The resumable errors are DEADLINE_EXCEEDED, + * INTERNAL, and UNAVAILABLE. For each case, the client should use binary + * exponential backoff before retrying. Additionally, writes can be + * resumed after RESOURCE_EXHAUSTED errors, but only after taking + * appropriate measures, which may include reducing aggregate send rate + * across clients and/or requesting a quota increase for your project. + * - If the call to `WriteObject` returns `ABORTED`, that indicates + * concurrent attempts to update the resumable write, caused either by + * multiple racing clients or by a single client where the previous + * request was timed out on the client side but nonetheless reached the + * server. In this case the client should take steps to prevent further + * concurrent writes (e.g., increase the timeouts, stop using more than + * one process to perform the upload, etc.), and then should follow the + * steps below for resuming the upload. + * - For resumable errors, the client should call `QueryWriteStatus()` and + * then continue writing from the returned `persisted_size`. This may be + * less than the amount of data the client previously sent. Note also that + * it is acceptable to send data starting at an offset earlier than the + * returned `persisted_size`; in this case, the service will skip data at + * offsets that were already persisted (without checking that it matches + * the previously written data), and write only the data starting from the + * persisted offset. This behavior can make client-side handling simpler + * in some cases. * The service will not view the object as complete until the client has * sent a `WriteObjectRequest` with `finish_write` set to `true`. Sending any * requests on a stream after sending a request with `finish_write` set to * `true` will cause an error. The client **should** check the response it * receives to determine how much data the service was able to commit and * whether the service views the object as complete. + * Attempting to resume an already finalized object will result in an OK + * status, with a WriteObjectResponse containing the finalized object's + * metadata. * */ public io.grpc.stub.StreamObserver writeObject( diff --git a/proto-google-cloud-storage-v2/clirr-ignored-differences.xml b/proto-google-cloud-storage-v2/clirr-ignored-differences.xml index af53e7fa5e..4a3695b3ba 100644 --- a/proto-google-cloud-storage-v2/clirr-ignored-differences.xml +++ b/proto-google-cloud-storage-v2/clirr-ignored-differences.xml @@ -17,4 +17,15 @@ * *CommonRequestParams*(*) + + 7012 + com/google/storage/v2/*OrBuilder + * *Etag*(*) + + + 7012 + com/google/storage/v2/*OrBuilder + * *CustomPlacementConfig*(*) + + diff --git a/proto-google-cloud-storage-v2/src/main/java/com/google/storage/v2/Bucket.java b/proto-google-cloud-storage-v2/src/main/java/com/google/storage/v2/Bucket.java index c5893b6f34..1c12c9ddf6 100644 --- a/proto-google-cloud-storage-v2/src/main/java/com/google/storage/v2/Bucket.java +++ b/proto-google-cloud-storage-v2/src/main/java/com/google/storage/v2/Bucket.java @@ -40,6 +40,7 @@ private Bucket(com.google.protobuf.GeneratedMessageV3.Builder builder) { private Bucket() { name_ = ""; bucketId_ = ""; + etag_ = ""; project_ = ""; location_ = ""; locationType_ = ""; @@ -353,6 +354,23 @@ private Bucket( case 200: { satisfiesPzs_ = input.readBool(); + break; + } + case 210: + { + com.google.storage.v2.Bucket.CustomPlacementConfig.Builder subBuilder = null; + if (customPlacementConfig_ != null) { + subBuilder = customPlacementConfig_.toBuilder(); + } + customPlacementConfig_ = + input.readMessage( + com.google.storage.v2.Bucket.CustomPlacementConfig.parser(), + extensionRegistry); + if (subBuilder != null) { + subBuilder.mergeFrom(customPlacementConfig_); + customPlacementConfig_ = subBuilder.buildPartial(); + } + break; } case 218: @@ -376,6 +394,13 @@ private Bucket( autoclass_ = subBuilder.buildPartial(); } + break; + } + case 234: + { + java.lang.String s = input.readStringRequireUtf8(); + + etag_ = s; break; } default: @@ -11600,7 +11625,8 @@ public interface LoggingOrBuilder * * *
