Detailed ways

In order to provide an implementation scheme for ensuring that the terminal device can adopt the differential upgrade, the embodiment of the present application provides a method, an apparatus, and a system for differential upgrade. The embodiments provided by the present application are described below with reference to the accompanying drawings.

In order to make the description of the technical solution of the present application easy to understand, the concept of the name involved in the present application is first introduced below.

The original version of the system refers to the system installed on the terminal device before the terminal device is updated, for example, emui5.0.

The target version of the system refers to the system installed on the terminal device after the terminal device is updated, for example, emui8.0.

The system actually used refers to the system actually used on the terminal device before the terminal device is updated. The system actually used has the same system version as the original version of the system, for example, both are emui5.0. If the original version of the system is installed on the terminal device, the data in the system is modified during the use process, resulting in the actual use of the system; if the original version of the system is installed on the terminal device, the In the process, no modifications were made to the system, and the actual system used was the same as the original version.

The upgrade of the system refers to the process of updating the system used by the terminal device from the original version to the target version.

Differential upgrade refers to the process of implementing the system based on the data difference between the system before the upgrade and the system of the target version after the upgrade.

The upgrade object refers to the object that has data difference with the target version of the system in the original version of the system. The server stores the system of the original version before the upgrade of the terminal device, and also stores the system of the target version after the upgrade of the terminal device, compares the system of the original version with the system of the target version, and determines the system of the original version, and The target version of the system has data difference objects, that is, the upgrade target of the system differential upgrade for the terminal device. Specifically, the upgrade object can be a file or a block.

Raw data refers to the data in the system of the original version of the system at the time of installation.

Current data refers to the data in the system actually used.

Repair data refers to the original data of the upgrade object in the original version of the system.

The repair data packet refers to the data packet sent by the server to the terminal device before the differential upgrade, which is used to repair the system actually used. The data corresponding to the upgrade object in the repaired system is the same as the system installed in the original version of the system. Some of the data is exactly the same.

A differential upgrade package refers to a data packet sent by a server to a terminal device to implement differential upgrade of the terminal device.

The OTA differential upgrade technology is a technology that implements system upgrade based on the difference between the original version of the system before the upgrade and the data of the target version after the upgrade. When using OTA differential upgrade, the server only sends a differential upgrade package to the terminal device. The differential upgrade package can reflect the data difference between the original version of the system and the target version of the system. For example, the original version of the system includes data a, b, and c. The target version of the system includes data a, b, c', and the differential upgrade package includes data c'. That is to say, the OTA differential upgrade is based on the original version of the system. Therefore, when the OTA differential upgrade is applied to the terminal device, the upgrade target of the terminal device is not modified. The upgrade target refers to the terminal device. In the original version of the system, there is a difference in data from the target version of the system. For example, the original version of the system includes file A, file B, and file C. The target version of the system includes file A, file B, and file C'. The object is file C. If the system used by the terminal device has been cracked, or an eMMC (embedded multi media card) data hopping occurs, the system data of the original version used by the terminal device is changed, and if the terminal device is upgraded, If the data changes, the data foundation of the OTA differential upgrade changes, and the differential upgrade package cannot be used for differential upgrade.

In order to solve the above problem, the embodiment of the present application provides an implementation solution of a differential upgrade, where the terminal device obtains the repair data of the upgrade object, where the repair data is the original data of the upgrade object in the original version of the terminal device, and uses the repair data. The system actually used by the terminal device is repaired, and the repaired system is obtained. The repaired system is consistent with the original version of the system, and the repaired system is differentially upgraded, and the repaired system is upgraded from the original version to the target version. In the embodiment of the present application, the system of the terminal device is first repaired, the system of the terminal device is restored to be consistent with the original version of the system, and the system of the repaired terminal device is differentially upgraded to ensure that the system is upgraded by using a differential upgrade mode. Effectiveness.

The system of the embodiment of the present application is first introduced. Referring to FIG. 1 in detail, the system includes: a server 100 and a terminal device 110. The server 100 includes a system of the original version of the terminal device 110 and a system of the target version. The server 100 can compare the system of the original version with the system of the target version, determine the upgrade object, and obtain the upgrade object from the original version of the system. The repair data is sent to the terminal device 110 for the repair data of the upgrade object. The terminal device 110 repairs the system by using the repair data of the upgrade object, and then performs differential upgrade on the repaired system. Specifically, the server 100 may be an application service provider or a terminal device provider; the terminal device 110 may be a PDA (Personal Digital Assistant) or a POS (Point of Sales) such as a mobile phone, a tablet computer, a smart watch, a smart TV, or the like. , sales terminal), car computer, TV, wearable device, AR, VR device, etc.

The embodiments of the present application are described in detail below with reference to the accompanying drawings.

