I would like to give example of php client object copy method :
Assumption :
bucket-name : test
file exist on bucket : README

$result = $client->copyObject(array( "Bucket" => "test", "CopySource" => "/test/README", "Key" => "README.copy",));

Request Header object :

Host: test.localhost:8081
User-Agent: aws-sdk-php2/2.5.3 Guzzle/3.8.1 curl/7.19.7 PHP/5.3.3
x-amz-copy-source: /test/README
Date: Tue, 04 Mar 2014 08:08:21 +0000
Authorization: AWS 05236:q747YzZHx8zJd7+jDKXXzPsCxV0=
Content-Length: 0

i tried with all possible option for CopySource parameter :
e.g.
"CopySource" : "/test/README"
"CopySource" : "test/README"
"CopySource" : "README"
but new copied file size is 0 byte.
NO Error log in gateway, storage or on terminal no exception or warning seems.

Thank you for your report. We'll check this issue soon.

Since LeoFS have expected to exist a x-amz-metadata-directive header(but aws spec is allowed no existing this header), if this header didn't exist, LeoFS handled the http request as a normal PUT with no http body.
So we will fix ASAP.

Hi @Paras2009
This issue have been fixed on develop branch at leo_gateway repo.
So could you confirm if this issue is fixed?

    # build LeoFS with the fixed version 
    cd ${leofs_repo_root}
    make deps
    (cd deps/leo_commons;git checkout develop;)
    (cd deps/leo_object_storage;git checkout develop;)
    (cd deps/leo_gateway;git checkout develop;)
    make
    make release
