技术领域technical field
本发明涉及程序调试领域，尤其涉及一种软件在线调试方法和系统。The invention relates to the field of program debugging, in particular to a software online debugging method and system.
背景技术Background technique
目前，在软件开发以及软件开发后的使用过程中，不可避免地会出现各种软件问题。现有的用于定位软件问题的方法包括：运行日志、调试命令、单步追踪。At present, in the process of software development and use after software development, various software problems will inevitably occur. Existing methods for locating software problems include: running logs, debugging commands, and single-step tracing.
上述方法中，运行日志和调试命令需要将产生日志和调试信息的调试指令通过硬编码的方式预先写入软件程序的相应位置。通过硬编码写入的调试指令不易更改和删除，也因为通过硬编码写入的调试不易删除，占用了内存，使得在任意软件位置对软件错误进行定位变得不可行。此外，当技术人员通过硬编码的方式将调试指令写入软件程序的相应位置后，还需要对写入调试指令的软件程序重新进行调度、编译、连接和运行，在软件程序重新运行后，原先软件错误的运行环境可能发生丢失/改变，使软件错误不易复现。In the above method, the running logs and debugging commands need to pre-write the debugging instructions for generating logs and debugging information into corresponding positions of the software program in a hard-coded manner. The debugging instructions written by hard coding are not easy to change and delete, and because the debugging written by hard coding is not easy to delete, it takes up memory, making it impossible to locate software errors at any software location. In addition, after the technician writes the debugging instruction into the corresponding position of the software program by hard coding, it is necessary to re-schedule, compile, connect and run the software program written in the debugging instruction. After the software program is re-run, the original The operating environment of software errors may be lost/changed, making it difficult to reproduce software errors.
上述方法中，单步追踪为每执行完一条语句以后，就会停下来，显示运行情况，这种方法要求技术人员一直在现场以便对每条语句的运行结果进行分析，及时发现错误，并且这种方法更适合单任务的软件程序的调试。而在网络设备的实时软件程序中往往同时有几十个任务在运行、并且任务之间相互关联，单步追踪已不适应。In the above method, the single-step tracking means that after each statement is executed, it will stop and display the running status. This method requires technicians to be on site all the time in order to analyze the running results of each statement and find errors in time, and this This method is more suitable for debugging single-task software programs. However, in the real-time software program of network equipment, there are often dozens of tasks running at the same time, and the tasks are related to each other, so single-step tracking is no longer suitable.

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.
软件开发以及软件开发后的使用过程中，不可避免地会出现各种软件问题。当技术人员想在软件运行之前、甚至软件运行过程中且不终止现有软件运行进程的情况下，对软件进行调试，即可采用下述的实施例记载软件在线调试方法。In the process of software development and use after software development, various software problems will inevitably appear. When technicians want to debug the software before the software is running or even during the running of the software without terminating the running process of the existing software, the following embodiments can be used to record the software online debugging method.
下述实施例记载的软件在线调试方法以程序调用的形式调用在线调试指令，不需要重启软件程序；在执行在线调试程序之前保存软件在被追踪点的当前运行环境，使得调试结束后返回被追踪点时，程序能够在原先的运行环境下继续执行。The software online debugging method described in the following embodiments calls online debugging instructions in the form of program calls without restarting the software program; saves the current running environment of the software at the tracked point before executing the online debugging program, so that it returns to the tracked site after debugging. At this point, the program can continue to execute in the original operating environment.
