Description
Technical Field
The invention relates to the field of computers, in particular to a method and a device for classifying and counting iOS (iOS Operation System) crash data.
Background
Currently, apps running on the iOS system usually report stack information, device information, etc. when a crash occurs to a server after the crash occurs (commonly referred to as "application flash back"), some of the apps are completed by official crash collection of applets, and more apps are selected to collect data by using third-party crash collection analysts such as member union, Tencent Bugly, etc.
However, after receiving a large amount of crash data (assuming that a piece of crash data is placed in a text file separately), how to classify the crash files, how to effectively define which crash files belong to the same bug (hidden undetected defects or problems in a system or a program, which are causes of a crash), and how to perform statistical analysis on the crash files so as to better improve the stability of the app.
In the uploaded crash information, the contents of the third-party crash SDK, the crash collection SDK developed by the large company and the crash collection collected by the apple company are very different, but the third-party crash SDK, the crash collection SDK and the crash collection SDK have the following data: crash occurrence time, app version and build number, system version, device type, start time, error type, crash thread call stack information, etc. In the present invention, for the purpose of pursuing versatility, only the original data is limited to the above items.
Most of the prior arts only simply call statement matching at the top of the stack according to the crash thread or completely matching the crash stack as the basis of crash classification. There is no systematic complete solution to achieve accurate classification. Specifically, the method comprises the following steps:
first, a large number of crash logs are obtained, each crash log being a file.
Then, call stack symbolization is performed on all crash logs using symbolocatescah.
Next, a sort operation is performed on the crash files.
And finally, directly extracting the calling statements of the calling stack top for comparison, and if the calling statements of the stack top function are consistent, classifying the function as the same type of crash.
Since the stack top calling statement is the last executed place of the program and is also the statement of the crash, the crash is classified roughly and shallowly directly according to the stack top statement.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:
since the prior art directly classifies crashes according to the stack top calling statement, the crash causes inaccurate positioning in some cases, because the crash is not necessarily caused by calling the stack top layer code, but is triggered by a middle certain statement call, and what we really need to position is the call that the crash is caused by the statement. For example, there is an abort () statement in the program, which indicates that the developer wants to actively throw an exception and terminate the application, and this statement is commonly used in the system library, and when a system function is called, if a call error or a parameter mismatch is found, the system may call this statement and terminate the application, and at this time, the call stack top statement is abort (). However, the cause of the crash is that the system function is called incorrectly, for example, parameters are wrong, environment configuration is wrong, and the cause of the crash should be located in the statement calling the system function, instead of the statement abort (), and the cause of the crash is that firstly, the system function is uncontrollable, and if an exception occurs, the crash can be repaired only by modifying its calling mode or replacing the calling statement; secondly, many system functions eventually call abort () to terminate applications, and the reason for triggering them is caused by calling mode errors/parameter configuration errors, and what should be found is the real reason for triggering abort, not the statement that triggers crash, abort ().
The classification of the existing scheme can cause that a plurality of real crash reasons are hidden under the same crash, and the classification is not thorough. As just noted, there are a number of reasons why an abort statement may result in the application last calling abort () for which the reason should be classified rather than against the statement.

Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
FIG. 1 is a block diagram of a system for implementing crash data classification and statistics, according to an embodiment of the invention.
Referring to FIG. 1, the system includes a preliminary classification module, a recursive classification module, and a report generation module. Each module will be described in detail below.
A preliminary classification module: and the system is responsible for carrying out classification statistics on the crashes which can be classified fully automatically at the place, mainly comprising the crashes (except for main statements) in which code calling statements definitely exist in a calling stack, classifying the crashes at the place and outputting a primary classification report.
A recursive classification module: and continuously iterating and classifying the unclassified crash data through the written configuration file, continuously reducing the unclassified crash proportion, and outputting a recursion classification report form after each iteration.
A report generation module: and integrating and outputting the primary classification report and the recursive classification report, and outputting a final report of the crash analysis in combination with a final report of the last crash analysis.
The pre-operation required for realizing the invention is as follows:
using crashsign translation tools such as ats, Symbolic technology, etc., requires first translating the binary address of the call stack into a visual call statement.
FIG. 2 is a detailed flow diagram of the preliminary classification module according to an embodiment of the present invention.
