[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] The following describes a system upgrade method provided by an embodiment of the present application. Figure 1 A flowchart of a system upgrade method provided for an embodiment of the present application. It should be noted that this specification provides method operation steps as described in the embodiment or flowchart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only order of execution. When the system or product is executed in practice, it can be executed in the order shown in the embodiment or the drawings or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, Figure 1 As shown, the method is applied to a computer system including a file system partition and a data storage partition, and the method may include:

[0030] S101, in response to an upgrade instruction for a file system partition, obtain data association information corresponding to each of a plurality of upgrade data blocks in an upgrade package, wherein the data association information corresponding to each upgrade data block includes: location information of the corresponding upgrade data block in the upgrade package, a first data volume of each upgrade data block being smaller than a storable data volume of the data storage partition, and a second data volume of the upgrade package being larger than the storable data volume.

[0031] In the embodiments of the present specification, the above-mentioned computer system may be a computer system installed in a computer device, which may include but is not limited to: a mobile terminal, a computer terminal, a server or a similar computing device, and the computer system may include: Microsoft Windows system, iOS system, Android system and embedded system, etc., wherein the embedded system may include: Linux system, VxWorks system, uCOS system, FreeRTOS system, RTOS system, etc.

[0032] In a specific embodiment, the above-mentioned computer system may include: U-boot partition, kernel partition, file system partition, recovery partition, data storage partition, etc., wherein the U-boot partition is used to store the uboot image, and the uboot program is mainly responsible for starting the system kernel; the kernel partition is used to store the kernel image, including the system driver, system configuration file, and network environment configuration, etc.; the file system partition is used to store the file system image, including some system built-in programs, third-party library files, etc.; the recovery partition is used to store the system recovery image, which is a temporary file system that contains the necessary drivers, tools and configuration files, and is used to initialize and configure the system before mounting the real root file system after the kernel is started; the data storage partition is used to store data saved by users.

[0033] In a specific embodiment, the upgrade instruction may be an instruction for upgrading the file system. Specifically, a root file system is running in the file system partition, and a main application for interacting with the user is installed in the root file system. The user may initiate an upgrade instruction for the file system partition through the main application.

[0034] In the present embodiment, the upgrade package is an image file corresponding to the new version of the file system. Schematically, the file format of the upgrade package can be .img. Specifically, the data volume of the file system partition can represent the space size of the file system partition, the second data volume can represent the data size of the upgrade package, and the second data volume is usually less than or equal to the data volume of the file system partition. Therefore, the upgrade package can be trimmed based on the data volume of the file system partition so that the second data volume of the completed upgrade package is less than or equal to the data volume of the file system partition. After the upgrade package is completed, it can be stored in a remote server, and the remote server can perform data block processing on the upgrade package so that the computer device can download the upgrade package in blocks.

[0035] In a specific embodiment, before responding to the upgrade instruction, the method may further include: responding to a data storage capacity query request sent by a remote server, sending the storable data volume of the data storage partition to the remote server, so that the remote server determines a first data volume based on the storable data volume, and based on the first data volume, performs data segmentation on the upgrade package to obtain multiple upgrade data blocks.

[0036] Specifically, the amount of data that can be stored in the data storage partition can represent the size of the current available space of the data storage partition, and the first data amount can represent the maximum data size that each upgrade data block in the upgrade package can take, wherein the first data amount < the amount of data that can be stored in the data storage partition < the second data amount of the upgrade package.

[0037] In an optional embodiment, the first data amount can be (0, × the amount of data that can be stored], m can be an integer greater than or equal to 1. Schematically, m can be 5. Preferably, the first data amount can be 1MB.

[0038] Indicatively, Figure 2 As shown, the multiple upgrade data blocks may be n upgrade data blocks, respectively marked as: R1, R2, ..., Rn. In some embodiments, the data volume of the upgrade data blocks R1 to Rn-1 is the first data volume, Rn-1 ≥ Rn, that is, the remote server starts from the starting position of the upgrade package, takes the first data volume as the data block size, and evenly divides the upgrade package to obtain N-1 upgrade data blocks R1 to Rn-1 and Rn of the same size; in other embodiments, max{R1, R2, ..., Rn} ≤ the first data volume, that is, the remote server randomly divides the upgrade package to obtain N upgrade data blocks, wherein the data size of the largest upgrade data block among the N upgrade data blocks is less than or equal to the first data volume.

