Hot updating method and device

Abstract

The invention discloses a hot updating method and device. The method comprises the steps that whether a program running at present needs hot updating or not is detected; when it is determined that the program needs hot updating, a hot updating execution code is acquired from a server; the hot updating execution code comprises identification information used for identifying a variable or function needing to be updated in a module of the program and an updated content code used for replacing a local content code of the variable or function needing to be updated in a memory; the hot updating execution code is operated, the variable or function needing to be updated is looked up according to the identification information, and the updated content code replaces the local content code of the variable or function in the memory to update content of the variable or function; when an object created by a module calls the variable or function, the updated content code serves as the content of the variable or function to be operated. According to the method, the hot updating process of a client can be simplified, traffic needed by hot updating is decreased, and limitation that a developer is subjected when the developer writes a hot updating code is reduced.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a thermal update method and device. Background technique [0002] In the Internet field, it is often necessary to urgently repair and update modules that have problems in the released clients on the server side to ensure system stability and user experience. [0003] In the prior art, the hot update usually adopts the reload method to reload the problematic modules. Specifically, the developer updates the problematic script module, and pushes the updated script module to the client after the test passes. After the client receives the updated script module, it compiles the script module in real time, and then uses reload to reload the corresponding module. After reloading, the program calls the new module at runtime, and generates a new object through the new module . [0004] However, if the old module has been loaded into memory, the old object created by the old mo...

Problems solved by technology

[0008] However, reload only solves the problem of loading new code, and the old Person object that has been created in the program has not changed. The method of judging whether a person is young in the old Person object is still wrong

Therefore, in order to completely update the problem, it is also necessary to traverse all existing Person objects to refresh the methods and variables in them, which is quite tricky and time-consuming

[0009] At the same time, since all Python scripts with problems need to be pushed, when the problems are distributed in multiple modules or the code volume of the module is large, users need to consume more traffic to obtain the updated scripts

[0010] In addition, using the reload method for hot updates has many limitations for developers
