Technical Field

Background
In general, a method for clearing a large number of accumulated compiled alarms in a code library is to divide codes to special persons according to modules for elimination. That is, code files of different modules in a large code library are usually maintained by different project groups, compilation alarms in each code file can be given to one or a plurality of people in the corresponding project group, and the concentrated time is eliminated uniformly. The version control tool can also be utilized to track the history of the alarm introduction, firstly, the line of the alarm is determined, the reason of the alarm is clarified, and then, the developer who submits the relevant code is found through the code submitting history recorded in the version control tool, namely, the developer is arranged to eliminate the compiled alarm.
The main disadvantage of eliminating compiled alarms by a dedicated person is that the compiled alarms to be eliminated by the person are often not introduced by himself, and when related alarms are eliminated, the alarms are often eliminated only for eliminating the alarms, and regardless of the history reasons of introducing the alarms, an erroneous elimination method may be used. If the code submitting history is firstly searched, the responsible person introducing the compiling alarm is found, and then the corresponding responsible person is arranged to eliminate the compiling alarm, the probability of correctly eliminating the alarm is higher, but the defect is that a great amount of energy is consumed in the searching process, and the execution efficiency is not ideal.

FIG. 1 is a flowchart illustrating a method of compiling alert tracing according to an exemplary embodiment. The compiling alert tracing method 10 at least includes steps S102 to S112.
As shown in fig. 1, in S102, a plurality of alarm problems are acquired by parsing alarm information of a code base. Taking SVN as an example, the tool records the content and responsible person of the file that the SVN client (SVN local library) submits to the SVN server each time, and the SVN version number increases by 1 when the submission is successful. If the file managed by the SVN server is a text file (including a source code file), each historical version of the file can be queried with a SVN log command, text differences between any two historical versions can be queried with a SVN diff command, and the responsible person and version number specifying the current version of the file or each line modification of the historical version can be viewed with a SVN name command.
In S104, a plurality of source files of the plurality of alarm problems and a plurality of commit records corresponding thereto are acquired based on an operation instruction of a user. May include: acquiring a plurality of source files of the plurality of alarm problems based on an operation instruction of a user; acquiring a plurality of header files contained in the plurality of source files; and acquiring a plurality of commit records from the plurality of header files based on SVN log technology.
In S106, a target source file is determined from the plurality of source files. Multiple source files can be read one by one and processed sequentially.
In S108, the header files having the same alarm problems as the target source file are assembled into an alarm problem set.
In S110, a similarity between the target source file and each source file in the alert set is determined. Comprising the following steps: acquiring first contents of a plurality of lines before and after a line where an alarm problem corresponding to each source file in the alarm set exists; acquiring second contents of a plurality of rows before and after the alarm problem corresponding to the target source file; and carrying out similarity calculation on the first content and the second content.
In S112, alert traceability information of the target source file is generated based on the similarity and the plurality of commit records. Comprising the following steps: and when the similarity is larger than a threshold value, determining an initial version of the alarm problem corresponding to the target source file based on the submitting record, and generating the alarm tracing information. Further comprises: and when the similarity is smaller than or equal to a threshold value, determining that the version of the alarm problem corresponding to the target source file is the later version of the preset version based on the submitting record, and generating the alarm tracing information through the preset tracing information.
More specifically, the initial version of the alarm problem corresponding to the target source file is determined to be the earliest version based on the submission record; or determining that the initial version of the alarm problem corresponding to the target source file is the later version of the preset version based on the submitting record.
According to the compiling alarm tracing method disclosed by the invention, most compiling alarms existing in the code library in the project warehouse can be traced back to accurate introduction responsible persons, and part of special compiling alarms can determine module responsible persons, so that the efficiency of compiling alarm tracing can be greatly improved, and the mishandling phenomenon caused by inconsistency of the responsible persons due to the introduction of the alarms is reduced.
It should be clearly understood that this disclosure describes how to make and use particular examples, but the principles of this disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
In one embodiment, before the analyzing the alarm information of the code base to obtain the plurality of alarm problems, the method further includes: and determining the analysis mode of the compiler and the SVN tool on the line change mark.
In the prior art, the line number of the alarms reported by the compiler and the line number seen by other tools looking at the code file may be different, as the interpretation of the line feed by different tool software may be different. For example, for three line feed labels, namely, an individual carriage return r (which means that r is not immediately followed by n), an individual line feed r n, and r n, in combination, some tool software is approved as a line feed, and some tool software is only partially approved, so that the line number of the compiled alert prompt is not necessarily consistent with the line number displayed by various text viewing/editing tools. In this case, the compiled alert line number prompted by the compiler may not be consistent with the line number in the result output by the svn frame command, and the line number understood by the text viewing/editing tool may not be consistent. Therefore, there is a need to determine the manner in which the compiler, the svn tool, and the text viewing/editing tool used in the present solution interpret the line marking.
