The URL object is created automatically when :func:`~sqlalchemy.engine.create_engine` is called with a string argument; alternatively, the URL is a public-facing construct which can be used directly and is also accepted directly by ``create_engine()``. � )� annotationsN)�Any)�cast)�Dict)�Iterable)�List)�Mapping)� NamedTuple)�Optional)�overload)�Sequence)�Tuple)�Type)�Union)� parse_qsl)�quote)� quote_plus)�unquote� )�Dialect� )�exc)�util)�plugins)�registryc �f � e Zd ZU dZded< ded< ded< ded< ded < ded < d ed < ed d d d d ej f d*d�� Zed+d�� Z ed,d�� Z e d-d�� Z e d.d�� Z d/ d0d�Z d1d�Z d2 d3d�Z d2 d4d�Z d2 d5d�Zd6d�Zed7d�� Z ej* dd� d8d9d �� Zd8d9d �Zd:d �Zd;d �Zd<d �Zd=d!�Zd>d"�Z d>d#�Z d:d$�Z d:d%�Z d?d&�Z d@d'�Z!d2dAd(�Z" dB dCd)�Z#y )D�URLa� Represent the components of a URL used to connect to a database. URLs are typically constructed from a fully formatted URL string, where the :func:`.make_url` function is used internally by the :func:`_sa.create_engine` function in order to parse the URL string into its individual components, which are then used to construct a new :class:`.URL` object. When parsing from a formatted URL string, the parsing format generally follows `RFC-1738 <https://www.ietf.org/rfc/rfc1738.txt>`_, with some exceptions. A :class:`_engine.URL` object may also be produced directly, either by using the :func:`.make_url` function with a fully formed URL string, or by using the :meth:`_engine.URL.create` constructor in order to construct a :class:`_engine.URL` programmatically given individual fields. The resulting :class:`.URL` object may be passed directly to :func:`_sa.create_engine` in place of a string argument, which will bypass the usage of :func:`.make_url` within the engine's creation process. .. versionchanged:: 1.4 The :class:`_engine.URL` object is now an immutable object. To create a URL, use the :func:`_engine.make_url` or :meth:`_engine.URL.create` function / method. To modify a :class:`_engine.URL`, use methods like :meth:`_engine.URL.set` and :meth:`_engine.URL.update_query_dict` to return a new :class:`_engine.URL` object with modifications. See notes for this change at :ref:`change_5526`. .. seealso:: :ref:`database_urls` :class:`_engine.URL` contains the following attributes: * :attr:`_engine.URL.drivername`: database backend and driver name, such as ``postgresql+psycopg2`` * :attr:`_engine.URL.username`: username string * :attr:`_engine.URL.password`: password string * :attr:`_engine.URL.host`: string hostname * :attr:`_engine.URL.port`: integer port number * :attr:`_engine.URL.database`: string database name * :attr:`_engine.URL.query`: an immutable mapping representing the query string. contains strings for keys and either strings or tuples of strings for values. �str� drivername� Optional[str]�username�password�host� Optional[int]�port�database�4util.immutabledict[str, Union[Tuple[str, ...], str]]�queryNc �� � | | j |d� | j |d� || j |d� | j |� | j |d� | j |� � S )a� Create a new :class:`_engine.URL` object. .. seealso:: :ref:`database_urls` :param drivername: the name of the database backend. This name will correspond to a module in sqlalchemy/databases or a third party plug-in. :param username: The user name. :param password: database password. Is typically a string, but may also be an object that can be stringified with ``str()``. .. note:: The password string should **not** be URL encoded when passed as an argument to :meth:`_engine.URL.create`; the string should contain the password characters exactly as they would be typed. .. note:: A password-producing object will be stringified only **once** per :class:`_engine.Engine` object. For dynamic password generation per connect, see :ref:`engines_dynamic_tokens`. :param host: The name of the host. :param port: The port number. :param database: The database name. :param query: A dictionary of string keys to string values to be passed to the dialect and/or the DBAPI upon connect. To specify non-string parameters to a Python DBAPI directly, use the :paramref:`_sa.create_engine.connect_args` parameter to :func:`_sa.create_engine`. See also :attr:`_engine.URL.normalized_query` for a dictionary that is consistently string->list of string. :return: new :class:`_engine.URL` object. .. versionadded:: 1.4 The :class:`_engine.URL` object is now an **immutable named tuple**. In addition, the ``query`` dictionary is also immutable. To create a URL, use the :func:`_engine.url.make_url` or :meth:`_engine.URL.create` function/ method. To modify a :class:`_engine.URL`, use the :meth:`_engine.URL.set` and :meth:`_engine.URL.update_query` methods. r r! r# r& )� _assert_str�_assert_none_str� _assert_port� _str_dict)�clsr r! r" r# r% r& r( s �F/opt/hc_python/lib64/python3.12/site-packages/sqlalchemy/engine/url.py�createz URL.create� sm � �p � �O�O�J� � 5� � � ��:� 6� � � � ��v� .� � � �T� "� � � ��:� 6� �M�M�%� � � � c �P � |�y t |� S # t $ r t d� �w xY w)Nz(Port argument must be an integer or None)�int� TypeError)r. r% s r/ r, zURL._assert_port� s7 � � �<�� H��t�9� ��� H�� F�G� G� H�s � �%c �B � t |t � st d|z � �|S )Nz%s must be a string�� isinstancer r4 �r. �v� paramnames r/ r* zURL._assert_str� s" � ��!�S�!�� 1�I� =�>� >��r1 c �. � |�|S | j ||� S �N)r* r8 s r/ r+ zURL._assert_none_str� s � � �9��H����q�)�,�,r1 c �X �� |�t j S t dd�� �t dd�� � d�fd� �dd�}t |t j � r|}n|j � }t j |D ��ci c] \ }} ||� �|� �� c}}� S c c}}w ) Nc � � y r< � ��vals r/ � _assert_valuez$URL._str_dict.<locals>._assert_value� s � � r1 c � � y r< r? r@ s r/ rB z$URL._str_dict.<locals>._assert_value s � � +.r1 c � �� t | t � r| S t | t j � rt �fd�| D � � S t d� �)Nc 3 �. �K � | ] } �|� �� � y �wr< r? )�.0�elemrB s �r/ � <genexpr>z7URL._str_dict.<locals>._assert_value.<locals>.<genexpr> s �� �� � A�S�T�]�4� 0�S�s �z?Query dictionary values must be strings or sequences of strings)r7 r �collections_abcr �tupler4 )rA rB s �r/ rB z$URL._str_dict.<locals>._assert_value sG �� � �#�s�#�� ��C� �!9�!9�:� � A�S� A�A�A� �+�� r1 c �< � t | t � s t d� �| S )Nz%Query dictionary keys must be stringsr6 )r9 s r/ r* z"URL._str_dict.<locals>._assert_str s � � �a��%� � G�H�H��Hr1 )rA r �returnr )rA z Sequence[str]rL �Union[str, Tuple[str, ...]])rA zUnion[str, Sequence[str]]rL rM )r9 r rL r )r � EMPTY_DICTr r7 rI r �items� immutabledict)r. �dict_r* � dict_items�key�valuerB s @r/ r- z URL._str_dict� s� �� � �=��?�?� "� � �� � � � � � � .� � .� (� .� � .� �*� � (� � � �e�_� 5� 5� 6� �J� ��� �J��!�!� #-� � #-�J�C�� �C� �-��#� � #-� � � �� s �B& c � � i }|�||d< |�||d< |�||d< |�||d< |�||d< |�||d< |�||d< | j di |��S ) a return a new :class:`_engine.URL` object with modifications.
