Program updating method and device and program migration method and device

Abstract

The embodiment of the invention provides a program updating method and device and a program migration method and device. The program updating method comprises: obtaining an original program file; reading a code file of the original program file, and converting the code file into an abstract syntax tree AST; traversing the AST, converting a static definition based on an original program framework in the AST into a static definition based on a new program framework, and adapting a dynamic calling object based on the original program framework in the AST into a dynamic calling object based on thenew program framework; and converting the modified AST into a code file. According to the embodiment of the invention, through converting a code file of a program file into AST, and converting the static definition based on the original program framework in the AST into the static definition based on the new program framework, the dynamic calling object based on the original program framework inthe AST is adapted to the dynamic calling object based on the new program framework, so that the code file can be automatically updated under the condition that the program framework is upgraded, andthe universality is very good.

Description

technical field [0001] The present application relates to the field of program technology, in particular to a program update method, a program update device, a program migration method and a program migration function device. Background technique [0002] The program framework is a system that provides program reusability. Developers can develop program files on the program framework based on business needs. [0003] With the development of program design, some old program frameworks cannot meet the needs of business development, so the program framework needs to be upgraded. When the program framework is upgraded, the program files developed based on the original program framework cannot run normally under the new program framework. [0004] Due to the upgrade of the program framework and the adjustment of programming models such as syntax and timing, it is difficult to be directly compatible with the adapter interface. Even if it is compatible, it will cause a heavy main...

Problems solved by technology

[0003] With the development of program design, some old program frameworks cannot meet the needs of business development, so the program framework needs to be upgraded

When the program framework is upgraded, the program files developed based on the original program framework cannot run normally under the new program framework

[0004] Due to the upgrade of the program framework, which involves the adjustment of programming models such as syntax and timing, it is difficult to be directly compatible with the adapter interface

Even if compatible, it creates a heavy maintenance burden and unpredictable problem legacy for new framework code

For this upgrade method, it is usually necessary to manually reconstruct the program files, but the manual reconstruction method is inefficient and not universally applicable. When there are many historical businesses, it is time-consuming and laborious.
