-First embodiment-
Hereinafter, a first embodiment of the influence output system will be described with reference to FIGS. 1 to 13.

(Definition of terms)
In the present embodiment, a person who operates a terminal device described later is referred to as a "user". Also, in the following, a document that describes a process to be executed by a computer, and a sentence that is decoded and processed by a compiler or interpreter of the computer is referred to as “source code”. The functions and variables described in the source code are called "elements". Changing the description of the elements described in the source code and adding the description of the elements to the source code is called "modification" of the source code.

(Constitution)
FIG. 1 is a diagram showing a system configuration of the influence output system 1. The influence output system 1 includes a terminal device 100 operated by a user, and a server 200 connected to the terminal device 100 via a network. That is, the terminal device 100 can be regarded as a client in relation to the server 200.

  The terminal device 100 includes a terminal processing unit 110, a terminal storage unit 120, a display unit 130, an input unit 140, and a terminal communication unit 150. The terminal processing unit 110 is, for example, a CPU, and performs functions described below by expanding a program stored in a ROM (not shown) into a RAM (not shown) and executing the program. The terminal processing unit 110 includes, as its functions, a call relation detecting unit 111, a simultaneous correction relation detecting unit 112, an influence point analysis judging unit 113, an input / output processing unit 114, and a correction difference detecting unit 115. The call relation detection unit 111 detects a reference relation between functions and variables included in the source code based on a known static analysis technology, and creates a call relation database (hereinafter called a call relation DB) 121 described later.

  The simultaneous correction relationship detection unit 112 creates a simultaneous correction relationship database (hereinafter, simultaneous correction relationship DB) 122 described later, based on a plurality of source codes acquired from the server 200, that is, the correction history of the source code. The influence point analysis determination unit 113 determines another element that the change of a certain element affects. The input / output processing unit 114 is connected to the display unit 130 and the input unit 140 via an input / output interface (not shown). The input / output processing unit 114 outputs the video information to the display unit 130 and accepts input information from the input unit 140. The correction difference detection unit 115 detects the difference of the source code on an element basis. That is, it detects added functions and variables and modified functions.

  The terminal storage unit 120 is a non-volatile data storage device such as a hard disk drive or a flash memory. In the terminal storage unit 120, a call relation DB 121, a simultaneous correction relation DB 122, a registration source code 123, and a correction source code 124 are stored. As described above, the call relation DB 121 is generated by the call relation detection unit 111, and the simultaneous correction relation DB 122 is generated by the simultaneous correction relation detection unit 112. The call relation DB 121 stores information indicating a call relation between elements obtained by analyzing source code, that is, a relation between calls and a relation between calls. As described above, the call relation DB 121 is generated by the call relation detection unit 111. The simultaneous correction relationship DB 122 stores information indicating elements to be corrected simultaneously.

  The registration source code 123 is a latest set of source code registered in the server 200, and is acquired from the server 200 via the terminal communication unit 150. The modified source code 124 is a source code in which the registered source code 123 is modified by the user. That is, the terminal processing unit 110 first acquires the latest set of source code from the server 200, stores it as the registered source code 123, and provides the same to the user via the display unit 130. When the user modifies the source code using the input unit 140, the terminal processing unit 110 stores the modified source code in the terminal storage unit 120 as the modified source code 124.

  The display unit 130 is, for example, a liquid crystal display, and provides visual information to the user based on an operation command of the terminal processing unit 110. The input unit 140 is, for example, a keyboard or a mouse, and receives user's input and transmits it to the terminal processing unit 110. The terminal communication unit 150 communicates with the server 200 by wired or wireless communication.

  The server 200 includes a server processing unit 210 and a server storage unit 220. The server processing unit 210 is, for example, a CPU. The server storage unit 220 is a non-volatile data storage device such as a hard disk drive or a flash memory. The server storage unit 220 stores a configuration management database (hereinafter, configuration management database DB) 221. The configuration management DB 221 includes source code of a plurality of revisions, which is a source code modification history, and history information. Details of the configuration management DB 221 will be described later.

(Configuration Management DB)
FIG. 2 is a diagram showing the configuration of the configuration management DB 221 provided in the server 200. As shown in FIG. The configuration management DB 221 stores source code groups 223 of a plurality of revisions and history information 225. Each revision source code group includes one or more source code. A larger revision number indicates that the creation date is newer, and the revision 84 is the latest source code registered in the configuration management DB 221.

