Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a schematic diagram of an implementation environment related to a system data processing method provided by an embodiment of the present invention, and as shown in fig. 1, the implementation environment may include: a development device 110 and at least one terminal 120.
The development device 110 may be a computer. The terminal 120 may be a smartphone, a television set-top box, a tablet computer, a multimedia player, an e-reader, a wearable device, etc. The connection between the development device 110 and the terminal 120 may be established through a communication line, which may be a Universal Serial Bus (USB) line. The development device 110 can operate on the system data in the terminal 120. The system data may include blocks of data that do not need to be changed when the operating system of the terminal 120 is upgraded.
Fig. 2 is a flowchart of steps of another system data processing method provided in an embodiment of the present invention, which is applied to a development device, and as shown in fig. 2, the method may include:
In the embodiment of the present invention, the development device may modify a Universal Boot Loader (Uboot) to establish the fixed partition. For example, the uboot source code may be modified accordingly, and the partitions of the operating system and the storage capacity of each partition may be reallocated to implement establishment of the fixed partition.
In the embodiment of the present invention, the fixed data block is a data block that does not need to be changed when the terminal upgrades the operating system. The fixed data block may be determined according to specific development requirements. Generally, different development requirements may be different for data blocks that need not be changed when upgrading a system. In a specific implementation, one or more fixed data blocks may be used, which is not limited in this embodiment of the present invention. For example, a data block named dumpsys and a data block named am may be determined according to development requirements as data blocks that need not be changed when upgrading.
And 203, generating a fixed data file according to the fixed data block.
Due to the characteristics of the development environment, the data stored in the partition by the development device must be data compressed in a preset format. Therefore, in the embodiment of the invention, the fixed data block can be compressed in a preset format to obtain the fixed data file. For example, the preset format may be a Fourth generation extended file system (ext 4) format. For example, the development device may compress the fixed data blocks in ext4 format to generate a fixed data file, and the resulting fixed data file may be an image file, which may be denoted as img. It should be noted that the preset format may also be another format, which is not limited in the embodiment of the present invention.
And step 204, storing the fixed data file into the fixed partition.
In the embodiment of the invention, the development device can store the fixed data file into the fixed partition in a burning mode. Specifically, the development device can perform burning by using burning software installed on the development device, first, information of the newly-built fixed partition is written into a burning file configuration of the burning software, then, the fixed partition is connected with a terminal through a USB (universal serial bus) line, and finally, the fixed data file is burned into the fixed partition. It should be noted that, in another alternative embodiment of the present invention, the fixed data file may also be stored in the fixed partition in other ways, for example, a copy operation, and the like, which is not limited in the implementation of the present invention.
In summary, in the system data processing method provided in the embodiment of the present invention, the development device may establish the fixed partition under the operating system of the terminal, generate the fixed data file according to the fixed data block in the system partition under the operating system, and finally store the fixed data file in the fixed partition. Therefore, when the terminal upgrades the operating system of the terminal by using the system upgrade package, the fixed data file can be extracted from the fixed data partition, and the fixed data block can be obtained after the fixed data file is decompressed. Therefore, in the embodiment of the present invention, when the system upgrade package only includes data for updating the data block to be updated, the terminal may use the fixed data block in the fixed partition to upgrade the system, thereby reducing the data amount in the system upgrade package, reducing the time for a user to download the system upgrade package, and accelerating the efficiency of system upgrade.
Fig. 3 is a flowchart of steps of a system data processing method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 3, the method may include:
In this embodiment of the present invention, the fixed partition may be established by the development device under the operating system of the terminal, and the fixed data file is stored in the fixed partition by the development device. The fixed data file is obtained after a development device compresses a fixed data block, the fixed data block is a data block which does not need to be changed when the terminal upgrades an operating system, and the fixed data block can be determined according to actual development requirements.
In practical application, when the terminal upgrades the operating system, part of the data blocks in the system partition are generally updated, and although the fixed data files stored in the fixed data partition are fixed data files which do not need to be updated, the data in the fixed data blocks are called in the process of upgrading. The fixed data file preset in the fixed data partition by the development device is a file obtained by compressing the fixed data block through a preset format, so that the data in the fixed data file cannot be directly called in the upgrading process. In this step, the fixed data file needs to be decompressed to obtain a fixed data block, so as to realize system upgrade.
