multipart_upload_part.copy_from({
  copy_source: "CopySource", # required
  copy_source_if_match: "CopySourceIfMatch",
  copy_source_if_modified_since: Time.now,

  request_payer: "requester", # accepts requester
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :copy_source (required, String)

    The name of the source bucket and key name of the source object, separated by a slash (/). Must be URL-encoded.

  • :copy_source_if_match (String)

    Copies the object if its entity tag (ETag) matches the specified tag.

  • :copy_source_if_modified_since (Time, DateTime, Date, Integer, String)

    Copies the object if it has been modified since the specified time.

  • :copy_source_if_none_match (String)

    Copies the object if its entity tag (ETag) is different than the specified ETag.

  • :copy_source_if_unmodified_since (Time, DateTime, Date, Integer, String)

    Copies the object if it hasn't been modified since the specified time.

  • :copy_source_range (String)

    The range of bytes to copy from the source object. The range value must use the form bytes=first-last, where the first and last are the zero-based byte offsets to copy. For example, bytes=0-9 indicates that you want to copy the first ten bytes of the source. You can copy a range only if the source object is greater than 5 GB.

  • :sse_customer_algorithm (String)

    Specifies the algorithm to use to when encrypting the object (e.g., AES256).

  • :sse_customer_key (String)

    Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side​-encryption​-customer-algorithm header. This must be the same encryption key specified in the initiate multipart upload request.

  • :sse_customer_key_md5 (String)

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure the encryption key was transmitted without error.

  • :copy_source_sse_customer_algorithm (String)

    Specifies the algorithm to use when decrypting the source object (e.g., AES256).

  • :copy_source_sse_customer_key (String)

    Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.

  • :copy_source_sse_customer_key_md5 (String)

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure the encryption key was transmitted without error.

  • :request_payer (String)

    Confirms that the requester knows that she or he will be charged for the request. Bucket owners need not specify this parameter in their requests. Documentation on downloading objects from requester pays buckets can be found at http://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html

#wait_until(options = {}, &block) ⇒ Resource

Deprecated.

Use [Aws::S3::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) {|instance| instance.state.name == 'running' }

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {})

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10

    Maximum number of

  • :delay (Integer) — default: 10

    Delay between each

  • :before_attempt (Proc) — default: nil

    Callback

  • :before_wait (Proc) — default: nil

    Callback

Returns:

  • (Resource)

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError)

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError)

    Raised when the resource does not
