Obviously, the drawings in the following description are some embodiments of the present disclosure. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0033] It can be understood that before using the technical solutions disclosed in the embodiments of the present disclosure, the types, usage scopes, usage scenarios, etc. of the personal information involved in the present disclosure shall be informed to the user and the user's authorization shall be obtained in an appropriate manner in accordance with relevant laws and regulations.

[0034] For example, when receiving the user's active request, a prompt message is sent to the user to clearly prompt the user that the operation requested by the user will require obtaining and using the user's personal information. Thus, the user can autonomously choose whether to provide personal information to software or hardware such as an electronic device, application program, server, or storage medium that performs the operations of the technical solutions of the present disclosure according to the prompt message.

[0035] As an optional but non-limiting implementation manner, the manner of sending a prompt message to the user in response to receiving the user's active request may be, for example, in the form of a pop-up window, and the prompt message may be presented in text in the pop-up window. In addition, the pop-up window may also carry a selection control for the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0036] It can be understood that the above process of notifying and obtaining the user's authorization is only illustrative and does not limit the implementation manner of the present disclosure. Other manners that meet relevant laws and regulations can also be applied to the implementation manner of the present disclosure.

[0037] In the actual application development process, the implementation of a service in the operating system often requires multiple modules and multi-level calls to achieve. When any problem occurs at any level, it often causes the application to exit, or the entire call chain associated with that level to be abnormal.

[0038] Figure 1It is a hierarchical schematic diagram of business association within an operating system. As Figure 1 shown, this business is used to print an array, which includes five numbers from 1 to 5. Among them, the printitem11 function provides the atomic ability to print a single number, printall12 provides the ability to print all numbers by traversing the printitem11 atomic ability, and starttest13 is the business entry point, which calls printall12 to execute the printing requirement.

[0039] In this business, when an exception occurs in any printitem, according to the current fault handling mechanism, it will directly jump from the faulty printitem to the outermost layer for exception handling. That is, printitem → printall → starttest → exception handling. When using the above method for exception handling, other printitems behind the faulty printitem will not have the opportunity to be executed. And if there is other logic after the call to printall and starttest, it will also not have the opportunity to be executed. Therefore, the current fault handling method may cause subsequent business losses.

[0040] In the process of solving the above technical problems, the inventor found through research that in order to avoid business losses during fault repair, the fault repair can be limited within the faulty printitem, and the subsequent levels can be kept running, so as to minimize the loss in user experience and business.

[0041] Optionally, when a fault occurs in any target function, a repair file sent by the cloud server can be obtained. Among them, the repair file includes location information for locating the target function and repair information for repairing the target function.

[0042] Therefore, the location and modification of the target function can be dynamically performed based on the Apect atomic ability built into the operating system and the atomic ability obtained by dynamically loading classes. And the target function is replaced based on the modified update function. Thus, the repair operation of the target function can be dynamically realized during the application runtime without affecting other subsequent functions, so as to minimize the loss in user experience and business.

[0043] In order to solve the technical problem that application faults in the operating system cannot be quickly repaired, the present disclosure provides a fault repair method, apparatus, device, computer-readable storage medium, and product.

[0044] It should be noted that the fault repair method, apparatus, device, computer-readable storage medium, and product provided by the present disclosure can be applied to any fault repair scenario within an operating system.

[0045] Figure 2 is the system architecture diagram on which the present disclosure is based. As Figure 2 shown, the system architecture on which the present disclosure is based at least includes a cloud server 21 and a terminal device 22. Among them, the terminal device 22 uses a preset operating system.

[0046] Based on the above system architecture, when a target function in any application in the terminal device 22 fails, an error message can be sent to the cloud server 21. Therefore, the cloud server 21 can send a repair file to the terminal device 22. Therefore, the terminal device 22 can dynamically locate and modify the target function based on the Apect atomic capabilities built into the operating system and the dynamically loaded classes to obtain atomic capabilities. And perform a replacement operation on the target function based on the updated function after modification.

