图2是本公开另一实施例提出的分区表更新方法的流程示意图；
图3是本公开实施例中分区表更新场景示意图；
图4是本公开一实施例提出的分区表更新装置的结构示意图；
图5是本公开另一实施例提出的分区表更新装置的结构示意图；
图6示出了适于用来实现本公开实施方式的示例性电子设备的框图。
具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本公开，而不能理解为对本公开的限制。相反，本公开的实施例包括落入所附加权利要求书的 精神和内涵范围内的所有变化、修改和等同物。
图1是本公开一实施例提出的分区表更新方法的流程示意图。
需要说明的是，本实施例的分区表更新方法的执行主体为分区表更新装置，该装置可以由软件和/或硬件的方式实现，该装置可以配置在电子设备中，对此不做限制。
电子设备，是一种经由通信设施向其他设备发送数据或接收其他设备数据的设备，也即是说，该电子设备可以例如为能够进行网络通信连接的终端设备、计算机设备等，对此不做限制。
如图1所示，该分区表更新方法，包括：
S101：确认电子设备处于***升级模式，检测第一操作***的启动状态信息。
其中，***升级模式，例如，基于空中下载技术(Over the Air Technology，OTA)的***升级模式，也可以被称为在线升级模式。
可以理解的是，在电子设备处于***升级模式进行***升级时，分区表的更新存在风险，而如果分区表未能成功更新，则会影响所升级的操作***的启动，其中，所升级的操作***，可以被称为第一操作***，则本公开实施例中支持在电子设备处于***升级模式时，对所升级的第一操作***的启动状态进行动态监测，得到描述第一操作***启动状态的信息作为启动状态信息，启动状态信息例如，启动耗时、启动是否成功等等，对此不做限制。
其中，操作***，是指管理计算机硬件与软件资源的计算机程序，操作***可以处理如管理与配置内存、决定***资源供需的优先次序、控制输入设备与输出设备、操作网络与管理文件***等基本事务。同时操作***也提供一个供用户与***交互的操作界面。
举例而言，如果检测到电子设备处于***升级模式，则可以在对***升级得到第一操作***之后，基于所更新分区表对第一操作***进行启动控制，并在第一操作***启动的过程中，检测第一操作***的启动状态信息，比如，可以获取启动所需配置文件，基于该配置文件分析启动状态信息，或者，还可以获取第一操作***启动的日志信息，基于该日志信息动态分析启动状态信息，对此不做限制。
可选地，一些实施例中，可以对初始分区表进行更新，得到目标分区表，并根据目标分区表启动第一操作***，以及在启动第一操作***的过程中，检测第一操作***的启动状态信息，由此，实现对第一操作***的启动过程进行动态监测，如果第一操作***能够正常启动，则可以控制电子设备进入正常的使用流程，而如果第一操作***不能够正常启动，可以触发执行后续步骤。
其中，第一次对初始分区表进行更新所得分区表，可以被称为目标分区表，而后，可以触发基于目标分区表启动第一操作***，并在启动第一操作***的过程中，对第一操作***的启动过程进行动态监测。
S102：确认启动状态信息指示第一操作***满足设定启动事件，获取第二操作***的初始分区表，其中，第一操作***的***类型和第二操作***的***类型相同。
本公开实施例在确认电子设备处于***升级模式，检测第一操作***的启动状态信息之后，可以对启动状态信息进行分析处理，以确定第一操作***在启动过程中是否发生设定启动事件，该设定启动事件，是指第一操作***未能正常启动的事件。
当确定启动状态信息指示第一操作***满足设定启动事件时，可以获取第二操作***的初始分区表，而后，基于第二操作***的初始分区表重新进行分区表更新，以基于所得分区表重启第一操作***。
其中，与第二操作***对应的分区表，可以被称为初始分区表，而分区表，是指将大表的数据分成称为分区的许多小的子集。另外，分区表的种类划分主要有：Range(范围)、List(列表)和Hash(散列)分区。划分依据主要是根据其表内部属性。同时，分区表可以创建其独特的分区索引。倘若硬盘丢失了分区表，数据就无法按顺序读取和写入，导致无法操作。
其中，第一操作***的***类型和第二操作***的***类型相同，也即是说，***类型，用于描述该操作***的类型、型号、名称等，第二操作***的版本可以比第一操作***的版本低，比如，第二操作***，可以是***升级之前旧版本的操作***，相应的，第一操作***是***升级后新版本的操作***。
也即是说，本公开实施例中，如果确定第一操作***满足设定启动事件，即表明升级所得第一操作***未能正常启动，此时，为了有效弥补分区表未能成功更新所引入的启动损失，可以获取第二操作***的初始分区表，以触发后续重新更新初始分区表的过程。
S103：根据初始分区表启动第二操作***，并对初始分区表更新得到更新分区表，其中，更新分区表所指示分区用于挂载启动后第一操作***。
