A difference installer generation unit (1200) generates a difference installer in which is included an applied difference selection program which compares the version of the software which has been installed in the user environment with the applied difference selection list and selects the difference which is acquired with the file update which is carried out in association with the software update which is carried out in the user environment.

Description

Information processing device, information processing method and information processing program product

The present invention relates to a method of updating a software.

Differential update is a method of software update. In the differential update, first, the old software and the new software are compared, and the changed content when the old software is updated to the new software is extracted as a difference. Then, a differential installer that applies the extracted difference to the legacy software is generated. Also, perform a differential installer on a computer with the old software installed, and update the old software to the new software.

In the differential update, the old software used for differential extraction and the old software that applies the difference must have the same file composition and contents of each file. When the file composition between the two old softwares or the contents of each file is different, it cannot be successfully updated to the new version, and sometimes the software cannot be executed.

To avoid this, the differential installer usually has the ability to verify that the version of the software installed on the computer matches the version of the legacy software used for differential extraction. This is based on the premise that if the software version is the same, the file composition and the contents of each file will be the same.

In the past update method, the differential installer confirmed the version of the software that was installed on the computer. Moreover, in the past update method, the differential installer selects the difference necessary to update the old software installed on the computer among the prepared plurality of differences, and applies the selected difference to the computer already installed. of Older software. The differential installer of the past update method updates the plural old version to the new version according to the above procedure (for example, Patent Document 1).

Advanced technical literature

Patent Document 1: Japanese Patent Laid-Open No. Hei 10-260820

In a large-scale software group, there is a file shared by a plurality of software references (hereinafter referred to as a shared file). Most of these shared files have backward compatibility even if they are updated. In this specification, the premise is that the shared file has backward compatibility.

When updating the software that uses the shared file in common, if the updated software uses the new function of the shared file, the shared file must also be updated at the same time.

In the case where the past differential update method is used to differentially update the shared file, the version information is added to the shared file, and the differential extraction is performed each time the shared file version is updated. Moreover, in order to generate this differential file differential update when generating a differential installer, it is necessary to specify which difference to apply to the shared file. This series of operations must be performed separately for each shared file, so as the number of shared files increases, the amount of work increases linearly. Therefore, it has been difficult in the past to differentially update software with a large number of shared files.

The main object of the present invention is to solve the above problems, and an object of the present invention is to efficiently perform file update of a shared file shared by a plurality of softwares.

The information processing apparatus of the present invention includes: an extracting portion, which is commonly used together When the file update of the shared file is accompanied by the software update of the shared file, the difference between the file and the file before the file update is extracted; the information generating unit analyzes the software of the complex software. Updating the relationship with the file update of the shared file, checking the difference obtained in the file update accompanying the execution of the software update executed in the user environment, and the version of the software installed in the user environment, thereby generating And the differential installer generating unit generates a differential installer including the selection program, and checks the version of the software installed in the user environment and the difference selection information, and selects the execution in the user environment. The difference obtained in the file update that is executed during the software update.

According to the present invention, the differential installer selects the difference obtained in the file update performed by the software update in response to the software installed in the user environment. Moreover, the differential installer performs the file update of the shared file of the difference selected by the application, so that the file update of the shared file can be efficiently executed.

Embodiment 1

Composition description

Fig. 1 is a view showing an example of the functional configuration of the differential mounter generating system 1000 of the present embodiment. In addition, the solid arrows in Fig. 1 indicate the call relationship, and the dotted arrows indicate the data operation.

The differential installer generation system 1000 is an example of an information processing device. In addition, the actions performed by the differential installer generation system 1000 are an example of an information processing method and an information processing program.

The differential mounter generation system 1000 is a computer having the hardware shown in Fig. 18. In addition, the hardware configuration shown in Fig. 18 will be described later.

The differential mounter generation system 1000 is composed of a differential extraction unit 1100, a differential installer generation unit 1200, an application difference selection list storage unit 1300, and a differential database 1400.

The difference extracting unit 1100 is composed of a software installer accepting unit 1101, a software group backup generating unit 1102, a software update executing unit 1103, a list generating unit 1104, a software group storage unit 1105, and a backup storage unit 1106. The list generation unit 1104 is an example of a extraction unit and an information generation unit. The operations performed by the list generating unit 1104 are examples of extraction processing and information generation processing.

