Automatic Comparison of Static Analysis Outputs on Different Versions of Programs
Kompová, Radmila ; Müller, Petr (referee) ; Vojnar, Tomáš (advisor)
This thesis aims at development of a tool support for comparing the output of static analysis applied to different versions of program source codes. The thesis also comprises a discussion of three opensource static analyzers of the C source code. Based on this discussion, one of these analyzers, Cppcheck, was chosen for the implementation of the designed tool. The static analyzer's outputs, obtained for various versions of a specific program, are compared on the basis of the context of the line at which an error was found. The patch utility is used for comparing the appropriate contexts. Detected errors are classified into three groups: new, old, and fixed errors. A web interface allowing an easier-to-follow presentation of the results is also provided. The designed tool set has been successfully tested on three opensource projects, including the Linux kernel, Coreutils and CPython.
