DUpdateSystem
[bug/core] cache function auto test support
The basic use of the software or there are certain problems, check the application directly stuck, I do not know what optimization of this approach is not. https://user-images.githubusercontent.com/92291796/190955731-7a53a848-43fb-4fc4-96da-3d5ee0b16b1f.mp4
Software check update logic is strange, there is a relevant link address but does not show the updated version, check once and then to re-check the list, which can directly remember the last use of the source on the line, in addition to use other sources to re-check the single application is better than the whole list again, and the application is too dependent on the cloud, feel good confusion, the use of experience really needs to be strengthened, that is, the application is experienced after the issue of the package not, these application experience should be able to experience, cheer up, I hope the application can be better used in the future
I remember the software was developed with these in mind, but don't know why it failed, it also needs some automated testing.