Referring to fig. 2, the detailed flow of the preliminary classification module is as follows.
First, data is entered, which is the original set of crash data files.
Secondly, invalid data is filtered: invalid crash data is filtered first, and by formatting each crash file into an object, which crash data is not in accordance with the analysis requirements can be effectively checked. For example, the file information is incomplete, the app version not targeted by this analysis crashes, and the like. In addition, other field-specific filter checks may also be performed herein. For example, if a user wishes to analyze only crashes for a particular iOS system version, the program may be expanded at this point, with unspecified versions of crashes being filtered out.
Thirdly, classifying App crash statements: in the step, a crash call stack is read at first, the call stack of the crash thread is traced back, the call stack is searched downwards from the topmost layer, whether a call statement belonging to the own app exists or not is checked, and a regular expression is used for checking whether the call statement conforms to the specification or not. If the statement exists, the statement is extracted to serve as a crash occurrence reason, the class name, the function name and the file function of the statement are extracted to serve as the description of the crash reason, a mapping table for the crash reason and a storage folder is made, and crash data of the same crash reason is placed under the same folder.
An example crash log call stack is given below.
The name of the crash call function (in Jsubpad) is represented in the call stack statement [ JDInviceInfoView controller fillVatInviceView: ]; indicating to which library the calling function belongs; (JDInvocicInfoViewController. m:2106) indicates to which file the calling function belongs. Therefore, it is known from the library name that it is the invocation statement belonging to the app itself, not the system library invocation.

Fourthly, outputting the result: after the previous steps are completed, outputting a preliminary classification report, wherein the report is a list, the content of each item comprises classified collapse reasons, proportion statistics and folder positions where collapse types are stored, and the classified collapse reasons, the proportion statistics and the folder positions are sorted and output according to the proportion.
After the above steps are completed, the data that has not been filtered or classified is placed in the unclassified folder and indicates the fraction of unclassified crashes, waiting for the recursive matching state to be entered.
FIG. 3 is a detailed flow diagram of the recursive classification module according to an embodiment of the invention.
The detailed flow of the recursive classification module is described below with reference to fig. 3.
The detailed flow of the recursive classification module is as follows:
1. inputting data: and after the preliminary classification is completed, the set of unclassified crash files.
2. Generating a matching rule object list: reading in a configuration file (written by json), converting the configuration file into an object, converting each matching rule into a matching object, forming a matching object list, and delivering the matching object list to a matching manager for management. The basic function of each matching object is to perform regular matching according to the specific field of the configuration, and further support multiple fields and matching and multiple or matching.
3. And circularly reading the crash data, continuously reading the crash data which is not processed, submitting the crash data to a matching manager for matching, and classifying the crash data into a crash folder mapped by a specific matching rule if the crash data can be matched with the specific matching rule. If none match, then put into the unclassified folder.
4. And outputting a result: and after all input data are processed, outputting a result report matched at this time, outputting a report classified by recursion, wherein the report is a list, the content of each item comprises the classified collapse reason, the proportion statistics and the position of a folder stored by the collapse type, and sequencing and outputting according to the proportion. While data that is not filtered or classified is placed in the unclassified folder and indicates the proportion of unclassified crashes.
The following detailed description is made with respect to the way in which the configuration file is written:
1. first, it needs to analyze the crash under the unclassified folder, and after reading a crash file, it will classify the cause of the crash and some identification fields in its crash report indicating its cause.
2. The configuration file itself is a text file in json format and the outermost layer is a list. Each item in the list includes a description of the cause of the crash, a field of crash cause matching rules (supporting regular matching, and supporting the same rule to take effect together to match, and any matching of multiple rules to match). The crash information summarized above is converted into a crash matching rule in the configuration file.
3. The matching rules will now be described in detail: each crash matching item of the json file is a dictionary, each dictionary has a keyword key value and a keyword list key value which respectively correspond to an array, each item in the array is a regular expression character string, all expressions in the keyword array must be satisfied, and at least one expression in the keyword list array must be satisfied. In the call stack of the crash log, each row of call statements is taken as a unit, the search is respectively carried out with the regular expression, and if any call statement in the call stack can search the content of the regular expression, the regular expression is satisfied. In addition, there are some common fields, such as iOSVersionMin and iOSVersionMax, used to indicate the range of system versions that need to be matched; such as exceptinontype, to indicate which type of Exception (a system-supplied value, such as NSGenericException, NSRangeException, NSInvalidArgumentException, …) is specific; for example, signalType, to indicate which type of signal is triggered (system supplied values, such as SEGV, SIGBUS, SIGABRT, …); for these common field matching items, it is only necessary to write "NULL" directly without participating in matching.
