# StarPunk Troubleshooting Guide
|
||||
|
||||
**Version**: 1.1.1
|
||||
**Last Updated**: 2025-11-25
|
||||
|
||||
This guide helps diagnose and resolve common issues with StarPunk.
|
||||
|
||||
## Quick Diagnostics
|
||||
|
||||
### Check System Health
|
||||
|
||||
```bash
|
||||
# Basic health check
|
||||
curl http://localhost:5000/health
|
||||
|
||||
# Detailed health check (requires authentication)
|
||||
curl -H "Authorization: Bearer YOUR_TOKEN" \
|
||||
http://localhost:5000/health?detailed=true
|
||||
|
||||
# Full diagnostics
|
||||
curl -H "Authorization: Bearer YOUR_TOKEN" \
|
||||
http://localhost:5000/admin/health
|
||||
```
|
||||
|
||||
### Check Logs
|
||||
|
||||
```bash
|
||||
# View recent logs
|
||||
tail -f data/logs/starpunk.log
|
||||
|
||||
# Search for errors
|
||||
grep ERROR data/logs/starpunk.log | tail -20
|
||||
|
||||
# Search for warnings
|
||||
grep WARNING data/logs/starpunk.log | tail -20
|
||||
```
|
||||
|
||||
### Check Database
|
||||
|
||||
```bash
|
||||
# Verify database exists and is accessible
|
||||
ls -lh data/starpunk.db
|
||||
|
||||
# Check database integrity
|
||||
sqlite3 data/starpunk.db "PRAGMA integrity_check;"
|
||||
|
||||
# Check migrations
|
||||
sqlite3 data/starpunk.db "SELECT * FROM schema_migrations;"
|
||||
```
|
||||
|
||||
## Common Issues
|
||||
|
||||
### Application Won't Start
|
||||
|
||||
#### Symptom
|
||||
StarPunk fails to start or crashes immediately.
|
||||
|
||||
#### Possible Causes
|
||||
|
||||
1. **Missing configuration**
|
||||
```bash
|
||||
# Check required environment variables
|
||||
echo $SITE_URL
|
||||
echo $SITE_NAME
|
||||
echo $ADMIN_ME
|
||||
```
|
||||
|
||||
**Solution**: Set all required variables in `.env`:
|
||||
```bash
|
||||
SITE_URL=https://your-domain.com/
|
||||
SITE_NAME=Your Site Name
|
||||
ADMIN_ME=https://your-domain.com/
|
||||
```
|
||||
|
||||
2. **Database locked**
|
||||
```bash
|
||||
# Check for other processes
|
||||
lsof data/starpunk.db
|
||||
```
|
||||
|
||||
**Solution**: Stop other StarPunk instances or wait for lock release
|
||||
|
||||
3. **Permission issues**
|
||||
```bash
|
||||
# Check permissions
|
||||
ls -ld data/
|
||||
ls -l data/starpunk.db
|
||||
```
|
||||
|
||||
**Solution**: Fix permissions:
|
||||
```bash
|
||||
chmod 755 data/
|
||||
chmod 644 data/starpunk.db
|
||||
```
|
||||
|
||||
4. **Missing dependencies**
|
||||
```bash
|
||||
# Re-sync dependencies
|
||||
uv sync
|
||||
```
|
||||
|
||||
### Database Connection Errors
|
||||
|
||||
#### Symptom
|
||||
Errors like "database is locked" or "unable to open database file"
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Check database path**
|
||||
```bash
|
||||
# Verify DATABASE_PATH in config
|
||||
echo $DATABASE_PATH
|
||||
ls -l $DATABASE_PATH
|
||||
```
|
||||
|
||||
2. **Check file permissions**
|
||||
```bash
|
||||
# Database file needs write permission
|
||||
chmod 644 data/starpunk.db
|
||||
chmod 755 data/
|
||||
```
|
||||
|
||||
3. **Check disk space**
|
||||
```bash
|
||||
df -h
|
||||
```
|
||||
|
||||
4. **Check connection pool**
|
||||
```bash
|
||||
# View pool statistics
|
||||
curl http://localhost:5000/admin/metrics | jq '.database.pool'
|
||||
```
|
||||
|
||||
If pool is exhausted, increase `DB_POOL_SIZE`:
|
||||
```bash
|
||||
export DB_POOL_SIZE=10
|
||||
```
|
||||
|
||||
### IndieAuth Login Fails
|
||||
|
||||
#### Symptom
|
||||
Cannot log in to admin interface, redirects fail, or authentication errors.
