# ADR-022: Multiple Syndication Format Support
|
||||
|
||||
## Status
|
||||
Proposed
|
||||
|
||||
## Context
|
||||
StarPunk currently provides RSS 2.0 feed generation using the feedgen library. The IndieWeb community and modern feed readers increasingly support additional syndication formats:
|
||||
- ATOM feeds (RFC 4287) - W3C/IETF standard XML format
|
||||
- JSON Feed (v1.1) - Modern JSON-based format gaining adoption
|
||||
- Microformats2 - Already partially implemented for IndieWeb parsing
|
||||
|
||||
Multiple syndication formats increase content reach and client compatibility.
|
||||
|
||||
## Decision
|
||||
Implement ATOM and JSON Feed support alongside existing RSS 2.0, maintaining all three formats in parallel.
|
||||
|
||||
## Rationale
|
||||
1. **Low Implementation Complexity**: The feedgen library already supports ATOM generation with minimal code changes
|
||||
2. **JSON Feed Simplicity**: JSON structure maps directly to our Note model, easier than XML
|
||||
3. **Standards Alignment**: Both formats are well-specified and stable
|
||||
4. **User Choice**: Different clients prefer different formats
|
||||
5. **Minimal Maintenance**: Once implemented, feed formats rarely change
|
||||
|
||||
## Consequences
|
||||
### Positive
|
||||
- Broader client compatibility
|
||||
- Better IndieWeb ecosystem integration
|
||||
- Leverages existing feedgen dependency for ATOM
|
||||
- JSON Feed provides modern alternative to XML
|
||||
|
||||
### Negative
|
||||
- Three feed endpoints to maintain
|
||||
- Slightly increased test surface
|
||||
- Additional routes in API
|
||||
|
||||
## Alternatives Considered
|
||||
1. **Single Universal Format**: Rejected - different clients have different preferences
|
||||
2. **Content Negotiation**: Too complex for minimal benefit
|
||||
3. **Plugin System**: Over-engineering for 3 stable formats
|
||||
|
||||
## Implementation Approach
|
||||
1. ATOM: Use feedgen's built-in ATOM support (5-10 lines different from RSS)
|
||||
2. JSON Feed: Direct serialization from Note models (~50 lines)
|
||||
3. Routes: `/feed.xml` (RSS), `/feed.atom` (ATOM), `/feed.json` (JSON)
|
||||
|
||||
## Effort Estimate
|
||||
- ATOM Feed: 2-4 hours (mostly testing)
|
||||
- JSON Feed: 4-6 hours (new serialization logic)
|
||||
- Tests & Documentation: 2-3 hours
|
||||
- Total: 8-13 hours

# ADR-023: Strict Microformats2 Compliance
|
||||
|
||||
## Status
|
||||
Proposed
|
||||
|
||||
## Context
|
||||
StarPunk currently implements basic microformats2 markup:
|
||||
- h-entry on note articles
|
||||
- e-content for note content
|
||||
- dt-published for timestamps
|
||||
- u-url for permalinks
|
||||
|
||||
"Strict" microformats2 compliance would add comprehensive markup for full IndieWeb interoperability, enabling better parsing by readers, Webmention receivers, and IndieWeb tools.
|
||||
|
||||
## Decision
|
||||
Enhance existing templates with complete microformats2 vocabulary, focusing on h-entry, h-card, and h-feed structures.
|
||||
|
||||
## Rationale
|
||||
1. **Core IndieWeb Requirement**: Microformats2 is fundamental to IndieWeb data exchange
|
||||
2. **Template-Only Changes**: No backend modifications required
|
||||
3. **Progressive Enhancement**: Adds semantic value without breaking existing functionality
|
||||
4. **Standards Maturity**: Microformats2 spec is stable and well-documented
|
||||
5. **Testing Tools Available**: Validators exist for compliance verification
|
||||
|
||||
## Consequences
|
||||
### Positive
|
||||
- Full IndieWeb parser compatibility
|
||||
- Better social reader integration
|
||||
- Improved SEO through semantic markup
|
||||
- Enables future Webmention support (v1.3.0)
|
||||
|
||||
### Negative
|
||||
- More complex HTML templates
|
||||
- Careful CSS selector management needed
|
||||
- Testing requires microformats2 parser
|
||||
|
||||
## Alternatives Considered
|
||||
1. **Minimal Compliance**: Current state - rejected as incomplete for IndieWeb tools
|
||||
2. **Microdata/RDFa**: Not IndieWeb standard, adds complexity
|
||||
3. **JSON-LD**: Additional complexity, not IndieWeb native
|
||||
|
||||
## Implementation Scope
|
||||
### Required Markup
|
||||
1. **h-entry** (complete):
|
||||
- p-name (title extraction)
|
||||
- p-summary (excerpt)
|
||||
- p-category (when tags added)
|
||||
- p-author with embedded h-card
|
||||
|
||||
2. **h-card** (author):
|
||||
- p-name (author name)
|
||||
- u-url (author URL)
|
||||
- u-photo (avatar, optional)
|
||||
|
||||
3. **h-feed** (index pages):
|
||||
- p-name (feed title)
|
||||
- p-author (feed author)
|
||||
- Nested h-entry items
|
||||
|
||||
### Template Updates Required
|
||||
- `/templates/base.html` - Add h-card in header
|
||||
- `/templates/index.html` - Add h-feed wrapper
|
||||
- `/templates/note.html` - Complete h-entry properties
|
||||
- `/templates/partials/note_summary.html` - Create for consistent h-entry
|
||||
|
||||
## Effort Estimate
|
||||
- Template Analysis: 2-3 hours
|
||||
- Markup Implementation: 4-6 hours
|
||||
- CSS Compatibility Check: 1-2 hours
|
||||
- Testing with mf2 parser: 2-3 hours
|
||||
- Documentation: 1-2 hours
|
||||
- Total: 10-16 hours

# ADR-052: Configuration System Architecture
|
||||
|
||||
## Status
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
StarPunk v1.1.1 "Polish" introduces several configurable features to improve production readiness and user experience. Currently, configuration values are hardcoded throughout the application, making customization difficult. We need a consistent, simple approach to configuration management that:
|
||||
|
||||
1. Maintains backward compatibility
|
||||
2. Provides sensible defaults
|
||||
3. Follows Python best practices
|
||||
4. Minimizes complexity
|
||||
5. Supports environment-based configuration
|
||||
|
||||
## Decision
|
||||
We will implement a centralized configuration system using environment variables with fallback defaults, managed through a single configuration module.
