Software debugging log output control achievement method

Abstract

The invention particularly relates to a software debugging log output control achievement method. The software debugging log output control achievement method adopts a function log control module and a function log output module. Functions needing to open log output are added into a Hash table for achieving log switching, and character string values of source program file names and function names are used for conducting Hash calculation of the Hash table and conflict detection is performed according to Hash values; log output points perform Hash search according to the character string values of the source program file names and the function names and perform log output for the functions opening log output. The software debugging log output control achievement method utilizes the character string values of the source program file names and the function names to perform Hash calculation and controls output of function logs in a matched mode, and performance loss caused by log control can be effectively reduced at the high-performance requests of driver development and the like.

Description

technical field [0001] The invention relates to the technical field of computer software debugging, in particular to a method for realizing software debugging log output control. Background technique [0002] In recent years, with the continuous development of computer technology and the diversification of economy and lifestyle, people's demand for computer application software in work and life is increasing. With more and more types of application software and larger scale, in order to make the computer operate more efficiently, the current software generally adopts multi-threading technology. However, as the scale of software becomes larger and larger, the complexity of debugging becomes higher and higher. Therefore, in order to facilitate future query, tracking and analysis by the operator, the system will generate a log to record the behavior and status of each thread running. [0003] During the driver software development process or after the software is deployed to ...

[0009] (2) Number analysis method: analyze a set of data, such as the date of birth of a group of employees. At this time, we find that the first few digits of the date of birth are roughly the same. In this case, the probability of conflict will be very high. However, we found that the last few digits of the year, month, and day indicate a large difference in the number of the month and the specific date. If the latter digits are used to form a hash address, the probability of conflict will be significantly reduced.