FIG. 2 is a flowchart of a method for differential upgrade according to an embodiment of the present application, including the following steps:

Step 201: The server acquires a system of the original version before the terminal device is upgraded, and a system of the upgraded target version.

Step 202: The server determines, according to the system of the original version and the system of the target version, the upgrade object, where the upgrade object is an object of the original version, and the data of the target version is different.

In the system of the terminal device, in order to continuously meet the needs of the end user and modify some bugs, the version of the system is continuously updated, and the version of the system of the terminal device before the update is called the original version, and the system of the updated terminal device is updated. The version is called the target version. The process of updating the system of the terminal device from the original version to the target version is the upgrade of the system. The upgrade message of the system may be sent by the server to the user, or may be obtained by the terminal device querying the server.

The server stores the system of the original version before the upgrade of the terminal device, and also stores the system of the target version after the upgrade of the terminal device, compares the system of the original version with the system of the target version, and determines the system of the original version, and The target version of the system has data difference objects, that is, the upgrade target of the system differential upgrade for the terminal device.

If the upgrade type of the upgrade object is replacement, that is, the upgrade object exists in the system of the original version and the target version, but the data in the upgrade object differs between the system of the original version and the system of the target version. For example, the server compares and finds that the object A is included in the system of the original version of the terminal device, and the target version of the system also includes the object A. If the data in the object A is different, the object A is determined to be the upgrade object, and the upgrade object is The upgrade type of A is replacement.

If the type of the upgrade object is Delete, that is, the upgrade object exists in the original version of the system and does not exist in the target version of the system. For example, the server compares and finds that the object A is included in the system of the original version of the terminal device, and the object A does not include the object A in the target version, and the object A is determined to be the upgrade object, and the upgrade type of the upgrade object A is increased.

In addition, there is a possibility that the upgrade type of the upgrade is increased, that is, the objects existing in the target version of the system do not exist in the original version of the system. That is to say, this kind of differential upgrade is to add an object based on the original version of the system, and the added object is not an object in the original version of the system, so it cannot be used as an upgrade object. For example, the server compares and finds that the object A is included in the system of the target version of a terminal device, but the object A is not included in the original version of the system, and it can be determined that the type of the upgrade is increased, but because the object A is in the original version of the system. Does not exist in it, object A cannot be used as an upgrade object.

In the specific implementation, the upgrade object can be a file, or a block in the file, wherein the block is generally 4K=4096 bytes, which is the smallest logical storage unit in the file. Before and after the system of the terminal device, the identifier of the upgrade object does not change, but the data in the upgrade object may change. Wherein, if the upgrade object is a file, the identifier of the upgrade object refers to the identifier of the file. For example, when the upgrade object is a file, the identifier of the upgrade object is the file identifier abc of the file. After the upgrade, the file with the file identifier abc exists in the target version of the system, but the data in the file identified as abc has changed. . If the upgrade object is a block, the identifier of the upgrade object refers to the identifier of the block. For example, when the upgrade object is block, the identifier of the upgrade object is the file identifier block X of the block. After the upgrade, the target version of the system also has a block whose block identifier is block X, but the data in the block identified as block X has already been A change has occurred.

Step 203: The server sends the repair data of the upgrade object to the terminal device, where the repair data may be the original data of the upgrade object in the original version of the system.

Step 204: The terminal device repairs the system of the terminal device by using the repair data, and obtains the repaired system.

The repair data is the original data of the upgrade object in the original version of the system. When the upgrade object is a file, the repair data is the original data of the file determined to be the upgrade object in the original version of the system; when the upgrade object is a block, the repair data is The raw data of the block determined to be the upgrade object in the original version of the system.

After determining the upgrade object in step 202, the server determines the original data of the upgrade object in the original version of the system. For example, the storage address of the original data may be determined according to the identifier of the upgrade object, and then a storage area is determined according to the storage address. The original data of the upgrade object in the original version of the system is obtained from the storage area, and the original data of the upgrade object in the original version of the system is recorded as the repair data of the upgrade object. The repair data of the upgrade object, including the storage address of the upgrade object, and the like, and the original data of the upgrade object in the original version of the system. The server sends the repair data of the upgrade object to the terminal device, and the terminal device determines the object to be repaired according to the repair data of the upgrade object received.

When the upgrade object is a file, in the repair data of the file, the identifier of the file may be a file name or the like, and the repair data is the original data of the file in the original version of the system. The terminal device determines the file to be repaired according to the received file name or the cultural storage address, and uses the repair data of the file to overwrite the data of the file in the terminal device to complete the repair.

