MySQL Connector/C++ 1.1.8 has been released

Dear MySQL Users,

A new GA (general availability) version of MySQL Connector/C++ has
been made available: MySQL Connector/C++ 1.1.8 GA. The MySQL
Connector/C++ provides a C++ API for connecting client applications to
the MySQL Server 5.5 or newer.

You can download the production release at:

http://dev.mysql.com/downloads/connector/cpp/1.1.html

MySQL Connector C++ (Commercial) will be available for download on the
My Oracle Support (MOS) website. This release will be available on eDelivery
(OSDC) in next month’s upload cycle.

The MySQL driver for C++ offers an easy to use API derived from JDBC
4.0. MySQL Workbench has used it successfully for years.

We have improved the driver since the last GA release. Please see the
documentation and the CHANGES file in the source distribution for a
detailed description of bugs that have been fixed. Bug descriptions are
also listed below.

Enjoy!

======================================================================

Changes in MySQL Connector/C++ 1.1.8 (2016-12-16, General
Availability)

Security Notes

* OpenSSL is ending support for version 1.0.1 in December
2016; see
https://www.openssl.org/policies/releasestrat.html.
Consequently, Connector/C++ Commercial builds now use
version 1.0.2 rather than version 1.0.1, and the linked
OpenSSL library for the Connector/C++ Commercial has been
updated from version 1.0.1 to version 1.0.2j. For a
description of issues fixed in this version, see
https://www.openssl.org/news/vulnerabilities.html.
This change does not affect Oracle-produced MySQL
Community builds of Connector/C++, which use the yaSSL
library instead.

Functionality Added or Changed

* Connector/C++ now supports a OPT_TLS_VERSION connection
option for specifying the protocols permitted for
encrypted connections. The option value is string
containing a comma-separated list of one or more protocol
names. Example:
connection_properties[“OPT_TLS_VERSION”] = sql::SQLString(“TLSv1.1,TLS
v1.2”);

The permitted values depend on the SSL library used to
compile MySQL: TLSv1, TLSv1.1, TLSv1.2 if OpenSSL was
used; TLSv1 and TLSv1.1 if yaSSL was used. The default is
to permit all available protocols.
For more information about connection protocols in MySQL,
see Secure Connection Protocols and Ciphers
(http://dev.mysql.com/doc/refman/5.7/en/secure-connection-protocols-ciphers.html). (Bug #23496967)

* Connector/C++ now supports a OPT_SSL_MODE connection
option for specifying the security state of the
connection to the server. Permitted option values are
SSL_MODE_PREFERRED (the default), SSL_MODE_DISABLED,
SSL_MODE_REQUIRED, SSL_MODE_VERIFY_CA, and
SSL_MODE_VERIFY_IDENTITY. These values correspond to the
values of the –ssl-mode option supported by MySQL client
programs; see Command Options for Secure Connections
(http://dev.mysql.com/doc/refman/5.7/en/secure-connection-options.html).
For example, this setting specifies that
the connection should be unencrypted:
connection_properties[“OPT_SSL_MODE”] = sql::SSL_MODE_DISABLED;

The OPT_SSL_MODE option comprises the capabilities of the
sslEnforce and sslVerify connection options.
Consequently, both of those options are now deprecated.
(Bug #23496952)

* Connector/C++ now supports OPT_MAX_ALLOWED_PACKET and
OPT_NET_BUFFER_LENGTH connection options. Each option
takes a numeric value. They correspond to the
MYSQL_OPT_MAX_ALLOWED_PACKET and
MYSQL_OPT_NET_BUFFER_LENGTH options for the
mysql_options() C API function.

* Issues compiling Connector/C++ under Visual Studio 2015
were corrected.

Bugs Fixed

* A segmentation fault could occur for attempts to insert a
large string using a prepared statement. (Bug #23212333,
Bug #81213)

* The certification verification checks that are enabled by
the verifySSL connection option were not performed
properly. (Bug #22931974)

* Connector/C++ failed to compile against a version of the
MySQL C API older than 5.7. (Bug #22838573, Bug #80539,
Bug #25201287)

MySQL Connector/C++ 2.0.3 m3 Development Release has been released

MySQL Connector/C++ 2.0.3 is the next development milestone of the MySQL Connector/C++ 2.0 series, and the first public release. Apart from covering more X DevAPI features, it adds a new, plain C API, called XAPI, that offers functionality similar to X DevAPI to applications written in plain C. Thus, not only can MySQL Connector/C++ be used to write C++ applications, as before.

Now, using the XAPI, MySQL Connector/C++ can be used to write plain C applications to access MySQL Database implementing a document store as well as execute traditional plain SQL statements. For more information about XAPI, refer to the documentation at http://dev.mysql.com/doc/dev/connector-cpp/xapi_ref.html.

To learn more about how to write applications using the X DevAPI, see X DevAPI User Guide (http://dev.mysql.com/doc/x-devapi-userguide/en/). For more information about how to use Connector/C++ 2.0 and how the X DevAPI is implemented in it, see http://dev.mysql.com/doc/dev/connector-cpp/.

Note

The X DevAPI requires at least MySQL Server version 5.7.12 or higher with the X Plugin enabled. For general documentation about how to get started using MySQL as a document store, see Using MySQL as a Document Store (http://dev.mysql.com/doc/refman/5.7/en/document-store.html).

To download MySQL Connector/C++ 2.0.3 m3, see the “Development Releases” tab at http://dev.mysql.com/downloads/connector/cpp/

X DevAPI Notes

New X DevAPI features added in this MySQL Connector/C++ release:

  • Methods for starting and controlling transactions
  • Using an X DevAPI URI or connection string to specify new session parameters
  • Capability of binding a session to the default shard and execute SQL statements there (using XSession.bindToDefaultShard())
  • Methods for counting elements in a table or collection
  • Access to multiple result sets if present in a query result
  • Methods to count items in a result set and fetch a complete result set at once (using fetchAll()), instead of accessing items one by one (using fetchOne())
  • Access to warnings reported when processing a statement (getWarnings())
  • Access to information about affected rows, generated auto-increment values, and identifiers of documents added to a collection
