can't S3 versioning through REST

[Dick Tang]

while I can access successfully
 by s3curl http://192.168.0.37:8773/services/Walrus/dick-personal-bucket?acl
I can't show versioning status by
s3curl http://192.168.0.37:8773/services/Walrus/dick-personal-bucket?versioning
and it returns:
javax.security.auth.login.LoginException: Login Failure: all modules ignored

I've taken a look on the
clc/modules/wsstack/src/main/java/com/eucalyptus/ws/handlers/WalrusAuthenticationHandler.java line ~182
for(WalrusProperties.SubResource subResource : WalrusProperties.SubResource.values()) {
                                                if(subResourceCandidate.equals(subResource.toString().toLowerCase())) {
and accroding to
clc/modules/core/src/main/java/com/eucalyptus/util/WalrusProperties.java
WalrusProperties.SubResource is defined as enum { acl, logging, torrent, location }

I tried to replace part of WalrusProperties.java with
        public enum SubResource {
                acl, logging, torrent, location, versioning, versions
        }

and everything seems ok now

suggested fix:
clc/modules/wsstack/src/main/java/com/eucalyptus/ws/handlers/WalrusAuthenticationHandler.java line 182

                        if(addrStrings.length > 1) {
                                addrString += "?";
                                String[] subResourcesCandidates = addrStrings[1].split("&");
                                for(String subResourceCandidate : subResourcesCandidates) {
                                        String subResourceCandidateHead = subResourceCandidate.split("=")[0];
                                        for(WalrusProperties.SubResource subResource : WalrusProperties.SubResource.values()) {
                                                if(subResourceCandidateHead.equals(subResource.toString())) {
                                                        if(!addrString.substring(addrString.length()-1).equals("?")) addrString += "&";
                                                        addrString += subResourceCandidate;
                                                }
                                        }
                                }
                        }

clc/modules/core/src/main/java/com/eucalyptus/util/WalrusProperties.java: line 245
        public enum SubResource {
                acl, logging, torrent, location, versionId, versioning, versions
        }

ref:
http://docs.amazonwebservices.com/AmazonS3/latest/dev/RESTAuthentication.html#ConstructingTheCanonicalizedResourceElement

* lexicographically sorted
* list of sub-resources: acl, location, logging, notification, partNumber, policy, requestPayment, torrent, uploadId, uploads, versionId, versioning, versions and website
* NO NEED to convert to lowercase for sub-resource

changed a little bit to avoid problems

                        if(addrStrings.length > 1) {
                                String[] subResourcesCandidates = addrStrings[1].split("&");
                                for(String subResourceCandidate : subResourcesCandidates) {
                                        String subResourceCandidateHead = subResourceCandidate.split("=")[0];
                                        for(WalrusProperties.SubResource subResource : WalrusProperties.SubResource.values()) {
                                                if(subResourceCandidateHead.equals(subResource.toString())) {
                                                        if(addrString.equals(addrStrings[0])) addrString += "?";
                                                        else addrString += "&";
                                                        //if(!addrString.substring(addrString.length()-1).equals("?")) addrString += "&";
                                                        addrString += subResourceCandidate;
                                                }
                                        }
                                }
                        }
