Hi Elena,

I've made a patch that fixes both BUG#992942 and MDEV-325. It is rather risky,
as it touches the part of the code whose interaction with other parts of the
code is not very well defined.

This is why I request RQG testing. Could you please run some test that would
use ORDER BY ... LIMIT, GROUP BY, subqueries, tables that may or may not be
read with range/index_merge access, index condition pushdown, etc?
(Yes, you may really need all of the above to trigger the problem. Check out
analysis comments in the bug).


The code is at:
bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/5.5-show-explain-test1

it is based on 5.5-show-explain, so SHOW EXPLAIN part can be tested, too.

BR
 Sergei
