ScanCode.io: Design and implement discrepancies reporting

[pombredanne]

We need to create data models in ScanCode.io to track d2d discrepancies and incorporate these into the binary to source pipelines. This could be flexible and be part of a general discrepancy reporting and does not have to be dedicated only to d2d.

@pombredanne please give me design on this when you get chance.

This is done. We now have:

• an endpoint on matchcodeio /api/d2d to run d2d and report discrepancies

This PR has been merged:

• https://github.com/nexB/purldb/pull/433

To test this feature:

• Install PurlDB and matchcode.io from the main branch

• Run

  • make dev
  • make run_matchcodeio

• Make a request to /api/d2d endpoint using two Input URLs

For example these:

• https://github.com/nexB/scancode.io/raw/main/scanpipe/tests/data/d2d-go/from-data.zip#from
• https://github.com/nexB/scancode.io/raw/main/scanpipe/tests/data/d2d-go/to-data.zip#to

Then click POST button and do refresh.

The codebase_resources_discrepancies field indicates the number of resources that have discrepancies.
