When called as follows, the mariadb-1.1.8 connector has a memory lead due to leaking connection and cursor objects:

with mariadb.Connection( host='localhost',  user='root', password=db_pass, unix_socket=db_sock, connect_timeout=5 ) as db_conn:

    my_cur = db_conn.cursor()

    ...

except mariadb.Error as ex:

    print(str(ex))

Apparently the mariadb.Connection class does not handle (or properly) handle the special _enter_ and _exit_ methods to handle entry and exit from with statements.

Attachments:
memleak-with.py can be run (modify the db_pass to root password) to show the memory growth
memleak-withfix.py contains a wrapper class which implements the _enter_ and _exit_ methods to close the connection and cursor, which does NOT have a memory leak.
