Checking method and device based on block mode incremental upgrade package and storage medium

Abstract

The invention discloses a verification method and device based on a block mode incremental upgrade package and a storage medium, and the method comprises the steps: traversing an operation descriptiontable of a full-amount upgrade package, sequentially analyzing a newly added block data command and a data emptying command, and restoring complete full-amount upgrade package data; traversing the operation description table of the incremental data packet, calculating check values of the incremental upgrading packet and the full upgrading packet, and judging whether the check values of the incremental upgrading packet and the full upgrading packet are equal or not; and after the operation description table of the incremental data packet is traversed, when the check values of the incremental upgrade packet and the full-amount upgrade packet are all equal, the check result is that the data in the incremental upgrade packet is consistent with the data in the full-amount upgrade packet. According to the method for verifying the incremental upgrade package based on the block mode, whether the data in the incremental upgrade package based on the block mode is consistent with the data in thefull-amount upgrade package or not can be detected, the upgrade package issued by compiling can be well managed, and the consistency of the incremental upgrade package and the full-amount upgrade package is confirmed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a verification method, device and storage medium for a block-based incremental upgrade package. Background technique [0002] The FOTA (Firmware Over-The-Air) of the Android system, the over-the-air software upgrade of mobile terminals, refers to the cloud upgrade technology for devices with networking functions: such as mobile phones, tablet computers, portable media players, mobile Internet devices, etc. Firmware upgrade service, users use the network to obtain intelligent terminal system upgrade packages in an on-demand and easy-to-expand manner, and perform cloud upgrades through FOTA to complete system repair and optimization) The upgrade can be divided into two methods: full upgrade and incremental upgrade; , the full upgrade is to refresh all the system content, and the incremental upgrade is to upgrade only the differences. The final content after the two m...

Problems solved by technology

[0003] During the upgrade and deployment process, both the full package and the incremental package need to be prepared. Due to the characteristics of small physical examination and fast speed, the incremental package is usually used for upgrading versions with a large number of terminals on the market and small system differences; The volume package version is highly dependent and cannot be fully applied to various versions on the market. It is also necessary to prepare a full volume package to upgrade the version that has not deployed the incremental package

[0004] When the version is released, it is necessary to output a full package and several incremental packages at the same time, and in order to ensure the consistency of the content of the upgrade package, there are strict regulations on the incremental package and the full package: they must be output at the same compilation time ;In actual use, due to repeated compilation and other issues, the content in the full package and the incremental package may be inconsistent. Such an upgrade package will have a very large impact when it enters the market, and may cause a large number of terminal equipment incremental upgrades to fail. ; Therefore, for the management of full packages and incremental packages, a tool is needed to verify the consistency of the content in the upgrade package

[0005] In the prior art, it is an incremental upgrade based on the file mode. The file-based upgrade method is to store the content that needs to be upgraded in the upgrade package in the form of a file. When upgrading, it is decompressed and copied to the device to be upgraded. However, with the Android version This file-based upgrade method has been gradually eliminated. As of Android 8.0, the file-based upgrade method is no longer supported, which means that the above-mentioned upgrade method is no longer applicable to the latest Android system.
