In the present embodiment, after server gets exception stack information, need exception stack information is analyzed, fromAnd determine collapse object.In one implementation, all stack informations in exception stack information are analyzed by server,To determine collapse object.
Owing to some collapse is to be caused by the exception object in code, some collapse is not caused by exception object,And the collapse only caused by exception object could be revised code by developer and repair, therefore, in order to avoid to not leading toCross and repair the collapse object that exception object repairs and be analyzed wasted resource, in another kind of implementation, serverBefore exception stack information is analyzed, it is also possible to filtering out is not the stack information of the collapse caused by exception object.Wherein, there is the object of code error in exception object in being a destination code.Such as, when in item destination code, certain pointer is notWhen pointing to significant internal memory, server determines that the function calling this pointer writes mistake, and the present embodiment is by the most different for this functionOften object.
Generally, exception object the collapse caused has fixed type, and server can read institute from exception stack informationThere is the collapse type of stack information, be that the stack information of the first kind retains to collapse type, be non-the to collapse typeThe stack information of one type is deleted, and obtains exception stack information.That is, exception stack information is obtained, including: obtain collapse classType is the exception stack information of the first kind, and the first kind is the type of the collapse caused by exception object.
Wherein, the first kind can include SIGSEGV and SIGBUS.When SIGSEGV is to quote invalid address in codeThe collapse type of the collapse caused, the type of the collapse that SIGBUS causes when being and quote illegal address in code.
Step 202, obtains the first abnormality code information being scanned obtaining, the first abnormality code letter to item destination codeEach exception object of code error is there is in breath in indication item destination code.
In the present embodiment, server uses the code scans instrument preset to be scanned item destination code, scanning is tiedFruit is as the first abnormality code information.Wherein, server can first scan code, the first abnormality code information obtained is carried outCaching, reads the first abnormality code information again when getting exception stack information；Can also first obtain exception stack information, thenScan code obtains the first abnormality code information；Abnormal heap can also be obtained when scan code obtains the first abnormality code informationStack information, the present embodiment is not construed as limiting.
In the present embodiment, code that exception stack information is corresponding and code corresponding to the first abnormality code information need phaseWith, therefore, refer to Fig. 3, obtain the first abnormality code information being scanned item destination code obtaining, also include:
Step 2021, reads the project label that exception stack information is corresponding.
Project label is for identifying project during code scans, and project label can be that server creates the project time-divisionJoin, it is also possible to being server distribution when the project of issue, the present embodiment is not construed as limiting.Wherein, project label can beapp_id。
Step 2022, determines that in the first incidence relation the project key assignments corresponding with project label, the first incidence relation are usedIn the corresponding relation recorded between different project labels and different project key assignments.
Project key assignments is for identifying project during collapse reports, and project key assignments can be that server is when the project of establishmentDistribution, it is also possible to being server distribution when receiving the collapse object of terminal to report, the present embodiment is not construed as limiting.ItsIn, project key assignments can be project key.
In the present embodiment, user also needs to set up the first incidence relation for project label and project key assignments, abnormal to associateStack information and the first abnormality code information.Therefore, the first incidence relation determines the project key assignments corresponding with project labelBefore, also include: receive the configuration operation that user triggers when the first abnormality code information of the project of checking；Display includes projectThe configuration interface of project key assignments；Receive the project label that user inputs in configuration interface；By project key assignments and project labelCorrespondence is added in the first incidence relation.
Refer to Fig. 4, after code scans instrument obtains the first abnormality code information, server display configuration is different with firstThe configuration interface of the exception stack information that often code information is associated, now, configuration interface includes that this first abnormality code is believedThe project key assignments that breath is corresponding, also includes the input frame of project label, when user's cuit in this input frame in configuration interfaceMark, and when triggering association control, server sets up the first incidence relation of project key assignments and project label.
Optionally, configuration interface also includes the information such as project name, language form, version number, the most regularly association, itsIn, project name is used for described project, and language form is for the language of the code of described project, and version number is for described projectVersion, if whether timing associates the first abnormality code information and exception stack information for describing in fixed pattern association.
Step 2023, the item destination code indicated by key assignments of identifying project.
Step 2024, obtains the first abnormality code information being scanned obtaining to item destination code.
After item destination code is scanned by code scans instrument, the corresponding exception of every scanning result obtained is rightAs, and a scanning result includes exception object, type of error, line number etc..
In the present embodiment, after server gets the first abnormality code information, need the first abnormality code information is enteredRow is analyzed, so that it is determined that exception object.In one implementation, server is to all scannings in the first abnormality code informationResult is analyzed, to determine exception object.
