Presently there is only one class: Connection. Others are unlikely. However, you might want to make your own subclasses. In most cases, you will probably override Connection.default_cursor with a non-standard Cursor class. � N� )�cursors�_mysql) �Warning�Error�InterfaceError� DataError� DatabaseError�OperationalError�IntegrityError� InternalError�NotSupportedError�ProgrammingError�utf8�cp1252�koi8_r�koi8_u)�utf8mb4�utf8mb3�latin1�koi8r�koi8uz^(\d+)c �f � t j | � }|rt |j d� � S y)z�Returns the leading numeric part of a string. >>> numeric_part("20-alpha") 20 >>> numeric_part("foo") >>> numeric_part("16b") 16 r N)�re_numeric_part�match�int�group)�s�ms �D/opt/hc_python/lib64/python3.12/site-packages/MySQLdb/connections.py� numeric_partr! # s, � � � � �a� �A���1�7�7�1�:�� � � c � � � e Zd ZdZej Z� fd�Z dd�Zd� Z d� Z d� Z dd�Z d� Z d � Zd � Zd � Zd � Zd� fd � Zd� Zd� ZeZeZeZeZeZeZeZe Z e Z e Z � xZ S )� Connectionz MySQL Database Connection Objectc �t �� ddl m}m} ddlm}m} |j � }d|v r|j d� |d< d|v r|j d� |d< d|v r|d }n|}i } |j � D ]3 \ } } t | t � rt | t � r | d d | | < �/| | | < �5 | |d< |j d | j � } |j d d � } |j d d � }|j dd� }|j dd � }|j dd� | _ |j dd� }||j z }|j dd� }|r||j z }||d< |j dd� } | j" |i |�� t% �| �L |i |�� | | _ |j � D � � ci c] \ } } t+ | � t ur| | �� c} } | _ t/ | j1 � j3 d� d d D �cg c] }t5 |� �� c}� | _ d| _ | s| j; � } | j= | |� |r| j? |� |r�|j@ |jB |jD |jF |jH |jJ |jL fD ] }|| jN |< � tP | jN |jR < | jT |jV z | _, | jX r|�| j[ |� g | _. y c c} } w c c}w )aZ Create a connection to the database. It is strongly recommended that you only use keyword parameters. Consult the MySQL C API documentation for more information. :param str host: host to connect :param str user: user to connect as :param str password: password to use :param str passwd: alias of password (deprecated) :param str database: database to use :param str db: alias of database (deprecated) :param int port: TCP/IP port to connect to :param str unix_socket: location of unix_socket to use :param dict conv: conversion dictionary, see MySQLdb.converters :param int connect_timeout: number of seconds to wait before the connection attempt fails. :param bool compress: if set, compression is enabled :param str named_pipe: if set, a named pipe is used to connect (Windows only) :param str init_command: command which is run once the connection is created :param str read_default_file: file from which default client values are read :param str read_default_group: configuration group to use from the default file :param type cursorclass: class object, used to create cursors (keyword only) :param bool use_unicode: If True, text-like columns are returned as unicode objects using the connection's character set. Otherwise, text-like columns are returned as bytes. Unicode objects will always be encoded to the connection's character set regardless of this setting. Default to True. :param str charset: If supplied, the connection character set will be changed to this character set. :param str collation: If ``charset`` and ``collation`` are both supplied, the character set and collation for the current connection will be set. If omitted, empty string, or None, the default collation for the ``charset`` is implied. :param str auth_plugin: If supplied, the connection default authentication plugin will be changed to this value. Example values: `mysql_native_password` or `caching_sha2_password` :param str sql_mode: If supplied, the session SQL mode will be changed to this setting. For more details and