Description

升级包的生成方法、安装方法、设备及存储介质
本申请要求于2022年8月17日提交到国家知识产权局、申请号为202210988967.X、申请名称为“升级包的生成方法、安装方法、设备及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，特别涉及一种升级包的生成方法、安装方法、设备及存储介质。
背景技术
手机、平板电脑、可穿戴设备等终端设备的系统或软件可以在供应商发布新版本后进行升级。目前的升级方法中主要采用的是单包升级策略，具体为，终端设备发起一次软件版本检测，服务器向该终端设备返回一个下载路径，以便终端设备根据该下载路径获得一个升级包，进而根据该升级包进行版本升级。
相关技术中，为了节省服务器的存储资源和终端设备下载升级包的时间，且降低开发成本，升级包通常为相邻两个版本之间的差分文件。比如，在制作系统或软件等待升级对象的升级包时，可以先获取待升级对象的第一安装包和第二安装包，第二安装包的版本高于第一安装包的版本。然后，对第一安装包和第二安装包进行差分处理，得到差分文件，将差分文件打包到升级包中。终端设备获取到该升级包后，即可根据该升级包和存储的第一安装包进行还原处理，得到第二安装包，然后通过安装第二安装包实现版本升级。
但是，通过对第一安装包和第二安装包整体进行差分处理得到的升级包的数据量仍然较大，导致终端设备花费的下载时间较长，且要求终端设备的存储资源足够大，以满足升级包的下载和安装需求。
发明内容
本申请提供了一种升级包的生成方法、安装方法、设备及存储介质，可以在较大程度上减小升级包的数据量，生成数据量相对较小的升级包，节省升级包的下载时间，以及降低对终端设备的存储资源的要求。所述技术方案如下：
第一方面，提供了一种升级包的生成方法，应用于第一设备中，所述方法包括：
获取旧版本的安装包和新版本的安装包，对新旧版本的安装包分别进行切片，得到旧版本的安装包对应的第一切片序列，以及新版本的安装包对应的第二切片序列。第二切片序列中与第一切片序列中排序相同的切片组成一个切片对，第二切片序列中的多个切片与第一切片序列中的多个切片组成多个切片对。然后，根据多个切片对中的每个切片对的数据相似度对每个切片对进行数据处理，得到每个切片对对应的升级包数据，数据处理至少包括跳过处理、异或处理或差分处理。之后，根据多个切片对中的每个切片对的切片序号、以及每个切片对对应的数据处理类型和升级包数据，生成升级包，升级包包括多个切片序号对应的升级包数据以及每个切片序号对应的数据 处理类型信息。
其中，跳过处理是指不对对应切片对的数据进行处理，通过跳过处理得到的切片对对应的升级包数据为空。升级包中对应数据处理类型为跳过处理的升级包数据为空。异或处理是指按照切片对在不同位数的数据是否相同输出不同结果，即异或处理的处理结果用于指示切片对在不同位数的数据是否相同。比如，当切片对在某个位数的数据相同时，则异或处理结果的相应位数为第一数值，当切片对在某个位数的数据不同时，则异或处理结果在相应位数为第二数值。差分处理是指确定切片对中两个切片的数据差异，即差分处理的结果用于反映每个切片对的数据差异。
本申请实施例中，在制作升级包时，可以先对新旧版本的安装包进行切片，然后根据新旧版本对应的各个切片对的数据相似度，对各个切片对分别进行差分处理、异或处理或跳过处理，比如在数据相同时进行跳过处理，在数据相似度较高时进行异或处理，在数据相似度较低时进行差分处理。而不是对新旧版本对应的所有切片对均进行差分处理。通过根据切片对的数据相似度进行差异性处理，可以克服对所有切片对均进行差分处理存在的缺陷，在较大程度上减小升级包的数据量，生成数据量相对较小的升级包，进一步节省升级包的下载时间，以及降低对终端设备的存储资源的要求。
作为一个示例，多个切片对中包括第一切片对，第一切片对由第一切片序列中的第一切片和所述第二切片序列中的第二切片组成。根据多个切片对中的每个切片对的数据相似度对每个切片对进行数据处理，得到每个切片对对应的升级包数据的操作可以包括如下几种情况：
第一种情况：若第一切片与第二切片的数据相同，则对第一切片对进行跳过处理，第一切片对对应的升级包数据为空。
本申请实施例中，对于数据相同的切片对，可以不对这个切片对进行处理，后续可以直接利用旧版本的切片进行数据安装。
第二种情况：若第一切片与第二切片的数据不同且数据相似度大于或等于第一阈值，即数据高度相似，则对第一切片对进行异或处理，得到第一数据，根据第一数据确定第一切片对对应的升级包数据。
本申请实施例中，对于数据高度相似的切片对，可以对这个切片对进行异或处理，通过异或处理结果指示这个切片对中哪部分数据相同，哪部分数据不同。
作为一个示例，对第一切片对进行异或处理，得到第一数据的操作包括：对第一切片和第二切片中对应字节位置的数据进行异或处理，得到第一数据。
其中，若第一切片和第二切片对应字节位置的数据相同，则第一数据的对应字节位置的数据为第一数值，若第一切片和第二切片对应字节位置的数据不同，则第一数据的对应字节位置的数据为第二数值。也即是，若第一切片和第二切片在相同的某个字节位置的数据相同，则在第一数据的相同字节位置输出第一数值；若第一切片和第二切片在相同的某个字节位置的数据不同，则在第一数据的相同字节位置输出第二数值。
作为一个示例，若第一切片对的数据不是二进制数据，可以先将第一切片对的数据转换为二进制数据，再对转换为二进制数据的第一切片对进行异或处理。例如，对第一切片和第二切片中对应字节位置的数据进行异或处理的操作包括以下两种情况：
若第一切片的数据和第二切片的数据均为二进制数据，则对第一切片和第二切片中对应字节位置的二进制数值进行异或处理，得到第一数据。其中，若第一切片和第二切片对应字节位置的数值相同，则第一数据的对应字节位置的数值为0，若第一切片和第二切片对应字节位置的数值不同，则第一数据的对应字节位置的数值为1。
若第一切片和第二切片中的至少一个切片的数据不是二进制数据，则将第一切片和第二切片中不是二进制数据的切片的数据转换为二进制数据，对转换为二进制数据后的第一切片和第二切片中对应字节位置的二进制数值进行异或处理，得到第一数据。其中，若转换为二进制数据后的第一切片和第二切片对应字节位置的数值相同，则第一数据的对应字节位置的数值为0，若转换为二进制数据后的第一切片和第二切片对应字节位置的数值不同，则第一数据的对应字节位置的数值为1。
作为一个示例，根据第一数据确定第一切片对对应的升级包数据的操作可以包括：将第一数据确定为第一切片对对应的升级包数据。或者，对第一数据进行压缩处理，得到第三数据，将第三数据确定为第一切片对应的升级包数据。
第三种情况：若第一切片与第二切片的数据相似度小于第一阈值，即数据差异较大，则对第一切片对进行差分处理，得到第二数据，根据第二数据确定第一切片对对应的升级包数据。
其中，第二数据为差分处理结果，即第一切片对的差分文件。
本申请实施例中，若第一切片与第二切片的数据差异较大，可以对第一切片对进行差分处理，以通过差分处理结果表示这第一切片对的数据差异。
作为一个示例，根据第二数据确定第一切片对对应的升级包数据可以包括：将第二数据确定为第一切片对对应的升级包数据。或者，对第二数据进行压缩处理，得到第四数据；将第四数据确定为第一切片对对应的升级包数据。
作为一个示例，根据多个切片对中的每个切片对的切片序号、以及每个切片对对应的数据处理类型和升级包数据，生成升级包时，可以将多个切片序号中每个切片序号指示的切片对对应的升级包数据写入初始数据包的数据信息中，将每个切片序号指示的切片对对应的数据处理类型、以及对应的升级包数据在初始数据包的数据信息中的存储位置信息写入所述初始数据包的头信息中，数据写入后的初始数据包为升级包，多个切片序号为所述多个切片对的切片序号。
其中，每个切片序号指示的切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息用于指示每个切片序号指示的切片对对应的升级包数据在初始数据包的数据信息中的存储位置。例如，每个切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息可以每个切片对对应的升级包数据在初始数据包的数据信息中的增量偏移。