When the upgrade object is a block, in the repair data of the block, the block identifier includes the block offset address, the storage address of the file to which the block belongs, the total length of the block data, the start block number, and the end block number, and the repair data is the block in the original. The raw data in the version of the system. The terminal device determines the block to be repaired according to the received block offset address, the storage address of the file to which the block belongs, the total length of the block data, the starting block number, and the ending block number, and the repair data of the block is used to overwrite the terminal device. Block the data and complete the repair. It should be noted that when the upgrade object is a block, in addition to the block start number, according to any one of the block data total length and the end block number, the block to be repaired may be determined, and the block identifier may include only the block. The total length of the data and the end block number may also include the total length of the block data and the end block number, which are not limited in this application.

It should be noted here that when the upgrade object is a block, the upgrade object includes multiple blocks, and multiple blocks are contiguous in the file. The starting block number refers to the number of the block arranged in the top position in the file, and the ending block number refers to the number of the block arranged in the last position in the file.

For example, a terminal device receives the repair data of the upgrade object sent by the server, where the upgrade object is a block, and the identifier of the block is: the storage address of the file to which the block belongs: 1000, the block offset address: 120, the total length of the block data: 555, starting block number: 1364, ending block number: 1368. First, the terminal device finds the file to which the block belongs according to the storage address 1000 of the file to which the block belongs; then, according to the block offset address 120, determines the starting block, that is, the block corresponding to the starting block number; and then, from the starting block number 1364 To the end block number 1368, five consecutive blocks are upgraded objects, and the total length of the data in these five blocks is 555. The repair data of the above five blocks in the terminal device is replaced by the repair data of the received five blocks, and the repair of the above five blocks is completed.

For an end device, the system used before the repair and the system used after the repair are the original versions, but the data of the system actually used before the repair of the terminal device may exist with the data of the system originally used by the original version. Data differences. The data of the system actually used before the repair of the terminal device is defined as the current data, and the data of the system originally used by the original version is the original data.

During the repair process, if there is an upgrade object in the current data of the system of the terminal device, the repair data of the upgrade object is used to overwrite the current data corresponding to the upgrade object in the current data. For example, if the current data of the system actually used before the repair of a terminal device includes the upgrade object A, and the current data in the upgrade object A is xxy, the repair data of the upgrade object A is used, that is, the original data of the upgrade object A in the system is xy. After the current data xxy is overwritten, the current data in the upgrade object A in the system of the terminal device is consistent with the original data, and both are xy.

If the upgrade object does not exist in the current data of the system of the terminal device, the repair data of the upgrade object is added. For example, if the current data of the system actually used before the repair of a terminal device does not include the upgrade object A, that is, the current data in the upgrade object A is empty, the repair data of the upgrade object A is upgraded, that is, the upgrade object A corresponds to the used object. The original data xy of the system is added to the current data where the upgrade object A should be located. After the addition, the current data in the upgrade object A in the system of the terminal device is consistent with the original data, both of which are xy.

The repaired system is consistent with the original version of the system and is the basis for differential upgrade of the terminal device system. The original data in the system of the original version of the terminal device refers to the unmodified data corresponding to the upgrade object when the original version was originally released, and the terminal device can adopt the differential upgrade mode based on the original data of the original version. , upgrade from the original version to the target version. Any change in the original data of the upgrade object of the original version of the terminal device will cause the differential upgrade package to be unusable and cannot be upgraded by differential upgrade. Therefore, in the embodiment of the present application, before the differential upgrade is performed, the repair data of the upgrade object to be upgraded is acquired, and the system of the original version of the terminal device is repaired to ensure the data of the upgrade object in the terminal device, and the original version. The raw data of the system is consistent, ensuring the effectiveness of differential upgrades.

For example, for the original version of the system, there are objects: file 123, file 123 contains data a, b1, and file 123 exists in the target version of the system, including data a', b', and the upgrade object is file 123. In the original version of the system, it can be known that the original data of the file 123 is a, b, and the repair data is the original data a, b corresponding to the file 123; the terminal device uses the original data a, b in the file 123 to overwrite the current in the file 123. The data a and b1 are repaired, and the current data in the upgrade object file 123 after the repair is consistent with the original data, and the data is a and b, that is, the repaired system is consistent with the original version system.

For example, for the original version of the system, there is an object: block 1000, block 1000 contains data a1, b, c, and in the target version of the system, block 1000 also contains data a', b', c', and the upgrade object is block 1000. In the original version of the system, it can be known that the original data of the block 1000 is a, b, and c, and the repair data is the original data a, b, and c corresponding to the block 1000; the terminal device uses the original data a, b, and c in the block 1000 to cover the block 1000. The current data a1, b, and c complete the repair of the block 1000, and the current data in the upgraded object block 1000 after the repair is consistent with the original data, all of which are a, b, and c, that is, the repaired system is consistent with the original version system.