|
||||
|
||||
### Configuration Architecture
|
||||
|
||||
```
|
||||
Environment Variables (highest priority)
|
||||
↓
|
||||
Configuration File (optional, .env)
|
||||
↓
|
||||
Default Values (in code)
|
||||
```
|
||||
|
||||
### Configuration Module Structure
|
||||
|
||||
Location: `starpunk/config.py`
|
||||
|
||||
Categories:
|
||||
1. **Search Configuration**
|
||||
- `SEARCH_ENABLED`: bool (default: True)
|
||||
- `SEARCH_TITLE_LENGTH`: int (default: 100)
|
||||
- `SEARCH_HIGHLIGHT_CLASS`: str (default: "highlight")
|
||||
- `SEARCH_MIN_SCORE`: float (default: 0.0)
|
||||
|
||||
2. **Performance Configuration**
|
||||
- `PERF_MONITORING_ENABLED`: bool (default: False)
|
||||
- `PERF_SLOW_QUERY_THRESHOLD`: float (default: 1.0 seconds)
|
||||
- `PERF_LOG_QUERIES`: bool (default: False)
|
||||
- `PERF_MEMORY_TRACKING`: bool (default: False)
|
||||
|
||||
3. **Database Configuration**
|
||||
- `DB_CONNECTION_POOL_SIZE`: int (default: 5)
|
||||
- `DB_CONNECTION_TIMEOUT`: float (default: 10.0)
|
||||
- `DB_WAL_MODE`: bool (default: True)
|
||||
- `DB_BUSY_TIMEOUT`: int (default: 5000 ms)
|
||||
|
||||
4. **Logging Configuration**
|
||||
- `LOG_LEVEL`: str (default: "INFO")
|
||||
- `LOG_FORMAT`: str (default: structured JSON)
|
||||
- `LOG_FILE_PATH`: str (default: None)
|
||||
- `LOG_ROTATION`: bool (default: False)
|
||||
|
||||
5. **Production Configuration**
|
||||
- `SESSION_TIMEOUT`: int (default: 86400 seconds)
|
||||
- `HEALTH_CHECK_DETAILED`: bool (default: False)
|
||||
- `ERROR_DETAILS_IN_RESPONSE`: bool (default: False)
|
||||
|
||||
### Implementation Pattern
|
||||
|
||||
```python
|
||||
# starpunk/config.py
|
||||
import os
|
||||
from typing import Any, Optional
|
||||
|
||||
class Config:
|
||||
"""Centralized configuration management"""
|
||||
|
||||
@staticmethod
|
||||
def get_bool(key: str, default: bool = False) -> bool:
|
||||
"""Get boolean configuration value"""
|
||||
value = os.environ.get(key, "").lower()
|
||||
if value in ("true", "1", "yes", "on"):
|
||||
return True
|
||||
elif value in ("false", "0", "no", "off"):
|
||||
return False
|
||||
return default
|
||||
|
||||
@staticmethod
|
||||
def get_int(key: str, default: int) -> int:
|
||||
"""Get integer configuration value"""
|
||||
try:
|
||||
return int(os.environ.get(key, default))
|
||||
except (ValueError, TypeError):
|
||||
return default
|
||||
|
||||
@staticmethod
|
||||
def get_float(key: str, default: float) -> float:
|
||||
"""Get float configuration value"""
|
||||
try:
|
||||
return float(os.environ.get(key, default))
|
||||
except (ValueError, TypeError):
|
||||
return default
|
||||
|
||||
@staticmethod
|
||||
def get_str(key: str, default: str = "") -> str:
|
||||
"""Get string configuration value"""
|
||||
return os.environ.get(key, default)
|
||||
|
||||
# Configuration instances
|
||||
SEARCH_ENABLED = Config.get_bool("STARPUNK_SEARCH_ENABLED", True)
|
||||
SEARCH_TITLE_LENGTH = Config.get_int("STARPUNK_SEARCH_TITLE_LENGTH", 100)
|
||||
# ... etc
|
||||
```
|
||||
|
||||
### Environment Variable Naming Convention
|
||||
|
||||
All StarPunk environment variables are prefixed with `STARPUNK_` to avoid conflicts:
|
||||
- `STARPUNK_SEARCH_ENABLED`
|
||||
- `STARPUNK_PERF_MONITORING_ENABLED`
|
||||
- `STARPUNK_DB_CONNECTION_POOL_SIZE`
|
||||
- etc.
