在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本申请的说明，其本身没有特有的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
下文中将结合附图对本申请的实施例进行说明。
在一个示例性实施方式中，图1为本申请实施例提供的一种程序控制方法的流程示意图。该方法适用于动态地控制程序的情况。该方法可以由本申请提供的程序控制装置执行，该程序控制装置可以由软件和/或硬件实现，并集成在计算机设备中。
如图1所示，本申请实施例提供的程序控制方法，包括：
S110、获取待处理程序在编译时期生成的调试信息；所述调试信息通过预置在所述待处理程序中的插桩函数获取。
待处理程序可以是需要被动态控制的程序，示例性的，C语言程序或C++语音程序等，本申请实施例并不对待处理程序所应用的编程语言的类型进行限定。调试信息可以是待处理程序在编译时所生成的相关信息，具有一定的数据格式，其数据格式的类型取决于采用的编程语言的类型。例如，如果待处理程序的编程语言采用C语言，则调试信息诸如可以是函数调用时的指针信息或入 参信息等，本申请实施例并不对调试信息的类型进行限定。
在本申请实施例中，可以由与待处理程序相连的计算机设备对待处理程序进行动态控制。在待处理程序运行之前，可以预先在待处理程序中预置插桩函数。插桩函数的数量可以是一个或多个，可以根据实际需求设定，本申请实施例并不对插桩函数的数量进行限定。相应的，在待处理程序编译运行时，可以由内置在待处理程序中的插桩函数获取待处理程序所生成的调试信息，并将获取的调试信息发送至与待处理程序相连的计算机设备。
S120、解析所述调试信息，得到调试信息解析结果。
调试信息解析结果可以是对调试信息进行解析所得到的解析结果。
在计算机设备获取到待处理程序生成的调试信息后，即可对调试信息进行解析，得到匹配的调试信息解析结果。调试信息解析结果可以反应待处理程序在编译运行时所涉及的参数信息。例如，如果待处理程序的编程语言采用C语言，则调试信息解析结果诸如可以是函数调用的栈信息或入参数值等。也即，调试信息可以是待处理程序的行为数据，而调试信息解析结果则可以是对行为数据的语义分析。
由于调试信息具有一定的数据格式，待处理程序所采用的编程语言的类型不同时，调试信息对应的数据格式可能不同。因此，需要根据调试信息的数据格式对调试信息进行解析，以避免解析失败。
示例性的，假设调试信息的数据格式为：字节1：Ab，字节2：Ac，字节3：D，则对该调试信息的调试信息解析结果可以是：字节1的数据加字节3的数据得到参数E，也即，E＝AbD。
S130、根据所述调试信息解析结果对所述待处理程序进行控制。
在计算机设备获取到调试信息对应的调试信息解析结果后，即可根据调试信息解析结果对待处理程序进行控制。所谓控制诸如可以是监控待处理程序内部的运行状态、改变待处理程序输出的信息或改变待处理程序的运行行为等，本申请实施例并不对待处理程序的控制行为类型进行限定。根据调试信息解析结果对待处理程序进行控制，可以是动态控制运行状态中的待处理程序。
在上述方案中，通过预置在待处理程序中的插桩函数获取待处理程序在编译时期生成的调试信息，并根据调试信息的调试信息解析结果对运行状态中的待处理程序进行动态地控制。也即，本申请实施例所提供的程序控制方法无需中断待处理程序的运行状态，因此也无需重新编译待处理程序的软件版本并重新替换新的待处理程序，更无需重启设备或待处理程序，在待处理程序运行过程中即可对其进行动态的控制，以解决待处理程序的故障问题，或更改待处理 程序的行为需求等。由此可见，在程序运行过程中对程序进行动态控制，可以大幅缩减程序修改、重新编译、替换旧版本以及重新操作所消耗的时间，从而提高程序的控制效率。
本申请实施例通过预置在待处理程序中的插桩函数获取待处理程序在编译时期生成的调试信息，以对获取的调试信息进行解析得到调试信息解析结果，进而根据调试信息解析结果对待处理程序进行控制，解决需要通过重新编译、发布及替换等编辑操作对程序进行控制时存在的效率低的问题，实现在不重新编译软件版本、不重新替换软件、不重启设备或者重启程序的前提下，动态地控制程序，从而提高程序的控制效率。
