Description

Not sure if this is a bug or not. Steps to reproduce:

First, sync the repo https://fixtures.pulpproject.org/rpm-with-sha-1-modular/ on-demand.

Then if I publish this repo and its checksums appear to be sha256:

$ http :/pulp/api/v3/publications/rpm/rpm/19f661c0-f80f-45c7-8cce-4d50a84694fe/
HTTP/1.1 200 OK
Allow: GET, DELETE, HEAD, OPTIONS
Connection: keep-alive
Content-Length: 392
Content-Type: application/json
Date: Thu, 23 Jul 2020 20:59:36 GMT
Server: nginx/1.16.1
Vary: Accept, Cookie
X-Frame-Options: SAMEORIGIN

{
    "metadata_checksum_type": "sha256",
    "package_checksum_type": "sha256",
    "pulp_created": "2020-07-23T20:59:24.579748Z",
    "pulp_href": "/pulp/api/v3/publications/rpm/rpm/19f661c0-f80f-45c7-8cce-4d50a84694fe/",
    "repository": "/pulp/api/v3/repositories/rpm/rpm/6e1eebc1-1e9c-4874-b2cb-48a4fb73a091/",
    "repository_version": "/pulp/api/v3/repositories/rpm/rpm/6e1eebc1-1e9c-4874-b2cb-48a4fb73a091/versions/1/"
}

Then if I check the published primary.xml, the checksums are actually sha1.

The default value for metadata_checksum_type and package_checksum_type if not specified is sha256, so if you have not explicitly specified what checksum type it should be, repodata should have sha256. Same would have been with packages if you would not have downloaded with on_demand policy. Because only sha1 is available on the remote repo and you have downloaded with on_demand we have no way how to create sha256. If you would have downloaded with immediate, you would have sha256 in the primary.xml

This is not a bug but maybe we could use some docs that would explain these nuances.

Also, I noticed that even if I explicitly create the publication with sha256:

http :/pulp/api/v3/publications/rpm/rpm/ repository_version=/pulp/api/v3/repositories/rpm/rpm/615d4d10-cd16-40d2-ab75-dd042e77d27e/versions/1/ metadata_checksum_type=sha256 package_checksum_type=sha256

The primary.xml still ends up being sha1. I would expect an error but if we decide to document this issue, we should document this too.
