# Syndication Architecture
|
||||
|
||||
## Overview
|
||||
StarPunk's syndication architecture provides multiple feed formats for content distribution, ensuring broad compatibility with feed readers and IndieWeb tools while maintaining simplicity.
|
||||
|
||||
## Current State (v1.1.0)
|
||||
```
|
||||
┌─────────────┐
|
||||
│ Database │

│ /feed.xml │
|
||||

|

└─────────────┘
|
||||
```
|
||||
|
||||
## Target Architecture (v1.1.2+)
|
||||
```
|
||||
┌─────────────┐
|

|
||||
│ /feed.json │
|
||||
│ (JSON Feed) │
|
||||
└─────────────────────────┘
|
||||
```
|
||||
|
||||
## Design Principles
|
||||
|
||||
### 1. Format Independence
|
||||
Each syndication format operates independently:
|
||||
- No shared state between formats
|
||||
- Failures in one don't affect others
|
||||
- Can be enabled/disabled individually
|
||||
|
||||
### 2. Shared Data Access
|
||||
All formats read from the same data source:
|
||||
- Single query pattern for notes
|
||||
- Consistent ordering (newest first)
|
||||
- Same publication status filtering
|
||||
|
||||
### 3. Library Leverage
|
||||
Maximize use of existing libraries:
|
||||
- `feedgen` for RSS and ATOM
|
||||
- Native Python `json` for JSON Feed
|
||||
- No custom XML generation
|
||||
|
||||
## Component Design
|
||||
|
||||
### Feed Generation Module (`feed.py`)
|
||||
**Current Responsibility**: RSS 2.0 generation
|
||||
**Future Enhancement**: Add ATOM generation function
|
||||
|
||||
```python
|
||||
# Pseudocode structure
|
||||
def generate_rss_feed(notes, config) -> str
|
||||
def generate_atom_feed(notes, config) -> str # New
|
||||
```
|
||||
|
||||
### JSON Feed Module (`json_feed.py`)
|
||||
**New Component**: Dedicated JSON Feed generation
|
||||
|
||||
```python
|
||||
# Pseudocode structure
|
||||
def generate_json_feed(notes, config) -> str
|
||||
def format_json_item(note) -> dict
|
||||
```
|
||||
|
||||
### Route Handlers
|
||||
Simple pass-through to generation functions:
|
||||
```python
|
||||
@app.route('/feed.xml') # Existing
|
||||
@app.route('/feed.atom') # New
|
||||
@app.route('/feed.json') # New
|
||||
```
|
||||
|
||||
## Data Flow
|
||||
|
||||
1. **Request**: Client requests feed at endpoint
|
||||
2. **Query**: Fetch published notes from database
|
||||
3. **Transform**: Convert notes to format-specific structure
|
||||
4. **Serialize**: Generate final output (XML/JSON)
|
||||
5. **Response**: Return with appropriate Content-Type
|
||||
|
||||
## Microformats2 Architecture
|
||||
|
||||
### Template Layer Enhancement
|
||||
Microformats2 operates at the HTML template layer:
|
||||
|
||||
```
|
||||
┌──────────────┐
|
||||
│ Data Model │
|
||||
│ (Notes) │
|
||||
└──────┬───────┘
|
||||
│
|
||||
┌──────▼───────┐
|
||||
│ Templates │
|
||||
│ + mf2 markup│
|
||||
└──────┬───────┘
|
||||
│
|
||||
┌──────▼───────┐
|
||||
│ HTML Output │
|
||||
│ (Semantic) │
|
||||
└──────────────┘
|
||||
```
|
||||
|
||||
### Markup Strategy
|
||||
- **Progressive Enhancement**: Add classes without changing structure
|
||||
- **CSS Independence**: Use mf2-specific classes, not styling classes
|
||||
- **Validation First**: Test with parsers during development
|
||||
|
||||
## Configuration Requirements
|
||||
|
||||
### New Configuration Variables
|
||||
```ini
|
||||
# Author information for h-card
|
||||
AUTHOR_NAME = "Site Author"
|
||||
AUTHOR_URL = "https://example.com"
|
||||
AUTHOR_PHOTO = "/static/avatar.jpg" # Optional
|
||||
|
||||
# Feed settings
|
||||
FEED_LIMIT = 50
|
||||
FEED_FORMATS = "rss,atom,json" # Comma-separated
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Caching Strategy
|
||||
- Feed generation is read-heavy, write-light
|
||||
- Consider caching generated feeds (5-minute TTL)
|
||||
- Invalidate cache on note creation/update
|
||||
|
||||
### Resource Usage
|
||||
- RSS/ATOM: ~O(n) memory for n notes
|
||||
- JSON Feed: Similar memory profile
|
||||
- Microformats2: No additional server resources
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Content Sanitization
|
||||
- HTML in feeds must be properly escaped
|
||||
- CDATA wrapping for RSS/ATOM
|
||||
- JSON string encoding for JSON Feed
|
||||
- No script injection vectors
|
||||
|
||||
### Rate Limiting
|
||||
- Apply same limits as HTML endpoints
|
||||
- Consider aggressive caching for feeds
|
||||
- Monitor for feed polling abuse
|
||||
|
||||
## Testing Architecture
|
||||
|
||||
### Unit Tests
|
||||
```
|
||||
tests/
|
||||
├── test_feed.py # Enhanced for ATOM
|
||||
├── test_json_feed.py # New test module
|
||||
└── test_microformats.py # Template parsing tests
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
- Validate against external validators
|
||||
- Test feed reader compatibility
|
||||
- Verify IndieWeb tool parsing
|
||||
|
||||
## Backwards Compatibility
|
||||
|
||||
### URL Structure
|
||||
- `/feed.xml` remains RSS 2.0 (no breaking change)
