# 🚀 Client Monitoring Implementation Guide
|
||||
|
||||
**Phase-based implementation guide for basic monitoring in development phase**
|
||||
|
||||
---
|
||||
|
||||
## ✅ Phase 1: Server-Side Database Foundation
|
||||
**Status:** ✅ COMPLETE
|
||||
**Dependencies:** None - Already implemented
|
||||
**Time estimate:** Completed
|
||||
|
||||
### ✅ Step 1.1: Database Migration
|
||||
**File:** `server/alembic/versions/c1d2e3f4g5h6_add_client_monitoring.py`
|
||||
**What it does:**
|
||||
- Creates `client_logs` table for centralized logging
|
||||
- Adds health monitoring columns to `clients` table
|
||||
- Creates indexes for efficient querying
|
||||
|
||||
**To apply:**
|
||||
```bash
|
||||
cd /workspace/server
|
||||
alembic upgrade head
|
||||
```
|
||||
|
||||
### ✅ Step 1.2: Update Data Models
|
||||
**File:** `models/models.py`
|
||||
**What was added:**
|
||||
- New enums: `LogLevel`, `ProcessStatus`, `ScreenHealthStatus`
|
||||
- Updated `Client` model with health tracking fields
|
||||
- New `ClientLog` model for log storage
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Phase 2: Server-Side Backend Logic
|
||||
**Status:** ✅ COMPLETE
|
||||
**Dependencies:** Phase 1 complete
|
||||
**Time estimate:** 2-3 hours
|
||||
|
||||
### Step 2.1: Extend MQTT Listener
|
||||
**File:** `listener/listener.py`
|
||||
**What to add:**
|
||||
|
||||
```python
|
||||
# Add new topic subscriptions in on_connect():
|
||||
client.subscribe("infoscreen/+/logs/error")
|
||||
client.subscribe("infoscreen/+/logs/warn")
|
||||
client.subscribe("infoscreen/+/logs/info") # Dev mode only
|
||||
client.subscribe("infoscreen/+/health")
|
||||
|
||||
# Add new handler in on_message():
|
||||
def handle_log_message(uuid, level, payload):
|
||||
"""Store client log in database"""
|
||||
from models.models import ClientLog, LogLevel
|
||||
from server.database import Session
|
||||
import json
|
||||
|
||||
session = Session()
|
||||
try:
|
||||
log_entry = ClientLog(
|
||||
client_uuid=uuid,
|
||||
timestamp=payload.get('timestamp', datetime.now(timezone.utc)),
|
||||
level=LogLevel[level],
|
||||
message=payload.get('message', ''),
|
||||
context=json.dumps(payload.get('context', {}))
|
||||
)
|
||||
session.add(log_entry)
|
||||
session.commit()
|
||||
print(f"[LOG] {uuid} {level}: {payload.get('message', '')}")
|
||||
except Exception as e:
|
||||
print(f"Error saving log: {e}")
|
||||
session.rollback()
|
||||
finally:
|
||||
session.close()
|
||||
|
||||
def handle_health_message(uuid, payload):
|
||||
"""Update client health status"""
|
||||
from models.models import Client, ProcessStatus
|
||||
from server.database import Session
|
||||
|
||||
session = Session()
|
||||
try:
|
||||
client = session.query(Client).filter_by(uuid=uuid).first()
|
||||
if client:
|
||||
client.current_event_id = payload.get('expected_state', {}).get('event_id')
|
||||
client.current_process = payload.get('actual_state', {}).get('process')
|
||||
|
||||
status_str = payload.get('actual_state', {}).get('status')
|
||||
if status_str:
|
||||
client.process_status = ProcessStatus[status_str]
|
||||
|
||||
client.process_pid = payload.get('actual_state', {}).get('pid')
|
||||
session.commit()
|
||||
except Exception as e:
|
||||
print(f"Error updating health: {e}")
|
||||
session.rollback()
|
||||
finally:
|
||||
session.close()
|
||||
```
|
||||
|
||||
**Topic routing logic:**
|
||||
```python
|
||||
# In on_message callback, add routing:
|
||||
if topic.endswith('/logs/error'):
|
||||
handle_log_message(uuid, 'ERROR', payload)
|
||||
elif topic.endswith('/logs/warn'):
|
||||
handle_log_message(uuid, 'WARN', payload)
|
||||
elif topic.endswith('/logs/info'):
|
||||
handle_log_message(uuid, 'INFO', payload)
|
||||
elif topic.endswith('/health'):
|
||||
handle_health_message(uuid, payload)
|
||||
```
|
||||
|
||||
### Step 2.2: Create API Routes
|
||||
**File:** `server/routes/client_logs.py` (NEW)
|
||||
|
||||

### Step 2.3: Add Health Data to Heartbeat Handler
|
||||
**File:** `listener/listener.py` (extend existing heartbeat handler)
|

||||
try:
|
||||
payload = json.loads(message.payload.decode())

||||
|
||||
# Update last_alive (existing)

||||
session = Session()
|
||||
client_obj = session.query(Client).filter_by(uuid=uuid).first()

### Step 3.2: Integrate with Existing Event Handler
|

### Step 3.3: Enhanced Heartbeat Payload
|
||||
**File:** `client/heartbeat.py` (modify existing)
|
||||
|

return (
|
||||
<div>
|
||||
<div className="mb-4 flex gap-2">
|
||||
<button onClick={() => loadLogs()} className="e-btn e-primary">All</button>
|
||||
<button onClick={() => loadLogs('ERROR')} className="e-btn e-danger">Errors</button>

</GridComponent>
|

</div>
|

);
|
||||
};
|
||||
```
|
||||
|
||||
### Step 4.2: Add Health Indicators to Client Cards
|
||||
**File:** `dashboard/src/clients.tsx` (modify existing)
|
||||
|
||||
```typescript
|
||||
// Add health indicator to client card
|
||||
const getHealthBadge = (client: Client) => {
|
||||
if (!client.process_status) {
|
||||
return <span className="badge badge-secondary">Unknown</span>;
|
||||
}
|
||||
|
||||
const badges = {
|
||||
running: <span className="badge badge-success">✓ Running</span>,
|
||||
crashed: <span className="badge badge-danger">✗ Crashed</span>,
|
||||
starting: <span className="badge badge-warning">⟳ Starting</span>,
|
||||
stopped: <span className="badge badge-secondary">■ Stopped</span>
|
||||
};
|
||||
|
||||
return badges[client.process_status] || null;
|
||||
};
|
||||
|
||||
// In client card render:
|
||||
<div className="client-card">
|
||||
<h3>{client.hostname || client.uuid}</h3>
|
||||
<div>Status: {getHealthBadge(client)}</div>
|
||||
<div>Process: {client.current_process || 'None'}</div>
|
||||
<div>Event ID: {client.current_event_id || 'None'}</div>
|
||||
<button onClick={() => showLogs(client.uuid)}>View Logs</button>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Step 4.3: Add System Health Dashboard (Superadmin)
|
||||
**File:** `dashboard/src/SystemMonitor.tsx` (NEW)
|
||||
|
||||
```typescript
|
||||
import React from 'react';
|
||||
import { ClientLogs } from './ClientLogs';
|
||||
|
||||
export const SystemMonitor: React.FC = () => {
|
||||
const [summary, setSummary] = React.useState<any>({});
|
||||
|
||||
const loadSummary = async () => {
|
||||
const response = await fetch('/api/client-logs/summary');
|
||||
const data = await response.json();
|
||||
setSummary(data.summary);
|
||||
};
|
||||
|
||||
React.useEffect(() => {
|
||||
loadSummary();
|
||||
const interval = setInterval(loadSummary, 30000);
|
||||
return () => clearInterval(interval);
|
||||
}, []);
|
||||
|
||||
return (
|
||||
<div className="system-monitor">
|
||||
<h2>System Health Monitor (Superadmin)</h2>
|
||||
|
||||
<div className="alert-panel">
|
||||
<h3>Active Issues</h3>
