Dear MySQL users,
MySQL Connector/C 6.1.2, a new version of the C API for client/server
communication for the MySQL database management system, has been
This version of Connector/C provides full support for MySQL 5.6
protocol. Connector/C is compatible with the client libraries
(libmysql). It includes all the features in the MySQL client library
shipped with MySQL servers 5.6 as well as prior versions. You can
recompile existing code linked with Connector/C 6.1.2 without any code
You can use Connector/C to run and build client applications which
communicate with MySQL server versions from 4.1 to 5.6 without a need
to do a complete server installation.
The release is now available in source and binary form for a number
of platforms from our download pages at
MySQL Connector/C 6.1.2 will also be available for downloads via the
Oracle Software Delivery Cloud in approximately 1-2 weeks.
For information on installing, please see the documentation at
The MySQL build team at Oracle
Functionality Added or Changed
* The implementation of condition variables specific to Windows
XP and Windows Server 2003 was removed from the source code
because MySQL is not supported on those platforms as of MySQL
This change has the following implication: Previously,
Connector/C 6.1, while not officially supported on Windows XP
or Windows Server 2003, could be used on those platforms. This
is no longer possible.
* MySQL now supports the use of client-side plugins that
implement tracing of communication between a client and the
server that takes place using the client/server protocol.
Protocol trace plugins use the client plugin API (see Writing
In Connector/C source distributions, a test protocol trace
plugin is implemented in the test_trace_plugin.cc file in the
libmysql directory. This can be examined as a guide to writing
other protocol trace plugins.
* Static libraries built with VS2008, VS2010, VS2012 are now
distributed as part of Connector/C packages for Windows: ZIP
and MSI. New directories named vs9, vs10, and vs11 located
under the lib directory contain static libraries and
corresponding pdb files built with VS2008, VS2010, and VS2012,
* The CLIENT_CONNECT_WITH_DB flag was improperly handled in the
C client library. This could lead to a malformed packet sent
to the server. (Bug #17351732)
* The mysql_real_connect() C API function could leak memory if
it failed. (Bug #17337684)
* The mysql_options() C API function could leak memory if called
more than once with the MYSQL_SET_CLIENT_IP option.
* The Connector/C MSI package was missing the following files:
ChangeLog, README, LICENSE, COPYING, INFO_SRC, INFO_BIN.
* The Connector/C RPM package was missing the following files:
INFO_SRC, INFO_BIN, my_print_defaults, perror. (Bug #17261610)
* On Windows, a MySQL client program that simply used #include
<mysql.h> could not be compiled due to missing Windows
declarations in that file. The same program would compile on
other platforms. (Bug #16409270)
* The libmysql.dll library was missing several symbols: my_init,
mysql_load_plugin, mysql_load_plugin_v, and
mysql_plugin_options. (Bug #69204, Bug #16797982)
