---------------------------------------
Summary: AWS S3, sign for authorization header failed if query
part contains special chars
Key: JCLOUDS-1631
URL: https://issues.apache.org/jira/browse/JCLOUDS-1631
Project: jclouds
Issue Type: Bug
Components: jclouds-blobstore
Affects Versions: 2.5.0
Reporter: Maksim Hadalau
Problem description:
Can not list blobs for aws-s3 provider if prefix contains special chars %/&
Steps to reproduce:
try to list blobs with following prefix:
"Folder (`~!@#$%^&*-_+[]'|<>.?) Name/"
Actual behavior:
Error: URLDecoder: Incomplete trailing escape (%) pattern
Expected behavior:
provided prefix must be listed
Problem location:
`AWSRequestAuthorizeSignatureV4.signForAuthorizationHeader()`
Multimap<String, String> queryMap =
queryParser().apply(request.getEndpoint().getQuery());
request.getEndpoint().getQuery() - returns a decoded query string
however queryParser() require encoded one
Fix:
Multimap<String, String> queryMap =
queryParser().apply(request.getEndpoint().getRawQuery());
When jclouds generates a request to the AWS it encodes prefix (encoding all
special chars in it, including % and &), however calling `getQuery()` returns
decoded version of query string which lead to unpredictable behavior.
P.S. required patch in 2.5.x if possible