下面以图1为例详细说明本发明实施例提供的软件在线调试方法，图1为本发明实施例提供的软件在线调试方法流程图。在本发明实施例中实施主体可为通信设备、终端、服务器等设备，所述终端具体为个人电脑(Personal Computer，简称：PC)、台式电脑等等。如图1所示，该实施例具体包括以下步骤：The software online debugging method provided by the embodiment of the present invention is described in detail below by taking FIG. 1 as an example. FIG. 1 is a flow chart of the software online debugging method provided by the embodiment of the present invention. In the embodiment of the present invention, the subject of implementation may be equipment such as communication equipment, a terminal, and a server, and the terminal is specifically a personal computer (Personal Computer, PC for short), a desktop computer, and the like. As shown in Figure 1, this embodiment specifically includes the following steps:
步骤S101、确定软件中的被追踪点；Step S101, determining the tracked point in the software;
具体地，步骤S101包括：通过命令行接收用户输入的设置指令，所述设置指令包括所述软件中被追踪点的地址；将所述被追踪点地址的二进制机器指令反汇编为汇编程序；根据所述汇编程序确定所述被追踪点的位置。Specifically, step S101 includes: receiving a setting instruction input by the user through a command line, the setting instruction including the address of the tracked point in the software; disassembling the binary machine instruction of the address of the tracked point into an assembler; The assembler determines the location of the tracked point.
例如，在vxworks操作系统中，调试人员可以通过命令行启用shell指令，通过“lkup”命令获取C代码函数名对应的地址；通过向“l”命令提供函数的地址来反汇编该函数的二进制机器指令。调试人员可根据需要，通过命令行将函数中任意点作为被追踪点。For example, in the vxworks operating system, debuggers can enable shell instructions through the command line, and obtain the address corresponding to the C code function name through the "lkup" command; disassemble the binary machine of the function by providing the address of the function to the "l" command instruction. The debugger can set any point in the function as the traced point through the command line as needed.
进一步地，还可将函数入口点设置为被追踪点，此时，通过命令行，可直接将函数名作为被追踪点的地址。Furthermore, the function entry point can also be set as the tracked point. At this time, the function name can be directly used as the address of the tracked point through the command line.
通过步骤S101可任意确定软件程序中的被追踪点。Through step S101, the tracked point in the software program can be arbitrarily determined.
步骤S102、当执行到所述被追踪点时，保存所述被追踪点处的软件当前运行环境；Step S102, when executing to the tracked point, save the current running environment of the software at the tracked point;
所述软件当前运行环境包括：CPU寄存器的内容；The current operating environment of the software includes: the contents of the CPU register;
可以理解的是，通过保存CPU寄存器的内容，可在执行完在线调试指令后，使得原有软件程序的执行得以不受影响而继续执行。It can be understood that by saving the contents of the CPU registers, the execution of the original software program can be continued without being affected after the in-circuit debugging instruction is executed.
具体地，步骤S102包括：Specifically, step S102 includes:
当执行到所述被追踪点时，根据在被追踪点生成的跳转指令，跳转至已存储在所述软件中的保护/恢复环境指令；执行所述保护/恢复环境指令中的保护环境指令，保存所述被追踪点处的软件当前运行环境。When executing to the tracked point, jump to the protection/restoration environment instruction stored in the software according to the jump instruction generated at the tracked point; execute the protection environment in the protection/restoration environment instruction An instruction for saving the current running environment of the software at the tracked point.
步骤S103、调用已存储的在线调试指令，执行调试任务，输出在线调试信息；Step S103, call the stored online debugging instruction, execute the debugging task, and output the online debugging information;
具体地，步骤S103包括：Specifically, step S103 includes:
执行所述保护/恢复环境指令；当执行到所述保护/恢复环境指令中的跳转点时，通过所述跳转点，跳转至所述在线调试指令；Execute the protection/restoration environment instruction; when the jump point in the protection/restoration environment instruction is executed, jump to the online debugging instruction through the jump point;
执行所述在线调试指令，输出在线调试信息。Execute the online debugging instruction, and output online debugging information.
进一步地，在本步骤中，输出的在线调试信息包括：被追踪点的执行时间、当前CPU各寄存器的状态、当前任务堆栈信息。上述信息包括了执行在线调试指令中关于当前调试任务在被追踪点处执行的所有信息，依据上述信息，以使得调试人员判断在被追踪点的执行是否存在异常，以及当出现异常时，对异常进行定位。Further, in this step, the output online debugging information includes: the execution time of the tracked point, the state of each register of the current CPU, and the stack information of the current task. The above information includes all information about the execution of the current debugging task at the tracked point in the execution of the online debugging command. According to the above information, the debugger can judge whether there is an exception in the execution of the tracked point, and when an exception occurs, correct the exception. to locate.