在一个示例性实施方式中，图2为本申请实施例提供的另一种程序控制方法的流程示意图。本实施例以上述实施例为基础进行说明，在本实施例中，给出了根据所述调试信息解析结果对所述待处理程序进行控制的多种可选的实现方式。如图2所示，本实施例的方法可以包括：
S210、在与所述待处理程序建立连接的情况下，通过所述插桩函数捕获所述待处理程序中的函数调用行为，以获取所述待处理程序在编译时期生成的调试信息。
对待处理程序进行动态控制的计算机设备需要与待处理程序建立连接，才可以对待处理程序进行控制。相应的，如果计算机设备没有与待处理程序建立连接，此时插桩函数可以不做任何动作，也即不进行函数调用行为的捕获操作。在计算机设备与待处理程序建立连接后，插桩函数才开始执行捕获操作，并对待处理程序中的函数调用行为进行捕获，以获取待处理程序在编译时期生成的调试信息。
在本申请的一个可选实施例中，所述调试信息可以包括所述插桩函数捕获函数调用行为时获取的当前指针变量、堆栈指针、入参类型、入参堆栈位置以及入参结构体中的至少一项。
可选的，调试信息可以包括但不限于插桩函数捕获函数调用行为时获取的当前指针变量堆栈指针、入参类型、入参堆栈位置以及入参结构体。其中，当前指针变量可以用于确定插桩函数捕获的函数类型，并可以用于确定待处理程序的调用函数的调用链。堆栈指针可以用于确定待处理程序的堆栈信息。入参类型、入参堆栈位置以及入参结构体可以用于确定入参信息，如入参类型或入参数值等。
S220、解析所述调试信息，得到调试信息解析结果。
在本申请的一个可选实施例中，所述调试信息解析结果可以包括所述待处理程序中函数调用行为所调用的调用栈关联信息、入参类型以及入参数值中的至少一项；其中，所述调用栈关联信息可以包括调用链和/或堆栈信息。
可选的，调试信息解析结果可以包括但不限于待处理程序中函数调用行为所调用的调用栈关联信息、入参类型以及入参数值。其中，调用栈关联信息可以包括调用链和/或堆栈信息，可以通过对当前指针变量及堆栈指针进行解析获取，入参类型可以根据调试信息中的入参类型进行解析获取，入参数值则可以根据入参堆栈位置以及入参结构体进行解析获取。
S230、根据所述调试信息解析结果执行与所述插桩函数存在映射关系的动态指令，以对所述待处理程序进行控制。
所述动态指令包括动态命令和/或动态脚本。
动态指令可以用于对待处理程序进行动态控制，如修改调用函数的行为。动态指令可以包括但不限于动态命令和/或动态脚本。动态命令可以是程序中常用的命令，如延时、打印参数、参数保存、返回等命令。动态脚本可以是指用高级语言编写的解释性质的脚本，动态脚本可以动态的修改，不需要编译、打包及发布等操作。
可选的，计算机设备可以根据获取的调试信息解析结果执行与插桩函数存在映射关系的动态命令和/或动态脚本等动态指令，对待处理程序进行动态控制。插桩函数可以对应设置一个或多个动态命令和/或动态脚本，也即，插桩函数可以与一个或多个动态命令和/或动态脚本建立映射关系，本申请实施例并不对插桩函数所对应设置的动态命令和/或动态脚本的数量进行限定。
图3是本申请实施例提供的一种程序控制的示意图。在一个可选的示例中，如图3所示，以嵌入式C语言程序作为待处理程序，并利用行为捕获套件对运行时C程序进行动态控制。其中，行为捕获套件可以运行在与待处理程序相连的计算机设备中。可选的，可以在C程序代码中预置多个插桩函数(图3中预置了3个插桩函数)。当运行时C程序未与行为捕获套件建立连接时，插桩函数不做任何动作。当行为捕获套件通过网线或串口等形式连接到运行时C程序后，插桩函数可以开始捕获C程序中的函数调用行为，以获取运行时c程序在编译时期生成的当前网际互连协议(Internet Protocol，IP)指针、堆栈指针、入参类型、入参堆栈位置以及入参结构体等调试信息，并将获取的调试信息发送至行为捕获套件。
行为捕获套件内部包括远端动态解析程序，可以接收插桩函数发送的调试信息。远端动态解析程序可以解析调试信息，对运行时C程序的栈结构进行分 析，从而获取当前调用函数调用的调用链、堆栈信息、调用函数的入参类型及入参数值等调试信息解析结果，也即获取对栈结果的分析结果。相应的，远端动态解析程序可以根据栈结果的分析结果，执行插桩函数对应设置的动态命令和/或动态脚本，以对运行时C程序执行监控程序内部的运行状态、改变程序的输出打印信息或改变程序的运行行为等动态控制操作。
