Rotate roots per spec #143

hosseinsia · 2021-08-10T14:25:16Z

Update root following the TUF specification v1.0.19
https://theupdateframework.github.io/specification/v1.0.19/index.html#load-trusted-root

Logic:

Call the update root first in any client updates.
Start from the current root version (n), loop through next versions by trying to fetch (n+1).root.json file.
For any new root, verify the signatures.

Some drive by comments. I'm not very familiar with go-tuf, so take them with a grain of salt.

This PR is very hard to review because of the number of added files. Do we need them all? Perhaps separate them into a separate commit so that the core logic change is easier to review?

Personally, I'm not a fan of the very large comments which seem likely to become out-of-date. But that appears to be the style for the go-tuf implementation.

updated according to comments. PTAL.

Major changes:

The code is being changes such won't persist a bad root metadata (except for when it is expired).
Added a few more tests to check for the cases of non-root key change.
Refactored/simplified the client_test

@hosseinsia do we have tests for whether expirations are ignored and not ignored correctly?