[0039] It can be seen from the above embodiments that the remote server first queries the computer device for the amount of data that can be stored in the data storage partition, determines the first data amount, and then based on the first data amount, performs data segmentation on the upgrade package to obtain multiple upgrade data blocks. This can ensure that the data amount of each upgrade data block is smaller than the amount of data that can be stored in the data storage partition, thereby avoiding the situation where the data storage partition cannot accommodate a certain upgrade data block.

[0040] In a specific embodiment, the above-mentioned obtaining of data association information corresponding to each of the multiple upgrade data blocks in the upgrade package includes:

[0041] S1011, in response to the upgrade instruction, sending an upgrade information query request to the remote server.

[0042] In an optional embodiment, when the computer system is a Linux system, since the Linux system does not allow the currently running file system to be directly rewritten, it is necessary to restart the device first, switch to the recovery partition to run the reovery system, and then rewrite the file system. Specifically, Figure 3 As shown, after the user initiates the upgrade instruction in the main application, the tag bit tag=recovery is set (indicating that the next time the system is restarted, after the system kernel is loaded, the recovery system is loaded and run from the recovery partition), the computer system is restarted, and after the system kernel is loaded, the recovery system is entered from the recovery partition. The recovery system is configured with an update application, which can be an application or an execution script. The update application sends an upgrade information query request to the remote server.

[0043] S1012, receiving data association information corresponding to each of the multiple upgrade data blocks sent by the remote server based on the upgrade information query request, where the data association information corresponding to each of the multiple upgrade data blocks is association information generated by the remote server after data segmentation of the upgrade package based on the first data volume.

[0044] In a specific embodiment, the data association information corresponding to each upgrade data block may include: identification information of the corresponding upgrade data block, location information of the corresponding upgrade data block in the upgrade package, download address information of the corresponding upgrade data block, data volume information of the corresponding upgrade data block and data summary information of the corresponding upgrade data block. Specifically, the identification information corresponding to each upgrade data block is used to identify and distinguish each upgrade data block. Schematically, the identification information may include: name, number, etc.; the location information of each upgrade data block in the upgrade package may include: starting position and ending position; the data volume information corresponding to each upgrade data block may represent the data size of the corresponding upgrade data block; the data summary information corresponding to each upgrade data block may represent the data fingerprint of the corresponding upgrade data block, so as to realize functions such as data signature and data integrity verification.

[0045] In a specific embodiment, the data summary information corresponding to each upgrade data block is generated by the remote server after performing data summary processing on each upgrade data block based on a first preset encryption algorithm. Optionally, the first preset encryption algorithm here can be a hash algorithm. Schematically, the hash algorithm can include but is not limited to: HMAC-MD5 algorithm, HMAC-SHA256 algorithm, etc. The embodiment of the present application does not impose any restrictions on this.

[0046] S102, scheduling and executing a plurality of data processing tasks in parallel, each data processing task corresponding to an upgraded data block among a plurality of upgraded data blocks.

[0047] In the embodiment of the present specification, the above-mentioned multiple data processing tasks may be data block update tasks constructed based on data association information corresponding to each of the multiple upgraded data blocks; specifically, the above-mentioned update application creates a task pool, which is used to manage the multiple data processing tasks.

[0048] In a specific embodiment, the above-mentioned parallel scheduling and execution of multiple data processing tasks may include:

[0049] S1021, when the number of tasks in the plurality of data processing tasks is greater than the preset parallel number, determine the preset parallel number of currently scheduled tasks from the plurality of data processing tasks, and add the other data processing tasks in the plurality of data processing tasks except the preset parallel number of currently scheduled tasks to a waiting queue.

