Subject [jira] [Resolved] (JCLOUDS-1173) List method has different behavior on different cloud providers
Date Tue, 18 Oct 2016 18:55:58 GMT

     [ https://issues.apache.org/jira/browse/JCLOUDS-1173?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Gaul resolved JCLOUDS-1173.
----------------------------------
       Resolution: Fixed
         Assignee: Andrew Gaul
    Fix Version/s: 2.0.0

Glad 2.0.0-SNAPSHOT works for you.  Note that you do not have to call {{createDirectory}}
-- directories are largely a jclouds fiction and blobstores actually support this functionality
via prefix and delimiter.  Directories will go away in 2.1.0.

> I'm seeing different behavior for the BlobStore list method of aws-s3 and transient.
 On aws-s3 the PageSet contains the directory itself and on azure and transient it does not.
 
> The example below shows that transient gives a size of 1 and aws-s3 gives a size of 2
even though they are setup exactly the same.