Further, the differential installer generating unit 1200 is configured by a installer-generated content accepting unit 1201 and a differential installer generating executing unit 1202. The operation performed by the differential installer generating unit 1200 is an example of a differential installer generating process.

Action description

Next, the operation of the differential mounter generation system 1000 of the present embodiment will be described. example.

In the differential installer generation system 1000, processing for extracting the difference between the software and the difference of the shared file, and processing for generating the differential installer are performed. The processing of extracting the difference between the software and the difference of the shared file is performed by the difference extracting unit 1100. In addition, the process of generating the differential mounter is executed by the differential mounter generating section 1200.

Hereinafter, each process will be described with reference to a flowchart.

FIG. 2 is a flowchart showing an example of the operation of the difference extracting unit 110.

In step S101, the user specifies a complete installer including the software of the shared file in the software installer accepting unit 1101.

When the user updates the software included in the software group, the software installer accepting unit 1101 specifies the complete installer.

In this specification, a complex software that uses a shared file in common is called a software group. For example, in FIG. 3, the software 1, the software 2, and the software 3 use the shared file A and the shared file B in common. These software 1, software 2 and software 3 are software groups. In addition, the file 1 and the file 2 in Fig. 3 are files unique to the software 1. File 3 is a file inherent in Software 2. File 4 is a file inherent in software 3. These files that are not inherent in the software that are not shared among the software groups are called intrinsic files.

Next, in step S102, the software group backup generation unit 1102 generates a backup of the files included in the software group.

The soft group group is memorized in the soft group storage unit 1105. When the differential extraction processing to be described later is executed, the software update execution unit 1103 updates the soft body group of the soft group storage unit 1105. Therefore, the software group storage unit 1105 stores the software group (the updated software group) after the previous differential extraction processing.

In the subsequent program, in order to perform differential extraction processing before and after the update of the file included in the software group, it is necessary to have a file included in the software group before the update. Therefore, in step S102, the software group backup generation unit 1102 generates a backup of the software group and the files included in the software group. The software group backup generation unit 1102 stores the generated software group and file backup in the backup storage unit 1106.

In addition, the update of the software group is also called software update. Furthermore, the update of the file is also called file update. Software updates include both software version upgrades and new software installations. The file update also includes both the version upgrade of the file and the new installation of the file.

Next, in step S103, the software update execution unit 1103 updates the software group using the full installer.

The software update execution unit 1103 executes the software update of each software in the order of the software update preset in the user environment. The so-called user environment is the computer on which the software group is installed. The user environment and differential installer generation system 1000 are different computers.

Further, the software update execution unit 1103 updates the unique file of each software in association with the update of each software. Furthermore, the software update execution unit 1103 also updates the shared file with the update of any of the software groups.

As described above, the difference extracting unit 1100 manages the software update, the unique file update, and the update of the shared file. However, in the present embodiment, the update of the shared file is mainly described.

Then, in step S104, the list generation unit 1104 performs backup of the software group of the backup storage unit 1106 and differential extraction between the software groups after the update of the software group storage unit 1105.

The list generation unit 1104 performs differential extraction of software, differential extraction of unique files, and differential extraction of shared files.

In the difference extraction of the unique file and the differential extraction of the shared file, the list generating unit 1104 may determine whether or not the file is changed in units of the file, or may perform the comparison of the binary bits of the file and extract the difference of the binary unit.

FIG. 4 shows an example of a version migration list generated by the list generation unit 1104. In the version migration list, the migration of the software version and the migration of the version of the shared file are described. Fig. 4 shows a version migration list of software 1 to 3 (hereinafter also referred to as SW1 to 3) in which the shared file A and the shared file B are used in common.

In the field of "Installed Software", the identifier of the software that has been updated by the software update execution unit 1103 in the difference extracting unit 1100 is displayed.

The version of the updated software is displayed in the field of the "Software version".