  FIG. 3 is a diagram showing an example of the history information 225. As shown in FIG. The history information 225 is composed of a plurality of records, and each record is composed of the fields of version 226, revision 227, date and time 228, correction file 229, person in charge 230, and message 231. A version number is stored in the version 226 field. However, the version number is assigned according to a predetermined condition, and some records do not have a version number. The field of the revision 227 stores a number which is updated each time the source code is registered in the configuration management DB 221. In the field of date and time 228, the date and time when the revision was registered in the configuration management DB 221 is stored. The field of the correction file 229 stores the name of the file corrected from the previous revision in the revision. The field of the person in charge 230 stores the name of the person in charge who has registered the revision. In the field of the message 231, a message regarding the revision is stored. However, the field of the message 231 may not be stored.

  The history information 225 is created by the server processing unit 210. When receiving the source code from the terminal device 100, the server processing unit 210 assigns a new revision number and stores it in the configuration management DB 221 and generates a new record of the history information 225. This record stores the assigned new revision number, the time when the source code was received, the name of the received source code, the name of the person in charge associated beforehand with the terminal apparatus 100 that transmitted the source code, and the received message. Ru. However, when the message is not received, nothing is input in the field of the message 231.

(Example of element)
FIG. 4 is a diagram showing an example of the interrelationship between functions and variables that are elements. In FIG. 4, the function is represented by a combination of "Func" and one alphabet, and the variable is represented by a combination of "Value" and one alphabet. The one-way arrows in FIG. 4 indicate that they are in a calling / called relationship, and the two-way arrows indicate that they are in a simultaneous correction relationship. That is, FIG. 4 shows that FuncG calls FuncA, FuncA calls ValueA and FuncD, and FuncD calls FuncH. FIG. 4 also shows that FuncB calls FuncC and FuncC calls FuncE and FuncI. Further, FIG. 4 shows that FuncA and FuncC have a simultaneous correction relationship, and FuncD and FuncF have a simultaneous correction relationship.

  Furthermore, in the present embodiment, the perspective of the relationship between elements is expressed using “stages”. One call between elements, one to be called, and one simultaneous correction relation are one stage each, and the number of stages is added each time the relation goes away. For example, in the example shown in FIG. 4, since FuncA calls FuncD and FuncD has FuncD's simultaneous correction relationship, FuncF based on FuncA is "call, simultaneous correction" when tracing the relationship between elements in order. "One call stage, simultaneous correction one stage". Similarly, in the example illustrated in FIG. 4, FuncH based on FuncB is “call, simultaneous correction, call, call” when it follows the relationship between elements, and thus “call 3 stage, simultaneous correction 1 stage”.

  FIG. 5 is a diagram showing an example of the definitions of FuncA and FuncH described in source code. As shown in FIG. 3, FuncD is called inside FuncA, and ValueA is passed as an argument. In such a relation, FuncA is in a relation of calling ValueA and FuncD, and ValueA and FuncD are in a relation of being called by FuncA, that is, in a relation of being called. FuncH is a function that takes two arguments, performs an operation using these two arguments, and returns an operation result. FuncH does not call any elements because FuncH does not refer to functions and variables. Therefore, in FIG. 4, the one-way arrow starting from FuncH does not extend.

(Call relationship DB)
FIG. 6 is a diagram showing an example of the call relation DB 121. As shown in FIG. The example shown in FIG. 6 corresponds to the interrelationship shown in FIG. The call relation DB 121 includes an element table 410 and a call relation table 420. The element table 410 is configured of a plurality of records, and each record includes fields of an element ID 411, a file 412, and a function / variable 413. In the field of element ID 411, an ID for specifying an element is stored. The ID is, for example, a number, and the number of digits and the number of numbers are not limited as long as they are different from other elements. The field of the file 412 stores the file name in which the element is defined. The field of the function / variable 413 stores the name of the element.

  The call relation table 420 is composed of a plurality of records, and each record includes fields of a correction source element ID 421, a correction influence element ID 422, and a relation 423. The field of the correction source element ID 421 stores the element ID of the element to be corrected. The field of the modification influence element ID 422 stores the element ID of the element that is affected by the modification due to the calling relationship and the called relationship. The field of the relationship 423 stores which of the relationship between the call and the call is received.

