Problems solved by technology

[0003] In the prior art, the method for grabbing the Dump file is to use in-process grabbing, but it has the following disadvantages: when the process crashes abnormally, the process is in an unstable state, and if the Dump file is grabbed in the process at this time, it may be Destroy the crash site, resulting in incorrect dump results; some processes do not support in-process dump operations, such as the rendering process, because it does not have permission to access the file system, so it cannot generate a dump file

Abstract

The invention provides a Dump file capture method and device and equipment. The method comprises the steps that S1, when a pre-created monitoring process receives an abnormal crash signal of a to-be-monitored program, a Dump file is created in the monitoring process; S2, crash data of the to-be-monitored program is read according to the ID of the to-be-monitored program in the monitoring process,and the crash data is saved into a memory through a predefined processing function; and S3, a writing function corresponding to the Dump file is called in the monitoring process to write the crash data into the Dump file. According to the Dump file capture method and device and the equipment, a crash spot of the to-be-monitored program is captured through the pre-created monitoring process, the Dump file is generated, in-process capture of the to-be-monitored program is avoided, and the completeness and correctness of the Dump file are improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device and equipment for grabbing Dump files. Background technique [0002] Dump files are mainly used to diagnose the running status of a process. When the program encounters an abnormal crash problem during the running of the program, it records system information and program running stack information, and is used for programmers to analyze and debug the file of the cause of the program crash. [0003] In the prior art, the method for grabbing the Dump file is to use in-process grabbing, but it has the following disadvantages: when the process crashes abnormally, the process is in an unstable state, and if the Dump file is grabbed in the process at this time, it may be Destroy the crash site, resulting in incorrect dump results; some processes do not support in-process dump operations, such as the rendering process, because it does not have permission to access the ...
