From af245d67feb82f9099d5d225ef24149ae1811fee Mon Sep 17 00:00:00 2001 From: Shri Javadekar Date: Mon, 7 Oct 2013 14:04:38 -0700 Subject: [PATCH] JCLOUDS-334. Return correct status while creating containers in Swift. BlobStore.createContainerInLocation is supposed to return True if the container was newly created and False if the container already existed. This commit makes that happen for Swift blobstores. --- .../swift/CommonSwiftAsyncClient.java | 3 ++ .../swift/SwiftClientExpectTest.java | 31 +++++++++++++++ .../http/functions/ReturnTrueIf201.java | 38 +++++++++++++++++++ 3 files changed, 72 insertions(+) create mode 100644 core/src/main/java/org/jclouds/http/functions/ReturnTrueIf201.java diff --git a/apis/swift/src/main/java/org/jclouds/openstack/swift/CommonSwiftAsyncClient.java b/apis/swift/src/main/java/org/jclouds/openstack/swift/CommonSwiftAsyncClient.java index 9ac73c7486..988b95399a 100644 --- a/apis/swift/src/main/java/org/jclouds/openstack/swift/CommonSwiftAsyncClient.java +++ b/apis/swift/src/main/java/org/jclouds/openstack/swift/CommonSwiftAsyncClient.java @@ -41,6 +41,7 @@ import org.jclouds.blobstore.BlobStoreFallbacks.NullOnKeyNotFound; import org.jclouds.blobstore.binders.BindMapToHeadersWithPrefix; import org.jclouds.blobstore.domain.PageSet; import org.jclouds.http.functions.ParseETagHeader; +import org.jclouds.http.functions.ReturnTrueIf201; import org.jclouds.http.options.GetOptions; import org.jclouds.openstack.swift.SwiftFallbacks.TrueOn404FalseOn409; import org.jclouds.openstack.swift.binders.BindIterableToHeadersWithContainerDeleteMetadataPrefix; @@ -142,6 +143,7 @@ public interface CommonSwiftAsyncClient extends Closeable { */ @Named("CreateContainer") @PUT + @ResponseParser(ReturnTrueIf201.class) @Path("/{container}") ListenableFuture createContainer(@PathParam("container") String container, CreateContainerOptions... options); @@ -161,6 +163,7 @@ public interface CommonSwiftAsyncClient extends Closeable { */ @Named("CreateContainer") @PUT + @ResponseParser(ReturnTrueIf201.class) @Path("/{container}") ListenableFuture createContainer(@PathParam("container") String container); diff --git a/apis/swift/src/test/java/org/jclouds/openstack/swift/SwiftClientExpectTest.java b/apis/swift/src/test/java/org/jclouds/openstack/swift/SwiftClientExpectTest.java index 61159bda45..e217445b51 100644 --- a/apis/swift/src/test/java/org/jclouds/openstack/swift/SwiftClientExpectTest.java +++ b/apis/swift/src/test/java/org/jclouds/openstack/swift/SwiftClientExpectTest.java @@ -54,6 +54,37 @@ public class SwiftClientExpectTest extends BaseSwiftExpectTest { assertTrue(clientWhenContainerExists.containerExists("foo")); } + @Test + public void testCreateContainerReturnStatus() { + String containerName = "foo"; + HttpRequest createContainerRequest = HttpRequest.builder() + .method("PUT") + .endpoint(swiftEndpointWithHostReplaced + "/" + containerName) + .addHeader("X-Auth-Token", authToken).build(); + HttpResponse createContainerResponse = HttpResponse.builder() + .statusCode(201) + .build(); + + SwiftClient clientWhenNonExistingContainer = requestsSendResponses( + authRequest, authResponse, createContainerRequest, + createContainerResponse); + + assertTrue(clientWhenNonExistingContainer.createContainer( + containerName)); + + // Try creating the same container again.