(Simultaneous correction relation DB)
FIG. 7 is a diagram showing an example of the simultaneous correction relationship DB 122. As shown in FIG. The example shown in FIG. 7 corresponds to the interrelationship shown in FIG. The simultaneous correction relation DB 122 is a database showing elements corrected for each revision registered in the configuration management DB 221 of the server 200. For example, as shown in FIG. It is expressed in the form of a table in which It shows that the element of the column in which the circle is described in FIG. 7 has been corrected. For example, it is shown in FIG. 7 that FuncA and FuncC have been corrected at revision 01, that is, the differences between revision 00 and revision 01 are at FuncA and FuncC.

  By using the simultaneous correction relationship DB 122, it is possible to detect an element which is not related to calling and is not related to calling on the software, but is related to functions and operations and affects the correction. For example, in the modification of the function of fast-forwarding voice, it is conceivable that voice processing and the user interface displayed on the display unit 130 are closely related, but both are not in a calling relationship in the source code. Even in such a case, it can be seen that when the elements related to speech processing are corrected by referring to the simultaneous correction relation DB 122, the elements related to the user interface are also affected.

(Screen display)
FIG. 8 is a diagram showing an example of the correction influence check screen 901 displayed on the display unit 130. As shown in FIG. The correction influence check screen 901 includes a pre-correction input field 902, a post-correction input field 903, an analysis start button 904, and a list output field 905. After modifying the source code, the user calls the modification impact check screen 901 to check the range affected by the modification. More specifically, the user first calls up the correction impact check screen 901 by inputting to the input unit 140, inputs the directory of the source code before correction into the input column before correction 902, and inputs the directory of the source code after correction after correction Input in the column 903. Then, when the user presses the analysis start button 904, an influence output list 900, which is a list of elements affected by the corrected element, is displayed in the list output column 905. In other words, the influence output list 900 displays the corrected element and all elements in the calling relation, the called relation, and the simultaneous correction relation.

  FIG. 9 is a diagram showing an example of the influence output list 900 displayed in the list output field 905. As shown in FIG. The influence output list 900 includes a correction element column 1101 indicating a correction element which is a correction element, a correction influence column 1102 indicating a relation between an influence element which is an element that the correction affects, and a correction element; An immediate relationship column 1103 indicating an element that affects immediately before an influence element. Among these three fields, the user pays particular attention to the revision impact column 1102 to check if there is any omission. In the modification impact column 1102, the relationship between the factor that the modification affects and the factor that has been modified is stored as a modification impact type 1104. In the modified influence type 1104, the relationship between each element from the corrected element to the affecting element is represented in order. For example, in the example shown in FIG. 4, when FuncA is modified, it affects FuncF through FuncD. More specifically, since it is FuncF that has a simultaneous modification relationship with FuncD which FuncA calls, the modification influence type 1104 of FuncF becomes "call, simultaneous modification" which describes the relationship in order. When FuncB is corrected in the example of FIG. 4, the affected influence type 1104 of FuncH becomes “call, simultaneous correction relation, call, call”.

  The elements described in the immediate relationship column 1103 are useful information when the corrected element affects other elements through one or more elements. For example, as in the above-described example, FuncF that is affected via FuncD when the FuncA is modified, FuncD, which is a factor directly affecting FuncF, is described in the immediate relationship column 1103. In the example of FIG. 4, for FuncG, ValueA, FuncD, and FuncC, which are directly affected by FuncA, FuncA which is the element itself corrected is stored in the immediately preceding relationship column 1103.

  Since the influence output list 900 described above has the correction influence type 1104, it is possible to present the user with the relation between the corrected element and the influence element. In particular, since it is easy to overlook relationships such as elements in the simultaneous correction relationship of the call participant and elements in the call relationship of the simultaneous correction relationship, the influence output list 900 capable of presenting these at one time is useful.

-flowchart-
The operation of the terminal device 100 for realizing the functions described above will be described using a flowchart.

(Process of registration to server)
FIG. 10 is a flowchart showing registration processing of a source code to the configuration management DB 221 of the server 200 by the terminal device 100. The CPU (not shown) of the terminal device 100 executes a program whose operation is shown in FIG. 10 based on an input operation to the input unit 140 by the user. However, the CPU may execute the program under predetermined conditions, for example, when a certain time has elapsed. The execution subject of each step described below is a CPU (not shown) of the terminal device 100.