|
||||
|
||||
## Rationale
|
||||
|
||||
### Why Environment Variables?
|
||||
1. **Standard Practice**: Follows 12-factor app methodology
|
||||
2. **Container Friendly**: Works well with Docker/Kubernetes
|
||||
3. **No Dependencies**: Built into Python stdlib
|
||||
4. **Security**: Sensitive values not in code
|
||||
5. **Simple**: No complex configuration parsing
|
||||
|
||||
### Why Not Alternative Approaches?
|
||||
|
||||
**YAML/TOML/INI Files**:
|
||||
- Adds parsing complexity
|
||||
- Requires file management
|
||||
- Not as container-friendly
|
||||
- Additional dependency
|
||||
|
||||
**Database Configuration**:
|
||||
- Circular dependency (need config to connect to DB)
|
||||
- Makes deployment more complex
|
||||
- Not suitable for bootstrap configuration
|
||||
|
||||
**Python Config Files**:
|
||||
- Security risk if user-editable
|
||||
- Import complexity
|
||||
- Not standard practice
|
||||
|
||||
### Why Centralized Module?
|
||||
1. **Single Source**: All configuration in one place
|
||||
2. **Type Safety**: Helper methods ensure correct types
|
||||
3. **Documentation**: Self-documenting defaults
|
||||
4. **Testing**: Easy to mock for tests
|
||||
5. **Validation**: Can add validation logic centrally
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
1. **Backward Compatible**: All existing deployments continue working with defaults
|
||||
2. **Production Ready**: Ops teams can configure without code changes
|
||||
3. **Simple Implementation**: ~100 lines of code
|
||||
4. **Testable**: Easy to test different configurations
|
||||
5. **Documented**: Configuration options clear in one file
|
||||
6. **Flexible**: Can override any setting via environment
|
||||
|
||||
### Negative
|
||||
1. **Environment Pollution**: Many environment variables in production
|
||||
2. **No Validation**: Invalid values fall back to defaults silently
|
||||
3. **No Hot Reload**: Requires restart to apply changes
|
||||
4. **Limited Types**: Only primitive types supported
|
||||
|
||||
### Mitigations
|
||||
1. Use `.env` files for local development
|
||||
2. Add startup configuration validation
|
||||
3. Log configuration values at startup (non-sensitive only)
|
||||
4. Document all configuration options clearly
|
||||
|
||||
## Alternatives Considered
|
||||
|
||||
### 1. Pydantic Settings
|
||||
**Pros**: Type validation, .env support, modern
|
||||
**Cons**: New dependency, overengineered for our needs
|
||||
**Decision**: Too complex for v1.1.1 patch release
|
||||
|
||||
### 2. Click Configuration
|
||||
**Pros**: Already using Click, integrated CLI options
|
||||
**Cons**: CLI args not suitable for all config, complex precedence
|
||||
**Decision**: Keep CLI and config separate
|
||||
|
||||
### 3. ConfigParser (INI files)
|
||||
**Pros**: Python stdlib, familiar format
|
||||
**Cons**: File management complexity, not container-native
|
||||
**Decision**: Environment variables are simpler
|
||||
|
||||
### 4. No Configuration System
|
||||
**Pros**: Simplest possible
|
||||
**Cons**: No production flexibility, poor UX
|
||||
**Decision**: v1.1.1 specifically targets production readiness
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
1. Configuration module loads at import time
|
||||
2. Values are immutable after startup
|
||||
3. Invalid values log warnings but use defaults
|
||||
4. Sensitive values (tokens, keys) never logged
|
||||
5. Configuration documented in deployment guide
|
||||
6. Example `.env.example` file provided
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
1. Unit tests mock environment variables
|
||||
2. Integration tests verify default behavior
|
||||
3. Configuration validation tests
|
||||
4. Performance impact tests (configuration overhead)
|
||||
|
||||
## Migration Path
|
||||
|
||||
No migration required - all configuration has sensible defaults that match current behavior.

# ADR-053: Performance Monitoring Strategy
|
||||
|
||||
## Status
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
StarPunk v1.1.1 introduces performance monitoring to help operators understand system behavior in production. Currently, we have no visibility into:
|
||||
- Database query performance
|
||||
- Memory usage patterns
|
||||
- Request processing times
|
||||
- Bottlenecks and slow operations
|
||||
|
||||
We need a lightweight, zero-dependency monitoring solution that provides actionable insights without impacting performance.
|
||||
|
||||
## Decision
|
||||
Implement a built-in performance monitoring system using Python's standard library, with optional detailed tracking controlled by configuration.
|
||||
|
||||

|
||||
|
||||
### Core Components
|
||||
|
||||
#### 1. Metrics Collector
|
||||
Location: `starpunk/monitoring/collector.py`
|
||||
|
||||
Responsibilities:
|
||||
- Collect timing data
|
||||
- Track memory usage
|
||||
- Store recent metrics in memory
|
||||
- Provide aggregation functions
|
||||
|
||||
Data Structure:
|
||||
```python
|
||||
@dataclass
|
||||
class Metric:
|
||||
timestamp: float
|
||||
category: str # "db", "http", "function"
|
||||
operation: str # specific operation name
|
||||
duration: float # in seconds
|
||||
metadata: dict # additional context
|
||||
```
|
||||
|
||||
#### 2. Database Performance Tracking
|
||||
Location: `starpunk/monitoring/db_monitor.py`
|
||||
|
||||
Features:
|
||||
- Query execution timing
|
||||
- Slow query detection
|
||||
- Query pattern analysis
|
||||
- Connection pool monitoring
|
||||
|
||||
Implementation via SQLite callbacks:
|
||||
```python
|
||||
# Wrap database operations
|
||||
with monitor.track_query("SELECT", "notes"):
|
||||
cursor.execute(query)
|
||||
```
|
||||
|
||||
#### 3. Memory Tracking
|
||||
Location: `starpunk/monitoring/memory.py`
|
||||
|
||||
Track:
|
||||
- Process memory (RSS)
|
||||
- Memory growth over time
|
||||
- Per-request memory delta
|
||||
- Memory high water mark
|
||||
|
||||
Uses `resource` module (stdlib).
