Resin’s delta server supports Balena deltas as version 3 deltas. This commit adds support for triggering delta generation for Balena deltas, and applying them locally to the device via a simple pull.
The delta version to use when updating has been abstracted away as an env var that is user-defined. The default value is still instructing use of rsync deltas (v2).
Change-Type: minor
We add a bunch of additional unit tests, and also a coverage report using istanbul.
The tests are not meant to cover everything, but they're a first attempt at having *some* unit testing
on the supervisor. There's much to improve but hopefully it helps catch obvious errors.
