Title: PERSISTENT AND RESILIENT WORKER PROCESSES
Abstract:
In the field of computing, many scenarios involve the execution of an application within a virtual environment (e.g., web applications executing within a web browser). In order to perform background processing, such applications may invoke worker processes within the virtual environment; however, this configuration couples the life cycle of worker processes to the life cycle of the application and/or virtual environment. Presented herein are techniques for executing worker processes outside of the virtual environment and independently of the life cycle of the application, such that background computation may persist after the application and/or virtual environment are terminated and even after a computing environment restart, and for notifying the application upon the worker process achieving an execution event (e.g., detecting device events even while the application is not executing). Such techniques may heighten the resiliency and persistence of worker processes and expand the capabilities of applications executing within virtual environments.
