Description

Information processing equipment and programs

This disclosure relates to technology for supporting software development.

In software development, it is rare that all source files are newly created, and in most cases, software development is performed by changing existing software.

If one source file is changed due to the dependency between multiple source files, the effect of the change may spread to other source files. In this case, it is necessary to change other source files according to the change of one source file.

The analysis of the ripple range of the above change effect is often performed manually, and if you are not a skilled software designer, there may be omissions or omissions in the identification of the ripple range, which may cause problems in the subsequent process.

Therefore, in the technique of Patent Document 1, attention is paid to the file modification time or check-in time, and the file having an indirect dependency relationship with the target file is specified.

Note that Patent Document 2 describes a file management technique, and Patent Document 3 describes a technique for obtaining a correlation between file events.

Embodiment 1.
FIG. 1 is a schematic diagram showing an example of the configuration of a software management system 500 including an information processing apparatus 100 according to the present embodiment. The software management system 500 (also simply referred to as a management system 500) is a system for managing software. The management system 500 includes, for example, a configuration management device 202 and an information processing device 100. Hereinafter, the software to be managed by the management system 500 may be referred to as the software to be managed.

The configuration management device 202 is a device that manages the configuration of the managed software. The configuration management device 202 is, for example, a kind of server device. It can be said that the configuration management device 202 is a computer device. The configuration management device 202 can manage, for example, versions of a plurality of source files 201 used in the development of managed software. It can be said that the configuration management device 202 includes a version control device that manages the version of the source file 201. As the version control device, the configuration management device 202 may be provided with, for example, a server device corresponding to Subversion (registered trademark) which is a kind of version control system, or may be provided with another type of device. The source file 201 is a file in which the source code is described in a programming language such as C language. Hereafter, the term "file" simply means a source file.

The configuration management device 202 includes, for example, a repository for storing each version of the file 201 used in the development of managed software. A repository is a kind of database. A terminal device is connected to the configuration management device 202. The terminal device can read the file 201 from the repository of the configuration management device 202 and write the file 201 in the repository. The terminal device can change the file 201 read from the repository according to the user's instruction. Then, the terminal device can write back the changed file 201 to the repository. Reading file 201 from the repository is called checkout. On the other hand, writing file 201 back to the repository is called check-in or commit. Hereinafter, the modified source file may be referred to as a modified source file or a modified file.

The configuration management device 202 can generate and output change history information 203 indicating the history of changes in the file 201 in each check-in unit, for example, with respect to the managed software. The change history information 203 is generated for each software development. FIG. 2 is a diagram showing an example of change history information 203.

As shown in FIG. 2, the change history information 203 includes a revision ID (identifier). The revision ID corresponds to check-in. The revision ID is, for example, a number that starts with the number 1 and is incremented by 1 for each check-in. The revision ID is also called the revision number. In the change history information 203, information for identifying the change file 201 written back to the repository at the check-in corresponding to the revision ID is associated with each revision ID, for example. As the information, for example, a file name is adopted. In the change history information 203, the maximum revision ID corresponds to the latest check-in. The change history information 203 is also referred to as a revision log.

In the example of FIG. 2, the file names of the modified source files A, B, C, and D written back to the repository at the check-in corresponding to revision 1 are associated with revision 1. The change source files A, B, C, and D corresponding to revision 1 are checked in all at once. Further, the file name of the change source file C written back to the repository at the latest check-in is associated with the maximum revision 12.

The information processing device 100 identifies a plurality of files 201 that are likely to be changed and collectively checked in, including the target file 201 of interest, based on the change history information 203 output by the configuration management device 202. .. As the target file, for example, the file 201 related to the latest check-in is adopted. When the file 201 related to the latest check-in, in other words, the file 201 written back to the repository in the latest check-in is the file C, the information processing apparatus 100 is changed and collectively checked in including the file C. Identify multiple files 201 that are likely to be.

Here, consider, for example, a case where the influence of the change of the file A spreads to the files B and C due to the dependency between the files A, B, and C. In this case, the files B and C are also changed according to the change of the file A, and there is a high possibility that the changed files A, B, and C are checked in all at once. Therefore, in a plurality of files 201 that are likely to be checked in all at once, including the target file 201, the files 201 other than the target file 201 are likely to be affected by the change of the target file 201. It can be said that. Therefore, it is possible to identify the file 201 that is likely to be affected by the change of the target file 201 from the plurality of files 201 that are likely to be checked in all at once, including the target file 201.

