Description

Technical Field

[0001] The present invention relates to the technical field of code data management, and in particular to a code flow tracking method and system. Background Art

[0002] Computer programs are usually composed of a large number of function codes. Each function code is a separate function unit that calculates and processes the input information and outputs the corresponding calculation results. In a computer program, there may be a logical relationship between calling and being called between different function codes. When the computer program is edited, designed and tested, it will be packaged and directly handed over to the user. When the user uses the computer program, it is impossible to visualize the real-time operation of different function codes inside the computer program. When an unexpected failure occurs during the operation of the computer program, the user cannot accurately determine the link corresponding to the function code where the unexpected failure occurs, and cannot track the operation of the computer program in real time, thereby reducing the visualization of the computer program operation monitoring and the safety and stability of the computer program operation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1 , is a flow chart of a code flow tracing method provided by an embodiment of the present invention. The code flow tracing method comprises the following steps:

[0047] Step S1, scanning and analyzing the program, identifying all function codes contained in the program, and assigning corresponding identification tags to each group of function codes; extracting corresponding source code parts and trigger code parts from each group of function codes, thereby forming a code trigger relationship information set within each group of function codes;

[0048] Step S2, collecting the running status information of all function codes of the program during the test running process, and determining the call logic relationship information set between all function codes during the running process of the program according to the running status information; and constructing a call relationship structure model of all function codes according to the identification mark and the call logic relationship information set;

[0049] Step S3, according to the code trigger relationship information set, the trigger relationship of each group of function codes in the call relationship structure model is expanded to obtain an extended call relationship structure model; the extended call relationship structure model is displayed in the form of a visual tracking flowchart.

[0050] The beneficial effects of the above technical solution are as follows: the code flow tracing method analyzes the program to obtain all the function codes it contains, and identifies the source code part and the trigger code part of each group of function codes to obtain a code trigger relationship information set; then, based on the running status information of all function codes in the program during the test running process, the call logic relationship information set between different function codes is determined to construct a call relationship structure model for all function codes; finally, based on the code trigger relationship information set, the call relationship structure model is secondary expanded, and the expanded call relationship structure model is displayed in the form of a visual tracing flowchart, which performs multi-level tracing analysis on the function code of the program from two aspects: the trigger relationship between different code parts within the function code and the call relationship between different groups of function codes, and also dynamically and synchronously displays the corresponding visual tracing flowchart, so as to track the program running status in real time and improve the controllability and security of the program running.

[0051] Preferably, in step S1, the program is scanned and analyzed to identify all function codes contained in the program, and a corresponding identification mark is assigned to each group of function codes; the corresponding source code part and trigger code part are extracted from each group of function codes to form a code trigger relationship information set within each group of function codes, specifically including:

[0052] Step S101, using program static analysis software to scan and analyze the program line by line, identify each function code line contained in the program; then analyze the adjacent function code lines to determine whether the two adjacent function code lines have the same function correlation; if they have the same function correlation, all function code lines with the same function correlation are identified and marked as the same group of function codes;

[0053] Step S102, detecting the same set of function codes to determine whether there is a code editing vulnerability in the same set of function codes; if there is a code editing vulnerability, checking and repairing all codes in the same set of function codes;

[0054] Step S103, extracting the source code part and the trigger code part for running the corresponding function from each group of function codes; constructing a code matching group about the source code part and the trigger code part, the code matching group including the trigger association information between the source code part and the trigger code part; and then combining all the code matching groups together to form a code trigger relationship information set within each group of function codes themselves.

[0055] The beneficial effects of the above technical solution are as follows: computer programs usually include a large number of function codes, and each group of function codes, as an independent function operation unit, can calculate the corresponding input quantity and obtain the corresponding output quantity. Among them, each function code is composed of multiple function code lines. The program static analysis software is used to scan and analyze the computer program as a whole line by line, and all function code lines included in the computer program as a whole can be quickly and accurately identified. Then, each function code line is semantically analyzed and identified to determine whether there is a function semantic association between two adjacent function code lines, that is, whether they have the same function association, and all function code lines belonging to the same function code are identified and marked as the same group of function codes. Then, the code editing vulnerabilities of the same group of function codes are detected and checked and repaired. Finally, the source code part and the trigger code part of the function during operation are lifted from each group of line codes, so that the code trigger relationship within each group of function codes can be determined, so as to form the association of each group of function codes at the code triggering level.

