This MR adds the ability to share files between packages and version in the debexpo repository.
The following features has been implemented:
- Replacing the unique constraint on the path to a unique constraint on the tuple (package, version and path)
- Files can be shared between RepositoryFile:
- Check on file removal for in-use RepositoryFile
- Check on file installation for already created RepositoryFile
- Previous version of a file is removed only if the checksum mismatch
This altogether allow the following to happen:
A upload with 1.0-1 and 1.0-2 sharing the same orig can live inside the repository (regardless of their distribution targeted).
Tests have been update to match the new behavior.
Closes #138 (closed).