The information processing device 100 includes a generation unit 110 and a specific unit 120. The generation unit 110 includes a first generation unit 111 and a second generation unit 112. The first generation unit 111 generates list information 190 indicating a list of change file sets including a plurality of change files 201 collectively checked in based on the change history information 203. In addition, the first generation unit 111 generates the latest check-in information 160 for identifying the file 201 related to the latest check-in, that is, the change file 201 written back to the repository in the latest check-in. The latest check-in information 160 includes, for example, the file name of the change file 201 written back to the repository at the latest check-in. For example, when the changed files A to C are written back to the repository in the latest check-in, the latest check-in information 160 includes the respective file names of the files A to C.

The second generation unit 112 provides frequency information 150 indicating the frequency with which the plurality of files 201 constituting the combination are changed and checked in collectively for each combination of the plurality of files 201, based on the list information 190. Generate.

<About the first generation unit>
FIG. 4 is a diagram showing an example of the list information 190 generated by the first generation unit 111. The list information 190 shown in FIG. 4 is information generated based on the change history information 203 shown in FIG. In the list information 190, specific information 191 for specifying a change file set consisting of a plurality of change files 201 checked in collectively is listed for each check-in. As the specific information 191, for example, the file names of a plurality of files 201 constituting the modified file set are adopted.

The first generation unit 111 determines whether or not a plurality of file names are associated with each revision ID of the change history information 203. Then, the first generation unit 111 registers the plurality of file names associated with one revision ID in the list information 190 as the file names of the plurality of files 201 constituting one change file set.

In the example of FIG. 2, a plurality of file names are associated with each of revisions 1 to 5, 7 to 10. The first generation unit 111 registers a plurality of file names associated with revisions 1 to 5, 7 to 10 in the list information 190 in units of revision IDs. Hereinafter, the file names of a plurality of files 201 constituting the changed file set may be referred to as a file name group.

In the example of FIG. 4, the file names of files A, B, C, and D shown in the top list of the list information 190 correspond to revision 1. The file names of files A and E shown in the second list from the top of the list information 190 correspond to revision 2. The file names of files B and C shown in the last list of list information 190 correspond to revision 10. By referring to the list information 190, a plurality of change files 201 that have been collectively checked in can be specified for each check-in.

FIG. 5 is a flowchart showing an example of a process (also referred to as a first generation process) in which the first generation unit 111 generates the list information 190 and the latest check-in information 160. As shown in FIG. 5, in step s31, the first generation unit 11 substitutes 1 for the variable n. Then, in step s32, the first generation unit 11 determines whether or not the revision n is included in the change history information 203. If No is determined in step s32, the first generation process ends. On the other hand, if Yes is determined in step s32, step s33 is executed. In step s33, the first generation unit 111 registers the file name associated with the revision n in the latest check-in information 160.

Next, in step s34, the first generation unit 111 determines whether or not a plurality of file names are associated with the revision n. If No is determined in step s34, step s36 is executed. On the other hand, if Yes is determined in step s34, step s35 is executed.

In step s35, the first generation unit 111 registers a plurality of file names associated with the revision n in the list information 190 as a file name group. After that, step s36 is executed. In step s36, the first generation unit 111 adds 1 to the variable n.

After step s36, step s32 is executed again, and then the first generation unit 111 operates in the same manner. In the second and subsequent steps s33, the file name already registered in the latest check-in information 160 is replaced with the file name associated with the revision n.

In step s36, the value of the variable n becomes the maximum revision ID, and in the next step s36, if the value of the variable n becomes larger than the maximum revision ID by one, it is determined as No in the immediately following step s32. .. As a result, the first generation process is completed, and the list information 190 and the latest check-in information 160 are completed. The completed latest check-in information 160 contains the file name associated with the largest revision ID. The file name associated with the highest revision ID is the file name of the change file 201 that was written back to the repository at the latest check-in.