[0047] Figure 3 is a schematic flowchart of a fault repair method provided by an embodiment of the present disclosure, which is applied to an operating system. As Figure 3 shown, the method includes:

[0048] Step 301, obtain a repair file for a target function sent by a cloud server, where the repair file includes location information and repair information associated with the target function. The location information is used to locate the target function in the source code file associated with the target application, and the repair information includes exception protection information and / or parameter repair information. The repair file is generated by the cloud server after obtaining the error message uploaded by the operating system.

[0049] The execution subject of this embodiment is a fault repair device, and the fault repair device can be coupled to a preset operating system. The operating system is installed in a terminal device communicatively connected to the cloud server. Among them, the operating system can be any operating system set in the terminal device. For example, the operating system can be the HarmonyOS.

[0050] In this embodiment, when any target function in the operating system fails, an error message can be sent to the cloud server. Therefore, the cloud server can generate a repair file based on the error message. Wherein, the repair file includes location information and repair information associated with the target function. The location information is used to locate the target function in the source code file associated with the target application, and the repair information includes exception protection information and / or parameter repair information.

[0051] Optionally, the location information may include the module class where the class to which the target function belongs is located, and the specific value may be the final absolute path of the target class; the location information may also include data such as the class to which the target function belongs, the export method of the target class in the module, the target function name, and whether it is of the static type.

[0052] This exception protection information is used to return a preset result value when an exception occurs in the target function. The exception protection information may include a message condition (messageCondition), a fault message, and a comparison method (messageOperation) between the fault message and a preset error message condition. The comparison method includes any one of inclusion, equality, greater than, and less than. It also includes a call stack condition (stackCondition) and a comparison method (stackOperation) between the actual call stack and the call stack condition. The comparison method includes any one of inclusion, equality, greater than, and less than. The exception protection information may further include a preset result value and the type of the result value. For example, the type may be a number, a string, or a complex object.

[0053] This parameter repair information is used to adjust the parameters of the target function when a fault occurs in the target function. The parameter repair information may include the total number of parameters (paramSize) of the function, the index (paramModifiyIndex) of the parameter to be modified, starting from 0, a parameter condition value (paramCondition), an operator (operation) for judging the parameter value. The judgment method includes any one of inclusion, equality, greater than, and less than, a new parameter value (paramNew), and a new parameter value type (paramNewType). For example, the type may be a number, a string, or a complex object.

[0054] Step 302: Dynamically locate the target function in the source code file based on the positioning information when the target application is running.

[0055] In this embodiment, after obtaining the repair file, based on the built-in capabilities of the operating system, the target function can be dynamically located in the source code file based on the positioning information when the target application is running.

[0056] Step 303: Perform a modification operation on the target function based on the repair information to obtain an updated function.

[0057] In this embodiment, since the repair file includes exception protection information and / or parameter repair information, the target function can be modified based on the repair information to obtain an updated function.

[0058] Optionally, the repair information capable of fixing the fault type can be determined based on the current fault type, and the target function can be modified based on the repair information to obtain an updated function.

[0059] Alternatively, the modification operation of the target function can also be achieved based on the exception protection information and the parameter repair information together to obtain an updated function.

[0060] Step 304: Replace the target function in the source code file through the update function.

[0061] In this embodiment, after the target function is transformed based on the repair information, the target function can be replaced with the update function. Therefore, when the application runs subsequently, the update function can be called for data processing.

[0062] Since the update function includes exception protection information and / or parameter repair information, when a failure occurs, the failure can be processed within the function based on the exception protection information and / or parameter repair information, avoiding affecting other functions.

[0063] Taking an actual application as an example, the operating system can be the HarmonyOS. When a failure occurs in any target function in the HarmonyOS, the error message can be uploaded to the cloud server. Therefore, the cloud server can generate a repair file based on the error message. The repair file includes location information for locating the target function and repair information for repairing the target function. Therefore, after the HarmonyOS obtains the repair file, it can dynamically locate the target function based on the location information and modify the target function based on the repair information to obtain an update function. Subsequently, the target function can be replaced by the update function without affecting other subsequent functions.

