Description

Code detection method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a code detection method and device.

Background

Currently, many developers choose to develop their own extended operating system on the native code of the native operating system (e.g., android), such as the MIUI operating system developed by millet android-based native code, the emui (emulation User interface) operating system developed by china for android-based native code, and so on. These codes that extend the operating system may be referred to as extension codes, which are typically obtained by modifying native code based on the native code.

For example, as shown in fig. 1, a developer modifies a first code segment 101 in native code 11 into a second code segment 102 based on the native code 11 in android version 3.0, resulting in an extended code 12 of an extended operating system a. While the android version 3.0 based on the native code 11 will be upgraded irregularly, if the first code segment 101 is modified to the third code segment 103 in the process of upgrading the android version 4.0, a collision phenomenon occurs between the upgraded native code 11 and the extended code 12 at the position of the third code segment 103, and at this time, the extended operating system a is likely to be incompatible with the upgraded android version 4.0. Developers are required to perform a great deal of work such as code recombination and function reconstruction on the extension code 12 to support the upgraded android version 4.0.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

To clarify the explanation of a code detection method provided in the embodiments of the present application, some names that will appear in the embodiments will be explained first.

Native code, refers to the initial code of a native operating system (e.g., android, IOS, etc.) released by some native platform providers, e.g., android version 3.0 code, android version 4.0 code, etc., which is generally unmodified by third party developers.

The extended code refers to code of an extended operating system (e.g., hua ye EMUI, millet MIUI, etc.) obtained by modifying native code on the basis of the native code by a third party developer, for example, an Original Equipment Manufacturer (OEM) or a developer of application software, in order to implement some specific functions and services.

The modification of the native code may specifically include adding a new code field in the native code, deleting some fields in the native code, or modifying some fields in the native code, and the like, which is not limited in this embodiment of the application.

The conflict phenomenon is a phenomenon that after the extension code is upgraded, the extension code (obtained based on the native code before the upgrade) and the code of the native code after the upgrade are different at the same modification point.

The conflict phenomenon may increase the operation risk of the extension code, which may cause that the extension code may not support some new characteristics of the upgraded native code, and even the extension code may not normally operate on the upgraded native code. In this case, the developer needs to spend a lot of labor to perform the work such as code reorganization and function reconfiguration, which not only wastes labor but also affects the system stability of the entire extended operating system.

In this regard, an embodiment of the present application provides a code detection method, as shown in fig. 2, the method including:

201. the detection device obtains target native code and target extension code, the target extension code being derived based on the target native code.

The position of the target native code in the whole native code may be the same as the position of the target extended code in the whole extended code, for example, the target native code is 1-20 lines of page 3, and the target extended code developed based on the target native code is also 1-20 lines of page 3.

Alternatively, the target native code and the target extension code may also refer to a segment of code or function that implements the same function, for example, the target native code is a native code that implements a fingerprint unlocking function in android version 3.0, and the target extension code is an extension code that implements a fingerprint unlocking function in EMUI based on android version 3.0.

For example, the code detection method provided in the embodiment of the present application may be made into an application software, so that the detection device may complete the code detection method of steps 201 and 206 by running the application software.

For example, when a user starts a code detection function (e.g., starts running the application software), as shown in fig. 3, the detection device may display a setting interface 300, and the user (e.g., a developer of the extension code) may input an acquisition path 301 of the target native code and the target extension code that need to be extracted in the setting interface 300.

The acquisition path 301 may be a local path (for example, a folder a in a disk of the detection device D), or may also be any path that can capture a code body, such as a network path (for example, a URL link address), which is not limited in this embodiment of the present application. For example, for the linux system, the detection device can capture the target native code and the target extended code specified by the user through the git address.

Further, as shown in fig. 3, the setting interface 300 may further set constraints such as an acquisition range 302 and/or an acquisition period 303, so as to improve the capturing efficiency of the target native code and the target extended code.

Since the code amount of the native operating system and the extended operating system is very large, the user may further screen a certain part or a certain type of file under the acquisition path 301 set by the user by setting the acquisition range 302, for example, a file with an acquisition suffix of ". java" is set in the acquisition range 302. The target native code and the target extended code required by the user can be rapidly acquired in a targeted manner by setting the acquisition range 302, and the timeliness of the acquired target native code and the acquired target extended code can be ensured by setting the acquisition period 303.

