Abstract
A race condition detection system and method statically detects potential race conditions in a multi-threaded computer program. The race condition detector builds a synchronization graph representing at least a subset of a computer program's method declarations, field declarations, and synchronization statements. Edges are constructed between the nodes representing execution paths in the computer program. Each node is associated with a set of lock designations that correspond to all locks that are consistently held along all executions paths in the computer program to the respective node. The race condition detector analyzes this information to determine whether accesses to object data fields are consistently protected by an appropriate lock. An object data field access that is not protected by an appropriate lock indicates a potential race condition. At least a subset of indicated potential race conditions are reported.