如此，生成的升级包的头信息中存储有：多个切片序号中的每个切片序号对应的数据处理类型、以及每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息。升级包的数据信息中存储有每个切片序号对应的升级包数据。
其中，对应数据处理类型为跳过处理的切片序号对应的升级包数据的存储位置信息为空，即对于数据处理类型为跳过处理的切片序号没有对应的升级包数据，也没有对应的升级包数据在升级包中的存储位置信息。每个切片序号对应的升级包数据在升 级包的数据信息中的存储位置信息可以为每个切片序号对应的升级包数据在升级包的数据信息中的增量偏移等。
通过上述方式生成的升级包可以指示旧版本的安装包和新版本的安装包的关联关系，具体可以指示对应的切片序列中哪些切片对数据相同、哪些切片对数据高度相似、哪些切片对数据差异较大，以及数据高度相似的切片对中哪些数据相同、哪些数据不同，以及数据差异较大的切片对的差分文件。如此，对于待进行版本升级的设备来说，该设备获取到该升级包后，也能够根据该升级包和存储的旧版本的安装包还原出新版本的安装包。
此外，还可以将多个切片序号写入初始数据包的头信息中。比如，将多个切片序号、以及每个切片序号对应的数据处理类型和对应的升级包数据在升级包的数据信息中的存储位置信息对应写入初始数据包的头信息中。如此，可以通过切片序号指示对应的数据处理类型和升级包数据。
此外，还可以将切片尺寸写入初始数据包的头部信息中，使得生成的升级包的头信息还包括切片尺寸。进一步地，还可以将切片数量写入初始数据包的头部信息中，使得生成的升级包的头信息还包括切片数量。
通过在头信息中写入切片尺寸和/或切片数量，便于接收到该升级包的终端设备进行还原安装时，根据头信息中的切片尺寸和/或切片数量对终端设备上存储的旧版本的安装包进行切片，得到与升级包中的多个切片序号对应的切片序列。
其中，切片尺寸为第一切片序列和第二切片序列中切片的尺寸。切片数量为第一切片序列和第二切片序列中排序相同的切片对的数量。示例地，第一切片序列和第二切片序列中各个切片的切片尺寸均为预设尺寸，写入头信息的切片尺寸为该预设尺寸。第一切片序列中的切片数量和第二切片序列中的切片数量相同，均为预设数量，写入头信息的切片数量为该预设数量。
通过预先设置切片尺寸和切片数量，可以在制作升级包时，按照预设切片尺寸和预设切片数量对新旧版本的安装包进行切片，保证新旧版本的切片序列的切片尺寸和切片数量对齐，便于后续根据对齐的新旧版本的切片序列中的各个切片对进行处理，生成升级包。另外，通过在头信息中写入预设切片尺寸和预设切片数量，便于接收到该升级包的终端设备进行还原安装时，也按照头信息中的预设切片尺寸和切片数量对终端设备上存储的旧版本的安装包进行切片，得到与升级包中的多个切片序号对应的切片序列，便于后续根据同序号的升级包数据和切片数据还原出新版本的安装包。
第二方面，提供了一种升级包的生成装置，所述升级包的生成装置具有实现上述第一方面中升级包的生成方法行为的功能。所述升级包的生成装置包括至少一个模块，所述至少一个模块用于实现上述第一方面所提供的升级包的生成方法。
第三方面，提供了一种升级包的生成装置，所述升级包的生成装置的结构中包括处理器和存储器，所述存储器用于存储支持升级包的生成装置执行上述第一方面所提供的升级包的生成方法的程序，以及存储用于实现上述第一方面所述的升级包的生成方法所涉及的数据。所述处理器被配置为用于执行所述存储器中存储的程序。所述升级包的生成装置还可以包括通信总线，所述通信总线用于在所述处理器与所述存储器之间建立连接。
第四方面，提供了一种计算机可读存储介质，所述计算机可读存储介质中存储有指令，当其在计算机上运行时，使得计算机执行上述第一方面所述的升级包的生成方法。
第五方面，提供了一种包含指令的计算机程序产品，当其在计算机上运行时，使得计算机执行上述第一方面所述的升级包的生成方法。
第六方面，提供一种升级包的安装方法，应用于第二设备中，所述方法包括：
获取升级包，升级包包括多个切片序号对应的升级包数据以及每个切片序号对应的数据处理类型信息空。根据多个切片序号中的每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理，以得到每个切片序号对应的安装包数据。然后，根据多个切片序号对应的安装包数据，生成新版本的安装包，对新版本的安装包进行安装。
其中，数据处理类型至少包括跳过处理、异或处理或差分处理，对应数据处理类型为跳过处理的升级包数据为空。在数据处理类型不同的情况下，还原处理方式不同。具体地，根据数据处理类型的不同，根据多个切片序号中的每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理包括以下几种情况：
第一种情况：在每个切片序号对应的数据处理类型为跳过处理的情况下，对第一切片序列中与每个切片序号对应的切片进行复制处理，以得到每个切片序列号对应的安装包数据。
其中，第一切片序列是对存储在第二设备上的旧版本的安装包进行切片处理得到。
也即是，若第一切片序号指示的切片对的数据相同，则可以直接将第一切片序列中相应位置的切片数据作为新版本的安装包中相应位置的切片数据。
第二种情况：在每个切片序号对应的数据处理类型为异或处理的情况下，对每个切片序号对应的升级包数据以及第一切片序列中与所述每个切片序号对应的切片进行异或处理，以得到每个切片序列号对应的安装包数据。
第三种情况：在每个切片序号对应的数据处理类型为差分处理的情况下，对每个切片序号对应的升级包数据以及第一切片序列中与每个切片序号对应的切片进行反差分处理，以得到每个切片序列号对应的安装包数据。
其中，反差分处理为差分处理的反向操作，用于根据差分文件还原出原始文件。
本申请实施例中，在对升级包进行安装时，可以根据升级包中各个切片序号对应的数据处理类型，对旧版本的安装包中相同切片序号的切片数据进行还原处理，以还原出新版本的安装包，再对新版本的安装包进行安装。由于升级包的数据量较小，因此对升级包进行还原安装所需要的存储资源也较小，如此降低了对终端设备的存储资源的要求，适应于内存较小的终端设备进行版本更新。
而且，可以根据各个切片序号对应的数据处理类型的不同，对各个切片序号对应的切片进行不同形式的还原处理。比如，在数据处理类型为跳过处理时进行复制处理，在数据处理类型为异或处理时进行异或处理，在数据处理类型为差分处理时进行反差分处理。如此，可以根据数据量较小的升级包，准确还原出新版本的安装包，提出了一种适配于按照上述第一方面所述的升级包的生成方法生成的升级包的还原安装方法。
作为一个示例，升级包的头信息中包括切片尺寸，可以根据该切片尺寸对旧版本 的安装包进行切片，得到第一切片序列。如此，可以使得第一切片序列中的各个切片的尺寸均为该切片尺寸。
作为另一个示例，升级包的头信息中包括切片尺寸和切片数量，可以根据该切片尺寸和切片数量对旧版本的安装包进行切片，得到第一切片序列。如此，可以使得第一切片序列中的各个切片的尺寸均为该切片尺寸，以及第一切片序列包括的切片的数量为该切片数量。
作为一个示例，若升级包的头信息存储有多个切片序号中每个切片序号对应的数据处理类类型和对应的升级包数据在升级包的数据信息中的存储位置信息，升级包的数据信息存储有多个切片序号中每个切片序号对应的升级包数据。则在生成每个切片序号对应的安装包数据之前，可以先从升级包的头信息中获取每个切片序号对应的数据处理类型和对应的升级包数据在升级包的数据信息中的存储位置信息，根据每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息，从升级包的数据信息中获取每个切片序号对应的升级包数据，然后根据每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理。
