Question on bug 571200
Hi there! How goes? I have a question pertaining to bug 571200. I have
hand-coded the fix from Federated as shown on
http://lists.mysql.com/commits/102419. Obviously, FederatedX has changed
enough that there's a fair amount of work I had to do (see my branch at
bzr+ssh://bazaar.launchpad.net/~capttofu/maria_bug_571200). Most of it I
think I have a good solution to. The one thing remaining is how to get
anything that pertains to getting or setting the "result->data_cursor"
value, as you'll see is in that patch. Since "result" is now a
FEDERATEDX_IO_RESULT, it doesn't have that structure member, although
FEDERATEDX_IO_RESULT for federatedx_io_mysql class is a MYSQL_RES, but
trying to access results->data_cursor results in errors such as:
ha_federatedx.cc: In member function ‘int
ha_federatedx.cc:2888: error: invalid use of incomplete type ‘struct
ha_federatedx.h:127: error: forward declaration of ‘struct
So, the solution I think is to have a virtual method in the
federatedx_io class called "get_data_cursor_pos" and
"set_data_cursor_pos" that within federatedx_io_mysql class obtains
result->data_cursor. For other driver classes, it'll require some
thinking, but for now this would get the mysql driver working.
What are your thoughts on this and what I have thus far?
Thanks, hope all is going well!