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Check ADMIN_ME configuration**
|
||||
```bash
|
||||
echo $ADMIN_ME
|
||||
```
|
||||
|
||||
Must be a valid URL that matches your identity.
|
||||
|
||||
2. **Check IndieAuth endpoints**
|
||||
```bash
|
||||
# Verify endpoints are discoverable
|
||||
curl -I $ADMIN_ME | grep Link
|
||||
```
|
||||
|
||||
Should show authorization_endpoint and token_endpoint.
|
||||
|
||||
3. **Check callback URL**
|
||||
- Verify `/auth/callback` is accessible
|
||||
- Check for HTTPS in production
|
||||
- Verify no trailing slash issues
|
||||
|
||||
4. **Check session secret**
|
||||
```bash
|
||||
echo $SESSION_SECRET
|
||||
```
|
||||
|
||||
Must be set and persistent across restarts.
|
||||
|
||||
### RSS Feed Issues
|
||||
|
||||
#### Symptom
|
||||
Feed not displaying, validation errors, or empty feed.
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Check feed endpoint**
|
||||
```bash
|
||||
curl http://localhost:5000/feed.xml | head -50
|
||||
```
|
||||
|
||||
2. **Verify published notes**
|
||||
```bash
|
||||
sqlite3 data/starpunk.db \
|
||||
"SELECT COUNT(*) FROM notes WHERE published=1;"
|
||||
```
|
||||
|
||||
3. **Check feed cache**
|
||||
```bash
|
||||
# Clear cache by restarting
|
||||
# Cache duration controlled by FEED_CACHE_SECONDS
|
||||
```
|
||||
|
||||
4. **Validate feed**
|
||||
```bash
|
||||
curl http://localhost:5000/feed.xml | \
|
||||
xmllint --format - | head -100
|
||||
```
|
||||
|
||||
### Search Not Working
|
||||
|
||||
#### Symptom
|
||||
Search returns no results or errors.
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Check FTS5 availability**
|
||||
```bash
|
||||
sqlite3 data/starpunk.db \
|
||||
"SELECT COUNT(*) FROM notes_fts;"
|
||||
```
|
||||
|
||||
2. **Rebuild search index**
|
||||
```bash
|
||||
uv run python -c "from starpunk.search import rebuild_fts_index; \
|
||||
rebuild_fts_index('data/starpunk.db', 'data')"
|
||||
```
|
||||
|
||||
3. **Check for FTS5 support**
|
||||
```bash
|
||||
sqlite3 data/starpunk.db \
|
||||
"PRAGMA compile_options;" | grep FTS5
|
||||
```
|
||||
|
||||
If not available, StarPunk will fall back to LIKE queries automatically.
|
||||
|
||||
### Performance Issues
|
||||
|
||||
#### Symptom
|
||||
Slow response times, high memory usage, or timeouts.
|
||||
|
||||
#### Diagnostics
|
||||
|
||||
1. **Check performance metrics**
|
||||
```bash
|
||||
curl http://localhost:5000/admin/metrics | jq '.performance'
|
||||
```
|
||||
|
||||
2. **Check database pool**
|
||||
```bash
|
||||
curl http://localhost:5000/admin/metrics | jq '.database.pool'
|
||||
```
|
||||
|
||||
3. **Check system resources**
|
||||
```bash
|
||||
# Memory usage
|
||||
ps aux | grep starpunk
|
||||
|
||||
# Disk usage
|
||||
df -h
|
||||
|
||||
# Open files
|
||||
lsof -p $(pgrep -f starpunk)
|
||||
```
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Increase connection pool**
|
||||
```bash
|
||||
export DB_POOL_SIZE=10
|
||||
```
|
||||
|
||||
2. **Adjust metrics sampling**
|
||||
```bash
|
||||
# Reduce sampling for high-traffic sites
|
||||
export METRICS_SAMPLING_HTTP=0.01 # 1% sampling
|
||||
export METRICS_SAMPLING_RENDER=0.01
|
||||
```
|
||||
|
||||
3. **Increase cache duration**
|
||||
```bash
|
||||
export FEED_CACHE_SECONDS=600 # 10 minutes
|
||||
```
|
||||
|
||||
4. **Check slow queries**
|
||||
```bash
|
||||
grep "SLOW" data/logs/starpunk.log
|
||||
```
|
||||
|
||||
### Log Rotation Not Working
|
||||
|
||||
#### Symptom
|
||||
Log files growing unbounded, disk space issues.
