Abstract

Backward-compatible software allows to change its libraries without rebuilding and adapting the interface used for interaction between its components or other applications (application programming interface, API). Application binary interface (ABI) compatibility is important for application portability. There are ready-made solutions to verify binary compatibility, such as libabigail and ABI-compliance tools. Such tools have several disadvantages. For example, libabigail works only with libraries containing DWARF information. The ABI-compliance library can work without DWARF information, but it does not provide full information about the virtual method tables. The aim of this work is to solve the problem of compatibility verification for virtual method tables. Changes covered include when addition, removal and modification of records in such tables. The paper analyzes advantages and disadvantages of libabigail and ABI-compliance libraries related to binary compatibility issues and virtual method tables. Based on the analysis, we developed a new application free from the problems found in the libabigail and ABI-compliance libraries. We solved the dependency on DWARF information; realised ability to get full information about virtual methods tables and increased performance compared to competitors. The paper presents a comparative analysis of the algorithms when applied to libraries such as boost, libcds and others. Results show that the developed tool is effective when used in software applications to determine binary compatibility of virtual method tables.
