FUTURE BREAKING CHANGES:

2022-02-15: retiring legacy targets and rules
  • In 2022-02-15 (or around that time) we are planning to remove a number of backwards compatibility targets names for Bazel and CMake. Specifically:
    • Bazel Users: applications should use the targets at the top-level directory, e.g. //:bigtable, or //:pubsub.
      • All other Bazel targets will be marked as package private in or around 2022-02-15.
    • CMake Users: applications should use the google-cloud-cpp::* targets (e.g. google-cloud-cpp::pubsub).
      • The legacy CMake targets generate warnings if using CMake >= 3.18 (the earliest version that supports deprecation warnings).
      • All exported targets without a google-cloud-cpp:: prefix will be retired in or around 2022-02-15. These include, but are not limited to:
        • Any target starting with googleapis-c++::
        • Any exported targets without a prefix, including: google_cloud_cpp_common, google_cloud_cpp_grpc_utils, bigtable_client, bigtable_protos, firestore_client, pubsub_client, storage_client, spanner_client.
        • Some target aliases, including bigtable::client, bigtable::protos, firestore::client
    • pkg-config users: applications should use the modules starting with google_cloud_cpp
      • All other modules will be retired in or around 2022-02-15
    • Direct users of -l${library} flags: we do not recommend that applications uses -l flags directly, please use pkg-config and/or the target names under CMake or Bazel. We make this recommendation because we do not know of any mechanism to provide backwards compatibility for such flags.
    • If you have any feedback about this change please add comments in #5726
2022-04-01: retiring legacy IAM functions
  • On 2022-04-01 (or shortly after) we are planning to remove a number of IAM functions designed before IAM conditions. These functions do not work with IAM policies that include IAM conditions, and have been marked as deprecated since before 2019-08-01, albeit in Doxygen comments only. Starting with the v1.25.0 release, and depending on your compiler settings, using these functions may issue a deprecation warning at the call site. See #5929 for more details.
2022-10-01: retiring legacy Spanner admin APIs
  • On 2022-10-01 (or shortly after) we are planning to remove the hand-written versions of the Spanner admin APIs. These have been superseded by versions generated automatically from the service definitions. The new APIs can be found in the google/cloud/spanner/admin tree and within the google::cloud::spanner_admin namespace. Starting with the v1.32.0 release, and depending on your compiler settings, using these classes/functions may elicit a deprecation warning. See #7356 for more details.
2022-11-01: remove `v1` and `gcpcxxV1` backward compatibility aliases
  • On 2022-11-01 (or shortly after) we will remove the inline namespace aliases of v1 and gcpcxxV1 that are declared in google/cloud/version.h. These aliases exist because we changed the format of our inline namespace name to include the major, minor, and patch numbers for each release, and we didn't want to break users. Our Doxygen documentation was mistakenly recommending that users include the inline namespace names in their code, but this was also fixed to now recommend against doing so. Users should generally omit the name of our versioned inline namespace name because that will tightly couple their code to a specific release, and will make upgrading to newer versions more difficult. Instead, users should simply omit the inline namespace name, for example, instead of google::cloud::v1::Status use google::cloud::Status. Please update your code to avoid naming the v1 and gcpcxxV1 inline namespace names before 2022-11-01. For more info, see googleapis#7463 and googleapis#5976.
2023-02-01: remove `BigQueryReadReadRowsStreamingUpdater` from `google::cloud::bigquery` namespace
  • On 2023-02-01 (or shortly after) we will remove BigQueryReadReadRowsStreamingUpdater from its declaration in google/cloud/bigquery/read_connection.h and from the google::cloud::bigquery namespace. The function continues to exist but in an internal file and namespace. For status on this see googleapis#8234.

v1.37.0 - TBD

BigQuery

The library has been expanded to include the following services:

Bigtable

BREAKING CHANGE: The bigtable::TableAdminClient interface has changed significantly. Any code that extends this class or calls its experimental public APIs (reset(), Channel()) will be broken. For the most part, this should only affect customers who mock this class in their tests. Code that calls bigtable::MakeAdminClient() or bigtable::CreateDefaultAdminClient() will continue to work as before.

This change will allow us to deliver new features more quickly by reducing the maintenance costs of the library. It also provides a better mocking interface for bigtable::TableAdmin. We apologize if you are inconvenienced by this change.

If only your tests are broken, please use bigtable_admin_mocks::MockBigtableTableAdminConnection in place of bigtable::testing::MockAdminClient. The new mock should be more intuitive because of the differences described below:

MockBigtableTableAdminConnection MockAdminClient
Mocks result of entire retry loop Mocks result of one call in a retry loop
Returns familiar google::cloud:: types Returns grpc:: types

If more than your tests are broken, please use bigtable_admin::BigtableTableAdminClient in favor of bigtable::TableAdmin, and bigtable_admin::BigtableTableAdminConnection in favor of bigtable::AdminClient. These classes will incorporate the newest features of both the Cloud Bigtable Admin API and the C++ client library. For more information on these new classes, see our Architecture Design document.

Again, we apologize for making this breaking change, but we believe it is in the best long-term interest of our customers.

New Libraries

We are introducing client libraries for more (TBD) GCP services. While we do not anticipate any API changes to these libraries before declaring them GA, we are releasing them early in case they elicit some feedback that requires changes.

Expand to see the full list of new libraries...

v1.36.0 - 2022-02

Bazel support

BREAKING CHANGE: We stopped testing with Bazel 3.5 and moved most of our Bazel tests to Bazel 4.0, which is now our minimum supported Bazel version. We also added a bazel-latest build to ensure that we always work with the newest Bazel release (currently 5.0). For more details on the changes, see #8095 and #8099. For more info about Bazel, see https://bazel.build/.

