Detailed Description
As described in the background art, in the prior art, if power failure occurs during the differential upgrade process, the problem that the terminal cannot be started after the power failure may occur.
The inventor of the invention finds out through research that the problem that the terminal equipment cannot be started after power failure in the prior art is mainly caused by small local storage capacity of the terminal equipment, and the small storage space is insufficient for backing up the original version file to be upgraded. Specifically, before the original version file is upgraded, the original version file is usually backed up to the free storage space of the terminal, and if the backup is successful, the original version file and the differential packet in the free storage space of the terminal can be used to continue to be upgraded if the process of upgrading the original version file is interrupted due to power failure and the like. However, if the free storage space of the terminal is small and the original edition file cannot be backed up, the upgrade process cannot be continued after being interrupted.
In order to solve the above technical problem, an embodiment of the present invention provides a differential upgrading method, where the method includes: acquiring a differential packet for upgrading an original version file, wherein the differential packet comprises a plurality of differential sub-packets, each differential sub-packet is used for upgrading a corresponding original version file block in the original version file, and the sum of the size of the original version file block and the size of the differential packet does not exceed the size of a local free storage space of a terminal; and upgrading the original edition file for multiple times by using the differential sub-packet, and upgrading the corresponding original edition file block by using a single differential sub-packet each time. In the scheme provided by the embodiment of the invention, the obtained differential packet for upgrading the original edition file comprises a plurality of differential sub-packets, and each differential sub-packet is used for upgrading a corresponding original edition file block in the original edition file, so that the original edition file can be upgraded for multiple times, and a single original edition file block is upgraded each time; the sum of the size of the original version file block and the size of the differential packet does not exceed the size of the local free storage space of the terminal, so that the local free storage space of the terminal can back up the original version file block when a single original version file block is upgraded, and if the upgrading process of the original version file block is interrupted, the original version file block in the local free storage space can be used for continuing upgrading when the upgrading process is recovered.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flow chart of a differential upgrading method according to an embodiment of the present invention. The differential upgrading method may be executed by a terminal, and may be used to upgrade a version of a terminal system program (e.g., an operating system, an application program, and the like), where the terminal may be a terminal device such as a computer, a mobile phone, a smart watch, and an internet of things device, but is not limited thereto. The difference package required for the difference upgrade of the system program may be made by an internal server, which may be an internal server of the system program provider, but is not limited thereto. After the internal server creates the difference packet required for completing the system program difference upgrade, the difference packet may be transmitted to an external server for storage, and the external server may be an external server of a system program provider, but is not limited thereto. The external server may be coupled to a terminal, and the terminal may obtain the differential packet from the external server for differential upgrade. The differential upgrade may be a differential upgrade in an OTA. The differential upgrade method shown in fig. 1 may include the following steps:
step S101: acquiring a differential packet for upgrading an original version file, wherein the differential packet comprises a plurality of differential sub-packets, each differential sub-packet is used for upgrading a corresponding original version file block in the original version file, and the sum of the size of the original version file block and the size of the differential packet does not exceed the size of a local free storage space of a terminal;
step S102: and upgrading the original edition file for multiple times by using the differential sub-packet, and upgrading the corresponding original edition file block by using a single differential sub-packet each time.
In the specific implementation of step S101, when the terminal needs to upgrade the terminal system program, the differential packet required for upgrading may be obtained from the external server. The differential packet may be made by the internal server.
Further, in the differential packet making process, the internal server may block the original version file according to the size of the local free storage space of the terminal, so that the size of the original version file block and the size of the differential packet do not exceed the local free storage space of the user terminal.
Specifically, the internal server stores an original version file and a new version file of a system program that the terminal wants to upgrade, and the internal server may generate a difference package required by the original version file by: the method comprises the following steps: the internal server determines an original edition file and a corresponding new edition file which need to be upgraded; step two: the internal server sets the size of the data block, divides the original edition file into a plurality of original edition file blocks, and the size of each original edition file block is equal to the size of the data block; step three: for each original edition file block, the internal server generates a differential sub-package required by the upgrade of the original edition file block according to the new edition file block; step four: determining the size of a local free storage space of the terminal; step five: and judging whether the sum of the size of the original edition file block and the size of the differential packet exceeds the size of a local free storage space of the terminal, if so, returning to the step two, and if not, sending the differential packet to the terminal, wherein the differential packet comprises all differential sub-packets.
