sql_union.cc:
A fix for a bug that allowed table names to be used in ORDER BY columns (But #3064)
New (simpler) internal timestamp handling.
More debuging to heap tables.
Small cleanups to multi-table-delete
false -> 0 and true -> 1 (We should use TRUE and FALSE)
Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT
Fixed mutex bug in DROP DATABASE
Fixed bug when using auto_increment as second part of a key where first part could include NULL.
Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
Don't write message to error log when slave reconnects becasue of timeout.
Fixed possible update problem when using DELETE/UPDATE on small tables
(In some cases we used index even if table scanning would be better)
A lot of minior code cleanups
(All commit emails since 4.0.1 checked)
This had to be done now, before the 4.1 tree changes to much, to make it easy to propagate bug fixes to the 4.1 tree.
accomodate EXPLAIN properly for all possible variant of UNION's
derived tables etc ...
This also fixes all reported (and unreported) bugs when EXPLAIN is
run on UNION's.
select_describe() now has a very dirty hack to avoid some problems
with transactional tables on table unlocking.
Code speedup is possible. For the moment all that was important was
that all tests are passed.
New faster list iterators
Change list code to be simpler and faster
Optimize count(distinct)
New error messages for UNION
Make create_tmp_table more general to be usable by UNION
