v1.30.0

v1.30.0 Release

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.

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:

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.

v0.8.0 Release

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.
• Handle object names with slashes.
• Added ObjectMetadata::set_storage_class
• Added support for policy documents.

v0.7.0 Release

Bigtable (v0.7.x)

• Breaking change: Return StatusOr<> from TableAdmin and InstanceAdmin
  operations to signal errors.
• 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.

v0.6.0 Release

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 (googleapis#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 Release

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.