  In step S301, the CPU uses the correction difference detection unit 115 to compare the registered source code 123 with the correction source code 124. In the following step S302, the CPU determines whether there is a difference between the element of the registered source code 123 and the element of the modified source code 124. If it is determined that there is a difference in any of the elements, that is, if it is determined that some correction has been made, the process proceeds to step S303. If it is determined that there is no difference, the flowchart illustrated in FIG. In step S303, the source code that has been corrected is transmitted to the server 200 via the terminal communication unit 150, and the flowchart illustrated in FIG. 10 is ended. At that time, the user can optionally add a message. The message added here is recorded as a message 231 of the history information 225.

(Process for creating call relation DB)
FIG. 11 is a flowchart showing the process of creating the call relation DB 121 by the call relation detection unit 111. The call relation detection unit 111 executes a program whose operation is represented by the following flowchart when the correction effect check screen 901 is called, when the correction source code 124 is updated, or when a predetermined time elapses. The execution subject of each step described below is a CPU (not shown) of the terminal device 100.

  In step S501, the CPU determines a source code to be processed. For example, when a complete source code consists of four files A to D, registered source code 123 stores all four files acquired from server 200, and modified source code 124 includes files modified by the user, for example, among them Only A is stored. In this case, the CPU determines A to be stored in the correction source code 124 and B to D stored in the registration source code 123 as processing targets.

  In the following step S502, all elements, that is, all functions and variables are extracted and listed from the source code to be processed. In the following step S503, the processing of the following steps S504 to S505 is executed on the respective elements extracted in step S502 as processing targets. In step S504, the CPU measures the calling relationship and the called relationship regarding the element to be processed. In the following step S505, the measurement result obtained in step S504 is recorded in the call relation DB 121. In the following step S506, it is determined whether the processing in S504 to S505 is completed for all the elements listed in step S502. If the CPU determines that the process has not been completed, the CPU selects the next element and executes the process of step S504. If the CPU determines that the process is completed, the flowchart illustrated in FIG.

(Process of creating simultaneous correction relationship DB)
FIG. 12 is a flowchart showing creation processing of the simultaneous correction relation DB 122 by the simultaneous correction relation detecting unit 112. The simultaneous correction relation detection unit 112 executes a program whose operation is represented by the following flowchart when the correction influence check screen 901 is called, the correction source code 124 is updated, or when a predetermined time elapses. The execution subject of each step described below is a CPU (not shown) of the terminal device 100.

  In step S701, the CPU acquires, from the configuration management DB 221 of the server 200, all source code necessary for comparison between revisions. In other words, the source code correction history is acquired in step S701. The field of the correction file 229 included in the history information 225 of the server 200 describes the name of the file that has been corrected from the previous revision, so the CPU specifies the file to be acquired by referring to this .

In the following step S702, the current revision and the previous revision are selected as the processing target. For example, in the example shown in FIG. 3, since the revision 84 is the latest, the revisions 84 and 83 are selected for processing here. In the subsequent step S703, the CPU uses the correction difference detection unit 115 to extract the elements corrected in the two revisions to be processed. In the subsequent step S704, the element extracted in step S703 is registered in the simultaneous correction relation DB 122. In the following step S705, the CPU determines whether all revisions have been processed. If it is determined that all revisions are to be processed, the flowchart shown in FIG. 12 is ended. If it is determined that there are revisions not to be processed, the process proceeds to step S706. In step S706, the CPU selects the older one of the two selected revisions and the previous revision as a processing target, and returns to step S703. For example, if the revisions selected immediately before the execution of step S706 are the revision 84 and the revision 83, the revision 83 and the revision 82 are selected as the next processing target by executing the step S706.
By the above processing, the elements corrected among all the revisions are extracted and registered in the simultaneous correction relation DB 122.

(Display process of impact output list)
FIG. 13 is a flow chart showing processing executed when the analysis start button 904 shown in FIG. 8 is pressed. The execution subject of each step described below is a CPU (not shown) of the terminal device 100.

  The CPU first executes steps S801 and S802. In step S801, the CPU reads the modified source code 124 and the registered source code 123. In the subsequent step S 803, the CPU uses the correction difference detection unit 115 to extract a correction element that is a corrected element, and also extracts all the elements described in the correction source code 124 and the registration source code 123. For example, if the registered source code 123 is composed of three source codes A1, B1 and C1 and only A1 is modified to become A2, then the modified source code 124 is composed only of A2. In this case, in step S803, extraction of correction elements is performed by comparison of A1 and A2, and extraction of all elements is performed using B1, C1, and A2.