需要说明的是，在本发明实施例中，所述在线调试信息可包括多层级在线调试，例如，包括第一层级在线调试信息、第二层级在线调试信息等等。It should be noted that, in the embodiment of the present invention, the in-circuit debugging information may include multi-level in-circuit debugging, for example, including first-level in-circuit debugging information, second-level in-circuit debugging information, and so on.
可以理解的是，在本发明实施例中，在执行第一层级在线调试信息时，可通过第一层级在线调试信息中的跳转点，跳转至第二层级在线调试信息中继续进行调制，进而实现多层级在线调试。It can be understood that, in the embodiment of the present invention, when the first-level in-circuit debugging information is executed, the jump point in the first-level in-circuit debugging information can be used to jump to the second-level in-circuit debugging information to continue modulation, And then realize multi-level online debugging.
步骤S104、恢复所述软件当前运行环境，从所述被追踪点处继续执行所述软件后续程序。Step S104, restoring the current operating environment of the software, and continuing to execute the subsequent program of the software from the tracked point.
具体地，步骤S104包括：Specifically, step S104 includes:
当输出在线调试信息后，从所述在线调试指令跳转回所述跳转点；执行所述保护/恢复环境指令中的恢复环境指令，并跳转回所述被追踪点，从所述被追踪点处继续执行所述软件后续程序。After the online debugging information is output, jump back from the online debugging instruction to the jump point; execute the recovery environment instruction in the protection/restoration environment instruction, and jump back to the tracked point, from the The follow-up program of the software continues to be executed at the tracking point.
进一步地，当涉及多层级在线调试时，当前层级在线调试结束后，跳转回至前一层级的跳转点处，执行前一层级跳转点之后的程序，依次跳转回至原软件程序中。Further, when multi-level online debugging is involved, after the current level of online debugging is completed, jump back to the jump point of the previous level, execute the program after the jump point of the previous level, and then jump back to the original software program in turn middle.
需要说明的是，在本发明实施例中，还可根据设置的被追踪点的个数，存储相等数量的保护/恢复环境指令，以使得执行到每个被追踪点处时，方便、灵活地进行跳转。It should be noted that, in the embodiment of the present invention, an equal number of protection/restoration environment instructions can also be stored according to the set number of tracked points, so that when executing to each tracked point, it is convenient and flexible Make the jump.
进一步地，在本发明实施例中，还自动存储被追踪点的位置和被追踪点处二进制机器指令，以便在被追点处进行跳转或者回调。例如，通过直接写内存方式，将被追踪点地址处的内存修改为“保护/恢复环境指令”程序段的起始地址处，进而实现跳转；并将被追踪点处二进制机器指令添加到“保护/恢复环境指令”程序段的末尾处，进而实现回调。Further, in the embodiment of the present invention, the position of the tracked point and the binary machine instruction at the tracked point are also automatically stored, so as to perform jump or callback at the tracked point. For example, by directly writing the memory, the memory at the address of the tracked point is modified to the starting address of the "protection/restoration environment instruction" program segment, and then the jump is realized; and the binary machine instruction at the tracked point is added to the " Protect/Restore Environment Instructions" program segment, and then implement the callback.
通过应用本发明实施例的上述步骤S101-步骤S104，在软件程序运行时，动态设置被追踪点，通过设置的被追踪点，保存被追踪点处的软件当前运行环境；调用已存储的在线调试指令，执行调试任务，输出在线调试信息；并恢复软件当前运行环境，从被追踪点处继续执行软件后续程序。避免了将调试指令直接以硬编码的形式写入软件程序中，而是以程序调用的形式调用调试指令，方便了调试指令的修改与删除，实现在调试过程中任意更改调试指令；同时，也不需要重启软件程序。By applying the above steps S101 to S104 of the embodiment of the present invention, when the software program is running, the tracked point is dynamically set, and the current running environment of the software at the tracked point is saved through the set tracked point; the stored online debugging is called Instructions, execute debugging tasks, output online debugging information; and restore the current operating environment of the software, and continue to execute the subsequent software programs from the tracked point. It avoids writing the debugging instructions directly into the software program in the form of hard coding, but calls the debugging instructions in the form of program calls, which facilitates the modification and deletion of debugging instructions, and realizes arbitrarily changing debugging instructions during the debugging process; at the same time, it also There is no need to restart the software program.