Specifically, the extracted fixed data file may be decompressed through a decompression command to obtain the executable fixed data block. Therefore, in the process of upgrading the system, the data in the fixed data block can be called to ensure that the system is upgraded normally.
And 303, upgrading the system by using the data in the system upgrading packet and the fixed data block.
In the embodiment of the invention, the data block needing to be updated can be updated by using the data in the system upgrading packet, and the data in the fixed data block can be called in the updating process, so that the system upgrading is realized. The data in the fixed data block may also be used during subsequent system operations.
In summary, the system data processing method provided in the embodiments of the present invention may extract the fixed data file in the fixed data partition when the system upgrade package is used to upgrade the operating system of the terminal, and may obtain the fixed data block after decompressing the fixed data file. Therefore, in the embodiment of the present invention, when the system upgrade package only includes data for updating the data block to be updated, the terminal may use the fixed data block in the fixed partition to upgrade the system, thereby reducing the data amount in the system upgrade package, reducing the time for a user to download the system upgrade package, and accelerating the efficiency of system upgrade.
Fig. 4 is a flowchart of steps of another system data processing method provided in an embodiment of the present invention, and as shown in fig. 4, the method may include:
Specifically, the step 201 may be referred to for a specific implementation manner of this step, and details of the embodiment of the present invention are not described herein.
Specifically, the step 202 may be referred to for a specific implementation manner of this step, and details are not described herein in this embodiment of the present invention.
And 403, generating a fixed data file by the development device according to the fixed data block.
Specifically, step 403 may include:
step 4031, the development device compresses the fixed data block according to a preset format to obtain a fixed data file.
Specifically, the specific implementation manner of this step may refer to step 203 described above, and details of the embodiment of the present invention are not described herein.
Specifically, the specific implementation manner of this step may refer to step 204 described above, and details of the embodiment of the present invention are not described herein.
And 405, the developing device stores the name of the fixed data block into a preset android compiled file so that the fixed data block can be determined according to the name when the operating system is modified.
The preset installation compiling file is a file with a compiling function in an android system, and the preset android compiling file can be an android. In practical application, in the development process of the same operating system, there may be a situation where multiple developers develop the same operating system, and therefore it is necessary to ensure that each developer can know which data blocks in a system partition are determined as fixed data blocks, so as to ensure normal development of the system.
Therefore, in the embodiment of the present invention, the names of the fixed data blocks are stored in the preset android compiled file, so that when the operating system is modified again, a developer can quickly determine which data blocks are determined as the fixed data blocks according to the names in the preset android compiled file.
Specifically, during storage, a list may be generated according to the name of the fixed data block, and then the list may be stored in a preset android compiled file. Assuming that there are two fixed data blocks, one of which is named a and the other of which is named b, a list X may be generated, which includes the names a and b.
It should be noted that, in practical applications, when the operating system is modified again, a developer may also determine which data blocks are determined as fixed data blocks by analyzing the fixed data files in the fixed data partition, so that step 405 may be omitted, and development cost is saved.
And 406, adding a decompression command in a preset android script file by the development device so that the terminal converts the fixed data file into an executable fixed data block.
In the embodiment of the present invention, the preset android script file may be an "init. Since the fixed data file is a file compressed in a preset format, the terminal cannot directly use the data in the fixed data file. Therefore, in this step, the development device adds the decompression command to the preset android script file, so that the terminal can decompress the fixed data file according to the decompression command to obtain the fixed data block.
And 407, setting an authority modification interface in a preset android system setting file by the development device so that the terminal can change the file authority of the fixed data block through the authority modification interface.
Because the fixed data block is originally stored in the system partition, after the fixed data block is stored in the fixed partition, the operating system can default to set a lowest file authority for the fixed data block, for example, the file authority is set to be unreadable or unwritable, so that the terminal cannot read and write data in the fixed data block in the operation process, and the operating system cannot normally operate. Therefore, in the embodiment of the invention, the development device can set the permission modification interface in the preset android system setting file, and the permission modification interface can indicate the permission of the terminal to modify the fixed data block, so that the problem that the system cannot normally run due to the fact that the file permission is different from the initial permission is solved.
