Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :copy_source (required, String)

    Specifies the source object for the copy operation. You specify the value in one of two formats, depending on whether you want to access the source object through an access point:

    • For objects not accessed through an access point, specify the name of the source bucket and key of the source object, separated by a slash (/). For example, to copy the object reports/january.pdf from the bucket awsexamplebucket, use awsexamplebucket/reports/january.pdf. The value must be URL-encoded.

    • For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>. For example, to copy the object reports/january.pdf through access point my-access-point owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf. The value must be URL encoded.

      * Amazon S3 supports copy operations using Access points only when the source and destination buckets are in the same Amazon Web Services Region.

      • Access points are not supported by directory buckets.

      Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key>. For example, to copy the object reports/january.pdf through outpost my-outpost owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf. The value must be URL-encoded.

    If your bucket has versioning enabled, you could have multiple versions of the same object. By default, x-amz-copy-source identifies the current version of the source object to copy. To copy a specific version of the source object to copy, append ?versionId=<version-id> to the x-amz-copy-source request header (for example, x-amz-copy-source: /awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893).

    If the current version is a delete marker and you don't specify a versionId in the x-amz-copy-source request header, Amazon S3 returns a 404 Not Found error, because the object does not exist. If you specify versionId in the x-amz-copy-source and the versionId is a delete marker, Amazon S3 returns an HTTP 400 Bad Request error, because you are not allowed to specify a delete marker as a version for the x-amz-copy-source.

    Directory buckets - S3 Versioning isn't enabled and supported for directory buckets.

  • :copy_source_if_match (String)

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

    If both of the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request as follows:

    x-amz-copy-source-if-match condition evaluates to true, and;

    x-amz-copy-source-if-unmodified-since condition evaluates to false;

    Amazon S3 returns 200 OK and copies the data.

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

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

    If both of the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request as follows:

    x-amz-copy-source-if-none-match condition evaluates to false, and;

    x-amz-copy-source-if-modified-since condition evaluates to true;

    Amazon S3 returns 412 Precondition Failed response code.

  • :copy_source_if_none_match (String)

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

    If both of the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request as follows:

    x-amz-copy-source-if-none-match condition evaluates to false, and;

    x-amz-copy-source-if-modified-since condition evaluates to true;

    Amazon S3 returns 412 Precondition Failed response code.

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

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

    If both of the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request as follows:

    x-amz-copy-source-if-match condition evaluates to true, and;

    x-amz-copy-source-if-unmodified-since condition evaluates to false;

    Amazon S3 returns 200 OK and copies the data.

  • :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 10 bytes of the source. You can copy a range only if the source object is greater than 5 MB.

  • :sse_customer_algorithm (String)

    Specifies the algorithm to use when encrypting the object (for example, AES256).

    This functionality is not supported when the destination bucket is a directory bucket.

  • :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 S3 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.

    This functionality is not supported when the destination bucket is a directory bucket.

  • :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 that the encryption key was transmitted without error.

    This functionality is not supported when the destination bucket is a directory bucket.

  • :copy_source_sse_customer_algorithm (String)

    Specifies the algorithm to use when decrypting the source object (for example, AES256).

    This functionality is not supported when the source object is in a directory bucket.

  • :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.

    This functionality is not supported when the source object is in a directory bucket.

  • :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 that the encryption key was transmitted without error.

    This functionality is not supported when the source object is in a directory bucket.

  • :request_payer (String)

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    This functionality is not supported for directory buckets.

  • :expected_bucket_owner (String)

    The account ID of the expected destination bucket owner. If the account ID that you provide does not match the actual owner of the destination bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

  • :expected_source_bucket_owner (String)

    The account ID of the expected source bucket owner. If the account ID that you provide does not match the actual owner of the source bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :body (String, StringIO, File)

    Object data.

  • :content_length (Integer)

    Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically.

  • :content_md5 (String)

    The base64-encoded 128-bit MD5 digest of the part data. This parameter is auto-populated when using the command from the CLI. This parameter is required if object lock parameters are specified.

    This functionality is not supported for directory buckets.

  • :checksum_algorithm (String)

    Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request. For more information, see Checking object integrity in the Amazon S3 User Guide.

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

  • :checksum_crc32 (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC-32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :checksum_crc32c (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC-32C checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :checksum_sha1 (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :checksum_sha256 (String)

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • :sse_customer_algorithm (String)

    Specifies the algorithm to use when encrypting the object (for example, AES256).

    This functionality is not supported for directory buckets.

  • :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 S3 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.

    This functionality is not supported for directory buckets.

#wait_until(options = {}) {|resource| ... } ⇒ 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) do |instance|
  instance.state.name == 'running'
end

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

Yield Parameters:

  • resource (Resource)

    to be used in the waiting condition.

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.