For the determination of the line feed flag of the compiler, the method may be: a source code file is constructed, four alarm sentences with different alarm contents are constructed (taking C language as an example, a compiler can prompt alarm information xxx by using the statement of "# warning" xxx "), and the four alarm sentences are sequentially separated by \r\r\n, \n and \r\n (separate \r and \n post-adding \r\n are used for ensuring that front and back contents are separated into two rows, because \r\n is taken as a real line-feed mark by using a compiler or any text viewing/editing tool). And adding the file to a code module directory, compiling the module, and checking the line of the compiling alarm prompt generated for the file. Since the file does not contain anything other than the alarm, the compiling result of the original module is not disturbed. Assuming that compiler considers individual\r to be a line feed flag, compiling 2 nd alarm generated by the file should report on line 4, otherwise should report on line 3; and others alike. Thus, the resolution mode of the compiler on the line change marks is determined.
For the determination of the line feed mark of the svn tool, the method may be: any one file is found in the local SVN code base, and the following character strings are inserted at the beginning of the file: a\r\nb\n\nc\r\nd. Then execute the svn diff command to the file to check the output result. The svn diff will be preceded by a "+" sign for each newly added row, thus: if there are two "+" between a and b, it is stated that an individual \r will be interpreted by the svn tool as a wrap mark, and if there is only one "+" it is stated that an individual \r will not be interpreted by the svn tool as a wrap mark. b and c, it can be determined whether the individual \n is interpreted by the svn tool as a wrap-mark. After analysis, the svn reverse command is used for returning the modification to the file.
In the embodiment of the disclosure, if the line feed mark type supported by the compiler is the same as that of the svn tool, the line number of the same file is understood to be the same, and no special processing is needed; otherwise, a file line number mapping table needs to be established for the related code file, so that the compiler and the svn tool can mutually convert the line numbers of the same file. The file line number mapping table splits the union of line feed marks of both sides of the file content into a plurality of lines, each line being marked with a line number considered by two tools for the corresponding line content.
When the compiler reports that the 1 st line of the file has a compiling alarm, the 1 st line and the 2 nd line of the execution output result of the svn frame should be checked and respectively modified (the character string c should be irrelevant to the alarm, but the svn frame cannot distinguish the character string b); when the compiler reports that the 2 nd line of the file has compiling alarm, checking who modifies the 2 nd line of the svn frame executing output result; when the compiler reports that line 3 of the file has a compilation alarm, it should be checked by whom line 3 of the svn frame execution output was modified.
Note that for a file in the SVN library, different versions of the file line number mapping table are required, because the updated content changes, and the line number mapping relationship may also change.
If the understanding of the line number is different between the compiler and the svn tool in a certain compiling environment, but if the line numbers in the file line number mapping table are in one-to-one correspondence for a specific file, the fact that the line numbers are not separated in the file is indicated, that is, the file line number mapping table is not needed, and the file is marked with a 'no need of line number conversion'.
1. The latest version code file in the project library is signed out from the SVN server, the current SVN version number v is recorded, compiling operation is carried out, and all output information (comprising normal compiling information and alarm information) is stored in a file common_results.v.log (v is a positive integer).
2. For the content of the file combole_results.v. log, the line where the word "warning:" exists (the string is the line where the compiler marks the compiled alarm) is found line by line.
Compiling alarms is various, and partially compiling alarms and code lines is not a simple one-to-one correspondence. Some compiled alarms may be introduced by one of a plurality of code lines, each line having the same suspicion; it is common that two compiled alarms correspond to the same problem. Taking the compiled alarm for prompting macro to repeatedly define as an example for explanation:
In file included from a.h:28,
from b.h:6,
from c.c:24:
d.h:414:1:warning:"HAVE_XXXX"redefined
In file included from c.c:9:
e.h:182:1:warning:this is the location of the previous definition
The above example illustrates c.c containing b.h, b.h containing a.h, a.h containing d.h, d.h, line 414 defining a have_xxx macro; meanwhile, the line 182 of e.h included in c.c also defines the macro, but the values of the macro and the macro are different, so that the macro is reported to repeatedly define the compiled alarm when the macro is compiled c.c. This may be due to two macros of different meaning but of the same name appearing in the same source file (the header file contained by the source file corresponds to a portion of the source file), which may occur for two reasons:
1) A macro is newly added in codes submitted by a developer or the name of an existing macro is modified to be the same as the name of the existing macro, the values of the macro and the name of the existing macro are different, and the macro and the name of the existing macro are in the same source file;
2) Originally, two macros with identical definitions are contained in the same source file, and no alarm is given in the situation; later one of the macro definitions is modified, resulting in an alarm;
3) Two macros of the same name have been previously included in the same source file (e.g., they are defined in two header files that are not included by the same source file), and now the developer has modified the header file inclusion relationship (e.g., c.c did not originally include e.h, and now included e.h; or a.h does not contain d.h and is now modified to contain d.h; etc.), resulting in two macros appearing in the same source file.
