example 1

[0064] The expression is actually a function, and the function takes environment variables, source code addresses, build dependencies, etc. as parameters of the function. Therefore, in the process of building the package, the required environment variables will be read and the source code will be obtained. An example of a function expression, that is, example 1, is as follows:

[0065]

[0066] The process of writing function expressions is as follows: figure 2 Shown:

[0067] S101, parameter definition

[0068] First define all the parameters required for software construction. The parameters are all the dependent packages required to build the software package. The first line of the above example shows that the three dependencies of stdenv, feturl and perl are required to build the hello package. Pass the names of dependent packages and dependent environment variables as arguments.

[0070] Call the component function fro...

example 3

[0096] After the function expression and the build script are written, run the build command to build; the built example 3 code is as follows:

[0097] 1ky-build-A hello

[0098] The package build process is as follows Figure 4 Shown:

[0099] S301. Create a build result symbolic link;

[0100] During the build process, a hidden resulting symlink is first created.

[0101] S302. Analyzing construction parameters;

[0102] Parse the parameters of the build command; the "-A" parameter in the above sample code indicates that the "hello" attribute is selected.

[0103] S303. Read and parse the function expression;

[0104] Read the written function expression, analyze the function definition in the expression, including function parameters and specific statements in the function expression.

[0105] S304, execute the build script;

[0106] Execute the build script; in the above example, builder.sh is executed. During the execution of the build script, the environment varia...

Abstract

The invention discloses a method of complete function-based multi-version software management on a Phytium platform. The method comprises the steps of: S1, carrying out construction of software packages on the basis of a complete function; and S2, generating corresponding hash values according to different construction environments of all the software packages, and using the hash values to mark the corresponding software packages. Compared with the prior art, the method has the advantages that the generated packages do not depend on existing software of an operating system, dependency does notexist among the packages, coexistence of multiple versions of software without a conflict can be allowed, and installation, upgrading and uninstallation of a user on software of a version needed thereby are facilitated.

Description

technical field [0001] The invention belongs to the technical field of operating systems, and in particular relates to a complete function-based multi-version software management method on a Feiteng platform. Background technique [0002] Most modern Linux operating systems provide a centralized package management mechanism to help users search, install and manage software. Software is usually stored in a warehouse in the form of packages, and the use and management of software packages is called package management. The basic components of a Linux package usually include: shared libraries, applications, services, and documents. Package management is often not limited to one-time installations of software, but also includes tools for upgrading installed packages. Package repositories help ensure that code has been audited on the system it is used on and managed by the software developer or package maintainer. Most package management systems are built on a collection of pac...
