---

Simple content copy means that content units can be copied from one repository into another repository without considering content-type-specific invariants, such as making sure dependencies are satisfied.

The most straightforwards current design is to model this after one-shot upload. A new URL endpoint will be defined at /api/v3/rpm/copy/. POSTing to that endpoint with valid parameters will yield an asynchronous task, which will result in a new repository version in the target repository.

The user workflow should look like this:

http --form POST http://localhost:24817/pulp/api/v3/rpm/copy/ source_repository=${S_REPO_HREF} destination_repository=${D_REPO_HREF}

Both the repository parameters are required. When called, all content will be copied.

The additions to Django boilerplate will look something like this (see also: copy.py for an example of the function that does the work, and OneShotUploadSerializer in serializers.py)

urls.py

urlpatterns = [
    url(r'rpm/upload/$', OneShotUploadView.as_view()),
    url(r'rpm/copy/$', CopyView.as_view())
]