|
||||
|
||||
#### 4. Request Performance
|
||||
Location: `starpunk/monitoring/http.py`
|
||||
|
||||
Track:
|
||||
- Request processing time
|
||||
- Response size
|
||||
- Status code distribution
|
||||
- Slowest endpoints
|
||||
|
||||
#### 5. Admin Dashboard
|
||||
Location: `/admin/performance`
|
||||
|
||||
Display:
|
||||
- Real-time metrics (last 15 minutes)
|
||||
- Slow query log
|
||||
- Memory usage graph
|
||||
- Endpoint performance table
|
||||
- Database statistics
|
||||
|
||||
### Data Retention
|
||||
|
||||
In-memory circular buffer approach:
|
||||
- Last 1000 metrics retained
|
||||
- Automatic old data eviction
|
||||
- No persistent storage (privacy/simplicity)
|
||||
- Reset on restart
|
||||
|
||||
### Performance Overhead
|
||||
|
||||
Target: <1% overhead when enabled
|
||||
|
||||

- Sampling for high-frequency operations
|
||||
- Lazy computation of aggregates
|
||||
- Minimal memory footprint (1MB max)
|
||||
- Conditional compilation via config
|
||||
|
||||
## Rationale
|
||||
|
||||
### Why Built-in Monitoring?
|
||||
1. **Zero Dependencies**: Uses only Python stdlib
|
||||
2. **Privacy**: No external services
|
||||
3. **Simplicity**: No complex setup
|
||||
4. **Integrated**: Direct access to internals
|
||||
5. **Lightweight**: Minimal overhead
|
||||
|
||||
### Why Not External Tools?
|
||||
|
||||
**Prometheus/Grafana**:
|
||||
- Requires external services
|
||||
- Complex setup
|
||||
- Overkill for single-user system
|
||||
|
||||
**APM Services** (New Relic, DataDog):
|
||||
- Privacy concerns
|
||||
- Subscription costs
|
||||
- Network dependency
|
||||
- Too heavy for our needs
|
||||
|
||||
**OpenTelemetry**:
|
||||
- Large dependency
|
||||
- Complex configuration
|
||||
- Designed for distributed systems
|
||||
|
||||
### Design Principles
|
||||
|
||||
1. **Opt-in**: Disabled by default
|
||||
2. **Lightweight**: Minimal resource usage
|
||||
3. **Actionable**: Focus on useful metrics
|
||||
4. **Temporary**: No permanent storage
|
||||
5. **Private**: No external data transmission
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
1. **Production Visibility**: Understand behavior under load
|
||||
2. **Performance Debugging**: Identify bottlenecks quickly
|
||||
3. **No Dependencies**: Pure Python solution
|
||||
4. **Privacy Preserving**: Data stays local
|
||||
5. **Simple Deployment**: No additional services
|
||||
|
||||
### Negative
|
||||
1. **Limited History**: Only recent data available
|
||||
2. **Memory Usage**: ~1MB for metrics buffer
|
||||
3. **No Alerting**: Manual monitoring required
|
||||
4. **Single Node**: No distributed tracing
|
||||
|
||||
### Mitigations
|
||||
1. Export capability for external tools
|
||||
2. Configurable buffer size
|
||||
3. Webhook support for alerts (future)
|
||||
4. Focus on most valuable metrics
|
||||
|
||||
## Alternatives Considered
|
||||
|
||||
### 1. Logging-based Monitoring
|
||||
**Approach**: Parse performance data from logs
|
||||
**Pros**: Simple, no new code
|
||||
**Cons**: Log parsing complexity, no real-time view
|
||||
**Decision**: Dedicated monitoring is cleaner
|
||||
|
||||
### 2. External Monitoring Service
|
||||
**Approach**: Use service like Sentry
|
||||
**Pros**: Full-featured, alerting included
|
||||
**Cons**: Privacy, cost, complexity
|
||||
**Decision**: Violates self-hosted principle
|
||||
|
||||
### 3. Prometheus Exporter
|
||||
**Approach**: Expose /metrics endpoint
|
||||
**Pros**: Standard, good tooling
|
||||
**Cons**: Requires Prometheus setup
|
||||
**Decision**: Too complex for target users
|
||||
|
||||
### 4. No Monitoring
|
||||
**Approach**: Rely on logs and external tools
|
||||
**Pros**: Simplest
|
||||
**Cons**: Poor production visibility
|
||||
**Decision**: v1.1.1 specifically targets production readiness
|
||||
|
||||

|
||||
- Connection acquisition/release
|
||||
- Transaction duration
|
||||
- Migration execution
|
||||
|
||||
2. **HTTP Layer**
|
||||
- Middleware wraps all requests
|
||||
- Per-endpoint timing
|
||||
- Static file serving
|
||||
- Error handling
|
||||
|
||||
3. **Core Functions**
|
||||
- Note creation/update
|
||||
- Search operations
|
||||
- RSS generation
|
||||
- Authentication flow
|
||||
|

```python
|
||||
# All under STARPUNK_PERF_* prefix
|
||||
MONITORING_ENABLED = False # Master switch
|
||||
SLOW_QUERY_THRESHOLD = 1.0 # seconds
|
||||
LOG_QUERIES = False # Log all queries
|
||||
MEMORY_TRACKING = False # Track memory usage
|
||||
SAMPLE_RATE = 1.0 # 1.0 = all, 0.1 = 10%
|
||||
BUFFER_SIZE = 1000 # Number of metrics
|
||||
DASHBOARD_ENABLED = True # Enable web UI
|
||||
```
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
1. **Unit Tests**: Mock collectors, verify metrics
|
||||
2. **Integration Tests**: End-to-end monitoring flow
|
||||
3. **Performance Tests**: Verify low overhead
|
||||
4. **Load Tests**: Behavior under stress
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. Dashboard requires admin authentication
|
||||
2. No sensitive data in metrics
|
||||
3. No external data transmission
|
||||
4. Metrics cleared on logout
|
||||
5. Rate limiting on dashboard endpoint
|
||||
|
||||
## Migration Path
|
||||
|
||||
No migration required - monitoring is opt-in via configuration.