|
||||
- New endpoints are additive only
|
||||
- Auto-discovery links updated in templates
|
||||
|
||||
### Database
|
||||
- No schema changes required
|
||||
- All features use existing Note model
|
||||
- No migration needed
|
||||
|
||||
## Future Extensibility
|
||||
|
||||
### Potential Enhancements
|
||||
1. Content negotiation on `/feed`
|
||||
2. WebSub (PubSubHubbub) support
|
||||
3. Custom feed filtering (by tag, date)
|
||||
4. Feed pagination for large sites
|
||||
|
||||
### Format Support Matrix
|
||||
| Format | v1.1.0 | v1.1.2 | v1.2.0 |
|
||||
|--------|--------|--------|--------|
|
||||
| RSS 2.0 | ✅ | ✅ | ✅ |
|
||||
| ATOM | ❌ | ✅ | ✅ |
|
||||
| JSON Feed | ❌ | ✅ | ✅ |
|
||||
| Microformats2 | Partial | Partial | ✅ |
|
||||
|
||||
## Decision Rationale
|
||||
|
||||
### Why Multiple Formats?
|
||||
1. **No Universal Standard**: Different ecosystems prefer different formats
|
||||
2. **Low Maintenance**: Feed formats are stable, rarely change
|
||||
3. **User Choice**: Let users pick their preferred format
|
||||
4. **IndieWeb Philosophy**: Embrace plurality and interoperability
|
||||
|
||||
### Why This Architecture?
|
||||
1. **Simplicity**: Each component has single responsibility
|
||||
2. **Testability**: Isolated components are easier to test
|
||||
3. **Maintainability**: Changes to one format don't affect others
|
||||
4. **Performance**: Can optimize each format independently

## New Components
|
||||
|
||||
### 1. Configuration System
|
||||
|
||||
**Location**: `starpunk/config.py`
|
||||
|
||||
**Responsibilities**:
|
||||
- Load environment variables
|
||||
- Provide type-safe access
|
||||
- Define defaults
|
||||
- Validate configuration
|
||||
|
||||
**Design Pattern**: Singleton with lazy loading
|
||||
|
||||
```python
|
||||
Configuration
|
||||
├── get_bool(key, default)
|
||||
├── get_int(key, default)
|
||||
├── get_float(key, default)
|
||||
└── get_str(key, default)
|
||||
```
|
||||
|
||||
### 2. Performance Monitoring
|
||||
|
||||
**Location**: `starpunk/monitoring/`
|
||||
|
||||
**Components**:
|
||||
- `collector.py`: Metrics collection and storage
|
||||
- `db_monitor.py`: Database performance tracking
|
||||
- `memory.py`: Memory usage monitoring
|
||||
- `http.py`: HTTP request tracking
|
||||
|
||||
**Design Pattern**: Observer with circular buffer
|
||||
|
||||
```python
|
||||
MetricsCollector
|
||||
├── CircularBuffer (1000 metrics)
|
||||
├── SlowQueryLog (100 queries)
|
||||
├── MemoryTracker (background thread)
|
||||
└── Dashboard (read-only view)
|
||||
```
|
||||
|
||||
### 3. Structured Logging
|
||||
|
||||
**Location**: `starpunk/logging.py`
|
||||
|
||||
**Features**:
|
||||
- JSON formatting in production
|
||||
- Human-readable in development
|
||||
- Request correlation IDs
|
||||
- Log levels (DEBUG, INFO, WARNING, ERROR, CRITICAL)
|
||||
|
||||
**Design Pattern**: Decorator with context injection
|
||||
|
||||
### 4. Error Handling
|
||||
|
||||

## Data Flow Improvements
|
||||
|
||||
### Search Data Flow
|
||||
|
||||
```
|
||||
Search Request
|
||||
↓
|
||||
Check Config: SEARCH_ENABLED?
|
||||
├─No→ Return "Search Disabled"
|
||||
└─Yes↓
|
||||
Check FTS5 Available?
|
||||
├─Yes→ FTS5 Search Engine
|
||||
│ ├→ Execute FTS5 Query
|
||||
│ ├→ Calculate Relevance
|
||||
│ └→ Highlight Terms
|
||||
└─No→ Fallback Search Engine
|
||||
├→ Execute LIKE Query
|
||||
├→ No Relevance Score
|
||||
└→ Basic Highlighting
|
||||
```
|
||||
|
||||
### Error Flow
|
||||
|
||||
```
|
||||
Exception Occurs
|
||||
↓
|
||||
Catch in Middleware
|
||||
↓
|
||||
Categorize Error
|
||||
├→ User Error: Log INFO, Return Helpful Message
|
||||
├→ System Error: Log ERROR, Return Generic Message
|
||||
├→ Transient Error: Retry with Backoff
|
||||
└→ Config Error: Fail Fast at Startup
|
||||
```
|
||||
|
||||
## Database Schema Changes
|
||||
|
||||
### Sessions Table Enhancement
|
||||
```sql
|
||||
CREATE TABLE sessions (
|
||||
id TEXT PRIMARY KEY,
|
||||
user_id TEXT NOT NULL,
|
||||
created_at TIMESTAMP NOT NULL,
|
||||
expires_at TIMESTAMP NOT NULL,
|
||||
last_activity TIMESTAMP,
|
||||
remember BOOLEAN DEFAULT FALSE,
|
||||
INDEX idx_sessions_expires (expires_at),
|
||||
INDEX idx_sessions_user (user_id)
|
||||
);
|
||||
```
|
||||
|
||||