The internal server may also execute step four before step two, that is, the size of the local free storage space of the terminal may be determined first, and then the size of the data block may be set.
Further, the internal server may receive the size of the local free storage space of the terminal from the external server, or may determine the size of the local free storage space of the terminal according to a preset value. The size of the local free storage space of the terminal received from the external server may be the size of the real-time local free storage space of the terminal, and if there are a plurality of terminals that need to upgrade the system program, the size of the local free storage space of the terminal received from the external server may also be a value determined by the external server after calculating the size of the local free storage space reported by each terminal, for example, an average value of the sizes of the local free storage spaces reported by each terminal.
From the above, the internal server determines, through circulation, whether the sum of the size of the original version file block and the size of the differential packet exceeds the size of the local free storage space of the terminal, so that the sum of the size of the original version file block and the size of the differential packet does not exceed the size of the local free storage space of the terminal while generating the differential packet required by the upgrade of the original version file block. The differential packet made by the internal server comprises all differential sub-packets and can also comprise the size information of the original version file block.
Furthermore, after the internal server completes the manufacture of the differential packet, the differential packet can be actively sent to the external server for the terminal to download. After the internal server finishes the manufacture of the differential packet, the differential packet can not be sent to the external server actively, when the terminal needs to upgrade the terminal system program, a differential packet downloading request can be sent to the external server, and the external server can obtain the differential packet from the internal server after receiving the differential packet downloading request and then transmit the differential packet to the terminal.
Furthermore, before the terminal upgrades the original version file, the differential packet may be downloaded from the external server to the local free storage space, and then the differential packet is used to upgrade the local original version file of the terminal.
Further, the differential packet in the embodiment of the present invention may include a plurality of differential sub-packets, and each differential sub-packet is used to update a corresponding original version file block in the original version file. The terminal can upgrade the corresponding original version file blocks by using the differential sub-packets in sequence until all the original version file blocks are upgraded. That is, the original version file in the embodiment of the present invention includes a plurality of original version file blocks, and the upgrade process of the original version file may be equivalent to the upgrade process of all the original version file blocks. The original version file block may be a file block divided before the original version file is upgraded, or may be a file block formed by reading a part of the original version file to be upgraded from a storage area of the original version file each time during the process of upgrading the original version file, but is not limited thereto.
In one non-limiting embodiment, the master file may contain a plurality of master version partition files, such as boot (boot) partition files, etc., and the master file blocks may be part of the master version partition files.
Furthermore, the differential sub-packets have a one-to-one correspondence relationship with the original version file blocks, each differential sub-packet is an upgrade packet required by upgrading the corresponding original version file block, and each differential sub-packet can be used for upgrading the corresponding original version file block in the original version file. The differential sub-packet can be obtained by performing differential manufacturing on the original version file block and the corresponding new version file block, and can also be obtained by manufacturing based on other differential algorithms.
Further, before upgrading the original version file, the terminal may download the differential packet to the local free storage space of the terminal, and when upgrading each original version file block, the corresponding differential sub-packet may be read from the local free storage space of the user terminal, and based on the original version file block and the corresponding differential sub-packet, the original version file block is upgraded, for example, by calling a patch command.
Further, the local free storage space of the terminal may be used to store the differential packet, and may also be used to store the original version file block, but is not limited thereto. When the original version file blocks are upgraded, the terminal can back up the original version file blocks to a local free storage space of the terminal, and because the difference packet made by the internal server contains the size information of the original version file blocks, and the sum of the size of the original version file blocks and the size of the difference packet does not exceed the local free storage space of the terminal, when each original version file block is upgraded, the original version file blocks can be backed up to the local free storage space, and the situation that the original version file blocks cannot be backed up due to the fact that the local free storage space of the terminal is insufficient can be avoided.
In a specific implementation of step S102, the differential sub-packet is used to update the original version file multiple times, and each time a single differential sub-packet is used to update a corresponding original version file block.