Of course, those skilled in the art may set other constraint conditions, for example, set an acquisition date and the like, according to an actual application scenario or actual experience, which is not limited in this embodiment of the present application.

In step 201, the detection device may obtain a target native code and a target extended code specified by a user according to setting information such as a collection path input by the user. For example, when the acquisition path is a local path, the detection device may copy the target native code and the target extended code in the local path to the memory; when the collection path is a network path, the detection device may download the target native code and the target extended code from the network path to the local.

Of course, the detection device may also preset default setting information such as a default acquisition path, and then, through the default setting information, the detection device may automatically acquire the target native code and the target extended code, which is not limited in this embodiment of the present application.

Optionally, after the detection device acquires the target native code and the target extension code, the detection device may further display the acquired target native code and the target extension code to a user in a display interface of the detection device.

Further, as shown in fig. 4, the detection device may further mark, in a display interface of the detection device, a paragraph where a difference occurs between the obtained target native code 401 and the target extension code 402 (for example, by way of bolding and underlining marks in fig. 4), so that the user may quickly and intuitively know the difference between the current target native code 401 and the target extension code 402.

202. The detection equipment divides the target extended code into N continuous code blocks by comparing the target native code with the target extended code, wherein N is more than or equal to 1.

The code block is divided according to the following principle: the code sections of the target extension code that are continuously the same as the target native code may be regarded as one code block, and the code sections of the target extension code that are continuously different from the target native code may be regarded as one code block.

Then, as shown in FIG. 5, the detection device may determine by comparing the target native code 401 and the target extension code 402 shown in FIG. 4: lines 1-8 in the target extension code 402 are the same as lines 1-8 in the target native code 401, then lines 1-8 in the target extension code 402 may be considered as code block 1; line 9 in the target extension code 402 is not the same as line 9 in the target native code 401, then line 9 in the target extension code 402 may be taken as code block 2; lines 10-12 in target extension code 402 are the same as lines 10-12 in target native code 401, then lines 10-12 in target extension code 402 may be taken as code blocks 3, … … until target extension code 402 is divided into 7 consecutive code blocks as shown in FIG. 4.

Of course, as also shown in fig. 5, the process of dividing the target native code 401 into code blocks may also be displayed in a display interface of the detection device, for example, the target native code 401 and the target extension code 402 are displayed by a split-screen method, which is not limited in this embodiment.

203. And the detection equipment evaluates at least one code block in the N code blocks respectively to obtain the evaluation result of the whole target spread code.

The code block types that may occur may be preset in the detection device, for example, 4 code block types are stored in the detection device in advance. Type 1 refers to a case where one code block is identical in the target native code and the target extended code, for example, the code block 1 described above; type 2 refers to a case where a code block is not present in the target native code but is newly added in the target extended code, for example, the above-described code block 2; type 3 refers to a case where a code block appears in the target native code and is deleted in the target extended code; type 4 refers to a case where a code block is modified based on native code, for example, the value of the integer type (int) parameter c2 in the code block 6 of the target extension code 402 in fig. 5 is modified from 2 to 3.

For code block type 4, it may be further divided into different subtypes, for example, when only the variable is modified, its code block type is type 4-1; when only the function name is modified, its code block type is type 4-2; when only the return value is modified, its code block type is type 4-3; when the function name and the return value are modified at the same time, the code block type is type 4-4, and the like, which is not limited in any way by the embodiment of the present application.

In addition, the destructiveness of the code blocks of different code block types to the native code is generally different, that is, after the target native code is upgraded, the probability of the collision phenomenon of different code blocks in the target extended code is different.

For example, for the code block 1 shown in fig. 5, since the type of the code block 1 is type 1, that is, the code block 1 is completely the same as the code 1 'at the same position in the target native code, if the code 1' in the target native code is modified during upgrading, the code block 1 in the target extended code only needs to be modified the same, so that the code block 1 in the target extended code can be compatible with the upgraded target native code. That is, the type 1 code block is less destructive to the native code, and the probability of the subsequent collision phenomenon caused by the code upgrade is also less.

