Regarding the crash described earlier:
I looked at the file driver.c in your repository
https://github.com/tarantool/mysql/blob/master/mysql/driver.c
line 316 which looks like this:
"
mysql_real_connect(mysql, host, user, password, db, iport, usocket,
CLIENT_MULTI_STATEMENTS | CLIENT_MULTI_RESULTS);
"
I changed it to this:
"
mysql_init(mysql);
mysql_real_connect(mysql, host, user, password, db, iport, usocket,
CLIENT_MULTI_STATEMENTS | CLIENT_MULTI_RESULTS);

coio_call() uses random threads for each call. mysql_init() is only called once in the first thread.
Probably we should use the single thread for all mysql operations.

Already fixed.