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
v1.2.0 and beyond:
|
||||
- Metric export (CSV/JSON)
|
||||
- Alert thresholds
|
||||
- Historical trending
|
||||
- Custom metric points
|
||||
- Plugin architecture

# ADR-054: Structured Logging Architecture
|
||||
|
||||
## Status
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
StarPunk currently uses print statements and basic logging without structure. For production deployments, we need:
|
||||
- Consistent log formatting
|
||||
- Appropriate log levels
|
||||
- Structured data for parsing
|
||||
- Correlation IDs for request tracking
|
||||
- Performance-conscious logging
|
||||
|
||||
We need a logging architecture that is simple, follows Python best practices, and provides production-grade observability.
|
||||
|
||||
## Decision
|
||||
Implement structured logging using Python's built-in `logging` module with JSON formatting and contextual information.
|
||||
|
||||
### Logging Architecture
|
||||
|
||||
```
|
||||
Application Code
|
||||
↓
|
||||
Logger Interface → Filters → Formatters → Handlers → Output
|
||||
↑ ↓
|
||||
Context Injection (stdout/file)
|
||||
```
|
||||
|
||||
### Log Levels
|
||||
|
||||
Following standard Python/syslog levels:
|
||||
|
||||
| Level | Value | Usage |
|
||||
|-------|-------|-------|
|
||||
| CRITICAL | 50 | System failures requiring immediate attention |
|
||||
| ERROR | 40 | Errors that need investigation |
|
||||
| WARNING | 30 | Unexpected conditions that might cause issues |
|
||||
| INFO | 20 | Normal operation events |
|
||||
| DEBUG | 10 | Detailed diagnostic information |
|
||||
|
||||
### Log Structure
|
||||
|
||||
JSON format for production, human-readable for development:
|
||||
|
||||
```json
|
||||
{
|
||||
"timestamp": "2025-11-25T10:30:45.123Z",
|
||||
"level": "INFO",
|
||||
"logger": "starpunk.micropub",
|
||||
"message": "Note created",
|
||||
"request_id": "a1b2c3d4",
|
||||
"user": "alice@example.com",
|
||||
"context": {
|
||||
"note_id": 123,
|
||||
"slug": "my-note",
|
||||
"word_count": 42
|
||||
},
|
||||
"performance": {
|
||||
"duration_ms": 45
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Logger Hierarchy
|
||||
|
||||
```
|
||||
starpunk (root logger)
|
||||
├── starpunk.auth # Authentication/authorization
|
||||
├── starpunk.micropub # Micropub endpoint
|
||||
├── starpunk.database # Database operations
|
||||
├── starpunk.search # Search functionality
|
||||
├── starpunk.web # Web interface
|
||||
├── starpunk.rss # RSS generation
|
||||
├── starpunk.monitoring # Performance monitoring
|
||||
└── starpunk.migration # Database migrations
|
||||
```
|
||||
|
||||
### Implementation Pattern
|
||||
|
||||
```python
|
||||
# starpunk/logging.py
|
||||
import logging
|
||||
import json
|
||||
import sys
|
||||
from datetime import datetime
|
||||
from contextvars import ContextVar
|
||||
|
||||
# Request context for correlation
|
||||
request_id: ContextVar[str] = ContextVar('request_id', default='')
|
||||
|
||||
class StructuredFormatter(logging.Formatter):
|
||||
"""JSON formatter for structured logging"""
|
||||
|
||||
def format(self, record):
|
||||
log_obj = {
|
||||
'timestamp': datetime.utcnow().isoformat() + 'Z',
|
||||
'level': record.levelname,
|
||||
'logger': record.name,
|
||||
'message': record.getMessage(),
|
||||
'request_id': request_id.get()
|
||||
}
|
||||
|
||||
# Add extra fields
|
||||
if hasattr(record, 'context'):
|
||||
log_obj['context'] = record.context
|
||||
|
||||
if hasattr(record, 'performance'):
|
||||
log_obj['performance'] = record.performance
|
||||
|
||||
# Add exception info if present
|
||||
if record.exc_info:
|
||||
log_obj['exception'] = self.formatException(record.exc_info)
|
||||
|
||||
return json.dumps(log_obj)
|
||||
|
||||
def setup_logging(level='INFO', format_type='json'):
|
||||
"""Configure logging for the application"""
|
||||
root_logger = logging.getLogger('starpunk')
|
||||
root_logger.setLevel(level)
|
||||
|
||||
handler = logging.StreamHandler(sys.stdout)
|
||||
|
||||
if format_type == 'json':
|
||||
formatter = StructuredFormatter()
|
||||
else:
|
||||
# Human-readable for development
|
||||
formatter = logging.Formatter(
|
||||
'%(asctime)s - %(name)s - %(levelname)s - %(message)s'
|
||||
)
|
||||
|
||||
handler.setFormatter(formatter)
|
||||
root_logger.addHandler(handler)
|
||||
|
||||
return root_logger
|
||||
|
||||
# Usage pattern
|
