Subject [jira] [Created] (LIBCLOUD-540) Implement Copy Object Semantic

------------------------------------

             Summary: Implement Copy Object Semantic
                 Key: LIBCLOUD-540
                 URL: https://issues.apache.org/jira/browse/LIBCLOUD-540
             Project: Libcloud
          Issue Type: Improvement
          Components: Storage
            Reporter: Kyle Kelley


Several providers have a copy object semantic that works within one datacenter/region. [Azure
copy Blob](http://msdn.microsoft.com/library/azure/dd894037.aspx), [OpenStack Swift object
copy](http://docs.openstack.org/api/openstack-object-storage/1.0/content/copy-object.html).

I have not dug into Amazon S3 or any others, so I could use some guidance there.

I'd like to design it to be used cross-providers instead of ex_copy_object, as discussed in
 https://issues.apache.org/jira/browse/LIBCLOUD-275?focusedCommentId=13959367&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13959367.

I'm imagining that the StorageDriver class would get this function header:

def copy_object(self, src_container_name, src_object_name, dst_container_name, dst_object_name)

That layout works for both OpenStack/Rackspace/HP and Azure, minus any additional metadata
headers that you might want to send for these providers. Is there a clean way to handle that?
