Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to an operating system upgrade method. Background Art

[0002] With the development of social science and technology, people deal with computers almost every day. As a carrier for computer equipment to interact with users, the operating system plays an extremely important role. Computer technology in contemporary society is in a stage of rapid development. In daily applications, in order to use the latest functions of applications in a timely manner, or to effectively defend against bad carriers such as Trojans, viruses, and junk software in a timely manner, it is often necessary to upgrade or update the operating system. Once the operating system is upgraded, the user's user data before the upgrade and the applications installed by the user should be guaranteed to be used normally.

[0003] In the existing system upgrade technology, one is to completely clear the data and applications in the old operating system to ensure that the applications in the upgraded or updated operating system will not conflict with the old version. The advantage of this solution is that it can ensure that the upgraded or updated operating system and applications can run normally and avoid the problem of mismatch between legacy data and applications. However, the user experience of this solution is poor, because after upgrading or updating the system, some of the user's previous convenient operations and marks are also cleared, and the user data and applications are completely deleted. The user needs to reconfigure the data and reinstall the required applications to adapt to the new system environment, which causes great inconvenience to the user. Another upgrade method uses a direct installation package method, and all user data and application data before the upgrade will be retained. The advantage of this solution is that all user data will not be lost, but it is only not lost, and the normal use of the application cannot be guaranteed. For example, if the version of the relevant library of the upgraded system is too high and inconsistent with the library version that the user's self-installed application depends on, it will cause the retained user application to be unavailable and the user experience is also poor. Summary of the invention

[0004] The purpose of the present invention is to provide an operating system upgrade method to solve the problem in the prior art that application programs cannot run normally after the system is upgraded.

[0019] Determine the type of the related file:

[0020] If it is a common file, the file is directly backed up to the custom file directory;

Technically, only one can be used, and it is impossible to use them at the same time. Feature E can be combined with feature C technically. Then, the solution of A+B+C+D should not be regarded as having been recorded because it is technically infeasible, and the solution of A+B+C+E should be regarded as having been recorded.

[0043] In the following description, many technical details are provided to help readers better understand the present application. However, those skilled in the art can understand that even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the claims of the present application can be implemented.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] refer to Figure 1 As shown, in one embodiment of the present application, a secure operating system upgrade method is disclosed. The operating system upgrade method described in this embodiment can be applied to computers that can run various types of operating systems, such as Linux operating system, XP operating system, VISTA operating system, WIN7 operating system, WIN8 operating system, WIN8.1 operating system and WIN10 operating system. The method includes:

[0046] In step 101, a location list of system data that needs to be retained before the upgrade is obtained. In one embodiment of the present application, the location list of data is confirmed based on the location defined by the standard data and the location of the dynamic data. For example, the traditional Linux operating system has a relatively clear location directory definition for user data, such as the user's home directory, etc. The configuration of dynamic data is pre-configured by overlaying the file system, and using the overlaid file system information storage method to obtain the location that does not belong to the traditional standard data definition, such as network configuration information under / etc / NetworkManager / , network connection data, and printing configuration data under / etc / cups, etc. The location information of the data list that needs to be retained is confirmed by combining the two.

[0047] In step 102, a list of applications installed by the user is obtained. In one embodiment, the list of applications installed by the user is obtained by diff, such as a picture viewer, QQ, WeChat, PDF reader, etc.

[0048] In step 103, the system data is backed up to a temporary area according to the data location.

[0049] In step 104, the application is backed up according to the application list.

[0050] Specifically, the step of backing up the application according to the application list includes:

[0051] First, back up the relevant files and library directories of each application to the corresponding custom directory. The custom directory corresponding to each application is created in the backup directory, for example, in the / opt directory. The custom directory includes a custom file directory and a custom library directory.

[0052] Next, the relevant files of each application are parsed, and the application link library is obtained by parsing, and the application link library is saved in the custom directory.

[0053] Among them, the step of parsing the relevant files of each application includes: analyzing the specific files installed to the system according to the software package of the target application, if it is a common file, directly backing up the file to the custom file directory; if it is a link file, copying the actual file corresponding to the link, and creating a corresponding link in the custom file directory; if it is an executable file ELF, backing up the link library displayed by ldd to the custom library directory, and generating a packaging script, exporting the link path of the custom library directory to LD_LIBRARY_PATH; modifying the Exec field value in the launcher file to point the executable program to the packaging script.

[0054] For example, taking the image viewer as an example, analyze the file list of this software package and save these file lists to the system reserved directory, where / usr / bin / eog is an executable file and the format is ELF, parse its dependent link library, back up the library file to the directory / opt / updateeog / eog, export the path to LD_LIBRARY_PATH, package the script file wrapper-eog, and modify the Exec field Exec=eog%U in the original launcher file to Exec=wrapper-eog%U.

[0055] Afterwards, parse the relevant files in the custom directory corresponding to each application and the postinst packaging script of the library directory. If a link file is created, extract the executable file corresponding to the application link library to generate a packaging script, which includes the executable file of the application and the file calling the system.

[0056] Clear the system basic library files in the backup library directory, such as libc library.

[0057] Extract the application package's postinst packaging script to the backup file directory.

[0058] In step 105, the system is upgraded, the system data is restored, and the configuration of each application is completed according to the backed-up data. All relevant files in the custom directory are overwritten into the system, and the postinst packaging script generated by the executable file is executed.
