The ``access_key``, ``secret_key``, and ``token`` properties on this class will always check and refresh credentials if needed before returning the particular credentials. This has an edge case where you can get inconsistent credentials. Imagine this: # Current creds are "t1" tmp.access_key ---> expired? no, so return t1.access_key # ---- time is now expired, creds need refreshing to "t2" ---- tmp.secret_key ---> expired? yes, refresh and return t2.secret_key This means we're using the access key from t1 with the secret key from t2. To fix this issue, you can request a frozen credential object which is guaranteed not to change. The frozen credentials returned from this method should be used immediately and then discarded. The typical usage pattern would be:: creds = RefreshableCredentials(...) some_code = SomeSignerObject() # I'm about to sign the request. # The frozen credentials are only used for the # duration of generate_presigned_url and will be # immediately thrown away. request = some_code.sign_some_request( with_credentials=creds.get_frozen_credentials()) print("Signed request:", request) )r� r� ri r1 r1 r4 r� S s "z-RefreshableCredentials.get_frozen_credentialsr/ )r| r} r~ r r� r r� r` r� � classmethodr� �propertyr �setterr r! r� r r r� r � staticmethodr� r r� r1 r1 r1 r4 r� y s< � " ! r� c s. e Zd ZdZefdd�Zd� fdd� Z� ZS )� DeferredRefreshableCredentialszyRefreshable credentials that don't require initial credentials. refresh_using will be called upon first access. c C s> || _ d | _d | _d | _d | _|| _t�� | _|| _ d | _ d S r/ ) r� r� r� r� r� r� r� r� r� r� r� )r^ r� r� r� r1 r1 r4 r` ~ s z'DeferredRefreshableCredentials.__init__Nc s | j d u rdS tt| ��|�S r� )r� �superr# r r� �� __class__r1 r4 r � s �z-DeferredRefreshableCredentials.refresh_neededr/ )r| r} r~ r r� r` r � __classcell__r1 r1 r% r4 r# y s r# c @ sZ e Zd ZdZddd�Zdd� Zdd� Zd d � Zd d � Zd d� Z dd� Z dd� Z dd� Z dS )�CachedCredentialFetcherr� Nc C s4 |d u ri }|| _ | �� | _|d u r| j}|| _d S r/ )r[ �_create_cache_key� _cache_key� DEFAULT_EXPIRY_WINDOW_SECONDS�_expiry_window_seconds)r^ r- �expiry_window_secondsr1 r1 r4 r` � s z CachedCredentialFetcher.__init__c C � t d��)Nz_create_cache_key()��NotImplementedErrorri r1 r1 r4 r) � � z)CachedCredentialFetcher._create_cache_keyc C s$ |� dd�� tjjd�}|� dd�S )N�:�_�/)�replacer� r� �sep)r^ �filenamer1 r1 r4 �_make_file_safe� s z'CachedCredentialFetcher._make_file_safec C r. )Nz_get_credentials()r/ ri r1 r1 r4 �_get_credentials� r1 z(CachedCredentialFetcher._get_credentialsc C � | � � S r/ )�_get_cached_credentialsri r1 r1 r4 �fetch_credentials� r1 z)CachedCredentialFetcher.fetch_credentialsc C s` | � � }|du r| �� }| �|� nt�d� |d }t|d dd�}|d |d |d |d �S ) z�Get up-to-date credentials.