legal values, see the MySQL documentation. :param int client_flag: flags to use or 0 (see MySQL docs or constants/CLIENTS.py) :param bool multi_statements: If True, enable multi statements for clients >= 4.1. Defaults to True. :param str ssl_mode: specify the security settings for connection to the server; see the MySQL documentation for more details (mysql_option(), MYSQL_OPT_SSL_MODE). Only one of 'DISABLED', 'PREFERRED', 'REQUIRED', 'VERIFY_CA', 'VERIFY_IDENTITY' can be specified. :param dict ssl: dictionary or mapping contains SSL connection parameters; see the MySQL documentation for more details (mysql_ssl_set()). If this is set, and the client does not support SSL, NotSupportedError will be raised. Since mysqlclient 2.2.4, ssl=True is alias of ssl_mode=REQUIRED for better compatibility with PyMySQL and MariaDB. :param str server_public_key_path: specify the path to a file RSA public key file for caching_sha2_password. See https://dev.mysql.com/doc/refman/9.0/en/caching-sha2-pluggable-authentication.html :param bool local_infile: enables LOAD LOCAL INFILE; zero disables :param bool autocommit: If False (default), autocommit is disabled. If True, autocommit is enabled. If None, autocommit isn't set and server default is used. :param bool binary_prefix: If set, the '_binary' prefix will be used for raw byte query arguments (e.g. Binary). This is disabled by default. There are a number of undocumented, non-standard methods. See the documentation for the MySQL C API for some hints on what they do. r )�CLIENT� FIELD_TYPE)� conversions� _bytes_or_str�db�database�passwd�password�convN� cursorclass�charset� � collation� use_unicodeT�sql_mode� binary_prefixF� client_flag�multi_statements� autocommit�.� �ascii)/�MySQLdb.constantsr& r' �MySQLdb.convertersr( r) �copy�pop�items� isinstancer �list�default_cursor�get�_binary_prefix� MULTI_RESULTS�MULTI_STATEMENTS�_set_attributes�super�__init__r/ �type�encoders�tuple�get_server_info�splitr! �_server_version�encoding�character_set_name�set_character_set� set_sql_mode�STRING� VAR_STRING�VARCHAR� TINY_BLOB� MEDIUM_BLOB� LONG_BLOB�BLOB� converter�str�JSON�server_capabilities� TRANSACTIONS�_transactionalr8 �messages)�self�args�kwargsr& r' r( r) �kwargs2r. �conv2�k�vr/ r0 r2 r3 r4 r6 r7 r8 �n�t� __class__s �r rJ zConnection.__init__8 s �� �N 9�A��+�+�-�� �7�?�")�+�+�d�"3�G�J� � �w� �")�+�+�h�"7�G�J� � �V� ��&�>�D� �D����J�J�L�D�A�q��!�S�!�j��D�&9� �Q�4��a�� ��a�� !� ���� �k�k�-��1D�1D�E� ��+�+�i��,���K�K� �R�0� � �k�k�-��6� ��;�;�z�2�.�� %�k�k�/�5� A��� �j�j� ��2� ��v�+�+�+� �"�;�;�'9�4�@�� � �6�2�2� 2�K�!,�� � � �[�[� �u�5� � �� � �d�.�g�.� ���$�*�'�*�&��� � � � � �$���1��A�w�c�!� �q�D�$� �� � %�&*�&:�&:�&<�&B�&B�3�&G���&K� L�&K��\�!�_�&K� L� �� � �� ���-�-�/�G� � � �w� �2� � � � �h� '� ��!�!��%�%��"�"��$�$��&�&��$�$������ %2����q�!�� /2�D�N�N�:�?�?� +� "� 6� 6��9L�9L� L��� � � ��%���� �+��� ��I �� Ms �< L/� L5c �H � |r|sd}|| _ || _ || _ || _ y)z set some attributes for otel� localhostN)�host�userr+ r* )rc ro rp r- r+ �port� unix_socketre s r rH zConnection._set_attributes� s* � � �t� �D��� ��� � �� ���r" c � � | S �N� �rc s r � __enter__zConnection.__enter__ s � �� r" c �$ � | j � y rt )�close)rc �exc_type� exc_value� tracebacks r �__exit__zConnection.__exit__ s � � � � � r" c � � t |� }| j � |k7 r!t j j | |� y y rt )�bool�get_autocommitr � connectionr8 )rc �ons r r8 zConnection.autocommit s7 � � �"�X�� � � � �B� &� � � � (� (��r� 2� 'r" c �. � |xs | j | � S )z� Create a cursor on which queries may be performed.
