[jira] [Updated] (JCLOUDS-856) openstack-swift provider mingles blob names that end with slash

["Ka-Hing Cheung (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/JCLOUDS-856?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ka-Hing Cheung updated JCLOUDS-856:
-----------------------------------
    Description: 
Swift (both the old swift and the new openstack-swift providers) deletes trailing slash on listContainer. deleteContainer() also fails if you have a blob with trailing slash.

The mingling is done in MarkersIfDirectoryReturnNameStrategy. Working around that in application is not ideal because metadata.getType() is RELATIVE_PATH could mean a slash was deleted from the end, or the blob's content type is application/directory. It's not clear how to figure out what the real name of the returned objects without probing the store again.
{code:java}
@Test
public void testListObjectWithTrailingSlash() throws InterruptedException {
       BlobStore blobStore = view.getBlobStore();
       String containerName = getContainerName();
       try {
           String key = "a/";
           String etag = blobStore.putBlob(containerName,
                   blobStore.blobBuilder(key).payload("content").build());
           assertThat(etag).isNotNull();
           PageSet<? extends StorageMetadata> res =
                   blobStore.list(containerName, new ListContainerOptions().recursive());
           assertThat(res).hasSize(1);
           StorageMetadata meta = res.iterator().next();
           assertThat(meta.getName()).isEqualTo(key);
       } finally {
           returnContainer(containerName);
       }
   }
{code}
