Commit 0219ac1e authored by Olivier Bertrand's avatar Olivier Bertrand

This is a major update that fixes most of the issues and bugs that

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.

- 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.

- 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.
