|
|
}
|
|
```
|
|
|
|
## Documentation Gaps
|
|
|
|
### 1. Missing API Documentation
|
|
```dart
|
|
// Need to document:
|
|
|
|
/// Pipes process output.
|
|
///
|
|
/// Example:
|
|
/// ```dart
|
|
/// await process
|
|
/// .pipe('sort')
|
|
/// .pipe('uniq')
|
|
/// .pipeOutput('output.txt');
|
|
/// ```
|
|
Future<ProcessResult> pipe(String command);
|
|
|
|
/// Schedules process execution.
|
|
///
|
|
/// Example:
|
|
/// ```dart
|
|
/// scheduler.daily('backup.sh', '02:00');
|
|
/// scheduler.weekly('cleanup.sh', DateTime.sunday);
|
|
/// scheduler.cron('0 * * * *', 'hourly.sh');
|
|
/// ```
|
|
void schedule(String command, String frequency);
|
|
```
|
|
|
|
### 2. Missing Integration Examples
|
|
```dart
|
|
// Need examples for:
|
|
|
|
// 1. Process Groups
|
|
var group = ProcessGroup();
|
|
group.add('web-server', '--port=8080');
|
|
group.add('worker', '--queue=default');
|
|
await group.start();
|
|
|
|
// 2. Process Recovery
|
|
var recovery = ProcessRecovery(process);
|
|
recovery.onCrash(() async {
|
|
await notifyAdmin('Process crashed');
|
|
await process.restart();
|
|
});
|
|
|
|
// 3. Process Monitoring
|
|
var monitor = ProcessMonitor(process);
|
|
monitor.onHighMemory((usage) async {
|
|
await process.restart();
|
|
await notifyAdmin('High memory usage: $usage');
|
|
});
|
|
```
|
|
|
|
### 3. Missing Test Coverage
|
|
```dart
|
|
// Need tests for:
|
|
|
|
void main() {
|
|
group('Process Pipelines', () {
|
|
test('pipes process output', () async {
|
|
var process = await manager.start('ls');
|
|
var result = await process
|
|
.pipe('sort')
|
|
.pipe('uniq')
|
|
.pipeOutput('output.txt');
|
|
|
|
expect(result.exitCode, equals(0));
|
|
expect(File('output.txt').existsSync(), isTrue);
|
|
});
|
|
});
|
|
|
|
group('Process Scheduling', () {
|
|
test('schedules daily tasks', () async {
|
|
var scheduler = ProcessScheduler();
|
|
scheduler.daily('backup.sh', '02:00');
|
|
|
|
var nextRun = scheduler.getNextRun('backup.sh');
|
|
expect(nextRun.hour, equals(2));
|
|
});
|
|
});
|
|
}
|
|
```

### 1. Getting Started
|
|
Before implementing process features:
|
|
1. Review [Getting Started Guide](getting_started.md)
|
|
2. Check [Laravel Compatibility Roadmap](laravel_compatibility_roadmap.md)
|
|
3. Follow [Testing Guide](testing_guide.md)
|
|
4. Use [Foundation Integration Guide](foundation_integration_guide.md)
|
|
5. Review [Process Package Specification](process_package_specification.md)
|
|
6. Review [Events Package Specification](events_package_specification.md)
|
|
7. Review [Queue Package Specification](queue_package_specification.md)
|
|
|
|
### 2. Implementation Process
|
|
For each process feature:
|
|
1. Write tests following [Testing Guide](testing_guide.md)
|
|
2. Implement following Laravel patterns
|
|
3. Document following [Getting Started Guide](getting_started.md#documentation)
|
|
4. Integrate following [Foundation Integration Guide](foundation_integration_guide.md)
|
|
|
|
### 3. Quality Requirements
|
|
All implementations must:
|
|
1. Pass all tests (see [Testing Guide](testing_guide.md))
|
|
2. Meet Laravel compatibility requirements
|
|
3. Follow integration patterns (see [Foundation Integration Guide](foundation_integration_guide.md))
|
|
4. Match specifications in [Process Package Specification](process_package_specification.md)
|
|
|
|
### 4. Integration Considerations
|
|
When implementing process features:
|
|
1. Follow patterns in [Foundation Integration Guide](foundation_integration_guide.md)
|
|
2. Ensure Laravel compatibility per [Laravel Compatibility Roadmap](laravel_compatibility_roadmap.md)
|
|
3. Use testing approaches from [Testing Guide](testing_guide.md)
|
|
4. Follow development setup in [Getting Started Guide](getting_started.md)
|
|
|
|
### 5. Performance Guidelines
|
|
Process system must:
|
|
1. Handle concurrent processes efficiently
|
|
2. Manage system resources
|
|
3. Support process pooling
|
|
4. Scale with process count
|
|
5. Meet performance targets in [Laravel Compatibility Roadmap](laravel_compatibility_roadmap.md#performance-benchmarks)
|
|
|
|
### 6. Testing Requirements
|
|
Process tests must:
|
|
1. Cover all process operations
|
|
2. Test concurrent execution
|
|
3. Verify event handling
|
|
4. Check resource cleanup
|
|
5. Follow patterns in [Testing Guide](testing_guide.md)
|
|
|
|
### 7. Documentation Requirements
|
|
Process documentation must:
|
|
1. Explain process patterns
|
|
2. Show pipeline examples
|
|
3. Cover error handling
|
|
4. Include performance tips
|
|
5. Follow standards in [Getting Started Guide](getting_started.md#documentation)
