: Complex configuration changes, enhanced security, remote management capability
|
||||
|
||||
### Decision: SQLite Database
|
||||
**Context**: Database choice for relay storage
|
||||
**Decision**: Embedded SQLite with JSON tag storage
|
||||
**Consequences**: Simple deployment, single-writer limitation, application-level filtering
|
||||
|
||||
### Decision: Single Binary Deployment
|
||||
**Context**: Dependency management vs. deployment simplicity
|
||||
**Decision**: Embed all dependencies and schema in binary
|
||||
**Consequences**: Larger binary, simple deployment, version coupling
|
||||
|
||||
### Decision: Dual Protocol Support
|
||||
**Context**: WebSocket for Nostr, HTTP for NIP-11
|
||||
**Decision**: Same port serves both protocols
|
||||
**Consequences**: Simplified deployment, protocol detection overhead, libwebsockets dependency
|
||||
|
||||
These architectural decisions form the foundation of C-Relay's unique approach to Nostr relay implementation and should be carefully considered when planning extensions or modifications.

# AGENTS.md - AI Agent Integration Guide
|
||||
|
||||
**Project-Specific Information for AI Agents Working with C-Relay**
|
||||
|
||||
## Critical Build Commands
|
||||
|
||||
### Primary Build Command
|
||||
```bash
|
||||
./make_and_restart_relay.sh
|
||||
```
|
||||
**Never use `make` directly.** The project requires the custom restart script which:
|
||||
- Handles database preservation/cleanup based on flags
|
||||
- Manages architecture-specific binary detection (x86/ARM64)
|
||||
- Performs automatic process cleanup and port management
|
||||
- Starts relay in background with proper logging
|
||||
|
||||
### Architecture-Specific Binary Outputs
|
||||
- **x86_64**: `./build/c_relay_x86`
|
||||
- **ARM64**: `./build/c_relay_arm64`
|
||||
- **Other**: `./build/c_relay_$(ARCH)`
|
||||
|
||||
### Database File Naming Convention
|
||||
- **Format**: `<relay_pubkey>.db` (NOT `.nrdb` as shown in docs)
|
||||
- **Location**: Created in `build/` directory during execution
|
||||
- **Cleanup**: Use `--preserve-database` flag to retain between builds
|
||||
|
||||
## Critical Integration Issues
|
||||
|
||||
### Event-Based Configuration System
|
||||
- **No traditional config files** - all configuration stored in config table
|
||||
- Admin private key shown **only once** on first startup
|
||||
- Configuration changes require cryptographically signed events
|
||||
- Database path determined by generated relay pubkey
|
||||
|
||||
### First-Time Startup Sequence
|
||||
1. Relay generates admin keypair and relay keypair
|
||||
2. Creates database file with relay pubkey as filename
|
||||
3. Stores default configuration in config table
|
||||
4. **CRITICAL**: Admin private key displayed once and never stored on disk
|
||||
|
||||
### Port Management
|
||||
- Default port 8888 with automatic fallback (8889, 8890, etc.)
|
||||
- Script performs port availability checking before libwebsockets binding
|
||||
- Process cleanup includes force-killing processes on port 8888
|
||||
|
||||
### Database Schema Dependencies
|
||||
- Uses embedded SQL schema (`sql_schema.h`)
|
||||
- Schema version 4 with JSON tag storage
|
||||
- **Critical**: Event expiration filtering done at application level, not SQL level
|
||||
|
||||
### Admin API Event Structure
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [
|
||||
["p", "<relay_pubkey>"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Configuration Commands** (encrypted in content):
|
||||
- `["relay_description", "My Relay"]`
|
||||
- `["max_subscriptions_per_client", "25"]`
|
||||
- `["pow_min_difficulty", "16"]`
|
||||
|
||||
**Auth Rule Commands** (encrypted in content):
|
||||
- `["blacklist", "pubkey", "hex_pubkey_value"]`
|
||||
- `["whitelist", "pubkey", "hex_pubkey_value"]`
|
||||
|
||||
**Query Commands** (encrypted in content):
|
||||
- `["auth_query", "all"]`
|
||||
- `["system_command", "system_status"]`
|
||||
|
||||
### Process Management
|
||||
```bash
|
||||
# Kill existing relay processes
|
||||
pkill -f "c_relay_"
|
||||
|
||||
# Check running processes
|
||||
ps aux | grep c_relay_
|
||||
|
||||
# Force kill port binding
|
||||
fuser -k 8888/tcp
|
||||
```
|
||||
|
||||
### Cross-Compilation Specifics
|
||||
- ARM64 requires explicit dependency installation: `make install-arm64-deps`
|
||||
- Uses `aarch64-linux-gnu-gcc` with specific library paths
|
||||
- PKG_CONFIG_PATH must be set for ARM64: `/usr/lib/aarch64-linux-gnu/pkgconfig`
|
||||
|
||||
### Testing Integration
|
||||
- Tests expect relay running on default port
|
||||
- Use `tests/quick_error_tests.sh` for validation
|
||||
- Event configuration tests: `tests/event_config_tests.sh`
|
||||
|
||||
### SystemD Integration Considerations
|
||||
- Service runs as `c-relay` user in `/opt/c-relay`
|
||||
- Database files created in WorkingDirectory automatically
|
||||
- No environment variables needed (event-based config)
|
||||
- Resource limits: 65536 file descriptors, 4096 processes
|
||||
|
||||
### Development vs Production Differences
|
||||
- Development: `make_and_restart_relay.sh` (default database cleanup)
|
||||
- Production: `make_and_restart_relay.sh --preserve-database`
|
||||
- Debug build requires manual gdb attachment to architecture-specific binary
|
||||
|
||||
### Critical File Dependencies
|
||||
- `nostr_core_lib/` submodule must be initialized and built first
|
||||
- Version header auto-generated from git tags: `src/version.h`
|
||||
- Schema embedded in binary from `src/sql_schema.h`
|
||||
|
||||
### WebSocket Protocol Specifics
|
||||
- Supports both WebSocket (Nostr protocol) and HTTP (NIP-11)
|
||||
- NIP-11 requires `Accept: application/nostr+json` header
|
||||
- CORS headers automatically added for NIP-11 compliance
|
||||
|
||||
### Memory Management Notes
|
||||
- Persistent subscription system with thread-safe global manager
|
||||
- Per-session subscription limits enforced
|
||||
- Event filtering done at C level, not SQL level for NIP-40 expiration
|
||||
|
||||
### Configuration Override Behavior
|
||||
- CLI port override only affects first-time startup
|
||||
- After database creation, all config comes from events
|
||||
- Database path cannot be changed after initialization
|
||||
|
||||
## Non-Obvious Pitfalls
|
||||
|
||||
1. **Database Lock Issues**: Script handles SQLite locking by killing existing processes first
|
||||
2. **Port Race Conditions**: Pre-check + libwebsockets binding can still fail due to timing
|
||||
3. **Key Loss**: Admin private key loss requires complete database deletion and restart
|
||||
4. **Architecture Detection**: Build system auto-detects but cross-compilation requires manual setup
|
||||
5. **Event Storage**: Ephemeral events (kind 20000-29999) accepted but not stored
|
||||

## 🔧 Administrator API
|
||||
|
||||
C-Relay uses an innovative **event-based administration system** where all configuration and management commands are sent as signed Nostr events using the admin private key generated during first startup. All admin commands use **NIP-44 encrypted command arrays** for security and compatibility.
|
||||
|
||||
### Authentication
|
||||
|
||||
All admin commands require signing with the admin private key displayed during first-time startup. **Save this key securely** - it cannot be recovered and is needed for all administrative operations.
|
||||
|
||||
### Event Structure
|
||||
|
||||
All admin commands use the same unified event structure with NIP-44 encrypted content:
|
||||
|
||||
**Admin Command Event:**
|
||||
```json
|
||||
{
|
||||
"id": "event_id",
|
||||
"pubkey": "admin_public_key",
|
||||
"created_at": 1234567890,
|
||||
"kind": 23456,
|
||||
"content": "AqHBUgcM7dXFYLQuDVzGwMST1G8jtWYyVvYxXhVGEu4nAb4LVw...",
|
||||
"tags": [
|
||||
["p", "relay_public_key"]
|
||||
],
|
||||
"sig": "event_signature"
|
||||
}
|
||||
```
|
||||
|
||||
The `content` field contains a NIP-44 encrypted JSON array representing the command.
|
||||
|
||||
**Admin Response Event:**
|
||||
```json
|
||||
["EVENT", "temp_sub_id", {
|
||||
"id": "response_event_id",
|
||||
"pubkey": "relay_public_key",
|
||||
"created_at": 1234567890,
|
||||
"kind": 23457,
|
||||
"content": "BpKCVhfN8eYtRmPqSvWxZnMkL2gHjUiOp3rTyEwQaS5dFg...",
|
||||
"tags": [
|
||||
["p", "admin_public_key"]
|
||||
],
|
||||
"sig": "response_event_signature"
|
||||
}]
|
||||
```
|
||||
|
||||
The `content` field contains a NIP-44 encrypted JSON response object.
|
||||
|
||||
### Admin Commands
|
||||
|
||||
All commands are sent as NIP-44 encrypted JSON arrays in the event content. The following table lists all available commands:
|
||||
|
||||