It should be noted that the current data and the original data are the current data and the original data corresponding to the upgrade object. When the repair is performed, only the upgrade object is used, and the current data of the upgrade object is repaired by using the repair data of the upgrade object, so that The current data corresponding to the upgrade object is consistent with the original data corresponding to the upgrade object. As for the other non-upgrade object parts of the system, whether the repaired data is consistent with the data of the original version, the application is not concerned.

Step 205: The terminal device uses the differential upgrade package sent by the server to upgrade the system from the original version to the target version. Through the step 204, the terminal device obtains the repaired system, and ensures that the current data in the terminal device is consistent with the original data of the original version of the system, and meets the preconditions of the differential upgrade.

The terminal device receives the differential upgrade package sent by the server, and uses the differential upgrade package to perform differential upgrade on the upgrade object. The differential upgrade can be a file-based differential upgrade, the file differential upgrade is a file-based upgrade, or a block-based differential upgrade, and the block differential upgrade is an upgrade based on blocks in the file.

It can be seen from the above technical solution that the method for differential upgrade provided by the embodiment of the present application includes repair data and a differential upgrade package. When upgrading, first use the repair data to repair the system of the terminal device, and ensure that the current data corresponding to the upgrade object in the terminal device is consistent with the original data in the original version of the system; on this basis, the differential upgrade package is used. After the upgrade is completed, the system of the terminal device is upgraded from the original version to the target version.

In the differential upgrade method provided by the embodiment of the present application, in order to avoid the differential upgrade failure caused by the original data of the original version used by the terminal device being modified, before the terminal device adopts the differential upgrade, the original version of the system is acquired, and the target version is The upgraded object of the system is different, and the system of the terminal device is repaired by using the repair data of the upgrade object, and the system is repaired to be consistent with the original version of the system, and then the repaired system is differentially upgraded. Repairing first and then differentially upgrading ensures the effectiveness of the differential upgrade mode for the terminal device.

In the foregoing embodiment of the present application, before the terminal device performs the differential upgrade, the system of the terminal device needs to be repaired. In the above example, in order to better understand the advantages of the technical solution of the present application, the example is the repair data of the default upgrade object, which is inconsistent with the current data of the upgrade object in the system actually used by the terminal device. In the actual application scenario of the implementation provided above, whether the repair data of the upgrade object is consistent with the current data of the upgrade object in the system actually used by the terminal device, the repair data of all the upgrade objects is obtained from the server, and the repair data is used. The current data of the upgrade object is repaired, and then the differential upgrade package is used for differential upgrade, which ensures the effectiveness of the upgrade using the differential upgrade method.

However, when the differential upgrade is actually performed, the repair data of the upgraded object may be completely consistent with the current data of the upgraded object in the system actually used by the terminal device, and thus the system of the terminal device is not required to be repaired. The differential upgrade package is used for differential upgrade. The repair data of the upgrade object may be inconsistent with the current data of the upgrade object in the system actually used by the terminal device, instead of all being inconsistent, only the current data is inconsistent with the original data. The upgrade object is fixed and then differentially upgraded using a differential upgrade package. Therefore, in order to further reduce the amount of data and the number of repairs of the repair data, a verification step may be added to determine whether the upgrade object needs to be repaired. For details, refer to the differential upgrade method provided in one embodiment of the present application.

As shown in FIG. 3, in an example, the method for differential upgrade provided by the embodiment of the present application includes:

Step 301: The terminal device acquires verification data of the upgrade object, where the verification data corresponds to the original data of the upgrade object.

The verification data corresponds to the original data of the upgrade object in the original version of the terminal device. In one case, the verification data of one upgrade object is the original data of the upgrade object itself; in another case, an upgrade The checksum data of the object is the hash value of the original data of the upgrade object. In a specific implementation, after the server learns the original version of the terminal device, the server compares the original version of the system with the target version of the system to obtain an upgrade object; the server obtains the original data corresponding to the upgrade object in the original version of the system; The original data is directly used as the verification data of the upgrade object, or a hash value is used to calculate the hash value of the original data, and the hash value is used as the verification data of the upgrade object.

It should be noted that the verification data is represented by the hash value of the original data, actually realizing the compression of the original data, reducing the data amount of the verification data, saving the storage space occupied by the verification data, thereby reducing the transmission. The time to verify the data. Step 302: The terminal device verifies, according to the verification data, the current data of the upgrade object in the terminal device, whether it is consistent with the original data. If not, step 303 is performed; if yes, step 305 is performed.

The current data refers to the current data corresponding to the upgrade object on the system actually used by the terminal device. In the case of eMMC data hopping or being hacked, the current data corresponding to the upgrade object in the terminal device may be inconsistent with the original data of the upgrade object. Therefore, the terminal device must first verify the upgrade object and verify the Whether the original data of the upgrade object has changed.

