Problems solved by technology

However, this command can only target dynamic libraries, not static libraries, and can only analyze whether there is a dependency relationship between binary object files, but cannot analyze whether there is a circular dependency between these binary object files, etc.

Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] An embodiment of the present invention provides a method for analyzing module dependencies, which includes:

[0041] Obtain all non-system modules in the software to be analyzed to construct a module group;

[0042] Get the dependencies between all modules in the module group;

[0043] Establish a dependency relationship matrix representing the dependency relationship between all modules in the module group, and judge whether there is a circular dependency relationship between non-system modules in the software to be analyzed according to the dependency relationship matrix.

[0044] The modules in the software to be analyzed include system modules and non-system modules. Taking binary object files implemented in C language as an example, modules are binary object files that can form the final executable file. System modules re...

Abstract

The invention discloses a module dependency analysis method and system, and relates to the technical field of communication. The analysis method of module dependency includes: obtaining all non-system modules in the software to be analyzed to construct a module group; obtaining the dependency relationship between all modules in the module group; establishing a pairwise relationship representing all modules in the module group The dependency matrix of the dependencies among them is used to determine whether there is a circular dependency between the non-system modules in the software to be analyzed according to the dependency matrix. The invention can determine whether there is a circular dependency between the binary target files as modules in the software to be analyzed.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method and system for analyzing module dependencies. Background technique [0002] Modular design is an important method of software design, and module design should follow the principle of high cohesion and low coupling. Cohesion is a measure of the degree of association between components within a module, and coupling is a measure of the interconnection between modules. The coupling relationship between modules refers to the dependency relationship between modules, including control relationship, reference relationship and data transfer relationship. [0003] The control of module dependencies is carried out in the software design stage, and the analysis of module dependencies is aimed at the post-evaluation and measurement of the products delivered by software development. When the design does not conform to the principle of high cohesion and low coupling, or the d...