BigQuery

  • feat(generator): merge connection options into client options (#8158)
  • feat(generator): connection respects per call policies (#8013)
  • fix: add mock library aliases (#7844)

Bigtable

BREAKING CHANGE: The bigtable::InstanceAdminClient interface has changed significantly. Any code that extends this class or calls its experimental public APIs (reset(), Channel()) will be broken. For the most part, this should only affect customers who mock this class in their tests. Code that calls bigtable::MakeInstanceAdminClient() or bigtable::CreateDefaultInstanceAdminClient() will continue to work as before.

This change will allow us to deliver new features more quickly by reducing the maintenance costs of the library. It also provides a better mocking interface for bigtable::InstanceAdmin. We apologize if you are inconvenienced by this change.

If only your tests are broken, please use bigtable_admin_mocks::MockBigtableInstanceAdminConnection in place of bigtable::testing::MockInstanceAdminClient. The new mock should be more intuitive because of the differences described below:

MockBigtableInstanceAdminConnection MockInstanceAdminClient
Mocks result of entire retry loop Mocks result of one call in a retry loop
Returns familiar google::cloud:: types Returns grpc:: types

If more than your tests are broken, please use bigtable_admin::BigtableInstanceAdminClient in favor of bigtable::InstanceAdmin, and bigtable_admin::BigtableInstanceAdminConnection in favor of bigtable::InstanceAdminClient. These classes will incorporate the newest features of both the Cloud Bigtable Admin API and the C++ client library. For more information on these new classes, see our Architecture Design document.

Again, we apologize for making this breaking change, but we believe it is in the best long-term interest of our customers.

Storage

BREAKING CHANGE: with this release any use of the storage::internal::ResumableUploadResponse type requires changes. Applications should have little need for this type, outside mocks, so the changes should not affect production code.

Nevertheless, we apologize for the inconvenience, and while we would have preferred to avoid breaking changes, it was inevitable to introduce some breaking changes to fix a data loss bug (see #7835).

If you are affected by this change, you will need to change your tests following this guide. Any place where you return a ResumableUploadResponse needs to change from:

storage::internal::ResumableUploadResource{
  /*upload_session_url=*/std::string{"typically-unused"},
  /*last_committed_byte=*/std::uint64_t{value},
  /*payload=*/absl::nullopt, // or some gcs::ObjectMetadata value
  /*upload_state=*/ResumableUploadResponse::kInProgress, // or kDone
  /*annotations=*/std::string{"typically-unused"}
}

to:

storage::internal::ResumableUploadResource{
  /*upload_session_url=*/std::string{"typically-unused"},
  /*upload_state=*/ResumableUploadResponse::kInProgress, // or kDone
  /*committed_size=*/value + 1, // or absl::nullopt
  /*payload=*/absl::nullopt, // or some gcs::ObjectMetadata value
  /*annotations=*/std::string{"typically-unused"}
}

That is, you need to re-order the fields and increase the value to reflect the number of committed bytes vs. the index in the last committed byte.

Changing the order of the fields was intentional. It will create a build failure, which is easier to detect and repair than a run-time error in your tests.

OTHER CHANGES:

New Libraries

We are introducing client libraries for Cloud Tasks, Secret Manager, and Pub/Sub Lite. These libraries are still under development.

v1.33.0 - 2021-11

⚠️ In this release we have stopped testing with Ubuntu:16.04 as this distribution is no longer supported by Google Cloud. We will gladly consider, but do not commit to accepting, patches to fix build problems on the platform.

ATTENTION: Our Doxygen documentation (e.g. Storage docs) was incorrectly showing the versioned inline namespace name for our symbols (it was v1), implicitly suggesting that users should spell this inline namespace in their own code. This has been corrected. Our Doxygen documentation no longer shows the versioned inline namespace name; instead, it shows users how to correctly spell our symbol names without referencing the versioned inline namespace.

BigQuery

  • feat: create relocatable pkg-config files (#7481)

Bigtable

  • doc: remove inline namespace from doxygen (#7461)
  • fix(bigtable): retry internal errors known to be transient (#7395)

Firestore

BREAKING CHANGE: The experimental Firestore support library that used to live in this repo at google/cloud/firestore has been removed in favor of the canonical library at https://firebase.google.com/docs/reference/cpp. For more info see #7443.

  • cleanup(firestore)!: removes the experimental firestore library (#7468)

  • fix(pubsub): avoid deadlocks in publish flow control (#7313)
  • fix(pubsub): dont std::move PublisherOptions that we are still using (#7270)

Storage

BREAKING CHANGES:

  • We have removed the code generated from storage/v1 protos. These protos were not GA themselves, and the underlying service will be disabled in the near future. Furthermore, the library that used them (the GCS+gRPC plugin) is clearly labeled experimental. Regardless, we apologize if this causes you inconvenience or additional work.

OTHER CHANGES:

  • fix(spanner): fix Client::OverlayQueryOptions() to merge correctly (#7118)

Common Libraries

BREAKING CHANGES:

  • google::cloud::StatusOr<T> had an accessor that returned an lvalue reference to non-const Status, this allowed callers to modify the contained Status and break invariants of the StatusOr class. This function was removed. If your code previously relied on sor.status() = new_status you should change it to sor = new_status. (#7150)

OTHER CHANGES:

  • feat(common): add GrpcChannelArgumentsNativeOption (#7194)
  • feat(common): capture thread that creates log record (#7119)

v1.30.1 - 2021-08

BigQuery

  • Support both google-cloud-cpp::bigquery and deprecated google-cloud-cpp::experimental-bigquery targets.

