276622c92d Fix for bug #5595: NULLIF() IS NULL returns false if NULLIF() returns NULL 2004-09-18 13:06:44 +04:00

154c1a0aa3 Fixed memory leak that occured after merge with 4.1 
We should not replace Item_arena in Item_bool_func2::fix_length_and_dec() if this is
conventional statement, since in this case THD::current_arena is the same as active arena
and we will overwrite arena with its older version during restore_backup_item_arena()
call.

f2829d0386 After merge fixes of merge with 4.1 that included the new arena code. 
Fixed (together with Guilhem) bugs in mysqlbinlog regarding --offset
Prefix addresses with 0x for easier comparisons of debug logs
Fixed problem where MySQL choosed index-read even if there would be a much better range on the same index
This fix changed some 'index' queries to 'range' queries in the test suite
Don't create 'dummy' WHERE clause for trivial WHERE clauses where we can remove the WHERE clause.
This fix removed of a lot of 'Using where' notes in the test suite.
Give NOTE instead of WARNING if table/function doesn't exists when using DROP IF EXISTS
Give NOTE instead of WARNING for safe field-type conversions

bdec2c603b A fix for bug#4368 '"like" fails in PreparedStatement, crashes 
server': the bug occurs when arguments of LIKE function are in 
differentcharacter sets. If these character sets are compatible, 
we create an item-converter. In prepared mode, this item
needs to be created in memory of current prepared statement.

568c6e8526 Fix for bug#4912 "mysqld crashs in case a statement is executed 
a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement 
execute a subtree with negation was replaced with equivalent 
subtree without NOTs.
The problem was that although this transformation was permanent, 
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(), 
  Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
  THD::free_temporary_pool_for_ps_preparing(); they
  were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
  prepared statement, it points at the thd. 
The rest of the patch contains mainly mechanical changes and
cleanups.

The objects of this class represent multiple conjunctive equalities
in where conditions: =(f1,f2,...fn) <=> f1=f2 and f2= ... and =fn.
The objects are used to generate new possibale paths to access
the tables when executing a query.
They are also used to optimize the execution plan 
chosen by the optimizer for the query.

07f94cb7cd Row comparison now does compare field collations, e.g. 
ROW('a','b','c) = ROW('A' collate latin1_bin,'b','c') returns 0
When a number is compared to a string, character sets and 
collations are not aggregated. e.g. this returned error in 4.1.0:

SELECT 1=_latin2'1';
because character sets was aggregated, and 1 was considered as
a string of latin1 charset during this aggregation.