[0050] Specifically, multiple data processing tasks can be sorted based on the identification information of the upgraded data blocks corresponding to each of the multiple data processing tasks, and the preset parallel number of data processing tasks with the highest sorting can be used as the preset parallel number of currently scheduled tasks, and other data processing tasks can be added to the waiting queue in sequence.

[0051] In a specific embodiment, the preset parallel number is determined based on the ratio of the storable data volume to the first data volume, and the preset parallel number may be an integer less than the ratio.

[0052] S1022: Execute a preset number of currently scheduled tasks in parallel.

[0053] S1023, after any current scheduled task among the preset parallel number of current scheduled tasks is executed, the preset parallel number of current scheduled tasks is updated based on the data processing task that is ranked first in the waiting queue to obtain a preset parallel number of updated scheduled tasks.

[0054] S1024: Based on the preset parallel number of update scheduling tasks, jump to parallel execution of the preset parallel number of current scheduling tasks until the number of tasks in the waiting queue is zero.

[0055] Schematically, the multiple data processing tasks are q data processing tasks, namely: task1 to taskq, the preset parallel number can be 5, task1 to task5 are taken as 5 current scheduled tasks, task1 to task5 are executed in parallel, after any task from task1 to task5 is completed, task6 is added to the current scheduled task to obtain 5 updated scheduling tasks (unfinished tasks from task1 to task5 and task6), and the 5 updated scheduling tasks are continued to be executed in parallel, ... until all q data processing tasks are completed.

[0056] In a specific embodiment, when the number of the multiple data processing tasks is less than or equal to the preset parallel number, the above-mentioned parallel scheduling and execution of the multiple data processing tasks may also include: executing the multiple data processing tasks in parallel.

[0057] It can be seen from the above embodiments that when the number of tasks of multiple data processing tasks is greater than the preset parallel number, a preset parallel number of currently scheduled tasks is determined from the multiple data processing tasks, and other data processing tasks except the preset parallel number of currently scheduled tasks in the multiple data processing tasks are added to the waiting queue, and then the preset parallel number of currently scheduled tasks are executed in parallel, and after any current scheduled task among the preset parallel number of currently scheduled tasks is completed, the preset parallel number of currently scheduled tasks is updated based on the data processing task ranked first in the waiting queue to obtain a preset parallel number of updated scheduling tasks, and then based on the preset parallel number of updated scheduling tasks, jump to the parallel execution of the preset parallel number of currently scheduled tasks until the number of tasks in the waiting queue is zero. By means of task parallel scheduling execution, the system upgrade time can be reduced and the system upgrade efficiency can be improved.

[0058] S103, in the process of parallel scheduling and execution of multiple data processing tasks, in response to the execution instruction for the current scheduled task, when the original data block corresponding to the target upgrade data block is the data block to be updated, the target upgrade data block is downloaded to the data storage partition, and after the original data block in the file system partition is updated based on the target upgrade data block, the target upgrade data block in the data storage partition is deleted; the target upgrade data block is an upgrade data block corresponding to the current scheduled task among the multiple upgrade data blocks, and the original data block corresponding to the target upgrade data block is a data block determined from the file system partition based on the location information of the target upgrade data block in the upgrade package.

[0059] In an optional embodiment, the data association information corresponding to each of the above-mentioned upgraded data blocks may also include: data summary information corresponding to the upgraded data block, such as Figure 4 As shown, the above method may also include:

[0060] S401, in response to an execution instruction for a currently scheduled task, based on location information of a target upgrade data block in an upgrade package, an original data block corresponding to the target upgrade data block is determined from a file system partition, wherein the data volume of the original data block is equal to the data volume of the target upgrade data block.

[0061] In a specific embodiment, the position information of the target upgrade data block in the upgrade package may include: a target start position and a target end position of the target upgrade data block in the upgrade package, and the determining of the original data block corresponding to the target upgrade data block from the file system partition based on the position information of the target upgrade data block in the upgrade package may include:

[0062] The data block corresponding to the starting position of the file system partition and the ending position of the target starting position is used as the original data block corresponding to the target upgrade data block;

[0063] Or, a data block whose corresponding starting position in the file system partition is the target starting position and whose corresponding data volume is the target data volume is used as the original data block corresponding to the target upgrade data block, wherein the target data volume is the data volume of the target upgrade data block.