||||
logger = logging.getLogger('starpunk.micropub')
|
||||
|
||||
def create_note(content, user):
|
||||
logger.info(
|
||||
"Creating note",
|
||||
extra={
|
||||
'context': {
|
||||
'user': user,
|
||||
'content_length': len(content)
|
||||
}
|
||||
}
|
||||
)
|
||||
# ... implementation
|
||||
```
|
||||
|
||||
### What to Log
|
||||
|
||||
#### Always Log (INFO+)
|
||||
- Authentication attempts (success/failure)
|
||||
- Note CRUD operations
|
||||
- Configuration changes
|
||||
- Startup/shutdown
|
||||
- External API calls
|
||||
- Migration execution
|
||||
- Search queries
|
||||
|
||||
#### Error Conditions (ERROR)
|
||||
- Database connection failures
|
||||
- Invalid Micropub requests
|
||||
- Authentication failures
|
||||
- File system errors
|
||||
- Configuration errors
|
||||
|
||||
#### Warnings (WARNING)
|
||||
- Slow queries
|
||||
- High memory usage
|
||||
- Deprecated feature usage
|
||||
- Missing optional configuration
|
||||
- FTS5 unavailability
|
||||
|
||||
#### Debug Information (DEBUG)
|
||||
- SQL queries executed
|
||||
- Request/response bodies
|
||||
- Template rendering details
|
||||
- Cache operations
|
||||
- Detailed timing data
|
||||
|
||||
### What NOT to Log
|
||||
- Passwords or tokens
|
||||
- Full note content (unless debug)
|
||||
- Personal information (PII)
|
||||
- Request headers with auth
|
||||
- Database connection strings
|
||||
|
||||
### Performance Considerations
|
||||
|
||||
1. **Lazy Evaluation**: Use lazy % formatting
|
||||
```python
|
||||
logger.debug("Processing note %s", note_id) # Good
|
||||
logger.debug(f"Processing note {note_id}") # Bad
|
||||
```
|
||||
|
||||
2. **Level Checking**: Check before expensive operations
|
||||
```python
|
||||
if logger.isEnabledFor(logging.DEBUG):
|
||||
logger.debug("Data: %s", expensive_serialization())
|
||||
```
|
||||
|
||||
3. **Async Logging**: For high-volume scenarios (future)
|
||||
|
||||
4. **Sampling**: For very frequent operations
|
||||
```python
|
||||
if random.random() < 0.1: # Log 10%
|
||||
logger.debug("High frequency operation")
|
||||
```
|
||||
|
||||
## Rationale
|
||||
|
||||
### Why Standard Logging Module?
|
||||
1. **No Dependencies**: Built into Python
|
||||
2. **Industry Standard**: Well understood
|
||||
3. **Flexible**: Handlers, formatters, filters
|
||||
4. **Battle-tested**: Proven in production
|
||||
5. **Integration**: Works with existing tools
|
||||
|
||||
### Why JSON Format?
|
||||
1. **Parseable**: Easy for log aggregators
|
||||
2. **Structured**: Consistent field access
|
||||
3. **Flexible**: Can add fields without breaking
|
||||
4. **Standard**: Widely supported
|
||||
|
||||
### Why Not Alternatives?
|
||||
|
||||
**structlog**:
|
||||
- Additional dependency
|
||||
- More complex API
|
||||
- Overkill for our needs
|
||||
|
||||
**loguru**:
|
||||
- Third-party dependency
|
||||
- Non-standard API
|
||||
- Not necessary for our scale
|
||||
|
||||
**Print statements**:
|
||||
- No levels
|
||||
- No structure
|
||||
- No filtering
|
||||
- Not production-ready
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
1. **Production Ready**: Professional logging
|
||||
2. **Debuggable**: Rich context in logs
|
||||
3. **Parseable**: Integration with log tools
|
||||
4. **Performant**: Minimal overhead
|
||||
5. **Configurable**: Adjust without code changes
|
||||
6. **Correlatable**: Request tracking via IDs
|
||||
|
||||
### Negative
|
||||
1. **Verbosity**: More code for logging
|
||||
2. **Learning**: Developers must understand levels
|
||||
3. **Size**: JSON logs are larger than plain text
|
||||
4. **Complexity**: More setup than prints
|
||||
|
||||
### Mitigations
|
||||
1. Provide logging utilities/helpers
|
||||
2. Document logging guidelines
|
||||
3. Use log rotation for size management
|
||||
4. Create developer-friendly formatter option
|
||||
|
||||
## Alternatives Considered
|
||||
|
||||
### 1. Continue with Print Statements
|
||||
**Pros**: Simplest possible
|
||||
**Cons**: Not production-ready
|
||||
**Decision**: Inadequate for production
|
||||
|
||||
### 2. Custom Logging Solution
|
||||
**Pros**: Exactly what we need
|
||||
**Cons**: Reinventing the wheel
|
||||
**Decision**: Standard library is sufficient
|
||||
|
||||
### 3. External Logging Service
|
||||
**Pros**: No local storage needed
|
||||
**Cons**: Privacy, dependency, cost
|
||||