In an implementation manner, the verification data is the original data of the upgrade object. In this case, the original data of the upgrade object is compared with the current data of the upgrade object in the terminal device, and if the original data and the current data are completely consistent, It means that the original data of the upgrade object has not changed; if the original data is not completely consistent with the current data, it means that the original data of the upgrade object has been modified.

When the upgrade object is a file, the original data is the original data in the file corresponding to the original version of the terminal device; and the current data is the original version of the system actually used on the terminal device, the file corresponding to the file Current data in . The verification process is to compare whether the original data corresponding to each file is consistent with the current data. If the current data of a file is modified on the basis of the original data, the verification result of the file is inconsistent; The current data of the files is still the original data when the original version of the system was installed, and has not been modified. Then, the verification result of the file is consistent.

When the upgrade object is a block, the original data is the original version of the terminal device, and the original data in the block corresponding to the block; and the current data is the original version of the system actually used on the terminal device, the block corresponding to the block Current data in . The verification process is to compare whether the original data corresponding to each block is consistent with the current data. If the current data of a block is modified on the basis of the original data, the verification result of the block is inconsistent; The current data of the block is still the original data when the original version of the system is installed, and has not been modified. Then, the check result of the block is consistent.

In another implementation, when the verification data is a hash value of the original data, step 302 includes:

The terminal device obtains a hash value of the current data, and checks whether the hash value of the current data is consistent with the check data.

When the verification data is a hash value of the original data of the upgrade object, the terminal device acquires the current data of the upgrade object, and then uses the same hash algorithm to calculate the hash value of the current data, and the obtained upgrade. The hash value of the original data of the object is compared. If the hash value of the original data is completely consistent with the hash value of the current data, it indicates that the original data of the upgrade object is also consistent with the current data, that is, the original data of the upgrade object. No change occurs; if the check data is inconsistent with the hash value of the current data, it means that the original data of the upgrade object is not completely consistent with the current data, that is, the original data of the upgrade object has been modified.

When the upgrade object is a file, the verification data is the original version of the terminal device, and the file corresponds to the hash value of the original data calculated by the hash algorithm, and the current data corresponding to the file is obtained. After that, the hash value of the current data needs to be calculated according to the same hash algorithm. The process of verification is to compare whether the check data corresponding to each file and the hash value of the current data are consistent. If the current data of a file is modified on the basis of the original data, the check data in the file is The hash value of the current data is inconsistent, that is, the check result of the file is inconsistent; if the current data of a file is still the original data when the original version is installed, the hash of the check data and the current data in the file The values are the same, that is, the verification result of the file is consistent.

When the upgrade object is a block, the verification data is the original version of the terminal device, and the block corresponds to the hash value of the original data calculated by the hash algorithm, and the current data corresponding to the block is obtained. After that, the hash value of the current data needs to be calculated according to the same hash algorithm. The verification process is to compare whether the check data corresponding to each block and the hash value of the current data are consistent. If the current data of a block is modified on the basis of the original data, then the check data in the block is The hash value of the current data is inconsistent, that is, the check result of the block is inconsistent; if the current data of a block is still the original data when the original version is installed, the hash of the check data and the current data in the block The values are the same, that is, the check result of the block is consistent.

Step 303: The terminal device acquires the repair data of the upgrade object.

When the current data of the upgraded object is inconsistent with the original data of the upgraded object, the original data corresponding to the upgraded object is modified in the system of the original version actually used by the terminal device, and the terminal device needs to obtain the modified upgrade object corresponding to the upgraded object. Fix the data.

When the current data of an upgrade object is inconsistent with the original data, the upgrade object needs to be repaired to ensure that the current data of the upgrade object is consistent with the original data, and the differential upgrade can be used for the upgrade object. In this case, the server needs to obtain the upgrade target. Upgrade the repair data of the object. When the current data of an upgrade object is consistent with the original data, the upgrade object does not need to be repaired, and the upgrade object can be directly upgraded. Therefore, when the terminal device obtains the repair data of the upgrade object from the server, it only needs to obtain the repair data of the upgrade object whose current data is inconsistent with the original data, and does not need to acquire the repair data of the upgrade object whose current data is consistent with the original data.

If only the current data of the upgrade object is inconsistent with the original data, it is not necessary to obtain the repair data of all the upgrade objects, and only the repair data of the partial upgrade object is acquired. In this implementation scenario, the embodiment shown in FIG. Than, reduce the number of repair data for getting upgraded objects.

