Positioning method of recording general progress anomal recede using sharing core-object

Abstract

The invention relates to a positioning method for recording the abnormal exit of a common process by using a shared memory object. It uses shared memory objects in the form of ring buffers to directly record the latest information of each common process, and sets the monitoring process to perform regular handshakes with common processes to determine whether any common process exits, which facilitates the positioning of abnormal process exits. . In addition, because the shared memory object uses the ring buffer to store information, the amount of stored information is greatly reduced, the memory overhead is reduced, and the running speed is improved.

Description

technical field [0001] The invention relates to a positioning method for common process abnormal exit, in particular to a method for recording the positioning information of common process abnormal exit by using a shared memory object. Background technique [0002] In product development, there are often situations where the system or ordinary process exits suddenly or terminates abnormally. Since the ordinary process has completely exited and no valid information is saved, the existing technology lacks an effective method for debugging and locating the problem. [0003] In the commonly used time-sharing operating system at present, common inter-process communication is realized by providing shared memory among common processes. A feature of shared memory is that when one of the ordinary processes exits, the relevant information will not be cleared. Therefore, we can use the method of writing shared memory to record the information recorded before the ordinary process exits,...

AI Technical Summary

Problems solved by technology

[0004] At present, there are two commonly used methods for locating problems: one is to analyze the locating problem by analyzing the core file after the common process exits, the disadvantage of this method is that the analysis requires considerable professional knowledge, and because the core file is automatically generated by the operating system , the programmer has no control over what should be logged

Another commonly used method is to record log files, but since we do not know in advance where there will be problems, in order to effectively and comprehensively analyze the problem, the amount of recorded information will be very large, and the overhead of recording files will also be very large

which in turn can seriously affect the speed of the system
