This is a Stable (GA) release of the MariaDB Connector/C, formerly known as MariaDB Client Library for C.

For a description of this library see theMariaDB Connector/C page.

Features

• Added option MYSQL_OPT_CAN_HANDLE_EXPIRED_PASSWORDS for mysql_options()/mysql_optionsv():If this option is set, client indicates that it will be able to handle expired passwords by setting the CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS capability flag. If password is expired and CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS is set, the server will not return an error when connecting, but will put the connection in sandbox mode, where all commands will return error 1820/1828 (ER_MUST_CHANGE_PASSWORD/ER_MUST_CHANGE_PASSWORD_LOGIN) unless a new password was set.

• New plugin configuration interface: The default configuration for a specific plugin can be specified via cmake parameter -DCLIENT_PLUGIN_${PLUGIN}=[DYNAMIC|STATIC|OFF].

• Added support for linux abstract socket (MDEV-15655). Thanks to Daniel Black for his contribution.

• Added Travis and Appveyor build support

• CONC-320: Added asynchronous/non-blocking support for OpenSSL and GnuTLS

Notable Bug fixes

• Fixed various clang compiler warnings

• CONC-294: Access violation in mysql_close when using a connection plugin.

• MDEV-14977: If built dynamically the old_password plugin could not be located due to wrong filename (must be mysql_old_password.so instead of old_password.so).

• CONC-315: If no default client character set was specified, the utf8 character set will be used by default (instead of setting the client character set to server character set)

• CONC-317: Parsing of configuration file fails if key/value pairs contain white spaces.

• CONC-322: Correct handling of EAGAIN and EINPROGRESS in internal_connect (socket) for non windows platforms.

• CONC-323: mariadb_stmt_execute_direct hangs forever if compression used.

• CONC-324: Wrong codepage numbers for some collations.

• CONC-326: ssl_thread_init() uses wrong openssl threadid callback
