When the SA process and the SAMGR process perform Binder communication, the proxy object of the SAMGR process needs to be obtained to perform the Binder communication. Common system capabilities include package management services, imprecise delay task scheduling services, distributed task scheduling services, and telephone services. All these system capabilities will be registered with the SAMGR process, so the SAMGR process maintains a list of all system capabilities in the HarmonyOS system. If any application program wants to use these system capabilities, it must first request the reference of these system capabilities from the SAMGR process, so as to establish a connection with these system capabilities.

当SAMGR进程崩溃后，新启动的应用程序无法通过SAMGR进程获取到其所需要使用到的系统能力，该新启动的应用程序将会出现闪退的情况。可以通过采用本申请实施例提供的系统服务恢复方法，可以快速地控制SA进程中的本地管理者把SA进程中的系统能力注册到重新启动后的SAMGR进程中，以恢复电子设备100的系统服务，使得不再需要重新启动电子设备100，也可以快速地恢复电子设备100对外提供服务的能力，提高了系统服务恢的恢复效率，以及提高了用户的使用体验。When the SAMGR process crashes, the newly started application program cannot obtain the system capabilities it needs to use through the SAMGR process, and the newly started application program will crash.

本申请实施例中，当SAMGR进程崩溃时，守护进程通过Binder驱动程序监听到SAMGR进程的死亡通知信息，这时，电子设备100将控制守护进程触发SAMGR进程的重启指令，以重新启动SAMGR进程。在SAMGR进程重新启动后，Binder驱动程序将与SAMGR进程建立Binder通信，使得SA进程中的本地管理者可以通过SAMGR进程的代理对象进行Binder通信。In the embodiment of the present application, when the SAMGR process crashes, the daemon process monitors the death notification information of the SAMGR process through the Binder driver. At this time, the electronic device 100 will control the daemon process to trigger a restart command of the SAMGR process to restart the SAMGR process. After the SAMGR process is restarted, the Binder driver will establish Binder communication with the SAMGR process, so that the local manager in the SA process can perform Binder communication through the proxy object of the SAMGR process.

S201、电子设备100控制所述SAMGR进程重启。S201. The electronic device 100 controls the restart of the SAMGR process.

本申请实施例中，电子设备100通过守护进程控制所述SAMGR进程重启。所述守护进程用于启动SAMGR进程，以及守护并监视SAMGR进程。在SAMGR进程崩溃时，守护进程将会接收到一个进程终止SIGCHLD信号，该SIGCHLD信号用于指示所述守护进程触发SAMGR进程的重启指令，使得电子设备100根据该重启指令重新启动SAMGR进程。即在步骤S201之前，包括：In the embodiment of the present application, the electronic device 100 controls the restart of the SAMGR process through a daemon process. The daemon process is used to start the SAMGR process, and guard and monitor the SAMGR process. When the SAMGR process crashes, the daemon process will receive a process termination SIGCHLD signal, and the SIGCHLD signal is used to instruct the daemon process to trigger a restart instruction of the SAMGR process, so that the electronic device 100 restarts the SAMGR process according to the restart instruction. That is, before step S201, including:

当守护进程监听到所述SAMGR进程的死亡通知信息时，电子设备100控制所述守护进程触发所述SAMGR进程的重启指令。When the daemon process detects the death notification information of the SAMGR process, the electronic device 100 controls the daemon process to trigger a restart instruction of the SAMGR process.

本申请实施例中，SA记录信息中记录有SA进程中的系统能力的相关信息，比如系统能力的编号、系统能力的代理对象等。在电子设备100控制SAMGR进程的代理对象，向SAMGR进程发送SA记录信息后，本地管理者实现了把SA进程中的系统能力注册到SAMGR进程中的目的。In this embodiment of the present application, information related to system capabilities in the SA process is recorded in the SA record information, such as system capability numbers, system capability proxy objects, and the like. After the electronic device 100 controls the proxy object of the SAMGR process and sends the SA record information to the SAMGR process, the local administrator realizes the purpose of registering the system capabilities in the SA process into the SAMGR process.

可以理解的是，在控制本地管理者通过SAMGR进程的代理对象，把SA进程中的系统能力注册到所述SAMGR进程中，是通过控制本地管理者通过SAMGR进程的代理对象，向所述SAMGR进程发送系统能力SA记录信息，以使得本地管理者可以把SA进程中的系统能力注册到所述SAMGR进程中。在SAMGR进程接收到本地管理者发送的SA记录信息后，SAMGR进程中将记录有相应系统能力的编号，以及相应系统能力的代理对象等，从而使得应用程序在通过SAMGR进程获取其所需要使用的系统能力时，可以通过该系统能力的代理对象获取到该系统能力的编号，实现应用程序调用该系统能力的目的。It can be understood that, when controlling the local manager to register the system capabilities in the SA process into the SAMGR process through the proxy object of the SAMGR process, it is by controlling the local manager to pass the proxy object of the SAMGR process to the SAMGR process Send the system capability SA record information, so that the local administrator can register the system capability in the SA process into the SAMGR process. After the SAMGR process receives the SA record information sent by the local administrator, the SAMGR process will record the number of the corresponding system capability and the proxy object of the corresponding system capability, so that the application can obtain the information it needs to use through the SAMGR process. When using a system capability, the serial number of the system capability can be obtained through the proxy object of the system capability, so as to achieve the purpose of calling the system capability by the application program.

本申请实施例中通过控制系统能力SA进程中的本地管理者获取SAMGR进程的代理对象，再通过该SAMGR进程的代理对象把SA进程中的系统能力注册到SAMGR进程中以恢复系统记录，从而使得采用本申请实施例提供的系统恢复方法的电子设备100在SAMGR进程崩溃后，不再需要重新启动电子设备，而仅是启动崩溃的SAMGR进程，降低了系统服务恢复所需要的时长，提高了系统服务恢复的效率。In the embodiment of the present application, the local manager in the control system capability SA process obtains the proxy object of the SAMGR process, and then registers the system capability in the SA process into the SAMGR process through the proxy object of the SAMGR process to restore the system record, so that The electronic device 100 using the system recovery method provided by the embodiment of the present application no longer needs to restart the electronic device after the SAMGR process crashes, but only starts the collapsed SAMGR process, which reduces the time required for system service recovery and improves the system performance.