**Decision**: Conflicts with self-hosted philosophy
|
||||
|
||||
### 4. Syslog Integration
|
||||
**Pros**: Standard Unix logging
|
||||
**Cons**: Platform-specific, complexity
|
||||
**Decision**: Can add as handler if needed
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
### Bootstrap Logging
|
||||
```python
|
||||
# Application startup
|
||||
import logging
|
||||
from starpunk.logging import setup_logging
|
||||
|
||||
# Configure based on environment
|
||||
if os.environ.get('STARPUNK_ENV') == 'production':
|
||||
setup_logging(level='INFO', format_type='json')
|
||||
else:
|
||||
setup_logging(level='DEBUG', format_type='human')
|
||||
```
|
||||
|
||||
### Request Correlation
|
||||
```python
|
||||
# Middleware sets request ID
|
||||
from uuid import uuid4
|
||||
from contextvars import copy_context
|
||||
|
||||
def middleware(request):
|
||||
request_id.set(str(uuid4())[:8])
|
||||
# Process request in context
|
||||
return copy_context().run(handler, request)
|
||||
```
|
||||
|
||||
### Migration Strategy
|
||||
1. Phase 1: Add logging module, keep prints
|
||||
2. Phase 2: Convert prints to logger calls
|
||||
3. Phase 3: Remove print statements
|
||||
4. Phase 4: Add structured context
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
1. **Unit Tests**: Mock logger, verify calls
|
||||
2. **Integration Tests**: Verify log output format
|
||||
3. **Performance Tests**: Measure logging overhead
|
||||
4. **Configuration Tests**: Test different levels/formats
|
||||
|
||||
## Configuration
|
||||
|
||||
Environment variables:
|
||||
- `STARPUNK_LOG_LEVEL`: DEBUG|INFO|WARNING|ERROR|CRITICAL
|
||||
- `STARPUNK_LOG_FORMAT`: json|human
|
||||
- `STARPUNK_LOG_FILE`: Path to log file (optional)
|
||||
- `STARPUNK_LOG_ROTATION`: Enable rotation (optional)
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. Never log sensitive data
|
||||
2. Sanitize user input in logs
|
||||
3. Rate limit log output
|
||||
4. Monitor for log injection attacks
|
||||
5. Secure log file permissions

# ADR-055: Error Handling Philosophy
|
||||
|
||||
## Status
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
StarPunk v1.1.1 focuses on production readiness, including graceful error handling. Currently, error handling is inconsistent:
|
||||
- Some errors crash the application
|
||||
- Error messages vary in helpfulness
|
||||
- No distinction between user and system errors
|
||||
- Insufficient context for debugging
|
||||
|
||||
We need a consistent philosophy for handling errors that balances user experience, security, and debuggability.
|
||||
|
||||
## Decision
|
||||
Adopt a layered error handling strategy that provides graceful degradation, helpful user messages, and detailed logging for operators.
|
||||
|
||||
### Error Handling Principles
|
||||
|
||||
1. **Fail Gracefully**: Never crash when recovery is possible
|
||||
2. **Be Helpful**: Provide actionable error messages
|
||||
3. **Log Everything**: Detailed context for debugging
|
||||
4. **Secure by Default**: Don't leak sensitive information
|
||||
5. **User vs System**: Different handling for different audiences
|
||||
|
||||
### Error Categories
|
||||
|
||||
#### 1. User Errors (4xx class)
|
||||
Errors caused by user action or client issues.
|
||||
|
||||
Examples:
|
||||
- Invalid Micropub request
|
||||
- Authentication failure
|
||||
- Missing required fields
|
||||
- Invalid slug format
|
||||
|
||||
Handling:
|
||||
- Return helpful error message
|
||||
- Suggest corrective action
|
||||
- Log at INFO level
|
||||
- Don't expose internals
|
||||
|
||||
#### 2. System Errors (5xx class)
|
||||
Errors in system operation.
|
||||
|
||||
Examples:
|
||||
- Database connection failure
|
||||
- File system errors
|
||||
- Memory exhaustion
|
||||
- Template rendering errors
|
||||
|
||||
Handling:
|
||||
- Generic user message
|
||||
- Detailed logging at ERROR level
|
||||
- Attempt recovery if possible
|
||||
- Alert operators (future)
|
||||
|
||||
#### 3. Configuration Errors
|
||||
Errors due to misconfiguration.
|
||||
|
||||
Examples:
|
||||
- Missing required config
|
||||
- Invalid configuration values
|
||||
- Incompatible settings
|
||||
- Permission issues
|
||||
|
||||
Handling:
|
||||
- Fail fast at startup
|
||||
- Clear error messages
|
||||
- Suggest fixes
|
||||
- Document requirements
|
||||
|
||||
#### 4. Transient Errors
|
||||
Temporary errors that may succeed on retry.