[0064] The fault repair method provided in this embodiment can obtain the repair file sent by the cloud server when any target function fails. The repair file includes location information for locating the target function and repair information for repairing the target function. Therefore, the target function can be dynamically located and modified based on the Apect atomic capability built into the operating system and the dynamic loading class to obtain the atomic capability. And the target function is replaced based on the modified update function. Thus, the repair operation of the target function can be dynamically realized during the application running without affecting other subsequent functions, thereby minimizing the loss of user experience and business.

[0065] Figure 4 It is a schematic flowchart of the fault repair method provided in another embodiment of the present disclosure. Based on any of the above embodiments, as Figure 4 shown,

[0066] Step 401: Determine multiple classes to be compiled in the source code file.

[0067] Step 402: Determine the relative path corresponding to the class to be compiled, and determine the absolute path corresponding to the class to be compiled based on the relative path.

[0068] Step 403: Adjust the reference relationship of the class to be compiled to the absolute path through a preset compilation tool.

[0069] In this embodiment, the original operating system does not support dynamically implementing the search for the target class in the way of a complete variable expression. Configuration needs to be carried out in the source code in advance, so it is impossible to implement the dynamic distribution of different parameters.

[0070] In order to be able to implement the dynamic distribution of parameters, non-source-code-level parameters can be adopted to avoid compilation period restrictions and runtime search failures, and the configuration parameters are confirmed by collecting the complete path code (absolute path) after the final obfuscation of the compilation product.

[0071] Optionally, multiple classes to be compiled in the source code file can be determined. For each class to be compiled, its corresponding relative path is determined, and the absolute path corresponding to the class to be compiled is determined based on the relative path. During the compilation process, the reference relationship of the class to be compiled is adjusted to the absolute path through a preset compilation tool.

[0072] The fault repair method provided in this embodiment can avoid the problems of compiler restrictions and runtime search failures by adjusting the reference relationship of the class to be compiled to the absolute path, and can accurately locate the target function based on the location information during the application running process.

[0073] Further, on the basis of any of the above embodiments, step 302 includes: the location information includes the absolute path of the module to which the target function belongs, the absolute path of the class to which the target function belongs, the export method, and the function name.

[0074] The location information is searched through the preset dynamic class loading ability in the operating system to obtain the class object associated with the target function, and the target function is determined in the class object.

[0075] In this embodiment, the location information includes the absolute path of the module to which the target function belongs, the absolute path of the class to which the target function belongs, the export method, and the function name.

[0076] Optionally, the operating system provides an atomic ability to dynamically load classes, which supports dynamically locating functions during the application running. Therefore, the location information can be searched through the preset dynamic class loading ability in the operating system to obtain the class object associated with the target function, and the target function is determined in the class object.

[0077] Since using the absolute path can improve the maintainability of the code and avoid complex relative paths. Therefore, by using the absolute path for the location of the target function, the location operation of the target code can be more accurately implemented.

[0078] The fault repair method provided in this embodiment locates the positioning information by dynamically loading the class capabilities, obtains the class object associated with the target function, and thus can accurately locate the target function based on the capabilities built into the operating system. In addition, by using the absolute path for the positioning of the target function, the accuracy of the target function positioning can be improved.

[0079] Further, based on any of the above embodiments, step 304 includes:

[0080] Perform a re-assignment operation on the function attributes of the class object based on the update function.

[0081] In this embodiment, after the target function is located based on the positioning information, a re-assignment operation can be performed on the function attributes of the class object based on the update function. Thus, during the subsequent application operation, the update function can be directly called for data processing.

[0082] The fault repair method provided in this embodiment can accurately implement the replacement operation of the target function during the operation by performing a re-assignment operation on the function attributes of the class object based on the update function.

[0083] Further, based on any of the above embodiments, the exception protection information includes a preset first condition and a preset result value, and the parameter repair information includes a preset second condition and a preset parameter.

[0084] Further, based on any of the above embodiments, step 303 includes:

[0085] Add the exception protection information and / or parameter repair information at the position associated with the target function through the preset Aspect atomic capability in the operating system to obtain the update function.

[0086] Wherein, after the target function is modified based on the exception protection information, the update function is used to return the preset result value when it is determined that the fault information of the target function meets the preset first condition during the call process.

[0087] After the target function is modified based on the parameter repair information, the update function is used to update the parameter associated with the target function to the preset parameter when it is determined that the fault information of the target function meets the preset second condition during the call process.

