Object / Waiter / wait_until_not_exists

wait_until_not_exists#

S3.Object.wait_until_not_exists(**kwargs)#

Waits until this Object is not exists. This method calls S3.Waiter.object_not_exists.wait() which polls S3.Client.head_object() every 5 seconds until a successful state is reached. An error is raised after 20 failed checks.

Parameters:

  • IfMatch (string) –

    Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.

    If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:

    • If-Match condition evaluates to true, and;

    • If-Unmodified-Since condition evaluates to false;

    Then Amazon S3 returns 200 OK and the data requested.

    For more information about conditional requests, see RFC 7232.

  • IfModifiedSince (datetime) –

    Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.

    If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:

    • If-None-Match condition evaluates to false, and;

    • If-Modified-Since condition evaluates to true;

    Then Amazon S3 returns the 304 Not Modified response code.

    For more information about conditional requests, see RFC 7232.

  • IfNoneMatch (string) –

    Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.

    If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:

    • If-None-Match condition evaluates to false, and;

    • If-Modified-Since condition evaluates to true;

    Then Amazon S3 returns the 304 Not Modified response code.

    For more information about conditional requests, see RFC 7232.

  • IfUnmodifiedSince (datetime) –

    Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.

    If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:

    • If-Match condition evaluates to true, and;

    • If-Unmodified-Since condition evaluates to false;

    Then Amazon S3 returns 200 OK and the data requested.

    For more information about conditional requests, see RFC 7232.

  • Range (string) – HeadObject returns only the metadata for an object. If the Range is satisfiable, only the ContentLength is affected in the response. If the Range is not satisfiable, S3 returns a 416 - Requested Range Not Satisfiable error.

  • ResponseCacheControl (string) – Sets the Cache-Control header of the response.

  • ResponseContentDisposition (string) – Sets the Content-Disposition header of the response.

  • ResponseContentEncoding (string) – Sets the Content-Encoding header of the response.

  • ResponseContentLanguage (string) – Sets the Content-Language header of the response.

  • ResponseContentType (string) – Sets the Content-Type header of the response.

  • ResponseExpires (datetime) – Sets the Expires header of the response.

  • VersionId (string) –

    Version ID used to reference a specific version of the object.

    Note

    For directory buckets in this API operation, only the null value of the version ID is supported.

  • SSECustomerAlgorithm (string) –

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

    Note

    This functionality is not supported for directory buckets.

  • SSECustomerKey (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.

    Note

    This functionality is not supported for directory buckets.

  • SSECustomerKeyMD5 (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.

    Note

    This functionality is not supported for directory buckets.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required

  • RequestPayer (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.

    Note

    This functionality is not supported for directory buckets.

  • PartNumber (integer) – Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a ‘ranged’ HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.

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

  • ChecksumMode (string) –

    To retrieve the checksum, this parameter must be enabled.

    In addition, if you enable checksum mode and the object is uploaded with a checksum and encrypted with an Key Management Service (KMS) key, you must have permission to use the kms:Decrypt action to retrieve the checksum.

Returns:

None
