Method, apparatus, device and storage medium for upgrading application

An apparatus for upgrading an application, comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions when executed by the at least one processor, causing the at least one processor to perform operations, the operations comprising:
• 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.

A non-transitory computer readable storage medium, storing a computer program thereon, wherein the program, when executed by a processor, causes the processor to perform operations, the operations comprising:

• 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.