From the above analysis, it can be seen that each of the above locations (e.g., line a.h, line b.h, line 6, line c.c, line 9, etc.) where the relationship occurs may be where an alarm is introduced, and the exact location is determined by searching for the line in a.h where "# include" and "d.h" exist, the line in b.h where "# include" and "a.h" exist, and the line in c.c where "# include" and "b.h" substrings exist; and defining the location of the macro (e.g., line 414 of d.h, line 182 of e.h) may also be where the alert is introduced, the exact line number of the "have_xxxx" occurrence in both files should be searched. All the above positions need to be checked for commit records.
Therefore, for compiling alarms, it is not possible to simply process the alarms one by one, but rather to process the alarms in case of cases in combination with specific compiling alarm types. If the alarm is really corresponding to one code line, the code line can be simply subjected to a tracing operation; if the alarms aim at the same problem of the same line, combining the alarms, and performing only one-time tracing operation; if a plurality of code lines can possibly introduce the alarm, the tracing operation is respectively carried out on the code lines, and the results are summarized together. For this reason, all alarm problems are numbered, and for alarm problems with specific numbers, there are corresponding alarm contents, several groups of < files, line numbers >. One group of these < file, line number > information is always the source file, and the other is the header file.
In one embodiment, further comprising: acquiring a current code version number based on the alarm information; determining a preset version number based on the current code version number; and generating preset traceability information based on the preset version number. More specifically, it is possible, for example: determining a target alarm problem corresponding to a target source file; updating the code library to the preset version number; and generating the preset traceability information by compiling a minimum range code file containing the target alarm problem. With the binary compilation method, the time complexity of the compilation times is O (lg (n)), and the time complexity of the version-by-version compilation is O (n), so that the binary compilation method can greatly save the compilation times compared with the version-by-version compilation. In addition, because there may be multiple alarms in one source file, the log file of a.versions [ mid ]. Generated when tracing one of the alarms can also be used in the tracing process of other alarms, i.e. if the code of a version number of a certain module has been compiled, the compiling result file generated before can be reused. Therefore, when the source file containing m alarms and n submitted records is traced to the m alarms, the compiling times do not exceed n, namely, a smaller value is taken between n and m x lg2 (n).
In one embodiment, further comprising: and carrying out format arrangement on the alarm problems based on the operation instruction of the user to generate a plurality of file information. And acquiring alarm tracing information of the plurality of file information through SVN name technology. For specific steps, reference may be made to the corresponding embodiment of fig. 2. The flow shown in FIG. 2 may be a "fast mode" in which the following may be handled for each alarm problem one by one:
as shown in fig. 2, in S201, relevant information of an alarm problem to be processed is acquired.
In S202, whether the compiler and the SVN tool have the same line feed parsing scheme.
In S203, the < file, line number > in the alarm problem is directly used as the < file, line number > corresponding to the SVN tool.
In S204, a mapping table of file line numbers of the related code file is generated, and mapping tables corresponding to two groups of line numbers one by one are deleted, and the corresponding file is marked as "no line number mapping is needed".
In S205, < file, line number > in the alarm problem is converted into < file, line number > corresponding to the SVN tool.
In S206, an SVN name command is executed for each code file related to the present alarm, and the corresponding row is found by using the above < file, row number > information corresponding to the SVN tool, so as to find the corresponding responsible person.
In S207, a tracing result is generated, which includes an alarm number, alarm content, and a plurality of sets of < file, line number, code line content, responsible person > information.
In S208, whether there is still an alarm problem to be processed.
In S209, the tracing result is output.
(1) If the compiler and the svn tool are consistent in the analysis mode of the line changing mark, a mark which does not need a line number mapping table of the file is added to the file related to the alarm problem; otherwise, generating a file line number mapping table for the related file. If two groups of line numbers in the line number mapping table of a certain file are in complete one-to-one correspondence (namely, line changing marks identified by only one party do not exist in the file), the line number mapping table of the file is deleted, and a mark of 'no line number mapping table of the file' is also made on the file.
