Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment provides a data mirror image control method, which is based on the method of the embodiment, does not need to abstract virtual equipment when data mirror image is carried out, does not need to restart the equipment and does not need to interrupt service, and provides convenience for users. Specifically, in this embodiment, mirror image data is first obtained, an objective callback function is determined based on the mirror image data, and the objective callback function and the mirror image data are stored in a message queue. And then, when the mirror event is executed, acquiring the target callback function from the message queue, and calling the mirror data to carry out mirror processing based on the target callback function. And finally, after the mirror image processing is finished, acquiring an initial callback function, replacing the target callback function by the initial callback function, and performing data synchronization by using the initial callback function. The invention can call the mirror image data based on the target callback function, and re-synchronize the data based on the initial callback function after the mirror image event is executed.
The data mirror image control method of the embodiment can be applied to a terminal, and the terminal can be an intelligent product terminal such as a computer and a mobile phone. In this embodiment, as shown in fig. 1, the data mirroring control method includes:
and step S100, obtaining mirror image data, determining a target callback function based on the mirror image data, and storing the target callback function and the mirror image data into a message queue.
In this embodiment, mirror image data is first obtained, where the mirror image data is data that needs to be mirrored on a terminal. Because the embodiment does not need to abstract virtual equipment to realize the calling and mirror processing of mirror data and mirror processing of the mirror data, the embodiment can determine the target callback function according to the mirror data so as to call the mirror data and mirror processing based on the target callback function. After mirror image data and a target callback function are acquired, the mirror image data and the target callback function are stored into a message queue, and execution of a mirror image event is waited.
In one implementation, the present embodiment is used in determining the target callback function. The method comprises the following steps:
step S101, based on the mirror image data, determining type information of the mirror image data, wherein the type information is used for reflecting the data type of the mirror image data;
step S102, determining a target virtual device for carrying out mirror image processing on the mirror image data based on the type information, and acquiring a target callback function corresponding to the target virtual device.
After mirror image data is acquired, the mirror image data is analyzed, and type information of the mirror image data is determined, wherein the type information is used for reflecting the data type of the mirror image data. In order to facilitate the call to the mirror image data, the embodiment can set different callback functions for the mirror image data of different data types so as to determine a corresponding target callback function based on the type information of the mirror image data, wherein the target callback function is used for calling the mirror image data corresponding to the type information and is only used for calling the mirror image data corresponding to the type information.
Specifically, after the type information of the mirror image data is analyzed, the target virtual device for performing mirror image processing on the mirror image data is determined, wherein the target virtual device is preset, is used for performing data mirror image, and is only used for performing data mirror image on the data type corresponding to the analyzed type information. In a specific application, the embodiment presets a preset equipment library, wherein the preset equipment library comprises a plurality of virtual equipment and function information of each virtual equipment, and the function information corresponds to a data type of data subjected to mirror image processing by using the virtual equipment. That is, the present embodiment sets a corresponding callback function for each type of information in advance, and therefore, the function information of the set callback function corresponds to the data type of the data subjected to the mirroring processing using the virtual device. And after the type information is matched with the preset equipment library, obtaining the target virtual equipment corresponding to the type information at the moment. After the target virtual device is determined, the embodiment can directly call the target callback function of the target virtual device.
In a specific application, the type information of the embodiment may include system class data and software application class data, where the system class data is data related to an operating system of the terminal, such as system installation data and system update data. The software application class data is data of an application program installed in the terminal, such as application program installation data, application program version update data, and the like. According to the embodiment, different virtual devices can be set according to the system class data and the software application class data, and different target callback functions are set for different virtual devices, so that after the type information of the mirror image data is determined, the corresponding target virtual device and the target callback function corresponding to the target virtual device can be determined quickly, and the data processing efficiency is improved. In addition, the software application class data can be subdivided according to the attribute of the software application, and the software application class data is further divided into the system self-contained software class data and the uninstallable software class data, so that different target callback functions can be conveniently and further used for different software application class data, the mirror image data can be classified more finely, and the retrieval accuracy of the target callback functions is improved.
And step 200, when a mirror event is executed, acquiring the target callback function from the message queue, and calling the mirror data to carry out mirror processing based on the target callback function.
When the terminal starts to execute the mirror event, the embodiment obtains the target callback function from the message queue, then calls mirror data based on the target callback function, and performs mirror processing on the mirror data. When a plurality of mirror image data are stored in the message queue according to the priority order, when a mirror image event is executed, the terminal firstly acquires mirror image data with high priority and a corresponding target callback function according to the priority order to carry out mirror image processing, and then acquires mirror image data with low priority and a corresponding target callback function to carry out mirror image processing.
In one implementation manner, the method in this embodiment includes the following steps when performing the mirroring process:
step 201, calling the mirror image data based on the target callback function, and judging whether original data corresponding to the mirror image data exists or not;
step S202, if original data exist, incremental data of the mirror image data relative to the original data are obtained;
and step S203, calling the incremental data based on the target callback function to carry out mirror image processing.
In this embodiment, since the virtual device is not required to be abstracted to perform data mirroring in this embodiment, but the target callback function determined in this embodiment corresponds to the corresponding virtual device, and the function of the target callback function is a function for implementing the virtual device, the mirroring process can be performed based on the target callback function. Specifically, the terminal firstly calls the mirror image data based on the target callback function, and judges whether original data corresponding to the mirror image data exists or not, wherein the original data is initial data corresponding to the mirror image data. For example, when the mirror image data is system class data, the mirror image data obtained currently is the latest version of system data, and the original data is the old version of system data. For another example, when the image data is software application data, the currently acquired image data is the latest version of software installation data, and the original data is the old version of software installation data.
