The AmazonGlacier component provides a quick way to interface with Amazon's Glacier service.

Syntax

TcsAmazonGlacier

Remarks

The AmazonGlacier component allows you to simply access Amazon's Glacier service. Glacier allows you to create vaults and store archives.

Before using the component you must first have an AWS account and sign up for the Glacier service. To use the component first set AccessKey and SecretKey.

To create a vault call CreateVault. Once the vault is created you are ready to upload archives to store in the vault. Set LocalFile to the file you want to upload and call UploadArchive.

To retrieve an archive you must create a job. Jobs are long running operations and Amazon will notify you when the job is complete. To create a job call CreateJob. Use the SetNotificationInfo method to set notification options at the vault level. You may also supply an Amazon SNS topic to CreateJob to which Amazon will publish notification about the job status.

You can also call CreateJob to create an Inventory Retrieval job to list the contents of a vault.

After the job is complete use GetJobOutput to retrieve the data.

Additionally, multipart uploads are supported through the StartMultipartUpload and CompleteMultipartUpload methods. Various other operations such as DeleteArchive, GetJobInfo, ListJobs, ListMultipartUploads, ListVaults, and more provide additional functionality.

The data must be split into parts with a size (in megabytes) specified by PartSize. The part size must be a megabyte multiplied by a power of 2. For instance 1, 2, 4, and 8 are valid sizes. The minimum part size is 1, the maximum is 4096 (4GB). The default value of PartSize is 1.

Each part must be exactly PartSize megabytes in size except the last part. The last part will be smaller. For instance with a part size of 1, uploading a 10.2 megabyte file will have 11 parts. There will be 10 parts of size 1 MB, and 1 part of size .2 MB.

Parts may be uploaded in parallel by using separate component instances. When uploading a part with UploadPart a part number is specified so the data can be properly re-assembled in order when it reaches the server.

After all parts are uploaded call CompleteMultipartUpload to complete the operation. If parts of the archive were uploaded using separate instances of the component you must first list all parts of the archive by calling ListParts until PartMarker is empty (all parts are returned). Information about the parts is required when completing the multipart upload.

To cancel the operation, call AbortMultipartUpload.

UploadArchive Method (AmazonGlacier Component)

Uploads an archive to a vault.

Syntax

function UploadArchive(VaultName: String; ArchiveDesc: String): String;

Remarks

This method uploads an archive to the vault specified by VaultName. If SetUploadStream was used to specify a valid stream, the archive data will be read from there. If LocalFile is set, the archive data will be read from the specified file. If LocalFile is not set, the data set in ArchiveData will be used.

The ArchiveDesc parameter may be set to a user friendly description of the archive. The description must be less than or equal to 1,024 characters. The allowable characters are 7-bit ASCII without control codes, specifically ASCII values 32-126 decimal or 0x20-0x7E hexadecimal.

This method returns the ArchiveId if the data was successfully uploaded.

UploadPart Method (AmazonGlacier Component)

Uploads a single part in a multipart upload.

Syntax

procedure UploadPart(VaultName: String; UploadId: String; PartNumber: Integer);

Remarks

This method uploads a single part of the multipart upload specified by UploadId.

VaultName is the vault in which the archive is created.

PartNumber identifies this specific part. The first part number is 0. Amazon will re-assemble the archive in the order specified by part numbers.

If SetUploadStream was used to specify a valid stream, the part data will be read from there. If LocalFile is set, the part data will be read from the specified file. If LocalFile is not set, the data set in ArchiveData will be used.

EndTransfer Event (AmazonGlacier Component)

This event fires when a document finishes transferring.

Syntax

type TEndTransferEvent = procedure (
  Sender: TObject;
  Direction: Integer
) of Object;

property OnEndTransfer: TEndTransferEvent read FOnEndTransfer write FOnEndTransfer;

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (AmazonGlacier Component)

Fired when information is available about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

Progress Event (AmazonGlacier Component)

Fires during an upload or download to indicate transfer progress.

Syntax

type TProgressEvent = procedure (
  Sender: TObject;
  Direction: Integer;
  BytesTransferred: Int64;
  TotalBytes: Int64;
  PercentDone: Integer
) of Object;

property OnProgress: TProgressEvent read FOnProgress write FOnProgress;

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the component tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the component will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

SSLServerAuthentication Event (AmazonGlacier Component)

Fired after the server presents its certificate to the client.

Syntax

type TSSLServerAuthenticationEvent = procedure (
  Sender: TObject;
  CertEncoded: String;
  CertEncodedB: TBytes;
  const CertSubject: String;
  const CertIssuer: String;
  const Status: String;
  var Accept: Boolean
) of Object;

property OnSSLServerAuthentication: TSSLServerAuthenticationEvent read FOnSSLServerAuthentication write FOnSSLServerAuthentication;

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (AmazonGlacier Component)

Fired when secure connection progress messages are available.

Syntax

type TSSLStatusEvent = procedure (
  Sender: TObject;
  const Message: String
) of Object;

property OnSSLStatus: TSSLStatusEvent read FOnSSLStatus write FOnSSLStatus;

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (AmazonGlacier Component)

This event fires when a document starts transferring (after the headers).

Syntax

type TStartTransferEvent = procedure (
  Sender: TObject;
  Direction: Integer
) of Object;

property OnStartTransfer: TStartTransferEvent read FOnStartTransfer write FOnStartTransfer;

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (AmazonGlacier Component)

This event is fired while a document transfers (delivers document).

Syntax

type TTransferEvent = procedure (
  Sender: TObject;
  Direction: Integer;
  BytesTransferred: Int64;
  PercentDone: Integer;
  Text: String;
  TextB: TBytes
) of Object;

property OnTransfer: TTransferEvent read FOnTransfer write FOnTransfer;

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

VaultList Event (AmazonGlacier Component)

Syntax

type TVaultListEvent = procedure (
  Sender: TObject;
  const CreationDate: String;