(2) The line numbers in the < file, line number > group in the alarm problem information are translated into line numbers corresponding to the svn tool: traversing each file, and if the file has a corresponding file line number mapping table, converting the line number reported by the compiler into a line number corresponding to the svn tool by using the mapping table; otherwise, no conversion is needed, and the two line numbers are equal.
Checking the file by using a svn frame, and determining a modifier of the corresponding row as a responsible person according to the converted < file, row number > group information; if the line does not find a modifier other than the SVN library administrator (e.g., the code library is a branch in the SVN control tree, and some historical versions of the branch are merged by the SVN library administrator from other branches, the branch loses its commit record, only merged historical modification records can be found from the present branch, and the historical modification records on other branches cannot be found), then the human responsibility for recently modifying the file is assumed; if no one ever changes from the historical version that this file can look up, the responsible person is displayed as unknown.
FIG. 3 is a flowchart illustrating a method of compiling alert tracing according to another exemplary embodiment. The flow as shown in fig. 3 may be an "advanced mode" in which the following may be handled individually for each alarm problem:
as shown in fig. 3, in S301, relevant information of an alarm problem to be processed is acquired.
In S302, a corresponding.d file is obtained from the source file in the alert problem, from which a header file is obtained. And executing SVN log command to obtain submitted records on the source file and the header file, arranging from small to large, storing version information into a versions array, and taking min=0 and max=the number of versions elements-1.
In S303, mid= (min+max)/2 is rounded, the code library is updated to Versions [ mid ] by the SVN update command, the minimum range code file including the source file corresponding to the warning is compiled, and the compiling result is stored in a.versions [ mid ]. Log.
In S304, the second alarm information, which is the same as the present alarm problem, in the source file is extracted, and the number of pieces of alarm information is recorded.
In S305, the number of bars >0? .
In S306, for each piece of the second alarm information of the version, the < file, line number > is converted into the < file, line number > information corresponding to the SVN tool, the content of the plurality of lines before and after the alarm line is obtained, text similarity detection is performed on the content of the plurality of lines before and after the alarm line, and the text similarity is calculated with the version-related code of the line number of the latest confirmed alarm in the larger version. And recording the code line number and the similarity value of one alarm with the highest similarity value.
In S307, it is considered that there is no alarm in this version, let min=mid+1.
In S308, whether the highest similarity is higher than a threshold.
In S309, the alarm is considered to exist in the version, and the code line number corresponding to the alarm is recorded, and max=mid-1.
In S310, min > max? .
In S311, it is determined that the version in which the alert is introduced is Versions [ mid+1].
In S312, max <0.
In S313, it is determined that the version in which the alert was introduced is earlier than the earliest version.
In S314, min > max? .
In S315, the version in which the alert was introduced is determined to be Versions mid.
In S316, a tracing result is generated, which includes an alarm number, alarm content and incoming version number, and responsible person information.
In S317, whether there is still an alarm problem to be processed.
In S318, the tracing result is output.
A line of code may be modified multiple times, and in most cases, if a line of code has a compilation alarm, the last modification will be done most of the time. Even if the incoming alarms are not modified the last time, the developer's role in the line code should in principle be fully understood, so that the elimination of the alarms by the developer is much more reliable than the random arrangement of a developer to eliminate the alarms. Therefore, it is generally reasonable to take the responsible person who submitted the code of a certain line for the last time as the responsible person who eliminates the compiled alarm reported by the code of the line. The svn frame can be executed for the file with the alarm, and the responsible person who modifies the code line corresponding to the alarm last time is determined as the alarm responsible person.
But in a few cases the compilation alarm may be introduced by the earliest version of the modification, or the compilation alarm may not be a problem for the code line it indicates. Such as: a certain line of code invokes a certain macro, and no alarm is introduced; the definition of the macro is modified later, and the code in the macro definition has an alarm, and the compiled alarm is reported on the code line for calling the macro. In this case, tracing the alarm responsibilities for the row to which the alarm refers is inaccurate. The macro definition and the macro reference may belong to different modules and different project groups, and it is not necessarily appropriate for a responsible person who calls the macro to process the compiled alarm in the macro definition. Thus, if possible, the actual introduction of the alarm should be as accurate as possible.