IAM

  • Support both google-cloud-cpp::iam and deprecated google-cloud-cpp::experimental-iam targets.

v1.30.0 - 2021-08

New GA Libraries

Bigtable:

BREAKING CHANGES:

  • Async* functions in Table that took CompletionQueue& as a parameter have been removed. Users that need to update their code should use the identically named functions which do not require a CompletionQueue&. If users absolutely require a custom CompletionQueue, one can be supplied to the DataClient used to construct the Table, via ClientOptions::DisableBackgroundThreads(CompletionQueue const&). See #2567 for more details.

OTHER CHANGES:

  • The MutationBatcher's default setting for max mutations per batch was reduced from 100k to 1k. The new value achieves better throughput and avoids errors from exhausting the server. ([#7095][googleapis#7095])

Storage:

BREAKING CHANGES:

  • The usage of google::cloud::internal::ObjectReadSource has changed. If your tests mock how the library uses this class you may need to update your tests. We updated the mocking examples to guide you in changing the tests.

OTHER CHANGES:

  • feat(storage): discard handles after an error (#7088)
  • feat(storage): release download handles sooner (#7085)
  • feat(storage): support setting HTTP version (#7077)
  • fix(storage): cleanup interrupted downloads (#7064)
  • fix(storage): avoid crashes after move (#7045)
  • feat(GCS+gRPC): upload checksums with last chunk (#7031)
  • fix(storage): use hash values in InsertObject() (#7025)
  • feat(storage): capture peer address for REST (#6994)
  • feat(GCS+gRPC): option to configure plugin (#6991)
  • feat(GCS+gRPC): checksums on ObjectInsert (#6967)
  • fix(GCS+gRPC): no hashes in Object resource (#6963)

Common Libraries:

  • feat(common): always clog GCP_LOG(FATAL) messages (#7087)
  • feat(common): make GCP_LOG(FATAL) terminate execution (#7058)

Other:

We have removed the super/ directory: google-cloud-cpp remains usable in a super build for a larger project, but we do not believe these files add enough value for the additional complexity. If you prefer to build all the dependencies from source using CMake, we recommend you use a package manager, such as vcpkg.

We have dropped support for Clang < 6.0: to support the latest Google Cloud services we need a version of Protobuf that can compile all the .proto files in https://github.com/googleapis/googleapis. At this time this requires Protobuf >= 3.15, and these versions of Protobuf do not support older versions of the Clang compiler.

v1.29.0 - 2021-07

Misc.

BREAKING CHANGES:

  • In #6243 we stopped compiling the code in generator/ by default in CMake builds. In most cases this should just be a performance win as this code is not used by client libraries. However, if anyone was relying on the generator/ being compiled, it can be re-enabled with -DGOOGLE_CLOUD_CPP_ENABLE_GENERATOR=ON
  • In #6286, we removed the .gcpcxx.pb suffix from filenames emitted from the C++ microgenerator. Any usages of the bigquery, iamcredentials, or logging experimental libraries will require updating of include paths in user code.

v1.26.1 - 2021-04

Storage

  • fix(storage): disable self-signed JWT authentication (#6238)

v1.26.0 - 2021-04

BigQuery

NOTE This release includes an experimental BigQuery Storage Read client library. This library is NOT GA and is likely to have breaking changes in the coming months. Feel free to take a look, file issues, ask questions, and even experiment with it, but do not ship production code using it yet.

  • feature(bigquery): storage library generation (#5989)

Bigtable:

BREAKING CHANGES:

  • bigtable::AdminClient, bigtable::DataClient, and bigtable::InstanceAdminClient each gained a new, pure virtual BackgroundThreadsFactory() member function, requiring anyone who derives from those classes to implement that function. This would typically only affect users who create mock clients for testing purposes.

v1.25.0 - 2021-03

Bigtable:

  • We have marked the asynchronous versions of the administrative functions as deprecated. These functions were experimental and we do not think they add value to our customers. Removing them would simplify the code and free development time for further features and cleanups. More information in #5923.

  • The legacy IAM functions were marked as deprecated via doxygen comments. Now they should generate warnings at the call site, depending on your compiler settings. See #5929 for more information.

  • feat(bigtable): add CMEK attributes to admin APIs (#5921)

  • feat(bigtable): limit default connection pool size (#5881)

  • doc: workarounds for Bazel and path length problems (#5869)

  • doc(bigtable): add configure_connection_pool sample (#5839)

Pub/Sub:

  • Implemented support for "schemas". This feature allows you to define the schema of the messages accepted by a Topic. The schemas can be defined using AVRO or Protocol Buffers. This is a public preview feature of Cloud Pub/Sub, the APIs are found in the ::google::cloud::pubsub_experimental namespace.

Spanner:

  • feat(spanner): Point-In-Time Recovery (PITR) (#5906) This is a major new feature in Spanner, supporting backups and restores at a given timestamp.
  • refactor(spanner): spanner::Timestamp/protobuf::Timestamp conversions… (#5876)
  • feat(spanner): statistics returned for a committed transaction (#5809)

Storage:

  • The legacy IAM functions were marked as deprecated via doxygen comments. Now they should generate warnings at the call site, depending on your compiler settings. See #5929 for more information.