作为一个示例，可以对多个切片序号对应的安装包数据进行拼接，得到第二安装包。
第七方面，提供了一种升级包的安装装置，所述升级包的安装装置具有实现上述第一方面中升级包的安装方法行为的功能。所述升级包的安装装置包括至少一个模块，所述至少一个模块用于实现上述第一方面所提供的升级包的安装方法。
第八方面，提供了一种升级包的安装装置，所述升级包的安装装置的结构中包括处理器和存储器，所述存储器用于存储支持升级包的安装装置执行上述第一方面所提供的升级包的安装方法的程序，以及存储用于实现上述第一方面所述的升级包的安装方法所涉及的数据。所述处理器被配置为用于执行所述存储器中存储的程序。所述升级包的安装装置还可以包括通信总线，所述通信总线用于在所述处理器与所述存储器之间建立连接。
第九方面，提供了一种计算机可读存储介质，所述计算机可读存储介质中存储有指令，当其在计算机上运行时，使得计算机执行上述第一方面所述的升级包的安装方法。
第十方面，提供了一种包含指令的计算机程序产品，当其在计算机上运行时，使得计算机执行上述第一方面所述的升级包的安装方法。
本申请实施例提供的升级包的生成方法具有如下有益效果：
本申请实施例中，可以先对新旧版本的安装包进行切片，然后根据新旧版本对应的各个切片对的数据相似度，对各个切片对分别进行差分处理、异或处理或跳过处理，比如在数据相同时进行跳过处理，在数据相似度较高时进行异或处理，在数据相似度较低时进行差分处理，得到每个切片对对应的升级包数据。而不是对新旧版本对应的所有切片对均进行差分处理。然后，根据每个切片对对应的数据处理类型和升级包数据，生成升级包。在生成升级包的过程中，通过根据切片对的数据相似度进行差异性处理，可以克服对所有切片对均进行差分处理存在的缺陷，在较大程度上减小升级包 的数据量，生成数据量相对较小的升级包，进一步节省升级包的下载时间，以及降低对终端设备的存储资源的要求。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请的实施方式作进一步地详细描述。
应当理解的是，本申请提及的“多个”是指两个或两个以上。在本申请的描述中，除非另有说明，“/”表示或的意思，比如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，比如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，为了便于清楚描述本申请的技术方案，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
在对本申请实施例提供的生成升级包、安装升级包的方法进行详细说明之前，先对本申请实施例涉及的应用场景和实施环境予以说明。
手机、平板电脑、可穿戴设备等终端设备需要根据供应商发布的升级包，对终端设备的系统或软件等对象进行版本更新。比如，终端设备可以采用空中下载(over the air，OTA)升级技术实现版本更新。OTA技术是一种通过无线网络进行数据下载的技术，OTA升级技术是通过终端设备的无线网络接口实现对终端设备的待升级对象进行远程版本更新的技术，以实现远程升级终端设备的系统或软件等对象的版本。应理解，终端设备也可以采用其他技术实现版本更新。
请参考图1，图1是本申请实施例提供的一种设备进行版本更新的系统示意图。如图1所示，该系统包括第一设备11、第二设备12、第三设备13和第四设备14。第一设备11、第二设备12、第三设备13和第四设备14之间可以通过有限网络或无线网络进行通信。
其中，第一设备11为用于制作和上传升级包的设备，可以为终端设备或服务器等。第二设备12为用于存储和下发升级包的设备，比如云端的服务器。第三设备13为用于下载升级包的设备，可以为终端设备或服务器等。另外，第三设备13在下载升级包后，可以根据该升级包进行版本更新，也可以将下载的升级包转发给第四设备14，由第四设备根据该升级包进行版本更新。第四设备14为用于进行版本升级的设备，可以为终端设备或服务器等。其中，终端设备可以为手机、平板电脑、计算机或可穿戴设备等。
比如，第一设备11制作待升级对象的升级包，将升级包上传至第二设备12，由第二设备12进行存储。第三设备13从第二设备12下载升级包，根据该升级包对待升级对象的版本进行更新。或者，第三设备13也可以在从第二设备12下载升级包之后，将升级包发送给第四设备14，由第四设备14根据该升级包对自身的待升级对象的版本进行更新。
其中，制作升级包的方法主要有两种：一种是采用全量升级方式进行制作，即将新版本的安装包的全部据打包到升级包中，但是这种升级包的数据量较大。另一种是采用差分升级方式进行制作，即对新版本的安装包和旧版本的安装包进行差分处理，得到差分文件，将差分文件打包到升级包中，这种升级包的数据量小于全量升级得到的升级包的数据量。
目前，为了节省服务器的存储资源和终端设备下载升级包的时间，且降低开发成本，升级包通常为采用差分升级方式制作的升级包，即升级包通常为相邻两个版本之间的差分文件。比如，第一设备11可以对旧版本的安装包1和新版本的安装包2整体进行差分处理，得到差分文件，将差分文件打包到升级包中，从而得到待升级对象的升级包。第三设备13或第四设备14获取到该升级包后，可以根据该升级包和旧版本的安装包1进行还原处理，得到新版本的安装包2，通过安装第二安装包实现版本更新。其中，还原处理为差分处理的反向操作，用于根据差分文件还原出原始文件。
但是这种方式得到的升级包的数据量仍然较大，导致下载升级包的设备花费的下载时间较长，且待进行版本更新的设备的存储资源具有一定的要求，需要该设备的存储资源足够大，才能满足升级包的安装需求。比如，对于可穿戴设备等内存较小的设备，由于其内存有限，因此可能无法存储较大数据量的升级包，也无法对较大数据量的升级包进行还原和安装，因此，这种方式得到的升级包无法满足小内存设备的版本更新需求。
为此，相关技术中还提供了另一种制作升级包的方法。请参考图2，图2是相关技术提供的一种升级包的生成和安装过程的逻辑示意图，如图2所示，升级包的生成过程包括：获取旧版本的安装包1和新版本的安装包2。然后，对安装包1进行切片，得到切片序列1，对安装包2进行切片，得到切片序列2。之后，对于切片序列1和切片序列2中排序相同的每个切片对，对每个切片对进行差分处理，得到每个切片对对应的差分文件，然后将差分处理得到的多个切片对对应的差分文件进行拼接，得到升级包。升级包的安装过程包括：获取升级包之后，根据升级包中多个切片对对应的差分文件和旧版本的安装包1进行还原处理，得到新版本的安装包2。
上述制作升级包的方法中，通过先对新旧版本的安装包进行切片，再对新旧版本 对应的所有切片对均进行差分处理，来生成新旧版本的差分文件，虽然可以在一定程度上减小升级包的数据量，但是基于差分算法存在的缺陷，通过这种方式生成的升级包的数据量可能仍然较大。比如，若新旧版本的安装包较小，则切分得到的切片尺寸也较小，对于切片尺寸较小的切片对，对其进行差分处理得到的差分文件反而较大。譬如，对于1个字节大小的切片对，对其进行差分处理得到的差分文件反而大于1个字节。
本申请实施例中，为了较大程度地降低升级包的数据量，节省升级包的下载时间，以及降低对终端设备的存储资源的要求，提供了另一种升级包的生成和安装方法。为了便于理解，接下来将制作升级包的第一设备11为拍包服务器、存储和下发升级包的第二设备12为云端服务器、下载升级包的第三设备13为手机、进行版本更新的第四设备14为耳机为例对设备的版本更新过程进行说明。
图3是本申请实施例提供的另一种设备进行版本更新的系统示意图。如图3所示，该系统包括拍包服务器21、云端服务器22、手机23和耳机24。拍包服务器21、云端服务器22、手机23和耳机24之间可以通过有限网络或无线网络进行连接。其中，耳机24为无线耳机，比如无线蓝牙耳机。拍包服务器21可以获取新版本的安装包1和旧版本的安装包2，根据安装包1和安装包2生成升级包，将升级包上传至云端服务器22。手机23从云端服务器22下载升级包，将该升级包发送给耳机24。耳机24接收该升级包，通过安装该升级包进行版本更新，比如根据旧版本的安装包和升级包，生成新版本的安装包，安装新版本的安装包。
