Static detection of a datarace condition for multithreaded object-oriented applications

摘要

A static datarace detection method (and apparatus) for multithreaded applications includes inputting a set of input information including a multithreaded context graph (MCG) representation of a multithreaded application, processing the set of input information, and outputting a statement conflict set (SCS). The SCS is a set of statement pairs that may exhibit dataraces. The processing of the set of information includes initializing a synchronization object set for each of a plurality of MCG nodes, performing a nested traversal on the MCG to identify pairs of MCG nodes which are not mutually synchronized, and examining each pair of MCG nodes which are not mutually exclusive to determine if pairs of statements in the nodes represent a datarace by considering objects that can be accessed by the statements.
