When uploading an invalid rpm such as a non utf8 RPM, users should get a friendly error message
When users upload an invalid RPM such as one that has non-utf8 characters in their headers, they should get a 4xx response and a user friendly error message. Currently they receive a 500.
Steps to reproduce.
http POST http://localhost:8000/pulp/api/v3/repositories/ name=foo export REPO_HREF=$(http :8000/pulp/api/v3/repositories/ | jq -r '.results | select(.name == "foo") | ._href') wget https://repos.fedorapeople.org/pulp/pulp/fixtures/rpm-with-non-utf-8/rpm-with-non-utf-8-1-1.fc25.noarch.rpm http --form POST http://localhost:8000/pulp/api/v3/artifacts/ file@./rpm-with-non-utf-8-1-1.fc25.noarch.rpm http POST http://localhost:8000/pulp/api/v3/content/rpm/packages/ relative_path=rpm-with-non-utf-8-1-1.fc25.noarch.rpm artifact="/pulp/api/v3/artifacts/1/" filename=rpm-with-non-utf8.rpm

The Pulp2 behavior for a RPM to Pulp2 with non utf-8 chars in certain fields would have those invalid chars removed. That's good for being able to sync repositories with invalidly formed RPMs. It's not good because Pulp is mutating the data in unexpected ways. For example now the checksum of that field won't validate correctly after passing through Pulp which is a problem. The real fix is for those RPMs to have their metadata correctly utf-8 encoded.
Note that per the spec in section 2.3.1, RPMs expect utf-8 encoding for various fields, so Pulp3 is correct in rejecting an encoding it can't interpret. Since we aren't getting active bug reports from users, I think we should close this for now. I'm leaving open to go back through triage.
Other ideas and thoughts/concerns are welcome.