The software update can be displayed by a combination of the value shown in the field of "Installed Software" and the value shown in the field of "Software Version". In the example of Fig. 4, the order of software update is sequentially described from the left. Specifically, in the example of Fig. 4, the version 1.0 of the newly installed software 1 is first installed, and then the version 1.0 of the software 2 is newly installed, and then the version 1.0 of the software 3 is newly installed. Software 1 is then updated to version 2.0, followed by software 2 updated to version 2.0. In addition, the combination of the value shown in the field of "Installed Software" and the value indicated by the field of "Software Version" (for example, the combination of "SW1" and "1.0") is called an update identifier.

In the field of the "version of the shared file", the version of the shared file that has been updated by the software update executing unit 1103 in the difference extracting unit 1100 is displayed. That is, in the field of "Version of Shared Files", the update process of the shared file stage is displayed. In the example of Fig. 4, the order of file update is sequentially described from the left. Specifically, In the example of Fig. 4, when the version 1.0 of the software 1 is installed, the version 1.0 of the shared file A and the version 1.0 of the shared file B are installed. Then, when version 1.0 of the software 2 is installed, the shared file A is updated to version 1.1, and the shared file B is updated to version 1.1. In addition, when version 1.0 of the software 3 is installed, only the shared file A is updated to version 1.2. In addition, when software 1 is updated to version 2.0, only the shared file B is updated to version 1.2. In addition, when the software 2 is updated to version 2.0, only the shared file A is updated to version 1.3.

If the difference of the shared file is applied in the order indicated by the field of the "Version file version" field, all versions of the shared file can be reproduced in the user environment.

Next, in step S105, the list generation unit 1104 stores the difference extracted in step S104 in the difference database 1400.

The configuration of the difference database 1400 is as shown in Fig. 5, for example. As shown in FIG. 5, the difference database 1400 manages the version information of the unique file, the version information of the shared file, and the difference information for each update identifier. In the version information of the intrinsic file, a combination of the old version name and the new version name of the intrinsic file is displayed. In the version information of the shared file, a combination of the old version name and the new version name of the shared file is displayed. In addition, in the difference information, the difference caused by the software update, the difference caused by the unique file update, and the difference caused by the shared file update are displayed.

As described above, the list generating unit 1104 generates an update identifier for each software update in steps S104 and S105, extracts the difference between the file and the shared file before the file update for the file of each shared file, and updates the file with the software. The updated update identifier corresponds to the extracted difference.

In addition, the file update of the intrinsic file is not performed during the software update. Next, the version information of the intrinsic file shows one version name of the intrinsic file. In addition, the difference of the unique file is not included in the difference information. Similarly, when the file update of the shared file is not performed in the software update, the version name of the shared file is displayed in the version information of the shared file. In addition, the difference information does not include the difference of the shared file.

Next, in step S106, the list generation unit 1104 generates an application difference selection list.

The so-called application differential selection list is a list for efficiently selecting the difference applied by the application differential selection program in the differential installer in the user environment. As will be described later, the file update of the shared file is performed in the user environment along with the software update. The application of the differential selection list is an application differential selection program in the differential installer that checks the difference between the file update performed in the execution of the software update in the user environment and the software version installed in the user environment. A list that can be selected. The list generation unit 1104 analyzes the relationship between the software update of the software group and the file update of the shared file, and updates the version of the shared file used by the updated version of the software being updated in the software update for each software update, thereby generating an application difference selection. List.

Apply a differential selection list as an example of differential selection information.

The details of the differential installer and the application differential selection program will be described later.

The application of the differential selection list is shown, for example, in FIG.

In Fig. 6, the fields of "Installed Software" and "Software Version" are the same as those shown in Figure 4. That is, in the application difference selection list, the update identifiers of the respective software updates are displayed in the order of the software update executed by the software update execution unit 1103.

In addition, the indicator information is information indicating an update identifier corresponding to the difference between the version of the shared file used in the updated version and the difference of the next version of the software indicated by the corresponding update identifier. In other words, when the software corresponding to the value of the index information is displayed in the user environment, the software for displaying the value of the index information is updated in one stage, in order to update the shared file of the value of the indicator information update. Which column of software to install, or apply the updated difference.

