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 returned after 20 failed checks.

    IfMatch='string',
    IfModifiedSince=datetime(2015, 1, 1),
    IfNoneMatch='string',

)
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.

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

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

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

  • 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.

  • VersionId (string) – VersionId used to reference a specific version of the object.

  • SSECustomerAlgorithm (string) – Specifies the algorithm to use to when encrypting the object (for example, AES256).

  • 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.

  • 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.

    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 Amazon 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.

  • 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 bucket is owned by a different account, 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 ChecksumMode and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the kms:Decrypt action for the request to succeed.

Returns:

None