  • doc(storage): Update UBLA documentation to reflect its current status (#5870) It has been GA for a long time, but was still described as not in our comments.

  • fix(storage): remove unneeded dependency (#5798) The backwards compatibility target and package (storage_client) required the googleapis protos.

v1.24.0 - 2021-02

NOTE: We are clarifying our approach to backwards compatibility beyond the C++ API. See the README.md on GitHub for details

Bazel

  • Starting with this release the legacy targets, such as //google/cloud/pubsub:pubsub_client are deprecated and generate warnings recommending a replacement (such as //:pubsub). Note that you may have to prefix the target with the external package name you gave this library, e.g., @github_com_google_cloud_cpp//:pubsub. (#5746)

Bigtable

  • feat(bigtable): restore from backups in other instance (#5754)
  • feat(bigtable): better control over channel refresh (#5753)

Spanner

No user-facing changes.

Storage

BREAKING CHANGES:

  • UniformBucketLevelAccess was known as BucketPolicyOnly during the beta. For compatibility the C++ Cloud Storage library supported both, however BucketPolicyOnly is now completely removed. (#5720)

Other Changes:

  • feat(storage): Support includeTrailingDelimiter in Client::ListObjects (#5713)

Common Libraries

BREAKING CHANGES:

  • refactor!: removed old bigquery code (#5722)

v1.23.0 - 2021-01

Common Libraries

  • fix: crashes during client shutdown (#5701)

Bigtable

  • Removed OpenCensus example. OpenCensus has merged with OpenTracing into OpenTelemetry. The C++ development seems to have stalled, and we not longer believe it will ever be mature enough to recommend for the google-cloud-cpp libraries.

v1.22.0 - 2021-01

v1.21.0 - 2020-12

BREAKING CHANGES:

  • Some "Range" types used in the Storage, Pub/Sub and Spanner APIs lost a constructor that was never intended to be part of their public APIs. Users who were not directly constructing these ranges will not be affected. Also some performance improvements were made to their iterator implementations that could break callers who were relying on unspecified behavior that is not required by the input range concept. The affected types are:
    • google/cloud/storage/list_buckets_reader.h
      • using ListBucketsReader = google::cloud::internal::PaginationRange
    • google/cloud/storage/list_hmac_keys_reader.h

v1.20.0 - 2020-11

Bigtable

No user-facing changes.

Pub/Sub

BREAKING CHANGES:

This is the first GA release of the Pub/Sub library. While breaking changes before GA should be expected, we think highlighting them here is important.

  • Simplify the concurrency control configuration in pubsub::SubscriberOptions. Applications only need to set the maximum number of messages that will be scheduled in parallel.

  • Remove pubsub::AckHandler::ack_id() accessor. We believe application developers should have no need for this field.

  • Rename pubsub::SubscriptionOptions to pubsub::SubscriberOptions as these are bound to a specific subscriber object.

  • Change the pubsub::Subscriber API. A Subscriber is now bound to a specific Cloud Pub/Sub subscription, with a fixed set of SuscriptionOptions, just like a pubsub::Publisher is bound to a specific topic and a set of PublisherOptions. In addition to making publishers and subscribers more symmetrical, this makes the library more consistent with the Cloud Pub/Sub library for other languages. Finally, note that we are planning to rename SubscriptionOptions to SubscriberOptions in a future PR too.

  • Remove option to disable retries in Publisher::Publish. This is redundant as the application can set a "no retries" retry policy. This is more consistent with other Cloud Pub/Sub libraries. We include an example showing how to configure a "no retries" retry policy.

  • Fix inconsistent naming for PublisherOptions attributes controlling the maximum number of messages per batch and the maximum number of bytes per batch.

  • Rename the {Topic,Snapshot,Subscription}MutationBuilder classes, removing Mutation from their names. This makes the C++ library more familiar for Cloud Pub/Sub developers coming from other languages.

  • Simplify the message flow control configuration. Now that the library uses streaming pulls, the low water marks are not used. The application developer simply sets limits for the number of messages (and/or bytes) outstanding. These limits are propagated to the service, and the service will stop streaming if too many messages (or bytes) are outstanding.

Spanner

No user-facing changes.

Storage

BREAKING CHANGES:

  • Our public headers no longer include nlohmann/json.hpp. Please update your code to directly include this header if you need it. We believe it is not a good practice to depend on indirectly included headers, but do feel we should warn our customers of this change.

OTHER CHANGES:

  • Unexpected curl errors will now be retried (#5312)
  • docs: add error handling example from client->ReadObject() (#5274)
  • feat(storage): Create an example for Client::DeleteResumableUpload()
  • doc: prefer UBLA references over bucket-policy-only

Common Libraries

  • Fixed occasional crash on background thread shutdown (#5324)
  • GCP_LOG now serializes its output to std::clog (#5179)

v1.19.0 - 2020-10

Storage

  • fix(storage): consistent computation of XML vs. JSON (#5095) The interaction of ClientOptions::set_endpoint() and the CLOUD_STORAGE_TESTBENCH_ENDPOINT environment variable was inconsistent across endpoints. For JSON endpoints set_endpoint() overrode the CLOUD_STORAGE_TESTBENCH_ENDPOINT value, while for XML endpoints it was the opposite.

    In other libraries the environment variable always wins, so we are changing the behavior here. This behavior was never documented, and it was buggy, therefore it is not a breaking change. Nonetheless, we think the bug (and the fix) is surprising enough to highlight in the CHANGELOG.