When the current data of the upgrade object is inconsistent with the original data of the upgrade object, the repair data of the upgrade object of the terminal device includes:

Step 303A: The terminal device sends the identifier information of the upgrade object to the server.

Step 303B: The server returns the repair data of the upgrade object to the terminal device according to the identifier information.

The identification information of the upgrade object refers to the information that can identify the upgrade object. When the upgrade object is a file, the identifier of the upgrade object is the identifier of the file, such as the file name. When the upgrade object is a block, the identifier of the upgrade object is the identifier of the block, such as the block offset address and the block. The storage address of the file, the total length of the block data, the starting block number, and the ending block number.

For the case of the upgrade object whose current data is inconsistent with the original data, the terminal device sends the identifier information of the upgrade object to the server; after receiving the identifier information of the upgrade object, the server obtains the original version from the server side through the identifier information. The original data corresponding to the identification information is returned to the terminal device as repair data.

For example, if the upgrade object is a file, when the current data corresponding to the file X is inconsistent with the original data, the name X of the file is the identifier of the file, and the terminal device sends X to the server, and the server finds the corresponding data in the original version according to the identifier X. The file whose name is X is returned to the terminal device as the repair data. If the upgrade object is block, when the current data corresponding to block N is inconsistent with the original data, the block number N is the block. The identifier is sent by the terminal device to the server, and the server finds a block named N in the original version of the system according to the identifier N, and returns the data in the block N as the repair data to the terminal device.

Step 304: The terminal device repairs the system of the terminal device by using the above repair data, and obtains the repaired system. The repair of the system in which the terminal device is actually used in step 304 is consistent with the description of step 204 in the embodiment shown in FIG. 2 of the present application, and details are not described herein again.

Step 305: The terminal device uses the differential upgrade package sent by the server to upgrade the system from the original version to the target version.

The difference between the terminal device and the terminal device in step 305 is the same as that in step 205 in the embodiment shown in FIG. 2, and details are not described herein again.

For example, when the upgrade object is a block, for the original version of the terminal device, there are upgrade objects: block1000, block1001, block1002, and block1003, where block1000 includes data A1 and B, and block1001 includes data C, D, block1002. Data E1 and F1 are included, and block 1003 contains data G and H. The check data obtained by the terminal device is the original data with the block identifier, specifically: the check data of block 1000 is A, B, the check data of block 1001 is C, D, and the check data of block 1002 is E, F, block 1003 check data is G, H; the terminal device compares the current data of each upgrade object with the original data according to the above check data, specifically: the current data of block 1000 is A1, B, block 1001 The current data is C, D, the current data of block 1002 is E1, F1, the current data of block 1003 is G, H, and the identifier of the upgrade object whose current data is inconsistent with the original data is block 1000, block 1002; terminal device block1000 The identification information of the block 1002 is sent to the server, and the server returns the original data A and B of the block 1000 corresponding to the identification information and the original data E and F of the block 1002 as the repair data to the terminal device according to the identification information of the block; the terminal device Using the received repair data, the current data of block 1000 and block 1002 are repaired in the system of the terminal device, and the repaired system is obtained. The upgrade object is upgraded by using the differential upgrade package sent by the server. In the upgraded target version, the corresponding upgrade object data is: A', B', C', D', E', F', G' , H'.

It can be seen that since the data in the two upgrade objects block1001 and block1003 are not modified, it is still the original data. Therefore, after the verification operation, the process of repairing block1001 and block1003 will not be performed, and the differential upgrade package is directly used for the difference. Upgrade can be performed; only for the upgrade objects with inconsistent verification such as block1000 and block1002, perform targeted repair and differential upgrade.

When the upgrade object is a file, in the system of the original version of a terminal device, there are upgrade objects: file 123, file 234, file 345, wherein file 123 contains data A, B, and file 234 contains data C, D, file. 345 contains data E, F. The verification data obtained by the terminal device is the original data with the file name, specifically: the verification data of the file 123 is A, B, the verification data of the file 234 is C, D, and the verification data of the file 345 is E, The terminal device compares the current data of each upgrade object with the original data according to the verification data, specifically: the current data A, B and the original data A, B of the file 123, the current data C, D of the file 234 and The original data C, D, the current data E, F of the file 345 and the original data E, F, the current data and the original data are all consistent; at this time, the terminal device will directly use the differential upgrade package sent by the server to perform the above upgrade object. In the upgraded target version, the corresponding upgrade target data is: A', B', C', D', E', F'.

It can be seen that the current data in the three upgrade objects of file 123, file 234, and file 345 has not changed with respect to the original data. Therefore, after the verification operation, it is not necessary to repair any upgrade object, and directly use the server to send The differential upgrade package can be differentially upgraded.