<About the second generator>
FIG. 6 is a diagram showing an example of frequency information 150 generated by the second generation unit 112. The frequency information 150 shown in FIG. 6 is information generated based on the list information 190 shown in FIG. The frequency information 150 includes, for each combination of the plurality of files 201, the frequency with which the plurality of files 201 constituting the combination are changed and checked in collectively.

In the frequency information 150, a plurality of combinations for the file 201 are registered. Specifically, in the frequency information 150, the combination specifying information 151 for specifying the combination is registered for each combination of the file 201. In the frequency information 150, a plurality of combination specific information 151 are arranged in order. As the combination specific information 151, for example, the file names of a plurality of files 201 constituting the combination are adopted. In the frequency information 150, the frequency (in other words, the number of times) in which a plurality of files 201 constituting the combination specified by the combination specific information 151 are changed and checked in collectively is associated with each combination specific information 151. ing.

The second generation unit 112 extracts, for example, all the file names included in the list information 190. Next, the second generation unit 112 obtains all combinations for the plurality of files 201 having each of the extracted plurality of file names. Then, the second generation unit 112 registers each obtained combination and the corresponding frequency in the frequency information 150. That is, the second generation unit 112 registers the combination identification information 151 for specifying the combination and the frequency corresponding to the combination in the frequency information 150 for each obtained combination.

In the example of FIG. 4, the list information 190 includes the file names of the files A to E. Therefore, the frequency information 150 includes a plurality of combination specific information 151 as shown in FIG.

Here, for example, consider a combination of files B and D. In the example of FIG. 4, there are four modified file sets including files B and D. Therefore, in the example of FIG. 4, the frequency of changing the files B and D and checking in all at once is four times. Therefore, in the example of FIG. 6, the frequency “4” is associated with the combination specifying information 151 for specifying the combination of the files B and D.

As another example, consider a combination of files B, C, and D. In the example of FIG. 4, there are three modified file sets including files B, C, and D. Therefore, in the example of FIG. 4, the frequencies of files B, C, and D being changed and checked in all at once are three times. Therefore, in the example of FIG. 6, the frequency “3” is associated with the combination specification information 151 for specifying the combination of the files B, C, and D.

FIG. 7 is a flowchart showing an example of a process (also referred to as a second generation process) in which the second generation unit 112 generates the frequency information 150. As shown in FIG. 7, in step s41, the second generation unit 112 obtains a plurality of combinations for the file 201. For example, the second generation unit 112 extracts all the file names included in the list information 190. Then, the second generation unit 112 obtains all combinations for the plurality of files 201 having the extracted plurality of file names.

Next, in step s42, the second generation unit 112 registers the combination specific information 151 of each obtained combination in the frequency information 150. Then, in step s43, the second generation unit 112 sets a plurality of file names included in the first list of the list information 190 in the variable i.

Next, in step s44, the second generation unit 112 determines whether or not the variable i is empty. If Yes is determined in step s44, the second generation process ends. On the other hand, if No is determined in step s44, step s45 is executed.

In step s45, the second generation unit 112 has a plurality of files at least a part of the plurality of files 201 each having a plurality of file names set in the variable i among the plurality of combinations registered in the frequency information 150. All combinations including 201 (also referred to as first specific combination) are specified. The second generation unit 112 adds 1 to the frequency corresponding to the combination specific information 191 of the first specific combination in the frequency information 150.

In the example of FIG. 4, since the first list of the list information 190 includes the file names of the files A to D, the file names of the files A to D are set in the variable i. In this case, in the example of FIG. 6, the combination of files A and B, the combination of files A and C, the combination of files A and D, the combination of files B and C, the combination of files B and D, and the combination of files C and D. , A combination of files A, B, C, a combination of files A, B, D, a combination of files B, C, D, and a combination of files A to D, each of which is the first specific combination. Then, 1 is added to the frequency corresponding to the combination specific information 191 of these first specific combinations.

After step s45, in step s46, the second generation unit 112 sets a plurality of file names included in the next list of the list information 190 in the variable i. After that, step s44 is executed again, and thereafter, the second generation unit 112 operates in the same manner. In step s46, when a plurality of file names included in the last list of list information 190 are set in the variable i, in the next step s46, there are no plurality of file names to be set in the variable i. Therefore, in step s44 immediately after that, Yes is determined and the second generation process ends.

