Abstract: Embodiments of the present disclosure relate to the field of cloud computing, and specifically to a method, apparatus, device, and computer storage medium for upgrading an application. The method may include: determining, for a first thread executed by a first process of a first application, a first function invoked by the first thread; determining a second function corresponding to the first function in a second application, the first application to be upgraded to the second application, and the first function to be upgraded to the second function; replacing a first dynamic link library of the first application comprising the first function based on a second dynamic link library of the second application comprising the second function; and updating the first process based on the second dynamic link library, such that the updated first process runs the second function in the second application.

Abstract: The present application discloses a method and apparatus of unloading an out of memory (OOM) processing flow to a user space. A specific implementation of the method includes: writing related information of an OOM event into a memory page shared by a user space and a kernel space when a process triggers the OOM event, the related information comprising: an identification of the process and a path of a memory resource control sub-system where the process exists; acquiring, by an OOM service process of the user space, the related information of the OOM event through the memory page; and processing, by the OOM service process of the user space, the OOM event using the related information of the OOM event.
