Doc Text:
Previously, incorrect header-processing logic in the Ceph Object Gateways S3 interface caused multi-part copy-part requests lacking the "x-amz-copy-source-range" header to be processed as whole-object copy requests. This caused, requests of this type to fail with the "404, NotFound" error when performed with AWSv4 request signing. With this update, the header processing logic has been corrected and S3 multi-part copy-part requests can be executed as expected by S3 clients.

Description Matt Benjamin (redhat) 2018-08-09 23:17:44 UTC 
Description of problem:

When use copy part without http header "x-amz-copy-source-range"，rgw will use copy_obj to handle it. But according to aws s3 doc https://docs.aws.amazon.com/AmazonS3/latest/API/mpUploadUploadPartCopy.html:

    "This request header is not required when copying an entire source object."

So, "x-amz-copy-source-range" is a optional header, and it can't be a mark to distinguish "copy part" from "copy object".

The issue can be reproduced with Jewel 10.2.10.