For example, assume that version 1.0 of software 1 is installed in the user environment, and the shared file A used by version 1.0 of this software 1 is version 1.0. The index information of the shared file A in the version 1.0 of the software 1 is "1". Therefore, the difference between the version 1.0 of the shared file A and the version 1.1 of the next version corresponds to the version 1.0 of the software 2 of the right column. In the application difference selection program in the difference installer, when the version 1 of the software 1 is installed in the user environment, the difference of the shared file A extracted when the software update execution unit 1103 installs the version 1.0 of the software 2 is applied to the shared version. Version 1.0 of file A, by which it is judged that version 1.1 of the shared file A can be obtained.

In addition, when the index information is 0, there is no difference in updating the shared file.

The generation of the application difference selection list of step S106 is based on the flowcharts shown in FIGS. 7 and 8. Details of Figures 7 and 8 will be described later.

Finally, in step S107, the list generation unit 1104 displays the application difference selection list on the display device, and the user confirms that the difference is correctly output.

Next, referring to Fig. 7 and Fig. 8, the generation procedure of applying the differential selection list will be described.

First, in step S301, the list generation unit 1104 adds a column to the right end of the application difference selection list, and describes the software and the version in the added column.

Next, in step S302, the list generation unit 1104 selects one shared file from the application difference selection list.

Then, the list generation unit 1104 refers to the version migration list in step S309, and determines whether or not the software version (hereinafter referred to as the determination target software) as the target version in step S301 includes the shared file selected in step S302 (whether or not it is used). Shared file).

If it is determined in step S309 that the target software does not include the shared file, the list generating unit 1104 specifies "-" in the index information of the shared file selected in step S302 added in step S301 in step S303.

Then, the list generating unit 1104 determines in step S310 whether all the shared files have been selected, and if there are still shared files that have not been selected, the next shared file is selected in step S308.

On the other hand, if the determination target software includes the shared file selected in step S302 in step S309, the list generating unit 1104 determines whether the shared file is referred to by referring to the version migration list in the update of the determination target software in step S311. Has been updated.

In step S311, when the shared file has been updated, the list generating unit 1104 specifies "0" in the index information of the shared file selected in step S302 added in step S301 in step S304.

Then, in step S305, if the index information of the shared files of the other columns is "0", the list generating unit 1104 updates the index information of the other columns to the column added in step S301.

On the other hand, in step S311, when the shared file is not updated, the list generating unit 1104 refers to the version migration list in step S306. The version of the shared file in the judgment object software.

Then, in step S307, the list generating unit 1104 specifies the amount of movement of the column of the software for which the difference of the next application is extracted, in the index information of the shared file of the column added in step S301.

Next, the operation of the differential mounter generating unit 1200 to generate the differential mounter will be described using the flowchart of FIG.

First, in step S201, the user specifies the information of the generated difference installer in the installer generation content accepting unit 1201.

The information specified by the user is the type of the software that generates the differential installer, the version before the update, and the version after the update.

The pre-update version is the oldest version of the version that the resulting differential installer can update. For example, when software version 1.0 exists in versions 1.0, 2.0, and 3.0, in the case of generating a differential installer that updates version 1.0 to version 3.0, the version before the update is 1.0, and the version after the update is version 3.0. At this time, the update from version 2.0 to version 3.0 can be performed by the generated differential installer.

Next, in step S202, the difference installer generation execution unit 1202 acquires the application difference selection list. The application difference selection list is stored in the application difference selection list storage unit 1300.

Here, the application difference selection list acquired by the difference installer generation execution unit 1202 must have a column corresponding to the software of the updated version. For example, in the application difference selection list of FIG. 6, the last added column is the column of version 2.0 corresponding to the software 2 of the right end, so the difference of the software developed after version 2.0 cannot be generated by the application differential selection list software 2. Installer.

Then, in step S203, the differential installer generates the execution unit 1202. Based on the information of the application difference selection list acquired in step S202, the difference necessary to generate the differential installer is selected.

The details of the operation of this step S203 will be described later with reference to Fig. 10.

Next, in step S204, the differential installer generation executing unit 1202 acquires the difference necessary for generating the differential installer from the differential database 1400.

That is, the difference installer generation executing unit 1202 acquires the difference information shown in FIG. 5 from the difference database 1400.

Next, in step S205, the differential installer generation executing unit 1202 generates a differential mounter.

The difference installer is composed of the application difference selection list acquired in step S202, the difference acquired in step S204, and the application difference selection program.