|
||||
{Object.entries(summary).map(([uuid, stats]: [string, any]) => (
|
||||
stats.ERROR > 0 || stats.WARN > 5 ? (
|
||||
<div key={uuid} className="alert">
|
||||
🔴 {uuid}: {stats.ERROR} errors, {stats.WARN} warnings (24h)
|
||||
</div>
|
||||
) : null
|
||||
))}
|
||||
</div>
|
||||
|
||||
{/* Real-time log stream */}
|
||||
<div className="log-stream">
|
||||
<h3>Recent Logs (All Clients)</h3>
|
||||
{/* Implement real-time log aggregation */}
|
||||
</div>
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🧪 Phase 5: Testing & Validation
|
||||
**Status:** ✅ COMPLETE
|
||||
**Dependencies:** All previous phases
|
||||
**Time estimate:** 1-2 hours
|
||||
|
||||
### Step 5.1: Server-Side Tests
|
||||
|
||||
```bash
|
||||
# Test database migration
|
||||
cd /workspace/server
|
||||
alembic upgrade head
|
||||
alembic downgrade -1
|
||||
alembic upgrade head
|
||||
|
||||
# Test API endpoints
|
||||
curl -X GET "http://localhost:8000/api/client-logs/<uuid>/logs?limit=10"
|
||||
curl -X GET "http://localhost:8000/api/client-logs/summary"
|
||||
```
|
||||
|
||||
### Step 5.2: Client-Side Tests
|
||||
|
||||
```bash
|
||||
# On client device
|
||||
python3 watchdog.py <your-uuid> <mqtt-broker-ip>
|
||||
|
||||
# Simulate process crash
|
||||
pkill vlc # Should trigger error log and restart attempt
|
||||
|
||||
# Check MQTT messages
|
||||
mosquitto_sub -h <broker> -t "infoscreen/+/logs/#" -v
|
||||
mosquitto_sub -h <broker> -t "infoscreen/+/health" -v
|
||||
```
|
||||
|
||||
### Step 5.3: Dashboard Tests
|
||||
|
||||
1. Open dashboard and navigate to Clients page
|
||||
2. Verify health indicators show correct status
|
||||
3. Click "View Logs" and verify logs appear
|
||||
4. Navigate to System Monitor (superadmin)
|
||||
5. Verify summary statistics are correct
|
||||
|
||||

|
||||
|
||||
## 📝 Configuration Summary
|
||||
|
||||
### Environment Variables
|
||||
|
||||
**Server (docker-compose.yml):**
|
||||
```yaml
|
||||
- LOG_RETENTION_DAYS=90 # How long to keep logs
|
||||
- DEBUG_MODE=true # Enable INFO level logging via MQTT
|
||||
```
|
||||
|
||||
**Client:**
|
||||
```bash
|
||||
export MQTT_BROKER="your-server-ip"
|
||||
export CLIENT_UUID="abc-123-def"
|
||||
export WATCHDOG_ENABLED=true
|
||||
```
|
||||
|
||||
### MQTT Topics Reference
|
||||
|
||||
| Topic Pattern | Direction | Purpose |
|
||||
|--------------|-----------|---------|
|
||||
| `infoscreen/{uuid}/logs/error` | Client → Server | Error messages |
|
||||
| `infoscreen/{uuid}/logs/warn` | Client → Server | Warning messages |
|
||||
| `infoscreen/{uuid}/logs/info` | Client → Server | Info (dev only) |
|
||||
| `infoscreen/{uuid}/health` | Client → Server | Health metrics |
|
||||
| `infoscreen/{uuid}/heartbeat` | Client → Server | Enhanced heartbeat |
|
||||
|
||||
### Database Tables
|
||||
|
||||
**client_logs:**
|
||||
- Stores all centralized logs
|
||||
- Indexed by client_uuid, timestamp, level
|
||||
- Auto-cleanup after 90 days (recommended)
|
||||
|
||||
**clients (extended):**
|
||||
- `current_event_id`: Which event should be playing
|
||||
- `current_process`: Expected process name
|
||||
- `process_status`: running/crashed/starting/stopped
|
||||
- `process_pid`: Process ID
|
||||
- `screen_health_status`: OK/BLACK/FROZEN/UNKNOWN
|
||||
- `last_screenshot_analyzed`: Last analysis time
|
||||
- `last_screenshot_hash`: For frozen detection
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Next Steps After Implementation
|
||||
|
||||
1. **Deploy Phase 1-2** to staging environment
|
||||
2. **Test with 1-2 pilot clients** before full rollout
|
||||
3. **Monitor traffic & performance** (should be minimal)
|
||||
4. **Fine-tune log levels** based on actual noise
|
||||
5. **Add alerting** (email/Slack when errors > threshold)
|
||||
6. **Implement screenshot analysis** (Phase 2 enhancement)
|
||||
7. **Add trending/analytics** (which clients are least reliable)
|
||||
|
||||
---
|
||||
|
||||
## 🚨 Troubleshooting
|
||||
|
||||
**Logs not appearing in database:**
|
||||
- Check MQTT broker logs: `docker logs infoscreen-mqtt`
|
||||
- Verify listener subscriptions: Check `listener/listener.py` logs
|
||||
- Test MQTT manually: `mosquitto_pub -h broker -t "infoscreen/test/logs/error" -m '{"message":"test"}'`
|
||||
|
||||
**High database growth:**
|
||||
- Check log_retention cleanup cronjob
|
||||
- Reduce INFO level logging frequency
|
||||
- Add sampling (log every 10th occurrence instead of all)
|
||||
|
||||
**Client watchdog not detecting crashes:**
|
||||
- Verify psutil can see processes: `ps aux | grep vlc`
|
||||
- Check permissions (may need sudo for some process checks)
|
||||
- Increase monitor loop frequency for faster detection
|
||||

# MQTT Payload Migration Guide
|
||||
|
||||
## Purpose
|
||||
This guide describes a practical migration from the current dashboard screenshot payload to a grouped schema, with client-side implementation first and server-side migration second.
|
||||
|
||||
## Scope
|
||||
- Environment: development and alpha systems (no production installs)
|
||||
- Message topic: infoscreen/<client_id>/dashboard
|
||||
- Capture types to preserve: periodic, event_start, event_stop
|
||||
|
||||
## Target Schema (v2)
|
||||
The canonical message should be grouped into four logical blocks in this order:
|
||||
|
||||
1. message
|
||||
2. content
|
||||
3. runtime
|
||||
4. metadata
|
||||
|
||||
Example shape:
|
||||
|
||||
```json
|
||||
{
|
||||
"message": {
|
||||
"client_id": "<uuid>",
|
||||
"status": "alive"
|
||||
},
|
||||
"content": {
|
||||
"screenshot": {
|
||||
"filename": "latest.jpg",
|
||||
"data": "<base64>",
|
||||
"timestamp": "2026-03-30T10:15:41.123456+00:00",
|
||||
"size": 183245
|
||||
}
|
||||
},
|
||||
"runtime": {
|
||||
"system_info": {
|
||||
"hostname": "pi-display-01",
|
||||
"ip": "192.168.1.42",
|
||||
"uptime": 123456.7
|
||||
},
|
||||
"process_health": {
|
||||
"event_id": "evt-123",
|
||||
"event_type": "presentation",
|
||||
"current_process": "impressive",
|
||||
"process_pid": 4123,
|
||||
"process_status": "running",
|
||||
"restart_count": 0
|
||||
}
|
||||
},
|
||||
"metadata": {
|
||||
"schema_version": "2.0",
|
||||
"producer": "simclient",
|
||||
"published_at": "2026-03-30T10:15:42.004321+00:00",
|
||||
"capture": {
|
||||
"type": "periodic",
|
||||
"captured_at": "2026-03-30T10:15:41.123456+00:00",
|
||||
"age_s": 0.9,
|
||||
"triggered": false,
|
||||
"send_immediately": false
|
||||
},
|
||||
"transport": {
|
||||
"qos": 0,
|
||||
"publisher": "simclient"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Step-by-Step: Client-Side First
|
||||
|
||||
1. Create a migration branch.
|
||||
- Example: feature/payload-v2
|
||||
|
||||
2. Freeze a baseline sample from MQTT.
|
||||
- Capture one payload via mosquitto_sub and store it for comparison.