其中，请参考图4，升级包的生成过程可以包括：对安装包1进行切片，得到切片序列1，对安装包2进行切片，得到切片序列2，切片序列1和切片序列2均包括多个切片，切片序列1与切片序列2中排序相同的切片组成一个切片对，切片序列1中的多个切片与切片序列2中的多个切片组成多个切片对。根据多个切片对中的每个切片对的数据相似度对每个切片对进行数据处理，得到每个切片对对应的升级包数据。其中，数据处理包括跳过处理、异或处理或差分处理，通过跳过处理得到的切片对对应的升级包数据为空。然后，根据每个切片对的切片序号、以及每个切片对对应的数据处理类型和升级包数据，生成升级包，该升级包包括多个切片序号对应的升级包数据以及每个切片序号对应的数据处理类型信息，对应数据处理类型为跳过处理的升级包数据为空。
请参考图4，升级包的安装过程包括：根据升级包和安装包1，生成安装包2；对安装包2进行安装。比如，对安装包1进行切片，得到切片序列1。根据升级包包括的多个切片序号中的每个切片序号对应的数据处理类型，对切片序列1中每个切片序号对应的切片进行还原处理，以得到每个切片序号对应的安装包数据；根据多个切片序号对应的安装包数据，生成第二安装包。
也即是，本申请实施例在制作升级包时，在对新旧版本的安装包进行切片之后，可以根据新旧版本对应的各个切片对的数据相似度，对各个切片对分别进行差分处理、异或处理或跳过处理，比如在数据相同时进行跳过处理，在数据相似度较高时进行异或处理，在数据相似度较低时进行差分处理。而不是对新旧版本对应的所有切片对均进行差分处理。通过根据切片对的数据相似度进行差异性处理，可以克服对所有切片 对均进行差分处理存在的缺陷，在较大程度上减小升级包的数据量，生成数据量相对较小的升级包，进一步节省升级包的下载时间，以及降低对终端设备的存储资源的要求。

接下来，对本申请实施例提供的升级包的生成和安装过程进行详细说明。
图7是本申请实施例提供的一种升级包的生成和安装方法的流程图，该方法应用于第一设备和第四设备，如图7所示，该方法包括如下步骤：
步骤701：第一设备获取第一安装包和第二安装包，第二安装包的版本高于第一安装包的版本。
第一安装包和第二安装包为待升级对象的不同版本的安装包，且第二安装包的版本高于第一安装包的版本。待升级对象可以为系统或软件等需要进行版本更新的对象。
比如，第一安装包和第二安装包均为目标软件的安装包，第一安装包为版本1的 安装包，第二安装包为版本2的安装包，版本2高于版本1。目标软件可以为任意软件。
作为一个示例，第一设备可以获取用户上传的第一安装包或第二安装包。或者，根据第一安装包的存储路径获取第一安装包，根据第二安装包的存储路径获取第二安装包。或者，根据第一安装包的下载路径下载第一安装包，根据第二安装包的下载路径获取第二安装包。
在一种可能的实现方式中，第一设备安装有升级包制作软件，相关人员可以在该升级包制作软件的相关界面中上传第一安装包和第二安装包，然后触发升级包制作指令。响应于该升级包制作指令，第一设备的升级包制作软件即可获取用户上传的第一安装包和第二安装包，然后按照下述步骤702-步骤704对第一安装包和第二安装包进行处理，生成升级包。或者，相关人员也可以在升级包制作软件的相关界面中输入或选择第一安装包的存储路径以及第二安装包的存储路径，然后触发升级包制作指令。响应于该升级包制作指令，第一设备的升级包制作软件即可根据第一安装包的存储路径获取第一安装包，根据第二安装包的存储路径获取第二安装包。
应理解，第一设备也可以通过其他方式获取第一安装包和第二安装包，比如从其他设备获取第一安装包和第二安装包，譬如从服务器下载第一安装包和第二安装包，本申请实施例对获取第一安装包和第二安装包的方式不做限定。
步骤702：第一设备对第一安装包进行切片，得到第一切片序列，对第二安装包进行切片，得到第二切片序列，第二切片序列与第一切片序列中排序相同的切片组成一个切片对，第二切片序列中的多个切片与第一切片序列中的多个切片组成多个切片对。
其中，第一切片序列包括多个切片，第二切片序列也包括多个切片。对于第一切片序列和第二切片序列中排序相同的任意两个切片，可以将这两个切片称为切片对。比如，第一切片序列中的第一个切片和第二切片序列中的第一个切片称为一个切片对，第一切片序列中的第二个切片和第二切片序列中的第二个切片称为一个切片对。
作为一个示例，可以按照相同的切片规则对第一安装包和第二安装包进行切片，切片规则包括预设切片尺寸，预设切片尺寸用于指示切片得到的各个切片的尺寸相同，均为该预设切片尺寸。如此，可以保证第一切片序列和第二切片序列中各个切片的尺寸相同。
另外，切片规则还可以包括预设切片数量，用于指示切片得到的切片序列的切片数量为预设切片数量。如此，可以保证第一切片序列和第二切片序列的切片数量相同。
一般而言，不同版本的第一安装包和第二安装包的安装包大小相同或相差不大，因此按照相同的切片规则对第一安装包和第二安装包进行切片后，得到的第一切片序列和第二切片序列的切片数量相同。
例如，假设切片规则中的预设切片尺寸为16k。按照该切片规则对第一安装包进行切片得到的第一切片序列包括4个切片，每个切片的切片尺寸均为16k。按照该切片规则对第二安装包进行切片得到的第二切片序列也包括4个切片，每个切片的切片尺寸均为16k。示例地，切片可以标识为block，简称blk。第一切片序列中的4个切片可以分别标识为：1-blk0，1-blk1，1-blk2，1-blk3，第二切片序列中的4个切片可以 分别标识为：2-blk0，2-blk1，2-blk2，2-blk3。第一切片序列和第二切片序列可以构成4个切片对：1-blk0和2-blk0，1-blk1和2-blk1，1-blk2和2-blk2，以及1-blk3和2-blk3。
步骤703：第一设备根据多个切片对中的每个切片对的数据相似度对每个切片对进行数据处理，得到每个切片对对应的升级包数据，数据处理至少包括跳过处理、异或处理或差分处理。
其中，跳过处理是指不对对应切片对的数据进行处理，通过跳过处理得到的切片对对应的升级包数据为空。异或处理是指采用异或逻辑进行的数据处理，异或逻辑是指当两个数据相同时输出第一数值，当两个数据不同时输出第二数值。比如，对切片对包括的两个切片中对应位数的数据进行异或处理，当切片对在某个位数的数据相同时，则异或处理结果的相应位数为第一数值，当切片对在某个位数的数据不同时，则异或处理结果在相应位数为第二数值。差分处理是指确定切片对中两个切片的数据差异，即差分处理的结果用于反映每个切片对的数据差异。
本申请实施例中，为了减小升级包的数据量，可以根据每个切片对的数据相似度对每个切片对进行差异化处理，而非对每个切片对均进行固化的差分处理。比如，若数据相同则进行跳过处理，若数据高度相似则进行异或处理，若数据差异较大则进行差分处理。如此，可以根据数据相似度，采用较为匹配的数据处理结果来指示每个切片对之间的数据关联性，使得根据数据处理结果生成的升级包的数据量较小。
作为一个示例，多个切片对中包括第一切片对，第一切片对由第一切片序列中的第一切片和第二切片序列中的第二切片组成。根据每个切片对的数据相似度对每个切片对进行数据处理，得到每个切片对对应的升级包数据的操作可以包括如下几种情况：
第一种情况：若第一切片与第二切片的数据相同，则对第一切片对进行跳过处理，第一切片对对应的升级包数据为空。
其中，第一切片对对应的升级包数据为空是指第一切片对没有对应的升级包数据。
对于数据相同的切片对，可以不对这个切片对的数据进行处理，仅需记录这个切片对对应的数据处理类型即可，因此这个切片对对应的升级包数据为空，即这切片对没有对应的升级包数据。
第二种情况：若第一切片与第二切片的数据不同且数据相似度大于或等于第一阈值，则对第一切片对进行异或处理，得到第一数据，根据第一数据确定第一切片对对应的升级包数据。
