Multi-version asynchronous dynamic software update system and method for applications with multiple threads

摘要

A method and system for using multiple versions of a software component, includes storing, in memory, a first function table that points to executable code in the memory for functions from a first version of the software component, and storing, in the memory, a second function table that points to executable code in the memory for functions from a second version of the software component, referencing the first function table, when running a first application thread, to execute the functions from the first version of the software component; and referencing the second function table, when running a second application thread that is active concurrently with the first application thread, to execute the functions from the second version of the software component.
