Move the user id from project name to a label #387

[tdruez]

• Issue: BUG: Unnecessary duplicate scans with "Scan All Packages" due to inclusion of user UUID in ScanCode.io project name #387

Changes:

• Move the {user_hash} from the project name to a project label
• Check if a Scan is already available before submitting a scan request to ScanCode.io (instead of handling the error post-submit)

The submitting project name evolves:

• from {uri_hash}.{dataspace_hash}.{user_hash}
• to {uri_hash}.{dataspace_hash} + {user_hash} added as a label on the project.

Data migration

The following script can be applied to the ScanCode.io instance side if you wish to support the "Created by me" filter feature on the "Scan list" for old scans:

$ ./manage.py shell

from scanpipe.models import Project
from django.db.utils import IntegrityError

projects = (
    Project.objects.filter(
        runs__pipeline_name__in=["scan_single_package"],
        name__regex=r"^[a-f0-9]{10}\.[a-f0-9]{10}\.[a-f0-9]{10}$",
    )
)

for project in projects:
    parts = project.name.split('.')
    # Join all parts except the last one as the new name
    new_name = '.'.join(parts[:-1])
    try:
        project.update(name=new_name)
    except IntegrityError:
        continue
    # Get the last part as label
    label_value = parts[-1]
    project.labels.add(label_value)