Owing to some exception object can't cause collapse, and the collapse only caused by exception object could be by exploit personMember's amendment code is repaired, therefore, in order to avoid the exception object that can not cause collapse being analyzed wasted resource,In another kind of implementation, server is before being analyzed the first abnormality code, it is also possible to filters out and will not cause collapseThe scanning result of exception object.
Generally, it is possible to cause the exception object of collapse to have fixed type, server can be from the first abnormality code informationRead the type of error in all scanning results, the scanning result that type of error is Second Type is retained, to mistake classThe scanning result of the non-Second Type of type is deleted, and obtains exception stack information.That is, item destination code is scanned by acquisitionThe the first abnormality code information arrived, including: being scanned item destination code, obtaining type of error from scanning result is secondFirst abnormality code information of type, Second Type is the type of the exception object causing collapse.
Wherein, Second Type is relevant to the code speech of code.When code speech is C++, Second Type can includeNull pointer and crossing the border.Null pointer refers to that code pointer is not directed to significant internal memory, cross the border refer to code is not the mostThis pointer storage allocation space.When code speech is C#, Second Type can include that overflow exception, index range are abnormal and emptyQuote exception.Overflow exception refers to that the arithmetical operation conducted in the context chosen in code, type conversion or conversion operateCause overflowing, when index range refers to pass through index accesses data in code extremely, index beyond the index range set, emptyQuoting the content referring to quote in code is sky.
Step 203, according to exception stack information and the first abnormality code information, determine associated by each collapse object is differentOften object.
Refer to Fig. 5, according to exception stack information and the first abnormality code information, determine associated by each collapse objectException object, including:
Step 2031, extracts the first mark of each collapse object from exception stack information.
First mark is used for indicating collapse object.Such as, when collapse is to the function liked in file, the first mark is permissibleIt is filename and function name, it is also possible to be the first cryptographic Hash calculated according to filename and calculate according to function name secondCryptographic Hash, the present embodiment is not construed as limiting.
Specifically, from exception stack information, extract the first mark of each collapse object, including: read exception stack letterEvery stack information in breath, every stack information includes the n-layer information recorded in a storehouse of correspondence, and record in storehouseThe 0th layer of information be the information of collapse position object, in storehouse, the i+1 layer information of record is call i-th layer of object rightThe information of elephant, 0≤i≤n；For every stack information, in detection stack information, whether the object in jth layer information is that collapse is rightAs, when in jth layer information to as if during collapse object, read the first mark of object in jth layer information；When jth layer is believedWhen object in breath is not collapse object, j is updated to j+1, continues executing with the object in jth layer information in detection stack informationWhether it is the step collapsing object, 0≤j≤n.
As a example by stack information in step 201, #00 record is the 0th layer of information, and #01 record is the 1st layer of information,The like, #07 record is the 7th layer of information.Wherein, in example, one layer of information can include terminal type, memory address,File and function side-play amount hereof.Certainly, every layer of information can also include other information such as function, function parameter,The present embodiment is not construed as limiting.
Call relation is there is in stack information, i.e. i+1 layer information between i+1 layer object and i-th layer of object of recordIt is the information of the object calling i-th layer of object.
Such as, stack information have recorded 4 layers of information, respectively the 0th layer information, the 1st layer of information, the 2nd layer of information and the 3rd layerInformation.1st layer of information is the information of the object that have invoked the 0th layer of object, and the 2nd layer of information is to have invoked the object of the 1st layer of objectInformation, the 3rd layer of information is the information of the object that have invoked the 2nd layer of object.
When stack information is analyzed by server, first whether the object in the 0th layer of information of detection is collapse object, ifIn 0th layer of information to as if collapse object, then read this collapse object first mark, terminate analysis process；If the 0th layer of letterObject in breath is not collapse object, then whether the object in the 1st layer of information of detection is collapse object, if in the 1st layer of informationTo liking collapse object, then read the first mark of this collapse object, terminate analysis process；If the object in the 1st layer of information is notBe collapse object, then whether the object in the 2nd layer of information of detection is collapse object, and the rest may be inferred, until collapse object being detectedTill.
Wherein, whether when detecting object and being collapse object, server can detect whether object is to get specificallyThe object of code；When to as if when can get the object of specific code, determine this to as if collapse object；When object is notThe function of specific code can be got, such as, during to the function liked in function library, determine that this object is not collapse object.
During reality realizes, owing to the numerical value of i is the biggest, the object of i-th layer of object reference is the most, now, analyzes i-thThe reason of layer object collapse is the most complicated, and therefore, generally, server only analyzes the 0th layer of object and the 1st layer of object.
Step 2032, extracts the second mark of each exception object from the first abnormality code information.