其中，第一阈值可以预先设置，比如设置为一个较高的相似度阈值。当第一切片与第二切片的数据不同且数据相似度大于第一阈值时，说明第一切片和第二切片的数据高度相似，仅少部分数据不同。例如，第一阈值可以为80％或90％等。
对于数据高度相似的切片对，可以对这个切片对进行异或处理，通过异或处理结果指示这个切片对中哪部分数据相同，哪部分数据不同。
作为一个示例，对第一切片对进行异或处理，得到第一数据的操作包括：对第一切片和第二切片中对应字节位置的数据进行异或处理，得到第一数据。
其中，若第一切片和第二切片对应字节位置的数据相同，则第一数据的对应字节位置的数据为第一数值，若第一切片和第二切片对应字节位置的数据不同，则第一数据的对应字节位置的数据为第二数值。
其中，第一数据为异或处理结果。第一切片、第二切片和第一数据的字节数一般相同。第一数据中的第一数值用于指示第一切片对在对应字节位置的数据相同，第二数值用于指示第一切片对在对应字节位置的数据不同。第一数值和第二数值可以预先设置，比如第一数值为0，第二数值为1。
也即是，若第一切片和第二切片在相同的某个字节位置的数据相同，则在第一数据的相同字节位置输出第一数值；若第一切片和第二切片在相同的某个字节位置的数据不同，则在第一数据的相同字节位置输出第二数值。
通常情况下，异或处理的处理对象一般为二进制数据，若第一切片对的数据不是二进制数据，可以先将第一切片对的数据转换为二进制数据，再对转换为二进制数据的第一切片对进行异或处理。
例如，对第一切片和第二切片中对应字节位置的数据进行异或处理，得到第一数据的操作包括以下两种情况：
1)若第一切片的数据和第二切片的数据均为二进制数据，则对第一切片和第二切片中对应字节位置的二进制数值进行异或处理，得到第一数据。
其中，若第一切片和第二切片对应字节位置的数值相同，则第一数据的对应字节位置的数值为0，若第一切片和第二切片对应字节位置的数值不同，则第一数据的对应字节位置的数值为1。
比如，若第一切片的数据为“1100”，第二切片的数据为“1101”，则对第一切片和第二切片进行异或处理得到的第一数据为“0001”。“0001”中的“0”表示第一切片对在对应字节位置的数据不同，“1”表示第一切片对在对应字节位置的数据不同。
2)若第一切片和第二切片中的至少一个切片的数据不是二进制数据，则将第一切片和第二切片中不是二进制数据的切片的数据转换为二进制数据，对转换为二进制数据后的第一切片和第二切片中对应字节位置的二进制数值进行异或处理，得到第一数据。
其中，若转换为二进制数据后的第一切片和第二切片对应字节位置的数值相同，则第一数据的对应字节位置的数值为0，若转换为二进制数据后的第一切片和第二切片对应字节位置的数值不同，则第一数据的对应字节位置的数值为1。
比如，若第一切片和第二切片的数据为十六进制数据，则可以先将两者对应的十六进制数据转换为二进制数据，再对转换为二进制数据后的第一切片和第二切片进行异或处理。
其中，根据第一数据确定第一切片对对应的升级包数据的操作可以包括以下两种实现方式中的任一种：
第一种实现方式：将第一数据确定为第一切片对对应的升级包数据。
也即是，将异或处理结果直接作为第一切片对对应的升级包数据。比如，若第一数据为“0001”，则将“0001”直接作为第一切片对对应的升级包数据。
第二种实现方式：对第一数据进行压缩处理，得到第三数据，将第三数据确定为第一切片对应的升级包数据。
也即是，先对异或处理结果进行压缩，再将压缩后的异或处理结果作为第一切片对对应的升级包数据。
作为一个示例，在第一数据为二进制数据的情况下，可以对第一数据中的0进行压缩处理，得到第三数据。比如，若第一数据为“0001”，则对第一数据“0001”中的0进行压缩，得到第三数据“1”。如此，可以减小数据量，从而减小数据占用空间和数据传输效率。
其中，对第一数据中的0进行压缩处理后，得到的第三数据包括1，不包括0。此外，第三数据还可以包括被压缩掉的0的字节位置信息或者剩余的1对应的字节位置信息，以指示哪些字节位置的数据被压缩掉，以便后续根据这些信息对压缩后的第三数据进行解压，得到第一数据。
应理解，也可以采用其他压缩方式对第一数据进行压缩处理。
第三种情况：若第一切片与第二切片的数据相似度小于第一阈值，则对第一切片对进行差分处理，得到第二数据，根据第二数据确定第一切片对对应的升级包数据。
若第一切片与第二切片的数据相似度小于第一阈值，说明第一切片和第二切片的数据差异较大，这种情况下，可以对第一切片对进行差分处理，以通过差分处理结果表示这第一切片对的数据差异。
其中，第二数据为差分处理结果，即第一切片对的差分文件。
其中，根据第二数据确定第一切片对对应的升级包数据可以包括以下两种实现方式中的任一种：
第一种实现方式：将第二数据确定为第一切片对对应的升级包数据。
也即是，将差分处理结果直接作为第一切片对对应的升级包数据。
第二种实现方式：对第二数据进行压缩处理，得到第四数据；将第四数据确定为第一切片对对应的升级包数据。
也即是，先对差分处理结果进行压缩，再将压缩后的差分处理结果作为第一切片对对应的升级包数据。对第二数据进行压缩处理的压缩算法可以预先根据需要进行设置，本申请实施例对此不做限定。
通过对第一切片序列和第二切片序列中排序相同的各个切片对进行数据处理，可以得到多个切片对对应的升级包数据。其中，对应数据处理类型为跳过处理的切片对对应的升级包数据为空，即对应数据处理类型为跳过处理的切片对没有对应的升级包数据。
步骤704：第一设备根据多个切片对中每个切片对的切片序号、以及每个切片对对应的数据处理类型和升级包数据，生成升级包，升级包包括多个切片序号对应的升级包数据和以及每个切片序号对应的数据处理类型信息。
其中，数据处理类型信息用于指示对应切片对进行数据处理采用的数据处理类型。数据处理类型包括跳过处理、异或处理或差分处理。
在得到每个切片对对应的升级包数据之后，可以将多个切片序号中每个切片序号指示的切片对对应的数据处理类型和升级包数据打包进升级包，以生成升级包。其中，多个切片序号为多个切片对的切片序号。
作为一个示例，第一切片序列或第二切片序列的切片序号可以用0～n-1表示，n为切片序列的切片数量。应理解，切片序列的切片序号也可以采用其他方式表示，比如用1～n表示，本申请实施例对此不做限定。
作为一个示例，根据每个切片对的切片序号、以及每个切片对对应的数据处理类型和升级包数据，生成升级包的操作包括：将多个切片序号中每个切片序号指示的切片对对应的升级包数据写入初始数据包的数据信息中，将每个切片序号指示的切片对对应的数据处理类型、以及对应的升级包数据在初始数据包的数据信息中的存储位置信息写入所述初始数据包的头信息中，数据写入后的初始数据包为升级包，多个切片序号为所述多个切片对的切片序号。
比如，将每个切片对对应的升级包数据写入初始数据包的数据信息中，将每个切片对的切片序号、每个切片对对应的数据处理类型、以及每个切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息写入初始数据包的头信息中，数据写入后的初始数据包为升级包。其中，对应数据处理类型为跳过处理的切片对对应的升级包数据以及升级包数据对应的存储位置信息均为空。
其中，每个切片序号指示的切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息用于指示每个切片序号指示的切片对对应的升级包数据在初始数据包的数据信息中的存储位置。例如，每个切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息可以每个切片对对应的升级包数据在初始数据包的数据信息中的增量偏移。
如此，生成的升级包的头信息中存储有：多个切片序号中每个切片序号对应的数据处理类型、每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息。升级包的数据信息中存储有每个切片序号对应的升级包数据。其中，对应数据处理类型为跳过处理的切片序号对应的升级包数据的存储位置信息为空，即对于数据处理类型为跳过处理的切片序号没有对应的升级包数据，也没有对应的升级包数据在升级包中的存储位置信息。
