# A1→A2 Empty Folder Retry Logic
## Preventing Infinite Error Emails for Empty Campaigns

**Purpose:** Avoid sending "no assets found" error emails every 3 minutes indefinitely when a campaign is set to A1 but has no master assets.

**Author:** Claude Code
**Date:** January 31, 2026
**Related Files:**
- `scripts/a1_to_a2_box_uploader.py` (main script)
- `scripts/shared/database.py` (retry tracking methods)
- `database/migrations/003_add_a1_retry_tracking.sql` (schema)

---

## How It Works

### The Problem
Previously, when a campaign had status A1 but the Master Assets folder was empty:
- System sent error email every 3 minutes
- Campaign remained in A1 status forever
- No distinction between temporary and permanent failures
- Notification fatigue for support team

### The Solution
Three-attempt retry mechanism with permanent failure tracking:

**Flow:**
1. Campaign in A1 status with no assets → Attempt 1 (email sent, retry_count=1)
2. Still no assets after 3 minutes → Attempt 2 (email sent, retry_count=2)
3. Still no assets after 6 minutes → Attempt 3 (email sent, retry_count=3, permanently_failed=TRUE)
4. Campaign now skipped on all future runs → Manual reset required

### Database Tracking

Four new fields in `campaign_status` table:
- `a1_retry_count` (INTEGER): Number of failed attempts (0-3)
- `a1_last_retry_at` (TIMESTAMP): When last attempt occurred
- `a1_permanently_failed` (BOOLEAN): TRUE after 3 failures
- `a1_failure_reason` (TEXT): Why it failed (e.g., "No master assets found")

## Configuration

### Maximum Retry Attempts

**Current Setting:** 3 attempts

**To Change:** Edit `/Users/nickviljoen/Desktop/Ferrero/ferrero-opentext/Python-Version/scripts/shared/database.py`

```python
def increment_a1_retry(self, campaign_id, campaign_number, campaign_name, reason):
    """..."""
    # Maximum retry attempts before marking as permanently failed
    MAX_RETRIES = 3  # CHANGE THIS NUMBER
```

**Recommendation:** Keep at 3. This allows:
- Immediate notification (attempt 1)
- Short-term retry (attempt 2 after 3 min)
- Medium-term retry (attempt 3 after 6 min)
- Permanent failure (after 9 minutes total)

---

## Email Notifications

### Retry Email (Attempts 1-2)
**Subject:** ⚠️ No Assets Found (Attempt X/3) - Campaign {name}
**Recipients:** Error notification list
**Content:**
- Current retry count
- Remaining attempts
- What happens next

### Final Failure Email (Attempt 3)
**Subject:** ❌ PERMANENTLY FAILED - Campaign {name} (No Assets After 3 Attempts)
**Recipients:** Error notification list
**Content:**
- Campaign marked as permanently failed
- Required actions to fix
- SQL command to manually reset

---

## Manual Operations

### Check Campaign Retry Status

```sql
SELECT campaign_number, campaign_name, status,
       a1_retry_count, a1_last_retry_at,
       a1_permanently_failed, a1_failure_reason
FROM campaign_status
WHERE campaign_id = 'YOUR_CAMPAIGN_ID';
```

### Reset Single Campaign

```sql
UPDATE campaign_status
SET a1_retry_count = 0,
    a1_last_retry_at = NULL,
    a1_permanently_failed = FALSE,
    a1_failure_reason = NULL
WHERE campaign_id = 'YOUR_CAMPAIGN_ID';
```

**Or using psql command:**
```bash
PGPASSWORD=ferrero_pass_2025 psql -h localhost -p 5437 -U ferrero_user -d ferrero_tracking <<EOF
UPDATE campaign_status
SET a1_retry_count = 0,
    a1_last_retry_at = NULL,
    a1_permanently_failed = FALSE,
    a1_failure_reason = NULL
WHERE campaign_id = 'YOUR_CAMPAIGN_ID';
EOF
```

### Reset All Failed Campaigns

```sql
UPDATE campaign_status
SET a1_retry_count = 0,
    a1_last_retry_at = NULL,
    a1_permanently_failed = FALSE,
    a1_failure_reason = NULL
WHERE a1_permanently_failed = TRUE;
```

### View All Failed Campaigns

```sql
SELECT campaign_number, campaign_name,
       a1_retry_count, a1_last_retry_at, a1_failure_reason
FROM campaign_status
WHERE a1_permanently_failed = TRUE
ORDER BY a1_last_retry_at DESC;
```

## Failure Scenarios

### Scenario 1: Temporary Empty Folder
**What Happens:**
- Attempt 1: Email sent, retry counter = 1
- Assets added to folder before attempt 2
- Next run finds assets, processes successfully
- Retry counter automatically reset to 0

