Source Code Analysis Apparatus Reducing Dynamic Analysis Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale software development projects, dynamic analysis methods require excessive time due to the increased number of input value combinations, making it challenging to analyze source codes efficiently without compromising accuracy.
Innovation Solution
A source code analysis apparatus that includes a change function extract processing unit, an analysis necessity determination processing unit, and an analysis result processing unit, which limits the analysis to only the change function and its influence functions based on input value ranges, reducing the scope of analysis and thereby the analysis time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dynamic analysis method is used to analyze source codes in large-scale software development projects, then analysis accuracy is improved, but analysis time is significantly increased
Solution Approach 1:
The patent segments the source code into multiple units and performs dynamic analysis on each unit separately rather than analyzing the entire codebase at once. This division allows the analysis to focus on specific portions, reducing the overall analysis time while maintaining comprehensive coverage through systematic segmentation of the code base
Solution Approach 2:
The patent extracts and prioritizes critical functions and code paths that are most likely to contain failures. By identifying and focusing analysis efforts on these high-risk areas rather than uniformly analyzing all code, the system achieves effective failure detection with reduced analysis time
Solution Approach 3:
The patent performs preliminary static analysis before dynamic analysis to identify potential failure points and prioritize code sections requiring dynamic analysis. This preliminary assessment allows the system to prepare analysis targets in advance, reducing the time required for actual dynamic analysis while maintaining accuracy
2Reliability
If all functions in post-change source code are analyzed, then analysis completeness is improved, but analysis time is increased
Solution Approach 1:
The patent applies different analysis strategies to different parts of the codebase based on their characteristics and risk levels. Critical functions undergo thorough dynamic analysis while less critical areas receive streamlined analysis, allowing comprehensive coverage with optimized time investment for each specific code region
Solution Approach 2:
The patent performs analysis on a selectively reduced set of functions that are most relevant to the changes made, rather than analyzing all functions. This partial analysis approach focuses computational resources on the most impactful areas while still providing sufficient assurance of code quality

AI summary
A time period required for analyzing a source code is reduced without reducing analysis accuracy in a source code analysis apparatus that analyzes a source code with a dynamic analysis method. An analysis processing unit extracts, from a post-change source code, an influence function to which an input is given by a change function. An analysis necessity determination processing unit determines whether or not the function is the analysis target function, based on a range of an input value input to the change function and a function included in the influence function. The analysis processing unit performs an analysis of the analysis target function, which is included in the change function and the influence function. An analysis result processing unit outputs an analysis result of the post-change source code, which includes an analysis result of the analysis target function.