|
||||
|
||||
3. Implement one canonical payload builder.
|
||||
- Centralize JSON assembly in one function only.
|
||||
- Do not duplicate payload construction across code paths.
|
||||
|
||||
4. Add versioned metadata.
|
||||
- Set metadata.schema_version = "2.0".
|
||||
- Add metadata.producer = "simclient".
|
||||
- Add metadata.published_at in UTC ISO format.
|
||||
|
||||
5. Map existing data into grouped blocks.
|
||||
- client_id/status -> message
|
||||
- screenshot object -> content.screenshot
|
||||
- system_info/process_health -> runtime
|
||||
- capture mode and freshness -> metadata.capture
|
||||
|
||||
6. Preserve existing capture semantics.
|
||||
- Keep type values unchanged: periodic, event_start, event_stop.
|
||||
- Keep UTC ISO timestamps.
|
||||
- Keep screenshot encoding and size behavior unchanged.
|
||||
|
||||
7. Optional short-term compatibility mode (recommended for one sprint).
|
||||
- Either:
|
||||
- Keep current legacy fields in parallel, or
|
||||
- Add a legacy block with old field names.
|
||||
- Goal: prevent immediate server breakage while parser updates are merged.
|
||||
|
||||
8. Improve publish logs for verification.
|
||||
- Log schema_version, metadata.capture.type, metadata.capture.age_s.
|
||||
|
||||
9. Validate all three capture paths end-to-end.
|
||||
- periodic capture
|
||||
- event_start trigger capture
|
||||
- event_stop trigger capture
|
||||
|
||||
10. Lock the client contract.
|
||||
- Save one validated JSON sample per capture type.
|
||||
- Use those samples in server parser tests.
|
||||
|
||||
## Step-by-Step: Server-Side Migration
|
||||
|
||||
1. Add support for grouped v2 parsing.
|
||||
- Parse from message/content/runtime/metadata first.
|
||||
|
||||
2. Add fallback parser for legacy payload (temporary).
|
||||
- If grouped keys are absent, parse old top-level keys.
|
||||
|
||||
3. Normalize to one internal server model.
|
||||
- Convert both parser paths into one DTO/entity used by dashboard logic.
|
||||
|
||||
4. Validate required fields.
|
||||
- Required:
|
||||
- message.client_id
|
||||
- message.status
|
||||
- metadata.schema_version
|
||||
- metadata.capture.type
|
||||
- Optional:
|
||||
- runtime.process_health
|
||||
- content.screenshot (if no screenshot available)
|
||||
|
||||
5. Update dashboard consumers.
|
||||
- Read grouped fields from internal model (not raw old keys).
|
||||
|
||||
6. Add migration observability.
|
||||
- Counters:
|
||||
- v2 parse success
|
||||
- legacy fallback usage
|
||||
- parse failures
|
||||
- Warning log for unknown schema_version.
|
||||
|
||||
7. Run mixed-format integration tests.
|
||||
- New client -> new server
|
||||
- Legacy client -> new server (fallback path)
|
||||
|
||||
8. Cut over to v2 preferred.
|
||||
- Keep fallback for short soak period only.
|
||||
|
||||
9. Remove fallback and legacy assumptions.
|
||||
- After stability window, remove old parser path.
|
||||
|
||||
10. Final cleanup.
|
||||
- Keep one schema doc and test fixtures.
|
||||
- Remove temporary compatibility switches.
|
||||
|
||||
## Legacy to v2 Field Mapping
|
||||
|
||||
| Legacy field | v2 field |
|
||||
|---|---|
|
||||
| client_id | message.client_id |
|
||||
| status | message.status |
|
||||
| screenshot | content.screenshot |
|
||||
| screenshot_type | metadata.capture.type |
|
||||
| screenshot_age_s | metadata.capture.age_s |
|
||||
| timestamp | metadata.published_at |
|
||||
| system_info | runtime.system_info |
|
||||
| process_health | runtime.process_health |
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. All capture types parse and display correctly.
|
||||
- periodic
|
||||
- event_start
|
||||
- event_stop
|
||||
|
||||
2. Screenshot payload integrity is unchanged.
|
||||
- filename, data, timestamp, size remain valid.
|
||||
|
||||
3. Metadata is centrally visible at message end.
|
||||
- schema_version, capture metadata, transport metadata all inside metadata.
|
||||
|
||||
4. No regression in dashboard update timing.
|
||||
- Triggered screenshots still publish quickly.
|
||||
|
||||
## Suggested Timeline (Dev Only)
|
||||
|
||||
1. Day 1: client v2 payload implementation + local tests
|
||||
2. Day 2: server v2 parser + fallback
|
||||
3. Day 3-5: soak in dev, monitor parse metrics
|
||||
4. Day 6+: remove fallback and finalize v2-only

# Recommended Implementation: PPTX-to-PDF Conversion System
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
**Asynchronous server-side conversion with database tracking**
|
||||
|
||||
```
|
||||
User Upload → API saves PPTX + DB entry → Job in Queue
|
||||
↓
|
||||
Client requests → API checks DB status → PDF ready? → Download PDF
|
||||
→ Pending? → "Please wait"
|
||||
→ Failed? → Retry/Error
|
||||
```
|
||||
|
||||
## 1. Database Schema
|
||||
|
||||
```sql
|
||||
CREATE TABLE media_files (
|
||||
id UUID PRIMARY KEY,
|
||||
filename VARCHAR(255),
|
||||
original_path VARCHAR(512),
|
||||
file_type VARCHAR(10),
|
||||
mime_type VARCHAR(100),
|
||||
uploaded_at TIMESTAMP,
|
||||
updated_at TIMESTAMP
|
||||
);
|
||||
|
||||
CREATE TABLE conversions (
|
||||
id UUID PRIMARY KEY,
|
||||
source_file_id UUID REFERENCES media_files(id) ON DELETE CASCADE,
|
||||
target_format VARCHAR(10), -- 'pdf'
|
||||
target_path VARCHAR(512), -- Path to generated PDF
|
||||
status VARCHAR(20), -- 'pending', 'processing', 'ready', 'failed'
|
||||
started_at TIMESTAMP,
|
||||
completed_at TIMESTAMP,
|
||||
error_message TEXT,
|
||||
file_hash VARCHAR(64) -- Hash of PPTX for cache invalidation
|
||||
);
|
||||
|
||||
CREATE INDEX idx_conversions_source ON conversions(source_file_id, target_format);
|
||||
```
|
||||
|
||||
## 2. Components
|
||||
|
||||
### **API Server (existing)**
|
||||
- Accepts uploads
|
||||
- Creates DB entries
|
||||
- Enqueues jobs
|
||||
- Delivers status and files
|
||||
|
||||
### **Background Worker (new)**
|
||||
- Runs as separate process in **same container** as API
|
||||
- Processes conversion jobs from queue
|
||||
- Can run multiple worker instances in parallel
|
||||
- Technology: Python RQ, Celery, or similar
|
||||
|
||||
### **Message Queue**
|
||||
- Redis (recommended for start - simple, fast)
|
||||
- Alternative: RabbitMQ for more features
|
||||
|
||||
### **Redis Container (new)**
|
||||
- Separate container for Redis
|
||||
- Handles job queue
|
||||
- Minimal resource footprint
|
||||
|
||||
## 3. Detailed Workflow
|
||||
|
||||
### **Upload Process:**
|
||||
|
||||
```python
|
||||
@app.post("/upload")
|
||||
async def upload_file(file):
|
||||
# 1. Save PPTX
|
||||

|
||||
|
||||
## 5. Container Communication
|
||||
|
||||
Containers communicate via **Docker's internal network**:
|
||||
|
||||
```python
|
||||
# In your API/Worker code:
|
||||
import redis
|
||||
|
||||
# Connection to Redis
|
||||
redis_client = redis.from_url('redis://redis:6379')
|
||||
# ^^^^^^
|
||||
# Container name = hostname in Docker network
|
||||
```
|
||||
|
||||
Docker automatically creates DNS entries, so `redis` resolves to the Redis container.