[0064] S402, performing data summary processing on the original data block to generate data summary information corresponding to the original data block.

[0065] In a specific embodiment, the data summary information corresponding to the original data block can represent the data fingerprint of the original data block to implement functions such as data signature and data integrity verification. Specifically, the data summary information corresponding to the original data block is generated by the computer device (update application) after performing data summary processing on the original data block based on the second preset encryption algorithm, wherein the second preset encryption algorithm is the same encryption algorithm as the above-mentioned first preset encryption algorithm.

[0066] S403, comparing the data summary information corresponding to the target upgraded data block with the data summary information corresponding to the original data block to obtain update indication information, where the update indication information is used to indicate whether the original data block corresponding to the target upgraded data block is a data block to be updated.

[0067] In a specific embodiment, the update indication information may include: first indication information and second indication information, the first indication information is used to indicate that the original data block corresponding to the target upgrade data block is the data block to be updated, and the second indication information is used to indicate that the original data block corresponding to the target upgrade data block is not the data block to be updated. The above-mentioned comparison of the data summary information corresponding to the target upgrade data block and the data summary information corresponding to the original data block to obtain the update indication information may include: when the data summary information corresponding to the target upgrade data block and the data summary information corresponding to the original data block are consistent, determining that the update indication information is the second indication information; when the data summary information corresponding to the target upgrade data block and the data summary information corresponding to the original data block are inconsistent, determining that the update indication information is the first indication information.

[0068] S404, when the update indication information indicates that the original data block corresponding to the target upgrade data block is the data block to be updated, the target upgrade data block is downloaded to the data storage partition, and after the original data block in the file system partition is updated based on the target upgrade data block, the target upgrade data block in the data storage partition is deleted.

[0069] Specifically, when the update indication information indicates that the original data block corresponding to the target upgrade data block is the data block to be updated, the target upgrade data block is downloaded to the data storage partition, and the corresponding original data block in the file system partition is flushed based on the target upgrade data block in the data storage partition. When the flushing is completed, it is considered that the update of the original data block is completed, and then the target upgrade data block in the data storage partition is deleted.

[0070] In a specific embodiment, the data association information corresponding to each upgrade data block may further include: download address information of the corresponding upgrade data block, and based on the download address information of the target upgrade data block, download the target upgrade data block to the data storage partition.

[0071] In an optional embodiment, when the update indication information indicates that the original data block corresponding to the target upgraded data block is not the data block to be updated, the current scheduling task is terminated and the data processing task with the highest order in the current waiting queue is continued to be executed.

[0072] Indicatively, the preset parallel quantity can be 5, and the multiple upgraded data blocks are R1 to Rn, and correspondingly, the multiple data processing tasks are: task1 corresponding to R1, task2 corresponding to R2, ... taskn corresponding to Rn, and task1 to task5 are used as 5 current scheduled tasks, and tasks1 to task5 are executed in parallel. After any task from task1 to task5 is completed, task6 is added to the current scheduled task to obtain 5 updated scheduled tasks (unfinished tasks from task1 to task5 and task6), and the 5 updated scheduled tasks are continued to be executed in parallel, and so on... until all n data processing tasks are completed, where taskx (x = 1, 2, ..., n ) includes: based on the location information of the upgrade data block Rx in the upgrade package, determining the original data block Dx corresponding to the upgrade data block Rx from the file system partition, reading the data summary information of the upgrade data block R1, and calculating the data summary information of the original data block Dx. If the two are equal, it means that the original data block Dx does not need to be updated, and taskx is terminated, and the data processing task at the front of the current waiting queue is continued; if the two are not equal, it means that the original data block Dx needs to be updated, and the download address information of the upgrade data block Rx is read and the upgrade data block Rx is downloaded to the data storage partition. After the download is completed, the upgrade data block Rx in the data storage partition is flushed to the original data block Dx in the file system partition. After the flushing is completed, the upgrade data block Rx file is deleted.