Whereas for the code block 6 shown in fig. 5, since the type of the code block 6 is type 4, i.e. the code block 6 is modified compared to the code 6 'at the same position in the target native code, if the code 6' in the target native code is modified when upgrading the new feature, then the code block 6 in the target extension code cannot support the new feature at this time. That is, the type 4 code block is more destructive to the native code, and the probability of the subsequent collision phenomenon caused by the code upgrade is also higher.

Then, in step 203, the detection device may evaluate each of at least one code block (e.g., each of the code blocks 1-7) of the N code blocks according to the type of the code block, so as to obtain an evaluation result that may reflect the risk of collision occurring subsequently to the target extension code. For example, after the detection device evaluates X (X < N) code blocks of the N code blocks, respectively, the evaluation results of the X code blocks in the target spreading code can be obtained, and the evaluation results of the X code blocks can also be used as the evaluation results of the entire target spreading code, so that the risk of occurrence of a collision phenomenon of the entire target spreading code is reflected to a certain extent. And after the detection device evaluates each of the N code blocks, the obtained evaluation results of the N code blocks can be used as the evaluation results of the whole target spread code, and the evaluation results can comprehensively reflect the risk of the collision phenomenon of the whole target spread code.

For example, each code block may be scored by a scoring system according to the type of the code block, for example, when the code block type of one code block is type 1, the score of the code block is 1; when the code block type of one code block is type 2 or type 3, the score of the code block is 3; when the code block type of one code block is type 4, the score of the code block is 5.

Thus, taking 7 code blocks shown in fig. 5 as an example, the scores of the code block 1, the code block 3, the code block 5, and the code block 7 are all 1 score, the scores of the code block 2 and the code block 4 are all 3 score, and the score of the code block 6 is 5 score. Then, the total score of the entire target spreading code 402 is: 1 × 4+3 × 2+5 is 15 points, and at this time, scoring information such as the score of the code block and the total score of the entire target spread code 402 may be used as the evaluation result of the target spread code 402.

Of course, the detection device may further determine, according to the total score of the entire target spreading code 402, a risk assessment of a subsequent collision phenomenon of the target spreading code 402 for the user, and at this time, the risk assessment may be used as an assessment result of the target spreading code 402.

For example, when the total score is greater than 12, the evaluation result of the target spreading code 402 is: the risk of collision is high; when the total score is greater than 5 and less than 12, the evaluation result of the target spreading code 402 is: the risk of collision phenomenon is general; when the total score is less than 5, the evaluation result of the target extension code 402 is: the risk of collision phenomena is small.

In addition, as shown in fig. 6, the detection device may further display the scoring process and the evaluation result to the user on a display interface thereof, so that the user can intuitively determine the probability of the occurrence of the collision phenomenon of different code blocks in the target spreading code.

Further, in addition to the code block type of the code block, the size of each code block in the target extension code (e.g., the number of lines of code in the code block) and the total number of code blocks may also affect the size of the corruption to the target native code.

Specifically, for a target extension code, the smaller the total number of code blocks, the better the continuity of the target extension code is compared with the target native code, and the smaller the difference with the target native code, the less destructive the target native code. And when the size of each code block is larger, the larger the size of each code block is, the better the continuity of the target extended code is compared with the target native code, and the less destructive the target native code is.

Therefore, in other embodiments of the present application, the detection device may further evaluate the target spreading code according to the type of each of the N code blocks, the size of each code block, and the total number of the code blocks, so as to obtain a risk of a subsequent collision phenomenon of each code block.

Still taking 7 code blocks shown in fig. 5 as an example, the detection device may record the type and size of each code block, and further, as shown in table 1, may still score each code block according to the type and size of each code block in a scoring manner. For example, the detection device may store scores corresponding to different code block types and scores corresponding to different code block sizes, and then the detection device may determine the score of each code block according to the corresponding relationships, and finally, as shown in table 1, the detection device may calculate the total score of the entire target extension code 402 as: 2+7+3+7+2+9+3 is 33 points.

Then, the detection apparatus may take the score of each code block described above and the calculated total score-equal score information of the entire target spread code 402 as the evaluation result of the target spread code 402. Or further determining a risk assessment of a subsequent collision phenomenon of the target spreading code 402 for the user according to the total score of the whole target spreading code 402, and adding the risk assessment into the assessment result of the target spreading code 402.