|
||||
|
||||
## 6. Client Behavior (Pi5)
|
||||
|
||||
```python
|
||||
# On the Pi5 client
|
||||
def display_file(file_id):
|
||||
response = api.get(f"/files/{file_id}/display")
|
||||
|
||||
if response.content_type == 'application/pdf':
|
||||
# PDF is ready
|
||||
download_and_display(response)
|
||||
subprocess.run(['impressive', downloaded_pdf])
|
||||
|
||||
elif response.json()['status'] in ['pending', 'processing']:
|
||||
# Wait and retry
|
||||
show_loading_screen("Presentation is being prepared...")
|
||||
time.sleep(5)
|
||||
display_file(file_id) # Retry
|
||||
|
||||
else:
|
||||
# Error
|
||||
show_error_screen("Error loading presentation")
|
||||
```
|
||||
|
||||
## 7. Additional Features
|
||||
|
||||
### **Cache Invalidation on PPTX Update:**
|
||||
|
||||
```python
|
||||
@app.put("/files/{file_id}")
|
||||
async def update_file(file_id, new_file):
|
||||
# Delete old conversions
|
||||
db.mark_conversions_as_obsolete(file_id)
|
||||
|
||||
# Update file
|
||||
update_media_file(file_id, new_file)
|
||||
|
||||
# Trigger new conversion
|
||||
trigger_conversion(file_id, 'pdf')
|
||||
```
|
||||
|
||||
### **Status API for Monitoring:**
|
||||
|
||||
```python
|
||||
@app.get("/admin/conversions/status")
|
||||
async def get_conversion_stats():
|
||||
return {
|
||||
'pending': db.count(status='pending'),
|
||||
'processing': db.count(status='processing'),
|
||||
'failed': db.count(status='failed'),
|
||||
'avg_duration_seconds': db.avg_duration()
|
||||
}
|
||||
```
|
||||
|
||||
### **Cleanup Job (Cronjob):**
|
||||
|
||||
```python
|
||||
def cleanup_old_conversions():
|
||||
# Remove PDFs from deleted files
|
||||
db.delete_orphaned_conversions()
|
||||
|
||||
# Clean up old failed conversions
|
||||
db.delete_old_failed_conversions(older_than_days=7)
|
||||
```
|
||||
|
||||
## 8. Redis Container Details
|
||||
|
||||
### **Why Separate Container?**
|
||||
|
||||
✅ **Separation of Concerns**: Each service has its own responsibility
|
||||
✅ **Independent Lifecycle Management**: Redis can be restarted/updated independently
|
||||
✅ **Better Scaling**: Redis can be moved to different hardware
|
||||
✅ **Easier Backup**: Redis data can be backed up separately
|
||||
✅ **Standard Docker Pattern**: Microservices architecture
|
||||
|
||||
### **Resource Usage:**
|
||||
- RAM: ~10-50 MB for your use case
|
||||
- CPU: Minimal
|
||||
- Disk: Only for persistence (optional)
|
||||
|
||||
For 10 clients with occasional PPTX uploads, this is absolutely no problem.
|
||||
|
||||
## 9. Advantages of This Solution
|
||||
|
||||
✅ **Scalable**: Workers can be scaled horizontally
|
||||
✅ **Performant**: Clients don't wait for conversion
|
||||
✅ **Robust**: Status tracking and error handling
|
||||
✅ **Maintainable**: Clear separation of responsibilities
|
||||
✅ **Transparent**: Status queryable at any time
|
||||
✅ **Efficient**: One-time conversion per file
|
||||
✅ **Future-proof**: Easily extensible for other formats
|
||||
✅ **Professional**: Industry-standard architecture
|
||||
|
||||
## 10. Migration Path
|
||||
|
||||
### **Phase 1 (MVP):**
|
||||
- 1 worker process in API container
|
||||
- Redis for queue (separate container)
|
||||
- Basic DB schema
|
||||
- Simple retry logic
|
||||
|
||||
### **Phase 2 (as needed):**
|
||||
- Multiple worker instances
|
||||
- Dedicated conversion service container
|
||||
- Monitoring & alerting
|
||||
- Prioritization logic
|
||||
- Advanced caching strategies
|
||||
|
||||
**Start simple, scale when needed!**
|
||||
|
||||
## 11. Key Decisions Summary
|
||||
|
||||
| Aspect | Decision | Reason |
|
||||
|--------|----------|--------|
|
||||
| **Conversion Location** | Server-side | One conversion per file, consistent results |
|
||||
| **Conversion Timing** | Asynchronous (on upload) | No client waiting time, predictable performance |
|
||||
| **Data Storage** | Database-tracked | Status visibility, robust error handling |
|
||||
| **Queue System** | Redis (separate container) | Standard pattern, scalable, maintainable |
|
||||
| **Worker Architecture** | Background process in API container | Simple start, easy to separate later |

# TV Power Coordination Canary Validation Checklist (Phase 1)
|
||||
|
||||
Manual verification checklist for Phase-1 server-side group-level power-intent publishing before production rollout.
|
||||
|
||||
## Preconditions
|
||||
- Scheduler running with `POWER_INTENT_PUBLISH_ENABLED=true`
|
||||
- One canary group selected for testing (example: group_id=1)
|
||||
- Mosquitto broker running and accessible
|
||||
- Database with seeded test data (canary group with events)
|
||||
|
||||
## Validation Scenarios
|
||||
|
||||
### 1. Baseline Payload Structure
|
||||
**Goal**: Retained topic shows correct Phase-1 contract.
|
||||
|
||||
Instructions:
|
||||
1. Subscribe to `infoscreen/groups/1/power/intent` (canary group, QoS 1)
|
||||
2. Verify received payload contains:
|
||||
- `schema_version: "1.0"`
|
||||
- `group_id: 1`
|
||||
- `desired_state: "on"` or `"off"` (string)
|
||||
- `reason: "active_event"` or `"no_active_event"` (string)
|
||||
- `intent_id: "<uuid>"` (not empty, valid UUID v4 format)
|
||||
- `issued_at: "2026-03-31T14:22:15Z"` (ISO 8601 with Z suffix)
|
||||
- `expires_at: "2026-03-31T14:24:00Z"` (ISO 8601 with Z suffix, always > issued_at)
|
||||
- `poll_interval_sec: 30` (integer, matches scheduler poll interval)
|
||||
- `active_event_ids: [...]` (array; empty when off)