  • fix: enable codecvt (UTF-8 support for signed URLs) in MSVC (#5126)

  • fix(storage): avoid stalls with small reads (#5104)

  • feat(storage): disable XML via environment variable (#5100)

  • fix(storage): use correct host header (#5085)

Spanner

  • fix: retry gRPC operations if the connection is unexpectedly terminated (#5087)
  • doc(spanner): use custom retry example in the Doxygen docs (#5164)

Pub/Sub

⚠️ This library is under development and subject to breaking changes without notice.

  • feat(pubsub): wait for callback return and handler (#5161)
  • In addition, @remyabel contributed a number of examples.

v1.18.0 - 2020-09

Storage

  • fix: add missing object ACLs in gRPC client (#5029)
  • fix: work with unknown SSL version in curl (#5037)

Spanner

  • This release includes support for the NUMERIC data type in Cloud Spanner.
  • doc: adapt to new specification for NUMERIC samples (#5049)
  • doc: add spanner_query_with_*_parameter samples (#5016)
  • feat: start using NUMERIC types in database schema (#5025)

Pub/Sub

  • The current release is a preview of the upcoming GA release. While we think the APIs are unlikely to change before GA, we reserve the right to change these APIs for now. This release may need optimization before it is ready for production workloads.

Common Libraries

  • feat: create promises without shared state (#5046)
  • feat: make CompletionQueueImpl mockable [1] (#5036) (#5039) (#5043)
  • feat: support cancels for asynchronous unary RPCs (#5047)

  • fix: remove unneeded dep on absl::variant (#5054)

v1.17.0 - 2020-09

Bigtable

  • doc: update quickstart README files (#4980)

Storage

BREAKING CHANGES

  • fix(storage)!: use nlohmann_json library as any other dependency (#4747)
    • After this change applications using CMake must install the nlohmann_json library. Automatically downloading the library (a) creates problems for package maintainers, (b) requires brittle code to keep the symbols from leaking, and (c) creates problems for users that need newer versions of this library, for example, because they are using a compiler that was not supported by the version we pick.
      • Applications using Bazel or CMake super builds should not be impacted.
      • We have updated our instructions to install this library from source on multiple Linux distributions.
      • Applications using a package manager will need to update their build scripts to add this dependency.
    • In addition, this removes a number of symbols in the google_cloud_cpp_internal_nlohmman_json_3_4_0:: namespace. Obviously we never intended these symbols for public use, but we should have been clearer about it.

Other Changes

  • doc: update quickstart README files (#4980)
  • feat(storage): custom_time in ObjectMetadata (#4901)
  • feat(storage): noncurrent and custom time OLM (#4871)

Spanner

BREAKING CHANGES

  • refactor!: spanner::Timestamp implementing using absl::Time (#4625)
    spanner::Timestamp no longer allows construction from or conversion to a chrono time point with picosecond precision
  • refactor!: use absl::CivilDay for "date" type (#4600)
    absl::CivilDay's constructors are explicit (by design), where as the old spanner::Date 3-arg constructor was not explicit.

Fix issue #4516: atomicity is violated if the first operation in a RW Transaction fails.
If this occurs, the library now explicitly begins a new transaction and retries the failed operation. This ensures subsequent operations using the same Transaction object are in fact executed in the same Spanner transaction.

  • fix: begin a has_begin transaction in Rollback() (#4731)
  • fix: handle ExecuteBatchDml returning OK with no results (#4724)
  • fix: use the updated transaction id in ReadImpl (#4722)
  • fix: explicitly begin failed implicit begin transactions (#4706)
  • feat: handle invalid transactions in ConnectionImpl methods
  • feat: store a Status when invalidating Transactions (#4670)
  • feat: support moving a Transaction into an error state (#4545)

v1.13.0 - 2020-05

NOTICE: This release aligns all the version numbers for Bigtable, Storage, the common libraries, and the repository itself. From this point on all releases will include a single version number. Note that there is a gap in the version numbers for Bigtable and the repository changes from v0.21.0 to v1.13.0

BREAKING CHANGES

  • The common library inlined namespace changed to v0 to v1, moving all the symbols from google::cloud::v0 to google::cloud::v1. Applications that explicitly referred to the inlined namespace would be affected by this change. That is, code that uses google::cloud::v0::Foo instead of google::cloud::Foo would need to be modified. We apologize if this has impacted you, and recommend that applications do not refer to the inlined namespace in the future.

Bigtable

BREAKING CHANGES

See above regarding the common library inlined namespace.

OTHER CHANGES

  • cleanup: the library now links against the common libraries included in this repository, applications developers should not install the standalone common libraries in the (now archived) google-cloud-cpp-common repository.
  • feat: compile bigtable benchmarks with Bazel (#3884)
  • feat: implement table level IAM policy for bigtable(async) (#3829)
  • feat: implement table level IAM policy for bigtable (#3751)
  • refactor: synchronize version numbers for all libraries (#3710)
  • feat: change READMEs and quickstart programs (#3690) The google/cloud/bigable/quickstart/ directory contains a sample project for CMake and Bazel that uses the Cloud Bigtable C++ client library as we expect application developers would.

Storage

BREAKING CHANGES

See above regarding the common library inlined namespace.

  • fix!: use correct type for generation numbers (#3870) This changes the type of two fields from google::cloud::optional<long> to google::cloud::optional<std::int64_t>. With MSVC this is not a backwards compatible change (storing the result of .value() into a long now loses precision). However, on that platform the fields were not usable, they could not store the values that are typically generated by the production environment. We apologize to any customers affected by this change, but we think it is unlikely that anybody used the field on that platform.