Second mark is used for indicating exception object.Such as, when function during exception object is file, the second mark is permissibleIt is filename and function name, it is also possible to be the first cryptographic Hash calculated according to filename and calculate according to function name secondCryptographic Hash, the present embodiment is not construed as limiting.
Step 2033, when there is the first mark and the second mark that match, by right for the exception indicated by the second markAs being defined as the exception object associated by the collapse object indicated by the first mark.
With the second mark coupling, first mark refers to that the first mark is identical with the second mark, or, the Hash of the first markIt is worth identical with the cryptographic Hash of the second mark.Such as, the first mark is OnMoveNext (), and the second mark is OnMoveNext (),Then server determines that the first mark and the second mark match.
With the first mark and the second mark, the present embodiment all includes that filename and function name are to coupling the first mark and secondThe process of mark illustrates, and it is the most identical, at literary composition with the filename in the second mark that server can first detect the first markThe while of part famous prime minister, then it is the most identical with the function name in the second mark to detect the first mark, when function name is identical, determines firstMark and the second mark match.
Step 204, positions the position in code of the exception object associated by each collapse object.
Owing to exception object line number in code determines that, therefore, the exception associated by collapse object is being determinedAfter object, developer can be directly targeted to the code indicated by this line number, modifies this code, right to repair collapseAs.
Owing to server may orient the position in code of the exception object associated by multiple collapse object, and serviceDevice is probably repairs collapse object according to tab order prompting developer, and now, collapse object is entered by developer successivelyRow is repaired.Owing to the number of users of some collapse object influences is many, the number of users of some collapse object influences is few, therefore, and serverAccording to the number of users that collapse object is affected, collapse object can also be ranked up, to point out developer preferentially to repair impactThe collapse object that number of users is many, to ensure that most of user can normally use project, now performs step 205.
Step 205, for each collapse object, obtains the quantity of the terminal reporting collapse object.
Wherein, the quantity reporting the terminal of collapse object is the number of users of collapse object influences.
Step 206, according to the order that the quantity of the terminal reported is descending, is ranked up each collapse object.
Step 207, shows that the first information, the first information are used for pointing out the preferential reparation preceding collapse of sequence rightAs.
In one implementation, server can from the quantity of sequence the selected and sorted quantity in front n position, and generateFor indicating the first information of collapse object corresponding to every kind of quantity.Wherein, n is positive integer, and such as, n is 10,50,100Etc..
Such as, the quantity reporting the terminal of collapse object 1 is 500, and the quantity reporting the terminal of collapse object 2 is 1500,The quantity reporting the terminal of collapse object 3 is 2500, and the quantity reporting the terminal of collapse object 4 is 2000, and n is 2, then serviceDevice generates for indicating collapse object 3 and the first information of collapse object 4.
In the present embodiment, server can also there may be in project according to the exception object associated by collapse objectCollapse object be predicted, with reduce collapse probability of happening, improve code quality.Now, each collapse object is being positionedAfter associated exception object position in code, also include: obtain what the code to sundry item was scanned obtainingSecond abnormality code information, to there is each of code error in the code of sundry item different for indicating for the second abnormality code informationOften object；The second incidence relation according to the collapse object determined in project with exception object, it was predicted that will in each exception objectCause the exception object of collapse；Show the second information, for pointing out to repair, the second information predicts that the exception obtained is rightAs.
Such as, collapsing object 1 and associate with exception object 1 in project 1, now, the second incidence relation includes collapsing object 1With the incidence relation of exception object 1, then, after determining exception object 1 in project 2, server can be according to the second incidence relationDoping exception object 1 and may cause collapse, and the object of collapse is probably collapse object 1, now, server prompts is developedCollapse object 1 is repaired by personnel.
Certainly, server can also extract the general character between each exception object causing collapse, when from sundry itemWhen scanning the exception object with general character, then predict that this has the collapse object of the exception object of general character association, pre-to improveThe accuracy surveyed.
In the present embodiment, refer to Fig. 6, server can include bugly server, TSC match server, and TSC scansServer, TSC web page server, and TSC match server respectively with bugly server, TSC scanning server, TSC webpage clothesBusiness device is connected.Wherein, bugly server is the background server of bugly platform, and bugly platform is the different of reception terminal to reportThe often platform of stack information, TSC scanning server is the background server of TSC scanning platform, and TSC scanning platform is to useTscanCode (code scans instrument) is scanned the platform of the first abnormality code information that obtains to item destination code, and TSC matesServer is the server mating exception object information and the first abnormality code information, TSC web page server be forShow the server of the association of collapse object and exception object.
Refer to Fig. 7, it illustrates a kind of schematic diagram that collapse object associates with exception object, wherein, aobvious in region 701Show is collapse object, is shown that collapsing the exception object of object association in region 702.