After that, step s52 is executed again, and thereafter, the specific unit 120 operates in the same manner. In step s56, when a plurality of file names constituting the final combination specific information 151 of the frequency information 150 are set in the variable j, in the next step s56, there are no plurality of file names to be set in the variable j. .. Therefore, in step s52 immediately after that, it is determined as Yes, and the third generation process ends.

The specific information 170 generated as described above is notified to, for example, the user of the information processing apparatus 100. The information processing device 100 notifies the user of the specific information 170 by displaying the specific information 170 generated by the specific unit 120 on, for example, the display device 5. By referring to the specific information 170, the user can identify the file 201 that is likely to be affected by the change in the target file 201. When the target file 201 is the file 201 related to the latest check-in, the user may identify the file 201 that is likely to be affected by the recently changed file 201 by referring to the specific information 170. can. In other words, by referring to the specific information 170, the user can identify the file 201 that is likely to be changed in response to the change of the recently changed file 201.

Here, as described above, in a plurality of files 201 that are likely to be checked in all at once, including the target file 201, the files 201 other than the target file 201 are affected by the change of the target file 201. It can be said that the file 201 has a high possibility. Of the plurality of file names included in the specific information 170, the user sets the file 201 having a file name other than the file name of the target file 201 as the file 201 that is likely to be affected by the change of the target file 201. .. Then, the user determines whether or not the specified file 201 needs to be changed, and if it is determined that the specified file 201 needs to be changed, the user changes the specified file 201. This makes it difficult for omissions / omissions of changes in the file 201 to occur.

For example, consider the case where the file 201 related to the latest check-in is only the file C as in the example of FIG. In this case, the user changes the file B and D having a file name other than the file name of the file C among the file names of the files B, C, and D included in the specific information 170 shown in FIG. It is assumed that the file 201 is likely to be affected by the above. Then, the user determines whether or not each of the files B and D needs to be changed, and if it is determined that the change is necessary, the user changes the corresponding file 201.

As another example, consider the case where the file 201 related to the latest check-in is files B and D. In this case, the user sets the file C having a file name other than the file names of the files B and D among the file names of the files B, C, and D included in the specific information 170 shown in FIG. 9 to the files B and D. It is assumed that the file 201 is likely to be affected by the change of. Then, the user determines whether or not the file C needs to be changed, and if it determines that the file C needs to be changed, the user changes the file C.

Note that the information processing apparatus 100 does not have to notify the user of the file name of the target file 201 among the plurality of file names included in the specific information 170. In this case, for example, the display device 5 does not have to display the file name of the target file 201 among the plurality of file names included in the specific information 170. Further, the method in which the information processing apparatus 100 notifies the user of the file name included in the specific information 170 is not limited to the above example. The information processing apparatus 100 may notify the user of the file name included in the specific information 170 by using, for example, voice. Further, the information processing apparatus 100 may transmit the specific information 170 to another apparatus. The information processing apparatus 100 may transmit the specific information 170 to the configuration management apparatus 202 or may transmit it to another apparatus.

The first generation process, the second generation process, and the third generation process as described above may be executed, for example, each time a check-in occurs. FIG. 11 is a flowchart showing an example of the operation of the management system 500 in this case. When the configuration management device 202 detects the occurrence of a new check-in in step s1, the configuration management device 202 updates the change history information 203 in response to the occurrence of a new check-in in step s2. Specifically, the configuration management device 202 registers the new revision ID and the file name of the change file 201 written back to the repository at the new check-in in association with the change history information 203. The updated change history information 203 is input to the information processing apparatus 100.

After step s2, in step s3, the first generation unit 111 of the information processing apparatus 100 executes the first generation process using the updated change history information 203. That is, the first generation unit 111 newly generates the list information 190 and the latest check-in information 160 based on the updated change history information 203. The first generation unit 111 generates the list information 190 and the latest check-in information 160 in response to the occurrence of the latest check-in.

Next, in step s4, the second generation unit 112 executes the second generation process using the list information 190 generated in step s3. That is, the second generation unit 112 newly generates the frequency information 150 based on the list information 190 generated in step s3. The second generation unit 112 generates frequency information 150 according to the occurrence of the latest check-in.