As described above, the differential sub-packets in the embodiments of the present invention include the differential sub-packets required for upgrading the original version file blocks, and the terminal may sequentially use the differential sub-packets to upgrade the corresponding original version file blocks in the process of upgrading the original version file until the original version file is upgraded.
Further, the differential packet may further include size information of the original version file block, and the multiple upgrades to the original version file using the differential packet may include: and when the terminal upgrades one original edition file block every time, acquiring the original edition file block to be upgraded from the original edition file according to the size information of the original edition file block in the differential sub-packet, and upgrading the original edition file block by using the corresponding differential sub-packet. In the process of upgrading the original version file block, the original version file block to be upgraded at this time can be backed up to the local free storage space of the terminal.
Furthermore, because the size of the original edition file block meets the condition that the sum of the size of the original edition file block and the size of the differential packet does not exceed the local free storage space of the terminal, the original edition file block to be upgraded at this time can be backed up to the local free storage space of the user terminal in the process of upgrading each original edition file block, and if the upgrading process of the original edition file is interrupted and the original edition file block is damaged when the upgrading process is recovered, the original edition file block to be upgraded can be continuously upgraded by using the backed up original edition file block.
Therefore, in the scheme provided by the embodiment of the present invention, the obtained differential packet for upgrading the original version file includes a plurality of differential sub-packets, and each differential sub-packet is used for upgrading a corresponding original version file block in the original version file, so that the original version file can be upgraded for multiple times, and a single original version file block is upgraded each time; the sum of the size of the original version file block and the size of the differential packet does not exceed the size of the local free storage space of the terminal, so that when a single original version file block is upgraded, the local free storage space of the terminal can be used for storing the differential packet and backing up the original version file block, and if the upgrading process of the original version file block is interrupted, the original version file block in the local free storage space can be used for upgrading continuously when the upgrading process is recovered.
In a non-limiting embodiment, the upgrade state of the original version file block to be upgraded at this time is recorded every time of upgrading. For example, but not limited to, a status file may be created, and upgrade status information of each block of the original version file to be upgraded may be recorded.
Referring to table 1, table 1 shows the upgrade status of the original version file block to be upgraded at different stages in the upgrade process.
TABLE 1
If the upgrading process of the original version file block is interrupted, when the interruption reason is removed, if the power is turned on again, the upgrading process of the original version file block to be upgraded at this time can be recovered, and further, the next step of upgrading the original version file to be upgraded at this time after the upgrading process is recovered can be determined according to the recorded upgrading state of the original version file block to be upgraded at this time, so that the upgrading can be continued. Referring to fig. 2, fig. 2 is a schematic view illustrating a scenario of a differential upgrade method according to an embodiment of the present invention.
If the upgrading process of the original version file block to be upgraded is interrupted, executing step S201, and recovering the upgrading process of the original version file block to be upgraded; and then, executing step S202, detecting the upgrade state of the original version file to be upgraded this time, and if detecting that the upgrade state of the original version file block to be upgraded this time is the start state, executing step S203, and backing up the original file block to be upgraded this time to the local free storage space.
Specifically, if the original version file block to be upgraded at this time enters the upgrading process and is not backed up to the local free storage space, the upgrading state of the original version file block to be upgraded at this time is recorded as the starting state; when the upgrading process is recovered, if the upgrading state of the original version file block to be upgraded at this time is detected to be the starting state, backing up the original file block to be upgraded to the local free storage space, wherein the recovering of the upgrading process is performed after the upgrading process is interrupted.
Further, backing up the original file block to be upgraded to the local free storage space may include: and acquiring the original version file block to be upgraded at this time from the original version file according to the size information of the original version file block, and writing the acquired original version file block to be upgraded at this time into the local idle storage space.
And if the upgrade state of the original version file block to be upgraded is detected to be the backup state, executing the step S204, skipping the backup step, and upgrading the original version file block to be upgraded.
Specifically, if the original version file block to be upgraded at this time is backed up to the local free storage space in the upgrading process and the upgraded new version file is not generated, the upgrading state of the original version file block to be upgraded at this time is recorded as the backup state; and when the upgrading process is recovered, if the upgrading state of the original version file block to be upgraded is detected to be the backup state, skipping the backup step and upgrading the original version file block to be upgraded, wherein the recovery of the upgrading process is performed after the upgrading process is interrupted.