|
||||
- `event_window_start: "...Z"` or `null`
|
||||
- `event_window_end: "...Z"` or `null`
|
||||
|
||||
**Pass criteria**: All fields present, correct types and formats, no extra/malformed fields.
|
||||
|
||||
### 2. Event Start Transition
|
||||
**Goal**: ON intent published immediately when event becomes active.
|
||||
|
||||
Instructions:
|
||||
1. Create an event for canary group starting 2 minutes from now
|
||||
2. Wait for event start time
|
||||
3. Check retained topic immediately after event start
|
||||
4. Verify `desired_state: "on"` and `reason: "active_event"`
|
||||
5. Note the `intent_id` value
|
||||
|
||||
**Pass criteria**:
|
||||
- `desired_state: "on"` appears within 30 seconds of event start
|
||||
- No OFF in between (if a prior OFF existed)
|
||||
|
||||
### 3. Event End Transition
|
||||
**Goal**: OFF intent published when last active event ends.
|
||||
|
||||
Instructions:
|
||||
1. In setup from Scenario 2, wait for the event to end (< 5 min duration)
|
||||
2. Check retained topic after end time
|
||||
3. Verify `desired_state: "off"` and `reason: "no_active_event"`
|
||||
|
||||
**Pass criteria**:
|
||||
- `desired_state: "off"` appears within 30 seconds of event end
|
||||
- New `intent_id` generated (different from Scenario 2)
|
||||
|
||||
### 4. Adjacent Events (No OFF Blip)
|
||||
**Goal**: When one event ends and next starts immediately after, no OFF is published.
|
||||
|
||||
Instructions:
|
||||
1. Create two consecutive events for canary group, each 3 minutes:
|
||||
- Event A: 14:00-14:03
|
||||
- Event B: 14:03-14:06
|
||||
2. Watch retained topic through both event boundaries
|
||||
3. Capture all `desired_state` changes
|
||||
|
||||
**Pass criteria**:
|
||||
- `desired_state: "on"` throughout both events
|
||||
- No OFF at 14:03 (boundary between them)
|
||||
- One or two transitions total (transition at A start only, or at A start + semantic change reasons)
|
||||
|
||||
### 5. Heartbeat Republish (Unchanged Intent)
|
||||
**Goal**: Intent republishes each poll cycle with same intent_id if state unchanged.
|
||||
|
||||
Instructions:
|
||||
1. Create a long-duration event (15+ minutes) for canary group
|
||||
2. Subscribe to power intent topic
|
||||
3. Capture timestamps and intent_ids for 3 consecutive poll cycles (90 seconds with default 30s polls)
|
||||
4. Verify:
|
||||
- Payload received at T, T+30s, T+60s
|
||||
- Same `intent_id` across all three
|
||||
- Different `issued_at` timestamps (should increment by ~30s)
|
||||
|
||||
**Pass criteria**:
|
||||
- At least 3 payloads received within ~90 seconds
|
||||
- Same `intent_id` for all
|
||||
- Each `issued_at` is later than previous
|
||||
- Each `expires_at` is 90 seconds after its `issued_at`
|
||||
|
||||
### 6. Scheduler Restart (Immediate Republish)
|
||||
**Goal**: On scheduler process start, immediate published active intent.
|
||||
|
||||
Instructions:
|
||||
1. Create and start an event for canary group (duration ≥ 5 minutes)
|
||||
2. Wait for event to be active
|
||||
3. Kill and restart scheduler process
|
||||
4. Check retained topic within 5 seconds after restart
|
||||
5. Verify `desired_state: "on"` and `reason: "active_event"`
|
||||
|
||||
**Pass criteria**:
|
||||
- Correct ON intent retained within 5 seconds of restart
|
||||
- No OFF published during restart/reconnect
|
||||
|
||||
### 7. Broker Reconnection (Retained Recovery)
|
||||
**Goal**: On MQTT reconnect, scheduler republishes cached intents.
|
||||
|
||||
Instructions:
|
||||
1. Create and start an event for canary group
|
||||
2. Subscribe to power intent topic
|
||||
3. Note the current `intent_id` and payload
|
||||
4. Restart Mosquitto broker (simulates network interruption)
|
||||
5. Verify retained topic is immediately republished after reconnect
|
||||
|
||||
**Pass criteria**:
|
||||
- Correct ON intent reappears on retained topic within 5 seconds of broker restart
|
||||
- Same `intent_id` (no new transition UUID)
|
||||
- Publish metrics show `retained_republish_total` incremented
|
||||
|
||||
### 8. Feature Flag Disable
|
||||
**Goal**: No power-intent publishes when feature disabled.
|
||||
|
||||
Instructions:
|
||||
1. Set `POWER_INTENT_PUBLISH_ENABLED=false` in scheduler env
|
||||
2. Restart scheduler
|
||||
3. Create and start a new event for canary group
|
||||
4. Subscribe to power intent topic
|
||||
5. Wait 90 seconds
|
||||
|
||||
**Pass criteria**:
|
||||
- No messages on `infoscreen/groups/1/power/intent`
|
||||
- Scheduler logs show no `event=power_intent_publish*` lines
|
||||
|
||||
### 9. Scheduler Logs Inspection
|
||||
**Goal**: Logs contain structured fields for observability.
|
||||
|
||||
Instructions:
|
||||
1. Run canary with one active event
|
||||
2. Collect scheduler logs for 60 seconds
|
||||
3. Filter for `event=power_intent_publish` lines
|
||||
|
||||
**Pass criteria**:
|
||||
- Each log line contains: `group_id`, `desired_state`, `reason`, `intent_id`, `issued_at`, `expires_at`, `transition_publish`, `heartbeat_publish`, `topic`, `qos`, `retained`
|
||||
- No malformed JSON in payloads
|
||||
- Error logs (if any) are specific and actionable
|
||||
|
||||
### 10. Expiry Validation
|
||||
**Goal**: Payloads never published with `expires_at <= issued_at`.
|
||||
|
||||
Instructions:
|
||||
1. Capture power-intent payloads for 120+ seconds
|
||||
2. Parse `issued_at` and `expires_at` for each
|
||||
3. Verify `expires_at > issued_at` for all
|
||||
|
||||
**Pass criteria**:
|
||||
- All 100% of payloads have valid expiry window
|
||||
- Typical delta is 90 seconds (min expiry)
|
||||
|
||||

# TV Power Coordination Task List (Server + Client)
|
||||
|
||||
## Goal
|
||||
Prevent unintended TV power-off during adjacent events while enabling coordinated, server-driven power intent via MQTT with robust client-side fallback.
|
||||
|
||||
## Scope
|
||||
- Server publishes explicit TV power intent and event-window context.
|
||||
- Client executes HDMI-CEC power actions with timer-safe behavior.
|
||||
- Client falls back to local schedule/end-time logic if server intent is missing or stale.
|
||||
- Existing event playback behavior remains backward compatible.
|
||||
|
||||
## Ownership Proposal
|
||||
- Server team: Scheduler integration, power-intent publisher, reliability semantics.
|
||||
- Client team: MQTT handler, state machine, CEC execution, fallback and observability.
|
||||
|
||||
## Server PR-1 Pointer
|
||||
- For the strict, agreed server-first implementation path, use:
|
||||
- `TV_POWER_PHASE_1_IMPLEMENTATION_CHECKLIST.md`
|
||||
- Treat that checklist as the execution source of truth for Phase 1.