Next, in step s5, the specific unit 120 includes the frequency information 150 generated in step s4 (in other words, the frequency information 150 generated in response to the occurrence of the latest check-in) and the latest check-in generated in step s3. The third generation process using the information 160 is executed. That is, the specific unit 120 generates the specific information 170 based on the frequency information 150 generated in step s4 and the latest check-in information 160 generated in step s3.

After step s5, when the configuration management device 202 detects the occurrence of a new check-in (step s1), step s2 is executed again, and thereafter, the management system 500 operates in the same manner.

As described above, in the present embodiment, based on the change history information 203 indicating the history of changes in the file 201 in the check-in unit, the changes are collectively checked in including at least one target file 201. Multiple files 201 that are likely to be identified are identified. In a plurality of files 201 that are likely to be checked in all at once, including the target file 201, the files 201 other than the target file 201 are the files 201 that are likely to be affected by the change of the target file 201. It can be said that. Therefore, it is possible to identify the file 201 that is likely to be affected by the change of the target file 201 from the plurality of files 201 that are likely to be checked in all at once, including the target file 201. This makes it difficult for omissions / omissions of changes in the file 201 to occur. As a result, the quality of managed software can be improved.

Further, in the present embodiment, a plurality of files 201 that are likely to be changed and checked in all at once, including the target file 201, that is, a specific file set is specified for each combination of the plurality of files 201. , Frequency information indicating the frequency with which a plurality of files 201 constituting the combination are changed and checked in all at once is used. This makes it possible to specify a specific file set with higher accuracy.

Further, in the present embodiment, based on the frequency information 150 generated in response to the occurrence of the target check-in of interest (the latest check-in in the above example), the file 201 related to the target check-in is included and changed in a batch. A plurality of files 201 that are likely to be checked in have been identified. As a result, a plurality of files 201 that are likely to be changed and collectively checked in, including the file 201 related to the target check-in, are identified based on the frequency information 150 in which the information regarding the target check-in is reflected. File. Therefore, the specific file set can be specified more accurately.

Embodiment 2.
In the first embodiment described above, frequency information 150 and specific information 170 are generated according to the occurrence of check-in. On the other hand, in the present embodiment, the generation of the frequency information 150 and the generation of the specific information 170 are performed independently. FIG. 12 is a schematic diagram showing an example of the configuration of the software management system 500A including the information processing apparatus 100A according to the present embodiment.

The software management system 500A (also referred to as a management system 500A) includes a configuration management device 202A and an information processing device 100A. The configuration management device 202A generates and outputs the latest check-in information 204 in addition to the change history information 203 in the above-mentioned configuration management device 202. The latest check-in information 204 is information for identifying the change file 201 related to the latest check-in. That is, the latest check-in information 204 is information for identifying the change file 201 written back to the repository in the latest check-in.

FIG. 13 is a diagram showing an example of the latest check-in information 204. As shown in FIG. 13, the latest check-in information 204 includes a revision ID corresponding to the latest check-in and specific information 2040 for identifying the change file 201 related to the latest check-in. The specific information 2040 is, for example, the file name of the change file 201 related to the latest check-in. In the example of FIG. 13, the latest check-in information 204 includes the revision 13 corresponding to the latest check-in and the file name of the file C related to the latest check-in.

The information processing apparatus 100A includes a generation unit 110A and the above-mentioned specific unit 120. The generation unit 110A includes a first generation unit 111A and the above-mentioned second generation unit 112. The first generation unit 111A does not generate the latest check-in information 160 in the above-mentioned first generation unit 111. The first generation unit 111A does not execute step s33 in the above-mentioned first generation process.

FIG. 14 is a flowchart showing an example of the operation of the generation unit 110A. The generation unit 110A repeatedly executes a series of processes shown in FIG. The generation unit 110A executes a series of processes shown in FIG. 14, for example, at regular time intervals.

As shown in FIG. 14, in step s111, the first generation unit 111A of the generation unit 110A acquires the change history information 203. In step s111, the first generation unit 111A generates, for example, transmission request information indicating a transmission request of the change history information 203. This transmission request information is transmitted from the communication device 4 of the information processing device 100A to the configuration management device 202A. Upon receiving the transmission request information, the configuration management device 202A transmits the latest change history information 203 to the information processing device 100A. In the information processing device 100A, the communication device 4 receives the change history information 203. The received change history information 203 is input to the first generation unit 111A. As a result, the first generation unit 111A acquires the change history information 203 in step s111.