In the embodiment of the present invention, the preset android system setup file may be denoted as "system/core/include/private/android _ filesystem _ config", and the permission modification interface may include an initial permission of the fixed data block, that is, a file permission that the fixed data block has when the system is partitioned, so that the permission modification interface may instruct the terminal to change the file permission of the fixed data block to the initial permission.
Further, in practical applications, when the terminal performs system upgrade, the terminal calls data in the fixed data block while upgrading according to data in the system upgrade package, so that the data in the system upgrade package has address parameters for calling the data in the fixed data block. In the embodiment of the present invention, the fixed data block is stored in the fixed partition, that is, the storage location of the fixed data block is changed. In order to ensure that the data in the fixed data block can be normally called when the system is upgraded, the address parameters in the system upgrade package can be changed according to the storage path of the fixed data block in the fixed partition. However, since the address parameters are many, the workload of changing the address parameters is large. Therefore, in the embodiment of the present invention, a fixed data block soft link may be generated according to a storage path of a fixed data block in a fixed partition, where the fixed data block soft link carries the storage path of the fixed data block in the fixed partition, and the fixed data block soft link is used to instruct the terminal to call data in the fixed data block according to the storage path when performing system upgrade by using data in the system upgrade package and the fixed data block; then when the system needs to be upgraded, the developer can store the fixed data blocks in corresponding positions in the system upgrade package in a soft link mode. Thus, normal calling can be realized without changing the calling address parameter.
And step 408, when the terminal upgrades the operating system of the terminal by using the system upgrade package, extracting the fixed data file stored in the fixed partition of the terminal.
In this step, the system upgrade package may store the fixed data block soft link corresponding to the fixed data block. Wherein the fixed data block soft link carries a storage path of the fixed data block in the fixed partition. Therefore, in the subsequent upgrading process, the terminal can call the data in the fixed data block according to the soft link of the fixed data block.
Specifically, the step 302 may be referred to for a specific implementation manner of this step, and details are not described herein in this embodiment of the present invention.
And step 410, the terminal carries out system upgrade by using the data in the system upgrade package and the fixed data block.
Specifically, the specific implementation manner of this step may refer to step 303 described above, and details of the embodiment of the present invention are not described herein.
In the android system, when the storage position of the data changes, the operating system changes the file authority of the data with the changed storage position to the lowest authority, so that in the embodiment of the invention, the file authority of the fixed data block changes when the fixed data block is stored in the fixed partition.
In this step, since the development device sets the permission modification interface in the preset android system setting file in advance, the terminal can change the file permission of the fixed data block into the initial permission according to the permission modification interface. For example, assuming that the initial permission is readable and writable, the terminal may change the file permission of the fixed data block to be readable and writable according to the permission modification interface.
It should be noted that, the order of the steps of the system data processing method provided by the embodiment of the present disclosure may be appropriately adjusted, and the steps may also be correspondingly increased or decreased according to the situation. For example, the step 406 may be before the step 405, the step 407 may be before the step 406, and any person skilled in the art can easily think of various methods within the technical scope of the disclosure, which are within the protection scope of the disclosure, and thus, the description thereof is omitted.
In summary, according to another system data processing method provided in the embodiments of the present invention, the development device may establish the fixed partition under the operating system of the terminal, generate the fixed data file according to the fixed data block in the system partition under the operating system, and finally store the fixed data file in the fixed partition. Therefore, when the terminal upgrades the operating system of the terminal by using the system upgrade package, the fixed data file can be extracted from the fixed data partition, and the fixed data block can be obtained after the fixed data file is decompressed. Therefore, in the embodiment of the present invention, when the system upgrade package only includes data for updating the data block to be updated, the terminal may use the fixed data block in the fixed partition to upgrade the system, thereby reducing the data amount in the system upgrade package, reducing the time for a user to download the system upgrade package, and accelerating the efficiency of system upgrade.

Therefore, when the terminal upgrades the operating system of the terminal by using the system upgrade package, the fixed data file can be extracted from the fixed data partition, and the fixed data block can be obtained after the fixed data file is decompressed. Therefore, in the embodiment of the present invention, when the system upgrade package only includes data for updating the data block to be updated, the terminal may use the fixed data block in the fixed partition to upgrade the system, thereby reducing the data amount in the system upgrade package, reducing the time for a user to download the system upgrade package, and accelerating the efficiency of system upgrade.