[0088] In this embodiment, the operating system provides certain Aspect atomic capabilities. Based on these capabilities, some modification capabilities can be added during the application operation. It supports adding custom logic before and after other class methods or replacing the original method.

[0089] After the target function is located based on the positioning information, abnormal protection information and / or parameter repair information can be added at the position associated with the target function through the preset Aspect atomic capability in the operating system to obtain an updated function.

[0090] Figure 5 The schematic diagram of the updated function provided by the embodiments of the present disclosure is as Figure 5 shown. After the target function is transformed, an updated function can be obtained. The updated function 51 includes the target function 52, abnormal protection information 53, and parameter repair information 54.

[0091] Optionally, the abnormal protection information includes a preset first condition and a preset result value. Therefore, after the fault information is obtained, the fault information can be compared with the first condition. If the comparison is successful, the preset result value in the abnormal protection information can be fed back. Otherwise, an exception message can be thrown.

[0092] Optionally, the parameter repair information includes a preset second condition and a preset parameter. Therefore, when a fault occurs, if the fault information matches the second condition, the parameter associated with the target function can be updated to the preset parameter.

[0093] Taking an actual application as an example, if the target function is print item, after adding parameter repair information to the target function, an updated function print itemNew can be obtained. Through this parameter repair information, the parameters can be automatically modified, so the call of the target function + new parameters can be executed to achieve the effect of repairing the parameters.

[0094] The fault repair method provided by this embodiment adds at the position associated with the target function through the preset Aspect atomic capability in the operating system to obtain an updated function, so that the modification operation of the target function can be accurately realized. Therefore, during the operation of the updated function, when an error occurs, a preset result value can be returned, or the parameters can be automatically modified. The fault can be repaired within the target function without affecting other functions and levels associated with the target function.

[0095] Further, based on any of the above embodiments, after step 304, it further includes:

[0096] During the operation of the preset application, the updated function is called to process data.

[0097] In this embodiment, after the original target function is replaced based on the updated function, during the operation of the preset application, the updated function can be directly called to process data.

[0098] Optionally, the user can pre-configure the fault types of exception protection information and parameter repair information according to actual requirements. When a fault occurs, the fault type can be determined, and the exception protection information or parameter repair information can be selected based on the fault type for data processing.

[0099] For example, exception protection information can be used for data processing. After obtaining the fault information, the fault information can be compared with the first condition. If the comparison is successful, the preset result value in the exception protection information can be fed back. Otherwise, an exception message can be thrown.

[0100] The fault repair method provided in this embodiment calls an update function for data processing during the operation of a preset application, so that when an error occurs, a preset result value can be returned, or the parameters can be automatically modified to avoid the problem of the application crashing and the system malfunctioning due to a fault in the target function.

[0101] Further, based on any of the above embodiments, the method further includes:

[0102] In response to a fault occurring in the current target code, determine the location information of the target code in the source code file and the fault type.

[0103] Send an error message to the cloud server, where the error message includes the location information and the fault type.

[0104] In this embodiment, in order to quickly implement the repair operation of the target function, when it is determined that a fault occurs in any target code in the operating system, the location information of the target code in the source code file and the fault type can be determined. Based on the location information and the fault type, an error message is determined. The error message is uploaded to the cloud server.

[0105] Optionally, after obtaining the error message, the cloud server can determine the target function that currently has a fault based on the error message, and determine the repair information that matches the fault type in the preset repair data set. Based on the location information and the repair information, a repair file is constructed, and the repair file is fed back to the terminal device so that the terminal device can implement the repair operation of the target function during the application operation based on the repair file.

[0106] Alternatively, after obtaining the error message, the technical personnel can perform fault analysis based on the error message. Determine the repair information that matches the fault type based on the analysis result. Based on the location information and the repair information, a repair file is constructed, and the repair file is fed back to the terminal device.

[0107] The fault repair method provided in this embodiment actively uploads error messages to the cloud server when a fault occurs, so that the cloud server can accurately generate a repair file based on the error messages. Subsequently, the repair operation of the target function can be implemented during the application running process based on the repair file.
