Method for synchronizing access to shared resources of a computing system and detecting and eliminating deadlocks using lock files

摘要

The disclosure generally relates to computer engineering, in particular, to a method for synchronizing access to shared resources of a computing system, and for detecting and eliminating deadlocks using lock files. The disclosure advantageously improves reliability of detection and elimination of deadlocks. The method grants access to a shared resource to other processes and ensures that there will be no deadlock in cases where the process, whose data is indicated in the lock file, does not currently exist in the computing system (for example, an application was aborted from RAM by the operating system due to an internal software failure). The method can be preferably implemented in POSIX-compatible operating systems, in particular, the GNU/Linux operating system.
