Re: [Maria-developers] Rev 2777: Make pbxt.join_nested test pass in file:///home/psergey/dev/5.1-merge-look/

Hi Kristian, I've at last figured out the join_nested issue. To sum up, it was a false alarm, the fix is to adjust the test suite and I've pushed it to the lp:~maria-captains/maria/5.1-merge tree. On Sun, Dec 27, 2009 at 07:48:33PM +0300, Sergey Petrunya wrote:

Before, two plans were competing, and that was addressed by using --sorted_result on the EXPLAIN output because they were different only in join order. Now we've got a 3rd plan which differs with "Using where" and that doesn't work anymore. - This patch fixes it by removing 'Using where' from EXPLAIN output. Test coverage is somewhat reduced but probably still ok as PBXT and nested outer join processing have no interaction and we don't expect any bugs here.
