Igor Babaev	56eb6d7e69	Fixed LP bug #794890. ... Changed the code that processing of multi-updates and multi-deletes with multitable views at the prepare stage. A proper solution would be: never to perform any transformations of views before and at the prepare stage. Yet it would require re-engineering of the code that checks privileges and updatability of views. Ultimately this re-engineering has to be done to provide a clean solution for INSERT/UPDATE/DELETE statements that use views. Fixed a valgrind problem in the function TABLE::use_index.	2011-06-13 19:03:03 -07:00
Igor Babaev	ab411f8f1c	Fixed LP bug #794909. ... The function generate_derived_keys did not take into account the fact that the last element in the array of keyuses could be just a barrier element. In some cases it could lead to a crash of the server. Also fixed a couple of other bugs in generate_derived_keys: the inner loop in the body of if this function did not change the cycle variables properly.	2011-06-09 12:43:28 -07:00
Igor Babaev	6d2da32461	Fixed LP bug #784848 that caused failures of func_str.test and ... derived_view.test. Do not register Item_ref objects of the type VIEW_REF as outer references.	2011-05-18 22:36:33 -07:00
Igor Babaev	704f97035f	Merged the code of MWL#106 into 5.3 ... Resolved all conflicts, bad merges and fixed a few minor bugs in the code. Commented out the queries from multi_update, view, subselect_sj, func_str, derived_view, view_grant that failed either with crashes in ps-protocol or with wrong results. The failures are clear indications of some bugs in the code and these bugs are to be fixed.	2011-05-16 22:39:43 -07:00