如图3所示，行为捕获套件内部还可以包括行为记录数据库和行为展示模块。其中，行为记录数据库可以用于记录函数调用行为的时间、参数信息、调用链或堆栈信息等，行为记录数据库还可以提供数据的查询、分析或过滤等机制，对存储的数据进行数据处理。行为展示模块可以提供可视化展示功能，以展示程序控制过程中所采集到的行为信息，也即行为记录数据库存储的数据。
S230可以包括：
S231a、遍历所述调试信息解析结果，查找待控制入参参数。
S232a、根据预先配置的动态脚本将所述待控制入参参数的当前参数值修改为目标参数值。
待控制入参参数可以是待处理程序中需要被动态控制的入参参数。当前参数值可以是待控制入参参数当前所使用的参数值，目标参数值可以是针对待处理程序控制需求所设定的参数值。
可选的，在计算机设备对待处理程序进行动态控制时，如果需要对程序故障或硬件故障(如硬件损坏等)等情况进行处理，可以遍历调试信息解析结果，查找待控制入参参数，并利用捕获该调试信息的插桩函数预先配置的动态脚本，将待控制入参参数的当前参数值修改为目标参数值。
在一个可选的示例中，结合图3举例说明。假设将C程序作为待处理程序，则在C程序运行之前，预置一个或多个插桩函数。如果C程序中目标函数的目标入参取值为100时会引发程序故障，需要在检测到目标入参取值100时，将目标入参的参数值修改为200。为此，可以在行为捕获套件中配置动态脚本，该动态脚本的功能是：检测到目标函数的目标入参的参数值为100时，将目标入参的参数值修改为200。相应的，如果运行时C程序的目标函数调用时被插桩函数捕获，则行为捕获套件可以遍历调试信息解析结果，查找目标入参，并将目标入参的当前参数值100修改为200，从而有效规避程序故障问题。
S231b、遍历所述调试信息解析结果，查找待控制入参参数。
S232b、根据预先配置的动态命令对所述待控制入参参数执行数据输出操作。
所述数据输出操作包括打印所述待控制入参参数的当前参数值，和/或，存储所述待控制入参参数的当前参数值。
可选的，在计算机设备对待处理程序进行动态控制时，如果需要对程序中的函数入参进行分析，则可以遍历调试信息解析结果，查找待控制入参参数，并利用捕获该调试信息的插桩函数预先配置的动态命令，对待控制入参参数执行打印参数值或存储参数值等数据输出操作。
在一个可选的示例中，结合图3举例说明。假设将C程序作为待处理程序，则在C程序运行之前，预置一个或多个插桩函数。如果有对C程序中目标函数的目标入参进行打印和分析的需求，则可以在行为捕获套件中配置动态命令，该动态命令的功能是：打印及存储目标函数的目标入参的当前参数值。相应的，如果运行时C程序的目标函数调用时被插桩函数捕获，则行为捕获套件可以遍历调试信息解析结果，查找目标入参，并获取目标入参的当前参数值，可以将当前参数值存储至行为记录数据库中，以通过行为记录数据库对目标入参的当前参数值进行分析和展示。
S231c、将所述调试信息解析结果以及所述调试信息解析结果的关联行为信息存储至行为记录数据库。
所述关联行为信息包括函数调用的时间。
关联行为信息可以是调试信息中调用函数的相关信息，如函数调用的时间等。
可选的，在计算机设备对待处理程序进行动态控制时，如果需要对程序的运行过程进行监控，则可以将调试信息解析结果以及调试信息解析结果的关联行为信息存储至行为记录数据库，以根据行为数据库获取的数据进行可视化展示或分析。
采用上述技术方案，通过预置在待处理程序中的插桩函数获取待处理程序在编译时期生成的调试信息，以对获取的调试信息进行解析得到调试信息解析结果，进而根据调试信息解析结果对待处理程序进行控制，如监控待处理程序内部的运行状态、改变待处理程序的输出打印信息，改变待处理程序的运行行为等。在待处理程序存在故障或需求变更的时候，可以动态改变函数的行为。在硬件损坏的时候，也可以对故障进行降级处理等。能够避免修改代码、重新编译程序、发布及替换软件版本，从而提高程序的控制效率。