  Since the list of correction elements and all elements extracted in this step is used later, the CPU stores them in a RAM (not shown). In the following step S804, the CPU selects an unanalyzed element from among the correction elements extracted in step S803 as an analysis target element. In the first execution of step S804, no element is analyzed, so an arbitrary element is selected. The element selected here is an analysis target in steps S806 and S807, and is hereinafter referred to as an analysis target element. In step S802, which is executed simultaneously with step S801, the CPU reads the simultaneous correction relation DB 122.

  In step S806, which is executed after step S804, the CPU analyzes the modified source code 124 and the registered source code 123, and lists up an analysis target element, a calling relation, and an element in a called relation. In step S807, which is executed when the execution of step S804 and step S802 is completed, elements which are in a simultaneous correction relationship with the analysis target element are listed up. The detailed operation of this step S 807 will be described with reference to FIG. In step S808, which is executed when the execution of step S806 and step S807 is completed, it is determined in step S806 and step S807 whether at least one element is listed. If the CPU determines that at least one element is listed up, it proceeds to step S809, and if it determines that no element is listed up, it proceeds to step S810.

  In step S809, the CPU determines whether or not the listed elements include an unparsed element. If the CPU determines that an unanalyzed element is included, the process proceeds to step S811. If the CPU determines that an unanalyzed element is not included, the process proceeds to step S810. In step S810, the CPU determines whether the correction element extracted in step S803 has been analyzed. If it is determined that all the correction elements have been analyzed, the process proceeds to step S812. If it is determined that the correction elements not analyzed remain, the process returns to step S804. In step S811, the CPU selects any unanalyzed element among the elements listed up in step S806 and step S807, and returns immediately after step S804. In step S812, which is executed when an affirmative determination is made in step S810, the CPU uses input / output processing unit 114 to analyze all elements listed up in steps S806 and S807, and to call or simultaneously correct them. And the output unit 900 as the influence output list 900. For example, in the example shown in FIG. 9, the elements listed when FuncA is made an analysis target element are shown, and the field of the correction influence type 1104 shows the relationship with the function. By the above processing, the influence output list 900 is displayed in the list output field 905 on the correction influence check screen 901.

(Detailed flowchart)
FIG. 14 is a flowchart showing details of step S 807 of FIG. As described with reference to FIG. 13, the analysis target element is selected when the process of the flowchart illustrated in FIG. 14 is started.

  In step S1201, the CPU selects one of all elements extracted in step S803 in FIG. 13 as a comparison target. In the following step S1202, the CPU refers to the simultaneous correction relationship DB 122, and counts the number of simultaneous corrections of the analysis target element and the comparison target element. More specifically, since the simultaneous correction relation DB 122 shows elements corrected at each revision as indicated by circles in FIG. 7, both the analysis target element and the comparison target element for all revisions are shown. Count the number of revisions that are circled. In the following step S1203, it is determined whether the number of counts in step S1202 is three or more. If it is determined that the number of times is three or more, the process proceeds to step S1204 and is listed up, and then the process proceeds to step S1205. If it is determined that the number is less than three times, the process directly proceeds to step S1205.

  In step S1205, the CPU determines whether all the elements extracted in step S803 have been selected as comparison targets. If it is determined that all the elements have been selected, the flowchart in FIG. If it is determined that there is, the process proceeds to step S1206. In step S1206, elements which have not been selected in step S1201 and this step are selected from all the elements extracted in step S803 in FIG. 13, and the process returns to step S1202. By the above processing, the elements having the simultaneous correction relation with the analysis target element are listed up. The simultaneous correction relationships indicated by the double-headed arrows in the relationships between the elements illustrated in FIG. 4 represent those listed up by the process of FIG. Although the threshold is set to "3" in step S1203, another value may be used.

(Operation example)
If there is a relationship between the elements illustrated in FIG. 4 and the element detected as the difference in step S 803 in FIG. 13 is FuncA, the influence output list 900 is output in step S 804 onward in FIG. Explain. Although the influence output list 900 is output in step S812 in the above-described flowchart, the influence output list 900 is appropriately output in order to clarify the correspondence with the operation in this operation example.

