  alarm_name          = "sway-builder-high-cpu"
  comparison_operator = "GreaterThanThreshold"
  evaluation_periods  = 2
  metric_name         = "CPUUtilization"
  namespace           = "AWS/EC2"
  period              = 120

健康检查端点

// 健康检查实现
#include <stdio.h>
#include <unistd.h>
#include <sys/socket.h>

#define HEALTH_CHECK_PORT 8080

int start_health_check_server() {
    int sockfd = socket(AF_INET, SOCK_STREAM, 0);
    // 绑定端口和启动监听
    return 0;
}

void health_check_handler() {
    // 检查关键组件状态
    check_wayland_compositor();
    check_input_devices();
    check_output_configuration();
    
    // 返回JSON格式的健康状态
    printf("HTTP/1.1 200 OK\r\n");
    printf("Content-Type: application/json\r\n\r\n");
    printf("{\"status\":\"healthy\",\"timestamp\":%ld}\n", time(NULL));
}

总结与最佳实践

通过实施完整的CI/CD流水线，Sway项目能够实现：

自动化构建：支持多平台、多配置的并行构建
全面测试：从单元测试到端到端测试的完整覆盖
质量保障：通过静态分析和代码规范检查确保代码质量
快速部署：容器化部署和自动化回滚机制
持续监控：实时性能监控和告警系统

这种DevOps实践不仅提高了开发效率，更重要的是确保了Wayland合成器这一关键系统组件的稳定性和可靠性。对于其他图形相关的开源项目，Sway的CI/CD实践提供了宝贵的参考价值。

提示：本文介绍的CI/CD实践需要根据实际项目需求进行调整。建议从基础的单机构建开始，逐步扩展到完整的流水线。记得定期审查和优化你的自动化流程，确保它们始终符合项目的发展需求。