可选地，在上述实施例通过步骤S101确定了软件中的被追踪点之后，还包括接收用户输入的被追踪点删除指令，根据该指令删除被追踪点的步骤，通过该步骤可使调试过程更加方便、灵活。具体步骤如下：Optionally, after the above-mentioned embodiment determines the tracked point in the software through step S101, it also includes the step of receiving a tracked point deletion instruction input by the user, and deleting the tracked point according to the instruction. Through this step, the debugging process can More convenient and flexible. Specific steps are as follows:
通过命令行，接收用户输入的被追踪点删除指令，所述被追踪点删除指令包括待删除的所述被追踪点的位置；receiving a tracked point deletion instruction input by a user through a command line, the tracked point deletion instruction including the location of the tracked point to be deleted;
将待删除的所述被追踪点的位置还原为设置所述被追踪点之前的二进制机器指令；restoring the position of the tracked point to be deleted to the binary machine instruction before setting the tracked point;
当执行到原所述被追踪点的位置时，执行所述二进制机器指令，这样程序就表现为设置被追踪点之前的行为。When executing to the original position of the tracked point, the binary machine instruction is executed, so that the program behaves as before the tracked point is set.
具体地，通过命令行，接收用户输入的被追踪点删除指令，将被追踪点的位置还原为设置被追踪点之前的二进制机器指令；进而当软件执行到原被追踪点所在的位置时，由于此位置已没有被追踪点，则执行设置被追踪点之前的二进制机器指令，使程序恢复为设置被追踪点之前状态。由此可见，本发明实施例相对于现有技术，不仅可以在线设置被追踪点，还可在线删除被追踪点，使调试过程更加灵活。Specifically, through the command line, the tracked point deletion command input by the user is received, and the position of the tracked point is restored to the binary machine instruction before setting the tracked point; and when the software is executed to the original position of the tracked point, because There is no tracked point at this position, then execute the binary machine instruction before setting the tracked point to restore the program to the state before setting the tracked point. It can be seen that, compared with the prior art, the embodiment of the present invention can not only set the tracked point online, but also delete the tracked point online, so that the debugging process is more flexible.
可选地，上述方法中，在上述步骤S103执行调试任务过程中，还包括接收用户输入的被追踪点状态查看指令，根据该指令向用户反馈被追踪点的状态信息的步骤，通过该步骤可方便调试人员判断在被追踪点的执行动作是否异常，并在出现异常时分析原因。具体步骤如下：Optionally, in the above method, in the process of executing the debugging task in the above step S103, it also includes the step of receiving the status check instruction of the tracked point input by the user, and feeding back the status information of the tracked point to the user according to the instruction. Through this step, It is convenient for debuggers to judge whether the execution action at the tracked point is abnormal, and to analyze the cause when an exception occurs. Specific steps are as follows:
在执行调试任务的过程中，通过命令行，接收用户输入的被追踪点状态查看指令；In the process of executing the debugging task, through the command line, receive the status viewing instruction of the tracked point input by the user;
根据所述查看指令，向所述用户反馈所述软件中被追踪点的状态信息，所述被追踪点的状态信息包括以下一种或多种：According to the viewing instruction, the status information of the tracked point in the software is fed back to the user, and the status information of the tracked point includes one or more of the following:
被追踪点的执行时间、当前CPU各寄存器的状态、当前任务堆栈信息。The execution time of the tracked point, the status of each register of the current CPU, and the stack information of the current task.
具体地，在执行调试任务的过程中，当接收到用户输入的被追踪点状态查看指令时，根据查看指令，向用户反馈软件中被追踪点的状态信息。Specifically, in the process of executing the debugging task, when receiving the status check command of the tracked point input by the user, the status information of the tracked point in the software is fed back to the user according to the check command.