OTHER CHANGES

  • cleanup: the library now links against the common libraries included in this repository, applications developers should not install the standalone common libraries in the (now archived) google-cloud-cpp-common repository.
  • feat: implement POST policy signatures. Applications can use the Google Cloud Storage C++ client library to create POST objects, which allow uploading using HTML forms.
  • feat: change READMEs and quickstart programs (#3690) The google/cloud/bigable/quickstart/ directory contains a sample project for CMake and Bazel that uses the Cloud Bigtable C++ client library as we expect application developers would.
  • fix: use network to check if running inside Google (#3959) With this change applications running on Google App Engine Flex (GAEF), Google Kubernetes Engine (GKE), or Cloud Run can use the Google Default Credentials.
  • fix: build problems on MSVC x86 (#3916)
  • fix: do not use CURL_SHARE features (#3860)
  • chore: upgrade libcurl to v7.69.1 (#3851)

Common Libraries

BREAKING CHANGES

See above regarding the common library inlined namespace.

OTHER CHANGES

No other interesting changes in the common libraries with this release.

v0.21.0 - 2020-04

NOTICE: This repo will soon contain the code for all the other related google-cloud-cpp-* repos. As a new monorepo (#3612), the versioning of this repo will be changing to have a single per-repo version. The per-library version numbers will be removed in favor of the repo version. See googleapis#3615 for more info.

Bigtable (v1.9.x)

BREAKING CHANGES

  • fix!: moved IAM-related symbols to the correct inlined namespace (#3453) Most users should not notice any difference, but those that explicitly referenced symbols through the google::cloud::bigtable::v0 namespace may need to switch to google::cloud::bigtable (the recommended approach) or google::cloud::bigtable::v1. We apologize if this causes you inconvenience.

Storage (v1.12.x)

BREAKING CHANGES

  • fix!: moved IAM-related symbols to the correct inlined namespace (#3453) Most users should not notice any difference, but those that explicitly referenced symbols through the google::cloud::storage::v0 namespace may need to switch to google::cloud::storage (the recommended approach) or google::cloud::storage::v1. We apologize if this causes you inconvenience.

v0.15.0 - 2019-11

Build

BREAKING CHANGE:

  • The common libraries have been moved to the google-cloud-cpp-common repository. While this may not be a technically breaking change (the API and ABI remain unchanged, the include paths are the same), it will require application developers to change their build scripts.

v0.11.0 - 2019-07

Bigtable (v1.0.0)

  • bug: the library will return an error instead of simply discarding unknown IAM fields.
  • feature: update googleapis protos to a more recent version.
  • cleanup: marked rarely used CMake options as advanced. They will no longer show up by default in your CMake UI.
  • Several internal cleanups, such as removing unused code in google::cloud::bigtable::internal, fixing constant names to follow the Google Style Guide, simplify the generation of version metadata, make it easier to import the code into Google, turned on -Wextra for our builds, moved the sanitizer builds to Bazel, and refactoring generic gRPC utilities to a new common library.

Storage (v1.2.0)

  • Breaking Change: we accidentally left two functions in the public API, they are now removed. These functions were used to convert google::cloud::storage::ServiceAccount classes to and from JSON objects.
  • Breaking Change: we removed the functions in google::cloud::storage::IdempotencyPolicy for internal::InsertObjectStreamingRequest. This class is no longer used and the functions are unnecessary. This breakage only affects applications that define a custom IdempotencyPolicy.
  • bug: Fixed WriteObject() to actually retry the upload for each chunk, not just retry the creation of the upload session.
  • feature: add examples showing how to mock a google::cloud::storage::Client.
  • feature: allow applications to load service account credentials from the standard locations, but also change the scopes and subject as the credentials are loaded. Thanks to @timford for contributing this fix.
  • bug: resuming an already finalized upload was not working correctly. Now the library restores the stream, but the stream is immediately closed (it is incorrect to write more data), and has the object metadata immediately available. Thanks to @Jseph for contributing this fix.
  • bug: on Windows, storage::Client::UploadFile() and storage::Client::DownloadFile() were always treating the files as text, which meant their contents were transformed in unexpected ways. They are now always treated as binary.
  • bug: we were still leaking a few macros from the nlohmann json library to the user's namespace. This is now fixed. Thanks to @remyabel for helping us with this.
  • feature: reduce data copies during download.
  • bug: return an error if the IAM bindings contain unknown fields, previously the library was discarding these fields.
  • Several internal cleanups, such as fixing constant names to match the Google Style Guide, simplify the generation of version metadata, make the integration tests more reliable by using several service accounts for each run, use -Wextra in our builds, and a few more.

v0.10.0 - 2019-06

Bigtable (v0.10.0)

  • Breaking Changes
    • The return type for WaitForConsistencyCheck() was a future<StatusOr<bool>> where most related functions return a bigtable::Consistency enum.
    • Table::CheckAndMutateRow returns StatusOr<bool> to indicate which branch of the predicate was taken in the atomic change. Meanwhile, AsyncCheckAndMutateRow() returned a future<StatusOr<proto-with-long-name>>. Changed the async and sync versions to return future<StatusOr<MutationBranch>>. MutationBranch is an enum as StatusOr<bool> is too eay to use incorrectly.
    • Removed the Collection template parameter from Table::SampleRows.
    • Fixed the last function, WaitForConsistencyCheck, that returned std::future to return google::cloud::future<>. The function name changed too, to be more consistent with similar functions.
    • Remove all the "strong types" for bigtable, such as InstanceId, ClusterId, TableId, etc. This changed some of the constructors for bigtable::Table and several member functions in bigtable::Table, bigtable::TableAdmin, and bigtable::InstanceAdmin.
  • Changes:
    • Implemented TableAdmin::AsyncWaitForConsistency.
    • Implemented Table::AsyncReadRows.
    • DeleteAppProfile defaults to ignore_warnings=true.

