Title:
IMPACT ANALYSIS DEVICE, IMPACT ANALYSIS METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/084623
Kind Code:
A1
Abstract:
This impact analysis device involves: acquiring, on the basis of a source code of a new version library and a source code of an old version of the library, a list of method information relating to a difference between the new version library and the old version library; extracting, from the list, a first difference relating to a method present in a first call graph of software which uses the old version library; extracting, from the list, a second difference relating to a method added to a second call graph, of the software, which uses the new version library; extracting a set of method information items on a call side of transition that have been added to the second call graph as compared to the first call graph; and outputting the union of the first difference, the second difference, and the set, thereby improving assistance in determining a possibility of impact of library update on the operation of the software.