  First, in step S804, FuncA is selected, and steps S806 and S807 are executed. In step S806, "Value A", "Func G", and "F unc D" which are in a calling relationship and a called relationship are listed up, and based on this, the first to third lines of the influence output list 900 shown in FIG. Ru. That is, these modification influence types 1104 are output as "call", "called", and "call", respectively. This is the influence range of the first stage of the calling relationship. In step S 807, “FuncC” that is in a simultaneous correction relationship with FuncA is listed, and the correction influence type 1104 is output as “simultaneous correction” in the fourth line of FIG. 9. This is the influence range of the first stage of the simultaneous correction relationship.

  Since each list is listed in step S806 and step S807, step S808 is affirmed, and none of the listed elements is analyzed, so step S809 is also affirmed. Then, one of the elements listed up in step S811, for example, FuncD, is selected as the analysis target element. Then, FuncHs in a calling relationship are listed up (S806), and FuncFs in a simultaneous correction relationship are listed up (S807). This FuncH becomes a second stage call relation from the correction element FuncA via the FuncD described in the column 1103 of the immediate relation. Therefore, in the influence output list 900 shown in FIG. 9, the modification influence type 1104 stores “call, call”. By displaying in this manner, the user can accurately grasp the relationship with the correction element.

  Similarly, on the sixth line of the influence output list 900 shown in FIG. 9, FuncF on the sixth line is a call relation via one FuncD described in the immediately preceding relation column 1103 from FuncA which is a correction element and a simultaneous correction relation one stage. It becomes. Therefore, in the influence output list 900 shown in FIG. 9, the correction influence type 1104 displays "call, simultaneous correction". In steps S 808 to S 809, since the positive determination is made in the same manner as described above, the analysis processing is repeated until there are no unanalyzed elements.

According to the first embodiment described above, the following effects can be obtained.
(1) For a plurality of elements which are functions or variables described respectively in the source code, a correction history of the source code, that is, a simultaneous correction relation DB 122 in which a combination of elements corrected simultaneously in the differences for each revision is recorded Terminal memory unit 120, a correction element identification unit (step S803 in FIG. 13) for specifying a correction element to be corrected among a plurality of elements, and being affected by correcting a correction element among a plurality of elements An influence location analysis determination unit 113 which determines and outputs an influenced element using the simultaneous correction relationship DB 122.
Therefore, based on having been corrected at the same time in the past, when one of them is corrected, the other is output, so that it is possible to detect an element that is likely to be corrected at the same time be able to. For example, even if the processing related to display and the processing related to the function are not in the calling relation on the source code, by referring to the simultaneous correction relation DB 122 indicating the past simultaneous correction relation, the element having the function or operation relation is detected. It can be output to alert the user.

(2) The terminal storage unit 120 stores a call relation DB 121 in which the call relation of the elements in the source code is recorded. The affected part analysis / determination unit 113 determines the influenced element using the simultaneous correction relation DB 122 and the call relation DB 121. Therefore, the influence point analysis / determination unit 113 can output not only the elements in the simultaneous correction relationship but also the elements in the call relationship and the elements in the multiple relationship between the simultaneous correction relationship and the call relationship to the influence output list 900. . That is, it is possible to output an element that is affected by correction, which is overlooked if only one of the calling relation and the simultaneous correction relation is focused on.

(3) The influential part analysis / determination part 113 determines the influential element based on the combination of elements whose number of times of simultaneous correction is a predetermined number of times, for example, three or more, using the simultaneous correction relation DB 122. Therefore, the influence point analysis determination unit 113 can easily determine whether or not there is a simultaneous correction relationship.

(4) The influence point analysis / determination unit 113 outputs, for the influence element, the relevancy to the correction element as the correction influence type 1104. Therefore, it is possible to facilitate understanding of the relationship between the correction factor and the affected factor.

(5) The terminal device 100 includes an input unit 140 to which information specifying a correction element is input. The correction element identification unit (step S803 in FIG. 13) specifies a correction element based on the difference between the source code before and after the correction. Therefore, it is not necessary for the user to input the elements to be investigated one by one, and the elements to be investigated can be detected without omission.

(6) The terminal device 100 includes the simultaneous correction relation detection unit 112 that creates the simultaneous correction relation DB 122 based on the correction history of the source code and stores the same in the terminal storage unit 120.

(7) The influence output system 1 includes the terminal device 100 and the server 200. The terminal device 100 includes a terminal communication unit 150 that receives the source code correction history from the server 200, and an input / output processing unit 114 that causes the display unit 130 to display an influence output list 900 output by the influence point analysis determination unit 113. The server 200 includes a server storage unit 220 that stores a source code modification history, and a server communication unit 250 that transmits the source code modification history to the terminal device 100.