此外，还可以将多个切片序号写入初始数据包的头信息中。比如，将多个切片序号、以及每个切片序号对应的数据处理类型和对应的升级包数据在升级包的数据信息中的存储位置信息对应写入初始数据包的头信息中。如此，可以通过切片序号指示对应的数据处理类型和升级包数据。
此外，还可以将切片尺寸写入初始数据包的头部信息中，使得生成的升级包的头信息还包括切片尺寸。进一步地，还可以将切片数量写入初始数据包的头部信息中，使得生成的升级包的头信息还包括切片数量。
通过在头信息中写入切片尺寸和/或切片数量，便于接收到该升级包的终端设备进行还原安装时，根据头信息中的切片尺寸和/或切片数量对终端设备上存储的旧版本的安装包进行切片，得到与升级包中的多个切片序号对应的切片序列。
其中，切片尺寸为第一切片序列和第二切片序列中切片的尺寸。切片数量为第一切片序列和第二切片序列中排序相同的切片对的数量。示例地，第一切片序列和第二切片序列中各个切片的切片尺寸均为预设尺寸，写入头信息的切片尺寸为该预设尺寸。第一切片序列中的切片数量和第二切片序列中的切片数量相同，均为预设数量，写入头信息的切片数量为该预设数量。
通过预先设置切片尺寸和切片数量，可以在制作升级包时，按照预设切片尺寸和预设切片数量对新旧版本的安装包进行切片，保证新旧版本的切片序列的切片尺寸和 切片数量对齐，便于后续根据对齐的新旧版本的切片序列中的各个切片对进行处理，生成升级包。另外，通过在头信息中写入预设切片尺寸和预设切片数量，便于接收到该升级包的终端设备进行还原安装时，也按照头信息中的预设切片尺寸和切片数量对终端设备上存储的旧版本的安装包进行切片，得到与升级包中的多个切片序号对应的切片序列，便于后续根据同序号的升级包数据和切片数据还原出新版本的安装包。
示例地，升级包的头信息可以采用如下格式表示：
其中，block_size为切片尺寸，block_num为切片数量，operate_type为数据处理类型，blk_no和offset分别为该数据处理类型对应的切片序号和对应的升级包数据在升级包中的增量偏移。
其中，不同的数据处理类型可以采用不同的数据处理类型标识来表示。比如，可以采用如下数据处理类型标识来标识不同的数据处理类型：
假设第一切片序列包括4个切片：1-blk0，1-blk1，1-blk2，1-blk3；第二切片序列也包括4个切片：2-blk0，2-blk1，2-blk2，2-blk3。各个切片的切片尺寸均为16k。切片序号为0的第一个切片对“1-blk0和2-blk0”对应的数据处理类型为跳过处理，跳过处理的数据处理类型标识为0。切片序号为1的第二个切片对“1-blk1和2-blk1”以及切片序号为3的第四个切片对“1-blk3和2-blk3”对应的数据处理类型为异或处理，异或处理处理的数据处理类型标识为1，第二个切片对和第四个切片对对应的升级包数据在升级包中的增量偏移分别为10和8。切片序号为2的第三个切片对“1-blk2和2-blk2”对应的数据处理类型为差分处理，差分处理的数据处理类型标识为2，第三个切片对对应的升级包数据在升级包中的增量偏移为5。则升级包的头信息可以为：
另外，若按照相同的切片规则对第一安装包和第二安装包进行切片后得到两个切片序列的切片数量不同，还可以在切片数量较少的切片序列的序列末尾补充特定数量的空白切片，从而得到切片数量相同的第一切片序列和第二切片序列。
对于通过补充空白切片后得到的切片数量相同的第一切片序列和第二切片序列来说，第一切片序列和第二切片序列中排序相同的各个切片对中，有些切片对中的两个切片均存储有数据，为了便于说明，将这种切片对称为第一类切片对。而有些切片对中只有一个切片存储有数据、另一个切片的数据为空，为了便于说明，将这种切片对称为第二类切片对。第二类切片对的数据相似度非常小。
本申请实施例中，还可以根据每个切片对的数据相似度和所属的切片对类别，对每个切片对进行数据处理，得到每个切片对对应的升级包数据。数据处理除了可以包括跳过处理、异或处理或差分处理之外，还可以包括复制处理或删除处理。切片对类别包括第一类切片对或第二类切片对。
其中，复制处理是指对对应切片对中属于第二切片序列的切片进行复制，得到该切片对对应的升级包数据。删除处理也是指不对对应切片对的数据进行处理，通过删除处理得到的切片对对应的升级包数据也为空。
比如，对于第一切片序列和第二切片序列中排序相同的第一切片对，若第一切片对的数据相同且第一切片对属于第一类切片对，则对第一切片对进行跳过处理，第一切片对对应的升级包数据为空。若第一切片对的数据不同、数据相似度大于或等于第一阈值且第一切片对属于第一类切片对，则对第一切片对进行异或处理，得到第一数据，根据第一数据确定第一切片对对应的升级包数据。若第一切片对对应的数据相似对小于第一阈值且第一切片对属于第一类切片对，则对第一切片对进行差分处理，得到第二数据，根据第二数据确定第一切片对对应的升级包数据。
此外，若第一切片对对应的数据相似对小于第一阈值、第一切片对属于第二切片对且第一切片对中的空白切片属于第一切片序列，说明第二安装包相对于第一安装包新增了部分数据，则可以对第一切片对进行复制处理，即对第一切片对中属于第二切片序列的切片进行复制，得到第一切片对对对应的升级包数据。
若第一切片对对应的数据相似对小于第一阈值、第一切片对属于第二切片对且第一切片对中的空白切片属于第二切片序列，说明第二安装包相对于第一安装包删除了部分数据，则可以对第一切片对进行删除处理，第一切片对对应的升级包数据为空。
如此，生成的升级包包括多个切片序号中的每个切片序号对应的数据处理类型和升级包数据，每个切片序号对应的数据处理类型为跳过处理、异或处理、差分处理、复制处理或删除处理，对应数据处理类型为跳过处理和删除处理的升级包数据为空，即对应数据处理类型为跳过处理和删除处理的切片序号没有对应的升级包数据。相应地，若升级包的头信息中包括每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息，则对应数据处理类型为跳过处理和删除处理的切片序号对应的存储位置信息为空，即对应数据处理类型为跳过处理和删除处理的切片序号没有对应的存储位置信息。
需要说明的是，生成的升级包可以指示第一安装包和第二安装包的关联关系，具体可以指示对应的切片序列中哪些切片对数据相同、哪些切片对数据高度相似、哪些切片对数据差异较大，以及数据高度相似的切片对中哪些数据相同、哪些数据不同，以及数据差异较大的切片对的差分文件。
步骤705：第一设备向第四设备发送升级包。
第一设备可以直接将第一设备发送给第四设备，也可以通过其他设备向第四设备转发升级包，本申请实施例对此不做限定。比如，请参考上述图1，第一设备可以先将升级包上传至第二设备，再由第三设备从第二设备下载升级包，将下载的升级包转发给第四设备。或者，也可以由第四设备从第二设备下载升级包。
另外，第一设备可以先对升级包进行压缩，得到升级包的压缩包，再向第四设备发送升级包的压缩包。比如，请参考上述图1，第一设备可以对升级包进行压缩，将升级包的压缩包上传至第二设备，再由第三设备从第二设备下载升级包的压缩包，将下载的升级包的压缩包转发给第四设备。或者，第三设备从第二设备下载升级包的压缩包后，也可以先对压缩包进行解压得到升级包，再将解压得到的升级包发送给第四设备。或者，也可以由第四设备从第二设备下载升级包的压缩包。
步骤706：第四设备接收来自第一设备的升级包。
作为一个示例，第四设备可以接收升级包的压缩包，对压缩包进行解压，得到升级包。应理解，第四设备也可以通过其他方式获取升级包，本申请实施例对此不做限定。
步骤707：第四设备根据该升级包和存储的第一安装包，生成第二安装包。
由于升级包是根据第一安装包和第二安装包生成得到，可以指示第一安装包和第二安装包之间的关联关系，因此第四设备获取升级包后，可以根据该升级包和存储的第一安装包还原出第二安装包。
作为一个示例，根据升级包和存储的第一安装包，生成第二安装包的操作可以包括如下步骤：
