Deadlock avoidance mechanism in multi-threaded applications

摘要

A computer-implemented method for implementing a deadlock avoidance mechanism to prevent a plurality of threads from deadlocking in a computer system wherein a first thread of the plurality of threads request for a first resource is provided. The computer-implemented method includes employing the deadlock avoidance mechanism to intercept the request. The computer-implemented method also includes examining a status of the first resource. The computer-implemented method further includes, if the first resource is owned, identifying an owner of the first resource, analyzing the owner of the first resource to determine if the owner of the first resource is requesting a second resource, and analyzing the second resource to determine if the second resource is owned by the first thread. The computer-implemented method yet also includes, if the first thread owns the second resource, preventing deadlocking by handling a potential deadlock situation.