上述在确认启动状态信息指示第一操作***满足设定启动事件，获取第二操作***的初始分区表之后，可以基于初始分区表启动第二操作***，由于第一操作***未能成功启动，则可以先启动旧版本的第二操作***，以便于重新对初始分区表进行更新，则再次对初始分区表进行更新所得分区表，可以被称为更新分区表，该更新分区表所指示分区用于挂载启动后第一操作***。
可选地，一些实施例中，在对初始分区表更新得到更新分区表之后，还可以根据更新分区表重启第一操作***，也即是说，在第一次对第一操作***启动失败之后，可以基于初始分区表启动升级之前的第二操作***，以保证电子设备能够被正常使用，而后，再一次触发对初始分区表进行更新，得到更新分区表，并基于该更新分区表重启第一操作***，以挂载启动后第一操作***。
由此，有效地保证初始分区表的升级成功率，在升级成功后，根据更新分区表启动分区的识别，以正常启动第一操作***，保证初始分区表能正确地被更新，有效降低电子设备的维修时间成本和经济成本。
本实施例中，通过确认电子设备处于***升级模式，检测第一操作***的启动状态信息，并确认启动状态信息指示第一操作***满足设定启动事件，获取第二操作***的初始分区表，根据初始分区表启动第二操作***，并对初始分区表更新得到更新分区表，能够有效提升分区表更新成功率。
图2是本公开另一实施例提出的分区表更新方法的流程示意图。
如图2所示，该分区表更新方法，包括：
S201：获取分区表生成包，其中，分区表生成包中包括：至少两份初始分区表，和与初始分区表对应的目标分区表。
其中，通过在对操作***进行OTA时，可以每次将每份分区表在指定位置备份保存(比如，可以至少备份两份)，如果分区表更新失败，则仍然能够保证获得一份完整的分区表，有效避免分区表更新异常而不完整的风险，另外，在制作分区表时可以将要更新至的分区表(目标分区表)，和原分区表(初始分区表)制作在同一个分区表生成包中，以便于后续快速获取到一份完整的分区表。
其中，所获取分区表生成包，被用于在更新电子设备中的分区表时作为参考，该分区表生成包，可 以是从云端服务器下载得到的，对此不做限制。
S202：将初始分区表更新为目标分区表。
上述在获取分区表生成包后，可以从分区表生成包中解析出与初始分区表对应的目标分区表，而后，可以执行对初始分区表进行更新的步骤，将初始分区表更新为目标分区表。
S203：根据目标分区表启动第一操作***。
上述在将初始分区表更新为目标分区表之后，可以直接根据目标分区表启动第一操作***，并动态地对第一操作***的启动状态信息进行监测。
S204：在启动第一操作***的过程中，检测第一操作***的启动状态信息。
可选地，一些实施例中，在检测第一操作***的启动状态信息时，可以确定第一操作***在启动过程中所调用模块的信息，将所调用模块的信息作为启动状态信息，则在所调用模块的信息匹配至少一个候选模块信息，则确定启动状态信息指示第一操作***满足设定启动事件，其中，候选模块信息是预先设置，由于操作***对各个模块的调用情况，能够有效代表操作***是否能够正常启动，因此，当基于所调用模块的情况来识别启动状态信息时，能够提升启动状态信息检测的准确率。
其中，候选模块是指第一操作***在异常启动情况下所调用模块，例如模块A、模块B、模块C，则用于描述所调用模块的信息，可以被称为候选模块信息，例如所调用模块的名称、类型、标识、功能等。
如果第一操作***在实际启动过程中，调用了模块A、模块B、模块C中的至少一个模块，则可以确定第一操作***可能存在异常启动情况，即表明第一操作***满足设定启动事件。
可选地，另一些实施例中，在检测第一操作***的启动状态信息，还可以获取第一操作***在启动过程中所识别标记，将所识别标记的内容作为启动状态信息，则在所识别标记的内容匹配至少一个候选标记内容，则确定启动状态信息指示第一操作***满足设定启动事件，其中，候选标记内容是预先设置，从而能够有效提升第一操作***是否满足设定启动事件的判定的灵活性，提升判定方法的实用性。
其中，候选标记内容是指第一操作***在异常启动情况下所访问标记的内容，例如标记1、标记2、标记3，则用于描述所访问标记实际的标记内容，可以被称为候选标记内容，例如所访问标记的名称、类型等。
如果第一操作***在实际启动过程中，访问了标记1、标记2、标记3中的至少一个标记的内容，则可以确定第一操作***可能存在异常启动情况，即表明第一操作***满足设定启动事件。
S205：确认启动状态信息指示第一操作***满足设定启动事件，从分区表生成包中读取初始分区表，并将所读取的初始分区表作为第二操作***的初始分区表。
其中，第一操作***的***类型和第二操作***的***类型相同，也即是说，***类型，用于描述该操作***的类型、型号、名称等，第二操作***的版本可以比第一操作***的版本低，比如，第二操作***，可以是***升级之前旧版本的操作***，相应的，第一操作***是***升级后新版本的操作***。
