The post MariaDB Galera Cluster 10.0.22 and Connector updates appeared first on MariaDB.org.
Last week, a SSL connection security vulnerability was reported for MySQL and MariaDB. The vulnerability states that since MariaDB and MySQL do not enforce SSL when SSL support is enabled, it’s possible to launch Man In The Middle attacks (MITM). MITM attacks can capture the secure connection and turn it into an insecure one, revealing data going back and forth to the server.
Issue resolution in MariaDB is visible through the corresponding ticket in MariaDB’s tracking system (JIRA): https://mariadb.atlassian.net/browse/MDEV-7937
The vulnerability affects the client library of the database server in both MariaDB and MySQL. But, the vulnerability does not affect all the libraries, drivers or connectors for establishing SSL connections with the server.
The vulnerability exists when the connection to the server is done through the client …
[Read more]Following on the heels of last week’s update to the Java client, the MariaDB project is pleased to today announce updates to both MariaDB Connector/C and Connector/ODBC. They are both Stable (GA) releases.
See the Release Notes and Changelogs for detailed information on each of these releases and contain many bug fixes and enhancements.

[Read more]In this post, I’ll cover how to create a simple C/C++ program that interacts with MySQL using the C API (and Connector/C). I discussed in a previous post how to install the C Connector (both SkySQL and MySQL’s), so please refer to that if you are looking for more specifics on that.
So once you have that set up, then there are just a few more things you need to have in order – at least this was the case in my environment.
1. Create a program (this one simply connects to the server and retrieves the server version):
#include <stdio.h>
#include <windows.h>
#include <mysql.h>
MYSQL *conn;
int version = 1;
int main ( int argc, char *argv[] )
{
conn = mysql_init ( NULL );
mysql_real_connect ( conn, "localhost", "root",
"password", "test", 3308, NULL, 0 );
version = mysql_get_server_version( conn ); …[Read more]
I’m writing a post on how to create your first C/C++ program for MySQL (using Windows, and from the command line). A prerequisite for that is to have a C Connector, such as MySQL Connector/C or SkySQL C Connector, so the program can communicate with mysqld.
I didn’t want that post to be too scattered, so I decided to split it into two, more focused posts. That said, this first post will focus on the Connector, and the next post will actually cover the program itself.
Installing and using Connector/C with MySQL is quite simple, so I wanted to show how easy it is. I also wanted to show examples with both SkySQL C Connector with MariaDB (which also works with MySQL) and Connector/C with MySQL, since both are widely used. I also wanted to show some common errors one might encounter and their resolutions, so hopefully this will help anyone who might have issues …
