用于应用程序在发生 PHM 监控错误时提供并执行恢复措施。

抽象类 ara::phm::RecoveryAction 使应用程序能够为 Platform Health Management 提供应用特定的恢复措施 [SWS_PHM_01141]。实例化之后，调用 Offer() 会使 Phm-Daemon 处于准备接收状态，从而在检测到监控错误时调用重写的成员函数 RecoveryHandler [SWS_PHM_01143]。如果错误无法在应用程序端消除，系统将通过触发看门狗进行升级。出于安全原因，复制和移动操作被完全禁止，并且诸如 Offer() 等管理调用不是线程安全的。

上下文

类 ara::phm::RecoveryAction 是 AUTOSAR Adaptive Platform 的 Platform Health Management（PHM）模块中的抽象基类。它用作功能性应用程序的标准化接口，以提供特定的恢复和错误处理措施，这些措施在检测到监控错误时由 PHM 触发。

主要的交互方包括：

  • 派生应用程序组件：解释：这通常应当位于 State Management 中，因为后者负责协调的系统响应，并在错误上下文中被直接提及。 问题 Q-714ff81a33aa3e92 (未决)应用程序通过重写方法 RecoveryHandler [SWS_PHM_01142] 来实现应用特定的错误消除。
  • Phm-Daemon：通过 Offer [SWS_PHM_01143] 管理恢复操作的注册，并在确定存在错误时控制已注册处理程序的调用 [SWS_PHM_01142]。
  • 看门狗：如果应用程序端的恢复无法成功执行，PHM 将接管进一步的错误处理，并触发看门狗以提供安全保障 [SWS_PHM_01142]。

与 AUTOSAR 模型的逻辑链接在实例化时通过 ara::core::InstanceSpecifier 进行，该说明符必须引用 PhmRecoveryAction 接口的 PPortPrototype [SWS_PHM_01141]。

生命周期

实例通过显式构造函数在传递匹配的 Instance-Specifier 的情况下创建 [SWS_PHM_01141]。该构造函数是线程安全（thread-safe）且异常安全（noexcept）的。

由于 RecoveryAction 与特定端口强绑定，因此复制和移动操作被完全禁止：复制构造函数 [SWS_PHM_01150] 和复制赋值运算符 [SWS_PHM_01152] 均已删除（= delete）。同样，移动构造函数 [SWS_PHM_01149] 和移动赋值运算符 [SWS_PHM_01151] 也已删除。规范对此给出的理由是，在提供实例之后进行移动可能会导致 RecoveryHandler 在派生类完全构造之前被调用，从而引发未定义行为或未处理的异常，并危及系统安全 [SWS_PHM_01149]、[SWS_PHM_01151]。

生命周期包含两个不同的状态：

  • 未提供：紧接着构造之后以及调用 StopOffer [SWS_PHM_01144] 之后，实例处于非活动状态。禁止调用 RecoveryHandler。
  • 已提供：通过调用 Offer() [SWS_PHM_01143]，操作在 Phm-Daemon 中被激活并启用处理程序调用。

对象通过虚析构函数释放 [SWS_PHM_01145]。关于并发性，构造函数和 RecoveryHandler 被指定为线程安全，而 Offer()、StopOffer() 和析构函数不是线程安全（not thread-safe）的 [SWS_PHM_01141]、[SWS_PHM_01142]、[SWS_PHM_01143]、[SWS_PHM_01144]、[SWS_PHM_01145]。解释：在实践中，销毁实例之前应当始终需要调用 StopOffer()，以在对象拆卸过程中可靠地排除异步处理程序调用。 问题 Q-a1f47898bed925fd (未决)

使用路径

典型使用划分为固定的调用序列：

  1. 定义实现纯虚成员函数 RecoveryHandler 的派生类 [SWS_PHM_01142]。
  2. 在指定 Instance-Specifier [SWS_PHM_01141] 的情况下实例化派生对象。
  3. 调用 Offer()，以便向 Phm-Daemon 提供恢复操作 [SWS_PHM_01143]。
  4. 对错误作出响应：PHM 检测到错误时，会调用 RecoveryHandler(executionError, supervision) [SWS_PHM_01142]。该方法提供 ara::core::Future<void>，通过它报告错误消除的结果。
  5. 一旦实例不再需要服务恢复操作，便调用 StopOffer() [SWS_PHM_01144]。
  6. 通过析构函数 [SWS_PHM_01145] 销毁对象。

