Task #8322
Updated by bmbouter over 3 years ago
In 3.10, the default for ALLOWED_CONTENT_CHECKSUMS included md5 and sha1. In 3.11, it does not.
## Problem
If the user hasn't manually brought back md5 and sha1 in the `ALLOWED_CONTENT_CHECKSUMS` setting, this will present a problem at upgrade time when the `pulpcore-manager migrate` goes to run. Specifically Pulp will refuse to run the `migrate` because Artifacts have md5 and sha1 from <3.11 and the user (and installer) never ran `pulpcore-migrate handle-artifact-checksums`.
## Experience the problem
1. Install a 3.10 version of pulp
2. Sync down https://fixtures.pulpproject.org/rpm-with-md5/
3. Upgrade to 3.11
## Solution
Have pulpcore ship a migration with 3.11 that runs the `pulpcore-migrate handle-artifact-checksums` command from the migration itself. Users can set the `ALLOWED_CONTENT_CHECKSUMS` to the checksums they desire prior to starting pulpcore 3.11 and if they do nothing this migration will ensure the don't encounter a problem.
Additionally this check here needs to not perform the check for the `migrate` command also: https://github.com/pulp/pulpcore/blob/master/pulpcore/app/settings.py#L312 Otherwise the migration itself won't be able to run to resolve the problem.
