This is similar to urllib.urlencode except that: * It uses quote, and not quote_plus * It has a default list of safe chars that don't need to be encoded, which matches what AWS services expect. If any value in the input ``mapping`` is a list type, then each list element wil be serialized. This is the equivalent to ``urlencode``'s ``doseq=True`` argument. This function should be preferred over the stdlib ``urlencode()`` function. :param mapping: Either a dict to urlencode or a list of ``(key, value)`` pairs. �itemsz%s=%s�&)rD r� r: r� r[ �percent_encoder\ )�mapping�safeZ encoded_pairs�pairsr� rk �elementr/ r/ r3 �percent_encode_sequencen s � � r� c C s> t | tjtjf�s t�| �} t | tj�s2| �d�} t| |d�S )a� Urlencodes a string. Whereas percent_encode_sequence handles taking a dict/sequence and producing a percent encoded string, this function deals only with taking a string (not a dict/sequence) and percent encoding it. If given the binary type, will simply URL encode it. If given the text type, will produce the binary type by UTF-8 encoding the text.

This function can be used to normalize all timestamp inputs. This function accepts a number of different types of inputs, but will always return a datetime.datetime object with time zone information. The input param ``value`` can be one of several types: * A datetime object (both naive and aware) * An integer representing the epoch time (can also be a string of the integer, i.e '0', instead of 0). The epoch time is considered to be UTC. * An iso8601 formatted timestamp. This does not need to be a complete timestamp, it can contain just the date portion without the time component. The returned value will be a datetime object that will have tzinfo. If no timezone info was provided in the input value, then UTC is assumed, not local time.

This class contains a ``generate_skeleton`` method that will take an input/output shape (created from ``botocore.model``) and generate a sample dictionary corresponding to the input/output shape. The specific values used are place holder values. For strings either an empty string or the member name can be used, for numbers 0 or 0.0 is used. The intended usage of this class is to generate the *shape* of the input structure. This can be useful for operations that have complex input shapes. This allows a user to just fill in the necessary data instead of worrying about the specific structure of the input arguments. Example usage:: s = botocore.session.get_session() ddb = s.get_service_model('dynamodb') arg_gen = ArgumentGenerator() sample_input = arg_gen.generate_skeleton( ddb.operation_model('CreateTable').input_shape) print("Sample input for dynamodb.CreateTable: %s" % sample_input) Fc C s || _ d S ru )�_use_member_names)ry Zuse_member_namesr/ r/ r3 rz � s zArgumentGenerator.__init__c C s g }| � ||�S )z�Generate a sample input. :type shape: ``botocore.model.Shape`` :param shape: The input shape. :return: The generated skeleton input corresponding to the provided input shape. )�_generate_skeleton)ry rG �stackr/ r/ r3 �generate_skeleton� s z#ArgumentGenerator.generate_skeletonrI c C sF |� |j� �z(|jdkr0| �||�W |�� S |jdkrP| �||�W |�� S |jdkrp| �||�W |�� S |jdkr�| jr�|W |�� S |jr�t � |j�W |�� S W |�� dS |jdv r�W |�� dS |jdkr�W |�� d S |jd k�rW |�� d S |jd k�r,t � d ddddd�W |�� S W |�� n |�� 0 d S )NZ structurer� �maprC rI )�integer�longr r� g �booleanT� timestampr r$ ) r[ rO rF �_generate_type_structurerZ �_generate_type_list�_generate_type_mapr7 �enum�random�choicer� �ry rG r9 rO r/ r/ r3 r8 � sV � � � � � � � � � �z$ArgumentGenerator._generate_skeletonc C sF |� |j�dkri S t� }|j�� D ] \}}| j|||d�||< q$|S )Nr$ )rO )�countrO r �membersr� r8 )ry rG r9 Zskeleton� member_nameZ member_shaper/ r/ r3 r@ � s � z*ArgumentGenerator._generate_type_structurec C s$ d}| j r|jj}| �|j||�gS )NrI )r7 �memberrO r8 rF r/ r/ r3 rA � s �z%ArgumentGenerator._generate_type_listc C s0 |j }|j}|jdksJ �td| �||�fg�S )NrC ZKeyName)r� rk rF r r8 )ry rG r9 Z key_shapeZ value_shaper/ r/ r3 rB � s �z$ArgumentGenerator._generate_type_mapN)F)rI ) rp rq rr rs rz r: r8 r@ rA rB r/ r/ r/ r3 r6 s s r6 c C s t | �j}t�|�d uS ru )r �netloc� IPV6_ADDRZ_RE�match)� endpoint_urlrK r/ r/ r3 �is_valid_ipv6_endpoint_url� s rO c C sZ t | �}|j}|du rdS t|�dkr*dS |d dkrB|dd� }t�dtj�}|�|�S )z�Verify the endpoint_url is valid. :type endpoint_url: string :param endpoint_url: An endpoint_url.

This decorator is used to cache method calls. The cache is only scoped to a single instance though such that multiple instances will maintain their own cache. In order to keep things simple, this decorator requires that you provide an ``_instance_cache`` attribute on your instance. c sb �|f}|r&t t|�� ��}�||f}| j�|�}|d ur>|S � | g|�R i |��}|| j|< |S ru )�tuple�sortedr� Z_instance_cacherE )ry �argsr� � cache_keyZ kwarg_items�result��func� func_namer/ r3 � _cache_guard| s z$instance_cache.<locals>._cache_guard)rp � functools�wraps)rs ru r/ rr r3 �instance_cachek s rx c K sh t | j�j�d�}dd� |D �}d}t|�dkrB|d�|�d 7 }|d7 }|dv rVdS t| |d d � dS ) z?Switches the current s3 endpoint with an S3 Accelerate endpointrW c S s g | ]}|t v r|�qS r/ ��S3_ACCELERATE_WHITELIST�r1 �pr/ r/ r3 r4 � r5 z-switch_host_s3_accelerate.<locals>.<listcomp>zhttps://s3-accelerate.r � amazonaws.com)Z ListBuckets� CreateBucketZ DeleteBucketNF)�use_new_scheme)r r] rK rY rh r\ � _switch_hosts)rw Zoperation_namer� rT r� r/ r/ r3 �switch_host_s3_accelerate� s r� c C s2 t �| j�d��}|�|�r.|| }t| |� dS )zBSwitches the host using a parameter value from a JSON request bodyr� N)r r� �datar* rE r� )rw � param_nameZ request_json� new_endpointr/ r/ r3 �switch_host_with_param� s r� c C s t | j||�}|| _d S ru )�_get_new_endpointr] )rw r� r �final_endpointr/ r/ r3 r� � s �r� c C sR t |�}t | �}|j}|r |j}||j|j|jdf}t|�}t�d| |f � |S �NrI zUpdating URI from %s to %s)r rh rK rT ri r r� r� )Zoriginal_endpointr� r Znew_endpoint_componentsZ original_endpoint_componentsrh Zfinal_endpoint_componentsr� r/ r/ r3 r� � s ��r� c C sR |D ]H}|| v r@t | | t�r@t || t�r@t| | || � q|| | |< qdS )z�Deeply two dictionaries, overriding existing keys in the base. :param base: The base dictionary which will be merged into. :param extra: The dictionary to merge into the base.