错误场景

在模型配置和运行的范围内，必须考虑特定的错误条件：

  • 构造时的模型与验证违规 [SWS_PHM_01141]：
    • AraNotInitializedViolation：在实例化之前未初始化 ARA 运行时环境。
    • InstanceSpecifierMappingIntegrityViolation：Instance-Specifier 在模型中无法解析或未引用 PortPrototype。
    • PortInterfaceMappingViolation：通过 RecoveryNotificationToPPortPrototypeMapping 引用的端口原型未由 PhmSupervisionRecoveryNotificationInterface 类型化。
    • ProcessMappingViolation：在运行时不存在针对 Instance-Ref 适当建模的进程。
    • InstanceSpecifierAlreadyInUseViolation：Instance-Specifier 已在当前进程中使用。
  • 提供时的通信错误 [SWS_PHM_01143]： 若与 Phm-Daemon 的通信失败，Offer() 将提供带有错误代码 PhmErrc::kOfferFailed 的结果。
  • 恢复中不可消除的错误 [SWS_PHM_01142]： 若 State Management 无法解决报告的错误，由 RecoveryHandler 返回的 Future 将返回错误 PhmErrc::kSMCanNotHandleRecovery。随后 Platform Health Management 介入并触发看门狗。

无参数方法Offer属于类ara::phm::RecoveryAction，并通过头文件ara/phm/recovery_action.h包含[SWS_PHM_01143]。其目的是向 Platform Health Management (PHM) 提供服务，以便后续能够调用RecoveryHandler [SWS_PHM_01143]。该调用为同步执行且不接受任何参数[SWS_PHM_01143]。

执行结果作为ara::core::Result<void>返回[SWS_PHM_01143]。在无错误状态下，此Result为空。如果与 PHM 守护进程的通信失败，则无法提供该服务，且函数将返回带有回滚语义的错误代码PhmErrc::kOfferFailed [SWS_PHM_01143]。

在执行安全性方面，该方法被指定为noexcept且具备异常安全性（exception safe）[SWS_PHM_01143]。但其明确定义为非线程安全（not thread-safe）[SWS_PHM_01143]。

在系统体系中，与错误处理存在直接耦合：类ara::phm::RecoveryAction的RecoveryHandler用于对执行错误（ara::exec::ExecutionErrorEvent）和监控错误（TypeOfSupervision）作出响应[SWS_PHM_01142]。只有在先前通过RecoveryAction::Offer显式使能激活后，PHM 才能调用该处理程序[SWS_PHM_01142]。

类 ara::phm::RecoveryAction 的方法 StopOffer 用于停用关联的 RecoveryHandler 的执行 [SWS_PHM_01144]。它在头文件 ara/phm/recovery_action.h 中声明 [SWS_PHM_01144]。

用法与语义

该函数的签名具有 void StopOffer() noexcept;，不接受任何参数且不返回返回值 [SWS_PHM_01144]。通过此调用，应用程序向平台健康管理（PHM）发出信号，表明不再应调用该处理程序 [SWS_PHM_01144]。该调用同步执行；正在运行的处理程序实例预计会在停用之前或停用时完成（Interpretation）。 问题 Q-a333b1e2f0634ed1 (未决)

错误处理与并发

  • Exception-Sicherheit：该操作被声明为 noexcept，并被视为完全异常安全；不存在错误码或异常 [SWS_PHM_01144]。
  • Thread-Sicherheit：该方法被明确指定为 not thread-safe [SWS_PHM_01144]。因此，在同一个 RecoveryAction 实例上的并发调用需要调用方进行外部同步。

RecoveryAction & operator= (RecoveryAction &&ra)=delete;

The move assignment operator for the RecoveryAction shall not be used. Rationale: Using the move assignment after a RecoveryAction instance has been offered may result in premature invocation of RecoveryHandler before the derived class is fully constructed. This can lead to undefined behavior or unhandled exceptions, compromising system stability and safety.