# C Nostr Relay Database
|
||||
|
||||
This directory contains the SQLite database schema and initialization scripts for the C Nostr Relay implementation.
|
||||
|
||||
## Files
|
||||
|
||||
- **`schema.sql`** - Complete database schema based on nostr-rs-relay v18
|
||||
- **`init.sh`** - Database initialization script
|
||||
- **`c_nostr_relay.db`** - SQLite database file (created after running init.sh)
|
||||
|
||||
## Quick Start
|
||||
|
||||
1. **Initialize the database:**
|
||||
```bash
|
||||
cd db
|
||||
./init.sh
|
||||
```
|
||||
|
||||
2. **Force reinitialize (removes existing database):**
|
||||
```bash
|
||||
./init.sh --force
|
||||
```
|
||||
|
||||
3. **Initialize with optimization and info:**
|
||||
```bash
|
||||
./init.sh --info --optimize
|
||||
```
|
||||
|
||||
## Database Schema
|
||||
|
||||
The schema is fully compatible with the Nostr protocol and includes:
|
||||
|
||||
### Core Tables
|
||||
|
||||
- **`event`** - Main event storage with all Nostr event data
|
||||
- **`tag`** - Denormalized tag index for efficient queries
|
||||
- **`user_verification`** - NIP-05 verification tracking
|
||||
- **`account`** - User account management (optional)
|
||||
- **`invoice`** - Lightning payment tracking (optional)
|
||||
|
||||
### Key Features
|
||||
|
||||
- ✅ **NIP-01 compliant** - Full basic protocol support
|
||||
- ✅ **Replaceable events** - Supports kinds 0, 3, 10000-19999
|
||||
- ✅ **Parameterized replaceable** - Supports kinds 30000-39999 with `d` tags
|
||||
- ✅ **Event deletion** - NIP-09 soft deletion with `hidden` column
|
||||
- ✅ **Event expiration** - NIP-40 automatic cleanup
|
||||
- ✅ **Authentication** - NIP-42 client authentication
|
||||
- ✅ **NIP-05 verification** - Domain-based identity verification
|
||||
- ✅ **Performance optimized** - Comprehensive indexing strategy
|
||||
|
||||
### Schema Version
|
||||
|
||||
Current version: **v18** (compatible with nostr-rs-relay v18)
|
||||
|
||||
## Database Structure
|
||||
|
||||
### Event Storage
|
||||
```sql
|
||||
CREATE TABLE event (
|
||||
id INTEGER PRIMARY KEY,
|
||||
event_hash BLOB NOT NULL, -- 32-byte SHA256 hash
|
||||
first_seen INTEGER NOT NULL, -- relay receive timestamp
|
||||
created_at INTEGER NOT NULL, -- event creation timestamp
|
||||
expires_at INTEGER, -- NIP-40 expiration
|
||||
author BLOB NOT NULL, -- 32-byte pubkey
|
||||
delegated_by BLOB, -- NIP-26 delegator
|
||||
kind INTEGER NOT NULL, -- event kind
|
||||
hidden INTEGER DEFAULT FALSE, -- soft deletion flag
|
||||
content TEXT NOT NULL -- complete JSON event
|
||||
);
|
||||
```
|
||||
|
||||
### Tag Indexing
|
||||
```sql
|
||||
CREATE TABLE tag (
|
||||
id INTEGER PRIMARY KEY,
|
||||
event_id INTEGER NOT NULL,
|
||||
name TEXT, -- tag name ("e", "p", etc.)
|
||||
value TEXT, -- tag value
|
||||
created_at INTEGER NOT NULL, -- denormalized for performance
|
||||
kind INTEGER NOT NULL -- denormalized for performance
|
||||
);
|
||||
```
|
||||
|
||||
## Performance Features
|
||||
|
||||
### Optimized Indexes
|
||||
- **Hash-based lookups** - `event_hash_index` for O(1) event retrieval
|
||||
- **Author queries** - `author_index`, `author_created_at_index`
|
||||
- **Kind filtering** - `kind_index`, `kind_created_at_index`
|
||||
- **Tag searching** - `tag_covering_index` for efficient tag queries
|
||||
- **Composite queries** - Multi-column indexes for complex filters
|
||||
|
||||
### Query Optimization
|
||||
- **Denormalized tags** - Includes `kind` and `created_at` in tag table
|
||||
- **Binary storage** - BLOBs for hex data (pubkeys, hashes)
|
||||
- **WAL mode** - Write-Ahead Logging for concurrent access
|
||||
- **Automatic cleanup** - Triggers for data integrity
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Operations
|
||||
|
||||
1. **Insert an event:**
|
||||
```sql
|
||||
INSERT INTO event (event_hash, first_seen, created_at, author, kind, content)
|
||||
VALUES (?, ?, ?, ?, ?, ?);
|
||||
```
|
||||
|
||||
2. **Query by author:**
|
||||
```sql
|
||||
SELECT content FROM event
|
||||
WHERE author = ? AND hidden != TRUE
|
||||
ORDER BY created_at DESC;
|
||||
```
|
||||
|
||||
3. **Filter by tags:**
|
||||
```sql
|
||||
SELECT e.content FROM event e
|
||||
JOIN tag t ON e.id = t.event_id
|
||||
WHERE t.name = 'p' AND t.value = ? AND e.hidden != TRUE;
|
||||
```
|
||||
|
||||
### Advanced Queries
|
||||
|
||||
1. **Get replaceable event (latest only):**
|
||||
```sql
|
||||
SELECT content FROM event
|
||||
WHERE author = ? AND kind = ? AND hidden != TRUE
|
||||
ORDER BY created_at DESC LIMIT 1;
|
||||
```
|
||||
|
||||
2. **Tag-based filtering (NIP-01 filters):**
|
||||
```sql
|
||||
SELECT e.content FROM event e
|
||||
WHERE e.id IN (
|
||||
SELECT t.event_id FROM tag t
|
||||
WHERE t.name = ? AND t.value IN (?, ?, ?)
|
||||
) AND e.hidden != TRUE;
|
||||
```
|
||||
|
||||
## Maintenance
|
||||
|
||||
### Regular Operations
|
||||
|
||||
1. **Check database integrity:**
|
||||
```bash
|
||||
sqlite3 c_nostr_relay.db "PRAGMA integrity_check;"
|
||||
```
|
||||
|
||||
2. **Optimize database:**
|
||||
```bash
|
||||
sqlite3 c_nostr_relay.db "PRAGMA optimize; VACUUM; ANALYZE;"
|
||||
```
|
||||
|
||||
3. **Clean expired events:**
|
||||
```sql
|
||||
DELETE FROM event WHERE expires_at <= strftime('%s', 'now');
|
||||
```
|
||||
|
||||
### Monitoring
|
||||
|
||||
1. **Database size:**
|
||||
```bash
|
||||
ls -lh c_nostr_relay.db
|
||||
```
|
||||
|
||||
2. **Table statistics:**
|
||||
```sql
|
||||
SELECT name, COUNT(*) as count FROM (
|
||||
SELECT 'events' as name FROM event UNION ALL
|
||||
SELECT 'tags' as name FROM tag UNION ALL
|
||||
SELECT 'verifications' as name FROM user_verification
|
||||
) GROUP BY name;
|
||||
```
|
||||
|
||||
## Migration Support
|
||||
|
||||
The schema includes a migration system for future updates:
|
||||
|
||||
```sql
|
||||
CREATE TABLE schema_info (
|
||||
version INTEGER PRIMARY KEY,
|
||||
applied_at INTEGER NOT NULL,
|
||||
description TEXT
|
||||
);
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **Input validation** - Always validate event JSON and signatures
|
||||
2. **Rate limiting** - Implement at application level
|
||||
3. **Access control** - Use `account` table for permissions
|
||||
4. **Backup strategy** - Regular database backups recommended
|
||||
|
||||
## Compatibility
|
||||
|
||||
- **SQLite version** - Requires SQLite 3.8.0+
|
||||
- **nostr-rs-relay** - Schema compatible with v18
|
||||
- **NIPs supported** - 01, 02, 05, 09, 10, 11, 26, 40, 42
|
||||
- **C libraries** - Compatible with sqlite3 C API
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Database locked error:**
|
||||
- Ensure proper connection closing in your C code
|
||||
- Check for long-running transactions
|
||||
|
||||
2. **Performance issues:**
|
||||
- Run `PRAGMA optimize;` regularly
|
||||
- Consider `VACUUM` if database grew significantly
|
||||
|
||||
3. **Schema errors:**
|
||||
- Verify SQLite version compatibility
|
||||
- Check foreign key constraints
|
||||
|
||||
### Getting Help
|
||||
|
||||
- Check the main project README for C implementation details
|
||||
- Review nostr-rs-relay documentation for reference implementation
|
||||
- Consult Nostr NIPs for protocol specifications

# NIP-42 Authentication Implementation
|
||||
|
||||
## Overview
|
||||
|
||||
This relay implements NIP-42 (Authentication of clients to relays) providing granular authentication controls for event submission and subscription operations. The implementation supports both challenge-response authentication and per-connection state management.
|
||||
|
||||
## Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
1. **Per-Session Authentication State** (`struct per_session_data`)
|
||||
- `authenticated`: Boolean flag indicating authentication status
|
||||
- `authenticated_pubkey[65]`: Hex-encoded public key of authenticated user
|
||||
- `active_challenge[65]`: Current authentication challenge
|
||||
- `challenge_created`: Timestamp when challenge was generated
|
||||
- `challenge_expires`: Challenge expiration timestamp
|
||||
- `nip42_auth_required_events`: Whether auth is required for EVENT submission
|
||||
- `nip42_auth_required_subscriptions`: Whether auth is required for REQ operations
|
||||
- `auth_challenge_sent`: Flag indicating if challenge has been sent
|
||||
|
||||
2. **Challenge Management** (via `request_validator.c`)
|
||||
- `nostr_nip42_generate_challenge()`: Generates cryptographically secure challenges
|
||||
- `nostr_nip42_verify_auth_event()`: Validates signed authentication events
|
||||
- Challenge storage and cleanup with expiration handling
|
||||
|
||||
3. **WebSocket Protocol Integration**
|
||||
- AUTH message handling in `nostr_relay_callback()`
|
||||
- Challenge generation and transmission
|
||||
- Authentication verification and session state updates
|
||||
|
||||
## Configuration Options
|
||||
|
||||
### Event-Based Configuration
|
||||
|
||||
NIP-42 authentication is configured using kind 33334 configuration events with the following tags:
|
||||
|
||||
| Tag | Description | Default | Values |
|
||||
|-----|-------------|---------|--------|
|
||||
| `nip42_auth_required_events` | Require auth for EVENT submission | `false` | `true`/`false` |
|
||||
| `nip42_auth_required_subscriptions` | Require auth for REQ operations | `false` | `true`/`false` |
|
||||
|
||||
### Example Configuration Event
|
||||
|
||||
```json
|
||||
{
|
||||
"kind": 33334,
|
||||
"content": "C Nostr Relay Configuration",
|
||||
"tags": [
|
||||
["d", "<relay_pubkey>"],
|
||||
["nip42_auth_required_events", "true"],
|
||||
["nip42_auth_required_subscriptions", "false"],
|
||||
["relay_description", "Authenticated Nostr Relay"]
|
||||
],
|
||||
"created_at": 1640995200,
|
||||
"pubkey": "<admin_pubkey>",
|
||||
"id": "<event_id>",
|
||||
"sig": "<signature>"
|
||||
}
|
||||
```
|
||||
|
||||
## Authentication Flow
|
||||
|
||||
### 1. Challenge Generation
|
||||
|
||||
When authentication is required and client is not authenticated:
|
||||
|
||||
```
|
||||
Client -> Relay: ["EVENT", <event>] (unauthenticated)
|
||||
Relay -> Client: ["AUTH", <challenge>]
|
||||
```
|
||||
|
||||
The challenge is a 64-character hex string generated using cryptographically secure random numbers.
|
||||
|
||||
### 2. Authentication Response
|
||||
|
||||
Client creates and signs an authentication event (kind 22242):
|
||||
|
||||
```json
|
||||
{
|
||||
"kind": 22242,
|
||||
"content": "",
|
||||
"tags": [
|
||||
["relay", "ws://relay.example.com"],
|
||||
["challenge", "<challenge_from_relay>"]
|
||||
],
|
||||
"created_at": <current_timestamp>,
|
||||
"pubkey": "<client_pubkey>",
|
||||
"id": "<event_id>",
|
||||
"sig": "<signature>"
|
||||
}
|
||||
```
|
||||
|
||||
Client sends this event back to relay:
|
||||
|
||||
```
|
||||
Client -> Relay: ["AUTH", <signed_auth_event>]
|
||||
```
|
||||
|
||||
### 3. Verification and Session Update
|
||||
|
||||
The relay:
|
||||
1. Validates the authentication event signature
|
||||
2. Verifies the challenge matches the one sent
|
||||
3. Checks challenge expiration (default: 10 minutes)
|
||||
4. Updates session state with authenticated public key
|
||||
5. Sends confirmation notice
|
||||
|
||||
```
|
||||
Relay -> Client: ["NOTICE", "NIP-42 authentication successful"]
|
||||
```
|
||||
|
||||
## Granular Authentication Controls
|
||||
|
||||
### Separate Controls for Events vs Subscriptions
|
||||
|
||||
The implementation provides separate authentication requirements:
|
||||
|
||||
- **Event Submission**: Control whether clients must authenticate to publish events
|
||||
- **Subscription Access**: Control whether clients must authenticate to create subscriptions
|
||||
|
||||
This allows flexible relay policies:
|
||||
- **Public Read, Authenticated Write**: `events=true, subscriptions=false`
|
||||
- **Fully Authenticated**: `events=true, subscriptions=true`
|
||||
- **Public Access**: `events=false, subscriptions=false` (default)
|
||||
- **Authenticated Read Only**: `events=false, subscriptions=true`
|
||||
|
||||
### Per-Connection State
|
||||
|
||||
Each WebSocket connection maintains its own authentication state:
|
||||
- Authentication persists for the lifetime of the connection
|
||||
- Challenges expire after 10 minutes
|
||||
- Session cleanup on connection close
|
||||
|
||||
## Security Features
|
||||
|
||||
### Challenge Security
|
||||
- 64-character hexadecimal challenges (256 bits of entropy)
|
||||
- Cryptographically secure random generation
|
||||
- Challenge expiration to prevent replay attacks
|
||||
- One-time use challenges
|
||||
|
||||
### Event Validation
|
||||
- Complete signature verification using secp256k1
|
||||
- Event ID validation
|
||||
- Challenge-response binding verification
|
||||
- Timestamp validation with configurable tolerance
|
||||
|
||||
### Session Management
|
||||
- Thread-safe per-session state management
|
||||
- Automatic cleanup on disconnection
|
||||
- Challenge expiration handling
|
||||
|
||||
## Client Integration
|
||||
|
||||
### Using nak Client
|
||||
|
||||
```bash
|
||||
# Generate keypair
|
||||
PRIVKEY=$(nak key --gen)
|
||||
PUBKEY=$(nak key --pub $PRIVKEY)
|
||||
|
||||
# Connect and authenticate automatically
|
||||
nak event -k 1 --content "Authenticated message" --sec $PRIVKEY --relay ws://localhost:8888
|
||||
|
||||
# nak handles NIP-42 authentication automatically when required
|
||||
```
|
||||
|
||||
### Manual WebSocket Integration
|
||||
|
||||
```javascript
|
||||
const ws = new WebSocket('ws://localhost:8888');
|
||||
|
||||
ws.onmessage = (event) => {
|
||||
const message = JSON.parse(event.data);
|
||||
|
||||
if (message[0] === 'AUTH') {
|
||||
const challenge = message[1];
|
||||
|
||||
// Create auth event (kind 22242)
|
||||
const authEvent = {
|
||||
kind: 22242,
|
||||
content: "",
|
||||
tags: [
|
||||
["relay", "ws://localhost:8888"],
|
||||
["challenge", challenge]
|
||||
],
|
||||
created_at: Math.floor(Date.now() / 1000),
|
||||
pubkey: clientPubkey,
|
||||
// ... calculate id and signature
|
||||
};
|
||||
|
||||
// Send auth response
|
||||
ws.send(JSON.stringify(["AUTH", authEvent]));
|
||||
}
|
||||
};
|
||||
|
||||
// Send event (may trigger AUTH challenge)
|
||||
ws.send(JSON.stringify(["EVENT", myEvent]));
|
||||
```
|
||||
|
||||
## Administration
|
||||
|
||||
### Enabling Authentication
|
||||
|
||||
1. **Get Admin Private Key**: Extract from relay startup logs (shown once)
|
||||
2. **Create Configuration Event**: Use nak or custom tooling
|
||||
3. **Publish Configuration**: Send to relay with admin signature
|
||||
|
||||
```bash
|
||||
# Enable auth for events only
|
||||
nak event -k 33334 \
|
||||
--content "C Nostr Relay Configuration" \
|
||||
--tag "d=$RELAY_PUBKEY" \
|
||||
--tag "nip42_auth_required_events=true" \
|
||||
--tag "nip42_auth_required_subscriptions=false" \
|
||||
--sec $ADMIN_PRIVKEY \
|
||||
--relay ws://localhost:8888
|
||||
```
|
||||
|
||||
### Monitoring Authentication
|
||||
|
||||
- Check relay logs for authentication events
|
||||
- Monitor `NOTICE` messages for auth status
|
||||
- Use `get_settings.sh` script to view current configuration
|
||||
|
||||
```bash
|
||||
./get_settings.sh
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Challenge Expiration**
|
||||
- Default: 10 minutes
|
||||
- Client must respond within expiration window
|
||||
- Generate new challenge for expired attempts
|
||||
|
||||
2. **Signature Verification Failures**
|
||||
- Verify event structure matches NIP-42 specification
|
||||
- Check challenge value matches exactly
|
||||
- Ensure proper secp256k1 signature generation
|
||||
|
||||
3. **Configuration Not Applied**
|
||||
- Verify admin private key is correct
|
||||
- Check configuration event signature
|
||||
- Ensure relay pubkey in 'd' tag matches relay
|
||||
|
||||
### Debug Commands
|
||||
|
||||
```bash
|
||||
# Check supported NIPs
|
||||
curl -H "Accept: application/nostr+json" http://localhost:8888 | jq .supported_nips
|
||||
|
||||
# View current configuration
|
||||
nak req -k 33334 ws://localhost:8888 | jq .
|
||||
|
||||
# Test authentication flow
|
||||
./tests/42_nip_test.sh
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- Challenge generation: ~1ms overhead per unauthenticated connection
|
||||
- Authentication verification: ~2-5ms per auth event
|
||||
- Memory overhead: ~200 bytes per connection for auth state
|
||||
- Database impact: Configuration events cached, minimal query overhead
|
||||
|
||||
## Integration with Other NIPs
|
||||
|
||||
### NIP-01 (Basic Protocol)
|
||||
- AUTH messages integrated into standard WebSocket flow
|
||||
- Compatible with existing EVENT/REQ/CLOSE message handling
|
||||
|
||||
### NIP-11 (Relay Information)
|
||||
- NIP-42 advertised in `supported_nips` array
|
||||
- Authentication requirements reflected in relay metadata
|
||||
|
||||
### NIP-20 (Command Results)
|
||||
- OK responses include authentication-related error messages
|
||||
- NOTICE messages provide authentication status updates
|
||||
|
||||
## Future Extensions
|
||||
|
||||
### Potential Enhancements
|
||||
- Role-based authentication (admin, user, read-only)
|
||||
- Time-based access controls
|
||||
- Rate limiting based on authentication status
|
||||
- Integration with external authentication providers
|
||||
|
||||
### Configuration Extensions
|
||||
- Per-kind authentication requirements
|
||||
- Whitelist/blacklist integration
|
||||
- Custom challenge expiration times
|
||||
- Authentication logging and metrics

# C-Relay Administrator API Implementation Plan
|
||||
|
||||
## Problem Analysis
|
||||
|
||||
### Current Issues Identified:
|
||||
|
||||
1. **Schema Mismatch**: Storage system (config.c) vs Validation system (request_validator.c) use different column names and values
|
||||
2. **Missing API Endpoint**: No way to clear auth_rules table for testing
|
||||
3. **Configuration Gap**: Auth rules enforcement may not be properly enabled
|
||||
4. **Documentation Gap**: Admin API commands not documented
|
||||
|
||||
### Root Cause: Auth Rules Schema Inconsistency
|
||||
|
||||
**Current Schema (sql_schema.h lines 140-150):**
|
||||
```sql
|
||||
CREATE TABLE auth_rules (
|
||||
rule_type TEXT CHECK (rule_type IN ('whitelist', 'blacklist')),
|
||||
pattern_type TEXT CHECK (pattern_type IN ('pubkey', 'hash')),
|
||||
pattern_value TEXT,
|
||||
action TEXT CHECK (action IN ('allow', 'deny')),
|
||||
active INTEGER DEFAULT 1
|
||||
);
|
||||
```
|
||||
|
||||
**Storage Implementation (config.c):**
|
||||
- Stores: `rule_type='blacklist'`, `pattern_type='pubkey'`, `pattern_value='hex'`, `action='allow'`
|
||||
|
||||
**Validation Implementation (request_validator.c):**
|
||||
- Queries: `rule_type='pubkey_blacklist'`, `rule_target='hex'`, `operation='event'`, `enabled=1`
|
||||
|
||||
**MISMATCH**: Validator looks for non-existent columns and wrong rule_type values!
|
||||
|
||||
## Proposed Solution Architecture
|
||||
|
||||
### Phase 1: API Documentation & Standardization
|
||||
|
||||
#### Admin API Commands (via WebSocket with admin private key)
|
||||
|
||||
**Kind 23456: Unified Admin API (Ephemeral)**
|
||||
- Configuration management: Update relay settings, limits, authentication policies
|
||||
- Auth rules: Add/remove/query whitelist/blacklist rules
|
||||
- System commands: clear rules, status, cache management
|
||||
- **Unified Format**: All commands use NIP-44 encrypted content with `["p", "relay_pubkey"]` tags
|
||||
- **Command Types**:
|
||||
- Configuration: `["config_key", "config_value"]`
|
||||
- Auth rules: `["rule_type", "pattern_type", "pattern_value"]`
|
||||
- Queries: `["auth_query", "filter"]` or `["system_command", "command_name"]`
|
||||
- **Security**: All admin commands use NIP-44 encryption for privacy and security
|
||||
|
||||
#### Configuration Commands (using Kind 23456)
|
||||
|
||||
1. **Update Configuration**:
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [["p", "relay_pubkey"]]
|
||||
}
|
||||
```
|
||||
*Encrypted content contains:* `["relay_description", "My Relay"]`
|
||||
|
||||
2. **Query System Status**:
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [["p", "relay_pubkey"]]
|
||||
}
|
||||
```
|
||||
*Encrypted content contains:* `["system_command", "system_status"]`
|
||||
|
||||
#### Auth Rules and System Commands (using Kind 23456)
|
||||
|
||||
1. **Clear All Auth Rules**:
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [["p", "relay_pubkey"]]
|
||||
}
|
||||
```
|
||||
*Encrypted content contains:* `["system_command", "clear_all_auth_rules"]`
|
||||
|
||||
2. **Query All Auth Rules**:
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [["p", "relay_pubkey"]]
|
||||
}
|
||||
```
|
||||
*Encrypted content contains:* `["auth_query", "all"]`
|
||||
|
||||
3. **Add Blacklist Rule**:
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [["p", "relay_pubkey"]]
|
||||
}
|
||||
```
|
||||
*Encrypted content contains:* `["blacklist", "pubkey", "deadbeef1234abcd..."]`
|
||||
|
||||
### Phase 2: Auth Rules Schema Alignment
|
||||
|
||||
#### Option A: Fix Validator to Match Schema (RECOMMENDED)
|
||||
|
||||
**Update request_validator.c:**
|
||||
```sql
|
||||
-- OLD (broken):
|
||||
WHERE rule_type = 'pubkey_blacklist' AND rule_target = ? AND operation = ? AND enabled = 1
|
||||
|
||||
-- NEW (correct):
|
||||
WHERE rule_type = 'blacklist' AND pattern_type = 'pubkey' AND pattern_value = ? AND active = 1
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Matches actual database schema
|
||||
- Simpler rule_type values ('blacklist' vs 'pubkey_blacklist')
|
||||
- Uses existing columns (pattern_value vs rule_target)
|
||||
- Consistent with storage implementation
|
||||
|
||||
#### Option B: Update Schema to Match Validator (NOT RECOMMENDED)
|
||||
|
||||
Would require changing schema, migration scripts, and storage logic.
|
||||
|
||||
### Phase 3: Implementation Priority
|
||||
|
||||
#### High Priority (Critical for blacklist functionality):
|
||||
1. Fix request_validator.c schema mismatch
|
||||
2. Ensure auth_required configuration is enabled
|
||||
3. Update tests to use unified ephemeral event kind (23456)
|
||||
4. Test blacklist enforcement
|
||||
|
||||
#### Medium Priority (Enhanced Admin Features):
|
||||
1. **Implement NIP-44 Encryption Support**:
|
||||
- Detect NIP-44 encrypted content for Kind 23456 events
|
||||
- Parse `encrypted_tags` field from content JSON
|
||||
- Decrypt using admin privkey and relay pubkey
|
||||
- Process decrypted tags as normal commands
|
||||
2. Add clear_all_auth_rules system command
|
||||
3. Add auth rule query functionality (both standard and encrypted modes)
|
||||
4. Add configuration discovery (list available config keys)
|
||||
5. Enhanced error reporting in admin API
|
||||
6. Conflict resolution (same pubkey in whitelist + blacklist)
|
||||
|
||||
#### Security Priority (NIP-44 Implementation):
|
||||
1. **Encryption Detection Logic**: Check for empty tags + encrypted_tags field
|
||||
2. **Key Pair Management**: Use admin private key + relay public key for NIP-44
|
||||
3. **Backward Compatibility**: Support both standard and encrypted modes
|
||||
4. **Error Handling**: Graceful fallback if decryption fails
|
||||
5. **Performance**: Cache decrypted results to avoid repeated decryption
|
||||
|
||||
#### Low Priority (Documentation & Polish):
|
||||
1. Complete README.md API documentation
|
||||
2. Example usage scripts
|
||||
3. Admin client tools
|
||||
|
||||
### Phase 4: Expected API Structure
|
||||
|
||||
#### README.md Documentation Format:
|
||||
|
||||
```markdown
|
||||
# C-Relay Administrator API
|
||||
|
||||
## Authentication
|
||||
All admin commands require signing with the admin private key generated during first startup.
|
||||
|
||||
## Unified Admin API (Kind 23456 - Ephemeral)
|
||||
Update relay configuration parameters or query available settings.
|
||||
|
||||
**Configuration Update Event:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "base64_nip44_encrypted_command_array",
|
||||
"tags": [["p", "relay_pubkey"]]
|
||||
}
|
||||
```
|
||||
*Encrypted content contains:* `["relay_description", "My Relay Description"]`
|
||||
|
||||
**Auth Rules Management:**
|
||||
|
||||
**Add Rule Event:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"action\":\"add\",\"description\":\"Block malicious user\"}",
|
||||
"tags": [
|
||||
["blacklist", "pubkey", "deadbeef1234..."]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Remove Rule Event:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"action\":\"remove\",\"description\":\"Unblock user\"}",
|
||||
"tags": [
|
||||
["blacklist", "pubkey", "deadbeef1234..."]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Query All Auth Rules:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"query\":\"list_auth_rules\",\"description\":\"Get all rules\"}",
|
||||
"tags": [
|
||||
["auth_query", "all"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Query Whitelist Rules Only:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"query\":\"list_auth_rules\",\"description\":\"Get whitelist\"}",
|
||||
"tags": [
|
||||
["auth_query", "whitelist"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Check Specific Pattern:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"query\":\"check_pattern\",\"description\":\"Check if pattern exists\"}",
|
||||
"tags": [
|
||||
["auth_query", "pattern", "deadbeef1234..."]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## System Management (Kind 23456 - Ephemeral)
|
||||
System administration commands using the same kind as auth rules.
|
||||
|
||||
**Clear All Auth Rules:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"action\":\"clear_all\",\"description\":\"Clear all auth rules\"}",
|
||||
"tags": [
|
||||
["system_command", "clear_all_auth_rules"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**System Status:**
|
||||
```json
|
||||
{
|
||||
"kind": 23456,
|
||||
"content": "{\"action\":\"system_status\",\"description\":\"Get system status\"}",
|
||||
"tags": [
|
||||
["system_command", "system_status"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Response Format
|
||||
All admin commands return JSON responses via WebSocket:
|
||||
|
||||
**Success Response:**
|
||||
```json
|
||||
["OK", "event_id", true, "success_message"]
|
||||
```
|
||||
|
||||
**Error Response:**
|
||||
```json
|
||||
["OK", "event_id", false, "error_message"]
|
||||
```
|
||||
|
||||
## Configuration Keys
|
||||
- `relay_description`: Relay description text
|
||||
- `relay_contact`: Contact information
|
||||
- `auth_enabled`: Enable authentication system
|
||||
- `max_connections`: Maximum concurrent connections
|
||||
- `pow_min_difficulty`: Minimum proof-of-work difficulty
|
||||
- ... (full list of config keys)
|
||||
|
||||
## Examples
|
||||
|
||||
### Enable Authentication & Add Blacklist
|
||||
```bash
|
||||
# 1. Enable auth system
|
||||
nak event -k 23456 --content "base64_nip44_encrypted_command" \
|
||||
-t "auth_enabled=true" \
|
||||
--sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
|
||||
|
||||
# 2. Add user to blacklist
|
||||
nak event -k 23456 --content '{"action":"add","description":"Spam user"}' \
|
||||
-t "blacklist=pubkey;$SPAM_USER_PUBKEY" \
|
||||
--sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
|
||||
|
||||
# 3. Query all auth rules
|
||||
nak event -k 23456 --content '{"query":"list_auth_rules","description":"Get all rules"}' \
|
||||
-t "auth_query=all" \
|
||||
--sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
|
||||
|
||||
# 4. Clear all rules for testing
|
||||
nak event -k 23456 --content '{"action":"clear_all","description":"Clear all rules"}' \
|
||||
-t "system_command=clear_all_auth_rules" \
|
||||
--sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
|
||||
```
|
||||
|
||||
## Expected Response Formats

