Description

Upgrade method and upgrade system of operating system

Technical Field

The present invention relates to the field of computer technologies, and in particular, to an upgrade method of an operating system.

Background

With the development of social technology, people almost every day can make a way with a computer, and an operating system is used as a carrier for interaction between computer equipment and users and plays an extremely important role. In the current society, computer technology is in a high-speed development stage, and in daily application, in order to timely use the latest functions of application programs or timely defend bad carriers such as Trojan horse, virus, garbage software and the like, version upgrading or updating of an operating system is often required. Once the operating system is upgraded, the user data before the upgrade and the application program installed by the user should be guaranteed to be used normally.

In the existing system upgrading technology, a scheme of thoroughly clearing data and applications in an old operating system is adopted, so that the applications in the upgraded or updated operating system cannot conflict with the old version. The proposal has the advantages of ensuring that the upgraded or updated operating system and application can normally run, and avoiding the problem of unmatched legacy data and application. However, the user experience of this scheme is poor, because after upgrading or updating the system, some convenient operations and marks before the user are also cleared, the user data application program is completely deleted, the user needs to reconfigure data and reinstall the required application program, and the new system environment is readjusted, which causes great inconvenience to the user. The other upgrading mode adopts a direct package installation mode, all user data and application data before upgrading are reserved, and the scheme has the advantages that all data of a user cannot be lost, but only cannot be lost, and normal use of an application program cannot be guaranteed. For example, if the related library version of the updated system is too high, and is inconsistent with the library version on which the user self-installed application program depends, the retained user application program is not available, and the user experience is poor.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be understood by those skilled in the art that the claimed application may be practiced without these specific details and with various changes and modifications from the embodiments that follow.

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, in one embodiment of the present application, a secure upgrade method for an operating system is disclosed, and the upgrade method for an operating system described in this embodiment may be applied to a computer capable of running multiple types of operating systems, such as a Linux operating system, an XP operating system, a VISTA operating system, a WIN7 operating system, a WIN8 operating system, a WIN8.1 operating system, a WIN10 operating system, and the like. The method comprises the following steps:

In step 101, a location list of system data to be maintained before upgrade is obtained. In one embodiment of the application, a list of locations of data is validated based on locations defined by standard data and dynamic data locations. For example, the conventional Linux operating system has a relatively clear location directory definition for user data, such as a home directory of a user, and the configuration of dynamic data is performed in advance by a file system superposition mode, and the location information of a data list to be reserved is confirmed by combining the two, wherein the location information is located at a location which is not attributed to the conventional standard data definition, such as network configuration information under/etc/NetworkManager/network connection data, print configuration data under/etc/caps, and the like, by using a file system information storage mode after superposition.

In step 102, a list of applications installed by a user is obtained. In one embodiment, the user's application manifest is obtained by diff means, such as a picture viewer, QQ, weChat, PDF reader, etc.

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

In step 104, the application program is backed up according to the application program list.

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

firstly, relevant files and library catalogs of each application program are backed up to corresponding custom catalogs, the custom catalogs corresponding to each application program are created under the backup catalogs, for example, under the/opt catalogs, and the custom catalogs comprise custom file catalogs and custom library catalogs.

And then, analyzing relevant files of each application program, analyzing and obtaining an application program link library, and storing the application program link library into the custom directory.

The method comprises the steps of analyzing specific files installed to a system according to a software package of a target application program, directly backing up the files under a custom file directory if the files are common files, copying actual files corresponding to links and creating corresponding links under the custom file directory if the files are link files, backing up a link LIBRARY displayed by ldd to the custom LIBRARY directory if the files are executable files ELF, generating a package script, deriving a link PATH of the custom LIBRARY directory to LD_LIBRARY_PATH, modifying an Exec field value in a starter file, and pointing an executable program to the package script.

For example, taking a picture viewer as an example, analyze the file lists of this software package, save these file lists to a system-reserved directory, where/usr/bin/eog is an executable file and is formatted as an ELF, parse its dependency link LIBRARY, backup the LIBRARY file to directory/opt/updateeog/eog, export the PATH to ld_libry_path, encapsulate script file wrapper-eog, and modify Exec field exec= eog% U in the original initiator file to exec=wrapper-eog% U.

And then, analyzing the related files in the custom catalogs corresponding to the application programs and postinst encapsulation scripts of the library catalogs, and if a link file is created, extracting the executable files corresponding to the application program link library to generate the encapsulation scripts, wherein the encapsulation scripts comprise the executable files of the application programs and the files of the calling system.

And clearing system base library files in the backup library catalogue, such as libc libraries and the like.

Postinst package scripts of the application software package are extracted into the backup file directory.

In step 105, system upgrade is performed, the system data is recovered, and the configuration of each application program is completed according to the backed-up data. And overlaying all relevant files under the custom directory into a system, and executing postinst encapsulation scripts generated by the executable files.

Referring to fig. 2, the application also discloses an upgrade system of an operating system, which comprises:

A location list obtaining module 201 configured to obtain a location list of system data to be retained before upgrading;

An application manifest acquisition module 202 configured to acquire a user-installed application manifest;
