Description Ina Panova 2021-04-27 11:03:31 UTC

Description of problem:

Pulp3 to pulp2 sync fails because of missing empty blob. In the converted manifest schema1 an empty blob with digest sha256:a3ed95caeb02ffe68cdd9fd84406680ae93d633cb16422d00e8a7c22955b46d4 is present and pulp2 tries to fetch it unsuccessfully because pulp3 does not have it on the fs

When I try to curl one of these, I get:

{"errors":[{"code":"BLOB_UNKNOWN","message":"Blob not found.","detail":{"digest":"sha256:a3ed95caeb02ffe68cdd9fd84406680ae93d633cb16422d00e8a7c22955b46d4"}}]}

Comment 8 Ina Panova 2021-05-07 15:38:19 UTC

Steps to verify:
1. create and sync in pulp3 "foreman/busybox-test" from quay.io
2. Confirm that in the repo there is only one manifest of schema2(introspect pulp3 repo)
3. Confirm that pulp3 does not contain blob with the following digest:
                                                                                                                                                                      
pulpcore-manager shell -c "from pulp_container.app.models import Blob; print(Blob.objects.filter(digest='sha256:a3ed95caeb02ffe68cdd9fd84406680ae93d633cb16422d00e8a7c22955b46d4'))"

This should give an empty result.

4. trigger capsule sync, it should succeed.
