This module implements connections for MySQLdb. 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.

If cursor is not None, (errorclass, errorvalue) is appended to
cursor.messages; otherwise it is appended to
connection.messages. Then errorclass is raised with errorvalue as
the value.
You can override this with your own error handler by assigning it
to the instance.

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, for backward compatibility
:param str database: database to use
:param str db: alias of database, for backward compatibility
: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 str 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 strings. columns are returned as
normal strings. Unicode objects will always be encoded to
the connection's character set regardless of this setting.
Default to False on Python 2 and True on Python 3.
:param str charset:
If supplied, the connection character set will be changed
to this character set (MySQL-4.1 and newer). This implies
use_unicode=True.
:param str sql_mode:
If supplied, the session SQL mode will be changed to this
setting (MySQL-4.1 and newer). 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 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.
: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.