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Check log directory**
|
||||
```bash
|
||||
ls -lh data/logs/
|
||||
```
|
||||
|
||||
2. **Verify log rotation configuration**
|
||||
- RotatingFileHandler configured for 10MB files
|
||||
- Keeps 10 backup files
|
||||
- Automatic rotation on size limit
|
||||
|
||||
3. **Manual log rotation**
|
||||
```bash
|
||||
# Backup and truncate
|
||||
mv data/logs/starpunk.log data/logs/starpunk.log.old
|
||||
touch data/logs/starpunk.log
|
||||
chmod 644 data/logs/starpunk.log
|
||||
```
|
||||
|
||||
4. **Check permissions**
|
||||
```bash
|
||||
ls -l data/logs/
|
||||
chmod 755 data/logs/
|
||||
chmod 644 data/logs/*.log
|
||||
```
|
||||
|
||||
### Metrics Dashboard Not Loading
|
||||
|
||||
#### Symptom
|
||||
Blank dashboard, 404 errors, or JavaScript errors.
|
||||
|
||||
#### Solutions
|
||||
|
||||
1. **Check authentication**
|
||||
- Must be logged in as admin
|
||||
- Navigate to `/admin/dashboard`
|
||||
|
||||
2. **Check JavaScript console**
|
||||
- Open browser developer tools
|
||||
- Look for CDN loading errors
|
||||
- Verify htmx and Chart.js load
|
||||
|
||||
3. **Check network connectivity**
|
||||
```bash
|
||||
# Test CDN access
|
||||
curl -I https://unpkg.com/htmx.org@1.9.10
|
||||
curl -I https://cdn.jsdelivr.net/npm/chart.js@4.4.0/dist/chart.umd.min.js
|
||||
```
|
||||
|
||||
4. **Test metrics endpoint**
|
||||
```bash
|
||||
curl http://localhost:5000/admin/metrics
|
||||
```
|
||||
|
||||
## Log File Locations
|
||||
|
||||
- **Application logs**: `data/logs/starpunk.log`
|
||||
- **Rotated logs**: `data/logs/starpunk.log.1` through `starpunk.log.10`
|
||||
- **Container logs**: `podman logs starpunk` or `docker logs starpunk`
|
||||
- **System logs**: `/var/log/syslog` or `journalctl -u starpunk`
|
||||
|
||||
## Health Check Interpretation
|
||||
|
||||
### Basic Health (`/health`)
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "healthy"
|
||||
}
|
||||
```
|
||||
|
||||
- **healthy**: All systems operational
|
||||
- **unhealthy**: Critical issues detected
|
||||
|
||||
### Detailed Health (`/health?detailed=true`)
|
||||
|
||||
```json
|
||||
{
|
||||
"status": "healthy",
|
||||
"version": "1.1.1",
|
||||
"checks": {
|
||||
"database": {"status": "healthy"},
|
||||
"filesystem": {"status": "healthy"},
|
||||
"fts_index": {"status": "healthy"}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Check each component status individually.
|
||||
|
||||
### Full Diagnostics (`/admin/health`)
|
||||
|
||||
Includes all above plus:
|
||||
- Performance metrics
|
||||
- Database pool statistics
|
||||
- System resource usage
|
||||
- Error budget status
|
||||
|
||||
## Performance Monitoring Tips
|
||||
|
||||
### Normal Metrics
|
||||
|
||||
- **Database queries**: avg < 50ms
|
||||
- **HTTP requests**: avg < 200ms
|
||||
- **Template rendering**: avg < 50ms
|
||||
- **Pool usage**: < 80% connections active
|
||||
|
||||
### Warning Signs
|
||||
|
||||
- **Database**: avg > 100ms consistently
|
||||
- **HTTP**: avg > 500ms
|
||||
- **Pool**: 100% connections active
|
||||
- **Memory**: continuous growth
|
||||
|
||||
### Metrics Sampling
|
||||
|
||||
Adjust sampling rates based on traffic:
|
||||
|
||||
```bash
|
||||
# Low traffic (< 100 req/day)
|
||||
METRICS_SAMPLING_DATABASE=1.0
|
||||
METRICS_SAMPLING_HTTP=1.0
|
||||
METRICS_SAMPLING_RENDER=1.0
|
||||
|
||||
# Medium traffic (100-1000 req/day)
|
||||
METRICS_SAMPLING_DATABASE=1.0
|
||||
METRICS_SAMPLING_HTTP=0.1
|
||||
METRICS_SAMPLING_RENDER=0.1
|
||||
|
||||
# High traffic (> 1000 req/day)
|
||||
METRICS_SAMPLING_DATABASE=0.1
|
||||
METRICS_SAMPLING_HTTP=0.01
|
||||
METRICS_SAMPLING_RENDER=0.01
|
||||
```
|
||||
|
||||
## Database Pool Issues
|
||||
|
||||
### Pool Exhaustion
|
||||
|
||||
**Symptom**: "No available connections" errors
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Increase pool size
|
||||
export DB_POOL_SIZE=10
|
||||
|
||||
# Or reduce request concurrency
|
||||
```
|
||||
|
||||
### Pool Leaks
|
||||
|
||||
**Symptom**: Connections not returned to pool
|
||||
|
||||
**Check**:
|
||||
```bash
|
||||
curl http://localhost:5000/admin/metrics | \
|
||||
jq '.database.pool'
|
||||
```
|
||||
|
||||
Look for high `active_connections` that don't decrease.
|
||||
|
||||
**Solution**: Restart application to reset pool
|
||||
|
||||