[0073] It can be seen from the above embodiments that in response to the execution instruction for the current scheduled task, based on the location information of the target upgrade data block in the upgrade package, the original data block corresponding to the target upgrade data block is determined from the file system partition, and the data volume of the original data block is equal to the data volume of the target upgrade data block. Then, the data summary information corresponding to the target upgrade data block and the data summary information corresponding to the original data block are compared to obtain the update indication information. When the update indication information indicates that the original data block corresponding to the target upgrade data block is the data block to be updated, the target upgrade data block is downloaded to the data storage partition. After the original data block in the file system partition is updated based on the target upgrade data block, the target upgrade data block in the data storage partition is deleted. Only the upgrade data block corresponding to the original data block to be updated can be downloaded, thereby updating the original data block to be updated in the file system partition, which can save network resources and reduce the storage-related device hardware costs.

[0074] In an optional embodiment, the data association information corresponding to each of the above-mentioned upgraded data blocks may also include: data summary information corresponding to the upgraded data block, such as Figure 5 As shown, before the above-mentioned parallel scheduling execution of multiple data processing tasks, the above-mentioned method may also include:

[0075] S501, based on the location information corresponding to each of the multiple upgraded data blocks, data segmentation is performed on the file system partition to obtain multiple original data blocks and data summary information corresponding to each of the multiple original data blocks, each original data block corresponds to an upgraded data block among the multiple upgraded data blocks, and the data volume of each original data block is equal to the data volume of the upgraded data block corresponding to each original data block.

[0076] In a specific embodiment, the data segmentation of the file system partition based on the location information corresponding to each of the multiple upgraded data blocks to obtain the multiple original data blocks and the data summary information corresponding to each of the multiple original data blocks may include:

[0077] S5011, traverse multiple upgrade data blocks.

[0078] S5012: Based on the location information of the currently traversed upgrade data block in the upgrade package, determine the original data block corresponding to the currently traversed upgrade data block from the file system partition.

[0079] Specifically, the detailed content of step S5012 is similar to the detailed content of step S401, and will not be repeated here.

[0080] S5013, performing data summary processing on the original data block corresponding to the currently traversed upgraded data block to obtain data summary information of the original data block corresponding to the currently traversed upgraded data block.

[0081] Specifically, the detailed content of step S5013 is similar to the detailed content of step S402, and will not be repeated here.

[0082] S5014, after traversing the multiple upgraded data blocks, obtain the multiple original data blocks and the data summary information corresponding to each of the multiple original data blocks.

[0083] S502 : Compare the data summary information corresponding to each upgraded data block with the data summary information of the original data block corresponding to each upgraded data block, and determine a plurality of data blocks to be updated among the plurality of original data blocks.

[0084] Specifically, the data summary information corresponding to each upgraded data block is compared with the data summary information of the original data block corresponding to each upgraded data block, and the original data blocks with inconsistent corresponding comparison results among the multiple original data blocks are used as the multiple data blocks to be updated.

[0085] S503: Create data update tasks corresponding to multiple data blocks to be updated.

[0086] S504: The data update tasks corresponding to the multiple data blocks to be updated are used as multiple data processing tasks.

[0087] Schematically, the upgrade package is divided into 10 upgrade data blocks: R1 to R10, and correspondingly, the file system partition is divided into 10 original data blocks: D1 corresponding to R1, D2 corresponding to R2, ... D10 corresponding to R10, among which the data summary information of R1 and D1 is inconsistent, the data summary information of R2 and D2 is inconsistent, the data summary information of R3 and D3 is inconsistent, the data summary information of R5 and D5 is inconsistent, the data summary information of R8 and D8 is inconsistent, and the data summary information of R9 and D9 is inconsistent. Therefore, data update tasks corresponding to the original data blocks D1, D2, D3, D5, D8 and D9 are created, and the 6 data update tasks are scheduled and executed in parallel. Taking the preset parallel number of 3 as an example, the data update task 1 corresponding to D1, the data update task 2 corresponding to D2 and the data update task 3 corresponding to D3 are executed in parallel. After any of the data update tasks 1 to 3 is completed, the data update task 4 corresponding to D5 is executed, and so on... until all 6 data update tasks are completed. The task content of each data update task includes: reading the download address information of the corresponding upgraded data block Ri and downloading the upgraded data block Ri to the data storage partition. After the download is completed, the upgraded data block Ri of the data storage partition is flushed to the original data block Di in the file system partition. After the flushing is completed, the upgraded data block Ri file is deleted.

