Abstract
The invention discloses a debugged program debugging method based on a core-implanted debugger, belonging to the technical field of computer software. The method comprises the following steps: (1) the debugger is divided into a core work module and a human-computer interaction interface module; (2) the core work module and the human-computer interaction interface module are placed into two different processes of one host respectively for realizing; (3) a debugging command received by the human-computer interaction interface is transmitted into a host process in which the core work module is positioned by the human-computer interaction interface through process communication, and then is transmitted to the core work module of the debugger through the host process; and (4) debugging data acquired from a debugged process in the debugging process is transmitted to the core work module of the debugger through process communication by the host process, and then is analyzed and displayed by the human-computer interaction interface module. The invention provides the debugging method aiming at the anti-debugging method for detecting process of a debugger, can fast develop the human-computer interaction interface, and improve the debugging expansibility.
Description
Technical field
The invention belongs to the reverse debugging technique of computer program field, relate to a kind of method of work that can debugged program and debugger be isolated fully.
Technical background
The debugger that existing market is popular has a lot, can realize computing machine the assembler code dynamic debugging and the internal memory of program compiler through the mode of dynamic decoding, register, and the demonstration of stack information has made things convenient for the debugging of staff to debugger.
But all there is a problem in these debuggers, and debugged program and debugger directly articulate.So just produced a problem, debugged program can detect the existence of debugger through relevant technological means, thereby increases some anti-debug functioies to certain debugger.
Simultaneously, because the kernel program and the human-computer interaction interface of debugger intercouple, be difficult to utilize existing debugger to carry out the exploitation of new human-computer interaction interface.
Summary of the invention
The present invention is directed to debugger and debugged program and directly articulate the problem that can't change the man-machine interaction page with the debugger core function fast; A kind of debugged program debugging method based on the pouring-in debugger of core has been proposed; When having isolated debugger and debugged program fully, also increased the extendability of debugger human-computer interaction interface.The present invention is divided into core work module and two functional modules of human-computer interaction interface through having debugger now; Be put into respectively in two detached processes; Wherein the function of debugger core operational module is to obtain tune-up datas such as the decoding information of debugged program in the debug process, memory information, stack information, register information to pass to the human-computer interaction interface module by host's process through process communication, and the human-computer interaction interface module is used to resolve the output data of debugged program and the debug command that receives user's input.
Major technique of the present invention thes contents are as follows:
1) is placed on the core work module of debugger and human-computer interaction interface module respectively in two detached processes of same host's main frame and realizes; The debugger core operational module is injected in any process of host's main frame, and making the observable debugger process of debugged program have infinite kind maybe.
2) the human-computer interaction interface module is placed on independently in the interface process, will be imported in host's process by the debug command of interface input through process communication, passes to the debugger core operational module by host's process again, and debugged program is debugged action accordingly.The present invention connects debugged program and any host's process through system kernel, is communicated by letter with interface process by host's process again, has overcome prior art and through system kernel debugger and debugged process has been connected the problem of bringing.Host's process be meant the debugger core operational module parasitic process parent, interface process be independently one be used for interface display and user interactions process.
3) the debugger core operational module is with the decoding information of obtaining from debugged program in the debug process; Memory information; Stack information; Tune-up datas such as register information pass to human-computer interaction interface by host's process through process communication, resolve and be shown to the user by the human-computer interaction interface module according to communication format again.
4) under the situation of the output of following debugger core and input data layout, can develop different human-computer interaction interfaces fast, not need to consider again the logical process flow process of debugger.
Technical scheme of the present invention is:
A kind of debugged program debugging method based on the pouring-in debugger of core the steps include:
1) debugger is divided into core work module and human-computer interaction interface module; Wherein, said core work module is used for obtaining the debugged program debug data of debug process, and said human-computer interaction interface is used to resolve the output data of debugged program and the debug command that receives input;
2) said core work module and said human-computer interaction interface module are placed on respectively in the two different detached processes of same host's main frame realize;
3) said human-computer interaction interface module is imported into the debug command that receives in host's process at said core work module place through process communication; Pass to said debugger core operational module by this host's process again, debugged program is debugged action accordingly;
4) said debugger core operational module passes to said human-computer interaction interface module by host's process through process communication with the tune-up data that obtains from debugged program in the debug process, again by said human-computer interaction interface module parses and demonstration.
Further, said debugged program and said core work module are arranged in same process.
Further, said debugged program is arranged in a detached process of said host's main frame.
Further, said tune-up data comprises: decoding information, memory information, stack information and register information.
Further, said debugger core operational module is injected into any process of said host's main frame through the mode of DLL injection.
Further, select said host's process through said human-computer interaction interface module.
Further, said core work module starts said debugged program through the debugged device Program path from said human-computer interaction interface module input.
Compared with prior art, the invention has the beneficial effects as follows:
After adopting the present invention, the developer can utilize the debugger core module to be injected into the debugged program of debugging in host's process.Relevant Debugging message and debug command can be passed through the corresponding interface input and output; The developer can develop corresponding human-computer interaction interface fast according to different application sublimity like this; And in this course of work, debugger and debugged program are isolated fully, and debugged program can only detect host program; And can't detect real debugger program, make the relevant anti-adjustment method complete failure that detects to the debugger process.The present invention realizes the isolation fully of debugger and debugged program, let debugged program instrumentation to debug procedures have infinite maybe.
Can improve the extendability of debugging fast according to the needs exploit person machine interactive interface of environment.
