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 C s t �| �}|rt|�d��S dS )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�m� r �I/usr/local/CyberPanel/lib/python3.10/site-packages/MySQLdb/connections.py� numeric_part# s r c s� e Zd ZdZejZ� fdd�Z d!dd�Zd d � Z d d � Z d d� Z d"dd�Z dd� Z dd� Zdd� Zdd� Zdd� Zd"� fdd � Zd d � Zd d � ZeZeZeZeZeZeZeZe Z e Z e Z � Z S )#� Connectionz MySQL Database Connection Objectc sJ ddl m}m} ddlm}m} |�� }d|v r |�d�|d< d|v r*|�d�|d< d|v r3|d }n|}i } |�� D ]\} } t | t �rRt | t �rR| d d � | | < q;| | | < q;| |d< |�d | j �} |� d d �} |�d d �}|�dd�}|�dd �}|�dd�| _|� dd�}||jO }|�dd�}|r�||jO }||d< |�dd�}| j|i |�� t� j|i |�� | | _dd� |�� D �| _tdd� | �� �d�d d� D ��| _d | _| s�| �� } | � | |� |r�| � |� |�r |j |j |j |j!|j"|j#|j$fD ]}|| j%|< q�t&| j%|j'< | j(|j)@ | _*| j*�r |d u�r | �+|� g | _,d S ) 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� autocommitc S s" i | ] \}}t |�tur||�qS r )�typer )�.0�k�vr r r � <dictcomp>� s �z'Connection.__init__.<locals>.<dictcomp>c S s g | ]}t |��qS r )r )r6 �nr r r � <listcomp>� s z'Connection.__init__.<locals>.<listcomp>�.� �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+ �encoders�tuple�get_server_info�split�_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�_transactionalr4 �messages)�self�args�kwargsr" r# r$ r% �kwargs2r* �conv2r7 r8 r+ r, r. r/ r0 r2 r3 r4 �t�� __class__r r rM 8 sx g � � � zConnection.__init__Nr- �� c K s( |r|sd}|| _ || _|| _|| _dS )z set some attributes for otel� localhostN)�host�userr' r& )re ro rp r) r' �port� unix_socketrg r r r rK � s zConnection._set_attributesc C s | S �Nr �re r r r � __enter__ s zConnection.__enter__c C s | � � d S rs )�close)re �exc_type� exc_value� tracebackr r r �__exit__ s zConnection.__exit__c C s* t |�}| �� |krtj�| |� d S d S rs )�bool�get_autocommitr � connectionr4 )re �onr r r r4 s �zConnection.autocommitc C s |p| j | �S )z� Create a cursor on which queries may be performed.
