CreateRandomPrefixName(std::string const &)

Create a random prefix for object names.

This is useful for operations which require a unique prefix for temporary files.

This is a helper function and it doesn't communicate with GCS, so there is a very small chance that names generated this way aren't unique. The chance should be small enough to fit any error budget.

Given the same prefix, the randomly generated names will have the same length.

Parameter
Name Description
prefix

the prefix of the prefix to be created.

Returns
Type Description
std::string

the random prefix name

DeleteByPrefix(Client &, std::string const &, std::string const &, Options &&...)

Delete objects whose names match a given prefix.

Parameters
Name Description
client

the client on which to perform the operation.

bucket_name

the name of the bucket that will contain the object.

prefix

the prefix of the objects to be deleted.

options

a list of optional query parameters and/or request headers. Valid types for this operation include QuotaUser, UserIp, UserProject and Versions.

typename...
Returns
Type Description
Status

ComposeMany(Client &, std::string const &, std::vector< ComposeSourceObject >, std::string const &, std::string, bool, Options &&...)

Compose existing objects into a new object in the same bucket.

Contrary to Client::ComposeObject, this function doesn't have a limit on the number of source objects.

The implementation may need to perform multiple Client::ComposeObject calls to create intermediate, temporary objects which are then further composed. Due to the lack of atomicity of this series of operations, stray temporary objects might be left over if there are transient failures. In order to allow the user to easily control for such situations, the user is expected to provide a unique prefix parameter, which will become the prefix of all the temporary objects created by this function. Once this function finishes, the user may safely remove all objects with the provided prefix (e.g. via DeleteByPrefix()). We recommend using CreateRandomPrefixName() for selecting a random prefix within a bucket.

Idempotency

This operation is not idempotent. While each request performed by this function is retried based on the client policies, the operation itself stops on the first request that fails.

Example
  namespace gcs = ::google::cloud::storage;
  using ::google::cloud::StatusOr;
  [](gcs::Client client, std::string const& bucket_name,
     std::string const& destination_object_name,
     std::vector<gcs::ComposeSourceObject> const& compose_objects) {
    std::string prefix = gcs::CreateRandomPrefixName(".tmpfiles");
    StatusOr<gcs::ObjectMetadata> composed_object =
        ComposeMany(client, bucket_name, compose_objects, prefix,
                    destination_object_name, false);
    // If this is an effect of some transient unavailability, stray temporary
    // might be left over. You can use `DeleteByPrefix()` with `prefix` as
    // argument to delete them.
    if (!composed_object) throw std::move(composed_object).status();

    std::cout << "Composed new object " << composed_object->name()
              << " in bucket " << composed_object->bucket()
              << "\nFull metadata: " << *composed_object << "\n";
  }
Parameters
Name Description

the client on which to perform the operations needed by this function

bucket_name

the name of the bucket used for source object and destination object.

prefix

prefix for temporary objects created by this function; there should not be any objects with this prefix; in order to avoid race conditions, this function will create an object with this name

destination_object_name

the composed object name.

ignore_cleanup_failures

if the composition succeeds but cleanup of temporary objects fails, depending on this parameter either a success will be returned (true) or the relevant cleanup error (false)

options

a list of optional query parameters and/or request headers. Valid types for this operation include DestinationPredefinedAcl, EncryptionKey, IfGenerationMatch, IfMetagenerationMatchKmsKeyName, QuotaUser, UserIp, UserProject and WithObjectMetadata.

Idempotency

    auto metadata = gcs::ParallelUploadFile(
        std::move(client), file_name, bucket_name, object_name, prefix, false);
    if (!metadata) throw std::move(metadata).status();

  // Use the Mersenne-Twister Engine in this example:
  //   https://en.cppreference.com/w/cpp/numeric/random/mersenne_twister_engine
  // Any C++ PRNG can be used below, the choice is arbitrary.
  using GeneratorType = std::mt19937_64;

  // Create the PRNG with the fetched entropy.