Storage (v1.1.0)

  • Implemented option to read an object starting from an offset.
  • Automatically restart downloads on error. With this change the download is restarted from the last received byte, and using the object generation used in the original download as well. (#2693)
  • Bugfixes:
    • Service account credentials not refreshing properly. (#2691)
    • Fix build for macOS+CMake. (#2698)
    • WriteObject now supports empty streams. (#2714)

v0.9.0 - 2019-05

Bigtable (v0.9.0)

  • Breaking Changes
    • Return google::cloud::future from InstanceAdmin functions: this is more consistent with all other functions returning futures.
    • Remove unused bigtable::GrpcError: the library no longer raises this exception, any code trying to catch the exception should be modified to handle errors via StatusOr<T>.
    • Remove Snapshot-related functions, tests, examples, etc.: this is functionality in Cloud Bigtable was controlled by an allow-list, and it is no longer expected to reach GA.
  • Continue to implement more async APIs (Async*() methods) for the InstanceAdmin, TableAdmin, and Table classes (Note: These are not yet stable)
  • Bugfixes:
    • Need ignore_warnings to actually delete an AppProfile.
    • Fix portability/logical errors in shell scripts.
    • Fix a race condition in MutationBatcher.
  • Implemented a number of previously missing code samples.

Common (v0.7.0)

  • Support move-only callables in future<T>
  • Avoid std::make_exception_ptr() in future_shared_state_base::abandon().

Storage (v1.0.0)

  • Declared GA and updated major number.
  • Support signed policy documents.
  • Support service account key files in PKCS#12 format (aka .p12).
  • Support signing URLs and policy documents using the SignBlob API, this is useful when using the default service account in GCE to sign URLs and policy documents.

v0.8.1 - 2019-04

Bigtable (v0.8.x)

  • Use SFINAE to constrain applicability of the BulkMutation(M&&...) ctor.

Common

  • Avoid std::make_exception_ptr() when building without exceptions.

v0.8.0 - 2019-04

Bigtable (v0.8.x)

  • Breaking change: Table::BulkApply now returns a std::vector<FailedMutation> instead of throwing an exception.
  • In the future we will remove all the google::cloud::bigtable::noex::* classes. We are moving the implementation to google::cloud::bigtable::*.
  • Continuing to implement more async APIs (Note: These are not yet stable):
    • InstanceAdmin::AsyncDeleteInstance
    • Table::AsyncCheckAndMutateRow
    • TableAdmin::AsyncDeleteTable
    • TableAdmin::AsyncModifyColumnFamilies
  • BulkMutator now returns more specific errors instead of generic UNKNOWN.
  • Improved install instructions, which are now tested with our CI builds.
  • CMake-config files now work without pkg-config.
  • Removed the googleapis submodule. The build system now automatically downloads all deps.
  • No longer throw exceptions from ClientOptions.

Common

  • Removed the googleapis submodule. The build system now automatically downloads all deps.

Storage (v0.6.x)

  • Added initial support for HMAC key-related functions.
  • Added support for V4 signed URLs.
  • Improved install instructions, which are now tested with our CI builds.
  • CMake-config files now work without pkg-config.
  • No longer throw exceptions from ClientOptions.

  • Add streaming to (Async)BulkMutator.
  • Implement a helper class (MutationBatcher) to automatically batch and manage outstanding bulk mutations.
  • Add bigtable::Cell constructors without labels argument.
  • Implementation of RowSet example using discontinuous keys.
  • List{Instances,Clusters} return failed_locations.
  • First version of async Apply batching.
  • Keep Apply callbacks in MutationData.

Common

  • Breaking change: Make google::cloud::optional::operator bool() explicit.
  • Add google::cloud::optional value conversions that match std::optional.
  • Stop using grpc's DO_NOT_USE enum.
  • Remove ciso646 includes to force traditional spellings.
  • Change std::endl -> "\n".
  • Enforce formatting of .cc files.

Storage (v0.5.x)

  • Properly handle subresources in V2 signed URLs.
  • Allow specifying non-default ServiceAccountCredentials scope and subject.
  • Add make install instructions.
  • Change the storage examples to throw a std::runtime_error on failure.
  • Add Bucket Policy Only samples.

v0.6.1 - 2019-02

Bigtable (v0.6.x)

  • No changes from v0.6.0

Common

  • No changes from v0.6.0

Storage (v0.4.x)

  • The library is now Beta. We no longer expect changes to the API.
  • No other changes from v0.6.0

v0.6.0 - 2019-02

Bigtable (v0.6.x)

  • Moved repo organization from GoogleCloudPlatform -> googleapis.
  • Implemented several more async functions.
  • Breaking change: Started migrating functions to StatusOr and away from throwing exceptions.
  • Several fixes to bulk mutator (#1880)
  • Disabled make install for external projects.
  • Row now has a move constructor.
  • Increased default message length limit.
  • Now testing build with libc++ on Linux.
  • Fixed some bugs found by Coverity scans.

Common

  • Fixed some documentation.
  • Breaking change: Removed StatusOr<void>.
  • Updated StatusOr documentation.
  • Fixed some (minor) issues found by coverity.