|
||||
"tags": [["response_type", "auth_rules_list"], ["query_type", "all"]]
|
||||
}]
|
||||
```
|
||||
|
||||
### Pattern Check Response

|
||||
"tags": [["response_type", "pattern_check"], ["pattern", "deadbeef..."]]
|
||||
}]
|
||||
```
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
1. **Document API** (this file) ✅
|
||||
2. **Update to ephemeral event kinds** ✅
|
||||
3. **Fix request_validator.c** schema mismatch
|
||||
4. **Update tests** to use unified Kind 23456
|
||||
5. **Add auth rule query functionality**
|
||||
6. **Add configuration discovery feature**
|
||||
7. **Test blacklist functionality**
|
||||
8. **Add remaining system commands**
|
||||
|
||||
## Testing Plan
|
||||
|
||||
1. Fix schema mismatch and test basic blacklist
|
||||
2. Add clear_auth_rules and test table cleanup
|
||||
3. Test whitelist/blacklist conflict scenarios
|
||||
4. Test all admin API commands end-to-end
|
||||
5. Update integration tests
|
||||
|
||||
This plan addresses the immediate blacklist issue while establishing a comprehensive admin API framework for future expansion.

## NIP-44 Encryption Implementation Details
|
||||
|
||||
### Server-Side Detection Logic
|
||||
```c
|
||||
// In admin event processing function
|
||||
bool is_encrypted_command(struct nostr_event *event) {
|
||||
// Check if Kind 23456 with NIP-44 encrypted content
|
||||
if (event->kind == 23456 &&
|
||||
event->tags_count == 0) {
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
cJSON *decrypt_admin_tags(struct nostr_event *event) {
|
||||
cJSON *content_json = cJSON_Parse(event->content);
|
||||
if (!content_json) return NULL;
|
||||
|
||||
cJSON *encrypted_tags = cJSON_GetObjectItem(content_json, "encrypted_tags");
|
||||
if (!encrypted_tags) {
|
||||
cJSON_Delete(content_json);
|
||||
return NULL;
|
||||
}
|
||||
|
||||
// Decrypt using NIP-44 with admin pubkey and relay privkey
|
||||
char *decrypted = nip44_decrypt(
|
||||
cJSON_GetStringValue(encrypted_tags),
|
||||
admin_pubkey, // Shared secret with admin
|
||||
relay_private_key // Our private key
|
||||
);
|
||||
|
||||
cJSON *decrypted_tags = cJSON_Parse(decrypted);
|
||||
free(decrypted);
|
||||
cJSON_Delete(content_json);
|
||||
|
||||
return decrypted_tags; // Returns tag array: [["key1", "val1"], ["key2", "val2"]]
|
||||
}
|
||||
```
|
||||
|
||||
### Admin Event Processing Flow
|
||||
1. **Receive Event**: Kind 23456 with admin signature
|
||||
2. **Check Mode**: Empty tags = encrypted, populated tags = standard
|
||||
3. **Decrypt if Needed**: Extract and decrypt `encrypted_tags` from content
|
||||
4. **Process Commands**: Use decrypted/standard tags for command processing
|
||||
5. **Execute**: Same logic for both modes after tag extraction
|
||||
6. **Respond**: Standard response format (optionally encrypt response)
|
||||
|
||||
### Security Benefits
|
||||
- **Command Privacy**: Admin operations invisible in event tags
|
||||
- **Replay Protection**: NIP-44 includes timestamp/randomness
|
||||
- **Key Management**: Uses existing admin/relay key pair
|
||||
- **Backward Compatible**: Standard mode still works
|
||||
- **Performance**: Only decrypt when needed (empty tags detection)
|
||||
|
||||
### NIP-44 Library Integration
|
||||
The relay will need to integrate a NIP-44 encryption/decryption library:
|
||||
|
||||
```c
|
||||
// Required NIP-44 functions
|
||||
char* nip44_encrypt(const char* plaintext, const char* sender_privkey, const char* recipient_pubkey);
|
||||
char* nip44_decrypt(const char* ciphertext, const char* recipient_privkey, const char* sender_pubkey);
|
||||
```
|
||||
|
||||
### Implementation Priority (Updated)
|
||||
|
||||
#### Phase 1: Core Infrastructure (Complete)
|
||||
- [x] Event-based admin authentication system
|
||||
- [x] Kind 23456 (Unified Admin API) processing
|
||||
- [x] Basic configuration parameter updates
|
||||
- [x] Auth rule add/remove/clear functionality
|
||||
- [x] Updated to ephemeral event kinds
|
||||
- [x] Designed NIP-44 encryption support
|
||||
|
||||
#### Phase 2: NIP-44 Encryption Support (Next Priority)
|
||||
- [ ] **Add NIP-44 library dependency** to project
|
||||
- [ ] **Implement encryption detection logic** (`is_encrypted_command()`)
|
||||
- [ ] **Add decrypt_admin_tags() function** with NIP-44 support
|
||||
- [ ] **Update admin command processing** to handle both modes
|
||||
- [ ] **Test encrypted admin commands** end-to-end
|
||||
|
||||
#### Phase 3: Enhanced Features
|
||||
- [ ] **Auth rule query functionality** (both standard and encrypted modes)
|
||||
- [ ] **Configuration discovery API** (list available config keys)
|
||||
- [ ] **Enhanced error messages** with encryption status
|
||||
- [ ] **Performance optimization** (caching, async decrypt)
|
||||
|
||||
#### Phase 4: Schema Fixes (Critical)
|
||||
- [ ] **Fix request_validator.c** schema mismatch
|
||||
- [ ] **Enable blacklist enforcement** with encrypted commands
|
||||
- [ ] **Update tests** to use both standard and encrypted modes
|
||||
|
||||
This enhanced admin API provides enterprise-grade security while maintaining ease of use for basic operations.