Further, upgrading the original version file block to be upgraded at this time may include: reading a differential sub-packet corresponding to the original version file block to be upgraded at this time from a local free storage space of the terminal, and upgrading the original version file block based on the original version file block and the differential sub-packet corresponding to the original version file block, for example, upgrading by calling a patch command, wherein the upgrading process of the original version file block can be completed in an operating memory of the terminal. It should be noted that the upgrading of the original version file block may be performed by reading the original version file block in the system program storage area, or may be performed by reading the original version file block in the local idle storage area, and the corresponding new version file block obtained after upgrading may cover the original version file block in the system program storage area.
If the upgrade state of the original version file block to be upgraded at this time is detected to be the update state, step S205 is executed to delete the original file block in the local free storage space.
Specifically, if the new version file after the original version file block to be upgraded is upgraded in the upgrading process is generated and the original version file block backed up in the local free storage space is not deleted, the upgrading state of the original version file block to be upgraded is recorded as the updating state; and when the upgrading process is recovered, if the upgrading state of the original version file block to be upgraded at this time is detected to be the updating state, deleting the original file block in the local free storage space, wherein the recovering of the upgrading process is performed after the upgrading process is interrupted.
If the upgrade state of the original version file block to be upgraded is detected to be the complete state, step S206 is executed to determine whether the upgrade of the original version file to which the original version file block to be upgraded belongs is complete, if the upgrade of the original version file is complete, the upgrade process of the original version file is ended, and if the upgrade of the original version file is not complete, the upgrade process of the original version file block to be upgraded next time is started.
Specifically, if the new version file after the original version file block to be upgraded is upgraded in the upgrading process is generated and the original version file block backed up in the local free storage space is deleted, the upgrading state of the original version file block to be upgraded is recorded as a completion state; when the upgrading process is recovered, if the upgrading state of the original version file block to be upgraded at this time is detected to be the finished state and the upgrading of the original version file is not finished yet, starting the upgrading process of the original file block to be upgraded at the next time, wherein the recovering of the upgrading process is carried out after the upgrading process is interrupted. Therefore, in the embodiment of the present invention, the upgrade status of the current original version file block to be upgraded is recorded each time the original version file block is upgraded, and if the upgrade process of the original version file block is interrupted, the next step of the upgrade process can be determined according to the upgrade status of the current original version file block to be upgraded when the upgrade process is resumed, so as to continue the upgrade process of the original version file block without restarting the upgrade process of the original version file block or restarting the upgrade process of the original version file to which the original version file block belongs.
Referring to fig. 3, fig. 3 is a flowchart illustrating another differential upgrade method according to an embodiment of the present invention. The other differential upgrading method may be executed by an internal server, and may be used to upgrade a version of a terminal system program, where the terminal may be a terminal device such as a computer, a mobile phone, a smart watch, and an internet of things device, but is not limited thereto. The internal server may be a server for making a differential package required for a differential upgrade of a terminal system program, and may be, for example, an internal server of a system program provider. After the internal server makes the differential packet required by the system program differential upgrade, the differential packet can be transmitted to the external server for storage. The external server may be coupled to the terminal, and the external server may be an external server of a system program provider, but is not limited thereto. The terminal can obtain the differential packet from the external server to perform differential upgrading. The differential upgrade may be a differential upgrade in an OTA.
The differential upgrade method shown in fig. 3 may include the following steps:
step S301: determining an original edition file and a new edition file;
step S302: setting the size of a data block, and dividing the original version file into a plurality of original version file blocks, wherein the size of each original version file block is equal to the size of the data block;
step S303: for each original version file block, generating a differential sub-packet corresponding to the original version file block according to the new version file;
step S304: determining the size of a local free storage space of the terminal;
step S305: and judging whether the sum of the size of the original edition file block and the size of the differential packet exceeds the size of the local free storage space, if so, returning to the step S302, and if not, sending the differential packet to the terminal, wherein the differential packet comprises all differential sub-packets.
