A method, device, medium and electronic equipment for obtaining memory leak information

Abstract

The disclosure provides a method, device, medium and electronic equipment for acquiring memory leak information. The method includes: the main process obtains its abnormal crash information; based on the triggering of the abnormal crash information, the main process creates and runs an emergency sub-process; the emergency sub-process obtains the memory state information shared by the main process, and saves it in the memory state Data collection; when the main process runs again, obtain memory state information from the memory state data set; when the memory state information meets the memory exception condition, the main process generates memory leak information. The disclosure directly acquires the size information of the virtual memory, thereby quickly locating the memory leak information, and accurately aggregates the memory leak information, thereby improving the efficiency of locating program faults. Creating a copy-on-write subprocess reduces the interference of other threads and / or processes, avoids interrupting the exception handling process, and improves the success rate and stability of obtaining exception information.

Description

technical field [0001] The present disclosure relates to the field of locating process exceptions, in particular, to a method, device, medium and electronic equipment for acquiring memory leak information. Background technique [0002] C language is a process-oriented, abstract general-purpose programming language, which is widely used in low-level development. C language has the characteristics of high efficiency, flexibility, rich functions, strong expressive power and high portability, and is favored in programming. C language compilers are ubiquitous in various operating systems, such as Microsoft Windows, macOS, Linux, Unix, etc. The design of the C language has influenced many subsequent programming languages, such as C++, Objective-C, Java, C#, etc. [0003] C++ was originally called C with classes. It is an object-oriented computer programming language. It is a general-purpose programming language that checks static data types and supports multiple programming par...

Problems solved by technology

However, it also has obvious defects. For example, problems such as wild pointers and memory leaks have always plagued developers.

The traditional memory leak monitoring solution is to obtain memory leak information through the aggregation of abnormal call stacks. Because the cause of memory leaks is not directly related to the call stack, it is inefficient to monitor memory leaks through the call stack.