It should be noted that, in the above example, the verification data of the upgrade object is described by taking the original data of the upgrade object as an example, and the verification data of the upgrade object is the implementation manner of the hash value of the original data of the upgrade object. Similar, no more details here.

In the foregoing embodiment of the present application, in order to avoid the upgrade failure caused by the change of the version data of the terminal device, before the terminal device adopts the differential upgrade, the upgrade object is acquired, and the current data and the original data corresponding to the upgrade object are verified. The original data of the upgraded object that is inconsistent is verified as the repair data, and the original version of the system actually used by the terminal device is repaired. Through the above verification, the amount of repaired data and the number of repairs are reduced, the data volume of the differential upgrade process is further reduced, and the efficiency and effectiveness of the differential upgrade are specifically improved.

Referring to FIG. 4, in an application scenario, a method for differential upgrade provided by an embodiment of the present application includes:

In step 401, the server 100 generates verification data of the upgrade object according to the original data corresponding to the upgrade object.

Step 402: Send the verification data of the upgrade object to the terminal device 110.

In a specific implementation, the server 100 requests the terminal device 110 for the version number of the system currently used by the terminal device 110. The server 100 obtains the original data of the original version of the system corresponding to the version number according to the version number of the terminal device 110, and the server obtains the target data of the target version of the system, compares the original data with the target data, and obtains the original version. In the system, an object with data difference from the target version of the system is used as an upgrade target.

After determining the upgrade object, the server 100 obtains the original data corresponding to the upgrade object in the original version of the system, performs hash operation on the original data of each upgrade object, and obtains a hash value corresponding to the upgrade object, as the upgrade target school. Test the data. The verification data of the obtained upgrade target is transmitted to the terminal device 110.

Step 403: The terminal device 110 determines the upgrade object to be repaired according to the verification data of the upgrade object.

The terminal device 110 obtains the current data corresponding to the upgrade object in the system actually used by the terminal device 110, calculates a hash value of the current data, and verifies whether the check data corresponding to the same upgrade object is consistent with the hash value of the current data, if not consistent. , the upgrade object is used as the upgrade object to be repaired.

Step 404, the terminal device 110 sends the upgrade object to be repaired to the server 100.

The upgrade object to be repaired here refers to an upgrade object whose current data is inconsistent with the original data, and may be a file that changes in the terminal device 110 or a block that changes in the terminal device 110.

Step 405: The server 100 sends the repair upgrade package and the differential upgrade package to the terminal device 110, where the repair upgrade package includes original data corresponding to the upgrade object to be repaired in the original version of the system; the differential upgrade package includes required for differential upgrade. Target data corresponding to all upgrade objects.

The main technical idea of the differential upgrade technology is to compare the data difference between the system version on the terminal device and the system target version on the server, and to upgrade the data difference in units of files or blocks. Therefore, the differential upgrade package is similar to the structure of the fix pack. It does not involve the same data portion in two different versions of the system, and the volume of the package can be upgraded to a minimum.

The prerequisite for the differential upgrade is that the actual used system is consistent with the data of the corresponding upgrade object in the original system. Therefore, it is necessary to repair the actual used system first, and repair the current data of the upgrade object to be consistent with the original data of the upgrade object.

The repair upgrade package includes repair data, and the repair data is the original data of the upgrade object corresponding to the identifier information.

For example, for the upgrade object to be block, there is data in the original version of the server 100:

Imgdiff 2988 193 532207507257845300946f991021812b9df8cf68

3b898296759f6d169c18ca868e7e1f8324f58eb1 2,411364,411366 2 2,411364,411366

The bolded data is the starting block number and the ending block number. According to the starting block number and the ending block number, the original data corresponding to the upgrade object is extracted from the original version system, and a corresponding repair upgrade package is generated, specifically: Recover("/dev/block/bootdevice/by-name/system","3181","555","411364","411366"), the first parameter represents the block offset address that needs to be repaired, the second The parameter represents the storage address of the file to which the block belongs, the third parameter represents the total length of the block data, and the last two parameters represent the starting block number and the ending block number corresponding to the repair data; indicating that the repair data is from the block number 411364 to the block number. For 411366 a total of three blocks of data.

Regardless of whether it is a differential upgrade package or a repair upgrade package, the structure of the present application is not specifically limited in any embodiment of the present application. Any form of upgrade package structure can be used to clearly and simply guide the terminal device to complete the upgrade and repair of the specified upgrade object. It is within the scope of the embodiments of the present application.

For the differential upgrade package, the data packaged by the upgrade object in the target version of the system is packaged into data packets. Compared with the upgrade object, the data content of the object in the differential upgrade package reflects the upgrade type of the upgrade object. The upgrade type can be: replace, add, delete, and so on.