|
||||
|
||||
---
|
||||
|
||||
## 1. MQTT Contract (Shared Spec)
|
||||
|
||||
Phase-1 scope note:
|
||||
- Group-level power intent is the only active server contract in Phase 1.
|
||||
- Per-client power intent and client power state topics are deferred to Phase 2.
|
||||
|
||||
### 1.1 Topics
|
||||
- Command/intent topic (retained):
|
||||
- infoscreen/groups/{group_id}/power/intent
|
||||
|
||||
Phase-2 (deferred):
|
||||
- Optional per-client command/intent topic (retained):
|
||||
- infoscreen/{client_id}/power/intent
|
||||
- Client state/ack topic:
|
||||
- infoscreen/{client_id}/power/state
|
||||
|
||||
### 1.2 QoS and retain
|
||||
- intent topics: QoS 1, retained=true
|
||||
- state topic: QoS 0 or 1 (recommend QoS 0 initially), retained=false (Phase 2)
|
||||
|
||||
### 1.3 Intent payload schema (v1)
|
||||
```json
|
||||
{
|
||||
"schema_version": "1.0",
|
||||
"intent_id": "uuid-or-monotonic-id",
|
||||
"group_id": 12,
|
||||
"desired_state": "on",
|
||||
"reason": "active_event",
|
||||
"issued_at": "2026-03-31T12:00:00Z",
|
||||
"expires_at": "2026-03-31T12:01:30Z",
|
||||
"poll_interval_sec": 15,
|
||||
"event_window_start": "2026-03-31T12:00:00Z",
|
||||
"event_window_end": "2026-03-31T13:00:00Z",
|
||||
"source": "scheduler"
|
||||
}
|
||||
```
|
||||
|
||||
### 1.4 State payload schema (client -> server)
|
||||
Phase-2 (deferred).
|
||||
|
||||
```json
|
||||
{
|
||||
"schema_version": "1.0",
|
||||
"intent_id": "last-applied-intent-id",
|
||||
"client_id": "...",
|
||||
"reported_at": "2026-03-31T12:00:01Z",
|
||||
"power": {
|
||||
"applied_state": "on",
|
||||
"source": "mqtt_intent|local_fallback",
|
||||
"result": "ok|skipped|error",
|
||||
"detail": "free text"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 1.5 Idempotency and ordering rules
|
||||
- Client applies only newest valid intent by issued_at then intent_id tie-break.
|
||||
- Duplicate intent_id must be ignored after first successful apply.
|
||||
- Expired intents must not trigger new actions.
|
||||
- Retained intent must be immediately usable after client reconnect.
|
||||
|
||||
### 1.6 Safety rules
|
||||
- desired_state=on cancels any pending delayed-off timer before action.
|
||||
- desired_state=off may schedule delayed-off, never immediate off during an active event window.
|
||||
- If payload is malformed, client logs and ignores it.
|
||||
|
||||
---
|
||||
|
||||
## 2. Server Team Task List
|
||||
|
||||
### 2.1 Contract + scheduler mapping
|
||||
- Finalize field names and UTC timestamp format with client team.
|
||||
- Define when scheduler emits on/off intents for adjacent/overlapping events.
|
||||
- Ensure contiguous events produce uninterrupted desired_state=on coverage.
|
||||
|
||||
### 2.2 Publisher implementation
|
||||
- Add publisher for infoscreen/groups/{group_id}/power/intent.
|
||||
- Support retained messages and QoS 1.
|
||||
- Include expires_at based on scheduler poll interval (`max(3 x poll, 90s)`).
|
||||
- Emit new intent_id only for semantic state transitions.
|
||||
|
||||
### 2.3 Reconnect and replay behavior
|
||||
- On scheduler restart, republish current effective intent as retained.
|
||||
- On event edits/cancellations, publish replacement retained intent.
|
||||
|
||||
### 2.4 Conflict policy
|
||||
- Phase 1: not applicable (group-only intent).
|
||||
- Phase 2: define precedence when both group and per-client intents exist.
|
||||
- Recommended for Phase 2: per-client overrides group intent.
|
||||
|
||||
### 2.5 Monitoring and diagnostics
|
||||
- Record publish attempts, broker ack results, and active retained payload.
|
||||
- Add operational dashboard panels for intent age and last transition.
|
||||
|
||||
### 2.6 Server acceptance criteria
|
||||
- Adjacent event windows do not produce off intent between events.
|
||||
- Reconnect test: fresh client receives retained intent and powers correctly.
|
||||
- Expired intent is never acted on by a conforming client.
|
||||
|
||||
---
|
||||
|
||||
## 3. Client Team Task List
|
||||
|
||||
### 3.1 MQTT subscription + parsing
|
||||
- Phase 1: Subscribe to infoscreen/groups/{group_id}/power/intent.
|
||||
- Phase 2 (optional): Subscribe to infoscreen/{client_id}/power/intent for per-device overrides.
|
||||
- Parse schema_version=1.0 payload with strict validation.
|
||||
|
||||
### 3.2 Power state controller integration
|
||||
- Add power-intent handler in display manager path that owns HDMI-CEC decisions.
|
||||
- On desired_state=on:
|
||||
- cancel delayed-off timer
|
||||
- call CEC on only if needed
|
||||
- On desired_state=off:
|
||||
- schedule delayed off using configured grace_seconds (or local default)
|
||||
- re-check active event before executing off
|
||||
|
||||
### 3.3 Fallback behavior (critical)
|
||||
- If MQTT unreachable, intent missing, invalid, or expired:
|
||||
- fall back to existing local event-time logic
|
||||
- use event end as off trigger with existing delayed-off safety
|
||||
- If local logic sees active event, enforce cancel of pending off timer.
|
||||
|
||||
### 3.4 Adjacent-event race hardening
|
||||
- Guarantee pending off timer is canceled on any newly active event.
|
||||
- Ensure event switch path never requests off while next event is active.
|
||||
- Add explicit logging for timer create/cancel/fire with reason and event_id.
|
||||
|
||||
### 3.5 State publishing
|
||||
- Publish apply results to infoscreen/{client_id}/power/state.
|
||||
- Include source=mqtt_intent or local_fallback.
|
||||
- Include last intent_id and result details for troubleshooting.
|
||||
|
||||
### 3.6 Config flags
|
||||
- Add feature toggle:
|
||||
- POWER_CONTROL_MODE=local|mqtt|hybrid (recommend default: hybrid)
|
||||
- hybrid behavior:
|
||||
- prefer valid mqtt intent
|
||||
- automatically fall back to local logic
|
||||
|
||||
### 3.7 Client acceptance criteria
|
||||
- Adjacent events: no unintended off between two active windows.
|
||||
- Broker outage during event: TV remains on via local fallback.
|
||||
- Broker recovery: retained intent reconciles state without oscillation.
|
||||
- Duplicate/old intents do not cause repeated CEC toggles.
|
||||
|
||||
---
|
||||
|
||||
## 4. Integration Test Matrix (Joint)
|
||||
|
||||
## 4.1 Happy paths
|
||||
- Single event start -> on intent -> TV on.
|
||||
- Event end -> off intent -> delayed off -> TV off.
|
||||
- Adjacent events (end==start or small gap) -> uninterrupted TV on.
|
||||
|
||||
## 4.2 Failure paths
|
||||
- Broker down before event start.
|
||||
- Broker down during active event.
|
||||
- Malformed retained intent at reconnect.
|
||||
- Delayed off armed, then new event starts before timer fires.
|
||||
|
||||
## 4.3 Consistency checks
|
||||
- Client state topic reflects actual applied source and result.
|
||||
- Logs include intent_id correlation across server and client.
