--echo # WL#6599: New data dictionary and I_S.
|
|
--echo #
|
|
--echo # The re-implemntation of I_S as views on top of DD tables,
|
|
--echo # together with the modified way of retrieving statistics
|
|
--echo # information, introduces some differences when comparing
|
|
--echo # with the previous I_S implementation. The purpose of this
|
|
--echo # test is to focus on these behavioral differences, both
|
|
--echo # for the purpose of regression testing, and to document
|
|
--echo # the changes. The issues below refer to the items listed
|
|
--echo # in the WL#6599 text (HLS section 6).

--echo # MySQL 'DISABLE KEYS' functionality is only applicable to MyISAM
|
|
--echo # tables, but looks like its marked for InnoDB table too in trunk.
|
|
--echo # This problem is fixed now. It has been discussed with Martin Hansson
|
|
--echo # who worked on WL8697 which introduced invisible index. He agreed that
|
|
--echo # the behavior on trunk is bad and needed to be fixed. We have fixed
|
|
--echo # that now.