In the specific implementation of step S301, the internal server stores the original edition file and the new edition file of the system program, and the original edition file and the new edition file can be determined according to the system program required to be upgraded. The internal server can actively determine the original version file and the new version file of the system program needing to be upgraded, and can also receive information of the system program needing to be upgraded from the external server, such as the name and the number of the system program, and then determine the original version file and the new version file according to the system program needing to be upgraded.
In the specific implementation of step S303, the new version file may be partitioned according to the size of the data block set in step S302, and the new version file is partitioned into a plurality of new version file blocks, where the new version file blocks have a one-to-one correspondence relationship with the original version file blocks.
Furthermore, the difference between the original version file block and the corresponding new version file block can be performed to generate a differential sub-packet required by the upgrade of the original version file block, and the differential sub-packets required by the upgrade of all the original version file blocks form a differential packet required by the upgrade of the original version file.
In the specific implementation of step S304, the internal server may determine the local free storage space of the terminal that needs to perform system program upgrade according to a preset value, where the preset value may be determined according to the size of the original file and the local maximum storage space of the terminal. The internal server may also receive information of the size of the local free storage space of the terminal from the external server. Specifically, the external server may detect the size of the local free storage space of the terminal in real time, and the size of the local free storage space of the terminal received from the external server may be the size of the local free storage space of the terminal detected by the external server in real time. The terminal may also report the size of its own local free storage space to the external server periodically, and if there are multiple terminals, the size of the local free storage space of the terminal received from the external server may also be a value determined by the external server after calculating the local free storage space reported by each terminal, for example, may be an average value of the sizes of the local free storage spaces reported by each terminal.
It should be noted that step S304 may also be executed before step S302 is executed, that is, the size of the local free storage space of the terminal may be determined first, and then the size of the data block may be set. For example, the size of the data block can be set by adopting a dichotomy according to the size of the local free storage space of the terminal.
In the specific implementation of step S305, if the sum of the size of the original version file block and the size of the differential packet in step S302 exceeds the size of the local free storage space of the terminal, the process returns to step S302, and steps S302 to S305 are repeated until the sum of the size of the original version file block and the size of the differential packet does not exceed the size of the local free storage space of the terminal. And when the step S302 is returned every time, resetting the size of the data block, dividing the original edition file according to the reset size of the data block, and continuing to execute the steps S302 to S305, if the sum of the size of the original edition file block and the size of the differential packet still exceeds the size of the local free storage space of the terminal, returning to the step S302, and resetting the size of the data block again until the sum of the size of the original edition file block and the size of the differential packet does not exceed the size of the local free storage space of the terminal.
Further, the transmitting the differential packet to the terminal may include: and uploading the differential packet to an external server, and transmitting the differential packet to the terminal by the external server.
Specifically, after the differential packet is made, the internal server can actively send the differential packet to the external server for downloading by the terminal. In one non-limiting embodiment, after the internal server uploads the differential packet to the external server, the external server may notify the terminal to download the differential packet for upgrading.
The internal server may not actively send the differential packet to the external server, when the terminal needs to upgrade the system program, the internal server may send a differential packet download request to the external server, and the external server may obtain the differential packet from the internal server after receiving the differential packet download request and then transmit the differential packet to the terminal.
In the embodiment of the present invention, for each original version file block, a differential sub-packet corresponding to the original version file block is generated according to the new version file, so that a differential sub-packet required for upgrading each original version file block can be obtained, and in addition, since the original version file is divided according to the set size of the data block, the size of the original version file block can be adjusted so that the sum of the size of the original version file block and the size of the differential sub-packet does not exceed the size of the local free storage space of the terminal, in the process of upgrading each original version file block, the local free storage space can back up the original version file block to be upgraded this time, thereby implementing power down protection for upgrading the original version file block, and thus implementing power down protection for upgrading the whole original version file.
Those skilled in the art will understand that the differential packet sent to the terminal in step S305 may be used for differential upgrade of the original version file in the embodiment shown in fig. 1, and the differential packet may include the differential sub-packet required for upgrade of the original version file block in the embodiment shown in fig. 1 and the size information of the original version file block.
