Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for acquiring a program running state according to an embodiment of the present invention. The method can comprise the following steps:
step 101: and in the running process of the target process, acquiring a memory image file corresponding to the target process.
The target process in this step may be a process (i.e., a program) that needs to detect the running state of the program. The memory image file corresponding to the target process acquired by the processor in this step may be an image file of the memory content of the target process at the time (i.e., the detection time) when the program running state is to be detected, that is, the memory image file collects the memory information of the target process at the detection time.
Specifically, the specific process of acquiring the memory image file corresponding to the target process in the process of running the target process by the processor in this step may be set by a designer according to a practical scenario and a user requirement, for example, in order to reduce the influence of the acquisition of the memory image file on the execution efficiency of the target process, the processor in this step may generate a child process of the target process when the memory image file needs to be acquired, and the child process may actively generate an abnormal signal to quit so as to generate the memory image file, because the memory content of the child process is completely the same as that of a parent process (the target process), the memory image file generated by the child process actively quitting (i.e., the memory image file corresponding to the child process) includes the memory content of the target process at that moment; that is to say, in this step, the processor may generate a sub-process of the target process, and cause the sub-process to actively exit abnormally, so as to obtain a memory image file corresponding to the sub-process; for example, after the processor receives a specific message (such as a preset state query instruction), the processor may generate a sub-process of the target process by using a message processing function and actively quit abnormally, so as to obtain a memory image file corresponding to the target process.
It can be understood that, in the process of running the target process by the processor in this step, the specific manner of obtaining the memory image file corresponding to the target process may be set by a designer according to a practical scene and a user requirement, for example, the processor may obtain the memory image file corresponding to the target process after receiving a preset state query instruction corresponding to the target process; namely, when a user needs to detect the program running state of the target process, the user can operate the human-computer interaction device to trigger a preset state query instruction corresponding to the target process, so that the processor can receive the preset state query instruction. The processor may also obtain the memory image file corresponding to the target process at preset time intervals. As long as the processor can obtain the memory image file corresponding to the target process in the running process of the target process, this embodiment does not limit this.
Specifically, the specific file Format of the memory image file in this step may be set by a designer, for example, the memory image file may be a file in ELF (Executable and Linkable Format); the file may also be a file in another format, as long as the memory image file may include the memory content of the target process of the image at the detection time, which is not limited in this embodiment.
Step 102: determining mirror image memory contents corresponding to each preset mark in the preset mark file according to the memory mirror image file and the preset mark file of the target process; the preset mark file comprises data information to be marked and mark name information corresponding to each preset mark.
It should be noted that, in this step, the preset markup file of the target process may be a preset file in which information (i.e., data information to be tagged) of memory contents (i.e., operation state data) that the target process needs to pay attention to in the operation process is recorded, so that the processor may determine, by using the preset markup file, mirror image memory contents that need to be paid attention to in the memory image file, i.e., mirror image memory contents corresponding to each preset tag in the preset markup file. The preset mark in this step may be category information corresponding to the memory content that needs to be paid attention to.
Correspondingly, the step can also include the step that the processor obtains the preset mark file of the target process before this step; for example, in the encoding stage of the target process, a designer or a user may record the running state data that needs to be paid attention to the markup file, so that the processor may run a memory image analysis tool to read and analyze the preset markup file, and determine the memory content that needs to be paid attention to.
Specifically, the specific content of the preset markup file in this embodiment may be set by a designer, for example, the preset markup file may include data information (such as the size of data) to be marked and tag name information corresponding to each preset markup; the preset mark file can also comprise display format information corresponding to each preset mark, so that the content of the preset mark file can be displayed in a format corresponding to the display format information on the interactive interface. As long as the processor can determine the mirror image memory content corresponding to each preset tag in the memory mirror image file by using the preset tag file, this embodiment does not limit this.
Correspondingly, the embodiment may further include a step of displaying the content in the preset markup file on the interactive interface, for example, the processor may display the content in the preset markup file on the interactive interface according to the received markup display instruction.
It can be understood that the purpose of this step may be that the processor determines the target mirror image memory content in the memory mirror image file, that is, the mirror image memory content corresponding to each preset mark, by using the memory mirror image file and the preset mark file of the target process, so as to obtain the memory content (that is, the operation state data) of the target process that needs to be concerned in the memory content at the detection time, thereby implementing the monitoring of the program operation state and facilitating the subsequent positioning of the problem.
Specifically, the specific manner in which the processor determines the mirror image memory content corresponding to each preset mark in the preset mark file according to the memory mirror image file and the preset mark file of the target process in this step can be set by a designer according to a practical scene and user requirements, for example, the processor can determine the mirror image memory content corresponding to each preset mark according to the preset mark file, the symbol table of the target process and the memory mirror image file; for example, the processor may operate a memory mirror image analysis tool to read and analyze a preset tag file, then read a symbol table of a target process, and establish association between a preset tag and a memory address; then, analyzing the memory mirror image file according to the file format of the memory mirror image file, and establishing the association between the memory address and the mirror image memory content in the memory mirror image file so as to obtain the association between the preset mark and the mirror image memory content; that is, this step may include determining a first correspondence relationship according to a preset markup file and a symbol table; determining a second corresponding relation according to the file format of the memory mirror image file; determining mirror image memory contents corresponding to each preset mark according to the first corresponding relation and the second corresponding relation; the first corresponding relation is the corresponding relation between each preset mark and the memory address, and the second corresponding relation is the corresponding relation between the memory address and the mirror image memory content. Correspondingly, when the processor marks corresponding preset marks in the memory content according to the preset mark file in the running process of the target process, the processor can preset the mark file and identify the mirror memory content corresponding to each preset mark in the memory mirror file; that is, the preset mark may be a specific identifier (such as a serial number ID), and correspondingly, the preset mark file may include specific identifier contents of each preset mark. As long as the processor can determine the mirror image memory content corresponding to each preset mark in the preset mark file according to the memory image file and the preset mark file of the target process, this embodiment does not limit this.
It should be noted that, this embodiment is exemplified by acquiring the program running state of one target process at one detection time, and the acquisition of the program running state of the target process at other detection times and the acquisition of the program running state of other target processes at any detection time may be implemented in the same or similar manner as the method provided in this embodiment, which is not limited in this embodiment.
Specifically, the step may further include the processor displaying, on the interactive interface, the mirror memory content corresponding to the target mark according to the received state display instruction; the state display instruction comprises target mark information, and the target mark is a preset mark corresponding to the target mark information. For example, when the target tag information is a tag name, the processor may run the memory image analysis tool to search and read corresponding image memory contents in the memory image file according to the memory address associated with the tag name in the state display instruction, and display the corresponding image memory contents in the interactive interface.
In this embodiment, according to the memory image file and the preset mark file of the target process, the mirror image memory content corresponding to each preset mark in the preset mark file is determined, and the memory information to be paid attention to in the memory image file can be obtained, so that the running state of the target process is determined, the program running state is obtained without using a log file, the problem of log flooding can be avoided, and the delay condition of the program is reduced.