The application of the differential selection program uses the information of the version of the installed software in the user environment and the application of the differential selection list to apply the necessary differential programs in the appropriate order.

More specifically, the differential selection program is applied to extract an update identifier that is consistent with the pairing of the installed software and its version in the user environment from the complex update identifier shown in the application difference selection list. Further, the difference selection program is applied, and the difference corresponding to the update identifier indicated by the index information corresponding to the extracted update identifier is selected as the difference obtained in the file update performed in association with the software update executed in the user environment.

The differential selection program is used as an example of a selection program.

Further, an operation example in which the differential selection program is applied will be described later with reference to the flowcharts of Figs. 12 and 13.

Finally, the differential installer generation execution unit 1202 displays that the notification has been completed. As a message to generate the program for the differential installer, in step 206, the user confirms that the differential installer has been generated.

Next, with reference to Fig. 10, the operation of step S203 of Fig. 9 will be described, that is, the details of the operation for selecting the difference necessary for software update will be described.

First, in step S401, the difference installer generation execution unit 1202 specifies the version of the version before the update of the software that generates the difference installer from the application difference selection list. This column is referred to below as column A.

In step S402, the difference installer generation execution unit 1202 specifies the updated version of the software that generates the differential installer from the application difference selection list. This column is referred to below as column B.

Then, in step S403, the difference installer generates the execution unit 1202, and selects the software corresponding to the column (also referred to as the middle column) between the column A and the column B to be installed or updated to the corresponding software, and the column B. The difference between all the shared files extracted when the corresponding software is installed or updated to the corresponding software is taken as the necessary difference.

Finally, in step S404, the difference installer generation executing unit 1202 installs or updates the software corresponding to the column between the column A and the column B to the corresponding software, and installs or updates the software corresponding to the column B to the corresponding Among the differences extracted in the software, the difference between the inherent files of the software that generates the differential mounter is selected as the necessary difference.

Fig. 11 is a diagram showing an example in which the necessary difference is selected in order to generate a differential installer in which the version 1.0 of the software 1 is updated to the version 2.0 when the application difference selection list of Fig. 6 is used.

In the example in Figure 11, select the shared file when the version 2 of the software 2 is installed. The difference, the difference between the shared file at the time of installation of version 1.0 of the software 3, and the difference of the shared file when updating to the version 2.0 of the software 1. In addition, the difference of the unique file when updating to version 2.0 of the software 1 is selected.

Next, an example of the operation of applying the differential selection program will be described.

Applying the differential selection program, all candidate application differences are initially confirmed, and then applied to the shared file sequentially from the old difference. The differential selection program is used to confirm the candidate application difference for the row corresponding to each shared file in the application difference selection list. More specifically, the differential selection program is applied to determine the start and end points of each row of the differential selection list, and repeat the execution of the indicator information from the start point to the end point, and the index information is referred to as a new one. The starting point of the action. At this time, the difference corresponding to the column to which it passes is the candidate application difference.

More specifically, the differential selection program is applied in accordance with the flow shown in Figs. 12 and 13.

The operation of applying the differential selection program will be described below with reference to FIGS. 12 and 13.

First, in step S500, the differential selection program is applied to determine whether the differential installer is first applied to the user environment.

In the case where the differential installer is not used for the first time in the user environment, the application differential selection program acquires the differential information applied in the past in step S501.

Next, in step S502, the difference selection program is applied to obtain the software installed in the user environment and its version from the user environment.

Then, in step S514, the differential selection program is applied to determine Whether the software for the differential update version is installed in the user environment.

When the software for which the differential update version is not installed in the user environment, the difference selection program is applied to notify the user of the user environment of the fact that the differential update has failed in step S513.

Then, in step S503, the differential selection program is applied, and the column of the installed version and the updated version of the column in the user environment are confirmed in the application difference selection list, if the middle column and the updated version are in the column, If there is a difference column including the unique file of the software for differential mounting, the difference of the column is added to the candidate difference.

Next, in step S504, the differential selection program is applied to select a row of the shared file from the application difference selection list.

Next, in step S505, the difference selection program is applied, and the column of the starting point and the end point are specified from the row selected in step S504.

Next, in step S515, the differential selection program is applied to determine whether the starting point column is located to the left of all the end points.