# Database Configuration Schema Design
|
||||
|
||||
## Overview
|
||||
This document outlines the database configuration schema additions for the C Nostr Relay startup config file system. The design follows the Ginxsom admin system approach with signed Nostr events and database storage.
|
||||
|
||||
## Schema Version Update
|
||||
- Current Version: 2
|
||||
- Target Version: 3
|
||||
- Update: Add server configuration management tables
|
||||
|
||||
## Core Configuration Tables
|
||||
|
||||
### 1. `server_config` Table
|
||||
|
||||
```sql
|
||||
-- Server configuration table - core configuration storage
|
||||
CREATE TABLE server_config (
|
||||
key TEXT PRIMARY KEY, -- Configuration key (unique identifier)
|
||||
value TEXT NOT NULL, -- Configuration value (stored as string)
|
||||
description TEXT, -- Human-readable description
|
||||
config_type TEXT DEFAULT 'user' CHECK (config_type IN ('system', 'user', 'runtime')),
|
||||
data_type TEXT DEFAULT 'string' CHECK (data_type IN ('string', 'integer', 'boolean', 'json')),
|
||||
validation_rules TEXT, -- JSON validation rules (optional)
|
||||
is_sensitive INTEGER DEFAULT 0, -- 1 if value should be masked in logs
|
||||
requires_restart INTEGER DEFAULT 0, -- 1 if change requires server restart
|
||||
created_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
|
||||
updated_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now'))
|
||||
);
|
||||
```
|
||||
|
||||
**Configuration Types:**
|
||||
- `system`: Core system settings (admin keys, security)
|
||||
- `user`: User-configurable settings (relay info, features)
|
||||
- `runtime`: Dynamic runtime values (statistics, cache)
|
||||
|
||||
**Data Types:**
|
||||
- `string`: Text values
|
||||
- `integer`: Numeric values
|
||||
- `boolean`: True/false values (stored as "true"/"false")
|
||||
- `json`: JSON object/array values
|
||||
|
||||
### 2. `config_history` Table
|
||||
|
||||
```sql
|
||||
-- Configuration change history table
|
||||
CREATE TABLE config_history (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
config_key TEXT NOT NULL, -- Key that was changed
|
||||
old_value TEXT, -- Previous value (NULL for new keys)
|
||||
new_value TEXT NOT NULL, -- New value
|
||||
changed_by TEXT DEFAULT 'system', -- Who made the change (system/admin/user)
|
||||
change_reason TEXT, -- Optional reason for change
|
||||
changed_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
|
||||
FOREIGN KEY (config_key) REFERENCES server_config(key)
|
||||
);
|
||||
```
|
||||
|
||||
### 3. `config_validation_log` Table
|
||||
|
||||
```sql
|
||||
-- Configuration validation errors log
|
||||
CREATE TABLE config_validation_log (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
config_key TEXT NOT NULL,
|
||||
attempted_value TEXT,
|
||||
validation_error TEXT NOT NULL,
|
||||
error_source TEXT DEFAULT 'validation', -- validation/parsing/constraint
|
||||
attempted_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now'))
|
||||
);
|
||||
```
|
||||
|
||||
### 4. Configuration File Cache Table
|
||||
|
||||
```sql
|
||||
-- Cache for file-based configuration events
|
||||
CREATE TABLE config_file_cache (
|
||||
file_path TEXT PRIMARY KEY, -- Full path to config file
|
||||
file_hash TEXT NOT NULL, -- SHA256 hash of file content
|
||||
event_id TEXT, -- Nostr event ID from file
|
||||
event_pubkey TEXT, -- Admin pubkey that signed event
|
||||
loaded_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
|
||||
validation_status TEXT CHECK (validation_status IN ('valid', 'invalid', 'unverified')),
|
||||
validation_error TEXT -- Error details if invalid
|
||||
);
|
||||
```
|
||||
|
||||
## Indexes and Performance
|
||||
|
||||
```sql
|
||||
-- Performance indexes for configuration tables
|
||||
CREATE INDEX idx_server_config_type ON server_config(config_type);
|
||||
CREATE INDEX idx_server_config_updated ON server_config(updated_at DESC);
|
||||
CREATE INDEX idx_config_history_key ON config_history(config_key);
|
||||
CREATE INDEX idx_config_history_time ON config_history(changed_at DESC);
|
||||
CREATE INDEX idx_config_validation_key ON config_validation_log(config_key);
|
||||
CREATE INDEX idx_config_validation_time ON config_validation_log(attempted_at DESC);
|
||||
```
|
||||
|
||||
## Triggers
|
||||
|
||||
### Update Timestamp Trigger
|
||||
|
||||
```sql
|
||||
-- Trigger to update timestamp on configuration changes
|
||||

|
||||
BEGIN
|
||||
UPDATE server_config SET updated_at = strftime('%s', 'now') WHERE key = NEW.key;
|
||||
END;
|
||||
```
|
||||
|
||||
### Configuration History Trigger
|
||||
|
||||
```sql
|
||||
-- Trigger to log configuration changes to history
|
||||
CREATE TRIGGER log_config_changes
|
||||
AFTER UPDATE ON server_config
|
||||
WHEN OLD.value != NEW.value
|
||||
BEGIN
|
||||
INSERT INTO config_history (config_key, old_value, new_value, changed_by, change_reason)
|

|
||||
```
|
||||
|
||||
## Configuration Views
|
||||
|
||||
### Active Configuration View
|
||||
|
||||
```sql
|
||||
CREATE VIEW active_config AS
|
||||
SELECT
|
||||
key,
|
||||
value,
|
||||
description,
|
||||
config_type,
|
||||
data_type,
|
||||
requires_restart,
|
||||
updated_at
|
||||
FROM server_config
|
||||
WHERE config_type IN ('system', 'user')
|
||||
ORDER BY config_type, key;
|
||||
```
|
||||
|
||||
### Runtime Statistics View
|
||||
|
||||
```sql
|
||||
CREATE VIEW runtime_stats AS
|
||||
SELECT
|
||||
key,
|
||||
value,
|
||||
description,
|
||||
updated_at
|
||||
FROM server_config
|
||||
WHERE config_type = 'runtime'
|
||||
ORDER BY key;
|
||||
```
|
||||
|
||||
### Configuration Change Summary
|
||||
|
||||
```sql
|
||||
CREATE VIEW recent_config_changes AS
|
||||
SELECT
|
||||
ch.config_key,
|
||||
sc.description,
|
||||
ch.old_value,
|
||||
ch.new_value,
|
||||
ch.changed_by,
|
||||
ch.change_reason,
|
||||
ch.changed_at
|
||||
FROM config_history ch
|
||||
JOIN server_config sc ON ch.config_key = sc.key
|
||||
ORDER BY ch.changed_at DESC
|
||||
LIMIT 50;
|
||||
```
|
||||
|
||||
## Validation Rules Format
|
||||
|
||||
Configuration validation rules are stored as JSON strings in the `validation_rules` column:
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "integer",
|
||||
"min": 1,
|
||||
"max": 65535,
|
||||
"required": true
|
||||
}
|
||||
```
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "string",
|
||||
"pattern": "^[0-9a-fA-F]{64}$",
|
||||
"required": false,
|
||||
"description": "64-character hex string"
|
||||
}
|
||||
```
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "boolean",
|
||||
"required": true
|
||||
}
|
||||
```
|
||||
|
||||
## Migration Strategy
|
||||
|
||||
1. **Phase 1**: Add configuration tables to existing schema
|
||||
2. **Phase 2**: Populate with current hardcoded values
|
||||
3. **Phase 3**: Update application code to read from database
|
||||
4. **Phase 4**: Add file-based configuration loading
|
||||
5. **Phase 5**: Remove hardcoded defaults and environment variable fallbacks
|
||||
|
||||
## Integration Points
|
||||
|
||||
- **Startup**: Load configuration from file → database → apply to application
|
||||
- **Runtime**: Read configuration values from database cache
|
||||
- **Updates**: Write changes to database → optionally update file
|
||||
- **Validation**: Validate all configuration changes before applying
|
||||
- **History**: Track all configuration changes for audit purposes

## Overview
|
||||
|
||||
The C Nostr Relay uses a revolutionary **event-based configuration system** where all settings are stored as kind 33334 Nostr events in the database. This provides several advantages:
|
||||
|
||||
### Benefits
|
||||
- **Real-time updates**: Configuration changes applied instantly without restart
|
||||
- **Cryptographic security**: All changes must be cryptographically signed by admin
|
||||
- **Audit trail**: Complete history of all configuration changes
|
||||
- **Version control**: Each configuration change is timestamped and signed
|
||||
- **Zero files**: No configuration files to manage, backup, or version control
|
||||
|
||||
### How It Works
|
||||
1. **Admin keypair**: Generated on first startup, used to sign configuration events
|
||||
2. **Configuration events**: Kind 33334 Nostr events with relay settings in tags
|
||||
3. **Real-time processing**: New configuration events processed via WebSocket
|
||||
4. **Immediate application**: Changes applied to running system without restart
|
||||
|
||||
## Configuration Events
|
||||
|
||||
### Event Structure
|
||||
|
||||
Configuration events follow the standard Nostr event format with kind 33334:
|
||||
|
||||
```json
|
||||
{
|
||||
"id": "event_id_computed_from_content",
|
||||
"kind": 33334,
|
||||
"pubkey": "admin_public_key_hex",
|
||||
"created_at": 1699123456,
|
||||
"content": "C Nostr Relay Configuration",
|
||||
"tags": [
|
||||
["d", "relay_public_key_hex"],
|
||||
["relay_description", "My Nostr Relay"],
|
||||
["max_subscriptions_per_client", "25"],
|
||||
["pow_min_difficulty", "16"]
|
||||
],
|
||||
"sig": "signature_computed_with_admin_private_key"
|
||||
}
|
||||
```
|
||||
|
||||
### Required Tags
|
||||
- **`d` tag**: Must contain the relay's public key (identifies which relay this config is for)
|
||||
|
||||
### Event Properties
|
||||
- **Kind**: Must be exactly `33334`
|
||||
- **Content**: Should be descriptive (e.g., "C Nostr Relay Configuration")
|
||||
- **Pubkey**: Must be the admin public key generated at first startup
|
||||
- **Signature**: Must be valid signature from admin private key
|
||||
|
||||

```
|
||||
|
||||
### Private/Corporate Relay
|
||||
```json
|
||||
{
|
||||
"kind": 33334,
|
||||
"content": "Corporate Internal Relay",
|
||||
"tags": [
|
||||
["d", "relay_pubkey_here"],
|

|
||||
["pow_mode", "disabled"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Admin Key Management
|
||||
|
||||
#### Secure Storage
|
||||
```bash
|
||||
# Store admin private key securely
|
||||
echo "ADMIN_PRIVKEY=your_admin_private_key_here" > .env
|
||||
chmod 600 .env
|
||||
|
||||
# Or use a password manager
|
||||
# Never store in version control
|
||||
echo ".env" >> .gitignore
|
||||
```
|
||||
|
||||
#### Key Rotation
|
||||
Currently, admin key rotation requires:
|
||||
1. Stopping the relay
|
||||
2. Removing the database (loses all events)
|
||||
3. Restarting (generates new keys)
|
||||
|
||||
Future versions will support admin key rotation while preserving events.
|
||||
|
||||
### Event Validation
|
||||
|
||||
The relay performs comprehensive validation on configuration events:
|
||||
|
||||
#### Cryptographic Validation
|
||||
- **Signature verification**: Uses `nostr_verify_event_signature()`
|
||||
- **Event structure**: Validates JSON structure with `nostr_validate_event_structure()`
|
||||
- **Admin authorization**: Ensures events are signed by the authorized admin pubkey
|
||||
|
||||
#### Content Validation
|
||||
- **Parameter bounds checking**: Validates numeric ranges
|
||||
- **String length limits**: Enforces maximum lengths
|
||||
- **Enum validation**: Validates allowed values for mode parameters
|
||||
|
||||
### Network Security
|
||||
|
||||
#### Access Control
|
||||
```bash
|
||||
# Limit access with firewall
|
||||
sudo ufw allow from 192.168.1.0/24 to any port 8888
|
||||
|
||||
# Or use specific IPs
|
||||
sudo ufw allow from 203.0.113.10 to any port 8888
|
||||
```
|
||||
|
||||
#### TLS/SSL Termination
|
||||
```nginx
|
||||
# nginx configuration for HTTPS termination
|
||||
server {
|
||||
listen 443 ssl;
|
||||
server_name relay.example.com;
|
||||
|
||||
ssl_certificate /path/to/cert.pem;
|
||||
ssl_certificate_key /path/to/key.pem;
|
||||
|
||||
location / {
|
||||
proxy_pass http://127.0.0.1:8888;
|
||||
proxy_http_version 1.1;
|
||||
proxy_set_header Upgrade $http_upgrade;
|
||||
proxy_set_header Connection "Upgrade";
|
||||
proxy_set_header Host $host;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Configuration Not Applied
|
||||
|
||||
#### Check Event Signature
|
||||
```javascript
|
||||
// Verify event signature with nostrtool or similar
|
||||
const event = { /* your configuration event */ };
|
||||
const isValid = nostrTools.verifySignature(event);
|
||||
```
|
||||
|
||||
#### Verify Admin Pubkey
|
||||
```bash
|
||||
# Check current admin pubkey in database
|
||||
sqlite3 relay.nrdb "SELECT DISTINCT pubkey FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
|
||||
|
||||
# Compare with expected admin pubkey from first startup
|
||||
grep "Admin Public Key" relay.log
|
||||
```
|
||||
|
||||
#### Check Event Structure
|
||||
```bash
|
||||
# View the exact event stored in database
|
||||
sqlite3 relay.nrdb "SELECT json_pretty(json_object(
|
||||
'kind', kind,
|
||||
'pubkey', pubkey,
|
||||
'created_at', created_at,
|
||||
'content', content,
|
||||
'tags', json(tags),
|
||||
'sig', sig
|
||||
)) FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
|
||||
```
|
||||
|
||||
### Configuration Validation Errors
|
||||
|
||||
#### Invalid Parameter Values
|
||||
```bash
|
||||
# Check relay logs for validation errors
|
||||
journalctl -u c-relay | grep "Configuration.*invalid\|Invalid.*configuration"
|
||||
|
||||
# Common issues:
|
||||
# - Numeric values outside valid ranges
|
||||
# - Invalid enum values (e.g., pow_mode)
|
||||
# - String values exceeding length limits
|
||||
```
|
||||
|
||||
#### Missing Required Tags
|
||||
```bash
|
||||
# Ensure 'd' tag is present with relay pubkey
|
||||
sqlite3 relay.nrdb "SELECT tags FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;" | grep '"d"'
|
||||
```
|
||||
|
||||
### Performance Impact
|
||||
|
||||
#### Monitor Configuration Changes
|
||||
```bash
|
||||
# Track configuration update frequency
|
||||
sqlite3 relay.nrdb "SELECT datetime(created_at, 'unixepoch') as date,
|
||||
COUNT(*) as config_updates
|
||||
FROM events WHERE kind = 33334
|
||||
GROUP BY date(created_at, 'unixepoch')
|
||||
ORDER BY date DESC;"
|
||||
```
|
||||
|
||||
#### Resource Usage After Changes
|
||||
```bash
|
||||
# Monitor system resources after configuration updates
|
||||
top -p $(pgrep c_relay)
|
||||
|
||||
# Check for memory leaks
|
||||
ps aux | grep c_relay | awk '{print $6}' # RSS memory
|
||||
```
|
||||
|
||||
### Emergency Recovery
|
||||
|
||||
#### Reset to Default Configuration
|
||||
If configuration becomes corrupted or causes issues:
|
||||
|
||||
```bash
|
||||
# Create emergency configuration event
|
||||
nostrtool event \
|
||||
--kind 33334 \
|
||||
--content "Emergency Reset Configuration" \
|
||||
--tag d YOUR_RELAY_PUBKEY \
|
||||
--tag max_subscriptions_per_client 25 \
|
||||
--tag max_total_subscriptions 5000 \
|
||||
--tag pow_mode optional \
|
||||
--tag pow_min_difficulty 0 \
|
||||
--private-key YOUR_ADMIN_PRIVKEY \
|
||||
| nostrtool send ws://localhost:8888
|
||||
```
|
||||
|
||||
#### Database Recovery
|
||||
```bash
|
||||
# If database is corrupted, backup and recreate
|
||||
cp relay.nrdb relay.nrdb.backup
|
||||
rm relay.nrdb*
|
||||
./build/c_relay_x86 # Creates fresh database with new keys
|
||||
```

