I would like to recommend the following code change to the 0.9 mysql driver
code to prevent a memory leak when the driver is linked against the
thread-safe mysqlclient_r library. The if(mysql_thread_safe()) statement
should ensure that the mysql cleanup function I added for threads is not
invoked if the driver is linked against the non-reentrant mysqlclient library.
The MySQL documentation indicates that "mysql_thread_init() is automatically
called by my_init(), which itself is automatically called by mysql_init(),
mysql_library_init(),mysql_server_init(), and mysql_connect(). If you invoke
any of those functions,mysql_thread_init() will be called for you." So all
that is missing is the mysql_thread_end call.
If each thread has it's own connection, and libdbi instance, as recommended by
the libdbi documentation, this should work transparently.
Thanks,
Ethan Funk