In step 515, if the starting point is not located to the left of all the end points, the determination of step S517 is performed by applying the difference selection program.

On the other hand, if the starting point is located to the left of all the end points in step S515, in step S506, the differential selection program is applied to confirm the index information of the starting point in the row selected in step S504. Refers to the list.

Then, in step S507, the difference selection program is applied, and if the software update execution unit 1103 updates the software corresponding to the software indicated by the index information, the difference of the shared file is not included in the candidate application difference, and the difference is added. Candidate application difference.

Next, in step S516, the differential selection program is applied to determine whether the column indicated by the indicator information is the end point.

In step S516, if the index information indicates that the column is not the end point, the differential selection program is applied to designate the column indicated by the index information as the next starting point (step S508). Thereafter, the action after step S515 is repeatedly executed by applying the difference selection program.

On the other hand, if the index information is listed as the end point in step S516, the application difference selection program determines in step S517 whether or not the line of all the shared files in the application difference selection list has been confirmed. .

In step S517, if there is a line that has not been confirmed, the application difference selection program selects the unconfirmed shared file line from the application difference selection list in step S509.

On the other hand, in the case where the confirmation has been completed for all the lines of the shared file in step S517, the application difference selection program applies the candidate application difference sequentially to the shared file from the left side of the application difference selection list in step S510. And inherent files.

Then, in step S511, the differential selection program is applied to record the information of the applied difference in the memory area in the user environment.

Finally, in step S512, the differential selection program is applied to notify the user that the user's differential update has been completed.

Fig. 14 shows an example of the operation of applying the differential selection program.

In Fig. 14, the software having the application differential selection list of Fig. 6 is displayed in the user environment in which version 1.0 of the software 1 and version 1.0 of the software 2 are installed. An example of the operation of the differential selection program of the differential installer of 1. An example of applying the differential selection program to update the shared file A will be described below.

The version 1.0 of the software 1 of the software installed in the user environment and the version 1.0 of the software 2 are extracted by the differential selection program. In the example of Fig. 14, the column corresponding to the version 1.0 of the software 2 is applied as the starting point by the differential selection program (step S505). Further, the differential selection program is used to designate the column corresponding to the version 2.0 of the software 1 to be the software update target and the column of the version 1.0 of the software 3 as the end point (step S505).

Apply the differential selection program to confirm the index information in the starting point. In Fig. 14, since the index information is "1", the difference included in the difference installer corresponding to the version 1.0 of the software 3 is added to the candidate application difference (step S507).

Next, the differential selection program is applied, and the column indicated by the index information of the start point is designated as the next starting point (step S508). That is, the application of the differential selection program specifies the version 1.0 of the software 3 as the next starting point.

The starting point is located on the left side of the column corresponding to the version 1.0 of the software 3 as one of the end points, so the difference selection program is applied to end the differential selection for the shared file A.

As a result, in the software update execution unit 1103, the difference of the shared file A extracted when the version 1.0 of the software 3 is installed is used to update the shared file A that is executed when the version 2.0 of the software 1 is updated in the user environment. .

That is, the differential installer updates the version 2.0 of the software 1 and applies the difference to the shared file A existing in the user environment to update the file A in the near future.

Next, the details of the operation of the specified starting point and the end point of step S505 of Fig. 12 will be described with reference to the flowchart of Fig. 15.

First, in step S601, the application difference selection program extracts, from the application difference selection list, a column corresponding to the software installed in the user environment and a column corresponding to the difference applied in the past as a candidate starting point.

Next, in step S602, the differential selection program is applied to confirm the column indicated by the index information for each candidate starting point, and the column pointing to the rightmost column is designated as the starting point. In the case where there are a plurality of such columns, the differential selector is applied to specify the rightmost column in the application differential selection list as the starting point.

Next, in step S603, the differential selection program is applied to confirm the index information of the updated software.

Next, in step S607, the differential selection program is applied to determine whether the value of the index information is "-".

In step S607, if the value of the index information is "-", the application difference selection program designates the index information to all the columns on the left side of the updated software column as the end point in step S604.

On the other hand, if the value of the index information is not "-" in step S607, the application difference selection program determines in step S608 whether or not the index information is "0".

In step S608, if the value of the index information is "0", the application difference selection program designates all the columns whose index information is "0" as the end point in step S605.

