Preferred embodiment of the invention

The following is an overview of the topics detailed in this document. This Summary is not intended to limit the scope of the claims.

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment of the invention provides a differential fallback upgrade method.

Referring to FIG. 1 , it is a flowchart of a first embodiment of a differential fallback upgrade method according to the present invention.

In the first embodiment, the differential fallback upgrade method includes:

Step S10: Obtain an upgrade package and rollback information corresponding to the upgrade package.

Compare and analyze the data of the old version application with the data of the new version application by using the upgrade package creation tool on the server to detect whether there is any difference. When the version difference is not detected, continue to obtain a comparison analysis between the new version application and the old version application; When the difference is detected, the upgrade package file is generated according to the comparison result. At the same time, according to the comparison result, the rollback information is generated, and the rollback information can be packaged into the upgrade package when the upgrade package is generated by using the upgrade package creation tool. The fallback information can also be saved separately and associated with the upgrade package, for example, it can be named with the same version number, or a method such as adding an identifier to the rollback information.

It should be noted that the upgrade package here may be a complete upgrade package, a differential upgrade package, or both upgrade packages, so that the user can enter the upgrade as needed. Line selection; Moreover, the upgrade here may be an upgrade of the operating system of the terminal, or an application software upgrade on the terminal, the principle is the same.

The full version of the data packet occupies a large memory and the upgrade speed is slow, and the differential upgrade package differentiates the new version file from the data of the old version application, and obtains the updated patch file. For example, the old version file has 5M, and the new version file has 8M. The updated part may only be about 3M (here, it should be noted that the differential packet size is not a simple subtraction, in fact, it needs to contain some context-related things), the benefits of using differential upgrade are obvious, users do not need to download the complete 8M The file only needs to download the update part, and the update part may only have 3-4M, which can greatly reduce the loss of traffic. Therefore, in this embodiment, it is preferable to generate a differential upgrade package for upgrading.

In this embodiment, the backoff information includes the path information of the old version data segment corresponding to the difference data applied by the new and old versions, for example, “xx/xx/filename”, because the difference file generally includes multiple, so back The content of the return information can be:

"rollback:

"xx/xx/filename1"

"xx/xx/filename2"

"xx/xx/filename3"

......"

In other embodiments, the rollback information may be defined in other manners. For example, the rollback information may include the identifier information of the old version file corresponding to the difference file of the new and old version files, so as to extract corresponding data segments according to the flag information. .

Step S20: Generate a differential backoff packet according to the obtained backoff information.

As shown in FIG. 2, step S20 includes the following refinement steps:

Step S201 analyzes the obtained back-off information, and acquires path information according to the back-off information.

Step S202, generating the differential backoff packet according to the path information. As shown in FIG. 3, step S202 includes the following refinement steps:

Step S211: Extract an application data segment corresponding to the path information in the application data corresponding to the to-be-upgraded application.

Step S212, the obtained application data segment is encapsulated and digitally signed to generate the differential backoff packet.

The information about the corresponding application data segment is included in the rollback information, and the corresponding application data segment is obtained from the terminal system file in the order of multiple fallback subcommands, and the obtained information is obtained after the rollback information line is executed. All the application data segments are encapsulated. After the encapsulation is completed, it can be compressed into a zip file or compressed in another compression format. According to the signature key sent by the server or the signature key preset by the terminal, the number is returned for the rollback packet. Signature, digital signature is a common technical means, and will not be repeated here.

In step S30, the upgrade application is upgraded according to the obtained upgrade package.

Step S40: Perform a rollback operation on the to-be-upgraded application according to the generated differential back-off package when the upgrade fails.

An upgrade failure may occur during the upgrade. In this case, the differential rollback package is automatically retrieved to roll back and the system is rolled back to the original state.

The differential back-off upgrade method proposed in this embodiment uses the data of the new and old versions to compare and obtain the upgrade package and the difference information. Before the upgrade, the differential back-off package is generated according to the difference information, and is digitally signed and saved. Roll back after the upgrade failed.

Referring to FIG. 4, a second embodiment of the differential rollback upgrade method of the present invention is proposed based on the first embodiment. In this embodiment, after the step S40, the method further includes:

Step S50, storing the differential backoff package.

In step S60, after the upgrade is successful, a rollback command is received.

Step S70, extracting the differential back-off package corresponding to the received back-off instruction.

Step S80: Perform a rollback operation on the upgraded application to be upgraded according to the extracted differential backoff package.

Save the differential fallback package to the terminal for the user to use. For example, after a successful upgrade, if there is a system error or an application error, the user does not want to use the current version. If you want to roll back the version, you can directly select the differential rollback package for version rollback. You do not need to download the complete rollback package from the server. , can achieve the purpose of rapid rollback. At this time, the user may be provided with a selection interface. The user sends a back-off instruction based on the selection interface. After receiving the back-off instruction issued by the user, the user sends the differential back-off package corresponding to the received back-off instruction, and the application is to be upgraded. Perform a version rollback.

In the differential rollback upgrade method in this embodiment, if the user does not want to use the upgraded version after the differential upgrade is completed, the previously generated differential backoff package can be called back to the version before the upgrade.

The embodiment of the invention further provides a differential back-off upgrade device.

"rollback:

"xx/xx/filename1"

"xx/xx/filename2"

"xx/xx/filename3"

......"