In one implementation manner, if the terminal has original data, in order to save the time of data mirroring in the subsequent step and improve the efficiency of data mirroring, the embodiment may only obtain incremental data of the mirrored data relative to the original data, where the incremental data reflects data added by the current mirrored data relative to the original data, such as an increase of a function of an operating system, etc., and then the terminal may directly call back the incremental data according to a target dropping function and execute a mirroring event, so as to mirror the incremental data into the terminal. Of course, in another implementation manner, after determining that the original data exists in the terminal, the embodiment may also only obtain the decrement data of the mirror image data relative to the original data, where the decrement data reflects the data reduced by the current mirror image data relative to the original data, such as the function deletion of the software application, where the terminal may generate an operation instruction based on the decrement data, and modify the original data in the terminal according to the operation instruction, so that the modified original data is the same as the mirror image data, which eliminates the complicated step that most of the data needs to be covered in the traditional data mirror image, and only needs to delete the redundant data, thereby achieving the purpose of data mirror image.
Specifically, in this embodiment, if possible, the mirror image data is parsed to obtain parsed content. And then acquiring the original content corresponding to the original data. Then, the embodiment performs segmentation processing on the parsed content and the original content according to the same component to obtain a plurality of first content segments corresponding to the parsed content and a plurality of second content segments corresponding to the original content. That is, in this embodiment, when the parsing content and the original content are segmented based on the same segmentation method, a plurality of groups of content groups including a first content segment and a second content segment can be obtained, and when the first content segment and the second content segment are respectively compared, the first content segment and the second content segment in the same content group are respectively compared, and specifically, a first check value of the first content segment and a second check value of the second content segment in the same content group can be respectively determined. And comparing the first check value with the second check value, if the first check value is different from the second check value, indicating that the difference exists between the first content segment and the second content segment at the moment, based on the difference, rapidly analyzing the data with the difference in the first content segment and the second content segment of each content group, further rapidly obtaining the increment data or the decrement data, and determining the increment data.
In other implementations, if the terminal does not have the original data, it is indicated that the terminal has not installed the mirror image data before, and at this time, the embodiment may directly perform the mirror image processing on the mirror image data obtained at this time through the target callback function, so that the terminal stores the mirror image data.
And step S300, after the mirror image processing is finished, acquiring an initial callback function, replacing the target callback function by the initial callback function, and performing data synchronization by using the initial callback function.
In this embodiment, after the mirror event is executed, in order to intercept data in time and ensure that the terminal can operate normally, the embodiment may obtain an initial callback function, and replace the target callback function with the initial callback function. Then, the embodiment uses the initial callback function to execute the operation requirement of the terminal, and uses the initial callback function to perform data synchronization, wherein the data synchronization is to synchronize the mirror image data to the system of the terminal, so as to ensure that the terminal can normally operate after the data mirror image is completed. Therefore, after the data mirror image is finished, the terminal can complete data synchronization without restarting the terminal, so that the effectiveness of the data mirror image is ensured, and the normal use of a user is ensured.
In one implementation, the method in this embodiment includes the following steps when performing data synchronization:
step 301, obtaining mirror image position information corresponding to the incremental data, where the mirror image position information is used to reflect the position where the incremental data is stored after mirror image processing is performed on the incremental data;
step S302, acquiring the incremental data based on the mirror image position information through the initial callback function, and synchronizing the incremental data;
step S303, monitoring the synchronous state in real time, if the synchronous state is interrupted, acquiring the unsynchronized data, recording the unsynchronized data, and continuing to synchronize the unsynchronized data when the terminal is restarted next time.
Specifically, in this embodiment, first, mirrored position information corresponding to incremental data is obtained, where the mirrored position information is used to reflect a position where the incremental data is stored after the incremental data is mirrored. When the method is specifically applied, the image position information can be a bitmap, so that the terminal can conveniently and quickly position the incremental data, then the embodiment obtains the incremental data based on the image position information through the initial callback function and synchronizes the incremental data to a system of the terminal, and the embodiment switches the initial callback function to perform data synchronization at the moment, can be used for verifying whether the mirrored incremental data is valid or not, and is beneficial to ensuring that the mirrored incremental data can be normally invoked in the terminal system. Thus, the situation that the terminal is restarted to cause the service to be interrupted can be avoided. In addition, the terminal in this embodiment monitors the synchronization status in real time, if the synchronization status is interrupted, the synchronization fails at this time, the terminal may acquire the unsynchronized data, record the unsynchronized data, and then control the terminal to continue synchronizing the unsynchronized data when restarting next time. If the synchronization state is not interrupted, the data synchronization is successful, the terminal enters an operation page to complete data mirroring and synchronization, and normal use of the terminal is ensured.
In summary, the embodiment first obtains mirror image data, determines a target callback function based on the mirror image data, and stores the target callback function and the mirror image data into a message queue. And then, when the mirror event is executed, acquiring the target callback function from the message queue, and calling the mirror data to carry out mirror processing based on the target callback function. And finally, after the mirror image processing is finished, acquiring an initial callback function, replacing the target callback function by the initial callback function, and performing data synchronization by using the initial callback function. The invention can call the mirror image data based on the target callback function, and re-synchronize the data based on the initial callback function after the mirror image event is executed.