[0056] Preferably, in step S2, the running state information of all function codes of the program during the test running process is collected, and according to the running state information, a call logic relationship information set between all function codes during the running process of the program is determined; and according to the identification mark and the call logic relationship information set, a call relationship structure model of all function codes is constructed, which specifically includes:

[0057] Step S201, collecting function input information and function output information of all function codes of the program during the test operation process, and using this as the operation status information;

[0058] Step S202, determining whether the function output information of one of the function codes belongs to the function input information of another function code, and if so, determining that there is a calling logic relationship between the two function codes, thereby obtaining a calling logic relationship information set between all the function codes during the running of the program;

[0059] Step S203: constructing a call relationship structure model between different groups of function codes according to the identification mark and the call logic relationship information set.

[0060] The beneficial effect of the above technical solution is that in practical applications, each group of function codes of a computer program is used as an independent function operation unit, which can calculate the corresponding input quantity to obtain the corresponding output quantity. The function output information of one function code may be used as the function input information of another function code. The above output-input relationship determines that there is a calling logic relationship between the two function codes, and the calling relationship structure model between all function codes contained in the computer program is formed, so that the computer program can be tracked at the level of the function codes.

[0061] Preferably, in step S3, according to the code trigger relationship information set, the trigger relationship of each group of function codes in the call relationship structure model is expanded to obtain an extended call relationship structure model; and displaying the extended call relationship structure model in the form of a visual tracking flowchart specifically includes:

[0062] Step S301, according to the code trigger relationship information set, the code trigger relationship between the source code part and the trigger code part in each group of function codes included in the call relationship structure model is extended and indexed, thereby obtaining an extended call relationship structure model;

[0063] Step S302, converting the extended call relationship model into a visual tracking flowchart, and synchronously uploading the visual tracking flowchart to the terminal running the program;

[0064] Step S303, when the terminal runs the program, according to the actual progress of the terminal running the program, instruct the visual tracking flowchart to perform dynamic synchronous display.

[0065] The beneficial effect of the above technical solution is: according to the code trigger relationship information set, the code trigger relationship between the source code part and the trigger code part in each group of function codes contained in the call relationship structure model is extended and indexed, so that the computer program can be extended and indexed at two levels: the trigger relationship between different function code lines in the same group of function codes and the call relationship between different groups of function codes, so as to dynamically track and analyze the computer program. In addition, when the terminal runs the program, according to the actual progress of the terminal running the program, the visual tracking flowchart is instructed to be dynamically and synchronously displayed, so that the program running status can be tracked in real time, improving the controllability and security of the program running.

[0076] The beneficial effects of the above technical solution are as follows: computer programs usually include a large number of function codes, and each group of function codes, as an independent function operation unit, can calculate the corresponding input quantity and obtain the corresponding output quantity. Among them, each function code is composed of multiple function code lines. The program static analysis software is used to scan and analyze the computer program as a whole line by line, and all function code lines included in the computer program as a whole can be quickly and accurately identified. Then, each function code line is semantically analyzed and identified to determine whether there is a function semantic association between two adjacent function code lines, that is, whether they have the same function association, and all function code lines belonging to the same function code are identified and marked as the same group of function codes. Then, the code editing vulnerabilities of the same group of function codes are detected and checked and repaired. Finally, the source code part and the trigger code part of the function during operation are lifted from each group of line codes, so that the code trigger relationship within each group of function codes can be determined, so as to form the association of each group of function codes at the code triggering level.

[0077] Preferably, the function code call relationship determination module is used to collect the running state information of all function codes of the program during the test running process, and determine the call logic relationship information set between all function codes during the running process of the program according to the running state information; and constructing the call relationship structure model of all function codes according to the identification mark and the call logic relationship information set specifically includes:
