have been created by the last addition of new CONNECT features. The version previous to this one is a preliminary test version and should not be distributed. - Handle indexed UPDATE/DELETE. Previously this was just tested and an error message send when it could not be done. Now CONNECT can do it in all the cases. It is done by a MRR like tchnique by making a list of all update or delete to do, sort them, then execute them. modified: storage/connect/array.cpp storage/connect/array.h storage/connect/filamap.cpp storage/connect/filamap.h storage/connect/filamdbf.cpp storage/connect/filamfix.cpp storage/connect/filamfix.h storage/connect/filamtxt.cpp storage/connect/filamtxt.h storage/connect/filamvct.cpp storage/connect/filamvct.h storage/connect/filamzip.cpp storage/connect/filamzip.h storage/connect/global.h storage/connect/ha_connect.cc storage/connect/ha_connect.h - Differenciate Cardinality that returns a true or estimated table size and GetMaxSize that return a value equal or greater than the table row number. This fixes the errors of non matching opt files. modified: storage/connect/connect.cc storage/connect/tabdos.cpp storage/connect/tabdos.h storage/connect/tabfix.cpp storage/connect/table.cpp storage/connect/tabmac.h storage/connect/tabmysql.cpp storage/connect/tabmysql.h storage/connect/tabodbc.cpp storage/connect/tabodbc.h storage/connect/tabpivot.h storage/connect/tabtbl.cpp storage/connect/tabtbl.h storage/connect/tabutil.cpp storage/connect/tabutil.h storage/connect/tabwmi.h storage/connect/xtable.h - Fix some errors and issues when making index and opt files. Erase opt and index files for void tables. Fix wrong calculation of Block and Last in MakeBlockValues. Invalidate indexes before making opt file. Fully handle blocked variable tables. Make opt file for blocked variable tables even when they have no optimised colums. modified: storage/connect/tabdos.cpp storage/connect/xindex.h - Fix some errors making index Return an error when the allocation is too small (should not really occur now that GetMaxSize is sure) Don't use XXROW index for DBF tables because of soft deleted lines. modified: storage/connect/xindex.cpp - Typo modified: storage/connect/macutil.cpp storage/connect/tabdos.h storage/connect/tabsys.cpp storage/connect/tabsys.h