It should be noted that the target extension code may be a specific function, may be a part or all of the code in a code file, or may be a set of files (for example, all code files in a folder or under a path), and through the above embodiment, an evaluation result of the specified target extension code may be obtained.

In addition, in the above embodiments, a specific method for evaluating a code block in a target extension code is exemplified in a manner of scoring, and it can be understood that a person skilled in the art may also set other evaluation methods according to an actual application scenario or actual experience, for example, a risk of a collision phenomenon occurring in the code block in the target extension code is evaluated through technical means such as big data statistics or artificial intelligence, and the embodiments of the present application do not limit this.

204. And the detection equipment displays the evaluation result to a user.

In step 204, the detection device may visually and intuitively display the evaluation result obtained in step 203 to the user through a visualization means, so that the user can visually evaluate and analyze the destructiveness of the target extension code on the native code, thereby modifying the target extension code in time and reducing the probability of a collision phenomenon in a subsequent upgrade process.

For example, as shown in fig. 7, the detection device may present, in a display interface thereof, an evaluation result interface 701 shown in table 1 to a user, where a score of each code block in the target extension code is displayed in the evaluation result interface 701, and a risk situation of a collision phenomenon that is evaluated by the detection device according to the score of each code block.

Further, as shown in fig. 8, if the user clicks a certain code block or the scoring of the code block, or moves the cursor to the position of the corresponding code block. The detection device may present scoring details when evaluating the code block to the user in a form of popping up a floating window 702, for example, the floating window 702 in fig. 8 shows details of the code block type, the code block size, the risk level, and a modification policy of the code block 6, and if the user confirms to execute the modification policy, the detection device may automatically modify and optimize the code block 6, which is not limited in this embodiment of the present application.

The method for determining the code block modification policy by the detection device will be described in detail in step 205, and thus will not be described herein again.

Or, the detection device may also present the evaluation result to the user in a display interface thereof through the color and the size of the color block. Specifically, the detection device may mark different code block types as different colors, for example, as shown in fig. 9, according to the change of the color depth, the code block type 4 with the highest probability of occurrence of the collision phenomenon is marked as black, the

code block types

2 and 3 with the same probability of occurrence of the collision phenomenon are marked as gray (indicated by diagonal filling in fig. 9), and the code block type 1 with the smaller probability of occurrence of the collision phenomenon is marked as white. And the size of the color block may indicate the size of the corresponding code block. Then, as shown in fig. 9, a color block 801 is used to indicate a code block 1, a color block 802 is used to indicate a code block 2, … …, and a color block 807 is used to indicate a code block 7. Through the specific position, color and size of the color blocks, which part of the target extension code is easy to generate the collision phenomenon, the severity of the collision phenomenon and the like can be vividly displayed to a user, and the user can conveniently optimize the target extension code.

Further, as shown in fig. 10, a specific code of a corresponding code block may also be displayed in each color block, which is convenient for a user to locate problems occurring in each code block in time.

Further, as shown in fig. 11, if the user clicks a color block or moves the cursor to the corresponding color block, the detection device may display scoring details when evaluating the code block in the color block to the user in a form of popping up a floating window 820, for example, the floating window 820 in fig. 11 displays details of the code block type, the code block size, the risk level, the modification policy, and the like of the code block 6, which is not limited in this embodiment of the application.

In addition, in the above embodiment, a specific method for presenting the evaluation result to the user is illustrated in the form of a table and a color block, and it can be understood that a person skilled in the art may also set other visualization presentation methods according to an actual application scenario or actual experience, which is not limited in this application embodiment.

205. And the detection equipment determines a modification strategy of the target extension code according to the evaluation result.

206. The detection equipment executes the modification strategy on the target extension code so as to reduce the destructiveness of the target extension code on the target native code.

In one possible design approach, modification strategies for different code block types may be pre-stored in the detection device. For example, for the type 4 code block, such as the code block 6, in which the int parameter value is directly modified, the modification policy may be preset as follows: the code block of the type 4 is optimized into the code block of the type 3 with smaller collision risk, so that the score of the code block 6 is reduced, and the destructiveness of the whole extension code to the native code is reduced.