1)根据多个切片序号中的每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理，以得到每个切片序号对应的安装包数据。
其中，每个切片序号对应的数据处理类型至少包括跳过处理、异或处理或差分处理。在数据处理类型不同的情况下，还原处理方式不同。
具体地，根据数据处理类型的不同，根据多个切片序号中的每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理可以包括以下几种情况：
第一种情况：在每个切片序号对应的数据处理类型为跳过处理的情况下，对第一切片序列中与每个切片序号对应的切片进行复制处理，以得到每个切片序列号对应的安装包数据。
其中，第一切片序列是对存储在第二设备上的旧版本的安装包进行切片处理得到。
也即是，若第一切片序号指示的切片对的数据相同，则可以直接将第一切片序列中相应位置的切片数据作为新版本的安装包中相应位置的切片数据。比如，切片序号0对应的数据处理类型为跳过处理，则将第一切片序列中切片序号0对应切片的数据作为切片序号0对应的安装包数据。
第二种情况：在每个切片序号对应的数据处理类型为异或处理的情况下，对每个切片序号对应的升级包数据以及第一切片序列中与所述每个切片序号对应的切片进行异或处理，以得到每个切片序列号对应的安装包数据。
其中，具体异或处理方式可以参考上述实施例中的相关描述，本申请实施例在此不再赘述。比如，若切片序号1对应的数据处理类型为异或处理，且切片序号1对应 的升级包数据为“0001”，第一切片序列中切片序号1对应切片的数据为“1100”，则对“0001”和“1100”进行异或处理，得到切片序号1对应的安装包数据为“1101”。
第三种情况：在每个切片序号对应的数据处理类型为差分处理的情况下，对每个切片序号对应的升级包数据以及第一切片序列中与每个切片序号对应的切片进行反差分处理，以得到每个切片序列号对应的安装包数据。
其中，反差分处理为差分处理的反向操作，用于根据差分文件还原出原始文件。
比如，若切片序号2对应的数据处理类型为差分处理，则对切片序号2对应的升级包数据和第一切片序列中切片序号2对应切片的数据进行还原处理，得到切片序号2对应的安装包数据。
作为一个示例，若升级包的头信息存储有多个切片序号中每个切片序号对应的数据处理类型和对应的升级包数据在升级包的数据信息中的存储位置信息，升级包的数据信息存储有多个切片序号中每个切片序号对应的升级包数据。则在得到每个切片序号对应的安装包数据之前，可以先从升级包的头信息中获取多个切片序号中每个切片序号对应的数据处理类型和对应的升级包数据在升级包的数据信息中的存储位置信息，根据每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息，从升级包的数据信息中获取每个切片序号对应的升级包数据，然后根据每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理，以得到每个切片序号对应的安装包数据。
此外，若升级包中每个切片序号对应的数据处理类型还可以包括复制处理或删除处理，则根据多个切片序号中的每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理的操作还包括如下第四种情况和第五种情况：
第四种情况：在每个切片序号对应的数据处理类型为复制处理的情况下，对第一切片序号对应的升级包数据进行复制，得到第一切片序号对应的安装包数据，以实现在第二安装包中插入第一安装包中新增的第一切片序号对应的升级包数据。
第五种情况：在每个切片序号对应的数据处理类型为删除处理的情况下，对每个切片序号对应的升级包数据以及第一切片序列中与所述每个切片序号对应的切片进行异或处理进行跳过处理，得到的第一切片序号对应的升级包数据为空，以实现将第一安装包中对应切片序号的切片数据删除。
另外，生成第二安装包之前，还可以先对存储的第一安装包进行切片，得到第一切片序列。作为一个示例，升级包的头信息中包括切片尺寸，可以根据该切片尺寸对第一安装包进行切片，使得第一切片序列中的各个切片的尺寸均为该切片尺寸。作为另一个示例，升级包的头信息中包括切片尺寸和切片数量，可以根据该切片尺寸和切片数量对第一安装包进行切片，使得第一切片序列中的各个切片的尺寸均为该切片尺寸，以及第一切片序列包括的切片的数量为该切片数量。
2)根据多个切片序号对应的安装包数据，生成第二安装包。
比如，可以对多个切片序号对应的安装包数据进行拼接，得到第二安装包。
步骤708：第四设备对第二安装包进行安装。
通过对第二安装包进行安装，即可实现版本更新。
本申请实施例中，在制作升级包时，可以先对新旧版本的安装包进行切片，然后 根据新旧版本对应的各个切片对的数据相似度，对各个切片对分别进行差分处理、异或处理或跳过处理，比如在数据相同时进行跳过处理，在数据相似度较高时进行异或处理，在数据相似度较低时进行差分处理。而不是对新旧版本对应的所有切片对均进行差分处理。通过根据切片对的数据相似度进行差异性处理，可以克服对所有切片对均进行差分处理存在的缺陷，在较大程度上减小升级包的数据量，生成数据量相对较小的升级包，进一步节省升级包的下载时间，以及降低对终端设备的存储资源的要求。
另外，在对升级包进行安装时，可以根据升级包中各个切片序号对应的数据处理类型，对各个切片序号对应的切片进行还原处理，还原出新版本的安装包，再对新版本的安装包进行安装。由于升级包的数据量较小，因此对升级包进行还原安装所需要的存储资源也较小，如此降低了对终端设备的存储资源的要求，适应于内存较小的终端设备进行版本更新。而且，可以根据各个切片序号对应的数据处理类型的不同，对各个切片序号对应的切片进行不同形式的还原处理。比如，在数据处理类型为跳过处理时进行复制处理，在数据处理类型为异或处理时进行异或处理，在数据处理类型为差分处理时进行反差分处理。如此，可以根据数据量较小的升级包，准确还原出新版本的安装包，提出了一种适配于数据量较小的升级包的还原安装方法。
接下来，结合上述图3，以制作升级包的设备为拍包服务器21、存储和下发升级包的设备为云端服务器22、下载升级包的设备为手机23、进行版本更新的设备为耳机24为例，对本申请实施例提供的升级包的生成和安装方法进行详细说明。
图8是本申请实施例提供的一种设备进行版本更新的流程示意图，如图8所示，该方法包括如下步骤：
步骤801：拍包服务器21获取旧版本的安装包1和新版本的安装包2。
安装包1和安装包2为待升级对象的不同版本的安装包，且安装包2的版本高于安装包1的版本。待升级对象可以为系统或软件等需要进行版本更新的对象。
步骤802：拍包服务器21对安装包1进行切片，得到切片序列1，对安装包2进行切片，得到切片序列2，切片序列1和切片序列2中排序相同的切片组成多个切片对。
请参考图9，图9是本申请实施例提供的一种升级包的生成和安装过程的示意图。如图9所示，在升级包的生成过程中，可以按照相同的切片规则对安装包1和安装包2进行切片，切片规则包括切片尺寸＝16k，用于指示切片得到的每个切片的切片尺寸均为16k。另外，对安装包1进行切片得到的切片序列1包括4个切片：1-blk0，1-blk1，1-blk2，1-blk3。对安装包2进行切片得到的切片序列2也包括4个切片：2-blk0，2-blk1，2-blk2，2-blk3。
步骤803：拍包服务器21根据多个切片对中的每个切片对的数据相似度对每个切片对进行数据处理，得到每个切片对对应的升级包数据，数据处理至少包括跳过处理、异或处理或差分处理。
其中，跳过处理是指不对对应切片对的数据进行处理，通过跳过处理得到的切片对对应的升级包数据为空。
其中，若数据相同则进行跳过处理，若数据不同且数据相似度大于或等于第一阈 值，则进行异或处理，若数据相似度小于第一阈值，则进行差分处理。