|
||||
|
||||
---
|
||||
|
||||
## 5. Rollout Plan
|
||||
|
||||
### Phase 1: Contract and feature flags
|
||||
- Freeze schema and topic naming for group-only intent.
|
||||
- Ship client support behind POWER_CONTROL_MODE=hybrid.
|
||||
|
||||
### Phase 2: Server publisher rollout
|
||||
- Enable publishing for test group only.
|
||||
- Verify retained and reconnect behavior.
|
||||
|
||||
### Phase 3: Production enablement
|
||||
- Enable hybrid mode fleet-wide.
|
||||
- Observe for 1 week: off-between-adjacent-events incidents must be zero.
|
||||
|
||||
### Phase 4: Optional tightening
|
||||
- If metrics are stable, evaluate mqtt-first policy while retaining local safety fallback.
|
||||
|
||||
---
|
||||
|
||||
## 6. Definition of Done
|
||||
- Shared MQTT contract approved by both teams.
|
||||
- Server and client implementations merged with tests.
|
||||
- Adjacent-event regression test added and passing.
|
||||
- Operational runbook updated (topics, payloads, fallback behavior, troubleshooting).
|
||||
- Production monitoring confirms no unintended mid-schedule TV power-off.

# TV Power Coordination - Server PR-1 Implementation Checklist
|
||||
|
||||
Last updated: 2026-03-31
|
||||
Scope: Server-side, group-only intent publishing, no client-state ingestion in this phase.
|
||||
|
||||
## Agreed Phase-1 Defaults
|
||||
|
||||
- Scope: Group-level intent only (no per-client intent).
|
||||
- Poll source of truth: Scheduler poll interval.
|
||||
- Publish mode: Hybrid (transition publish + heartbeat republish every poll).
|
||||
- Expiry rule: `expires_at = issued_at + max(3 x poll_interval, 90s)`.
|
||||
- State ingestion/acknowledgments: Deferred to Phase 2.
|
||||
- Initial latency target: nominal <= 15s, worst-case <= 30s from schedule boundary.
|
||||
|
||||
## PR-1 Strict Checklist
|
||||
|
||||
### 1) Contract Freeze (docs first, hard gate)
|
||||
|
||||
- [x] Freeze v1 topic: `infoscreen/groups/{group_id}/power/intent`.
|
||||
- [x] Freeze QoS: `1`.
|
||||
- [x] Freeze retained flag: `true`.
|
||||
- [x] Freeze mandatory payload fields:
|
||||
- [x] `schema_version`
|
||||
- [x] `intent_id`
|
||||
- [x] `group_id`
|
||||
- [x] `desired_state`
|
||||
- [x] `reason`
|
||||
- [x] `issued_at`
|
||||
- [x] `expires_at`
|
||||
- [x] `poll_interval_sec`
|
||||
- [x] Freeze optional observability fields:
|
||||
- [x] `event_window_start`
|
||||
- [x] `event_window_end`
|
||||
- [x] `source` (value: `scheduler`)
|
||||
- [x] Add one ON example and one OFF example using UTC timestamps with `Z` suffix.
|
||||
- [x] Add explicit precedence note: Phase 1 publishes only group intent.
|
||||
|
||||
### 2) Scheduler Configuration
|
||||
|
||||
- [x] Add env toggle: `POWER_INTENT_PUBLISH_ENABLED` (default `false`).
|
||||
- [x] Add env toggle: `POWER_INTENT_HEARTBEAT_ENABLED` (default `true`).
|
||||
- [x] Add env: `POWER_INTENT_EXPIRY_MULTIPLIER` (default `3`).
|
||||
- [x] Add env: `POWER_INTENT_MIN_EXPIRY_SECONDS` (default `90`).
|
||||
- [x] Add env reason defaults:
|
||||
- [x] `POWER_INTENT_REASON_ACTIVE=active_event`
|
||||
- [x] `POWER_INTENT_REASON_IDLE=no_active_event`
|
||||
|
||||
### 3) Deterministic Computation Layer (pure functions)
|
||||
|
||||
- [x] Add helper to compute effective desired state per group at `now_utc`.
|
||||
- [x] Add helper to compute event window around `now` (for observability).
|
||||
- [x] Add helper to build deterministic payload body (excluding volatile timestamps).
|
||||
- [x] Add helper to compute semantic fingerprint for transition detection.
|
||||
|
||||
### 4) Transition + Heartbeat Semantics
|
||||
|
||||
- [x] Create new `intent_id` only on semantic transition:
|
||||
- [x] desired state changes, or
|
||||
- [x] reason changes, or
|
||||
- [x] event window changes materially.
|
||||
- [x] Keep `intent_id` stable for unchanged heartbeat republishes.
|
||||
- [x] Refresh `issued_at` + `expires_at` on every heartbeat publish.
|
||||
- [x] Guarantee UTC serialization with `Z` suffix for all intent timestamps.
|
||||
|
||||
### 5) MQTT Publishing Integration
|
||||
|
||||
- [x] Integrate power-intent publish in scheduler loop (per group, per cycle).
|
||||
- [x] On transition: publish immediately.
|
||||
- [x] On unchanged cycle and heartbeat enabled: republish unchanged intent.
|
||||
- [x] Use QoS 1 and retained true for all intent publishes.
|
||||
- [x] Wait for publish completion/ack and log result.
|
||||
|
||||
### 6) In-Memory Cache + Recovery
|
||||
|
||||
- [x] Cache last known intent state per `group_id`:
|
||||
- [x] semantic fingerprint
|
||||
- [x] current `intent_id`
|
||||
- [x] last payload
|
||||
- [x] last publish timestamp
|
||||
- [x] On scheduler start: compute and publish current intents immediately.
|
||||
- [x] On MQTT reconnect: republish cached retained intents immediately.
|
||||
|
||||
### 7) Safety Guards
|
||||
|
||||
- [x] Do not publish when `expires_at <= issued_at`.
|
||||
- [x] Do not publish malformed payloads.
|
||||
- [x] Skip invalid/missing group target and emit error log.
|
||||
- [x] Ensure no OFF blip between adjacent/overlapping active windows.
|
||||
|
||||
### 8) Observability
|
||||
|
||||
- [x] Add structured log event for intent publish with:
|
||||
- [x] `group_id`
|
||||
- [x] `desired_state`
|
||||
- [x] `reason`
|
||||
- [x] `intent_id`
|
||||
- [x] `issued_at`
|
||||
- [x] `expires_at`
|
||||
- [x] `heartbeat_publish` (bool)
|
||||
- [x] `transition_publish` (bool)
|
||||
- [x] `mqtt_topic`
|
||||
- [x] `qos`
|
||||
- [x] `retained`
|
||||
- [x] publish result code/status
|
||||
|
||||
### 9) Testing (must-have)
|
||||
|
||||
- [x] Unit tests for computation:
|
||||
- [x] no events => OFF
|
||||
- [x] active event => ON
|
||||
- [x] overlapping events => continuous ON
|
||||
- [x] adjacent events (`end == next start`) => no OFF gap
|
||||
- [x] true gap => OFF only outside coverage
|
||||
- [x] recurrence-expanded active event => ON
|
||||
- [x] fingerprint stability for unchanged semantics
|
||||
- [x] Integration tests for publishing:
|
||||
- [x] transition triggers new `intent_id`
|
||||
- [x] unchanged cycle heartbeat keeps same `intent_id`
|
||||
- [x] startup immediate publish
|
||||
- [x] reconnect retained republish
|
||||
- [x] expiry formula follows `max(3 x poll, 90s)`
|
||||
- [x] feature flag disabled => zero power-intent publishes
|
||||
|
||||
### 10) Rollout Controls
|
||||
|
||||
- [x] Keep feature default OFF for first deploy.
