By using this method, you can override the normal lookup process used in ``get_config_variable`` by explicitly setting a value. Subsequent calls to ``get_config_variable`` will use the ``value``. This gives you per-session specific configuration values. :: >>> # Assume logical name 'foo' maps to env var 'FOO' >>> os.environ['FOO'] = 'myvalue' >>> s.get_config_variable('foo') 'myvalue' >>> s.set_config_variable('foo', 'othervalue') >>> s.get_config_variable('foo') 'othervalue' :type logical_name: str :param logical_name: The logical name of the session variable you want to set.

The configuration data is loaded **only** from the config file. It does not resolve variables based on different locations (e.g. first from the session instance, then from environment variables, then from the config file). If you want this lookup behavior, use the ``get_config_variable`` method instead. Note that this configuration is specific to a single profile (the ``profile`` session variable). If the ``profile`` session variable is set and the profile does not exist in the config file, a ``ProfileNotFound`` exception will be raised. :raises: ConfigNotFound, ConfigParseError, ProfileNotFound :rtype: dict r!

You can use the ``Session.get_available_services()`` method to get a list of all available service names. :type region_name: string :param region_name: The name of the region associated with the client. A client is associated with a single region. :type api_version: string :param api_version: The API version to use. By default, botocore will use the latest API version when creating a client. You only need to specify this parameter if you want to use a previous API version of the client. :type use_ssl: boolean :param use_ssl: Whether or not to use SSL. By default, SSL is used. Note that not all services support non-ssl connections. :type verify: boolean/string :param verify: Whether or not to verify SSL certificates. By default SSL certificates are verified. You can provide the following values: * False - do not validate SSL certificates. SSL will still be used (unless use_ssl is False), but SSL certificates will not be verified. * path/to/cert/bundle.pem - A filename of the CA cert bundle to uses. You can specify this argument if you want to use a different CA cert bundle than the one used by botocore. :type endpoint_url: string :param endpoint_url: The complete URL to use for the constructed client. Normally, botocore will automatically construct the appropriate URL to use when communicating with a service. You can specify a complete URL (including the "http/https" scheme) to override this behavior. If this value is provided, then ``use_ssl`` is ignored. :type aws_access_key_id: string :param aws_access_key_id: The access key to use when creating the client. This is entirely optional, and if not provided, the credentials configured for the session will automatically be used. You only need to provide this argument if you want to override the credentials used for this specific client. :type aws_secret_access_key: string :param aws_secret_access_key: The secret key to use when creating the client. Same semantics as aws_access_key_id above. :type aws_session_token: string :param aws_session_token: The session token to use when creating the client. Same semantics as aws_access_key_id above. :type config: botocore.client.Config :param config: Advanced client configuration options. If a value is specified in the client config, its value will take precedence over environment variables and configuration values, but not over a value passed explicitly to the method. If a default config object is set on the session, the config object used when creating the client will be the result of calling ``merge()`` on the default config with the config provided to this call. :rtype: botocore.client.BaseClient :return: A botocore client instance N� ca_bundle� api_versionsrT rI r` )r� r� r� �explicit)�provider�cred_varr^ ra rq ) r� rP � is_secure� endpoint_url�verifyrR � scoped_configr� r� rs )r� �merge�_resolve_region_namerV r� rZ �signature_versionr rQ rR r� �_missing_cred_varsr r� r �client� ClientCreatorr� r r � create_clientr� re �metarj )r7 r� rP r� �use_sslr r �aws_access_key_id�aws_secret_access_key�aws_session_tokenr� �default_client_configr\ rI r` rR r^ ra rq �client_creatorr rs r; r; r< r � sj I � ����� �� zSession.create_clientc C s: |d u r|r|j d ur|j }n| �d�}t|� || _|S )N�region)rP rV r r. )r7 rP r� r; r; r< r S s z Session._resolve_region_namec C s, |d ur |d u r dS |d ur|d u rdS d S )Nr r r; )r7 r� r� r; r; r< r i s zSession._missing_cred_varsc C s | � d�}|�� S )z�Lists the available partitions found on disk :rtype: list :return: Returns a list of partition names (e.g., ["aws", "aws-cn"]) r^ )r �get_available_partitions)r7 �resolverr; r; r< r# p s z Session.get_available_partitionsc C s | � d�}|�|�S )a Lists the partition name of a particular region. :type region_name: string :param region_name: Name of the region to list partition for (e.g., us-east-1). :rtype: string :return: Returns the respective partition name (e.g., aws). r^ )r �get_partition_for_region)r7 rP r$ r; r; r< r% y s z Session.get_partition_for_region�awsc C sR | � d�}g }z| �|�}|d �d|�}|�|||�}W |S ty( Y |S w )a] Lists the region and endpoint names of a particular partition. :type service_name: string :param service_name: Name of a service to list endpoint for (e.g., s3).

This class can be used instead of :class:`botocore.configprovider.ConfigChainFactory` to make it honor the methods argument to get_config_variable.

This config chain factory will omit any providers not in the methods tuple provided at initialization. For example if given the tuple ('instance', 'config',) it will not inject the environment provider into the standard config chain. This lets the botocore session support the custom ``methods`` argument for all the default botocore config variables when calling ``get_config_variable``. r� Nr� r� rH )rM rL r� )r7 r� r� r� r� r� r; r; r< r� s �z,SubsetChainConfigFactory.create_config_chainr> )NNNNN)r/ r0 r1 r2 r= r� r; r; r; r< r� � s �r� c C s t | �S )z& Return a new session object. )r )r� r; r; r< � get_session s rN r> ):r2 r� r� r� r� ry r rQ r r �botocore.configloader�botocore.credentials�botocore.client�botocore.configproviderr r r r �botocore.exceptionsr r r r �botocore.errorfactoryr r �botocore.hooksr r r �botocore.loadersr �botocore.parsersr �botocore.regionsr �botocore.modelr r r r r r �botocore.utilsr r �botocore.compatr r r� r/ r� �objectr r/ r3 r� rN r; r; r; r< �<module> sV s"-(