In step S608, if the value of the index information is not "0", the differential selection program is applied, and in step S606, the updated software is listed. Set as the end point.

In addition, the differential selection program is used to designate the index information of the updated software column and the other columns indicated by the indicator information as the end points.

Fig. 16 and Fig. 17 show an example of the operation of obtaining the start point and the end point when the software 1 is updated to the version 2.0 in the user environment in which the version 1 of the software 1 and the version 1.0 of the software 2 are installed.

The column of version 1.0 of the software 1 and the column of version 1.0 of the software 2 are extracted by the difference selection program as a candidate start point column (step S601).

Further, the differential selection program is applied to confirm the index indicated by the index information of each candidate starting point column (step S602). The index information of version 1.0 of the software 2 is located on the right side of the index information of the version 1.0 of the software 1. Therefore, the differential selection program is used to designate the column of the version 1.0 of the software 2 as the shared file A and The starting point of the file B is shared (step S602).

Further, the difference information is used to confirm the index information of the version 2.0 of the software 1 (the updated software queue) (step S603).

For the shared file A, the index information of the version 2.0 of the software 1 is neither "-" nor "0." Therefore, the differential selection program is used to list the version 2.0 of the software 1 (the updated software column) and the index information to the version 1.0 of the software version 3.0 of the software version 2.0 (the indicator of the version 2.0 of the software 1) The information is referred to as the end point (step S606).

For the shared file B, the indicator information in the version 2.0 of the software 1 is "0". Therefore, the application of the difference selection program specifies that the version 2.0 of the software 1 in which the index information is "0" and the version 2.0 of the software 2 are listed as the end point (step S605).

As described above, apply a differential selection program to select columns from the application differential Among the plurality of update identifiers shown in the table, a column of the update identifier (first update identifier) matching the pair of software installed in the user environment and its version is extracted as a starting point. Further, by applying the difference selection program, a column of the update identifier (second update identifier) matching the pair of the software updated by the software update executed in the user environment and the updated version is extracted as the end point. Moreover, the differential selection program is applied, and the difference corresponding to the update identifier indicated by the index information corresponding to the start point column and the update identifier of the middle column between the start column and the end point in the application difference selection list are applied (intermediate update) The difference corresponding to the update identifier indicated by the indicator information corresponding to the identifier is the difference obtained in the file update performed in association with the execution of the software update executed in the user environment.

In addition, by applying the difference selection program, the update identifier indicated by the indicator information corresponding to the update identifier (intermediate update identifier) in the middle column of the application difference selection list is the update identifier (intermediate update identifier) or the end point of the other intermediate columns. When the update identifier (second update identifier) is updated, the difference between the update identifier (intermediate update identifier) of the other intermediate column or the update identifier (second update identifier) of the end point is selected as the software executed in the user environment. Update the difference obtained in the file update accompanying execution.

Description of the effect of the embodiment

As described above, in the present embodiment, the difference extracting unit 1100 has a soft body group of a plurality of softwares that use a shared file in common, and performs differential extraction while being updated by the installer. Therefore, it is possible to obtain the difference required to update the version by one order for all versions of the shared file.

Further, by applying the difference selection list and applying the difference selection program, the difference is sequentially applied to the shared file in the user environment, whereby the shared file can be updated when the software is updated.

Further, in the present embodiment, it is also possible to achieve the following effects. fruit.

Since the installer is input to the differential extracting unit, even if there are a plurality of shared files, it is not necessary to prepare a plurality of shared files having different versions for differential extraction.

Since the unit for performing differential extraction is the entire software group, even if there are a plurality of shared files, only one difference extraction is required for one update, and it is not necessary to perform differential extraction for each shared file.

The version of the shared file corresponds to the updated content by the installed installer. In addition, since the unique file of the software and the shared file are separately extracted and extracted, it is easy to manage the difference.

By applying the difference selection program, it is possible to select and update the difference of the shared file as long as it knows which software is updated or when the difference is applied. Therefore, there is no need to specify the version of the shared file updated within the differential installer.

The application differential selection program determines the difference of the application based on the information of the application differential selection list. Therefore, if the application differential selection list is updated, the application differential selection program can be used for any version of any software update.
