Description

If you create a directory in azureblob or transient, blobexists will return true for that directory name. It does not seem to filter out the marker blobs. If you create a directory in aws-s3 and call blobexists on that directory name it will return false.

Example code below

import org.jclouds.ContextBuilder;
import org.jclouds.blobstore.BlobStore;
import org.jclouds.blobstore.BlobStoreContext;

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.DefaultAWSCredentialsProviderChain;
//Test for equals behavior
public class DirectoryExistsTest {
	public static void main(String[] args) {
		String containerName = "test.container";
		String testDirectory = "testDirectory";
		AWSCredentials creds = new DefaultAWSCredentialsProviderChain().getCredentials();
		//Setup the contexts
		BlobStoreContext transientContext = ContextBuilder.newBuilder("transient")
				.credentials(creds.getAWSAccessKeyId(), creds.getAWSSecretKey())
				.build(BlobStoreContext.class);
		BlobStoreContext awsS3Context = ContextBuilder.newBuilder("aws-s3")
				.credentials(creds.getAWSAccessKeyId(), creds.getAWSSecretKey())
				.build(BlobStoreContext.class);
		//Setup the blobstores
		BlobStore transientStore = transientContext.getBlobStore();
		BlobStore awsS3Store = awsS3Context.getBlobStore();
		//Setup the containers
		transientStore.createContainerInLocation(null, containerName);
		awsS3Store.createContainerInLocation(null, containerName);
		//Setup the directories
		transientStore.createDirectory(containerName, testDirectory);
		awsS3Store.createDirectory(containerName, testDirectory);

		System.out.println("Transient directory should exist " + transientStore.directoryExists(containerName, testDirectory));
		System.out.println("Transient blob should not exist " + transientStore.blobExists(containerName, testDirectory));
		System.out.println("aws-s3 directory should exist " + awsS3Store.directoryExists(containerName, testDirectory));
		System.out.println("aws-s3 blob should not exist " + awsS3Store.blobExists(containerName, testDirectory));
	}
