Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Main thought of the present invention is: analyze dump file and export analysis result; Resolve the analysis result of described output, obtain analyzing the crash info that crash reason need be used; The dump file of resolving is sorted out, and the result after the storage classification.
Fig. 1 is the process flow diagram of the automatic analysis method of computer software crash info of the present invention.As shown in Figure 1, automatic analysis method of the present invention mainly may further comprise the steps:
Steps A, analyze dump file and export analysis result.
In this step, specifically comprise: open a dump file; From described dump file, obtain breakdown address, mistake number, collapse thread, and then obtain the storehouse of collapse thread and the storehouse of other threads; The above-mentioned information that output is obtained from described dump file is for example preserved with the form of text.
In practice, the debugger that can call the Debugging Tools for Windows kit of Microsoft and provide is analyzed dump file.Debugging Tools forWindows kit provides 4 debugger: CDB, NTSD, KD and WinDbg at present, and may change along with the continual renovation of version.
Call debugger, the path and the filename of input dump file (dump file) can also be imported path, source code path, the command script of path, the symbol file (PDB file) of image file or preserve one or more parameters in the filename of output analysis result.
Can import above-mentioned parameter with several different methods, to be that the method that debugger carries out the storage file analysis is called in the example explanation in the Windows system by order line input above-mentioned parameter, parameter-z is used to specify dump file path and filename in order line below; Parameter-i is used to specify the path of image file; Parameter-y is used to specify the path of symbol file; Parameter-srcpath is used to specify the source code path; Parameter-c is used to specify and analyzes order; Parameter-cf is used to specify the analysis computer command script document; Parameter-logo or-loga is used to specify the analysis result output file.
Analysis order in the order line comprise at least automatic analysis order (! Analyze), in demonstration stack command (k or kb), exit command (q) and the display module order (lm or lmvm).
Provide an example of analyzing dump file by the order line input parameter below:
cdb-z“c:\dump\test.dmp”-y“c:\symbols”-c“！analyze-v；lmvmfetion；q”-logo“c:\dump\test.log”
Dump file path and file " c: dump test.dmp " by name are specified in last example expression, the path of symbol file is " c: symbols ", designated analysis output file as a result is " c: dump test.log ", specify the debug command of CDB debugger to be "! Analyze-v; Lmvmfetion; Q ", in the debug command "! Analyze-v " expression output detailed results, " lmvm fetion " expression output name is called the details of the module of fetion, and " q " expression is withdrawed from after analyzing and finishing automatically.
The analysis result of step B, the described output of parsing obtains crash info.
The analysis result of exporting in the steps A is generally preserved with the form of text, and by resolving the corresponding text file, can obtain in the following crash info one or more at least: the operating system and the version of the main frame of collapse takes place (1); (2) time of collapse generation; Register information when (3) collapse taking place; (4) cause the process title of collapsing; (5) collapse code and reason; (6) breakdown address; (7) cause the thread stacks of collapsing; (8) cause the Thread Id that collapses; (9) cause the module title of collapsing; (10) cause the information such as path, version of the module of collapsing.
Step C, the dump file of resolving is sorted out, and the result of storage after sorting out.
The dump file that is about to resolve is sorted out according to crash reason, and crash reason is identical is classified as a class.
In this step, during the identical dump file of crash reason sorted out, use table 1 record crash reason:
Table 1
In table 1, provided the example of a record crash reason; The address of the instruction that the 02840e19 in the breakdown address field carries out when representing program crashing is 0X02840e19.
Function calling relationship when having put down in writing program crashing in the collapse storehouse field in the storehouse, each row in the storehouse is represented a function call.Article one, (top line) is the function that collapse the time is called, the second function call article one function, the 3rd function call the second function, the rest may be inferred.
The operating system field record version number of program run place operating system.Data show it is Windows XP 2600 versions in the table, and have beaten Service Pack 3 patches.
The module release field record causes the version number of the module of collapsing, i.e. 4.0.2510.0, and this module generally is an executable program (exe) or dynamic link library (dll).
At least comprise in breakdown address field and the collapse storehouse field in the above-mentioned table 1, can also comprise operating system field and module release field or the like in this table 1, do not enumerate one by one here.
Fig. 2 is a method flow diagram of in the inventive method the dump file of resolving being sorted out and stored the result after sorting out.As shown in Figure 2, the step that the crash info A that parses is sorted out comprises:
Whether there be the row identical in step C1, the definite table with the breakdown address of crash info A.If exist then finish, if there is no forward step C2 to.
Whether there be the row identical in step C2, the definite table with the collapse storehouse of crash info A.If exist then finish, if there is no then forward step C3 to.
Whether have crash info B in step C3, the definite table, the collapse storehouse of described crash info A is a subclass of the collapse storehouse of described crash info B, if exist then end, otherwise crash info A is joined in the table.
The present invention also comprises the simplification to above-mentioned steps, if promptly only used some steps or certain two step among step C1, step C2 and the step C3, is also contained within the present invention.
Fig. 3 is the structural drawing of the automatic analysing apparatus of computer software crash info of the present invention.As shown in Figure 3, automatic analysing apparatus of the present invention mainly comprises: dump file analysis module 1; The analysis result parsing module 2 that is connected with dump file analysis module 1; The crash reason classifying module 3 that is connected with analysis result parsing module 2; Described dump file analysis module 1 is used to analyze dump file and analysis result is outputed to analysis result parsing module 2; Described analysis result parsing module 2 is used to resolve the analysis result that is received from described dump file analysis module 1, obtains analyzing the crash info that crash reason need be used, and the crash info that obtains is sent to crash reason classifying module 3; Described crash reason classifying module 3 is used for the dump file of resolving is sorted out, and the result after the storage classification.
As can be seen from the above embodiments, the embodiment of the invention has proposed a kind of automatic analysis method and device of computer software crash info, by calling the debugger analysis crashdump file that Debugging Tools forWindows kit provides automatically, it is accurate comprehensively to obtain crash info; Use breakdown address and collapse storehouse that crash info is sorted out, not only improved the classification accuracy, and significantly reduced the redundant information of storage in the table.Use the present invention, personnel are calculated in this area can know crash reason exactly, foundation is provided for solution software fault and Optimization Software.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