Note that the configuration management device 202A may transmit the change history information 203 to the information processing device 100 each time a new check-in occurs, as shown in FIG. 11 above. In this case, the information processing device 100A stores, for example, the received change history information 203 in the storage device 2. Then, when the information processing apparatus 100A receives the new change history information 203, the information processing apparatus 100A replaces the change history information 203 in the storage device 2 with the received new change history information 203. The first generation unit 111A reads and acquires the change history information 203 from the storage device 2 at the execution timing of step s111.

After step s111, in step s112, the first generation unit 111A generates the list information 190 based on the change history information 203 acquired in step s111. Next, in step s113, the second generation unit 112 generates frequency information 150 based on the list information 190 generated in step s112. Then, the second generation unit 112 stores the generated frequency information 150 in the storage device 2. When the second generation unit 112 newly generates the frequency information 150, the second generation unit 112 replaces the frequency information 150 in the storage device 2 with the generated frequency information 150.

FIG. 15 is a flowchart showing an example of the operation of the specific unit 120. As shown in FIG. 15, in step s121, the specific unit 120 acquires the latest check-in information 204. For example, the configuration management device 202A generates the latest check-in information 204 every time a new check-in occurs and transmits the latest check-in information 204 to the information processing device 100A. The latest check-in information 204 input to the information processing apparatus 100A is input to the specific unit 120. The specific unit 120 executes step s121 every time a new check-in occurs to acquire the latest check-in information 204.

After step s121, in step s122, the specific unit 120 reads out the frequency information 150 from the storage device 2 and acquires it. Then, in step s123, the specific unit 120 generates specific information 170 based on the frequency information 150 acquired in step s122 and the latest check-in information 204 acquired in step s121. The specific unit 120 uses the latest check-in information 204 instead of the latest check-in information 160 in the third generation process described above. When a new check-in occurs after step s123, steps s121 to s123 are executed.

As described above, in the present embodiment, the plurality of files 201 that are likely to be changed and collectively checked in, including the file 201 related to the target check-in of interest (the latest check-in in the above example). For specific purposes, frequency information 150 generated prior to the occurrence of the target check-in is used. As a result, as compared with the case where the frequency information 150 is generated according to the occurrence of the target check-in as in the first embodiment, the specific unit 120 immediately generates the frequency information 150 when the target check-in occurs. Can be obtained. Therefore, the specific unit 120 can immediately specify the specific file set including the file 201 related to the target check-in when the target check-in occurs.

In the first embodiment described above, when the configuration management device 202 generates the latest check-in information 204, the specific unit 120 uses the latest check-in information 204 generated by the configuration management device 202 to generate the specific information 170. May be generated. In this case, the first generation unit 111 does not have to generate the latest check-in information 160.

In the

above embodiments

1 and 2, the file name is used as the information for specifying the file 201, but other information may be used. As the information for identifying the file 201, for example, the identification number of the file 201 may be used. In this case, the list information 190 and the like include the identification number of the file 201 instead of the file name.

Further, in the first and second embodiments, the frequency information 150 includes the frequency (in other words, the number of times) itself, but may include information indirectly indicating the frequency. For example, it may contain information indicating the degree of frequency, such as high frequency, medium frequency, and low frequency. In this case, in step s54 of the third generation process described above, it may be determined whether or not the information including the frequency information 150 indicating the degree of frequency corresponding to the processing target combination indicates "high frequency". ..

Further, in the first and second embodiments, the specific information 170 is information for identifying a plurality of files 201 that are likely to be changed and collectively checked in, including at least one target file 201. However, even if it is information for identifying a file 201 other than the target file 201 among a plurality of files 201 that are likely to be changed and checked in all at once, including at least one target file 201. good. That is, the specific information 170 may be information for identifying the file 201 in which the change of the target file is likely to spread. In this case, the specific information 170 includes information for specifying a file 201 other than the target file 201 among the plurality of files 201 constituting the specific file set, instead of the specific file set information 171.
