them sorted by file position. Firstly a new value is stored in indexes
to know if they are sorted, preventing to do the sorting when it is not
needed. Secondly, almost all in now done in connect instead of being
done by the different file access method classes. This pepares the future
use of temporary files for all table types and also fix the bug that was
occuring when partially using a multi-column index because of false MRR
like call of position followed by unsorted rnd_pos no more using indexing.

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.

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.

Return an error when the allocation is too small (should not

1) Support of partitioning by connect. A table can be partitioned
by files, this is an enhanced MULTIPLE table. It can be also
partitioned by sub-tables like TBL and this enables table sharding.
2) Handling a CONNECT bug that causes in some cases extraneous rows
to remain in the table after an UPDATE or DELETE when the command
uses indexing (for not fixed file tables). Until a real fix is
done, CONNECT tries to ignore indexing and if it cannot do it
abort the command with an error message.
- Add tests on partitioning

in this version. Sure enough, it never caused any improvement in
the execution speed and rather caused a small increase of execution
time. This is probably because values are sorted by rowid in each
range of CONNECT indexes. This could be reconsidered if a customer
have a need for processing very big files.
- Fix a bug in ha_connect::CheckCond. The negated form of BETWEEN and
IS NULL operators was not recognized.