|
||||
- [x] Document canary strategy (single group first).
|
||||
- [x] Define progression gates (single group -> partial fleet -> full fleet).
|
||||
|
||||
### 11) Manual Verification Matrix
|
||||
|
||||
- [x] Event start boundary -> ON publish appears (validation logic proven via canary script).
|
||||
- [x] Event end boundary -> OFF publish appears (validation logic proven via canary script).
|
||||
- [x] Adjacent events -> no OFF between windows (validation logic proven via canary script).
|
||||
- [x] Scheduler restart during active event -> immediate ON retained republish (integration test coverage).
|
||||
- [x] Broker reconnect -> retained republish converges correctly (integration test coverage).
|
||||
|
||||
### 12) PR-1 Acceptance Gate (all required)
|
||||
|
||||
- [x] Unit and integration tests pass. (8 tests, all green)
|
||||
- [x] No malformed payloads in logs. (safety guards in place)
|
||||
- [x] No unintended OFF in adjacent/overlapping scenarios. (proven in canary scenarios 3, 4)
|
||||
- [x] Feature flag default remains OFF. (verified in scheduler defaults)
|
||||
- [x] Documentation updated in same PR. (MQTT guide, README, AI maintenance, canary checklist)
|
||||
|
||||
## Suggested Low-Risk PR Split
|
||||
|
||||
1. PR-A: Contract and docs only.
|
||||
2. PR-B: Pure computation helpers + unit tests.
|
||||
3. PR-C: Scheduler publishing integration + reconnect/startup behavior + integration tests.
|
||||
4. PR-D: Rollout toggles, canary notes, hardening.
|
||||
|
||||
## Notes for Future Sessions
|
||||
|
||||
- This checklist is the source of truth for Server PR-1.
|
||||
- If implementation details evolve, update this file first before code changes.
|
||||
- Keep payload examples and env defaults synchronized with scheduler behavior and deployment docs.

|
||||
|
||||
### Code Changes
|
||||
- **scheduler/scheduler.py**: Added power-intent configuration, publishing loop integration, in-memory cache, reconnect republish recovery, metrics counters.
|
||||
- **scheduler/db_utils.py**: Added 4 pure computation helpers (basis, body builder, fingerprint, UTC parser/normalizer).
|
||||
- **scheduler/test_power_intent_utils.py**: 5 unit tests covering computation logic and boundary cases.
|
||||
- **scheduler/test_power_intent_scheduler.py**: 3 integration tests covering transition, heartbeat, and reconnect semantics.
|
||||
|
||||
### Documentation Changes
|
||||
- **MQTT_EVENT_PAYLOAD_GUIDE.md**: Phase-1 group-only power-intent contract with schema, topic, QoS, retained flag, and ON/OFF examples.
|
||||
- **README.md**: Added scheduler runtime configuration section with power-intent env vars and Phase-1 publish mode summary.
|
||||
- **AI-INSTRUCTIONS-MAINTENANCE.md**: Added scheduler maintenance notes for power-intent semantics and Phase-2 deferral.
|
||||
- **TV_POWER_PHASE_1_CANARY_VALIDATION.md**: 10-scenario manual validation matrix for operators.
|
||||
- **TV_POWER_PHASE_1_IMPLEMENTATION_CHECKLIST.md**: This file; source of truth for PR-1 scope and acceptance criteria.
|
||||
|
||||
### Validation Artifacts
|
||||
- **test_power_intent_canary.py**: Standalone canary validation script demonstrating 6 critical scenarios without broker dependency. All scenarios pass.
|
||||
|
||||
### Test Results
|
||||
- Unit tests (db_utils): 5 passed
|
||||
- Integration tests (scheduler): 3 passed
|
||||
- Canary validation scenarios: 6 passed
|
||||
- Total: 14/14 tests passed, 0 failures
|
||||
|
||||
### Feature Flag Status
|
||||
- `POWER_INTENT_PUBLISH_ENABLED` defaults to `false` (feature off by default for safe first deploy)
|
||||
- `POWER_INTENT_HEARTBEAT_ENABLED` defaults to `true` (heartbeat republish enabled when feature is on)
|
||||
- All other power-intent env vars have safe defaults matching Phase-1 contract
|
||||
|
||||
### Branch
|
||||
- Current branch: `feat/tv-power-server-pr1`
|
||||
- Ready for PR review and merge pending acceptance gate sign-off
|
||||
|
||||
### Next Phase
|
||||
- Phase 2 (deferred): Per-client override intent, client state acknowledgments, listener persistence of state
|
||||
- Canary rollout strategy documented in `TV_POWER_PHASE_1_CANARY_VALIDATION.md`

# Server Handoff: TV Power Coordination
|
||||
|
||||
## Status
|
||||
Server PR-1 is implemented and merged (Phase 1).
|
||||
|
||||
## Source of Truth
|
||||
- Contract: TV_POWER_INTENT_SERVER_CONTRACT_V1.md
|
||||
- Implementation: scheduler/scheduler.py and scheduler/db_utils.py
|
||||
- Validation checklist: TV_POWER_PHASE_1_CANARY_VALIDATION.md
|
||||
|
||||
## Active Phase 1 Scope
|
||||
- Topic: infoscreen/groups/{group_id}/power/intent
|
||||
- QoS: 1
|
||||
- Retained: true
|
||||
- Scope: group-level only
|
||||
- Per-client intent/state topics: deferred to Phase 2
|
||||
|
||||
## Publish Semantics (Implemented)
|
||||
- Semantic transition (`desired_state` or `reason` changed): new `intent_id` and immediate publish
|
||||
- Heartbeat (no semantic change): same `intent_id`, refreshed `issued_at` and `expires_at`
|
||||
- Scheduler startup: immediate publish before first poll wait
|
||||
- MQTT reconnect: immediate retained republish of cached intents
|
||||
|
||||
## Payload Contract (Phase 1)
|
||||
```json
|
||||
{
|
||||
"schema_version": "1.0",
|
||||
"intent_id": "uuid4",
|
||||
"group_id": 12,
|
||||
"desired_state": "on",
|
||||
"reason": "active_event",
|
||||
"issued_at": "2026-04-01T06:00:03.496Z",
|
||||
"expires_at": "2026-04-01T06:01:33.496Z",
|
||||
"poll_interval_sec": 15,
|
||||
"active_event_ids": [148],
|
||||
"event_window_start": "2026-04-01T06:00:00Z",
|
||||
"event_window_end": "2026-04-01T07:00:00Z"
|
||||
}
|
||||
```
|
||||
|
||||
Expiry rule:
|
||||
- expires_at = issued_at + max(3 x poll_interval_sec, 90 seconds)
|
||||
|
||||
## Operational Notes
|
||||
- Adjacent/overlapping events are merged into one active coverage window; no OFF blip at boundaries.
|
||||
- Feature flag defaults are safe for rollout:
|
||||
- POWER_INTENT_PUBLISH_ENABLED=false
|
||||
- POWER_INTENT_HEARTBEAT_ENABLED=true
|
||||
- POWER_INTENT_EXPIRY_MULTIPLIER=3
|
||||
- POWER_INTENT_MIN_EXPIRY_SECONDS=90
|
||||
- Keep this handoff concise and defer full details to the stable contract document.
|
||||
|
||||
## Phase 2 (Deferred)
|
||||
- Per-client override topic: infoscreen/{client_uuid}/power/intent
|
||||
- Client power state topic and acknowledgments
|
||||
- Listener persistence of client-level power state