(8) The following program is stored in a ROM (not shown) of the terminal device 100. That is, the terminal storage unit stores the simultaneous correction relation DB 122 in which the correspondence of the elements simultaneously corrected based on the correction history of the source code of the program is recorded for the elements which are functions or variables described in the source code Allowing the terminal device 100 including 120 to identify a correction element which is an element to be investigated for the influence range by the correction (step S 803 in FIG. 13), and simultaneously affecting the elements affected by the correction of the correction element. The determination is made using the correction relation information (step S 807 in FIG. 13), and the result of the determination is output (step S 812 in FIG. 13).

The operation of the program may be changed as in the first to third modifications.
(Modification 1)
FIG. 15 is a diagram showing details of step S807 in FIG. 13 in the first modification. In other words, in the first modification, the CPU executes a program whose operation is represented by FIG. 15 instead of the program whose operation is represented by FIG. 14. The difference between FIG. 15 and FIG. 14 is that step S1203 in FIG. 14 is replaced with step S1203A in FIG.

  In step S1203A, the CPU determines whether the ratio between the number of corrections of the analysis target element and the number of simultaneous corrections counted in step S1202 is 75% or more. If it is determined that it is 75% or more, the process proceeds to step S1204. If it is determined that it is less than 75%, the process proceeds to step S1205.

According to the first modification, the following effects can be obtained.
(9) Using the simultaneous correction relationship DB 122, the influence point analysis determination unit 113 determines an element to be influenced based on a combination of elements in which the ratio of the number of simultaneous corrections to the total number of corrections is a predetermined ratio or more. Do. Therefore, even if the total number of corrections increases, it is not necessary to change the threshold each time.

(Modification 2)
FIG. 16 is a diagram showing details of step S 807 in FIG. 13 in the second modification. In other words, in the second modification, the CPU executes a program whose operation is represented by FIG. 16 instead of the program whose operation is represented by FIG. The difference between FIG. 16 and FIG. 14 is the processing when the negative determination is made in step S1203.

  In step S1211, which is executed when a negative determination is made in step S1203, the CPU determines whether the number of counts in step S1202 is two. If it is determined that the number of counts is 2, the process proceeds to step S1212, and if it is determined that the number of counts is other than 2, that is, 1 or zero, the process proceeds to step S1205. In step S1212, the CPU determines whether or not the simultaneous correction is within the last two revisions. If it is determined that it is within two revisions, the process proceeds to step S1204. If it is determined that it is not within two revisions, the process proceeds to step S1205. move on.

According to the second modification, the following effects can be obtained.
(10) The influence point analysis determination unit 113 uses the simultaneous correction relationship DB 122 to determine the relationship between the number of times of simultaneous correction and the threshold of the predetermined number, and the corrected time and the threshold of the predetermined time. Determine the affected elements based on a combination of For the most recently corrected part, it is possible to create an influence output list 900 in consideration of the corrected time, considering that there is a high possibility of including a potential defect.

(Modification 3)
FIG. 17 partially changes the operation of the flowchart of FIG. 13 in the first embodiment in the third modification. The processes up to step S809 and the processes after step S810 are the same as those of the first embodiment, and thus the description in FIG. 17 and the description of the operation thereof will be omitted. In step S851, which is executed when an affirmative determination is made in step S809, the number of stages of the call relationship between the analysis target element and the comparison target element and the number of stages of the simultaneous correction relationship are acquired. In the following step S852, it is determined whether or not the calling relationship is within three stages. If a positive determination is made, the process proceeds to step S853, and if a negative determination is made, the process proceeds to step S810. In step S853, it is determined whether the simultaneous correction relationship is within two stages. If the determination is affirmative, the process proceeds to step S811. If the determination is negative, the process proceeds to step S810. That is, when the calling relationship or the simultaneous correction relationship is equal to or more than the predetermined number of stages, no further analysis is performed.

According to the third modification, the following effects can be obtained.
(11) The influence point analysis determination unit 113 determines the influenced element based on the number of calling stages and the number of simultaneous correction stages for the correction element. In other words, when the number of calling stages and the number of simultaneous correction stages become equal to or more than the predetermined number of stages, the influenced point analysis / determination unit 113 interrupts the search for the influenced element. Therefore, the processing time can be shortened by preventing the analysis object from expanding endlessly. Further, since it is assumed that the more the number of stages is, the less related to the correction target element, it is possible to prevent the element which is less related to the correction target element from being described in the influence output list 900.

