#copy_from(source, options = {}) ⇒ Object

Copies another object to this object. Use multipart_copy: true for large objects. This is required for objects that exceed 5GB.

Examples:

Basic object copy


bucket = Aws::S3::Bucket.new('target-bucket')
object = bucket.object('target-key')

# source as String
object.copy_from('source-bucket/source-key')

# source as Hash
object.copy_from(bucket:'source-bucket', key:'source-key')

# source as Aws::S3::Object
object.copy_from(bucket.object('source-key'))

Managed copy of large objects


# uses multipart upload APIs to copy object
object.copy_from('src-bucket/src-key', multipart_copy: true)

Parameters:

Options Hash (options):

  • :multipart_copy (Boolean) — default: false —

    When true, the object will be copied using the multipart APIs. This is necessary for objects larger than 5GB and can provide performance improvements on large objects. Amazon S3 does not accept multipart copies for objects smaller than 5MB.

  • :content_length (Integer) —

    Only used when :multipart_copy is true. Passing this options avoids a HEAD request to query the source object size. Raises an ArgumentError if this option is provided when :multipart_copy is false or not set.

  • :copy_source_client (S3::Client) —

    Only used when :multipart_copy is true and the source object is in a different region. You do not need to specify this option if you have provided :content_length.

  • :copy_source_region (String) —

    Only used when :multipart_copy is true and the source object is in a different region. You do not need to specify this option if you have provided a :source_client or a :content_length.

#replication_status ⇒ String

Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (GetObject) or object metadata (HeadObject) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:

  • If requesting an object from the source bucket — Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication.

    For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs. Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf, are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.

  • If requesting an object from a destination bucket — Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.

  • When replicating objects to multiple destination buckets the x-amz-replication-status header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

For more information, see Replication.

#restore ⇒ String

If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see RestoreObject or an archive copy is already restored.

If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:

x-amz-restore: ongoing-request="false", expiry-date="Fri, 21 Dec 2012 00:00:00 GMT"

If the object restoration is in progress, the header returns the value ongoing-request="true".

#upload_file(source, options = {}) {|response| ... } ⇒ Boolean

Uploads a file from disk to the current object in S3.

# small files are uploaded in a single API call
obj.upload_file('/path/to/file')

Files larger than or equal to :multipart_threshold are uploaded using the Amazon S3 multipart upload APIs.

# large files are automatically split into parts
# and the parts are uploaded in parallel
obj.upload_file('/path/to/very_large_file')

The response of the S3 upload API is yielded if a block given.

# API response will have etag value of the file
obj.upload_file('/path/to/file') do |response|
  etag = response.etag
end

You can provide a callback to monitor progress of the upload:

# bytes and totals are each an array with 1 entry per part
progress = Proc.new do |bytes, totals|
  puts bytes.map.with_index { |b, i| "Part #{i+1}: #{b} / #{totals[i]}"}.join(' ') + "Total: #{100.0 * bytes.sum / totals.sum }%" }
end
obj.upload_file('/path/to/file')

Parameters:

  • source (String, Pathname, File, Tempfile) —

    A file on the local file system that will be uploaded as this object. This can either be a String or Pathname to the file, an open File object, or an open Tempfile object. If you pass an open File or Tempfile object, then you are responsible for closing it after the upload completes. When using an open Tempfile, rewind it before uploading or else the object will be empty.

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :multipart_threshold (Integer) — default: 15728640 —

    Files larger than or equal to :multipart_threshold are uploaded using the S3 multipart APIs. Default threshold is 15MB.

  • :thread_count (Integer) — default: 10 —

    The number of parallel multipart uploads. This option is not used if the file is smaller than :multipart_threshold.

  • :progress_callback (Proc) —

    A Proc that will be called when each chunk of the upload is sent. It will be invoked with [bytes_read], [total_sizes]

Yields:

  • (response)

Returns:

  • (Boolean) —

    Returns true when the object is uploaded without any errors.

Raises:

  • (MultipartUploadError) —

    If an object is being uploaded in parts, and the upload can not be completed, then the upload is aborted and this error is raised. The raised error has a #errors method that returns the failures that caused the upload to be aborted.

  true
end

#upload_stream(options = {}, &block) ⇒ Boolean

Uploads a stream in a streaming fashion to the current object in S3.

Passed chunks automatically split into multipart upload parts and the parts are uploaded in parallel. This allows for streaming uploads that never touch the disk.

Note that this is known to have issues in JRuby until jruby-9.1.15.0, so avoid using this with older versions of JRuby.

Examples:

Streaming chunks of data

obj.upload_stream do |write_stream|
  10.times { write_stream << 'foo' }
end

Streaming chunks of data

obj.upload_stream do |write_stream|
  IO.copy_stream(IO.popen('ls'), write_stream)
end

Streaming chunks of data

obj.upload_stream do |write_stream|
  IO.copy_stream(STDIN, write_stream)
end

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :thread_count (Integer) — default: 10 —

    The number of parallel multipart uploads

  • :tempfile (Boolean) — default: false —

    Normally read data is stored in memory when building the parts in order to complete the underlying multipart upload. By passing :tempfile => true data read will be temporarily stored on disk reducing the memory footprint vastly.

  • :part_size (Integer) — default: 5242880 —

    Define how big each part size but the last should be. Default :part_size is 5 * 1024 * 1024.

Returns:

  • (Boolean) —

    Returns true when the object is uploaded without any errors.

Raises:

  • (MultipartUploadError) —

    If an object is being uploaded in parts, and the upload can not be completed, then the upload is aborted and this error is raised. The raised error has a #errors method that returns the failures that caused the upload to be aborted.

#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.

  • (NotImplementedError) —

    Raised when the resource does not
