Repair method for parameter mismatching of callback function of module and related equipment

Abstract

The invention provides a method for repairing mismatched callback function parameters of a module and related equipment. The method comprises the following steps of: obtaining new parameters contained in a callback function type in a repairing program and original parameters contained in an upper callback function of a source program; comparing new parameters with original parameters, and taking different parameters in the new parameters and the original parameters as new parameter information; searching callback pointers about original parameter callback functions in all source programs, and informing an upper layer of allowing basic codes to call extended codes corresponding to newly-added parameter information to repair by utilizing virtual function interfaces corresponding to the callback pointers, so as to neglect the newly-added parameter information. Therefore, the processing logic of the received data is decoupled from the underlying data, an upper layer is notified to allow the basic code to call the extended code corresponding to the newly-added parameter information for restoration, and then the newly-added parameter information is ignored, so that the problem of program execution crash caused by parameter mismatching is solved.

Description

technical field [0001] The invention relates to the technical field of computer program software, in particular to a method for repairing mismatched parameters of a module callback function and related equipment. Background technique [0002] In program development, in order to decouple the code, it is usually used to set the pointer of the callback function to solve the decoupling relationship between the underlying function and the upper-level caller. The execution of the callback function pointer allows the caller to be notified after the execution of the underlying function is completed. [0003] However, the existing problem is that in many cases, program developers will develop the program in modules, and some modules have upgraded code functions, such as adding an additional parameter to an internal notification external callback function, while another module If you do not modify and add parameters to all the places where the callback is used, it will cause a crash p...

Problems solved by technology

[0005] The invention provides a method for repairing the mismatch of module callback function parameters. By searching for the callback pointers of the original parameter callback functions in all source programs, and calling the virtual function interface corresponding to the callback pointer of the callback class, based on the hook repair technology, it is ignored The new parameter information is added to solve the problem of program execution crash caused by parameter mismatch