Storage (v0.4.x)

  • Breaking change: Removed almost all exception throwing in favor of StatusOr<T> return values.
  • Lots of cleanup to documentation and example code.
  • Avoids use of StatusOr::value() when the validity was already checked.
  • Client::ListBuckets() now directly returns ListBucketsReader, because it cannot fail so StatusOr was not needed.
  • Removed support for StatusOr<void>; changed usages to return Status instead.
  • 502s are now retryable errors from GCS.
  • Breaking change: LockBucketRetentionPolicy returns a BucketMetadata now instead of void.
  • Cleaned up documentation and example code.
  • Disabled make install for external projects.
  • Moved repo organization from GoogleCloudPlatform -> googleapis.
  • Moved some internal-only APIs out of public interfaces.
  • Fixed resuming uploads when the server responds with a 308.

v0.5.0 - 2019-01

Bigtable (v0.5.x)

  • Restore support for gcc-4.8.
  • @remyabel cleaned up some hard-coded zone names in the examples.
  • More experimental asynchronous APIs, including AsyncReadRows. Note that we expect to change all these experimental APIs as described in #1543.
  • @remyabel contributed changes to disable the unit and integration tests. This can be useful for package maintainers.
  • New Bigtable filter wrapper that accepts a single column.
  • Breaking Change: remove the as_proto_move() member functions in favor of as_proto() &&. With the latter newer compilers will warn if the object is used after the destructive operation.

Common

  • Support compiling with gcc-4.8.
  • Fix GCP_LOG() macro so it works on platforms that define a DEBUG pre-processor symbol.
  • Use different PRNG sequences for each backoff instance, previously all the clones of a backoff policy shared the same sequence.
  • Workaround build problems with Xcode 7.3.

Storage (v0.3.x)

  • Try to use the exception mask in the IOStream classes (storage::ObjectReadStream and storage::ObjectWriteStream). This allows applications to check errors locally via rdstate(). Note that applications that disable exceptions altogether must check the status() member function for these IOStream classes. It is impossible to set the rdstate() for all failures when exceptions are disabled.
  • Support reading only a portion of a Blob.
  • Support building with gcc-4.8.
  • Many internal changes to better support applications that disable exceptions. A future release will include APIs that do not raise exceptions for error conditions.
  • @remyabel contributed changes to disable the unit and integration tests. This can be useful for package maintainers.
  • Implement a function to create signed URLs (Client::CreateV2SignedUrl).
  • Support resumable uploads in any upload operation.

v0.4.0 - 2018-12

Bigtable (v0.4.x)

  • More experimental asynchronous APIs, note that we expect to change all these experimental APIs as described in #1543.
  • Most of the admin operations now have asynchronous APIs.
  • All asynchronous APIs in noex::* return an object through which applications can request cancellation of pending requests.
  • Prototype asynchronous APIs returning a google::cloud::future<T>, applications can attach callbacks and/or block on a google::cloud::future<T>.

Common

  • Implement google::cloud::future<T> and google::cloud::promise<T> based on ISO/IEC TS 19571:2016, the "C++ Extensions for Concurrency" technical specification, also known as "futures with continuations".

Storage (v0.2.x)

  • Use resumable uploads for large files in Client::UploadFile().
  • Implement support for the userIp optional query parameter.
  • BREAKING CHANGE Client::RewriteObject(), Client::CopyObject(), and Client::ComposeObject no longer require the ObjectMetadata argument. Instead use WithObjectMetadata(), which can be omitted if you do not need to set any metadata attributes in the new object.
  • When using OpenSSL-1.0.2 the client library needs to configure the locking callbacks for OpenSSL. However, the application may disable this behavior if the application developer is going to use their own locking callbacks.
  • When refreshing OAuth2 access tokens the client library uses the same retry and backoff policies as used for the request itself.
  • Applications can set object metadata attributes via the WithObjectMetadata optional argument to Client::InsertObjectMedia().
  • Applications can configure the library to only retry idempotent operations.
  • The client library can use Google Compute Engine credentials to access the service.

v0.3.0 - 2018-11

This is the v0.3.0 release of the Google Cloud C++ Client Libraries.

Bigtable (v0.3.0)

  • Experimental asynchronous APIs.
  • Include an example that illustrates how to use OpenCensus and the Cloud Bigtable C++ client library.
  • Several cleanups around dependency management with CMake.
  • Jason Zaman contributed improvements and fixes to support soversion numbers with CMake.
  • Lots of improvements to the code coverage in the examples and tests.
  • Fixed multiple documentation issues, including a much better landing page in the Doxygen documentation.

Common

  • google::cloud::optional<T> an intentionally incomplete implementation of std::optional<T> to support C++11 and C++14 users.
  • Applications can configure google::cloud::LogSink to enable logging in some of the libraries and to redirect the logs to their preferred destination. The libraries do not enable any logging by default, not even to stderr.
  • google::cloud::SetTerminateHandler() allows applications compiled without exceptions, but using the APIs that rely on exceptions to report errors, to configure how the application terminates when an unrecoverable error is detected by the libraries.

Storage (v0.1.x)

  • Automatically compute MD5 hashes and CRC32C checksums when objects are uploaded and downloaded. Any hash or checksum mismatched results in an exception. Applications can MD5 hashes, CRC32C checksums or both on any request.
  • Parse Bucket lock and retention policy attributes in object and bucket metadata.
  • Add APIs to upload and download files with a single function call.
  • Improved the error messages generated when the credentials file is missing or has invalid contents.
  • Jason Zaman contributed improvements and fixes to support soversion numbers with CMake.