|
||||
|
||||
Examples:
|
||||
- Database lock
|
||||
- Network timeout
|
||||
- Resource temporarily unavailable
|
||||
|
||||
Handling:
|
||||
- Automatic retry with backoff
|
||||
- Log at WARNING level
|
||||
- Fail gracefully after retries
|
||||
- Track frequency
|
||||
|
||||
### Error Response Format
|
||||
|
||||
#### Development Mode
|
||||
```json
|
||||
{
|
||||
"error": {
|
||||
"type": "ValidationError",
|
||||
"message": "Invalid slug format",
|
||||
"details": {
|
||||
"field": "slug",
|
||||
"value": "my/bad/slug",
|
||||
"pattern": "^[a-z0-9-]+$"
|
||||
},
|
||||
"suggestion": "Slugs can only contain lowercase letters, numbers, and hyphens",
|
||||
"documentation": "/docs/api/micropub#slugs",
|
||||
"trace_id": "abc123"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Production Mode
|
||||
```json
|
||||
{
|
||||
"error": {
|
||||
"message": "Invalid request format",
|
||||
"suggestion": "Please check your request and try again",
|
||||
"documentation": "/docs/api/micropub",
|
||||
"trace_id": "abc123"
|
||||
}
|
||||
}
|
||||
```
|
||||
|

### Implementation Pattern
|
||||
|
||||
```python

### Error Handling Middleware
|
||||
|
||||
```python
|
||||
# starpunk/middleware/errors.py
|
||||
def error_handler(func):
|
||||
"""Decorator for consistent error handling"""
|
||||
def wrapper(*args, **kwargs):
|
||||
try:
|
||||
return func(*args, **kwargs)
|
||||
except StarPunkError as e:
|
||||
e.log()
|
||||
return e.to_user_dict(debug=is_debug_mode())
|
||||
except Exception as e:
|
||||
# Unexpected error
|
||||
error = StarPunkError(
|
||||
message="An unexpected error occurred",
|
||||
category=ErrorCategory.SYSTEM,
|
||||
details={'original': str(e)}
|
||||
)
|
||||
error.log()
|
||||
return error.to_user_dict(debug=is_debug_mode())
|
||||
return wrapper
|
||||
```
|
||||
|
||||
### Graceful Degradation Examples
|
||||
|
||||
#### FTS5 Unavailable
|
||||
```python
|
||||
try:
|
||||
# Attempt FTS5 search
|
||||
results = search_with_fts5(query)
|
||||
except FTS5UnavailableError:
|
||||
logger.warning("FTS5 unavailable, falling back to LIKE")
|
||||
results = search_with_like(query)
|
||||
flash("Search is running in compatibility mode")
|
||||
```
|
||||
|
||||
#### Database Lock
|
||||
```python
|
||||
@retry(
|
||||
stop=stop_after_attempt(3),
|
||||
wait=wait_exponential(multiplier=0.5, max=2),
|
||||
retry=retry_if_exception_type(sqlite3.OperationalError)
|
||||
)
|
||||
def execute_query(query):
|
||||
"""Execute with retry for transient errors"""
|
||||
return db.execute(query)
|
||||
```
|
||||
|
||||
#### Missing Optional Feature
|
||||
```python
|
||||
if not config.SEARCH_ENABLED:
|
||||
# Return empty results instead of error
|
||||
return {
|
||||
'results': [],
|
||||
'message': 'Search is disabled on this instance'
|
||||
}
|
||||
```
|
||||
|
||||
## Rationale
|
||||
|
||||
### Why Graceful Degradation?
|
||||
1. **User Experience**: Don't break the whole app
|
||||
2. **Reliability**: Partial functionality better than none
|
||||
3. **Operations**: Easier to diagnose in production
|
||||
4. **Recovery**: System can self-heal from transients
|
||||
|
||||
### Why Different Error Categories?
|
||||
1. **Appropriate Response**: Different errors need different handling
|
||||
2. **Security**: Don't expose internals for system errors
|
||||
3. **Debugging**: Operators need full context
|
||||
4. **User Experience**: Users need actionable messages
|
||||
|
||||
### Why Structured Errors?
|
||||
1. **Consistency**: Predictable error format
|
||||
2. **Parsing**: Tools can process errors
|
||||
3. **Correlation**: Trace IDs link logs to responses
|
||||
4. **Documentation**: Self-documenting error details
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
1. **Better UX**: Helpful error messages
|
||||
2. **Easier Debugging**: Rich context in logs
|
||||
3. **More Reliable**: Graceful degradation
|
||||
4. **Secure**: No information leakage
|
||||
5. **Consistent**: Predictable error handling
|
||||
|
||||
### Negative
|
||||
1. **More Code**: Error handling adds complexity
|
||||
2. **Testing Burden**: Many error paths to test
|
||||
3. **Performance**: Error handling overhead
|
||||
4. **Maintenance**: Error messages need updates
|
||||
|
||||
### Mitigations
|
||||
1. Use error hierarchy to reduce duplication
|
||||
2. Generate tests for error paths
|
||||
3. Cache error messages
|
||||
4. Document error codes clearly
|
||||
|
||||
## Alternatives Considered
|
||||
|
||||
### 1. Let Exceptions Bubble
|
||||
**Pros**: Simple, Python default
|
||||
**Cons**: Poor UX, crashes, no context
|
||||
**Decision**: Not production-ready
|
||||
|
||||
### 2. Generic Error Pages
|
||||
**Pros**: Simple to implement
|
||||
**Cons**: Not helpful, poor API experience
|
||||
**Decision**: Insufficient for Micropub API
|
||||
|
||||
### 3. Error Codes System
|
||||
**Pros**: Precise, machine-readable
|
||||
**Cons**: Complex, needs documentation
|
||||
**Decision**: Over-engineered for our scale
|
||||
|
||||
### 4. Sentry/Error Tracking Service
|
||||
**Pros**: Rich features, alerting
|
||||
**Cons**: External dependency, privacy
|
||||
**Decision**: Conflicts with self-hosted philosophy
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
### Critical Path Protection
|
||||
Always protect critical paths:
|
||||
```python
|
||||
# Never let note creation completely fail
|
||||
try:
|
||||
create_search_index(note)
|
||||
except Exception as e:
|
||||
logger.error("Search indexing failed: %s", e)
|
||||
# Continue without search - note still created
|
||||
```
|
||||
|
||||
### Error Budget
|
||||
Track error rates for SLO monitoring:
|
||||
- User errors: Unlimited (not our fault)
|
||||
- System errors: <0.1% of requests
|
||||
- Configuration errors: 0 after startup
|
||||
- Transient errors: <1% of requests
|
||||
|
||||
### Testing Strategy
|
||||
1. Unit tests for each error class
|
||||
2. Integration tests for error paths
|
||||
3. Chaos testing for transient errors
|
||||
4. User journey tests with errors
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. Never expose stack traces to users
|
||||
2. Sanitize error messages
|
||||
3. Rate limit error endpoints
|
||||
4. Don't leak existence via errors
|
||||
5. Log security errors specially
|
||||
|
||||
## Migration Path
|
||||
|
||||
1. Phase 1: Add error classes
|
||||
2. Phase 2: Wrap existing code
|
||||
3. Phase 3: Add graceful degradation
|
||||
4. Phase 4: Improve error messages