const char* relay_pubkey_hex);
|
||||
|
||||
#endif /* DEFAULT_CONFIG_EVENT_H */
|
||||
```
|
||||
|
||||
## Usage Notes
|
||||
|
||||
1. **Isolation**: These default values are completely isolated from the rest of the program
|
||||
2. **Single Access Point**: Only accessed during `create_default_config_event()`
|
||||
3. **Runtime Keys**: Relay keys are added at runtime, not stored as defaults
|
||||
4. **No Direct Access**: Other parts of the program should never include this header directly
|
||||
5. **Clean Separation**: Keeps default configuration separate from configuration logic
|
||||
|
||||
## Function Implementation
|
||||
|
||||
The `create_default_config_event()` function will:
|
||||
|
||||
1. Create a new cJSON event object with kind 33334
|
||||
2. Add all default configuration values as tags
|
||||
3. Add runtime-generated relay keys as tags
|
||||
4. Use `nostr_core_lib` to sign the event with admin private key
|
||||
5. Return the complete signed event ready for database storage
|
||||
|
||||
This approach ensures clean separation between default values and the configuration system logic.

## Deployment Overview
|
||||
|
||||
The C Nostr Relay's event-based configuration system simplifies deployment:
|
||||
|
||||
### Key Deployment Benefits
|
||||
- **Zero Configuration**: No config files to manage or transfer
|
||||
- **Self-Contained**: Single binary + auto-generated database
|
||||
- **Portable**: Database contains all relay state and configuration
|
||||
- **Secure**: Admin keys generated locally, never transmitted
|
||||
- **Scalable**: Efficient SQLite backend with WAL mode
|
||||
|
||||
### Deployment Requirements
|
||||
- **CPU**: 1 vCPU minimum, 2+ recommended
|
||||
- **RAM**: 512MB minimum, 2GB+ recommended
|
||||
- **Storage**: 100MB for binary + database growth (varies by usage)
|
||||
- **Network**: Port 8888 (configurable via events)
|
||||
- **OS**: Linux (recommended), macOS, Windows (WSL)
|
||||
|
||||
## Production Deployment
|
||||
|
||||
### Server Preparation
|
||||
|
||||
#### System Updates
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo apt update && sudo apt upgrade -y
|
||||
|
||||
# CentOS/RHEL
|
||||
sudo yum update -y
|
||||
|
||||
# Install required packages
|
||||
sudo apt install -y build-essential git sqlite3 libsqlite3-dev \
|
||||
libwebsockets-dev libssl-dev libsecp256k1-dev libcurl4-openssl-dev \
|
||||
zlib1g-dev systemd
|
||||
```
|
||||
|
||||
#### User and Directory Setup
|
||||
```bash
|
||||
# Create dedicated system user
|
||||
sudo useradd --system --home-dir /opt/c-relay --shell /bin/false c-relay
|
||||
|
||||
# Create application directory
|
||||
sudo mkdir -p /opt/c-relay
|
||||
sudo chown c-relay:c-relay /opt/c-relay
|
||||
```
|
||||
|
||||
### Build and Installation
|
||||
|
||||
#### Automated Installation (Recommended)
|
||||
```bash
|
||||
# Clone repository
|
||||
git clone https://github.com/your-org/c-relay.git
|
||||
cd c-relay
|
||||
git submodule update --init --recursive
|
||||
|
||||
# Build
|
||||
make clean && make
|
||||
|
||||
# Install as systemd service
|
||||
sudo systemd/install-service.sh
|
||||
```
|
||||
|
||||
#### Manual Installation
|
||||
```bash
|
||||
# Build relay
|
||||
make clean && make
|
||||
|
||||
# Install binary
|
||||
sudo cp build/c_relay_x86 /opt/c-relay/
|
||||
sudo chown c-relay:c-relay /opt/c-relay/c_relay_x86
|
||||
sudo chmod +x /opt/c-relay/c_relay_x86
|
||||
|
||||
# Install systemd service
|
||||
sudo cp systemd/c-relay.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
```
|
||||
|
||||
### Service Management
|
||||
|
||||
#### Start and Enable Service
|
||||
```bash
|
||||
# Start the service
|
||||
sudo systemctl start c-relay
|
||||
|
||||
# Enable auto-start on boot
|
||||
sudo systemctl enable c-relay
|
||||
|
||||
# Check status
|
||||
sudo systemctl status c-relay
|
||||
```
|
||||
|
||||
#### Capture Admin Keys (CRITICAL)
|
||||
```bash
|
||||
# View startup logs to get admin keys
|
||||
sudo journalctl -u c-relay --since "5 minutes ago" | grep -A 10 "IMPORTANT: SAVE THIS ADMIN PRIVATE KEY"
|
||||
|
||||
# Or check the full log
|
||||
sudo journalctl -u c-relay --no-pager | grep "Admin Private Key"
|
||||
```
|
||||
|
||||
⚠️ **CRITICAL**: Save the admin private key immediately - it's only shown once and is needed for all configuration updates!
|
||||
|
||||
### Firewall Configuration
|
||||
|
||||
#### UFW (Ubuntu)
|
||||
```bash
|
||||
# Allow relay port
|
||||
sudo ufw allow 8888/tcp
|
||||
|
||||
# Allow SSH (ensure you don't lock yourself out)
|
||||
sudo ufw allow 22/tcp
|
||||
|
||||
# Enable firewall
|
||||
sudo ufw enable
|
||||
```
|
||||
|
||||
#### iptables
|
||||
```bash
|
||||
# Allow relay port
|
||||
sudo iptables -A INPUT -p tcp --dport 8888 -j ACCEPT
|
||||
|
||||
# Save rules (Ubuntu/Debian)
|
||||
sudo iptables-save > /etc/iptables/rules.v4
|
||||
```

|
||||
```
|
||||
|
||||
## Monitoring Setup
|
||||
|
||||
### System Monitoring
|
||||
|
||||
#### Basic Monitoring Script
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# /usr/local/bin/relay-monitor.sh
|
||||
|
||||
LOG_FILE="/var/log/relay-monitor.log"
|
||||
DATE=$(date '+%Y-%m-%d %H:%M:%S')
|
||||
|
||||
# Check if relay is running
|
||||
if ! pgrep -f "c_relay_x86" > /dev/null; then
|
||||
echo "[$DATE] ERROR: Relay process not running" >> $LOG_FILE
|
||||
systemctl restart c-relay
|
||||
fi
|
||||
|
||||
# Check port availability
|
||||
if ! netstat -tln | grep -q ":8888"; then
|
||||
echo "[$DATE] ERROR: Port 8888 not listening" >> $LOG_FILE
|
||||
fi
|
||||
|
||||
# Check database file
|
||||
RELAY_DB=$(find /opt/c-relay -name "*.nrdb" | head -1)
|
||||
if [[ -n "$RELAY_DB" ]]; then
|
||||
DB_SIZE=$(du -h "$RELAY_DB" | cut -f1)
|
||||
echo "[$DATE] INFO: Database size: $DB_SIZE" >> $LOG_FILE
|
||||
fi
|
||||
|
||||
# Check memory usage
|
||||
MEM_USAGE=$(ps aux | grep c_relay_x86 | grep -v grep | awk '{print $6}')
|
||||
if [[ -n "$MEM_USAGE" ]]; then
|
||||
echo "[$DATE] INFO: Memory usage: ${MEM_USAGE}KB" >> $LOG_FILE
|
||||
fi
|
||||
```
|
||||
|
||||
#### Cron Job Setup
|
||||
```bash
|
||||
# Add to crontab
|
||||
echo "*/5 * * * * /usr/local/bin/relay-monitor.sh" | sudo crontab -
|
||||
|
||||
# Make script executable
|
||||
sudo chmod +x /usr/local/bin/relay-monitor.sh
|
||||
```
|
||||
|
||||
### Log Aggregation
|
||||
|
||||
#### Centralized Logging with rsyslog
|
||||
```bash
|
||||
# /etc/rsyslog.d/50-c-relay.conf
|
||||
if $programname == 'c-relay' then /var/log/c-relay.log
|
||||
& stop
|
||||
```
|
||||
|
||||
### External Monitoring
|
||||
|
||||
#### Prometheus Integration
|
||||
```yaml
|
||||
# /etc/prometheus/prometheus.yml
|
||||
scrape_configs:
|
||||
- job_name: 'c-relay'
|
||||
static_configs:
|
||||
- targets: ['localhost:8888']
|
||||
metrics_path: '/metrics' # If implemented
|
||||
scrape_interval: 30s
|
||||
```
|
||||
|
||||
## Security Hardening
|
||||
|
||||
### System Hardening
|
||||
|
||||
#### Service User Restrictions
|
||||
```bash
|
||||
# Restrict service user
|
||||
sudo usermod -s /bin/false c-relay
|
||||
sudo usermod -d /opt/c-relay c-relay
|
||||
|
||||
# Set proper permissions
|
||||
sudo chmod 700 /opt/c-relay
|
||||
sudo chown -R c-relay:c-relay /opt/c-relay
|
||||
```
|
||||
|
||||
#### File System Restrictions
|
||||
```bash
|
||||
# Mount data directory with appropriate options
|
||||
echo "/dev/sdb /opt/c-relay ext4 defaults,noexec,nosuid,nodev 0 2" >> /etc/fstab
|
||||
```
|
||||
|
||||
### Network Security
|
||||
|
||||
#### Fail2Ban Configuration
|
||||
```ini
|
||||
# /etc/fail2ban/jail.d/c-relay.conf
|
||||
[c-relay-dos]
|
||||
enabled = true
|
||||
port = 8888
|
||||
filter = c-relay-dos
|
||||
logpath = /var/log/c-relay.log
|
||||
maxretry = 10
|
||||
findtime = 60
|
||||
bantime = 300
|
||||
```
|
||||
|
||||
#### DDoS Protection
|
||||
```bash
|
||||
# iptables rate limiting
|
||||
sudo iptables -A INPUT -p tcp --dport 8888 -m limit --limit 25/minute --limit-burst 100 -j ACCEPT
|
||||
sudo iptables -A INPUT -p tcp --dport 8888 -j DROP
|
||||
```
|
||||
|
||||
### Database Security
|
||||
|
||||
#### Encryption at Rest
|
||||
```bash
|

# Event-Based Configuration System Implementation Plan
|
||||
|
||||
## Overview
|
||||
|
||||
This document provides a detailed implementation plan for transitioning the C Nostr Relay from command line arguments and file-based configuration to a pure event-based configuration system using kind 33334 Nostr events stored directly in the database.

```
|
||||
|
||||
### Phase 5: Configuration Management
|
||||
|
||||
#### 5.1 Configuration Field Mapping
|
||||
**File:** `src/config.c`
|
||||
|
||||
```c
|
||||
// Map configuration tags to current system
|
||||
static const config_field_handler_t config_handlers[] = {
|
||||
{"auth_enabled", 0, apply_auth_enabled},
|
||||
{"relay_port", 1, apply_relay_port}, // requires restart
|
||||
{"max_connections", 0, apply_max_connections},
|
||||
{"relay_description", 0, apply_relay_description},
|
||||
{"relay_contact", 0, apply_relay_contact},

||||
// ... etc
|
||||
};
|
||||
```
|
||||
|
||||
#### 5.2 Startup Configuration Loading
|
||||
**File:** `src/main.c`
|
||||
|
||||
```c
|
||||
int startup_existing_relay(const char* relay_pubkey) {
|
||||
// 1. Open database
|
||||
if (init_database_with_pubkey(relay_pubkey) != 0) {
|
||||
return -1;
|
||||
}
|
||||
|
||||
// 2. Load configuration event from database
|
||||
cJSON* config_event = load_config_event_from_database(relay_pubkey);
|
||||
if (!config_event) {
|
||||
log_error("No configuration event found in database");
|
||||
return -1;
|
||||
}
|
||||
|
||||
// 3. Apply all configuration from event
|
||||
if (apply_configuration_from_event(config_event) != 0) {
|
||||
return -1;
|
||||
}
|
||||
|
||||
// 4. Continue with normal startup
|
||||
return start_relay_services();
|
||||
}
|
||||
```
|
||||
|
||||

4. ⏳ Performance testing and optimization (pending)
|
||||
|
||||
## Migration Strategy
|
||||
|
||||
### For Existing Installations
|
||||
Since the new system uses a completely different approach:
|
||||
|
||||
1. **No Automatic Migration**: The new system starts fresh
|
||||
2. **Manual Migration**: Users can manually copy configuration values
|
||||
3. **Documentation**: Provide clear migration instructions
|
||||
4. **Coexistence**: Old and new systems use different database names
|
||||
|
||||
### Migration Steps for Users
|
||||
1. Stop existing relay
|
||||
2. Note current configuration values
|
||||
3. Start new relay (generates keys and new database)
|
||||
4. Create kind 33334 event with desired configuration using admin private key
|
||||
5. Send event to relay to update configuration
|
||||
|
||||
## Testing Requirements
|
||||
|
||||
### Unit Tests
|
||||
- Key generation functions
|
||||
- Configuration event creation and validation
|
||||
- Database naming logic
|
||||
- Configuration application handlers
|
||||
|
||||
### Integration Tests
|
||||
- Complete first-time startup flow
|
||||
- Configuration update via events
|
||||
- Error handling scenarios
|
||||
- Database operations
|
||||
|
||||
### Performance Tests
|
||||
- Startup time comparison
|
||||
- Configuration update response time
|
||||
- Memory usage analysis
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **Admin Private Key**: Never stored, only printed once
|
||||
2. **Event Validation**: All configuration events must be signed by admin
|
||||
3. **Database Security**: Relay database contains relay private key
|
||||
4. **Key Generation**: Use `nostr_core_lib` for cryptographically secure generation
|
||||
|
||||
## Files to Modify
|
||||
|
||||
### Major Changes
|
||||
- `src/main.c` - Startup logic, event processing, argument removal
|
||||
- `src/config.c` - Complete rewrite for event-based configuration
|
||||
- `src/config.h` - Update function signatures and structures
|
||||
- `src/sql_schema.h` - Remove config tables
|
||||
|
||||
### Minor Changes
|
||||
- `Makefile` - Remove any config file generation
|
||||
- `systemd/` - Update service files if needed
|
||||
- Documentation updates
|
||||
|
||||
## Backwards Compatibility
|
||||
|
||||
**Breaking Changes:**
|
||||
- Command line arguments removed (except --help, --version)
|
||||
- Configuration files no longer used
|
||||
- Database naming scheme changed
|
||||
- Configuration table removed
|
||||
|
||||
**Migration Required:** This is a breaking change that requires manual migration for existing installations.
|
||||
|
||||
## Success Criteria - CURRENT STATUS
|
||||
|
||||
1. ✅ **Zero Command Line Arguments**: Relay starts with just `./c-relay`
|
||||
2. ✅ **Automatic First-Time Setup**: Generates keys and database automatically
|
||||
3. ⚠️ **Real-Time Configuration**: Infrastructure ready, handlers need completion
|
||||
4. ✅ **Single Database File**: All configuration and data in one `.nrdb` file
|
||||
5. ⚠️ **Admin Control**: Event processing implemented, signature validation ready
|
||||
6. ⚠️ **Clean Codebase**: Most legacy code removed, database tables cleanup pending
|
||||
|
||||
## Risk Mitigation
|
||||
|
||||
1. **Backup Strategy**: Document manual backup procedures for relay database
|
||||
2. **Key Loss Recovery**: Document recovery procedures if admin key is lost
|
||||
3. **Testing Coverage**: Comprehensive test suite before deployment
|
||||
4. **Rollback Plan**: Keep old version available during transition period
|
||||
5. **Documentation**: Comprehensive user and developer documentation
|
||||
|
||||
This implementation plan provides a clear path from the current system to the new event-based configuration architecture while maintaining security and reliability.

