I'd like to delete the attached email, but it's not possible. Sorry. I did not see that the object version that I tried to retrieve had a content type of "application/x-deleted;swift_versions_deleted=1". That explains the behaviour. Bernd. On 5/31/2020 4:33 PM, Bernd Bausch wrote:

According to documentation of Swift's new object versioning middleware [1], a deleted object won't be visible but previous version content is still recoverable.

Documentation doesn't say how, though. After deleting /myobject/, I can see its versions:

$ openstack object delete testcontainer myobject $ curl http://192.168.1.200:8080/v1/$ACCOUNT/testcontainer?versions -H "x-auth-token: $T" | python -m json.tool | grep -e version_id -e name         "name": "myobject",         "version_id": "1590896642.07497"         "name": "myobject",         "version_id": "1590892906.83929"         "name": "myobject",         "version_id": "1590892899.36921"

But I can't GET old versions of /myobject/:

$ curl -i http://192.168.1.200:8080/v1/$ACCOUNT/testcontainer/myobject?version-id="1590896642.07497" -H "x-auth-token: $T" HTTP/1.1 404 Not Found

After creating another object with the same name /myobject/, old versions are accessible again. This is a solution, but dare I say not a very elegant one. *Can **a deleted, versioned object be recovered without creating a dummy object with the same name?*