进一步地，被追踪点的状态信息还包括：软件程序中全部设置的被追踪点的设置信息，例如，被追踪点的设置位置、执行次数等等。Further, the status information of the tracked point also includes: setting information of all the tracked points set in the software program, for example, the setting position of the tracked point, the number of times of execution, and the like.
上述被追踪点的状态信息可方便调试人员判断在被追踪点的执行动作是否异常，并在出现异常时分析原因，同时，调试人员还可根据被追踪点的状态信息对被追踪点进行重设置。The above status information of the tracked point can facilitate the debugger to judge whether the execution action at the tracked point is abnormal, and analyze the cause when an exception occurs. At the same time, the debugger can also reset the tracked point according to the status information of the tracked point .
可选地，上述方法中，在步骤S103输出在线调试信息后，还可将该在线调试信息保存进内存，方便调试人员查阅，避免了调试人员一直守候在现场。Optionally, in the above method, after the online debugging information is output in step S103, the online debugging information can also be saved in the memory, which is convenient for the debugging personnel to check, and avoids the debugging personnel waiting at the scene all the time.
通过应用本发明实施例的提供的软件在线调试方法，在软件程序运行时，动态设置被追踪点，通过设置的被追踪点，保存被追踪点处的软件当前运行环境；调用已存储的在线调试指令，执行调试任务，输出在线调试信息；并恢复软件当前运行环境，从被追踪点处继续执行软件后续程序。由于在本发明实施例中，通过设置的被追踪点调用已存储的在线调试指令，并在被追踪点处进行软件当前运行环境的保存/恢复，避免了将调试指令直接以硬编码的形式写入软件程序，而是以程序调用的形式调用调试指令，方便了调试指令的修改与删除，实现在调试过程中任意更改调试指令；同时，也不需要重启软件程序；另外，上述技术方案在调用调试指令，执行调试程序之前保存软件当前运行环境，使得调试结束后返回被追踪点时，程序能够继续在原先的运行环境下执行，避免了对原软件程序的影响。By applying the software online debugging method provided by the embodiment of the present invention, when the software program is running, the tracked point is dynamically set, and the current running environment of the software at the tracked point is saved through the set tracked point; the stored online debugging is called Instructions, execute debugging tasks, output online debugging information; and restore the current operating environment of the software, and continue to execute the subsequent software programs from the tracked point. Since in the embodiment of the present invention, the stored online debugging instructions are invoked through the set tracked point, and the current running environment of the software is saved/restored at the tracked point, it is avoided to directly write the debugging instruction in a hard-coded form. Instead of entering the software program, the debugging instruction is called in the form of program call, which facilitates the modification and deletion of the debugging instruction, and realizes any modification of the debugging instruction during the debugging process; at the same time, there is no need to restart the software program; in addition, the above technical solution is called Debugging instructions, save the current running environment of the software before executing the debugging program, so that when the debugging ends and returns to the tracked point, the program can continue to execute in the original running environment, avoiding the impact on the original software program.

The whole process is debugged by calling the program. It is not necessary to write the debugging instructions into the tracked point in the software through the steps of coding, compiling and linking. Since the software is always running in the memory, there is no need to restart the program to save the modified The software is loaded into memory to run.
本发明实施例提供的软件调试流程，当输出在线调试信息后，从在线调试指令跳转回跳转点；执行保护/恢复环境指令中的恢复环境指令，并跳转回被追踪点，从被追踪点处继续执行软件后续程序。由于程序能够继续在原先的运行环境下执行，避免了调试对原软件程序的影响。In the software debugging process provided by the embodiment of the present invention, after the online debugging information is output, jump back from the online debugging instruction to the jump point; execute the recovery environment instruction in the protection/restoration environment instruction, and jump back to the tracked point, from the Continue to execute the software follow-up program at the tracking point. Since the program can continue to be executed in the original operating environment, the influence of debugging on the original software program is avoided.