# File-Based Configuration Architecture Design
|
||||
|
||||
## Overview
|
||||
This document outlines the XDG-compliant file-based configuration system for the C Nostr Relay, following the Ginxsom admin system approach using signed Nostr events.
|
||||
|
||||
## XDG Base Directory Specification Compliance
|
||||
|
||||
### File Location Strategy
|
||||
|
||||
**Primary Location:**
|
||||
```
|
||||
$XDG_CONFIG_HOME/c-relay/c_relay_config_event.json
|
||||
```
|
||||
|
||||
**Fallback Location:**
|
||||
```
|
||||
$HOME/.config/c-relay/c_relay_config_event.json
|
||||
```
|
||||
|
||||
**System-wide Fallback:**
|
||||
```
|
||||
/etc/c-relay/c_relay_config_event.json
|
||||
```
|
||||
|
||||
### Directory Structure
|
||||
```
|
||||
$XDG_CONFIG_HOME/c-relay/
|
||||
├── c_relay_config_event.json # Main configuration file
|
||||
├── backup/ # Configuration backups
|
||||
│ ├── c_relay_config_event.json.bak
|
||||
│ └── c_relay_config_event.20241205.json
|
||||
└── validation/ # Validation logs
|
||||
└── config_validation.log
|
||||
```
|
||||
|
||||
## Configuration File Format
|
||||
|
||||
### Signed Nostr Event Structure
|
||||
|
||||
The configuration file contains a signed Nostr event (kind 33334) with relay configuration:
|
||||
|
||||
```json
|
||||
{
|
||||
"kind": 33334,
|
||||
"created_at": 1704067200,
|
||||
"tags": [
|
||||
["relay_name", "C Nostr Relay"],
|
||||
["relay_description", "High-performance C Nostr relay with SQLite storage"],
|
||||
["relay_port", "8888"],

### Event Kind Definition
|
||||
|
||||
**Kind 33334**: C Nostr Relay Configuration Event
|
||||
- Parameterized replaceable event
|
||||
- Must be signed by authorized admin pubkey
|
||||
- Contains relay configuration as tags
|
||||
- Validation required on load
|
||||
|
||||
## Configuration Loading Architecture
|
||||
|
||||
### Loading Priority Chain
|
||||
|
||||
1. **Command Line Arguments** (highest priority)
|
||||
2. **File-based Configuration** (signed Nostr event)
|
||||
3. **Database Configuration** (persistent storage)
|
||||
4. **Environment Variables** (compatibility mode)
|
||||
5. **Hardcoded Defaults** (fallback)
|
||||
|
||||

## C Implementation Architecture
|
||||
|
||||
### Core Data Structures
|
||||
|
||||
```c
|
||||
// Configuration file management
|
||||
typedef struct {
|
||||
char file_path[512];
|
||||
char file_hash[65]; // SHA256 hash
|
||||
time_t last_modified;
|
||||
time_t last_loaded;
|
||||
int validation_status; // 0=valid, 1=invalid, 2=unverified
|
||||
char validation_error[256];
|
||||
} config_file_info_t;
|
||||
|
||||
// Configuration event structure
|
||||
typedef struct {
|
||||
char event_id[65];
|
||||
char pubkey[65];
|
||||
char signature[129];
|
||||
long created_at;
|
||||
int kind;
|
||||
cJSON* tags;
|
||||
char* content;
|
||||
} config_event_t;
|
||||
|
||||
// Configuration management context
|
||||
typedef struct {
|
||||
config_file_info_t file_info;
|
||||
config_event_t event;
|
||||
int loaded_from_file;
|
||||
int loaded_from_database;
|
||||
char admin_pubkey[65];
|
||||
time_t load_timestamp;
|
||||
} config_context_t;
|
||||
```
|
||||
|
||||
### Core Function Signatures
|
||||
|
||||
```c
|
||||
// XDG path resolution
|
||||
int get_config_file_path(char* path, size_t path_size);
|
||||
int create_config_directories(const char* config_path);
|
||||
|
||||
// File operations
|
||||
int load_config_from_file(const char* config_path, config_context_t* ctx);
|
||||
int save_config_to_file(const char* config_path, const config_event_t* event);
|
||||
int backup_config_file(const char* config_path);
|
||||
|
||||
// Event validation
|
||||
int validate_config_event_structure(const cJSON* event);
|
||||
int verify_config_event_signature(const config_event_t* event, const char* admin_pubkey);
|
||||
int validate_config_tag_values(const cJSON* tags);
|
||||
|
||||
// Configuration extraction and application

int log_config_validation_error(const char* config_key, const char* error);
|
||||
int log_config_load_event(const config_context_t* ctx, const char* source);
|
||||
```
|
||||
|
||||
## Configuration Validation Rules
|
||||
|
||||
### Event Structure Validation
|
||||
|
||||
1. **Required Fields**: `kind`, `created_at`, `tags`, `content`, `pubkey`, `id`, `sig`
|
||||
2. **Kind Validation**: Must be exactly 33334
|
||||
3. **Timestamp Validation**: Must be reasonable (not too old, not future)
|
||||
4. **Tags Format**: Array of string arrays `[["key", "value"], ...]`
|
||||
5. **Signature Verification**: Must be signed by authorized admin pubkey
|
||||
|
||||
### Configuration Value Validation
|
||||
|
||||
```c
|
||||
typedef struct {
|
||||
char* key;
|
||||
char* data_type; // "string", "integer", "boolean", "json"
|
||||
char* validation_rule; // JSON validation rule
|
||||
int required;
|
||||
char* default_value;
|
||||
} config_validation_rule_t;
|
||||
|
||||
static config_validation_rule_t validation_rules[] = {
|
||||
{"relay_port", "integer", "{\"min\": 1, \"max\": 65535}", 1, "8888"},
|
||||
{"pow_min_difficulty", "integer", "{\"min\": 0, \"max\": 64}", 1, "0"},
|
||||
{"expiration_grace_period", "integer", "{\"min\": 0, \"max\": 86400}", 1, "300"},
|
||||
{"admin_pubkey", "string", "{\"pattern\": \"^[0-9a-fA-F]{64}$\"}", 0, ""},
|
||||
{"pow_enabled", "boolean", "{}", 1, "true"},
|
||||
// ... more rules
|
||||
};
|
||||
```
|
||||
|
||||
### Security Validation
|
||||
|
||||
1. **Admin Pubkey Verification**: Only configured admin pubkeys can create config events
|
||||
2. **Event ID Verification**: Event ID must match computed hash
|
||||
3. **Signature Verification**: Signature must be valid for the event and pubkey
|
||||
4. **Timestamp Validation**: Prevent replay attacks with old events
|
||||
5. **File Permission Checks**: Config files should have appropriate permissions
|
||||
|
||||
## File Management Features
|
||||
|
||||
### Configuration File Operations
|
||||
|
||||
**File Creation:**
|
||||
- Generate initial configuration file with default values
|
||||
- Sign with admin private key
|
||||
- Set appropriate file permissions (600 - owner read/write only)
|
||||
|
||||
**File Updates:**
|
||||
- Create backup of existing file
|
||||
- Validate new configuration
|
||||
- Atomic file replacement (write to temp, then rename)
|
||||
- Update file metadata cache
|
||||
|
||||
**File Monitoring:**
|
||||
- Watch for file system changes using inotify (Linux)
|
||||
- Reload configuration automatically when file changes
|
||||
- Validate changes before applying
|
||||
- Log all configuration reload events
|
||||
|
||||
### Backup and Recovery
|
||||
|
||||
**Automatic Backups:**
|
||||
```
|
||||
$XDG_CONFIG_HOME/c-relay/backup/
|
||||
├── c_relay_config_event.json.bak # Last working config
|
||||
├── c_relay_config_event.20241205-143022.json # Timestamped backups
|
||||
└── c_relay_config_event.20241204-091530.json
|
||||
```
|
||||
|
||||
**Recovery Process:**
|
||||
1. Detect corrupted or invalid config file
|
||||
2. Attempt to load from `.bak` backup
|
||||
3. If backup fails, generate default configuration
|
||||
4. Log recovery actions for audit
|
||||
|
||||
## Integration with Database Schema
|
||||
|
||||
### File-Database Synchronization
|
||||
|
||||
**On File Load:**
|
||||
1. Parse and validate file-based configuration
|
||||
2. Extract configuration values from event tags
|
||||
3. Update database `server_config` table
|
||||
4. Record file metadata in `config_file_cache` table
|
||||
5. Log configuration changes in `config_history` table
|
||||
|
||||
**Configuration Priority Resolution:**
|
||||
```c
|
||||
char* get_config_value(const char* key, const char* default_value) {
|
||||
// Priority: CLI args > File config > DB config > Env vars > Default
|
||||
char* value = NULL;
|
||||
|
||||
// 1. Check command line overrides (if implemented)
|
||||
value = get_cli_override(key);
|
||||
if (value) return value;
|
||||
|
||||
// 2. Check database (updated from file)
|
||||
value = get_database_config(key);
|
||||
if (value) return value;
|
||||
|
||||
// 3. Check environment variables (compatibility)
|
||||
value = get_env_config(key);
|
||||
if (value) return value;
|
||||
|
||||
// 4. Return default
|
||||
return strdup(default_value);
|
||||
}
|
||||
```
|
||||
|
||||
## Error Handling and Recovery
|
||||
|
||||
### Validation Error Handling
|
||||
|
||||
```c
|
||||
typedef enum {
|
||||
CONFIG_ERROR_NONE = 0,
|
||||
CONFIG_ERROR_FILE_NOT_FOUND = 1,
|
||||
CONFIG_ERROR_PARSE_FAILED = 2,
|
||||
CONFIG_ERROR_INVALID_STRUCTURE = 3,
|
||||
CONFIG_ERROR_SIGNATURE_INVALID = 4,
|
||||
CONFIG_ERROR_UNAUTHORIZED = 5,
|
||||
CONFIG_ERROR_VALUE_INVALID = 6,
|
||||
CONFIG_ERROR_IO_ERROR = 7
|
||||
} config_error_t;
|
||||
|
||||
typedef struct {
|
||||
config_error_t error_code;
|
||||
char error_message[256];
|
||||
char config_key[64];
|
||||
char invalid_value[128];
|
||||
time_t error_timestamp;
|
||||
} config_error_info_t;
|
||||
```
|
||||
|
||||
### Graceful Degradation
|
||||
|
||||
**File Load Failure:**
|
||||
1. Log detailed error information
|
||||
2. Fall back to database configuration
|
||||
3. Continue operation with last known good config
|
||||
4. Set service status to "degraded" mode
|
||||
|
||||
**Validation Failure:**
|
||||
1. Log validation errors with specific details
|
||||
2. Skip invalid configuration items
|
||||
3. Use default values for failed items
|
||||
4. Continue with partial configuration
|
||||
|
||||
**Permission Errors:**
|
||||
1. Log permission issues
|
||||
2. Attempt to use fallback locations
|
||||
3. Generate temporary config if needed
|
||||
4. Alert administrator via logs
|
||||
|
||||
## Configuration Update Process
|
||||
|
||||
### Safe Configuration Updates
|
||||
|
||||
**Atomic Update Process:**
|
||||
1. Create backup of current configuration
|
||||
2. Write new configuration to temporary file
|
||||
3. Validate new configuration completely
|
||||
4. If valid, rename temporary file to active config
|
||||
5. Update database with new values
|
||||
6. Apply changes to running server
|
||||
7. Log successful update
|
||||
|
||||
**Rollback Process:**
|
||||
1. Detect invalid configuration at startup
|
||||
2. Restore from backup file
|
||||
3. Log rollback event
|
||||
4. Continue with previous working configuration
|
||||
|
||||
### Hot Reload Support
|
||||
|
||||
**File Change Detection:**
|
||||
```c
|
||||
int monitor_config_file_changes(const char* config_path) {
|
||||
// Use inotify on Linux to watch file changes
|
||||
int inotify_fd = inotify_init();
|
||||
int watch_fd = inotify_add_watch(inotify_fd, config_path, IN_MODIFY | IN_MOVED_TO);
|
||||
|
||||
// Monitor in separate thread
|
||||
// On change: validate -> apply -> log
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
**Runtime Configuration Updates:**
|
||||
- Reload configuration on file change
|
||||
- Apply non-restart-required changes immediately
|
||||
- Queue restart-required changes for next restart
|
||||
- Notify operators of configuration changes
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Access Control
|
||||
|
||||
**File Permissions:**
|
||||
- Config files: 600 (owner read/write only)
|
||||
- Directories: 700 (owner access only)
|
||||
- Backup files: 600 (owner read/write only)
|
||||
|
||||
**Admin Key Management:**
|
||||
- Admin private keys never stored in config files
|
||||
- Only admin pubkeys stored for verification
|
||||
- Support for multiple admin pubkeys
|
||||
- Key rotation support
|
||||
|
||||
### Signature Validation
|
||||
|
||||
**Event Signature Verification:**
|
||||
```c
|
||||
int verify_config_event_signature(const config_event_t* event, const char* admin_pubkey) {
|
||||
// 1. Reconstruct event for signing (without id and sig)
|
||||
// 2. Compute event ID and verify against stored ID
|
||||
// 3. Verify signature using admin pubkey
|
||||
// 4. Check admin pubkey authorization
|
||||
return NOSTR_SUCCESS;
|
||||
}
|
||||
```
|
||||
|
||||
**Anti-Replay Protection:**
|
||||
- Configuration events must be newer than current
|
||||
- Event timestamps validated against reasonable bounds
|
||||
- Configuration history prevents replay attacks
|
||||
|
||||
## Implementation Phases
|
||||
|
||||

|
||||
|
||||
### Interactive Setup Script
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# scripts/setup_config.sh - Interactive configuration setup
|
||||
|
||||
create_initial_config() {
|
||||
echo "=== C Nostr Relay Initial Configuration ==="
|
||||
|
||||
# Collect basic information
|
||||
read -p "Relay name [C Nostr Relay]: " relay_name
|
||||
read -p "Admin public key (hex): " admin_pubkey
|
||||
read -p "Server port [8888]: " server_port
|
||||
|
||||
# Generate signed configuration event
|
||||
./scripts/generate_config.sh \
|
||||
--admin-key "$admin_pubkey" \
|
||||
--relay-name "${relay_name:-C Nostr Relay}" \
|
||||
--port "${server_port:-8888}" \
|
||||
--output "$XDG_CONFIG_HOME/c-relay/c_relay_config_event.json"
|
||||
}
|
||||
```
|
||||
|
||||
### Configuration Validation Utility
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# scripts/validate_config.sh - Validate configuration file
|
||||
|
||||
validate_config_file() {
|
||||
local config_file="$1"
|
||||
|
||||
# Check file exists and is readable
|
||||
# Validate JSON structure
|
||||
# Verify event signature
|
||||
# Check configuration values
|
||||
# Report validation results
|
||||
}
|
||||
```
|
||||
|
||||
This comprehensive file-based configuration design provides a robust, secure, and maintainable system that follows industry standards while integrating seamlessly with the existing C Nostr Relay architecture.