(Modification 4)
In the embodiment described above, the effect of the correction is output after the user corrects the source code. However, regardless of whether or not the source code has been modified by the user, elements that are affected when certain elements are modified may be output. In this case, instead of specifying the analysis target element by detecting the difference between the correction source code 124 and the registered source code 123, the correction difference detection unit 115 may use an element specified by the user as the analysis target element. . That is, in the first embodiment, the corrected element is referred to as a "correction element", but in the present variation, an object for examining the influence of the change is referred to as a "correction element".

  FIG. 18 is a diagram showing an example of the pre-modification influence check screen 951. As shown in FIG. The pre-modification influence check screen 951 includes a pre-modification input field 952, a survey target element input field 953, an analysis start button 954, and a list output field 955. The user invokes the pre-modification influence check screen 951, inputs the directory of the pre-modification source code in the pre-modification input field 952, and inputs the element to be investigated, for example, the element to be corrected from now on Do. This input determines the correction factor. Then, when the user presses the analysis start button 954, a list of elements that will be affected when the correction element is corrected is displayed in the list output field 905. According to the fourth modification, it is possible to investigate the influence before the user corrects the source code.

(Modification 5)
The simultaneous correction relationship detection unit 112 may process and save the simultaneous correction relationship DB 122 so as to be easy to use. FIG. 19 is a view showing an example of the simultaneous correction relation DB 122A obtained by processing the simultaneous correction relation DB 122. As shown in FIG. The simultaneous correction relationship DB 122A is composed of a plurality of records, and each record includes fields of function / variable 603, number of corrections 604, and number of simultaneous corrections 605. The fields of the function / variable 603 store elements included in the source code. The field of the function / variable 603 can be transferred to the leftmost column of the simultaneous correction relation DB 122 shown in FIG. The field of the number of corrections 604 stores the number of times the element stored in the field of the function / variable 603 has been corrected so far. The value of the field of the number of times of correction 604 is obtained by counting the number of circles in the simultaneous correction relation DB 122. In the field of the simultaneous correction number 605, the number of times of correction simultaneously with the element stored in the field of the function / variable 603 is stored for each element. The value of the field of the number of simultaneous corrections 605 is obtained by referring to the simultaneous correction relation DB 122 as in step S1202 of FIG. According to this modification, by using the simultaneous correction relationship DB 122A, it is possible to easily list the elements in the simultaneous correction relationship.

(Modification 6)
The terminal device 100 may not include the display unit 130 and the input unit 140. In this case, the input / output processing unit 114 outputs the video signal to the display device connected to the terminal device 100, and the input signal is input to the input / output processing unit 114 from the input device connected to the terminal device 100.

(Modification 7)
The format of the information stored in the simultaneous correction relationship DB 122 is not limited to the format shown in FIG. That is, as long as the information shown in FIG. 8 is included, it may be stored in any form.

(Modification 8)
The simultaneous modification relation detection unit 112 targets the source code of all the revisions stored in the configuration management DB 221, but may process only the source code corresponding to the specific condition. For example, only revisions generated in the last year may be processed, or only revisions after a specific version may be processed. Furthermore, only revisions with version numbers may be processed instead of comparisons between revisions. In addition to investigating the impact based on the latest source code, the impact may be investigated and output based on a specific revision in the past. For example, in order to investigate and output the influence of the element corrected in revision 50, call relation detection unit 111 constructs call relation DB 121 using the source code of revision 50, and simultaneous correction relation detection unit 112 carries out revision 49. The simultaneous correction relation DB 122 is constructed using the source code of up to the above, and the correction difference detection unit 115 detects a correction element from the difference between the source code of the revision 50 and the revision 49.

(Modification 9)
The modification influence type 1104 of the influence output list 900 may store more specific relevance. That is, all elements intervening between the correction factor and the influence factor may also be described along with the relationship. For example, although modifying FuncA affects FuncB, it is FuncC that has a concurrent modification relationship with FuncA and FuncB that has a recalled relationship with FuncC. -It may be described as "invoked".

(Modification 10)
The terminal device 100 does not include the call relation detection unit 111 and the call relation DB 121, and the call relation may not be evaluated. In this case, the influence output list 900 describes only the influence of the simultaneous correction relation.