4. The reason why this matching table can help classify crashes will be described in detail. Because of the crash due to the same kind of reason, it must be embodied in the call stack. For example, a crash caused by a system cause, the system version of the crash is very concentrated, and then, although the whole call stack may be different, some call statements inside the call stack are overlapped, and these statements are the cause that we think of triggering the crash and are the common characteristics of the call statements. Therefore, after an experienced developer sees crash logs that cannot be automatically classified, some common characteristics can be extracted from the crash logs, and then the crash logs are sequentially configured according to the provided configuration items, so that further classification can be performed on unclassified crash logs.
As a crash reason generally corresponds to a plurality of crash files, the unclassified crash is continuously read, then the configuration file is updated, and then the recursive classification module is executed, so that the unclassified crash files can be reduced once and again. When the unclassified crash data proportion is considered to be in a reasonable position through iteration, the final report can be integrated and output.
The report generation module will be described in detail below:
1. and combining the previous preliminary classification report and the recursive classification report, and outputting a combined report. The report content is divided into two parts:
a) overview of the results: the method comprises the total number and the proportion of the legal breakdown, the classified number and the proportion of the breakdown in the primary classification stage, the classified number and the proportion of the breakdown in the recursive classification stage and the number and the proportion of the breakdown without classification.
b) Crash statistics list: each item of content includes a crash cause, a number of crashes caused by the crash cause, a duty cycle, and a folder location where the crash type is stored. And the entire list is sorted by duty from high to low.
2. Optionally, if the analysis report of the last crash can be read, the crash merged report of this time and the analysis report of the last crash are compared. And (3) performing trend description on the crash proportion of the same reason in the crash statistic lists of the two reports, and directly adding a field to the content item of the crash reason in the crash statistic list to indicate the trend: "new increase" represents that the cause of the crash is a classification newly generated after the crash analysis, "+ xx.xx%" indicates that the proportion of the crash is increased compared to the previous analysis, and further attention needs to be developed, and "— xx.xx%" indicates that the proportion of the crash is decreased compared to the previous analysis.
After the first two steps are completed, the output report is the final crash analysis report.
In the following, the complete classification flow will be described:
1. the crash files are all placed in a specific folder first, and then the preliminary classification script is executed. The crash file at this time must be a file that has undergone symbolization operations, and all call stacks thereof must be visualized code call statements, not binary addresses.
2. A primary classification stage: firstly, all crash logs are checked, and crash logs (format requirements and the like, and users can perform custom expansion) which do not meet requirements are directly deleted. Then, the call stack of each file is searched from the top of the stack to the bottom of the stack, and a first calling statement of the non-system library calling and non-main functions in the stack is found and used as a classification basis for the crash. The crashes that extract the same calling statement need to be classified into one category and stored in the same folder. Finally, the crash which cannot be classified in the above mode is placed in an unclassified folder, and the category of the classification and the proportion of each category are output (the unclassified category also counts as one category).
3. And checking the crash of the unclassified folder, and writing the configuration file according to the [ writing mode of the configuration file ].
4. And executing a recursive classification script, acquiring initial data from the unclassified folder after the last step of preliminary classification, sequentially matching each crash file with each matching table configuration through the written configuration file, classifying the crash log into a crash classification corresponding to the configuration item if the matching is successful, and moving the crash log into a specific classification folder from the unclassified folder (if the classification folder does not exist before, the crash log is newly built and moved into the specific classification folder). And finally, outputting the recursively classified categories and the proportion of each category (the unclassified category also serves as one category).
5. And (4) continuously executing (3) and (4), and integrating and outputting a final report when the crash data ratio under the unclassified folder is in a reasonable position through iteration.
6. And (4) putting the last analysis report result in the current folder, and executing the report generation script to obtain a final crash analysis report.