# Startup Configuration Design Analysis
|
||||
|
||||
## Review of startup_config_design.md
|
||||
|
||||
### Key Design Principles Identified
|
||||
|
||||
1. **Zero Command Line Arguments**: Complete elimination of CLI arguments for true "quick start"
|
||||
2. **Event-Based Configuration**: Configuration stored as Nostr event (kind 33334) in events table
|
||||
3. **Self-Contained Database**: Database named after relay pubkey (`<pubkey>.nrdb`)
|
||||
4. **First-Time Setup**: Automatic key generation and initial configuration creation
|
||||
5. **Configuration Consistency**: Always read from event, never from hardcoded defaults
|
||||
|
||||
### Implementation Gaps and Specifications Needed
|
||||
|
||||
#### 1. Key Generation Process
|
||||
**Specification:**
|
||||
```
|
||||
First Startup Key Generation:
|
||||
1. Generate all keys on first startup (admin private/public, relay private/public)
|
||||
2. Use nostr_core_lib for key generation entropy
|
||||
3. Keys are encoded in hex format
|
||||
4. Print admin private key to stdout for user to save (never stored)
|
||||
5. Store admin public key, relay private key, and relay public key in configuration event
|
||||
6. Admin can later change the 33334 event to alter stored keys
|
||||
```
|
||||
|
||||
#### 2. Database Naming and Location
|
||||
**Specification:**
|
||||
```
|
||||
Database Naming:
|
||||
1. Database is named using relay pubkey: ./<relay_pubkey>.nrdb
|
||||
2. Database path structure: ./<relay_pubkey>.nrdb
|
||||
3. If database creation fails, program quits (can't run without database)
|
||||
4. c_nostr_relay.db should never exist in new system
|
||||
```
|
||||
|
||||
#### 3. Configuration Event Structure (Kind 33334)
|
||||
**Specification:**
|
||||
```
|
||||
Event Structure:
|
||||
- Kind: 33334 (parameterized replaceable event)
|
||||
- Event validation: Use nostr_core_lib to validate event
|
||||
- Event content field: "C Nostr Relay Configuration" (descriptive text)
|
||||
- Configuration update mechanism: TBD
|
||||
- Complete tag structure provided in configuration section below
|
||||
```
|
||||
|
||||
|
||||
|
||||
#### 4. Configuration Change Monitoring
|
||||
**Configuration Monitoring System:**
|
||||
```
|
||||
Every event that is received is checked to see if it is a kind 33334 event from the admin pubkey.
|
||||
If so, it is processed as a configuration update.
|
||||
```
|
||||
|
||||
#### 5. Error Handling and Recovery
|
||||
**Specification:**
|
||||
```
|
||||
Error Recovery Priority:
|
||||
1. Try to load latest valid config event
|
||||
2. Generate new default configuration event if none exists
|
||||
3. Exit with error if all recovery attempts fail
|
||||
|
||||
Note: There is only ever one configuration event (parameterized replaceable event),
|
||||
so no fallback to previous versions.
|
||||
```
|
||||
|
||||
### Design Clarifications
|
||||
|
||||
**Key Management:**
|
||||
- Admin private key is never stored, only printed once at first startup
|
||||
- Single admin system (no multi-admin support)
|
||||
- No key rotation support
|
||||
|
||||
**Configuration Management:**
|
||||
- No configuration versioning/timestamping
|
||||
- No automatic backup of configuration events
|
||||
- Configuration events are not broadcastable to other relays
|
||||
- Future: Auth system to restrict admin access to configuration events
|
||||

||||
## Complete Current Configuration Structure
|
||||
|
||||
Based on analysis of [`src/config.c`](src/config.c:753-795), here is the complete current configuration structure that will be converted to event tags:

```
|
||||
|
||||

# Startup and configuration for c_nostr_relay
|
||||
|
||||
No command line variables. Quick start.
|
||||
|
||||
## First time startup
|
||||
When the program first starts, it generates a new private and public keys for the program, and for the admin. In the command line it prints out the private key for the admin. It creates a database in the same directory as the application. It names the database after the pubkey of the database <pubkey>.nrdb (This stands for nostr relay db)
|
||||
|
||||
Internally, it creates a valid nostr event using the generated admin private key, and saves it to the events table in the db. That nostr configuration event is a type 33334 event, with a d tag that equals the database public key d=<db pubkey>.
|
||||
|
||||
The event is populated from internal default values. Then the configuration setup is run by reading the event from the database events table.
|
||||
|
||||
Important, the constant values are ALWAYS read and set from the 33334 event in the events table, they are NEVER read from the stored default values. This is important for consistancy.
|
||||
|
||||
The config section of the program keeps track of the admin file, and if it ever changes, it does what is needed to implement the change.
|
||||
|
||||
|
||||
## Later startups
|
||||
The program looks for the database with the name c_nostr_relay.db in the same directory as the program. If it doesn't find it, it assumes a first time startup. If it does find it, it loads the database, and the config section reads the config event and proceedes from there.
|
||||
|
||||
## Changing database location?
|
||||
Changing the location of the databases can be done by creating a sym-link to the new location of the database.

|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Build and Start
|
||||
```bash
|
||||
# Clone and build
|
||||
git clone <repository-url>
|
||||
cd c-relay
|
||||
git submodule update --init --recursive
|
||||
make
|
||||
|
||||
# Start relay (zero configuration needed)
|
||||
./build/c_relay_x86
|
||||
```
|
||||
|
||||
### 2. First Startup - Save Keys
|
||||
The relay will display admin keys on first startup:
|
||||
|
||||
```
|
||||
=================================================================
|
||||
IMPORTANT: SAVE THIS ADMIN PRIVATE KEY SECURELY!
|
||||
=================================================================
|
||||
Admin Private Key: a018ecc259ff296ef7aaca6cdccbc52cf28104ac7a1f14c27b0b8232e5025ddc
|
||||
Admin Public Key: 68394d08ab87f936a42ff2deb15a84fbdfbe0996ee0eb20cda064aae673285d1
|
||||
=================================================================
|
||||
```
|
||||
|
||||
⚠️ **CRITICAL**: Save the admin private key - it's needed for configuration updates and only shown once!
|
||||
|
||||
### 3. Connect Clients
|
||||
Your relay is now available at:
|
||||
- **WebSocket**: `ws://localhost:8888`
|
||||
- **NIP-11 Info**: `http://localhost:8888`
|
||||
|
||||
## Installation
|
||||
|
||||
### System Requirements
|
||||
- **Operating System**: Linux, macOS, or Windows (WSL)
|
||||
- **RAM**: Minimum 512MB, recommended 2GB+
|
||||
- **Disk**: 100MB for binary + database storage (grows with events)
|
||||
- **Network**: Port 8888 (configurable via events)
|
||||
|
||||

```
|
||||
|
||||
### Building from Source
|
||||
```bash
|
||||
# Clone repository
|
||||
git clone <repository-url>
|
||||
cd c-relay
|
||||

|
||||
|
||||
# Verify build
|
||||
ls -la build/c_relay_x86
|
||||
```
|
||||
|
||||
### Production Deployment
|
||||
|
||||
#### SystemD Service (Recommended)
|
||||
```bash
|
||||
# Install as system service
|
||||
sudo systemd/install-service.sh
|
||||
|
||||
# Start service
|
||||
sudo systemctl start c-relay
|
||||
|
||||
# Enable auto-start
|
||||
sudo systemctl enable c-relay
|
||||
|
||||
# Check status
|
||||
sudo systemctl status c-relay
|
||||
```
|
||||
|
||||
#### Manual Deployment
|
||||
```bash
|
||||
# Create dedicated user
|
||||
sudo useradd --system --home-dir /opt/c-relay --shell /bin/false c-relay
|
||||
|
||||
# Install binary
|
||||
sudo mkdir -p /opt/c-relay
|
||||
sudo cp build/c_relay_x86 /opt/c-relay/
|
||||
sudo chown -R c-relay:c-relay /opt/c-relay
|
||||
|
||||
# Run as service user
|
||||
sudo -u c-relay /opt/c-relay/c_relay_x86
|
||||
```
|
||||
|
||||
## Configuration Management
|
||||
|
||||
### Event-Based Configuration System
|
||||
|
||||
Unlike traditional relays that use config files, this relay stores all configuration as **kind 33334 Nostr events** in the database. This provides:
|
||||
|
||||
- **Real-time updates**: Changes applied instantly without restart
|
||||
- **Cryptographic security**: All config changes must be signed by admin
|
||||
- **Audit trail**: Complete history of configuration changes
|
||||
- **No file management**: No config files to manage or version control
|
||||
|
||||
### First-Time Configuration
|
||||
|
||||
On first startup, the relay:
|
||||
|
||||
1. **Generates keypairs**: Creates cryptographically secure admin and relay keys
|
||||
2. **Creates database**: `<relay_pubkey>.nrdb` file with optimized schema
|
||||
3. **Stores default config**: Creates initial kind 33334 event with sensible defaults
|
||||
4. **Displays admin key**: Shows admin private key once for you to save
|
||||
|
||||
### Updating Configuration
|
||||
|
||||
To change relay configuration, create and send a signed kind 33334 event:
|
||||
|
||||
#### Using nostrtool (recommended)
|
||||
```bash
|
||||
# Install nostrtool
|
||||
npm install -g nostrtool
|
||||
|
||||
# Update relay description
|
||||
nostrtool event \
|
||||
--kind 33334 \
|
||||
--content "C Nostr Relay Configuration" \
|
||||
--tag d <relay_pubkey> \
|
||||
--tag relay_description "My Production Relay" \
|
||||
--tag max_subscriptions_per_client 50 \
|
||||
--private-key <admin_private_key> \
|
||||
| nostrtool send ws://localhost:8888
|
||||
```
|
||||
|
||||
#### Manual Event Creation
|
||||
```json
|
||||
{
|
||||
"kind": 33334,
|
||||
"content": "C Nostr Relay Configuration",
|
||||
"tags": [
|
||||
["d", "<relay_pubkey>"],
|
||||
["relay_description", "My Production Relay"],
|
||||
["max_subscriptions_per_client", "50"],
|
||||
["pow_min_difficulty", "20"]
|
||||
],
|
||||
"created_at": 1699123456,
|
||||
"pubkey": "<admin_pubkey>",
|
||||
"id": "<computed_event_id>",
|
||||
"sig": "<signature>"
|
||||
}
|
||||
```
|
||||
|
||||
Send this to your relay via WebSocket, and changes are applied immediately.

## Administration
|
||||
|
||||
### Viewing Current Configuration
|
||||
```bash
|
||||
# Find your database
|
||||
ls -la *.nrdb
|
||||
|
||||
# View configuration events
|
||||
sqlite3 <relay_pubkey>.nrdb "SELECT created_at, tags FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
|
||||
|
||||
# View all configuration history
|
||||
sqlite3 <relay_pubkey>.nrdb "SELECT datetime(created_at, 'unixepoch') as date, tags FROM events WHERE kind = 33334 ORDER BY created_at DESC;"
|
||||
```
|
||||
|
||||
### Admin Key Management
|
||||
|
||||
#### Backup Admin Keys
|
||||
```bash
|
||||
# Create secure backup
|
||||
echo "Admin Private Key: <your_admin_key>" > admin_keys_backup_$(date +%Y%m%d).txt
|
||||
chmod 600 admin_keys_backup_*.txt
|
||||
|
||||
# Store in secure location (password manager, encrypted drive, etc.)
|
||||
```
|
||||
|
||||
#### Key Recovery
|
||||
If you lose your admin private key:
|
||||
|
||||
1. **Stop the relay**: `pkill c_relay` or `sudo systemctl stop c-relay`
|
||||
2. **Backup events**: `cp <relay_pubkey>.nrdb backup_$(date +%Y%m%d).nrdb`
|
||||
3. **Remove database**: `rm <relay_pubkey>.nrdb*`
|
||||
4. **Restart relay**: This creates new database with new keys
|
||||
5. **⚠️ Note**: All stored events and configuration history will be lost
|
||||
|
||||
### Security Best Practices
|
||||
|
||||
#### Admin Key Security
|
||||
- **Never share** the admin private key
|
||||
- **Store securely** in password manager or encrypted storage
|
||||
- **Backup safely** to multiple secure locations
|
||||
- **Monitor** configuration changes in logs
|
||||
|
||||
#### Network Security
|
||||
```bash
|
||||
# Restrict access with firewall
|
||||
sudo ufw allow 8888/tcp
|
||||
|
||||
# Use reverse proxy for HTTPS (recommended)
|
||||
# Configure nginx/apache to proxy to ws://localhost:8888
|
||||
```
|
||||
|
||||
#### Database Security
|
||||
```bash
|
||||
# Secure database file permissions
|
||||
chmod 600 <relay_pubkey>.nrdb
|
||||
chown c-relay:c-relay <relay_pubkey>.nrdb
|
||||
|
||||
# Regular backups
|
||||
cp <relay_pubkey>.nrdb backup/relay_backup_$(date +%Y%m%d_%H%M%S).nrdb
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Service Status
|
||||
```bash
|
||||
# Check if relay is running
|
||||
ps aux | grep c_relay
|
||||
|
||||
# SystemD status
|
||||
sudo systemctl status c-relay
|
||||
|
||||
# Network connections
|
||||
netstat -tln | grep 8888
|
||||
sudo ss -tlpn | grep 8888
|
||||
```
|
||||
|
||||
### Log Monitoring
|
||||
```bash
|
||||
# Real-time logs (systemd)
|
||||
sudo journalctl -u c-relay -f
|
||||
|
||||
# Recent logs
|
||||
sudo journalctl -u c-relay --since "1 hour ago"
|
||||
|
||||
# Error logs only
|
||||
sudo journalctl -u c-relay -p err
|
||||
|
||||
# Configuration changes
|
||||
sudo journalctl -u c-relay | grep "Configuration updated via kind 33334"
|
||||
```
|
||||
|
||||
### Database Analytics
|
||||
```bash
|
||||
# Connect to database
|
||||
sqlite3 <relay_pubkey>.nrdb
|
||||
|
||||
# Event statistics
|
||||
SELECT event_type, COUNT(*) as count FROM events GROUP BY event_type;
|
||||
|
||||
# Recent activity
|
||||
SELECT datetime(created_at, 'unixepoch') as date, kind, LENGTH(content) as content_size
|
||||
FROM events
|
||||
ORDER BY created_at DESC
|
||||
LIMIT 10;
|
||||
|
||||
# Subscription analytics (if logging enabled)
|
||||
SELECT * FROM subscription_analytics ORDER BY date DESC LIMIT 7;
|
||||
|
||||
# Configuration changes
|
||||
SELECT datetime(created_at, 'unixepoch') as date, tags
|
||||
FROM configuration_events
|
||||
ORDER BY created_at DESC;
|
||||
```
|
||||
|
||||
### Performance Monitoring
|
||||
```bash
|
||||
# Database size
|
||||
du -sh <relay_pubkey>.nrdb*
|
||||
|
||||
# Memory usage
|
||||
ps aux | grep c_relay | awk '{print $6}' # RSS memory in KB
|
||||
|
||||
# Connection count (approximate)
|
||||
netstat -an | grep :8888 | grep ESTABLISHED | wc -l
|
||||
|
||||
# System resources
|
||||
top -p $(pgrep c_relay)
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### Relay Won't Start
|
||||
```bash
|
||||
# Check port availability
|
||||
netstat -tln | grep 8888
|
||||
# If port in use, find process: sudo lsof -i :8888
|
||||
|
||||
# Check binary permissions
|
||||
ls -la build/c_relay_x86
|
||||
chmod +x build/c_relay_x86
|
||||
|
||||
# Check dependencies
|
||||
ldd build/c_relay_x86
|
||||
```
|
||||
|
||||
#### Configuration Not Updating
|
||||
1. **Verify signature**: Ensure event is properly signed with admin private key
|
||||
2. **Check admin pubkey**: Must match the pubkey from first startup
|
||||
3. **Validate event structure**: Use `nostrtool validate` or similar
|
||||
4. **Check logs**: Look for validation errors in relay logs
|
||||
5. **Test WebSocket**: Ensure WebSocket connection is active
|
||||
|
||||
```bash
|
||||
# Test WebSocket connection
|
||||
wscat -c ws://localhost:8888
|
||||
|
||||
# Send test message
|
||||
{"id":"test","method":"REQ","params":["test",{}]}
|
||||
```
|
||||
|
||||
#### Database Issues
|
||||
```bash
|
||||
# Check database integrity
|
||||
sqlite3 <relay_pubkey>.nrdb "PRAGMA integrity_check;"
|
||||
|
||||
# Check schema version
|
||||
sqlite3 <relay_pubkey>.nrdb "SELECT * FROM schema_info WHERE key = 'version';"
|
||||
|
||||
# View database size and stats
|
||||
sqlite3 <relay_pubkey>.nrdb "PRAGMA page_size; PRAGMA page_count;"
|
||||
```
|
||||
|
||||
#### Performance Issues
|
||||
```bash
|
||||
# Analyze slow queries (if any)
|
||||
sqlite3 <relay_pubkey>.nrdb "PRAGMA compile_options;"
|
||||
|
||||
# Check database optimization
|
||||
sqlite3 <relay_pubkey>.nrdb "PRAGMA optimize;"
|
||||
|
||||
# Monitor system resources
|
||||
iostat 1 5 # I/O statistics
|
||||
free -h # Memory usage
|
||||
```
|
||||
|
||||
### Recovery Procedures
|
||||
|
||||
#### Corrupted Database Recovery
|
||||
```bash
|
||||
# Attempt repair
|
||||
sqlite3 <relay_pubkey>.nrdb ".recover" > recovered.sql
|
||||
sqlite3 recovered.nrdb < recovered.sql
|
||||
|
||||
# If repair fails, start fresh (loses all events)
|
||||
mv <relay_pubkey>.nrdb <relay_pubkey>.nrdb.corrupted
|
||||
./build/c_relay_x86 # Creates new database
|
||||
```
|
||||
|
||||
#### Lost Configuration Recovery
|
||||
If configuration is lost but database is intact:
|
||||
|
||||
1. **Find old config**: `sqlite3 <relay_pubkey>.nrdb "SELECT * FROM configuration_events;"`
|
||||
2. **Create new config event**: Use last known good configuration
|
||||
3. **Sign and send**: Update with current timestamp and new signature
|
||||
|
||||
#### Emergency Restart
|
||||
```bash
|
||||
# Quick restart with clean state
|
||||
sudo systemctl stop c-relay
|
||||
mv <relay_pubkey>.nrdb <relay_pubkey>.nrdb.backup
|
||||
sudo systemctl start c-relay
|
||||
|
||||
# Check logs for new admin keys
|
||||
sudo journalctl -u c-relay --since "5 minutes ago" | grep "Admin Private Key"
|
||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Custom Event Handlers
|
||||
The relay supports custom handling for different event types. Configuration changes trigger:
|
||||
|
||||
- **Subscription Manager Updates**: When client limits change
|
||||
- **PoW System Reinitialization**: When PoW settings change
|
||||
- **Expiration System Updates**: When NIP-40 settings change
|
||||
- **Relay Info Updates**: When NIP-11 information changes
|
||||
|
||||
### API Integration
|
||||
```javascript
|
||||
// Connect and send configuration update
|
||||
const ws = new WebSocket('ws://localhost:8888');
|
||||
|
||||
ws.on('open', function() {
|
||||
const configEvent = {
|
||||
kind: 33334,
|
||||
content: "Updated configuration",
|
||||
tags: [
|
||||
["d", relayPubkey],
|
||||
["relay_description", "Updated via API"]
|
||||
],
|
||||
created_at: Math.floor(Date.now() / 1000),
|
||||
pubkey: adminPubkey,
|
||||
// ... add id and sig
|
||||
};
|
||||
|
||||
ws.send(JSON.stringify(["EVENT", configEvent]));
|
||||
});
|
||||
```
|
||||
|
||||
### Backup Strategies
|
||||
|
||||
#### Automated Backup
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# backup-relay.sh
|
||||
DATE=$(date +%Y%m%d_%H%M%S)
|
||||
DB_FILE=$(ls *.nrdb | head -1)
|
||||
BACKUP_DIR="/backup/c-relay"
|
||||
|
||||
mkdir -p $BACKUP_DIR
|
||||
cp $DB_FILE $BACKUP_DIR/relay_backup_$DATE.nrdb
|
||||
gzip $BACKUP_DIR/relay_backup_$DATE.nrdb
|
||||
|
||||
# Cleanup old backups (keep 30 days)
|
||||
find $BACKUP_DIR -name "relay_backup_*.nrdb.gz" -mtime +30 -delete
|
||||
```
|
||||
|
||||
#### Configuration Export
|
||||
```bash
|
||||
# Export configuration events
|
||||
sqlite3 <relay_pubkey>.nrdb "SELECT json_object(
|
||||
'kind', kind,
|
||||
'content', content,
|
||||
'tags', json(tags),
|
||||
'created_at', created_at,
|
||||
'pubkey', pubkey,
|
||||
'sig', sig
|
||||
) FROM events WHERE kind = 33334 ORDER BY created_at;" > config_backup.json
|
||||
```
|
||||
|
||||
### Migration Between Servers
|
||||
```bash
|
||||
# Source server
|
||||
tar czf relay_migration.tar.gz *.nrdb* relay.log
|
||||
|
||||
# Target server
|
||||
tar xzf relay_migration.tar.gz
|
||||
./build/c_relay_x86 # Will detect existing database and continue
|
||||
```

