you forgot to select the base commit of the diff

I've deliberately created the diff with the 3 commits inside, I just forgot to update the title ;)

make sure we don't accidentally return an incorrect value

not related to this diff, but we really shouldn't use directory_ls. It's slow because it joins against other tables, but swh-provenance doesn't use any of the values obtained by the join. swh.storage.algos.directory.directory_get should be used instead.

This revision is now accepted and ready to land.Wed, Jun 15, 12:30 PM

Thanks for the suggestion, we need to define what must be improved / developed in provenance, I add this in the list.

Update according the reviews

  • Add and fix license headers
  • Ensure the _revisions_count variable was computed before returning its value

This code does not use the swh.storage implementations, but direct SQL queries implemented in swh.provenance.postgresql.archive.