上述在确认启动状态信息指示第一操作***满足设定启动事件时，可以从分区表生成包中读取初始分区表，并将所读取的初始分区表作为第二操作***的初始分区表，从而能够有效提升初始分区表的获取效率，提升整体的分区表更新恢复效率，还能够保证所获得初始分区表的完整性。
其中，分区表生成包中的初始分区表的数量可以是两份或者多份，对于至少两份初始分区表的存储，可以针对每份初始分区表预先配置存储地址，该存储地址，描述初始分区表对应于分区表生成包中的存储位置，还可以确定初始分区表的存储位置与目标分区表的存储位置之间的地址偏移量，并基于地址偏移量对不同初始分区表进行标记处理，以便于快速地读取到完整的初始分区表。
可选地，一些实施例中，分区表生成包还包括：每一个初始分区表的存储地址与目标分区表的存储地址之间的地址偏移量，其中，从分区表生成包中读取初始分区表，并将所读取的初始分区表作为第二操作***的初始分区表，可以是根据目标分区表的存储地址和地址偏移量，确定参考存储地址，并从分区表生成包中读取与参考存储地址所对应初始分区表，以及将所对应初始分区表作为第二操作***的初始分区表。
其中，基于目标分区表的存储地址和地址偏移量所确定的存储地址，可以被称为参考存储地址，该参考存储地址可以是计算所得的初始分区表在分区表生成包中的存储地址，而目标分区表的存储地址，指示目标分区表在分区表生成包中的存储地址。
上述在根据目标分区表的存储地址和地址偏移量，确定参考存储地址，可以直接从分区表生成包中确定与参考存储地址所匹配初始分区表作为第二操作***的初始分区表。
S206：根据初始分区表启动第二操作***，并对初始分区表更新得到更新分区表，其中，更新分区表所指示分区用于挂载启动后第一操作***。
上述在确认启动状态信息指示第一操作***满足设定启动事件，获取第二操作***的初始分区表之后，可以基于初始分区表启动第二操作***，由于第一操作***未能成功启动，则可以先启动旧版本的第二操作***，以便于重新对初始分区表进行更新，则再次对初始分区表进行更新所得分区表，可以被称为更新分区表，该更新分区表所指示分区用于挂载启动后第一操作***。
本实施例中，通过确认电子设备处于***升级模式，检测第一操作***的启动状态信息，并确认启动状态信息指示第一操作***满足设定启动事件，获取第二操作***的初始分区表，根据初始分区表启动第二操作***，并对初始分区表更新得到更新分区表，能够有效提升分区表更新成功率。通过获取分区表生成包，其中，分区表生成包中包括：至少两份初始分区表，和与初始分区表对应的目标分区表，将初始分区表更新为目标分区表，根据目标分区表启动第一操作***，由于将要更新至的分区表(目标分区表)，和原分区表(初始分区表)制作在同一个分区表生成包中，以便于后续快速获取到一份完整的分区表，还可以实现对第一操作***的启动过程进行动态监测，不会对第一操作***的正常启动过程带入影响，提升第一操作***过程和分区表更新修复过程的连贯性。在确认启动状态信息指示第一操作***满足设定启动事件时，可以从分区表生成包中读取初始分区表，并将所读取的初始分区表作为第二操作***的初始分区表，从而能够有效提升初始分区表的获取效率，提升整体的分区表更新恢复效率，还能够保证所获得初始分区表的完整性。
如图3所示，图3是本公开实施例中分区表更新场景示意图，在对操作***进行OTA时，将目标分区表和初始分区表制作在同一个分区表生成包中，并将分区表生成发送至待更新分区表的电子设备，电子设备的第一操作***在启动过程中，如果检测到无法正常启动，则表明初始分区表更新失败，可以触发切换至另一个分区重新启动，以保证成功启动，保障安全性，使得电子设备可以维持正常启动，由于保留了初始分区表，使得在更新为目标分区表之后，还能够恢复至初始分区表，可以有效解决相关技 术中电子设备的第一操作***启动时，由于分区表更新不成功导致***找不到引导启动逻辑而启动失败的技术问题。图3中的A相当于只读存储器(Read-Only Memory，ROM)A，B相当于只读存储器B，选择dtb(分区表)，即表示选择分区表，如果更新了初始分区表，比如，初始分区表中指示A和B大小相同，而目标分区表指示A和B大小不相同，第一操作***在启动过程中时，经由目标分区表访问A，或者经由目标分区表访问B，目标分区表存放能够访问A的起始地址，或者存放能够访问B的起始地址，本公开实施例中把初始分区表和目标分区表烧录在分区表生成包中，对初始分区表进行多份备份保存，目标分区表存放访问B的起始地址，每份初始分区表的存储位置与目标分区表的存储位置相差一个地址偏移量，如果访问B的路径失败，则可以根据地址偏移量定位分区表生成包中所备份的初始分区表，以此保证电子设备的操作***能够正常启动，正常启动之后，可以重新更新初始分区表得到更新分区表。保存reserved(dtb)表示分区表(初始分区表或者目标分区表)的存储地址，在操作***(第一操作***或者第二操作***)启动时，经过reserved(dtb)指示的存储地址、启动装载bootloader的位置，私有化private的位置、操作***(第一操作***或者第二操作***)相关文件的位置。
