Migrate to using VirtualCodebase from the latest scancode

[steven-esser]

scancode-toolkit can re-create a Codebase object and its Resource (files, dirs) from a scancode json results file.

It will useful to convert DeltaCode to using this VirtualCodebase object as the means of doing all the delta operations. Their natural tree structure makes traversing a scan easier, and a variety of other delta operations become easier to do. We also wont have to maintain as many python Objects as we do now; most of these are replicated in a VirtualCodebase (License, Copyright, etc)

@MaJuRG , @johnmhoran I can not get this following line :

scancode-toolkit can re-create a Codebase object and its Resource (files, dirs) from a scancode json results file.

What I know is scancode can generate a json output upon scanning a particular codebase,
using this or similar related commands ::
./scancode -clip --json-pp - samples

So basically I want to know what does CodeBase object and Virtual codebase refers in this context.
Can you please clarify it ,as I would like to solve this issue done

Thanks @MaJuRG for the explanation 😃

@MaJuRG @arnav-mandal1234 Hello. I have 2 questions.

• Do I have to write a concrete plan on GSoC proposal? In other words, is a specific description (like, "This and this will be replaced by using VirtualCodebase. The returning values should be like this. Arguements are... etc.) needed?
• Or, are general understanging and strict scheduling important/enough?

Thanks.

@kvoj the more detailed, the better.