[0088] It can be seen from the above embodiments that the file system partition is firstly segmented based on the position information corresponding to each of the multiple upgrade data blocks to obtain multiple original data blocks, and then multiple data blocks to be updated are determined among the multiple original data blocks, and then data update tasks corresponding to each of the multiple data blocks to be updated are constructed. In the process of parallel scheduling and execution of multiple data update tasks, the upgrade data blocks corresponding to each data update task are downloaded, so as to update the original data blocks corresponding to each data update task, which can effectively improve the efficiency of parallel scheduling and execution of tasks and reduce the system upgrade time.

[0089] S104, after the execution of the multiple data processing tasks is completed, an upgraded file system partition is obtained.

[0090] In an optional embodiment, when the second data volume is smaller than the data volume of the file system partition, the upgraded file system partition obtained after the execution of the multiple data processing tasks may include:

[0091] S1041, after the execution of the plurality of data processing tasks is completed, redundant data blocks are erased in the current file system partition to obtain an upgraded file system partition, wherein the redundant data blocks are original data blocks in the file system partition that do not correspond to any upgraded data blocks.

[0092] Specifically, the data volume of the file system partition can represent the space size of the file system partition. The second data volume of the upgrade package is usually less than or equal to the data volume of the file system partition. Figure 6 As shown, in the case where the second data volume of the upgrade package is usually smaller than the data volume of the file system partition, it is necessary to erase the original data blocks that do not correspond to any upgrade data blocks in the current file system partition to ensure that the data content in the current file system partition is consistent with the data content of the upgrade package.

[0093] In an optional embodiment, when the computer system is a Linux system, since the Linux system does not allow direct flashing of the currently running file system, it is necessary to restart the device first, switch to the recovery partition to run the reovery system, and then flash the file system. After the flashing is completed, that is, after multiple data processing tasks are executed, set the mark bit tag=boot, restart the computer system again to enter the main system, and complete the upgrade.

[0094] It can be seen from the technical solutions provided by the above embodiments of this specification that in an application scenario of upgrading a file system partition of a computer system, data association information corresponding to each of a plurality of upgrade data blocks in an upgrade package is first obtained, and the data association information corresponding to each upgrade data block includes: location information of the corresponding upgrade data block in the upgrade package, a first data volume of each upgrade data block is smaller than a storable data volume of the data storage partition, and a second data volume of the upgrade package is larger than the storable data volume, and then a data processing task is determined based on the data association information corresponding to each of the plurality of upgrade data blocks, and in the process of parallel scheduling execution of the plurality of data processing tasks, in response to an execution instruction for a currently scheduled task, a query is made in the file system partition for a corresponding upgrade data block corresponding to a target upgrade data block of the currently scheduled task. Whether the original data block needs to be updated, if the original data block is the data block to be updated, the target upgrade data block is downloaded to the data storage partition, and after the original data block in the file system partition is updated based on the target upgrade data block, the target upgrade data block in the data storage partition is deleted. Finally, after the execution of multiple data processing tasks, the upgraded file system partition is obtained. Since only the upgrade data blocks corresponding to the original data blocks to be updated in multiple upgrade data blocks need to be downloaded during the entire file system partition upgrade process, and the tasks are scheduled and executed in parallel, the system upgrade time can be reduced and the system upgrade efficiency can be improved. At the same time, since the upgrade package is downloaded in blocks, only a small-capacity data storage partition is needed for data block storage, which can effectively reduce the device hardware cost.