**Result:** Problem self-resolves, minimal notifications

### Scenario 2: Persistent Empty Folder
**What Happens:**
- Attempt 1 (0 min): Email sent, retry counter = 1
- Attempt 2 (3 min): Email sent, retry counter = 2
- Attempt 3 (6 min): Email sent, retry counter = 3
- Campaign marked permanently failed
- Processing stops, no more emails

**Result:** Support team alerted, infinite emails prevented

### Scenario 3: Wrong Status Assignment
**What Happens:**
- Campaign set to A1 by mistake (no assets intended)
- Fails 3 times, marked permanently failed
- Admin realizes mistake, changes status to different value
- Campaign no longer appears in A1 search results

**Result:** No reset needed, campaign excluded from processing

## Testing

### Test Retry Logic

1. Create test campaign in DAM with A1 status
2. Ensure Master Assets folder is empty
3. Run A1→A2 script manually 3 times
4. Verify emails received and database state

```bash
# Run 1
python scripts/a1_to_a2_box_uploader.py --auth-pfx-v2

# Check database
PGPASSWORD=ferrero_pass_2025 psql -h localhost -p 5437 -U ferrero_user -d ferrero_tracking -c "SELECT campaign_number, a1_retry_count, a1_permanently_failed FROM campaign_status WHERE status = 'A1';"

# Run 2 (wait 3 minutes or run immediately for testing)
python scripts/a1_to_a2_box_uploader.py --auth-pfx-v2

# Check again
PGPASSWORD=ferrero_pass_2025 psql -h localhost -p 5437 -U ferrero_user -d ferrero_tracking -c "SELECT campaign_number, a1_retry_count, a1_permanently_failed FROM campaign_status WHERE status = 'A1';"

# Run 3
python scripts/a1_to_a2_box_uploader.py --auth-pfx-v2

# Verify permanently failed
PGPASSWORD=ferrero_pass_2025 psql -h localhost -p 5437 -U ferrero_user -d ferrero_tracking -c "SELECT campaign_number, a1_retry_count, a1_permanently_failed, a1_failure_reason FROM campaign_status WHERE a1_permanently_failed = TRUE;"
```

### Test Reset Logic

```bash
# Reset the test campaign
PGPASSWORD=ferrero_pass_2025 psql -h localhost -p 5437 -U ferrero_user -d ferrero_tracking -c "UPDATE campaign_status SET a1_retry_count = 0, a1_permanently_failed = FALSE WHERE campaign_number = 'TEST_CAMPAIGN';"

# Run again
python scripts/a1_to_a2_box_uploader.py --auth-pfx-v2

# Verify it retries
```

## Monitoring

### Dashboard Query: Current Retry Status

```sql
SELECT
    COUNT(*) FILTER (WHERE a1_retry_count = 0) as "No Issues",
    COUNT(*) FILTER (WHERE a1_retry_count = 1) as "Attempt 1",
    COUNT(*) FILTER (WHERE a1_retry_count = 2) as "Attempt 2",
    COUNT(*) FILTER (WHERE a1_retry_count >= 3) as "Permanently Failed"
FROM campaign_status
WHERE status = 'A1';
```

### Alert Query: Campaigns Near Failure

```sql
SELECT campaign_number, campaign_name, a1_retry_count, a1_last_retry_at
FROM campaign_status
WHERE status = 'A1'
  AND a1_retry_count >= 2
  AND a1_permanently_failed = FALSE
ORDER BY a1_retry_count DESC, a1_last_retry_at DESC;
```

---

## Troubleshooting

### Q: Campaign keeps failing even after adding assets
**A:** Check if campaign was marked permanently failed. Reset using SQL command above.

### Q: Want to change from 3 to 5 retry attempts
**A:** Edit `MAX_RETRIES = 3` in `database.py` line ~567. Also update email templates to reflect new maximum.

### Q: How to disable retry logic completely?
**A:** Not recommended, but you can:
1. Set `MAX_RETRIES = 999` (effectively infinite)
2. Or revert to old `a1_to_a2_no_assets` template without retry tracking

### Q: Can I set different retry counts for different campaigns?
**A:** No, it's a global setting. All campaigns use same `MAX_RETRIES` value.

### Q: What if I want to delete permanently failed campaigns from database?
**A:** Don't delete. Instead, change their status to something other than A1. They'll be excluded from processing automatically.

## Future Enhancements

Potential improvements for future versions:

1. **Configurable retry timing:**
   - Instead of relying on cron frequency (3 min)
   - Check `a1_last_retry_at` and skip if too recent
   - Allow exponential backoff (3 min, 10 min, 30 min)

2. **Campaign-specific retry limits:**
   - Add optional `a1_max_retries` column
   - Allow different campaigns to have different thresholds
   - Default to global MAX_RETRIES if not set

3. **Automatic cleanup:**
   - After 30 days, auto-reset permanently failed campaigns
   - Or send weekly digest of stuck campaigns

4. **Webhook notifications:**
   - Send to external system when campaign permanently fails
   - Integrate with ticketing system

5. **Admin UI:**
   - Web interface to view/reset retry status
   - Bulk reset operations