# Deployment Examples
|
||||
|
||||
This directory contains practical deployment examples and scripts for the C Nostr Relay with event-based configuration.
|
||||
|
||||
## Directory Structure
|
||||
|
||||
```
|
||||
examples/deployment/
|
||||
├── README.md # This file
|
||||
├── simple-vps/ # Basic VPS deployment
|
||||
├── nginx-proxy/ # Nginx reverse proxy configurations
|
||||
├── monitoring/ # Monitoring and alerting examples
|
||||
└── backup/ # Backup and recovery scripts
|
||||
```
|
||||
|
||||
## Quick Start Examples
|
||||
|
||||
### 1. Simple VPS Deployment
|
||||
For a basic Ubuntu VPS deployment:
|
||||
```bash
|
||||
cd examples/deployment/simple-vps
|
||||
chmod +x deploy.sh
|
||||
sudo ./deploy.sh
|
||||
```
|
||||
|
||||
### 2. SSL Proxy Setup
|
||||
For nginx reverse proxy with SSL:
|
||||
```bash
|
||||
cd examples/deployment/nginx-proxy
|
||||
chmod +x setup-ssl-proxy.sh
|
||||
sudo ./setup-ssl-proxy.sh -d relay.example.com -e admin@example.com
|
||||
```
|
||||
|
||||
### 3. Monitoring Setup
|
||||
For continuous monitoring:
|
||||
```bash
|
||||
cd examples/deployment/monitoring
|
||||
chmod +x monitor-relay.sh
|
||||
sudo ./monitor-relay.sh -c -e admin@example.com
|
||||
```
|
||||
|
||||
### 4. Backup Setup
|
||||
For automated backups:
|
||||
```bash
|
||||
cd examples/deployment/backup
|
||||
chmod +x backup-relay.sh
|
||||
sudo ./backup-relay.sh -s my-backup-bucket -e admin@example.com
|
||||
```
|
||||
|
||||
## Configuration Examples
|
||||
|
||||
All examples assume the event-based configuration system where:
|
||||
- No config files are needed
|
||||
- Configuration is stored as kind 33334 events in the database
|
||||
- Admin keys are generated on first startup
|
||||
- Database naming uses relay pubkey (`<relay_pubkey>.nrdb`)
|
||||
|
||||
## Security Notes
|
||||
|
||||
- **Save Admin Keys**: All deployment examples emphasize capturing the admin private key on first startup
|
||||
- **Firewall Configuration**: Examples include proper firewall rules
|
||||
- **SSL/TLS**: Production examples include HTTPS configuration
|
||||
- **User Isolation**: Service runs as dedicated `c-relay` system user
|
||||
|
||||

# C Nostr Relay - SystemD Deployment
|
||||
|
||||
This directory contains files for deploying the C Nostr Relay as a systemd service with the new **Event-Based Configuration System**.
|
||||
|
||||
## Overview
|
||||
|
||||
The C Nostr Relay now uses a revolutionary **zero-configuration** approach where all configuration is stored as Nostr events (kind 33334) in the database. No configuration files or command line arguments are needed.
|
||||
|
||||
## Files
|
||||
|
||||
- **`c-relay.service`** - SystemD service unit file
|
||||
- **`install-service.sh`** - Automated installation script
|
||||
- **`uninstall-service.sh`** - Automated uninstall script
|
||||
- **`README.md`** - This documentation
|
||||
|
||||
## Quick Installation
|
||||
|
||||
1. **Build the project:**
|
||||
```bash
|
||||
make clean && make
|
||||
```
|
||||
|
||||
2. **Install as systemd service:**
|
||||
```bash
|
||||
sudo systemd/install-service.sh
|
||||
```
|
||||
|
||||
3. **Start the service:**
|
||||
```bash
|
||||
sudo systemctl start c-relay
|
||||
```
|
||||
|
||||
4. **Check admin keys (IMPORTANT!):**
|
||||
```bash
|
||||
sudo journalctl -u c-relay --since="1 hour ago" | grep "Admin Private Key"
|
||||
```
|
||||
|
||||
## Event-Based Configuration System
|
||||
|
||||
### How It Works
|
||||
|
||||
- **Zero Configuration:** No config files or command line arguments needed
|
||||
- **First-Time Startup:** Automatically generates admin and relay keypairs
|
||||
- **Database Naming:** Creates database as `<relay_pubkey>.nrdb`
|
||||
- **Configuration Storage:** All settings stored as kind 33334 Nostr events
|
||||
- **Real-Time Updates:** Configuration changes applied instantly via WebSocket
|
||||
|
||||
### First Startup
|
||||
|
||||
On first startup, the relay will:
|
||||
|
||||
1. Generate cryptographically secure admin and relay keypairs
|
||||
2. Create database file named with relay pubkey: `<relay_pubkey>.nrdb`
|
||||
3. Create initial configuration event (kind 33334) with default values
|
||||
4. Display admin private key **once** in the logs
|
||||
5. Start WebSocket server listening on port 8888
|
||||
|
||||
### Admin Keys
|
||||
|
||||
⚠️ **CRITICAL:** Save the admin private key displayed during first startup!
|
||||
|
||||
```bash
|
||||
# View first startup logs to get admin private key
|
||||
sudo journalctl -u c-relay --since="1 hour ago" | grep -A 5 "IMPORTANT: SAVE THIS ADMIN PRIVATE KEY"
|
||||
```
|
||||
|
||||
The admin private key is needed to update relay configuration by sending signed kind 33334 events.
|
||||
|
||||
## Configuration Management
|
||||
|
||||
### Viewing Current Configuration
|
||||
|
||||
```bash
|
||||
# Find the database file
|
||||
ls /opt/c-relay/*.nrdb
|
||||
|
||||
# View configuration event
|
||||
sqlite3 /opt/c-relay/<relay_pubkey>.nrdb "SELECT content, tags FROM events WHERE kind = 33334;"
|
||||
```
|
||||
|
||||
### Updating Configuration
|
||||
|
||||
Send a new kind 33334 event to the relay via WebSocket:
|
||||
|
||||
1. Create new configuration event with updated values
|
||||
2. Sign with admin private key
|
||||
3. Send via WebSocket to relay
|
||||
4. Relay automatically applies changes to running system
|
||||
|
||||
## Service Management
|
||||
|
||||
### Basic Commands
|
||||
|
||||
```bash
|
||||
# Start service
|
||||
sudo systemctl start c-relay
|
||||
|
||||
# Stop service
|
||||
sudo systemctl stop c-relay
|
||||
|
||||
# Restart service
|
||||
sudo systemctl restart c-relay
|
||||
|
||||
# Enable auto-start on boot
|
||||
sudo systemctl enable c-relay
|
||||
|
||||
# Check status
|
||||
sudo systemctl status c-relay
|
||||
|
||||
# View logs (live)
|
||||
sudo journalctl -u c-relay -f
|
||||
|
||||
# View recent logs
|
||||
sudo journalctl -u c-relay --since="1 hour ago"
|
||||
```
|
||||
|
||||
### Log Analysis
|
||||
|
||||
```bash
|
||||
# Check for successful startup
|
||||
sudo journalctl -u c-relay | grep "First-time startup sequence completed"
|
||||
|
||||
# Find admin keys
|
||||
sudo journalctl -u c-relay | grep "Admin Private Key"
|
||||
|
||||
# Check configuration updates
|
||||
sudo journalctl -u c-relay | grep "Configuration updated via kind 33334"
|
||||
|
||||
# Monitor real-time activity
|
||||
sudo journalctl -u c-relay -f | grep -E "(INFO|SUCCESS|ERROR)"
|
||||
```
|
||||
|
||||
## File Locations
|
||||
|
||||
After installation:
|
||||
|
||||
- **Binary:** `/opt/c-relay/c_relay_x86`
|
||||
- **Database:** `/opt/c-relay/<relay_pubkey>.nrdb` (created automatically)
|
||||
- **Service File:** `/etc/systemd/system/c-relay.service`
|
||||
- **User:** `c-relay` (system user created automatically)
|
||||
|
||||
## Security Features
|
||||
|
||||
The systemd service includes security hardening:
|
||||
|
||||
- Runs as dedicated system user `c-relay`
|
||||
- `NoNewPrivileges=true`
|
||||
- `ProtectSystem=strict`
|
||||
- `ProtectHome=true`
|
||||
- `PrivateTmp=true`
|
||||
- Limited address families (IPv4/IPv6 only)
|
||||
- Resource limits (file descriptors, processes)
|
||||
|
||||
## Network Configuration
|
||||
|
||||
- **Default Port:** 8888 (WebSocket)
|
||||
- **Protocol:** WebSocket with Nostr message format
|
||||
- **Configuration:** Port configurable via kind 33334 events (no restart needed)
|
||||
|
||||
## Backup and Migration
|
||||
|
||||
### Backup
|
||||
|
||||
The database file contains everything:
|
||||
|
||||
```bash
|
||||
# Backup database file
|
||||
sudo cp /opt/c-relay/*.nrdb /backup/location/
|
||||
|
||||
# The .nrdb file contains:
|
||||
# - All Nostr events
|
||||
# - Configuration events (kind 33334)
|
||||
# - Relay keys and settings
|
||||
```
|
||||
|
||||
### Migration
|
||||
|
||||
To migrate to new server:
|
||||
|
||||
1. Copy `.nrdb` file to new server's `/opt/c-relay/` directory
|
||||
2. Install service with `install-service.sh`
|
||||
3. Start service - it will automatically detect existing configuration
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Service Won't Start
|
||||
|
||||
```bash
|
||||
# Check service status
|
||||
sudo systemctl status c-relay
|
||||
|
||||
# Check logs for errors
|
||||
sudo journalctl -u c-relay --no-pager
|
||||
|
||||
# Check if binary exists and is executable
|
||||
ls -la /opt/c-relay/c_relay_x86
|
||||
|
||||
# Check permissions
|
||||
sudo -u c-relay ls -la /opt/c-relay/
|
||||
```
|
||||
|
||||
### Database Issues
|
||||
|
||||
```bash
|
||||
# Check if database file exists
|
||||
ls -la /opt/c-relay/*.nrdb*
|
||||
|
||||
# Check database integrity
|
||||
sqlite3 /opt/c-relay/*.nrdb "PRAGMA integrity_check;"
|
||||
|
||||
# View database schema
|
||||
sqlite3 /opt/c-relay/*.nrdb ".schema"
|
||||
```
|
||||
|
||||
### Configuration Issues
|
||||
|
||||
```bash
|
||||
# Check if configuration event exists
|
||||
sqlite3 /opt/c-relay/*.nrdb "SELECT COUNT(*) FROM events WHERE kind = 33334;"
|
||||
|
||||
# View configuration event
|
||||
sqlite3 /opt/c-relay/*.nrdb "SELECT id, created_at, LENGTH(tags) FROM events WHERE kind = 33334;"
|
||||
```
|
||||
|
||||
## Uninstallation
|
||||
|
||||
```bash
|
||||
sudo systemd/uninstall-service.sh
|
||||
```
|
||||
|
||||
The uninstall script will:
|
||||
- Stop and disable the service
|
||||
- Remove service file
|
||||
- Optionally remove installation directory and data
|

|

## Support
|
||||
|
||||
For issues with the event-based configuration system:
|
||||
|
||||
1. Check service logs: `sudo journalctl -u c-relay -f`
|
||||
2. Verify database integrity
|
||||
3. Ensure admin private key is saved securely
|
||||
4. Check WebSocket connectivity on port 8888
|
||||
|
||||
The relay is designed to be zero-maintenance once deployed. All configuration is managed through Nostr events, enabling dynamic updates without server access.
