Hi !

First of all, congratulations to MariaDB 10.2 GA.

mysqlclient (python binding : https://pypi.python.org/pypi/mysqlclient/1.3.10 ) cannot be built with MariaDB 10.2.6 like the following :

_mysql.c: In function '_mysql_ConnectionObject_ping': _mysql.c:1911:41: error: 'MYSQL' has no member named 'reconnect' if ( reconnect != -1 ) self->connection.reconnect = reconnect;

Thanks. This is now reported as https://jira.mariadb.org/browse/MDEV-12950

error: Setup script exited with error: command 'gcc' failed with exit status 1

This is because the change in include/mysql/mysql.h.

In MariaDB 10.2.5, it is same as mariadb-10.2.5/include/mysql.h in the source tree. In MariaDB 10.2.6, it is same as mariadb-10.2.6/libmariadb/include/mysql.h in the source tree.

Is this change intentional ? Should I contact mysqlclient developer for further fix of this issue ?

Yes, it was intentional, one is supposed to use mysql_options(mysql, MYSQL_OPT_RECONNECT, ...); this works both in libmysqlclient and in the new libmariadb and doesn't depend on the internal MYSQL structure. The effect of breaking python connector (and perl DBD-mysql) was unintentional, though. At the moment I don't know what the fix will be - e.g. we could temporarily restore mysql->reconnect. Or we could submit patches to python and perl connectors to use MYSQL_OPT_RECONNECT. Or both. Or something else. Regards, Sergei Chief Architect MariaDB and security@mariadb.org