That is, as shown in fig. 12, the detection device may convert the code block type of the code block 6 by performing semantic analysis on the target extension code, and convert the code block 6 with a high risk of collision in the target extension code into a code block of type 2 with a low risk of collision.

For example, in the code block 6, the target native code "int c2 ═ 2" is modified to "int c2 ═ 3", and this modification manner of directly modifying the value of the variable increases the probability of subsequent collision phenomenon, so the detection apparatus may modify "int c2 ═ 3" in the code block 6 to:

“int c2＝2；

int c4＝3；

c2＝c4；”

in this way, compared with the target native code, the target extension code is obtained by adding two lines of code on the basis of "int c2 ═ 2" in the target native code, and the purpose of assigning c2 to 2 is also achieved, but at this time, the type of the modified code block 6 is converted into type 3 with less risk of collision, so that the destructiveness of the whole extension code on the native code is reduced.

In another possible design approach, the detection device may also set different modification strategies for the structure of the entire target spreading code.

Specifically, the less the total number of code blocks of the target extension code, the larger the size of the code blocks, the less destructive the target native code, that is, the less the color blocks of the target extension code, the larger the color blocks, the less destructive the target native code. Therefore, the detection device may preset a modification strategy for merging some color blocks, so as to reduce the total number of the color blocks of the target extension code, increase the size of each code block, thereby reducing the score of the whole target extension code (in this application, the lower the score of the target extension code is, the smaller the collision risk is, for example), and reduce the destructiveness of the extension code on the native code.

For example, as shown in fig. 13, the detection device performs semantic analysis on the target extension code to confirm that the setting position of the code block 4 does not affect the operation of the entire target extension code, and then the detection device may merge the code block 4 with the code 2, reduce the total number of code blocks in the merged target extension code from 7 blocks to 5 blocks, and increase the size of the code block accordingly, thereby reducing the score of the entire target extension code.

Of course, as shown in fig. 14, the detection device may also execute the two modification strategies, i.e., the conversion code block type shown in fig. 12 and the code block merging shown in fig. 13, on the target extension code at the same time, so as to further reduce the score of the whole target extension code, thereby reducing the destructiveness of the extension code on the native code, and reducing the probability of subsequent collision.

In addition, in step 206, after the detection device determines the modification policy for the target extension code, the modification policy may be automatically executed, or the detection device may be manually triggered by the user to execute the modification policy. For example, after obtaining the modification policy of combining the code block 4 and the code 2 in the target extension code, the detection device may prompt the user through the human-computer interaction interface as shown in fig. 15 whether to execute the modification policy, and if it is detected that the user clicks a confirmation button in the human-computer interaction interface, the detection device combines the code block 4 and the code 2 in the target extension code in response to the trigger operation.

Of course, when the user is prompted whether to execute the modification policy, the modification policy may be manually adjusted or parameters when the modification policy is executed may also be set in the human-computer interaction interface, for example, the time for executing the modification policy is modified, the number of code blocks that need to be merged, and the like, so that the user can control the execution process of the modification policy, and the modification efficiency of the target extension code is improved.

It should be noted that, in the embodiment of the present application, the execution order between

steps

204 and 205 is not limited at all.

In addition, in the embodiment of the present application, the detection device may further set a storage condition for inputting the target extension code into the code library according to the evaluation result. For example, as shown in (a) of fig. 16, the warehousing condition may be: and when the total score of the target extension code is greater than a preset reference value, allowing the target extension code to be launched from the development environment into a code library in the production environment. For another example, as shown in fig. 16 (b), the storage condition may be: when the target extension code does not contain the code block of the code block type 4, the target extension code is allowed to be launched from the development environment into a code library in the production environment.

When the target extension code does not meet the warehousing condition, the target extension code cannot be warehoused, then developers need to further optimize the target extension code until the warehousing condition is met, and the optimized target extension code cannot be put into a code base in a production environment from a development environment to run.

Therefore, the code quality of the extended codes running in the code base can be strictly controlled, the extended codes with larger destructiveness to the native codes are effectively prevented from being used, and the conflict phenomenon between the native codes and the extended codes caused by the upgrade of the native codes is reduced.