请参考图9，切片序号0对应的切片对“1-blk0和2-blk0”的数据相同，则对“1-blk0和2-blk0”进行跳过处理，切片序号0对应的升级包数据为空，即切片序号0没有对应的升级包数据。切片序号1对应的切片对“1-blk1和2-blk1”的数据相似度大于第一阈值即数据高度相似，则对“1-blk1和2-blk1”进行异或处理，得到数据p1，对数据p1进行压缩，得到切片序号1对应的升级包数据p1’。切片序号2对应的切片对“1-blk2和2-blk2”的数据相似度小于第一阈值即数据差异较大，则对“1-blk2和2-blk2”进行差分处理，得到切片序号2对应的升级包数据p2。切片序号3对应的切片对“1-blk3和2-blk3”的数据相似度大于第一阈值即数据高度相似，则对“1-blk3和2-blk3”进行异或处理，得到数据p3，对数据p3进行压缩，得到切片序号3对应的升级包数据p3’。
步骤804：拍包服务器21将每个切片对对应的升级包数据写入初始数据包的数据信息中，将切片数量、切片尺寸、每个切片对的切片序号、每个切片对对应的数据处理类型、以及每个切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息写入初始数据包的头信息中，数据写入后的初始数据包为升级包。
其中，每个切片对对应的升级包数据在初始数据包的数据信息中的存储位置信息可以为每个切片对对应的升级包数据在初始数据包的数据信息中的增量偏移等。
请参考图9，可以将切片序号1对应的升级包数据p1’、切片序号2对应的升级包数据p2和切片序号3对应的升级包数据p3’写入升级包的数据信息中。p1’、p2和p3’在升级包的数据信息中的增量偏移分别为10，5和8。另外，还可以将切片数量、切片尺寸、切片序号0对应的数据处理类型、切片序列1～3对应的数据处理类型和升级包数据的增量偏移写入升级包的头信息中。
比如，升级包的头信息包括如下内容：
步骤805：拍包服务器21对升级包进行压缩，得到升级包的压缩包。
步骤806：拍包服务器21向云端服务器22发送升级包的压缩包。
也即是，拍包服务器21可以将升级包的压缩包上传至云端服务器22。
应理解，拍包服务器21也可以不对升级包进行压缩，直接向云端服务器22发送升级包。
步骤807：云端服务器22向手机23发送升级包的压缩包。
其中，云端服务器22可以主动向手机23推送升级包的压缩包，也可以根据手机23的下载请求向手机23发送升级包的压缩包，本申请实施例对此不做限定。
比如，手机23可以向云端服务器22发送待升级对象的版本更新请求，云端服务器22根据版本更新请求向云端服务器22发送该升级包的压缩包。
步骤808：手机23对升级包的压缩包进行解压，得到升级包。
步骤809：手机23向耳机24发送升级包。
其中，耳机24为预先与手机23进行绑定的设备。手机23与耳机24通过无线局域网络进行连接，比如通过蓝牙进行连接。对于耳机24中的系统或软件等待升级对象，可以由手机3从云端服务器22下载待升级对象的升级包或升级包的压缩包，再由手机23通过无线局域网络发送给耳机24。
应理解，手机23接收到云端服务器22发送的升级包的压缩包后，也可以不对压缩包进行压缩，而是直接将压缩包发送给耳机24。或者，手机23也可以接收到云端服务器22发送的升级包，将升级包发送给耳机24。
步骤810：耳机24接收该升级包，从升级包的头信息中获取切片数量、切片尺寸、多个切片序号、以及每个切片序号对应的数据处理类型、每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息。
步骤811：耳机24根据切片尺寸和切片数量，对旧版本的安装包1进行切片，得到切片序列1。
请参考图9，在升级包的安装过程中，对安装包1进行切片得到的切片序列1包括4个切片：1-blk0，1-blk1，1-blk2，1-blk3。
应理解，耳机24也可以通过其他方式获取安装包1对应的切片序列1，比如获取已存储的切片序列1，或者从其他设备获取切片序列1，本申请实施例对此不做限定。
步骤812：耳机24根据多个切片序号及每个切片序号对应的升级包数据在升级包的数据信息中的存储位置信息，从升级包的数据信息中获取多个切片序号中每个切片序号对应的升级包数据。
获取到每个切片序号对应的升级包数据之后，若某个切片序号对应的升级包数据为压缩数据，还可以对获取的升级包数据进行解压，然后根据解压后的升级包数据执行下述步骤813。
比如，请参考图9，可以从升级包的数据信息中获取到切片序号1对应的升级包数据p1’、切片序号2对应的升级包数据p2和切片序号3对应的升级包数据p3’。然后，对切片序号1对应的升级包数据p1’进行解压，得到数据p1，对切片序号3对应的升级包数据p3’进行解压，得到p2。
步骤813：耳机24根据多个切片序号中的每个切片序号对应的数据处理类型，对每个切片序号对应的切片进行还原处理，以得到每个切片序号对应的安装包数据。
比如，若某个切片序号对应的数据处理类型为跳过处理，则对切片序列1中切片序号相同的切片进行复制处理，以得到该切片序列号对应的安装包数据。若某个切片序号对应的数据处理类型为异或处理，则对该切片序号对应的升级包数据以及切片序列1中相同每个切片序号对应的切片进行异或处理，以得到该切片序列号对应的安装包数据。若某个切片序号对应的数据处理类型为差分处理，则对该每个切片序号对应的升级包数据以及切片序列1中相同切片序号对应的切片进行反差分处理，以得到该每个切片序列号对应的安装包数据。
请参考图9，切片序号0～3对应的数据处理类型分别为跳过处理、异或处理、差分处理和异或处理。对切片序列1中切片序号0的切片进行复制处理，得到切片序号0对应的安装包数据，即2-blk0。对切片序号1对应的解压后的升级包数据p1和切片 序列1中的1-blk1的数据进行异或处理，得到切片序号1对应的安装包数据，即2-blk1。对切片序号2对应的升级包数据p2和切片序列1中的1-blk2中的数据进行反差分处理，得到切片序号2对应的安装包数据，即2-blk2。对切片序号3对应的解压后的升级包数据p3和切片序列3中的1-blk3的数据进行异或处理，得到切片序号3对应的安装包数据，即2-blk4。
步骤814：耳机24对多个切片序号对应的安装包数据进行拼接，得到新版本的安装包2。
请参考图9，将2-blk0、2-blk1、2-blk2和2-blk3进行拼接，得到安装包2。
步骤815：耳机24对安装包2进行安装。
通过对第二安装包进行安装，即可实现版本更新。
本申请实施例中，在制作升级包时，可以先对新旧版本的安装包进行切片，然后根据新旧版本对应的各个切片对的数据相似度，对各个切片对分别进行差分处理、异或处理或跳过处理，比如在数据相同时进行跳过处理，在数据相似度较高时进行异或处理，在数据相似度较低时进行差分处理。而不是对新旧版本对应的所有切片对均进行差分处理。通过根据切片对的数据相似度进行差异性处理，可以克服对所有切片对均进行差分处理存在的缺陷，在较大程度上减小升级包的数据量，生成数据量相对较小的升级包，进一步节省升级包的下载时间，以及降低对终端设备的存储资源的要求。
另外，在对升级包进行安装时，可以根据升级包中各个切片序号对应的数据处理类型，对各个切片序号对应的切片进行还原处理，还原出新版本的安装包，再对新版本的安装包进行安装。由于升级包的数据量较小，因此对升级包进行还原安装所需要的存储资源也较小，如此降低了对终端设备的存储资源的要求，适应于内存较小的终端设备进行版本更新。而且，可以根据各个切片序号对应的数据处理类型的不同，对各个切片序号对应的切片进行不同形式的还原处理。比如，在数据处理类型为跳过处理时进行复制处理，在数据处理类型为异或处理时进行异或处理，在数据处理类型为差分处理时进行反差分处理。如此，可以根据数据量较小的升级包，准确还原出新版本的安装包，提出了一种适配于数据量较小的升级包的还原安装方法。

图11是本申请实施例提供的一种升级包的安装装置的结构示意图，该装置可以由软件、硬件或者两者的结合实现成为计算机设备的部分或者全部，该计算机设备可以为图1所示的第三设备13或第四设备14，或者图3所示的手机23或耳机24。参见图11，该装置包括：获取模块1101、生成模块1102和安装模块1103。
