Deprecated Python 2.7 support; a warning was added to describe Python 2.7 support being removed in Connector/Python 8.0.24.
Previously, Connector/Python added client support for the MySQL Enterprise Edition SASL LDAP authentication plugin with SCRAM-SHA-1 as an authentication method. Connector/Python now also supports SCRAM-SHA-256 as an alternative authentication method for classic MySQL protocol connections. SASL-based LDAP authentication does not apply to clients running macOS.
Added SASL authentication protocol support using the GSSAPI (Kerberos) authentication method for the pure python implementation (this is not available for the c-ext version of Connector/Python).
This functionality requires the GSSAPI pypi module, which provides both low-level and high-level wrappers around the GSSAPI C libraries. The GSSAPI pypi module requires MIT kerberos installed opn the system to function and request tickets to authenticate Connector/Python with the MySQL server when the user is IDENTIFIED WITH authentication_ldap_sasl and the authentication_ldap_sasl plugin is configured to use the GSSAPI mechanism.
This also adds a new
krb_service_principaloption, which must be a string in the form "primary/instance@realm" such as "ldap/ldapauth@MYSQL.COM" where "@realm" is optional. The "@realm" defaults to the default realm, as configured in the
Removed the MySQL client-plugins dependency, although it's recommended. This plugin allows MySQL to use its newer authentication methods, thus it's required for connecting to accounts using the new authentication methods such as
caching_sha2_password. (Bug #32114921, Bug #101464)
Fixed the AttributeError raised when getting the connection ID from a closed CMySQLConnection. (Bug #31882419, Bug #100825)
Fixed support for named tuple (an invalid exception was generated) and dictionary cursors (incorrect type of result was returned). (Bug #29195610)
Fixed cursor.fetchone() and cursor.fetchmany() to comply with PEP 249, which specifies that an exception must be raised if the previous call to cursor.execute*() does not produce any result set or no call was issued yet. (Bug #26834307, Bug #87815)
Fixed the microsecond conversion from MySQL datetime to Python datetime when using fractional values with the C extension enabled. For example, 2016-10-20 15:40:23.8 from MySQL resulted in datetime.datetime(2016, 10, 20, 15, 40, 23, 8) instead of datetime.datetime(2016, 10, 20, 15, 40, 23, 800000). Thanks to Vilnis Termanis for the patch. (Bug #24938411, Bug #31556777, Bug #83479, Bug #100034)
Updated associated MySQL server error messages and codes to the latest version. (Bug #102220, Bug #32370045)