In order to more accurately find the corresponding responsible person, the responsible person introducing the alarm can be traced back by a binary compiling method. The method has the advantages that the trace-back introduction responsible person is more accurate, but the execution time is longer (depending on the compiling times and the code quantity of the module for executing the compiling), and the method is suitable for the scene of intensively processing the compiling alarm in a large batch under the condition of sufficient time. The specific scheme is as follows:
(1) And obtaining the.c file corresponding to the current alarm and all header files contained in the.c file through compiling the generated intermediate file.d file (the.d file lists the.h file directly or indirectly contained in the current.c file).
(2) And acquiring the submitted records of each file in the code base through a SVN log < file > command, and merging and arranging the files according to SVN version numbers from small to large. The commit records of a plurality of files with the same version number are combined into a strip. Version number information of the merge arrangement is exemplified as follows:
SVN version|file
100|xxx.c
102|yyy.h
103|yyy.h;xxx.c
108|zzz.h;xxx.c
……
(3) Since the alarm is introduced at a certain version number N, the code corresponding to the version number earlier than N does not exist the alarm, and the code corresponding to the version number later than N does exist the alarm (for the alarm already existing when creating the item, it can be understood that N is smaller than the version number of the code library that is the smallest). The version of the alert introduced is determined using binary coding:
1) Version number information of the merging arrangement is stored in one array version, wherein the minimum value of the array element number is min=0, and the maximum value is max=the element number-1. The number of elements is the number of the version number information.
2) Let mid= (min+max)/2 be an integer part, take version [ mid ] (i.e. version number of mid element of version array), update the project code library with SVN update command to SVN version number of version [ mid ], then compile the code file containing the minimum range of source file (in large project library, the minimum unit of compiling is typically a module, one module contains several source files), write the relevant information of source file in the compiled output information into a.version [ mid ]. Log (where a represents the file name of the source file, version [ mid ] refers to the current version number value, such as a.1999.log);
3) And analyzing A.versions [ mid ]. Log, searching for alarms which are the same as the contents of the compiled alarms being processed, and checking whether the compiled alarms still exist in the version. If so, it is stated that the alert was introduced at the latest in this version, so let max=mid-1, at which point: checking if max <0, indicating that the earliest version has the alarm, otherwise, if max < min, indicating that all the alarms are checked, introducing the alarm by version of versions [ mid ], otherwise, jumping to the step (2) to carry out next round of compiling and checking; if the version [ mid ] does not exist, the alarm is set to be min=mid+1, if min > max, the introduced version is determined to be version [ mid+1], otherwise, the next round of compiling checking is performed by jumping to the step (2).
The incoming version number of the alarm is found, and the incoming responsible person is also found.
How to check whether a particular alert still exists in a version: if it is directly checked whether there is an alarm of the same alarm content, there may be erroneous judgment: assuming that the file introduced an alarm in version 1, it was eliminated in version 2, and the same alarm was introduced in another row of version 3, to which the same file was not related. Then, when performing binary compilation tracing on the 2 nd alarm, the same alarm introduced by the version 1 may be mismatched (but not actually the same problem). To avoid such errors, it is necessary to check whether the code lines corresponding to the two alarms are logically identical. However, it is not reasonable to directly check whether the line numbers of the code lines corresponding to the two alarms in the two versions are consistent, because the version between the two versions may modify other contents of the file (adding or deleting a line in front of the line), so that the line number of the code line drifts, and it is difficult to ensure that the line number of a certain code line does not change among multiple versions; it is also unreasonable to determine if the code lines are identical in content because the version between them may modify other content of the line without affecting the existence of the alarm, and directly determining if the two code lines are identical in content may cause the alarm of the same line to be treated as two different alarms in different versions. For this reason, it is necessary to introduce text similarity checking techniques, namely: when a certain version of compiling result contains alarms which are the same as the alarms in the traceable mode, extracting all alarms of the same alarms in the version, and finding out the contents of the corresponding code line and the contents of a plurality of lines before and after the code line through file line number mapping (the method is the same as that used in the quick mode); finding the nearest version of the line number corresponding to the confirmed alarm in the larger version, and extracting the line and a plurality of lines before and after the line in the larger version; and checking the text similarity of the code texts corresponding to a plurality of alarms one by one with the code texts corresponding to the alarms, finding out one with the highest similarity, and if the similarity is higher than a certain threshold (proving that the two are the same code line), considering the two alarms as the same line and the two alarms as the same problem, and recording the line number corresponding to the alarm with the highest similarity. Otherwise, the current version is regarded as that no traceable alarm exists.
The tracing result is placed in a table file, and each row of the table contains alarm number, alarm content, file name, row number, code row content, responsible person name and other columns. For the case where one alarm is associated with multiple code lines, the alarm numbers of the lines are the same value, so that the operator can directly see that they belong to the same alarm.