In another example, step 405 may only be performed and steps 401-404 may not be performed. When only step 405 is performed, the repair upgrade package includes the original data corresponding to all upgrade objects in the original version of the system. The upgrade object is repaired regardless of whether the current data corresponding to the upgrade object differs from the original data.

In step 406, the terminal device 110 performs repair of the data by using the repair upgrade package.

For details of the process of the repair, refer to the description of the embodiment described in FIG. 2, and details are not described herein again.

In step 407, the terminal device 110 performs the differential upgrade by using the differential upgrade package.

For an object in a differential upgrade package, if the upgrade type of the object is replacement, the upgrade process is: replacing the object in the original version of the terminal device with the object in the differential upgrade package. For example, for a certain terminal device, the original version of the system and the target version of the system have objects: block1000, block1001, block1002, block1003, wherein block1000 contains data A, B, block 1001 contains data C, D, block 1002 contains Data E, F, and block 1003 contain data G and H. The difference upgrade package includes the object block 1000, block 1001, block 1002, and block 1003, and the data in the above object is: block 1000 data is A', B', block 1001 data is C', D', block 1002 data is E', F ', the data of block1003 is G', H'. The differential upgrade package is used for differential upgrade. The specific differential upgrade process is: for the object block1000, replace the original data A and B with the data in the differential upgrade package for A' and B'; for the object block1001, use the data in the differential upgrade package. Replace the original data C, D for C', D'; for the object block1002, replace the original data E, F with the data in the differential upgrade package for E', F'; for the object block1003, use the data in the differential upgrade package for G ', H' replaces the original data G, H. After the differential upgrade, the corresponding data in the target version of the system is: A', B', C', D', E', F', G', H', and the differential upgrade is completed.

For an object in a differential upgrade package, if the upgrade type of the object is increased, the upgrade process is: adding the object corresponding to the differential upgrade package to the corresponding location in the system of the original version of the terminal device. It should be noted that the added object only exists in the system with the target version, and does not exist in the original version of the system. For example, for a system of the original version of a terminal device, block 1000, block 1001, and block 1002 are present, wherein block 1000 includes data A and B, block 1001 includes data C and D, block 1002 includes data E and F, and differential upgrade package includes upgrade. The type is the added object: block1003, and the added position is: adjacent to block 1002 and after block 1002, the data in block 1003 is: G', H'. The differential upgrade is performed by using the differential upgrade package. The specific differential upgrade process is: for the target block 1003, the data in the differential upgrade package is G', H' is added to the data E and F of the block 1002. After the differential upgrade, the corresponding data in the target version of the system is: A, B, C, D, E, F, G', H', and the differential upgrade is completed.

For an object in a differential upgrade package, if the upgrade type of the object is deleted, the upgrade process is: deleting the corresponding object in the original version of the terminal device by using the delete instruction of the object in the differential upgrade package. For example, for the original version of a terminal device, there are: block1000, block1001, block1002, block1003, where block1000 contains data A, B, block 1001 contains data C, D, block 1002 contains data E, F, block 1003 contains data G, H. The differential upgrade package contains the object block1000 and a "delete" instruction. The differential upgrade is performed by using the differential upgrade package. The specific differential upgrade process is: for the object block 1000, the original data A and B are deleted according to the "delete" command corresponding to the block 1000 in the differential upgrade package. After the differential upgrade, the corresponding data in the target version of the system is: C, D, E, F, G, and H, and the differential upgrade is completed.

In a specific implementation, the type of differential upgrade corresponding to all objects included in a differential upgrade package may be only one of adding, deleting, and replacing, or there may be any two or three of adding, deleting, and replacing. It is not limited here. In the process of performing the differential upgrade, each object in the differential upgrade package may be upgraded according to the upgrade type corresponding to the object.

According to the method of the embodiment of the present application, before the differential upgrade, the system actually used by the terminal device is verified, and the upgrade object whose verification result is inconsistent is repaired, and then the repaired system is differentially upgraded; The upgrade target with the same result is directly upgraded. On the one hand, the effectiveness of using the differential upgrade method for system upgrade is improved. On the other hand, the amount of repaired data and the number of repairs are further reduced, so that the repair of the upgrade object is more targeted, and the differential upgrade process is generally reduced. The amount of data.

For most of the differential upgrade packages, the volume is less than 10% of the full upgrade package of the same version. Even if the corresponding repair data is added, the volume of the upgrade package is much smaller than the volume of the full upgrade package. Therefore, the difference of the embodiment of the present application is The upgrade method can reduce the amount of downloaded data of the terminal device, shorten the download time of the upgrade package, and improve the efficiency and effectiveness of the differential upgrade to improve the user experience.

The embodiment of the present application further provides a differential upgrade device, which will be described in detail below with reference to the accompanying drawings.
