Method simultaneously supporting two software package managers and supporting software package interdependence and conflict detection

Abstract

The invention relates to a method simultaneously supporting two software package managers and supporting software package interdependence and conflict detection, which comprises the following steps of: establishing a unified database, and storing rpm software package information and deb software package information; creating a unified processing dynamic library to operate the unified database, andpackaging the operation of processing the information associated with rpm and dpkg into an interface to be called by an external program; transforming rpm and dpkg, changing the original operation ofrpm and dpkg on respective databases into the operation of calling a unified database interface to operate the unified database, and recording software package information into the unified database;modifying a packaging tool, and changing the original operation on respective databases in the packaging process into calling a unified database interface to operate the unified database; modifying yum and apt, and changing the original operation of a network packet manager on respective databases into the operation of calling the unified database interface to operate the unified database; and making an initialization tool, wherein the initialization tool is used for importing database information of the original software package manager of the system into the unified database.

Description

technical field [0001] The invention relates to the technical field of computer software package compatibility, in particular to a method for simultaneously supporting two software package managers and supporting software package interdependence and conflict detection. Background technique [0002] Among the distributions of the Linux operating system, there are two relatively mainstream distributions, namely the redhat-based distribution represented by centos, and the debian-based distribution represented by ubuntu. Among them, the redhat-based distribution uses rpm as the package manager to install, uninstall, update, and query rpm-format software packages; the debian-based distribution uses dpkg as the package manager to manage deb-format software packages. [0003] The usage habits of users such as the command format, output format and packaging method of rpm and dpkg management software are quite different. Users who are used to the rpm package manager are usually not ...

AI Technical Summary

Problems solved by technology

[0009] 1. After installing the relevant package manager, there is no data of the installed package in the database of the package manager

[0010] 2. Mutual query is not supported

The software package information installed by dpkg cannot be queried using rpm; the software package information installed by rpm cannot be queried by dpkg

[0011] 3. Does not support interdependence processing

In the process of using rpm to install the rpm package, the situation that the rpm package depends on the deb package cannot be handled; in the process of using dpkg to install the deb format package, the situation that the deb package depends on the rpm package cannot be handled

[0012] 4. Does not support mutual conflict handling

This approach cannot detect conflicting cases, cannot handle conflicting cases

[0013] 5. Packaging tools do not support interdependence

[0014] 6. The yum installation of the rpm package cannot depend on the deb package, and cannot handle the conflict between the rpm package and the installed deb package; the apt installation of the deb package cannot depend on the rpm package, and cannot handle the deb package and the installed rpm package conflict between

[0016] 1. The method of converting the software package format cannot support rpm and dpkg at the same time, which cannot solve the problem of user habits

[0017] 2. Using Alien to convert the software package, there is information loss during the conversion process, which may cause installation failure or failure to install, uninstall and upgrade normally. For example, the software package converted by Alien lacks dependency information, and the installation script may convert incorrectly
