Method Details

assertRepoConsistency

public static void assertRepoConsistency(InternalTestCluster testCluster, java.lang.String repoName)

blobExists

public static boolean blobExists(BlobContainer container, java.lang.String blobName) throws java.io.IOException

Throws:

java.io.IOException

assertConsistency

public static void assertConsistency(BlobStoreRepository repository, java.util.concurrent.Executor executor)

Assert that there are no unreferenced indices or unreferenced root-level metadata blobs in any repository. TODO: Expand the logic here to also check for unreferenced segment blobs and shard level metadata

Parameters:

repository - BlobStoreRepository to check

executor - Executor to run all repository calls on. This is needed since the production BlobStoreRepository implementations assert that all IO inducing calls happen on the generic or snapshot thread-pools and hence callers of this assertion must pass an executor on those when using such an implementation.

createDanglingIndex

public static long createDanglingIndex(BlobStoreRepository repository, java.lang.String name, java.util.Set<java.lang.String> files) throws java.lang.InterruptedException, java.util.concurrent.ExecutionException

Throws:

java.lang.InterruptedException

java.util.concurrent.ExecutionException

assertCorruptionVisible

public static void assertCorruptionVisible(BlobStoreRepository repository, java.util.Map<java.lang.String,java.util.Set<java.lang.String>> indexToFiles)

assertBlobsByPrefix

public static void assertBlobsByPrefix(BlobStoreRepository repository, BlobPath path, java.lang.String prefix, java.util.Map<java.lang.String,BlobMetaData> blobs)

mockClusterService

public static ClusterService mockClusterService()

Creates a mocked ClusterService for use in BlobStoreRepository related tests that mocks out all the necessary functionality to make BlobStoreRepository work. Initializes the cluster state as ClusterState.EMPTY_STATE.

Returns:

Mock ClusterService

mockClusterService

public static ClusterService mockClusterService(RepositoryMetaData metaData)

Creates a mocked ClusterService for use in BlobStoreRepository related tests that mocks out all the necessary functionality to make BlobStoreRepository work. Initializes the cluster state with a RepositoriesMetaData instance that contains the given metadata.

Parameters:

metaData - RepositoryMetaData to initialize the cluster state with

Returns:

Mock ClusterService
