Abstract: Some examples described herein relate to dynamically applying a patch to a shared library. An external process may be invoked to bring target processes that refer to a shared library, to a safe point. In response to a function call from a target process, amongst the target processes, to access a target function in the shared library, the function call may be forwarded to a special function in a dynamic loader, wherein the target function is a function to be patched in the shared library. The special function may determine whether a shared patch library, comprising a patched version of the target function or a new function, is loaded for the target process. In response to determination that the shared patch library is not loaded for the target process, the shared patch library may be loaded only for the target process, and the request for the target function may be routed to the patched version of the target function or the new function, in the shared patch library.

Abstract: Some examples described herein relate to dynamically applying a patch to a computer application. An external process may be invoked to bring a target process of the computer application to a safe point. A dynamic loader may load a patch library into an address space of the target process, wherein the patch library includes a patched version of a target function or a new function. A specific function in the dynamic loader may be directed to route a function call for the target function to the patched version of the target function or the new function in the patch library.

Abstract: Some examples relate to storing memory profile data of an application in a non-volatile memory. In an example, source code of an application may be compiled into an instrumented code for generating profile data of the application. In an example, the profile data may include memory profile data related to memory usage of the application. Next, the profile data comprising the memory profile data of the application may be generated using the instrumented code. The application may be recompiled based on the profile data that includes the memory profile data of the application. Data for storing in a non-volatile memory (NVM) may be identified from the memory profile data of the application. The identified data may be stored in the NVM.
